6685785 AB - Spatial and temporal mismatches between coarse resolution projections of global climate models (GCMs) and fine resolution data requirements of ecosystems models are the major obstacles for assessing the site-specific climatic impacts of climate change on natural resources and ecosystems. The objectives of this study were to: (i) develop a simple method for statistically downscaling GCM monthly output at the native GCM grid scale to station-scale using transfer functions, and (ii) further demonstrate the site-specific impact assessment of climate change on water resources, soil erosion, and crop production at Kingfisher, OK, US using the water erosion prediction project (WEPP) model. Monthly precipitation and temperature projected by the UK Hadley Centre's Climate Model (HadCM3) under the GGa emissions scenario were downloaded for the periods of 1900-1999 and 2070-2099 for the grid box containing the target station. Univariate transfer functions were derived by calibrating probability distributions of GCM-projected monthly precipitation and temperature to match those of local climatology for the 1950-1999 period. Derived functions, which were tested for 1900-1949, were used to spatially downscale the HadCM3 monthly projections of 2070-2099 to the target station. Downscaled monthly data were further disaggregated to daily weather series using a stochastic weather generator (CLIGEN) for driving the WEPP model. Disaggregated daily series preserve the monthly means and variances of precipitation and temperature of the downscaled HadCM3 output. Simulated annual runoff under the changed climate, compared with the present climate, increased by 40-48% despite the projected 5% decrease in precipitation. Simulated plant transpiration, soil evaporation, and long-term soil water reserve decreased by 5, 16.5, and 5.5%, respectively. Simulated soil loss rates were increased by some 44% under conventional tillage and doubled under conservation tillage and no-till. Simulated wheat yield increased by approximately 14% in all three tillage systems. The overall results show that the proposed downscaling technique is simple and sound, which provides an effective alternative for assessing the site-specific impacts of climate change on soil erosion and crop production. Nevertheless, the technique suffers from the same shortcomings as all other statistical downscaling methods, as it largely relies upon the accuracy of GCM projections as well as the applicability of transfer functions to future climate.

AN - 68872392; 16333032 AB - The Dietary Guidelines for Americans 2005 recommends that Americans increase their intake of dairy products. However, some studies have reported that increasing dairy product intake is associated with an increased risk of prostate cancer. We conducted a meta-analysis to examine associations between intakes of calcium and dairy products and the risk of prostate cancer. We searched Medline for prospective studies published in English-language journals from 1966 through May 2005. We identified 12 publications that used total, advanced, or fatal prostate cancer as end points and reported associations as relative risks (RRs) with 95% confidence intervals (CIs) by category of dairy product or calcium intake. Data were extracted using standardized data forms. Random-effects models were used to pool study results and to assess dose-response relationships between dairy product or calcium intakes and the risk of prostate cancer. We conducted sensitivity analyses by changing criteria for inclusion of studies or by using fixed-effects models. All statistical tests were two-sided. Men with the highest intake of dairy products (RR =1.11 [95% CI = 1.00 to 1.22], P = .047) and calcium (RR = 1.39 [95% CI = 1.09 to 1.77], P = .018) were more likely to develop prostate cancer than men with the lowest intake. Dose-response analyses suggested that dairy product and calcium intakes were each positively associated with the risk of prostate cancer (Ptrend = .029 and .014, respectively). Sensitivity analyses generally supported these associations, although the statistical significance was attenuated. The pooled relative risks of advanced prostate cancer were 1.33 (95% CI = 1.00 to 1.78; P = .055) for the highest versus lowest intake categories of dairy products and 1.46 (95% CI = 0.65 to 3.25; P > .2) for the highest versus lowest intake categories of calcium. High intake of dairy products and calcium may be associated with an increased risk of prostate cancer, although the increase appears to be small.

AN - 68804078; 16168455 AB - Transposon linker insertion mutagenesis of a full-length infectious clone (IC) (pBIC) of the pathogenic classical swine fever virus (CSFV) strain Brescia was used to identify genetic determinants of CSFV virulence and host range. Here, we characterize a virus mutant, RB-C22v, possessing a 19-residue insertion at the carboxyl terminus of E1 glycoprotein. Although RB-C22v exhibited normal growth characteristics in primary porcine macrophage cell cultures, the major target cell of CSFV in vivo, it was markedly attenuated in swine. All RB-C22v-infected pigs survived infection remaining clinically normal in contrast to the 100% mortality observed for BICv-infected animals. Comparative pathogenesis studies demonstrated a delay in RB-C22v spread to, and decreased replication in the tonsils, a 10(2) to 10(7) log10 reduction in virus titers in lymphoid tissues and blood, and an overall delay in generalization of infection relative to BICv. Notably, RB-C22v-infected animals were protected from clinical disease when challenged with pathogenic BICv at 3, 5, 7, and 21 days post-RB-C22v inoculation. Viremia, viral replication in tissues, and oronasal shedding were reduced in animals challenged at 7 and 21 DPI. Notably BICv-specific RNA was not detected in tonsils of challenged animals. These results indicate that a carboxyl-terminal domain of E1 glycoprotein affects virulence of CSFV in swine, and they demonstrate that mutation of this domain provides the basis for a rationally designed and efficacious live-attenuated CSF vaccine.

We used a theoretical framework to study spatiotemporal structuring in a transient natural enemy-victim system subject to differential rates of dispersal, stochastic forcing, and nonlinear dynamics. Highly mobile natural enemies that attacked less mobile victims were locally spatially segregated from each other when governed by approximate linear dynamics. In contrast, in nonlinear dynamical systems, such as cyclic populations, interacting species achieved local aggregation with each other regardless of dispersal rates, and aggregation was enhanced specifically when highly mobile enemies attacked less mobile victims. These patterns of spatial aggregation held under varying levels of stochastic forcing. This work thus shows a range of dynamic spatial patterns in interacting-species models, and how spatial aggregation between natural enemies and victims can be achieved in locally unstable populations that are linked through dispersal.

AN - 70184213; 16921678 AB - Three biological assay procedures for repellents are currently documented in the literature: 1) ASTM E951-94, Laboratory testing of non-commercial repellent formulations on the skin. 2) ASTM E939-94, Field testing topical applications of compounds as repellents for medically important and pest arthropods. 1. Mosquitoes. 3) WHO/CTD/WHOPES/IC/96.1, Report of WHOPES informal consultation on the evaluation and testing of insecticides. One public draft set of repellent-testing guidelines is available on the internet: 4) USEPA OPPTS 810.3700, Product performance test guidelines. Insect repellents for human skin and outdoor premises. In practice, the outcome of a repellent bioassay using any of these procedures is affected by the absorption, penetration, and chemical modification of repellent on skin and by evaporation, abrasion, and perspiration. Other abiotic factors that influence mosquito responses to repellent stimuli are light, temperature, humidity, repellent dose, exposure time, and test-cage shape and size. Biotic variables in repellent bioassays are larval nutrition, carbohydrate availability for adult mosquitoes, age and parity of females, and differences in the innate attraction/ repellency of test subjects. Geographic location and seasonal and diel activity cycles in mosquitoes determine when and where repellents can be tested in the field. Critical knowledge of these sources of variation can be converted to improved precision and accuracy in repellent bioassays and the resulting information used to efficiently select new repellent compounds for toxicological evaluation and field testing.

AN - 70159720; 16601818 AB - Nowadays naturally occurring compounds with the potential antimutagenic and anticarcinogenic effects are of great importance for their prospective use in cancer chemoprevention and treatment. The new water soluble derivative of microbial polysaccharide beta-D-glucan-carboxymethyl glucan (CMG) belongs to such a category of natural substances. CMG isolated from the cell wall of baker's yeast Saccharomyces cerevisiae is included into the class of biopolymers known as biological response modifiers (BRMs) with a broad range of activities, above all ones interfering with cancer therapy. It was demonstrated on four experimental model systems that biological and consequential medicinal importance of CMG is based on the combined application with another active compound. In the Saccharomyces cerevisiae antimutagenicity assay CMG significantly reduced ofloxacin-induced mutagenicity in the yeast strain D7. CMG exerted bioprotective (anti-toxic and antimutagenic) effect after its simultaneos application with methyl methanesulphonate on the repair-deficient strain uvs10 of the unicellular green alga Chlamydomonas reinhardtii. In the Vicia sativa simultaneous phytotoxicity and anticlastogenicity assay CMG exerted statistically significant anticlastogenic efect against maleic hydrazide-induced clastogenicity in Vicia sativa L. Only in the Salmonella/microsome assay CMG did not exert statistically significant antigenotoxic effect, despite of the fact that it reduced 9-aminoacridine-induced mutagenicity in S. typhimurium TA97, but his(+) revertants decreasing was statistically significant only at the highest CMG concentration used. The data presented unambiguously documented that even biopolysaccharides (e.g., derivatives of beta-glucan) belonging to the most abundant class of natural biopolymers may contribute to cancer prevention and therapy.

(Diptera: Muscidae). AN - 70158185; 16599159 AB - Relative collections of house flies were compared on two Florida dairy farms using several monitoring methods: sticky cylinders, baited jug traps (Farnam Terminator and Victor Fly Magnet), and bait strips (Wellmark QuikStrike). Bait strips were placed over collecting pans and under 61 cm square plywood roofs to protect the toxicant from sunlight ("sheltered QuikStrike traps"). Sticky cylinders collected the fewest flies (515-679 flies/trap/day) and sheltered QuikStrike traps the most (5,659-8,814 flies/trap/day). The sheltered QuikStrike traps are promising tools for disease surveillance programs. The two baited jugs collected a similar and intermediate number of flies, with collections highest during the first 2 days after placement (2,920-5,462 flies/trap/day). Jug trap collections were low after 4 days of use in the field, apparently due to deterioration in the attractiveness of the bait over time. Jug traps collected mostly females, whereas sticky cylinders and sheltered QuikStrike traps collected mostly males. Exposure of jug trap bait (Farnam) to fly cadavers for 3 days did not increase attractiveness of the bait. Combinations of the Farnam and Victor attractants were more attractive than either attractant alone and 25-43% more attractive than expected based on the sum of collections in the single-attractant jug traps. A 25% solution of farm-grade blackstrap molasses was as effective as either of the two proprietary baits tested, offering a low-cost alternative for fly population monitoring.

AN - 70144314; 16539113 AB - Anoplophora glabripennis (Motschulsky), has recently (since 1996) established in limited infestations near several cities in the United States. A. glabripennis was probably introduced into the United States with solid wood packing or dunnage. During 2001, we evaluated the current APHIS Schedule T404-b-1-1 for methyl bromide (MeBr) fumigation. Fumigations were conducted in 432-liter Lexan chambers inside a 6.1-m refrigerated container. Each fumigation consisted of 12 high-moisture, naturally infested Populus spp. timbers. We fumigated wood for 24 h at 4.4 degrees C (80 g/m3), 10.0 degrees C (64 g/m3), 15.6 degrees C (56 g/m3), and 21.1 degrees C (48 g/m3). All schedule doses resulted in 100% kill of A. glabripennis larvae. During 2002, we conducted additional fumigations to determine the basic toxicity of MeBr to A. glabripennis larvae in solid wood timbers of 10 by 10 by 115-cm size. Probit analysis estimated the CxT product at 99.0, 99.9, 99.99, and 99.99683% kill (probit-9). The probit-9 values for CxT were 1,196.1, 918.7, 642.4, and 362.4 g-h/m3 at 4.4, 10.0, 15.6, and 21.1 degrees C, respectively. Applied doses to achieve this level of control were estimated to be 119.6, 82.7, 56.0, and 32.2 g/m3, respectively. These applied doses are satisfactory for wood as a commodity with wood load factors of approximately 25% and may be higher than necessary for container fumigation where sorptive wood load as crating or pallets may only be 5% or less. The APHIS Schedule T404-b-1-1 is adequate if extended for 24 h and should be amended to include intermediate doses at 10.0 and 15.6 degrees C, thus reducing the use of MeBr at these temperatures.

AN - 70144159; 16539122 AB - The current standard practice of two to three preemptive insecticide applications at the start of pinhead (1-2-mm-diameter) squaring followed by threshold-triggered (whenever 10% of randomly selected squares have oviposition punctures) insecticide applications for boll weevil, Anthonomus grandis grandis Boheman, control does not provide a reliably positive impact on cotton, Gossypium hirsutum L., yields in subtropical conditions. This study showed that four fewer spray applications in a "proactive" approach, where spraying began at the start of large (5.5- 8-mm-diameter) square formation and continued at 7- to 8-d intervals while large squares were abundant, resulted in fewer infested squares and 46-56% more yield than the standard treatment at two locations during 2004. The combination of fewer sprays and increased yield made the proactive approach 115-130% more profitable than the standard. The proactive approach entails protection only at the crop's most vulnerable stage (large squares) that, as a source of food, accelerates boll weevil reproduction. In contrast, the standard approach protects early season small squares and later season bolls, both of which contribute less to boll weevil reproduction than large squares. Proaction is an in-season crop protection approach that can be used to increase yield in individual fields during the same season and that could be incorporated into boll weevil eradication strategy that involves later diapause sprays. Because proaction is based on an important relationship between the cotton plant and boll weevil reproduction, the tactic will probably be effective regardless of climate or region.

Monitors were located adjacent (1-3 m) to the buildings. Soil around and under the buildings was treated with 0.05% imidacloprid. None of the termites collected showed latent mortality attributed to imidacloprid intoxication. Imidacloprid soil treatments did not measurably reduce C. formosanus populations adjacent to the treatments. Imidacloprid does not seem to fit the liquid-bait model.

AN - 70143768; 16539119 AB - Bait sprays containing the toxicant spinosad (GF-120) were applied to citrus groves in the Rio Grande Valley of Texas where Mexican fruit flies were detected in surveillance traps. The sprays were applied as a supplement to a continuous sterile insect release program. Sterile fly captures were 47-63% lower in the treated groves compared with control groves. Eight of 10 secondary pest populations declined in the test groves subsequent to spray applications, but they also declined in the control groves, suggesting that the decline was a seasonal phenomenon rather than a result of the bait sprays. Citrus whitefly, Dialeurodes citri (Ashmead), populations increased modestly and citrus blackfly, Aleurocanthus woglumi (Ashby), populations remained unchanged compared with pretreatment levels. Thus, no outbreaks of secondary pests occurred as a result of the spinosad bait sprays in this instance, as has been reported for malathion bait sprays in citrus. The bait sprays had no detectable effect on populations of specific indicator species of parasitoids (including Aphytis spp. and Comperiella bifasciata Howard), or on numbers of beneficial insects in general, in the treated groves.

AN - 70141332; 16539162 AB - As part of the ongoing evaluation of different systemic insecticides for prophylactic treatment of trees, responses of the beetle Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae) to different doses of four systemic neonicotinyl insecticides were studied. Adult beetles were provided with twigs or leaves of trees treated with different concentrations of imidacloprid to evaluate the toxicity of the insecticide through ingestion or contact or through both. Adult beetles also were provided with twigs of host plant treated with clothianidin, dinotefuran, and thiamethoxam to establish dose response of the beetle to these insecticides. Levels of individual insecticides in twigs and leaves were determined by using the "parent" method with high-performance liquid chromatography, and these levels were compared with the applied concentrations to determine their relationship. The LC50 values for detected level of each insecticide in twigs was 5.1 ppm at 24 h, 2.9 at 48 h, and 1.9 ppm at 72 h for imidacloprid; 1.1 ppm at 72 h for clothianidin; 2.2 ppm at 72 h for dinotefuran; and 1.0 ppm at 72 h for thiamethoxam. Our results indicate that mortality of adult beetles resulted not only from the ingestion and contact toxicity but also possibly from the antifeedant effect of imidacloprid.

AN - 70131958; 16479955 AB - Salmonella is the most important human pathogen associated with shell eggs. Salmonella Enteritidis is the serotype most often implicated in outbreaks, although other serotypes have been recovered from eggs and from the commercial shell egg washing environment. Many sample methods are used to recover microorganisms from eggshells and membranes. A shell rinse and modified shell-and-membrane crush method for recovery of Salmonella were compared. Eggs were collected from 3 commercial shell-washing facilities (X, Y, and Z) during 3 visits. Twelve eggs were collected from each of 10 to 12 locations along the egg processing chain. After being transported back to the laboratory, each egg was sampled first by a shell rinse method and then by a shell crush method. For each technique (rinse or crush), 2 pools of 5 eggs per location sampled were selectively enriched for the recovery of Salmonella. Presumptive samples positive for Salmonella were confirmed serologically. Overall, there were 10.1% (40/396) Salmonella-positive pooled samples. Salmonella were recovered by the shell rinse and shell crush techniques (4.8 vs. 5.3%, respectively). Plant X yielded 21.5% Salmonella positives, whereas less than 5% of samples from plants Y and Z were found to be contaminated with the organism (4.2 and 4.5%, respectively). Salmonella was recovered more often from unwashed eggs (15.8%) than from washed eggs (8.3%). For some eggs, Salmonella was only recovered by one of the methods. Use of both approaches in the same experiment increased sampling sensitivity, although in most cases, crushing provided more sensitive Salmonella recovery.

AN - 70118900; 16462862 AB - The objective of this study was to evaluate the ability of the Aspergillus flavus pAF28 DNA probe to produce DNA fingerprints for distinguishing among genotypes of Petromyces alliaceus (Aspergillus section Flavi), a fungus considered responsible for the ochratoxin A contamination that is occasionally observed in California fig orchards. P. alliaceus (14 isolates), Petromyces albertensis (one isolate), and seven species of Aspergillus section Circumdati (14 isolates) were analyzed by DNA fingerprinting using a repetitive sequence DNA probe pAF28 derived from A. flavus. The presence of hybridization bands with the DNA probe and with the P. alliaceus or P. albertensis genomic DNA indicates a close relationship between A. flavus and P. alliaceus. Twelve distinct DNA fingerprint groups or genotypes were identified among the 15 isolates of Petromyces. Conspecificity of P. alliaceus and P. albertensis is suggested based on DNA fingerprints. Species belonging to Aspergillus section Circumdati hybridized only slightly at the 7.0-kb region with the repetitive DNA probe, unlike the highly polymorphic hybridization patterns obtained from P. alliaceus and A. flavus, suggesting very little homology of the probe to Aspergillus section Circum dati genomic DNA. The pAF28 DNA probe offers a tool for typing and monitoring specific P. alliaceus clonal populations and for estimating the genotypic diversity of P. alliaceus in orchards, vineyards, or crop fields.

AN - 68896424; 16355847 AB - Sixty-one Listeria monocytogenes strains from raw milk were analyzed with an automated repetitive element-based PCR (rep-PCR) system to examine the utility of this system for serotype grouping and to determine whether specific regional relationships could be identified. Results of the similarity analysis revealed two primary clusters of L. monocytogenes isolates. Cluster 2 exclusively contained serogroup 1/2a isolates; however, two 1/2a isolates were also found in cluster 1. Isolates of serogroups 1/2b, 4b, 3b, and 4c were also in cluster 1. Clusters 1 and 2 were separated at a relative similarity of 86%. Listeria species other than L. monocytogenes (L. ivanovii, L. seeligeri, L. welshimeri, L. grayi, and L. innocua) had similarity scores of less than 80% in pairwise comparisons with the L. monocytogenes isolates. Thus, this method may be useful for species identification once an isolate is characterized as Listeria. When rep-PCR fingerprints of the L. monocytogenes 1/2a isolates were compared, there was no apparent regional grouping. However, discrimination between isolates suggests that the rep-PCR assay might be useful for tracking L. monocytogenes 1/2a and for tracking isolates across regions or within smaller ecological niches. The automated rep-PCR method could not discriminate between serotypes 1/2b and 4b but may be useful for discriminating between 1/2a and other serotypes and for tracking isolates within serotype 1/2a.

AN - 68879723; 16336710 AB - Populations of Homalodisca coagulata (Say) were sampled from citrus orchards in southern California, USA to characterize and quantify seasonal occurrences of nymphs and adults with the goal of identifying management opportunities through well-timed treatments and/or natural enemy releases. Higher densities of H. coagulata in 2001 contributed to a complete seasonal profile that began in early spring with the emergence of first instar nymphs and their progression through five nymphal instars lasting until mid-August. Adult emergence began in mid-June with peak adult densities attained from mid to late August followed by a gradual decline through autumn. A persistent and significant male bias was observed in the adult sex ratio from the time of first emergence through mid-October in oranges; the same trend was present in lemons, but with more variability. Adult densities gradually declined through the winter months into the following spring before rapidly increasing again in June as the 2002 spring generation of nymphs began emerging as adults. The seasonal timing of nymphs and adults in 2002 was nearly identical to that observed the previous year. Phenology data from both years were incorporated into a stochastic, temperature-dependent model that predicts the occurrences of H. coagulata stages through time. Applications of imidacloprid early in the spring generation of nymphs proved very effective at reducing nymphs and sustaining lower densities of adults through summer.

AN - 68872462; 16332793 AB - Pulsed-field gel electrophoresis and serotyping were performed for 544 isolates of Listeria monocytogenes, including 502 isolates recovered from contaminated samples from 31,705 retail ready-to-eat (RTE) food products and 42 isolates recovered from human cases of listeriosis. The isolates were from Maryland (294 isolates) and California (250 isolates) and were collected in 2000 and 2001. The isolates were placed into 16 AscI pulsogroups (level of relatedness within each group, > or =66%), 139 AscI pulsotypes (levels of relatedness, > or =25% to 100%), and eight serotypes (serotypes 1/2a, 1/2b, 1/2c, 3a, 3b, 4b, 4c, and 4d). The most frequently found pulsotypes belonged to either pulsogroup A (150 food isolates plus 4 clinical isolates) or pulsogroup B (104 food isolates plus 5 clinical isolates). The majority of the 502 food isolates were either serotype 1/2a (298 isolates) or serotype 1/2b (133 isolates), whereas the majority of the 42 clinical isolates were either serotype 1/2a (19 isolates) or serotype 4b (15 isolates). Additionally, 13 clinical isolates displayed pulsotypes also found in food isolates, whereas the remaining 29 clinical isolates displayed 24 unique pulsotypes. These data indicate that most (86%) of the L. monocytogenes subtypes found in the RTE foods sampled belonged to only two serotypes and that 90% of the isolates displayed 73 pulsotypes, with 107 isolates displaying pulsotype 1. These data should help define the distribution and relatedness of isolates found in RTE foods in comparison with isolates that cause listeriosis.

AN - 68835636; 16304614 AB - There is relatively little information available concerning the physiological and biochemical interactions between whiteflies and their parasitoids. In this report, we describe interactions between aphelinid parasitoids and their aleyrodid hosts that we have observed in four host-parasite systems: Bemisia tabaci/Encarsia formosa, Trialeurodes vaporariorum/E. formosa, B. tabaci/Eretmocerus mundus, and T. lauri/Encarsia scapeata. In the absence of reported polydnavirus and teratocytes, these parasitoids probably inject and/or produce compounds that interfere with the host immune response and also manipulate host development to suit their own needs. In addition, parasitoids must coordinate their own development with that of their host. Although eggs are deposited under all four instars of B. tabaci, Eretmocerus larvae only penetrate 4th instar B. tabaci nymphs. A pre-penetrating E. mundus first instar was capable of inducing permanent developmental arrest in its host, and upon penetration stimulated its host to produce a capsule (epidermal in origin) in which the parasitoid larva developed. T. vaporariorum and B. tabaci parasitized by E. formosa initiated adult development, and, on occasion, produced abnormal adult wings and eyes. In these systems, the site of parasitoid oviposition depended on the host species, occurring within or pressing into the ventral ganglion in T. vaporariorum and at various locations in B. tabaci. E. formosa's final larval molt is cued by the initiation of adult development in its host. In the T. lauri-E. scapeata system, both the host whitefly and the female parasitoid diapause during most of the year, i.e., from June until the middle of February (T. lauri) or from May until the end of December (E. scapeata). It appears that the growth and development of the insects are directed by the appearance of new, young foliage on Arbutus andrachne, the host tree. When adult female parasitoids emerged in the spring, they laid unfertilized male-producing eggs in whiteflies containing a female parasitoid [autoparasitism (development of male larvae utilizing female parasitoid immatures for nutrition)]. Upon hatching, these male larvae did not diapause, but initiated development, and the adult males that emerged several weeks later mated with available females to produce the next generation of parasitoid females. Thus, the interactions that exist between whiteflies and their parasitoids are complex and can be quite diverse in the various host-parasitoid systems. Copyright 2005 Wiley-Liss, Inc.

AN - 68769896; 16189844 AB - Greenhouse and field studies were conducted to investigate response of two rice varieties, Priscilla and Cocodrie, to sub-lethal rates of glyphosate in terms of injury, shikimate accumulation and yield. In the greenhouse, more shikimate accumulated in Cocodrie than Priscilla at comparable glyphosate rates applied to plants at the three-leaf stage. In field studies, glyphosate was applied to both varieties when they were 74-cm tall and in the internode separation growth stage. Visual injury, plant height, and leaf-tissue samples for shikimate analysis were collected at 3, 7, 14, 21 and 28 days after treatment (DAT). Rice yield was also determined. Noticeable visual injury and height reduction to both varieties was observed as early as 7 and 3 DAT in Cocodrie and Priscilla, respectively. Shikimate levels in leaves began to increase in both varieties by 3 DAT in a dose-dependent manner and reached a peak between 7 and 14 DAT. Elevated shikimate levels were still detectable by 28 DAT. Similar levels of shikimate accumulated in both varieties at comparable glyphosate rates. However, glyphosate treatment at comparable rates reduced rice yields more in Cocodrie than in Priscilla. The highest rate of glyphosate reduced yield in Cocodrie by 92% whereas there was only a 60% yield reduction in Priscilla. Shikimate levels in glyphosate-treated rice were strongly correlated to yield reductions across both varieties and appeared to be a better predictor of yield reduction than was visual injury. Visual injury coupled with measured shikimate levels can be used collaboratively to identify glyphosate exposure and estimate subsequent rice yield reductions.

We argue that the greater incidence of professional human capital among Chinese immigrants helps this group acculturate more quickly than Mexicans, who are more likely to be labor immigrants and that as a result, Chinese immigrants will be more likely than Mexican immigrants to participate in nature-based outdoor recreation activities. We also posit that US-born Chinese have a greater likelihood of participation compared to US-born Mexicans. Results show Chinese immigrant participation is distinguished only slightly from Mexican immigrant participation; no differences were found between US-born Chinese and US-born Mexicans. Within-group comparisons show immigrant Chinese participation to be more aligned with US-born Chinese participation than immigrant Mexican participation to US-born Mexican participation. Results from this study are intended to help raise awareness among environmental professionals of the different ways nature may be perceived by various cultural groups and also to alert managers of the important role natural resources can play in acculturating immigrants to US society.

To aid in the development of more effective management strategies, molecular markers are needed to examine the genetic structure of Canada thistle populations. Microsatellite (simple sequence repeat) markers were developed and intersimple sequence repeat (ISSR) markers were tested for North American populations. An average of nine polymorphic alleles per microsatellite locus and 11 per ISSR locus were detected. These will be used to examine the genetic structure of C. arvense in the northern Great Plains and their transferability to endemic Cirsium spp. JF - Molecular Ecology Notes AU - Slotta, Tracey ABodo AU - Foley, Michael E AU - Horvath, David AD - T.

The "turgor control model" suggested that the primary osmoregulatory signal in Enterobacteriaceae is turgor loss, which induces the kdp K super(+) transport operon and activates the Trk K super(+) permease. The ensuing increase in cytoplasmic K super(+) concentration was proposed to be the signal that turns on all secondary responses, including the induction of the proU (proline-glycine betaine transport) operon. The "ionic strength model" proposed that the regulatory signal for all osmotically controlled responses is the increase in the cytoplasmic ionic strength or macromolecular crowding after an osmotic upshift. The assumption in the turgor control model that the induction of kdp is a primary response to osmotic shock predicts that this response should precede all secondary responses. Both models predict that the induction of all osmotically activated responses should be independent of the chemical nature of the solute used to impose osmotic stress. We tested these predictions by quantitative real-time reverse transcription-PCR analysis of the expression of six osmotically regulated genes in Salmonella enterica serovar Typhimurium. After shock with 0.3 M NaCl, proU was induced at 4 min, proP and rpoS were induced at 4 to 6 min, kdp was induced at 8 to 9 min, and otsB and ompC were induced at 10 to 12 min. After an equivalent osmotic shock with 0.6 M sucrose, proU was induced with kinetics similar to those seen with NaCl, but induction of kdp was reduced 150-fold in comparison to induction by NaCl. Our results are inconsistent with both the turgor control and the ionic strength control models.

To illustrate this potential, I looked at two previous studies that focused on the recreational use of urban trails and reanalyzed the data from an active living perspective. In Study 1, individual, social and environmental factors helped distinguish between low, moderate, and high activity level trail uses. In Study 2, use patterns helped distinguish between health-motivated trail users and individuals using trails for recreation and other purposes, but perceptual and demographic data were similar among groups. Findings from similar studies can help inform active living research, and recreation and leisure studies can provide leadership and contributions to a transdisciplinary understanding of active living.

AN - 20360858; 7577405 AB - Oyster producers in the Pacific Northwest region of the United States export large quantities of oysters to international markets. Proposed changes to international limits for heavy metals content in shellfish could drastically curtail exports and impact the viability of this environmentally-friendly industry. "Supply-side" solutions such as moving oyster farms to uncontaminated sites or short-term depuration would incur substantial costs in terms of labor and infrastructure and displace workers in already economically challenged coastal communities, whereas selective breeding could benefit both producers and consumers within the current infrastructure. We studied the feasibility of selective breeding to reduce heavy metal content through a quantitative genetic analysis of heavy metals accumulation in the Pacific oyster, Crassostrea gigas by opportunistically sampling a factorial mating experiment initiated in 2000 to study the effects of parent size on offspring growth and survival. The experiment consisted of all possible crosses among six males (sires) and five females (dams). At harvest, we measured four performance traits (yield, survival, whole oyster live weight and shucked meat dry weight) and the accumulated levels of four heavy metals (copper, lead, zinc and cadmium). Analyses of variance testing for sire and dam effects and bootstrap estimates of heritability showed that all of these traits have a genetic basis. Further, half-and full-sib family means correlations revealed genetic trade-offs between copper and cadmium content and performance traits. Preliminary indications are that selective breeding to reduce heavy metals accumulation is possible, but that genetic trade-offs between metal content and performance should be taken into account in designing any program of selective breeding in this species.

Such development can have important effects on ecosystem processes and landscape patterns. It can also constrain forest management on public lands, influencing tree species composition and age structure at the landscape scale. We used the forest landscape simulation model LANDIS-II to analyze changes to the landscape patterns of tree species composition, age structure, windthrow disturbance, and aboveground live biomass across a range of constraints to public forest timber harvests on a northern Wisconsin landscape. Our results demonstrate that decreasing harvest area through the use of buffers reduces the dominance of early-successional species, increases the dominance of mid to later-successional species, and shifts the stand age distribution within the landscape toward older forests. These buffers increase the spatial heterogeneity of dominant species and age structure at the landscape scale, and lead to more windthrow disturbance. We believe that our study can inform policymakers, forest managers, and scientists about potential long-term landscape-level effects of interaction between residential development and forest management.

SIM News 53:56-61] many novel oxygenated fatty acids produced from linoleic acid by Bacillus megaterium ALA2: 12,13,17-trihydroxy-9(Z)-octadecenoic acid (12,13,17-THOA); 12,13,16-trihydroxy-9(Z)-octadecenoic acid (12,13,16-THOA); 12-hydroxy-13,16-epoxy-9(Z)-octadecenoic acid; and 12,17; 13,17-diepoxy-16-hydroxy-9(Z)-octadecenoic acid. 12,13,17-THOA, the main product, has antiplant pathogenic fungal activity. To develop an industrial process for the production of these new oxygenated fatty acids by strain ALA2, the effect of environmental factors on the production and their impact on the amount of various products were studied. Dextrose at 5 g/l was the optimum amount for the carbon source. A combination of 15 g yeast extract and 10 g tryptone showed good results as nitrogen sources. Among the metal ions tested, the optimum concentrations for the reaction for the different ions were as follows (in mM): magnesium 2.0, iron 0.5, zinc 0.1, nickel 0.01, and cobalt 0.05. Copper ions did not affect the production of oxygenated products; however, manganese ions inhibited the reaction. Addition of these metal ions did not alter the distribution of products. The optimum temperature and pH for the production of THOAs were 30 degree C and pH 6.5. Time course studies showed 40-48 h is the optimum for the production of both THOAs. These data provide the basis for engineering scale-up production of these new products.

A CM-5 sensor chip previously reacted with ethylenediamine to produce an aminoethyl group was coupled with 4-carboxybutyl zilpaterol activated using EDC/NHS. Five polyclonal and four monoclonal antibodies were screened for their suitability to detect low levels of zilpaterol using the biosensor technology. Total binding was greater for polyclonal than monoclonal antibodies, but a less diluted antibody solution was required for polyclonal antibodies. A fixed antibody concentration and various concentrations of zilpaterol were injected to obtain a standard curve for each antibody to allow for B sub(0) and IC sub(50) determination. The stability of the assay was assessed by the consistency of B sub(0) in repeated experiments extending at least six hours. A measure of non-specific binding allowed the assessment of the specificity of the antibody-immobilized ligand interaction. The effect of varying concentrations of urine on B sub(0) and IC sub(50) was evaluated to assess the degree of "matrix" effect that would be present in an assay. Based on these criteria the most promising antibody (2E10, a monoclonal antibody) was selected for further evaluation. This antibody had good sensitivity with IC sub(50)=4.47 plus or minus 0.41 ng/ml (n=11) in buffer). Both intra- and inter-assay variation studies showed excellent recovery and reproducibility for concentrations between 2 ng/ml and 8 ng/ml. A comparison of the biosensor method with a previously developed ELISA demonstrated that both methods give equivalent results (slope of the correlation plot = 1.02) with a high correlation (r super(2) =0.91) between them.

Seven additional southern Sierra populations were tested at PS. Results provide guidance to forest managers seeking to reforest ponderosa pine after large wildfires or to improve productivity of plantations. PS represented warm, moist, lower mixed-conifer sites in the central Sierra. CH represented colder, drier climates at the southern limit of the Cascades in upper elevation mixed-conifer. High inherent site productivity at PS was reduced by topsoil displacement and brush competition for moisture and/or nutrients. Contrasting magnitudes and patterns of growth among provenances were expressed between sites. The local provenance at PS outgrew more distant sources by 12 to 74%. However, high elevation, nonlocal Sierra sources grew best at CH, where volume decreased with source latitude and increased with source elevation. All sources had stockier form at CH. In both tests, Sierra sources outgrew and were stockier than Cascade sources; stockiness increased with source elevation. Current results at CH support matching provenance elevation with site, using southern sources. Results at PS strongly support the use of local seed, with allowance for transferring seed to adjacent zones. FOR. SCI. 51(6):595 - 607.

ER - TY - JOUR T1 - Pathogenicity and In Planta Mycotoxin Accumulation Among Members of the Fusarium graminearum Species Complex on Wheat and Rice AN - 20241572; 6738690 AB - Fusarium head blight (FHB), or scab, is a destructive disease of small grains caused by members of the Fusarium graminearum species complex, comprised of at least nine distinct, cryptic species. Members of this complex are known to produce mycotoxins including the trichothecenes deoxynivalenol (DON) along with its acetylated derivatives and nivalenol (NIV). In this study, 31 strains, belonging to eight species of this complex and originating from diverse hosts or substrates, were tested for differences in aggressiveness and mycotoxin production. Large variation among strains, both in terms of their aggressiveness and the ability to produce trichothecenes on a susceptible cultivar of wheat was found; variation appears to be a strain-specific rather than species-specific characteristic. While pathogenicity was not influenced by the type of mycotoxin produced, a significant correlation was observed between the amount of the dominant trichothecene (DON and its acetylated forms or NIV) produced by each strain and its level of aggressiveness on wheat. Some isolates also were tested for their ability to infect rice cv. M201, commonly grown in the United States. While tested strains were capable of infecting rice under greenhouse conditions and causing significant amount of disease, no trichothecenes could be detected from the infected rice florets.

The identification of a new RWA biotype in the USA virulent to all commercially grown winter wheats poses new challenges to wheat breeders. Wheat germplasm was evaluated to identify accessions resistant to the new virulent RWA isolate (biotype 2). Eleven biotype 1-resistant wheats and one susceptible check were challenged with RWA biotype 2. Two resistant wheat entries were identified (one highly resistant and one moderately resistant).

The orange peel oligosaccharide fraction contained glucose in addition to rhamnogalacturonan and xylogalacturonan pectic oligosaccharides. Twenty-four-hour, temperature- and pH-controlled, stirred anaerobic fecal batch cultures were used to determine the effects that oligosaccharides derived from orange products had on the composition of the fecal microbiota. The effects were measured through fluorescent in situ hybridization to determine changes in bacterial populations, fermentation end products were analyzed by high-performance liquid chromatography to assess short-chain fatty acid concentrations, and subsequently, a prebiotic index (PI) was determined. Pectic oligosaccharides (POS) were able to increase the bifidobacterial and Eubacterium rectale numbers, albeit resulting in a lower prebiotic index than that from fructo-oligosaccharide metabolism. Orange albedo maintained the growth of most bacterial populations and gave a PI similar to that of soluble starch. Fermentation of POS resulted in an increase in the Eubacterium rectale numbers and concomitantly increased butyrate production. In conclusion, this study has shown that POS can have a beneficial effect on the fecal microflora; however, a classical prebiotic effect was not found. An increase in the Eubacterium rectale population was found, and butyrate levels increased, which is of potential benefit to the host.

Over the concentration range 11-180 ppm azadirachtin, no mortality of adult psyllids was observed when exposed to treated plants. Adult psyllids demonstrated a small but significant repellent effect from treated plants in a choice experiment, but showed no preference to oviposit on treated or untreated plants. Psyllid nymphs were susceptible to azadirachtin at very low concentrations and activity perhaps was due to developmental inhibition. At a concentration of 22.5 ppm azadirachtin, ecdysis was not observed past 4 days after treatment and all nymphs were dead within 7 days. The densities of psyllid nymphs on treated plants exposed to a greenhouse population were significantly reduced by concentrations as low as 10 ppm azadirachtin. Over the range of concentrations used in these experiments, the product caused no phytotoxicity to tender foliage of either citrus or orange jasmine plants. Field trials are warranted to determine suitability of neem-based biopesticides for inclusion in citrus integrated pest management programs.Original Abstract: Los efectos biologicos de un bioplaguicida producido en base de neem, que contiene 4.5% de azadirachtina, fueron evaluados contra el psilido asi.tico de los citricos, Diaphorina citri Kuwayama, una plaga recien introducida y vector potencial de enfermedades en citricos en los Estados Unidos. Atravez de un rango de concentracion de 11-180 ppm de azadirachtina, ninguna mortalidad en los adultos de psilidos fue observada cuando fueron expuestos a plantas tratadas. Los adultos de psilidos demonstraron un pequeno pero significativo efecto repelente en las plantas tratadas en un experimento de seleccion, pero no mostraron ninguna preferencia para ovipositar en plantas tratadas o no tratadas. Las ninfas de los psilidos fueron susceptibles a la azadirachtina en concentraciones muy bajas y la actividad posiblemente fue debida a la inhibicion para desarrollarse. En la concentracion de 22.5 ppm de azadirachtina, no se observo la ecdisis despues de 4 dias del tratamiento y todas las ninfas estuvieron muertas en un periodo de 7 dias. La densidad de las ninfas de psilidos sobre plantas tratadas expuestas a una poblacion del invernadero fue reducida significativamente por concentraciones tan bajas como 10 ppm de azadirachtina. Sobre todo el rango de concentraciones usadas en estos experimentos, el producto no causo fitotoxicidad al follaje tierno de los citricos o en planta Murraya paniculata. Es necesario hacer mas pruebas de campo para determinar el uso de los bioplaguicidas con el base de neem para incluirlos en programas de manejo integrado de plagas en citricos.

Insect populations can be monitored during the season to determine when the densities exceed an economic threshold that requires treatment, often as an insecticide application. We developed a simulation model where insect populations varied in exponential growth in fields and dispersed to adjacent fields each day of a season. The first model monitored populations of individual fields in a grid of fields and treated any field with insecticide if it exceeded a threshold population (asynchronous model) as done in traditional IPM. The second model treated the entire grid of fields with insecticide when the average population of all fields exceeded the threshold (synchronous model). We found that the synchronous model at all growth and dispersal rates tested had average field populations during a season that were significantly lower and required fewer treatments than the asynchronous method. Parameters such as percentage of fallow fields, number of fields, and treatment threshold had little affect on relative differences between the two models. The simulations indicate that cooperation among growers in areawide monitoring of fields to obtain an average population estimate for use in treatment thresholds would result in significantly less insect damage and fewer insecticide treatments. The synchronous method is more efficient because population refugia are precluded from which dispersal could reintroduce insects.

Aphid weight was used as an index of prey quality. Larvae of C. maculata were reared to pupation on aphids that had consumed transgenic or nontransgenic (susceptible) corn plants. Larval duration, survivorship to pupation, postmortem adult dry weight (taken at 30 d after eclosion), adult mobility, and fecundity were compared for C. maculata between treatments. Fitness parameters of C. maculata were similar between transgenic and susceptible treatments, despite a 33% reduction in the weight of aphid prey reared on MON 863. Using immunostrip tests, Cry3Bb1 was detectable in the leaves of MON 863 but not in the susceptible plant, aphids, or C. maculata that were fed aphids. We conclude that transgenic corn that expresses Cry3Bb1 does not inflict acute or chronic degradations in fitness on individual C. maculata through aphid prey, but these results do not necessarily apply to other natural enemies, herbivores, or insect-resistant corn hybrids.

L. hesperus is a major pest of cotton and other seed crops in the San Joaquin Valley. Mark recapture experiments were performed that measured movement and abundance of L. hesperus in cotton (Gossypium hirsutum L.), alfalfa (Medicago sativa L.), and blackeye bean (Vigna sinensis L.). Male L. hesperus moved farther than females (4.6 versus 3.6 m/d). Movement was greater in the east-west axis than the north-south axis (7.0 versus 2.4 m/d). Calculations based on mark-recapture data suggest that a random walk model describes L. hesperus dispersal well. Diffusion estimates predict 98% movement radiuses in cotton, alfalfa, and bean as 15.6, 14.4, and 7.3 m/d, respectively. Estimates of absolute L. hesperus abundance were 45,000/ha in alfalfa during the August peak, approximately five times those in cotton. The results suggest that management of L. hesperus may be affected by greater dispersal along the east-west axis and the strong male bias in sweep-net samples.

All three components require knowledge of the boundaries that delimit these areas. Additional interest is also placed on the relationship between population spread and defoliation to prepare for the gypsy moth advance in new areas and minimize its impact. We developed relationships between advancing population boundaries, which were estimated using an algorithm implemented under the USDA Forest Service Gypsy Moth Slow-the-Spread Project and defoliation records collected by State and Federal agencies. We used current data from Wisconsin, West Virginia, and Virginia and historical data from the lower peninsula of Michigan. We observed that in West Virginia, Virginia, and Michigan, defoliation generally occurred in areas where moth abundance exceeded 300 male moths per pheromone-baited trap (i.e., the 300-moth population boundary), whereas in Wisconsin, it generally occurred between the 100- and 300-moth population boundaries. We also detected temporal changes in Michigan in the relationship between boundaries and defoliation, where the transition time between the 10-moth population boundary and defoliation was 4-5 yr. Recent data from Wisconsin suggest a similar transitional time, whereas recent data from West Virginia and Virginia do not seem to contradict an earlier study suggesting a transition time of roughly 8 yr.

The mortality of boll weevil immature stages was 100% at 12 degree C and decreased to 36.4% as the temperature increased to 25 degree C. When the temperature increased from 30 degree C to 45 degree C, the mortality of weevils also increased from 50.1% to 100%. From 15 degree C to 35 degree C, the bollweevilpreimaginal development rate was linearly related to temperature. The average development time of total boll weevil immature lifestages decreased 3.6-fold and the preovipositional period decreased 3.3-fold when the temperature was increased from 15 degree C to 30 degree C. The lower threshold for development was estimated at 10.9, 6.6, 7.0, and 9.0 degree C for eggs, larval, pupal, and total immature stages, respectively, with total thermal time requirement to complete immature stages of 281.8 DD (degree day) (15 degree C) and 247.8 DD (35 degree C). At 1LC and 46 degree C, weevil females did not oviposit. Longevity of adult females decreased 4.6-fold with increasing temperatures from 15 degree C to 35 degree C. Fecundity increased with increasing temperatures up to 30 degree C and significantly decreased thereafter. These findings will be useful in creating a temperature-based degree-day model for predicting the occurrence of key life stages in the field. An accurate predictor of a pest's development can be very important in determining sampling protocols, timing insecticide applications, or implementing an integrated pest management control strategy targeting susceptible life stages.

Movement of insects between Bt crops and refuges of non-Bt crops is essential for the refuge strategy because it increases chances that resistant adults mate with susceptible adults from refuges. Conclusions about optimal levels of movement for delaying resistance are not consistent among previous modeling studies. To clarify the effects of movement on resistance evolution, we analyzed simulations of a spatially explicit model based partly on the interaction of pink bollworm, Pectinophora gossypiella (Saunders), with Bt cotton. We examined resistance evolution as a function of insect movement under 12 sets of assumptions about the relative abundance of Bt cotton (50 and 75%), temporal distribution of Bt cotton and refuge fields (fixed, partial rotation, and full rotation), and spatial distribution of fields (random and uniform). The results show that interactions among the relative abundance and distribution of refuges and Bt cotton fields can alter the effects of movement on resistance evolution. The results also suggest that differences in conclusions among previous studies can be explained by differences in assumptions about the relative abundance and distribution of refuges and Bt crop fields. With fixed field locations and all Bt cotton fields adjacent to at least one refuge, resistance evolved slowest with low movement. However, low movement and fixed field locations favored rapid resistance evolution when some Bt crop fields were isolated from refuges. When refuges and Bt cotton fields were rotated to the opposite crop type each year, resistance evolved fastest with low movement. Nonrecessive inheritance of resistance caused rapid resistance evolution regardless of movement rate. Confirming previous reports, results described here show that resistance can be delayed effectively by fixing field locations and distributing refuges uniformly to ensure that Bt crop fields are not isolated from refuges. However, rotating fields provided better insect control and reduced the need for insecticide sprays.

Ninety-six white composite (Large White x Landrace) finishing barrows (83.6 plus or minus 1.2 kg BW) were assigned to receive zero or two pSTSR implants (4 mg pST/d) and to consume one of six diets differing in total Lys concentration (0.29, 0.52, 0.75, 0.98, 1.21, or 1.44%, as-fed basis). Diets were formulated to be isocaloric and based on the ideal protein concept. Pigs were housed individually, allowed ad libitum access to feed and water, and slaughtered at 112 kg of BW. The pSTSR affected neither ADG (P = 0.88) nor 10th rib LM area (LMA; P = 0.51), but it decreased (P < 0.01) ADFI, average backfat thickness, 10th rib fat depth, weights of leaf fat and ham fat, improved (P < 0.05) G:F, and increased (P < 0.01) weights of four trimmed lean cuts (T-cuts), and percentages of ham lean and bone. Increasing total Lys increased ADG (quadratic; P < 0.05) and ADFI (linear; P < 0.01). The G:F, plasma urea N concentrations (PUN), and T-cuts were affected by the interaction pSTSR x dietary Lys (P < 0.01). Without pSTSR, the G:F did not differ (P = 0.37) among pigs fed 0.52% and greater total Lys. With pSTSR, the G:F was less (P < 0.05) for pigs fed 0.52% than 0.98 and 1.44% total Lys. Increases in dietary total Lys resulted in increased PUN (P < 0.01), and incremental increases were less in pSTSR-implanted pigs. Maximal yield of T-cuts was at 0.98% dietary total Lys in nonimplanted pigs and 1.21% total Lys in pSTSR-implanted pigs. Estimates of total Lys requirements of pigs without and with pSTSR, respectively, were 0.52 and 0.86% for growth (ADG and G:F) and 0.73 and 0.88% for lean production (LMA and T-cuts). Equivalent apparent ileal digestible Lys requirements of pigs without and with pSTSR, respectively, were 0.44 and 0.68% for growth, and 0.62 and 0.75% for lean production. With ADFI of 3.5 kg daily, an intake of approximately 26.1 g of total daily Lys (0.75%) or 22.4 g of apparent ileal digestible Lys is needed to maximize lean production in finishing barrows receiving 4 mg pST/d via sustained-release implant.

We generated a reference map of the Arabidopsis mature pollen proteome by using multiple protein extraction techniques followed by 2-DE and ESI-MS/MS. We identified 135 distinct proteins from a total of 179 protein spots. We found that half of the identified proteins are involved in metabolism (20%), energy generation (17%), or cell structure (12%); these percentages are similar to those determined for the pollen transcriptome and this similarity is consistent with the idea that in addition to the mRNAs, the mature pollen grain contains proteins necessary for germination and rapid pollen tube growth. We identified ten proteins of unknown function, three of which are flower- or pollen-specific, and we identified nine proteins whose RNAs were absent from the transcriptome, seven of which are involved in metabolism, energy generation, or cell wall structure. Our work complements and extends recent analyses of the pollen transcriptome.

One is based on the detection of SYBR Green bound to PCR products and the second method is more specific, detecting the cleavage of a fluorogenic (TaqMan) probe bound to a target sequence during primer extension phase. Novel primers and probes that amplify small fragments (<80 bp) of the Map specific insertion sequence, IS900 were designed. Both the SYBR Green and TaqMan assays are sensitive, able to detect 4 fg of DNA extracted from Map strain ATCC19698. This amount of DNA corresponds to the detection of 0.8 cells. Map cells were quantified directly from 7H9 broth using the SYBR Green assay and compared to dilutions of DNA extracted from an equivalent number of cells. The SYBR Green assay of 7H9 broth resulted in a minimum detectable limit of 0.07 cells (equivalent to 0.34 fg of DNA). Media ingredients were not observed to interfere with the assay. Since no extraction step was necessary in the direct cell measurements, direct detection was ten-fold more sensitive than detection of extracted DNA. Both SYBR Green and TaqMan assays are highly specific for the detection of Map. They did not detect any closely related members of the avium complex, other species of mycobacteria, or related genera that are likely to be present in environmental samples. No reporter signal was detected during TaqMan assays performed with 100 pg of template DNA from the non-Map organisms.

Expected heterozygosity for 26 isozyme loci, averaged over 10 populations, was 0.121. More notable than the relatively high level of diversity when compared to other woody endemics was the strong decrease in expected heterozygosity with latitude. Differentiation (F sub(ST)) was 0.152, higher than values for many north temperate conifers with larger distributions. The number of migrants per generation (Nm) was 1.34 or 2.70, depending on the method of estimation. Inbreeding appeared low; F sub(IS) was only 0.003, in agreement with multilocus population outcrossing rates (t sub(m)), which were generally well above 0.90. No difference in t sub(m) was found between isolated vs. clustered trees. However, the number of seeds per cone was greatest in the densest populations; t sub(m) is a measure of effective outcrossing after mortality in the embryonic stage, whereas a reduced number of seeds per cone indicates self pollination. Selfing increased after logging; outcrossing rate before logging was 0.961 and after logging, 0.756. Despite Brewer spruce's narrow, fragmented distribution, the outlook for its conservation was good, with the exception of possible negative effects of logging.

Of 4076 oak toads captured, 92.2% were adults. Substantial (n greater than or equal to 30 exiting juveniles) recruitment occurred only three times (once each at three ponds during two years). Males outnumbered females (average for all years 2.3:1). Most captures occurred during May-September. Adult captures during June-August increased with heavier rainfall but were not influenced by the durations of preceding dry periods. Movement patterns of metamorphs suggested that oak toads emigrated when moisture conditions become favorable. Pond use by adults was correlated with maximum change in pond depth (May-September). Juvenile recruitment was negatively correlated with minimum pond depth and the number of weeks since a pond was last dry, and positively correlated with the maximum number of weeks a pond held water continuously. The number of breeding adults and juvenile recruitment were highest at ponds within the hardwood-invaded upland matrix. The direction of most immigrations and emigrations was nonrandom, but movement occurred from all directions, and the mean direction of pond entry and exit did not always correspond. A total of 21.1% of individuals was recaptured; 13.3% of first captures were recaptured during the same year, and 7.7% during a subsequent year. Only 1.9% of captured oak toads moved among ponds, mostly within a distance of 132 m. We did not detect adult population trends over the 10-yr studied. Presence or absence at ponds in any given year was a poor indicator of overall use. We saw little evidence of local extinction or 'rescue,' but were unable to determine whether juveniles returned to natal ponds or colonized new ponds for breeding as adults. Oak toad conservation can best be ensured by maintaining multiple ponds within a landscape to increase the probability of recruitment within the landscape neighborhood during at least some years and at some ponds, and to increase the likelihood of inter-pond movement.

The quantity and quality (i.e., chemistry) of these materials is sensitive to land management practices. Monitoring alterations in the chemistry of water soluble organics resulting from land management practices is difficult because of the complexity and low concentration of these compounds. A procedure is described in which the water soluble organics are quantitatively derivatized with trifluoroacetic anhydride and then analyzed by liquid state proton nuclear magnetic resonance (1H NMR). The procedure was applied to sample amounts as low as 0.03mg from the forest floor and root exudates. The root exudate samples were dominated by aliphatic compounds with relatively few O-alkyl, olefinic and aromatic compounds. The chemistry of the samples originating from the forest floor differed dramatically with soil texture and treatment combinations.

This paper explores and compares the potential consequences of changes in forest cover for fish production in upland, coldwater stream environments in New England, U.S.A. and the British Isles, two regions which share important similarities with respect to overall physical, biotic and socio-economic setting. Both regions were extensively deforested and essentially no extensive old-growth forest stands remain. In New England, recovering forests, consisting almost entirely of naturally-regenerated native species, now cover >60% of the landscape. Associated with this large-scale reforestation, open landscapes, common in the 19th and first half the 20th century, are currently rare and declining in this region. In the British Isles, forests still cover <20% of the landscape, and existing forests largely consist of exotic conifer plantations stocked at high stand densities and harvested at frequent rotations. While forest restoration and conservation is frequently recommended as a fisheries habitat conservation and restoration tool, consideration of the way in which forests affect essential aspects of fish habitat suggests that response of upland stream fish to landscape change is inherently complex. Under certain environmental settings and reforestation practices, conversion of open landscapes to young-mature forests can negatively impact fish production. Further, the effects of re-establishing old-growth forests are difficult to predict for the two regions (due to the current absence of such landscapes), and are likely to depend strongly on the extent to which critical ecosystem attributes (large-scale disturbances, fish migrations, keystone species, large woody debris recruitment) are allowed to be re-established. Understanding these context-dependencies is critical for predicting fish responses, and should help managers set realistic conservation, management and restoration goals. Management may best be served by promoting a diversity of land cover types in a way that emulates natural landscape and disturbance dynamics. This goal presents very different challenges in New England and the British Isles due to differences in current and predicted land use trajectories, along with differences in ecological context and public perception.

The screening method is based on percent insect mortality, average survival time, mortality distribution, percent spore germination, fungal life cycle duration, and spore production on the insect. Based on these parameters, only 11 strains merited further study. The use of a sound scientific protocol for the selection of promising fungal entomopathogens should lead to more efficient use of time, labor, and financial resources in biological control programs.

In a set of experiments comparing sheep red blood cell (SRBC) plates with a chromogenic agar formulation designed by R & F Laboratories, with a spiking dose of 47 plate-enumerated spores in 100 ml tap water, the mean spore recoveries were 34.0 and 30.8 spores, respectively. When a spiking dose of 100 fluorescence activated cell sorter(FACS)-enumerated spores was used in 100 ml potable water, the average recovery with SRBC plates was 48 spores. Detection efforts with spiking doses of 35 and 10 spores in 1 L tap water were successful, but recovery efforts from spiked 1 L volumes of source water were problematic due to the concomitant growth of normal spore-forming flora. Recoveries were also attempted on 10 L volumes of tap water. For a spiking dose of 100 spores, mean recovery from six replicates was 11 spores (+/-6.8, range 2-20), and for a spiking dose of 10 spores, mean recovery from six replicates was 2.3 spores (+/-3.5, range 0-9). Efforts were also made to "direct detect" spores via polymerase chain reaction (PCR) on washes from filters. When spiking 534 spores in 100 ml, 9/9 replicates of spiked tap water, 6/6 source water replicates, and 0/3 unspiked controls were positive by lef PCR. When 534 spores were spiked into 1 L tap water, the lef PCR was unsuccessful; however, using the nested vrrA PCR resulted in 4/9 spiked samples, and 0/3 unspiked controls, testing positive. Our results indicate that an inexpensive and user-friendly method, utilizing filtration apparatus commonly present in many water quality testing labs, can readily be adapted for use in detecting this potential threat agent.

Cultivar-rotation studies were conducted in three fields to assess how different levels and types of resistance affected the race structure and population dynamics of the pathogen when deployed in fields initially containing single or mixed races of the pathogen. In a field with both races present, a high level of partial resistance in cv. K 346 was most effective in reducing disease and decreasing the proportion of race 1 in the pathogen population. The deployment of complete resistance in cv. NC 71 resulted in intermediate levels of disease control and race 1 became the predominate race. The cv. K 326, with a low level of partial resistance, had the highest levels of disease, and race 0 was the dominant race recovered. In a field where no race 1 was detected initially, disease incidence was high with the use of partial resistance. Complete resistance was very effective in suppressing disease, but race 1 was recovered after only one growing season. By the end of the third growing season, race 1 was recovered from most treatments where single-gene resistance was deployed. A high level of partial resistance was most effective in suppressing disease in a field where race 1 initially was the predominant race. A rotation between cultivars with single-gene resistance and cultivars with a high level of partial resistance should provide the most effective approach to black shank management. This rotation will reduce disease incidence and minimize race shifts in the pathogen and, over time, should prolong the usefulness of the Ph gene for black shank control in commercial production of tobacco.

Technology tools can be as basic as identifying naturally occurring strains with deletions that support differentiating infected from vaccinated animal (DIVA) needs or be based on higher technology developments such as improved protein expression and purification methods, transgenic plant- and plant virus-based antigen production, and novel adjuvants that target specific immune responses. These new approaches, when applied to the development of marker vaccines and companion diagnostic test kits hold tremendous potential for developing improved tools for eradication and control programs. Marker vaccines and companion diagnostic test kits must meet the established licensing requirements for purity, potency, safety and efficacy. Efficacy claims are based on evaluation of the level of protection demonstrated in host animal trials and may range from ''prevents infection with (a specific agent)'', to ''for use as an aid in the reduction of disease due to (a specific agent).'' The differences in claims and recommendations are a function of the variation in protection elicited by various vaccines. For designing effective eradication programs, vaccine efficacy characteristics such as for reducing susceptibility to infections and spread of infections must be well defined; similarly, diagnostic test performance characteristics (efficacy) must be determined. In addition to data to support efficacy claims, it is imperative that safety of production and use of vaccines be evaluated. During the design of marker vaccines and diagnostic tests, it is important to consider the application of appropriate technologies to improve the safety of these products. Use of recombinant technologies for production of vaccines and/or diagnostic test antigens can reduce the biosafety concerns during production and during use, including human exposure to zoonotic pathogens during production and use, and potential spread of foreign animal disease agents due to loss of biocontainment. In addition, vaccines may induce adverse reactions. It is important to determine the frequency of adverse events and to reduce the likelihood of induction of adverse reactions through proper design.

Previous studies have demonstrated the capability of the model to simulate runoff and sediment, but not phosphorus (P). The main purpose of this article is to evaluate the performance of AnnAGNPS on P simulation using comparisons with measurements from the Deep Hollow watershed of the Mississippi Delta Management Systems Evaluation Area (MDMSEA) project. A sensitivity analysis was performed to identify input parameters whose impact is the greatest on P yields. Sensitivity analysis results indicate that the most sensitive variables of those selected are initial soil P contents, P application rate, and plant P uptake. AnnAGNPS simulations of dissolved P yield do not agree well with observed dissolved P yield (Nash-Sutcliffe coefficient of efficiency of 0.34, R super(2) of 0.51, and slope of 0.24); however, AnnAGNPS simulations of total P yield agree well with observed total P yield (Nash-Sutcliffe coefficient of efficiency of 0.85, R super(2) of 0.88, and slope of 0.83). The difference in dissolved P yield may be attributed to limitations in model simulation of P processes. Uncertainties in input parameter selections also affect the model's performance.

The United States Department of Agriculture played a key role in delivery of that success by developing biologics policy, evaluating each product, and ensuring that the conditions of licensure were met. What was most critical in the overall eradication effort, however, was the detailed and dedicated interaction among key players: the biologics regulators, manufacturers, Federal, State, and local regulatory partners, veterinary researchers, industry associations, and animal owners. A good disease control program has to include all of these. The regulatory requirements for licensure of marker vaccines and diagnostic test kits are not different from that for other products. There are several mechanisms for vaccine approval, some more rapid than others, but only a few that could apply to these products. Generally, the platforms that might support marker vaccines and companion diagnostic kits are those based on genetic engineering or protein manipulation. If the product is derived from the application of biotechnology, then additional regulatory considerations are applicable. Most important of these are the considerations found in the National Environmental Policy Act (NEPA), wherein deliberate release of any organism containing recombinant DNA into the environment is subject to review and approval by appropriate federal agencies. Environmental release and NEPA compliance are discussed.

We tested the hypothesis that differences in infiltration are due to changes in soil structure related to treatment-induced biological changes. All plots received the same tillage (plow and summer rod-weeding). Manure (containing 111 kg N ha super(-1)), pea (Pisum sativum L.), vine (containing 34 kg N ha super(-1)), or N additions of 0, 45 and 90 kg ha super(-1) were treatment variables with burning of residue as an additional factor within N-treatments. We measured soil organic C and N, water stability of whole soil, water stable aggregates, percolation through soil columns, glomalin, soil-aggregating basidiomycetes, earthworm populations, and dry sieve aggregate fractions. Infiltration was correlated (r = 0.67-0.95) to C, N, stability of whole soil, percolation, and glomalin. Basidiomycete extracellular carbohydrate assay values and earthworm populations did not follow soil C concentration, but appeared to be more sensitive to residue burning and to the addition of pea vine residue and manure. Dry sieve fractions were not well correlated to the other variables. Burning reduced (p < 0.05) water stability of whole soil, total glomalin, basidiomycetes, and earthworm counts. It also reduced dry aggregates of 0.5-2.0 mm size, but neither burning nor N fertilizer affected total C or total N or ponded infiltration rate. Water stability of whole soil and of 1-2-mm aggregates was greater at 45 kg N ha super(-1) than in the 0 and 90 kg N ha super(-1) treatments. Zero N fertilizer produced significantly greater 0.5-2.0 mm dry aggregate fractions. We conclude that differences in infiltration measured in the field are related to relatively small differences in aggregate stability, but not closely related to N or residue burning treatments. The lack of an effect of N fertilizer or residue burning on total C and N, along with the excellent correlation between glomalin and total C (r = 0.99) and total N (r = 0.98), indicates that the major pool of soil carbon may be dependent on arbuscular mycorrhizal fungi.

AN - 19772638; 6886746 AB - Anaphesiole Girault (Hymenoptera: Mymaridae) is a solitary egg parasitoid of Lygus bugs (Heteroptera: Miridae) in North America. Circumstantial evidence suggests that A. iole females are strictly proovigenic. This study was designed to determine if honey-fed A. iole females could in fact mature additional eggs if exposed to hosts for a few days then removed from hosts and held at 25 degree C for 0, 3, or 6 days. Contrary to expectation, honey-fed A. iole females matured considerably more eggs when deprived of hosts for 3 or 6 days rather than 0 days. This research suggests that A. iole females are not strictly proovigenic. However, they do have proovigenic tendencies, since most females emerge with at least 71% of their potential fecundity.

Percent of the coterminous United States classified as urban increased from 2.5% in 1990 to 3.1% in 2000, an area about the size of Vermont and New Hampshire combined. Patterns of urban expansion reveal that increased growth rates are likely in the future. The most urbanized regions of the United States are the Northeast (9.7%) and the Southeast (7.5%), with these regions also exhibiting the greatest increase in percent urban land between 1990 and 2000. Forests near urban communities face a special set of challenges that will only intensify as these communities grow in area, population, and complexity.

Measuring benefits that accrue from the community forest is the first step to altering forest structure in ways that will enhance future benefits. This article describes the structure, function, and value of street and park tree populations in Fort Collins, Colorado; Cheyenne, Wyoming; Bismarck, North Dakota; Berkeley, California; and Glendale, Arizona. Although these cities spent $13-65 annually per tree, benefits ranged from $31 to $89 per tree. For every dollar invested in management, benefits returned annually ranged from $1.37 to $3.09. Strategies each city can take to increase net benefits are presented.

By 2050, four states (Rhode Island, New Jersey, Massachusetts, and Connecticut) are projected to be more than one-half urban land. The total projected amount of US forestland estimated to be subsumed by urbanization between 2000 and 2050 is about 118,300 km super(2), an area approximately the size of Pennsylvania. Because of this urban growth, more regional planning and management may be needed to sustain forest products and ecosystem services required by a growing urban population.

Determination of temporal expression levels of the genes that control muscle development is an important step in molecular analysis. Real-time quantitative reverse transcriptase polymerase chain reaction was used to characterize expression in the muscle of 3 MRF, 2 MEF, and 2 myostatin genes during 9 stages of trout development. Expression of genes that promote muscle growth (MRF and MEF) peaked in swim-up fry, and in some cases again in 25-g, 140-g, and spawning fish. Myostatin genes, which restrict muscle growth, were expressed at very low levels early in development, but their expression levels were elevated in 140-g and spawning fish. Expression levels and the known function of each tested gene were used to infer the extent of hyperplasia, hypertrophy, and restriction of muscle growth during each stage. Both hyperplasia and hypertrophy appeared to peak in swim-up fry and spawning females, and hyperplasia also appeared to peak in 25-g fish. These results should provide valuable information for developmental biologists and those interested in understanding muscle growth in fish.

The simultaneous corn and cover crop system was developed by U.S. Department of Agriculture's Natural Resources Conservation Service (USDA-NRCS) for dairy farms in the northeastern United States, where short growing seasons have limited fall seeding of cover crops. The simultaneous corn and cover crop system uses post-emergence imidazolinone herbicides to allow for simultaneous seeding of cover crops with silage corn. Trials were established at two locations in the Cannonsville Reservoir watershed, New York, part of New York City's drinking water supply system, to assess the effects of this cover cropping system on water quality. Rain simulations (60 mm hr super(-1)) were conducted to evaluate the initial 30 minutes of runoff from small (1 x 2 m; 3 ft x 7 ft) plots before and after surface application of dairy manure (50 or 100 kg total P ha super(-1); 45 or 89 Ib P ac super(-1)). Corn yields from plots interseeded with red clover compared most favorably with the conventionally cropped controls, with no significant differences in yields noted between the two treatments at either location. Prior to dairy manure application, losses of P in runoff were primarily a function of erosion. Because all cover crops increased ground cover (up to 81 percent greater than the control), total P loads in runoff were significantly lower from cover cropped plots (averaging 10 mg per plot) than from conventionally cropped controls (averaging 39 mg per plot). At the same time, suspended solids loads averaged 25.3 g (1 oz) from the control plots and 5.9 g (0.2 oz) from the cover crop plots. Despite concern that release of soluble P from the cover crops could enrich dissolved reactive P in runoff, dissolved reactive P losses from the simultaneous corn and cover crop system were generally not different from conventionally-cropped silage corn losses. Application of manure obscured cover crop/conventional silage corn treatment differences with regard to P runoff, with dissolved reactive P becoming the dominant form of P in runoff due to contributions of readily soluble P in manure. Because runoff P losses were already high from unmanured conventional silage corn plots, application of manure did not significantly increase P losses from some of the conventional silage corn treatments. Results highlight the agronomic and water quality benefits of the simultaneous corn and cover crop system, particularly when implemented with red clover.

Kent L. Merr., plants susceptible to the soybean cyst nematode (SCN), Heterodera glycines Ichinohe, were inoculated and allowed to develop feeding sites (syncytia) for 8 days. Root samples enriched in syncytial cells were collected using laser capture microdissection (LCM). RNA was extracted and used to make a cDNA library and expressed sequence tags (ESTs) were produced and used for a Gene Ontology (GO) analysis. RT-PCR results indicated enhanced expression of an aquaporin (GmPIP2,2), alpha -tubulin (GmTubA1), beta -tubulin (GmTubB4) and several other genes in syncytium-enriched samples as compared to samples extracted from whole roots. While RT-PCR data showed increased transcript levels of GmPIP2,2 from LCM tissue enriched in syncytial cells, in situ hybridization showed prominent GmPIP2,2 hybridization to RNA in the parenchymal cells tightly juxtaposed to the syncytium. Immunolocalization indicated stronger alpha -tubulin signal within the syncytium as compared to surrounding tissue. However, alpha -tubulin labeling appeared diffuse or clumped. Thus, LCM allowed for the isolation of tissue enriched for syncytial cells, providing material suitable for a variety of molecular analyses.

Yet, no standard, protocol, or method is available for guiding the selection of a water quality sampling strategy for runoff from fields and small watersheds. The objective of this study was to develop a methodology that provides guidance in the selection of a water quality sampling strategy for headwater streams (drainage areas less than 2500 ha; 6,177 ac). The developed method is based on the dimensionless unit hydrograph and relationships of measured pollutant concentrations to discharge hydrographs. The methodology was designed for storm events with a specific return interval and a selected acceptable level of error in pollutant load. Nine input parameters (hydraulic length, watershed slope, curve number, drainage area, runoff coefficient, 10-year, one hour precipitation amount, 100-year, one hour precipitation amount, 10 year, 24 hour precipitation amount, and recurrence interval) were used to develop the design hydrograph. Both time- and flow-paced sampling techniques were considered. A global sensitivity analysis of the method indicated that time-paced sampling was primarily sensitive to parameters included in the time of concentration calculation (hydraulic length, watershed slope, and curve number). Flow-paced sampling showed some sensitivity to all nine input parameters. An example application illustrates the utility of the method. Use of the method should facilitate the selection of water quality sampling strategies for field and small watershed scale studies and aid in budgetary planning for sample collection and analysis. The measurements taken based on the recommended sampling strategy will provide more confidence in the pollutant storm load estimates.

Our goal was to evaluate the use of geographic information systems (GIS), global positioning systems (GPS), modeling and remote sensing for reducing residual soil NO sub(3)-N and NO sub(3)-N leaching in a center-pivot irrigated corn (Zea mays L.) field. Specific objectives were: 1) to determine if productivity zones delineated using precision agriculture technologies could also correctly identify unique areas within corn fields that differed in residual soil NO sub(3)-N and NO sub(3)-N leaching potential; and 2) evaluate the potential to use remote sensing of crop productivity to reduce NO sub(3)-N leaching losses. This study was conducted in northeastern Colorado during the 2000 and 2001 growing seasons in a 70 ha (173 ac) center-pivot irrigated commercial cornfield. For the first objective, initial and final soil samples after harvesting were collected at known locations in high, medium and low productivity areas across this field. For the second objective initial and final soil samples after harvesting were collected in a low productivity area where "in season" N management was conducted based on remote sensing data. Crop yields and total N were determined on plant samples located at the soil sampling coordinates. The N reflectance index was used to determine the "in season" N application. Remote-sensing-based N fertilization treatment occurred whenever the mean N reflectance index was lower than 0.95 and/or more than 50 percent of the area had an N reflectance index less than 0.95. For both studies, the nitrate leaching economic analysis package and GIS were used to evaluate NO sub(3)-N leaching losses. We found that GIS, GPS, and modeling technologies can be used to identify and simulate the spatial residual soil NO sub(3)-N patterns. Productivity zones delineated using precision agriculture technologies identified areas within corn production fields that differed in residual soil NO sub(3)-N and NO sub(3)-N leaching potential. This spatial variability was negatively correlated with the soil texture (P<0.001), having lower residual soil NO sub(3)-N on the lower productivity sandier areas, which also had a higher NO sub(3)-N leaching potential. The N Reflectance Index method can maximize the synchronization of "in season" N applications with corn N uptake needs to increase N use efficiencies and reduce NO sub(3)-N leaching losses by 47 percent when compared to traditional practices (P<0.0001).

Previous studies of coastal Douglas fir (Pseudotsuga menziesii var. menziesii) have been inconclusive with respect to geographical patterns of variation, due in part to limited sample intensity and geographical and climatic representation. This study describes and maps patterns of genetic variation in adaptive traits in coastal Douglas fir in western Oregon and Washington, USA. times METHODS: Traits of growth, phenology and partitioning were measured in seedlings of 1338 parents from 1048 locations grown in common gardens. Relations between traits and environments of seed sources were explored using regressions and canonical correlation analysis. Maps of genetic variation as related to the environment were developed using a geographical information system (GIS). times Key Results Populations differed considerably for adaptive traits, in particular for bud phenology and emergence. Variation in bud-set, emergence and growth was strongly related to elevation and cool-season temperatures. Variation in bud-burst and partitioning to stem diameter versus height was related to latitude and summer drought. Seedlings from the east side of the Washington Cascades were considerably smaller, set bud later and burst bud earlier than populations from the west side. times CONCLUSIONS: Winter temperatures and frost dates are of overriding importance to the adaptation of Douglas fir to Pacific Northwest environments. Summer drought is of less importance. Maps generated using canonical correlation analysis and GIS allow easy visualization of a complex array of traits as related to a complex array of environments. The composite traits derived from canonical correlation analysis show two different patterns of variation associated with different gradients of cool-season temperatures and summer drought. The difference in growth and phenology between the westside and eastside Washington Cascades is hypothesized to be a consequence of the presence of interior variety (P. menziessii var. glauca) on the eastside.

The parasitoid lays its egg on the leaf underneath the host nymph. First instars hatch and later penetrate the whitefly. Previous studies have shown that the initiation of parasitoid penetration induces the host to form a cellular capsule around the parasitoid. As described here, females never oviposited once the 4 super(th) instar whitefly nymph had initiated adult development. First instar E. mundus larvae were observed under 2 super(nd), 3 super(rd) and 4 super(th) instar whitefly nymphs, however, penetration did not occur until the whitefly had reached the 4 super(th) instar. The non-penetrating E. mundus larva almost always induced permanent developmental arrest in its 4 super(th) instar whitefly host and also caused a reduction in whole body host ecdysteroid titers. Therefore, unless there is a peak in molting hormone titer in the area local to penetration, it appears that the induction of capsule formation is not due to an increase in ecdysteroid titer. As the capsule formed around the penetrating parasitoid, host epidermal cells multiplied and became cuboidal and columnar, and relatively thick layers of new cuticle were deposited within the developing capsule, particularly near its ventral opening. The newly formed host cuticle was thinner in the dorsal part of the capsule and appeared to be absent at its apex. These results provide new information regarding the timing and dynamics of parasitoid oviposition and egg hatch as related to larval penetration, parasitoid-induced changes in whitefly development, molting hormone titers and the process of capsule formation.

Bioassays were conducted in a modified Y-tube olfactometer, where incoming air was filtered and humidified before passing through chambers that held plant/conspecific treatments. A LED, placed behind an organdy screen at the end of one arm of the Y-tube, simulated a visual plant cue. In agreement with our previous findings, fifth-instar and adult female L. hesperus were attracted to plant/conspecific odor combinations, but adult males were not. Independently, the LED also was attractive to immature and adult female L. hesperus, and for all life stages, a much larger percentage of the bugs walked to the extreme end of the Y-tube when the visual cue was present. When visual and volatile cues were presented simultaneously, responses by both immature and adult (male and female) L. hesperus were significantly enhanced. Plant/conspecific treatments that had been marginally acceptable when only volatile stimuli were available showed the greatest enhancement in response with the addition of the visual cue. Presentation of visual and volatile cues together led to a mean increase in the percentage of bugs that walked to the extreme end of the Y-tube (nymphs, 36.6%; females, 23.4%; males, 26.1%). Results are discussed in terms of stage-specific responses and how these behavioral differences will likely play a role in developing effective trapping and monitoring systems for this important pest.

This leafhopper was recently identified in the Columbia Basin of Washington and Oregon as the probable vector of the beet leafhopper-transmitted virescence agent phytoplasma, causal agent of several vegetable crop diseases, including potato purple top. Plants selected for study were sugar beet, Beta vulgaris L.; radish, Raphanus sativus L.; dry bean, Phaseolus vulgaris L.; potato, Solanum tuberosum L.; carrot, Daucus carota L.; and tomato, Lycopersicon esculentum Mill. Leafhopper adults were confined on caged plants, and settling behavior was observed during a 72-h period and survival was monitored for 40 d. Also, oviposition and nymphal production were investigated by maintaining leafhoppers for approximately 90 d on each of the selected plants. Sixty to 100% of leafhoppers settled on all studied plants during the first 5 h, but settling on bean and tomato declined sharply thereafter. Leafhopper mortality was very high on bean and tomato, with 95 and 65% of the leafhoppers, respectively, dying in about a week. In contrast, 77, 90, and 95% of leafhoppers maintained on potato, sugar beet, and radish, respectively, survived until the end of the 40-d experimental period. Beet leafhopper oviposition and nymphal production and development only occurred on sugar beet, radish, and potato; reproduction was lower on potato.

This "exurban" development ( similar to 6-25 homes/km super(2)) includes urban fringe development (UFD) on the periphery of cities and rural residential development (RRD) in rural areas attractive in natural amenities. This paper synthesizes current knowledge on the effects of UFD and RRD. We present two case studies and examine the patterns of biodiversity response and the ecological mechanisms that may underlie these responses. We found that many native species have reduced survival and reproduction near homes, and native species richness often drops with increased exurban densities. Exotic species, some human-adapted native species, and species from early successional stages often increase with exurban development. These relationships are sometimes nonlinear, with sharp thresholds in biodiversity response. These effects may be manifest for several decades following exurban development, so that biodiversity is likely still responding to the wave of exurban expansion that has occurred since 1950. The location of exurban development is often nonrandom relative to biodiversity because both are influenced by biophysical factors. Consequently, the effects on biodiversity may be disproportionately large relative to the area of exurban development. RRD is more likely than UFD to occur near public lands; hence it may have a larger influence on nature reserves and wilderness species. The ecological mechanisms that may underlie these responses involve alteration of habitat, ecological processes, biotic interactions, and increased human disturbance. Research on the patterns and mechanisms of biodiversity remains underdeveloped, and comparative and experimental studies are needed. Knowledge resulting from such studies will increase our ability to understand, manage, and mitigate negative impacts on biodiversity.

Merr.] fields were used in determining the local and regional (effective) surface roughness length zo and , respectively. For corn, canopy height increased from similar to 1 to 2 m and the leaf area index changed from similar to 1 to 4 during the study period, while for soybean, canopy height increased from similar to 0.1 to 0.5 m and the leaf area index increased from similar to 0.5 to 2. A procedure for the aggregation of local roughness values from the different land cover types based on blending-height concepts yielded effective surface roughness values that were from similar to 1/2 to 1/4 of the magnitude estimated with the aircraft data. This indicated additional kinematic stress caused by form drag from isolated obstacles (i.e., trees, houses, and farm buildings), and the interaction of adjacent corn- and soybean fields were probably important factors influencing the effective surface roughness length for this landscape. The comparison of u* measurements from the towers versus the aircraft indicated that u* from aircraft was 20%-30% higher, on average, and that u* over corn was 10%-30% higher than over soybean, depending on stability. These results provide further evidence for the likely sources of additional kinematic stress. Although there was an increase in zo and over time as the crops rapidly developed, particularly for corn, there was a more significant trend of increasing roughness length with decreasing wind speed at wind speed thresholds of around 5 m s-1 for the aircraft and 3 m s-1 for the tower measurements. Other studies have recently reported such a trend. The impact on computed sensible heat flux H using derived from the aggregation of zo from the different land cover types, using the blending-height scheme, and that estimated from the aircraft observations, was evaluated using a calibrated single-source/bulk resistance approach with surface-air temperature differences from the aircraft observations. An underestimate of by 50% and 75% resulted in a bias in the H estimates of approximately 10% and 15%, respectively. This is a relatively minor error when considering that the root-mean-square error (rmse) value between single-source estimates and the aircraft observations of H was 15 W m-2 using the aircraft-derived , and only increased to approximately 20 and 25 W m-2 using the 1/2 and 1/4 values, as estimated from the blending-height scheme. The magnitude of the excess resistance relative to the aerodynamic resistance to heat transfer was a major contributing factor in minimizing the error in heat flux calculations resulting from these underestimations of .

Soil moisture retrieval was performed using a dual-polarization 19.4-GHz data algorithm that requires the specification of two vegetation parameters-single scattering albedo and vegetation water content. Single scattering albedo was estimated using published values. A method for estimating the vegetation water content from the microwave polarization index using SSM/I 37.0-GHz data was developed for the region using extensive datasets developed as part of SMEX02. Analyses indicated that the sensitivity of the brightness temperature to soil moisture decreased as vegetation water content increased. However, there was evidence that SSM/I brightness temperatures changed in response to soil moisture increases resulting from rainfall during the later stages of crop growth. This was partly attributed to the lower soil and vegetation thermal temperatures that typically followed a rainfall. Comparisons between experimentally measured volumetric soil moisture and SSM/I-retrieved soil moisture indicated that soil moisture retrieval was feasible using SSM/I data, but the accuracy highly depended upon the levels of vegetation and atmospheric precipitable water; the standard error of estimate over the 3-week study period was 5.49%. The potential for using this approach on a larger scale was demonstrated by mapping the state of Iowa. Results of this investigation provide new insights on how one might operationally correct for vegetation effects using high-frequency microwave observations.

Mortality at 2 wk postinfection (PI) ranged from 25% for low challenge to 100% for high challenge (P = 0.0001). Gross and histopathological lesions were observed in heart, liver, spleen, lung, and bursa of Fabricius of mortalities at 4 days PI. Listeria monocytogenes challenge resulted in significantly decreased relative weight of the bursa of Fabricius and increased relative weight of the spleen, and L. monocytogenes was isolated by direct plating of liver, pericardium, brain, and both left and right stifle joint synovium (knee) cultures, as well as gall bladder, yolk sac, and cecal tonsil from transfer swabs onto Listeria-selective agar. Isolates were confirmed as positive using Gram stain, biochemical tests, and the Biolog system. High challenge resulted in confirmed L. monocytogenes isolation from 48% of left knee and 59% of right knee cultures. Low challenge resulted in isolation of L. monocytogenes from 11% of both left and right knee cultures. These results suggest that L. monocytogenes Scott A colonization of turkey knee synovial tissue can initiate in day-of-age poults and that L. monocytogenes Scott A can be invasive through air sac infection.Original Abstract: Infeccion respiratoria con Listeria monocytogenes Scott A en pavos.Se estudio la patogenesis de la cepa Scott A de Listeria monocytogenes, mediante el desafio por inoculacion en el saco aereo de pavipollos machos de un dia de edad con desafios bajos (10 super(4), 10 super(5), y 10 super(6) unidades formadoras de colonias -ufc-) o desafios altos (10 super(7) y 10 super(8) ufc) de la cepa de L. monocytogenes Scott A, serotipo 4b. La mortalidad dos semanas despues del desafio vario entre el 25% para el desafio bajo y el 100% para el desafio alto (P < 0.0001). En las aves muertas 4 dias post infeccion, se observaron lesiones macroscopicas e histopatologicas en corazon, higado, bazo y bolsa de Fabricio. El desafio con L. monocytogenes resulto en una disminucion significativa del peso relativo de la bolsa de Fabricio y en un aumento del peso relativo del bazo. Se aislo L. monocytogenes por siembra directa del higado, pericardio, cerebro y del cultivo de liquido sinovial de ambas articulaciones de la rodilla, asi como de hisopos de vesicula biliar, saco vitelino y tonsilas cecales transferidos directamente a agar selectivo para Listeria. Los aislamientos fueron confirmados como positivos utilizando tincion de Gram, pruebas bioquimicas y el sistema Biolog. El desafio alto resulto en el aislamiento de L. monocytogenes en el 48% de cultivos de la rodilla izquierda y en el 59% de los cultivos de la rodilla derecha. El desafio bajo resulto en el aislamiento de L. monocytogenes en el 11% de los cultivos de ambas rodillas. Estos resultados sugieren que la colonizacion por L. monocytogenes del tejido sinovial en pavos puede iniciarse en pavipollos de un dia de edad y que la L. monocytogenes cepa Scott A puede ser invasiva a partir de la infeccion del saco aereo.

Those results prompted further evaluation to determine if inoculation route influenced the prevalence or level of Campylobacter contamination of semen, the digestive tract, or reproductive organs. Individually caged roosters, confirmed to be feces and semen negative for Campylobacter, were challenged with a marker strain of Campylobacter jejuni either orally using 1.0 ml of a diluted cell suspension (log sub(10)4.3 to 6.0 cells), by dropping 0.1 ml of suspension (log sub(10)5.3 to 7.0 cells) on the everted phallus immediately after semen collection or by dip coating an ultrasound probe in the diluted cell suspension (log sub(10)4.3 to 6.0 cells) and then inserting the probe through the vent into the colon. Six days postinoculation, individual feces and semen samples were again collected and cultured for Campylobacter. Seven days postinoculation, roosters were killed, the abdomen aseptically opened to expose the viscera, and one cecum, one testis, and both ductus deferens were collected. The samples were then suspended 1 : 3 (weight/volume) in Bolton enrichment broth for the culture of Campylobacter. Samples were also directly plated onto Cefex agar to enumerate Campylobacter. Campylobacter was recovered 6 days after challenge from feces in 82% of samples (log sub(10)4.1 colony-forming units [CFU]/g sample), 85% of semen samples (log sub(10)2.9 CFU/ml), and on the seventh day postchallenge from 88% of cecal samples (log sub(10)5.8 CFU/g sample). Campylobacter was not directly isolated from any testis sample but was detected following enrichment from 9% (3/33) of ductus deferens samples. Roosters challenged with Campylobacter orally, on the phallus, or by insertion of a Campylobacter dip-coated ultrasound probe were all readily colonized in the ceca and produced Campylobacter-positive semen and feces on day 6 after challenge. The low prevalence of recovery of Campylobacter from the ductus deferens samples and failure to recover from any testis sample suggests that semen may become Campylobacter positive while traversing the cloaca upon the everted phallus. The production of Campylobacter-positive semen could provide a route in addition to fecal-oral for the horizontal transmission of Campylobacter from the rooster to the reproductive tract of the hen.Original Abstract: Nota de Investigacion-Aislamiento de Campylobacter jejuni en heces y semen de gallos reproductores de engorde criados en jaula, inoculados por tres rutas.Con anterioridad se reporto el aislamiento de Campylobacter de los conductos deferentes de 5 de 101 reproductores de engorde (colonizacion natural) y cuatro de esos cinco gallos positivos produjeron con anterioridad muestras de semen positivas a Campylobacter. Estos resultados estimularon la realizacion de estudios adicionales con la finalidad de determinar si la ruta de inoculacion influencio la prevalencia o el nivel de contaminacion con Campylobacter del semen, tracto digestivo u organos reproductivos. Gallos ubicados individualmente en jaulas, confirmados negativos para Campylobacter en heces y semen, fueron desafiados con una cepa estandar de Campylobacter jejuni, bien por via oral utilizando 1 ml de una suspension diluida de celulas (log sub(10)4.3 a 6.0), o colocando sobre el falo expuesto 0.1 ml de suspension (log sub(10)5.3 a 7.0) inmediatamente despues de la recoleccion de semen, o sumergiendo una sonda de ultrasonido en la suspension celular diluida (log sub(10)4.3 a 6.0) para posteriormente introducir la sonda hasta el colon a traves de la abertura de la cloaca. Seis dias posteriores a la inoculacion se tomaron muestras individuales de heces y semen para el cultivo y aislamiento de Campylobacter. Siete dias posteriores a la inoculacion los gallos fueron sacrificados, se disecto asepticamente el abdomen para exponer las visceras y se tomaron un ciego, un testiculo y ambos conductos deferentes. Las muestras fueron resuspendidas en proporcion de 1:3 (peso/volumen) en medio de enriquecimiento Bolton para el cultivo de Campylobacter. A su vez, las muestras fueron sembradas directamente en agar Cefax para cuantificar Campylobacter. Seis dias posteriores al desafio, se aislo Campylobacter en el 82% de las muestras de heces (log sub(10)4.1 CFU/g muestra), del 85% de las muestras de semen (log sub(10)2.9 CFU/g muestra) y en el septimo dia posterior al desafio se aislo del 88% de las muestras de ciego (log sub(10)5.8 CFU/g muestra). No se aislo Campylobacter directamente de ninguna muestra de testiculo, pero despues del enriquecimiento, se detecto en el 9% (3/33) de las muestras de conducto deferente. Los gallos desafiados con Campylobacter bien por via oral, sobre el falo o mediante la insercion de la sonda de ultrasonido en el colon, fueron rapidamente colonizados en el ciego y produjeron heces y semen positivo a Campylobacter seis dias posteriores al desafio. La baja tasa de aislamiento de Campylobacter de las muestras de conducto deferente y el aislamiento negativo de las muestras de testiculo, sugieren que el semen debe volverse positivo a Campylobacter cuando atraviesa la cloaca hacia el falo. La produccion de semen positivo a Campylobacter puede proporcionar una ruta adicional a la oro-fecal para la trasmision horizontal de Campylobacter del gallo al tracto reproductivo de la gallina.

