AB Intercropping alleys in agroforestry provides an income source until the tree crop produces harvestable yields. However, cultivation of annual crops decreases soil organic matter and increases soil erosion potential, especially on sloping landscapes. Perennial crops maintain a continuous soil cover, increase water infiltration, reduce soil erosion, and improve overall soil quality. The objective of this on-farm study was to assess the effects of a perennial legume, kura clover (Trifolium ambiguum M. Bieb.), on soil quality in a recently established pecan (Carya illinoinensis Wangenh. C. Koch) orchard. The pecankura clover agroforestry practice was established on deep loess soils of the Missouri River hills landscape. These silt loams are on 2-20% slopes and can be highly erosive. Kura clover, introduced as the alley crop 5 years after pecan planting, was selected based on its perennial growth habit, nitrogen-fixing ability, winter hardiness, high forage quality, and soil conservation properties. Kura clover was seeded in 2001 and harvested for hay annually beginning 2003. Soil quality indicators of total organic C, total N, water-stable aggregates, and selected soil enzymes were determined on surface soil samples collected annually after kura clover establishment. Soil organic C and activities of soil enzymes increased compared with cultivated and grass pasture control soils by the eighth year of establishment. Water-stable aggregation improved by 50% and surface soil shear strength improved significantly (P < 0.05) in alleys compared with control sites. Results illustrate that kura clover as the alley-cropped component improved soil fertility and biological activity through increased organic matter and improved soil structure, and yielded high quality forage valuable for the cattle-feeding operation. Kura clover maintained or improved soil quality, reduced soil erosion potential, and benefited pecan growth by providing a source of soil nitrogen and improving soil structure for adequate water infiltration and aeration.

AB The hybrid origin of Ilex x wandoensis C. F. Mill. & M. Kim was studied by polymerase chain reaction (PCR) using taxa-specific primers, restriction fragment length polymorphism (RFLP) analysis of the internal transcribed spacer 2 (ITS2) regions, and sequence analysis of PCR amplicons of the ITS region. Five accessions of I. integra Thunb., three accessions of I. cornuta Lindl. & Paxton and 22 accessions of I. x wandoensis, tentatively characterized based on morphological characters, were selected and subjected to PCR analysis. Amplified products of the selected accessions were sequenced. Significant variations were observed in leaf morphology of I. x wandoensis accessions based on the presence of single or multiple teeth and cuneate or rounded base of the leaf blade. Based on the PCR amplifications, sequence and RFLP analysis using HhaI and HaeIII restriction enzymes, the hybrid origin of I. x wandoensis was confirmed. Some accessions appeared to be introgressant and either crossed back to I. integra or to I. cornuta based on the RFLP polymorphisms. Analysis of the ITS2 region of the nuclear ribosomal DNA (nrDNA) using primers specific to certain taxon or taxa, and RFLP analysis of PCR amplicons proved to be useful tools to study the nature of interspecific hybridization and introgressions in complement with morphological characters.