Immunomagnetic beads (IMBs) precoated with anti-E. coli O157:H7 antibody were used to capture and concentrate E. coli O157:H7 present in ground beef. Streptavidin-coated fluorescent beads with anti-E. coli O157:H7 to form immunofluorescent beads (IFBs) were used to detect the E. coli O157:H7 captured by the IMBs by forming IMB sub(M)-E. coli O157:H7 sub(N)-IFB sub(O) sandwich complexes, where the subscripts M, N and O were variable but integral numbers. This sandwich technique was able to detect 500 cfu of the bacteria in a 0.5-mL sample taken from a quantified and diluted broth culture. The method was then applied to detect E. coli O157:H7 in artificially contaminated ground beef. Known quantities of freshly cultured E. coli O157:H7 cells were added to 25-g ground beef patties held in sterile bags with filters. The inoculated patties were stored at 7C overnight; 75 mL of E. coli broth was added to each sample, and the bags were incubated at 40C with shaking at 160 rpm for 4.5 h. After the enrichment, E. coli O157:H7 in the filtrate was captured and concentrated with IMBs and further conjugated with IFBs for detection. The results demonstrate that, after a 4.5-h enrichment period, the developed procedure can detect the presence of E. coli O157:H7 in ground beef previously spiked with 1 cfu-g.

Merr.] canopies was established as part of the Soil Moisture-Atmosphere Coupling Experiment (SMACEX) in central Iowa during the summer of 2002 to measure fluxes of heat, water vapor, and carbon dioxide (CO2) during the growing season. Additionally, EC measurements of water vapor and CO2 fluxes from an aircraft platform complemented the tower-based measurements. Sensible heat, water vapor, and CO2 fluxes showed the greatest spatial and temporal variability during the early crop growth stage. Differences in all of the energy balance components were detectable between corn and soybean as well as within similar crops throughout the study period. Tower network-averaged fluxes of sensible heat, water vapor, and CO2 were observed to be in good agreement with area-averaged aircraft flux measurements.

The primary objective of SMEX02 was the validation of microwave soil moisture retrieval algorithms for existing and new prototype satellite microwave sensor systems under rapidly changing crop biomass conditions. The SMACEX study was designed to provide direct measurement/remote sensing/modeling approaches for understanding the impact of spatial and temporal variability in vegetation cover, soil moisture, and other land surface states on turbulent flux exchange with the atmosphere. The unique dataset consisting of in situ and aircraft measurements of atmospheric, vegetation, and soil properties and fluxes allows for a detailed and rigorous analysis, and the validation of surface states and fluxes being diagnosed using remote sensing methods at various scales. Research results presented in this special issue have illuminated the potential of satellite remote sensing algorithms for soil moisture retrieval, land surface flux estimation, and the assimilation of surface states and diagnostically modeled fluxes into prognostic land surface models. Ground- and aircraft-based remote sensing of the land surface and atmospheric boundary layer properties are used to quantify heat fluxes at the tower footprint and regional scales. Tower- and aircraft-based heat and momentum fluxes are used to evaluate local and regional roughness. The spatial and temporal variations in water, energy, and carbon fluxes from the tower network and aircraft under changing vegetation cover and soil moisture conditions are evaluated. An overview of the experimental site, design, data, hydrometeorological conditions, and results is presented in this introduction, and serves as a preface to this special issue highlighting the SMACEX results.

The disease is highly contagious and FMD virus (FMDV) replicates and spreads extremely rapidly. Outbreaks in previously FMD-free countries, including Taiwan, the United Kingdom, and Uruguay, and the potential use of FMDV by terrorist groups have demonstrated the vulnerability of countries and the need to develop control strategies that can rapidly inhibit or limit disease spread. The current vaccine, an inactivated whole virus preparation, has a number of limitations for use in outbreaks in disease-free countries. We have developed an alternative approach using a genetically engineered FMD subunit vaccine that only contains the portions of the viral genome required for virus capsid assembly and lacks the coding region for most of the viral nonstructural (NS) proteins including the highly immunogenic 3D protein. Thus, animals inoculated with this marker vaccine can readily be differentiated from infected animals using diagnostic assays employing the NS proteins not present in the vaccine and production of this vaccine, which does not contain infectious FMDV, does not require expensive high-containment manufacturing facilities. One inoculation of this subunit vaccine delivered in a replication-defective human adenovirus vector can induce rapid, within 7 days, and relatively long-lasting protection in swine. Similarly cattle inoculated with one dose of this recombinant vector are rapidly protected from direct and contact exposure to virulent virus. Furthermore, cattle given two doses of this vaccine developed high levels of FMDV-specific neutralizing antibodies, but did not develop antibodies against viral NS proteins demonstrating the ability of FMD subunit vaccinated animals to be differentiated from infected animals. To stimulate early protection prior to the vaccine-induced adaptive immune response we inoculated swine with the antiviral agent, type I interferon, and induced complete protection within 1 day. Protection can last for 3-5 days. The combination of the FMD marker vaccine and type I interferon can induce immediate, within 1 day, and long-lasting protection against FMD. Thus, this combination approach successfully addresses a number of concerns of FMD-free countries with the current disease control plan. By rapidly limiting virus replication and spread this strategy may reduce the number of animals that need to be slaughtered during an outbreak.

The first category contains models utilizing remote sensing (RS) observations of surface radiometric temperature to estimate aerodynamic surface temperature and solve the terrestrial energy balance. The second category contains combined water and energy balance (WEB) approaches that simultaneously solve for surface temperature and energy fluxes based on observations of incoming radiation, precipitation, and micrometeorological variables. To date, few studies have focused on cross comparing model predictions from each category. Land surface and remote sensing datasets collected during the 2002 Soil Moisture-Atmosphere Coupling Experiment (SMACEX) provide an opportunity to evaluate and intercompare spatially distributed surface energy balance models. Intercomparison results presented here focus on the ability of a WEB-SVAT approach [the TOPmodel-based Land-Atmosphere Transfer Scheme (TOPLATS)] and an RS-SVAT approach [the Two-Source Energy Balance (TSEB) model] to accurately predict patterns of turbulent energy fluxes observed during SMACEX. During the experiment, TOPLATS and TSEB latent heat flux predictions match flux tower observations with root-mean-square (rms) accuracies of 67 and 63 W m-2, respectively. TSEB predictions of sensible heat flux are significantly more accurate with an rms accuracy of 22 versus 46 W m-2 for TOPLATS. The intercomparison of flux predictions from each model suggests that modeling errors for each approach are sufficiently independent and that opportunities exist for improving the performance of both models via data assimilation and model calibration techniques that integrate RS- and WEB-SVAT energy flux predictions.

The parallel resistance formulation does not consider interaction between the soil and canopy fluxes, whereas the series resistance algorithms provide interaction via the computation of a within-air canopy temperature. Land surface temperatures were derived from high-resolution Landsat Thematic Mapper (TM)/Enhanced Thematic Mapper (ETM) scenes and aircraft imagery. These data, along with tower-based meteorological data, provided inputs for the two-source energy balance model. Comparison of the local model output with tower-based flux observations indicated that both the parallel and series resistance formulations produced basically similar estimates with root-mean-square difference (RMSD) values ranging from approximately 20 to 50 W m-2 for net radiation and latent heat fluxes, respectively. The largest relative difference in percentage [mean absolute percent difference (MAPD)] was for sensible heat flux, which was approximately 35%, followed by a MAPD approximately 25% for soil heat flux, approximately 10% for latent heat flux, and a MAPD < 5% for net radiation. Although both series and parallel versions gave similar results, the parallel resistance formulation was found to be more sensitive to model parameter specification, particularly in accounting for the effects of vegetation clumping resulting from row crop planting on flux partitioning. A sensitivity and model stability analysis for a key model input variable, that is, fractional vegetation cover, also show that the parallel resistance network is more sensitive to the errors vegetation cover estimates. Furthermore, it is shown that for a much narrower range in vegetation cover fraction, compared to the series resistance network, the parallel resistance scheme is able to achieve a balance in both the radiative temperature and convective heat fluxes between the soil and canopy components. This result appears to be related to the moderating effects of the air temperature in the canopy air space computed in the series resistance scheme, which represents the effective source height for turbulent energy exchange across the soil-canopy-atmosphere system.

The studies were conducted in early June over an alfalfa field and in mid-September over a short grass field. Several statistical exploratory, graphical, and multiple-comparison procedures were used to evaluate each daily variable. Daily total or average data were used to estimate a pooled standard error and corresponding LSD values at the P = 0.05 and P = 0.01 levels using univariate procedures. There were no significant sensor differences in any of the daily measurements for either intercomparison period. Hourly averaged data were used to estimate a pooled standard error and corresponding LSD values at the P = 0.05 and P = 0.01 levels using mixed model procedures. Sensor differences for pre- and post-intercomparisons were minimal for hourly and daily values of CO2, water vapor, sensible heat, friction velocity, and standard deviation for vertical wind velocity. Computed LSD values were used to determine significant daily differences and threshold values for the variables monitored during the SMACEX campaign.

Many factors exert controls on soil respiration, including temperature, soil water content, organic matter, soil texture, and plant root activity. This study was conducted to quantify soil respiration in the Walnut Creek watershed in central Iowa, and to investigate the factors controlling this process. Six agricultural fields were identified for this investigation: three of the fields were cropped with soybean [Glycine max (L.) Merr.] and three were cropped with corn (Zea mays L.). Within each field, soil respiration was measured at nine locations, with each location corresponding to one of three general landscape positions (summit, side slope, and depression). Soil respiration was measured using a portable vented chamber connected to an infrared gas analyzer. Soil samples were collected at each location for the measurement of soil water content, pH, texture, microbial biomass, and respiration potential. Field respiration rates did not show a significant landscape effect. However, there was a significant crop effect, with respiration from cornfields averaging 37.5 g CO2 m-2 day-1 versus an average respiration of 13.1 g CO2 m-2 day-1 in soybean fields. In contrast, laboratory measurements of soil respiration potential, which did not include plant roots, showed a significant landscape effect and an insignificant cropping system effect. Similar relationships were observed for soil organic C and microbial biomass. Additional analyses indicate that corn roots may be more important than soybean roots in their contribution to surface CO2 flux, and that root respiration masked landscape effects on total soil respiration. Also, the failure to account for soil respiration may lead to biased estimates of net primary production measured by eddy covariance.

Polymorphic microsatellite markers were developed for NITR2, NITR4 and RAD23B from short-tandem repeats in the available sequence. Polymorphic microsatellite markers were developed for the remaining 15 genes by short-tandem repeat-anchored primer sequencing of catfish bacterial artificial chromosomes. Two gene clusters (MYOG-NRAMP-ADORA1) and (CCR4-CCR2-CCR5) displayed conservation of synteny between catfish and mammals. Assignment of 18 new genes to the catfish linkage map will further advance integration of genetic and physical maps and comparative mapping between channel catfish and map rich species.

It is unclear if diet can influence the survivability of E. coli O157:H7 in the gastrointestinal system or in feces in the environment. Feces from cattle fed bromegrass hay or corn silage diets were inoculated with E. coli O157:H7, and the survival of this pathogen was analyzed. When animals consumed bromegrass hay for 1 month, E. coli O157:H7 cells were recovered for >120 days. Viable E. coli O157:H7 cells in feces from animals fed corn silage were detected until day 45 and differed little with the time on the diet. To determine if forage phenolic acids affected the viability of E. coli O157:H7, feces from animals fed corn silage or cracked corn were amended with common forage phenolic acids. When 0.5% trans-cinnamic acid or 0.5% para-coumaric acid was added to feces from silage-fed animals, the E. coli O157:H7 death rate was increased significantly (17-fold and 23-fold, respectively) compared to that with no addition. In feces from animals fed cracked corn, E. coli O157:H7 death rates were increased significantly with the addition of 0.1% and 0.5% trans-cinnamic acid (7- and 13-fold), 0.1% and 0.5% p-coumaric acid (3- and 8-fold), and 0.5% ferulic acid (3-fold). These data suggest that phenolic acids common to forage plants can decrease viable counts of E. coli O157:H7 shed in feces.

Volume-compensation principles were used to route multiple demands in multiple-pool canal systems. The volume-compensation method schedules each demand change individually under the assumption of a series of steady states and superimposes the individual results. Volume-compensation routing schedules were computed for two of the test cases proposed by the ASCE Task Committee on Canal Automation. Alternative routing schedules were computed with the gate-stroking method, which is an inverse solution of the unsteady-flow equations. Both solutions were tested through unsteady-flow simulation. While not as effective as gate-stroking solutions, volume-compensation solutions performed satisfactorily under ideal flow control conditions. When subjected to realistic operational constraints, specifically constraints on the flow regulation interval, and also to incorrect canal hydraulic roughness information, both methods performed similarly.

Bacterial strains were isolated from orchid plants exhibiting disease symptoms in Hawaii. Small to large leaf spots with or without water-soaking or soft rots were observed on various orchid genera, including Dendrobium, Oncidium, and Miltonia spp. and hybrids. Bacteria isolated and cultured from the lesions were tentatively identified using analytical profile index (API) strips and standard physiological and biochemical tests, and confirmed by species-specific polymerase chain reaction and sequencing of the 16S rRNA gene. The variation in pathogenic, morphological, cultural, and molecular characteristics of the orchid isolates also was evaluated. In our studies, a gramnegative, aerobic, rod-shaped bacterium that produced pale yellow, opaque, round colonies with entire margins on nutrient broth yeast extract agar (NBY) was isolated consistently from diseased orchid plants. On yeast dextrose calcium carbonate agar, the isolates produced brownish yellow, nonmucoid colonies, with the majority of the strains secreting a diffusible yellow or tan pigment into the media. The bacterium was identified as Burkholderia gladioli. Molecular analysis indicated very little diversity in the 16S rDNA gene. Testing B. gladioli isolates using media containing copper or streptomycin indicated varying levels of resistance (copper resistant = Cu super(r); streptomycin resistant, Sm super(r)), with approximately 75% of the strains resistant to copper and 94% of the strains resistant to streptomycin. The minimum inhibitory concentration (MIC) of cupric sulfate among Cu super(r) strains ranged from 50 to 1,000 mu g/ml and the MIC of streptomycin was 50 to 100 mu g/ml for all Sm super(r) B. gladioli strains tested. Field and laboratory data suggest the frequent use of these chemicals in nurseries may have inadvertently resulted in the development of copper and streptomycin resistance in B. gladioli from orchids.

Observations over a broad range of initial densities with a wild-type and a genetically engineered strain of the filamentous fungus, Trichoderma virens (Arx), in soil and autoclaved soil differed from these predictions. The per capita growth response of T. virens in vitro was found to be density dependent on potato dextrose agar, but density independent on water agar. Further experiments with a defined, carbon-free medium (Vogel's medium) and, with the same medium containing sucrose, indicated that density dependent per capita growth occurred in the nutrient-rich medium but not the oligotrophic medium. This hypothesis was tested and supported experimentally through observation of density dependent per capita growth after adding nutrients to autoclaved soil. Development of better models of population dynamics will be important to predict successfully the likelihood and extent of establishment after field release of microorganims.

Two volumetric cyclone samplers (PAS450 and Burkard Cyclone) and two passive samplers (funnels and panels) were evaluated. The PAS450 collected no detectable bacteria in any trial. The Burkard cyclone consistently collected spray, but was found to do so even when the power was turned off. Thus, the Burkard cyclone essentially functioned passively, negating the advantage of a volumetric sampler for this application. Panels collected the greatest volume of splash followed by funnel samplers. CFU of Xanthomonas axonopodis pv. citri per ml collected were significantly different between Burkards and panel samplers, but panels and funnels collected similar concentrations (Burkards, funnels, and panels collected 1,182, 1,426, and 2,667 CFU per ml, respectively). Positive correlations were found between the volume and the total X. axonopodis pv. citri collected, and between CFU per ml and total collected for panel and funnel samples. However, there was no correlation between CFU per ml and volume collected for either sampler. The Burkard sample showed a strong positive correlation (P < 0.01) between volume collected, total number of X. axonopodis pv. citri collected, and CFU per ml. The CFU per ml collected by the panels and funnels were similar (coefficient of determination, R super(2) = 0.97), compared with the relationship between the Burkard and panel catches (R super(2) = 0.68), or between the Burkard and funnel catches (R super(2) = 0.62). Panels collected the greatest volume, and effectively collected bacteria-laden windblown splash. The greater sampling area of the panels allowed a more representative sample than the other methods tested.

P. amaranthicola infected A. hybridus at 20, 25, 30, and 35 degree C but the disease level achieved at 20 degree C may not be sufficient to cause high plant mortality. Plant mortality was also significantly lower in plants that were exposed to 4 h of dew. Plants at less than two- to two- to four-leaf stage were more easily killed than older plants, and increasing conidial concentration from 10 super(5) to 10 super(6) or 10 super(7) conidia ml super(-1) did not result in higher mortality levels. Among the adjuvants tested, polyalkyleneoxide-modified heptamethyltrisiloxane, algal polysaccharide, hyrdroxyethyl cellulose, and octylphenoxy polyethoxyethanol reduced conidial germination. Conidia applied with invert emulsion caused the highest plant mortality (74%) but invert emulsion alone caused 33% plant death due to phytotoxicity. Results indicate that P. amaranthicola can infect and kill Amaranthus spp. under a range of temperature, dew period, and inoculum levels and, therefore, has good potential as a bioherbicide agent.

Anguina sp. is also a vector of the bacterial pathogen Rathayibacter rathayi, which causes galls or gummosis in orchardgrass (Dactylis glomerata) panicles. The percentage of orchardgrass panicles infected or percentage of seed loss from Anguina sp. or R. rathayi in five commercial orchardgrass seed-production fields in Oregon during 2003 and 2004 was determined. The percentage of panicles with Anguina sp. ranged from 9 to 24%, although the percentage of seed replaced by Anguina sp. was less than 0.2%. The number of galls per panicle ranged from 1 to 29. However, more than 50% of Anguina-infested panicles contained only a single Anguina gall and few panicles had eight or more galls. The percentage of panicles with R. rathayi ranged from 3 to 27%. Percentage of seed loss from R. rathayi ranged from 0.1 to 7.3%. Seed loss in orchardgrass seed-production fields assessed for both Anguina sp. and R. rathayi was found to be as great as 8%. The number of Anguina galls remaining in fields following harvest ranged from O to 40 per square meter.

However, the literature on the use of culmen length to determine sex is inconsistent, with reported overlap in culmen lengths for males and females ranging from 1 mm to >120 mm. Morphological measurements from 188 American White Pelicans collected in Mississippi and Louisiana whose sex was determined by dissection and gonadal inspection were measured. The use of culmen length alone was used to determine gender for this sample by establishing the minimum observed culmen length for males and the maximum observed culmen length for females that provided the fewest incorrect determinations for each gender. A multivariate discriminant function model was developed to determine sex from our data and compared the diagnostic accuracy of the model with the accuracy based on culmen length alone. Both methods were validated using an independently collected sample of 22 pelicans from Florida. A culmen length of greater than or equal to 310 mm for males and less than or equal to 309 mm for females from our data correctly classified sex for 99% of American White Pelicans from our Mississippi and Louisiana samples and 95% of AWPE for the Florida sample. Culmen length and wingcord length were significant variables in the discriminant function model. The resulting model correctly classified sex of 97% of the birds and 94% of the independent Florida sample. The culmen length alone predicted the sex of American White Pelicans as well as multivariate methods and provides an accurate simple, non-lethal method for sexing the species.

Although many pelican colonies have not been surveyed since the early 1980s, we present the most current survey numbers available for North American colonies. Using available data (1998-2001) and the North American Continental Divide to delineate eastern from western metapopulations, 27 colonies and 48,240 nests in the East and 15 colonies and 18,790 nests in the West were documented, giving a total of about 134,000 breeding pelicans in North America. The nest numbers of 20 eastern and western colonies that were surveyed during 1979-81 and again in 1998-2001 were also compared to determine if pelican numbers are changing. The number of AWPE nests in those colonies has more than doubled since the 1979-81 surveys. Because current data for colonies in part of the United States and much of Canada are lacking and about 20 years have passed since more complete surveys were done, we propose that regular and coordinated North American pelican surveys should be initiated.

The production of farm-raised Channel Catfish (Ictalurus punctatus) in the southeastern United States has increased dramatically in the last 25 years. In 1990, U.S. Department of Agriculture Wildlife Services offices in Arkansas, Louisiana and Mississippi began receiving complaints concerning the foraging of pelicans in commercial Channel Catfish ponds. Because of the relatively shallow depth and high fish-stocking rates used by most catfish producers, these ponds provide an ideal foraging environment for the American White Pelican. Although the impact of foraging pelicans can be economically significant, the potential for pelicans to transmit trematode infections and other diseases to aquaculture facilities can be more destructive.

The simulation was run at a 3 h time step and a spatial resolution of 250 m. Spatial field time series of meteorological input data were obtained using various spatial interpolation and simulation methods. The variables include precipitation, air temperature, dew point temperature, wind speed, and solar and thermal radiation. The goal was to use readily available data and relatively straightforward, yet physically meaningful, methods to develop the spatial fields. With these meteorological fields as input, the simulated fields of snow water equivalent, snow depth, and snow covered area reproduce observations very well. The simulated snowmelt fields are also used as input to a spatially distributed hydrologic model to estimate streamflow. This gives an additional verification of the snowmelt modelling results as well as provides a linkage of the two models to generate hydrographs for water management information. This project is a demonstration of spatially distributed energy balance snowmelt modelling in a large mountainous catchment using data from existing meteorological networks. This capability then suggests the potential for developing new spatial hydrologic informational products and the possibility of improving the accuracy of the prediction of hydrologic processes for water and natural resources management.

Plant residue remaining at the soil surface from prior crops serves as a vapor barrier against water loss, reduces raindrop impact energy, slows surface runoff, and often increases infiltration. By increasing infiltration, the potential for greater plant-available water can be enhanced and irrigation requirements reduced. Five years of data were collected to quantify the hydrologic differences between strip till and conventional till production systems. Surface runoff and lateral subsurface flow were measured on six 0.2 ha plots in South Georgia in order to quantify the water-related effects of conservation tillage. Significant differences in surface and subsurface water losses were observed between the conventional and strip tilled plots. Surface runoff from the conventionally tilled plots exceeded that from the strip tilled plots, while subsurface losses were reversed. Surface runoff losses from the conventionally tilled plots exceeded those from the strip tilled plots by 81% (129 mm/year). Shallow lateral subsurface losses from the strip tilled plots exceeded those from the conventionally tilled plots by 73% (69 mm/year). Overall, a net annual gain of 60 mm of water was observed for the strip tilled plots.

This study was undertaken to characterize the hydrology of two karst aquifers within this watershed before significant increases in impervious surfaces take place. The specific objectives of this study were to: 1) use dye tracing to delineate the recharge area for Hunters Cave (HC); 2) quantify and summarize annual and monthly stream discharge at the resurgence of HC and Devils Icebox (DI) caves; and 3) characterize the chemical and physical status of the cave streams relative to temperature, pH, specific conductance, dissolved oxygen, and turbidity. The quantity and quality of the water at the resurgence of both cave streams was monitored from April 1999 to March 2002. Both recharge areas were determined to be of similar size (33.3 km super(2) for HC and 34.0 km super(2) for DI) and were formed in the same geologic strata. Average annual discharge was 55,900 m super(3) km super(-2) at DI and 35,200 m super(3) km super(-2) at HC. Relative discharge, as a percent of annual precipitation, averaged 6.1% at DI and 3.8% at HC. Average monthly discharge was 2,930 m super(3) km super(-2) at HC and 4,650 m super(3) km super(-2) at DI; however, median instantaneous discharge over the three years was about 18% higher at HC (74 m super(3) h super(-1)) compared to DI (63 m super(3) h super(-1)). Turbidity and pH showed the largest differences between sites over the three years. The higher turbidity and lower pH at DI reflected the greater magnitude and duration of runoff events for this system. The physical characteristics of the two recharge areas explained the observed differences in discharge. The HC recharge area is characterized by limited sub-surface conduit development, small conduits, short flow paths from surface to resurgence, and predominantly allogenic recharge. The DI recharge area is characterized by extensive sub-surface-conduit development, large conduits, long flow paths to the resurgence, and autogenic and allogenic recharge.

However, dynamic temperature and shallow hydrologic conditions also influence the measured EC sub(a) and need to be considered. Therefore, the impact of temperature (air, soil) and shallow hydrologic conditions (soil moisture content, water table depth) on the magnitude and spatial patterns of EC sub(a) was evaluated. Eighty-eight EC sub(a) mapping surveys were conducted at a single test plot over an interval of two years. Soil electrical conductivity was measured by electromagnetic induction (EMI) at primary field frequencies of 8190, 14610, and 20010 Hz. Because results were similar at all three frequencies, analyses focused on the 14610 Hz data. The EC sub(a) surveys were grouped into four time periods for analysis based upon factory recalibration of the sensor, climate changes, and a shift in instrument response. Reduced values of measured EC sub(a) occurred with air temperatures at or below 12 degree C and/or soil temperatures at or below 8 degree C. Correlation analysis within each of the four data groups showed that the average EC sub(a), within the test plot, was most strongly affected by near-surface volumetric moisture content (r sub(MC-ECa: Grp. Avg.) = 0.73), followed by water table depth (r sub(WTD-ECa: Grp. Avg.) = -0.42), soil temperature (r sub(ST-ECa: Grp. Avg.) = 0.14), and ambient air temperature (r sub(AT-ECa: Grp. Avg.) = -0.10). Correlation analysis of spatial EC sub(a) patterns between pairs of EMI surveys, conducted under a range of temperature and shallow hydrologic conditions, produced r sub(Spatial: ECa vs. ECa) values averaging 0.63 (standard deviation equaled 0.17), indicating that spatial EC sub(a) patterns remain relatively consistent over time. These EC sub(a) results indicate that the spatial EC sub(a) response is governed to a large extent by the spatial changes in soil properties and less by changes in shallow hydrologic conditions.

It also causes allergic reactions in humans. A. flavus infects agricultural crops and stored grains and produces the most toxic and potent carcinogic metabolites such as aflatoxins and other mycotoxins. Breakthroughs in A. flavus genomics may lead to improvement in human health, food safety, and agricultural economy. The availability of A. flavus genomic data marks a new era in research for fungal biology, medical mycology, agricultural ecology, pathogeni-city, mycotoxin biosynthesis, and evolution. The availability of whole genome microarrays has equipped scientists with a new powerful tool for studying gene expression under specific conditions. They can be used to identify genes responsible for mycotoxin biosynthesis and for fungal infection in humans, animals and plants. A. flavus genomics is expected to advance the development of therapeutic drugs and to provide information for devising strategies in controlling diseases of humans and other animals. Further, it will provide vital clues for engineering commercial crops resistant to fungal infection by incorporating antifungal genes that may prevent aflatoxin contamination of agricultural harvest.

For land modeling applications such as forecast initialization, some of the impact of time-invariant sources can be removed given known differences between observed and modeled soil moisture climatologies. Nevertheless, the distinction is seldom made when evaluating remotely-sensed soil moisture products. Here we describe an Observing System Simulation Experiment (OSSE) for radiometer-only soil moisture products derived from the NASA Hydrosphere States (Hydros) mission where the impact of time-invariant errors is explicitly removed via the linear rescaling of retrievals. OSSE results for the 575,000 km super(2) Red-Arkansas River Basin indicate that climatological rescaling may significantly reduce the perceived magnitude of Hydros soil moisture retrieval errors and expands the geographic areas over which retrievals demonstrate value for land surface modeling applications.

We acoustically detected eight species on the FEF, including the endangered Myotis sodalis. The presence of Lasiurus cinereus, M. lucifugus, M. sodalis, and Pipistrellus subflavus was associated more with riparian areas than upland areas. Both univariate comparisons and multiple logistic regression modeling showed that the probability that clutter-adapted foraging species such as M. septentrionalis and M. sodalis would be detected was greater as forest canopy cover increased or forest canopy gap size decreased, whereas the opposite was true for open-adapted foraging species such as Eptesicus fuscus and L. cinereus. The overall proportion of unidentifiable bat echolocation sequences to those identified to species was related to upland sites with increasing forest canopy cover indicating some sampling bias between cluttered and uncluttered habitats. However, given sufficient sample points, bat community surveys using acoustical detection show the ability to quickly develop generalized habitat associations for rugged areas such as the central Appalachians where traditional mist-net survey efforts often are logistically difficult and are lacking in scope. Moreover, these acoustical surveys also could lend themselves to species-specific predictive mapping of foraging habitat as well as allowing researchers to formulate testable hypotheses about detailed bat habitat relationships to be definitively tested with radio-telemetry techniques.

In their descent from walled bacterial ancestors, phytoplasmas underwent massive genome reduction, resulting in some of the smallest cellular genomes known in nonsymbiotic bacteria. While requirements for in vitro culture of phytoplasmas remain unknown, two opposing reports have appeared concerning genes encoding the ability of phytoplasmas to synthesize folates de novo. One study found pseudogene homologs of folP and folK, obviating folate synthesis in "Candidatus Phytoplasma asteris"-related strain CPh, whereas, a separate study found intact genes encoding a complete folate biosynthesis pathway in "Ca. Phytoplasma asteris"-related strain OY. To resolve the apparent conflict, we hypothesized that evolutionary adaptation to the availability of folate and/or other metabolites in host cells is an ongoing process in the phytoplasma clade that is reflected in part by differences among phytoplasmas in the status of genes of the folate biosynthesis pathway. By studying folP and folK loci in 11 closely related phytoplasmas, we determined that these essential folate biosynthesis genes are intact in some phytoplasmas but are deteriorating in closely related strains. We suggest that the status of the folate biosynthesis pathway and the course of gene decay are lineage-specific, predicting the eventual, lineage-related loss of recognizable folP and folK homologs in phytoplasma genomes.

The persistence of pathogenic Brucella spp. in domestic livestock or free-ranging wildlife remains unresolved, despite decades of regulatory efforts worldwide. Although vaccination is probably the most economic control measure, administration of currently available vaccines alone is not sufficient for elimination of brucellosis in any host species. Complacency in brucellosis control programs usually results in failure, or at best, limited reductions in disease prevalence or incidence of human infections. New brucellosis vaccines with high efficacy and safety are needed that address the diversity in host species and can be more widely applied under field conditions. Development of safer and more efficacious vaccines alone, or combined with enhancements or increased emphasis on other regulatory program components, could have tremendous impact on reducing the worldwide prevalence of brucellosis and the associated zoonotic infections.

Gilb. causes laminated root rot (LRR), a major disease affecting growth and survival of Pseudotsuga menziesii (Mirb.) Franco (Douglas-fir) and other commercially important conifer species throughout the Pacific Northwest. Stump removal or nitrogen (N) fertilization, or both, have been suggested as management strategies for some root diseases but have not been tested previously for LRR in a replicated field study. Independent studies, using the same experimental design, were established in five Douglas-fir stands in Oregon and Washington. The stands were surveyed preharvest and postharvest (clearcut). Each P. weirii-infected entity (standing dead or down trees and stumps) was marked, and the location of its center was mapped. In each clearcut, a 2x4 set of factorial treatments of stump removal in combination with N fertilization was applied to 0.04ha circular plots and replicated five to seven times. Treatments, applied in the fall, included stump removal with a bulldozer (either all stumps removed or the plot left undisturbed) and broadcast fertilization with ammonium nitrate (0, 336, 672, or 1345kgNha super(-) super(1)). Douglas-fir seedlings were planted in the winter following treatment application. When the stand was considered established, each plot was thinned to a spacing of about 2.4m inter-tree spacing and the trees tagged. Diameter at breast height, total height, and mortality of trees were recorded every 2-5 years. A total of 7827 tagged trees on 239 plots were observed for up to 27 growing seasons following treatment. Stumping caused a significant reduction in seedling mortality due to LRR at all five study areas. The mean LRR-caused mortality on stumped and nonstumped plots was 2.4 and 9.1%, respectively. Fertilization did not cause a significant change in LRR-caused mortality of seedlings at any of the study areas. Nitrogen fertilization before planting increased growth of Douglas-fir seedlings but only in some stands. Nitrogen fertilizer can have a positive residual effect on growth of Douglas-fir for at least 23 years. Effects on soil of heavy equipment used in stumping operations did not reduce subsequent Douglas-fir survival or growth. There was a mean reduction in wood volume of 24.8% in areas where LRR was observed compared to areas where it was not found.

We conducted aboveground biomass harvests in 18-year-old loblolly pine growing in single-, double-, and quadruple-row configurations at 2.1m between trees in the row, and initial densities of 308, 568, and 932 treesha super(-) super(1). In the double- and quadruple-row configurations, rows were 2.4m apart while alleys were 14.6m wide in all configurations. Trees were felled from single, double (east and west orientations) and, the exterior east and one of the interior (trees identified as QR2) quadruple rows, and separated into bole, branches, twigs (<2cm in diameter), and foliage. In total, 60 trees within the 25-29cm DBH class were sampled (five configurationsxthree trees per rowxtwo pruning regimesxtwo replicates). Averaged across pruning regimes, absolute total aboveground biomass per tree ranged from 366kg in single-row trees to 231kg in QR2-trees while bole biomass varied from 185kg in single-row trees to 143kg in QR2-trees. Configuration affected relative biomass partitioning to boles (P<0.05), which ranged, on an average, from 60% of total tree biomass in quadruple rows to 52% in single rows, branch (P<0.05), which varied from 30% in single rows to 24% in quadruple rows, and foliage (P<0.001), which ranged from 12% in single rows to 8% in quadruple rows. Bole DBH and available ground space per tree (as covariates) did not affect biomass partitioning as neither did pruning, although pruning markedly improved log quality. Basal areas in single-, double-, and quadruple-row configurations in the silvopasture were 11, 19, and 34% greater than the projected basal areas for adjacent loblolly pine plots with similar stand density.

AN - 68773547; 16277434 AB - Fusarium head blight (FHB) of wheat (Triticum aestivum L.), caused by the fungus Fusarium graminearum, is a major concern worldwide. FHB grain is reduced in yield, may fail to germinate, and is often contaminated with deoxynivalenol, a trichothecene mycotoxin linked to a variety of animal diseases and feed refusals. Annual losses in the tens of millions of dollars due to FHB underscore the need to develop improved methods of disease control and prevention. Previous research has identified deoxynivalenol biosynthesis as a virulence factor on wheat. Recently, we found that the TRI14 gene of F. sporotrichioides, closely related to F. graminearum, was not required for synthesis of a related trichothecene, T-2 toxin. TRI14 does not share similarity with any previously described genes in the databases. In this study, we examined the role that F. graminearum TRI14 may play in both deoxynivalenol synthesis and in virulence on wheat. TRI14 deletion mutants synthesize deoxynivalenol on cracked maize kernel medium and exhibit wild-type colony morphology and growth rate on complex and minimal agar media. However, FHB assays on greenhouse-grown wheat indicate that FgDeltaTri14 mutants cause 50-80% less disease than wild type and do not produce a detectable quantity of deoxynivalenol on plants. We discuss a number of possible roles that TRI14 may play in the disease process.

Tensile properties depended on the initial water content of sugar beet pulp and the process by which composites were manufactured. In comparison with sugar beet pulp, the composite showed improved water resistance. This can be attributed to the hydrophobic character of PLA and pulp-matrix interactions. The composite thermoplastics showed suitable properties for potential use as lightweight construction materials.

AN - 68774892; 16260728 AB - Perchlorate is a goitrogenic anion that competitively inhibits the sodium iodide transporter and has been detected in forages and in commercial milk throughout the U.S. The fate of perchlorate and its effect on animal health were studied in lactating cows, ruminally infused with perchlorate for 5 weeks. Milk perchlorate levels were highly correlated with perchlorate intake, but milk iodine was unaffected, and there were no demonstrable health effects. We provide evidence that up to 80% of dietary perchlorate was metabolized, most likely in the rumen, which would provide cattle with a degree of refractoriness to perchlorate. Data presented are important for assessing the environmental impact on perchlorate concentrations in milk and potential for relevance to human health.

We compared small-mammal capture rates in 20 forest stands (4 replicates of 5 treatments) for 2 years prior to harvest treatments, and 1.5, 3.5, and 5.5 years after treatment. We also examined relationships among small mammals, treatments, and habitat conditions. Before harvest, all stands where characterized by high basal areas (BA), little understory vegetation, and low small-mammal capture rates. Compared with pre-harvest numbers, the number of individuals captured increased nearly five-fold in treated stands 1.5 years after harvest. After harvest, capture rates for all taxa combined were significantly greater in harvested stands (regardless of treatment) than in unharvested controls. Fulvous harvest mice (Reithrodontomys fulvescens) capture rates were greatest in clearcuts. Fulvous harvest mice, cotton rats (Sigmondon hispidus), and pine voles (Microtus pinetorum) were associated with abundant herbaceous vegetation in the understory and low BA. Eastern woodrats (Neotoma floridana), golden mice (Ochrotomys nuttalli), and Peromyscus spp. were associated with moderate to dense woody vegetation in the understory and intermediate BA levels. No taxon of terrestrial small mammal was captured exclusively in unharvested stands; most taxa we captured appear to be either disturbance-adapted or tolerant to disturbances from timber harvest.

AN - 68729518; 16248573 AB - Isolation and characterization of leaf volatiles in Anemopsis californica (Nutt.) Hook. and Arn. (A. californica) was performed using steam distillation, solid-phase microextraction, and supercritical fluid extraction. Thirty-eight compounds were detected and identified by gas chromatography; elemicin was the major component of the leaf volatiles. While the composition of the leaf volatiles varied with method of extraction, alpha-pinene, sabinene, beta-phellandrene, 1,8-cineole, piperitone, methyl eugenol, (E)-caryophyllene, and elemicin were usually present in readily detectable amounts. Greenhouse-reared clones of a wild population of A. californica had an identical leaf volatile composition with the parent plants. Steam-distilled oil had antimicrobial properties against 3 (Staphylococcus aureus, Streptococcus pneumoniae, and Geotrichim candidum) of 11 microbial species tested. Some of this bioactivity could be accounted for by the alpha-pinene in the oil.

13858351 AB - A variety of different pretreatments can improve the performance of enzymes in nonpolar reaction media. These pretreatments have primarily been studied in isolation; however, interactions between some pairs of pretreatments are known to exist. The presence of these interactions complicates the design of an optimum multifactor pretreatment. Modern design-of-experiments techniques allow the simultaneous optimization of two or more variables. To improve the performance of lipase in a model reaction, we used a technique called the method of steepest ascent to optimize three variables simultaneously: pretreatment pH and sodium phosphate concentration, and the concentration of acetic acid (one of the reactants) in the reaction mixture. In only 26 experimental runs, this optimization process determined a combination of variable settings that yielded a reaction product approx 180 times faster than achieved with untreated enzyme. Evidence is presented to demonstrate that locating this optimum with single-factor experiments would be inefficient. This article demonstrates the efficiency of the method of steepest ascent particularly for evaluation of enzymatic reaction conditions exhibiting significant interactions.

AN - 70121890; 16463975 AB - Occlusion of the trachea and decapitation were compared with a conventional unilateral neck cut for effects on bacteria entering into the respiratory tract of broiler carcasses during scalding. In experiment 1, the trachea was occluded prior to the carcass entering the scalder to determine if bacterial recovery from the respiratory tract could be diminished. The first carcass was removed at the end of bleeding, and a plastic cable tie was placed around the neck of a second carcass and tightened to occlude the trachea. After proceeding through the triple-tank immersion scalder, the second carcass (trachea occluded) was removed, and a third carcass (without the trachea occluded during scalding) was removed. In experiment 2, after being stunned, carcasses were unilaterally bled or decapitated. Unilaterally bled and decapitated carcasses were removed at the end of bleeding and after scalding. In both experiments, trachea were cannulated, and respiratory tract rinses were collected. For experiment 1, the numbers of bacteria recovered (log10 cfu/mL of rinse) from prescald nonoccluded carcass respiratory tract rinses were 2.5 Escherichia coli, 2.6 coliforms, and 3.2 total aerobes. Respiratory tract rinses from carcasses sampled postscald (without occluding the trachea) had higher bacteria numbers at 4.6 E. coli, 5.0 coliforms, and 5.4 total aerobes. Respiratory tract rinses from carcasses with the trachea occluded prior to scalding had the lowest number of bacteria at 1.9 E. coli, 2.3 coliforms, and 2.7 total aerobes. In experiment 2, the numbers of bacteria recovered from respiratory tract rinses of unilaterally bled or decapitated carcasses did not differ prescald or postscald, although all postscald values were higher (P < 0.05).

AN - 68822763; 16300075 AB - Shell egg microbiology has been studied extensively, but little information is available on how modern U.S. processing conditions impact microbial populations. As regulations are being drafted for the industry, such information can be important for determining processing steps critical to product safety. Five different shell egg surface microbial populations (aerobic bacteria, yeasts and molds, Enterobacteriaceae, Escherichia coli, and Salmonella) were monitored at 12 points along the processing line (accumulator, prewash rinse, washer 1, washer 2, sanitizer, dryer, oiler, scales, two packer head lanes, rewash entrance, and rewash exit). Three commercial facilities were each visited three times, a total of 990 eggs were sampled, and 5,220 microbiological samples were subsequently analyzed. Although variations existed in concentrations of microorganisms recovered from each plant, the patterns of fluctuation for each population were similar at each plant. On average, aerobes, yeasts and molds, Enterobacteriaceae, and E. coli prevalence were reduced by 30, 20, 50, and 30%, respectively, by the end of processing. The microbial concentrations (log CFU per milliliter) in the egg rinse collected from packer head lanes were decreased by 3.3, 1.3, 1.3, and 0.5, respectively, when compared with those of rinses collected from eggs at the accumulator. Salmonella was recovered from 0 to 48% of pooled samples in the three repetitions. Higher concentrations of Salmonella were recovered from preprocessed than from in-process or ready-to-pack eggs. These data indicate that current commercial practices decrease microbial contamination of egg shell surfaces.

AN - 68818639; 16300088 AB - Many consumers assume that broiler chickens grownunder traditional commercial conditions will have more Salmonella than free-range or organic chickens, which usually are less crowded, have access to outside spaces during grow out, and are fed special diets. Despite these perceptions, there is a lack of published information about the microbiological status of free-range and organic chickens. A total of 135 processed free-range chickens from four different commercial free-range chicken producers were sampled in 14 different lots for the presence of Salmonella. Overall, 9 (64%) of 14 lots and 42 (31%) of 135 of the carcasses were positive for Salmonella. No Salmonella were detected in 5 of the 14 lots, and in one lot 100% of the chickens were positive for Salmonella. An additional 53 all-natural (no meat or poultry meal or antibiotics in the feed) processed chickens from eight lots were tested; 25% ofthe individual chickens from 37% of these lots tested positive for Salmonella. Three lots of chickens from a single organicfree-range producer were tested, and all three of the lots and 60% of the individual chickens were positive for Salmonella.The U.S. Department of Agriculture Food Safety and Inspection Service reported that commercial chickens processed from 2000 to 2003 had a Salmonella prevalence rate of 9.1 to 12.8%. Consumers should not assume that free-range or organicconditions will have anything to do with the Salmonella status of the chicken.

AN - 68801932; 16271733 AB - Bioassay-guided fractionation of the ethyl acetate extract of Ruta graveolens roots yielded rutacridone epoxide with potent selective algicidal activity towards the 2-methyl-isoborneol (MIB)-producing blue-green alga Oscillatoria perornata, with relatively little effect on the green alga Selenastrum capricornutum. The diol-analog of rutacridone epoxide, gravacridondiol, which was also present in the same extract, had significantly less activity towards O. perornata. Rutacridone epoxide also showed significantly higher activity than commercial fungicides captan and benomyl in our micro-bioassay against the agriculturally important pathogenic fungi Colletotrichum fragariae, C. gloeosporioides, C. acutatum, and Botrytis cineara and Fusarium oxysporium. Rutacridone epoxide is reported as a direct-acting mutagen, precluding its use as an agrochemical. In order to understand the structure-activity relationships and to develop new potential biocides without toxicity and mutagenicity, some analogs containing the (2-methyloxiranyl)-dihydrobenzofuran moiety with an epoxide were synthesized and tested. None of the synthetic analogs showed comparable activities to rutacridone epoxide. The absolute stereochemistry of rutacridone was determined to be 2'(R) and that of rutacridone epoxide to be 2'(R), 3'(R) by CD and NMR analysis.

AN - 68767902; 16112794 AB - This article discusses an 8-year, ongoing project that evaluates the Environmental Protection Agency's Superfund community involvement program. The project originated as a response to the Government Performance and Results Act, which requires federal agencies to articulate program goals, and evaluate and report their progress in meeting those goals. The evaluation project assesses how effective the Superfund community involvement program is in promoting public participation in decisions about how to clean up hazardous wastes at Superfund sites. We do three things in the article: (1) share our experience with evaluating an Agency public participation program, including lessons learned about methods of evaluation; (2) report evaluation results; and (3) address a number of issues pertaining to the evaluation of public participation in environmental decision-making. Our goal is to encourage more environmental managers to incorporate evaluation into their public participation programs as a tool for improving them. We found that written mail surveys were an effective and economical tool for obtaining feedback on EPA's community involvement program at Superfund sites. The evaluation focused on four criteria: citizen satisfaction with EPA information about the Superfund site, citizen understanding of environmental and human health risks associated with the site, citizen satisfaction with opportunities provided by EPA for community input, and citizen satisfaction with EPA's response to community input. While the evaluation results were mixed, in general, community members who were most informed about and involved in the cleanup process at Superfund sites generally were also the most satisfied with the community involvement process, and the job that EPA was doing cleaning up the site. We conclude that systematic evaluation provides meaningful and useful information that agencies can use to improve their public participation programs. However, there need to be institutionalized processes that ensure evaluation results are used to develop and implement strategies for improvement.

AN - 68767276; 16273433 AB - We measured the concentrations of extractable bioactive compounds in heartwood of live yellow-cedar (Chamaecyparis nootkatensis) trees and five classes of standing snags (1-5, averaging 4, 14, 26, 51, and 81 years-since-death, respectively) to determine how the concentrations changed in the slowly deteriorating snags. Three individuals from each of these six condition classes were sampled at four sites spanning a 260-km distance across southeast Alaska, and the influence of geographic location on heartwood chemistry was evaluated. Cores of heartwood were collected at breast height and cut into consecutive 5-cm segments starting at the pith. Each segment was extracted with ethyl acetate and analyzed by gas chromatography. Concentrations of carvacrol, nootkatene, nootkatol, nootkatone, nootkatin, and total extractives (a sum of 16 compounds) for the inner (0-5 cm from pith), middle (5-10 cm from pith), and surface (outer 1.1-6.0 cm of heartwood) segments from each core were compared within each tree condition class and within segments across condition classes. Heartwood of class 1 and 2 snags had the same chemical composition as live trees. The first concentration changes begin to appear in class 3 snags, which coincides with greater heartwood exposure to the external environment as decaying sapwood sloughs away, after losing the protective outer bark. Within core segments, the concentrations of all compounds, except nootkatene, decrease between snag classes 2 and 5, resulting in the heartwood of class 5 snags having the lowest quantities of bioactive compounds, although not different from the amounts in class 4 snags. This decline in chemical defense is consistent with heartwood of class 5 snags being less decay-resistant than heartwood of live trees, as observed by others. The unique heartwood chemistry of yellow cedar and the slow way it is altered after death allow dead trees to remain standing for up to a century with a profound impact on the ecology of forests in southeast Alaska where these trees are in decline.

AN - 68760556; 16269758 AB - Temperature-sensitive (TS) plasmids were generated through chemical mutagenesis of a derivative of the streptomycin resistance parent plasmid pD70, isolated from Mannheimia hemolytica serotype 1. Three TS plasmids which failed to replicate at or above 42 degrees C in M. hemolytica but which were fully functional below 31 degrees C were selected for further analysis. Two of the TS plasmids were shown by sequencing to possess unique single-base-pair mutations. The third TS plasmid contained a unique base pair substitution and a second mutation that had been previously identified. These mutations were clustered within a 200-bp region of the presumed plasmid origin of replication. Site-directed single-nucleotide substitutions were introduced into the wild-type pD70 origin of replication to confirm that mutations identified by sequencing had conferred thermoregulated replication. Deletion analysis on the wild-type pD70 plasmid replicon revealed that approximately 720 bp are necessary for plasmid maintenance. Replication of the TS plasmids was thermoregulated in Pasteurella multocida and Haemophilus somnus as well. To consistently transform H. somnus with TS plasmid, in vitro DNA methylation with commercially available HhaI methyltransferase was necessary to protect against the organism's restriction enzyme HsoI (recognition sequence 5'-GCGC-3') characterized herein.

AN - 68691620; 16102871 AB - In situ groundwater remediation may be achieved using stationary permeable barriers created by the injection of a substrate, such as innocuous vegetable oil, into the contaminated aquifer. The oil provides the electron donor stimulating microorganisms to degrade or sequester many contaminants. At present, little is known about the best procedures to use when injecting oil into an aquifer. In this investigation, laboratory column and sand tank studies were used as model systems to explore the effect of different injection parameters on the distribution of oil emulsions into water-saturated sand. The parameters investigated included injection pressures of 70, 1400 and 18,000 KPa; injection times of 15, 30, 60 or 120 s; and the influence of an emulsifier, polyoxyethylenesorbitan monooleate (Tween 80), upon the distribution of the injected oil. The longest injection patterns were achieved at 18,000 KPa. A pattern that was 46+/-1.8 cm long was produced with an 18,000 KPa injection for 60 s. Increasing the injection time to 120 s increased the length of the pattern by only 6.5%. Tween 80 at concentrations of 0.05% increased the width of the injection patterns but did not increase the length of the pattern. A multi-ported injection probe might be used to create in situ permeable barriers approximately 1 m wide.

AN - 68686475; 16219503 AB - Batch adsorption and desorption experiments were performed using thirteen agricultural soil samples and five pesticides. Experimental data indicated a gradient in pesticide adsorption on soil: trifluralin >> 2,4-D > isoproturon> atrazine >> bentazone. Atrazine, isoproturon and trifluralin adsorption were correlated to soil organic matter content (r2 = 0.7, 0.82, 0.79 respectively). Conversely, bentazone adsorption was governed by soil pH (r2 = 0.68) while insignificant effect has been shown in the case of 2,4-D. Multiple linear regressions were used to combine relationships between the various soil parameters and the Freundlich adsorption coefficient (K(f)) of each pesticide. Then desorption was assessed since it may reflect some of the interactions involved between the pesticides and the soil components. Adsorbed molecules were released into aqueous solution in the following order: bentazone >> atrazine> isoproturon> 2,4-D >> trifluralin. The occurrence of hysteresis did not allow an accurate interpretation of the pesticide desorption data because of the possible interplay of several processes.

AN - 68684876; 16216624 AB - An estimated 100,000m(3) selenium (Se)-laden drainage sediment resides in the San Luis Drain (SLD) of Central California. This greenhouse study was undertaken to evaluate the feasibility of growing salt- and boron-tolerant plant species in sediment for reduction of Se content by plant extraction. Drainage sediment was collected from the SLD and mixed with control soil (i.e., uncontaminated soil) to the following ratios (sediment:control soil) by volume: 0:3 (i.e., control soil only), 1:2 (i.e., 1/3 sediment and 2/3 control soil), 2:1 (i.e., 2/3 sediment and 1/3 control soil), and 3:0 (i.e., sediment only). Salt-tolerant plant species consisted of canola (Brassica napus var. Hyola 420), tall fescue (Festuca arundinacea var. Au Triumph), salado grass (Sporobulus airoides), and cordgrass (Spartina patens var. Flageo). Increased ratios of sediment:soil resulted in decreased dry matter production for all tested plant species; especially at ratios of sediment:soil greater than 1:2. Plant Se concentrations (mgkg(-1) DM) ranged as follows for plant species at all ratios of sediment:soil: canola (51-72), tall fescue (16-36), and cordgrass and salado grass (9-14). Total Se concentrations in the soil were at least 20% lower at postharvest compared to preplant concentrations for all plant species at each ratio of sediment:soil. In contrast, water-extractable Se concentrations in the soil were at least three times higher at postharvest than at preplant for all plant species, irrespective of the ratio of sediment:soil. Leaching of Se occurred in irrigated bare pots from each respective ratio of sediment:soil over a duration of 60 days. Based upon the downward movement of Se in bare pots of sediment:soil, it may be more prudent to leave the drainage sediment in the SLD, incorporate clean soil, and then grow low maintenance salt-tolerant plants (e.g., cordgrass, salado grass) in the concrete-lined canal. By this means, possible contamination of groundwater with soluble Se will be eliminated, while phytoremediation slowly reduces Se content in the drainage sediment.

AN - 68661574; 16075408 AB - Essential oils from 23 species of plants comprising 14 genera and 4 plant families were obtained by Clevenger-type water distillation. The major compounds in these essential oils were identified with GC-MS and their insecticidal activity against adult turnip aphids, Lipaphis pseudobrassicae (Davis), tested with dosage-mortality bioassays. We examined mortality only for viviparous adults because sizeable aphid populations on crucifer (Brassicaceae) hosts are largely produced by these wingless, parthenogenic females. Twenty-two of the oils were directly applied to aphid females in randomized blocks at concentrations of 0.0, 1.0, 2.5, 5.0 and 10.0 mg ml(-1). Essential oils mixed with a non-toxic emulsifying agent, dimethyl sulfoxide (DMSO), more easily penetrated the waxy insect cuticle. Probit analysis and LC(50) at three different exposures showed aphids were quickly incapacitated and killed by aliphatic aldehydes, phenols and monocyclic terpenes contained in Bifora and Satureja oils and at applied concentrations as low as 0.3 to 1.0 mg ml(-1). Only enough Pimpinella isaurica oil and its three phenylpropanoid fractions were available for testing at a single concentration of 10 mg ml(-1). We could not spare any additional P. isaurica oil for testing at other concentrations. Phenylpropanoids isolated from P. isaurica oil when recombined or left naturally blended in the oil were highly bioactive against L. pseudobrassicae at 10 mg ml(-1).

The addition of dairy compost or solid dairy manure at rates to meet crop phosphorus uptake did not consistently increase E. coli and Enterococcus spp. and fecal coliform bacteria in the soil. We did not detect E. coli in any soil sample after the first sampling day. Seven, 14, 28, 179 and 297 days after solid dairy waste and compost and alum were applied to soil, alum did not consistently affect Enterococcus spp. and fecal coliform bacteria in the soil. We did not detect E. coli in any soil, fresh potato skin or potato wash-water at 214 days after dairy manure or compost application regardless of alum treatment. Dairy compost or solid dairy manure application to soil at rates to meet crop phosphorus uptake did not consistently increase Enterococcus spp. and fecal coliform numbers in bulk soil. Solid dairy manure application to soil at rates to meet crop phosphorus uptake, increased Enterococcus spp. and fecal coliform numbers in potato rhizosphere soil. However, fresh potato skins had higher Enterococcus spp. and fecal coliform numbers when solid dairy manure was added to soil compared to compost, N and P inorganic fertilizer and N fertilizer treatments. We did not find any E. coli, Enterococcus or total coliform bacteria on the exterior of the tuber, within the peel or within a whole baked potato after microwave cooking for 5 min.

AN - 68038795; 16023914 AB - The fate and transport of 2,4-dichlorophenoxyacetic acid (2,4-D) in the subsurface is affected by a complex, time-dependent interplay between sorption and mineralization processes. 2,4-D is biodegradable in soils, while adsorption/desorption is influenced by both soil organic matter content and soil pH. In order to assess the dynamic interactions between sorption and mineralization, 2,4-D mineralization experiments were carried using three different soils (clay, loam and sand) assuming different contact times. Mineralization appeared to be the main process limiting 2,4-D availability, with each soil containing its own 2,4-D decomposers. For the clay and the loamy soils, 45 and 48% of the applied dose were mineralized after 10 days. By comparison, mineralization in the sandy soil proceeded initially much slower because of longer lag times. While 2,4-D residues immediately after application were readily available (>93% was extractable), the herbicide was present in a mostly unavailable state (<2% extractable) in all three soils after incubation for 60 days. We found that the total amount of bound residue decreased between 30 and 60 incubation days. Bioaccumulation may have led to reversible immobilization, with some residues later becoming more readily available again to extraction and/or mineralization.

We focus on the demand for a weak complement to the ecosystem services-farm labor-and account for spatial dependence due to economic interactions, ecosystem processes, and data integration. The estimated models have theoretically expected properties across eight different specifications. We find strong evidence that forest ecosystem services provide economically substantive benefits to local people and that these services would be substantially undervalued if spatial dependence is ignored.

We developed a 2,654-element Euphorbiaceae cDNA microarray using 1,886 sequenced cDNAs from the model perennial weed leafy spurge, 384 cDNAs from cassava, and 384 control genes from other plant, animal, and bacterial species. This array was used to follow changes in gene expression in root buds of leafy spurge following loss of paradormancy. The differential expression of several genes previously identified as being induced following loss of paradormancy was confirmed by microarray analysis. In addition, genes encoding an asparagine synthase, a phosphate-inducible protein, and a curculin-like (mannose-binding) lectin family protein were found to be rapidly up-regulated upon loss of paradormancy. Several genes involved in flavonoid biosynthesis were found to be rapidly down-regulated upon loss of paradormancy.

However, the role of prfA in the ability of L. monocytogenes to cause infection via the gastrointestinal (GI) tract has not been clearly established. In this study, we used a prfA transposon mutant of L. monocytogenes F2365, a serotype 4b strain, to assess the role of prfA in the pathogenesis of gastrointestinal listeriosis in mice. We found that the prfA mutant was able to survive in the GI tract (i.e., cecum) of mice, albeit in numbers somewhat less than those of the wild-type parent strain of L. monocytogenes. However, mice inoculated with the prfA mutant did not exhibit systemic infection of the spleen and liver, as was noted for mice inoculated with the wild-type parent strain. Survival of the prfA mutant in synthetic gastric fluid at pH 2.5 or 5 was somewhat reduced compared to that of the wild-type strain, as was its ability to invade and multiply within differentiated human intestinal epithelial cells (Caco-2 cells). Prior infection with the prfA mutant gave mice some protection against a subsequent challenge with virulent L. monocytogenes, although much less than that gained by prior gastrointestinal infection with the wild-type parent strain. These findings indicate that the global regulatory gene prfA is dispensable for colonization of the GI tract in mice but not for systemic infection.

Our objective was to determine whether intrauterine inoculation of nulliparous ewes with Arcanobacterium pyogenes and Escherichia coli would produce an antibody response and reduce the severity of subsequent infections. Method of study: Nulliparous ewes (n = 9/treatment) received (i) 'primary intrauterine inoculation' with phosphate-buffered saline (PBS) and 'secondary intrauterine inoculation' with PBS; (ii) primary PBS-secondary 75 x 10 super(7) cfu of A. pyogenes and 35 x 10 super(7) cfu of E. coli (PBS-Bacteria); (iii) primary bacteria-secondary PBS; or (iv) primary bacteria-secondary bacteria (Bacteria-Bacteria). Results: Inoculations evoked an antibody response. Postmortem examinations 6 days after the secondary inoculation indicated that PBS-treated ewes did not develop uterine infections, but all bacteria-treated ewes did. Infections were either less severe or closer to resolution in Bacteria-Bacteria than they were in PBS-Bacteria ewes. Conclusions: Intrauterine inoculation of nulliparous ewes with A. pyogenes and E. coli evokes an antibody response that may help the uterus reduce the severity of subsequent infections.

To achieve this goal, a combination of physically based surface flux models and high-quality remote-sensing data are needed. Data from the ASTER sensor are particularly well-suited to the task, as it collects high spatial resolution (15-90 m) images in visible, near-infrared, and thermal infrared bands. Data in these bands yield surface temperature, vegetation cover density, and land-use types, all critical inputs to surface energy balance models for assessing local environmental conditions. ASTER is currently the only satellite sensor collecting multispectral thermal infrared images, a capability allowing unprecedented surface temperature estimation accuracy for a variety of surface cover types. Availability of ASTER data to study surface energy fluxes allows direct comparisons against ground measurements and facilitates detection of modeling limitations, both possible because of ASTER's higher spatial resolution. Surface energy flux retrieval from ASTER is demonstrated using data collected over an experimental site in central Iowa, USA, in the framework of the Soil Moisture Atmosphere Coupling Experiment (SMACEX). This experiment took place during the summer of 2002 in a study of heterogeneous agricultural croplands. Two different flux estimation approaches, designed to account for the spatial variability, are considered: the Two-Source Energy Balance model (TSEB) and the Surface Energy Balance Algorithm or Land model (SEBAL). ASTER data are shown to have spatial and spectral resolution sufficient to derive surface variables required as inputs for physically based energy balance modeling. Comparison of flux model results against each other and against ground based measurements was promising, with flux values commonly agreeing within 50 W m-2. Both TSEB and SEBAL showed systematic agreement and responded to spatially varying surface temperatures and vegetation densities. Direct comparison against ground Eddy Covariance data suggests that the TSEB approach is helpful over sparsely vegetated terrain.

The National Center for Atmospheric Research (NCAR) regional climate model coupled with the NCAR column radiative model is used to estimate smoke direct radiative forcing and consequent atmospheric perturbations during a smoke season in this region. The smoke optical properties are specified based on the measurements during the smoke, clouds, and radiation-Brazil experiment. The simulations obtain a direct radiative forcing of -16.5Wm-2 over the smoke region. This magnitude, however, is substantially reduced due to atmospheric feedback. Clouds and precipitation are reduced due to smoke. The cloud reduction mainly results from smaller water vapor transport from the ground and the planetary boundary layer to the cloud layer because of the combined effects of reduced turbulent activity and the subsidence tendency. The simulated cloud reduction agrees with a recent finding from satellite measurements. Smoke also leads to the enhancement of a dominant planetary-scale high system. A two-layer structure of warmer air with ascending tendency on top of cooler air with descending tendency is formed due to smoke with strong absorption.

Nelson recently developed a fuel moisture model that includes functions for both heat and moisture transfer. Fuel moisture samples were collected in Hawaii hourly for up to 96h for three litter, one herbaceous, and eight grass fuels at sites ranging from near sea level to 2200m. Weather data were collected every 5min. Observed fuel moistures were compared to predictions from three models-a simplified form of Fosberg's equation (Simple), the Nelson physical model, and a Markov model fit to the observed data. Mean difference, average deviation, and percentage of predictions closer to the observed data than the Simple model were used to evaluate model performance. Performance of the Markov model was best and of the Simple model was poorest. All models underestimated fuel moisture with the Simple model having the greatest errors and the Markov model having the smallest.

Sheep readily graze larkspur in its mature stages, but if they are to be an effective management tool, they must graze it in the early growth stages before cattle enter the allotment. The objective of this study was to determine if sheep could be positively conditioned to graze duncecap larkspur (Delphinium occidentale (S.Wats) S. Wats) early in its growth stages. Eighteen ewes were divided into 3 groups of 6 ewes each. During conditioning, group 1 was offered potted larkspur plants then were gavaged with glucose, the second group was exposed to larkspur plants together as a group (social facilitation), and the third group was an untreated control. In the preference test, the glucose group ate more duncecap larkspur than the social facilitation and control groups. The glucose and control groups were taken to duncecap larkspur-infested mountain rangeland to test the conditioning. In the field grazing trial, the glucose group consumed more larkspur than the control group, but it occurred later in the grazing trial when larkspur was in flower and after desirable forages had been consumed. High levels of diterpenoid alkaloids in larkspur and other alternative palatable forages may have caused ewes to reject larkspur at the beginning of the trial. The sheep were positively conditioned to graze larkspur, but the amount consumed and the timing of consumption was not sufficient to prevent potential cattle poisoning.Original Abstract: Los ovinos son mas resistentes que los bovinos a la intoxicacion por 'Larkspur', por lo que pueden ser usados como una herramienta biologica para apacentar el 'Larkspur' y reducir la intoxicacion del ganando bovino. Los ovinos son capaces de apacentar 'Larkspur' en sus etapas maduras, pero si ellas van a ser una herramienta efectiva de manejo, ellos deben apacentar el 'Larkspur' en las etapas iniciales de crecimiento, antes de que el ganado bovino entre al potero. El objetivo de este estudio fue determinar si los ovinos pudieran ser acondicionados positivamente para apacentar el 'Duncecap larkspur' (Delphinium occidentale (S.Wats) S. Wats) en las etapas iniciales de crecimiento. Un grupo de 18 borregas se dividio en tres grupos de seis animales cada uno. Durante el acondicionamiento, al grupo 1 se le ofrecio plantas de 'Larkspur' en recipientes las cuales fueron adicionadas con glucosa, en el segundo grupo todos los animales fueron expuestos juntos a plantas de 'Larkspur' (Facilitacion social) y el tercer grupo fue el control sin tratamiento. En la prueba de preferencia, el grupo con glucosa comio mas 'Duncecap larkspur' que los grupos de facilitacion social y testigo. Los grupos de glucosa y testigo se llevaron a un pastizal montano infestado con 'Duncecap larkspur' para evaluar el acondicionamiento. En la prueba de apacentamiento en campo. El grupo con glucosa consumio mas 'Larkspur' que el grupo control, pero esto ocurrio al final de la prueba de apacentamiento cuando el 'Larkspur' estaba en floracion y despues de que los forrajes deseables habian sido consumidos. Altos niveles de alcaloides diterpenoides presentes en el 'Larkspur' y la presencia de otros forrajes de alta gustocidad pudo haber causado el rechazo del 'Larkspur' por las borregas al inicio del ensayo. Los ovinos fueron acondicionados positivamente para apacentar el 'Larkspur', pero la cantidad consumida y el tiempo de consumo no fue ron suficientes para prevenit un envenenamiento potencial del ganado bovino.

PCR products and Southern blots confirmed integration of the D4E1 gene, while RT-PCR of cotton RNA confirmed the presence of D4E1 transcripts. In vitro assays with crude leaf protein extracts from T0 and T1 plants confirmed that D4E1 was expressed at sufficient levels to inhibit the growth of Fusarium verticillioides and Verticillium dahliae compared to extracts from negative control plants transformed with pBI-d35S Omega -uidA-nos (CGUS). Although in vitro assays did not show control of pre-germinated spores of Aspergillus flavus, bioassays with cotton seeds in situ or in planta, inoculated with a GFP-expressing A. flavus, indicated that the transgenic cotton seeds inhibited extensive colonization and spread by the fungus in cotyledons and seed coats. In planta assays with the fungal pathogen, Thielaviopsis basicola, which causes black root rot in cotton, showed typical symptoms such as black discoloration and constriction on hypocotyls, reduced branching of roots in CGUS negative control T1 seedlings, while transgenic T1 seedlings showed a significant reduction in disease symptoms and increased seedling fresh weight, demonstrating tolerance to the fungal pathogen. Significant advantages of synthetic peptides in developing transgenic crop plants that are resistant to diseases and mycotoxin-causing fungal pathogens are highlighted in this report.

Whereas much information is available to calculate manure production, little is known about the types and amounts of manure actually collected on typical dairy farms. This study of 54 representative Wisconsin dairy farms showed significant regional, housing, and herd size differences in collection of manure from lactating cows (Bos taurus), dry cows, and heifers. Significantly (P < 0.05) less manure is collected in the hilly southwest (56% of total annual herd production) than in the undulating south central (72%) or the flat northeast (68%) regions. Collection of lactating cow manure is significantly (P < 0.05) lower from stanchion (66% of total annual production) than free-stall (89%) housing, and significant (P < 0.05) positive relationships were found between the number of lactating cows a farm keeps and the percentage manure collected. Average annual manure N (range of 116-846 kg N ha super(-1)) and P (range of 24-158 kg P ha super(-1)) loading rates in areas where manure goes uncollected was highest in unvegetated barnyards followed by vegetated and partially vegetated outside areas. Once uncollected manure was accounted for, average annual loading rates on cereal cropland ranged from 128 to 337 kg ha super(-1) of manure N, and from 45 to 139 kg ha super(-1) of manure P. Compared with adjacent cropland, the accumulation of uncollected manure has vastly increased soil test P, K, and organic matter levels in outside areas. Manure management on Wisconsin dairy farms with small to medium herds might require assistance in managing manure in outside confinement areas to reduce the risk of impairing surface and ground water quality.

The objectives of this study were to monitor P leaching in soils with a long-term history of waste application, relate soil solution P concentrations to soil P status, and quantify P leaching losses. Soil solution was monitored for 20 mo with samplers installed at 45-, 90-, and 135-cm depths in two pits (1 x 3 x 1.5 m) in Autryville (loamy, siliceous, thermic Arenic Paleudults) and Blanton (loamy, siliceous, semiactive, thermic Grossarenic Paleudults) soils located in a grazed pasture in Sampson County, NC, which had received swine waste for >20 yr. Maximum soil solution P concentrations at 45 cm exceeded 18 mg L super(-1) in both soils. Soil solution P concentrations at 90 cm in the Blanton soil were similar to that at 45 cm indicating low P sorption. Soil solution P concentrations at 90 cm in the Autryville soil averaged 0.05 mg L super(-1) compared to 10 mg L super(-1) at 45 cm. A split-line model related soil solution P concentration to the degree of phosphorus saturation (DPS), identifying a change point at 45% DPS. Phosphorus movement past 45 cm equaled or exceeded surplus P additions for both soils. Long-term waste applications resulted in DPS > 90%, high soil solution P concentrations, and substantial vertical P movement. Phosphorus leaching should be considered when assessing long-term risk of P loss from waste-amended soils.

The Solanaceae is a large, diverse dicot family, with well-established genetic relationships between major crop species (tomato, potato, pepper, eggplant, and tobacco). Although Arabidopsis thaliana is often the model of choice for anchoring comparative studies, certain biological processes are better examined in other plants. The ripening of fleshy fruits is not tractable in Arabidopsis; however, it has received considerable attention in tomato. As a member of the Solanaceae, tomato provides a well-characterized system to anchor transcriptional profiles of fruit ripening and development in related species. By utilizing different stages of tomato, pepper, and eggplant fruit, the use of tomato microarrays for expression analysis has been demonstrated in closely related heterologous species, and groups of candidate expressed sequence tags, which are useful as orthologous markers, have been identified, as well as genes implicated in fruit ripening and development in the Solanaceae.

For acidic conditions, this finding has been attributed to limited uptake of NH super(+) sub(4) by ammonium-oxidizing bacteria (also reported herein), suggesting an advantage for direct utilization of a nonionizabie N substrate such as urea. If the same advantage applies to urea-C, nitrification of urea-N would also be promoted in neutral or alkaline soils, as reported in numerous studies. To ascertain whether urea-C can be utilized directly by nitrifying organisms, NO super(-) sub(2) production was measured for Nitrosomonas europaea and Nitrosospira sp. NPAV in minimal media with urea as the sole source of either C or C and N. Nitrite accumulated only with the latter organism, in which case nearly quantitative recovery was observed for N added as NH super(+) sub(4) and/or urea. In a subsequent study, recovery of super(14)C and super(15)N in gaseous, extractable, and hydrolyzable forms was determined after incubation with labeled urea for up to 29 days, by using two soils that differed markedly in physiochemical properties affecting nutrient availability. Results obtained in correlating super(14)C incorporation in the amino acid fraction with super(15)N accumulation as NO super(-) sub(3) were consistent with the stoichiometry that would be expected if C fixation were driven by autotrophic nitrification. Our findings demonstrate unequivocally that urea is utilized as a source of C and N by nitrifying microorganisms, which may account for rapid nitrification of urea-N soils.

H. coagulata has since greatly increased the threat of PD to the grape industry as well as stone fruit, nursery, and ornamental industries in California. This is the first in a series of articles that together describe how sharpshooter stylet penetration behaviors (especially intricate stylet activities, salivation, and ingestion) control transmission (i.e., acquisition and inoculation) of X. fastidiosa. Herein, we categorized and characterized alternating current electrical penetration graph (EPG) waveforms from glass-winged sharpshooter stylet penetration on petiole of susceptible grape ('Cabernet Sauvignon'), paying special attention to waveform fine structures that are likely to be the key to detecting the instant of inoculation. We also correlated waveforms with salivary sheath termini in grape tissues. For the first time in any EPG study of leafhopper or planthopper feeding, we demonstrate through case studies of individual probes how to follow the process of stylet penetration step by step as it is occurring, including salivary sheath branching and when the stylets first puncture a xylem cell. Finally, we discuss the implications of our findings for understanding the transmission mechanism of X. fastidiosa, in comparison with hypothesized mechanisms in the literature.

The objectives of this study were to quantify nitrate (NO sub(3)) leaching for irrigated sandy soils (Pratt loamy fine sand [sandy, mixed, mesic Lamellic Haplustalfs]) and to evaluate the effects of N fertilizer and irrigation management strategies on NO sub(3) leaching in irrigated corn. Two irrigation schedules (1.0x and 1.25x optimum) were combined with six N fertilizer treatments broadcast as NH sub(4)NO sub(3) (kg N ha super(-1)): 300 and 250 applied pre-plant; 250 applied pre-plant and sidedress; 185 applied pre-plant and sidedress; 125 applied pre-plant and sidedress; and 0. Porous-cup tensiometers and solution samplers were installed in each of the four highest N treatments. Soil solution samples were collected during the 2001 and 2002 growing seasons. Maximum corn grain yield was achieved with 125 or 185 kg N ha super(-1), regardless of the irrigation schedule (IS). The 1.25x IS exacerbated the amount of NO sub(3) leached below the 152-cm depth in the preplant N treatments, with a mean of 146 kg N ha super(-1) for the 250 and 300 kg N preplant applications compared with 12 kg N ha super(-1) for the same N treatments and 1.0x IS. With 185 kg N ha super(-1), the 1.25x IS treatment resulted in 74 kg N ha super(-1) leached compared with 10 kg N ha super(-1) for the 1.0x IS. Appropriate irrigation scheduling and N fertilizer rates are essential to improving N management practices on these sandy soils.

Ten microliters of bacterial suspensions was spot-inoculated onto cantaloupe melon rinds in pre-marked areas, and the cantaloupe melons were held at either 10 or 20C. Biofilm formation was monitored using scanning electron microscopy on excised portions of the cantaloupe melon rind at 2, 24, 48, 72 and 144 h postinoculation. Micrographs indicated that biofilm formation occurred rapidly following introduction of cells (2 h at 20C) onto the cantaloupe melon rind. A fibrillar material was visible after just 2 h at 20C, and cells were embedded in extracellular polymeric material after 24 h at either temperature. These results indicate that a human pathogen is capable of forming a biofilm on plant tissue and that biofilm formation may be responsible for the increased recalcitrance of bacteria to aqueous sanitizers.

Due to a 15-year history of spread in the Mediterranean Sea, C. taxifolia had already been placed on the US Federal Noxious Weed list in 1999. Awareness of this threat greatly facilitated consensus building and setting clear eradication goals among a large number of state, federal and local agencies as well as private groups and non-governmental organizations (NGOs) that became the 'Southern California Caulerpa Action Team' (SCCAT). Field containment and treatments began 17 days after the discovery due to: (1) timely identification and notification of the infestation; (2) the proactive staff of the San Diego Regional Water Quality Control Board who deemed this invasion tantamount to an 'oil spill', thus freeing up emergency funding; (3) the mobilization of diver crews already working at the site. Three well-integrated components of this rapid response have resulted in an effective eradication program: (a) expertise and knowledge on the biology of C. taxifolia; (b) knowledge on the uses, 'ownership' and characteristics of the infested site; (c) knowledge and experience in the implementation of aquatic plant eradication. Together, with the requisite resources (approximately $US1.2 million per year), this approach has resulted in containment, treatment and excellent progress toward eradication of C. taxifolia. Successful rapid response to other aquatic invasive species will require similar readiness to act, and immediate access to adequate funding.

Organisms tested consisted of field isolates of Paenibacillus polymyxa, Pseudomonas fluorescens, Penicillium sp., Trichoderma sp., and Rhizoctonia zeae; known biocontrol isolates including Laetisaria arvalis, Verticillium biguttatum, Cladorrhinum foecundissimum, and Stilbella aciculosa; and commercial products of Bacillus subtilis (Kodiak), Trichoderma virens (SoilGard), and T. harzianum (RootShield). Different formulations and rates of several fungal isolates and the efficacy of combinations of effective antagonists were also investigated. None of the treatments, including a chemical control (azoxystrobin), effectively controlled stem canker and black scurf in all trials. However, B. subtilis GB03, R. zeae LRNE17E, S. aciculosa 112-B, and the chemical control were most effective in reducing stem canker severity (40-49% reduction) relative to the infested controls over all trials. L. arvalis ZH-1, R. zeae LRNE17E, and the chemical control reduced black scurf severity 54-60% relative to the infested control. Other treatments also significantly reduced stem canker and black scurf, however they were slightly less effective. Biocontrol amendment rate was not correlated with disease control, although the higher rates usually provided the best control. One combination of biocontrol organisms, B. subtilis and T. virens, demonstrated somewhat better control of stem canker than each organism alone, suggesting that this approach may provide improved biocontrol efficacy.

Results indicated that the pressure in the treatment chamber responded immediately and accurately to the events of VSV. The surface temperature history, however, followed an exponential trend after saturated steam was flushed into the treatment chamber. A mathematical model was developed to simulate the surface temperature history during steam pasteurization processes. According to the model, a 5-log reduction in L. innocua inoculated onto the surface of hot dogs could be achieved using 110 C steam for 0.1 s, provided that the surface was perfectly smooth and bacteria were all distributed on the surface. However, bacteria still survived the VSV treatment even when higher temperatures were used. The incomplete destruction of bacteria on hot dog surfaces using current VSV processes may be due to the fact that the pores are filled with water and heat must penetrate into a certain depth under the surface of hot dogs in order to eliminate L. monocytogenes. This study suggested using a single long steam treatment cycle, instead of multiple short VSV cycles, for a complete destruction of bacteria hidden beneath the surface of ready-to-eat solid foods.

Escherichia coli are commonly used as indicators of fecal contamination in the environment. Despite the fact that E. coli are derived exclusively from feces or manure, effect of the presence of manure colloids on bacteria attachment to agricultural soils was never directly studied. The objective of this work was to evaluate the magnitude of the effect of manure on E. coli attachment to soil. Escherichia coli attachment to soil was studied in batch experiments with samples of loam and sandy clay loam topsoil that were taken in Pennsylvania and Maryland. Escherichia coli cells were added to the water-manure suspensions containing 0, 20, and 40 g L super(-1) of filtered liquid bovine manure, which subsequently were equilibrated with air-dry sieved soil in different soil to suspension ratios. The Langmuir isotherm equation was fitted to data. Manure dramatically affected E. coli attachment to soil. Attachment isotherms were closer to linear without manure and were strongly nonlinear in the presence of manure. The maximum E. coli attachment occurred in the absence of manure. Increasing manure content generally resulted in decreased attachment.

Unfortunately, field studies are seldom ideal. This article is one of six in this issue addressing experimental controls. Our focus is the Penobscot Experimental Forest (PEF) in Maine, where a 55-year-old experiment in northern conifer silviculture has an unreplicated, somewhat atypical control. The identification of stands that represent desired endpoints or natural states is another consideration and may be difficult if based on rare conditions. Big Reed Forest Reserve and Maine's Ecological Reserve System are discussed as possible benchmarks for management on the PEF and serve as examples of the opportunities and challenges associated with the identification of benchmark ecosystems.

Isolates that produce either, neither, or both aflatoxins and cyclopiazonic acid (CPA) are present in the field. We investigated defects in the aflatoxin gene cluster in 38 nonaflatoxigenic A. flavus isolates collected from southern United States. PCR assays using aflatoxin-gene-specific primers grouped these isolates into eight (A-H) deletion patterns. Patterns C, E, G, and H, which contain >=40kb deletions, were examined for their sequence breakpoints. Pattern C has one breakpoint in the cypA 3' untranslated region (UTR) and another in the verA coding region. Pattern E has a breakpoint in the amdA coding region and another in the ver1 5'UTR. Pattern G contains a deletion identical to the one found in pattern C and has another deletion that extends from the cypA coding region to one end of the chromosome as suggested by the presence of telomeric sequence repeats, CCCTAATGTTGA. Pattern H has a deletion of the entire aflatoxin gene cluster from the hexA coding region in the sugar utilization gene cluster to the telomeric region. Thus, deletions in the aflatoxin gene cluster among A. flavus isolates are not rare, and the patterns appear to be diverse. Genetic drift may be a driving force that is responsible for the loss of the entire aflatoxin gene cluster in nonaflatoxigenic A. flavus isolates when aflatoxins have lost their adaptive value in nature.

This places an immediate economic focus on adaptability and volume growth. However, selection for volume growth alone could result in decreased wood quality over time. Wood quality characteristics including stem straightness, wood specific gravity, and microfibril angle have either neutral or slightly unfavorable genetic correlations with volume growth in the WGFTIP loblolly pine (Pinus taeda L.) program. Since most WGFTIP members also consider wood quality an important selection criterion, the WGFTIP must define the best possible set of selection criteria given that (1) no single set of breeding objectives can be considered optimal for multiple products and (2) improvement in wood quality has no readily recognized economic importance in the existing market. To meet this challenge, the WGFTIP has implemented different strategies for its mainline breeding and deployment populations. In the mainline population, consistent breeding and selection criteria are used across members, while in the various deployment populations, selections are tailored to meet the specific needs of each member. The WGFTIP is also developing an elite wood quality population (WQEPop) based on backward selection, For the WQEPop to be successful, the economic importance of improved wood quality must be recognized, and landowners must be compensated for growing higher quality timber, especially if this results in reduced volume production. Improved methodology for within-family selection and for wood quality trait measurement is also important.

Since this bacterium is a commensal of swine, the primary goal of this study was to determine the prevalence of pathogenic Y. enterocolitica in pigs in the United Sates using feces as the sample source. A total of 2,793 fecal samples were tested for its presence in swine. Fecal samples were collected from late finisher pigs from 77 production sites in the 15 eastern and midwestern pork-producing states over a period of 27 weeks (6 September 2000 to 20 March 2001). The prevalence of ail-positive Y. enterocolitica was determined in samples using both a fluorogenic 5' nuclease PCR assay and a culture method. The mean prevalence was 13.10% (366 of 2,793 fecal samples tested) when both PCR- and culture-positive results were combined. Forty-one of 77 premises (53.25%) contained at least one fecal sample positive for the ail sequence. The PCR assay indicated a contamination rate of 12.35% (345/2,793) compared to 4.08% (114/2,793) by the culture method. Of the 345 PCR-positive samples, 252 were culture negative, while of the 114 culture-positive samples, 21 were PCR negative. Among 77 premises, the PCR assay revealed a significantly (P < 0.05) higher percentage (46.75%, n = 36 sites) of samples positive for the pathogen (ail sequence) than the culture method (22.08%, n = 17 sites). Thus, higher sensitivity, with respect to number of samples and sites identified as positive for the PCR method compared with the culture method for detecting pathogenic Y. enterocolitica, was demonstrated in this study. The results support the hypothesis that swine are a reservoir for Y. enterocolitica strains potentially pathogenic for humans.

At present, identification of this bacterium relies on isolation and biochemical testing. Although a PCR for the detection of B. avium was proposed a number of years ago (P. H. Savelkoul, L. E. de Groot, C. Boersma, I. Livey, C. J. Duggleby, B. A. van der Zeijst, and W. Gaastra, Microb. Pathog. 15:207-215, 1993), lack of analytical verification precludes its use as a diagnostic tool. Furthermore, a number of details pertaining to the reaction conditions used are missing or unclear. In the present study we have identified an optimal set of PCR conditions for use with the previously described primer pair and determined the limit of detection under these conditions to be approximately 20 pg. Assay sensitivity is 100%, based on an analysis of 72 B. avium isolates from diverse geographic locations and covering a time span of at least 25 years. Evaluation of a separate group of 87 bacterial isolates from poultry, comprising both gram-positive and gram-negative commensals and pathogens representing 11 genera, demonstrated an assay specificity of 98.8%. Reproducibility is 100% using either purified genomic DNA or boiled cell lysates less than 3 days old. Sequence analysis of the B. avium PCR amplicons identified only three occasional sequence polymorphisms. These data indicate the B. avium PCR assay can provide clinically significant results.

In fungi, these compounds are produced by large, multidomain enzymes classified as type I polyketide synthases (PKSs). In this study we identified and functionally disrupted 15 PKS genes from the genome of the filamentous fungus Gibberella zeae. Five of these genes are responsible for producing the mycotoxins zearalenone, aurofusarin, and fusarin C and the black perithecial pigment. A comprehensive expression analysis of the 15 genes revealed diverse expression patterns during grain colonization, plant colonization, sexual development, and mycelial growth. Expression of one of the PKS genes was not detected under any of 18 conditions tested. This is the first study to genetically characterize a complete set of PKS genes from a single organism.

(Euphorbiaceae), in Baja California Sur, Mexico. Immature stages are described and illustrated. Pachycoris stallii is bi- or multivoltine and occurs in xeric areas with sandy soil where it is rarely encountered away from C. californicus. Nymphs and adults feed on seeds within C. californicus fruit. Bugs oviposit on the underside of leaves, and females guard their eggs and first-instar nymphs from natural enemies. Embryonic orientation of prolarvae is nonrandom; each embryo is oriented with its venter directed toward the ground. This orientation may facilitate aggregation of first instars. The longitudinal axes of eggs are always oriented upward at about a 16 degree angle of deviation from a line perpendicular to the leaf surface. This is the first recorded observation of this phenomenon in Pentatomoidea. Experimental removal of females guarding first instars results in 100% loss of nymphs, and this is attributed to disruption of the aggregative behavior of nymphs. Maternal guarding appears to be a net benefit to P. stallii, despite possible costs to the brooding female.

A 1-year wheat cover crop consisting of three short-term cropping periods with plant material removed at the end of each growth period and a 3-year B. napus green manure significantly enhanced vegetative growth and yield of Gala/M26. However, in each instance, the resulting disease control and growth response were inferior to that achieved through preplant methyl bromide soil fumigation. A 3-year bare fallow and 1- or 2-year B. napus green manure neither suppressed disease development nor enhanced tree growth. Preplant RSM amendment in conjunction with a postplant mefenoxam soil drench provided effective suppression of ARD, and the resulting tree growth and yield were comparable with that attained in response to 1,3-dichloropropene-chloropicrin fumigation in one orchard. At a second orchard, the growth response attained with the alternative treatment was inferior to preplant soil fumigation, which was associated with an apparent re-infestation of RSM-treated soils and tree roots by Pratylenchus spp. Application of RSM after wheat cropping or in conjunction with soil solarization provided an intermediate level of disease control and a corresponding reduction in growth and yield of apple relative to preplant fumigation at both sites.

In a field study, population levels of race 1 decreased relative to race 0 when cultivars with partial resistance to both races were planted, suggesting that race 1 isolates were less fit than race 0 isolates. Experiments were conducted to quantify differences in aggressiveness and survivability of the two races. Tobacco varieties with low, moderate, or high levels of partial resistance were inoculated with 60 pathogen isolates, and symptom development was monitored for 3 weeks. Race 0 isolates were more aggressive than race 1 isolates on cultivars with moderate or high levels of partial resistance; incubation periods were shorter and root rot severity was greater with race 0 isolates. Isolates of race 1, however, caused greater stunting of plants with moderate and high levels of partial resistance than race 0 isolates. Field microplots were infested with either a single race or an equal mixture of each race. Soil samples were collected at the end of two growing seasons and again the following spring. Pathogen populations declined from 40 to 80% during winter months, but population declines for race 0 were lower than for race 1 in each treatment over each winter. Race shifts from race 1 to race 0 that were observed in the presence of cultivars with partial resistance appear to be primarily the result of differences in aggressiveness of the races, with a possible minor effect of enhanced overwintering survival of race 0 compared with race 1.

Single uredinial isolates (580 in total) were derived from the wheat leaf rust collections and tested for virulence phenotype on lines of Thatcher wheat that are near-isogenic for leaf rust resistance genes Lr1, Lr2a, Lr2c, Lr3, Lr9, Lr16, Lr24, Lr26, Lr3ka, Lr11, Lr17, Lr30, LrB, Lr10, Lr14a, and Lr18. In the United States in 2003, 52 virulence phenotypes of P. triticina were found. Virulence phenotype MBDS, which has been selected by virulence to resistance gene Lr17, was the most common phenotype in the United States. MBDS was found in the Southeast, Great Plains, the Ohio Valley, and California. Virulence phenotype THBJ, which has been selected by virulence to genes Lr16 and Lr26, was the second most common phenotype, and was found in the southern and northern central Great Plains region. Phenotype MCDS, which has been selected by virulence to genes Lr17 and Lr26, was the third most common phenotype and occurred in the same regions as MBDS. The use of wheat cultivars with leaf rust seedling resistance genes has selected leaf rust phenotypes with virulence to genes Lr9, Lr16, Lr17, Lr24, and Lr26. The population of P. triticina in the United States is highly diverse for virulence phenotypes, which will continue to present a challenge for the development of wheat cultivars with effective durable resistance.

The disease poses a health risk to humans and livestock because of the associated production of the mycotoxin deoxynivalenol (DON or vomitoxin) by the causal organism, Fusarium gmminearum. A study was undertaken to examine the efficiency of high-speed, optical sorting of intact wheat (Triticum aestivum) kernels for reduction of DON concentration. Soft red winter (n = 32) and soft white (n = 3) wheat samples, known to have elevated levels of FHB, were obtained from commercial mills throughout the eastern United States. An additional seven samples of wheat from the discard piles of in-mill cleaners were also studied. Fusarium-damaged wheat, cleaned of nonkernels and foreign material ( similar to 4.5 kg/sample, DON range = 0.6 to 20 mg/kg), was fed into a commercial high-speed bichromatic sorter operating at a throughput of 0.33 kg/(channel-min) and a kernel rejection rate of 10%. A wavelength filter pair combination of 675 and 1,480 nm was selected for sorting, based on prior research. Visual measurements of the proportion of Fusarium-damaged kernels were collected on incoming and sorted seed (separate analyses of accepted and rejected portions), as were measurements of DON concentration. Results indicated that the fraction of DON contaminant level in the sorted wheat to that in the unsorted wheat ranged from 18 to 112%, with an average of 51%. Nine of the 35 regular samples and all seven of the discard pile samples underwent a second sort, with five from this second set undergoing a third sort. Multiple sorting was effective in producing wheat whose DON concentration was between 16 and 69% of its original, unsorted value.

Considerable variation in disease severity across the affected area often has been noted. We investigated the influence of site microclimate on fungal colonization as a basis for this variation with a combination of seedling inoculation and field studies. Development of P. gaeumannii ascocarps on inoculated seedlings subjected to mist, irrigation, and shading treatments was followed for 10 months. Contrary to expectations, numbers of ascocarps on foliage were negatively correlated with shade and mist and positively correlated with temperature. Numbers of ascocarps on foliage, site temperature, and leaf wetness were monitored over 5 years at nine field sites in the Oregon Coast Range. Factors most highly correlated with ascocarp abundance were winter mean daily temperature and spring cumulative leaf wetness. Predictive models for disease severity on the basis of these correlations were tested against disease and climate data measured at field sites during 2003-2004. A temperature-based disease prediction model was developed in combination with geographical information systems (GIS)-linked climate databases to estimate disease levels across a portion of the Oregon Coast Range. This model can be used for hypothesis testing and as a decision support tool for forest managers.

In this study, a real-time PCR for AlHV-1 DNA was developed and compared to an established nested PCR. The nested PCR amplifies a region of the AlHV-1 gene coding for a transactivator protein (ORF 50), while the real-time PCR assay targets the AlHV-1 gene coding for a tegument protein (ORF 3). The real-time PCR assay reproducibly detected 10 copies of target DNA. In a dilution series of the target DNA there was linearity of the assay across 8 orders of magnitude (10 super(1)-10 super(9) copies). The nested PCR was more sensitive ( approximately equal to 1log) than the real-time PCR. The assay specifically amplified samples containing only AlHV-1, but not other common herpesviruses of cattle. In conclusion, we have developed a rapid, relatively sensitive, and reliable real-time PCR assay specific for AlHV-1. Similar to the real-time PCR for Ovine herpesvirus-2, this assay should prove useful for differential diagnostics of clinical MCF and for research to better define the epidemiology of AlHV-1 in wildebeest as well as in animals with wildebeest-associated MCF.

A recently developed field portable multispectral fluorescence imaging system was used to acquire steady-state fluorescence images of feces contaminated apples. Twenty Red Delicious apples encompassing natural color variation were artificially contaminated with dairy cow feces to create five fecal contamination spots on each apple. The feces spots were not clearly visible to the human eye. Multispectral fluorescence images, with wavebands centered at the red emission peaks of cow feces and apples, in addition to blue and green bands, were evaluated to determine an optimal red band for detection of feces contamination spots on apples. The results show that fluorescence emission bands at 670 nm provided the greatest potential for the detection of feces contamination on apples. In addition, investigation of multispectral fusion methods indicated that band ratio image of 670 nm to 450 nm or 550 nm improve sensitivity of detection. Two-band ratios along with the use of unsupervised histogram-based thresholding allowed detection of cow feces contaminations on apples regardless of apple colorations with a 100% success rate.

Longevity is determined by interactions of humidity, temperature, and unknown cellular factors that affect the propensity for damaging reactions. Here we describe our research to elucidate those cellular factors and to ultimately predict how long a population can survive under extreme conditions. Loss of viability typically follows a sigmoidal pattern, where a period of small changes precedes a cataclysmic decline. The time for viability to decrease to 50% (P50) varied among seed species and among 10 phylogenetically diverse organisms. When stored at elevated temperatures of 35 degree C and 32% relative humidity (RH), P50 ranged from about a week for spores of Serratia marcescens to several years for fronds of Selaginella lepidophylla. Most of the species studied survived longest at low humidity (10-20% RH), but suffered under complete dryness. Temperature dependencies of aging kinetics appeared similar among diverse organisms despite the disparate longevities. The effect of temperature on seed aging rates was consistent with the temperature dependency of molecular mobility of aqueous glasses, with both showing a reduction by several orders of magnitude when seeds were cooled from 60 degree C to 0 degree C. Longevity is an inherited trait in seeds, but its complex expression among widely divergent taxa suggests that it developed through multiple pathways.

AN - 17470200; 6656848 AB - Bryophytes are a non-monophyletic group of three major lineages (liverworts, hornworts, and mosses) that descend from the earliest branching events in the phylogeny of land plants. We postulate that desiccation tolerance is a primitive trait, thus mechanisms by which the first land plants achieved tolerance may be reflected in how extant desiccation-tolerant bryophytes survive drying. Evidence is consistent with extant bryophytes employing a tolerance strategy of constitutive cellular protection coupled with induction of a recovery/repair mechanism upon rehydration. Cellular structures appear intact in the desiccated state but are disrupted by rapid uptake of water upon rehydration, but cellular integrity is rapidly regained. The photosynthetic machinery appears to be protected such that photosynthetic activity recovers quickly. Gene expression responds following rehydration and not during drying. Gene expression is translationally controlled and results in the synthesis of a number of proteins, collectively called rehydrins. Some prominent rehydrins are similar to Late Embryogenesis Abundant (LEA) proteins, classically ascribed a protection function during desiccation. The role of LEA proteins in a rehydrating system is unknown but data indicates a function in stabilization and reconstitution of membranes. Phylogenetic studies using a Tortula ruralis LEA-like rehydrin led to a re-examination of the evolution of desiccation tolerance. A new phylogenetic analysis suggests that: (i) the basic mechanisms of tolerance seen in modern day bryophytes have changed little from the earliest manifestations of desiccation tolerance in land plants, and (ii) vegetative desiccation tolerance in the early land plants may have evolved from a mechanism present first in spores.

Study sites were treated with aerial applications of tebuthiuron (N-[5-(1,1-dimethylethyl)-1,3,4-thiadiazol-2-yl]-N,N'-dimethylurea ) as part of a brush control program administered by the US Bureau of Land Management. Study sites were equally distributed among 3 geographic regions and included 6 sites treated 5-9 years ago, 6 sites treated 15-18 years ago, and 12 contiguous nontreated sites. Paired 1-m super(2) rainfall simulation plots encompassed the creosotebush canopy zone and adjacent interspace area with runs made using simulated rainfall at 9.1 cm.hr super(-1) for 30 minutes. Runoff and sediment were collected every 5 minutes, and wetting-front depths were measured at the end of rainfall simulations. Infiltration rates were significantly higher in the canopy zone than in interspace areas and were highest in 5-9-year-old sites, intermediate in nontreated sites, and lowest in 15-18-year-old sites. Regression equations showed that infiltration rates within the canopy zone were positively correlated with litter mass, and cover of litter, shrubs, and grasses. Within interspace areas, infiltration rates were most correlated with aggregate stability and cover of litter, rocks, and grasses. Wetting-front depths were significantly deeper in the canopy zone than in interspace areas for all treatments. Sediment concentration (kg.L super(-1)) was higher in the canopy zone than interspace, but total sediment yield was not significantly different between these areas or affected by any treatments.Original Abstract: Se examinaron los efectos del control quimico del 'Creosotebush' (Larrea tridentata (D.C.) Cov.) sobre las tasas de infiltracion, profundidad del frente humedo y produccion de sedimentos en el Desierto Chihuahuense del Sur de Nuevo Mexico. Los sitios de estudio se trataron con aplicaciones aereas de tebuthiuron (N-[5-(1,1-dimetiletil)-1,3,4-tiadiazol-2-yl]-N,N'-dimetilurea) como parte de un programa de control de arbustos administrado pro el Buro de Manejo de Tierras de EE.UU. Los sitios de estudio fuero distribuidos equitativamente entre 3 regiones geograficas e incluyeron 6 sitios tratados 5-9 anos antes, 6 sitios tratados 15-18 anos antes y 12 sitios contiguos no tratados. Se Usaron parcelas apareadas de 1 m super(2) para simulacion de lluvia que abarcaron la zona de la copa del 'Creosotebush' y el area del espacio entre plantas adyacente y se hicieron corridas usando lluvia simulada a razon de 9.1 cm.hr super(-1) por 30 minutes. El escurrimiento y los sedimentos fueron colectados cada 5 minutos y las profundidades del frente humedo fueron medidas al final de las simulaciones de lluvia. Las tasas de infiltracion fueron significativamente mayores en la zona de la copa que en el area del espacio entre plantas y las mayores tasas fueron en los sitios con 5-9 anos de haber sido tratados y las menores en los sitios con 15-18 anos de antigueedad. Las ecuaciones de regresion mostraron que las tasas de infiltracion dentro de la zona de la copa estuvieron positivamente correlacionadas con la masa de mantillo, arbustos y zacates. En las areas entre plantas las tasas de infiltracion estuvieron mas correlacionadas con la estabilidad de los agregados y cobertura de mantillo, rocas y zacates. Las profundidades del frente humedo fueron significativamente mas profundas en la zona de la copa que en las areas entre plantas, esto fue igual en todos los tratamientos. La concentracion de sedimentos (kg.L super(-1)) fue mayor en la zona de la copa que en el area entre plantas, pero el rendimiento total de sedimentos no fue significativamente diferente entre estas areas o las afectadas por cualquiera de los tratamientos.

Grazing may provide an alternative to chemical and mechanical control of perennial pepperweed. However, if livestock are used in control efforts, they may spread weeds by depositing viable seeds in fecal pats in uninfested areas. This study consisted of 2 experiments using fistulated steers to estimate the effect of ruminant digestion on germination of perennial pepperweed seeds. In Experiment 1, we tested the hypothesis that ruminal incubation (for 0, 48, and 96 hours) affects perennial pepperweed germination. In Experiment 2, we tested the hypothesis that type of incubation (no incubation, water only, or total digestive tract) affects perennial pepperweed germination. In Experiment 1, germination was 17 and 15 times greater for the 48- and 96-hour incubation treatments compared to the control, respectively. In Experiment 2, germination was 23 and 19 times greater for the water and total tract incubation treatments compared to the control, respectively. Effects were attributed to a combination of seed hydration and seed coat scarification. Results from this study suggest that grazing should occur prior to seed set or that livestock which have grazed perennial pepperweed bearing viable seed should be quarantined before being moved to uninfested areas. These results also suggest that control of perennial pepperweed is especially important where moving water may transport seeds off site.Original Abstract: El 'Perennial pepperweed' (Lepidium latifolium L.) es una hierba perenne agresiva que esta infestando muchas areas de Norteamerica. El apacentamiento puede ser una alternativa del control quimico y mecanico del 'Perennial pepperweed,' sin embargo, si el ganado es usado para el control de malezas, este puede dispersar semillas de ellas al depositar en areas sin infestar heces fecales conteniendo semillas viables de malezas. Este estudio consistio de dos experimentos usando novillos fistulados para estimar el efecto de la digestion ruminal en la germinacion de semillas de 'Perennial pepperweed.' En el experimento 1 probamos la hipotesis que la incubacion ruminal (0, 48, y 96 hora) afecta la germinacion de las semillas de 'Perennial pepperweed' y en el experimento 2 probamos la hipotesis de que el tipo de incubacion (sin incubar, solo agua y el paso, a traves del tracto digestivo) tambien afecta la germinacion de las semillas de esta especie. En el experimento 1, a las 48 y 96 horas, la germinacion fue 17 y 15 veces mayor que la del control respectivamente. En el experimento 2, la germinacion fue 23 y 19 veces mayor para los tratamientos de agua y paso a traves del tracto digestivo, respectivamente, en comparacion con el tratamiento control. Los efectos fueron a atribuidos a una combinacion de hidratacion de la semilla y la escarificacion de la cubierta de ella. Los resultados de este estudio sugieren que el apacentamiento puede ocurrir antes de la produccion de semilla o que el ganado que ha apacentado el 'Perennial pepperweed,' y tiene semillas viables en el tracto digestivo, debe ser cuarentenado antes de ser movido a areas sin infestar. Estos resultados tambien sugieren que el control del 'Perennial pepperweed' es especialmente importante donde las aguas en movimiento puede transportar las semillas de esta especie fuera de sitios infestados.

The data would be used as baseline information for reducing A. niger contamination in insect artificial diets. Methods and Results:Aspergillus niger was isolated from an insect artificial diet. Four concentration levels (i.e. 0, 1, 10 and 20 mu mol) of two fungicides (i.e. amphotericin B and itraconazole) were tested against A. niger under four a sub(w) levels (i.e. 0.994, 0.961, 0.921 and 0.859) adjusted by including 0, 12.5, 25 and 38% of glycerol in the medium mixture. Aspergillus niger growth was significantly reduced at low fungicide concentration (1 mu mol), and at reduced a sub(w). The spore germination was prevented with either higher fungicide concentration (>10 mu mol), or low a sub(w) in the medium (a sub(w) < 0.921). The two ecological determinants (fungicides and a sub(w)) showed a significant impact on A. niger survival in the medium (P < 0.0001). Itraconazole is more effective than amphotericin B in controlling A. niger contamination in the agar medium. Conclusion:Adjustment of a sub(w) (with 12.5% of glycerol) in combination with 1 mu mol of itraconazole can effectively prevent A. niger growth in the SDA cultural medium. Significance and Impact of the Study:Aspergillus niger contaminations have frequently affected the quality of insects produced from mass rearing facilities. Low a sub(w) in combination with low fungicide concentration has the potential to become one of the most cost-effective management strategies to prevent A. niger contamination in insect artificial diets. The effect of fungicides and low a sub(w) in artificial diets on insect biology needs to be further examined.

Based on morphological and biochemical criteria, the strains were tentatively identified as belonging to the genus Bacteroides but they did not appear to correspond to any recognized species of the genus. Comparative 16S rRNA gene sequencing studies showed that the strains were related closely to each other and confirmed their placement in the genus Bacteroides, but sequence divergence values of >10 % from reference Bacteroides species demonstrated that the organisms from manure represent a novel species. Based on biochemical criteria and molecular genetic evidence, it is proposed that the unknown isolates from manure be assigned to a novel species of the genus Bacteroides, as Bacteroides coprosuis sp. nov. The type strain is PC139 super(T) (=CCUG 50528 super(T)=NRRL B-41113 super(T)). Published online ahead of print on 12 August 2005 as DOI 10.1099/ijs.0.63869-0.

A comprehensive description of the process and parameters used for calibrating the Root Zone Water Quality Model, v. 1.3.2004.213, is presented in this article. The model was calibrated to simulate tile drainage and leached nitrate under conventional tillage management practices for maize (Zea mays L.) production followed by a rye (Secale cereale L.) cover crop in Cecil soils (kaolinitic, thermic, Typic Kanhapludults), and for cotton (Gossypium hirsutum L.) development in the Georgia Piedmont. Tile drainage and nitrate leaching were simulated within 15% of the observed values in the calibrated maize scenarios with and without the soil macroporosity option. Simulated and observed tile drainage and leached nitrate were not significantly different, and the simulated values were not significantly different with and without the macroporosity option. Simulated cotton biomass and leaf area index were well correlated with observed biomass and leaf area index until the last 21 d of the reproductive stage. Simulated and observed cotton water use were different by <1 mm d super(-1) based on [Delta] soil water in a 60-cm profile during the critical peak bloom period. A detailed analysis of the calibration procedure and parameters used in this study will aid subsequent users of the model as well as aid in a subsequent evaluation of the model's performance for simulations of tile drainage and nitrate leaching in Georgia Piedmont cotton production systems.

The African members of the subgenus form a series of lineages basal to a monophyletic neotropical species radiation. The neotropical species have large, showy flowers visited by either euglossine bees or hummingbirds. The hummingbird pollination syndrome is supported as a derived character state from the bee pollination syndrome, and we estimate that it has evolved independently seven or more times in the neotropics. A molecular clock approach suggests that diversification of the neotropical clade has been recent and rapid and that it coincides with dramatic climatic and geologic changes, Andean orogeny, and the closing of the Panama isthmus that occurred in the Pliocene and Pleistocene epochs. We propose a scenario for the diversification of Costus, in which rapid floral adaptation in geographic isolation and range shifts in response to environmental changes contribute to reproductive isolation among close relatives. We suggest that these processes may be common in other recently diversified plant lineages centered in Central America or the Northern Andean phytogeographic region.

DNA polymorphism within cultivated tomato has been estimated to be low based on molecular markers. Through mining of more than 148,000 public tomato expressed sequence tags (ESTs) and full-length cDNAs, we identified 764 EST clusters with potential single nucleotide polymorphisms (SNPs) among more than 15 tomato lines. By sequencing regions from 53 of these clusters in two to three lines, we discovered a wealth of nucleotide polymorphism (62 SNPs and 12 indels in 21 Unigenes), resulting in a verification rate of 27.2% (28 of 103 SNPs predicted in EST clusters were verified). We hypothesize that five regions with 1.6-13-fold more diversity relative to other tested regions are associated with introgressions from wild relatives. Identifying polymorphic, expressed genes in the tomato genome will be useful for both tomato improvement and germplasm conservation.

The enzyme was purified to homogeneity by (NH sub(4)) sub(2)SO sub(4) fractionation, anion exchange and affinity chromatography. The protein had a correct N-terminal sequence of WAQSSVIDAYVAS, indicating that the signal peptide was efficiently cleaved. The recombinant enzyme was glycosylated with a 2.4% carbohydrate content. It had a pH optimum of 4.6 and a pH 3.4-6.4 stability range. The temperature optimum was 50 degree C with stability less than or equal to 50 degree C. The enzyme showed considerable loss of activity when incubated with glucose (44%), glucosamine (68%), galactose (22%), and xylose (64%). The addition of Mn super(++) activated the enzyme by 45%, while Li super(+), Zn super(+)+, Mg super(++), Cu super(+), Ca super(++), and EDTA had no effect. The enzyme hydrolyzed amylopectin at rates 1.5 and 8.0 times that of soluble starch and amylose, respectively. Soluble starch was hydrolyzed 16 and 29 times faster than wheat and corn starch granules, respectively, with the hydrolysis of starch granules using 10x the amount of GLA. Apparent K sub(m) and V sub(max) for soluble starch were estimated to be 3.0 mg/ml and 0.13 mg/ml/min (40 degree C, pH 5.3), with an apparent k sub(cat) of 2.9x 10 super(5) min super(-1).

We tested the phosphate removal capacity of juniper fiber through isotherm, kinetic, column, and field tests. Heavy metals from an acid mine drainage (AMD) site were precipitated on the surface of juniper fiber. The modified fiber was tested in laboratory-scaled batch and column tests. Elemental analysis showed that soluble iron species deposited on the modified fiber acted as an inorganic adsorbent for anions; sorption capacity of this juniper fiber was higher than that of other conventional adsorbents. A pseudo second-order kinetic model fitted well for sorption of phosphorus onto the modified medium. The modified lignocellulosic material was used to remove phosphorus from wastewater from two dairy farms in the Catskill/Delaware watershed. The fiber was installed inside a filter box, forming a nonwoven mat. Phosphorus removal efficiency of the material was about 41 percent at 59 mg/L of influent phosphorus concentration.

6758319 AB - Dying-arm disease in grapevines, produced by infection with the ascomycete Eutypa lata, is responsible for major production losses in vineyards. Dieback of the shoots and cordon is believed to be due to acetylenic phenol metabolites produced by the fungus. To identify specific metabolites that could potentially be used for diagnosis of infection, eight E. lata isolates were grown in vitro on hot water extracts from grape varieties with various degrees of tolerance to the foliar symptoms of E. lata dieback. HPLC analysis showed that eutypinol was consistently produced in large amounts, together with smaller amounts of methyleutypinol and eulatachromene; eutypine, the putative toxin, was produced solely on Sauvignon Blanc extract and then in only barely detectable amounts. When E. lata isolates from Cabernet Sauvignon and Merlot were grown on identical media, the amounts of metabolites produced differed significantly between isolates but the pattern of metabolites was quite similar, with eutypinol again predominating. The consistent production of eutypinol indicated that this was the most suitable metabolite for which to analyze in order to diagnose the presence of E. lata. Extraction and analysis of grapevine tissues exhibiting symptoms of dieback failed to show the presence of any metabolites. However, when infected cordon sections were placed in water and cultured for 5 days, eutypinol was readily detected in the aqueous solution; metabolites were not produced from uninfected tissue. This provides a method for detection of infected tissue and indicates that the toxic metabolites react at the point of production, disrupting the vascular structure and inhibiting transport of nutrients, rather than being translocated to tissues that exhibit symptoms.

Consequently, these species may benefit the most by entering new habits to escape their natural enemies. This hypothesis predicts that high- resource invasive species may be particularly susceptible to biological control and that increases in resource availability will favor exotic plants.

AN - 68638972; 16190626 AB - Bioassay-guided fractionation of the hexane/ethyl acetate/water (H/EtOAc/H2O) crude extract of the aerial parts of Haplophyllum sieversii was performed because of preliminary screening data that indicated the presence of growth inhibitory components against Colletotrichum fragariae, Colletotrichum gloeosporioides, and Colletotrichum acutatum. Fractionation was directed using bioautographical methods resulting in the isolation of the bioactive alkaloids flindersine, anhydroevoxine, haplamine, and a lignan eudesmin. These four compounds were evaluated for activity against C. fragariae, C. gloeosporioides, C. acutatum, Botrytis cinerea, Fusarium oxysporum, and Phomopsis obscurans in a dose-response growth-inhibitory bioassay at 50.0, 100.0, and 150.0 microM. Of the four compounds tested, flindersine demonstrated the highest level of antifungal activity. Additionally, flindersine, eudesmin, and haplamine were screened against the freshwater phytoplanktons Oscillatoria perornata, Oscillatoria agardhii, Selenastrum capricornutum, and Pseudanabaena sp. (strain LW397). Haplamine demonstrated selective inhibition against the odor-producing cyanobacterium O. perornata compared to the activity against the green alga S. capricornutum, with lowest observed effect concentration values of 1.0 and 10.0 microM, respectively.

AN - 69071837; 16419752 AB - The prevalence of viable Toxoplasma gondii was determined in 6,282 samples (2,094 each of beef, chicken, and pork) obtained from 698 retail meat stores from 28 major geographic areas of the United States. Each sample consisted of a minimum of 1 kg of meat purchased from the retail meat case. To detect viable T. gondii, meat samples were fed to T. gondii-free cats and feces of cats were examined for oocyst shedding. Initially, 100 g of meat from 6 individual samples of a given species were pooled (total, 600 g), fed to a cat over a period of 3 days, and feces were examined for oocysts for 14 days; the remaining meat samples were stored at 4 C for 14 days (until results of the initial cat fecal examination were known). When a cat fed pooled samples had shed oocysts, 6 individual meat samples from each pool were bioassayed for T. gondii in cats and mice. Toxoplasma gondii isolates were then genetically characterized using the SAG2 locus and 5 hypervariable microsatellite loci. In all, 7 cats fed pooled pork samples shed oocysts. Toxoplasma gondii oocysts were detected microscopically in the feces of 2 of the cats; 1 isolate was Type II and the second was Type III. Analyzed individually, T. gondii was detected by bioassay in 3 of the 12 associated samples with genetic data indicating T. gondii isolates present in 2. The remaining 5 pooled pork samples had so few oocysts that they were not initially detected by microscopic examination, but rather by mouse bioassay of cat feces. Two were Type I, 1 was Type II, and 2 were Type III. None of the cats fed chicken or beef samples shed oocysts. Overall, the prevalence of viable T. gondii in retail meat was very low. Nevertheless, consumers, especially pregnant women, should be aware that they can acquire T. gondii infection from ingestion of undercooked meat, and in particular, pork.

AN - 68876010; 16335135 AB - A study was conducted to investigate the microbiological impact of spray washing broiler carcasses with chlorinated water (0 or 50 ppm) at different temperatures (21.1, 43.3, or 54.4 degrees C). A whole carcass rinse (WCR) was performed on each carcass before (control) and after spray washing (final). After the control WCR, carcasses were inoculated with 0.1 g of cecal material containing 2 x 10(5) cells per gram of Campylobacter and 2 x 10(5) cells per gram of nalidixic acid-resistant Salmonella. Carcasses were held at room temperature for 12 min before washing in an inside-outside bird washer (80 psi for 5 s). Chlorine level and water temperature had no effect on total aerobic bacteria, Escherichia coli, or Campylobacter numbers recovered from the final WCR. Levels of bacteria found on carcasses before and after washing were 4.6, 3.6, and 3.5 log10 cfu/mL rinse for total aerobic bacteria, E. coli, and Campylobacter, respectively. Average counts for nalidixic acid-resistant Salmonella after washing were 3.1 log10 cfu/ mL rinse irrespective of water temperature or chlorine level (P < 0.05). In addition, chlorine level and water temperature had no effect on the breast skin color, with average values of L* = 66.6; a* = -0.09; b* = -0.05 (P < 0.05). Under the conditions outlined in the present study, adding chlorine and/or elevating the water temperature during spray washing in an inside-outside bird washer did not enhance the removal of bacteria from broiler carcasses and had no effect on carcass skin color.

AN - 68874498; 16334336 AB - Effects of different concentrations of GF-120 NF Naturalyte Fruit Fly Bait on attraction and feeding responses, mortality, and control of the western cherry fruit fly, Rhagoletis indifferens Curran, were determined. In the laboratory, flies that had been exposed to sugar and yeast extract and then deprived of all food for 16-20 h were attracted to 40.0% GF-120, but not to 0.6 and 4.8% GF-120 (vol:vol). Nonstarved flies were not attracted to any concentration. Flies in the field were not attracted to 55.6% GF-120 on cherry leaves, and few flies fed on the bait. In the laboratory, males fed for shorter durations on and ingested lower amounts of 0.6% than 4.8 or 40.0% GF-120, but females fed equally on all concentrations. Spinosad in GF-120 was highly toxic to flies. Lethal concentrations50 (LC50 values) of spinosad for starved flies at 1-4 d were 1.5-0.7 ppm. When gravid flies were exposed to cherries treated with 0.6, 4.8, and 40.0% GF-120, mortality was greater at each higher concentration, but none prevented oviposition. Field spray tests comparing 0.6, 4.8, and 40.0% GF-120 in 225 ml of spray per cherry tree resulted in 79-94% lower larval infestations than in controls, but no differences were seen among the concentrations. Evidence from this study indicates that fresh 40.0% GF-120 was attractive in the laboratory but that flies were not attracted to fresh GF-120 from far distances within trees, suggesting that suppression of populations is caused in large part by flies finding the bait through normal movement over large areas.

AN - 68872764; 16334332 AB - The effects of tomato, Lycopersicum spp., leaves treated with imidacloprid on probing and settling behavior of Frankliniella fusca (Hinds) and Frankliniella occidentalis (Pergrande) were examined using an electrical penetration graph technique and an intact leaf bioassay. For each experiment, thrips were subjected to nontreated plants and plants treated with either of two rates of imidacloprid: 7.81 and 41.55 microg [(AI)] per plant. F. fusca probed less frequently on plants treated with the high rate of imidacloprid compared with the nontreated plants. The duration of F. fusca noningestion probing waveforms and ingestion was shorter on plants treated with the high rate of imidacloprid compared with that on nontreated plants. In contrast, F. occidentalis probed longer and more frequently on plants treated with either the low or high imidacloprid rates compared with nontreated plants. They also ingested more frequently and for longer durations on plants treated with the high rate compared with nontreated plants. The duration and frequency of noningesting probing waveforms were greater on the imidacloprid-treated plants compared with the nontreated plants. F. occidentalis probed and ingested more frequently and for a longer duration than F. fusca on plants treated with the high rate of imidacloprid. F. fusca ingested more frequently and the duration of ingestion was longer than F. occidentalis in untreated plants. F. fusca and F. occidentalis settling behavior differed within the first 30 min in a choice bioassay. F. fusca preferred settling on leaves of nontreated plants, whereas F. occidentalis showed no preference in an intact leaf choice bioassay.

AN - 68871196; 16334331 AB - The efficacy of verbenone as a stand-level protectant against mountain pine beetle, Dendroctonus ponderosae Hopkins, attacks was tested in lodgepole and whitebark pine stands at five geographically separated sites, including three consecutive years at one site. Forty and 20 high-dose pouches, with a verbenone emission rate up to 50 mg/d per pouch, were spaced in a grid pattern throughout 0.40-ha plots, replicated up to six times at each site. Although the verbenone treatment did not prevent beetles from dispersing through treated stands, attacking large-diameter trees most frequently, the overall number of trees attacked was, on average, reduced significantly compared with nontreated stands. In a few blocks each year, verbenone-treated plots had more attacked trees than controls. These blocks tended to have a large emerging beetle population, exceeding 140 previously attacked trees within the hectare including and surrounding the treated area. Additional research is needed on the behavioral role of verbenone in mountain pine beetle population dynamics and quantification of the infestation level above which treatment efficacy tends to be reduced.

All insects were placed on diet immediately after hatching and observed until death or pupation occurred. At a concentration of 10 ppm, avidin had little or no effect on growth and mortality compared with the control. However at a concentration of 100 ppm almost all tested insects were killed. H. zea was further tested by adding sublethal concentrations of Bt (CrylAc) in the diet containing avidin. The synergistic effect was significant, with mortality increasing to 44.4% over additive mortality (21.6%) of Bt and avidin.

AN - 68864356; 16334323 AB - Amulet C-L (cue-lure) and Amulet ME (methyl eugenol) molded paper fiber "attract-and-kill" dispensers containing fipronil were tested under Hawaiian weather conditions against Bactrocera cucurbitae (Coquillett) (melon fly) and Bactrocera dorsalis (Hendel) (oriental fruit fly), respectively. In paired tests (fresh versus weathered), C-L dispensers were effective for at least 77 d, whereas ME dispensers were effective for at least 21 d. Thus, C-L dispensers exceeded, whereas ME dispensers did not meet the label interval replacement recommendation of 60 d. Addition of 4 ml of ME to 56-d-old ME dispensers restored attraction and kill for an additional 21 d. This result suggested the fipronil added at manufacture was still effective. By enclosing and weathering ME dispensers inside small plastic bucket traps, longevity of ME dispensers was extended up to 56 d. Fipronil ME and C-L dispensers also were compared, inside bucket traps, to other toxicants: spinosad, naled, DDVP, malathion, and permethrin. Against B. dorsalis, fipronil ME dispensers compared favorably only up to 3 wk. Against B. cucurbitae, fipronil C-L dispensers compared favorably for at least 15 wk. Our results suggest that fipronil C-L dispensers can potentially be used in Hawaii; however, fipronil ME dispensers need to be modified or protected from the effects of weathering to extend longevity and meet label specifications. Nonetheless, Amulet C-L and ME dispensers are novel prepackaged formulations containing C-L or ME and fipronil that are more convenient and safer to handle than current liquid insecticide formulations used for areawide suppression of B. dorsalis and B. cucurbitae in Hawaii.

AN - 68726476; 16245704 AB - Shell quality has been identified as a heritable trait that can be manipulated by genetic selection. Previous research has concluded that many methods of determining shell quality produce variable results. With the development of newer, more precise measuring technologies, shell strength can now be assessed in a consistent, objective fashion. A research project was conducted to determine what role shell strength might play in affecting external Salmonella Enteritidis contamination of egg contents. Visibly clean eggs were collected from an in-line shell egg-processing facility at the accumulator. Eggs were inoculated by dipping in a concentrated suspension of nalidixic acid-resistant Salmonella Enteritidis. After storage, eggs were assessed for shell strength and both external and internal Salmonella Enteritidis contamination. In the first study, there was a significant difference (P < 0.05) in shell strength among the three replicates. No differences between treatments were found for shell strength or Salmonella Enteritidis contamination of contents. In the second study, there were no replicate differences for any of the monitored factors. When rinsate and content samples were enriched, 100% of the rinsates were positive for Salmonella Enteritidis. No content samples were shown to be contaminated with Salmonella Enteritidis during direct plating, but 3 to 5% of the samples from each replicate were positive after enrichment. Correlation analysis of the results from each study found only weak correlations between shell strength and Salmonella Enteritidis contamination on eggshell surface or contents. Within the range of shell strengths recorded in this study, the correlation analysis suggests that shell strength does not play a major role in Salmonella Enteritidis contamination. Further work with eggs that represent a greater range of shell strengths could provide a clearer indication of the interaction of shell strength and Salmonella Enteritidis contamination.

AN - 68725309; 16245721 AB - Recovery of bacteria from shell eggs is important for evaluating the efficacy of processing and the quality and safety of the final product. Shell rinse (SR) techniques are easy to perform and widely used. An alternative sampling method involves crushing and rubbing the shell (CR). To determine the most appropriate method for recovering microorganisms from shell eggs, 358 shell eggs were collected from a commercial egg processor and sampled by SR and CR techniques. Total aerobic mesophiles and Enterobacteriaceae were enumerated on plate count and violet red bile glucose agar plates, respectively. Unwashed, in process, and postprocess eggs were evaluated in the study. Aerobic microorganism prevalence for eggshells sampled was similar for both methods (approximately 100%), but the log CFU per milliliter values were higher in the SR than the CR samples (3.2 and 2.2, respectively). Average Enterobacteriaceae recovery was similar for both methods (45 versus 40% for the SR and CR methods, respectively) when all eggs were considered together. This population was detected more often by SR when unwashed eggs were sampled (90 versus 56% for the SR and CR methods, respectively), equally by SR and CR for in-process eggs (30 versus 29.3% for the SR and CR methods, respectively), but more often by CR for postprocess eggs (10 versus 36% for the SR and CR methods, respectively). The SR technique was easier to perform and recovered larger numbers of aerobic organisms, particularly for unwashed eggs. However, the CR technique was more efficient for recovery of Enterobacteriaceae from postprocess eggs. Stage of shell egg processing may be an important consideration when choosing egg sampling methods.

AN - 68685684; 16220119 AB - To validate the use of para-aminohippuric acid (PAH) as a marker for measuring blood flow in wethers consuming a mixed diet of locoweed and blue grama hay. Fourteen sheep, stratified by bodyweight (BW), were assigned to one of three treatments: 0.8 mg swainsonine (SW)/kg BW (HI), 0.2 mg SW/kg BW (LO), and no SW (Control). Sheep were fed various ratios of locoweed and blue grama hay to deliver SW treatments, for 28 days prior to infusion of PAH. Concentrations of SW and activities of alkaline phosphatase (Alk-P) and aspartate aminotransferase (AST) in serum were measured to confirm exposure to SW and subclinical intoxication. A single 20-ml injection of 5% PAH was delivered into the jugular vein after subclinical intoxication had been achieved. Blood samples were collected and serum analysed for PAH immediately prior to injection, then every 5 min from 5-30 min, and every 10 min from 30-60 min, following injection of PAH. Effective delivery of SW was evident from the greater concentrations of SW measured in the serum of HI compared with LO animals (p<0.05). No significant differences were detected in the rate of elimination (range 0.097-0.108 L/min), elimination half-life (range 6.62-7.24 min), apparent volume of distribution for the central compartment (range 7.14-9.72 L), and clearance (range 0.73-0.92 L/min) of PAH, between treatments. Subclinical intoxication with SW did not affect the pharmacokinetics of PAH. Thus, use of downstream dilution of PAH is a valid method to determine the rate of blood flow in nutrient flux experiments that involve consumption of locoweed.

AN - 68680470; 16198380 AB - Landraces of maize (Zea mays ssp. mays) and its wild teosinte relatives (Zea mays spp. parviglumis and mexicana) were surveyed for sensitivity to fumonisin B(1), a phytotoxin produced by the maize pathogen Gibberella moniliformis. Only two of 42 Z. mays samples were highly insensitive to FB(1) (ED(50) = ca. 200 microM). The teosintes and 76% of the maize landraces were moderately or highly sensitive to FB(1) (ED(50) < or = 30 microM), which indicates that FB(1) sensitivity is likely to be an ancestral trait in Z. mays. F(1) generations derived from crosses between FB(1)-sensitive maize inbred B73 and insensitive landraces were significantly less sensitive than B73. Thus, our data indicate that FB(1)-insensitivity is a relatively rare but heritable trait in maize. We also report the sensitivity of maize to other Gibberella toxins - beauvericin, diacetoxyscirpenol, and moniliformin.

AN - 68650843; 16204551 AB - Multiple strains of Campylobacter coli, C. jejuni, C. helveticus, C. lari, C. sputorum, and C. upsaliensis isolated from animal, clinical, or food samples have been analyzed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Whole bacterial cells were harvested from colonies or confluent growth on agar and transferred directly into solvent and then to a spot of dried 3-methoxy-4-hydroxycinnamic acid (matrix). Multiple ions in the 5,000- to 15,000-Da mass range were evident in spectra for each strain; one or two ions in the 9,500- to 11,000-Da range were consistently high intensity. "Species-identifying" biomarker ions (SIBIs) were evident from analyses of multiple reference strains for each of the six species, including the genome strains C. jejuni NCTC 11168 and C. jejuni RM1221. Strains grown on nine different combinations of media and atmospheres yielded SIBI masses within +/-5 Da with external instrument calibration. The highest-intensity C. jejuni SIBIs were cytosolic proteins, including GroES, HU/HCj, and RplL. Multiple intraspecies SIBIs, corresponding probably to nonsynonymous nucleotide polymorphisms, also provided some intraspecies strain differentiation. MALDI-TOF MS analysis of 75 additional Campylobacter strains isolated from humans, poultry, swine, dogs, and cats revealed (i) associations of SIBI type with source, (ii) strains previously speciated incorrectly, and (iii) "strains" composed of more than one species. MALDI-TOF MS provides an accurate, sensitive, and rapid method for identification of multiple Campylobacter species relevant to public health and food safety.

Last updated - 2017-01-18 ER - TY - JOUR T1 - Salmonella enterica virulence genes are required for bacterial attachment to plant tissue. AN - 68647542; 16204476 AB - Numerous Salmonella enterica food-borne illness outbreaks have been associated with contaminated vegetables, in particular sprouted seeds, and the incidence of reported contamination has steadily risen. In order to understand the physiology of S. enterica serovar Newport on plants, a screen was developed to identify transposon mutants that were defective in attachment to alfalfa sprouts. Twenty independent mutants from a pool of 6,000 were selected for reduced adherence to alfalfa sprouts. Sixty-five percentage of these mutants had insertions in uncharacterized genes. Among the characterized genes were strains with insertions in the intergenic region between agfB, the surface-exposed aggregative fimbria (curli) nucleator, and agfD, a transcriptional regulator of the LuxR superfamily, and rpoS, the stationary-phase sigma factor. Both AgfD and RpoS have been reported to regulate curli and cellulose production and RpoS regulates other adhesins such as pili. The intergenic and rpoS mutants were reduced in initial attachment to alfalfa sprouts by 1 log unit compared to the wild type. Mutations of agfA, curli subunit, and agfB in S. enterica serovar Enteritidis differentially affected attachment to plant tissue. The agfA mutation was not reduced in ability to attach to or colonize alfalfa sprouts, whereas the agfB mutation was reduced. Thus, agfB alone can play a role in attachment of S. enterica to plant tissue. These results reveal that S. enterica genes important for virulence in animal systems are also required for colonization of plants, a secondary host that can serve as a vector of S. enterica from animal to animal.

AN - 68596914; 16099185 AB - Fusarium verticillioides (teleomorph Gibberella moniliformis) is a pathogen of maize worldwide and produces fumonisins, a family of mycotoxins that have been associated with several animal diseases as well as cancer in humans. In this study, we sought to identify fungal genes that affect fumonisin production and/or the plant-fungal interaction. We generated over 87,000 expressed sequence tags from nine different cDNA libraries that correspond to 11,119 unique sequences and are estimated to represent 80% of the genomic complement of genes. A comparative analysis of the libraries showed that all 15 genes in the fumonisin gene cluster were differentially expressed. In addition, nine candidate fumonisin regulatory genes and a number of genes that may play a role in plant-fungal interaction were identified. Analysis of over 700 FUM gene transcripts from five different libraries provided evidence for transcripts with unspliced introns and spliced introns with alternative 3' splice sites. The abundance of the alternative splice forms and the frequency with which they were found for genes involved in the biosynthesis of a single family of metabolites as well as their differential expression suggest they may have a biological function. Finally, analysis of an EST that aligns to genomic sequence between FUM12 and FUM13 provided evidence for a previously unidentified gene (FUM20) in the FUM gene cluster.

AN - 68585638; 16162534 AB - Salmonella is one of the most serious foodborne pathogenic bacteria in the United States, causing an estimated 1.3 million human illnesses each year. Dairy cows can be reservoirs of foodborne pathogenic bacteria, including Salmonella spp.; it is estimated that from 27 to 31% of dairy herds across the United States are colonized by Salmonella. The present study was designed to examine the occurrence of Salmonella spp. on dairies and to examine the serotypic diversity of Salmonella isolates on sampled dairies from across the United States. Fecal samples (n = 60 per dairy) were collected from 4 dairies in each of 4 states for a total of 960 fecal samples representing a total population of 13,200 dairy cattle. In the present study, 93 of 960 samples (9.96%) collected were culture-positive for Salmonella enterica. At least one Salmonella fecal-shedding cow was found in 9 of the 16 herds (56%) and the within-herd prevalence varied in our study from 0% in 7 herds to a maximum of 37% in 2 herds, with a mean prevalence among Salmonella-positive herds of 17%. Seventeen different serotypes were isolated, representing 7 different Salmonella serogroups. There were 2 or more different serogroups and serotypes present on 7 of the 9 Salmonella-positive farms. Serotypes Montevideo and Muenster were the most frequent and widespread. From our data, it appears that subclinical colonization with Salmonella enterica is relatively common on dairy farms and is represented by diverse serotypes on US dairy farms.

On day 4 of culture, medium was discarded, plates were rinsed twice with serum-free medium and cells were cultured in 1 ml fresh medium without serum and challenged individually with 10(-10), 10(-8) or 10(-6) M [Ala(15)]-h growth hormone-releasing factor-(1-29)NH(2) (GRF); 10(-9), 10(-8) or 10(-7) M GnRH or 10(-9), 10(-8), 10(-7) or 10(-6) M NPY individually or in combinations with 10(-9) or 10(-8) M GnRH or 10(-8) or 10(-6)M GRF. Cells were exposed to treatment for 4 h at which time medium was harvested and quantified for LH and GH. Basal LH secretion (control; n = 7 pituitaries) was 12 +/- 6 ng/well. Relative to control at 4 h, 10(-9), 10(-8) and 10(-7) M GnRH increased (P 0.4) basal LH secretion nor 10(-8) M GnRH-induced increase in LH secretion but 10(-9) M GnRH-stimulated LH secretion was reduced by NPY and was not different from control or GnRH alone. Basal GH secretion (control; n = 7 pituitaries) was 56 +/- 12 ng/well. Relative to control at 4 h, 10(-10), 10(-8) and 10(-6) M GRF increased GH secretion by 111%, 125% (P < 0.01) and 150% (P < 0.01), respectively. Only 10(-6) M (134%) and 10(-7) M (125%) NPY increased (P < 0.04) basal GH secretion. Addition of 10(-9), 10(-8) and 10(-7) M NPY in combination with 10(-8) M GRF suppressed (P < 0.04) GRF-stimulated GH secretion. However, 10(-9) M NPY enhanced (P < 0.06) the GH response to 10(-6) M GRF. These results demonstrate that NPY may directly modulate GH secretion at the level of the pituitary gland.

AN - 68017464; 16005765 AB - In a nitrogen (N) saturated forest downwind from Los Angeles, California, the cumulative response to long-term background-N and N-amendment on black oak (Quercus kelloggii) was described in a below-average and average precipitation year. Monthly measurements of leaf and branch growth, gas exchange, and canopy health attributes were conducted. The effects of both pollutant exposure and drought stress were complex due to whole tree and leaf level responses, and shade versus full sun leaf responses. N-amended trees had lower late summer carbon (C) gain and greater foliar chlorosis in the drought year. Leaf water use efficiency was lower in N-amended trees in midsummer of the average precipitation year, and there was evidence of poor stomatal control in full sun. In shade, N-amendment enhanced stomatal control. Small differences in instantaneous C uptake in full sun, lower foliar respiration, and greater C gain in low light contributed to the greater aboveground growth observed.

AN - 68016260; 16005766 AB - In the Retezat Mountains concentrations of O3, NO2 and SO2 in summer season 2000-2002 were low and below toxicity levels for forest trees. While NH3 concentrations were low in 2000, the 2001 and 2002 concentrations were elevated indicating possibility for increased N deposition to forest stands. More than 90% of the rain events were acidic with pH values 25% of foliage injured increased from 9.1% in 2000 to 16.1% in 2002. Drought that occurred in the southern Carpathians between fall 2000 and summer 2002 and frequent acidic rainfalls could cause the observed decline of forest condition. Both Norway spruce and European beech with higher defoliation had lower annual radial increments compared to the trees with low defoliation. Ambient O3 levels found in the Retezat did not affect crown condition of Norway spruce or European beech.

Given the possibility of a longer time difference for soil development before deposition of any tephra, we obtained analytical data and reexamined the study thinking that an age difference of 6000 yr would have implications for soil classification and possibly suggest new series. Holocene tephra in the very fine sand (vfs) fraction (0.05-0.10 mm) ranges from 1% in the ridges to 93% in the troughs. The mean of the vfs fraction tephra content of soils on ridges of the higher, and presumably older, terraces (11%) is significantly less than that of soils on ridges of the lower and younger terraces (45%). The mean tephra content in the troughs (77%) does not vary by terrace level. The maximum fine-earth (<2 mm) allophane content of the youngest ridge is 96.3 g kg (super -1) and that of the youngest trough is 95.4 g kg (super -1) . These amounts are greater than five times those of ridge soils on the older terraces. Only about 20 to 50% of the estimated Mount Mazama tephra fall remains on the older Bonner and Kootenai soils, whereas the older Rathdrum soil retains about 400% of the estimated Mount Mazama tephra fall. Minor amounts occur in the Histosol on the flood plain. Isotic 50- to 100-mu m thick coatings on some A and B horizon sands indicate that weathering has been minor. Low spodic-horizon indicators (Alo and Feo in subsurface horizons), and high ammonium oxalate extract optical densities of surface horizons, also suggest no fulvic acid leaching. Below the tephra influence, however, the outwash grains have anisotropic clay minerals showing that some weathering may have occurred before deposition of the tephra. The higher allophane content, higher NaF pH, and higher P-retention of lower terrace ridge soils, as compared with higher terrace ridge soils, results mostly from variation in the amount of their tephra and now justifies classifying ridge soils on higher and lower terraces into different taxa and opens the possibility of differentiating soil series by terrace level.

Optical ages of dune stabilization just below a strand line at approximately 240 m and fluvial deposits below 210 m document an initial draw-down of Lake Minong of at least 30 m prior to approximately 10,000 cal yr. BP. This event was perhaps the result of overwash and incision of Minong's outlet after influx of drainage from Lake Agassiz. Under our model, the optical ages of dunes and shorelines subsequently emplaced just below 225 m at approximately 9,500 cal yr BP require a transgression of Minong prior to another drop to a strand line at approximately 215 m. Since this scenario requires two sequences of early Holocene transgression and outlet incision for Lake Minong, it depends upon some revision of the outlet history for the Superior Basin, one of which has recently been proposed. A subsequent drop of Minong of unknown magnitude after approximately 8,500 cal yr B.P. is inferred from 14C dating of wood fragments from a vibracore from Muskallonge Lake below a prominent beach scarp. Optical ages of five dunes within the Tahquamenon River basin suggest that a Holocene lake ("Lake Bergquist") existed behind an elevated bay mouth barrier south of present Tahquamenon Falls. The lake was impounded and persisted for 500-1000 years after the initial withdrawal of a bay of Lake Minong from the area. The outlet of Lake Bergquist was breached after approximately 9,500 cal yr BP, possibly as a result of a sudden flood surge of water from Lake Agassiz into Lake Minong and thence into Lake Bergquist. Signatures of this event are interpreted from GPR profiles and DEMs. Stratification of soil mapping units (i.e., two-storied soils) in a GIS reveal a 10-15 km long silt plume trending SE away from abandoned Minong shorelines and a well-defined pattern of stratified silt over clay within the Tahquamenon River valley. Distributions of OSL ages obtained during this study suggest that the rapid drainage of large lakes explains most dune building episodes in interior eastern Upper Michigan.

Significant losses have occurred for those who unknowingly build on collapsible soils as well as significant cost increases have been incurred by those who are aware of the hazard and take remedial measures to develop the site. New Mexico is undergoing dramatic urban development and expansion of it cities and communities beyond the Rio Grande Valley terraces and flood plain onto the alluvial fans from the mountains. The alluvial fans upon which urban development is occurring also happen to be the environment of collapsible soils. The arid climate seldom wets the surface soils to a depth of a more than a few centimeters. Intense very brief thunderstorms occurring during the summer monsoon season are greatly intensified the uplift of mountain ranges. Resultant flash floods carry large sediment loads from the sparsely vegetated mountain foothills onto the alluvial fans. The highly porous structure of the mudflow or debris flow remains intact and is often further buried. Cementation by ubiquitous calcium carbonate and cohesion of clay and silt minerals to sand grains provides considerable strength to the soil when dry. During urban development, arroyos are intercepted by flood control structures or canals to protect homes. Roads and home sites are graded into the landscapes exposing cuts up to several meters in depth. Irrigation systems are installed to support landscaping. Wells and septic systems are utilized if the reach of municipal water and sewage services is exceeded. Water entering the soil through irrigation and waste disposal exceeds that than realized during the formation of the native landforms and soils several fold. Rainfall runoff which seldom occurred before development is concentrated by impermeable surfaces such as roofs, driveways, and streets and drains into landscaping, roadside ditches and low spots permeating several tens of meters in the coarse textured soils. The introduction of water reduces the soil strength and induces collapsible which is transferred to the soil surface with devastating effect upon structures. Up to one meter or more collapse has been observed. Creation of awareness and recognition of the expression of the hazard and remediation measures are important in preventing future losses.

Five different farm size measures are considered (acres operated per farm, real land and building value per farm, real cash receipts per farm, real cash receipts plus government payments per farm, and an imputed measure of the real capital service flow per farm) in order to make a more general statement about the impacts of government policies on farm size. It was found that the impacts of government policies on farm size are in general robust to the measure of farm size considered. More specifically, it was found that R&D, extension, and government payments all have positive effects on farm size. Reprinted by permission of Routledge, Taylor and Francis Ltd.

Significant changes in mechanical properties, especially maximum load and tensile strength, were obtained for fibrils derived from several cellulosic sources, including cotton, softwood, and bacterial cellulose. For extruded starch plastics, the addition of cotton-derived microfibrils at 10.3% (w/w) concentration increased Young's modulus by 5-fold relative to a control sample with no cellulose reinforcement. Preliminary data suggests that shear alignment significantly improves tensile strength. Addition of microfibrils does not always change mechanical properties in a predictable direction. Whereas tensile strength and modulus were shown to increase during addition of microfibrils to an extruded starch thermoplastic and a cast latex film, these parameters decreased when microfibrils were added to a starch-pectin blend, implying that complex interactions are involved in the application of these reinforcing agents.

Src-family tyrosine kinases (STKs) are known to be activated by LPS in monocytes/macrophages. Therefore, we determined the role of STKs in TLR4 signaling pathways and target gene expression in macrophages. The activation of NF[kappa]B, and p38 MAPK, and the expression of inducible nitric oxide synthase (iNOS) induced by LPS were not affected in macrophages deficient in three STKs (Lyn, Hck, and Fgr). These results suggest that the deletion of the three STKs among possibly nine STKs is not sufficient to abolish total activity of STKs possibly due to the functional redundancy of other STKs present in macrophages. However, two structurally unrelated pan-inhibitors of STKs, PP1 and SU6656, suppressed LPS-induced iNOS expression in MyD88-knockout as well as wild-type macrophages. The suppression of iNOS expression by the inhibitors was correlated with the downregulation of IFNb (a MyD88-independent gene) expression and subsequent decrease in STAT1 phosphorylation. Moreover, PP1 suppressed the expression of IFNb and iNOS induced by TRIF, a MyD88-independent adaptor of TLR4. PP1 suppressed STAT1 phosphorylation induced by LPS, but not by IFNb suggesting that STKs are involved in the primary downstream signaling pathways of TLR4, but not the secondary signaling pathways downstream of IFNb receptor. Together, these results demonstrate that STKs play a positive regulatory role in TLR4-mediated iNOS expression in a MyD88-independent (TRIF-dependent) manner. These results provide new insight in understanding the role of STKs in TLR4 signaling pathways and inflammatory target gene expression.

This information, together with the locations of active fires detected by the MODIS instrument, is essential for understanding the seasonal trends and interannual variability of fires and their impacts on air pollution, atmospheric chemistry, and global climate. We compared aerosol optical thickness derived from MODIS, five automated sun photometers of the Aerosol Robotic Network (AERONET), and 38 Forest Service (FS) handheld sun photometers in western Zambia from 20 August to 20 September 2000. Aerosol optical thicknesses derived from AERONET sun photometers and FS sun photometers were also compared in the same region between mid-June and late September 2000. Our objectives were to validate the AOT measurements by MODIS and to investigate the factors that affect AOT measurements. We demonstrated that in the regions of intense biomass burning. MODIS aerosol optical thickness was consistently 40-50% lower at 470, 550, and 660 nm compared with ground-based AOT measurements by automated and handheld sun photometers and airborne measurements by NASA Ames Airborne Tracking 14-channel Sunphotometers (AATS-14). The satellite look angles can influence the MODIS AOT values, with the actual MODIS AOT values being as much as 0.06 higher than model-calculated MODIS AOT values on the right edge of the MODIS scene. This phenomenon may be due to error in the assumed aerosol scattering phase function or surface directional properties. Density of vegetation cover can also affect MODIS measurements of aerosol optical thickness.

Uncertainties about the true extent of larval dispersal have impeded our understanding of the ecology and evolution of marine species as well as our attempts to effectively manage marine populations. Because direct measurements of larval movements are difficult, genetic markers have often been used for indirect measurements of gene flow among marine populations. Here we examine data from allozymes, mitochondrial DNA sequences, and microsatellite length polymorphisms to assess the extent of gene flow among populations of the burrowing crustacean Callichirus islagrande. All three types of markers revealed a genetic break between populations separated by the Louisiana Chenier Plain. The extent of mitochondrial sequence divergence across this break indicates that the nominal species, C. islagrande, consists of at least two lineages that have been reproductively isolated for about a million years. Within the eastern lineage microsatellite allele frequencies were significantly heterogeneous among populations as little as 10 km apart. Maximum likelihood estimates of gene flow and effective population size based on a coalescent model for the microsatellite data indicated that local populations are nearly closed. A model-based clustering method identified four or five groups from the microsatellite data, although individuals sampled from each location generally consisted of mixtures of these groups. This suggests a mechanism that would lead to genetic differentiation of open populations: gene flow from different source populations that are themselves genetically distinct.

Cercosporella acroptili (Bremer) U. Braun was identified as a possible biological control agent for A. repens, and a morphologically similar Cercosporella sp. recently was found damaging to C. solstitialis in the field. Because both fungi are potentially important for biological control of the respective weeds, studies were undertaken to ascertain whether the isolates were identical based on morphology, pathogenicity, growth and spore production, and genetics (molecular characterization of the internal transcribed spacer regions of the ribosomal RNA genes). Differences in these variables between the two isolates were sufficient to indicate that the isolate from C. solstitialis was distinct and justified a new description at the species level: Cercosporella centaureicola sp. nov.

The current single representative-particle-size approach in the erosion component of the U.S. Water Conservation Laboratory surface irrigation-simulation software, is being extended to track individual size fractions of the sediment mix. This requires the adaptation of existing empirical transport-capacity formulas to the small silt particle sizes in the mix. A modification of Laursen's 1958 formula based on recognition of a laminar sublayer in the turbulent flow near the furrow boundary is proposed to eliminate computed negative transport of very small particles. The assumption that the formula is sufficiently well grounded theoretically to warrant some application to sediment sizes smaller than those in its empirical database leads to plausible results. Ultimate justification will be based on comparisons of simulated sediment-load hydrographs with field measurements.

This goal was supplemented by research of groundwater origin, groundwater chemical composition and its changes. Field measurements, analyses of water samples and statistical evaluation of hydrometeorological data were used to gain and process the data. It was showed that overexploitation of groundwater in the catchment resulted in distinct diminishing of stream flow discharges in low flow periods, groundwater level dropping and disturbance of hydraulic connection between surface and groundwater. Groundwater quality was quite stable during the whole period of observation. Groundwater modeling was proposed to be used for the re-estimation of utilizable groundwater amounts in the catchment.

During the next 9 days, a total of 37 soil samples were obtained from these plots and other off-plot areas. Spectrophotometric analyses of dual aliquots of soil samples were performed to detect absorbance of capsaicin ( lambda max at 282nm). Analysis of variance showed that absorbance readings from points of capsicum application (augured holes) were 30-fold greater than for samples obtained 30-40cm distant (F=19.21, df 1/4.22, p<0.0105). Soybean-oil plot and off-plot soil samples yielded negligible absorbance readings. Thus, capsicum oleoresin persisted for 10 days in this type of soil, but migration was minimal.

We monitored dynamics of snag populations on 1-ha plots in southwestern mixed-conifer (n = 53 plots) and ponderosa pine (Pinus ponderosa, n = 60 plots) forests in north-central Arizona from 1997 to 2002. Of 2,240 snags marked in 1997, at least 76% remained standing in 2002, 17% had fallen and were relocated as logs, 0.5% were cut down, and the remainder (6% ) were unaccounted for. Snag density increased significantly in mixed-conifer forest but not in ponderosa pine forest. Snag density increased mainly in the smaller size classes in both forest types. Density of large snags (46 cm in diameter and 9 m in height) increased slightly but nonsignificantly from 1997 levels in both forest types, and fell below current targets for retention. Species composition of snags differed between 1997 and 2002 in ponderosa pine forest, but not in mixed-conifer forest, and decay-class distributions differed among years in both forest types. A classification-tree analysis indicated that a ratio of height to diameter, species, and diameter were key variables in predicting whether a snag survived from 1997 to 2002. These results provide empirical data on snag populations and dynamics in this area and establish a basis for longer-term monitoring of snag populations and dynamics. FOR. SCI. 51(5):396- 405.

We expand the scope of a prior 50-year demographic study of a 20.6-ha stand by (1) extending the census period, (2) comparing diameter distributions in the large stand with those of a smaller (2.3-ha) stand, and (3) examining small-diameter ingrowth of red oaks into both stands. Oaks displayed bell-shaped or even-aged diameter distributions in 1926, suggesting a history of disturbance from timber removal, grazing, and fire. These exogenous disturbances were suppressed starting in 1917 with acquisition of the property by Purdue University. Subsequent censuses indicated considerable ingrowth of nonoak stems into both stands. Oaks that were mid-sized in 1926 gradually moved through the size classes and were replaced by younger individuals in the small stand but not in the center of the large stand. The survey of red oak saplings confirmed this pattern, revealing numerous recruits in the small stand but virtually none in the large stand. These data support the view that oaks are failing to regenerate in part due to shade-intolerance and a waning disturbance regime in the large stand interior. FOR. SCI. 51(5):406- 416.

An Improved Resource for the Small-Grains Community AN - 20224628; 6505499 AB - GrainGenes (http://wheat.pw.usda.gov) is an international database for genetic and genomic information about Triticeae species (wheat [Triticum aestivum], barley [Hordeum vulgare], rye [Secale cereale], and their wild relatives) and oat (Avena sativa) and its wild relatives. A major strength of the GrainGenes project is the interaction of the curators with database users in the research community, placing GrainGenes as both a data repository and information hub. The primary intensively curated data classes are genetic and physical maps, probes used for mapping, classical genes, quantitative trait loci, and contact information for Triticeae and oat scientists. Curation of these classes involves important contributions from the GrainGenes community, both as primary data sources and reviewers of published data. Other partially automated data classes include literature references, sequences, and links to other databases. Beyond the GrainGenes database per se, the Web site incorporates other more specific databases, informational topics, and downloadable files. For example, unique BLAST datasets of sequences applicable to Triticeae research include mapped wheat expressed sequence tags, expressed sequence tag-derived simple sequence repeats, and repetitive sequences. In 2004, the GrainGenes project migrated from the AceDB database and separate Web site to an integrated relational database and Internet resource, a major step forward in database delivery. The process of this migration and its impacts on database curation and maintenance are described, and a perspective on how a genomic database can expedite research and crop improvement is provided.

This study was designed to examine the effect of a grassland wildfire on grasshopper community composition and population densities of three grasshopper subfamilies in western North Dakota northern mixed-grass prairie with sampling in paired burned and unburned plots. A rapidly moving fire occurred in late October 1999, after egg-overwintering grasshoppers had died. Vegetation biomass and nitrogen content of grasses did not differ statistically between burned and unburned plots in 2000. The fire negatively affected grasshopper population densities the year after the fire, but species diversity was not affected by the fire. Much of the reduction in grasshopper population densities was caused by a decline in densities of Gomphocerinae species. Grasshopper subfamily densities did not differ statistically between burned and unburned plots in 2001. Additional research is needed to determine the mechanisms leading to the reduction in Gomphocerinae species densities.

Among the individual traits, innate-immune responses have the potential to reduce both individual mortality and the spread of pathogens among colony members. An understanding of the costs and benefits of such responses can provide a more complete understanding of a primary risk of social life, horizontal disease transmission among colony members. Here we assess the impacts of individual immunity on colony-level disease in honey bee (Apis mellifera) colonies following exposure to an important bacterial pathogen (Paenibacillus larvae subsp. larvae, cause of the disease American foulbrood). Colony-level disease rates were negatively correlated with the immune responsiveness of colony members, as assessed by larval transcript levels for the gene encoding the antibacterial peptide abaecin. Concomitantly, colonies whose members mounted a stronger abaecin response showed significantly lower productivity, indicating a colony-level cost to this immune response. The results show considerable variation across colonies in an immune trait important for survival, and point toward a significant trade-off between this trait and colony productivity.

In a previous study, 138 of 141 (97.8%) bottlenose dolphins (Tursiops truncatus) from the coasts of Florida and California had antibodies to T. gondii by the modified agglutination test (MAT). Although the MAT has been found to be highly sensitive and specific for T. gondii antibodies from several species of terrestrial animals, it has not yet been validated for T. gondii infections in marine mammals. Furthermore, T. gondii has yet not been isolated from dolphins. In the present study, sera from 146 (60 from the 2004 samples and 86 from the 2003 samples) T. truncatus from the coastal areas of South Carolina and Florida were tested for antibodies to T. gondii. Sera from 2004 were tested by the MAT, the indirect fluorescent antibody test (IFAT), the Sabin-Feldman dye test (DT), an indirect hemagglutination test (IHAT), an enzyme-linked immunosorbent assay (ELISA), and Western blot. All 60 dolphins were seropositive, with MAT titers of 1:20 in 3, 1:40 in 19, 1:80 in 29, 1:160 in 2, 1:1,280 in 3, 1:2,560 in 2, and 1:5,120 or higher in 2, and these results were confirmed in another laboratory. The DT titers of these dolphins were <1:10 in 53, 1:800 in 3, 1:1,600 in 2, and 1:3,200 in 2. The IHAT titers were <1:64 in 52, 1:128 in 1, 1:512 in 2, and 1:2,048 in 5. The IFAT titers were <1:20 in 3, 1:20 in 11, 1:40 in 36, 1:80 in 2, 1:160 in 1, and 1:320 or higher in 7. All 7 DT-positive dolphins had high MAT titers, but 2 were negative by the IHAT. Western blot results closely followed MAT results; ELISA results matched MAT results, which were 1:40 or higher. In sera from the 2003 samples, MAT antibodies were found in 86 of 86 dolphins with titers of 1:25 in 29, 1:50 in 23, 1:100 in 27, 1:200 in 3, 1:1,600 in 1, and 1:3,200 in 3; these sera were not tested by other means. Overall, MAT antibodies were found in all 146 dolphin sera tested. Because marine mammals are considered sentinel animals indicative of contamination of the coastal and marine waters by T. gondii oocysts, serologically positive infections need to be validated by the detection of T. gondii organisms in the tissues of seropositive animals.

Pre-harvest A. parasiticus infection and aflatoxin contamination are usually severe in peanuts that are grown under drought stressed conditions; however, drought tolerant peanut lines have less aflatoxin contamination. The objective of this study was to identify resistance genes in response to Aspergillus parasiticus infection under drought stress using microarray and real-time PCR. To identify transcripts involved in the resistance, we studied the gene expression profiles in peanut genotype A13 which is drought tolerant and resistant to pre-harvest aflatoxin contamination, using cDNA microarray containing 384 unigenes selected from two expressed sequenced tag (EST) cDNA libraries challenged by biotic and abiotic stresses. A total of 42 up-regulated genes (log sub(2) ratio > 1) in several functional categories were detected under both A. parasiticus challenge and drought stress. A total of 52 up-regulated genes were detected in response to drought stress alone. There were 25 genes commonly expressed in both treatments. The top 20 up-regulated gene from A. parasiticus challenge and drought stress were selected for validation of their expression levels using real-time PCR. A13 was also used to study the functional analysis of these genes and a possible link of these genes to the resistance trait. Although the selected genes identified by microarray analysis were validated by real-time PCR, further investigations are needed to characterize each of these genes. Gene probes could then be developed for application in breeding selection.

In this study, lactic acid bacteria (LAB), which are known to produce antimicrobial compounds important in the biopreservation of food, were evaluated to determine if the same antimicrobial properties can be used to inhibit mould fungi that typically colonize wood. Based on biomass measurement, cell-free supernatants from Lactobacillus casei subsp. rhamnosus and Lactobacillus acidophilus grown in deMan Rogosa Sharpe (MRS) broth inhibited 95-100% growth of three mould fungi and one stain fungus associated with wood-based building materials. Lactic acid and four unknown compounds [el] kDa molecular weight were fractionated from the culture supernatant by thin layer chromatography and high-performance liquid chromatography. Antifungal activity, which was attributed to one or more unknown metabolites, was retained during heating and neutralization. A 1:2 dilution of L. casei supernatant inhibited 100% growth of all test fungi.

This technology utilized an infrared sensor to monitor the surface temperature of beef frankfurters during microwave heating. The aim was to increase the surface temperature of frankfurters to a set point lethal to L. monocytogenes. A feedback control mechanism was used to control the power to the microwave oven. Results indicated that the simple on-off control mechanism was able to maintain the surface temperature of beef frankfurters near the respective set points of 75, 80 or 85C used in this study. This pasteurization process was able to achieve a 7-log reduction of L. monocytogenes in inoculated beef frankfurters using a 600-W nominally rated microwave oven within 12-15 min. If optimized, this system may provide the food industry with a terminal, postlethality pasteurization technology to kill L. monocytogenes in ready-to-eat meats within the final packages.

Early detection of this pathogen is necessary for disease control and reduction of economic loss. In this communication, the loop-mediated isothermal amplification method (LAMP) that amplifies DNA with high specificity and rapidity at an isothermal condition was evaluated for rapid detection of E. ictaluri. A set of four primers, two outer and two inner, was designed specifically to recognize the eip18 gene of this pathogen. The LAMP reaction mix was optimized. Reaction temperature and time of the LAMP assay for the eip18 gene were also optimized at 65 super(o)C for 60 min, respectively. Our results show that the ladder-like pattern of bands sizes from 234 bp specifically to the E. ictaluri gene was amplified. The detection limit of this LAMP assay was about 20 colony forming units. In addition, this optimized LAMP assay was used to detect the E. ictaluri eip18 gene in brains of experimentally challenged channel catfish. Thus, we concluded that the LAMP assay can potentially be used for rapid diagnosis in hatcheries and ponds.

The abundance and composition of carabids collected from pitfall traps placed in hybrid dent corn were used to determine which species are consistently present and abundant in Iowa carabid communities and to test for population differences in these species caused by transgenic (Bacillus thuringiensis [Bt]) or insecticide-based pest management. Power analyses were also used to evaluate the adequacy of the experimental design. Carabid collections indicate Harpalus pensylvanicus DeGeer is the best choice to sample based on its apparent ubiquity and abundance in Iowa and other corn-producing states. However, population levels were time-dependent, and composition of carabid communities differed between locations. Considering the numerical dominance of a few species per field, the two to four most abundant species might be used to effectively represent local carabid communities. H. pensylvanicus populations were impacted by insecticide use, but no effects of Bt were found. Power analyses indicated that with the experimental design and replication employed, only large effects were detectable; based on the variation between plots, increased replication is needed to make detection of either moderate (30-50%) or small (<30%) effects likely. The recent release of transgenic corn with coleopteran toxicity highlights the importance of these results when evaluating potential unintended effects of these crops on ground beetles.

Bacillus subtilis Tu-100 significantly reduced (P less than or equal to 0.05) the incidence of disease caused by S. sclerotiorum on oilseed rape at harvest in two trials conducted in fields artificially infested with this pathogen. Mean plant dry weight was significantly greater (P less than or equal to 0.05) and mean plant length was significantly greater (P less than or equal to 0.07) at the seven-true-leaf stage with the Tu-100 treatment than with the control. Mean seed yield per 120 plants at harvest was significantly greater (P less than or equal to 0.05) in the second field trial with treatments containing isolate Tu-100. B. subtilis Tu-100 also promoted the growth of hydroponically grown oilseed rape. Plants were approximately 15% greater in dry weight (P less than or equal to 0.0001) and 6% greater in length (P less than or equal to 0.0025) when grown in the presence of isolate Tu-100 in Hoagland's solution, compared with the noninoculated control. In gnotobiotic studies, the lacZ-tagged strain B. subtilis Tu-100(pUC18) was detected within all roots of oilseed rape. Isolate Tu-100 did not persist in the ectorhizosphere of oilseed rape. Populations of this isolate decreased from 8.5 x 10 super(8) colony-forming units (CFU) per seed to approximately 10 super(2) CFU in the plant ectorhizosphere within 30 days of sowing in autoclaved soil.

Fungi were picked from the cadavers, transferred to media, and ultimately isolated to purity. The individual fungal cultures were then used to infect Formosan subterranean termite workers. A single fungal isolate, C4-B, taxonomically identified as Metarhizium anisopliae (Metschnikoff), was found to cause rapid mortality of Formosan subterranean termite alates. This is the first report of a biological control agent for termite alates. In initial experiments, C4-B was more lethal to both alates and workers compared with M. anisopliae strain ESC 1, previously marketed as the termite biocontrol agent BioBlast. Dose-response assays in which Formosan subterranean termite alates were exposed to a known concentration of C4-B spores revealed that 10 super(6) spores/ mu l killed 100% of the alates in 3 d, both 10 super(5) and 10 super(4) spores/ mu l in 6 d, 10 super(3) spores/ mu l in 9 d, and 10 super(0) spores/ mu l in 12 d. Assays with workers demonstrated that 10 super(6) and 10 super(5) spores/ mu l killed 100% of the workers in 6 d. In an experiment to test the transfer of inoculum from infected workers to uninfected nestmates, 62.8% of the workers died in 21 d when only 20% of the workers had been inoculated. Mortality of alates caused by C4-B was tested at two field sites by dispersing fungal spores on grassy lawns and collecting alates from the treated areas. Alates thus infected showed 100% mortality by day 5, whereas only 64.8% of untreated control alates from the same collection area were dead on that day.

Whole cantaloupes inoculated with E. coli O157:H7 and L. monocytogenes at 5.27 and 4.07 log sub(10) CFU/cm super(2), respectively, and whole honeydew melons inoculated with E. coli O157:H7 and L. monocytogenes at 3.45 and 3.05 log sub(10) CFU/cm super(2), respectively, were stored at 5 degree C for 7 days. Antimicrobial washing treatments were applied to inoculated whole melons on days 0 or 7 of storage and surviving bacterial populations and the numbers transferred to fresh-cut pieces were determined. At days 0 and 7 treatment with HPLNC significantly (p - 0.05) reduced the numbers of both pathogens, by 3 to 4 log CFU/cm super(2) on both types of whole melon. Treatment with HPLNC was significantly (p - 0.05) more effective than treatment with 2.5% hydrogen peroxide. While fresh-cut pieces prepared from stored whole melons were negative for the pathogens by both direct plating and by enrichment, fresh-cut pieces from cantaloupe melons treated with 2.5% hydrogen peroxide were positive for both pathogens and pieces from honeydew melons were positive for E. coli 0157:H7. The native microflora on fresh-cut melons were also substantially reduced by HPLNC treatment of whole melons. The results suggest that HPLNC could be used to decontaminate whole melon surfaces and so improve the microbial safety and quality of fresh-cut melons.

The endosperm-specific beta -amylase (Bmy1), the more abundant isozyme in cereal seeds, has been thoroughly characterized. The lesser abundant beta -amylase2 (Bmy2) has not been biochemically characterized from any cereal seeds. Characterization of Bmy2 from two commonly grown barley cultivars, Morex and Steptoe, was a major objective of this study. The bmy2 cDNAs were sequenced, expressed in Escherichia coli, and the recombinant enzymes (rBmy2) characterized. The relative hydrolysis rates of various alpha -D-glucans and the pH activity optima of Morex and Steptoe rBmy2s were the same and not significantly different from barley rBmy1. The Morex rBmy2 was 7 degree C more thermostable than the Steptoe rBmy2, determined by differences in their T sub(50) values, and is more thermostable than any reported wild-type beta -amylasel. Three amino acid differences were identified between the two Bmy2 sequences and the contributions to enzyme thermostability evaluated by site-directed mutagenesis. Examination of mutant enzymes with one amino acid substitution revealed that each of the three residues contributed approximately 3 degree C to the thermostability of the Morex wild-type rBmy2. Mutant enzymes with two amino acid substitutions contributed approximately 5.6 degree C, and the triple amino acid mutant enzyme contributed approximately 8.7 degree C to thermostability. To date, no quantitative trait loci (QTL) for malting quality traits have been associated with the bmy2 locus. Should an association be discovered, the Morex bmy2 allele, containing D238, M337, and Q362, provides a discrete signature of a thermostable beta -amylase2 that could be targeted for marker assisted selection.

Mammary gland infections cost the US dairy industry approximately $2 billion dollars annually and have a similar impact in Europe. In the absence of effective treatments or breeding strategies to enhance mastitis resistance, we have created transgenic dairy cows that express lysostaphin in their mammary epithelium and secrete the antimicrobial peptide into milk. Staphylococcus aureus, a major mastitis pathogen, is exquisitely sensitive to lysostaphin. The transgenic cattle resist S. aureus mammary gland challenges, and their milk kills the bacteria, in a dose dependent manner. This first step in protecting cattle against mastitis will be followed by introduction of other genes to deal with potential resistance issues and other mastitis causing organisms. Care will be taken to avoid altering milk's nutritional and manufacturing properties.

The goal of this study was to quantify the population dynamics of the invasive, subtropical shrub, Ardisia elliptica (Myrsinaceae), growing in a disturbed area of Everglades National Park, Florida, USA. We used bootstrap sampling and randomization tests to test hypotheses about spatial and temporal variation in population dynamics. Five populations spanning a range of habitats were studied for three years. Significant spatial and temporal variation in fruit production, relative growth, fates of vegetative individuals, and population growth rates were detected; however, spatial variation among populations had an overall stronger effect than temporal variation. Population growth rates were greater than 1 or not different from 1, implying that populations are on average increasing in size. Similar to most other shrubs, prospective analysis showed that stasis of large stage classes had the highest elasticities. However, a retrospective analysis indicated that it was variation in growth to larger stage classes that contributed the most to observed variation in population growth rates. Simulations suggest that historically higher population growth rates of A. elliptica were necessary to produce current population sizes in Everglades National Park.

Phosphorus excretion has not been reported in red imported fire ants, Solenopsis invicta Buren. Quantification of phosphoric acid in worker fecal droplets and larval anal liquid of S. invicta was performed. Phosphoric acid was trimethylsilylated using N,O-bis(trimethylsilyl)trifluoroacetamide, and the tris(trimethylsilyl) phosphate was analyzed using gas chromatography-mass spectrometry. Phosphoric acid made up 2.13 plus or minus 1.08% (SD) of the dry weight of worker fecal droplets and 2.09 plus or minus 0.72% of the larval anal liquid. The rate of phosphoric acid production in workers was 0.08 plus or minus 0.024 mu g/ant/d. Because the hindgut of red imported fire ant larva is separated from the midgut, the excretory products in larval anal liquid are primarily of metabolic origin. The presence of phosphoric acid in larval anal liquid shows that red imported fire ants excrete phosphoric acid.

All orchards were treated with 500-1,000 Isomate-C PLUS dispensers/ha during 2000-2002. Traps baited with pear ester caught their first moth significantly later on average than the paired codlemone-baited traps, but timing of peak moth catch during each moth flight coincided with both types of lures. The timing of first male moth capture in pear ester-baited traps was significantly earlier than the first female moth; and the percentage of male moths in the total numbers of moths captured ranged from 55 to 60% over the three seasons. The percentage of female moths caught by pear ester-baited traps that were mated exceeded 80% each year. Pear ester-baited traps caught similar numbers of moths as codlemone-baited traps during 2000. However, the density of sex pheromone dispensers per hectare was increased in most orchards in 2001-2002; and pear ester outperformed codlemone-baited traps in both years.

A number of field experiments have shown that top-down control by avian predators can limit grasshopper populations, but the effects of avian predators on grasshopper populations can differ between years and between sites in the same habitat. I conducted experiments examining grasshopper populations in avian exclosures and control plots for 3 yr at two locations in eastern Montana. Avian predation had variable direct and indirect effects on grasshopper communities at the two locations. Grasshopper population densities, species richness, and diversity at the two sites were not consistently significantly affected by avian predation, indicative of weaker top-down effects. The effects of predation varied among years and between the two sites. Avian predators modified body size composition of grasshopper populations through size-selective predation on medium-bodied grasshoppers. Even in years when avian predators did not limit grasshopper populations, selective predation seemed to indirectly mediate competitive interactions among grasshoppers. Birds reduced the proportion of presumably competitively superior medium-bodied grasshoppers, and small-bodied grasshoppers increased in abundance.

(Lepidoptera: Pyralidae) at constant temperatures of 18, 22, 26, and 30 degree C. Development rates were fitted to the equation Y = a + b ln x. The theoretical development threshold was calculated as T0 = exp (-a/b), resulting in T0 = 12.48 and 12.78 degree C for females and males, respectively. Degree-days for development ranged from 233.92 in males at 18 degree C to 338.73 in females at 30 degree C. In all temperature treatments, P. maculiventris immatures consumed a mean of approximately eight prey items. Mean immature body weights were higher at higher temperatures, but females were heavier than males only at the fifth instar. In adult female P. maculiventris, age at first oviposition ranged from 2.7 d at 30 degree C to 13.4 d at 18 degree C. Percentage of egg hatch was lowest at 18 degree C (11%) and highest at 30 degree C (36.4%). Survivorship curves showed a linear decline with time, the steepest curves at the highest temperatures. Total number of eggs laid per female ranged from 429.4 at 18 degree C to 755.4 at 26 degree C. Mean egg numbers were fitted to a surface equation as eggs = (-6.658 + 0.432T) d exp(-0.002Td) where d and T are age (days) and temperature ( degree C), respectively. Net and gross reproductive rates were highest at 26 degree C (R0 = 379.126; gross reproductive rate [GRR] = 491.273 [female]/[female]) and lowest at 18 degree C (R0 = 207.873; GRR = 294.972). Generation and doubling times were shortest at 30 degree C (T = 35.021 and DT = 4.270 d). Intrinsic and finite rates of increase were also highest at 30 degree C (r = 0.1623; lambda = 1.1763). Reproductive parameters were recalculated using numbers of eggs that actually hatched, resulting in lower values, although the effects of temperature did not change. In the context of mass rearing P. maculiventris, 26 degree C is the optimal temperature tested, but female predators >21 d should be not be used because they may not be capable of laying viable eggs.

We examined the time of moth capture in the diel cycle and the recapture rates of marked moths in sex pheromone mating disruption (MD) and untreated orchards. The attractiveness of pear ester-baited traps was compared among five apple cultivars. Experiments also assessed the influence of trap height, the distance of the trap from sex pheromone dispensers, proximity of foliage surrounding the trap, trap size, and proximity of adjacent clean and codling moth-injured fruit on moth captures. The responses of male and female moths significantly differed in response to many of these factors. For example, the time of peak female capture occurred earlier than for males. A higher proportion of recaptured, marked moths were females in MD versus untreated orchard plots. Significantly more male but not female moths were caught in traps placed high versus low in the tree canopy. Traps placed on the perimeter of the canopy caught significantly more female moths than traps placed within the canopy and surrounded by foliage. Smaller trap surfaces caught significantly more males than females. Traps placed adjacent to uninjured fruit caught significantly more females than traps placed away from fruit. No differences occurred between sexes in response to other factors: significantly higher counts of both sexes occurred in blocks of 'Granny Smith' versus four other apple cultivars; recapture rates of marked moths were not different at release points ranging from 10 to 50 m for either sex; and trap placement relative to MD dispensers or injured versus uninjured fruits was not a significant factor affecting moth catches or their sex ratio. Effective monitoring for either or both sexes of codling moth should consider standardizing these factors. Lure and kill strategies should include factors that optimize the captures of female moths.

This synthesis reviews related research over the more than two decades since area projection modeling systems replaced expert opinion approaches in the national Resources Planning Act (RPA) assessments, as part of state of the art approaches for regional and national resources assessments. Such models reflect that key land base changes such as afforestation and deforestation are driven by quite different socio-economic factors. Projections of area changes are important for a wide range of natural resource analyses, including those for wildlife habitat, timber supply, global climate change, water, recreation, and others. The demand for applications in global change analyses has increased recently, and the synthesis addresses information needs in such macro assessments. Significant challenges in the research area in general include systematic integration of approaches and therefore findings across resource areas to support sustainability analyses. Another challenge is a unified view of future forest conditions constructed at a scale that serves all of these uses adequately. JF - General technical report.

But little capacity currently exists for utilizing such material and capacity of sufficient scale to have a significant impact on the economics of small diameter removals will only be added if predictable feedstocks can be assured. The FIA BioSum modeling framework that incorporates Forest Inventory and Analysis (FIA) plot data, a transportation cost model, a treatment cost accounting module, a log valuation model, and a crown fire hazard evaluator was applied to a 28 million acre study area containing 6200 FIA plots spanning the Eastern Cascades, Southern Cascades, Klamath Mountains and Modoc Plateau ecosections of western Oregon and northern California. Up to nine fuel treatment prescriptions with a high likelihood of producing a substantial reduction in crown fire hazard were simulated for each plot, and 221 potential biomass processing sites were considered. With four 50 MW biomass-fueled power plants strategically distributed over the study area, up to 5.3 million acres could be effectively treated with net revenue of 2.6 billion dollars, a merchantable yield of 9.5 billion cubic feet, and a biomass yield of 79 million green tons, if net-revenue maximizing fuel treatments are selected. If merchantable volume minimizing treatments are selected instead for these 5.3 million acres, net revenue would be negative 2.6 billion dollars, merchantable yield would be 3.6 billion cubic feet and biomass yield would be 75 million green tons. With the constraint that every acre generate positive net revenue, only 2.6 million acres would be treated, even if the net revenue maximizing treatment is selected. JF - General technical report.

Most fire planning models rely on subjective estimates of travel times between pre-determined points on the landscape. This paper describes a raster-based travel time model that provides greater accuracy, objectivity, and flexibility in estimating travel times between points on the landscape. The methodology used to create the travel time prediction model integrates existing GIS data with empirical travel data collected using GPS. Although the need to develop this rose from development of WIRAS (Wildland Initial Response Assessment System), it will be useful to many wildland fire pre-suppression planning efforts where there is a relationship between the time it takes fire suppression resources to respond and the final size and resultant costs of suppression.