AB Iris series Hexagonae is a small, monophyletic complex of five species and associated hybrid populations, popularly known as the "Louisiana irises." The Hexagonae alliance of Iris has been recognized as a textbook case of introgressive hybridization on the basis of numerous studies in Louisiana. In light of field observations of phenotypic heterogeneity among Florida populations, we investigated genetic variation within and among 37 populations of Iris series Hexagonae from Florida, seven from Louisiana, and one from Texas with 19 microsatellite loci. We wished to test the hypothesis that the Lake Wales Ridge and Polk Uplands of Florida, which remained above sea level maxima during the early Pleistocene, might be the sites of origin for all extant iris populations in Florida and possibly the series Hexagonae in its entirety. We also hypothesized that phenotypic heterogeneity observed in Florida iris would be reflected in patterns of allelic diversity. Finally, we wished to seek evidence of Native American influence on the present distribution of iris in Florida. Most populations display clonality, including three populations that are predominantly one or two clones. Levels of gene diversity are high and the populations are highly differentiated, although 19 exhibit significant homozygote excess. The majority of genetic variation occurs within populations. Genetic distance resolves three large clusters. One unites the southernmost populations with those from north-central Gulf coastal Florida. A second encompasses southwest Gulf coastal populations. If three compound repeat loci are dropped from the data, these two clusters are united. The third group joins populations derived from the Central Highlands of peninsular Florida, which are genetically isolated from all other peninsular Florida populations, with populations of Iris fulva, Iris brevicaulis, Iris giganticaerulea, and Iris hexagona s.s., supporting recognition of the latter two as distinct species. Model-based Bayesian clustering supports high population differentiation (K = 22) and isolation of Central Highlands populations, and it resolves the terminal clusters of the genetic distance topology. Isolation by distance is significant yet weak because of genetic distance relationships that contradict biogeographic expectations. We propose that the Lake Wales Ridge and Polk Uplands, which constituted the Wicomico shoreline during an early Pleistocene interglacial inundation, functioned as refugia for series Hexagonae. Moreover, we suggest that Florida iris populations occupying high, dry habitats close to the Central Highlands ridges represent relicts of once-larger populations that adapted to the more xeric condition during the last glacial maximum. These populations have a distinctive floral phenotype and are related to species of Hexagonae iris outside of peninsular Florida. Excessively clonal populations may have been deliberately cultivated by Native Americans, which may also have influenced the connection between southern and north-central Florida populations, but there is insufficient evidence to validate this hypothesis. Many populations test positively for recent bottlenecks, which we attribute primarily to founder effects, given the low migration rates of the species and the high degree of population differentiation as well as the Holocene geological history of the Florida peninsula. We present evidence of peripatric divergence in series Hexagonae iris and suggest that this may function as a significant generator of species diversity in the group.

AB Allopolyploidization is considered an essential evolutionary process in plants that could trigger genomic shock in allopolyploid genome through activation of transcription of retrotransposons, which may be important in plant evolution. Two retrotransposon-based markers, inter-retrotransposon amplified polymorphism and retrotransposon-microsatellite amplified polymorphism and a microsatellite-based marker, inter simple sequence repeat were employed to investigate genomic changes in early generations of a newly synthesized allotetraploid Cucumis x hytivus Chen & Kirkbride (2n = 4x = 38) which was derived from crossing between cultivated cucumber C. sativus L. (2n = 2x = 14) and its wild relative C. hystrix Chakr. (2n = 2x = 24). Extensive genomic changes were observed, most of which involved the loss of parental DNA fragments and gain of novel fragments in the allotetraploid. Among the 28 fragments examined, 24 were lost while four were novel, suggesting that DNA sequence elimination is a relatively frequent event during polyploidization in Cucumis. Interestingly, of the 24 lost fragments, 18 were of C. hystrix origin, four were C. sativus-specific, and the remaining two were shared by both species, implying that fragment loss may be correlated with haploid DNA content (genome size) of diploid parents. Most changes were observed in the first generation after polyploidization (S(1)) and stably inherited in the subsequent three generations (S(2)-S(4)), indicating that genomic changes might be a rapid driving force for the stabilization of allotetraploids. Sequence analysis of 11 of the 28 altered DNA fragments showed that genomic changes in the allotetraploid occurred in both coding and non-coding regions, which might suggest that retrotransposons inserted into genome randomly and had a genome-wide effect on the allotetraploid evolution. Fluorescence in situ hybridization (FISH) analysis revealed a unique distribution of retrotransposon and/or microsatellite flanking sequences in mitotic and meiotic chromosomes, where the preferential FISH signals occurred in the centromeric and telomeric regions, implying that these regions were the possible hotspots for genomic changes.