Traditionally, this information has been presented in tabular format. A spatial format will provide a more useful mechanism for summarizing and utilizing this important information and can provide new insight into the causes, or at least correlates, with differences in sizes of forest landholdings. The objective of this study was to investigate techniques for modeling forest parcel size in order to facilitate future efforts to generate a national map depicting the distribution of forest parcel sizes. County tax records and land-cover data for Madison County, New York, were used to generate a dataset containing forest parcel size by owner. This area was selected because, unlike most of the country, the land ownership parcel data are readily available in a format conducive to spatial analysis. Ancillary data included both social and biophysical predictor variables. Multiple linear regression, neural network, and decision trees were used to model these data. The models were tested using validation datasets and accuracy was assessed with enhanced kappa statistics. A decision tree was selected as the final method because it provided superior validation results, fewer parameters to adjust, and ease of explanation and visualization to non-experts.

Objectives of the analysis were to verify short-term thinning estimates; to gain an understanding of long-term implications and capabilities of commercial thinning on the forest; to develop a model to be used for analyzing vegetation management proposals and policies in the future; and to provide useful information about thinning that could be linked with short, mid and long-term management strategies. A linear programming model was constructed, and scenarios with varying mixes of operational and allocation constraints were examined. Where practical, multiple entry prescriptions offered the best prospect of achieving a sustained flow of forest products. Limiting thinning to Late Seral Reserve (LSR) lands or stands previously managed greatly reduces available harvest volumes in the short term. Issues that need further investigation are fuels treatments and management objectives on lands outside of LSRs. JF - General technical report.

This paper describes features of WIRAS, a discrete-event stochastic simulation model that can assist fire planners in wildfire preparedness planning and policy analysis. WIRAS simulates, according to user-defined rules, all phases of initial attack resource management and movement to meet the service needs in response to the ebb and flow of fire workload over the landscape and through time. In an operational setting WIRAS is used to test alternative preparedness programs against annual historical fire occurrence datasets to gauge performance with respect to spatially and temporally variable fire seasons. Planning capability at the national and regional scales is complemented by a unique ability of WIRAS to evaluate local preparedness programs within a larger geographic context to account for the impact of external competition for shared suppression resources, like airtankers, helitack, and smokejumpers.

Beef steaks (N = 48) were inoculated with a five-strain cocktail of Escherichia coli O157:H7 and treated with blade tenderization (BT), HDP or a combination of BT followed by HDP (BTH). Control and treated steaks were cooked to 54.4C (undercooked), 62.8C (medium rare) and 71.1C (medium) on open-hearth Farberware grills. HDP treatment reduced E. coli O157:H7 populations by 0.3 log sub(10) cfu-g, which was not different (P > 0.05) from untreated controls. At each endpoint cooking temperature, E. coli O157:H7 survival was always higher in BT-treated steaks than in untreated steaks cooked to corresponding temperatures. This could be due to migration of surface bacteria to the interior of the muscle thereby protecting bacteria from the lethality of heat. E. coli O157:H7 populations in BTH-treated steaks cooked to 71.1C were nondetectable and were significantly different from BT-treated steaks cooked to 71.1C. Results suggest that BT of intact beef muscle does transfer surface bacteria to the interior of the muscle, which would necessitate a combination of elevated cooking temperatures (>71.1C) and a treatment like HDP for inactivation of bacteria.

Samples from 854 farms in 21 states were collected and enriched in tetrathionate broth to amplify any salmonellae present, and DNA was isolated from the resulting biomass. One hundred one samples (11.8%) were shown to contain Salmonella enterica using the real-time PCR assay, whereas conventional culture techniques detected the pathogen in only 22 (2.6%) of the samples. A conventional PCR assay targeting a different gene from Salmonella enterica confirmed the presence of the organism in 94 of the real-time PCR-positive samples. Thus, assay of milk samples by real-time PCR indicates that the prevalence of Salmonella enterica in US bulk tank milk is substantially higher than previously reported.

Samples were assayed for pathogens by observing sporulation on plated leaf tissue. Among 3,600 leaves assayed, eight species of the three genera were observed. Features and criteria for the practical identification of species on plated leaf samples are described. Sporulation by dematiaceous hyphomycetes was observed on 97% of leaves; a single pathogen was observed on 20% and two to five pathogens were observed on 77% of leaves. Distributions of leaves among classes with one to five pathogens per leaf, for sites within years, always differed significantly (P = 0.01) from a Poisson distribution and usually included fewer leaves than expected with four or five pathogens. Significant (P = 0.05) variation in frequencies of occurrence of pathogens among 72 samples of 50 leaves each was attributed to pathogen species, sampling times, and species time interactions. Exserohilum rostratum, Curvularia lunata, and Bipolaris cynodontis were the most frequent pathogens across years and sites; B. spicifera and C. geniculata were intermediate; and B. hawaiiensis, B. sorokiniana, and B. stenospila were least frequent. For the five most common pathogens, significant differences in frequency among locations were commonplace. Six pathogens exhibited significant (P = 0.05) positive and negative correlations with others in overall frequencies of occurrence across years, sampling times, and sites. However, chi super(2) tests of dual occurrence indicated that interactions between specific pairs of pathogens in or on leaves are not likely to be major causes for overall frequency correlations. Results indicate that dematiaceous hyphomycetes typically infect forage bermudagrass on swine waste application sites in complexes rather than as individual species; that E. rostratum, C. lunata, and B. cynodontis are the predominant pathogens; and that frequencies of pathogens often differ significantly between locations.

Riparian hosts that do not maintain sufficient X. fastidiosa populations for acquisition may not be significant inoculum reservoirs. We examined X. fastidiosa populations in systemically infected riparian hosts (California blackberry, California grapevine, elderberry, Himalayan blackberry, periwinkle) at two coastal locations (Mendocino and Napa) with two methods of quantitation (culturing and real-time polymerase chain reaction) from 2003 to 2004. In summer and autumn, X. fastidiosa populations were above the threshold for BGSS acquisition in periwinkle, Himalayan blackberry, and California grapevine at both locations. The only X. fastidiosa-positive plants detected in spring at both locations were periwinkle and Himalayan blackberry, suggesting that these species may contribute to long-term survival of X. fastidiosa. California blackberry and elderberry may not be important reservoirs of X. fastidiosa, given that very few plants of either species maintained infections. Higher X. fastidiosa populations in California grapevine, Himalayan blackberry, and periwinkle in Napa, relative to plants in Mendocino, may partially explain the higher PD incidence in Napa vineyards.

Symptoms resembled those of the genus Crinivirus (family Closteroviridae), and large populations of whiteflies were observed in the fields and on symptomatic plants. Although the identity of the whiteflies on the curcurbits was not determined, the greenhouse whitefly, Trialeurodes vaporariorum (Westwood) is known to be present in the region from where the samples were obtained. To identify the causal agent of the disease, leaf samples of symptomatic plants were collected from several farms. The leaf samples were dried with silica gel. Total RNA was extracted from leaf tissue of eight representative samples (two from healthy plants and six from symptomatic plants) using TRI Reagent (Molecular Research Inc., Cincinnati, OH). Reverse transcription-polymerase chain reactions (RT-PCR) containing one primer set at a time were performed using the Titan One-Tube RT-PCR kit (Roche Diagnostics Corp., Chicago IL) and primers specific for genes of cucurbit-infecting criniviruses, including the coat protein gene of Cucurbit yellow stunting disorder virus and the minor coat protein gene (CPm) of Beet pseudo-yellows virus (BPYV). Primers specific for the heat shock protein (HSP) gene (CYHSPF 5' GAGCGCCGCACAAGTCATC 3' and CYHSPR 5' TACCGCCACCAAAGTCATACATTA 3') of Cucumber yellows virus (CYV, a strain of BPYV) were designed based on published sequence data. In addition, primers specific for Cucurbit aphid-borne yellows virus and melon yellowing-associated flexivirus (MYVF 5' GGCTGGCAACATGGAAACTGA 3' and MYVR 5' CTGAAAAGGCGATGAACTA TTGTG 3') were used in RT-PCR reactions. Amplified DNA fragments of 333 and 452 bp were obtained in each of two samples obtained from symptomatic plants and only in separate reactions containing BPYV and CYV primer sets, respectively. Nucleotide sequence analysis of all purified PCR products verified their identity as variants of BPYV, with 97 and 99% sequence identity with reported CPm and HSP sequences, respectively. The two samples from Cucurbita moschata Duch. (ayote or squash) and Cucurbita pepo L. (escalopini or sunburst squash) were taken from a region around Paraiso, Cartago, Costa Rica. To our knowledge, this is the first report of BPYV in Costa Rica. The economic impact on cucurbit production has not yet been determined. Studies are underway to determine the prevalence and genetic variability of BPYV isolates in Costa Rica.

In order to effectively utilize stem rust resistance in the improvement of small grain cereals, it is necessary to monitor the virulence composition and dynamics in the stem rust population. Races of P. graminis from barberry, wheat, barley, and oat were surveyed across the United States during 2003. Aecial infections on barberry were primarily due to P. graminis f. sp. secalis, as inoculations using aeciospores failed to produce infection on wheat and oat. Race QFCS of P. graminis f. sp. tritici was the most common race identified from wheat and barley. Race QFCS has virulence on stem rust resistance genes Sr5, 8a, 9a, 9d, 9g, 10, 17, and 21 that are used for race identification. Race TTTT was identified in 2003. This race possesses virulence to all 16 stem rust resistance genes present in the wheat stem rust differentials and should be targeted in breeding for stem rust resistance. Race QFCN appeared to be a new race in the U.S. stem rust population. Races QCCJ and MCCF were identified, but at low frequencies. Seven races of P. graminis f. sp. avenae were identified from oat, and races NA-27, NA-29, and NA-67 were the predominant races. Race NA-76 was identified for the first time in the United States.

Colopterus truncatus and Carpophilus sayi are thought to be the principal sap beetle vectors in Minnesota. Field studies using wind-oriented funnel traps baited with aggregation pheromones of the insects were conducted during 2 years in east central Minnesota. The studies compared temporal flight dynamics of Colopterus truncatus and Carpophilus sayi from April through October, measured the proportion of dispersing adults of each species carrying viable pathogen propagules, and estimated the populations of contaminated dispersing beetles in oak (Quercus spp.) stands with and without oak wilt. Abundance of Colopterus truncatus peaked in either April or May, but the pathogen was most frequently isolated (20 to 45%) from beetles obtained from oak wilt sites from July through September. However, the highest contaminated insect population (CIP) generally occurred during April and May. Abundance of Carpophilus sayi peaked in October of both years, but the pathogen was most commonly isolated from beetles collected during May and June. The CIP was highest in June. The infective insect potential, as indexed by CIP, was greatest for both species in the spring and was greater for Colopterus truncatus than for Carpophilus sayi.

The genetic structure of field populations of P. tritici-repentis was determined using amplified fragment length polymorphism markers along with sequence data from the internal transcribed spacer region of the ribosomal DNA. Ninety-seven fungal isolates were collected from naturally infected wheat and wild grass species. The collection of 97 P. tritici-repentis isolates included races 1, 2, 3, 4, 5, ND7, and ND8 and was collected from North America, South America, and Europe. Results show no genetic grouping of fungal races nor do results indicate grouping based on geographic location indicating that the population is preferentially outcrossing in nature and that the introduction and spread of this population is either relatively recent or that there has been a constant worldwide flow of this fungus possibly by seed movement between continents.

Until now, the VKD carboxylase was known to be present only in the animal kingdom (i.e. metazoans that include mammals, fish, snails, and insects), and this restricted distribution and high sequence similarity between metazoan and Leptospira orthologs strongly suggests that Leptospira acquired the VKD carboxylase by horizontal gene transfer. In metazoans, the VKD carboxylase is bifunctional, acting as an epoxidase that oxygenates vitamin K to a strong base and a carboxylase that uses the base to carboxylate Glu residues in VKD proteins, rendering them active in hemostasis and other physiologies. In contrast, the Leptospira ortholog showed epoxidase but not detectable carboxylase activity and divergence in a region of identity in all known metazoan VKD carboxylases that is important to Glu interaction. Furthermore, although the mammalian carboxylase is regulated so that vitamin K epoxidation does not occur unless Glu substrate is present, the Leptospira VKD epoxidase showed unfettered epoxidation in the absence of Glu substrate. Finally, human VKD protein orthologs were not detected in the L. interrogans genome. The combined data, then, suggest that Leptospira exapted the metazoan VKD carboxylase for some use other than VKD protein carboxylation, such as using the strong vitamin K base to drive a new reaction or to promote oxidative damage or depleting vitamin K to indirectly inhibit host VKD protein carboxylation.

A numerical model was used to calculate available ground water in the Zohor depression--an aquifer transcending national boundaries between the Slovak Republic and Austria. The aquifer, formed by Quaternary sediments overlying Neogene sequences, is composed of various clays interbedded with layers of sand, gravel, sandstones, and conglomerates. The AQUA computer model package was used to simulate flow in the aquifer. For model compilation, the following data were used: (1) effective precipitation; (2) surface water levels in surface water gauging profiles; and (3) withdrawal amounts. Hydraulic parameters of the aquifer were estimated based on information from 86 wells located in the area. The model was verified using data on ground water levels from a monitoring network. The simulation of the aquifer system permitted the estimation of the available ground water in the study area, showing that an additional 587 L/s can be abstracted. Ground water inflows to the Morava River, which flows through the region, range from 745 to 3100 L/s.

In field tests on apple (Malus sp. 'Delicious'), we compared different application strategies for CpGV (Cyd-X, Certis USA, Clovis, CA) used in full-season programs against high pest populations. In replicated single tree plots, three rates (0.073, 0.219, and 0.438 liter ha super(-1)) and application intervals (7, 10, and 14 d) killed 81-99% of larvae in fruit and reduced the number of mature larvae recovered in tree bands by 54-98%. Although the proportion of deep entries declined by 77-98%, the amount of fruit injury was not reduced compared with controls. There was a statistical trend between increasing dosage and spray frequency intervals and virus effectiveness, but no interaction between these factors. In a commercial orchard, we assessed a standard (0.219 liter ha super(-1)) and two reduced rates of the virus (0.146 and 0.073 liter ha super(-1)) applied in a weekly spray program in replicated 0.2-ha blocks. In the first generation, fruit injury was reduced in virus-treated compared with three untreated blocks although the decrease was only significant at the standard rate. Mortality rates of larvae (in fruit) were greater than or equal to 90%, dose dependent, and comparable with rates observed from individual trees sprayed with equivalent treatments in the previous study. Rates of larval mortality declined at all dosages (81-85%) in the first part of the second generation. Most damage and proportionally less mortality occurred in the upper canopy. High pest pressures and untreated blocks contributed to significant damage and the study was terminated early. These data suggest virus programs can be tailored according to the localized pest pressure, but it may not prevent economic damage in high-pressure situations.

Analyses of the effects of land management on natural resources often rely on qualitative assessments that focus on single species to reflect the risk of wildlife extinction across a planning area. We propose a conceptual framework for sustainable management of wildlife habitat that explicitly acknowledges the greater risk of an extinction event when considering the viability of multiple species, e.g. an indigenous vertebrate fauna. This concept is based on the principle that the likelihood of at least one event (i.e. species extinction) is the joint probability of the extinction probabilities of individual species, assuming independence among species' responses to disturbance. We present an ecological rationale to support the view that, at a spatial scale of 10 super(4)-10 super(6) ha (i.e. planning area) and a temporal scale of 10 super(2) years (i.e. planning horizon), wildlife species operating at varying ecological scales respond relatively independently to disturbances typically associated with land management. We use a hypothetical scenario of a wildlife viability assessment and Monte Carlo simulation to demonstrate that the probability of 'any extinction' is consistently higher than the probability of the 'single most likely' extinction, and that the difference between these values increases as more disturbance-sensitive species (i.e. species at risk) are analyzed. We conclude that risk assessments that rely upon the most sensitive single species may substantially underestimate the risk of wildlife extinction across a planning area. Furthermore, the selection of a planning alternative based on relative threat of local extinction of wildlife populations can vary depending on which paradigm is used to estimate risk to viability across the planning area.

Although effective in reducing clinical disease and fecal shedding, these vaccines have severe disadvantages as well, including seroconversion of vaccinated animals and granulomatous lesions at the site of vaccination. DNA vaccines can offer an alternative approach that may be safer and elicit more protective responses. In an effort to identify protective M. avium subsp. paratuberculosis sequences, a genomic DNA expression library was generated and subdivided into pools of clones ( similar to 1,500 clones/pool). The clone pools were evaluated to determine DNA vaccine efficacy by immunizing mice via gene gun delivery and challenging them with live, virulent M. avium subsp. paratuberculosis. Four clone pools resulted in a significant reduction in the amount of M. avium subsp. paratuberculosis recovered from mouse tissues compared to mice immunized with other clone pools and nonvaccinated, infected control mice. One of the protective clone pools was further partitioned into 10 clone arrays of 108 clones each, and four clone arrays provided significant protection from both spleen and mesenteric lymph node colonization by M. avium subsp. paratuberculosis. The nucleotide sequence of each clone present in the protective pools was determined, and coding region functions were predicted by computer analysis. Comparison of the protective clone array sequences implicated 26 antigens that may be responsible for protection in mice. This study is the first study to demonstrate protection against M. avium subsp. paratuberculosis infection with expression library immunization.

When such species alter ecosystem processes, they have the potential to change the environmental context in which other species survive and reproduce and may also facilitate the invasion of additional species. We describe impacts of an invasive N sub(2)-fixing tree, Falcataria moluccana, on some of the last intact remnants of native wet lowland forest undergoing primary succession on 48-, 213-, and 300-yr-old lava flows of Kilauea Volcano on the island of Hawai'i. We measured litterfall, soil nitrogen (N) and phosphorus (P) availability, light availability, species composition, and forest structure in native-dominated stands and in stands invaded by Falcataria. Litter inputs increased 1.3-8.6 times, N mass of litterfall increased 4-55 times, and P mass of litterfall increased 2-28 times in invaded stands relative to native stands. C:N and C:P ratios of litterfall were lower, and N:P ratios higher, in invaded stands relative to native stands. Resin-captured soil N and P values were 17-121 and 2-24 times greater, respectively, in invaded stands relative to native stands on each of the three lava flows. Native species accounted for nearly 100% of total basal area and stem density in native stands, while alien species accounted for 68-99% of total basal area, and 82-91% of total stem density, in invaded stands. Compositional changes following Falcataria invasion were due both to increases in alien species, particularly Psidium cattleianum, and decreases in native species, particularly Metrosideros polymorpha. Results provide a clear example of how invasive tree species, by modifying the function and structure of the ecosystems that they invade, can facilitate invasion by additional nonnative species and eliminate dominant native species. Given the rarity and limited extent of remaining native-dominated wet lowland forests in Hawaii, and the degree to which Falcataria invasion alters them, we expect that the continued existence of these unique ecosystems will be determined, in large part, by the spread of this invasive species.

They are stable through many generations and can provide direct assessment of individual animal's genetic merit if they are in linkage disequilibrium and phase with functional genetic variation. Bovine chromosome 5 has been shown to harbor genetic variation affecting production traits in multiple cattle populations; thus, this chromosome was targeted for SNP-based marker development and subsequent association analysis with carcass and growth phenotypes. Discovery of SNP was performed in a panel of 16 sires representing two sires from each of seven beef breeds and two Holstein sires by PCR amplification and sequencing using primers designed from genomic sequence obtained by low-coverage sequencing of bacterial artificial chromosome (BAC) clones. From 550 SNP, 296 (54%) were tentatively identified as having a minor allele frequency >10%. Forty-five SNP derived from 15 BAC were chosen based on minor allele frequency and were genotyped in 564 steers and their sires. Production and carcass data were collected on the steers as a part of the Germplasm Evaluation (GPE), Cycle VII Project at the U.S. Meat Animal Research Center (Clay Center, NE), which involves of the evaluation of sires from seven of the most popular U.S. breeds. Haplotypes based on seven SNP derived from a BAC containing the bovine genes HEM1 and PDE1B were associated with traits related to carcass fat. Steers homozygous for the major haplotype had 0.15 plus or minus 0.04 cm less subcutaneous fat, 0.57 plus or minus 0.18 kg less rib fat, 0.18 plus or minus 0.07 lower yield grade, 1.11 plus or minus 0.35% less predicted fat yield, and 0.79 plus or minus 0.3% greater predicted retail product yield than heterozygotes. The frequency of the major haplotype was 0.70 in the steers, and it ranged from 0.44 (Limousin) to 0.98 (Simmental and Gelbvieh) in a panel consisting of an average of 20 purebred sires from each of the seven breeds. A second set of haplotypes based on four SNP derived from a BAC containing the genes NOL1 and CHD4 was associated with Warner-Bratzler shear force. Steers homozygous for the major haplotype had 0.27 plus or minus 0.11 kg greater shear force than those heterozygous for the major haplotype and one of two minor haplotypes. The frequency of the major haplotype was 0.59 in the steers and ranged from 0.27 (Hereford) to approximately 0.95 (Angus and Red Angus) in the panel of purebred sires. These results demonstrate the feasibility of targeting QTL regions for SNP-based marker development and that a low level of coverage can identify markers associated with phenotypic traits.

The use of group-specific primers in community DNA profiling applications can provide enhanced sensitivity and phylogenetic detail compared to domain-specific primers. Other uses for group-specific primers include quantitative PCR and library screening. The purpose of the present study was to develop several primer sets targeting commonly occurring and important groups. Primers specific for the 16S ribosomal sequences of Alphaproteobacteria, Betaproteobacteria, Bacilli, Actinobacteria, and Planctomycetes and for parts of both the 18S ribosomal sequence and the internal transcribed spacer region of Basidiomycota were examined. Primers were tested by comparison to sequences in the ARB 2003 database, and chosen primers were further tested by cloning and sequencing from soil community DNA. Eighty-five to 100% of the sequences obtained from clone libraries were found to be placed with the groups intended as targets, demonstrating the specificity of the primers under field conditions. It will be important to reevaluate primers over time because of the continual growth of sequence databases and revision of microbial taxonomy.

Few comparable pediatric data exist. OBJECTIVES: The objective of this study was to evaluate the relationships among vitamin D status, PTH, and calcium absorption in midpubertal boys and girls. METHODS: Calcium absorption was measured as part of an evaluation of the effects of prebiotics (inulin-type fructans) using a stable isotope method in 93 young adolescents, 12.7 plus or minus 1.0 yr of age, receiving diets averaging approximately 900 mg/d calcium. RESULTS: A significant positive relation to calcium absorption was found for serum 1,25-dihydroxyvitamin D (P = 0.048) and PTH (P = 0.007), but not for 25-OHD (P = 0.77). PTH was significantly inversely related to 25-OHD and was positively related to serum 1,25-dihydroxyvitamin D and osteocalcin. PTH was marginally significantly inversely related to lumbar spinal, but not whole body, bone mineral density. CONCLUSIONS: These data suggest that in adolescents, especially in the presence of vitamin D insufficiency, PTH secretion increases to adapt to higher rates of bone formation associated with growth. This results in higher serum 1,25(OH) sub(2)D concentrations and increased calcium absorption results. Vitamin D status, as reflected by the serum 25-OHD level, is not closely related to calcium absorption. Whether adaptation to low serum 25-OHD is adequate under physiologically stressful situations, including those leading to very low serum 25-OHD levels, is unknown.

The combination of scanning electronic microscopy and small deformation dynamic mechanical studies revealed that pectins with higher net electrical charges are more bioadhesive than the less charged ones. Both the negatively charged pectin formulation, P-25, and the positively charged formulation, P-N, were able to synergize with the mucus to produce rheologically strengthened gels. The highly esterified pectin, P-94, also synergized with the mucosal glycoproteins to form a gel structure via coil entanglements. The ex vivo studies further confirmed the microstructures of mucus gel networks with adsorbed pectins. When incubated with porcine intestinal mucus membrane, P-94 gels were found generally bound to the lumen area, P-25 gels were able to penetrate deeply near the wall area, P-N gels interacted with mucins via electrostatic bonding and dispersed into the whole area from the lumen to the wall. Hence, both P-N and P-94, by enhancing the protective barrier properties of mucus systems, may be useful alternatives for the treatment of mucus related irritation and infection. In drug-delivery systems, P-N and P-25 would deliver incorporated drugs mainly by pectin dissolution, while a diffusion mechanism would release drugs from P-94 gels.

These tractive elements also vary in the way that they impact the soil with some causing more soil disturbance than others. This soil disturbance includes soil compaction and rut formation which negatively impacts rainfall infiltration, rooting, and crop production while potentially increasing soil erosion and runoff. This paper will review a portion of the agricultural research that has been conducted related to soil impacts caused by the use of vehicle traffic in agricultural fields. Recommendations will also be made for ways to minimize the effects of vehicle traffic on soils when trafficking is necessary. These include: reducing axle load; reducing tractive element-soil contact stress by using radial tires, duals, and tracks; increasing soil drying prior to traffic; using conservation tillage systems which minimize vehicle traffic; using controlled traffic systems which eliminate random vehicle traffic across fields; and subsoiling to eliminate compacted soil profiles in crop growth zones. Soil compaction resulting from vehicle traffic may not be able to be completely eliminated, but it can be controlled and reduced through intelligent management of vehicle traffic.

The hydrolysis of soluble starch by concentrated crude preparations was found to be a nonlinear function of time at 30 and 40 degree C. Concentrates of supernatant fractions incubated without substrate exhibited poor stability at 30, 40, or 50 degree C, with 87% inactivation after 21 h at 30 degree C, 45% inactivation after 40 min at 40 degree C and 90% inactivation after 10 min at 50 degree C. Proteases known to be present in crude preparations had a temperature optimum of 50 degree C, but accounted for a small fraction of thermal instability. Inactivation at 30, 40, or 50 degree C was not slowed by adding 20 mg/ml bovine serum albumin or protease inhibitor cocktail to the preparations or the assays to protect against proteases. Purified amylase preparations were almost as thermally sensitive in the absence of substrate as crude preparations. The temperature optimum of the amylase in short incubations with Sigma Infinity Amylase Reagent was about 50 degree C, and the amylase required Ca super(+2) for activity. The optimal pH for activity was 5.0-9.0 on soluble starch (30 degree C), and the amylase exhibited a K sub(m) with 4-nitrophenyl- alpha -D-maltoheptaoside-4,6-O-ethylidene of 120 mu M at 22 degree C. The amylase in crude concentrates initially hydrolyzed raw starch at 30 degree C at about the same rate as an equal number of units of barley alpha -amylase, but lost most of its activity after only a few hours.

However, detailed velocity data needed to compute these metrics are difficult to obtain. Acoustic Doppler current profilers (ADCP) may be used to rapidly collect detailed representations of river velocity fields. Herein we demonstrate use of ADCP to obtain ecologically relevant data and compute associated metrics. Data were collected from four reaches of the Little Tallahatchie River in northern Mississippi. Sampled reaches were selected to observe velocity regimes associated with three distinctly different conditions: downstream from a major flow obstruction (a low weir), downstream from the apices of each of two bends, and within an extremely long, straight reach created by channelization. Three-dimensional velocity data sets from each site were used to compute metrics of habitat quality proposed by others. A habitat metric based on the presence of rotational flow in the vertical plane proved to be the best discriminator among conditions within the sampled reaches. Two of four habitat quality metrics computed from these measured velocities were greatest for the sharpest meander bend. ADCP hold great potential for study of riverine physical aquatic habitats, particularly at the reach scale. Additional work is needed to develop generally applicable field protocols and data reduction tools. Specifically, guidelines for ADCP settings and configuration appropriate for a range of riverine site conditions must be developed. Advances in instrumentation are needed to allow collection of information in closer proximity to the free surface and solid boundaries.

Generalized crop coefficient curves presented in the literature are limited to providing estimates of ET sub(c) for 'optimum' crop condition within a field, which often need to be modified for local conditions and cultural practices, as well as adjusted for the variations from normal crop and weather conditions that might occur during a given growing season. Consequently, the uncertainties associated with generalized crop coefficients can result in ET sub(c) estimates that are significantly different from actual ET sub(c), which could ultimately contribute to poor irrigation water management. Some important crop properties such as percent cover and leaf area index have been modeled with various vegetation indices (VIs), providing a means to quantify real-time crop variations from remotely-sensed VI observations. Limited research has also shown that VIs can be used to estimate the basal crop coefficient (K sub(cb)) for several crops, including corn and cotton. The objective of this research was to develop a model for estimating K sub(cb) values from observations of the normalized difference vegetation index (NDVI) for spring wheat. The K sub(cb) data were derived from back-calculations of the FAO-56 dual crop coefficient procedures using field data obtained during two wheat experiments conducted during 1993-1994 and 1995-1996 in Maricopa, Arizona. The performance of the K sub(cb) model for estimating ET sub(c) was evaluated using data from a third wheat experiment in 1996-1997, also in Maricopa, Arizona. The K sub(cb) was modeled as a function of a normalized quantity for NDVI, using a third-order polynomial regression relationship (r super(2)=0.90, n=232). The estimated seasonal ET sub(c) for the 1996-1997 season agreed to within -33 mm (-5%) to 18 mm (3%) of measured ET sub(c). However, the mean absolute percent difference between the estimated and measured daily ET sub(c) varied from 9% to 10%, which was similar to the 10% variation for K sub(cb) that was unexplained by NDVI. The preliminary evaluation suggests that remotely-sensed NDVI observations could provide real-time K sub(cb) estimates for determining the actual wheat ET sub(c) during the growing season.

The major sex pheromone component, Z,Z-3,13-ODDA, was attractive as a single component. A blend of Z,Z-3,13-ODDA with 1-3% of E,Z-2,13-ODDA (binary blend) was more attractive than the single component. A third component, Z,E-3,13-ODDA, was sometimes observed in GC-EAD analyses, and enhanced attraction to the binary blend in some field bioassays. Lures containing 1 mg of binary and ternary blends attracted 18 and 28 times more male DWB moths, respectively, than caged virgin females in field trials. Attraction was strongly antagonized by addition of as little as 0.5% of E,Z-3,13-octadecadienyl acetate (E,Z-3,13-ODDA). In a period of 12 wk in 2004, more than 60,000 males were captured in sticky traps baited with synthetic pheromone blends in six apple orchards in Virginia, West Virginia, and North Carolina. Lure longevity trials showed that similar to 76% of the pheromone remained in rubber septum lures after 12 wk in the field.

One such compound is geldanamycin (GA), a benzoquinone ansamycin originally isolated from Streptomyces hygroscopicus. We examined the effect of geldanamycin on egg hatch and juvenile motility in Caenorhabditis elegans and in two populations of the plant-parasitic nematode Heterodera glycines. When C. elegans eggs were exposed to geldanamycin, both hatch and motility were reduced by GA doses between 2 and 50 mu g/ml. The H. glycines inbred populations TN17 and TN18 exhibited low dose stimulation of hatch and motility, whereas levels occurring at higher GA doses were at or below control levels. These experiments represent the first demonstration of geldanamycin effects in C. elegans and H. glycines and suggest that the heat shock chaperone Hsp90, the known molecular target of geldanamycin, may be involved in nematode egg hatch and motility. This study also indicates that geldanamycin-producing strains of Streptomyces may be useful as biocontrol agents for nematodes.

Therefore, dam embankment erosion processes and the rate of breaching from overtopping events are important to both engineers and planners alike, who must predict impacts on local communities and surrounding areas affected by flooding. There is a distinct difference between the erosion processes of non-cohesive and cohesive embankments during overtopping. The USDA-ARS has conducted seven large-scale overtopping failure tests on cohesive embankments ranging in height from 1.5 to 2.3 m. The purpose of this study is to: (1) establish a better understanding of the erosion process of overtopped cohesive embankments, and (2) provide detailed data for future numerical model development, validation, calibration, and testing. Three soils were tested, two non-plastic SM silty sand materials and a CL lean clay. A four-stage breach erosion process was observed for cohesive embankments. The primary erosion processes observed and reported in this article for cohesive embankments during stages 2 and 3 were headcut migration and erosion widening. The rate of these two processes was observed to vary by several orders of magnitude and was observed to be strongly dependent on the soil material properties.

However, quantitative information on sampling error is rarely available for use in selecting appropriate sampling techniques and for evaluating the effects of various techniques on measured results. In an effort to quantify uncertainty in constituent flux measurement for flow-interval sampling techniques, water quality data were collected from two small watersheds in central Texas. Each watershed was instrumented with two automated samplers. One sampler was programmed to take high-frequency composite samples to determine the actual load for each runoff event. The other sampler collected discrete samples, from which 15 strategies with 1.32 to 5.28 mm volumetric depth sampling intervals with discrete and composite sampling were produced. Absolute errors were consistently larger for suspended sediment than for NO sub(3)-N and PO sub(4)-P for both individual event and cumulative loads, which is attributed to differences in the variability of within-event constituent concentrations. The mean event-specific coefficient of variation (CV) ranged from 0.53 to 0.69 for sediment, from 0.38 to 0.39 for NO sub(3)-N, and from 0.18 to 0.21 for PO sub(4)-P. Event-specific CV values were correlated with the magnitude of absolute errors for individual event loads, with mean r values of 0.52 and 0.57 for the two sites. Cumulative errors were less than plus or minus 10% for all sampling strategies evaluated. Significant differences in load estimate error resulted from changes in sampling interval, but increasing the number of composited samples had no effect; therefore, composite sampling is recommended if necessary to manage the number of samples collected.

This overshoot cannot be described by the conventional Richards equation. Here, solutions to the infiltrations using a popular nonequilibrium extension to the Richards equation are obtained using the traveling wave nature of the saturation profile. Quantitative comparisons are made to recent measurements of saturation overshoot. The nonequilibrium solutions can be made to fit the flux range of the overshoot, but the fit to the tip saturations is fair to poor at best. Also, small changes in porous media size and roughness require large changes in the magnitude of the nonequilibrium term to match the flux range. The results suggest that the nonequilibrium capillary pressure does not include the correct physics that controls the overshoot.

However, the recommendation did not include guidance on how to analyze such responses. In this article, we describe the results of a carefully designed split sample experiment that allowed for comparison of a standard dichotomous- choice referendum treatment to a treatment that included the option of responding unsure to the contingent valuation question in addition to the standard vote in favor and vote against response categories. We are able to examine several options for dealing with the unsure responses and conclude that the unsure responses should be included in the value estimation as the respondents who choose this response category are distinct from respondents who choose the vote in favor and vote against response categories.

Vineyard in Oregon, USA AN - 1034818924; 17024460 AB - The spatial and temporal development of grapevine roots and associated mycorrhizal fungi was studied in 1999 and 2000 in a 21-year-old, Pinot Noir (Vitis vinifera L.) vineyard located on a Jory soil (Palehumult, silty clay loam) in Oregon, USA. The density of woody roots and fine (primary) roots deemed to be physiologically active (based on color and cellular integrity) were determined at monthly intervals in the weed-free, vine row and in the alleyway between rows at two depths (0-50 and 50-100 cm). The majority of fine roots were growing in the vine row at 0-50 cm depth. Fine root density did not change dramatically over the 1999 or 2000 seasons until the time of fruit harvest in the fall. Apparently, new root growth kept pace with turnover (death) prior to harvest, but new root growth surpassed turnover in the fall after fruit harvest. Colonization of fine roots by arbuscular mycorrhizal fungi (AMF) was consistently high in the vine row at 0-50 cm depth, but was lower in roots growing in the alleyway, and in roots below 50 cm. The proportion of fine roots containing arbuscules (the site of nutrient exchange in arbuscular mycorrhizas) was also greatest for roots growing in the vine row at 0-50 cm depth. Arbuscular colonization of these roots increased prior to budbreak in the spring, reached a high level (50-60% root length) by early summer, and remained high until after the time of leaf senescence in late fall. Arbuscular colonization decreased rapidly by December of 1999 when November rainfall exceeded 200 mm, but did not decline by December of 2000 when November rainfall was below 80 mm. The availability of important plant nutrients in the soil, with the exception of Mg and Zn, was higher in the upper 50 cm of the soil profile where the majority of roots were found. In addition, available nitrate and phosphate were higher in the vine row than in the alleyway soil. Seasonal changes in leaf nutrient concentrations of Pinot Noir confirmed findings in other cultivars, but fluctuations of N, P, and K concentrations in fine roots over the season suggested that fine roots may play a role in nutrient storage, as well as nutrient uptake, in grapevines. Grapevines grown in Oregon direct significant resources to roots and AMF after fruit harvest and substantial post-harvest nutrient uptake may extend into the early winter.

Flux measurements were begun in the spring of 2003, using vented (N sub(2)O) and dynamic (NO) chambers, one to three times per week, year round, within plots that were cropped continuously to corn (Zea mays L.) under conventional-till (CT) and no-till (NT). Plots were fertilized at planting in late April with rates of 0, 134 and 224 kg N ha super(-1) and corn was harvested in late October or early November each year. N sub(2)O and NO fluxes increased linearly with N application rate in both years. Compared with CT, NT did not significantly affect the emission of N sub(2)O but resulted in much lower emission of NO. In 2003 and 2004 corn growing seasons, the increase in N sub(2)O-N emitted per kg ha super(-1) of fertilizer N added was 14.5 and 4.1 g ha super(-1) for CT, and 11.2 and 5.5 g ha super(-1) for NT, respectively. However, the increase in NO-N emitted per kg ha super(-1) of fertilizer N added was only 3.6 and 7.4 g ha super(-1) for CT and 1.6 and 2.0 g ha super(-1 )for NT in 2003 and 2004, respectively. In the fallow season (November 2003 to April 2004), much greater N sub(2)O (2.0-3.1 times) and NO (13.1-16.8 times) were emitted from CT than from NT although previous N application did not show obvious carry-over effect on both gas emissions. Results from this study reveal that NT has potential to reduce NO emission without an obvious change in N sub(2)O emission under continuous irrigated corn cropping compared to CT.

We were interested to know whether transferrin genes in the red imported fire ant, Solenopsis invicta, are similarly induced by microbial challenge. Hence, the cDNA and structure of a gene exhibiting significant homology to insect transferrins were elucidated for S. invicta. The cDNA was comprised of 2417 nucleotides, excluding the poly(A) tail, with a large open reading frame of 2106 nucleotides. The predicted translation product of the S. invicta tranferrin (SiTf) gene was a 702 amino acid polypeptide with an estimated molecular mass of 77.3 kDa and a pI value of 5.66, characteristics consistent with transferrin proteins. Comparative analysis of genomic and cDNA sequences revealed that the SiTf gene was comprised of 8 exons. Quantitative real-time PCR was used to examine the expression of SiTf. Expression of SiTf was induced in worker ants exposed to Beauveria bassiana conidia. Autoclave-killed conidia did not elicit a SiTf induction response from worker ants. Genes, like SiTf, responding to microbe attack or infection may provide a unique approach to assist in the discovery of microbial control organisms for the target insect pest.

Past studies suggested that the life form change from erect forest to krummholz had advantages to forest function. Aboveground net primary productivity (NPP) and organic matter production per unit leaf area and growing season day were higher in krummholz than in adjacent short erect forests at lower elevation. We compared tall erect, short erect, and krummholz lenga stands in terms of the concentration, accumulation, fluxes, turnover, and use-efficiency of nutrients (N, P, K, Ca, and Mg) along an elevation gradient (220-640m) in Tierra del Fuego (Valle de Andorra, 54 super(o)9'S, 68 super(o)2'W). With few exceptions, patterns of decreasing values of nutrient concentration, nutrient stock, nutrient flux, and nutrient turnover reversed at the krummholz, which had higher values of these parameters than an adjacent short erect forest at lower elevation. Nutrient cycles accelerated at the krummholz but nutrient use-efficiency of organic matter production and nutrient return to the forest floor decreased. Several functional attributes of krummholz support the notion that this life form has functional advantages at timberline. For example: (1) a shift towards fast turnover compartments for nutrient storage; (2) a switch from high storage of nutrients in stemwood biomass to nutrient storage in branch biomass; (3) faster rates of internal nutrient transfer (recycling and retention); (4) greater dependence on biotic recycling of nutrients; (5) morphological characteristics associated with leaf size, leaf duration, number of leaves, and leaf area to sapwood area ratio. Nutrient cycling attributes measured in Tierra del Fuego span values reported for forests across temperate and boreal latitudes, with krummholz and tall erect forests representing either the low or the high values. Lenga krummholz is different from coniferous krummholz in North America's tundra in that lenga appears to be a nutrient-rich forest that acts as a nutrient sink, while coniferous krummholz scavenge for nutrients on tundra soils and reduce their nutrient pools.

6412760 AB - Almost half of all clinical cases of mastitis are caused by Gram-negative bacteria. Among these bacteria, intramammary infection by Pseudomonas aeruginosa remains one of the most refractory to antibiotic therapy. The ability to recognize potentially harmful pathogens whether previously encountered or not, as well as the induction of an initial pro-inflammatory response to these pathogens, are critical components of host innate immunity. Although the innate immune response to another Gram-negative mastitis-causing pathogen, Escherichia coli, has been well-characterized, little is known about the response to other Gram-negative bacteria, including P. aeruginosa. The objective of the current study was to characterize the systemic and localized bovine innate immune response to intramammary infection with P. aeruginosa. The contralateral quarters of ten mid-lactating Holstein cows were challenged with either saline or P. aeruginosa. Following the establishment of infection, milk samples were collected and assayed for changes in cytokine and growth factor concentrations, complement activation, and changes in the levels of soluble CD14 (sCD14) and lipopolysaccharide (LPS)-binding protein (LBP), two accessory molecules involved in host recognition of Gram-negative bacteria. Initial increases in milk somatic cell counts were evident within 12h of experimental challenge and remained elevated for >=3 weeks. Increased permeability of the mammary gland vasculature, as evidenced by elevated milk levels of BSA, was initially observed 20h post-infection and persisted for 2 weeks. Within 32h of challenge, increased levels of IL-8, TNF- alpha , IL-10, and IL-12 were detected, however, the elevated levels of these cytokines were not sustained for longer than a 24h period. In contrast, elevations in IL-1 beta , IFN- gamma , TGF- alpha , TGF- beta 1, TGF- beta 2, sCD14, LBP, and activated complement factor 5 (C5a) were sustained for periods of >48h. Systemic changes were characterized by elevated body temperature, induction of the acute phase protein synthesis of serum amyloid A and LBP, and a transient decrease in circulating neutrophils and lymphocytes. Together, these data demonstrate the capability of the mammary gland to mount a robust innate immune response to P. aeruginosa that is characterized by the induction of pro-inflammatory cytokines, complement activation, and increased levels of accessory molecules involved in Gram-negative bacterial recognition.

We hypothesized that differences in chicken macrophage responses to Salmonella enterica serovar Enteritidis (SE) and serovar Typhimurium (ST) played a role in preferential infection of eggs by SE compared with ST. To test this hypothesis, we determined bacterial phagocytosis and intracellular viability and macrophage nitric oxide (NO) production following in vitro infection with SE or ST in the presence or absence of interferon- gamma (IFN- gamma ). The effects of bacterial components, lipopolysaccharide (LPS), outer membrane proteins (OMP) and flagella, on NO production were also assessed. Our results showed: (1) in the presence or absence of IFN- gamma , the percentage macrophages phagocytizing SE and ST was similar; (2) the number of intracellular viable SE was significantly reduced compared with ST in the presence or absence of IFN- gamma ; (3) increased macrophage necrosis was seen in the presence of IFN- gamma and ST; (4) Salmonella infection acted synergistically with IFN- gamma in induction of nitric oxide production; and (5) in the absence of IFN- gamma , macrophages produced significantly greater NO following treatment with SE outer membrane protein or flagella compared with ST OMP or flagella, while in the presence of IFN- gamma significantly less NO was produced following treatment with SE-LPS compared with ST-LPS. These results suggest that differential responses of chicken macrophages to SE versus ST may result in increased macrophage death with ST, which could result in an increased inflammatory response as compared to SE.

To improve application of SDI in uneven-aged, mixed species stands present in large-scale forest inventories, trends in maximum SDI across diameter classes and species combinations were observed for eight common tree species of the United States. Additionally, the relationship between a stand's mean specific gravity of component trees and maximum SDI was explored. Results indicate that the maximum SDI that any particular species may attain is affected to varying degrees by the species composition of subject stands. A strong relationship was found between the mean specific gravity of all trees in a stand and the 99th percentile of the observed distribution of stand SDI's by classes of mean stand specific gravity. A model is proposed whereby the mean specific gravity of individual trees in a stand may serve as a predictor of a stand's maximum stocking potential, regardless of the stand's diameter distribution and species composition.

AN - 68535846; 16131153 AB - The objectives of this study were to determine total radioactive residues and chlorate residues in edible tissues of cattle administered at three levels of sodium [36Cl]chlorate over a 24-h period and slaughtered after a 24-h withdrawal period. Three sets of cattle, each consisting of a heifer and a steer, were intraruminally dosed with a total of 21, 42, or 63 mg of sodium [36Cl]chlorate/kg of body weight. To simulate a 24-h exposure, equal aliquots of the respective doses were administered to each animal at 0, 8, 16, and 24 h. Urine and feces were collected in 12-h increments for the duration of the 48-h study. At 24 h after the last chlorate exposure, cattle were slaughtered and edible tissues were collected. Urine and tissue samples were analyzed for total radioactive residues and for metabolites. Elimination of radioactivity in urine and feces equaled 20, 33, and 48% of the total dose for the low, medium, and high doses, respectively. Chlorate and chloride were the only radioactive chlorine species present in urine; the fraction of chlorate present as a percentage of the total urine radioactivity decreased with time regardless of the dose. Chloride was the major radioactive residue present in edible tissues, comprising over 98% of the tissue radioactivity for all animals. Chlorate concentrations in edible tissues ranged from nondetectable to an average of 0.41 ppm in skeletal muscle of the high-dosed animals. No evidence for the presence of chlorite was observed in any tissue. Results of this study suggest that further development of chlorate as a preharvest food safety tool merits consideration.

AN - 68506401; 15993540 AB - A suspected case of trichinellosis was identified in a single patient by the New Hampshire Public Health Laboratories in Concord, NH. The patient was thought to have become infected by consumption of muscle larvae (ML) in undercooked meat from a black bear killed in Plymouth, NH in October 2003 and stored frozen at -20 degrees C fro 4 months. In January 2004, a 600 g sample of the meat was thawed at 4 degrees C, digested in hydrochloric acid and pepsin, and larvae were collected by sedimentation. Intact, coiled, and motile ML were recovered (366 larvae per gram (l pg) of tissue), which were passed into mice and pigs. Multiplex PCR revealed a single 127 bp amplicon, indicative of Trichinella nativa. The Reproductive Capacity Index (RCI) for the T. nativa-Plymouth isolate in mice was 24.3. Worm burdens in the diaphragms of two 3-month-old pigs given 2,500 ML were 0.05 and 0.2l pg by 35 days post-inoculation, while 2.2 and 0.75 l pg were recovered from two 3-month-old pigs given 10,000 ML; no larvae were recovered from four 1-year-old pigs given 2,500 ML (n=2) or 10,000 ML (n=2). Viable larvae were also recovered from frozen black bear meat harvested at two additional locations, one in southern Ontario, Canada, and one in upstate New York, USA. Multiplex PCR using genomic DNA from these parasite samples demonstrated that both isolates were T. nativa. This is the first report of the freeze-resistant species, T. nativa, within the continental United States.

AN - 68505647; 15993000 AB - Control of Trichinella infection in U.S. pork has traditionally been accomplished by inspection of individual carcasses at slaughter or by post-slaughter processing to inactivate parasites. We propose that an alternative to individual carcass testing or processing can be used when pigs are raised in production systems where risk of exposure to Trichinella spiralis has been mitigated. Declines in prevalence of this parasite in U.S. domestic swine during the last 30 years, coupled with improvements in pork production systems, now allow Trichinella control to be shifted to the farm through implementation of specific pork production practices. Knowledge of risk factors for exposure of swine to T. spiralis was used to develop an objective audit of risk that can be applied to pork production sites. In a pilot study, 461 production site audits were performed by trained veterinary practitioners. The on-farm audit included aspects of farm management, bio-security, feed and feed storage, rodent control programs and general hygiene. Of the 461 production site audits, 450 audits (97.6%) indicated compliance with the required good production practices. These sites are eligible for certification under the U.S. Trichinae Certification Program and will be audited regularly to maintain that status. The described trichinae certification mechanism will establish a process for ensuring the Trichinella safety of swine, and ultimately food products derived from swine, at the production level.

Herbert Stone Nursery, a USDA Forest Service nursery, located in Central Point, OR, has completed a variety of production trials to adapt general cultural practices to its site. These trials resulted in changes which include: developing a strategy to maintain a high soil porosity through the application of organic matter and tillage measures; sowing seed earlier in the winter for 1 + 0 stocktypes; lowering seedbed densities from 267 seedlings/m super(2) (25 seedlings/ft super(2)) to between 161 and 195 seedlings/m super(2) (15 and 18 seedlings/ft super(2)); transplanting seedlings in early fall instead of spring; and developing a miniplug + 1 stocktype.

Fusarium, Cylindrocarpon, and Pythium are the most ubiquitous, whereas incidence of Phytophthora is mostly associated with coastal bareroot nurseries. All of these root pathogens are encouraged by water saturated soils or media. Seedlings infected with Fusarium, Phytophthora, or Pythium often appear chlorotic or necrotic with extensive root decay. Cylindrocarpon often causes serious root decay without shoot symptoms. The best approach to mitigate losses from these diseases is to use a holistic integrated pest management program. This program should combine chemical controls with cultural practices, particularly those that increase soil permeability and drainage and reduce potential sources of inoculum, especially by disinfesting seeds and containers reused for crops. In general, we found that seedlings meeting nursery specifications for outplanting on forest soil (proper height, root collar diameter, healthy shoot color, lack of disease symptoms) but having these disease organisms on their root systems perform as well as non-infected seedlings.

Evaluation of how seed source affects root system responses to soil conditions will allow seed sources to be matched to planting conditions. The root growth and hydraulic conductivity of three sources each of shortleaf, loblolly and longleaf pine seedlings were evaluated for 28days in a seedling growth system that simulated the planting environment. Across species, an increase in root-zone temperature alleviated limitations to root growth caused by water stress. In the coldest temperature, longleaf pine maintained a higher hydraulic conductivity compared to shortleaf and loblolly pine. Without water limitation, the root growth and hydraulic conductivity of shortleaf and loblolly pine were superior to that of longleaf pine, but as water availability decreased, the root growth of longleaf pine surpassed that of loblolly pine. Hydraulic conductivities of the seed sources differed, and differences were attributed to either new root growth, or an increase in the efficiency of the root system to transport water.

AN - 68908148; 16363176 AB - Boophilus microplus (Canestrini), collected from Starr County, Texas, were determined to be resistant to the organophosphorus acaricides coumaphos and diazinon. Initial bioassay results from wild-collected ticks produced a probit regression slope (SE) of 3.96 (0.22), which was different from that obtained from a susceptible reference population 6.97 (0.38). Resistance ratios (RRs) (95% CI) indicated that the population was resistant to coumaphos 3.6 (3.4-3.8), 5.0 (4.5-5.5), and 6.5 (5.4-7.7) at the LC50,90,99, respectively. A second collection of wild ticks made 12 d after all cattle in the infested pasture were treated with coumaphos produced a slope (SE) that was not significantly different from a susceptible laboratory reference population. A second bioassay found these ticks to be resistant to diazinon,RR (95%CI) = 7.1 (6.5-7.7),11.7 (10.3-13.3),17.7 (14.5-21.5) at the LC50,90,99, respectively. The slope (SE) generated from the diazinon bioassay with the resistant ticks was different than that of a reference strain, 2.98 (0.12) and 6.09 (0.35), respectively. The high-dose strategy used by the Cattle Fever Tick Eradication Program was able to eradicate coumpahos-resistant B. microplus after just two treatments of coumaphos, 12 d apart.

AN - 68647482; 16111797 AB - Growing epidemiological evidence of associations between mildly elevated plasma homocysteine with age-related cognitive impairment, neurodegenerative and cerebrovascular disease has stimulated interest in the role of homocysteine in neurological and neuropsychiatric disorders. Homocysteine is an intermediate in the folate, vitamin B12 and B6 dependent pathways of one-carbon and sulfur amino acid metabolism. Impairments of these pathways may cause CNS dysfunction by promoting the intracellular generation of homocysteine, which is postulated to have vasotoxic and neurotoxic properties. It might also inhibit the methylation of myelin basic protein and membrane phospholipids, or disrupt biogenic amine metabolism and many other vital CNS reactions. However, it is unclear which, if any, of these putative mechanisms underlies the epidemiological associations. Genetic mouse models of hyperhomocysteinemia suggest that the primary metabolic disturbances rather than homocysteine per se may be important in determining neurological outcomes. However, severe and early developmental abnormalities in these mice limit their usefulness for understanding the relation of hyperhomocysteinemia to adult CNS disorders. Pharmacologic and dietary studies on homocysteine in rodents have reported heightened neuronal sensitivity to neurotoxic insults, neurochemical abnormalities and cerebrovascular dysfunction. Such studies are consistent with a causal relationship, but they fail to distinguish between effects that might result from a dietary imbalance and those that might be caused by homocysteine per se. Future work should be directed towards refining these models in order to distinguish between the effects of homocysteine and its determinants on neurological and behavioral outcomes that represent different CNS disorders.

AN - 68559073; 16145203 AB - Locoweed poisoning has been reported in wildlife, but it is unknown whether mule deer (Odocoileius hemionus) are susceptible. In areas that are heavily infested with locoweed, deer and elk (Cervus elaphus nelsoni) have developed a spongiform encephalopathy, chronic wasting disease (CWD). Although these are distinct diseases, no good comparisons are available. The purpose of this study was to induce and describe chronic locoweed poisoning in deer and compare it with the lesions of CWD. Two groups of four mule deer were fed either a complete pelleted ration or a similar ration containing 15% locoweed (Oxytropis sericea). Poisoned deer lost weight and developed a scruffy, dull coat. They developed reluctance to move, and movement produced subtle intention tremors. Poisoned deer had extensive vacuolation of visceral tissues, which was most severe in the exocrine pancreas. Thyroid follicular epithelium, renal tubular epithelium, and macrophages in many tissues were mildly vacuolated. The exposed deer also had mild neuronal swelling and cytoplasmic vacuolation that was most obvious in Purkinje cells. Axonal swelling and dystrophy was found in many white tracts, but it was most severe in the cerebellar peduncles and the gracilis and cuneate fasciculi. These findings indicate that deer are susceptible to locoweed poisoning, but the lesions differ in severity and distribution from those of other species. The histologic changes of locoweed poisoning are distinct from those of CWD in deer; however, the clinical presentation of locoweed poisoning in deer is similar. Histologic and immunohistochemical studies are required for a definitive diagnosis.

AN - 68505475; 15993915 AB - Mutational analysis was conducted to investigate the role of the nucleotide sequences flanking the stem-loop palindromic structure at the origin of DNA replication of porcine circovirus type 1 (PCV1) with respect to self-DNA replication and progeny virus generation. The results demonstrated that the A-rich sequence to the left of the palindrome is non-essential for virus replication. Although a set of four hexanucleotide (H) sequences to the right of the palindrome (organized in two tandem repeats: the proximal H1/H2 and the distal H3/H4) are binding sites for the viral Rep-associated proteins in vitro, only a proximal tandem (H/H or h-like/H) is essential for PCV1 DNA replication. In the presence of H1/H2, mutations engineered into H3/H4 were preserved in the progeny viruses. Mutations engineered into H1/H2 were invariably deleted so that the downstream H3/H4 was placed next to the palindrome. Viral genome with mutations engineered into both H1/H2 and H3/H4 underwent extensive nucleotide reorganization to yield progeny viruses containing either H3/H4, h-like/H4, or h-like/H3/H4 sequences.

AN - 68480524; 16103192 AB - In early 2004, an H5N2 avian influenza virus (AIV) that met the molecular criteria for classification as a highly pathogenic AIV was isolated from chickens in the state of Texas in the United States. However, clinical manifestations in the affected flock were consistent with avian influenza caused by a low-pathogenicity AIV and the representative virus (A/chicken/Texas/298313/04 [TX/04]) was not virulent for experimentally inoculated chickens. The hemagglutinin (HA) gene of the TX/04 isolate was similar in sequence to A/chicken/Texas/167280-4/02 (TX/02), a low-pathogenicity AIV isolate recovered from chickens in Texas in 2002. However, the TX/04 isolate had one additional basic amino acid at the HA cleavage site, which could be attributed to a single point mutation. The TX/04 isolate was similar in sequence to TX/02 isolate in several internal genes (NP, M, and NS), but some genes (PA, PB1, and PB2) had sequence of a clearly different origin. The TX/04 isolate also had a stalk deletion in the NA gene, characteristic of a chicken-adapted AIV. By analyzing viruses constructed by in vitro mutagenesis followed by reverse genetics, we found that the pathogenicity of the TX/04 virus could be increased in vitro and in vivo by the insertion of an additional basic amino acid at the HA cleavage site and not by the loss of a glycosylation site near the cleavage site. Our study provides the genetic and biologic characteristics of the TX/04 isolate, which highlight the complexity of the polygenic nature of the virulence of influenza viruses.

AN - 68463354; 16091599 AB - Comprehensive assessment of the total greenhouse gas (GHG) budget of reduced tillage agricultural systems must consider emissions of nitrous oxide (N2O) and methane (CH4), each of which have higher global warming potentials than carbon dioxide (CO2). Tillage intensity may also impact nitric oxide (NO) emissions, which can have various environmental and agronomic impacts. In 2003 and 2004, we used chambers to measure N2O, CH4, and NO fluxes from plots that had been managed under differing tillage intensity since 1991. The effect of tillage on non-CO2 GHG emissions varied, in both magnitude and direction, depending on fertilizer practices. Emissions of N2O following broadcast urea (BU) application were higher under no till (NT) and conservation tillage (CsT) compared to conventional tillage (CT). In contrast, following anhydrous ammonia (AA) injection, N2O emissions were higher under CT and CsT compared to NT. Emissions following surface urea ammonium nitrate (UAN) application did not vary with tillage. Total growing season non-CO2 GHG emissions were equivalent to CO2 emissions of 0.15 to 1.9 Mg CO2 ha(-1) yr(-1) or 0.04 to 0.53 Mg soil-C ha(-1) yr(-1). Emissions of N2O from AA-amended plots were two to four times greater than UAN- and BU-amended plots. Total NO + N2O losses in the UAN treatment were approximately 50% lower than AA and BU. This study demonstrates that N2O emissions can represent a substantial component of the total GHG budget of reduced tillage systems, and that interactions between fertilizer and tillage practices can be important in controlling non-CO2 GHG emissions.

AN - 68460205; 16091621 AB - Applications of animal manures have increased soil test P values in many parts of the USA and thus increased the risk that soil P will be transferred to surface water and decrease water quality. To continue farming these areas, landowners need tools to reduce the risk of P losses. A field experiment was conducted near Kurten, TX, on a Zulch fine sandy loam (thermic Udertic Paleustalfs) with Bray-1 P values exceeding 3000 mg P kg(-1) soil (dry wt.) in the A(p) horizon to evaluate the effectiveness of soil amendments for reducing soil test P values. Soils were amended annually from 1999 to 2001 with 1.5 and 5.0 Mg gypsum ha(-1), 1.4 Mg alum ha(-1), or 24.4 Mg ha(-1) of waste paper product high in Al alone or in combination with 1.5 Mg gypsum ha(-1) and/or 1.4 Mg alum ha(-1). These treatments supplied a maximum of 225 and 1163 kg ha(-1) yr(-1) of Al and Ca, respectively. Soil Bray-1 P and dissolved reactive P levels were monitored from 1999 to 2004. None of the soil amendment treatments affected Bray-1 P values. Only annual additions of 5.0 Mg gypsum ha(-1) from 1999 to 2001 significantly reduced soil dissolved reactive P. Dissolved reactive P levels reached minimal levels after two applications of 5.0 Mg gypsum ha(-1) but increased in 2003 and 2004. These results indicate that soil dissolved reactive P levels can be reduced if sufficient amounts of gypsum were added to supply Ca in amounts similar to the soil test P values.

AN - 68030837; 16018890 AB - The presence of large amounts of Se-laden agricultural drainage sediment in the San Luis Drain, Central California, poses a serious toxic threat to wildlife in the surrounding environment. Effective management of the drainage sediment becomes a practical challenge because the sediment is polluted with high levels of Se, B, and salts. This two-year field study was conducted to identify the best plant species that are salt and B tolerant and that have a superior ability of volatilizing Se from drainage sediment. The drainage sediment was mixed with clean soil, and vegetated with salado alfalfa (Medicago sativa 'salado'), salado grass (Sporobulus airoides 'salado'), saltgrass-turf (Distichlis spp. 'NYPA Turf'), saltgrass-forage (Distichlis spicata (L.) Greene), cordgrass (Spartina patens 'Flageo'), Leucaenia (Leucaena leucocephola), elephant grass (Pennistum purpureum), or wild type-Brassica (Brassica spp.). Results show that elephant grass produced the greatest amount of biomass and accumulated highest concentrations of B. Highest concentrations of Se, S, and Cl were observed in wild-type Brassica. Biogenic volatilization of Se by plants and soil microbes was greater in summer. Among the treatments, the mean daily rates of Se volatilization (microg Se m(-2)d(-1)) were wild-type Brassica (39) > saltgrass-turf (31) > cordgrass (27) > saltgrass forage (24) > elephant grass (22) > salado grass (21) > leucaenia (19) > salado alfalfa (14) > irrigated bare soil (11) > non-irrigated bare soil (6). Overall, rates of Se volatilization in drainage sediment were relatively low due to high levels of sulfate. To manage Se in drainage sediment by phytoremediation, the biological volatilization process needs to be enhanced substantially under field conditions.

A benefit of these ditches is contaminant mitigation of agricultural storm runoff. This study determined bifenthrin and lambda-cyhalothrin (two pyrethroid insecticides) partitioning and retention in ditch water, sediment, and plant material as well as estimated necessary ditch length required for effective mitigation. A controlled-release runoff simulation was conducted on a 650-m vegetated drainage ditch in the Mississippi Delta, USA. Bifenthrin and lambda-cyhalothrin were released into the ditch in a water-sediment slurry. Samples of water, sediment, and plants were collected and analyzed for pyrethroid concentrations. Three hours following runoff initiation, inlet bifenthrin and lambda-cyhalothrin water concentrations ranged from 666 and 374 mu g/L, respectively, to 7.24 and 5.23 mu g/L at 200 m downstream. No chemical residues were detected at the 400-m sampling site. A similar trend was observed throughout the first 7 d of the study where water concentrations were elevated at the front end of the ditch (0-25 m) and greatly reduced by the 400-m sampling site. Regression formulas predicted that bifenthrin and lambda-cyhalothrin concentrations in ditch water were reduced to 0.1% of the initial value within 280 m. Mass balance calculations determined that ditch plants were the major sink and/or sorption site responsible for the rapid aqueous pyrethroid dissipation. By incorporating vegetated drainage ditches into a watershed man-agement program, agriculture can continue to decrease potential non-point source threats to downstream aquatic receiving systems. Overall results of this study illustrate that aquatic macrophytes play an important role in the retention and distribution of pyrethroids in vegetated agricultural drainage ditches.

Although great egrets captured most baitfish/minute, captures/strike were nearly identical among the three wading bird species. American gizzard shad Dorosoma cepedianum, goldfish Carassius auratus, and giant water bugs Hemiptera: Belostomatidae were collected from the gastro-intestinal tract of great blue herons. Only golden shiners Noremgonus crysoleucas and goldfish were found in great egrets. We found dragonflies Odonata, golden shiners, green sunfish Lepomis cyanellus, and water bugs in little blue herons. In contrast to other birds collected, snowy egrets E. thula were found to contain mosquito fish Gambusia affinis. Among 2,742 teleost otoliths recovered from collected great blue herons, great egrets, and little blue herons, most otoliths belonged to the Cyprinidae family (including the baiffishes). Surveyed farm managers use various auditory and visual stimuli to disperse fish-eating birds from their farms. Surveyed baitfish farmers suggested that the average cost of their annual bird harassment program was $11,580 at relatively small farms (< 202 ha) and $104,560 at relatively large X 202 ha) baitfish aquaculture facilities. We estimated the replacement cost of baitfish consumed by wading buds based upon their daily food requirements, the food habits of herons and egrets at baiffish farms, the hypothetical abundance of wading birds at a particular baitfish farm (relative to survey results), the duration of herons and egrets reported by farm managers, and current baitfish market values.

In the fragmented agroecosystem of northwest Mississippi, placement of drop-pipe structures has been used as a restoration technique for abating gully erosion along stream banks. These actions have formed small herbaceous and woody habitat extensions into former agricultural lands. We quantified species relative abundances, species richness, and evenness of avian nest predators and a brood parasite within four categories of constructed habitat resulting from drop-pipe installation. Differences in the abundance of two nest predators, cotton mouse (Peromyscus gossypinus) and blue jay (Cyanocitta cristata), were observed among constructed habitats. However, relative abundances of other predators such as common grackle (Quiscalusquiscula), American crow (Corvus brachyrhynchos), and hispid cotton rat (Sigmodon hispidus), and the obligate brood parasite brown-headed cowbird (Molothrus ater) did not differ among four habitat categories. Although species richness, abundance, and evenness of potential nest predators were generally similar among the constructed habitats, predator species composition varied, suggesting that these habitats supported different predator communities. This difference is important because as each predator species is added to or deleted from the community, variation may occur in the framework of prey search methods, predator strategies, and potentially overall predation pressure. We suggest that land managers using drop-pipes as part of stream restoration projects allow for the development of the constructed habitat with the largest area and greatest vegetative structure.

Adipose tissue has been the focus of efforts to identify candidate genes. Perilipin is a major protein found in adipocytes, and perilipin knockout mice are lean and resistant to diet-induced obesity. OBJECTIVE: The objective of the study was to examine the association of several polymorphisms at the perilipin (PLIN) locus with obesity and weight reduction in response to a low-energy diet in obese patients. DESIGN: This study was a 1-yr randomized (depending on the PLIN genotype) trial with three follow-up evaluations. SETTING: The study was conducted at a university research center. SUBJECTS: One hundred fifty obese patients (body mass index, 42 plus or minus 8 kg/m super(2)) at baseline and 48 patients who completed the dietary follow-up treatment for weight loss participated in the study. INTERVENTIONS: Subjects completed a 1-yr low-energy diet. MAIN OUTCOMES: Measurements: Body weight (BW) at baseline and 3, 6, and 12 months was measured. RESULTS: The minor A-allele at the PLIN 11482G>A polymorphism was associated with lower baseline BW. Moreover, we found a gene-diet interaction (P = 0.015) between this polymorphism and weight loss in patients that completed the 1-yr dietary treatment. Diet resulted in significant decreases in BW (from 114.3 plus or minus 3.9 kg at baseline to 105.5 plus or minus 3.5 kg at 1 yr; P lineal trend, 0.020) in GG patients (n = 33). Conversely, carriers of the minor A allele (n = 15) did not show significant changes in BW (from 105.0 plus or minus 4.6 kg at baseline to 104.3 plus or minus 4.4 kg at 1 yr; P lineal trend, 0.985). This gene-diet interaction remained statistically significant, even after adjustment for differences in BW at baseline and for other potential confounders. CONCLUSIONS: PLIN11482A carriers were resistant to weight loss, suggesting that this polymorphism may predict outcome of BW reduction strategies based on low-energy diets.

Conversion of poultry manure to value-added granular activated carbons for environmental remediation can be such a solution. The objective of this study was to compare the effectiveness of poultry manure-based carbons for the adsorption of selected metal ions (copper, cadmium, nickel, zinc) from solutions containing individual ions or the four metal ions present together. Adsorption properties for poultry manure-based carbons were compared with those of two commercial carbons, PR RF and Minotaur, and carbons from three traditional precursors, coal, coconut and wood. Pelletized samples were pyrolyzed at 700 °C for 1 h followed by 800 °C steam activation at 1, 3 and 5 mL min-1 water flow rate, for 30 and 45 min, under nitrogen. The carbon's ability to adsorb the metals was influenced by the activation strategy, increasing for longer activation times and higher water flow rates, in the presence of a single metal solution. Saturation conditions were achieved at 20 mM and, at 5 mM, almost all metal ion in solution was adsorbed, except for nickel. Carbons showed similar affinity towards copper, cadmium and zinc, individually. However, when in competition, at 5 mM of each metal, manure-based carbons showed a preference for Cu2+ followed by Zn2+ and Cd2+. Poultry manure-based carbons outperformed all reference carbons and PR RF, and, except for Ni2+, Minotaur was also outperformed.

Studies were conducted to elucidate the impact of DAPG and its co-product 2,4,6-trihydroxyacetophenone (THA) on the production of Pseudomonas fluorescens for biological control. Increasing DAPG from 0.1 g/l to 0.5 g/l and THA from 0.05 g/l to 0.5 g/l significantly inhibited the growth and lowered the yield of viable bacteria in liquid cultures. On further examination of these metabolites applied in seed coatings, levels of DAPG and THA exceeding 0.05 mg/g seed significantly reduced wheat germination percentages. The three-way interaction of DAPG, THA, and culture medium ingredients was significant, and greatest seed germination loss (40-50%) was observed when 0.5 mg DAPG and 0.25 mg THA were combined in a coating of 0.5 ml culture medium per gram of seed. Based on the results of Biolog GN microplate, flask, and fermentor screens of C sources, proline was found to optimize the viable cell yields of the P. fluorescens strains tested. The combination of proline with glucose and urea as C and N sources in growth media could be optimized to minimize DAPG production and maximize the vitality of P. fluorescens Q8R1-96 and Q69c-80:miniTn5:phl20 (DAPG over-producer). In production cultures, the proline supply rate offers a potentially useful means to optimize the biological control agent yield and quality.

For soil moisture monitoring, gravimetric soil moisture sampling is reliable; however, it requires a significant effort to gather and process samples. Portable impedance probes serve as a valuable alternative to destructive gravimetric sampling. These probes measure the dielectric properties of the soil-water-air mixture from which we can infer the volumetric soil moisture. As part of recent large-scale experiments in the summers of 2002 and 2003, three different methods for calibrating impedance probes were investigated with the support of coincident gravimetric samples. Field specific calibration improved the accuracy of the probe from greater than +/-5% volumetric soil moisture (using the generalized calibration) to less than +/-4%. In addition, a significant amount of bias (2%) was eliminated. It was also determined that field specific calibration removes a bias due to bulk density variations. Based upon these results it was concluded that the generalized calibration is adequate for estimation of diverse conditions. For studies with more stringent accuracy requirements, field specific calibration is necessary because of reduced bias and error.

The restoration and creation of wetlands for mitigation purposes is becoming common in the Southeast. Understanding the effects of these restoration efforts on wetland flora and fauna is thus becoming increasingly important. Because bats (Order: Chiroptera) consist of many species that are of conservation concern and are commonly associated with wetland and riparian habitats in the Southeast (making them a good general indicator for the condition of wetland habitats), we monitored bat activity over restored and reference Carolina bays surrounded by pine savanna (Pinus spp.) or mixed pine-hardwood habitat types at the Savannah River Site in South Carolina. In order to determine how wetland restoration efforts affected the bat community, we monitored bat activity above drained Carolina bays pre- and post-restoration. Our results indicate that bat activity was greater over reference (i.e., undrained) than drained bays prior to the restorative efforts. One year following combined hydrologic and vegetation treatment, however, bat activity was generally greater over restored than reference bays. Bat activity was also greater over both reference and restored bays than in random, forested interior locations. We found significantly more bat activity after restoration than prior to restoration for all but one species in the treatment bays, suggesting that Carolina bay restoration can have almost immediate positive impacts on bat activity.

The diversity of new destinations raises questions about forces attracting migrants to rural areas and links between economic structural change and Hispanic population growth. Our conceptual framework applies dual labor market theory to the meat processing industry, a sector whose growing Hispanic labor force offers an illustrative case study for analyzing how labor demand influences demographic change. We document the industry's consolidation, concentration, increased demand for low-skilled labor, and changing labor force composition over three decades. We then position meat processing within a broader analysis that models nonmetropolitan county Hispanic population growth between 1980 and 2000 as a function of changes in industrial sector employment share and nonmetro county economic and demographic indicators. We find that growth in meat processing employment exhibits the largest positive coefficient increase in nonmetro Hispanic population growth over two decades and the largest impact of all sectors by 2000.

We measured surface runoff volumes and nutrient concentrations and loads in a riparian buffer system consisting of (moving down slope from the field) a grass strip, a managed forest, and an unmanaged forest. The managed forest consisted of sections of clear-cut, thinned, and mature forest. The mature forest had significantly lower flow-weighted concentrations of nitrate, ammonium, total Kjeldahl N (TKN), sediment TKN, total N (nitrate + TKN), dissolved molybdate reactive P (DMRP), total P, and chloride. The average buffer represented the conditions along a stream reach with a buffer system in different stages of growth. Compared with the field output, flow-weighted concentrations of nitrate, ammonium, DMRP, and total P decreased significantly within the buffer and flow- weighted concentrations of TKN, total N, and chloride increased significantly within the buffer. All loads decreased significantly from the field to the middle of the buffer, but most loads increased from the middle of the buffer to the sampling point nearest the stream because surface runoff volume increased near the stream. The largest percentage reduction of the incoming nutrient load (at least 65% for all nutrient forms) took place in the grass buffer zone because of the large decrease (68%) in flow. The average buffer reduced loadings for all nutrient species, from 27% for TKN to 63% for sediment P. The managed forest and grass buffer combined was an effective buffer system.

One-day-old infectious bursal disease virus (IBDV) and infectious bronchitis virus (IBV) antibody positive commercial broilers and 1-day-old antibody negative specific-pathogen-free (SPF) broilers were orally gavaged with proventricular homogenates produced from the proventriculi of broilers with proventriculitis. At 7 and 14 days, both commercial and SPF broilers had enlargement of the proventriculus with necrosis of the glandular epithelium and lymphocytic infiltrates in the proventricular glands. SPF broilers exposed to the proventricular homogenates developed infectious bursal disease, and IBDV was detected by reverse transcriptase-polymerase chain reaction (RT-PCR). They also were positive by RT-PCR to IBV and developed nephritis. Commercial broilers developed mild nephritis but not bursal disease and were negative for IBDV and positive for IBV by RT-PCR. Both homogenate-inoculated commercial and SPF chickens were negative for reovirus and Newcastle disease virus by RT-PCR and variably positive for adenovirus by PCR. Bacteria were not identified in histologic sections, nor were they isolated from affected proventriculi. Indirect fluorescent antibody assay using convalescent sera detected intracytoplasmic staining in the proventricular glandular epithelial cells. Examination of thin sections of proventriculi using electron microscopy identified virus-like particles approximately 120 nm in diameter within the cytoplasm of these cells at 7 days after inoculation. Passage of proventricular homogenate filtrates in chicken embryos for virus isolation caused stunting, and allantoic fluid from these eggs was positive for IBV by RT-PCR.Original Abstract: Reproduccion de proventriculitis en pollos de engorde comerciales y libres de patogenos especificos.Mediante la reproduccion experimental de la enfermedad, se estudio la proventriculitis en pollos de engorde. Homogeneizados de proventriculo generados de los proventriculos de pollos de engorde con proventriculitis, fueron administrados con sonda por la via oral, a pollos de engorde comerciales de un dia de edad con anticuerpos contra el virus de la enfermedad infecciosa de la bolsa y virus de bronquitis infecciosa, asi como a pollos de engorde libres de patogenos especificos negativos a anticuerpos. Tanto los pollos de engorde comerciales como los libres de patogenos especificos mostraron un aumento de tamano del proventriculo con necrosis del epitelio glandular e infiltracion linfocitica en las glandulas proventriculares a los 7 y 14 dias postenores a la inoculacion. Los pollos de engorde libres de patogenos especificos expuestos a los homogeneizados de proventriculo, desarrollaron enfermedad infecciosa de la bolsa detectandose a traves de reaccion en cadena por la polimerasa-transcriptasa reversa (por sus siglas in Ingles RT-PCR). A su vez, estas aves resultaron positivas a la prueba RT-PCR para bronquitis infecciosa y desarrollaron nefritis. Los pollos de engorde comerciales desarrollaron nefritis leve, pero no enfermedad infecciosa de la bolsa, resultando negativos para el virus de la enfermedad infecciosa de la bolsa y positivos para bronquitis infecciosa mediante la prueba RT-PCR. Tanto los pollos de engorde comerciales como los libres de patogenos especificos resultaron negativos para reovirus y el virus de la enfermedad de Newcastle por medio de la prueba RT-PCR, mientras que para adenovirus la positividad fue variable a la prueba de PCR. No fue posible la identificacion de bacterias en los cortes histologicos ni su aislamiento de los proventriculos afectados.

Trace amount of endogenous trehalose was detected in flowering plants, and the trehalose biosynthetic pathway was essential for embryo maturation in Arabidopsis. Conversely, exogenous trehalose was toxic to higher plants and severely curtailed root and shoot growth. In the current study, 30 mM trehalose was added to 2-week-old liquid cultures containing Arabidopsis thaliana (Columbia ecotype) seedlings. Densely stained granular particles were detected in the extracellular space of cotyledons and roots of trehalose-treated seedlings using transmission electron microscopy. Expression levels of 91 transcripts were altered by 1-6 h of trehalose treatment using DNA microarray analysis, and 65 of these encoded either known proteins or putative proteins with known functions. The exogenous trehalose treatment altered transcript levels of transcription factors, cell wall modification, nitrogen metabolism, and stress-related, defense-related, and fatty acid biosynthesis genes. Many of the transcripts altered by exogenous trehalose treatment were associated with the ethylene and methyl jasmonate-signaling pathways. The above findings suggested that trehalose, or metabolites derived from trehalose, are important regulators of plant gene expression in higher plants.

Knowledge of the evolution of these agents is important in understanding their bioloev. The availability of the first complete phytoplasma and several partial spiroplasma and phytoplasma genome sequences made possible an investigation of evolutionary relationships between phytopathogenic mollicutes and other micro-organisms, especially Gram-positive bacteria, using a comparative genomics approach. Genome data from a total of 41 bacterial species were used in the analysis. Sixty-one conserved proteins were selected from each species for the construction of a hypothetical phylogenetic tree. The genes encoding these selected proteins are among a core of genetic elements that constitute a hypothetical minimal genome. The proteins were concatenated into five superproteins according to their functional categories, and phylogenetic trees were reconstructed using distance, parsimony and likelihood methods. Phylogenetic trees based on the five sets of concatenated proteins were congruent in both clade topology and relative branching length. Spiroplasma kunkelii and phytoplasmas clustered together with other mollicutes, forming a monophyletic group. Phytoplasmas diverged from spiroplasmas and mycoplasmas at early stages in the evolution of mollicutes. Branch lengths on the phylogenetic trees were noticeably longer in the Mollicutes clade, suggesting that the genes encoding the five sets of proteins evolved at a greater rate in this clade than in other clades. This observation reinforces the concept that mollicutes have rapidly evolving genomes.

The goal of this study was to combine fuel maps, based on data from the Forest Inventory and Analysis (FIA) program of the USDA Forest Service, with real-time atmospheric data for the creation of a more dynamic index of fire danger. Results indicated fuel loadings and moisture could be estimated for specific points on a meteorological modeling grid network (4 x 4 km; based on FIA's strategic-scale fuel inventory and atmospheric data) enabling the current assessment and 1- to 2-day prediction of fire danger as well as refined understanding of fire danger across forest ecosystems.

Varying topsoil depth may influence reclamation success. This study assessed the long-term (24 years) effects of four topsoil replacement depths (0, 20, 40, and 60 cm) on plant community attributes (species richness, diversity, canopy cover, and production) and soil characteristics [organic carbon (C), total nitrogen (N), available phosphorus (P), pH, soluble cations, electrical conductivity (EC), and cumulative water infiltration]. Species richness and diversity were highest at the 0 cm topsoil depth and lowest at the 60 cm topsoil depth. Percent canopy cover of grasses was highest (25%) at 60 cm and lowest (15%) at 0 cm topsoil depth. Percent forb cover was highest (6%) at the 0 cm depth and lowest (2%) at 60 cm topsoil depth. Seeded species cover was highest (12%) at the 40 cm depth, but was not significantly different from the other depths. Aboveground biomass was similar between the 40 (727 kg ha super(-1)) and 60 cm (787 kg ha super(-1)) topsoil depths and higher than the 0 (512 kg ha super(-1)) and 20 cm (506 kg ha super(-1)) replacement depths. Plant species richness and diversity decreased with increasing topsoil depth, while biomass increased. Organic C mass in the soil profile (75 cm) was greatest in the 60 cm topsoil replacement (18.7 Mg C ha super(-1)) and lowest in the 0 and 20 cm treatments (11.3 and 10.5 Mg C ha super(-1), respectively). N mass (75 cm profile) exhibited a similar pattern with 60 cm of topsoil having the highest (1.9 Mg N ha super(-1)) and the 0 and 20 cm the lowest (0.8 Mg N ha super(-1) and 0.9 Mg N ha super(-1), respectively). Cumulative water infiltration was highest (134 mm) for the 40 cm topsoil depth followed by 60 cm (116 mm), and lowest (61 mm) for the 0 cm treatment. Soil N, organic C, and infiltration data indicate topsoil replacement depths of 40 and 60 cm provide the best nutrient status and water storage potential for sustainable reclamation. Placement of shallow topsoil replacement depths should be carefully planned to ensure topsoil thickness is adequate to sustain a vegetative community capable of protecting the soil surface against erosion. Variable topsoil replacement depths can be used in reclamation to manipulate plant community characteristics and create a mosaic of vegetation types. However, the reduced vegetation cover observed at the shallower topsoil depths may not protect against soil erosion; therefore, using variable topsoil depth replacement as a reclamation practice will require careful planning and implementation.

Purified VSH-1 virions are noninfectious, contain random 7.5-kb fragments of the bacterial genome, and mediate generalized transduction of B. hyodysenteriae cells. In order to identify and sequence genes of this novel gene transfer agent (GTA), proteins associated either with VSH-1 capsids or with tails were purified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The N-terminal amino acid sequences of 11 proteins were determined. Degenerate PCR primers were designed from the amino acid sequences and used to amplify several VSH-1 genes from B. hyodysenteriae strain B204 DNA. A lambda clone library of B. hyodysenteriae B204 DNA was subsequently screened by Southern hybridization methods and used to identify and sequence overlapping DNA inserts containing additional VSH-1 genes. VSH-1 genes spanned 16.3 kb of the B. hyodysenteriae chromosome and were flanked by bacterial genes. VSH-1 identified genes and unidentified, intervening open reading frames were consecutively organized in head (seven genes), tail (seven genes), and lysis (four genes) clusters in the same transcriptional direction. Putative lysis genes encoding endolysin (Lys) and holin proteins were identified from sequence and structural similarities of their translated protein products with GenBank bacteriophage proteins. Recombinant Lys protein hydrolyzed peptidoglycan purified from B. hyodysenteriae cells. The identified VSH-1 genes exceed the DNA capacity of VSH-1 virions and do not encode traditional bacteriophage early functions involved in DNA replication. These genome properties explain the noninfectious nature of VSH-1 virions and further confirm its resemblance to known prophage-like, GTAs of other bacterial species, such as the GTA from Rhodobacter capsulatus. The identification of VSH-1 genes will enable analysis of the regulation of this GTA and should facilitate investigations of VSH-1-like prophages from other Brachyspira species.

Predictions from a stand-growth simulator are incorporated into multiple nomograms that graphically display postthinning responses of various financial and biological response variables (mean annual increment, piece size, final harvest cost, total wood cost, and net present value). A customized ArcView GIS computer interface (ThinME) displays multiple nomograms and serves as a tool for forest managers to balance a variety of competing objectives when developing commercial thinning prescriptions. ThinME provides a means to evaluate simultaneously three key questions about commercial thinning: (1) When should thinning occur? (2) How much should be removed? and (3) When should the final harvest occur, to satisfy a given set of management objectives?.

Colonization of the intestinal tract is a necessary precursor to the invasion of reproductive organs and subsequent deposition inside eggs laid by infected hens, but the relationship between the persistence of Salmonella in the intestinal tract and the likelihood of egg contamination has been uncertain. In this study, groups of laying hens were inoculated with large oral doses of strains of Salmonella Enteritidis and Salmonella Heidelberg, including variants of the original parent strains that had been reisolated from eggs laid by infected hens in a prior study. The shedding of Salmonella in voided feces was monitored for 6 wk postinoculation, and all eggs laid by infected hens between 5 and 22 days postinoculation were cultured for Salmonella in their contents. The mean duration of fecal shedding was significantly longer for the previously passaged Salmonella strains (26.7 days) than for the original parent strains (17.5 days), and the passaged strains caused a significantly higher frequency of egg contamination (6.4%) than did the parent strains (3.3%). However, the duration of fecal shedding and the frequency of egg contamination were not correlated for any of the Salmonella Enteritidis or Salmonella Heidelberg strains.Original Abstract: Relacion entre la duracion de la eliminacion por via fecal y la produccion de huevos contaminados provenientes de ponedoras comerciales infectadas con cepas de Salmonella Enteritidis y Salmonella Heidelberg.La contaminacion de huevos por Salmonella Enteritidis ha permanecido como un problema significativo de salud publica por cerca de dos decadas, y Salmonella Heidelberg ha sido recientemente implicada en enfermedades humanas transmitidas por el consumo de huevos. La colonizacion del tracto intestinal es un precursor necesario para la invasion de los organos reproductivos y la subsiguiente deposicion en el interior de los huevos provenientes de ponedoras comerciales infectadas. Sin embargo, es incierta la relacion existente entre la persistencia de Salmonella en el tracto intestinal y la probabilidad de la contaminacion del huevo. En este estudio se inocularon grupos de ponedoras comerciales por via oral con dosis elevadas de cepas de Salmonella Enteritidis y Salmonella Heidelberg, incluyendo cepas variantes de cepas originales re-aisladas a partir de huevos de ponedoras comerciales infectadas en un estudio anterior. Se evaluo la eliminacion de Salmonella a traves de las heces durante 6 semanas posteriores a la inoculacion, y se realizo cultivo bacteriologico en la totalidad de los huevos provenientes de ponedoras infectadas entre 5 y 22 dias posteriores a la inoculacion. La duracion promedio de la eliminacion de Salmonella a traves de las heces fue significativamente mayor en las cepas de Salmonella re-aisladas con anterioridad (26.7 dias) al ser comparadas con las cepas originales (17.5 dias), y las cepas re-aisladas ocasionaron un numero significativamente mayor de huevos contaminados (6.4%) al ser comparadas con las cepas originales (3.3%). Sin embargo, no se observo una correlacion entre la duracion de la eliminacion de Salmonella en las heces y la frecuencia de la contaminacion de huevos en ninguna de las cepas de Salmonella Enteritidis o Salmonella Heidelberg empleadas.Abbreviations: BG = brilliant green; TS = tryptone soya JF - Avian Diseases AU - Gast, R K AU - Guard-Bouldin, J AU - Holt, P S AD - United States Department of Agriculture, Agricultural Research Service, Egg Safety and Quality Research Unit, Russell Research Center, Athens, GA 30605 Y1 - 2005/09// PY - 2005 DA - Sep 2005 SP - 382 EP - 386 PB - American Association of Avian Pathologists, Inc., 382 West Street Road New Bolton Center Kennett Sq.

Methods and Results:The 16S-23S rRNA spacer regions of 19 Edw. ictaluri and four Edw. tarda isolates from four geographical regions were amplified by PCR with primers complementary to conserved sequences within the flanking 16S-23S rRNA coding sequences. Two products were generated from all isolates, without interspecies or intraspecific size polymorphisms. Sequence analysis of the amplified fragments revealed a smaller ISR of 350 bp, which contained a gene for tRNA super(Glu), and a larger ISR of 441 bp, which contained genes for tRNA super(Ile) and tRNA super(Ala). The sequences of the smaller ISR of different Edw. ictaluri isolates were essentially identical to each other. Partial sequences of larger ISR from several Edw. ictaluri isolates also revealed no differences from the one complete Edw. ictaluri large ISR sequence obtained. The sequences of the smaller ISR of Edw. tarda were 97% identical to the Edw. ictaluri smaller ISR and the larger ISR were 96-98% identical to the Edw. ictaluri larger ISR sequence. The Edw. tarda isolates displayed limited ISR sequence heterogeneity, with greater than or equal to 97% sequence identity among isolates for both small and large ISR. Conclusions:There is a high degree of size and sequence similarity of 16S-23S ISR both among isolates within Edw. ictaluri and Edw. tarda species and between the two species. Significance and Impact of the Study:Our results confirm a close genetic relationship between Edw. ictaluri and Edw. tarda and the relative homogeneity of Edw. ictaluri isolates compared with Edw. tarda isolates. Because no differences were found in ISR sequences among Edw. ictaluri isolates, sequence analysis of the ISR will not be useful to distinguish isolates of Edw. ictaluri. However, we identified restriction sites that differ between ISR sequences of Edw. ictaluri and Edw. tarda, which will be useful in distinguishing the two species.

STUDY DESIGN: A 30-year follow-up of the original participants in the Newton Girls Study, a prospective study of development in a cohort of girls followed through menarche, provided data on premenarcheal relative weight and overweight (BMI >85th percentile), prospectively obtained age at menarche, self-reported adult BMI, overweight (BMI > 25), obesity (BMI > 30) and, for a subset of participants, percentage body fat by dual-energy x-ray absorptiometry. RESULTS: Of the 448 women who participated in the adult follow-up at a mean age of 42.1 years (SD: 0.76 years), 307 had childhood data with which to characterize premenarcheal and menarcheal weight status and age at menarche. After a follow-up of 30.1 years (SD: 1.4 years), reported BMI was 23.4 (4.8), 28% were overweight, and 9% were obese. In multivariate linear and logistic-regression analyses, almost all of the influence on adult weight status was a result of premenarcheal weight status (model R super(2) = 0.199). Inclusion of a variable to reflect menarcheal timing provided very little additional information (model R super(2) = 0.208). Girls who were overweight before menarche were 7.7 times more likely to be overweight as adults (95% confidence interval: 2.3, 25.8), whereas early menarche (at less than or equal to 12 years of age) did not elevate risk (odds ratio: 1.3, 95% confidence interval: 0.66, 2.43). A similar pattern of results was observed when percentage body fat in adulthood was evaluated. CONCLUSIONS: The apparent influence of early maturation on adult female overweight is largely a result of the influence of elevated relative weight on early maturation. Interventions to prevent and treat overweight should focus on girls before they begin puberty.

In addition, the sensitivity of the assay with this element was compared to the sensitivity of detection of the IS900 element in both conventional and real-time PCR assays. The specificity of the ISMap02 element was evaluated by PCR of the DNA extracted from isolates of M. avium subsp. paratuberculosis and M. avium subsp. avium, as well as DNA from M. fortuitum, M. scofulaceum, M. phlei, M. smegmatis, and M. gordonae. Only M. avium subsp. paratuberculosis DNA was detectable after amplification with the ISMap02 primers. The sensitivity of detection for the ISMap02 element in either a conventional or a real-time PCR format was less than 100 fg DNA or 10 super(2) CFU/ml in serial titration curves with pure bacteria. These results were comparable to those obtained for the IS900 element. Experimental spiking of a negative fecal sample followed by M. avium subsp. paratuberculosis DNA extraction resulted in detection thresholds of 10 super(2) CFU/g for the IS900 element and 10 super(3) CFU/g for the ISMap02 element by using a real-time PCR format, but this sensitivity dropped 10-fold for both elements in a conventional PCR format. Analyses of fecal samples obtained from naturally infected animals demonstrated a sensitivity for the detection of M. avium subsp. paratuberculosis DNA by use of the ISMap02 element similar to that achieved by use of the IS900 element when it was used in a conventional PCR format. The real-time PCR format improved the levels of detection of both elements, but not to a significant degree. In conclusion, the ISMap02 element provides a very sensitive and specific alternative as a diagnostic reagent for use in PCR assays for the detection of paratuberculosis.

Sulfur cinquefoil is an exotic perennial plant invading interior Pacific Northwest rangelands. Because sulfur cinquefoil produces distinctive pale yellow flowers, we timed aerial photography for early July, when the plant was at peak bloom. Photography was collected at 3 spatial scales (1:3 000, 1:6 000, and 1:12 000). A grid with 250-m spacing was superimposed over photographs of the entire study area using geographic information systems. At each grid intersection point (n = 80), we visually analyzed the photographs within a 404.7-m super(2) (0.1 acre) circular plot, recorded sulfur cinquefoil presence, and estimated sulfur cinquefoil percent cover. Sample points on the grid were then located in the field using a global positioning system. Field data collected at each point included sulfur cinquefoil presence, percent cover, and stem density; and total vegetation composition and percent cover by life form. Results indicate that the accuracy of detecting sulfur cinquefoil increased from small to large scale. At the 1:3 000 scale, sulfur cinquefoil presence was correctly identified in 76.9% of the sites, whereas at the 1:6 000 and 1:12 000 scales, infestations were identified in 67.9% and 59.1% of the sites, respectively. Low-density infestations (< 1% cover) were detected at all scales. Accuracy of percent cover estimates ranged from 33.8% to 38.0% across scales. Although tree canopy hindered detection, our results indicate that aerial photography can be used to detect sulfur cinquefoil infestations in open forests and rangelands in the Intermountain West.Original Abstract: Evaluamos la efectividad de la fotografia aerea de color natural como una herramienta para mejorar la deteccion, monitoreo y mapeo de las infestaciones del 'Sulfur cinquefoil' (Potentilla recta L.) la cual es una planta perenne exotica que esta invadiendo los pastizales interiores de la region noroeste del Pacifico. Debido a que el 'Sulfur cinquefoil' produce flores de color amarillo palido que es distintivo, programamos la fotografia para inicios de Julio, cuando la planta esta el maximo de floracion. La fotografia se colecto a tres escalas espaciales (1:3 000, 1:6 000, 1:12 000). Una cuadricula con espaciamiento de 250-m entre puntos se sobrepuso en las fotografias del area total de estudio usando sistemas de informacion geografica. En cada punto de interseccion de la cuadricula (n = 80), analizamos visualmente las fotografias dentro de una parcela circular de 0.1-acre, registrando la presencia de 'Sulfur cinquefoil' y estimamos el porcentaje de cobertura de esta especie. Los puntos de la muestra en la cuadricula fueron localizados en el campo usando un sistema de posicionamiento global. Los datos de campo colectados en cada punto incluyeron la presencia de 'Sulfur cinquefoil', el porcentaje de cobertura, la densidad de tallos, la composicion total de la vegetacion y el porcentaje de cobertura por forma de vida. Los resultados indican que la certeza de detectar el 'Sulfur cinquefoil' aumento de la escala pequena a la grande. En la escala de 1:3 000 la presencia de 'Sulfur cinquefoil' fue identificada correctamente en el 76.9% de los sitios, mientras que en las escalas de 1:6 000 y 1:12 000 las infestaciones fueron identificadas en 67.9% y 59.1% de los sitios, respectivamente. Las infestaciones de baja densidad (< 1% cobertura) fueron detectadas en todas las escalas. La certeza de las estimaciones del porcentaje de cobertura vario de 33.8%-38.0% a traves de todas las escalas. Aunque la copa de los arboles interfirieron la deteccion, nuestros resultados indican que la fotografia aerea puede ser usada para detectar las infestaciones de 'Sulfur cinquefoil' en bosques abiertos y pastizales del oeste intermontanoso.

Chainsaw cutting of western juniper woodlands is a commonly applied practice for removing tree interference and restoring understory composition. Studies reporting understory response following juniper cutting have been limited to early successional stages. This study assessed successional dynamics spanning 13 years following tree cutting. Total herbaceous standing crop and cover increased significantly in the CUT. Total standing crop was 10 times greater in the CUT vs. WOODLAND. Herbaceous standing crop and cover, and densities of perennial grasses in the CUT did not change between 1996 and 2004 indicating that by the 5th year after cutting, remaining open areas had been occupied. In the early successional stages, perennial bunchgrasses and Sandberg's bluegrass were dominant. By the 5th year after treatment, cheatgrass had supplanted Sandberg's bluegrass and was codominant with perennial bunchgrasses. In 2003 and 2004, perennial bunchgrasses dominated herbaceous productivity in the CUT, representing nearly 90% of total herbaceous standing crop. A pretreatment density of 2-3 perennial bunchgrasses m super(-2) appeared to be sufficient to permit natural recovery after juniper control. Perennial bunchgrass density peaked in the 6th year after treatment and the results suggested that 10-12 plants m super(-2) were sufficient to fully occupy the site and dominate herbaceous composition in subsequent years. In the CUT, juniper rapidly reestablished from seed and from the presence of seedlings not controlled in the initial treatment. The shifts in herbaceous composition across years suggests that long term monitoring is important for evaluating plant community response to juniper control and to develop appropriate post treatment management to promote continued site improvement.Original Abstract: La expansion del 'Western juniper' (Juniperus occidentalis spp. occidentalis Hook.) en las comunidades vegetales de las estepas de 'Sagebrush' de la Gran Cuenca del norte ha disminuido la productividad de esta estepa arbustiva y su diversidad. La tala de bosques de 'Western juniper' con sierra de cadena es una practica comunmente usada para remover la interferencia de los arboles y restaurar la composision del estrato vegetal inferior. Los estudios que reportan la respuesta del estrato vegetal inferior posterior al corte del 'Western juniper' han sido limitados a los primeros estados sucesionales. Este estudio aborda las dinamicas sucesionales medidas durante un periodo de 13 anos despues del corte de los arboles. La biomasa total y cobertura de herbaceas se incrementaron significativamente con el corte de los arboles. La biomasa total fue 10 veces mayor en las areas con corte de arboles (CUT) que en las areas intactas (WOODLAND). En el tratamiento con corte (CUT), la biomasa, cobertura y densidades de zacates perennes no cambiaron durante 1996 y 2004, indicando que para el quinto ano despues del corte las areas abiertas remanentes habian sido ocupadas. En las etaps tempranas de la sucesion, los zacates perennes amacollados y el 'Sandberg's bluegrass' (Poa sandbergii Vasey) fueron los dominantes. En quinto ano despues de aplicar el tratamiento, el 'Cheatgrass' habia suplantado al 'Sandberg's bluegrass' y fue la especie codominante con los zacates amacollados perennes. En 2003 y 2004, los zacates amacollados pernnes dominaron la productividad del estrato herbaceo en el tratamiento de corte (CUT), representando casi el 90% del total de la biomasa herbacea. Antes de aplicar el tratamiento, una densidad de zacates amacollados de 2 a 3 plantas m super(-2) parecieron ser suficientes para permitir la recuperacion natural despues del control del 'Western juniper.' El pico de la densidad de zacates amacollados fue en el sexto ano despues de aplicar el tratamiento de corte (CUT) y los resultados sugieren que 10-12 plantas m super(-2) fueron suficientes para ocupar totalmente el sitio y dominar la composicion herbacea en los anos subsecuentes. En el tratamiento de corte (CUT), el 'Western juniper' se reestablecio rapidamente a partir de semilla y de la presencia de plantulas no controladas en el tratamiento inicial. Las cambios en la composicion herbacea a traves de los anos sugieren que un monitoreo a largo plazo es importante para evaluar la repuesta de la comunidad vegetal al control del 'Western juniper' y desarrollar un manejo apropiado post tratamiento para promover la mejoria continua del sitio.

The instrument most commonly used to do point sampling is the point frame. Since its introduction, the point frame has undergone numerous modifications to improve efficiency and ease of use. This article introduces a laser point frame (LPF) that was designed by the Agricultural Research Service for measurement of ground cover and utilizes lasers in place of conventional metal pins. A comparative pilot study was conducted on a shortgrass prairie in northern Colorado to compare data collected using a magnetic point frame (MPF) with data collected using the LPF. Cover by species was measured from identical plots using 100 points per plot for each point frame, and sampling times were recorded for each plot. Correlations between cover data collected using the MPF and the LPF were relatively high (r super(2) = 0.62-0.81). Total average vegetative cover measured with the MPF was 35%, compared with 40%, using the LPF. Cover of total grasses, C sub(4) grasses, C sub(3) grasses, and litter, were significantly greater with the LPF method. Total sampling time per 100 points was almost half using the LPF compared with the MPF. The LPF was easy to use, efficient for measurement of cover, and is a potential replacement for conventional point frames.Original Abstract: Desde que fue introducido por Levy en 1927, el muestreo de puntos ha sido un metodo sin parcela estandar para la medicion de la cobertura del suelo en pastizales. El instrumento mas comunmente utilizado para colectar las muestras es el marco de puntos, el que desde su introduccion ha sufrido varias modificaciones para mejorar su eficiencia y facilitar su uso. Este articulo introduce un marco de puntos laser (LPF) que fue disenado por el Servicio de Investigacion Agricola para medir la cobertura del suelo y utiliza rayos laser en lugar las aguas metalicas convencionales. Un estudio piloto comparativo se condujo en un pastizal de zacates cortos del norte de Colorado para comparar los datos colectados usando un marco de puntos magnetico (MPF) con los datos colectados usando el LPF. La cobertura por especies fue medida en parcelas identicas usando 100 puntos por parcela para cada marco de puntos y los tiempos de muestreo se registraron para cada parcela. Las correlaciones entre los datos de cobertura colectados usando el MPF y LPF fueron relativamente altas (r super(2) = 0.67-0.81). La cobertura vegetativa total promedio medida con el MPF fue 35% comparada con 40% usando el LPF. La cobertura total de zacates C sub(4), zacates C sub(3) y mantillo fueron significativamente mayores con el metodo de LPF. El tiempo total de muestreo por cada 100 puntos con el LPF fue casi la mitad del necesitado con el MPF. El LPF fue facil de usar, fue eficiente para las mediciones de cobertura y es un reemplazo potencial de los marcos de puntos convencionales.

Importantly, the DCH test allows one to determine that a data set is error-free. dropout has been evaluated in McKelvey & Schwartz (2004) and is now available online.

The objective of this study was to compare the effects of light and moderate stocking rates on weight gains of heifers grazing twice-replicated 16-ha pastures in late fall (November to mid-January) from 1996 to 1998, and in early spring (April to mid-May) from 1996 to 1999. Stocking rates for late fall (light: 1.3-1.5 ha . animal unit month super(-1) [AUM super(-1)] vs. moderate: 0.8-1.0 ha . AUM super(-1)) and early spring (light: 3.7-4.0 ha . AUM super(-1) vs. moderate: 2.3-2.5 ha . AUM super(-1)) were achieved using 5 (for light grazing) and 8 (for moderate grazing) Hereford heifers, with initial average weights of 405 plus or minus 5.7 (mean plus or minus 1 SE) kg for the late fall grazing period and 267 plus or minus 3.8 kg for the early spring grazing period across the study years. Average daily gain was 58% greater for light (0.65 plus or minus 0.06 kg . head super(-1) . d super(-1)) compared to moderate (0.41 plus or minus 0.05 kg . head super(-1) . d super(-1)) stocking rates in the late fall grazing period, and 115% greater with light (0.59 plus or minus 0.06 kg . head super(-1) . d super(-1)) than with moderate (0.27 plus or minus 0.07 kg . head super(-1) . d super(-1)) stocking rates in the early spring grazing period. Beef production did not differ between stocking rates for either the late fall (16.4 plus or minus 3.9 vs. 17.4 plus or minus 4.5 kg gain . ha super(-1), light vs. moderate stocking rates) or early spring (9.6 plus or minus 2.7 vs. 7.6 plus or minus 4.8 kg gain . ha super(-1)) grazing periods. We suggest that land managers employ light stocking rates during both grazing periods to obtain adequate individual animal gains without sacrificing gains per unit land area. Lengthening the grazing season in the shortgrass steppe should be economically desirable to land managers because feed costs could be lowered and animal gains obtained through minimal input.Original Abstract: La eficiencia de la produccion del ganado en los pastizales de zacates cortos puede ser incrementada con el apacentamiento de pastizales dominados por 'Fourwing saltbush' (Atriplex canescens [Pursh] Nutt) a fines de otono y/o inicios de primavera, pero hay una escasez de informacion concerniente a las cargas animal y ganancias del animal. El objetivo de este estudio fue comparar los efectos de cargas animal ligeras y moderadas en las ganancias de peso de vaquillas apacentando a fines de otono (Noviembre a mediados de Enero) potreros de 16 ha repetidos dos veces, durante el periodo de 1996 a 1998 y a inicios de primavera (Abril a mediados de Mayo) de 1996 a 1999. Las cargas animal (ha UAM super(-1)) para fines de otono (ligero: 1.3-1.5 vs. moderado: 0.8-1.0) e inicios de primavera (ligero: 3.7-4.0 vs. moderado: 2.3-2.5 ha UAM super(-1)) fueron logradas usando 5 (ligero) y 8 (moderado) vaquillas herford, con pesos iniciales promedio de 405 plus or minus 5.7 kg para el periodo de apacentamiento de fines de otono y 267 plus or minus 3.8 kg para los periodos de apacentamiento a inicios de primavera a traves de los anos de estudio. La ganancia diaria promedio fue 58% mayor para la carga ligera (0.65 plus or minus 0.06 kg hd super(-1) d super(-1), media plus or minus 1EE) en comparacion con la carga moderada (0.41 plus or minus 0.05 kg hd super(-1) d super(-1)), esto para las cargas del periodo de fines de otono y 115% mayor con la carga ligera (0.59 plus or minus 0.06 kg . hd super(-1) . d super(-1)) que con la moderada (0.27 plus or minus 0.07 kg . hd super(-1) . d super(-1)) en el periodo de inicios de primavera. La produccion de carne no difirio entre cargas animal, tanto en los periodos de apacentamiento de fines de otono, (16.4 plus or minus 3.9 vs. 17.4 plus or minus 4.5 kg ganacia ha super(-1), carga ligera vs. moderada) como los de inicios de primavera (9.6 plus or minus 2.7 vs. 7.6 plus or minus 4.8 kg gain . ha super(-1)). Sugerimos que los manejadores de pastizales empleen cargas ligeras en ambos periodos de apacentamiento para obtener ganancias animal individuales adecuadas sin sacrificar las ganancias por unidad de area. Alargar la estacion de apacentamiento en los pastizales de zacates cortos debe ser economicamente deseable para los manejadores del pastizal conforme los costos de alimentacion pudieran ser bajados y las ganancias animal sean obtenidas con entradas minimas.

These factors operate at different spatial scales and may affect the number and relative abundances of species differently. We measured diversity of plant species and functional groups of species in replicated plots within paired restored and remnant (relic) tallgrass prairies at three locations in central Texas, U.S.A. To determine the contributions of species abundances and of spatial patterns of diversity to differences between prairie types, we separated diversity into richness and evenness (relative biomass) and into within-plot ( alpha ), among-plot ( beta ), and prairie ( gamma ) components. Species diversity was greater in remnant than in restored prairies at all spatial scales. At the gamma scale, both species richness and species evenness were greater in remnants because of greater spatial variation in species composition. At the alpha scale, remnants were more diverse because of greater richness alone. Mean alpha richness correlated positively with the size of the species pool in restored prairies only, implying that in remnants, alpha richness was influenced more by colonization dynamics than by the number of species available for colonization. Plots in remnant prairies contained more functional groups and fewer species per group than did plots in restored prairies, suggesting that resource partitioning was greater in relic prairies. Our results are consistent with the interpretation that local ecological processes, like resource partitioning and limitations on seed dispersal, contribute to the greater diversity of remnant than restored prairies in central Texas. Restoration practices that limit abundances of competitive dominants, increase the number of species in seed mixtures, and increase the proximity of plants of different functional groups thus may be required to better simulate the plant diversity of tallgrass prairies.

One study area (mesic) was dominated by mixed-conifer forest, the other (xeric) by ponderosa pine (Pinus ponderosa) forest and pinon (P. edulis)-juniper (Juniperus) woodland. Based on existing knowledge of relative use of forest types by Mexican spotted owls, we predicted that the mesic area would provide habitat of higher quality for spotted owls. Results generally supported this prediction. Median home-range size for owls in the mesic area was approximately half that of owls in the xeric area during both the breeding and non-breeding seasons (n = 6 owls in each area). Despite their reduced size, however, mesic-area home ranges contained twice as much mixed-conifer forest as xeric-area ranges. Owls roosted primarily (>80% of roosting locations in both seasons) in mixed-conifer forest in both study areas, and home-range size was inversely related to relative amount of mixed-conifer forest within the home range during both seasons. Both survival and fecundity rates were higher in the mesic than in the xeric area. Estimates of population trend based on observed vital rates suggested that the population in the mesic area was self-sustaining or nearly so during the period of study (1992 through 1994), but the population in the xeric area was not. Collectively, our findings suggest that habitat quality for spotted owls was higher in the mesic area than in the xeric area, and that the xeric area might function as an ecological sink. These results support the need for data linking demographic performance to habitat conditions in development of strategies for recovering threatened and endangered species.Original Abstract: Estudiamos el rango de hogar, uso de habitat, y las tasas vitales de los tecolotes manchados mexicanos (Strix occidentalis lucida) en 2 areas de estudio en las Sacramento Mountains de New Mexico, USA. Un area de estudio (mesica) estuvo dominada por bosques de coniferas mixtas, la otra (xerica) por bosques de pino ponderosa (Pinus ponderosa) y bosques lenosos de pino pinonera (P. edulis) y enebros (Juniperus). Basados en el conocimiento existente del uso relativo de tipos de bosques por el tecolote manchado mexicano, predecimos que el area mesica proveeria un habitat de la mas alta calidad para los tecolotes. Los resultados en general respaldan esta prediccion. El tamano medio del rango de hogar para los tecolotes en el area mesica fue aproximadamente la mitad de el de los tecolotes en el area xerica durante y fuera de la temporada de reproduccion (n = 6 tecolotes en cada area). A pesar de sus tamanos reducidos, sin embargo, los rangos de hogar mesicos contuvieron el doble de bosques de coniferas mixtas que los rangos de hogar xericos. Los tecolotes pasaron la noche (>80% de los lugares de descanso en ambas temporadas) principalmente en bosques de coniferas mixtas en ambas areas de estudio, y el tamano del rango de hogar estuvo inversamente relacionado a la cantidad relativa de bosques de coniferas mixtas dentro del rango de hogar durante ambas temporadas. Las tasas de supervivencia y fecundidad fueron mas altas en el area mesica que en la xerica. Estimaciones de las tendencias poblacionales basadas en observaciones de tasas vitales sugieren que la poblacion en el area mesica se sostuvo sola o casi se sostuvo durante el periodo de estudio (1992 a 1994), pero la poblacion en el area xerica no. Colectivamente, nuestros hallazgos sugieren que la calidad del habitat para los tecolotes manchados fue mas alta en el area mesica que en la xerica, y que el area xerica puede operar como un sumidero ecologico. Estos resultados respaldan la necesidad de considerar juntos los datos de rendimiento demografic y los de condiciones de habitat en desarrollar estrategias para la recuperacion de especies amenazadas y en peligro de extincion.

In the laboratory, nymphs were reared until adult emergence. Four (Bryocorinae, Deraeocorinae, Mirinae, and Orthotylinae) of the eight mirid subfamilies were collected during the study. Twenty-two mirid species on 43 putative host plant species were collected in Argentina, and five species of mirids on eight plant species were collected in Paraguay. Eighty-five new mirid-plant associations were recorded (only 112 mirid-plant associations had been reported previously for Argentina). Most of the mirids were in the subfamily Mirinae, tribe Mirini, and most of the host plants belonged to Asteraceae. Almost all mirids were collected on plants with flower buds present. In addition to host plant records, the phenology and pattern of plant use for the most abundant mirids are reported. Mirid richness and abundance varied according to the host plant species; the highest diversity and richness of mirids occurred in the western region of Argentina (Salta, Jujuy, and Tucuman provinces). The most frequently collected mirid, Taylorilygus apicalis (Fieber) ( approximately 87% of the 35,970 collected mirids), was usually collected on Asteraceae. This exotic species could have affected the native mirid fauna in the study area. More research on the possible interactions between T. apicalis and the native mirids of Argentina and Paraguay is needed. Our results suggest that T. apicalis exhibits regional polyphagy, i.e., uses numerous hosts throughout its geographic range.Original Abstract: Entre Noviembre de 1999 y Septiembre de 2001, ninfas de miridos (Hemiptera: Miridae) fueron colectadas sobre plantas silvestres y cultivadas en centro y norte de Argentina y el sudeste de Paraguay. Las ninfas colectadas se criaron hasta el estado adulto en el laboratorio. De las eight subfamilias de miridos conocidas, se colectaron four en este estudio: (Bryocorinae, Deraeocorinae, Mirinae, y Orthotylinae). En Argentina, 22 especies de miridos fueron colectadas sobre 43 especies de plantas, y 5 miridos sobre ocho plantas en Paraguay. Un total de 85 asociaciones planta-insecto nuevas fueron registradas (112 eran conocidas previamente en Argentina). La mayoria de los miridos colectados pertenecian a la subfamilia Mirinae, tribu Mirini, mientras que las plantas hospedadoras pertenecieron a la familia Asteraceae. La casi totalidad de los miridos fueron colectados sobre plantas con flores presente. Ademas de los datos sobre las plantas hospedadoras de los miridos, se presentan datos sobre fenologia y patrones de utilizacion de las plantas de los miridos mas abundantes. En general la riqueza y la abundancia de los miridos vario de acuerdo a las especies de las plantas hospedadoras; la mayor diversidad y riqueza de miridos se observo en el oeste de Argentina (en las provincias de Salta, Jujuy, Tucuman). Taylorilygus apicalis (Fieber) fue el mirido mas abundante (87% de los 35.970 miridos colectados) y en la mayoria de los casos sobre Asteraceae. Esta especie exotica podria estar afectando la fauna nativa de miridos en el area estudiada. Sin embargo, se necesita de mas investigacion para establecer las posibles interacciones entre la fauna de miridos de Argentina y Paraguay y T. apicalis. Nuestros resultados sugieren que T. apicalis muestra una polifagia regional, por ejemplo, utiliza numerosas plantas hospedadoras a lo largo de su distribucion geografica.

Key life history characteristics of flies on or from the new hosts also were examined. Rearing of larvae to adults confirmed native cascara, Rhamnus purshiana DC.; black hawthorn, Crataegus douglasii Lindl.; and introduced cherry laurel, Prunus laurocerasus L., are suitable developmental hosts. In addition, two flies reared from cascara had wing patterns apparently not reported previously, with one keying out to R. indifferens. The numbers of larvae that emerged from fruit of the new hosts and a known host, bitter cherry, Prunus emarginata (Dougl. ex. Hook) D. Dietr., were lower than from fruit of sweet and sour cherries, Prunus avium (L.) L. and Prunus cerasus L. Seasonal patterns of adult abundance in cascara, black hawthorn, and cherry laurel as determined by catches on unbaited sticky yellow panel traps were similar to those in bitter cherry, with most flies caught beginning in mid-July after fruit were no longer green. Fruit of all hosts ripened at similar times. On cascara and black hawthorn, R. indifferens was observed feeding on damaged fruit, and on black hawthorn, flies mated with the non-native apple maggot, Rhagoletis pomonella (Walsh). The longevity of flies reared from cascara, bitter cherry, and sweet and sour cherry was similar, averaging 55.5-83.4 d, and was higher than that of flies reared from cherry laurel, which averaged less than or equal to 46.2 d. Body mass of flies from cascara, cherry laurel, and bitter cherry was lower than that of flies from sweet cherry. In contrast to the coast forest ecosystem, neither cascara nor cherry laurel was found at sites studied in ponderosa pine and sagebrush-bunchgrass ecosystems in central Washington in 2003 and 2004. Adults were not caught on unbaited traps in black hawthorns in these two ecosystems, and no larvae were reared from hawthorn fruit from either ecosystem.

Methods and Results:Aliquots of rinsates, incubated in BBL Enterococcosel broth at 37 degree C, 42 degree C, or 45 degree C for 24 and 48 h, were inoculated onto BBL Enterococcosel and M-enterococcus agar. Presumptive positive colonies were identified to species and tested for antibiotic resistance. Significant differences (P less than or equal to 0.05) were observed for media and temperature. More Enterococcus faecalis were isolated from M-enterococcus media and at 37 degree C while more E. faecium were isolated from Enterococcosel agar and at 45 degree C. The number of antibiotic-resistant E. faecalis and E. faecium were also affected by media and temperature. Conclusions:Culture conditions for enterococci affect the observed species and antibiotic resistance patterns and therefore should be carefully considered. Significance and Impact of the Study:This study indicates that media and temperature can influence the recovery and selection of enterococcal species and antibiotic susceptibility.

Inactivation experiments were conducted with feline calicivirus (FCV), closely related to the human caliciviruses based on nucleic acid organization and capsid architecture, and adenovirus type 40 (AD40). Experiments were carried out in buffered disinfectant demand free water at pH 7 and 5 degree C. Ct values; concentration of ozone multiplied by contact time with virus; were determined from application of the efficiency factor hom (EFH) model. Ct values for 4-log (99.99%) ozone inactivation at 5 degree C and pH 7 ranged from 0.07 to 0.60 mg/l min for AD40 and - 0.01 to 0.03 mg/l min for FCV. Ct values listed in the US environmental protection agency "Guidance Manual for Compliance with Filtration and Disinfection Requirements for Public Water Systems Using Surface Water Sources" were higher than Ct values generated by this study. Very low ozone residuals (-0.01(mg/l) substantially inactivated FCV and AD40 under the studied conditions.

In addition, some of the cell lines that were refractive to AcMNPV were tested with AcMNPV hsp70 Red, a recombinant carrying the red fluorescent protein (RFP) gene, for their ability to express this protein after inoculation. Of the 10 lepidopteran cell lines tested, only three cell lines from Helicoverpa zea (BCIRL-HZ-AM1), Lymantria dispar (IPLB-LD 65), and Cydia pomonella (CP-169) failed to support detectable viral replication as measured by tissue culture infectious dose 50 (TCID sub(50)) assay. Heliothis virescens (BCIRL-HV-AM1) produced the highest viral titer of 2.3 plus or minus 0.1 x 10 super(7) TCID sub(50)/ml followed by Heliothis subflexa (BCIRL-HS-AM1) at 4.7 plus or minus 0.1 x 10 super(6) TCID sub(50)/ml and Spodoptera frugiperda (IPLB-SF21) at 4.1 plus or minus 0.1 x 10 super(6) TCID sub(50)/ml. None of the coleopteran, dipteran, or homopteran cell lines supported AcMNPV replication. However, when studies were performed using AcMNPV hsp70 Red, the dipteran cell lines Aedes aegypti (ATC-10) and Drosophila melanogaster (line 2), both expressed the RFP as well as the refractive lepidopteran cell lines from H. zea and L. dispar. No RFP expression was observed in any of the coleopteran or homopteran cell lines. Cell lines refractive to AcMNPV did not appear to be adversely affected by the virus, as judged by their ability to multiply, nor was there any indication of induced apoptosis, as assessed by deoxyribonucleic acid fragmentation profiles or cell blebbing, or both.

Therefore, ergovaline movement across human intestinal cells was assessed using Caco-2 cells derived from human colon carcinoma. A pre-equilibrated mixture of ergovaline/ergovalinine (60:40 ratio of isomers) was added to the apical compartment, and isomer movements were assessed by high-performance liquid chromatography (HPLC) of extracted media (initial pre-isomerized ergovaline concentrations of 6 and 22 mu M, two doses). Mathematical models for ergot alkaloid movement were developed. Rates of movement were not different for the isomers. In the absence of cells, basal accumulation of isomers was essentially linear for 3 h regardless of loading concentration, after which basal accumulation of ergovaline/ergovalinine plateaued. Rates of ergovaline/ergovalinine movement in the presence of cells slowed to about 25% the rate of movement in the absence of cells (22 mu M, kt = 0.0133 no cells, 0.0036 with cells, P < 0.05). Mass transfer rate was 7.5 ng.cm super(-2).min super(-1) and was similar to that reported for ergovaline using a parabiotic chamber with sheep omasum. After 6 h in the presence of cells, similar to 25 and 40% of the total ergovaline/ergovalinine administered had accumulated in the basal compartment for 6.6 and 22 mu M treatments, respectively. Ergovaline and its naturally occurring isomer, ergovalinine, readily crossed intestinal cells intact and at similar rates. Either isomer, or a combination of both, could be involved in the pathogenesis of fescue toxicosis at sites distal to the intestine.

Surprisingly, genetic studies of Arthropods and particularly the insects have not benefited yet from the contributions that non- invasive methods have made. Here, we outline a strategy for identifying phytophagous insect genetic entities based on direct-PCR of fecal DNA combined with double strand conformation polymorphism (DSCP) typing. This allows the differentiation of morphocryptic entities within the species Ceutorhynchus assimilis (Coleoptera: Curculionidae), a candidate biocontrol agent of a noxious weed. The results obtained clearly demonstrate the potential for this method to provide a valuable means for genetic and ecological studies of Arthropods.

We conducted a grazing study to determine if forage species diversity in pastures affects herbage productivity and weed invasion. One-hectare pastures were planted to four mixtures in August 2001 and then grazed with lactating dairy cattle during 2002 and 2003. The mixtures were two species [orchardgrass (Dactylis glomerata L.) and white clover (Trifolium repens L.)], three species [orchardgrass, white clover, and chicory (Cichorium intybus L.)], six species [orchardgrass, tall fescue (Festuca arundinacea Schreb.), perennial ryegrass (Lolium perenne L.), red clover (Trifolium pratense L.), birdsfoot trefoil (Lotus corniculatus L.), and chicory], and nine species [the six-species mixture plus white clover, alfalfa (Medicago sativa L.), and bluegrass (Poa pratensis L.)]. When rainfall was plentiful (2003), there were no differences in herbage yield among the mixtures; all averaged 9800 kg ha super(-1) dry matter. During 2002, which was dry, the two-species mixture produced less herbage than the other mixtures (4800 vs. 7600 kg ha super(-1) dry matter). The proportion of nonsown species in the sward was lower for the six- and nine-species mixtures than the two-and three-species mixtures, indicating less weed invasion for these complex mixtures. Red clover and chicory proportions decreased by 80% after 2 yr, and orchardgrass dominated in all pastures by May 2004. We conclude that planting a mixture of grasses, legumes, and chicory will benefit herbage production during dry years and will reduce weed invasion for a few years after planting under management similar to ours. Producers would have to reestablish the chicory and legume components relatively frequently to maintain these benefits.

Deleting phzR and phzI from strain 2-79 led to loss of production of the antibiotics, as well as a suite of six acyl-homoserine lactones (acyl-HSLs) that includes four 3-hydroxy- derivatives and two alkanoyl-HSLs. Strain 2-79 accumulates N-(3-hydroxy-hexanoyl)-L-HSL to levels 20 and 30 times those of N-(hexanoyl)-L-HSL and N-(3-hydroxy-octanoyl)-HSL, the next most abundant species produced by this isolate. Expression of a clone of phzI in Escherichia coli and P. fluorescens 1855 resulted in the synthesis of all six acyl-HSLs. Maximal activation of phzA and phzR fused to lacZ and uidA reporters, respectively, required PhzR and the acyl-HSL signals. PhzR-mediated expression of the phzA::lacZ fusion responded with highest sensitivity and greatest magnitude to pure N-(3-hydroxy-hexanoyl)-L-HSL. When exposed to organic extracts of culture supernatants containing the six acyl-HSLs at their normal levels, the reporter responded strongly to N-(3-hydroxy-hexanoyl)-L-HSL but did not respond to any of the other five acyl-HSLs. The transcriptional start sites for the divergently oriented phzA and phzR genes were mapped by primer extension analysis. An 18-bp almost perfect inverted repeat, the phz box, is located between the phzI and phzR promoters. Disrupting this repeat abolished PhzR-dependent activation of phzA and phzR. We conclude that PhzI of strain 2-79 synthesizes 3-OH acyl-HSLs and that P. fluorescens 2-79 uses N-(3-hydroxy-hexanoyl)-HSL as its quorum-sensing signal. We also conclude that PhzR, with its quormone, activates expression of phzA and phzR and that this activation requires an intact phz box sequence located in the divergent promoter region.

Hydrogen peroxide is generated as an intermediary analyte, which allows flexibility in the choice of the chromophore or fluorophore used as the final reporter. Thus, we present D-xylose quantitation results for solution-phase assays performed with both the fluorescent reporter resorufin, generated from N-acetyl-3,7-dihydroxyphenoxazine (Amplex Red), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), whose corresponding radical cation has an absorbance maximum at similar to 400 nm. We also describe a useful solid-phase variation of the assay performed with the peroxidase substrate 3,3'-diaminobenzidine tetrahydrochloride, which produces an insoluble brown precipitate. In addition, kinetic parameters for hydrolysis of the natural substrates xylobiose and xylotriose were obtained using this assay for a glycosyl hydrolase family 39 beta -xylosidase from Thermoanaerobacterium sp. strain JW/SL YS485 (Swiss-Prot accession no. O30360). At higher xylobiose substrate concentrations the enzyme showed an increase in the rate indicative of transglycosylation, while for xylotriose marked substrate inhibition was observed. At lower xylobiose concentrations k sub(cat) was 2.7 plus or minus 0.4 s super(-1), K sub(m) was 3.3 plus or minus 0.7 mM, and k sub(cat)/K sub(m) was 0.82 plus or minus 0.21 mM super(-1) . s super(-1). Nonlinear curve fitting to a substrate inhibition model showed that for xylotriose K sub(i) was 1.7 plus or minus 0.1 mM, k sub(cat) was 2.0 plus or minus 0.1 s super(-1), K sub(m) was 0.144 plus or minus 0.011 mM, and k sub(cat)/K sub(m) was 14 plus or minus 1.3 mM super(-1) . s super(-1).

Our objectives were to characterize (i) nitrate N movement from waste application fields (WAFs) in shallow ground water, and (ii) soil, hydrologic, and biological factors influencing the amount of nitrate N in the adjacent stream. A ground water monitoring study was conducted for 36 mo on a swine farm managed under new regulations. Water table contours and lack of vertical gradients indicated horizontal flow over most of the site. Nitrate N concentrations in water from shallow wells in WAFs averaged 30 plus or minus 19 mg L super(-1) and [delta] super(15)N ratios for nitrate N were between +20 and +25 per mil. Nitrate N concentration decreased from field-edge to streamside wells by 22 to 99%. Measurement of [delta] super(18)O and [delta] super(15)N enrichment of nitrate in ground water throughout the WAF-riparian system indicated that denitrification has not caused significant super(15)N enrichment of nitrate. Over a 24-mo period, [delta] super(15)N ratios for nitrate N in the stream approached [delta] super(15)N ratios for nitrate N in ground water beneath WAFs indicating delivery of some waste-derived nitrate N to the stream in shallow ground water. Nitrate N concentrations in the stream were relatively low, averaging 1 mg L super(-1). Dilution of high nitrate N water in shallow horizontal flow paths with low nitrate N water from deeper horizontal flow paths at or near the stream, some denitrification as ground water discharges through the stream bottom, and some denitrification in riparian zone contributed to this low nitrate N concentration.

Reductions in water dissolved P concentrations through very strong P sorption reactions may be obtainable after land application of alum-based drinking water treatment residuals (WTRs). Our objectives were to (i) evaluate the ability of an alum-based WTR to reduce Mehlich-3 phosphorus (M3P) and water-soluble phosphorus (WSP) concentrations in three P-enriched Coastal Plain soils, (ii) estimate WTR application rates necessary to lower soil M3P levels to a target 150 mg kg super(-1) soil M3P concentration threshold level, and (iii) determine the effects on soil pH and electrical conductivity (EC). Three soils containing elevated M3P (145-371 mg kg super(-1)) and WSP (12.3-23.5 mg kg super(-1)) concentrations were laboratory incubated with between 0 and 6% WTR (w w super(-1)) for 84 d. Incorporation of WTR into the three soils caused a near linear and significant reduction in soil M3P and WSP concentrations. In two soils, 6% WTR application caused a soil M3P concentration decrease to below the soil P threshold level. An additional incubation on the third soil using higher WTR to soil treatments (10-15%) was required to reduce the mean soil M3P concentration to 178 mg kg super(-1). After incubation, most treatments had less than a half pH unit decline and a slight increase in soil EC values suggesting a minimal impact on soil quality properties. The results showed that WTR incorporation into soils with high P concentrations caused larger relative reductions in extractable WSP than M3P concentrations.

We investigated the relative contributions of primary and secondary seed dispersal of Sierra bush chinquapin (Castanopsis sempervirens; Fagaceae) to seedling establishment. Rodents (mostly yellow pine chipmunks, Tamias amoenus) harvested chinquapin nuts rapidly during a three-week period starting in mid-August and scatterhoarded most nuts (81%) in the ground. Most initial (primary) caches contained one nut (range = 1-5 nuts) buried 10-23 mm deep within 46 m of source shrubs. Rodents subsequently retrieved 95% of these nuts and reached at least 33% elsewhere (secondary caches), at lower densities and up to 64 m from source plants. By winter, 41% and 21% of nuts harvested from shrubs remained in scatter caches in 1999 and 2000, respectively. Only 10 caches (4 primary and 6 secondary caches) present in winter 1999 (7.8%), and no caches from winter 2000, produced seedlings the following spring. All seedlings died during the first growing season because of rodent grazing and desiccation. Despite low seedling survival in this study, chinquapin appears to be dependent upon scatterhoarding rodents for seedling recruitment. Secondary dispersal is an important aspect of chinquapin dispersal. Secondary caches contributed more to chinquapin seedling recruitment than primary caches; 2.5% of primary caches and 5.6% of secondary caches produced seedlings. This study suggests that, for propagules that move repeatedly during dispersal, a clear understanding of the dynamics of seed dispersal can be gained only by following seed movements, determining the transition probabilities between different stages of dispersal, and assessing the contribution of each stage of seed dispersal to plant recruitment.

Identification of the immature stages is especially problematic, because distinguishing morphological features are difficult to use or have not been described. We used polymerase chain reaction (PCR) to distinguish closely related carabids and spiders, and to match eggs and larvae (or nymphs) with identified adult parents. Within the Carabidae, we amplified species-specific mitochondrial cytochrome oxidase I (COI) fragments for three species each in the genera Poecilus and Harpalus, and two each in Chlaenius and Bembidion. Within the Araneae, we amplified species-specific COI fragments for two Hibana species (Anyphaenidae), Pardosa milvina and Rabidosa rabida (Lycosidae), Frontinella communis and Grammonota texana (Linyphiidae), and Cheiracanthium inclusum (Miturgidae). We are able to correctly identify all immature stages tested - eggs, larvae (or nymphs) and pupae - by comparison of the amplified fragments with those of the adults. Using COI markers as species identifiers is a tenet of the Barcode of Life initiative, an international consortium to provide a molecular identifier for every animal species.

This study examined survivor analysis for evaluating a regional forest health issue - Missouri oak decline. With a statewide Missouri forest inventory, log-rank tests of the effects of covariates on the survivor function and equality of the survivor function among classes were conducted for selected oak species.Additionally, hazard functions were determined for diameter classes for damaged and undamaged oaks. Results indicate that mortality appears to vary significantly among some inventory classes such as oak species, but not among other classes such as ownership class. Indicators of individual tree vigor (i.e., crown class and ratio) were more significant predictors of oak tree mortality than site/stand attributes (i.e., density and aspect). Finally, results indicate that even fast-growing oak trees are at high risk of mortality if damaged by disease. Survival analyses, such as those applied in this study, may enable testing of forest health hypotheses using large-scale inventories. In the context of Missouri's oak forest decline, study results suggest management efforts should focus on limiting the spread of disease damage, increasing the vigor of residual trees, and emphasizing small trees when developing stand prescriptions.

Thermophilin 110 was isolated from culture supernatant after 16 h of growth and partially purified by a chloroform extraction procedure. The bacteriocin inhibited the growth of several lactic acid bacteria and in the case of Pediococcus acidilactici, it induced cell lysis with the concomitant release of OD sub(260) - absorbing material and intracellular enzymes. SDS-PAGE analysis revealed two components with estimated sizes between 4.0 kDa and 4.5 kDa, respectively, with possible involvement in bacteriocin activity as indicated by agar overlay assays with P. acidilactici as the target organism. Thermophilin 110 was inactivated by several proteolytic enzymes and also by alpha -amylase, which indicated the putative requirement of a glycosidic component for activity. The bacteriocin produced by S. thermophilus may be especially useful in the food processing industries to control spoilage caused by pediococci.

However, this BCMNV strain (designated NL-3 K) caused earlier and more severe symptoms on bean plants representing host groups 0, 4, and 5. The nucleotide sequence encoding the predicted polyprotein of NL-3 K was 9,893 nucleotides (nt) in length, yielding a peptide with a molecular size of 362.1 kDa compared with a 9,626-nt, 350.9-kDa polyprotein for NL-3 D. Sequence analysis of the putative P1 protein suggests that the NL-3 K strain is a recombinant between NL-3 D and the Russian strain (RU1) of Bean common mosaic virus. The P1 protein of NL-3 K consisted of 415 amino acids compared with 317 for NL-3 D. The first 114 predicted amino acids of the NL-3 K P1 region were 98% identical with RU1. The remaining 301 amino acids of the protein shared only 34% identity with RU1 but were 98% identical with NL-3 D. Primers were designed that flanked the recombination point in the P1 coding sequence of NL-3 K. An amplicon of the expected size was produced by reverse-transcriptase polymerase chain reaction of total nucleic acid extracts of bean plants inoculated with NL-3 K, but not from those with NL-3 D or RU1. The increased symptom severity on selected common bean lines induced by NL-3 K suggests that the P1 gene may play a significant role in pathogenicity and virulence.

Nine commercial maize hybrids, varying in reaction to PLS, were planted in a split-plot design with hybrids as whole plots and inoculated versus uninoculated treatments as subplots. The most susceptible hybrid, Pioneer brand 3489, sustained a significant reduction in grain yield (11 to 13%) and 400-kernel weight (5 to 10%) in the trials. Regression analyses indicated that grain yields and 400-kernel weights were reduced 0.23 and 0.16%, respectively, for each percent increase in PLS severity at the mid-dent stage. Because most U.S. maize hybrids are resistant, and PLS develops late in the grain-filling period, its potential to cause substantial losses in the United States appears limited at this time.

In spite of this long time scale, selection on life history attributes that affect seedling recruitment should be strong. We studied factors affecting germination phenology and seedling establishment for Coleogyne ramosissima, a dominant shrub species in the ecotone between warm and cold deserts in western North America. We also examined ecotypic differentiation in establishment strategy in response to selection regimes in two contrasting habitats. We followed patterns of dormancy loss, germination, emergence, and survival in reciprocal field experiments at warm winter Mojave Desert and cold winter Colorado Plateau study sites. Seed germination took place in late winter, under winter rain conditions at the warm desert site and under snow at the cold desert site. Distinctive germination phenologies for the two seed populations at contrasting field sites followed predictions based on laboratory germination experiments. There was no seed bank carryover across years. Seedling survival at the end of three growing seasons was remarkably high (mean survival 54%). Most seedling mortality was due to sprout predation by rodents early the first spring in unprotected caches. Emergence and establishment at each site were significantly higher for seeds from the local population, supporting the idea of ecotypic differentiation in establishment strategy. Establishment success was an order of magnitude greater overall at the Colorado Plateau site, which represents the leading edge of an upward elevational shift in distribution for this species under the current climatic regime. The Mojave Desert site is on the trailing edge of this shift, and recruitment there is apparently a much less frequent occurrence.

Because the arsenic component of CCA controlled copper-tolerant fungi, scientists have renewed interest in and concern about the decay capacity in the important copper-tolerant group of brown-rot fungi. We have demonstrated that the primary means of inactivating copper in preservatives is by excess production of oxalic acid (OA). Oxalic acid production is a key metabolic indicator of brown-rot decay, and our objective was to estimate the production of OA in five commercial or experimental arsenic- free preservatives. ten aggressive brown-rot fungi, chosen from previous studies and representing the genera Antrodia, Coniophora, Gloeophyllum, Postia, Serpula, Tyromyces, and Wolfiporia, were tested against southern yellow pine (SYP) blocks that were vacuum-treated with ground contact retentions of copper naphthenate, amine copper azole, alkaline copper quat type D (ACQ-D), N,N-naphthaloylhydroxylamine (NHA), and copper borate in a 12-week soil- block test. After determination of block weight loss, blocks were also tested for the presence of OA. Weight loss ranged from 0.3% to 8.3% for treated blocks and from 16.4% to 59.6% for untreated controls. We conclude that SYP treated with these five preservatives limited OA production and prevented decay, and thus confirmed the efficacy of the co-biocides against copper-tolerant fungi.

Methods and Results:The Hagerstown soil was packed into boxes that were 10 cm deep, 30 cm wide and 100, 200 or 300 cm long. Grass was grown in boxes prior experiments. Same-length boxes were placed under rainfall simulator and tilted to have with either 2% or 4% slopes. Dairy manure was broadcast on the upper 30-cm section. Rainfall was simulated and runoff samples were collected and analysed for Cl, FC and total phosphorus (TP). Mass recovery, the concentration decrease rate k, and the ratio FC : TP showed that there was a consistent relationship between FC and TP in runoff. Conclusion:The FC and TP transport through simulated vegetated buffer strips were highly correlated. Significance and Impact of the Study:As a knowledge base on the effect of the environmental parameters on P transport in vegetated buffer strips is substantially larger than for manure-borne bacteria, the observed similarity may enhance ability to assess the efficiency of the vegetated buffer strips in retention of FC currently used as indicator organisms for manure-borne pathogens.

The predictive ability of spaceborne soil moisture retrievals is objectively compared to that obtainable using only available rainfall observations and the antecedent precipitation index (API). The assimilation of spaceborne observations into an API soil moisture proxy is demonstrated to add skill to the forecasting of land surface response to precipitation.

AN - 68448736; 16076104 AB - Gossypol occurs as a mixture of enantiomers in cottonseed. These enantiomers exhibit different biological activities. The (-)-enantiomer is toxic to animals, but it has potential medicinal uses. Therefore, cottonseed with >95% (-)-gossypol could have biopharmaceutical applications. The (+)-enantiomer shows little, if any, toxicity to nonruminant animals. Thus, cottonseed with >95% (+)-gossypol could be more readily utilized as a feed for nonruminants. The (+)- to (-)-gossypol ratio in commercial Upland (Gossypium hirsutum) cottonseed is usually about 3:2, whereas that in commercial Pima cottonseed (Gossypium barbadense) is approximately 2:3. Herein are reported the (+)- to (-)-gossypol ratios in the seed from 28 wild species of cotton (194 accessions), 94 accessions of G. hirsutum var. marie-galante, and 3 domesticated species (11 accessions). It was found that some or all of the accessions of Gossypium darwinii, Gossypium sturtianum, Gossypium areysianum, Gossypium longicalyx, Gossypium harknessii, and Gossypium costulatum produce an excess of (-)-gossypol but none >65%. At least one accession of Gossypium anomalum, Gossypium mustelinum, Gossypium gossypioides, and Gossypium capitis-viridis contained >94% (+)-gossypol. One of the 94 accessions of G. hirsutum var. marie-galante (i.e., no. 2469) contained 97% (+)-gossypol.

Both modeling systems were applied to an ozone episode that occurred along the 1-5 urban corridor in western Washington and Oregon during July 11-14, 1996. Both models employed the same modeling domain and used the same detailed gridded emission inventory. The CMAQ model was run using both the CB-IV and RADM2 chemical mechanisms, while CALGRID was used with the SAPRC-97 chemical mechanism. Output from the Mesoscale Meteorological Model (MM5) employed with observational nudging was used in both models. The two modeling systems, representing three chemical mechanisms and two sets of meteorological inputs, were evaluated in terms of statistical performance measures for both 1- and 8-h average observed ozone concentrations. The results showed that the different versions of the systems were more similar than different, and all versions performed well in the Portland region and downwind of Seattle but performed poorly in the more rural region north of Seattle. Improving the meteorological input into the CALGRID/CALMET system with planetary boundary layer (PBL) parameters from the Models-3/CMAQ meteorology preprocessor (MCIP) improved the performance of the CALGRID/CALMET system. The 8-h ensemble case was often the best performer of all the cases indicating that the models perform better over longer analysis periods. The 1-h ensemble case, derived from all runs, was not necessarily an improvement over the five individual cases, but the standard deviation about the mean provided a measure of overall modeling uncertainty. Process analysis was applied to examine the contribution of the individual processes to the species conservation equation. The process analysis results indicated that the two modeling systems arrive at similar solutions by very different means. Transport rates are faster and exhibit greater fluctuations in the CMAQ cases than in the CALGRID cases, which lead to different placement of the urban ozone plumes. The CALGRID cases, which rely on the SAPRC97 chemical mechanism, exhibited a greater diurnal production/loss cycle of ozone concentrations per hour compared to either the RADM2 or CBIV chemical mechanisms in the CMAQ cases. These results demonstrate the need for specialized process field measurements to confirm whether we are modeling ozone with valid processes.

The toxicity of fumonisin B sub(1) (FB) from culture material with and without activated carbon was evaluated using weanling piglets. Fifty-six weanling pigs were assigned to one of four treatments diets based on BW. The treatment diets were 1) control = corn-soybean basal diet with <2 ppm FB; 2) AC = control + activated carbon at 1% of the diet, as fed; 3) FB = control + culture material (formulated to contain 30 ppm FB, as-fed basis); and 4) AC + FB = control + activated carbon at 1% of the diet as fed + culture material (formulated to contain 30 ppm FB). A total of four replicates of four pigs per pen for the control and AC treatments and three piglets per pen for the FB and AC + FB treatments were used. Feed and water were offered ad libitum for the duration of the 42-d experiment. Compared with pigs fed the control or AC diets, pigs receiving the two FB-contaminated diets (FB or AC + FB) had lower G:F (P < 0.01), higher serum enzyme activities of gamma -glutamyltransferase and glutamic oxaloacetic transaminase (P < 0.05), and higher concentrations of cholesterol, free sphinganine, sphingosine-1-phosphate, and sphinganine 1-phosphate (P < 0.05). Although animals consuming FB diets showed no signs of respiratory distress, all pigs consuming either the FB or the AC + FB diets had marked pulmonary edema. Lesions were observed in the lungs, heart, and liver of pigs fed the FB or AC + FB diets, and treatment-associated changes also were seen in the pancreas, intestines, spleen, and lymph nodes. No lesions were observed in the brain. In liver, lung, heart, pancreas, spleen, intestines, and lymph nodes, the histopathological effects observed were more severe in the AC + FB group, suggesting that the AC treatment worsened the toxic effects of FB. Additionally, immunological measurements of macrophage function (CD14) were affected (P < 0.05) by the consumption of the FB diets. The consumption of FB diets containing 30 ppm fumonisin B sub(1) from cultured material significantly affected performance, biochemical measurements, and organ pathology in weanling pigs. The addition of activated carbon at the rate of 1% to the diet was not effective in protecting against the detrimental effects of fumonisin consumption.

Argentine bluegrass has a bunch-type growth habit, fine upright leaves and does not produce rhizomes. Texas bluegrass spreads by rhizomes and has wider, longer leaves. In an effort to produce novel germplasm with forage or turf potential, experiments were conducted to determine whether hybrid seed could be produced. Crosses were made using pollen from an Argentine male to fertilize two Texas female plants. Parents were induced to flower in the greenhouse by extending the photoperiod to 18 h with 400 W high-pressure sodium lamps from late December to April. The two crosses produced >200 seeds each. Hybrid seedlings segregated for traits from both parents. A sorghum-derived SSR marker confirmed the hybrid nature of a group of seedlings. Seeds harvested from F sub(1) plants using Texas or Texas x Argentine pollen lost the undesirable cottony characteristic of Texas bluegrass. Evaluations for forage and turf potential of hybrid and later generation seed are planned.

Congressional direction for administration of the forest reserves, now called national forests, began in 1897 with passage of the Organic Administration Act. One of the defined purposes for which federal forest lands were set aside from settlement was "securing favorable conditions of water flow." Since then, more than 25 other federal statutes have further defined watershed management on these lands. The Research branch began watershed experiments in 1910 and did most of the watershed work by the Forest Service until the 1970s. Contributions of key individuals, the Civilian Conservation Corps, the barometer watershed program of the 1960s, and other programs in the National Forest System and the State and Private Forestry branches are examined.

In a preliminary study, high binding of antibodies from N. caninum-negative cows was observed in enzyme-linked immunosorbent assay (ELISA) using NiNTA-purified NcGRA6. Analysis of NiNTA eluates revealed a significant number of E. coli proteins that co-purified with recombinant NcGRA6. In an attempt to improve the relative sensitivity and specificity of the NcGRA6-based ELISA, the rNcGRA6 eluates were subjected to a secondary purification using reverse phase-high performance liquid chromatography (RP-HPLC). Analysis of RP-HPLC eluates by SDS-PAGE/silver staining revealed the purification of recombinant NcGRA6 from contaminating E. coli proteins. ELISAs using the RP-HPLC purified NcGRA6 (dELISA) or singly purified NcGRA6 (sELISA) for identifying seropositive and seronegative cows in a beef herd experiencing an epidemic outbreak of neosporosis were compared to standard assays based on native tachyzoite protein- immunofluorescence antibody test, immunoblot assay, and ISCOM-ELISA. The relative sensitivity, specificity, and kappa value of the NcGRA6d-ELISA were greatly improved over the NcGRA6s-ELISA when compared to the three native antigen immunoassays. These results indicate that removal of contaminating E. coli proteins improves the performance of recombinant NcGRA6 ELISA in diagnosing bovine neosporosis, and may have applicability to the use of recombinant proteins in diagnosing other infectious agents.

In addition to providing a reliable source of native plant material, they have also been a source of research and technology transfer in seedling production and quality. Today, Forest Service nurseries face difficult times due to sharp declines in reforestation seedling orders, but strive to respond to increased demand for a wide variety of native plants for ecosystem restoration.

The effect of sprinkling water on the incidence of zoonotic pathogens has not been previously studied. Four pens of heifers (n = 41) were cooled using sprinklers, and four pens (n = 43) served as controls. Heifers were crossbred Charolais, with white and red hair coats. Sprinkling was initiated when cattle were on full concentrate feed (July). Fecal samples, hide swipes, and BW were collected on d 0, 28, 63, 95, and 98. Average daily gain, DMI, and G:F were calculated, and carcass traits were collected 36 h after processing. Performance data were analyzed as a randomized complete block design, and zoonotic pathogen data were analyzed using chi super(2) analysis. Sprinkling tended (P = 0.054) to increase the incidence of fecal Salmonella spp. populations on d 98, but simultaneously tended to decrease (P = 0.058) the Escherichia coli O157:H7 incidence on hides on d 98. The most prevalent Salmonella serovars in this study were Kentucky, Muenster, Meleagridis, and Cerro. Performance measures and carcass traits did not differ between treatments (P > 0.10). Under our conditions, sprinkling cattle with water did not affect the incidence of zoonotic pathogens in feces or on hides.

In these periods SST anomalies are concentrated significantly more toward the International Dateline than usual. We show here that the seasonal weather anomalies typically associated with these additional 'Dateline el Nino' seasons are different in useful respects over much of the world, and suggest that it is useful to treat these as different types of 'El Nino' for purposes of seasonal weather forecasting.

However, recent research has shown that winter can be an especially important period for ecological processes, providing evidence that "dormant season" is a misnomer. Uncertainties about the effects of climate change on ecosystems are highlighting the need for a more thorough understanding of winter ecology. The failure to collect winter data in northeastern North America has meant that researchers are ill-equipped to make predictions about how ecosystems will respond to future climate change. A more focused, integrative ecological winter monitoring and research effort will enable us to better prepare for, and respond to, future climate change.

In response to this initiative, the Forest Inventory and Analysis (FIA) and Forest Health Monitoring (FHM) programs of the United States Department of Agriculture Forest Service have implemented soil measurements as part of a national monitoring program to address specific questions related to the conservation of soil and water resources. Integration of soil assessments into the national FIA program provides for systematic monitoring of soil properties across all forested regions of the U.S. using standardized collection, laboratory, and statistical procedures that are compatible with existing forest inventory data. The resulting information will provide quantitative benchmarks for regional, national, and international reporting on sustainable forest management and enhance our understanding of management effects on soil quality. This paper presents an overview of the FIA soil monitoring program, outlines the field and laboratory protocols as currently implemented, and provides examples of how these data may be used to assess indicators of sustainable management as defined by the Montreal Process.

No DNA hybridization differences were found between two phage type 13A (PT13A) strains that varied in biofilm formation; however, the ribotype patterns were different. Both PT13A strains had DNA sequences similar to that of bacteriophage Fels2, whereas the PT4 genome to which they were compared, as well as a PT4 field isolate, had a DNA sequence with some similarity to the bacteriophage ST64b sequence. Phenotype MicroArray analysis indicated that the two PT13A strains and the PT4 field isolate had similar respiratory activity profiles at 37 degree C. However, the wild-type S. enterica serovar Enteritidis PT13A strain grew significantly better in 20% more of the 1,920 conditions tested when it was assayed at 25 degree C than the biofilm-forming PT13A strain grew. Statistical analysis of the respiratory activity suggested that S. enterica serovar Enteritidis PT4 had a temperature-influenced dimorphic metabolism which at 25 degree C somewhat resembled the profile of the biofilm-forming PT13A strain and that at 37 degree C the metabolism was nearly identical to that of the wild-type PT13A strain. Although it is possible that lysogenic bacteriophage alter the balance of phage types on a farm either by lytic competition or by altering the metabolic processes of the host cell in subtle ways, the different physiologies of the S. enterica serovar Enteritidis strains correlated most closely with minor, rather than major, genomic changes. These results strongly suggest that the pandemic of egg-associated human salmonellosis that came into prominence in the 1980s is primarily an example of bacterial adaptive radiation that affects the safety of the food supply.

A collection of tumours induced by inoculation of specific strains of MDV, ALV and REV, alone or in combination, were tested for quantification of MDV DNA by real-time polymerase chain reaction, expression of the MDV oncogene Meq, expression of several cell markers associated with transformation (CD30, Marek's disease-associated surface antigen, and p53), and level of DNA methylation in the tumour cells. In addition, tissues latently infected with MDV and non-infected tissues were tested as controls. Tumours induced by MDV had about 10 super(2)-fold more copies of MDV DNA than either tissues latently infected by MDV or tumours induced by retrovirus in MDV-vaccinated chickens. Moreover, the MDV antigen Meq was consistently expressed in all MDV tumours but it could not be detected in tissues latently infected with MDV or in tumours induced by retrovirus in MDV-vaccinated chickens. Other markers studied were not specific for MDV and therefore had limited value for diagnosis. Nonetheless, some of these markers might have potential value in research as they will help to identify transformed cells.

The efficacy of alternative chemicals applied by drip irrigation was tested in a cut-flower production system. In 2002, seven chemical formulations were tested: chloropicrin, iodomethane + chloropicrin, 1,3-dichloropropene + chloropicrin, sodium azide, metham sodium, furfural + allyl isothiocyanate, and furfural + metham sodium. In 2003, an additional treatment, dimethyl disulfide, was added. Most treatments reduced populations of Pythium ultimum and Fusarium oxysporum and increased stem height compared with the nontreated controls. Metham sodium, furfural + metham sodium, sodium azide, and chloropicrin significantly reduced incidence of Liatris stem rot caused by Sclerotinia sclerotiorum. Weed control was not acceptable either year for any treatments. Viable alternatives to MB for cut-flower production will require better treatments for weed control than was achieved in this study.

In the NPA, safflower production is being evaluated for potential rotation with sugar beet. Safflower is susceptible to Cercospora carthami, whereas sugar beet is susceptible to C. beticola, C. carthami has not been observed on safflower in the NPA but C. beticola is ubiquitous on sugar beet. Observation of unusual leaf spots on irrigated safflower cv. Centennial at Sidney, MT prompted this investigation of safflower as a potential alternate host of C. beticola. Safflower plants were inoculated with four isolates of C. beticola (C1, C2, Sid1, and Sid2) and incubated in growth chambers; leaf spot symptoms appeared between 3 and 4 weeks later. Polymerase chain reaction (PCR) amplification of extracts from lesion leaf tissue with C. beticola-specific primers produced fragments comparable with amplified fragments from purified cultures of control C. beticola. PCR assay of cultures of single spores from diseased safflower leaf lesions also produced fragments comparable with fragments from C. beticola cultures. Antibody that was raised from isolate C2 also bound to antigens from the single-spore cultures of the four C. beticola isolates. Inoculum from single-spore cultures from infected safflower also infected sugar beet and produced typical Cercospora leaf spot symptoms. Assay of these leaf lesions by PCR resulted in amplification of target fragments with the C. beticola-specific primers. Our results demonstrate that safflower is a new host of C. beticola.

The progression of TSWV infection was examined through the season using enzyme-linked immunosorbent assay (ELISA) tests on different tissue types [roots, leaves, pegs (pod attachment stem structures) and pods] and the effect of TSWV infection on physiological functions was examined at three harvest dates. Plants were classed into three severity categories: (i) no TSWV symptoms or previous positive ELISA tests; (ii) less than 50% of leaf tissue exhibiting TSWV symptoms; and (iii) greater than 50% of leaf tissue affected. TSWV showed a slow rate of infection at the beginning of the season and a greater percentage of infection of the roots than in the leaves. Photosynthesis was reduced in virus-affected infected plants by an average of 30% at the mid-season harvest and 51% at the late season harvest compared with virus-free plants across all three cultivars. Leaf tissue with symptoms had lower photosynthetic rates than healthy leaves. There were small differences among cultivars, with cv. ANorden maintaining higher average photosynthetic levels than cv. Georgia Green and higher transpirational levels than cv. NC-V11. The ability to maintain high assimilation physiology in the presence of the virus may help cultivars withstand TSWV infection and maintain final yields.

Information on the distribution of carnivores from the early 1900s provides a unique opportunity to evaluate changes in their distributions over a 75-year period during which the influence of human uses of forest resources in California greatly increased. We present information on the distributions of forest carnivores in the context of two of the most significant changes in the Sierra Nevada during this period: the expansion of human settlement and the reduction in mature forests by timber harvest. Methods: We compare the historical and contemporary distributions of 10 taxa of mesocarnivores in the conifer forests of the Sierra Nevada and southern Cascade Range by contrasting the distribution of museum and fur harvest records from the early 1900s with the distribution of detections from baited track-plate and camera surveys conducted from 1996 to 2002. A total of 344 sample units (6 track plates and 1 camera each) were distributed systematically across c. 3,000,000 ha area over a 7-year period. Results: Two species, the wolverine (Gulo gulo) and the red fox (Vulpes vulpes), present in the historical record for our survey area, were not detected during the contemporary surveys. The distributions of 3 species (fisher [Martespennanti], American marten [M. americana], and Virginia opossum [Didelphisvirginiana]) have substantially changed since the early 1900s. The distributions of fishers and martens, mature-forest specialists, appeared to have decreased in the northern Sierra Nevada and southern Cascade region. A reputed gap in the current distribution of fishers was confirmed. We report for the first time evidence that the distribution of martens has become fragmented in the southern Cascades and northern Sierra Nevada. The opossum, an introduced marsupial, expanded its distribution in the Sierra Nevada significantly since it was introduced to the south-central coast region of California in the 1930s. There did not appear to be any changes in the distributions of the species that were considered habitat generalists: gray fox (Urocyon cinereoargenteus), striped skunk (Mephitis mephitis), western spotted skunk (Spilogale gracilis), or black bear (Ursus americanus). Detections of raccoons (Procyon lotor) and badgers (Taxidea taxus) were too rare to evaluate. Contemporary surveys indicated that weasels (M. frenata and M. erminea) were distributed throughout the study area, but historical data were not available for comparison. Main conclusions: Two species, the wolverine and Sierra Nevada red fox, were not detected in contemporary surveys and may be extirpated or in extremely low densities in the regions sampled. The distributions of the mature forest specialists (marten and fisher) appear to have changed more than the distributions of the forest generalists. This is most likely due to a combination of loss of mature forest habitat, residential development and the latent effects of commercial trapping. Biological characteristics of individual species, in combination with the effect of human activities, appear to have combined to affect the current distributions of carnivores in the Sierra Nevada. Periodic resampling of the distributions of carnivores in California, via remote detection methods, is an efficient means for monitoring the status of their populations.

Chemical Surveys AN - 17645477; 6437813 AB - The National Institute for Occupational Safety and Health (NIOSH) conducted a series of surveys to evaluate occupational exposure to noise and potentially ototoxic chemical agents among members of a professional stock car racing team. Exposure assessments included site visits to the team's race shop and a worst-case scenario racetrack. During site visits to the race team's shop, area samples were collected to measure exposures to potentially ototoxic chemicals, including, organic compounds (typical of solvents), metals, and carbon monoxide (CO). Exposures to these chemicals were all below their corresponding Occupational Safety and Health Administration (OSHA) permissible exposure limits (PELs), NIOSH recommended exposure limits (RELs), and American Conference of Governmental Industrial Hygienists (ACGIH registered ) threshold limit values (TLVs registered ). During site visits to the racetrack, area and personal samples were collected for organic compounds, lead, and CO in and around the "pit" area where the cars undergo race preparation and service during the race. Exposures to organic compounds and lead were either nondetectable or too low to quantify. Twenty-five percent of the CO time-weighted average concentrations exceeded the OSHA PEL, NIOSH REL, and ACGIH TLV after being adjusted for a 10-hour workday. Peak CO measurements exceeded the NIOSH recommended ceiling limit of 200 ppm. Based on these data, exposures to potentially ototoxic chemicals are probably not high enough to produce an adverse effect greater than that produced by the high sound pressure levels alone. However, carbon monoxide levels occasionally exceeded all evaluation criteria at the racetrack.

The impact of leaving infected trees on the rate of CTV spread was determined by comparing temporal incidence of CTV in plots in Strathmore, Tulare County without eradication with incidence in a plot in McFarland, Kern County with eradication. From 1997 to 2003, CTV incidence in the Strathmore plots ranged from 6 to 42%, with annual spread rates from 1.6 to 3.6%. CTV incidence in the McFarland plot increased from 0 to 5% between 2001 and 2003 before infected trees were removed. Using a subplot hierarchical bulk sampling method, virus incidence over a 3-year period in a 6.5 km super(2) area near McFarland was estimated to range from 0.09 to 0.69%, which indicated that CTV suppression was still being achieved in this area. Vector tests using the cotton aphid, Aphis gossypii, identified highly transmissible isolates (30 to 61% transmission rate) and a larger proportion of highly transmissible isolates were found in the McFarland plots. Thirty-six CTV isolates from recently infected plot trees were obtained and analyzed. None of these isolates reacted with monoclonal antibody MCA13 that detects presumptive CTV severe strains. Molecular analysis using polymerase chain reaction and sequence-specific primers showed that all isolates had a genotype identical to the T30 mild isolate from Florida.

AN - 17645045; 6464361 AB - We employed standardized measurement techniques and protocols to describe the size dependence of whole-tree water use and cross-sectional area of conducting xylem (sapwood) among several species of angiosperms and conifers. The results were not inconsistent with previously proposed 3/4-power scaling of water transport with estimated above-ground biomass. However, for a given size, angiosperms transported considerably greater quantities of water than conifers. In the angiosperms studied, the scaling of water transport with sapwood area, stem diameter and above-ground biomass was best described by sigmoid functions rather than a power function, consistent with the previously reported size dependence of other processes such as growth. At least three distinct species groupings for relationships between sapwood area and stem basal area were observed. Scaling of sapwood area with stem radius was well described by a power function of the form Y = Y sub(0)X super(b). However, exponents obtained for two of the three species groups differed significantly from a recently proposed theoretical value of 2.33.

Previous work has shown that transmission of some insect pathogens is a non-linear process. A number of hypotheses have been put forward as explanations for this phenomenon; however, none have proven wholly satisfactory. Here we test the effects on transmission of spatial distribution of an insect virus by testing whether or not experimental manipulations of pathogen clumping lead to different values of a clumping parameter. The gypsy moth nucleopolyhedrovirus (LdMNPV) was used, which is transmitted when larvae consume virus released from previously infected larvae that have died on foliage. 2. It was found that even when virus densities on foliage were equal, overall mortality was lower when virus-killed cadavers were clumped on foliage. 3. Non-linearity is more pronounced when cadavers are clumped than when they are placed at random on the foliage. Placement of droplets containing LdMNPV on foliage resulted in more linear transmission compared with cadavers. 4. Spatial clumping of viral inoculum thus provides part of the explanation for non-linear transmission in this system. The ultimate explanation for non-linear transmission is likely to involve some combination of spatial clumping and heterogeneity in behaviours such as feeding rate or the ability to avoid pathogen.

Methods and Results:Isolates were tested for antimicrobial susceptibility using the E-test method. Approximately 60% (n = 267) were resistant to one or more antimicrobials, and 19.6% (n = 88) were resistant to two or more antimicrobials. Of the Campylobacter jejuni isolates, 49.1% (n = 187) were resistant to tetracycline, 10.2% (n = 39) were resistant to nalidixic acid, 8.4% were resistant to trimethoprim/sulfamethoxazole, and 1.8% (n = 7) were resistant to ciprofloxacin. Resistance to any of the other eight antimicrobials was 1.3% or less, but 14.4% (n = 55) were resistant to two or more antimicrobials. In the Campylobacter coli group, 65.7% (n = 44) were resistant to tetracycline, 52.2% (n = 35) were resistant to trimethoprim/sulfamethoxazole, 22.4% (n = 15) were resistant to nalidixic acid, and 9.0% (n = 6) were resistant to ciprofloxacin. Resistance to any of the remaining eight antimicrobials was 3.0% or less, although 49.3% (n = 33) were resistant to two or more antimicrobials. Conclusions:Although antimicrobials are widely used in US feedlot cattle production, our results demonstrate generally low levels of resistance to a broad range of commonly used antimicrobials relative to other recent studies. Significance and Impact of the Study:Resistance data on Campylobacter isolated from this major US livestock commodity is lacking. This overview enhances current knowledge and provides a basis for further studies.

Accordingly, the organism has developed at least three genetically and physiologically distinct acid resistance systems which provide different levels of protection. The glutamate-dependent acid resistance (GDAR) system utilizes extracellular glutamate to protect cells during extreme acid challenges and is believed to provide the highest protection from stomach acidity. In this study, the GDAR system of 82 pathogenic E. coli isolates from 34 countries and 23 states within the United States was examined. Twenty-nine isolates were found to be defective in inducing GDAR under aerobic growth conditions, while five other isolates were defective in GDAR under aerobic, as well as fermentative, growth conditions. We introduced rpoS on a low-copy-number plasmid into 26 isolates and were able to restore GDAR in 20 acid-sensitive isolates under aerobic growth conditions. Four isolates were found to be defective in the newly discovered LuxR-like regulator GadE (formerly YhiE). Defects in other isolates could be due to a mutation(s) in a gene(s) with an as yet undefined role in acid resistance since GadE and/or RpoS could not restore acid resistance. These results show that in addition to mutant alleles of rpoS, mutations in gadE exist in natural populations of pathogenic E. coli. Such mutations most likely alter the infectivity of individual isolates and may play a significant role in determining the infective dose of enterohemorrhagic E. coli.

The paradigm for this multiresistant/hyperpathogenic phenotype is Salmonella enterica serotype Typhimurium phage type DT104 (DT104). The basis for the multiresistance in DT104 is related to an integron structure designated SGI1, but factors underlying hyperpathogenicity have not been completely identified. Since protozoa have been implicated in the alteration of virulence in Legionella and Mycobacterium spp., we attempted to assess the possibility that protozoa may contribute to the putative hypervirulence of DT104. Our study reveals that DT104 can be more invasive, as determined by a tissue culture invasion assay, after surviving within protozoa originating from the bovine rumen. The enhancement of invasion was correlated with hypervirulence in a bovine infection model in which we observed a more rapid progression of disease and a greater recovery rate for the pathogen. Fewer DT104 cells were recovered from tissues of infected animals when protozoa were lysed by preinfection chemical defaunation of the bovine or ovine rumen. The protozoan-mediated hypervirulence phenotype was observed only in DT104 and other Salmonella strains, including serovars Agona and Infantis, possessing SGI1.

It has been previously shown to have anti-Staphylococcus aureus activities. In this work, the effect of Phloxine B on various gram-negative bacteria and other gram-positive bacteria including Bacillus cereus, Bacillus thuringiensis, Bacillus mycoides, Bacillus subtilis, Bacillus aureus, Salmonella, Escherichia coli and Shigella was studied, along with the mechanism of anti-microbial activity. In the presence of fluorescent light, the viable count for gram-positive bacteria, (Bacillus spp. and S. aureus) decreased in a dose and time dependent manner when incubated with Phloxine B. The viability of gram-positive bacteria was reduced by 99.99% in 40min, while there was no effect on gram-negative bacteria (Salmonella choleraesuis, E. coli and Shigella flexneri). However, the use of ethylenediaminetetraacetic acid (EDTA) expands the spectrum of activity for Phloxine B to include gram-negative bacteria. EDTA increased membrane-permeability by releasing lipopolysaccharide. Overall, in an Agar diffusion test the light-dependent bactericidal activity of 1 mu g of Phloxine B had a potency of 0.64 units of chloramphenicol and 0.5 units of tetracycline when tested on B. cereus, and had a potency of 0.7 units of chloramphenicol and 0.2 units of tetracycline when tested on S. aureus. The data suggest that the dye may have some potential anti-microbial applications.

At 15 and 40 degree C, eggs did not develop and sustained 100% mortality. Similarly, larvae at 15 degree C and pupae at 40 degree C did not develop and sustained 100% mortality. For all three larval stages, the developmental time decreased with increasing temperature between 20 and 35 degree C and increased at 40 degree C. Developmental times also decreased with increasing temperature between 20 and 35 degree C for the pupal stage as did total developmental time from egg to adult. Both linear and nonlinear models were used to describe the relationship between developmental rates (1/d) and temperature ( degree C) and to determine stage-specific lower and upper developmental thresholds, respectively. The lower developmental thresholds, calculated using the linear model, ranged from 6 to 15 degree C for all life stages. Using the nonlinear model, the lower developmental thresholds ranged from 15 to 18 degree C for all life stages. Likewise, the high temperature thresholds for the first-, second-, and third-instar larvae, pupae, and total development ranged between 40 and 42 degree C. Results from this study were used to enhance the efficiency of mass-rearing methods for open field releases of D. elongata in California. More importantly, this study is the first step in the construction of a detailed population simulation model to predict field phenology and density of D. elongata to further optimize the use of this biological control agent in managing saltcedar in the western United States.

Methods and Results:Animals were fed over three dietary phases to match production needs from age 10-14 weeks, 14-18 weeks and 18-22 weeks. For each feeding phase, diets were formulated to contain 0 or 10% DSM (balanced for metabolizable energy and true ileal digestible amino acids). Animals were weighed every 2 weeks and faecal samples were collected from 40 animals (20 with DSM and 20 without DSM) at week 10 (d 0 on diets), 14, 18 and 22 of age, and were analysed for Lactobacillus spp., Enterobacteriaceae, coliforms, E. coli, Salmonella, Campylobacter and E. coli O157:H7. At the start of the study (week 10), faecal bacterial counts (log sub(10) CFU g super(-1) faeces) were 9.55, 7.26, 7.01 and 6.93 for Lactobacillus, Enterobacteriaceae, coliforms and E. coli populations respectively. The Enterobacteriaceae, coliform and E. coli populations decreased through week 14 and 18, but were higher in animals fed with the DSM diet compared with the basal diet without DSM. The Lactobacillus populations at weeks 14 and 18 were lower in the animals fed the diet without DSM, whereas feeding DSM maintained the Lactobacillus counts from week 10. At week 22, populations of Enterobacteriaceae, coliforms and E. coli were >week 18 for the animals fed the diet without DSM, less change was observed with the feeding of DSM, and no differences between the diets were observed at week 22. However, in week 22 the animal gain was positively correlated with Lactobacillus numbers and negatively correlated with E. coli numbers. Subtraction of the E. coli population (log sub(10)) from the Lactobacillus population (log sub(10)) yielded a positive value termed 'effective'Lactobacillus that correlated well with animal gain and may better define a beneficial function in the intestine. Salmonella were detected in over 60% of the animals at week 10 and 14, and <20% at week 18 and 22. Campylobacter were detected rarely at weeks 10, 14 and 18, but were found in 25% of the animals at week 22. The DSM did not affect Salmonella or Campylobacter shedding, but examination of individual animals over the entire experiment indicated that fewer recurring incidences of Salmonella shedding occurred in animals that maintained higher Lactobacillus. In addition, at week 22, Salmonella and Campylobacter shedding was associated with lower levels of effective Lactobacillus and lower animal weight gains. Conclusions:The DSM did not directly affect the animal performance or pathogen shedding via the Lactobacillus spp. population at any phase of production. However, analysis of data from all animals revealed that faecal Lactobacillus affected Salmonella shedding and in the finishing phase, animal growth and pathogen shedding also were affected, as reflected by the 'effective'Lactobacillus-associated observations. Significance and Impact of the Study:In the swine intestine, any benefits from gastrointestinal Lactobacillus may be compromized by the E. coli population, and this antagonism may explain responses observed with prebiotics or probiotics in some swine.

Palmer amaranth pigweed, Amaranthus palmeri S. Wats., was grown under 25% of full watering (water deficit), 30% of full light (shade), or combined stress. All treatments decreased plant height and weight. Shade and combined stresses decreased leaf counts and increased leaf water content. Water deficit stress increased leaf water potential, soluble protein and carbohydrate contents, peroxidase activities, and accumulations of 10 individual free amino acids (FAAs), summed essential FAAs, and total FAAs. Combined stress increased water potential, soluble carbohydrates, 12 individual FAAs, summed essential FAAs, and total FAAs. Shade stress decreased water potential, soluble carbohydrates, seven individual FAAs, and essential FAAs. Beet armyworm larvae consumed similar leaf areas on water deficit-stressed and nonstressed plants and larger areas on plants grown under shade or combined stress. Larval survival was reduced, and time to pupation was higher on shade-stressed leaves. Adult females deposited more eggs on shade and combined stress plants and fewer eggs on water deficit-stressed plants compared with controls. Beet armyworm feeding and oviposition responded to variation in water content. Stress-induced changes in nutrients were not tied to insect preference but could have negatively influenced survival under shade stress. The results have implications for the plant stress hypothesis and for the use of pigweeds for beet armyworm detection.

Synthetic host plant volatiles evaluated included (1) those identified from foliar and woody tissues of a nonfruiting Stanley plum tree (6-Tree) or the two major components (2-Tree); (2) those identified from Stanley plum fruit (7-Plum) or two components eliciting positive GC-EAD response from plum curculios (2-Plum); and (3) benzaldehyde formulated into rubber septa and replaced weekly [Ben(s)] or dispensed into polyethylene vials and replaced weekly [Ben(r)], not replaced [Ben(nr)], and formulated with 10% 1,2,4-trichlorobenzene and not replaced [Ben(TCB)]. In 2003, the greatest numbers of plum curculios were captured in traps baited with 6-Tree + GA and Ben(TCB) + GA, with responses to these baits significantly greater than responses to unbaited control traps. In 2004, the greatest number of plum curculios was captured in traps baited with 6-Tree(h) (high release rate dispenser) + Ben(TCB) + GA, with response to this bait significantly greater than responses to unbaited traps. Combined results indicate that volatiles released by foliar and woody tissues of plum are at least as attractive as the single fruit-based attractant, benzaldehyde, when combined with GA and point toward more competitive attractants for plum curculio based on multiple component blends of volatiles released by the entire tree.

Insects were allowed to mate and lay eggs, and all eggsticks were collected daily. Percent egg hatch and reduction in F sub(1) fertile larvae were used to ascertain the effectiveness of each release combination. In addition, limited field release-recapture experiments were conducted to examine the dispersal ability of untreated and treated cactus moth males. Results suggest that an overflooding ratio as low as 5:1 can effectively suppress C. cactorum in field cages and that releasing both genders together is more effective than releasing males only. In open field releases, the dispersal ability of C. cactorum was not significantly affected by treating the adults with gamma radiation.

The Tasseled Cap (TC) transformation for Landsat data has been used in several disturbance-mapping projects because of its ability to highlight relevant vegetation changes. We used an automated composite analysis procedure to test four multi-date variants of the TC transformation (called "data structures" here) in their ability to facilitate identification of stand- replacing disturbance. Data structures tested included one with all three TC indices (brightness, greenness, wetness), one with just brightness and greenness, one with just wetness, and one called the Disturbance Index (DI) which is a novel combination of the three TC indices. Data structures were tested in the St. Petersburg region of Russia and in two ecologically distinct regions of Washington State in the US. In almost all cases, the TC variants produced more accurate change classifications than multi-date stacks of the original Landsat reflectance data. In general, there was little overall difference between the TC-derived data structures. However, di performed better than the others at the Russian study area, where slower succession rates likely produce the most durable disturbance signal. Also, at the highly productive western Washington site, where the disturbance signal is likely the most ephemeral, di and wetness performed worse than the larger data structures when a longer monitoring interval was used (eight years between image acquisitions instead of four). This suggests that both local forest recovery rates and the re-sampling interval should be considered in choosing a Landsat transformation for use in stand-replacing disturbance detection.

The aluminium amounts released by used extraction procedures were valuated and discussed. The new indicative values of fractional Al concentrations in five Chinese certified reference materials (GBW 07103, 07304, 07401, 07405, 07407) were determined after Al fractionation by optimized BCR three-step sequential extraction procedure. The aluminium toxicity indexes calculated for two different soil extracts and plant samples were used for assessment of Al toxicity to plants. It can be concluded that the most sensitive indicator of increasing aluminium toxicity to plants is determination of reactive Al species in soil solution by chelating ion-exchange solid phase extraction. The atomic absorption spectrometry with nitrous oxide-acetylene flame was used for determination of total Al amounts and the Al concentration in different extraction fractions as well.

The large cervid population, the popularity of venison consumption, and the apparent spread of the CWD epidemic are likely resulting in increased human exposure to CWD in the United States. Whether CWD is transmissible to humans, as has been shown for bovine spongiform encephalopathy (the prion disease of cattle), is unknown. We generated transgenic mice expressing the elk or human prion protein (PrP) in a PrP-null background. After intracerebral inoculation with elk CWD prion, two lines of "humanized" transgenic mice that are susceptible to human prions failed to develop the hallmarks of prion diseases after >657 and >756 d, respectively, whereas the "cervidized" transgenic mice became infected after 118-142 d. These data indicate that there is a substantial species barrier for transmission of elk CWD to humans.

The prominence of public concern about sprawl is germane to planners, managers, and policymakers involved in efforts to protect interface forests from urban encroachment because the level of concern will influence the acceptance of policies and programs aimed at protecting forests. A new indicator of public concern about urban sprawl is presented, based on computer content analysis of public discussion contained in the news media from 1995-2001. More than 36,000 news stories about sprawl were analyzed for expressions of concern. Overall concern about sprawl grew rapidly during the latter half of the 1990s. The environmental impacts of sprawl were the most salient concern overall, and concern about loss of open space and traffic problems has increased since 1995 as a share of all sprawl concerns. The method described in this paper provides a new approach for planners and policymakers to monitor change in public attitudes about a wide range of social issues over time.