AB The results of a survey of Doryctinae (Hymenoptera: Braconidae), excluding species of Heterospilus Haliday, at Konza Prairie near Manhattan, Kansas are reported. Eleven sites representing prairie and woodland/wetland areas, including gallery forest, were sampled in 2001 and 2005 using Malaise and canopy traps. Topographic trap placement included lowland, midslope, and upland areas. Twenty-four species were collected, including 18 in 2001 and 16 in 2005. Twenty-three of the 24 species were collected from the woodland/wetland sites, including 19 from gallery forest sites; five of the 24 species were collected from the prairie sites. Rhaconotus fasciatus (Ashmead) was the most abundant species in 2001 (n = 13); Callihormius bifasciatus (Ashmead) and Coiba jeffersoni Kula were the most abundant species in 2005 (n = 10). The following new species are described: Doryctes xanthogaster Kula and Marsh, Doryctes xanthosoma Kula and Marsh, Doryctinus zolnerowichi Kula and Marsh, and Pambolidea dollari Kula and Marsh. Glyptocolastes caryae (Ashmead), status revised is removed from synonymy with Glyptocolastes rugulosus (Cresson), the type species for Doryctinus Roman. The latter species is transferred to Acrophasmus Enderlein, resulting in Acrophasmus as a new synonym of Doryctinus. Synonymy of the aforementioned genera results in the following nomenclatural changes: Doryctinus amazonicus (Roman), new combination; Doryctinus arizonensis (Marsh), new combination; Doryctinus atriventris (Cresson), new combination; Doryctinus butleri (Marsh), new combination; Doryctinus costaricensis (Marsh), new combination; Doryctinus erugatus (Marsh), new combination; Doryctinus exilis (Enderlein), new combination; Doryctinus ferrugineus (Marsh), new combination; Doryctinus gauldi (Marsh), new combination; Doryctinus immigrans (Beardsley), new combination; Doryctinus maeandrius (Enderlein), new combination; Doryctinus marshi Greenbaum, revised combination; Doryctinus rubronotum (Marsh), new combination; Doryctinus rugulosus (Cresson), revised combination; Doryctinus scobiciae (Marsh), new combination; and Doryctinus secundus (Muesebeck and Walkley), new combination. Doryctes infuscus Marsh is a new synonym of Doryctes rufipes (Provancher), Pioscelus wichitus (Viereck) is a new synonym of Pioscelus borealis (Ashmead), and Rhaconotus graciliformis (Viereck) is a new synonym of R. fasciatus. The following species are first records for Kansas: C. bifasciatus, Dendrosoter sulcatus Muesebeck, D. rufipes, D. ferrugineus, Ecphylus hypothenemi Ashmead, Ecphylus rohweri Muesebeck, Ontsira mellipes (Ashmead), and Rhaconotus canadensis Marsh.

AB Oak forests throughout North America are declining due to changes in disturbance regimes that have led to increased competition from other tree and shrub species. We evaluated associations between oak regeneration, the occurrence of two common invasive shrubs (common buckthorn (Rhamnus cathartica L.) and Tartarian honeysuckle (Lonicera tatarica L.)), and forest edges in oak forests in a portion of the midwestern United States where bur (Quercus macrocarpa Michx.), red (Quercus rubra L.), and white oak (Quercus alba L.) were historically dominant. We found poor recruitment of oaks in comparison to other, more shade-tolerant tree species. Results further revealed a strong stand-scale association between bur oak, open canopy conditions, high soil nutrient levels, and the presence of common buckthorn and Tartarian honeysuckle; these same site characteristics were disassociated with red and white oak. Within red and white oak stands, however, the presence of the invasive shrubs was more pronounced near forest edges. While oak recruitment is hampered throughout stands, our research suggests that predominant constraints may vary based on soil and light gradients found along forest edges.

AB The impact of settlement era fires on Appalachian forests was substantial, but whether these fires affected the extent of fire-adapted ridgetop plant communities is poorly understood. Here we present fire history and stand structure of an Appalachian ridgetop (Pike Knob, West Virginia) based on fire scars from three species (Pinus pungens Lamb., Pinus resinosa So land., and Quercus rubra L.) and stand structure from two species (P. pungens and P. resinosa). Our research objectives are to determine (i) the degree to which the fire frequency on Pike Knob was affected by European American settlement (similar to 1780-1900) and (ii) how the history of fire on Pike Knob shaped the current age structure of P. resinosa and P. pungens. All three species documented fire activity beginning in the mid- to late 1800s and continuing into the middle of the 20th century, when pasture lands were most active. The majority of P. pungens and P. resinosa established during or shortly after the similar to 85-year period of fires (1868-1953), suggesting a strong influence of past land use on current forest composition. Ridgetop pine communities have been resilient to both the absence of fire and frequent fire, indicating that pine communities will also be resilient to modern fire management, whether fire is excluded or re-introduced.