More recently, it was found in several human intestinal Bacteroides species. We report here the first finding of ermG genes in gram-positive bacteria isolated from porcine feces and from under-barn manure pits used to store porcine wastes. The porcine ermG sequences were identical to the sequence of the B. sphaericus ermG gene except that six of the seven ermG-containing strains contained an insertion sequence element insertion in the C-terminal end of the gene. The porcine ermG genes were found in three different gram-positive genera, an indication that it is possible that the gene is being spread by horizontal gene transfer. A segment of a Bacteroides conjugative transposon that carries an ermG gene cross-hybridized with DNA from six of the seven porcine isolates, but the restriction patterns in the porcine strains were different from that of the Bacteroides conjugative transposon.

Thirty-four SSR loci were selected for SSR primer design and were validated in PCR experiments. These multilocus SSR primers, distributed across the X. fastidiosa genome, clearly differentiated and clustered X. fastidiosa strains collected from grape, almond, citrus, and oleander. They are well suited for differentiating strains and studying X. fastidiosa epidemiology and population genetics.

Forest susceptibility to maritime windstorms was determined by applying a wind-disturbance model (WINDSTORM) to two study areas where bear dens had been identified by radio telemetry. We evaluated model predictions for forest structure against field data for one study area. As predicted, forests in wind-protected landscapes contained features indicative of later stages of forest development where larger and older trees are more abundant. By contrast, forests located in storm-susceptible locations contained higher tree densities, less variation in tree diameters, smaller trees, and less evidence of large, old trees with heart rot. Analysis of habitat use relative to its availability on the landscape indicates that bears selected wind-protected landscapes over storm-prone landscapes in both study areas for winter dens. The majority (58%) of den sites were located in forests most protected from catastrophic storm effects. By contrast, only 6% were located in forests most exposed to storm damage. Results suggest that forests most protected from catastrophic windstorm disturbance contain more suitable overwinter habitat for black bears as evidenced by den site selection.

One concept to consider is using perennial cows. Perennial cows are those that maintain a relatively high milk production for greater than or equal to 2 yr without going through the typical dry period followed by calving. Farm records show that some cows have produced over 20 kg/d after 4 yr of continuous lactation. A farm simulation model was used to evaluate the long-term performance, environmental impact, and economics of a conceptual perennial cow production system on a typical dairy farm in Pennsylvania. Compared with a traditional 100-cow farm with replacement heifers produced on the farm, a perennial herd of 100 cows and purchased replacements provided environmental benefit but sustained a substantial economic loss. However, increasing the perennial herd to 128 cows better utilized the feed produced on the farm. Compared with the traditional 100-cow farm, use of the perennial 128-cow herd reduced supplemental protein and mineral feed purchases by 38%, increased annual milk sales by 21%, reduced nitrogen losses by 17%, maintained a phosphorus balance, and increased annual net return to farm management by $3200. A traditional 120-cow dairy farm with purchased replacements also used a similar amount of farm-produced feed. Compared with this option, the farm with 128 perennial cows reduced protein and mineral feed purchases by 36%, maintained similar annual milk sales, increased manure production by 7%, reduced N losses by 10%, and increased annual net return by $12,700. The economic feasibility of the perennial-cow dairy farm was very sensitive to the milk production maintained by the perennial herd and market prices for milk and perennial replacement animals. The analysis was relatively insensitive to the assumed useful life of perennial cows as long as they could be maintained in the herd for at least 3 yr. Thus, a perennial cow production system can improve the economic and environmental sustainability of a traditional dairy farm if a similar level in annual milk production per cow can be maintained.

We investigated the effect of calcium on surface appendages of Sinorhizobium fredii USDA257. Cold-field emission scanning electron microscopy observation of USDA257 grown in calcium-limiting conditions revealed cells with unusual shape and size. Transmission electron microscopy observation revealed intact flagella were present only when USDA257 cells were grown in calcium-sufficient conditions. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of flagellar preparations from USDA257 cells grown in calcium-limiting conditions showed the presence of a 22-kDa protein that was absent from cells grown in calcium-sufficient conditions. We have cloned and determined the nucleotide sequence of the gene encoding the 22-kDa protein. After successful expression in Escherichia coli, polyclonal antibodies were raised against the recombinant 22-kDa protein (Omp22). Subcellular fractionation analysis demonstrated that Omp22 was predominantly present in the extracellular fraction. Western blot analysis revealed the presence of immunologically related proteins from diverse rhizobia. Immunocytochemical localization of thin sections of USDA257 cells showed specific labeling of protein A-gold particles on protein inclusions found proximal to the cells. Accumulation of Omp22 was greatly reduced when USDA257 cells were grown in the presence of increasing calcium. Northern blot analysis indicated that calcium was the only divalent cation among those tested that down-regulated omp22 expression. An omp22 mutant was able to grow in calcium-limiting conditions at a rate similar to that of wild-type USDA257. Significantly more nodules were initiated by the omp22 mutant than by the wild-type on soybean cultivar Peking grown in calcium-limiting conditions.

We previously demonstrated that the transgene insert and resistance to PPV were mutually inherited in progeny of line C5. We show here that C5 constitutively produces a short (22 nt) and a long (25 to 26 nt) species of short interfering (si)RNA from embryo to mature plant in the absence of PPV inoculation. Unlike siRNA, methylation and transcription of the PPV-coat protein transgene were `re-set' following seed germination. Uninoculated transgenic susceptible clones did not display DNA methylation, nor did they produce detectable levels of siRNA. Upon infection, susceptible clones, transgenic or untransformed, did produce siRNA but only the short 22-nt species. These findings show that plum trees respond to virus infection by initiating PTGS-like mechanisms that involve the production of siRNA. We further suggest that high-level virus resistance in transgenic Prunus species requires the production of the long-size class of siRNA. The research adds new insights into PTGS silencing in woody perennial plant species.

Most of these models are now available for personal computers and can be used to study the control of irrigation canals. Studies on automatic control methods and algorithms have been performed on at least half a dozen of the available unsteady-flow simulation models. Although, many of these automation studies have been conducted by the institution that created the simulation model, these simulation models were not created with automatic gate control in mind, and thus one has to be intimately familiar with the source code in order to implement sophisticated control features. Three commercially available unsteady-flow simulation software packages that allow automatic control of gates based on algorithms written by users are: CanalCAD from the Univ. of Iowa, Hydraulics Lab; Mike 11 version 3.2 from the Danish Hydraulic Institute; and Sobek from Delft Hydraulics. In this paper, we describe the various features of these unsteady-flow simulation packages and how they interface to control engineering software/code. There are a number of tradeoffs between simplicity and functionality. All these models present difficulties and have limitations. The hope is to provide guidance on the next generation of unsteady-flow canal simulation models so that control functions can be routinely applied.

Global change is a natural resource issue increasingly contributed to by human activities that now joins other important issues facing agricultural scientists, such as depletion of soil organic carbon (SOC), soil degradation and contamination, and pollution of natural waters by soil sediments and nutrients. Increasing demand for food by the growing global population is resulting in increased GHG emissions, soil disturbance, fossil fuel consumption to produce agricultural products, and biomass burning. To address these issues and the threat of accelerated GHG emissions, this paper addresses: (1) current scientific facts about the attributes of soil and natural resources, (2) strategies for sustainable use of our finite, non-renewable, and fragile land resources, and (3) advances made by agricultural sciences and their potential role in forming policy. Site-specific adaptation of appropriate conservation technologies will be needed for sequestering SOC and reducing nitrous oxide (N sub(2)O) emission. Adoption of improved conservation technologies to mitigate GHG emission should consider: (i) the rate of C sequestration or GHG mitigation, (ii) the price offered for adopting various practices, (iii) the ease with which producers and land managers can alter land use and management activities, (iv) the potential impacts of targeting regions or practices, (v) the ancillary benefits to soil, water and air quality upon adoption of practices to sequester SOC or mitigate GHG emission, and (vi) the effectiveness and efficiency of various policies. Development of improved conservation technologies to reduce GHG emissions could become part of more comprehensive conservation programs aimed at environmental protection, food security, and agricultural sustainability. An overarching research need is to determine the multiple benefits and trade-offs of improved conservation technologies so that land managers can systematically meet production and environmental goals and so that the most effective policies can be devised.

Due to the high proportion of land area committed to crops and pasture in this region, the carbon (C) stored and greenhouse gas (GHG) emission due to agriculture represent a large percentage of the total for the USA. Our objective was to summarize potential soil organic C (SOC) sequestration and GHG emission from this region and identify how tillage and cropping system interact to modify these processes. Conservation tillage (CST), including no-tillage (NT), has become more widespread in the region abating erosion and loss of organic rich topsoil and sequestering SOC. The rate of SOC storage in NT compared to conventional tillage (CT) has been significant, but variable, averaging 0.40 plus or minus 0.61 Mg C ha super(-1) year super(-1) (44 treatment pairs). Conversion of previous cropland to grass with the conservation reserve program increased SOC sequestration by 0.56 plus or minus 0.60 Mg C ha super(-1) year super(-1) (five treatment pairs). The relatively few data on GHG emission from cropland and managed grazing land in the central USA suggests a need for more research to better understand the interactions of tillage, cropping system and fertilization on SOC sequestration and GHG emission.

Where water is available, irrigation allows for production of a variety of agricultural and horticultural crops. This review assesses the impacts of agriculture on greenhouse gas emission and sequestration of atmospheric C in soils of the hot, dry region of the southwestern USA. In Texas, conservation tillage increased soil organic C by 0.28 Mg C ha super(-1) year super(-1) compared with more intensive tillage. Conversion of tilled row crops to the conservation reserve program or permanent pastures increased soil organic C by 0.32 plus or minus 0.50 Mg C ha super(-1) year super(-1). Soil organic C sequestration was dependent on rotation, previous cropping, and type of conservation tillage employed. Relatively few studies have interfaced management and C cycling to investigate the impacts of grazing management on soil organic C, and therefore, no estimate of C balance was available. Irrigated crop and pasture land in Idaho had soil organic C content 10-40 Mg C ha super(-1) greater than in dryland, native grassland. Soil salinity must be controlled in cropland as soil organic C content was lower with increasing salinity. Despite 75% of the region's soils being classified as calcic, the potential for sequestration of C as soil carbonate has been only scantly investigated. The region may be a significant sink for atmospheric methane, although in general, trace gas flux from semiarid soils lacks adequate characterization. Agricultural impacts on C cycling will have to be better understood in order for effective C sequestration strategies to emerge.

The EF methodology is currently used for the USA greenhouse gas inventory but process based models, such as DAYCENT, may yield more reliable results because they account for factors such as soil type, climate, and tillage intensity that are ignored by EF. Comparison of mean annual soil N sub(2)O flux estimated by DAYCENT and EF with measured data for different cropping systems yielded r super(2) values of 0.74 and 0.67, and mean deviations of -6 and +13%, respectively. At the national scale, DAYCENT simulation of total N sub(2)O emission was similar to 25% lower than estimated using EF. For both models, N sub(2)O emission was highest in the central USA followed by the northwest, southwest, southeast, and northeast regions. The models simulated roughly equivalent direct N sub(2)O emission from fertilized crops, but EF estimated greater direct N sub(2)O emission than DAYCENT for N-fixing crops. DAYCENT and EF estimates of the gaseous component of indirect N sub(2)O emission (NO + NH sub(3)) differed little, but DAYCENT estimated approximately twice the indirect emission from NO sub(3) leaching since it included the contribution of N from N-fixing crops while EF did not. DAYCENT simulations were also performed for no tillage cropping, pre-1940 crop management, and native vegetation. DAYCENT-simulated N sub(2)O, CO sub(2), and CH sub(4) fluxes were converted to CO sub(2)C equivalents and combined with fuel use estimates to estimate net global warming potential (GWP sub(net)). GWP sub(net) for recent non-rice (Oryza sativa L.) major cropping was 0.43 Mg C ha super(-1) yr super(-1) under conventional tillage and 0.29 Mg C ha super(-1) yr super(-1) under no tillage, for pre-industrial cropping was 0.25 Mg C ha super(-1) yr super(-1), and for native systems was -0.15 Mg C ha super(-1) yr super(-1). Results from DAYCENT suggest that conversion to no tillage at the national scale could mitigate similar to 20% of USA agricultural emission or similar to 1.5% of total USA emission of greenhouse gases.

The primary objectives of GRACEnet are to identify and develop agricultural strategies that will enhance soil C sequestration and reduce greenhouse gas emissions and to provide a scientific basis for possible C credit and trading programs that could be used to reduce net emissions of greenhouse gases and improve environmental quality. This program will generate information on C storage in agricultural systems, which is needed by producers, program managers, and policy makers. Scenarios evaluated in GRACEnet will not only address mitigation of CO sub(2) emission through soil C sequestration, but also their effects on nitrous oxide (N sub(2)O) and methane (CH sub(4)). Both grazing lands (range and pasture) and croplands (irrigated and dryland) will be investigated. The information generated will be applicable at the local (e.g., farm or ranch), regional and national scales. GRACEnet's geographical extent, use of common procedures, and cooperation with other North American C cycle research programs will result in robust information to promote scientifically based conservation technologies that are relevant to national and international policy makers, as well as to agricultural producers and practitioners.

As part of a research effort called GRACEnet (Greenhouse Gas Reduction through Agricultural Carbon Enhancement Network), this paper summarizes available information concerning management effects on soil organic carbon (SOC) and carbon dioxide (CO sub(2)), nitrous oxide (N sub(2)O), and methane (CH sub(4)) fluxes in cropland and rangeland in northwestern USA and western Canada, a region characterized by its inherently productive soils and highly variable climate. Continuous cropping under no-tillage in the region increased SOC by 0.27 plus or minus 0.19 Mg C ha super(-1) yr super(-1), which is similar to the Intergovernmental Panel on Climate Change (IPCC) estimate for net annual change in C stocks from improved cropland management. Soil organic C sequestration potential for rangelands was highly variable due to the diversity of plant communities, soils, and landscapes, underscoring the need for additional long-term C cycling research on rangeland. Despite high variability, grazing increased SOC by 0.16 plus or minus 0.12 Mg C ha super(-1) yr super(-1) and converting cropland or reclaimed mineland to grass increased SOC by 0.94 plus or minus 0.86 Mg C ha super(-1) yr super(-1). Although there was generally poor geographical coverage throughout the region with respect to estimates of N sub(2)O and CH sub(4) flux, emission of N sub(2)O was greatest in irrigated cropland, followed by non-irrigated cropland, and rangeland. Rangeland and non-irrigated cropland appeared to be a sink for atmospheric CH sub(4), but the size of this sink was difficult to determine given the few studies conducted. Researchers in the region are challenged to fill the large voids of knowledge regarding CO sub(2), N sub(2)O, and CH sub(4) flux from cropland and rangeland in the northwestern USA and western Canada, as well as integrate such data to determine the net effect of agricultural management on radiative forcing of the atmosphere.

The organism can occur as a commensally in the naso-pharyngeal region of apparently healthy animals and it can be a primary or secondary pathogen in the disease process of birds. The complete genome of an avian strain of P. multocida has been sequenced and was shown to possess two filamentous hemagglutinin genes designated fhaB1 and fhaB2. Filamentous hemagglutinin transposon mutants of a bovine strain of P. multocida are attenuated in mice. Here, we report the construction of an fhaB2 P. multocida mutant in an avian strain P-1059 (A:3). The fhaB2 mutant and the parent were assessed for virulence in turkeys by intranasal and intravenous challenge. Inactivation of fhaB2 resulted in a high degree of attenuation when turkeys were challenged intranasally and to a lesser degree when intravenously administered. Resistance of the fhaB2 mutant and parent strain to killing by serum complement was similar.

Typing by amplified fragment length polymorphism (AFLP) resulted in observation of 10 profiles that differed by one to six bands. Salmonella strains were screened for presence of phage genes using a PCR-phage typing; five genes from P22 phage and genes encoding putative virulence factors from phages Gifsy-1, Gifsy-2 and Fels-1 were selected for testing. This set of genes was sufficient for dividing the strains into eight different PCR-phage profiles. Similar grouping of strains was observed in case of all the employed DNA techniques and they corresponded well with the phage type and antimicrobial resistance of the strains. The highest discriminating power was achieved with use of the AFLP, yet the detection of integrons and PCR-phage typing also proved to be valuable in typing the S. Typhimurium strains.

The Riparian Ecosystem Management Model (REMM) was developed as process-based model to evaluate the fate of nutrients and sediment through a riparian buffer up to the edge of a stream. A one-at-a-time sensitivity analysis was performed on REMM to evaluate the effects that changing herbaceous buffer scenarios have on N, P, and sediment in surface and ground water. Vegetation characteristics such as rooting depth, LAI, and plant height, along with some physical buffer characteristics were varied within their "typical" range and compared to a "base case" scenario. Model outputs were not sensitive to plant height or LAI, but moderately sensitive to changes in SLA. Model outputs were only sensitive to rooting depth as roots became shallower in the soil profile. Sediment yield and dissolved nitrate in surface water were the most sensitive to changes in Manning's n, while other soil physical characteristics such as surface roughness, surface condition, and % bare soil had little to no effect on model outcomes. Dissolved surface nitrate, organic P, and dissolved subsurface nitrate were all moderately sensitive to changes in saturated hydraulic conductivity and the slope of the buffer. Results indicate that within the model, many vegetation characteristics do not directly play a role in the physical transport of nutrients and sediment in surface and subsurface water; therefore, utilizing REMM to evaluate effects of specific herbaceous plant types may have limited value unless specific leaf area or rooting depth are considered. It would be possible to model and perhaps achieve specific load reductions by modifying slope and other physical characteristics or by considering forest versus grass buffers.

We evaluated the effectiveness of polymer flocculants to improve drainage and filtration performance of sand filter beds by increasing the particle size of manure. A pilot separation unit was evaluated at the Swine Unit of the NCSU Lake Wheeler Road Laboratory in Raleigh, North Carolina, in 40 consecutive cycles during a 20-month period. The unit consisted of a homogenization tank that mixed the flushed swine manure, an in-line polymer mixer, and two sand filter beds (29.7 m super(2)) designed to receive 30.5 cm (1 ft) depth of the polymer-treated effluent. Flocculation treatment using polyacrylamide (PAM) polymer improved drainage characteristics of the sand filter by preventing clogging and surface sealing. The combination of flocculation and filtration treatment removed 97% of total suspended solids (TSS) and volatile suspended solids (VSS), 85% of biochemical oxygen demand (BOD sub(5)), and 83% of chemical oxygen demand (COD) from the flushed manure. Along with the solids, treatment resulted in capture of 61% total Kjeldahl nitrogen (TKN) and 72% total phosphorus (TP). Most of the nutrients removed in the solids were organic forms. Drying time to produce removable cakes varied significantly with the loading rate of solids applied to the sand filter bed. A load of <2 kg TSS m super(-2) per drying cycle allowed completion of the drying cycle in about 8 days, which is desirable to reduce potential fly problems. Our results indicate that PAM flocculation enhances performance of dewatering sand filter beds for swine manure applications.

AN - 17213602; 6928754 AB - Bacterial canker of citrus is a serious disease of citrus worldwide. Five forms of the disease have been described, cankers "u, "B", "C", "D", and "E". Although considerable genetic diversity has been described among the causal agents of the five forms of citrus canker and supports multiple taxons, the causal agents currently are classified as pathovars citri ("u), aurantifolii ("B/C/D") and citrumelo ("E") of a single species, Xanthomonas campestris pv. citri (or X. axonopodis pv. citri). To determine the taxonomic relatedness among strains of X. campestris pv. citri, we conducted DNA-DNA relatedness assays, sequenced the 16S-23S intergenic spacer (ITS) regions, and performed amplified fragment length polymorphism (AFLP) analysis, using 44 strains representative of the five recognized forms of citrus canker. Under stringent DNA reassociation conditions (T sub(m)-15 degree C), three distinct genotypes of citrus pathogens were revealed: taxon I included all "u strains; taxon II contained all "B", "C", and "D" strains; and taxon III contained all "E" strains. The three citrus taxa showed less than 50% (mean) DNA-DNA relatedness to each other and less than 30% (mean) to X. campestris pv. campestris and X. axonopodis pv. axonopodis. Taxa I and II strains share over 70% DNA relatedness to X. campestris pv. malvacearum and X. campestris pv. phaseoli var. fuscans, respectively (at T sub(m)-15 degree C). Taxon III strains share 70% relatedness to X. campestris pv. alfalfae. Previous and present phenotypic data support these DNA reassociation data. Taxon II strains grow more slowly on agar media than taxa I an IIID strains. Taxa I an IIID strains utilize maltose, and liquefy gelatin whereas taxon II strains do not. Taxon I strains hydrolyze pectate (pH 7.0) whereas Taxon II strains do not. Taxon III strains utilize raffinose whereas Taxon I strains do not. Each taxon can be differentiated by serology and pathogenicity. We propose taxa I II, an IIID citrus strains be named, respectively, Xanthomonas smithii subsp. citri (ex Hasse, 1915) sp. nov. nom. rev. comb. nov., Xanthomonas fuscans subsp. aurantifolii (ex Gabriel et al., 1989) sp. nov. nom. rev. comb. nov., and Xanthomonas alfalfae subsp. citrumelo (ex Riker and Jones) Gabriel et al., 1989 nov. rev. comb. nov. Furthermore, based on the analysis of 40 strains of 19 other xanthomonads, we propose to reclassify X. campestris pv. malvacearum (ex Smith, 1901) Dye 1978 as X. smithii subsp. smithii sp. nov. comb. nov. nom. nov.; X. campestris pv. alfalfae (ex Riker and Jones) Dye 1978 as X. alfalfae subsp. alfalfae (ex Riker et al., 1935) sp. nov. nov. rev.; and "var. fuscans" (ex Burkholder 1930) of X. campestris pv. phaseoli (ex Smith, 1897) as X. fuscans subsp. fuscans sp. nov.

Previous studies of herbivore impacts in plant communities have focused on tree species and ignored the herbaceous community. In an experiment in mature-phase, tropical moist forest sites in central Panama, we studied the impact of excluding ground-dwelling mammals on the richness and abundance of herbs in 16, 30 x 45-m plots. Within each plot, we censused the herbaceous community in 28, 2 x 2-m subplots (1,792 m super(2) total area sampled). We identified over 54 species of herbs averaging 1.21 ramets m super(-2) and covering approximately 4.25% of the forest floor. Excluding mammals for 5 years had no impact on overall species richness. Within exclosures, however, there was a significant two-fold increase in the density of rare species. Overall herbaceous density and percent cover did not differ between exclosures and adjacent control plots, although cover did increase over time. Mammalian exclusion significantly increased the total cover of three-dominant herb species, Pharus latifolius, Calathea inocephala, and Adiantum lucidum, but did not affect their density. This study represents one of the most extensive herbaceous community censuses conducted in tropical forests and is among a few that quantify herbaceous distribution and abundance in terms of both density and cover. Additionally, this work represents the first community level test of mammalian impacts on the herbaceous community in a tropical forest to date. Our results suggest that ground dwelling mammals do not play a key role in altering the relative abundance patterns of tropical herbs in the short term. Furthermore, our results contrast sharply with prior studies on similar temporal and spatial scales that demonstrate mammals strongly alter tree seedling composition and reduce seedling density. Thus, we question the pervasiveness of top-down control on tropical plant communities and the paradigm that defaunation will inexorably lead to widespread, catastrophic shifts in plant communities.

Seven hundred and sixty-nine fragments from 50 to 900 bp in length were amplified in 10 PCR reactions using 10 fixed primers in combination with four fluorescent labeled arbitrary primers. Three hundred and eighty-eight of these fragments were polymorphic among the 59 Lactuca entries and 107 fragments were polymorphic among the 53 lettuce cultivars and the six wild accessions; 251 fragments were present only in the wild species. These markers not only discriminated all cultivars, but also revealed the evolutionary relationship among the three species: L. sativa, the cultivated species, is more closely related to L. serriola than to L. saligna. Cluster analysis grouped the cultivars by horticultural types with a few exceptions. These results are consistent with previous findings using RFLP, AFLP, and SAMPL markers. The TRAP markers revealed significant differences in genetic variability among horticultural types, measured by the average genetic similarity among the cultivars of the same type. Within the sample set, the leaf type and butterhead types possessed relatively high genetic variability, the iceberg types had moderate variability and the romaine types had the lowest variability. The genetic behavior of TRAP markers was assessed with a mapping population of 45 recombinant inbred lines (RILs) derived from an interspecific cross between L. serriola and L. sativa. Almost all the markers segregated in the expected 1:1 Mendelian ratio and are being incorporated into the existing lettuce linkage maps. Our results indicate that the TRAP markers can provide a powerful technique for fingerprinting lettuce cultivars.

This research was conducted to improve the methodology for quantifying hydroxamic acids and to determine the relationship between hydroxamic acid content and phytotoxicity of extracts of rye root and shoot tissue harvested at selected growth stages. Detection limits for an LC/MS-MS method for analysis of hydroxamic acids from crude aqueous extracts were better than have been reported previously. (2R)-2- beta -d-Glucopyranosyloxy-4-hydroxy-(2H)-1,4-be nzoxazin-3(4H)-one (DIBOA-G), 2,4-dihydroxy-(2H)-1,4-benzoxazin-3(4H)-one (DIBOA), benzoxazolin-2(3H)-one (BOA), and the methoxy-substituted form of these compounds, (2R)-2- beta -d-glucopyranosyloxy-4-hydroxy-7-methoxy-(2 H)-1,4-benzoxazin-3(4H)-one (DIMBOA glucose), 2,4-hydroxy-7-methoxy-(2H)-1,4-benzoxazin-3(4H)-one (DIMBOA), and 6-methoxy-benzoxazolin-2(3H)-one (MBOA), were all detected in rye tissue. DIBOA and BOA were prevalent in shoot tissue, whereas the methoxy-substituted compounds, DIMBOA glucose and MBOA, were prevalent in root tissue. Total hydroxamic acid concentration in rye tissue generally declined with age. Aqueous crude extracts of rye shoot tissue were more toxic than extracts of root tissue to lettuce (Lactuca sativa L.) and tomato (Lycopersicon esculentum Mill.) root length. Extracts of rye seedlings (Feekes growth stage 2) were most phytotoxic, but there was no pattern to the phytotoxicity of extracts of rye sampled at growth stages 4 to 10.5.4, and no correlation of hydroxamic acid content and phytotoxicity (I sub(50) values). Analysis of dose-response model slope coefficients indicated a lack of parallelism among models for rye extracts from different growth stages, suggesting that phytotoxicity may be attributed to compounds with different modes of action at different stages. Hydroxamic acids may account for the phytoxicity of extracts derived from rye at early growth stages, but other compounds are probably responsible in later growth stages.

The parasite appears to infect in many fishes from Hawaii, Florida, Texas, and Utah. The gill trematode has a complex life cycle involving definitive hosts (aquatic birds and occasionally some mammals) and intermediate hosts (aquatic snails and several fish species). In the United States, the green heron (Butorides virescens) and the great egret (Ardea alba) serve as definitive hosts. The first intermediate host, the red-rim melania (Melanoides tubercu-latus), an exotic snail, has been found in 15 southern and western states. This snail exhibits resistance to desiccation, molluscicides, and disinfectants and has been documented to out-compete established mollusks. Both the gill trematode and its exotic snail host continue to spread in the United States. JF - Fisheries AU - Mitchell, A J AU - Overstreet, R M AU - Goodwin, A E AU - Brandt, T M AD - Harry K.

The objective of this study was to evaluate the potential impacts of projected climate changes during 2070-2099 under three emissions scenarios (A2a, and B2a, and GGa1) on hydrology, soil loss, and crop production in Changwu tableland region on southern Loess Plateau of China. Monthly projections for the periods of 1950-1999 and 2070-2099 were used from the Hadley Centre's general circulation model (HadCM3). A stochastic weather generator (CLIGEN) was used to downscale monthly HadCM3 projections to daily values at three spatial scales. The Water Erosion Prediction Project (WEPP) model was run for a wheat-wheat-maize rotation under conventional and conservation tillage at the 8.7% and 17.6% slopes. HadCM3 predicted a 23-37% increase in annual precipitation, 2.3-4.3 degree C rise in maximum temperature, and 3.6-5.3 degree C rise in minimum temperature for the region over the century. Compared with the present climate, predicted percent increases under climate changes, as averaged over the three spatial scales for each emissions scenario and slope, ranged from 29 to 79% for runoff, 2 to 81% for soil loss, 15 to 44% for wheat grain yield, 40 to 58% for maize yield, 25 to 28% for crop transpiration, 21 to 34% for soil evaporation, and 4 to 12% for long-term soil water reserve under the conventional tillage. However, adoption of the conservation (delayed) tillage could reduce runoff by 18-38%, and decrease soil loss by 56-68% as compared to the conventional tillage under the present climate. These results suggest that the use of the conservation tillage would be sufficient to maintain low runoff and erosion levels and thus protect agro- ecosystems under projected climate changes.

Fish were fed a 32% protein commercial diet supplemented with 0, 50, 100 and 200 mg beta -glucan for 14 weeks. After 10 weeks of feeding, neither immunization, beta -glucan nor their interaction affected weight gain and survival. Feed efficiency ratio (FER) of fish fed the 100 and 200-mg beta -glucan diets was slightly but significantly lower than those of the group fed the 50-mg beta -glucan diet, but these values did not differ from that of the control (0 mg beta -glucan diet). Average percent mortality (PM) decreased and relative percent survival (RPS) increased in fish immunized with the S. iniae ARS-98-60 vaccine. Dietary levels of beta -glucan and the interaction between dietary levels of beta -glucan and immunization had no effect on PM and RPS. Serum lysozyme activity at 14 days post-challenge (PC) significantly decreased in fish fed the highest dietary beta -glucan level but was not affected by immunization and the interaction between beta -glucan and immunization. Specific antibody levels 21 days post-booster immunization (PBI) and 14 days PC were not affected by dietary beta -glucan and the interaction between beta -glucan and immunization These parameters, however, were significantly enhanced by immunization with S. iniae vaccine, leading to increase protection against S. iniae infection. Dietary levels of beta -glucan had no effect on stimulating the S. iniae-specific antibody response and resistance of Nile tilapia against S. iniae infection.

AN - 68056876; 16029012 AB - Methods were devised for the isolation of large amounts of pure alpha-chaconine and alpha-solanine from Dejima potatoes and for the extraction and analysis of total glycoalkaloids from five fresh potato varieties (Dejima, Jowon, Sumi, Toya, and Vora Valley). These compounds were then evaluated in experiments using a tetrazolium microculture (MTT) assay to assess the anticarcinogenic effects of (a) the isolated pure glycoalkaloids separately, (b) artificial mixtures of the two glycoalkaloids, and (c) the total glycoalkaloids isolated from each of the five potato varieties. All samples tested reduced the numbers of the following human cell lines: cervical (HeLa), liver (HepG2), lymphoma (U937), stomach (AGS and KATO III) cancer cells and normal liver (Chang) cells. The results show that (a) the effects of the glycoalkaloids were concentration dependent in the range of 0.1-10 mug/mL (0.117-11.7 nmol/mL); (b) alpha-chaconine was more active than was alpha-solanine; (c) some mixtures exhibited synergistic effects, whereas other produced additive ones; (d) the different cancer cells varied in their susceptibilities to destruction; and (e) the destruction of normal liver cells was generally lower than that of cancer liver cells. The decreases in cell populations were also observed visually by reversed-phase microscopy. The results complement related observations on the anticarcinogenic potential of food ingredients.

AN - 68056833; 16028979 AB - Essential oil extracts from Callicarpa americana and Callicarpa japonica were investigated. Bioassay-guided fractionation of C. americana extracts using the yellow fever mosquito, Aedes aegypti, led to the isolation of alpha-humulene, humulene epoxide II, and intermedeol and a newly isolated terpenoid (callicarpenal). Similar work involving C. japonica resulted in the isolation of an additional compound, spathulenol, as well as the four compounds isolated from C. americana. Structure elucidation was performed on all isolated compounds using a combination of gas chromatography-mass spectrometry-electron ionization, high-resolution liquid chromatography-MS-electrospray ionization, and one- and two-dimensional NMR experiments. Heretofore, 13,14,15,16-tetranorclerodane, callicarpenal, has never been identified from natural sources. Complete (1)H and (13)C NMR assignment data are provided for this compound. In bite deterrent studies, spathulenol, intermedeol, and callicarpenal showed significant repellent activity against A. aegypti and Anopheles stephensi.

About 1572 moth species have been found to use 377 pheromone components, the majority being alcohols, aldehydes or acetate esters of olefinic chains of 10-22 carbons. Since there are limited numbers of possible unsaturated (double bonded) E- and Z-configured isomers of these chains, there may be constraints on incipient species evolving new pheromone components, especially if they are utilized by existing species. Here I develop algorithms that count and name all possible structures of chains with or without a functional group. The results show that for acetate esters there are only seven or nine monounsaturated isomers of six or seven carbon chains, respectively, suggesting use of these compounds could limit the number of communication channels available for radiation of new species (no moths use these short chains). For commonly used 14-carbon chains with an acetate ester functional group, and 1-3 unsaturations, there are 1039 isomers. A total of 2,096,883 isomers were counted from all multiply unsaturated 10-22-carbon chain acetate esters. The number of possible signals quickly extends into millions when considering pheromone blends of 2-4 components used by most species. There should be little chemical constraint on evolution of new communication channels based on compounds of 10 or more carbons, even for closely related species (e.g. ermine moths, Yponomeuta).

Where should the emphasis be? AN - 68059399; 16030280 AB - The consumption of adequate levels and proper balance of essential nutrients is critical for maintaining health. The identification, isolation, and purification of nutrients in the early 20th century raised the possibility that optimal health outcomes could be realized through nutrient supplementation. Recent attempts using this approach for cardiovascular disease and lung cancer have been disappointing, as demonstrated with vitamin E and beta carotene. Moreover, previously unrecognized risks caused by nutrient toxicity and nutrient interactions have surfaced during intervention studies. The most promising data in the area of nutrition and positive health outcomes relate to dietary patterns, not nutrient supplements. These data suggest that other factors in food or the relative presence of some foods and the absence of other foods are more important than the level of individual nutrients consumed. Finally, unknown are the implications on public health behavior of shifting the emphasis away from food toward nutrient supplements. Notwithstanding the justification for targeting recommendations for nutrient supplements to certain segments of the population (eg, the elderly), there are insufficient data to justify an alteration in public health policy from one that emphasizes food and diet to one that emphasizes nutrient supplements.

Many of these polymorphisms can be detected using hybridization probes derived from insertion sequences; an observation that suggests these IS elements are active and can transpose in L. interrogans. Two spontaneous mutants of L. interrogans serovar Pomona strain RZ11 were isolated by immune selection and characterized. Changes in the size and antigenicity of LPS from these mutants were detected. Genetic analysis showed that both mutants have additional copies of an IS3-like element, designated IS1501, that are not present in the parental strain. One mutant, GT211, has a single additional copy of IS1501, whereas the other mutant, GT210 has three additional copies of IS1501 relative to strain RZ11. IS1501 transposition generated 3-bp direct repeats from target sequences flanking the insertion site. RT-PCR analysis of transcripts at altered loci showed IS1501 transcripts extended into adjacent sequences. These data are the first to show spontaneous transposition of an endogenous Leptospira insertion sequence, and suggest that IS1501 may be capable of gene activation.

Field-scale pesticide volatilization involves the interaction of a number of complex variables. There is a need to acquire pesticide volatilization fluxes from a location where several of these variables can be held constant. Accordingly, soil properties, tillage practices, surface residue management, and pesticide formulations were held constant while fundamental information regarding metolachlor volatilization (a pre-emergent pesticide) was monitored over a five-year period as influenced by meteorological variables and soil water content. Metolachlor vapor concentrations were measured continuously for 120 h after each application using polyurethane foam plugs in a logarithmic profile above the soil surface. A flux gradient technique was used to compute volatilization fluxes from metolachlor concentration profiles and turbulent fluxes of heat and water vapor (as determined from eddy covariance measurements). Differences in meteorological conditions and surface soil water contents resulted in variability of the volatilization losses over the years studied. The peak volatilization losses for each year occurred during the first 24 h after application with a maximum flux rate in 2001 (1500 ng m super(-2) s super(-1)) associated with wet surface soil conditions combined with warm temperatures. The cumulative volatilization losses for the 120-hour period following metolachlor application varied over the years from 5 to 25% of the applied active ingredient, with approximately 87% of the losses occurring during the first 72 h. In all of the years studied, volatilization occurred diurnally and accounted for between 43 and 86% during the day and 14 and 57% during the night of the total measured loss. The results suggest that metolachlor volatilization is influenced by multiple factors involving meteorological, surface soil, and chemical factors.

AN - 68002144; 15998115 AB - Experiments were conducted to determine the association between resistance to grain mold and the accumulations of chitinase and sormatin. Eight sorghum lines were treated at 50% bloom with Fusarium thapsinum, Curvularia lunata, a mixture of the two fungi, and a water-sprayed control. At maturity, percent disease severity, seed germination rates, and kernel weight were recorded. Chitinase and sormatin content (mg/g of dry weight) were measured in seed samples taken at 30 and 50 days after treatment (DAT). Seed chitinase content was moderately affected by sorghum line (P = 0.10) and significantly affected by the developmental stage of the kernels (P = 0.05). Cultivars Sureno, 98LB650, and 98LB723 exhibited larger negative changes in chitinase content at 50 DAT over water-sprayed control treatment at 30 DAT than the susceptible cultivars Dorado, RTx2536, and RTx430. In 2000, significant negative correlations were observed for percent disease severity and chitinase content at 30 DAT, seed germination and sormatin content at 50 DAT, and between seed germination and kernel weight. There also was a significant positive correlation between germination and chitinase content at 30 DAT. No association between disease severity and changes in chitinase content at 50 DAT was observed. Sormatin content also was significantly affected by the stage of kernel development. Sorghum cultivars inoculated with fungal pathogens responded differently as indicated by the significant sorghum line x treatment interaction for sormatin content in 2000. In both years, larger increases in sormatin content over the water-sprayed control treatments were observed on moderately susceptible to susceptible cultivars such as 98LB650, 98LB723, 98LB789, RTx430, and RTx2536 than on Sureno. Except for percent disease severity and germination, there was no significant association among all of the other parameters measured in 2001. The results of this study did not clearly demonstrate a strong association between resistance to grain mold and the accumulation of sormatin and chitinase. Thus, there is the possibility that certain moderately resistant to resistant sorghum cultivars, such as Sureno, may employ other strategies to eschew or restrict fungal invasion either before or after physiological maturity.

13634738 AB - The retention and movement of water and atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) was investigated in a calcareous soil (Krome) amended with three types of compost: (1) Clean organic waste (COW)- municipal solid waste cleaned of plastic materials and metal containers, (2) Biosolids (BSD)- sludge from municipal waste and (3) Bedminster (BDM)--a mixture containing 75% COW and 25% BSD. The research was conducted in two phases; a column-leaching study (dynamic) and a batch-equilibrium method (static). The column study demonstrated that while applying simulated rain, atrazine, leached out at a slower rate by 41, 24, and 18% from soil amended with BDM, BSD, and COW composts, respectively, during the first simulated storm event. BDM application resulted in lowest water movement and atrazine-leaching rate compared to the other composts tested. This study suggests that adding 134 t ha super(-1) of compost to the calcareous soil increased soil water holding capacity, reduced water movement and increased atrazine detention and reduced leaching potential of atrazine thereby reducing the potential for groundwater pollution. This study further demonstrates that soil amendment (particularly BDM) is effective in reducing the leaching potential of atrazine at the low rainfall amounts (corresponding to 0.5 pore volume). However, such amendment may not be effective in preventing leaching under more intense rain conditions or multiple rainfall events (corresponding to 3 or more pore volumes).

Preplant N applications compared with a split application and the effects on yield, yield components, and mycotoxin levels were also examined. Experiments were conducted at Site WR (102-cm-wide rows, Beulah fine sandy loam) and Site NR (76-cm-wide rows, Dundee silty clay). Plant densities of 71760, 82160, 92560, and 102960 plants ha super(-1) were grown in eight-row plots, 9.1 m long at both sites. The N fertility treatments were 112 kg N ha super(-1) preplant, 224 kg N ha super(-1) preplant, and 112 kg N ha super(-1) preplant + 112 kg N ha super(-1) sidedressed at V6 (six leaves). Yields at Site WR did not differ among populations. Maximum yields at Site NR were at 71760 plants ha super(-1) (10.3 Mg ha super(-1)) and then declined (b = -0.5065). Kernels per ear declined (b = -40.09 and b = -42.69), kernel weights declined (b = -0.4328 and b = -0.8172), and stalk lodging increased (b = 0.0103 and b = 0.0251) with increased populations for Sites WR and NR, respectively. These and previous data place the maximum population for corn in the Midsouth at about 70000 plants ha super(-1). No differences in yield occurred between the 224 kg N ha super(-1) preplant treatment and the split application of N. Yields were generally less with 112 kg N ha super(-1) per-plant only. Aflatoxin and fumonisin levels at both sites were unaffected by plant population of N fertility. JF - Agronomy Journal AU - Bruns, HArnold AU - Abbas, H K AD - USDA-ARS, Crop Genetics and Prod. Res.

AN - 68681544; 16222793 AB - The seeds of two Apiaceae species, Ligusticum hultenii and Lomatium californicum, were investigated. Preliminary bioassays indicated that methylene chloride extracts of seeds of both species contained selective phytotoxic activity against monocots and antifungal activity against Colletotrichum fragariae. Active constituents were isolated by bioassay-guided fractionation, and the structures were elucidated by NMR and GC-MS as apiol and Z-ligustilide, isolated from L. hultenii and L. californicum, respectively. Apiol and Z-ligustilide had I50 values of about 80 and 600 microM, respectively, for inhibition of the growth of Lemna paucicostata. The methylene chloride (CH2Cl2) extracts of the seeds and the isolated and purified compounds were tested against the 2-methylisobomeol-producing cyanobacterium (blue-green alga) Oscillatoria perornata, and the green alga Selenastrum capricornutum. The CH2Cl2 extracts of both Apiaceae species and apiol were weakly toxic to both species of phytoplankton, while Z-ligustilide was toxic to both with a lowest complete inhibitory concentration (LCIC) of 53 microM. Seeds of L. californicum and L. hultenii were found to be rich sources of Z-ligustilide (97 mg/g of dry seed) and apiol (40 mg/g of dry seed), respectively.

AN - 68570164; 16152936 AB - An efficient multiresidue method for analysis of fluoroquinolones in shrimp has been developed in which quantitation by fluorescence and confirmation by Multiple Stage Mass Spectrometry (MS) is achieved simultaneously. In this method, shrimp tissue is extracted with ammoniacal acetonitrile and the extract is defatted and then evaporated. After dissolution in basic phosphate buffer, fluoroquinolones in the extract are separated by liquid chromatography and quantitated, taking advantage of their intense fluorescence. Eluate from the fluorescence detector enters the MS, which allows for confirmation by monitoring ratios of 2 prominent product ions in the MS3 or MS2 spectrum. Using this method, 8 fluoroquinolones have been analyzed in shrimp samples fortified at 10, 25, 50, or 100 ppb levels. Recoveries for desethyleneciprofloxacin, norfloxacin, ciprofloxacin, danofloxacin, enrofloxacin, orbifloxacin, sarafloxacin, and difloxacin ranged from 75 to 92%, with relative standard deviation values of <6%.

AN - 68514580; 16119554 AB - Recently, catnip, Nepeta cataria L. (Lamiaceae), essential oil has been formulated and marketed as an alternative repellent for protection against biting arthropods by several vendors. We isolated the major active components of catnip oil, E,Z- and Z,E-nepetalactone, and quantitatively measured their antibiting efficacy compared with the repellents N,N-diethyl-3-methylbenzamide (deet) and chiral (1S,2'S)-2-methylpiperidinyl-3-cyclohexene-1-carboxamide (SS220) against the yellowfever mosquito, Aedes aegypti (L.), by using an in vitro assay and human volunteers at 24 nmol compound/cm2 (cloth or skin). Of all compounds tested in an in vitro assay, SS220 ranked as the most effective, whereas catnip oil and the nepetalactone compounds did not differ significantly from each other or from deet. However, in human volunteer bioassays, neither E,Z and Z,E-nepetalactone nor racemic nepetalactone deterred mosquito biting as effectively as SS220 or deet. All compounds differed significantly from the control. We conclude that catnip oil and nepetalactone isomers are significantly less effective than deet or SS220 in deterring the biting of Ae. aegypti.

AN - 68029916; 16013376 AB - The hides of cattle are the primary source of pathogens such as Escherichia coli O157:H7 that contaminate preevisceration carcasses during commercial beef processing. A number of interventions that reduce hide contamination and subsequent carcass contamination are currently being developed. The objective of this study was to determine the efficacy of ozonated and electrolyzed oxidizing (EO) waters to decontaminate beef hides and to compare these treatments with similar washing in water without the active antimicrobial compounds. Cattle hides draped over barrels were used as the model system. Ozonated water (2 ppm) was applied at 4,800 kPa (700 lb in2) and 15 degrees C for 10 s. Alkaline EO water and acidic EO water were sequentially applied at 60 degrees C for 10 s at 4,800 and 1,700 kPa (250 lb in2), respectively. Treatment using ozonated water reduced hide aerobic plate counts by 2.1 log CFU/100 cm2 and reduced Enterobacteriaceae counts by 3.4 log CFU/100 cm2. EO water treatment reduced aerobic plate counts by 3.5 log CFU/100 cm2 and reduced Enterobacteriaceae counts by 4.3 log CFU/100 cm2. Water controls that matched the wash conditions of the ozonated and EO treatments reduced aerobic plate counts by only 0.5 and 1.0 log CFU/100 cm2, respectively, and each reduced Enterobacteriaceae counts by 0.9 log CFU/100 cm2. The prevalence of E. coli O157 on hides was reduced from 89 to 31% following treatment with ozonated water and from 82 to 35% following EO water treatment. Control wash treatments had no significant effect on the prevalence of E. coli O157:H7. These results demonstrate that ozonated and EO waters can be used to decontaminate hides during processing and may be viable treatments for significantly reducing pathogen loads on beef hides, thereby reducing pathogens on beef carcasses.

AN - 68028627; 16013400 AB - After harvest, maize is dried artificially to halt fungal growth and mycotoxin production while in postharvest storage. The process often limits harvest capacity and has been a frequent cause of seed injury. Higher drying temperatures could lead to shorter drying periods and faster turnover; however, there is often a deterioration of the physical grain quality, including increased breakage susceptibility and loss of viability. The goals of this study were to determine the effect of different postharvest drying temperatures on Aspergillus filavus and Fusarium verticillioides survival and aflatoxin content in maize and to determine the viability of the seed. Five corn hybrids varying in resistance to A. flavus were side needle-inoculated with A. flavus, harvested at physiological maturity, and dried at temperatures ranging from 40 to 70 degrees C. Kernels were evaluated for aflatoxin, stress cracks, germination, and kernel infection by A. flavus and a natural infestation of F. verticillioides. Drying temperature had no effects on aflatoxin concentration given the heat stability of the toxin. With increased temperatures from 40 to 70 degrees C, germination decreased significantly, from 96 to 27%, and stress cracks increased significantly (1.4 up to 18.7). At temperatures above 60 degrees C, F. verticillioides kernel infection was significantly reduced to less than 18%. At 70 degrees C, there was a significant reduction in A. flavus kernel infection, from 11 to 3%. This information is useful in determining a range of temperatures that can be used for drying seed when fungal infection, stress cracks, and seed viability are of interest.

AN - 68028252; 16013368 AB - The effect of prechill fecal contamination on numbers of bacteria on immersion-chilled carcasses was tested in each of three replicate trials. For each trial, 16 eviscerated broiler carcasses were split into 32 halves and assigned to one of two groups. Cecal contents (0.1 g inoculated with Campylobacter and nalidixic acid-resistant Salmonella) were applied to each of eight halves in one group (direct contamination) that were placed into one paddle chiller (contaminated), whereas the other paired halves were placed into another chiller (control). From the second group of eight split birds, one of each paired half was placed in the contaminated chiller (to determine cross-contamination) and the other half was placed in the control chiller. Postchill carcass halves were sampled by a 1-min rinse in sterile water, which was collected and cultured. Bacterial counts were reported as log CFU per milliliter of rinsate. There were no significant statistical differences (paired t test, P < 0.05) from direct contamination for coliforms (mean 3.0 log CFU) and Escherichia coli (mean 2.7 log CFU), although Campylobacter numbers significantly increased from control values because of direct contamination (1.5 versus 2.1 log CFU), and the incidence increased from 79 to 100%. There was no significant effect of cross-contamination on coliform (mean 2.9 log CFU) or E. coli (mean 2.6 log CFU) numbers. Nevertheless, Campylobacter levels were significantly higher after exposure to cross-contamination (1.6 versus 2.0 log CFU), and the incidence of this bacterium increased from 75 to 100%. Salmonella-positive halves increased from 0 to 42% postchill because of direct contamination and from 0 to 25% as a result of cross-contamination after chilling. Water samples and surface swabs taken postchill from the contaminated chiller were higher for Campylobacter than those taken from the control chiller. Immersion chilling equilibrated bacterial numbers between contaminated and control halves subjected to either direct contamination or cross-contamination for coliforms and E. coli. Campylobacter numbers, Campylobacter incidence, and Salmonella incidence increased because of both direct contamination and cross-contamination in the chiller. Postchill E. coli numbers did not indicate which carcass halves were contaminated with feces before chilling.

AN - 68009350; 16000757 AB - We describe a simple colony overlay procedure for peptidases (COPP) for the rapid fluorogenic detection and quantification of Vibrionaceae from seawater, shellfish, sewage, and clinical samples. The assay detects phosphoglucose isomerase with a lysyl aminopeptidase activity that is produced by Vibrionaceae family members. Overnight cultures are overlaid for 10 min with membranes containing a synthetic substrate, and the membranes are examined for fluorescent foci under UV illumination. Fluorescent foci were produced by all the Vibrionaceae tested, including Vibrio spp., Aeromonas spp., and Plesiomonas spp. Fluorescence was not produced by non-Vibrionaceae pathogens. Vibrio cholerae strains O1, O139, O22, and O155 were strongly positive. Seawater and oysters were assayed, and 87 of 93 (93.5%) of the positive isolates were identified biochemically as Vibrionaceae, principally Vibrio vulnificus, Vibrio parahaemolyticus, Aeromonas hydrophila, Photobacterium damselae, and Shewanella putrefaciens. None of 50 nonfluorescent isolates were Vibrionaceae. No Vibrionaceae were detected in soil, and only A. hydrophila was detected in sewage. The COPP technique may be particularly valuable in environmental and food-testing laboratories and for monitoring water quality in the aquaculture industry.

AN - 68007547; 15998864 AB - Received for publication December 22, 2004. Research was initiated to study the interaction between soil amendments (lime, gypsum, and ferrous sulfate) and dissolved molybdate reactive phosphorus [RP(<0.45)] losses from manure applications from concentrated runoff flow through a sod surface. Four run-over boxes (2.2-m2 surface area) were prepared for each treatment with a bermudagrass [Cynodon dactylon (L.) Pers.] sod surface (using sod blocks) and composted dairy manure was surface-applied at rates of 0, 4.5, 9, or 13.5 Mg ha-1. The three soil amendments were then applied to the boxes. Two 30-min runoff events were conducted and runoff water was collected at 10-min intervals and analyzed for RP(<0.45). Results indicated that the addition of ferrous sulfate was very effective at reducing the level of RP(<0.45). in runoff water, reducing RP(<0.45) from 1.3 mg L(-1) for the highest compost rate with no amendment to 0.2 mg L(-1) for the ferrous sulfate in the first 10 min of runoff. Lime and gypsum showed a small impact on reducing RP(<0.45), with a reduction in the first 10 min to 0.9 and 0.8 mg L(-1), respectively. The ferrous sulfate reduced the RP(<0.45) in the tank at the end of the first runoff event by 66.3% compared with no amendment. In the second runoff event, the ferrous sulfate was very effective at reducing RP(<0.45) in runoff, with no significant differences in RP(<0.45) with application of 13.5 Mg ha(-1) compost compared with no manure application. The results indicate that the addition of ferrous sulfate may greatly reduce RP(<0.45) losses in runoff and has considerable potential to be used on pasture, turfgrass, and filter strips to reduce the initial RP(<0.45) losses from manure application to the environment.

AN - 67928643; 15747324 AB - A probabilistic model was developed to estimate target and non-target avian mortality associated with the application of the avicide CPTH (3-chloro-p-toluidine hydrochloride) to minimize sprouting rice damage in the southern USA. CPTH exposures for individual birds were predicted by random sampling from species-specific non-parametric distributions of bait seed consumption and CPTH residues detected on individual bait seeds. Mortality was predicted from the species-specific exposure versus mortality relationship. Individual variations in this response were captured in the model by Monte Carlo sampling from species-specific distributions of slopes and median toxicity values (LD50) for each bird. The model was used to simultaneously predict mortality (percentage of exposed population and number of birds killed/weight of consumed bait) for a target (blackbird) and non-target (mourning dove) species feeding on bait sites for up to five consecutive days.

AN - 67928613; 15712354 AB - Multiple seeded cocklebur has been found in the last decade in Texas, and described as a biotype of Xanthium strumarium L with up to 25 seeds per bur instead of the usual two. The multiple seeded bur typically produces up to nine seedlings, causing concern that it may be harder to control than normal seeded common cocklebur. The efficacies of a series of fungal and conventional commercial herbicides have been compared in the greenhouse on seedlings of multiple seeded cocklebur from Texas (MSC-TX) and normal common cockleburs from Texas (NCC-TX), Arkansas (NCC-AR), Illinois (NCC-ILL) and two from Mississippi (NCC-MS#1, NCC-MS#2). Three measures of herbicidal activity (reductions in plant height and dry weight, and mortality) were used. The fungal herbicide Alternaria helianthi (Hansf) Tubaki & Nishihara at 1 x 10(5) conidia ml(-1) + 2 g liter(-1) Silwet L-77 with an 8-h dew period was an effective herbicide with all biotypes, as were the commercial chemical herbicides chlorimuron (14.8 g ha(-1)), imazaquin (29.6 g ha(-1)), sodium hydrogen methylarsonate (MSMA; 279.1 g ha(-1)) and imazethapyr (39.5 g ha(-1)). The membrane-disrupting organic arsenical MSMA was effective with all biotypes, whereas commercial chemical herbicides which act by inhibiting branched-chain amino acid synthesis (chlorimuron, imazaquin and imazethapyr) were less effective against normal seeded common cocklebur biotypes with short stature. These studies showed that multiple seeded cocklebur was at least as susceptible to the biological agent A helianthi and to the conventional commercial herbicides studied as were normal seeded cockleburs, suggesting that existing methods should be adequate to control this novel biotype.

AN - 67880527; 15899490 AB - Tibial dyschondroplasia (TD) is a metabolic cartilage disease of young poultry in which endochondral bone formation is disrupted leading to the retention of a non-calcified, avascular plug of cartilage in the tibial growth plate. Chicks aged 7 days were fed either a control diet or one containing thiram 100 ppm for 48 h to induce TD. Cell multiplication in the growth plate was determined thereafter with bromodeoxyuridine (BrdU) labelling, and metabolic changes by measuring alkaline phosphatase (ALP), tartrate-resistant acid phosphatase (TRAP), and glutathione (GSH) activities. The effect on chondrocyte maturation was examined by reverse transcriptase-polymerase chain reaction (RT-PCR) analysis of gene expression. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labelling (TUNEL) and DNA fragmentation were used to determine the effects of thiram on cell survival. The results showed that thiram-induced TD was not due to the multiplication of cells in the post-proliferative zones. Thiram did not affect ALP activity, which would have indicated a loss of calcification potential, but it reduced both TRAP and the glutathione concentrations, suggesting that the growth plate metabolism and remodelling functions were adversely affected. Thiram appeared to have no effect on the expression of type X collagen, transglutaminase, RUNX2, or matrix metalloproteinase-2 (MMP) genes suggesting that it did not alter the maturation potential of chondrocytes. On the contrary, the expressions of MMP-13 and vascular endothelial growth factor (VEGF) genes were "up-regulated," suggesting that thiram has pro-angiogenic activity. However, TUNEL assay showed that thiram induced endothelial cell apoptosis in the capillary vessels of the growth plates, as early as 10 days of age, when TD was not visually evident. The vascular death increased on subsequent days accompanied by massive death of chondrocytes in the transition zone of the growth plate. The induction of apoptosis in the growth plate was also demonstrated by DNA fragmentation. It was concluded that thiram induced TD not through an increase in the multiplication of chondrocytes in the transition zone and not by altering the expression of genes causing the arrest of chondrocytes in a prehypertrophic state, but by creating a metabolic dysfunction which led to the destruction of blood capillaries in the transition zone chondrocytes.

Recognizing this, the Job Access and Reverse Commute (JARC) program was established in 1998 to assist states and localities develop transportation services to connect welfare recipients and other low-income residents to jobs and other support programs. This study documents case studies of eight rural areas receiving JARC funding in 1999. The report highlights specific program elements, including the implementation process, transportation services provided, and the solutions developed to deal with the challenges of distance and low population densities that rural transit systems frequently face.

This review examines our current understanding of mechanisms of Al toxicity, as well as the physiological, genetic and molecular basis for Al resistance. Al resistance can be achieved by mechanisms that facilitate Al exclusion from the root apex (Al exclusion) and/or by mechanisms that confer the ability of plants to tolerate Al in the plant symplasm (Al tolerance). Compelling evidence has been presented in the literature for a resistance mechanism based on exclusion of Al due to Al-activated carboxylate release from the growing root tip. More recently, researchers have provided support for an additional Al-resistance mechanism involving internal detoxification of Al with carboxylate ligands (deprotonated organic acids) and the sequestration of the Al-carboxylate complexes in the vacuole. This is a field that is entering a phase of new discovery, as researchers are on the verge of identifying some of the genes that contribute to Al resistance in plants. The identification and characterization of Al resistance genes will not only greatly advance our understanding of Al-resistance mechanisms, but more importantly, will be the source of new molecular resources that researchers will use to develop improved crops better suited for cultivation on acid soils.

Wheat curl mite transmissibility was abolished by replacement of WSMV HC-Pro with homologues of an aphid transmitted potyvirus (Turnip mosaic virus), a rymovirus (Agropyron mosaic virus) vectored by a different eriophyid mite, or a closely related tritimovirus (Oat necrotic mottle virus; ONMV) with no known vector. In contrast, both WSMV-Sidney 81 and a chimeric WSMV genome bearing HC-Pro of a divergent strain (WSMV-El Batan 3; 86% amino acid sequence identity) were efficiently transmitted by A. tosichella. Replacing portions of WSMV-Sidney 81 HC-Pro with the corresponding regions from ONMV showed that determinants of wheat curl mite transmission map to the 5'-proximal half of HC-Pro. WSMV genomes bearing HC-Pro of heterologous species retained the ability to form virions, indicating that loss of vector transmissibility was not a result of failure to encapsidate. Although titer in systemically infected leaves was reduced for all chimeric genomes relative to WSMV-Sidney 81, titer was not correlated with loss of vector transmissibility. Collectively, these results demonstrate for the first time that HC-Pro is required for virus transmission by a vector other than aphids.

Projected canopy area yielded slightly more precise estimates of biomass and nutrient concentrations than the sum of stem basal diameters at the soil surface. All such equations were significant (p=0.70, except dead wood and large stems of one species. These equations are potentially useful for estimating woody biomass and nutrient content from remotely sensed or field survey data, and in evaluating models of ecosystem biogeochemistry.

In this study, we compared four different protein extraction/solubilization methods-urea, thiourea/urea, phenol, and a modified trichloroacetic acid (TCA)/acetone-to determine their efficacy in separating soybean seed proteins by 2D-PAGE. In all four methods, seed storage proteins were well separated by 2D-PAGE with minor variations in the intensity of the spots. The thiourea/urea and TCA methods showed higher protein resolution and spot intensity of all proteins compared with the other two methods. In addition, several less abundant and high molecular weight proteins were clearly resolved and strongly detected using the thiourea/urea and TCA methods. Protein spots obtained from the TCA method were subjected to mass spectrometry analysis to test their quality and compatibility. Fifteen protein spots were selected, digested with trypsin, and analyzed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and liquid chromatography mass spectrometry (LC-MS). The proteins identified were beta -conglycinin, glycinin, Kunitz trypsin inhibitor, alcohol dehydrogenase, Gly m Bd 28K allergen, and sucrose binding proteins. These results suggest that the thiourea/urea and TCA methods are efficient and reliable methods for 2D separation of soybean seed proteins and subsequent identification by mass spectrometry.

AN - 20239021; 7173729 AB - Poor bioavailability of dietary iron, especially from diets rich in cereals and legumes, is a major factor contributing to the high prevalence of nutritional iron deficiency in developing countries. Dietary modification to increase intake of components that promote iron absorption from low-bioavailability meals is an effective strategy for combating nutritional iron deficiency. Prebiotics are nondigestible oligosaccharides that selectively stimulate the growth and activity of specific species of bacteria in the colon with benefits to human health. Common prebiotics such as inulin and fructooligosaccharides occur naturally in a wide variety of plant-based foods and have recently been suggested to have an enhancing effect on iron absorption. The hypothesis that prebiotics enhance iron absorption is biologically plausible because fermentation of prebiotics by natural microflora present in the colon may decrease the pH of the luminal content, promote reduction of Fe(lll) to Fe(ll), stimulate proliferation of epithelial cells to expand the absorptive surface area, and potentially stimulate expression of mineral-transport proteins in epithelial cells. However, data available in the literature characterizing the enhancing properties of prebiotics on iron absorption are inconsistent, and mechanisms of actions involved are poorly understood. The notion that the colon can function as a significant site of iron absorption in response to stimulation by prebiotics, and the effect of long-term exposure to prebiotics on the iron status of iron-deficient subjects remain to be clarified. This review discusses the functional properties of prebiotics as a promising dietary factor that enhances iron absorption.

The potential for this to occur was investigated for the fungicide, tebuconazole ([alpha]-[2-(4-chlorophenyl)ethyl]-[alpha]-(1,1- dimethylethyl)-1H-1,2,4-triazole-1-ethanol), when used for peanut (Arachis hypogaea L.) production. Soil samples were collected from peanut plots after each of four tebuconazole applications at 2-wk intervals. Soil moisture was adjusted to field capacity as necessary and samples were incubated in the laboratory for 63 d at 30 not equal to . Untreated plot samples spiked with the compound served as controls. Results indicated accelerated dissipation in field- treated samples with the time to fifty percent dissipation (DT sub(50)) decreasing from 43 to 5 d after three tebuconazole applications. Corresponding increases in rates of accumulation and decay of degradates were also indicated. Best-fit equations (r super(2) = 0.84-0.98) to dissipation kinetic data combined with estimates of canopy interception rates were used to predict tebuconazole and degradates concentration in soil after each successive application. Predicted concentrations compared with values measured in surface soil samples were from twofold less to twofold greater. Use of kinetic data will likely enhance assessments of treatment efficacy and human and ecological risks from normal agronomic use of tebuconazole on peanut. However, the study indicated that varying soil conditions (in particular, soil temperature and water content) may have an equal or greater impact on field dissipation rate than development of accelerated dissipation. Results emphasize that extension of laboratory-derived kinetic data to field settings should be done with caution.

To produce data towards the development of a predictive growth model, a 6-strain cocktail of L. monocytogenes was inoculated onto the surface of a shrimp-crabmeat product, mixed with mayonnaise that was previously adjusted with NaOH to pH 3.7, 4.0, 4.4, 4.7 or 5.1, and then stored at 4 degree , 8 degree or 12 degree C under both aerobic and vacuum conditions. At each storage temperature, L. monocytogenes was able to grow in the seafood salad under both aerobic and vacuum conditions. The slowest growth of L. monocytogenes was observed in seafood salad with a mayonnaise pH of 3.7 and a storage temperature of 4 degree C under vacuum condition. In salad with the same mayonnaise pH, the growth rate (GR, log sub(10) cfu/h) of L. monocytogenes increased as a function of storage temperature. At the same storage temperature, the lag phase duration (LPD, h) of L. monocytogenes decreased as mayonnaise pH increased. At the same mayonnaise pH and temperature, LPD of L. monocytogenes was greater under aerobic than under vacuum conditions. Regression analyses indicated that mayonnaise pH is the main effector on the LPD of L. monocytogenes in seafood salad, and storage temperature was the main effector on the GR. Secondary models that describe LPD and GR of L. monocytogenes in seafood salad as a function of mayonnaise pH and storage temperature were produced.

Pseudomonas oleovorans NRRL B-14682 and Pseudomonas corrugata 388 grew and synthesized poly(3-hydroxybutyrate) (P3HB) and medium-chain-length PHA (mcl-PHA) consisting primarily of 3-hydroxydecanoic acid (C sub(10:0); 44 plus or minus 2 mol%) and 3-hydroxydodecenoic acid (C12:1; 31 plus or minus 2 mol%), respectively, from glycerol at concentrations up to 5% (v/v). Cellular productivity maximized at 40% for P. oleovorans in 5% (v/v) glycerol and 20% for P. corrugata in 2% (v/v) glycerol after 72 h. Increasing the glycerol media concentration from 1% to 5% (v/v) caused a 61% and 72% reduction in the molar mass (M sub(n)) of the P3HB and mcl-PHA polymers, respectively. Proton-NMR analysis of the glycerol-derived P3HB revealed that the M sub(n) decrease was the result of esterification of glycerol onto the polymer in a chain terminating position. However, no evidence of glycerol-based chain termination was present in the mcl-PHA. The growth patterns of P. oleovorans and P. corrugata on glycerol permitted their use as mixed cultures to produce natural blends of P3HB and mcl-PHA. By incorporating a staggered inoculation pattern and varying the duration of the fermentations, P3HB/mcl-PHA ratios were achieved that varied from 34:66 to 96:4.

Field spectral measurements showed that moderately damaged and severely damaged plants had lower visible and near-infrared reflectance values than healthy plants. Healthy, moderately damaged, and severely damaged giant salvinia plants could be differentiated in an aerial color-infrared photograph of the study site. Computer analysis of the photograph showed that the three damage level classes could be quantified.

The imagery had four bands (blue, green, red, and near-infrared) and contained 11-bit data. Three subsets of the satellite image were extracted and used as study sites. Unsupervised classification techniques were used to classify false color (green, red, and near-infrared bands) and normal color (blue, green, and red bands) composite images of each site. Accuracy assessments performed on the classification maps of the three sites had producer's and user's accuracies for giant reed that ranged from 86% to 100%. Both false color and normal color satellite imagery did an excellent job in distinguishing giant reed infestations.

Eight species of Bacillus, including five new species, and one new species of Kurthia were isolated from the cigarettes. Some of these species have been identified elsewhere as causes of hypersensitivity pneumonitis and other respiratory syndromes. All of the isolates were facultative anaerobes, and many displayed mucoid growth under anaerobic conditions. In addition, many isolates also displayed the ability to form surface biofilms under liquid culture. Although biofilm formation and mucoid growth were not correlated, the former was found to be much more pronounced under anaerobic conditions as opposed to aerobic ones. The implications of these findings are discussed.

Solms), is a serious problem in the Sacramento / San Joaquin Delta, California. There is little published information on its phenology or seasonal growth in this system. Waterhyacinths were sampled at 2 to 3 week intervals from November, 1995 to July, 1997 and the following measurements were made on individual plants: dry weight, height, number of living leaves, number of dead leaves, and the width of the largest lamina. Lamina area per plant was estimated by multiplying the number of living leaves by the mean lamina area for each sampling date. We also noted the presence or absence of flowers. Height and dry weight increased from less than 10 cm in winter and early spring to more than 80 cm in late summer and from 10 g to 85 g, respectively. Number of dead leaves was greatest in the winter and declined through June. New leaves started to appear in March. Starting in March, lamina area per plant increased through October. Plants with flowers were present at the sample site from May 20 to August 12 but not abundant. A logistic regression equation relating relative lamina area per plant to accumulated degree-days was developed. Maximum growth was achieved in October, later than previously reported for waterhyacinth in southeast U.S. populations.

These fish were collected to provide time- and site-dependent contaminant residue data needed by researchers and managers to fill critical data gaps regarding trends and behavior of persistent organic contaminants in the Great Lakes ecosystem. In the present study, data are presented for concentrations of several organochlorine (OC) contaminants in the archived smelt, including DDT, polychlorinated biphenyls (PCBs), toxaphene, and chlordanes in Lakes Michigan and Huron (MI, USA) and in Lake Superior (MN, USA). The trends for all the OCs were declining as a first-order decay over the sampled time series (1983/1985-1993/1999) with the exception of toxaphene in Lake Superior and PCBs at the Charlevoix/Little Traverse Bay site in Lake Michigan. Concentration of the emerging contaminant, polybrominated diphenyl ethers (PBDEs), also was traced from its apparent entry into this ecosystem in approximately 1980 until 1999. Time trends for the PBDEs were increasing exponentially at all sites, with concentration-doubling times varying from 1.58 to 2.94 years.

The objectives of this study were to evaluate the effect of dairy manure application on 1) P released from surface soil by rainfall, 2) P removed from surface soil by runoff, and 3) soil P available for plants. A technique implementing a Soil Survey Laboratory method and USDA Runoff Model was applied on four Texas and three Utah soils. The application of manure (100Mg/ha) considerably increased the amount of P released from the surface soil by rainfall, but there was no significant change in the pattern of P release (phosphorus release characteristics). Manure application increased both the runoff and available P for soils. For the Blanket soil (Texas), P released from surface soil by rainfall increased from 1.06 to 30.8kg/ha/yr. The runoff P (kg/ha/yr) increased from 0.18 to 5.15 for fallow, from 0.16 to 4.71 for cropland, and from 0.13 to 3.88 for grassland. Soil P available for plants increased from 0.8,0.90, and 0.93 to 25.7, 26.1, and 26.9kg/ha/yr for fallow, cropland, and grassland, respectively. Similar effects of manure application were noticed for other Texas and Utah soils. The data suggest that manure could provide substantial amounts of available P for crop production in these soils. However, irrigated cropland amended annually with manure could contribute to nonpoint source pollution of surface freshwater bodies. The technique provides a tool to quantify the impact of manure application to agricultural land on water resources.

To this end, NASA's Airborne Visible Infra-red Imaging Spectrometer was flown over the infestation front in the Catskills region of New York during the summer of 2001. Mixture Tuned Matched Filtering in ENVI was used to "unmix" spectra and quantify the hemlock signature contribution to each pixel. The resulting percent hemlock basal area coverage correctly identified hemlock dominated pixels (> 40% basal area) with 83% accuracy. Key wavelengths and health indices were examined to determine if a subset of wavelengths could accurately predict an 11-class decline rating system. A linear regression based on reflectance at a chlorophyll sensitive wavelength (R683 nm), coupled with a water band index (R970/R900), was able to predict decline with 85% accuracy. The extreme accuracy at the low (0-3) end of the range indicated that these wavelengths might be used to assess early decline, before visual symptoms are apparent in the field.

One potential solution to these challenges is the use of ground-based photographic technology. Our objective was to develop a photo-based technique that could be used to monitor changes in willow (Salix spp.) biomass over time and estimate changes in biomass associated with herbivory. We focused on young willows ( less than or equal to 2 m in height) because this size class represents a critical life history stage for establishment of willow clumps. In August 2000 and 2001, we harvested 25 willow (Salix boothii Dorn.) clumps and clamped them in front of a fluorescent orange photoboard (150200 cm). Clumps were defoliated of leaves and tips of current annual stem growth (referred to as 'biomass') by hand in 4 to 7 increments and photographed before and after each removal. Images were scanned to digital format and the degree of photoboard obstruction was determined with Adobe registered Photoshop registered 4.0 software. Regression analysis indicated that visual obstruction of the photoboard was a good predictor of total clump biomass (r2=0.89, P<0.01) as well as biomass remaining following sequential defoliations (r2=0.92, P<0.01). These results suggest our technique provides a reliable index of both willow biomass and utilization within the size class of willow tested. Results might differ with larger willows and increased woody biomass. The technique minimizes observer bias and provides a permanent photo record that can be reanalyzed at a later date if necessary.

A strip transect from dune line to the shore improved an already successful design for monitoring raccoons, and was also sensitive for armadillos. The data were integrated into predator management operations to effectively and efficiently remove the species responsible for turtle nest predation. Tracking plot data also served to validate predator patterns of behavior relative to turtle nesting and improve prospects for preventive predator management strategies. Perhaps the most important finding is that predation at a beach historically suffering nearly complete losses (95%) of marine turtle nests had nest predation reduced to nominal levels (9.4%). For 2002 this predation level represents an estimated 69,000 additional hatchling turtles produced over historical predation rates, and 16,700 additional hatchlings over the previous lowest predation rate.

Butanol fermentation is also known as acetone butanol ethanol (ABE) or solvent fermentation. Adsorbents such as silicalite, resins (XAD-2, XAD-4, XAD-7, XAD-8, XAD-16), bone charcoal, activated charcoal, bonopore, and polyvinylpyridine have been studied. Use of silicalite appears to be the more attractive as it can be used to concentrate butanol from dilute solutions (5 to 790-810 g L super(-1)) and results in complete desorption of butanol (or ABE). In addition, silicalite can be regenerated by heat treatment. The energy requirement for butanol recovery by adsorption-desorption processes has been calculated to be 1,948 kcal kg super(-1) butanol as compared to 5,789 kcal kg super(-1) butanol by steam stripping distillation. Other techniques such as gas stripping and pervaporation require 5,220 and 3,295 kcal kg super(-1) butanol, respectively.

Research objectives were 1) to determine the density of H. virescens on field-collected H. axyridis adults held in the laboratory, and 2) to determine H. virescens presence, density, and distribution on H. axyridis adults in the field. In the laboratory, male and female H. axyridis adults hosted >150 H. virescens mature thalli (i.e., fruiting bodies); distributed primarily on the elytra and abdomen. At the overwintering site, H. virescens density per host was often <20 mature thalli, which were distributed primarily on the elytra of both sexes. On average, 52.5 and 57.4% of H. axyridis males and females, respectively, hosted H. virescens mature thalli in late winter (5 March 2003); <14% of either sex hosted mature thalli the following fall (15, 22, and 28 October and 10 November 2003) at the same site. This study suggests that H. virescens is an established parasite of H. axyridis in Pennsylvania but that field estimates of infection may vary considerably between dates that adult beetles arrive and depart from overwintering sites. Preponderance of fungal thalli on the dorsum rather than the ventrum of H. axyridis males suggests that mating behavior is not solely responsible for transmission of H. virescens from infected to noninfected adults.

RSM amendment reduced infection by native and introduced isolates of Rhizoctonia spp. and recovery of Pratylenchus spp. from apple roots. Root infection by Rhizoctonia solani AG-5 was also suppressed in split-root assays where a portion of the root system was cultivated in RSM-amended soils and the remainder grown in the presence of the pathogen but lacking RSM. R. solani hyphal growth was not inhibited by RSM amendment. Suppression of Pratylenchus was attained to an equivalent extent by amending soils with either RSM or soybean meal (SM) when applied to provide a similar N content. Thus, glucosinolate hydrolysis products did not appear to have a significant role in the suppression of Rhizoctonia spp. or Pratylenchus spp. obtained via RSM amendment. RSM amendment elevated populations of Pythium spp. and of ammonia-oxidizing bacteria that release nitric oxide but suppressed fluorescent pseudomonad numbers. Streptomyces spp. soil populations increased significantly in response to RSM but not SM amendment. The vast majority of Streptomyces spp. recovered from the apple rhizosphere produced nitric oxide and possessed a nitric oxide synthase homolog. We propose that transformations in the bacterial community structure are associated with the observed control of Rhizoctonia root rot, with NO production by soil bacteria potentially having a role in the induction of plant systemic resistance.

Here, we examine the ability of D. chlororespirans to debrominate and deiodinate the polysubstituted herbicides bromoxynil (3,5-dibromo-4-hydroxybenzonitrile), ioxynil (3,5-diiodo-4-hydroxybenzonitrile), and the bromoxynil metabolite 3,5-dibromo-4-hydroxybenzoate (DBHB). Stoichiometric debromination of bromoxynil to 4-cyanophenol and DBHB to 4-hydroxybenzoate occurred. Further, bromoxynil (35 to 75 mu M) and DBHB (250 to 260 mu M) were used as electron acceptors for growth. Doubling times for growth (means plus or minus standard deviations for triplicate cultures) on bromoxynil (18.4 plus or minus 5.2 h) and DBHB (11.9 plus or minus 1.4 h), determined by rate of [ super(14)C]lactate uptake into biomass, were similar to those previously reported for this microorganism during growth on pyruvate (15.4 h). In contrast, ioxynil was not deiodinated when added alone or when added with bromoxynil; however, ioxynil dehalogenation, with stoichiometric conversion to 4-cyanophenol, was observed when the culture was amended with 3-chloro-4-hydroxybenzoate (a previously reported electron acceptor). To our knowledge, this is the first direct report of deiodination by a bacterium in the Desulfitobacterium genus and the first report of an anaerobic pure culture with the ability to transform bromoxynil or ioxynil. This research provides valuable insights into the substrate range of D. chlororespirans.

Although conventional microarray subtyping analysis has been shown to be both high resolution and genetically informative, it is still relatively low throughput and technically challenging. Suspension microarray technology eliminates the technical issues associated with planar microarrays and allows high-throughput subtyping of L. monocytogenes strains. In this study, a suspension array assay using dendrimer signal amplification allowed rapid and accurate serovar identification of L. monocytogenes strains using genomic DNA as a target. The ability to subtype genomic DNA without PCR amplification allows probes to be designed for many different regions within the bacterial genome and should allow high-resolution subtyping not possible with multiplex PCR.

Forest water yield from the southeastern US varies greatly both in space and time. Because of the hot climate and high evapotranspiration, less than half of the annual precipitation that falls on forest lands is available for stream flow in this water-rich region. Water yield is highest in the mountainous regions that receive the highest precipitation and have the lowest air temperature, and the lowest in the coastal regions that are dominated by wetlands receiving moderate rainfall but high evapotranspiration. Water resource management for both floods and droughts demands an accurate estimation of water yield from forests. Projected climate and land use changes further increase the variability of water yield in the region. The objectives of this study were to (1) develop a simple annual water yield modeling procedure by testing and calibrating a generalized global evapotranspiration model, (2) to apply the validated model to estimate regional forest water yield and to predict potential water yield response to forest removal. Hydrologic databases at a watershed-scale and a regional-scale were developed for model development, calibration, and validation. We applied the water yield model to the southern region by integrating land cover and high resolution climate databases by using a Geographic Information System (GIS). The model developed in this paper can be used to examine the spatial and temporal variability for water yield and predict the effects of climate and land cover changes at the regional scale.

Previous studies have shown that climate and soil conditions control net primary production (NPP) at regional scales, and that agricultural land use can influence NPP at local scales through altered water availability and carbon allocation patterns. However, few studies have attempted to quantify the effect of cultivation on NPP at regional scales, and no studies have examined this relationship for the most heavily cultivated region of the United States, the Great Plains. We quantified current regional aboveground and belowground productivity (including cultivation) for nine years on a county basis from (1) USDA agricultural census data, and (2) STATSGO range site production values. By comparing these data with values of native vegetation NPP (precultivation) derived from STATSGO, we estimated that cultivation is increasing regional NPP by similar to 10%, or 0.046 Pg C/yr. In addition, we examined the relationship between cultivation of particular crops and NPP change and characterized the influence of individual crops on primary productivity.

Such insights provide constructive information for current or future biological control research efforts. In this study, we investigated a highly variable chloroplast DNA (cpDNA) marker for populations of the weed Lepidium draba (Brassicaceae) in its native Eurasian and invasive US ranges. We sequenced DNA from 684 individuals from Eurasia and the US and found 41 different haplotypes. Our comparative study between the native and invasive ranges showed a 33% reduction in allelic richness (A) and a 7% reduction in haplotype diversity (h) since introduction into the US. Most genetic variation in the native range was observed within geographical regions and populations, not between regions, and this result was similar for the invasive range. Assignment tests indicated the most likely origins of many invasive haplotypes. Some of these occurred in western Europe, supporting an expanded native range that had been proposed for the species. Exact locations were identified for a diverse set of invasive haplotypes which can be used in ongoing host-specificity tests of potential biological control agents.

These cattle produce large quantities of manure. It has been suggested excess dairy manure could be applied to rangelands as an organic fertilizer to increase soil fertility and herbaceous production. Manure was applied June 2000 to a rangeland in New Mexico dominated by blue grama (Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths) according to phosphorus (P) content: a recommended (light) rate (54 kg P.ha super(-1)) to enhance blue grama growth and a gross overapplication (heavy) rate (493 kg P.ha super(-1)) to determine their effects on vegetation. The actual application rate of manure on a dry weight basis was 0, 11 739, and 107 174 kg.ha super(-1). Four replications of control, light, and heavy rates were established. Herbaceous standing crop (kg.ha super(-1)) was similar 1 growing season after manure application, and greater 2 and 3 growing seasons after application on the light treatment compared with the control. Initially the heavy treatment suppressed herbaceous standing crop; thereafter, standing crop responded in a linear fashion to rainfall. Three growing seasons after manure application, basal cover was similar between light and control treatments, whereas the heavy treatment continued to be characterized principally by manure/litter cover. Heavy disposal-oriented treatments are not suitable for blue grama rangelands because of persistent declines in herbaceous cover and changes in soil salinity. A light manure application rate that is based on P content can increase forb and in particular grass standing crop on arid blue grama rangelands. Successful rangeland manure applications will depend on proper management to insure objectives are met while minimizing any hazards to the environment.Original Abstract: Nuevo Mexico sostiene cerca de 290 000 vacas lecheras. Este ganado produce grandes cantidades de estiercol y se ha sugerido que el exceso de estiercol de ganado lechero pudiera ser aplicado en pastizales como fertilizante organico para incrementar la fertilidad del suelo y la produccion de la vegetacion herbacea. En Junio del 2000 se aplico estiercol en pastizales de Nuevo Mexico dominados por el zacate 'Blue grama' (Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths), con el objetivo de ver el impacto de la aplicacion sobre la vegetacion. De acuerdo al contenido de fosforo (P), las aplicaciones fueron: la cantidad recomendada (ligera) de 54 kg P.ha super(-1) para mejorar el crecimiento del zacate 'Blue grama' y una cantidad que representa una sobre aplicacion (fuerte) de 493 kg P.ha super(-1). La cantidad de estiercol aplicada en base a peso seco fue 0, 11 739, y 107 174 kg.ha super(-1). Se establecieron cuatro repeticiones del control, cantidad ligera, y cantidad fuerte. En la primera estacion de crecimiento despues de la aplicacion de estiercol, la produccion de biomasa en pie de la vegetacion herbacea (kg.ha super(-1)) fue similar entre tratamientos y en la segunda y tercera estaciones de crecimiento la produccion de biomasa en la aplicacion ligera fue superior que al tratamiento control. El tratamiento fuerte inicialmente redujo la produccion de biomasa herbacea, pero posteriormente el pasto respondio de manera linear a la lluvia. Tres estaciones de crecimiento despues de la aplicacion del estiercol la cobertura basal fue similar entre el tratamiento ligero y el control, mientras que el tratamiento fuerte continuo caracterizandose principalmente por la cobertura de estiercol/mantillo. Los tratamientos orientados a la aplicacion fuerte como medio de utilizacion del exceso de estiercol no son apropiados para pastizales de zacate 'Blue grama' debido a la disminucion persistente de la en cobertura herbacea y cambios en la salinidad del suelo. Una aplicacion ligera de estiercol basada en P puede incrementar la produccion de hierba y particularmente la biomasa de pasto en pastizales aridos de 'Blue grama'. Las aplicaciones exitosas de estiercol en pastizales dependeran de manejo apropiado para asegurar que los objetivos se cumplan mientras se minimiza cualquier riesgo para el medio ambiente.

Past research has used a perpendicular root reinforcement model that assumes that all of the tensile strength of the roots is mobilized instantaneously at the moment of bank failure. In reality, as a soil- root matrix shears, the roots contained within the soil have different tensile strengths and thus break progressively, with an associated redistribution of stress as each root breaks. This mode of progressive failure is well described by fiber bundle models in material science. In this paper, we apply a fiber bundle approach to tensile strength data collected from 12 riparian species and compare the root reinforcement estimates against direct shear tests with root-permeated and non-root-permeated samples. The results were then input to a stream bank stability model to assess the impact of the differences between the root models on stream bank factor of safety values. The new fiber bundle model, RipRoot, provided more accurate estimates of root reinforcement through its inclusion of progressive root breaking during mass failure of a stream bank. In cases where bank driving forces were great enough to break all of the roots, the perpendicular root model overestimated root reinforcement by up to 50%, with overestimation increasing an order of magnitude in model runs where stream bank driving forces did not exceed root strength. For the highest bank modeled (3 m) the difference in factor of safety values between runs with the two models varied from 0.13 to 2.39 depending on the riparian species considered. Thus recent work has almost certainly overestimated the effect of vegetation roots on mass stability of stream banks.

Pichia pastoris is a very useful organism to express proteins that are inactive in other hosts such as Escherichia coli and Saccharomyces cerevisiae. However, most P. pastoris expression plasmids are designed to integrate into the host chromosome and hence are not as amenable to high-throughput screening projects. We have designed a P. pastoris expression vector, pBGP1, incorporating an autonomous replication sequence that allows the plasmid to exist as an episomal element. This vector contains the alpha -factor signal sequence to direct secretion of the mutant enzymes. Expression of the genes is driven by the constitutive GAP promoter, thus eliminating the need for timed or cell density-specific inductions. The pBGP1 plasmid was used to screen a xylanase gene library to isolate higher activity mutants.

Breeding Lines For Molecular Breeding AN - 17602270; 6485858 AB - Development of an efficient transformation method for recalcitrant crops such as sugar beet (Beta vulgaris L.) depends on identification of germplasm with relatively high regeneration potential. Individual plants of seven sugar beet breeding lines were screened for their ability to form adventitious shoots on leaf disk callus. Disks were excised from the first pair of true leaves of 3-wk-old seedlings or from partially expanded leaves of 8-mo.-old plants and cultured on medium with 4.4 mu M 6-benzylaminopurine for 10 wk. At 5 wk of culture, friable calluses and adventitious shoots began to develop. Rates of callus and shoot formation varied between breeding lines and between individual plants of the same line. Line FC607 exhibited the highest percentage (61%) of plants that regenerated shoots on explants. Among the plants with a positive shoot regeneration response, line FC607 also had the highest mean number (8.3 plus or minus 1.1) of shoots per explant. Individual plants within each line exhibited a wide range of percentages of explants that regenerated shoots. A similar variation was observed in the number of shoots that regenerated per explant of an individual plant. No loss of regeneration potential was observed on selected plants maintained in the greenhouse for 3 yr. Regenerated plants exhibited normal phenotypes and regeneration abilities comparable to the respective source plants. Based on our results, it is imperative to screen a large number of individual plants within sugar beet breeding lines in order to identify the high regenerators for use in molecular breeding and improvement programs.

The recent development of plant viruses as transient expression vectors has not only enhanced our understanding of virus biology and antiviral defense mechanisms in plants, but has also led to the use of plant viral-based vectors as tools for gene discovery and production of recombinant proteins in plants for control of human and animal diseases. An overview of the state-of-the-art of viral expression systems is presented, as well as examples from our laboratory on their use in identifying nuclear targeting motifs on viroid molecules and development of therapeutic proteins for control of animal diseases.

The strain was subjected to a polyphasic study using standard methods for chemotaxonomic, morphological and physiological evaluation. The strain exhibited chemotaxonomic characteristics distinct from Glycomyces in spite of having 16S rRNA gene sequence similarity of 92% with the described species of this genus. The whole-cell sugar pattern of NRRL B-16338 super(T) consisted of ribose and inositol, with traces of arabinose and mannose. The phospholipids observed were phosphatidylglycerol and diphosphatidylglycerol and menaquinones consisting of MK-10(H sub(4)), MK-10(H sub(6)), MK-11(H sub(4)) and MK-11(H sub(6)). A significant quantity (14 times 5%) of 17: 0 anteiso 2-hydroxy fatty acid was observed in the fatty acid profile of this strain. These characteristics clearly differentiate NRRL B-16338 super(T) from members of the genus Glycomyces and it is proposed that the strain represents a new genus within the family Glycomycetaceae to be called Stackebrandtia gen. nov. The description of this family is emended to permit its inclusion. It is proposed that the type species of the genus should be named Stackebrandtia nassauensis. The type strain LLR-40K-21 super(T) (=NRRL B-16338 super(T)=DSM 44728 super(T)) was isolated from a soil sample from Nassau, Bahamas.

Herein we summarize corn (Zea mays L.) response to the LSNT program when implemented across the Clarion-Nicollet-Webster soil association. The LSNT was used to determine the recommended N fertilizer rate that was applied uniformly across each field except on check strips where zero or nonlimiting (>220 kg N ha super(-1)) sidedress N was applied. Leaf chlorophyll (SPAD) readings, end-of-season stalk nitrate concentrations, and grain yield and quality (protein, starch, and oil content) showed significant year, field, soil map unit and N rate response. Average grain yield with the LSNT program was significantly lower than the nonlimiting rate in 1997 and 1998 but not in 1999 or 2000. This suggests that although watershed- scale implementation of the LSNT can reduce nitrate loss through drainage water, it may also increase producer risk, especially when above-normal rainfall occurs shortly after the sidedress N fertilizer is applied. To encourage adoption of the LSNT program for its water quality benefits, we suggest that federal, state, or private agencies develop affordable risk insurance or some other financial incentives to help producers minimize the potential crop risk associated with this program.

This study was undertaken to identify those agronomic and microclimatic factors that influence grain yield of corn grown in narrow and wide conventional rows. A split plot experimental design was established near Morris, MN, in 1998 and 1999 with row spacing (0.38, 0.57, and 0.76 m) as the main treatment and corn hybrid (Pioneer 3893 and DeKalb 417) as the secondary treatment. Root length density, crop water use, interception of photosynthetically active radiation (PAR), soil temperature, and soil evaporation were measured in each row-spacing treatment during the growing season. Grain yield and water use of narrow-row corn equaled, or even exceeded, that of wide, conventional-row corn. Narrow-row corn had a more uniform root distribution and intercepted 5 to 15% more PAR on clear days, the latter of which likely aided in suppressing soil temperatures and evaporation during vegetative growth compared with corn grown in conventional rows. The results of this study suggest that any yield advantage to growing corn in narrow rows may result from establishing a more uniform root and leaf distribution that aids in exploiting soil water and light resources and reducing soil temperatures and evaporation compared with corn grown in wide conventional rows.

Public land managers desire its seed for rangeland rehabilitation. Through manual pollination field trials, the species was found to have a mixed pollination system. It is primarily xenogamous (46% of ovules yielded plump achenes) but partially self-compatible (31% of achenes were plump). Unvisited flower heads formed virtually no mature achenes; only plump achenes contained seeds with endosperm. Freely visited flower heads in 2 populations produced as many achenes as manual outcross pollinations of flower heads, suggesting that seed production was not pollinator limited. Two species of Osmia bees rely mostly on Balsamorhiza and its close relative, Wyethia, for pollen. At least 165 females per hectare will need to be stocked to achieve thorough flower visitation in cultivated seed production fields.

Models are used to predict P transport but rarely simulate P in runoff from surface-applied manures. Using field-plot data, we tested a previously proposed model to predict manure P in runoff. We updated the model to include more data relating water to manure ratio to manure P released during water extractions. We verified that this update can predict P release from manure to rain using published data. We tested the updated model using field-plot and soil-box data from three manure runoff studies. The model accurately predicted runoff P for boxes, but underpredicted runoff P for plots. Underpredictions were caused by runoff to rain ratios used to distribute P into runoff or infiltration. We developed P distribution fractions from manure water extraction data to replace runoff to rain ratios. Calculating P distribution fractions requires knowing rainfall rate and times that runoff begins and rain stops. Using P distribution fractions gave accurate predictions of runoff P for soil boxes and field plots. We observed relationships between measured runoff to rain ratios and both P distribution fractions and a degree of error in original predictions, calculated as (measured runoff P/predicted runoff P). Using independent field-plot data, we verified that original underpredictions of manure runoff P can be improved by calculating P distribution fractions from measured runoff to rain ratios or adjusting runoff to rain ratios based on their degree of error. Future work should test the model at field or watershed scales and at longer time scales.

A totla of 123 subjects completed AT (51 men, 72 women) and 83 subjects completed ST (40 men, 43 women). DNA was extracted from blood samples of all subjects and genotyping was performed at the VDR FokI and BsmI locus to determine its association to training response. Total body, greater trochanter and femoral neck bone mineral density (BMD) were measured before and after both training programmes using dual-energy X-ray absorptiometry. VDR BsmI genotype was not significantly related to BMD at baseline or after ST or AT. However, VDR FokI genotype was significantly related to ST- but not AT-induced changes in femoral neck BMD (P < 0.05). The heterozygotes (Ff) in the ST group approached a significantly greater increase in femoral neck BMD (P = 0.058) compared to f homozygotes. There were no significant genotype relationships in the AT group. These data indicate that VDR FokI genotype may influence femoral neck BMD response to ST, but not AT.

Three key wavelengths of 460, 540, and 700 nm, previously identified using a visible/near-infrared spectrophotometer, were implemented in a common-aperture multispectral imaging system, and images were collected for 174 wholesome, 75 inflammatory process, and 170 septicemic chickens. Principal component analysis was used to develop an algorithm for separating septicemic chickens from wholesome and IP chickens based on average intensity of first component images. A threshold value of 105 was able to correctly separate 95.6% of septicemic chickens. To differentiate inflammatory process chickens, a region of interest was defined from which spectral features were determined. The algorithm was able to correctly identify 100% of inflammatory process chickens by detecting pixels that satisfied the spectral feature conditions. A decision tree model was created to classify the three chicken conditions using inputs from the two image processing algorithms. The results showed that 89.6% of wholesome, 92.3% of inflammatory process, and 94.4% of septicemic chickens were correctly classified.

Time-course experiments in media containing soluble starch as substrate showed that amylolytic activity appeared in cultures at 24 h (after exponential growth had ceased), reached peak levels in 72-96 h, and declined rapidly after reaching peak levels, Peak levels were highest in TSBWD containing 1.0% soluble starch. Proteolytic activity appeared at about the same time as amylolytic activity and increased during the period of amylase production. Significant amylase production was not observed in cultures in TSBWD with 0.5% glucose or in cultures grown at 28 degree C, but low levels of amylase were observed in TSBWD cultures grown at 19-23 degree C which contained no added carbohydrate. A single band of activity was observed after electrophoresis of supernatant fractions in non-denaturing gels, followed by in situ staining for amylolytic activity. The amylase possessed a raw starch-binding domain and bound to uncooked corn, wheat or potato starch granules. It was active in the Phadebas assay for alpha -amylase. Activity was maximum on soluble starch at a temperature between 40 degree C and 50 degree C. The amylase after purification by affinity chromatography on raw starch granules exhibited two starch-binding protein bands on SDS gels of 105 kDa and 26 kDa.

Growth, Morphogenesis, and Secondary Metabolism AN - 17148579; 6789811 AB - The influence of autoclaved fungal materials such as culture filtrate, freeze-dried mycelium (FDM), mycelium suspension, and spore suspension (SS) on the growth, morphogenesis, and carvone production of spearmint (Mentha spicata L.) plants was studied. Fungal materials were either applied as a drench or spray on the plants. Spearmint plants (cv. '294099') drenched with SS (1 x 10 super(8) spores/ml) of Trichoderma reesei showed no significant differences in leaf numbers, root numbers, or shoot numbers compared with nontreated controls. However, significantly higher fresh weights and carvone levels were observed in plants drenched with T. reesei SS compared with the untreated controls. Fungal materials derived from Aspergillus sp., Fusarium graminearum, F. sporotrichoides, Penicillium sp., P. acculeatum, Rhizopus oryzae, and T. reesei were sprayed on spearmint foliage. F. graminearum, F. sporotrichoides, or R. oryzae elicited no enhanced growth, morphogenesis, or secondary metabolism responses. The best growth and morphogenesis responses were obtained employing Aspergillus sp., Penicillium sp., or T. reesei foliar sprays. For example, spearmint cv. '557807' plants sprayed with 100 mg/l FDM T. reesei isolate NRRL 11460 C30 stimulated higher fresh weights (75%), shoot numbers (39%), leaf numbers (57%), and root numbers (108%) compared with untreated plants. This effect was not dose-dependent because similar growth and morphogenesis responses were obtained by testing 10, 100, or 1000 mg/l FDM concentrations. Carvone levels in fungal-treated foliar-sprayed plants were comparable to nontreated controls. However, total carvone levels per plant were higher in fungal-treated plants because of their increased fresh weight.

CLE has subsequently been observed in promoter sequences of bacterial (T-DNA) and plant origin, suggesting a role in plant and plant viral gene regulation. Synthetic DNA cassettes harboring direct repeats of the CLE motif were placed upstream from a -46 to +1 minimal CaMV 35S promoter-luciferase reporter gene and reporter activity characterized in Nicotiana species during both transient and stable expression. A single direct-repeat cassette of the element (2 x CLE) enhances luciferase activity by 2-fold, independent of the element's orientation, while multiple copies of the cassette (4-12 x CLE) increases activity up to 10- to 15-fold in an additive manner. Transgenic tobacco lines containing synthetic CLE promoter constructs enhance luciferase expression in leaf, cotyledon and stem tissues, but to a lesser extent in roots. Single nucleotide substitution at six of eight positions within the CLE consensus (GTGGTCCC) eliminates CLE enhancer-like activity. It has been previously reported that CLE interacts with the AC2 protein from Pepper Huasteco Virus (PHV-AC2). PHV-AC2 (also called AL2 or C2) is a member of the transcriptional activator protein, or TrAP, gene family. In transient and stable expression systems PHV-AC2 expression was found to result in a 2-fold increase in luciferase activity, irrespective of the presence of CLE consensus sequences within the reporter's promoter. These data suggests that the PHV-AC2 protein, instead of interacting directly with CLE, functions as either a general transcriptional activator and/or a suppressor of post-transcriptional gene silencing.

Deviation from horizontal flow leads to asymmetrical groundwater emergence onto the surface and greater propensity for contaminant delivery to the stream. The study site, at the USDA-Beltsville Agricultural Research Center, is in the mid-Atlantic coastal plain of Maryland. The site contains a small first-order stream that is instrumented with five stations for monitoring stream flow and chemistry, and 170 nested piezometers (mostly in transects) for evaluating groundwater hydrology and geochemistry. Subsurface microstratigraphy and macroporosity are largely responsible for observed spatial and temporal variations in groundwater contributions to the stream. The portion of the stream that shows the highest rate of flow increase per stream length contains discrete zones of enhanced groundwater discharge (upwelling) to the surface, which supply most of the additional stream flow. These upwelling zones display high (positive) vertical hydraulic heads, which relate to the amount of groundwater discharged from those points. One particular area of intense groundwater upwelling supplies approximately 4% of the total stream outflow, yet comprises only 0.006% of the riparian zone. The upwelling zones also supply most of the NO sub(3) super(-) to the surface. Zones of focused groundwater exfiltration that sustain stream baseflow do not correspond with erosional features, and have a great impact on stream flow characteristics and NO sub(3) super(-) behavior. Few studies to date have elucidated and quantified contributions from specific surface features (e.g. upwelling zones, discharging macropores). More emphasis and research needs to be directed to the importance of focused groundwater exfiltration points for stream flow generation and NO sub(3) super(-) transport, with the goal of devising more effective management regulations for preserving and enhancing riparian zone mitigation function.

Online analytical processing (OLAP) can be used as a supplement to cluster analysis for fast and effective data mining of gene expression databases. We used Analysis Services 2000, a product that ships with SQLServer2000, to construct an OLAP cube that was used to mine a time series experiment designed to identify genes associated with resistance of soybean to the soybean cyst nematode, a devastating pest of soybean. The data for these experiments is stored in the soybean genomics and microarray database (SGMD). A number of candidate resistance genes and pathways were found. Compared to traditional cluster analysis of gene expression data, OLAP was more effective and faster in finding biologically meaningful information. OLAP is available from a number of vendors and can work with any relational database management system through OLE DB.

The 51 relevant items were entered into a grade-of-membership model to describe vascular damage in AD. Five latent groups were identified "I: early-onset AD," "II: controls, cancer," "III: controls, extensive atherosclerosis," "IV: late-onset AD, male," and "V: late-onset AD, female." Expectedly, Groups IV and V had elevated APOE epsilon 4 frequency. Unexpectedly, there was limited atherosclerosis and frequent myocardial valve and ventricular damage. The findings do not indicate a strong relationship between atherosclerosis and AD, although both are associated with the APOE epsilon 4. Instead, autopsy findings of extensive atherosclerosis were associated with possible, not probable or definite AD, and premature death. They are consistent with the hypothesis that brain hypoperfusion contributes to dementia, possibly to AD pathogenesis, and raise the possibility that the APOE allele epsilon 4 contributes directly to heart valve and myocardial damage.

6393933 AB - We evaluated the effects of three regeneration harvest methods on plant diversity and soil resource availability in mixed-hardwood ecosystems. The study area is in the Wine Spring Creek watershed on the Nantahala National Forest of the Southern Appalachian Mountains in western North Carolina. The regeneration treatments were: an irregular, two-aged shelterwood cut (2A), with 5.0m super(2)/ha residual basal area; a shelterwood cut (SW), with 9.0m super(2)/ha residual basal area; a group selection cut (GS), with 0.10-0.20ha openings and 25% overstory removal on area basis at first entry; fourth, the control, consisted of two uncut sites (UC). Each harvest treatment was replicated three times across the landscape in similar plant community types. Within each treatment area, permanent plots were marked and inventoried for overstory, midstory, and herbaceous layer plants. In each permanent plot, we collected soil samples in winter (December-March) to reduce temporal variation due to vegetation phenological stage and rainfall events. We analyzed soil samples for extractable calcium (Ca), magnesium (Mg), potassium (K), cation exchange capacity (CEC), pH, bulk density, A-horizon depth, total carbon (C), and nitrogen (N). Species diversity of overstory, understory, and herbaceous layer species was evaluated using species richness (S), Shannon-Wiener's index of diversity (H'), and Pielou's evenness index (E). We used direct gradient analysis (non-metric multidimensional scaling, NMS) to explore the changes in vegetation-site relationships among herbaceous layer abundance, and soil characteristics and overstory basal area between pre-harvest (1994) and post-harvest (2000). Twelve minor overstory species were cut from the 2A treatments and nine species were cut from the SW treatments. Thus, it is not surprising that S and H' were reduced in the overstory on the heavily cut sites. However, most of these species sprouted from cut stumps and were substantially more abundant in the midstory layer after harvest than before. For the midstory, we found higher S and H' on the harvested treatments than the control; however, H' did not differ significantly among the harvest treatments. We measured an increase in herbaceous layer H' on the more heavily cut treatments (2A and SW) after harvest. We found an increase in average distance in the NMS ordination among sites in 2000 compared to 1994, which suggests greater herbaceous species diversity after harvest. However, we did not see a clear separation among harvest treatments in the NMS ordination.

AN - 67913000; 15941316 AB - Sicklepod (Senna obtusifolia) is a leguminous plant that infests soybean fields in the southeastern United States. Its seeds contain a variety of toxic, highly colored compounds, mainly anthraquinones together with a small amount of fat. These compounds contaminate and lower the quality of soybean oil when inadequately cleaned soybean seed from this area is processed. The sorting of sicklepod seed from a soybean harvest is an additional economic burden on the farmer beyond the cost of proper disposal of the weed seed to avoid worsening field infestation. Fortunately, sicklepod seed also contains substantial amounts of carbohydrates and proteins. These edible components when freed from anthraquinones have a market in pet food as well as potential in human foods because of the high galactomannan ratio of the polysaccharides. Sicklepod seed was dehulled, and the ground endosperm was defatted, followed by sequential solvent extraction of the defatted seed meal to isolate the anthraquinones, carbohydrates, and protein components into their respective classes. Each class of isolate was spectroscopically identified.

In this study, several strains of bacteria that exude aluminum (Al)-chelating compounds were isolated from the rhizosphere of crested wheatgrass (Agropyron desertorum) collected from the Idaho National Laboratory (INL). We examined the effects of exudates from bacteria in the genera Bacillus, Ralstonia, and Enterobacter on cesium (Cs) desorption from illite. Exudates from these strains of bacteria significantly enhanced Cs desorption from illite. In addition, Cs desorption increased with increasing Bacillus exudate concentrations. Cesium desorption from illite as a function of both exudate type and concentration was positively correlated with Al dissolution, suggesting that the Al-complexing ability of the exudates played an important role in enhancing Cs desorption. The density of frayed edge sites (FES) on illite increased as a result of treatment with bacterial exudates, while the Cs/K selectivity of FES decreased. These results suggest that exudates from bacteria isolated from the rhizosphere can enhance Cs desorption from frayed edges of illite and, therefore, can alter Cs availability in micaceous soils.

AN - 67900617; 15824099 AB - Benzoxazolin-2(3H)-one (BOA) is an allelochemical most commonly associated with monocot species, formed from the O-glucoside of 2,4-dihydroxy-2H-1,4-benzoxazin-3(4H)-one by a two-step degradation process. The capacity of Arabidopsis to detoxify exogenously supplied BOA was analyzed by quantification of the major known metabolites BOA-6-OH, BOA-6-O-glucoside, and glucoside carbamate, revealing that detoxification occurs predominantly through O-glucosylation of the intermediate BOA-6-OH, most likely requiring the sequential action of as-yet-unidentified cytochrome P450 and UDP-glucosyltransferase activities. Transcriptional profiling experiments were also performed with Arabidopsis seedlings exposed to BOA concentrations, representing I(50) and I(80) levels based on root elongation inhibition assays. One of the largest functional categories observed for BOA-responsive genes corresponded to protein families known to participate in cell rescue and defense, with the majority of these genes potentially associated with chemical detoxification pathways. Further experiments using a subset of these genes revealed that many are also transcriptionally induced by a variety of structurally diverse xenobiotic compounds, suggesting they comprise components of a coordinately regulated, broad specificity xenobiotic defense response. The data significantly expand upon previous studies examining plant transcriptional responses to allelochemicals and other environmental toxins and provide novel insights into xenobiotic detoxification mechanisms in plants.

AN - 67866169; 15914863 AB - Comparative sequence analysis suggests that the left terminal domain of Potato spindle tuber viroid (PSTVd) and other large pospiviroids may assume a branched tertiary structure containing two pseudoknots. To search for evidence of such a structure in vivo, the nucleotide sequences proposed to interact were mutagenized, tomato seedlings were inoculated with mixtures of potentially infectious PSTVd RNA transcripts and the resulting progeny were screened for compensatory sequence changes. Positions 6-11 and 330-335 tolerated only limited sequence variation, and compensatory changes consistent with formation of an intact pseudoknot were observed in only two of the plants examined. No variation was detected at positions 14-16 or 29-31. Passage of selected variants in Rutgers tomato led to an increase in virulence only upon reversion to wild-type PSTVd_Intermediate. The ability of the left terminal domain to assume a branched conformation containing pseudoknots does not appear to be an important determinant of PSTVd fitness.

The complete 7.1 Mb genome of Pf-5 was sequenced recently by The Institute for Genomics Research. In addition to six known secondary metabolites produced by Pf-5, three novel secondary metabolite biosynthesis gene clusters were identified that may contribute to biological control. Various features were identified that contribute to the bacterium's capacity to colonize the rhizosphere, including broad catabolic and transport capabilities for utilizing root exudates and the presence of 28 outer membrane receptors for siderophore iron complexes produced by many different microorganisms. We found no evidence for a Type III secretion system or the biosynthesis of toxins found in phytopathogenic Pseudomonas spp. Analysis of the locations of over 1000 copies of repeat sequences in the Pf-5 genome suggests that six secondary metabolite gene clusters, seven phage regions and a mobile genomic island were acquired relatively recently by the bacterium.

An important facet of protecting plant resources throughout the world is preventing their introduction to new areas. Strong border controls can never be completely effective at preventing the introduction of all new plant pathogens, but to give up is to doom growers and land managers throughout the world to face relentless attacks by the numerous plant pathogens being moved by humans and in trade. Although most introduced plant pathogens can ultimately be managed to minimize their impacts, these management programs can never be as effective as preventing the introduction in the first place. With respect to internationally traded commodities that serve as a pathway for introduction of plant pathogens, another alternative for managing diseases is to conduct management programs in the export country to stop the pathway. But these approaches are not perfect either and border controls serve as effective backup.

Initial diversity was characterized for 20 diverse isolates obtained from Indonesia, Virginia, Kentucky, Connecticut, and North Carolina. An additional 175 isolates were obtained over a 4-yr period from a cultivar rotation study in Duplin Co., N.C. Only race 0 of the pathogen was detected from this field in a baseline assay, but race 1 was detected after just 1 yr of deployment of single gene resistance. Additional isolates of races 0 and 1 were obtained over the 4 yr period. From all isolates evaluated, 256 of 304 markers (85%) were polymorphic and provided 106 unique AFLP phenotypes. In the Duplin Co. field, AFLP phenotypes detected in yr one were recovered from plots throughout the 4-yr study, but additional AFLP phenotypes also were recovered each year.

To accomplish this, we are beginning an in-depth study of the proteome of P. pachyrhizi using liquid chromatography tadem mass spectrometry (LC-MS/MS). LC-MS/MS offers the inherent benefit of providing protein sequence information that can be used to specifically identify and characterize proteins in a high-throughput fashion. This technology trait can be exploited to identify proteins that define particular life cycle stages of the fungus. The knowledge of proteins that form spores, germlings, appresoria, and haustoria may be used to define host-pathogen interactions or serve as targets for chemical inhibition of the fungus. Because of Select Agent containment restrictions, we have optimized our methodology using common bean rust Uromyces appendiculatus. A description of the spore proteome is presented. Comparative proteomics between the two fungi will follow.

To begin to characterize these interactions in maize at the molecular level, the coat protein 1 (CP1) of Maize chlorotic dwarf virus (MCDV) was used as bait in a yeast two-hybrid system to identify virus-binding proteins from the susceptible maize inbred Va35. The protein encoded by prey clone 12-15 interacted very strongly and specifically with the MCDV CP1 in yeast. The 12-15 cDNA sequence encoded an open reading frame (ORF) with homology to diacylglycerol kinases, and was identical to nt 389 to 1226 of a contig of maize EST sequences (AY104898). Transcripts encoded by 12-15 were expressed at low levels in both susceptible and resistant maize. In addition, no cell type-specific distribution of the 12-15 transcript was found in maize leaves. ORF proteins encoded by both 12-15 and AY104898 were expressed in E. coli, and antisera were raised. The antibodies interacted with a protein of similar to 38 kDa in leaf extracts, as would be expected based on the size of the AY104898-encoded ORF. Neither expressed protein bound MCDV virions in virus overlay or in vitro pull-down assays. These results were similar to those found for the Arabidopsis Turnip crinkle virus (TCV) interacting protein, which interacted with free TCV coat protein but not with the assembled virions. Current work is focused on identification of specific interactions between MCDV CP1 protein monomers in vitro.

We examined the effects of light on growth and development in the northern corn leaf blight pathogen, Setosphaeria turcica (anamorph = Exserohilum turcicum). Cultures grown in continuous white or blue light were arrested after the formation of conidiophores, whereas light-grown cultures exposed to darkness for at least 2 hr produced mature conidia. We exploited this requirement for darkness to identify genes specifically upregulated after induction of synchronous conidiation. Sequence analysis of cDNA subtraction libraries revealed several candidate genes with putative regulatory functions, and quantitative PCR confirmed that those genes were preferentially expressed after cultures were shifted to darkness. Twelve of the dark-induced ESTs exhibit high translated similarity to proteins involved in signaling cascades or gene regulation, including three classes of monomeric G-proteins, various kinases and receptors, and a transcription factor. Of these, we are particularly interested in a cryptochrome-like blue-light receptor, EtCry1. Homologs of EtCry1 appear to be limited to genomes of pathogenic fungi. Results of efforts to functionally characterize EtCry1 and other candidate genes in S. turcica and their respective homologs in Magnaporthe grisea and Gibberella zeae will be presented.

Previous laboratory research demonstrated that NVS suppressed Heterodera glycines. This study aimed to identify factors that could potentially influence the efficacy of NVS as a H. glycines management tool. NVS was applied to soil microcosms, and nematode survival and changes in sand solution pH and ammonia were measured. Microbes associated with NVS appeared not to be responsible for the nematode suppressiveness of the amendment; there was no difference in nematode suppression between sterilized and unsterilized NVS. Alkaline-stabilization of biosolids was necessary to achieve nematode suppression. Biosolids applied at rates ranging from 1 to 3% dry w/w did not suppress H. glycines to the same level as equivalent amounts of NVS. Sand solution pH levels after biosolid application ranged from 7.7 to 8.6. The ability of NVS from different geographical sources to suppress nematodes was related to sand solution pH levels. NVS sources applied at 2% dry w/w resulting in sand solution pH levels above 10.0 reduced H. glycines survival 94% or more.

In many cases analyses have been limited in the number of representatives sampled from specific groups. The degree of intraspecific genome diversity remains in question, and it is possible that a single model genome may have limited utility for identifying genes in related members of the species or genus. Genes of particular interest for crop-plant improvement are disease resistance genes that are harbored by wild relatives of modern cultivated crops. These genes are evolutionarily dynamic and under selective pressure by a broad range of pathogenic organisms. Using resistance gene analogs as models for resistance gene evolution, intraspecific genome comparisons were made among populations of wild diploid wheat (Aegilops tauschii). We observed deletion haplotypes occurring frequently and independently in the genome, where total loss of gene complements is a common yet overlooked form of allelic variation. Haplotypes are correlated with species distribution and are without adaptive value in alternate environments. We address the consequences of deletion haplotypes on genome restructuring and resistance gene evolution.

In order to develop long-term strategies to combat this disease, we are focusing on proteins expressed in germinating spores and secreted by the fungus into the infection court prior to penetration. Our objectives in this study were to identify and characterize proteins expressed and secreted by P. pachyrhizi urediniospores during germination. To accomplish this, we extracted and analyzed both total proteins and a cell wall protein fraction from P. pachyrhizi urediniospores germinated on water for 18 hours. Trypsindigested two-dimensional gel electrophoresis spots were peptide fingerprinted and sequenced using Matrix-Assisted Laser Desorption/Ionization mass spectrometry with automated tandem time of flight fragmentation of selected ions. Proteins identified from the resulting peptide sequences by database searches within a confidence interval greater than or equal to 95 percent were evaluated and placed into functional categories. Proteins with putative roles in fungal infection and virulence were further identified from extracellular fractions washed from germinating urediniospores.

The heterothallic S. avenae f. sp. avenaria (Saa) would attack oats only, and the homothallic S. avenae f. sp. triticea (Sat1) would infect wheat and other cereals. Sequences of the noncoding internal transcribed spacer (ITS) region of the nuclear rDNA repeat and full-length glyceraldehyde-3-phosphate dehydrogenase, beta-glucosidase and beta-tubulin genes from these two formae speciales isolates were compared. In two S. avenae isolates (Sa38-1 and Sa39-2) from Polish oats these sequences were characteristic of Sat1. On the contrary, in two S. avenae isolates from wheat (ATCC58582 and ATCC58583), previously named Sat1, the sequences were characteristic of Saa. It appears that S. avenae formae speciales Saa and Sat1 can be appropriately identified by molecular methods, but not by asexual spore morphology or host specificity.

The complete arom gene and its transcript from R. solani, anastomosis group 3 has been characterized. The gene consists of 5,323 base pairs including five introns. The upstream sequence has a GC box, and two GTATTAGA repeats. The largest isolated arom transcript is 5,108 nucleotides long. It contains an open reading frame of 4857 bases, coding for a putative 1618-residue pentafunctional AROM protein. A Kozak sequence (GCGCCATGG) is present between +127 and +135 bases. The 5'-end of the transcript includes two nucleotides (UA) that are not found in the genomic sequence. Size and sequence heterogeneity were observed at both 5'- and 3'-ends of the mRNA. Northern blot and suppression subtractive hybridization analyses showed that presence of a low amount of quinate, inducer of the quinate pathway, resulted in increased levels of arom mRNA, consistent with the compensation effect observed in ascomycetes. Phylogenetic analyses of the putative R. solani AROM protein with sixteen AROM proteins belonging to three groups of ascomycetes and two AROM proteins from other basidiomycetes correlated with the widely accepted fungal systematics schemes.

To elucidate the mechnisms of pathogenicity and biotrophic,, life style of this rust fungus, a whole genome sequencing project has been recently initiated. Construction of full-length cDNA libraries from different stages of the fungus and generation of expressed sequence tags (ESTs) are part of the project for gene annotation and functional characterization. Total RNA was isolated from urediniospores, germinated urediniospores, and teliospores. cDNA libraries were constructed using SMART cDNA construction methodology (Clontech) and Gateway cloning system (Invitrogen). Analysis of 196 random clones showed that the average insert size is approximately 1.5 kb, with a range from 0.3 kb to 4.2 kb. Sequence analysis of these clones indicated that 95% of the inserts were full length, based on the presence of an ATG start codon within 100 bp of the 5' end. Large-scale sequencing of these cDNA libraries is underway and the results of EST analysis will be presented.

Because of inability to culture phytoplasmas in artificial media, recent research has emphasized the study of genes and their products to gain greater understanding of these microbes. We cloned and analyzed a CPh phytoplasma DNA locus containing three full-length potential coding sequences (open reading frames, ORFs) encoding NusA and two hypothetical proteins, respectively, and two partial ORFs encoding Small protein B and If2, respectively. The present work focused on NusA, a protein involved in transcription elongation, termination, and anti-termination. The NusA protein from CPh phytoplasma contains three conserved RNA-binding domains (S1, Kh1, and Kh2) typical of NusA from other organisms. We carried out a phylogenetic analysis of each domain separately. The topologies of the phylogenetic trees indicated the evolutionary history of each domain among firmicutes.

While not all the causal agents of the disease have been identified, plant-parasitic nematode densities are often high in vineyard replant soils. This disease can be controlled by fumigation with methyl bromide. When nematodes are known to be the predominant pest, fumigation with 1,3-dichloropropene (1,3-D), alone or in combination with chloropicrin, can control replant disorder. Use of methyl bromide has been phased out, except for Critical Use Exemptions (CUE) or Quarantine/Preshipment (QPS) applications. Several field trials were conducted in fields following the removal of 60+ year-old vineyards. Treatments included combinations of registered and experimental fumigants, fallowing up to three years, cover crop, and resistant varieties. Nematode population density, plant vegetative growth, and berry yield were recorded up to six years after planting. The predominant nematodes present were Meloidogyne spp. and Tylenchulus semipenetrans. The benefit of multi-year fallow varied with nematode genus. Fumigation provided excellent control of nematodes. None of the rootstocks were resistant to both nematode genera. Differences in plant growth did not always result in differences in yield. Results for the combinations of treatments over time will be presented.

This separation technique supports high throughput analysis for molecular procedures, to determine identity and relationships based on DNA differences. We have used Simple Sequence Repeat (SSR) markers in Theobroma cacao to identify germplasm in tropical collections, to demonstrate the limited genetic diversity of some collections, and to examine origins of accessions. SSR analysis is a straightforward procedure, and results are easily scored with ACE. However, generating markers by Amplified Fragment Length Polymorphism (AFLP) and analysis of results by ACE, are significantly more involved. Using AFLP, which requires no prior sequence information, we have successfully differentiated species, subspecies and populations of Erythroxylum coca. AFLP of fungal plant pathogens has demonstrated vegetative compatibility groups in Sclerotinia homoeocarpa and revealed population structure in Ophiosphaerella agrostis and in the Stemphylium species group. Issues in interpretation of AFLP analysis will be discussed.

Twelve genes required for trichothecene biosynthesis in Fusarium are clustered within a 26-kb segment of DNA. However, several other biosynthetic and regulatory genes are located elsewhere in the genome. While many of the gene functions have been determined by mutational disruption, a few have been elucidated by a transgenic expression system. The regulation of trichothecene biosynthesis is not well understood. Two genes, Tri10 and Tri6, required for Tri gene expression and a third gene, Tri15, required for suppression of these genes, have been identified. Tri6 encodes a transcriptional factor that binds to specific nucleotide motifs within the promoters of other Tri genes, while Tri10 and Tri15 encode proteins whose method of regulation of gene expression is not known. Since trichothecene production by F. graminearum is necessary for virulence on wheat, elucidation of factors that regulate this production may lead to novel methods for the control of wheat head blight.

Results of a genetic analysis indicate there are multiple genes controlling transmission phenotype that act in an additive manner. One or more tightly linked genes regulate the transmission of luteoviruses and poleroviruses, however, individual aphid clones can transmit each virus independently, demonstrating some genes are unique for each virus genera. The nonvector parent has both gut and salivary gland associated barriers to virus transmission. These tissue-specific barriers were separated in some of the F2 hybrids examined. One F2 clone possesses a gut barrier to transmission, whereas in other clones, virus is either prevented from entering the salivary gland or is inactivated in the hemolymph. To investigate the involvement of hemolymph factors in the transmission of luteovirus, real time RT-PCR was used to quantify the retention of BYDV over time in vector and nonvector aphids. BYDV was retained for over two weeks regardless of vector status, indicating virion degradation cannot explain the loss of transmission.

A total of 111 ascospore progeny were analyzed for segregation in 237 loci. Genetic markers consisted of SNPs (detected as dCAPs, n = 86 or CAPs, n = 47), AFLPs (n = 71), SSRs (n = 27), and six other markers. While 213 markers exhibited Mendelian inheritance, segregation distortion was observed for 17 markers at four genomic locations. A linkage map was generated using JoinMap 3.0 and a LOD threshold value of 4.0. Eleven linkage groups were obtained, covering 1154 cM and anchoring 99.8% of the sequence assembly. All linkage groups and anchored supercontigs were assembled into four chromosomes, leaving only 11 smaller supercontigs (76,055 bp total) of the nuclear DNA not anchored.

Of particular interest are the differing factors inherent in the hard, red spring wheat of North Dakota and Minnesota in relation to the soft, red winter wheat grown in Indiana and Ohio. By testing newly available microsatellites in gene coding regions, it may be possible to ascertain if microsatellite analysis is adequate for determining genetic differentiation. If so, subtle population differentiations previously unrecognized could be elucidated. In preliminary tests of seven microsatellites, two to three alleles per locus were generally seen, most with little to no genetic variation detected between potential subpopulations. However, allele frequencies at two microsatellite loci were sufficiently different statistically to warrant additional experimentation. Further analyses with these microsatellites may help to test the effect of population structure on pathogenic differentiation, and to estimate the levels of migration between populations on hard spring versus soft winter wheat in the central United States.

Its genome is comprised of three single-stranded RNAs, designated alpha, beta, and gamma. A "band-aid" method was developed a number of years ago for generating full-length cDNA clones of BSMV from which infectious RNA could be transcribed. Since then, the ability to transcribe infectious RNA from such clones has led to a variety of studies incorporating a reverse genetics approach to the investigation of viral properties including pathogenicity, virulence, movement, and seed transmission. We have now used an alternative PCR-based cloning procedure to generate infectious clones of a white leaf strain of BSMV designated CV36. Extreme bleaching of infected leaves results in a dramatic white leaf symptom in infected barley that is quite different from the typical symptoms induced by BSMV. Sequences of full-length clones for each of the genomic RNAs are being determined and the clones characterized via infectivity, recombination, and mutation analyses to identify the viral sequence responsible for this distinctive phenotype.

Pantoea spp. were obtained from both the gut and the exterior of southern green stink bugs (SGSB) with similar frequency from the head and thorax compared to the abdomen and legs. Water washings from live stink bugs (2 ml sterile water per insect) frequently contained sufficient bacteria to cause seed rot when a needle puncture into the boll was made through a drop of wash water placed on the surface. The majority of female SGSB collected by black light traps in July, September, and October near cotton fields in the Brazos River Valley in Texas yielded seed-rotting bacteria. Most of the pathogenic bacterial isolates belonged to the Enterobacteriaceae family. Yellow isolates identified as Pantoea spp. had fatty acid profiles most similar to those of Pantoea, Cedecea, or Yersinia species, while white isolates had profiles most similar to those of Citrobacter, Enterobacter, Kluyvera, or Klebsiella spp. Two species of the Pseudomoniaceae family, Flavimonas oryzihabitans and Pseudomonas pudita, caused seed rot and were found in all three SGSB collections. All of these bacteria caused complete rot of 10- to 14-day-old locules of Deltapine 458 B/RR within 7 days of introduction through puncture wounds. The presence of seed-rotting bacteria on stink bugs may facilitate the spread and inoculation of bacterial pathogens.

To aid in development of disease control strategies, it is important to understand the structure and dynamics of A. tumefaciens populations in soil. Here we report on the seasonal variation of pathogenic and non-pathogenic A. tumefaciens strains in soil around both diseased and healthy trees using culture based and culture-independent methods. Soil samples were collected monthly and A. tumefaciens was enumerated on 1A containing tellurite with populations ranging from 10 super(4) to 10 super(6) CFU/g over the sample period. Using Ti-plasmid and chromosomal-specific primers, randomly selected colonies on IA-tellurite were subjected to PCR based screening to identify virulent and avirulent strains. Ti-plasmid containing isolates represented less than 1% of the A. tumefaciens population. By combining direct soil-DNA extraction with real time PCR, populations of both virulent and avirulent cells were estimated with limits of detection at 20 CFU/g soil. The use of culture independent population estimates versus estimates by dilution plating on selective media in the examination of A. tumefaciens ecology under field conditions will be discussed.

Cotton/corn rotations are common in South Texas where reduced tillage frequently results in long-term residence of corncobs on soil surfaces. Corncobs are colonized by A. flavus either prior to harvest or in the soil. This study sought to determine the potential of corncobs as sources of inoculum for cotton and corn in South Texas. Corncob and soil samples were collected from 24 fields extending from Calhoun and Victoria Counties in the north to the Rio Grande Valley during the planting seasons of 2001 and 2002. In addition, A. flavus communities in corncobs and soil were contrasted in two fields on a biweekly basis for one season. Results indicate that corncobs might be an important source of A. flavus inoculum for cotton and corn crops. Corncobs from the previous season contained, on average, over 100 times more A. flavus propagules than soil from the same field, and two-year old corncobs still retained 50 times more propagules than soil. There were no significant differences in incidences of A. flavus strain S between corncobs and soil. The quantity of A. flavus in corncobs decreases with corncob age.

This research was conducted to determine the efficacy of ADBAC on suppression of P. vaccinii in laboratory conditions. The efficacy of ADBAC for inhibition of fungal growth was evaluated by using in-vitro liquid medium, disc diffusion assays, and detached cranberry fruits at concentrations of 0.01 to 100% of the standard formulation and incubated at 25 degree C for 7 days. Reduction of colony diameter and mycelial dry weight of P. vaccinii was detected at 100% concentration. Complete inhibition of fungal growth was observed at 100% concentration after 7 days of incubation. At 0.01 to 10% concentration, no reduction of fungal growth and mycelial dry weight was observed when compared with the unamended controls. On detached fruit studies, complete inhibition of fungal growth was also achieved with 100% concentration of ADBAC. None of the ADBAC concentrations in the range of 0.01 to 10% reduced fungal growth relative to the control cranberry fruits which were inoculated with fungus. These results suggest that ADBAC has an inhibitory effect on growth and development of the P. vaccinii.

In countries where cocoa is an important cash crop for small farmers, Integrated Pest Management (IPM) strategies that are reliable and economically viable are seen as the best approach. Until better cacao varieties that are resistant to pests and diseases are available for farmers, farming practices, phyto-sanitation and use of chemicals are some of the strategies adopted, however, with limited success. In collaboration with the National Research Institutes, an Industry-USDA-ARS sponsored global initiative on IPM has been initiated to address some of the problems in Latin America, Africa and Asia. The use of environmentally safe control agents, biological control and the rational use of insecticides and fungicides are the basis of this new joint program. Progress has been made in developing networks in countries affected by an insect, cocoa pod borer and the three fungal diseases, witches' broom, frosty pod rot and black pod rot. Both basic and applied research, setting-up field trials and training both scientific personnel and farmers in farmer field schools are in progress.

Southern pine (moderately resistant to decay) and red Oak (resistant to decay) were inoculated with a 7-day culture of Gloeophyllum tracheum and Irpex lacteus (1 x 10 super(5) spores/ml) by injecting fungal spores into pieces of wood and incubating at 25 degree C for 30 days. Subsequent to incubation, the pieces of wood were exposed to radio frequency (RF) in an industrial 40 KW dielectric oven at the temperatures between 60-70 degree C for 2 min. Over 2,520 isolations attempts from 840 lesions were made from inoculated and control wood species. The fungi were recovered from all the control wood species (un-inoculated) but not from RF-treated wood pieces. RF treatment resulted in complete inhibition of the fungus. Moisture content loss (<1%) was noted after wood had been exposed to RF treatment compared to the untreated control. Moisture content may be an important factor to consider with radio frequency treatments. RF treatment can, therefore potentially provide an effective and rapid quarantine treatment as an alternative to MB for certain pathogen wood combinations.

A case study is presented for using multiple approaches to analyse the potential for reforestation and improving livelihoods of small farmers through the adoption of agroforestry systems in the Calakmul Biosphere Reserve in Campeche, Mexico. Specifically, the results from a participatory research project are combined with revealed preference analysis of a household survey to analyse past adoption decisions and preferences, identify limitations, test and evaluate alternatives, and evaluate methods for risk reduction. The participatory research trials suggest that continuous intercropping and line cleaning are equally effective for tree growth, while continuous cropping during the first years offers the additional advantage of early returns to investments through crop production. Farmer participation in the research process, planning of production systems, and annual evaluations, assisted farmers and researchers in identifying limitations, testing and evaluating alternatives, and improving the viability and sustainability of systems. The revealed preference analysis provides insights as to which households are most likely to initially adopt agroforestry systems developed through the participatory research trials. In general, households that originated from the Yucatan Peninsula with more education, more experience both in age of the head of household and technical and project experience, higher incomes, and those that had cleared more forestland were more likely to have experimented with agroforestry systems in the past.

For more sustainable (durable) genetic resistance, combining more than one gene effective against an individual pathogen is desired to: i) acquire pyramided resistance against a prominent pathotype; ii) obtain broad resistance against a range of pathotypes; iii) retain defeated resistance genes; iv) combine different mechanisms of resistance, and v) increase levels of partial resistance by combining genes (QTL) with additive effects. Examples above for combining genes for improved and more durable resistance against bacterial, fungal, or viral pathogens in bean will be discussed. The use of marker-assisted selection to achieve resistance gene combinations will be emphasized.

An indica cultivar Zhe733 is resistant and a tropical japonica low phytic acid Kaybonnet mutant lpa1-1 and cultivar C101A51 are susceptible to M. grisea race IE1k (TM2). To identify the resistance genes in Zhe733, 256 F sub(2) individuals from a cross of Zhe733 and C101A51 were inoculated with TM2. A ratio of 15:1 resistant to susceptible indicated the presence of two dominant resistance genes in Zhe733. To tag the resistance loci, 353 F sub(10-11) recombinant inbred lines from a cross of Zhe733 and Kaybonnet lpa1-1, were inoculated with IE1K. A 3:1 ratio of resistant to susceptible confirmed the presence of two dominant resistance genes in Zhe733. Of the 162 SSR markers used to characterize Zhe733 and Kaybonnet lpa1-1, 126 showed polymorphism and these were used for bulked segregant analysis on 10 susceptible and 10 resistant plants. The progress on tagging and fine mapping of the genes will be presented.

However, pear production is often hampered by bacterial, fungal, and viral diseases. As part of our program aimed at improving resistance of pear crops to diseases via genetic engineering, we studied the influence of medium composition and growth regulators on adventitious shoot formation from in vitro propagated leaf explants of two popular commercial pear cultivars, 'Onward' and 'Old Home'. Among three basal media (NN69, WPM, and C) tested, NN69 appeared to be the most suitable for promoting shoot regeneration. The cytokinin thidiazuron was much more effective than 6-benzylaminopurine in promoting shoot regeneration in both cultivars. The effect of two auxins, indole-3-butyric acid and alpha-naphthalene acetic acid, was genotype-dependent. Under optimal conditions, the regeneration frequency reached 90% and 100% for 'Onward' and 'Old Home', respectively. A comparative structural analysis revealed that shoot regeneration from 'Onward' leaf explants essentially occurred via direct organogenesis and that shoot regeneration from 'Old Home' leaf explants followed an indirect organogenesis pathway. The optimal regeneration conditions established in this study were successfully applied to Agrobacterium-mediated genetic transformation of the two pear cultivars.

Resistance Bdv3, derived from a related wheatgrass Thinopyrum intermedium, was integrated into wheat. This YDV resistance provides complete resistance to Cereal Yellow Dwarf Virus (CYDV). Resistance, however, does not inhibit viral replication. Cellular analyses have indicated that this resistance to CYDV is due to an inhibition or block of systemic virus movement. Unexpectedly, these data also demonstrated a negative effect on the feeding behavior of the aphid vector. Th. intermedium-derived CYDV resistance appears to act at two levels; aphid feeding and virus spread.

This bean accession from Bolivia is resistant to all but one of the 90 races of the bean rust pathogen that have been identified at Beltsville, Maryland. The Andean beans "Early Gallatin", which has the Ur-4 rust resistance gene, and "Golden Gate Wax", which has Ur-6, are resistant to only 30 and 22 of the same 90 races, respectively. PI 260418 is susceptible only one race collected from an Andean bean in the state of Colorado. The large-seeded (>60 g/100 seeds), photoperiod-sensitive PI 260418 was crossed with bean "Pinto 114", a Middle American bean that is susceptible to 89 of the 90 races at Beltsville. Inheritance and segregation analysis based on the reaction of the parents, F1, F2, and backcross populations to 14 races of the rust pathogen, reveal that an unlinked locus in PI 260418, different from Ur-4, confers monogenic resistance to the races of U. appendiculatus used in this study. When PI 260418 was crossed with Early Gallatin to determine genetic relationship among these two rust resistance sources, recovery of susceptible individuals in F2 populations confirmed that PI 260418 and Early Gallatin possess different rust resistance genes at unlinked loci.

Transformation of wheat is slow and inefficient, and isolation of genes is greatly complicated by the large genome size (16,000Mbp) and hexaploidy. Development of a virus-induced gene silencing system for wheat should provide a tool for the functional identification and analysis of genes that circumvents many of these obstacles. A VIGS system for wheat based on Barley stripe mosaic virus will be described in this talk. Additionally, its use to probe the molecular genetics of several wheat disease resistance pathways will be discussed.

Mycotoxin contamination is a chronic problem in agriculture, especially in cereal grains infected with certain species of Aspergillus, Claviceps/Epichloe, Fusarium, and Penicillium. Mycotoxin contamination also is a potential hazard in the plant pathology laboratory. Safe handling of mycotoxins in research laboratories requires development and enforcement of guidelines that cover routine handling and decontamination procedures, as well as medical monitoring of laboratory personnel. Safeguarding human health is a major responsibility in the mycotoxin research laboratory.

We are utilizing cDNA and Affymetrix microarrays to identify Glycine max transcripts responding to microbes and pests. We have completed a study of the Psuedomonas syringae induced hypersensitive defense response enabling the comparison of defense responses not involving the HR, such as defense against agronomically important diseases for which single gene resistance does not occur, like Sclerotinia Stem Rot and Fusarium solani induced Sudden Death Syndrome. Defense requiring input from multiple genes (quantitative trait loci, or QTLs) are difficult to genetically characterize by traditional breeding methods and microarray analyses offer an increased chance that some of the genes underlying QTLs will be identified and tagged for use in breeding programs. Sequence information from genes that show differential expression specific to resistant lines is being used to design PCR-based molecular markers. These markers will be used to determine if a given gene maps in tight association with known QTLs for resistance. The sequence information also allows for design of gene-specific primers to monitor gene expression in other soybean-microbe interactions to determine if a given gene is playing a role in generic defense or if its expression is disease specific.

Investigating Pi-ta-mediated signaling pathways will facilitate a better understanding of the molecular mechanisms of disease resistance. In this study, a Pi-ta containing U.S. cultivar Katy was treated with fast neutrons. A total of 14,000 M1 random panicles was collected and 7-10 M2 seedlings of each M1 was used for inoculating M. grisea race IC-17 (ZN61) containing AVR-Pita. The initial screenings identified 170 susceptible plants and only 44 mutant plants were confirmed to be susceptible at each generation to M6. Differential disease reactions were observed among 44 mutants. Based on differential disease reaction, nineteen plants were selected for the confirmation of their origin using 10 additional Simple sequence repeat (SSR) markers. Five of 19 mutants were confirmed to possess SSR profiles identical to the parent Katy and these five plants were further verified using 20 additional SSR markers. Preliminary analysis using a marker for Pi-ta suggests that three mutants lack the resistant Pi-ta allele and two mutants contain the resistant Pi-ta alleles. Progress on the genetic and molecular analysis of these Pi-ta susceptible mutants and Pi-ta-mediated signal recognition will be presented.

For the wheat industry to remain competitive, these programs must integrate new technologies into conventional breeding efforts. USDA-ARS Regional Genotyping Laboratories for wheat and other small grains were established to assist programs in the practical use of marker assisted selection (MAS) through high-throughput DNA extraction and marker screening procedures. In addition, a consortium of public wheat breeding and genetics programs was formed in 2001 that has worked to introgress more than 23 disease resistance genes and 21 quality-related gene variants into adapted wheat parents of different market classes. As information from the wheat EST project and the rice genome sequence have become available, they been used to target new markers linked to agronomically important wheat genes. Strategies for deployment of multiple disease resistance genes in forward breeding programs using these resources will be presented.

This research was to identify resistance genes in response to leaf spot disease using miccroarray and real-time PCR. To identify transcripts involved in disease resistance, we studied the gene expression profiles in two peanut genotypes, resistant or susceptible to leaf spot disease, using cDNA microarray containing 384 unigenes selected from two EST (expressed sequenced tag) cDNA libraries challenged by abiotic and biotic stresses. A total of 112 spots representing 56 genes in several functional categories were detected as up-regulated genes (Log2 ratio > 1). Seventeen of the top 20 genes, each matching gene with known function in GenBank, were selected for validation of their expression levels using real-time PCR. These two peanut genotypes were also used to study the functional analysis of these genes and possible link of these genes to the disease resistance trait. Microarray technology and real-time PCR were used for comparison of gene expression. The selected genes identified by microarray analysis were validated by real-time PCR. These genes were more highly expressed in the resistant genotype as a result of response to the challenge of C. personatum than in the susceptible genotype. Further investigations are needed to characterize each of these genes in disease resistance. Gene probes could then be developed for application in breeding programs for marker-assisted selection.

To date, efforts to engineer improved strains have focused mainly on genes involved in the synthesis of antifungal metabolites The expression of these genes is dictated largely by environmental stimuli including nutrient availability, and one focus of research has been to uncouple this dependence by overexpressing activators of gene expression, inactivating repressers, or placing the biosynthetic genes under the control of unregulated promoters. Alternatively, biosynthetic genes have been transferred to enhance the performance of recipient strains with other desirable attributes. Efforts to improve strain competitiveness have been directed mainly toward genes involved in nutrient acquisition and phenotypic plasticity within introduced populations. While the commercial use of unmodified biocontrol agents is slowly gaining acceptance, the release of recombinant strains remains controversial. Concerns focus on the stability and fitness of the recombinants and on the potential for horizontal gene transfer and deleterious nontarget effects. Data from controlled field releases are needed in order to critically assess the relative performance and environmental impact of recombinant and unmodified strains. Such studies will be greatly facilitated by sensitive and highly specific techniques that have been developed to detect microorganisms and bioactive metabolites produced in natural habitats.

Blueberry fruit produce aromatic volatiles including trans-2-hexenal that may confer resistance to Anthracnose fruit rot, an important postharvest disease caused by Colletotrichum acutatum. To test the hypothesis that aromatic volatiles in blueberry fruit may be associated with postharvest disease resistance, we compared volatile concentrations in headspace extracts of C. acutatum-inoculated and non-inoculated blueberry fruit stored 0 to 5 days from 10 cultivars having a wide range of resistance to anthracnose. While volatile concentrations including that of trans-2-hexenal varied amongst the cultivars with early ripening cultivars generally having higher volatile concentrations than later ripening cultivars, no consistent correlation was detected amongst cultivars with respect to anthracnose resistance. Aromatic volatiles decreased rapidly in most cultivars during storage, and exposure to anthracnose infection prior to storage had no effect on either volatile profiles or concentrations throughout storage. The results suggest that aromatic volatiles in blueberry fruit are not inducible by C. acutatum infection and do not contribute to disease resistance against Anthracnose fruit rot.

Morphological identification can be supported by host differential tests and molecular techniques. Molecular techniques have been developed in order to distinguish species, races, and biotypes, as well as study genetic variability and phylogenetic relationships. Enzyme phenotypes in phytoparasitic nematodes have been studied for 35 years. Isozyme phenotypes have been used to comparatively study several nematode genera; however the genus Meloidogyne has received the most extensive investigations. Early research provided multiple enzyme phenotypes for four Meloidogyne species. The number of characterized species has grown providing a practical method for identification. The advent of miniaturized polyacrylamide gels allowed the phenotype of a single female to be determined. The PhastSystem (GE Healthcare) has automated the electrophoretic procedure for very thin polyacrylamide gels. The use of esterase and malate dehydrogenase phenotypes can be used to distinguish the most common Meloidogyne species. However during routine use of this technique for identification of field samples, phenotypes not previously described are commonly found. JF - Phytopathology AU - Church, G T AD - USDA-ARS, US, Ft.

This species is comprised of three infraspecific groups, each with a distinct habitat association. Group 1 is found on terrestrial grasses, G2 in "wet and shady" environments, and G3 is found in coastal salt marshes on cordgrass species of the genus Spartina. In the Southeastern United States (USA), San Francisco Bay, California, and along the coast of United Kingdom, G3 C. purpurea has reached epidemic levels of infection on Spartina spp. However, on invasive Spartina alterniflora in Willapa Bay, Washington, the pathogen is relatively rare. Spanina alterniflora is rapidly expanding through the Willapa Bay estuary, predominantly by seed recruitment, and is currently the focus of an integrated pest management program which includes the use of chemical, mechanical and biological control. A population genetic analysis of C. purpurea in Willapa Bay, using random amplified polymorphic DNA markers shows that all three infraspecific groups, G1, G2, and G3 are present in the estuary. Low genetic diversity within G3 populations suggests that this pathogen may have been recently introduced to the region. Infection rates of G3 on S. alterniflora ranged from 0 to 7% from 2001 to 2003. Neighbor-joining analysis of amplified fragment length polymorphism markers suggests that G3 C. purpurea in Washington is most closely related to Southwestern USA G3 C. purpurea. Pairwise comparisons as part of an AMOVA showed that Willapa Bay isolates are different from all other geographic regions except Argentina. The low incidence of the pathogen in Washington may be due, in part, to a G3 ergot population that is not well adapted to Northwest environmental conditions.

The succulent thick stems of 'd'Anjou' pear are prone to colonization by these fungi. We isolated bacteria and yeasts from pear and apple fruits and screened them for their ability to colonize pear stem tissue. Populations of the best bacterial and yeasts colonizers increased by more than 2 log units within 3 d at 24 degree C. They were then evaluated in cold storage at 1 degree C for their ability to prevent infection of pear stems by a very aggressive strain of P. expansum, and a weakly pathogenic strain of a Penicillum spp. isolated from a pear stem. A few isolates reduced stem-end decay and the biocontrol potential of some of these isolates has been confirmed in subsequent tests. Two bacteria were found to promote fungal infection of the stem and subsequent fruit decay by both pathogens. The abundance of the decay promoting bacteria in some years may be responsible for the high incidence of stem-end decay in those years.

For example, accurate detection and identification of Phytophthora ramorum is essential in preventing the spread of that pathogen. Early detection of Phakopsora pachyrhizi is important in tracking the movement of that disease and making appropriate management decisions. Accurate identification of pathogens on plants and plant products in international trade is essential in preventing the introduction and spread of invasive species. The ability to accurately detect and identify plant pathogens, especially exotic and potential invasive species, relies first on a sound and robust systematics knowledge base of plant pests on a global scale. Challenges include the reduced support for systematics worldwide resulting in inadequate and incomplete knowledge of fungal diversity. This in turn results in a lack of detection and identification tools for diagnosticians, extension agents, regulatory scientists, and others making identifications and disease diagnoses which are important in order to minimize losses due to introduced pathogens. Other challenges include availability of literature, lack of identification aids, need for appropriate equipment, and communication issues. National and international networks in support of detection and identification using standardized protocols need to be strengthened and supported in order to meet these identification challenges.

This study was initiated to isolate potential biocontrol bacteria for use against A. flavus from almond samples obtained during the growing season. Bacteria were screened for activity against a nor mutant strain of A. flavus in co-culture assays using solid and liquid media. This mutant accumulates the aflatoxin precursor norsolorinic acid, a bright orange pigment, under aflatoxigenic conditions. This feature was used to visually indicate the effect of bacterial strains in co-culture on aflatoxin biosynthesis. Following initial screening, 338 bacterial isolates from almond blossoms and immature and mature almonds were selected for further characterization. Of these, 195 isolates inhibited A. flavus growth, and an additional 33 isolates inhibited aflatoxin production. Bacterial strains were identified using 16S rDNA sequence analysis. Based on their origin and antagonistic properties, these strains demonstrate the potential for development of bacteria from naturally occurring populations as biocontrol agents to control mycotoxigenic fungi.

The next 70 years was dominated by reports of what insect vectored which virus to what plant, but a small innovative ensemble of scientists quietly revolutionized our understanding of the relationships between plant viruses and insect vectors. Unlike animal viruses, most plant viruses did not infect their insect vectors, nor was transmission explained by simple mouthpart contamination or the flying needle analogy. Two seminal concepts emerged, circulative versus stylet borne transmission and virus persistence versus nonpersistence. These discoveries coupled with newly developed in vitro transmission assays and later ultrastructual studies led to an understanding of the virus-vector interactions associated with virus attachment to vectors or circulation through insects. Genetic manipulation of viruses has led to the discovery of specific features of the virus influencing vector-specificity such as, nonstructural helper factors that regulate the attachment of some viruses to the insect stylet and the role of the virus structural proteins in vector tissue recognition. The insect remains a "gray" box, but one being illuminated by a developing insect genomic database. Discoveries on what the insects are contributing to specific virus-insect interactions will play a major role in future research.

Available to the research community are a vast resource of fungal ESTs from a wide range of genomes and expression conditions. A visual gene-mining method was developed to identify genes expressed based on attributes associated with cDNA libraries such as developmental stage, tissue-type, or other specialized conditions. Visualized EST patterns of expression from fungal genomes were compared to genome sequence structure of reference fungal genomes, mainly those available as pathogens of cereal crops. The testing hypothesis was to look at gene expression clustering, select genes, and test their relative positions in genomes using the few representatives of fully sequenced genome sets. Close attention was paid to those expressed sequences which could be placed into clustered coordinates on the physical genome. A screen was also conducted for sequences associated with secondary metabolism profiles, as evidence in some toxigenic or pathogenic species suggests clustering, or co-localization of genes associated with coordinated gene expression. Using the visual gene-mining method, other gene clusters are in process of being identified to help understand gene expression, or uncover new clusters for study, within the fungi.

In vitro assays showed that some Streptomyces 99-60 culture broth filtrates contained a toxic compound(s) that reduced M. incognita egg hatch and inhibited activity of second-stage juveniles. In a greenhouse study, application of Streptomyces 99-60 to soil and to cantaloupe seedling roots did not reduce M. incognita egg populations, and combinations of Streptomyces 99-60 with NVS did not enhance NVS activity. In the same greenhouse tests, NVS was applied at two rates: 1% and 3% dry weight amendment/dry weight soil. The 3% NVS application significantly (P less than or equal to 0.01) reduced numbers of M. incognita eggs on cantaloupe roots compared to all other treatments. The 3% NVS application rate also resulted in the highest accumulation of ammonia in soil and elevation in pH. Efficacy of NVS against M. incognita was associated with the generation of high ammonia levels in soil; egg numbers were not affected when soil was amended with calcium hydroxide to increase pH to the same levels as those recorded with NVS application.

We developed a multiplex diagnostic platform for (Xf) genetic analysis using a multi-locus simple sequence repeat (SSR) DNA marker system. This system employs a multiple fluorescent-labeled genotyping format analyzed by an ABI 3100 genetic analyzer. We combined this system with our rapid sample preparation protocol to create a high-throughput (Xf) pathogen diagnostic and genetic analysis. Genetic analyses of California's (Xf) populations were performed with this system by testing PD-associated (Xf) strains from four grape growing counties and ALSD-associated (Xf) strains from the San Joaquin Valley's almond growing regions. This pathogen detection system worked well for both plants (grape and almond) and insects (green sharpshooter and glassywinged sharpshooter). The system avoids the time-consuming bacterial isolation step and reduces the chance of sample loss due to contamination and culture difficulties. The sensitivity, specificity and ability to detect Xf polymorphism in plant and insect hosts make this system an ideal tool for studies of (Xf) genetics and epidemiological risk assessment analyses.

Quarantine restrictions limit the interstate movement of host nursery stock and related articles from infested areas in California, Oregon, and Washington. Therefore, an accurate detection system is needed to track the movement of the pathogen. A conventional PCR marker system based on the spacer region between the mitochondrially encoded genes COX1 and COX2 has been developed for detection of Phytophthora species associated with tree decline in areas known to have SOD. We have adapted this system for real-time PCR detection using both SYBR green and TaqMan technologies and are expanding it to include other species such as P. pseudosyringae and P. nemorosa, species commonly isolated from P. ramorum infested areas. Current data indicate that PCR inhibitors contribute to a lack of sensitivity with some PCR based detection systems. To clarify this we are comparing the efficiency of PCR amplification using DNA isolated with different high throughput extraction protocols and from plant species known to possess PCR inhibitors. This work will provide knowledge to enhance the reliability and sensitivity of molecular diagnostic methods for this pathogen and potentially numerous others.

An early detection system is being developed to enhance current safeguarding efforts to prevent further introduction of Rsr3b2. Latency associated with Rsr3b2 in geraniums required that a sensitive, reliable and rapid sampling and diagnostic strategy be developed to detect Rsr3b2 in asymptomatic plants. Commercially available filter devices were used to concentrate bacteria from water effluent collected from both laboratory-spiked samples and geraniums, which were inoculated with 20 microliters of either a 10 super(6 or 8) CPU/ml suspension of Rs and grown in scoria potting media in a secured growth room. Rs was detected in water effluent using Agdia ImmunoStrips for Rs. The methods for water collection, DNA extraction from filters and ImmunoStrips, and PCR detection will be presented. DNA was amplified using two sets of specific primers and dual-labeled probes in real-time PCR using a Cepheid Smart Cycler.

The objective of this study was to investigate the splash dispersal of Psc, and the resulting infection in coriander seedlings subsequent to a rain splash event. Splash was generated at a point source in the centre of a linear series of exposed Petri-dishes containing Kings B media, and the number of colony forming units (CFUs) counted at different distances from the point source. Droplets fell most frequently close to the inoculum source and seldom at distances >50 cm. The number of CFUs on each plate followed a similar pattern. More seedlings close to the source of inoculum became infected after splash was generated from a point source of Psc in the centre of a lawn of coriander seedlings, and incidence of infection showed a negative exponential decrease with distance from the source (R super(2) = 0.96). These results suggest rain splash plays an important role in the dispersal of Psc and the development of disease within fields of coriander during natural rain events or where overhead irrigation is used.

In addition to X. fastidiosa genotypic data, phenotype information, or the expression of genes, is equally important for understanding the epidemiology and the genetic of this pathogen. We examined the colony morphologies of strains of two X. fastidiosa genotypes isolated from ALSD-affected trees in California. Although significant variations occurred during more than 14 sub-culturing passages, the colony morphology associated with each genotype could be found among most strains. Best differentiations were in the early passage cultures. G-genotype strains were typically smooth with entire margin. Most of the A-genotype strains were "pit"-like, or umbonate with a smooth convex center and rough surface in the outskirt. Both A-genotype and G-genotype strains produced colony imprints or surface etchings on PWG medium, suggesting enzymatic depolymerization of gellan polysaccharide. Two candidate genes for gellan depolymerization were identified in silico. The colony morphology data in conjunction with PCR genotyping was used to survey genotype distribution in the central and southern San Joaquin Valley of California. We conclude that the two genotypes did not spread simultaneously.

Identifying and quantifying bacteria is useful when investigating the epidemiology of the pathogen and can have application in monitoring dispersal of live bacteria. In a series of experiments using field collected samples of wind-blow splash, dilution plating was compared with an established citrus canker SYBR Green real-time PCR method for detection from symptomatic tissues using universal primers VM3+4. Of 314 samples tested, 235 (75%) agreed on detection. False negatives using PCR were found in 75 (24%) of samples, all of which contained 3 to 863 bacteria/per ml detected by dilution plating. Only 4 samples (1%) were positive using PCR, but not by dilution plating. There was a positive linear relationship between the real-time PCR score and log number of living bacteria collected/ml (0 to 1.0 x 10 super(5), R super(2) = 0.72), although a large range of living bacteria/ml existed within each PCR category. No modification was made to the PCR protocol and no splash-sample concentrating procedures were performed. The results confirmed previous observations on the sensitivity of real-time PCR for detecting citrus canker bacteria (10 super(3)/ml). Research to improve detection via real-time PCR at low concentrations is ongoing.

For each host, replicate potted plants infected with Xf and noninoculated controls were maintained in screenhouses at two locations (Mendocino, Napa), and were assayed repeatedly from 2003-2004, by culturing and real-time PCR, to quantify seasonal Xf populations. Periwinkle, Himalayan blackberry, and California grapevine harbored Xf populations above the vector acquisition threshold at two of four sampling intervals (autumn and summer) at both locations, suggesting that the presence of these species in proximity to vineyards may increase the risk of PD. In contrast, the extremely low detection frequency of Xf in California blackberry and elderberry indicates that these hosts may add little risk of PD in adjacent vineyards; therefore, efforts expended in removing them may not be repaid with a reduction in disease incidence. The only Xf-positive plants detected in spring at both locations were periwinkle and Himalayan blackberry, suggesting that these invasives may contribute to long-term survival of Xf in areas with low overwinter survival of the vector.

Wind/splash was simulated to study the plume of splash dispersed bacteria downwind from infected trees using an electric fan to produce wind (approx. 0 [control], 4, 7 and 20 ms super(-1)) and overhead nozzles to simulate rain. Higher wind speeds dispersed more bacteria at all heights and distances sampled (at 1 m distance a mean of 2.7 x 10 super(3) and 4.0 x 10 super(5) bacteria were collected, and at 3 m distance, 0 and 9.4 x 10 super(2) bacteria were collected at 0 and 17 ms super(-1), respectively). A positive linear relationship existed between wind speed and quantity of bacteria collected (R super(2) = 0.81). A power law model fit the dispersal gradient at all wind speeds tested (R super(2) > 0.99). In further experiments the relationship between wind speed, height above ground and log total bacteria collected showed that the pattern of dispersal remained the same (linear, R super(2) = 0.83-0.95). The results indicate that the quantity of bacteria dispersed increase with wind speed but the plume of splash (vertical and horizontal) retained its overall pattern. The effect of wind speed on dispersal of Xac) is relevant where storms with strong winds can increase the quantity of wind blown inoculum.

We examined bacterial reproduction, disease impact on the host and mechanisms of infection. The bacteria pathogen underwent cell division every 84 minutes and ceased growth above 35 degree C. Plant mortality (94%) resulted from needle inoculation of stems with Psc, with the biomass of infected plants significantly reduced. High numbers of the pathogen (10 super(4) to 10 super(8) CFU g super(-1)) were isolated from tissues throughout plants one week after inoculation. Inoculation of seed resulted in some seedling infection (8%), and subsequent wounding did not significantly increase disease incidence or severity. Spray inoculation with Psc at concentrations >10 super(2) bacteria per ml caused infection, but 10 super(7) to 10 super(9) bacteria per ml caused greatest severity of disease. The results demonstrate the rapid onset and severity of plant damage resulting from infection, and suggest Psc is more readily dispersed in water splash than via seed, and that the bacteria do not appear to require a wound to infect the plant.

We tested the impact of four Pythium spp. on colonization of wheat roots by indigenous populations of 2,4-diacetylphloroglucinol (DAPG)-producing Pseudomonas fluorescens in Washington State suppressive soils. Soils were cycled to wheat (cv. Penawawa) to reactivate and increase indigenous populations of the DAPG producers to a density greater than 10 super(5) CFU/g fresh root. Soils were then infested with P. abappressorium, P. irregulare, P. debaryanum or P. ultimum at a rate of 10 super(3) CFU/g soil. In addition, 0.5% ground rolled oats was added to infested soils. Seven days after amending the soil, pregerminated wheat seed was sown. Rhizosphere populations of DAPG-producing bacteria were assessed using the PCR-based dilution end point assay 2 weeks after sowing. Populations of DAPG-producing P. fluorescens were similar in both infested and non-infested soils. None of the Pythium spp. affected the populations of indigenous DAPG-producing P. fluorescens on the wheat roots.

Pathogen detection is a critical step for epidemiological studies of the diseases. With the recent improvement in technology and availability of whole genome sequences, PCR-based techniques are increasingly promising for bacterial pathogen detection. The bottleneck, however, lies in the preparation of inhibitor-free template DNA from plant tissue. We have developed two simple sample preparation procedures for PCR amplification of X. fastidiosa DNA from infected almond and grape petioles. 1) Sap from fresh petioles was expressed mechanically and mixed with PW broth. The sap-PW broth mix was used immediately for PCR, or stored frozen for later PCR analyses; and 2) Plant petioles were freeze-dried and stored at room temperature, or used for PCR immediately. For PCR, the dried petioles were pulverized and powder suspension was used. Appropriate dilutions of sap-PW broth mix and powder suspension further minimized the effect of possible DNA polymerase inhibition. The two PCR methods were comparable to, but more rapid and much less labor intensive, than pathogen isolation. By coupling with real-time PCR, the two sample preparation procedures demonstrated their high throughput capacity for in planta detection of X. fastidiosa.

Here we report on the utilization of full-genome microarrays to perform gene expression studies of Pseudomonas putida KT2440 in the rhizosphere of Arabidopsis thaliana Columbia. The Arabidopsis rhizosphere, which was supported on a minimal medium agar, was inoculated with KT2440 and then sampled at 48 hr and 120 hr post-inoculation. RNA was extracted from bacteria growing in the rhizosphere as well as from bacteria growing in the absence of plant roots and used to hybridized to P. putida KT2440 microarrays. At 48 hr post-inoculation we identified 26 bacterial genes that were induced and 149 genes that were repressed in the rhizosphere at a level of 2-fold or greater. In addition, 195 bacterial genes were modulated as a function of growth in the rhizosphere 120 hr post-inoculation. Thirty-one percent of the genes up-regulated after 48 hr returned to basel expression levels 72 hr later while 85 unique genes were up-regulated only at the 120 hr sample time. The identity of these rhizosphere-modulated bacterial genes and their potential involvement in root colonization will be discussed.

Isolates of Puccinia graminis f. sp. tritici with virulence to Sr31, a gene used as the main component for stem rust resistance in many currently grown wheat cultivars worldwide, were detected in Uganda in 1999. In 2003 and 2004, many CIMMYT wheat lines planted in Kenya were susceptible to stem rust. A study was conducted to characterize the virulence of stem rust isolates from Kenya that overcame the resistance in CIMMYT wheat. Six isolates collected during 2004 at different locations were tested on the 16 stem rust race differential lines and an extended set of designated Sr genes at the seedling stage. All isolates from Kenya were virulent on Sr31, and were identified as TTKS. Stem rust resistance genes that are effective against TTKS at the seedling stage include Sr13, 22, 24, 25, 26, 27, 29, 32, 33, 35, 36, 37, 39, 40, 44 and Tmp, most of which are of alien origin. Single-gene lines carrying Sr25, 26, 29 and 44, did not confer adequate level of resistance in the adult plant stage. The virulence spectrum of the Kenyan isolates was identical to that of an isolate collected from Uganda in 1999 with virulence on Sr31, indicating that this race is now widespread in the Eastern Africa highlands.

A rust disease caused by Puccinia acroptili occurs on RK in North America but does not control it. Recently, a rust fungus was collected in Turkey from severely damaged RK; greenhouse tests confirm its potential as a candidate for biological control. Teliospores are two-celled, and urediniospores are one-celled with 3 more-or-less equatorial germ pores. For these reasons and because the host is A. repens, we have identified the fungus tentatively as P. acroptili. Severe disease developed both on stems and leaves, particularly after teliospore inoculations. Notable with teliospore inoculations was simultaneous development of both orange-colored pycnia and uredinoid pustules. Crosses between pycnia resulted in development of uredinoid aecia in approximately 50% of the cases. Ribosomal DNA sequences indicate pycnia were derived from teliospore inoculations, thus suggesting that this rust fungus is macrocyclic and autoecious. This also may be the first verification of pycnia and aecia from P. acroptili, which according to Savile, are unknown. Future research will involve comparisons with North American isolates of P. acroptili, including pathogenicity tests and molecular analyses.

The isolates collected consisted of a range of fungi, including several known and new species of Trichoderma. The endophytic habit of these Trichoderma isolates within the tissues of cocoa (Theobroma cacao) both above and below ground was confirmed. Cacao seedlings were inoculated using agar plugs by a variety of methods including inoculation on water agar plates, inoculation of seedlings at the soil line or between the cotyledons, or by planting cacao seed in precolonized soil. The isolates were shown to differ in their abilities to colonize, depending on the cocoa tissue being studied (root, stems, cotyledons, leaves, xylem, plumules, or bark) and the method of inoculation. Changes in gene expression in response to colonization were identified in cocoa seedlings using differential display techniques. From 166 differential display bands that were cloned and sequenced, 115 unique ESTs were identified. Putative functions for 58 of the 115 unique ESTs were determined based on sequence homology. A 142 member macro-array was developed consisting of the 115 endophyte associated ESTs plus 27 previously studied ESTs associated with plant defense in cacao. After macro-array analysis, the expression of differentially expressed cacao and fungal ESTs was further studied using real-time PCR techniques. Endophyte associated gene expression will be used to monitor the impact and persistence of Trichoderma species when applied to cacao in the field.

Radial growth of CS-20 was recorded on agar amended with various concentrations of the fungicides. Fungicides did not kill CS-20 at the concentrations tested. Azoxystrobin (Quadris) and chlorothalonil (Bravo) were most toxic, significantly reducing growth rate and colony size at greater than 10 ppm a.i. compared to the control. Thiram (Thiram) significantly reduced colony size at greater than 30 ppm. Mefenoxam + chlorothalonil (Ridomil Gold Bravo) significantly reduced colony size at 50 ppm or greater; mancozeb (Manzate) and mancozeb + copper (Mankocide) at 100 ppm; and mefenoxam (Ridomil Gold) and mefenoxam + copper (Ridomil Gold Copper) did not affect growth of CS-20. In greenhouse tests, tomatoes were drenched with CS-20 at seeding and just before transplanting into pathogen-infested field soil. Plants were treated with fungicides at the highest label rate. Mancozeb was applied as a seed treatment and a spray in separate treatments. Wilt incidence of plants from seeds treated with thiram + CS-20 was not different from those in the pathogen only control, indicating that thiram was toxic to CS-20. Fungicides toxic in vitro were less toxic in greenhouse tests, probably because they are applied as sprays to the aboveground portions of the plant.

It is not known whether all cultivars in this genus are equally susceptible. The objective of our research was to evaluate 23 cultivars in 9 species of field-grown Viburnum including V. burkwoodii, V. dentatum, V. lantana, V. opulus, V. plicatum, V. lentago, V. nudum, V. sargentii, and V. trilobium for resistance in detached leaf tests. Detached leaves were wound-inoculated with 6 mm agar plugs of 1-week old colonies of P. ramorum using strains 4123 and 03-74-D12A grown on dilute V-8 agar. While two mycelial agar plugs were used to inoculate one side of a leaf, a control plug of the same medium was inoculated on the other side of the leaf. Leaves were incubated in moist chambers at 20 degree C for 8 days before measurements were taken. Lesion area was determined as the percentage of infected leaf area of the total leaf area using the Assess program. We obtained significant differences for levels of resistance based on percentages of leaf areas affected (P < 0.001) and no significant differences for isolates and interactions between isolates and cultivars. Our data indicate that there is a considerable range of resistance phenotypes in this genus ranging from high susceptibility to resistance.

Since its first discovery in the United States in 2000, the soybean aphid has been shown to transmit Soybean mosaic virus but not field isolates of SbDV found in Illinois. We compared the transmission of several eastern U.S. isolates of SbDV by Acyrthosiphon pisum, (pea aphid), Myzus persicae, (green peach aphid), and A. glycines. At this time, we have confirmed the transmission of two indigenous SbDV isolates by A. glycines through symptomatology (mild rugosity and leaf curling in soybean and leaf reddening in subterranean clover), positive ELISAs with antisera to SbDV, positive PCR products using primers developed from published SbDV sequences, and subsequent transmission from these plants by A. pisum and M. persicae. This is the first report of the soybean aphid transmitting U.S. isolates of SbDV.

Barley stripe rust, caused by P. striiformis f. sp. hordei (PSH), occurred in four states and caused a yield loss of 63,000 bushels. From 313 stripe rust samples, 28 PST races and 15 PSH races were identified by testing the isolates on 20 wheat differential genotypes and 12 barley differential genotypes, respectively. Six PST races and three PSH races were new. More than 90% of the PST isolates belonged to the group of races (e.g. PST-78, PST-98, and PST-100) with virulences to Yr8, Yr9, and other resistance genes, which caused widespread stripe rust epidemics in the U.S. from 2000 to 2004. Five of the six new races belonged to this group. Some of the new races had additional virulence to Moro (Yr10 and YrMor) or Paha (YrPa1, YrPa2, and YrPa3), rendering the resistance genes no longer effective against the race group. Race PST-100 (virulent on Lemhi, Heines VII, Produra, Yamhill, Stephens, Lee, Fielder, Express, Yr8-AVS, Yr9-AVS, Clement, and Compair) was the most predominant, accounting for 50% of the PST isolates. Race PSH-71 (virulent to Topper, Emir, Hiproly, Varunda, Abed Binder 12, Trumpf, Mazurk, Bigo, and Bancroft) was the most predominant, accounting for 33% of the PSH isolates.

Little is known about its susceptibility to various pathogens but since it is closely related to petunia, speculation would implicate a number of potential diseases. In this study, we evaluate susceptibility of Calibrachoa cuttings to infection by pathogens commonly associated with greenhouse production. Rooted cuttings of cv. Colorburst Violet were transplanted into 10 cm pots containing a peat-perlite mix. Two Phytophthora and two Pythium species were cultured on LB agar. Fungal propagules from each species were suspended in distilled water. The suspension was injected into the soil 2.5 cm from the stem/soil interface of each plant. After four weeks, plants were removed from the growing medium to examine the roots. All isolates tested were pathogenic with varying degrees of symptom expression which included interveinal chlorosis of young leaves. Non-inoculated plants had healthy root systems with an abundance of primary, secondary and tertiary roots. Challenged plants showed necrotic root tips with fewer secondary and tertiary roots. We observed a 12-90% reduction in root fresh weight in challenged plants compared to non-challenged plants. All isolates from infected plants were recovered and identities confirmed.

We evaluated several chemical agents that target Oomycete pathogens for their capacity to inhibit infection of rhododendron or lilac leaves by P. ramorum (both A1 and A2 mating types). We used mycelium plugs to inoculate wounded leaves from plants previously treated with various chemicals that were (a) removed and inoculated, or (b) inoculated on intact plants, maintained in high humidity. Inoculation of leaves on chemically-treated intact plants with P. ramorum yielded results similar to those from inoculation of leaves detached from treated plants. Most of the chemicals tested reduced P. ramorum infection to varying degrees, but Subdue MAXX and an unregistered compound SA 110201 (Sipcam Agro USA, Inc.) were the most effective, even 6 weeks after application. All chemicals were fungistatic, not fungicidal. Dipping detached leaves in chemicals 24 hr prior to inoculation resulted in the same activity profile as applying chemicals to intact plants or detached leaves. These results indicate that inoculating leaves detached from chemically treated plants is an effective means of evaluating fungicides.

Fifty-seven selections were evaluated. Tests were done to determine the accuracy of the laboratory leaf disk inoculation method, which used leaves from up to one year-old vines produced in the greenhouse, to predict and correlate with the vineyard resistance of young (2 to 4 years in age) or mature (10 years or more in age) grapevines. The leaf disk method employed a spore settling vacuum tower to uniformly inoculate leaf disks in the laboratory, while vineyard evaluation employed natural inoculum from susceptible vines in the vineyard. Pearson's correlation coefficient between incidence and severity of the laboratory leaf disk inoculation method and the vineyard evaluation of mature vines was 0.999, indicating a strong correlation. The leaf disk assay quickly and efficiently identified selections that are promising for breeding mildew resistant grapevines, and confidently eliminated susceptible ones. Mildew incidence among young vines in the vineyard was very low and did not correlate with that of leaf disks. Selection of mildew resistance based on the susceptibility of young vines in the vineyard environment could result in the erroneous selection of vines that are actually mildew susceptible.

Seed and leaf tissue from field-grown plants of bmr and wild-type lines were screened for infection by Alternaria species and Fusarium species. Numbers of Alternaria species isolated from bmr lines were not significantly greater than those isolated from wild-type lines, suggesting that the bmr lines do not have increased susceptibility to colonization by Alternaria species. When fungal outgrowths from seed were selected on a Fusarium selection medium, significantly fewer seeds from bmr lines were infected with Fusarium moniliforme and other Fusarium species, suggesting that lines reduced in lignin might have increased resistance to colonization by F. moniliforme. Further support was provided by greenhouse bioassays in which peduncles of developing heads were wound-inoculated with a F. moniliforme isolate pathogenic to sorghum. Mean lesion lengths on bmr plants were significantly less than those resulting from inoculations on wild-type plants. A possible mechanism for increased resistance in reduced lignin lines is discussed.

Control of crown rust using major resistance (r) genes has not been long-lasting. Partial resistance, where the pathogen infects the host but has decreased growth, may provide greater durability. Quantifying partial resistance to rust pathogens requires either detailed measurements of disease resistance components on individual plants or polycyclic tests on plant populations. As an alternative to these tedious and time-consuming methods, a real-time PCR assay was developed to accurately measure pathogen development within the host. Taq Man registered primers and probe designed to detect P. coronata f. sp. avenae were evaluated. The primers and probe were specific and, by using a set of known standards, we reproducibly estimated fungal dry weight within the host. Image analyses of genotypes with varying levels of crown rust resistance were compared to real-time PCR assays. Real-time PCR was more consistent and sensitive for identifying differences among genotypes. Tests are in progress to ascertain if differences can be detected before disease signs appear. The real-time PCR assay is an accurate and efficient tool to quantitatively measure disease resistance and will be useful for identifying partial resistance to crown rust.

However, such mixtures are unknown in the eastern U.S. soft red winter wheat region, where powdery mildew and leaf rust regularly take a significant toll, along with other diseases and abiotic stresses. In 2003, a mixture experiment was conducted at Kinston, Plymouth, and Salisbury, NC, with four early-maturing and four medium-late-maturing wheat varieties that are grown commercially in that state. The varieties were planted in pure stands and in four 1:1 mixtures of a resistant and a susceptible variety in each maturity class. All treatments were planted in plots of both 20.4 m super(2) and 1.1 m super(2), and replicated three times for each plot size. Plots of barley, a non-host to the wheat mildew pathogen, were interspersed in a checkerboard design, and spreader rows of a mildew-susceptible wheat cultivar were planted. A moderately severe powdery mildew epidemic occurred at Kinston, where disease was assessed four times at seven- or eight-day intervals, and leaf rust severity was also evaluated at that site. Yields and test weights were determined at all locations. The quality characteristics measured were protein content, hardness, seed diameter, and falling number (a parameter related to sprouting tolerance).

Because the pathogen infects nursery stock, quarantine measures are currently used to prevent the spread of Pr based on detection using immunological assays such as ELISA, molecular diagnosis using PCR, and isolation onto Phytophothora-selective media. To compare the performance of these assays, a block of 300 camellia plants was chosen at a California nursery known to be infested with Pr. Disease symptoms, such as foliar lesions and leaf drop were recorded for each plant (as was the presence of moss) prior to foliar and potting medium sampling. Four-seven leaves and 500 ml medium were collected from each plant. Healthy camellia leaves were used as bait to isolate Pr from the potting medium of each plant. Leaf discs removed with a sterile paper punch were ground in 1 ml of TE buffer (pH 8.0). Three separate aliquots were taken from the same leaf tissue or leaf bait extracts and were either plated on PARP-V8, tested using ELISA, or subjected to nested and real-time PCR analysis. Diagnostic sensitivity and specificity of the assays were determined to compare the performance of each method for diagnosis of Phytophthora spp. or Phytophthora ramorum in camellia tissues and associated potting medium.

The disease outbreak is limited to a four county area in southern Pennsylvania. Using sequencing and phylogenetic analyses, we have determined that the Pennsylvania isolates divide into two clades, suggesting the possibility of multiple introductions. The two clades have somewhat distinct biological properties, further supporting the phylogenetic divisions. To provide context for the overall Pennsylvania population diversity, several isolates from a single orchard were sequenced. In contrast to the populations taken from around the quarantine zone, the isolates from single orchards were remarkably identical. PPV diversity levels also were determined for replicating populations within individual hosts. Like most RNA viruses, PPV generates high levels of genetic diversity within its replicating populations, with mutation frequencies ranging from 0.8 to 1.3 mutations/1000 bases. However, very little of this diversity is observed in the consensus sequences of isolates found within close proximity in a single orchard, suggesting that most of the population diversity observed at the level of replicating populations has little effect in the natural evolutionary processes of PPV.

Reports indicated that pathogens of several plant species, especially the rust fungi, were sensitive to Ni salts. Daylily rust, introduced into the U.S. in 2000 and spread widely from infected nursery stock, was selected as a model system to determine the role of Ni in disease suppression. Potted plants were sprayed with Ni at 50,100, 200 or 400 ppm till runoff, then after 10 days, inoculated with the rust fungus. Ni reduced pustule formation by 90% at 200 ppm. Spores, applied to potato dextrose agar supplemented with the Ni rates used to treat the daylily plants germinated normally. Germination was reduced slightly only at 400 ppm and phytotoxicity of plants was evident. In a second study, daylilies in outdoor beds were naturally infected with rust and treated with a commercial Ni nutrient supplement at 250 and 500 ppm or propiconazole. Plants were sprayed 3 times at 10-14 day intervals. After 30 days, untreated plants had rust pustules scattered throughout the canopy averaging 15% infection on new foliage while new foliage of plants treated with Ni or propiconazole where nearly free of rust pustules. Phytotoxicity was not observed in any of the treatments.

In experiments of single floret inoculation, infection on Abura was mostly restricted to the inoculated spikelet. To investigate the inheritance of FHB resistance, we evaluated several generations from a cross between Abura and Wheaton (a susceptible spring wheat cultivar), including F sub(1), BC sub(1)F sub(2), F sub(2), F sub(4:5), and F sub(5:6). The FHB severity in F sub(1) and reciprocal F sub(1) plants was 100%, indicating the recessiveness of the resistance. Among the 68 BC sub(1)F sub(2) families tested, 40% were homozygous susceptible and 60% were segregating. The frequencies of resistant plants in the segregating families were low, ranging from 5 to 20%. The distribution of F sub(2) (120 plants), F sub(4:5), and F sub(5:6) (97 lines) were skewed toward susceptibility, with nearly 70% of F sub(4:5) and F sub(5:6) lines having average FHB severity between 60 and 100%. Ten lines were homozygous resistant in both F sub(4:5) and F sub(5:6), fitting a three-gene model.

We examined the effect of residue burning (unburned control, light and severe burns) and wheat resistance to FHB (susceptible - Wheaton, Norm; moderately susceptible - P2375, Ingot; moderately resistant - BacUp, and Alsen) in plots established at Rosemount, MN in May 2003. All plots were left in situ (unharvested) over the winter, chisel plowed and planted to Wheaton in April 2004. Fusarium graminearum was isolated from wheat residues and surface soil at planting, air within the canopy at anthesis and early dough, and from wheat plants at hard dough. The severe burn treatment significantly reduced; the survival of FG in straw, the population of the pathogen in soil and in the air, and the colonization of Wheaton, in comparison with lighter burn or control. Plots previously planted to FHB susceptible wheats (Wheaton and Norm) had higher populations of FG in soil and air samples, and the subsequent crop was more heavily colonized than plots following Ingot, BacUp, P2375, and Alsen. Our data confirms that grain producers would benefit from destroying wheat residues and by cropping FHB resistant cultivars.

Selected trees were either in prescribed burned or in unburned check plots. Woody roots greater than 8 cm diameter were inoculated during June and August 2004. Spore dosages of 0, 50, 500, and 5,000 spores in 100 mu l of sterile, distilled water were dispensed into 2.0 cm deep x 4.0 mm diameter increment hammer holes. After 10 weeks, inoculated roots were excavated, lesions measured, and plated onto cycloheximide amended malt extract agar. Stem cambial sucrose synthase (SCSS) activity was also measured. Lesion area (cm super(2)) from June inoculations for spore numbers 0, 50, 500, and 5,000 were 2.4, 9.0, 13.7, 14.0 (burn); 2.0, 23.7, 18.0, 34.8 (no burn). August inoculations: 2.3, 4.4, 2.8, 9.1 (burn); 2.1, 2.7, 2.8, 4.5 (no burn). SCSS peaked during July and August, and declined by about 75% in September and October. The relatively small amount of spores required to initiate infection and the seasonal trend in lesion size coincide with spore load data from suspected insect vectors. These data have implications concerning research on and management of black stain root disease.

Two selection markers and two expression promoters were compared. Hygromycin B resistance was found to be superior to geneticin resistance in transforming A. rabiei, and the Aspergillus nidulans trpC promoter was more efficient than the Cauliflower mosaic virus 35S promoter CaMV35S. Extended co-cultivation times were optimal and acetocyringone concentrations >100 microM were required to generate transformants, whereas increasing the ratio of bacterial cells to conidia did not affect transformation efficiency. Hygromycin-resistant transformants carried the T-DNA as determined by PCR and the majority of insertions appeared to be random and in single copy per genome as detected by Southern hybridization. All transformants tested remained mitotically stable, maintaining their resistance to hygromycin even without continuous selection. During screening transformants for pathogenicity, two transformants were unable to infect chickpea. This technique will provide a useful tool for studying pathogenicity factors of A. rabiei.

We evaluated the impact of this rust on saplings and coppices of melaleuca trees. Puccinia psidii defoliated, deformed, and killed branch-tips of saplings and sprouts from coppices of melaleuca trees. As a result, rust infected plants were significantly shorter and bushier than the healthy ones. Additionally, P. psidii affected nutrient status in melaleuca tissues. Total nonstructural carbohydrate (TNC) concentrations in leaf-tissues decreased (P = 0.0347) with increased rust-pustule coverage on leaf-surfaces. Soluble sugar content followed the patterns similar (P = 0.0270) to those of TNC, but the starch content was generally greater (P = 0.0271) in rust-infected than in healthy leaf-tissues. Carbon to nitrogen ratio in tissues increased with increased rust-pustule coverage on leaves. We conclude that P. psidii has significant impact on growth and survival of melaleuca trees in Florida.

Fitness and aggressiveness of mefenoxam-resistant and -sensitive isolates of P. erythroseptica collected in 2001 to 2002 were determined. Zoospore production/mm of colony circumference was significantly greater for sensitive than resistant isolates, 14,191 and 9,959, respectively (P = 0.0109). Percentage of germinated zoospores at 20 degree C was not significantly different for resistant and sensitive isolates (P = 0.9598). Incidence of pink rot tuber infection was significantly greater (P = 0.0162) for sensitive than for resistant isolates at temperatures of 10, 15, 20 and 25 degree C. Optimal temperature(s) for infection was 20 degree C for sensitive isolates and 15 and 20 degree C were co-optimal for resistant isolates. Rate of growth through tuber tissue was significantly different for resistant and sensitive isolates at 3.3 degree C but not at 7.2, 10, 15,20, and 25 degree C, although growth of resistant isolates was numerically greater at all temperatures. Sexual fitness and aggressiveness of mefenoxam-resistant isolates may be greater than sensitive isolates, but sensitive isolates may be more asexually fit based on this and previously reported research.

Seed meal amendment significantly improved apple growth in all soils, but differences in pathogen suppression were observed. Brassica napus and Sinapis alba were superior to B. juncea in reducing infection by Rhizoctonia solani AG-5 and enhancing root biomass. This response was not associated with seed meal glucosinolate content. Only B. juncea seed meal did not stimulate resident Pythium spp. populations and subsequent root infection. All seed meals suppressed root infestation by Pratylenchus spp., however the impact on total soil nematode populations was dependent upon seed meal type and physical properties. Seed meal amendments induced comparable initial increases in total bacteria and fluorescent Pseudomonas spp. numbers. Although uniform for B. napus, the stimulatory effect of B. juncea and S. alba seed meal on Streptomyces populations was soil-dependent, and characteristically was delayed or less robust. This is significant as suppression of Rhizoctonia root rot by these residues is associated with amplification of NO-producing Streptomyces in the apple rhizosphere.

Reverse transcription-polymerase chain reaction products were amplified from total RNA using commercially-available and other degenerate carmovirus group primers. Sequence analysis of these products indicated that this virus was distinct from, but most closely related to, Pelargonium flower break virus (PFBV) and Carnation mottle virus (CarMV), with amino acid identities of 70-76%. However, PFBV and CarMV antisera did not react with symptomatic angelonia tissue by enzyme-linked immunosorbent assay. An agent was mechanically transmitted to Nicotiana benthamiana and virions were isolated from systemically infected leaves, and also directly from angelonia leaves, using a typical carmovirus protocol. Isometric particles similar to 28 nm in diameter were observed in virion preparations from both hosts, and in thin sections of angelonia floral tissue by electron microscopy. Analysis of dissociated virions by SDS-polyacrylamide gel electrophoresis revealed a major protein component of 33 kDa.

We have recently identified a new host selective toxin (SnTox2) from culture filtrates of Stagonospora nodorum. The toxin shows selective action on several different wheat genotypes indicating that it is a host-selective toxin (HST), The Brazilian hard red spring wheat breeding line BR34 and the North Dakota wheat cultivar 'Grandin' were found to be insensitive and sensitive respectively, to SnTox2. A mapping population consisting of 118 recombinant inbred lines of the cross of BR34 and Grandin was evaluated for toxin reaction and used to map the gene conditioning sensitivity to SnTox2. This gene, designated as Snn2, was mapped to the end of the short arm of chromosome 2D. This is the first report identifying this putative HST from S. nodorum and the chromosomal location of a host gene conferring its sensitivity. A fungal inoculation was used to evaluate the significance of Snn2 in disease. Inoculation data revealed that when using a an SnTox2 producing isolate, Snn2 accounts for as much as 60% of the disease reaction with other minor QTL accounting for smaller portions of the disease variability.

The effect of temperature, relative humidity (RH) and wetness duration on late blight incited by isolates from various genotypes and hosts were assessed on potato plants in growth chambers. Combinations of different genotypes were also evaluated for late blight development. Variation in late blight severity was observed, and highest disease was detected on the 100/111/122 genotype. Mean infection frequency on potato leaves ranged from 2 to 67%. The optimum temperature for late blight progression was 22 degree C and was similar among all genotypes. Disease levels increased with RH greater than or equal to 90%. Source of inoculum had limited impact on late blight disease development. Different genotypes of P. infestans were similarly affected by temperature, relative humidity and wetness duration. These results suggest that pathogen genotype, temperature and relative humidity can significantly affect disease development and epidemiological components.

Anecdotal evidence dating back to the 19th century indicates that G. zeae ascospores (sexual spores) are a more important inoculum source than are macroconidia (asexual spores), although the fungus can produce both types of spores during wheat head blight epidemics. To study the role of ascospores in the biology of G. zeae, we previously generated fungal strains that are genetically identical and differ only in the presence of the mating type (MAT1) locus, which controls sexual development and ascospore production. In this study, we use these mutants to demonstrate that ascospores, but not macroconidia, play a critical role in epidemics in agricultural fields, at least in Illinois. Thus, the G. zeae sexual cycle is a new potential target for control of wheat head blight.

Although this disease has been one of the most intensely studied of forest diseases, little is known about its roles in Wyoming forests. We are conducting a field survey designed to examine the geographic distribution of Armillaria species, and to characterize relationships among forest types, host species and conditions, site, and Armillaria species. Plot locations across the state were randomly selected previous to field visits using a geographic information system, forest cover maps, and road maps. About half of these sites were visited in 2003 and 2004. By the end of 2004, we sampled 132 plots in 15 forest cover types, and expect to finish 280 plots by the end of 2006. To date, Armillaria has been found at 31 locations and in 11 forest cover types. Forty-four isolates were collected and are being identified to species. Many consider Armillaria a major driver of forest structure and composition. Monitoring this disease should provide information valuable for managers interested in disease prevention and control, and forest sustainability.

AN - 19834723; 6610623 AB - An isolate of Colletotrichum gloeosporioides (Cg), which kills Russian thistle (RT, Salsola tragus), is being evaluated for use in biological control. Host range tests indicate minor infection of closely related Salsola spp., and there was limited symptom development on senescent spinach. No symptoms developed on young (non-flowering) spinach, while inoculations with C. dematium, a U.S. spinach pathogen, under the same conditions clearly damaged the plants. This suggests a possible hemibiotrophic disease response in spinach (i.e., symptom development after an extended latent period), something not uncommon among species of Colletotrichum. In research with other Colletotrichum species, latent or "symptomless" infections have been reported after induction of artificial senescence following treatment of plants with paraquat. Similar "symptomless" responses have been noted for at least three crop species in the current host range determination of Cg from RT. Truly latent infections are considered "no risk" regarding evaluation of this candidate, but the hemibiotrophic response complicates the host range determination and it raises issues concerning risk.

This study reports changes in soil fungal communities following multiple years under alternative practices, and the resumption of tomato production using length heterogeneity PCR and nonparametric multivariate analysis. After three years, soil fungal communities subjected to continuous tomato production or continuous disk-fallow cultivation were closely related. Communities in soil left undisturbed in a weed fallow system were similar to communities in a perennial pasture grass rotation. Communities in an organically managed system were unique. Following production of tomato in the fourth year, communities in the organic and pasture grass systems remained unique; whereas communities in the weed fallow became similar to communities under continuous tomato production or continuous cultivation. Fungal communities were dominated by a 341bp rDNA amplicon fragment. Cloning and sequencing indicated the dominant fragment was most related to Fusarium spp., which was further confirmed by the length of ITS 1 from single spore isolates of F. oxysporum f. sp. lycopersici. The relative abundance of the 341bp fragment was greatly decreased in organic and pasture grass systems that also had a lower incidence of Fusarium wilt.

However, biological treatments are much less effective in the control of post-emergence damping-off, since they do not colonize the plant hypocotyl and induce phytoalexin synthesis in that region of the plant. The post-emergence phase of cotton seedling disease can be controlled with systemic fungicides. However, these fungicides are not effective in controlling the pre-emergence phase of damping-off. In soil containing both pre and post-emergence pathogens neither the fungicides nor the biocontrol agents alone will control seedling disease. In an effort to control both phases of cotton seedling disease simultaneously, a series of chemical/biological combinations were used as seed treatments to determine which combinations would produce optimum disease control in soil infested with both pre and post-emergence pathogens. Tests showed that disease control was dependent on the fungicide, the quality of the seed, and the biocontrol strain used. The optimum combination appeared to be chloroneb + the T. koningii x T. virens hybrid TKG-12, although other fungicide strain combinations were nearly as effective.

In addition, Fusarium species can cause sugar beet root rot or seedling damping-off. Some strains of FOB also infect spinach and some weed species, so FOB may have a less restricted host range than is usually reported for forma specialis. We investigated the variability in strains of F. oxysporum and other Fusarium species isolated from sugar beets from different states in terms of their pathogenicity and virulence on sugar beet in greenhouse tests and their genetic variability. From a total of 173 isolates, 35 were pathogenic on sugar beets. FOB was the primary pathogen associated with yellows, with other species less common. Three species, F. oxysporum, F. solani, and F. culmorum were associated with root rot of sugar beet. F. graminearum also was isolated from beets with external yellows symptoms that had rotting around the veins in the roots. Additional isolates are being identified and tested for pathogenicity.

Botryosphaeria stem canker disease causes significant damage to pondberry including stem mortality, reduced vigor, and attenuated seed production. The black twig borer, Xylosandrus compactus, is a small, nonnative (exotic) wood-boring ambrosia beetle that chews into pondberry stems in the fall. The adults prefer to bore primarily but not exclusively into canker tissue formed in response to the stem canker fungus, tentatively identified as Botryosphaeria ribis, presumably because canker tissue is softer than healthy tissue. The borer exacerbates damage caused by the disease in several ways. It bores perpendicularly into the stem and hollows out the pith adjacent to the entry point to form a conspicuous, elongated T-shaped gallery. These galleries increase the susceptibility of the stem to mechanical breakage by wind and other physical forces. Stems are partially girdled around the entry point, contributing to dieback. Adults hibernate and overwinter in stems, emerge from canker tissue in the spring carrying fungal inoculum, then attack nearby pondberry plants or alternate hosts, producing brood chambers in stems. The behavior of this borer makes it a good candidate as a possible vector of the Botryosphaeria stem canker fungus.

Ten week old containerized shortleaf pines (full and half sib families) were inoculated with basidiospores of Cronartium quercuum f. sp. fusiforme. The resulting galls were 3 to 25 mm long at the point of inoculation after 45 days. Galls were sectioned and tissues were examined using light microscopy at four intervals; 14, 21, 45 and 90 days. Cortical and cambial tissues in the developing lesion died 21-45 days after inoculation. Host and fungal cell nuclei stained normally at 14 days. Starch grains were evident in cortical and developing ray cells. Ergastic materials such as phenols and tannins accumulated from 14 to 21 days. Resin ducts became necrotic and formed areas of dead host cells after 14 to 30 days. Cell enlargement disrupted cortical and cambial tissues but xylem elements remained normal. Gall tissues seldom formed a periderm. Rust hyphae in these dying tissues were hydrolyzed. Haustoria were few and died within 21 to 30 days. Mortality of host cells and fungal hyphae was affected by source of inoculum and pine family. Rapid cellular degradation of shortleaf pine tissues as observed in this study is one way the host can limit the fusiform rust fungus.

The most ubiquitous and common mite, Tyrophagus putrescentiae, is responsible for most mite damage to fungal cultures in laboratories worldwide. Such mites typically transmit and spread bacteria, yeast, and fungal contaminants across the surface of cultures that preclude acquisition of sterile transfers for various applications. Dicofolfumigation treatments, applied at concentrations ranging from 15 to 150 ppt in a xylene carrier, were tested with xylene and untreated controls compared to dichlorvos, using fungal cultures infested with T. putrescentiae placed in friction-sealed stainless steel canisters within plastic Petri plates. Dicofol treatments caused 100% mite mortality at all concentrations, whereas significantly less control was achieved with dichlorvos. Xylene alone also caused high mortality, but allowed some mites to escape. Mite behavior and activity was affected by all pesticide treatments. This new dicofol-fumigation method proved to be safe and effective, providing complete control of all mites (including unhatched eggs) in fungal cultures within 24 hours without affecting culture viability or exposing the operator to the fumigant.

Immediately after spraying and weekly thereafter, leaf disks taken from the edges of lesions were plated on selective media. The organism could be recovered from control, fosetyl-Al and propanocarb-treated lesions at high frequencies (64-100 percent) immediately after treatment, and recovery of the pathogen declined thereafter. The pathogen could not be recovered from mefonoxam-treated lesions until 3-5 weeks after treatment, when low frequencies (3-13 percent) were found. In no case were symptoms suppressed; lesions were easily visible in all treatments. At the end of each experiment (3-8 weeks after spraying), remaining leaves on the plant, fallen leaves and samples of stem, bud, and root tissue were plated; the organism could sometimes be isolated from buds, fallen leaves and roots but the tissue with the highest recovery was stem tissue.

Reducing teliospore germination during the infection window may lower the incidence of Karnal bunt. In laboratory assays, sodium phosphate inhibited spore germination and basidiospore production. Water agar plates were amended with monobasic or dibasic sodium phosphate (10mM) at pH 4.8, 6, 7, and 8.4. Teliospores on agar without sodium phosphate germinated at comparable rates (47, 48, 44, and 43%) at each pH. Germination was reduced at all pH levels by both monobasic and dibasic sodium phosphate. The greatest effect was at pH 7, amounting to reductions of 73 and 93%, respectively, for monobasic and dibasic sodium phosphate. In a separate study, germination rates were comparable among unamended plates (50%) and plates amended with either sodium chloride (46%) or potassium chloride (47%) at 20 mM. This suggests that the phosphate anion and not the cation, is responsible for inhibition. The effect of sodium phosphate on spore germination on the soil surface is currently under investigation. Timely applications of a phosphate compound to infested field soils may inhibit or delay teliospore germination during the wheat infection window and thereby reduce disease incidence.

Phytophthora ramorum produces abundant chlamydospores but their purpose in the disease cycle of Sudden Oak Death is unknown. Chlamydospores of A1 and A2 isolates of P. ramorum were produced to infest soils at 100 spores/cm super(3) soil in sand, potting soil mix, and natural biologically active forest soil. Direct plating was used to quantify the viable chlamydospore population. The soils were maintained in bags at 22 degree C and 4 degree C and in plastic pots under normal greenhouse conditions. After 4 months, there was no decline in the population of chlamydospores held at 4 degree C in any of the soil types. The decline was gradual for chlamydospores held at 22 degree C, but was much more rapid for soils kept in the greenhouse. Survival of chlamydospores was lowest in the forest soil under greenhouse conditions. Real Time PCR will also be used to detect P. ramorum in the soil. To examine chlamydospore pathogenicity, Rhododendron 'Cunningham's White' plants were inoculated with soils infested with 40 chlamydospores/cm super(3). After 4 weeks, the rhododendron plants had healthy root systems, but P. ramourm could be isolated from the roots indicating infection had occurred.

Roots were inoculated by pouring suspensions as 10 mL aliquots into pots and waiting at least 25 days before plating (washed or surface-sterilized for 5 min in 0.025% sodium hypochlorite). Of weeds tested, only Epilobium and Pteris showed foliar symptoms. The pathogen could also be isolated from the roots of Epilobium, whether washed or surface-sterilized, suggesting that roots were internally colonized. P. ramorum could be re-isolated in low numbers from the washed roots of various weeds, but not from surface-sterilized ones, suggesting superficial colonization of the rhizosphere.

Potential protein coding regions (ORFs) were identified that encode proteins similar to virulence-associated proteins involved in cell-to-cell adhesion and conjugal DNA transfer. Putative proteins encoded by the ORFs include SkARP1, highly similar to the ScARP1 adhesin protein involved in attachment of S. citri to insect vector gut membrane, and proteins containing domains similar to those in proteins of the Type IV secretion system in pathogenic bacteria, suggesting that the spiroplasma possesses a related secretion system. Plasmid pSKU146 also contains two identical ori T-like regions, each containing a potential nick sequence identical to that in the IncP conjugative plasmid family. Features of pSKU146 suggest that the plasmid functions, or once functioned, as a mobile genetic element in conjugative transmission of spiroplasma pathogenicity-related genes.

In part, this has been driven by an increased concern about crop biosecurity and the recent spread of economically important rust pathogens. Real-time PCR assays using TaqMan probes have been developed for cereal and grass rusts including stem rust (Puccinia graminis), stripe rust (P. striiformis), crown rust (P. coronata) and leaf rust (P. recondita and P. triticina). These assays are species specific and work with either isolated spores or infected plant material. Assays are linear over four orders of magnitude and can detect DNA levels equivalent to 10 urediniospores. A rust specific internal standard has been developed as an internal control. In addition, this technology provides new tools for properly identifying rust samples, when the characteristic spores (teliospores) and hosts information are not available.

In 2003, an epidemic of dying YST plants was found near Kolzani, Greece. Diseased YST plants were sent to the Foreign Disease Weed Science Research Unit, USDA/ARS, Ft. Detrick, MD where the causal organism of the disease was isolated. Based on culture characteristics, fungal morphology and ITS sequence the organism was identified as Cladosporium herbarum. Rosettes and bolted YST plants were inoculated with spores of the fungus and placed in a chamber with 8 hr dew and 12 hr light daily. Plants in the rosette stage were resistant, but the fungus was very aggressive on bolted plants. Within 4-6 days of inoculation necrosis developed on leaves and stems and then spread to capitula, often resulting in plant death. The fungus was also aggressive on developing flowers. The fungus was reisolated consistently from plants in two separate tests. Results of host range tests will establish if this isolate of C. herbarum has potential as a biological control agent of YST in the USA.

Grain-based inoculum was superior to sclerotia in inducing disease at all inoculation dates. The lowest rate of grain/mycelia inoculum (40 g/6 m row) produced significantly more disease (37%) than even the highest rate of sclerotia (80/row), which produced 12% stalk rot. The optimal inoculation technique consisted of digging a 4-cm deep furrow 15-cm from the plants at the V-6 stage and uniformly placing the mycelial-colonized grain in the furrow. Using the millet/mycelia inoculum, twenty hybrids were evaluated at four locations for tolerance to Sclerotinia stalk rot. Rankings were similar at all four locations, despite differences in climate and disease severity at each location. Averaged over four locations, stalk rot reaction ranged from a low of 17% to a high of 53%.

Plants were inoculated with sporangial suspensions (2000-6800 sporangia/mL) from a P. ramorum isolate originally from camellia. Inoculated plants were placed in a dew chamber at 20 C for 4-5 days, then incubated in the greenhouse for up to a week at 20 C and rated for defoliation and lesions on leaves. Camellias differed in susceptibility to the pathogen, with C. sasanqua 'Midnight Lover' and C. oleifera the most susceptible, exhibiting defoliation up to 41.4% and lesions covering up to 9.8% of area of inoculated foliage; C. japonicum and C. sinensis were intermediate, while C. brevistyla and C. crapnelliana showed no symptoms. Defoliation of camellias occurred even when leaves showed no visible lesions, although the pathogen could often be recovered from the petiole of the fallen leaf. Rhododendrons inoculated at the same time showed little defoliation but significant lesion development, up to 72% of inoculated leaf area.

The role of Macrophomina phaseolina (MP) and Fusarium sp. (FS) in the early soybean [Glycine max (L.) Merr.] production system (ESPS) was also investigated. There was a significant effect due to year, irrigation, and MG. Maturity group averaged over years, DOP, and irrigation showed that MG IV seed had a significantly higher PL incidence than did MG V seed. Irrigated treatments in dry years produced a higher level of PL than did nonirrigated treatments. There were high and significant inverse relationship between incidence of seed infected with PL and seed germination (r = -0.87, P less than or equal to 0.05), and between incidence of seed infected with FS and seed germination (r = -0.65, P less than or equal to 0.05). This research highlights not only the importance and significance of PL but also the importance of other organisms that in combination may inflict considerable damage to quality of seed harvested from ESPS plantings.

The large financial burden to growers in terms of yield losses, post-harvest losses or increased production costs due to fungal plant disease epidemics are well documented. Unfortunately, plant diseases can also result in large costs to society. These costs can come in different forms. I will discuss the social impact of fungal diseases using several historic as well as a recent example. The Irish potato famine, a result of several years of severe potato late blight epidemics in the 1840s, resulted in large demographic shifts in both Europe and the US. Dutch elm disease was responsible for the disappearance of the American elm as a shade tree in urban environments. Recently, the new pathogen Phytophthora ramorum causing sudden oak death (SOD) appeared simultaneously in Europe on Rhododendron and Viburnum and in the U.S. on tanoak and coast live oak. This pathogen has a wide host range and affects nursery crops as well as forest species, thus creating a bridge between urban and natural environments. SOD has already resulted in extended death of forest and landscape trees and federal quarantines are now in effect to curtail the spread of P. ramorum. Only time will tell what the full impact of SOD will be on society.

FB1 (15 uM and higher) significantly reduced growth and development of susceptible hybrids (e.g., 'Silver Queen'). We hypothesized FB1 phytotoxicity was ancestral in corn, with FB1-resistance being the derived phenotype. We have screened lines of corn, teosinte, and Tripsacum for resistance or sensitivity to FB1 (100 uM). Data support FB1-resistance as being derived. Based on previous data from seedlings inoculated with unique fungal strains, translocation of FB1 was postulated to occur independent of fungal infection. Corn seedlings were exposed for 10 days to 1 uM FB1 (not inhibitory). Seedlings were analyzed for accumulation in the leaves using LCMS, but FB1 was not detected. These experiments are being repeated with higher FB1 concentrations. A real-time PCR assay was developed to detect the fungus in planta and is being used to assess infection in both symptomatic and asymptomatic associations in conjunction with further FB1 analyses.

During the past few decades, phytotoxins have been employed as tools contributing to fundamental discoveries in plant pathogenesis, host specificity, mechanisms of resistance and susceptibility, secondary metabolism, fungal genome organization, plant cell and organelle functions, and fungal ecology. Their application to fundamental questions has followed the development of prevalent biological concepts. As components of molecular approaches, phytotoxins will allow investigators to make substantial progress toward defining: signaling pathways in defense responses; evolution of pathogen races; virulence and avirulence factors; the role of programmed cell death in plant disease; phenomena that distinguish resistant and susceptible phenotypes; evidence for horizontal gene transfer; disease management strategies, and countless others. Some of the hallmarks of phytotoxin research and those who contributed them will be reviewed, and future promises of phytotoxin research will be discussed.

Eradication is considered a biologically sound regulatory response when a pathogen is detected if incidence is low, distribution is limited, and scientific studies indicate a possibility of elimination. However, a pathogen can affect both homeowner and commercial agricultural interests in the same region when the same plant species is grown in residential gardens and commercially. This is often the case for fruit and nut tree crops such as citrus, peach and apple. If eradication is pursued, then both residential tree owners and commercial growers are affected. Depending upon community composition, cohesiveness and common interest, the support for eradication among residential homeowners and commercial growers can coincide or be in opposition. For example, in Florida the citrus industry finds itself in opposition with some segments of the residential community over citrus canker eradication, whereas the peach industry of Pennsylvania is more in harmony with residential owners, both of whom support plum pox virus eradication. These two eradication programs and others will be used as examples to present the range of compatible to opposing objectives of the two groups, the legal, social, and economic ramifications, and possible resolutions.

It is a very important plant to the nursery industry in the U.S., so its susceptibility to ramorum blight is of interest. Seven accessions of lilacs (Syringa x prestoniae 'Alexander's Pink', S. oblata 'Betsy Ross', S. x tribrida 'Lark Song', S. x laciniata, S. meyeri 'Palibin', S. pubescens 'Miss Kim' and S. vulgaris) were inoculated with a sporangial suspension (approx. 4000 sporangia/mL) and incubated in a dew chamber (20 degree C) for 4-5 days. Plants were rated for defoliation and disease (the number of infected leaves and percent leaf area affected). 'Alexander's pink' was not very susceptible (only 0.5% infected leaves), and 'Miss Kim' was moderately susceptible, while all other lilacs tested developed large black lesions on 20-40% of leaves and suffered some defoliation.

Based on rDNA internal transcribed spacer (ITS) sequences from single telial columns, infections were caused by two rust species that differ at 27 informative ITS sites. All five collections of P. racemosa infections were C. ribicola (CR). Of two collections of Ca. miniata, one was infected with CR and one with C. coleosporioides (CC) (stalactiform rust). One collection of Ca. rhexifola and two of P. bracteosa were infected with CC. Subsequent artificial inoculations using CR aeciospores from whitebark pine produced uredinia and telia on Ca. miniata, P. racemosa, and Ribes nigrum. CR urediniospores from Pedicularis caused infections and produced uredinia and telia on R. nigrum. The latter initiated infections on western white pine seedlings. Thus, these isolates can complete their lifecycle and are not specific to alternate host genus. Further research aims to determine the geographic extent of CR infections of Scrophulariaceous hosts, their role in white pine blister rust epidemiology, and the genetic basis for infection of these hosts.

Two bell pepper cultivars, Charleston Belle and Carolina Wonder; two cayenne cultivars, Carolina Cayenne and Charleston Hot; and three Scotch Bonnettype cultigens, PA-353, PA-398, and PA-426 were tested using three inoculum levels of P. capsici (0, 2.0 x 10 super(4) and 4.0 x 10 super(4) zoospores/plant). The bell cultivars Capistrano and Enterprise (susceptible to P. capsici) and Aristotle (resistant) were included as reference controls. Disease resistance was measured by computing the area under the disease progress curve (audpc), which was based on the disease severity ratings at 7 and 14 days after inoculation. The disease severity rating scale ranged from 0 (no disease) to 5 (dead). 'Aristotle' was not infected at either inoculum level. According to the audpc, the Scotch Bonnet-type cultigens PA-398 and PA-426 were the most resistant genotypes at the lower inoculum level while PA-353 was the most resistant at the higher inoculum level. However, the disease severity levels of PA-353, PA-398, and PA-426, were higher (P < 0.05) than the resistant control Aristotle.

Little is known about the molecular biology of this group and tools for understanding gene function have not yet been established. The wheat leaf rust pathogen Puccinia triticina is an economically significant, biotrophic, basidiomycetous fungus. A set of parameters was established for the transformation of urediniospores of P. triticina. The expression from three heterologous promoters (actin; EF-1alpha, elongation factor 1-alpha; and Hss1, heat shock 70 protein) derived from P. graminis and the potential for insertional mutagenesis were evaluated. The beta-glucuronidase (GUS) gene was used as a marker for transient expression. When transferred into P. triticina urediniospores, transient expression was observed across four helium pressures using one size of gold and three sizes of tungsten microprojectiles. Each of the three promoters displayed strong transient expression in germinated urediniospores, however higher numbers of GUS-positive urediniospores were observed when either the actin or Hss1 promoters were used. Secondly, using a linearized cloning plasmid, stable transformation and integration in the genome was achieved as demonstrated by GUS expression, PCR, and Southern analysis. Possible concamitant insertional mutagenesis of several avirulence genes was selected for in wheat cultivars harboring the cognate resistance genes.

Several studies suggest that choline and betaine, found in wheat heads and anthers, stimulate germ tube growth of Fusarium head blight (FHB) pathogen Gibberella zeae. In the present studies, yeasts and bacteria were isolated from wheat anthers. Several choline metabolizing strains (CMS) were discovered that reduced FHB in greenhouse and field trials. Prior to conducting trials of combinations of CMS and the non CMS yeast antagonist C. nodaensis OH 182.9 (NRRL Y-30216), dose response trials were conducted with 3 CMS strains to determine the relationship between dose and biocontrol efficacy. Fully colonized broths that were diluted to one-quarter strength were frequently effective in reducing FHB but further diluting broths of CMS antagonists often reduced efficacy below the P = 0.05 significance level. Combining CMS antagonists with C. nodaensis OH 182.9 resulted in a modestly enhanced disease reduction effect compared to OH 182.9 alone in repeated greenhouse trials. Combinations of OH 182.9 and CMS antagonists will be field tested on soft red winter wheat in 2005.

To estimate forage yield losses caused by these and other fungal pathogens in sod, samples of diseased- and healthy-appearing bermudagrass sod from three swine waste application sites were grown in the greenhouse with and without weekly fungicide drench treatments. Loss estimates were based upon dry-matter yield increases observed in fungicide-treated samples in comparison to untreated samples. Mancozeb usually produced the greatest yield increases of three fungicides tested. In eight experiments with diseased-appearing sod, first-harvest losses in potential forage yield estimated with mancozeb were 0-57% (mean 37%). In five experiments with healthy-appearing sod, similar loss estimates were 0-35% (mean 16%). Results indicate that fungal diseases in sod and roots may cause major yield losses in forage bermudagrass grown for nutrient conservation on swine waste application sites.

Several isolates have been reported to be plant-growth promoters, plant-health enhancers and successful in preventing the development of plant diseases. B. mojavensis RRC 101 exhibited strong antagonism to Fusarium verticillioides and other pathogenic fungi by producing zones of inhibition when bioassayed on nutrient agar. The inhibitor caused enlarging of hyphae and conidia, degradation of cellular matrix and cell walls of this and other sensitive fungi. The chemical identity of the antagonistic compound is unknown, but assumed to be a type of biosurfactant, a cyclic lipoprotein characteristic of inhibitor produced by Bacillus species. We examined cultures of B. mojavensis for similar lipoproteins. The antifungal fraction produced in 5-7 day-old liquid culture medium was subjected to precipitation at pH 2, extraction with both methanol or methylene chloride, and its physical and chemical properties determined. This substance was assayed against F. verticillioides and compared with the inhibition produced from authentic standards of iturin A and surfactin, two known fungal inhibitory biosurfactants.

When applied to wheat heads at 3 days before pathogen inoculation with Gibberella zeae, sodium salicylate (NaSA) and isonicotinic acid (INA) at 10 mM significantly reduced FHB severity compared to the nontreated control. NaSA and INA at concentrations of 1 and 5 mM had an additive effect with the yeast antagonist C. nodaensis OH 182.9 on FHB reduction but DL-beta-amino-n-butyric acid (BABA) did not. When sprayed onto the leaf sheath surrounding heads at 10 days prior to pathogen inoculation, NaSA, INA and BABA at 1 mM reduced FHB severity indicating that induced systemic resistance was, at least in part, responsible for FHB disease suppression. Induced FHB resistance was achieved by treating wheat with INA at concentrations as low as 0.1 mM. Data from this study suggest that chemical SAR inducers can induce resistance in wheat against FHB, and improved control of FHB disease can be achieved by incorporating chemical inducers of SAR with the FHB biocontrol agent OH 182.9 under greenhouse conditions.

Diverse fungal genera and species, commonly associated with wood decay such as Irpex lacteus, Serpula lacrymans, Postia placenta, Armillaria mellea, and Geophyllium tracheum were grown in potato dextrose agar (PDA) in petri dishes at 25 degree C for 10 days. PDA plates containing actively growing fungal mycelia in four replicates were exposed to 0, 80, 96, 112, 128, 144, and 168 mg/L of sulfuryl fluoride and methyl bromide for 8 hours duration. All fumigations were performed at about 22 degree C in sealed glass jars. The fumigant concentrations in the jars and sorption were also monitored. After fumigation, fungal mycelial plugs (1.5 cm diam.) were plated on PDA, incubated at 25 degree C for 10 days, and mycelial growth (cm) was measured. Complete inhibition (100%) was noted at concentration by time (CxT) value as low as 576 mgh/L of sulfuryl fluoride and methyl bromide on growth of Serpula lacrymans and Armillaria mellea. However, these fumigants were not effective against Irpex lacteus, Postia placenta, and Geophyllium tracheum at the concentrations and duration of exposure investigated. These results indicate that the fumigants such as sulfuryl fluoride and methyl bromide may be effective for control of some wood decay fungi under similar substrates and treatment conditions.

Clues from genetic diversity and relatives AN - 19769942; 6610459 AB - Ceratocystis fagacearum was identified in 1942 as the causal agent of oak wilt, a disease currently limited to the middle to eastern United States. Its origin remains obscure. Available evidence could support either the local genesis of a new and reproductively isolated strain or species, or introduction. Estimates of low genetic diversity in C. fagacearum from both nuclear and mitochondrial RFLPs suggest that the population has gone through a recent genetic bottleneck. Ceratocystis fagacearum could have originated as a strain or hybrid of native endemic species, but its rDNA sequence is distinct from all known species. The closest known relatives of C. fagacearum are C. adiposa, C. moniliformis, and three ambrosia beetle symbionts (Ambrosiella spp.), none of which are strongly pathogenic. If C. fagacearum is an introduced fungus, pathogenicity may be higher to its acquired than its original hosts, and C. fagacearum is more aggressive on members of the red oak group than on members of the white oak group. The related plane tree pathogen, C. fimbriata f. platani also has low diversity in its recently established European population compared to the native North American population, as estimated using microsatellite and other nuclear and mitochondrial markers.

In 2003, however, 40 plants in an oat field that exhibited symptoms of red leaves typical for BYD were all serologically negative for BYDV-PAV, -MAV, -SGV, and CYDV-RPV by ELISA assays. Only one plant produced a RT-PCR product using standard "universal luteovirus" primers, Lu 1 and Lu 4. Sequence data revealed that it was a PAV-like isolate. The same 40 plants were re-assayed using new primer sets (Yan-R and Shu-F, or Yan-R and MAV2-F) described by Malmstrom and Shu, resulting in RT-PCR products of predicted sizes for over half of these. DNA sequences of these were found to be most similar to BYDV-MAV isolates by a NCBI Blast search. The Alaskan MAV-like isolate coat protein gene sequences differed in several regions that otherwise are conserved among other MAV isolates. Specific differences in one or more of these regions may determine serological variation among MAV-isolates, and could account for negative ELISA assay results with the Alaskan MAV-like isolates. This is the first report of BYDV-MAV in Alaska.

Testing for all Rubus viruses with available detection tests failed to identify a known virus in the plant. DsRNA was extracted and cloned. Sequence analysis revealed the presence of three novel viruses in the plant designated as Glen Clova virus -1, -2 and -3 (GC-1, -2, -3). GC-1 is a novel closterovirus with sequence similarity to Citrus tristeza virus. GC-2 is a member of the family Flexiviridae and shares greatest similarity with the unassigned members of the family infecting rosaceous hosts. GC-3, a unique plant virus, belongs to the Dicistroviridae, a family of picorna-like insect viruses and is similar to a novel virus identified recently in strawberry (Tzanetakis and Martin, unpublished data). The detection protocols developed have verified the presence of the viruses in other Rubus plants that originated in the U.S.A. Transmission tests are currently underway.

A. majus is native to the Mediterranean but it is cultivated in major growing areas including Holland, Israel, the UK, and the U.S. and is frequently used in the floral trade to add a lacy look to bouquets. A. majus is frequently confused with roadside Queen Anne's lace, Daucus carota, which is a common weed in the U.S. Virus-like symptoms including mosaic, generalized chlorosis, vein clearing, interveinal chlorosis, leaf deformities, and leaf rugosity were observed in two cut-flower production fields in south Florida in March 2005. Cylindrical inclusions typical of a potyvirus infection and testing with a commercially-available enzyme-linked immunosorbent assay for multiple potyvirus species indicated the presence of a potyvirus. An additional inclusion body in A. majus and symptoms on mechanically inoculated Chenopodium quinoa indicated that a second virus may also be present. There are no prior reports of a virus infecting A. majus in Florida. Elsewhere, Anthriscus latent virus, Caraway latent virus, Celery mosaic virus, Parsley green mottle virus, and Parsnip leafcurl virus have been reported.

The M strain is considered the most easily aphid transmissible and epidemic form in peach. The D strain is the oldest recognized strain, most widely distributed worldwide, and the only strain found in the U.S. Very little is known about the interactions among strains when co-infecting the same tree seedlings. Utilizing the green peach aphid (Myzus persicae) as the vector, we inoculated replicated sets of Lovell peach seedlings with the M, D, and EA strains of PPV, singly, and in all combinations, simultaneously and sequentially with a three-week period between strain inoculations. Symptoms were recorded as they appeared and test plants were sampled periodically and new growth analyzed by ELISA, PCR, and subsequent aphid transmission. A multiplex PCR assay was developed to determine the presence of each strain in various tissues before and following vernalization.

A prototype unit was built and deployed for citrus canker studies in Miami. The second generation prototype, a self-contained, semi-mobile, computer-controlled unit, was constructed by USDA, APHIS, PPQ. The 3 inch double walls of the greenhouse are constructed of custom extruded aluminum framing sheathed with double layer Lexan panels. Environmental parameters (temperature, lighting, CO sub(2), and watering) are continually monitored and controlled by a computer data acquisition and feedback control system. Basic laboratory equipment includes: a refrigeration/freezer, biosafety cabinet, incubator, autoclave and a HEPA air filtration unit. An emergency generator functions automatically as a power back-up and can also provide full electrical power in the absence of local electricity. Other features include a holding tank for effluent, metal diamond plate floors, central channel drain, irrigation/fertigation system for the greenhouse plants and external field plots. This new unit will be used for citrus canker research and in-field molecular diagnostics, but more importantly, can be replicated and rapidly deployed by APHIS for additional emergency programs as outbreaks of new high consequence quarantine pests and pathogens occur in the U.S. JF - Phytopathology AU - Parker, P AU - Gottwald, T AU - Cook, A AD - USDA-APHIS-PPQ-CPHST-PDDML, Edinburg, TX, USA Y1 - 2005/06// PY - 2005 DA - Jun 2005 PB - American Phytopathological Society, 3340 Pilot Knob Road St. Paul MN 55121-2097 USA, [URL:http://www.apsnet.org/phyto/top.asp] VL - 95 IS - 6 SN - 0031-949X, 0031-949X KW - Microbiology Abstracts A: Industrial & Applied Microbiology KW - Citrus KW - Refrigeration KW - Temperature effects KW - Canker KW - Metals KW - Computers KW - Irrigation KW - Electricity KW - Pathogens KW - Effluents KW - Aphis KW - Greenhouses KW - Filtration KW - Aluminum KW - Quarantine KW - Drains KW - Feedback KW - Pests KW - Carbon dioxide KW - Data acquisition KW - A 01360:Plant Diseases UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/19769114?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Amicrobiologya&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=conference&rft.jtitle=Phytopathology&rft.atitle=Development+and+deployment+of+a+mobile+containment+greenhouse+laboratory&rft.au=Parker%2C+P%3BGottwald%2C+T%3BCook%2C+A&rft.aulast=Parker&rft.aufirst=P&rft.date=2005-06-01&rft.volume=95&rft.issue=6&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Phytopathology&rft.issn=0031949X&rft_id=info:doi/ LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2008-10-01 N1 - Last updated - 2015-03-27 N1 - SubjectsTermNotLitGenreText - Canker; Temperature effects; Refrigeration; Metals; Computers; Irrigation; Pathogens; Electricity; Effluents; Greenhouses; Filtration; Aluminum; Quarantine; Feedback; Drains; Pests; Carbon dioxide; Data acquisition; Citrus; Aphis ER - TY - JOUR T1 - The APHIS-PPQ Permitting System for movement of live plant pathogens into and within the U.S. AN - 19769033; 6610553 AB - The United States Congress granted authority for the USDA-APHIS-PPQ to regulate importation and interstate movement of plant pathogens. Federal regulations implementing the Act are at 7 Code of Federal Regulations Part 330.200. All importations and interstate movements of plant pathogens, regardless of the pathogen's distribution, require a Federal permit, including specimens of potentially infected plant material imported or moved interstate for diagnostics. Review of permit applications typically includes facility inspection. Each permit includes standard and specific conditions, permit conditions for interstate movement of native pathogens are least stringent. International movement of living plant pathogens became more complicated after 2001. More Federal agencies (e.g., Department of Homeland Security) now regulate and monitor movement of plant pathogens. Over the next few years, APHIS intends to revise the USDA permit regulations to bring them more in line with current scientific, regulatory and international thinking in plant biosecurity.

Plots consisted of two rows (9 m long with 0.91 m row spacing), and were arranged in a randomized complete block design with four replications. Because of a low disease incidence of TSWV in 2002 only one reading was taken at 135 days post planting, where Georgia Green and Georgia Hi Oleic exhibited the least disease incidence. In 2001 and 2003 infection of peanut cultivars with TSWV was observed as early as 30 days post planting, and TSWV disease developed gradually throughout the two growing seasons. In 2001, area under disease progress curve (AUDPC) for Georgia Hi Oleic, Georgia Green, and Tamrun 96 were 162, 202 and 212, respectively, whereas Okrun, Tamrun 98, and Southwest Runner had 310, 341, and 373, respectively. In 2003, AUDPC for Georgia Hi Oleic, Georgia Green, and Tamrun 96 were 120, 125 and 187, respectively, whereas Tamrun 98 and Okrun had 215 and 230, respectively. In summary, data showed that Georgia Green, Georgia Hi Oleic and Tamrun 96 exhibited the best resistance to the naturally occurring TSWV isolates in the Pearsall area.

Originally from South America, brugmansia is popular as a landscape plant in the tropics and subtropics and as a container plant in temperate regions. It is characterized by fragrant, trumpet-shaped flowers of various colors. Virus-like symptoms including a mosaic of light and dark green were observed on the leaves of several brugmansia plants in a south Florida nursery in November 2003. Inclusion body morphology and electron microscopy of leaf dips indicated the presence of a potyvirus. Supporting evidence was obtained by testing with a commercially-available enzyme-linked immunosorbent assay for multiple potyvirus species. Sequence analysis of similar to 1.7 kb 3' terminal virus genome fragments amplified by reverse transcription-polymerase chain reaction from total RNA showed 99% nucleotide identity to the corresponding region of Colombian datura virus (CDV) sequences in GenBank. This confirmed the diagnosis and represents the first report of CDV infection of brugmansia (or any other species) in Florida. CDV was detected in Brugmansia spp. elsewhere in the United States 35 years ago but was considered no longer present. A broader survey is in progress.

The seed-borne nature of PepMV coupled with easy mechanical transmission make tomato seed a potential inoculum source. The current seed health test for PepMV relies mainly on ELISA. For a seed lot with low level of viral contamination, ELISA may not be sensitive enough. RT-PCR is a good alternative. Immunocapture (IC) was used to capture virus particles with PepMV-specific antibody absorbed to PCR tubes. The seed or tissue extract was prepared with a general ELISA sample extraction buffer without RNA isolation. This immunocapture procedure enriched virus particles while eliminating potential PCR-inhibiting compounds. Utilizing Realtime, IC, RT-PCR allowed us to perform an entire assay, from sample extraction to amplicon detection, in a single reaction tube. The PepMV specific primer set and TaqMan probe were designed based on the consensus sequence generated from a multiple genome sequence alignment of the available PepMV sequences plus two additional isolates characterized recently in our laboratory. The single-tube format eliminated the potential for cross contamination during sample transfer in RT-PCR. Sensitivity of the detection could reach up to 1:10 billion dilutions (w/v) in tomato seed or tissue samples in comparison with only 1:100 in an ELISA.

The incidence of SCYLV infected sugarcane plants averaged 89% for 15 grower fields (sampling 100 plants per field comprising 8 cultivars). In the CP-variety development program, plants germinated from true seed were virus free but the incidence of SCYLV increased with exposure to natural infection. After 3 years in the CP-variety development program the incidence of SCYLV was 30.1% in the 4705 Stage II clones tested from 1998 through 2002. After three years additional exposure, the incidence of SCYLV in the 61 clones that were selected and advanced to Stage IV was 55.6%. Only 10 clones (testing 40 plants each) at this stage had an incidence of SCYLV below 25% and only one clone tested negative for the virus. Presently, no selection pressure is placed against clones having SCYLV in the program but this will probably change. Plants of meristem-tissue-culture derived seedcane were initially free of the virus. However, the incidence of virus due to natural infection increased in plants after two years exposure to natural infection of five cultivars monitored with differences ranging from 20 to 86% infection. The use of virus free seedcane may be a useful control practice especially in clones where the virus spreads slow.

Symptoms include deep bleeding vertical cankers that exude a bacterial-laden reddish brown sap. We have developed a robust PCR-based technique to detect B. rubrifaciens in soil and symptomless infected trees. B. rubrifaciens produces a unique red pigment called rubrifacine, which was exploited by generating mutants defective in pigment production. Two unique insertion sites were identified that exhibited no nucleotide homology to closely related bacterial phytopathogens. The first region is homologous to nonribosomal peptide synthetases and the second has homology to the outermembrane lipoprotein slyB from enteric bacteria. PCR primers were designed to amplify these two loci involved in pigment production. We also designed PCR primers to a unique region of the 16S rDNA from this bacterium. B. rubrifaciens was detected from DNA isolated from infected walnut sap, spiked soil samples, and infiltrated walnut leaves.

MRFV is transmitted in a persistent manner by leafhoppers of the genus Dalbulus, with D. maidis as the main vector. The host range of MRFV is restricted to the Gramineae, including maize, teosinte, and the perennial Zea spp. MRFV occurs in widely different ecological niches, from warm coastal plains to cool highlands, and at altitudes of 2000-3000 meters above sea level. It has been proposed that MRFV, its insect vector, and maize host coevolved in a triad in which the parasitic members (insect and virus) display highly specialized interactions. Phylogenetic analysis of the coat protein sequence of several isolates of MRFV collected from Central and South America separates the isolates into four geographically distinct sub-groups. Genetic distances between the isolates suggest that MRFV originated in Mexico or Guatemala from which it spread. Computer-based analyses will be presented to support this hypothesis.

The detection of Lxx by tissue-blot immunoassay (TBIA) or conventional polymerase chain reaction (PCR) is inconsistent for plants younger than 6 months old. The efficiency of these commonly used diagnostic methods depends on the titer of the bacterium in stalk sap that increases during the growing season. Due to the fact that 5-6 month-old stalks of sugarcane are used as seed cane to plant a new crop in Louisiana, a diagnostic procedure is needed for use earlier in the growing season. A real-time PCR assay was developed to increase the sensitivity of Lxx detection and to provide a method to quantify susceptibility of cultivars to Lxx infection. Sap from mature stalks of 20 cultivars of sugarcane was tested for the presence of Lxx using both real-time PCR and TBIA. Detection of Lxx by the two methods was in agreement. Real-time PCR results were also used to rank the tested cultivars for susceptibility to Lxx infection according to the relative titer of bacteria in the sap. The real-time PCR assay also correctly detected Lxx in leaf tissue of one-month-old sugarcane plants. Detection of Lxx this early in plant development with an immunoassay or conventional PCR assay has not been previously successful.

Loblolly pine stands in 3 southern states (with a predominance of sites in central and southern Alabama) are reported to be declining based on data from Forest Health Monitoring plots established in the 1990's. Current studies of affected stands show a strong correlation with (upland) site, deterioration of fine roots, presence of a fairly constant set of insect associates, and infection by Leptographium spp. affecting the primary roots. The influence of fire, previous agriculture, and landform are other factors that may have a role in the loblolly decline complex. The symptoms of the decline are sparse crowns, short chlorotic needles, and reduced radial growth primarily above 40 years of age and first apparent in trees in the 40-50 year age class. Mortality can occur beginning as little as two to three years after first symptom expression. Although the symptoms of the decline complex are similar to those of littleleaf disease, the site conditions on stands are found expressing this decline are different. On upland sites on federal lands, loblolly pine is the major forest type since it was used for watershed restoration and is easily regenerated. Many of these sites are now managed for red-cockaded woodpecker (RCW) habitat and decline of the pine stands is impacting the long-term habitat needs of this endangered species. One of mitigations recommended for decline sites is to convert them to longleaf pine where site conditions are suitable to fulfill the habitat requirements for RCW. Additional monitoring plots are being installed on National Forest upland sites in Texas, Louisiana, Arkansas, and Mississippi. This monitoring process will help define the range and impact of loblolly pine decline and will further assess Leptographium spp. component of the pine decline complex.

Isolates of Puccinia graminis f. sp. tritici with virulence to Sr31 were identified from Uganda in 1999. Similar virulence was observed in Kenya in 2003 and 2004. An isolate collected from Uganda in 1999 and an isolate collected from Kenya in 2004, identified as race TTKS, were used to evaluate U.S. and CIMMYT wheat. Cultivars and advanced breeding lines (450) in various wheat classes from U.S. and 152 bread-wheat cultivars from CIMMYT, Mexico were tested for resistance to these two stem rust isolates. Resistance to race TTKS was detected in all classes of wheat with the following frequencies: 16% of U.S. hard red spring wheat, 48% of the U.S. hard red winter wheat, 27% of U.S. soft red winter wheat, 50% of durum wheat, and 16% of CIMMYT spring bread wheat. Resistance in the hard red winter wheat was primarily due to Sr24, and resistance in the soft red winter wheat was primarily due to Sr36. Resistance to race TTKS due to SrTmp was present, but in a low frequency. Genes conferring resistance in the spring wheat are not known, but Sr24 may be present in some lines. The adult plant resistance of some selected wheat cultivars will be assessed in the field in Kenya.

Rice cultivars expressing the resistance (R) gene Pi-ta, have effectively prevented infection by blast isolates containing the corresponding avirulence gene AVR-Pita. Maintaining durable resistance is challenging due to the high degree of pathogenic variability and genetic instability of M. grisea. Genetic mapping demonstrated that AVR-Pita is tightly linked to a telomeric region. Evidence suggests that this location causes genetic transmogrifications within blast races like IE1k, consequently affecting host specificity. The objective of this study was to determine the functionality of AVR-Pita alleles in isolates of M. grisea found in the southern U.S. The AVR-Pita allele from the avirulent U.S. race IB-49, was amplified, cloned into a vector, and subsequently co-transformed with a hygromycin-containing plasmid pCB1004 into the race IE1k. A total of 45 recombinant isolates were generated and disease reactions were evaluated under controlled conditions. A single transformant consistently displayed the greatest level of blast resistance suggesting the restoration of avirulence to the virulent blast race IE1k.

Cryptococcus nodaensis OH 182.9 is an effective biocontrol agent for this disease. Development of a dried product of OH 182.9 would have potential advantages of ease of handling, favorable economics, and acceptance by end users. Isolate OH 182.9 was grown for 48 and 72 h in semi-defined complete liquid (SDCL) medium with carbon-to-nitrogen (C/N) ratios of 6.5:1, 9:1, 11:1, 15:1, and 30:1, and in SDCL C/N 30:1 media with varied carbon loadings of 7, 14, 21, and 28 g/liter. Total biomass production and cell survival at 15 days after freeze-drying were evaluated. Biomass production of OH 182.9 (CFU per milliliter) was not different for all cultivation time by medium C/N or carbon loading combinations. In general, cells harvested at 48 h survived freeze-drying better than those harvested at 72 h. Survival of freeze-dried cells was greatest for cells grown for 48 h in C/N 30:1 medium. Cells produced in C/N 6.5:1 medium generally exhibited the poorest survival. For the C/N 30:1 media, cells from 7 g/liter carbon loading medium harvested after 48 h had the best survival after freeze-drying. The difference in freeze-dried cell populations between superior and inferior treatments was typically 1 to 2 log units at 15 days after freeze-drying. The biomass of OH 182.9 produced in SDCL with varied C/N ratios and in SDCL C/N 30:1 media with differing carbon loadings was tested for biocontrol efficacy against FHB in greenhouse studies. The biomass harvested from SDCL C/N 9:1, 11:1, and 15:1 media after 48 h significantly reduced symptoms of FHB. None of the treatments with cells harvested at 72 h consistently reduced FHB severity (P less than or equal to 0.05). Cells grown in SDCL C/N 30:1 media with 7 and 14 g/liter carbon loading significantly reduced FHB disease severity. Cells harvested from SDCL C/N 9:1, 11:1, and 30:1 with 14 g/liter carbon increased the 100-kernel weight compared with the disease control. The potential of improving OH 182.9 product quality via management of the nutritional environment of the production medium is demonstrated in this study.

In the eastern United States, apple scab is managed almost exclusively through the regular application of fungicides. Management of the primary phase of disease is focused on preventing infection by ascospores. Management of secondary cycles of infection is largely dependent on how well primary infections were controlled. In this study, we used receiver operating characteristic curve analysis to evaluate how well mid-season assessments of the incidence of apple scab on cluster leaves, clusters (i.e., the whorl of cluster leaves), or immature fruit can serve as predictors of apple scab on harvested fruit (harvest scab) and whether these mid-season assessments of scab could be used reliably to manage scab under various damage thresholds. Results showed that assessment of scab on immature fruit was superior at predicting harvest scab than were assessments made on clusters or cluster leaves at all damage thresholds evaluated. A management action threshold of 7% scab incidence on immature fruit was identified by Youden's index as the optimal action threshold to prevent harvest scab incidence from exceeding 5%. Action thresholds could be higher or lower than 7% when economic assumptions were factored in to the decision process. The utility of such a predictor is discussed.

ALSD is caused by Xylella fastidiosa, a nutritionally fastidious bacterium. Single nucleotide polymorphisms (SNPs) in the 16S rRNA gene (16S rDNA) of X. fastidiosa strains were identified to characterize the bacterial population in infected trees. Genotype-specific SNPs were used to design primers for multiplex polymerase chain reaction assays of early passage cultures. Two genotypically distinct types of X. fastidiosa strains, G-type and A-type, coexist simultaneously in the same infected almond orchard. This was substantiated by restriction fragment length polymorphism analysis of a different genetic locus, RST31-RST33, which has previously been used to identify and differentiate X. fastidiosa strains. Furthermore, unique bacterial colony morphology was consistently associated with the A-type X. fastidiosa strains. To our knowledge, this is the first report of a mixed genotype infection of X. fastidiosa disease on the same location under natural environmental conditions. The concept of mixed genotype infection could affect the current epidemiological study based on the assumption that one genotype causes ALSD on one location and, therefore, the disease management strategy.

The bright vein-banding symptoms that confer the ornamental value to 'Variegata' clones are graft transmissible and can be eliminated after heat therapy and apical meristem culture. This observation led us to investigate the possibility that symptoms are virus-induced. Double-stranded RNA extracted from a 'Variegata' clone was cloned. One of the viruses identified was a member of the Closteroviridae family. This virus, designated Mint vein-banding associated virus, shares sequence similarities with all three genera of the family, making it an important link among the genera of the Closteroviridae. A detection protocol has been developed that readily detects the virus in other mint clones that exhibit vein-banding symptoms.

Inbred lines related to B73 are particularly susceptible to Phaeosphaeria leaf spot, whereas inbreds related to Mo17 are highly resistant. A previous study of the inheritance of resistance to Phaeosphaeria leaf spot in the cross B73 x Mo17 found that resistance is highly heritable and controlled by mostly additive gene action at three or four loci. In this study, we used 158 recombinant inbred (RI) lines derived from the cross B73 x Mo17 to map quantitative trait loci (QTL) governing resistance. The RI lines along with the parent inbred lines and the F sub(1) were evaluated for PLS resistance in replicated trials over two winter growing seasons in southern Florida. Using the composite interval mapping (CIM) function of PLABQTL software, five QTL on four different chromosomes were found to control PLS resistance in Mo17. In addition, the additive x additive interaction between two of these QTL was found to be significant. Our results are in close agreement with the previous study, where generation mean analysis was used to study the inheritance of resistance to PLS.

To determine whether adults of the citrus leafminer could act as vectors of citrus canker, we investigated two potential mechanisms for direct spread by leafminer adults using experimental microcosms. First, adult leafminers were raised on canker-infected foliage and were allowed to mate and lay eggs on healthy plants. These plants then were observed for development of citrus canker symptoms. In a second set of experiments, adults raised on healthy plants were given free access to canker-diseased plants during the period in which they mated and laid eggs on healthy plants. In all, 3,119 mines were produced by developing larvae on a total of 2,384 leaves examined for citrus canker symptoms. No symptoms of citrus bacterial canker disease were observed on any of the healthy test plants in 37 independent experimental trials conducted to test these two potential mechanisms of spread of citrus canker, and the pathogen was not recovered from insects exposed to symptomatic Rangpur lime plants. The upper limit on the rate of transmission was estimated to be less than 0.2% per oviposition event based on the binomial probability distribution. However, when adult P. citrella insects were artificially contaminated with high levels of X. axonopodis pv. citri, transmission to Rangpur lime plants with the induction of citrus canker was observed. This suggests that the ability of P. citrella to transmit X. axonopodis pv. citri is limited by the rate at which it can acquire inoculum from infected plants. The results support the conclusion that adult citrus leafminers are not efficient vectors for citrus canker bacteria, and the disease is unlikely to be spread this way.

Estimated concentrations of imazalil (IMZ) in potato-dextrose broth-Tris that caused 50% reduction in the germination of spores (ED sub(50)) of an IMZ-sensitive isolate M6R at pH 4, 5, 6, and 7 were 0.16, 0.11, 0.015, and 0.006 mu g/ml, respectively. ED sub(50) IMZ concentrations of an IMZ-resistant isolate D201 at pH 4, 5, 6, and 7 were 5.9, 1.4, 0.26, and 0.07 mu g/ml, respectively. The natural pH within 2-mm-deep wounds on lemon was 5.6 to 5.1 and decreased with fruit age. IMZ effectiveness to control green mold and its residues increased with pH.

This disease is caused by the xylem-limited bacterium Xylella fastidiosa, and this pathogen is transmitted by xylophagous insects including sharpshooter leafhoppers (Hemiptera: Cicadellidae) and spittlebugs (Hemiptera: Cercopidae). Among four orchards surveyed, enzyme-linked immunosorbent assay (ELISA) and bacterial isolation followed by polymerase chain reaction (PCR) were equally effective in detecting X. fastidiosa from ALS-symptomatic trees. Disease incidence varied among almond cultivars in each orchard, with the highest mean incidence and most severe symptoms frequently encountered in 'Sonora'. X. fastidiosa isolates consisted of mixtures of grape or "G-genotype" and almond or "A-genotype" strains present in surveyed orchards. The X. fastidiosa G-genotypes characterized from each orchard were associated with the most severely affected 'Sonora' trees in three of the four orchards. Both ordinary runs and simple randomization analyses revealed aggregations of ALS in three of the four orchards. Clusters of ALS-affected trees frequently occurred in the outermost orchard rows. Plots of semivariance in ALS incidence over distance varied in shape and magnitude among cultivars. Semivariance increased over distance in 'Sonora' and 'Carmel', indicating spatial dependence or aggregations of incidence best fit by a combination of spherical and linear models. These results document both random and aggregate patterns of ALS spatial distribution in selected orchards and further illustrate how cultivar susceptibility influences the distribution patterns of ALS incidence. Following the recent introduction and establishment of the glassy-winged sharpshooter, Homalodisca coagulata, the impact upon the epidemiology and spread of ALS is unknown.

The fruit were stored for 4 months at 1 degree C and then at 20 degree C for 2 weeks. Either heat or the antagonists reduced decay caused by C. acutatum, but a combination of the two was required to completely eliminate decay caused by this pathogen in most cases. Sodium bicarbonate alone or in combination with the antagonists had little effect on C. acutatum. The antagonists alone reduced decay caused by P. expansum but tended to be more effective when combined. Sodium bicarbonate increased the effectiveness of decay control by each antagonist alone or in combination. All of the treatments that included heat virtually eliminated decay caused by this pathogen.

Disease assessment is important for monitoring epidemics. Visual assessment (VA) is presently the only reliable means of detection. To investigate how VA of symptoms compared to image analysis we used digital images of 214 citrus leaves with a range of incidence and severity of citrus canker. Comparison of assessments by three plant pathologists (VA1-3) versus image analysis (IA) showed a poor relationship between lesion number and % area infected (R super(2) = 0.34-0.60). GLM analysis demonstrated no significant differences between IA and the visual assessors for lesion number (mean 16.3-18.7 lesions per leaf), but there were significant differences in the severity score for % area necrotic (3.3-5.4% mean area) but not for the total area infected (chlorotic+necrotic, 8.9-11.0% mean area), suggesting VA tended to overestimate the necrotic area, but was more accurate when assessing the whole infected area. The variability in VA for all raters was similar across all range categories of disease severity and lesion number. A sample of 53 leaves was converted to black/white images and IA/VA performed. The results were similar to using color images and both IA and VA provided comparable methods of assessment. IA appeared to provide an objective approach to assessing canker infected leaves.

Infection proceeds primarily via penetration of the adaxial surfaces of the palea and lemma tissues of a spikelet, although anthers also have been implicated in the infection process. The compounds choline and betaine are structurally similar and found in wheat anthers and other head tissues. These compounds can influence microbial and plant physiology via enhancing tolerance to environmental stresses including cold and osmotic. Several, but not all, reports suggest that these compounds also stimulate the growth of conidial germ tubes of G. zeae. Microbial colonists that rapidly utilize these compounds on wheat heads hypothetically would survive environmental stress to a greater extent and may reduce pathogen infection success by preemptively removing a growth signal used by the pathogen. When choline chloride was supplied as a sole carbon source in liquid culture, 122 choline metabolizing strains (CMS) from wheat anthers were identified out of 738 (16.5%) strains assayed. Twelve CMS with FHB biocontrol activity in greenhouse assays were selected for field testing. Four of 12 CMS reduced FHB symptoms at both of the sites and on both of the wheat varieties tested. In separately conducted tests, Cryptococcus nodaensis OH 182.9, a non-CMS yeast antagonist that was isolated from wheat anthers, maintained or increased in population even when applied to heads prior to anther extrusion. Additional studies on choline and betaine are needed to clarify the role of these compounds in FHB disease development.

The U.S. rice cultivar Katy was mutagenized by ethyl methane sulfonate (EMS), fast neutrons and gamma irradiation. For EMS, seeds were soaked in 0.4%, 0.8% and 1.2% EMS solutions for 6 hours and a total of 7,199 M sub(1)-derived lines was recovered. For fast neutrons, seven dosages of fast neutrons were applied and a total of 15,400 M sub(1) derived lines was recovered from treatments with 7.7 Gy, 26.3 Gy and 49.4 Gy. For gamma irradiation, 15 Gy, 20 Gy and 25 Gy were used and a total of 22,401 M sub(1) mutant lines was recovered. Greenhouse grown M sub(2) seedlings were screened for enhanced resistance to rice blast fungus Magnaporthe grisea. Thus far, a mutant population of a total of 45,000 M sub(1) derived lines has been established. In addition, a Sekiguchi-like lesion mimic mutant (LMM1) was identified and characterized. LMM1 is conditioned by a single recessive gene. Using greenhouse and laboratory assays we also showed that LMM1 possesses enhanced resistance to both M. grisea and sheath blight (Rhizoctonia solani). Progress on advancing this mutant population, mutant identification and characterization will be presented.

Achieving disease control through more integrated, sustainable disease management approaches is desirable. Cultural controls, such as crop rotations, cover crops, green manures and other organic amendments, as well as biological control approaches, can be important components in the management of soilborne diseases, but often provide only partial disease control. Recent research dealing with integrating biological and cultural management approaches suggests substantial interaction among approaches, as well as potential for enhanced disease control. Combining commercial biocontrol agents with the use of greensprouted potato seed to promote early emergence reduced problems with stem canker, black scurf, and common scab diseases. In other studies, the efficacy of biocontrol agents, microbial inoculants, or compost teas, were dependent on the cropping system, with biological amendments reducing disease in some rotations (such as barley/ryegrass), but not others (such as continuous potato).

Phytoplasmas are the causal pathogen of witches' broom. Witches' broom is known to exist in papaya, chestnut, grapevine, pine, and lime (Citrus aurantifolia). We report the presence of witches' broom in Valencia orange (C. sinensis) and mandarin (C. nobilis) and describe the genetic differences among the phytoplasmas found in Citrus from California, India, Jamaica, and Oman. In California, witches' broom are localized to one or several branches and nearby trees are not infected while in Oman, the severe symptoms kill the tree and the infection spreads to nearby trees. We have analyzed the genetic differences in the 16S sequences to determine if these are genetically different pathogens or if the pathogenicity is dependent on the environmental conditions of the different locations.

The fungicides thiabendazole (TBZ) and imazalil (IMZ), typically used at 2000 to 4000 micrograms per ml in citrus waxes, are applied primarily to control green mold, caused by Penicillium digitatum. The most effective approach to minimize fungicide use was to combine the existing approved fungicides with sodium bicarbonate (NaHCO sub(3)). The effectiveness of TBZ was maximized by employing an aqueous rather than wax TBZ solution, mild heating (41 degree C) of the solution, adding NaHCO sub(3), and completely immersing fruit, rather than drenching them, in the solution. These measures improved TBZ activity; even an isolate with TBZ-resistance was significantly controlled. In semi-commercial tests with naturally inoculated navel oranges from five groves, treatment with a solution containing only 350 micrograms per ml TBZ and 3% wt/vol NaHCO sub(3) reduced green mold incidence from 11% among untreated oranges to 2%. Similar approaches improved IMZ performance; even IMZ resistant isolates could be partially controlled.

Because of the 1 January 2005 methyl bromide (MB) phase out, cut flower growers need alternative treatments for pathogen and weed control. Field trials were established for 2 consecutive years to test various chemical combinations for Liatris production as an alternative to MB soil fumigation. The chemicals were applied by drip irrigation. In 2002, seven chemical were tested: chloropicrin, iodomethane, 1, 3-dichloropropene, sodium azide, metham sodium, furfural, allyl isothiocyanate, and metham sodium, all in various combinations. In 2003, dimethyl disulfide was added. At least 2 weeks following chemical application, the fields were planted with corms of Liatris spicata (L.) cv. Callilepsis. Most treatments reduced populations of Pythium spp. by 95% and Fusarium oxysporum by 50%. Metham sodium, furfural + metham sodium, sodium azide, and chloropicrin significantly reduced incidence of Liatris stem rot caused by Sclerotinia sclerotiorum. The most prevalent weeds were cheese-weed, mustard, knotweed, clover, and annual bluegrass. Weed control was not acceptable either year among any of the treatments. Viable alternatives to MB for cut flower production will require better treatments for weed control than was achieved in this study.

As many as 55% of the outplanted loblolly and 54% of the slash pines formed stem galls within one meter of the soil within a 3 year period. The progeny of known highly resistant families of both pine species generally did not form galls in the field. The overall means for all seedlings with galls in this study was 20% for loblolly and 19% for slash pines. Typical gall formation in susceptible seedlings was the same in the greenhouse and the field plantings. Galls developed in newly emergent shoots, which were examined by light microscopy. Histological examination of infected tissues from field and greenhouse proved similar to our earlier findings of resistant and susceptible reactions. These results raise questions about planting seedlings labeled gall-free.

Alfalfa plants were submitted from Iowa, Illinois, Minnesota, Wisconsin, and Ontario from 104 locations. DNA extracted from roots was used in PCR reactions with P. sclerotioides-specific primers. In Wisconsin, the pathogen was found in Shawano, Columbia, and Oconto County. In Minnesota, plants from seven counties tested positive for the pathogen including: Marshall, Otter Tail, Pennington, Red Lake, Sherburne, Wabasha, and Washington County. No positive plants were found in samples submitted from Illinois, Iowa or Ontario. Samples submitted in the spring of 2004 from fields with winter injury in Pierce Co. and St. Croix Co., WI and Winona Co., MN tested positive for the pathogen. This study suggests that the disease is found throughout Minnesota and may be associated with winter kill.

AN - 17446719; 6610462 AB - Animals are commonly regarded as the means of above-ground spread of the oak wilt fungus, Ceratocystis fagacearum. Squirrels, birds, and several insect groups have been incriminated as vectors of the pathogen, but little published data exists to support these assertions. Furthermore, no convincing evidence exists on the relative importance of any of the cited insects although speculations have been made. Theoretically, the most important vectors are those responsible for the highest incidence of successful transmission over short and long distances. Practically, however, it is not possible to identify the specific agent of transmission in retrospect since wilt symptoms first appear weeks to months after initial infection occurs. Circumstantial and/or more direct evidence related to successful transmission is therefore used to address the question of relative importance. Recent vector research on sap beetles has focused on the frequency of pathogen-contaminated adult species captured from receptive wounds and on seasonal flight activity of contaminated beetles in forest stands with oak wilt. Results have led to the hypothesis that Colopterus truncatus and Carpophilus sayi are the important sap beetle vectors in Minnesota. Our understanding of the relative importance of vector species throughout the oak wilt range is still rudimentary.

The fruit were stored for 4 months at 1 degree C. The antagonists survived and their populations increased in both air and controlled atmosphere storage (CA). The antagonists alone reduced decay but tended to be somewhat more effective when combined. Sodium bicarbonate increased decay control by each antagonist alone or combined. Storage under CA conditions also increased the effectiveness of each antagonist, alone or in combination. The only treatment that completely eliminated decay caused by this pathogen was the combination of the two antagonists and sodium bicarbonate on fruit stored under CA conditions. The proper combination of alternative control measures could help reduce our dependency on fungicides.

Previous work by Gadoury and colleagues has shown that grape berries from selected cultivars of Vitis vinifera gain resistance much earlier than previously expected, typically within 20 days post anthesis. The goal of this research is to determine the variation in duration of ontogenic susceptibility within Vitis spp. To accomplish this, three rows with high species diversity within the Plant Genetic Resources Unit's Vitis germplasm collection were selected to be inoculated with U. necator on a time-series based on the bloom date of the cluster. Disease was assessed macroscopically at harvest and disease was rated as percentage coverage of rachis, pedicel, and berry. Epidemiological data will be presented as will genomic and proteomic techniques being developed to uncover the molecular basis for ontogenic resistance.

Being transmitted by insect vectors and having a long incubation period, phytoplasma diseases exert significant impact on agriculture and forestry. Over the summers of 2003 and 2004, pronounced witches'-broom symptoms indicative of phytoplasma diseases were observed in plants of paper mulberry (Broussonetia papyrifera), Chinese wingnut (Pterocarya stenoptera), salt-cedar (Tamarix ramosissima), and a species related to fiber hemp (Cannabis sp.) grown in northern China. The diseased plants developed dense clusters of highly proliferating branches with shortened internodes; leaves on the affected branches were significantly smaller. Some branches and twigs of these plants suffered dieback. Results from nested polymerase chain reactions (PCR), performed by using phytoplasma-universal 16S rDNA primers, revealed that all diseased plants were infected by phytoplasma. Subsequent restriction fragment length polymorphism (RFLP) analysis and nucleotide sequence analysis of cloned near full-length 16S rRNA genes suggested that phytoplasmas present in these diseased plants belong to three different phytoplasma groups (16SrI, 16SrV, and 16SrX).

ER - TY - JOUR T1 - Fecal Coliform Transport as Affected by Surface Condition AN - 17378772; 6468094 AB - Land application of manure is recommended to recycle organic matter and nutrients, thus enhancing the soil quality and crop productivity. However, pathogens in manure may pose a human health risk if they reach potable or recreational water resources. The objective of this study was to observe and quantify the effects of vegetated filter strips (VFS) on surface and vertical transport of fecal coliform (FC) bacteria, surrogates for bacterial pathogens, released from surface-applied bovine manure. A two-sided lysimeter with 20% slope on both sides was constructed with a sandy loam soil on one side and a clay loam soil on the other. Each side of the lysimeter was divided into two subplots (6.0 x 6.4 m), one with grass and the other with bare soil. Plots were instrumented to collect runoff samples along a 6.0 m slope at three equidistant transects. Samples of runoff were also collected in a gutter at the edge of each plot. All plots were equipped with multi-sensor capacitance moisture probes to monitor water content through the soil profile. Bovine manure was applied at the top of each plot in a 30 cm strip. Rainfall was simulated at a 61 mm h super(- 1) intensity using a portable rainfall simulator. Surface runoff rate was measured and water quality sampled periodically throughout the simulation. Soil samples were taken at incremental depths (0-60 cm) after each simulation. Runoff (as % of total rainfall) decreased from 93% to 12% in the bare vs. vegetated clay loam plots and from 61% to 2% in the bare vs. vegetated sandy loam plots. The reduced runoff from vegetated plots decreased the surface transport of FC while increasing its vertical transport. The amount of FC in runoff (as % of applied) decreased from 68% to 1% in the bare vs. vegetated clay loam plots and from 23% to non-detectable levels in the bare vs. vegetated sandy loam plots. These data indicate that VFS can reduce surface transport of FC, even for slopes as high as 20%, especially in soils with high infiltration (e.g., sandy loam).

The objective of this article is to review current research in non-saline soils of the central U.S. to consider bulk soil electrical conductivity (EC sub(a)) as an assessment tool for: (1) tracking N dynamics, (2) identifying management zones, (3) monitoring soil quality trends, and (4) designing and evaluating field-scale experiments. The interpretation and utility of EC sub(a) are highly location and soil specific; soil properties contributing to measured EC sub(a) must be clearly understood. In soils where EC sub(a) is driven by NO sub(3)-N, EC sub(a) has been used to track spatial and temporal variations in crop-available N (manure, compost, commercial fertilizer, and cover crop treatments) and rapidly assess N mineralization early in the growing season to calculate fertilizer rates for site-specific management (SSM). Selection of appropriate EC sub(a) sensors (direct contact, electromagnetic induction, or time domain reflectometry) may improve sensitivity to N fluctuations at specific soil depths. In a dryland cropping system where clay content dominates measured EC sub(a), EC sub(a)-based management zones delineated soil productivity characteristics and crop yields. These results provided a framework effective for SSM, monitoring management-induced trends in soil quality, and appraising and statistically evaluating field-scale experiments. Use of EC sub(a) may foster a large-scale systems approach to research that encourages farmer involvement. Additional research is needed to investigate the interactive effects of soil, weather, and management on EC sub(a) as an assessment tool, and the geographic extent to which specific applications of this technology can be applied.

Performance of the model was tested on the Little River Experimental Watershed in Georgia and the Little Washita River Experimental Watershed in Oklahoma, both USDA-ARS watersheds. A long record of multi-gauge streamflow data on each of the watersheds was used for model calibration and validation. Model performance of the streamflow response in SWAT was assessed using a six-parameter manual calibration based on daily mass balance and visual inspection of hydro graphs and duration of daily flow curves, a six-parameter autocalibration method based on the daily sum of squares of the residuals after ranking objective function (referred to as SSQRauto6), a six-parameter method based on the daily sum of squares of residuals (SSQauto6), and an eleven-parameter method based on the daily sum of square of residuals (SSQauto11). Results show that for both watersheds, manual calibration generally outperformed the autocalibration methods based on percent bias (PBIAS) and simulation of the range in magnitude of daily flows. For the calibration period on Little River subwatershed F, PBIAS was 0.0%, -24.0%, -21.5%, and +29.0% for the manual, SSQRauto6, SSQauto6, and SSQauto11 methods, respectively. Based on the coefficient of efficiency (NSE), the SSQauto6 and SSQauto11 methods gave substantially better results than manual calibration on the Little River watershed. On the Little Washita watershed, however, the manual approach generally outperformed the automated methods, based on the NSE error statistic. Results of this study suggest that the autocalibration option in SWAT provides a powerful, labor-saving tool that can be used to substantially reduce the frustration and uncertainty that often characterize manual calibrations. If used in combination with a manual approach, the autocalibration tool shows promising results in providing initial estimates for model parameters. To maintain mass balance and adequately represent the range in magnitude of output variables, manual adjustments may be necessary following autocalibration. Caution must also be exercised in utilizing the autocalibration tool so that the selection of initial lower and upper ranges in the parameters results in calibrated values that are representative of watershed conditions.

ER - TY - JOUR T1 - Prevalence and genotypes of Giardia duodenalis in post-weaned dairy calves AN - 17370911; 6450026 AB - To determine the prevalence of Giardia genotypes in post-weaned dairy calves, fecal specimens were collected from 3 to 11-month-old dairy calves per farm on two farms in Vermont, New York, Pennsylvania, Maryland, Virginia, North Carolina, and Florida. Specimens cleaned of fecal debris and concentrated using CsCl density gradient centrifugation were stained and examined by immunofluorescence microscopy and also subjected to PCR and DNA sequence analysis. Overall, PCR provided more sensitive detection than IFA. Prevalence of Giardia infection, as detected by PCR ranged from 20% on NC-2 to 81% on VT-2, with an overall prevalence of 52% (237 positive samples out of 456 total). DNA sequence analysis of the 16S rRNA gene revealed 87% of the 237 Giardia isolates were Assemblage E, and 13% were Assemblage A although the prevalence of these genotypes varied greatly from farm to farm, with five farms having no Assemblage A Giardia. Therefore, Assemblage E was present in 45% of all animals tested and Assemblage A was present in 7% of the animals. Thus, while many of the calves were infected with a genotype that is not known to be infectious for humans, post-weaned calves on nine of 14 farms did harbor Assemblage A Giardia. Therefore calves should be considered as a potential source of human infectious cysts in the environment, with some farms representing a much higher risk than others.

Treated solutions designed to simulate typical concentrations in dairy manure lagoon water, contained initial concentrations of urea up to 750 ppm (mg L, super(-1), ), chloride from 100 to 400 ppm, and 2000 ppm NaHCO, sub(3), . Current from 0.6 to 2.5 A (34-141 A m, super(-2), ) was applied using oxide-coated titanium electrodes in a bench scale electrolysis device. Current and energy efficiencies of urea destruction increased with temperature and initial concentrations of chloride and urea. These parameters also affected the concentrations of oxidized chlorine species during treatment. Residual nitrogen was comprised of a constant fraction (0.07) of urea nitrogen oxidized to nitrate over the temperature range studied (16-34.5 , super([composite function (small circle)]), C). Chlorate was also formed as a byproduct of electrolysis.

We evaluated the interactive effect of manure C and N from nine dairy manures during a 176 days aerobic incubation. All of the manures had appreciable NH sub(4) content, and varied widely in fibrous C. The incubation was conducted using sandy loam (coarse-loamy, mixed, frigid, Typic Haplorthod) and silt loam (fine, illitic, non-acid, frigid, Aeric Epiaquepts) soils at 25 degree C and 60% water-filled pore space. There were clear differences in nitrate (NO sub(3)) accumulation over time, including manures that resulted in net nitrification and net immobilization. For both soils, the rate of nitrification at 7 and 56 days after application, and the amount of NO sub(3) accumulated at the end of the incubation (176 days) were strongly correlated (r = -0.88) with C: NH sub(4) and also to the ratio of neutral detergent fiber (NDF):NH sub(4) (r = -0.90). The addition of manure C also resulted in significant net immobilization, compared to addition of mineral N fertilizer alone. These studies demonstrate that increased understanding of manure C and N interactions may lead to improved prediction of manure PAN.

We studied a cationic organic polymer, Nalcolyte 8102, manufactured by Ondeo Nalco Co., Naperville, IL, USA. The material's active ingredient is a poly diallyldimethyl ammonium chloride (polyDADMAC), a proprietary quaternary polyamine. Surface-applied Nalcolyte 8102 and droplet energy were evaluated in laboratory and field studies for their effects on sugar beet emergence, soil penetration resistance (PR), and aggregate stability of two sprinkler irrigated, crust-prone silt loams in Idaho, U.S.A. In the laboratory, Nalcolyte 8102 at 1.1Mg active ingredient (a.i.) ha super(-1) was applied in 74,000L of solution ha super(-1) of wetted area; 5.4Mg a.i. ha super(-1) was applied in both 50,000 and 105,000Lha super(-1); and untreated water at 49,000Lha super(-1) was applied as a control. These treatments applied a. 7mm (7mm super(3)mm super(-2)) of a 5% by volume solution, 5mm of a 37% solution, a. 10mm of an 18% solution, and a. 5mm of untreated water, respectively. Later, at three field sites, Nalcolyte 8102 at 0.7 and 1.1Mg a.i. ha super(-1) were each applied in 74,000Lha super(-1) of solution (a. 7mm of a 3 and 5 solution, respectively) by spraying at planting onto two soils, a Durinodic Xeric Haplocalcid and a Xeric Haplodurid, with sugar beet planted to stand. In the laboratory, Nalcolyte 8102 at 1.1Mg ha super(-1) increased emergence 2.5-fold (32% to 80%) and reduced PR 3.5-fold (1.34 MPa to 0.39MPa) at 22days after planting (DAP), compared with controls. In the field, 0.7 and 1.1Mgha super(-1) increased emergence 1.2-fold (48.4 to about 58.3%) 50 DAP and increased aggregate stability after treatment 1.4-fold (68% to 97%) one DAP and 1.2-fold (76% to about 89%) 50 DAP, relative to an untreated control that received no water.

This study examined the effects of three tillage practices [no-till (NT), strip till (ST), and chisel till (CT)], four cover crops [legume (hairy vetch) (Vicia villosa roth), nonlegume (rye) (Secale cerealeL), hairy vetch/rye mixture, and winter weeds orno covercrop], and three N fertilization rates (0, 60-65, and 120-130 kg N ha super(-1)) on the amount of C sequestered in cotton lint (lint + seed), sorghum grain, their stalks (stems + leaves) and roots, and underlying soil from 2000 to 2002 in central Georgia, USA. A field experiment was conducted on a Dothan sandy loam (fine-loamy, kaolinitic, thermic, Plinthic Kandiudults). In 2000, C accumulation in cotton lint was greater in NT with rye or vetch/rye mixture but in stalks, it was greater in ST with vetch or vetch/rye mixture than in CT with or without cover crops. Similarly, C accumulation in lint was greater in NT with 60 kg N ha super(-1) but in stalks, it was greater in ST with 60 and 120 kg N ha super(-1) than in CT with 0 kg N ha super(-1). In 2001, C accumulation in sorghum grains and stalks was greater in vetch and vetch/rye mixture with or without N rate than in rye without N rate. In 2002, C accumulation in cotton lint was greater in CT with or without N rate but in stalks, it was greater in ST with 60 and 120 kg N ha super(-1) than in NT with or without N rate. Total C accumulation in the above- and belowground biomass in cotton ranged from 1.7 to 5.6 Mg ha super(-1) and in sorghum ranged from 3.4 to 7.2 Mg ha super(-1). Carbon accumulation in cotton and sorghum roots ranged from 1 to 14% of the total C accumulation in above- and belowground biomass. In NT, soil organic C at 0-10 cm depth was greater in vetch with 0 kg N ha super(-1) or in vetch/rye with 120-130 kg N ha super(-1) than in weeds with 0 and 60 kg N ha super(-1) but at 10-30 cm, it was greater in rye with 120-130 kg N ha super(-1) than in weeds with or without rate. In ST, soil organic C at 0-10 cm was greater in rye with 120-130 kg N ha super(-1) than in rye, vetch, vetch/rye and weeds with 0 and 60 kg N ha super(-1). Soil organic C at 0-10 and 10-30 cm was also greater in NT and ST than in CT. Since 5 to 24% of C accumulation in lint and grain were harvested, C sequestered in cotton and sorghum stalks and roots can be significant in the terrestrial ecosystem and can significantly increase C storage in the soil if these residues are left after lint or grain harvest, thereby helping to mitigate the effects of global warming. Conservation tillage, such as ST, with hairy vetch/rye mixture cover crops and 60-65 kg N ha super(-1) can sustain C accumulation in cotton lint and sorghum grain and increase C storage in the surface soil due to increased C input from crop residues and their reduced incorporation into the soil compared with conventional tillage, such as CT, with no cover crop and N fertilization, thereby maintaining crop yields, improving soil quality, and reducing erosion.