AB Many semi-arid coniferous forests in western North America have reached historically unprecedented densities over the past 150 years and are dominated by shade-tolerant trees. Silvicultural treatments generally open the canopy but may not restore shade-intolerant species. We determined crossover-point irradiance (CPI) (light at which the height growth rank of pairs of species changes) for seedlings in Sierra Nevada mixed-conifer forest and used these to interpret light environments produced by fuels-reduction thinning and group selection with reserved large trees. Nine of 21 species pairs had well-defined CPIs. The CPI of the most common shade-tolerant and intolerant species (white fir (Abies concolor (Gordon & Glendl.) Lindl. ex Hildebr.) and ponderosa pine (Pinus ponderosa Douglas ex P. Lawson & C. Lawson)) was 22.5 mol.m(-2).day(-1) or 41% of full sun. Median understory irradiance increased from 9.2 mol.m(-2)day(-1) (17% full sun) in pretreatment forest to 13 mol.m(-2).day(-1) (24% full sun) in lightly and 15.5 mol.m(-2).day(-1) (28% full sun) in moderately thinned stands and 37 mol.m(-2).day(-1) (67% full sun) in group-selection openings. We estimate that 5%-20% of ground area in lightly to moderately thinned stands would have enough light to favor shade-intolerant over shade-tolerant growth compared with 89% of ground area in group-selection openings. The CPI provides a tool to assess regeneration implications of treatment modification such as increasing heterogeneity of thinning to enhance regeneration or reserving large trees in group-selection openings to maintain wildlife habitat.

AB Colored potatoes (Solanum tuberosum L.) are a significant source of antioxidants from polyphenols, carotenoids and ascorbic acid. In this study, the retention of total antioxidants in fresh colored potatoes and processed potato flakes prepared as potential ingredients for snack foods was studied. Total antioxidant capacity, total phenolics and total anthocyanins were higher in purple potato flesh compared with those from red, yellow and white potato cultivars. Peeled purple potatoes were blanched and dehydrated by freeze drying (FD), drum drying and refractance window drying to prepare potato flakes. Results showed no significant losses in total antioxidant capacity and total phenolic content in flakes in all drying methods obtained under study. However, 45, 41 and 23% losses in total anthocyanins content were observed in potato flakes after FD, drum drying and refractive window drying, respectively. Colored potatoes could provide an excellent source of antioxidant-rich ingredient for the production of nutritionally enhanced food products.

DT Article
ID PEELABILITY; ANATOMY; DAMAGE
AB Peeling outcomes of processing tomatoes were predicted using multivariate analysis of magnetic resonance (MR) images. Tomatoes were obtained from a whole-peel production line. Each fruit was imaged using a 7-tesla MR system, and a multivariate data set was created from 28 different images. After imaging, the fruits were individually tagged and processed in a pilot peeling system. An expert grader then assessed the peeling outcome for each fruit; outcomes included whole peel,some skin attached and seven others. The multivariate analysis techniques of partial least squares-discriminant analysis (PLS-DA) and soft independent modeling of class analogy (SIMCA) were used to predict peeling outcome from the 28 MR images. The PLS-DA model for the whole peel (best) outcome correctly classified 81% of the fruit that were in this category. The SIMCA model performed well for rejecting non-whole peel fruit but did not perform as well for identification of whole peel fruit.

ID EXTRUSION-COOKING; FLOUR
AB The operating costs associated with twin-screw extrusion cooking of various foods are fixed for a given size and production capacity for any class of products; the greater percentage of costs arise from the choice of ingredients and the product end use. For example, extruder texturized whey proteins (TWP) is a new class of ingredients with expanded functionality and range of applications such as in protein-enriched snacks. The cost to produce twin-screw extruder TWP was estimated to range from $0.67/kg to $11.63/kg depending on the protein concentration of the whey and the other ingredients. Extrusion cooking was also applied to a type of raw product purchased by the U.S. government for emergency feeding overseas under the Food for Peace program (P.L. 480 Title II program). The food, a mixture of corn, soy protein concentrate and soybean oil, and minerals blend (cornsoy blend) could be produced from $0.45 to $0.55/kg.

AB Currently, carbon credit prices frequently do not reflect the type and location of offset projects. Because of the social image and ancillary benefits, buyers may place higher value on credits sourced from certain types of projects such as urban forestry. This study surveyed carbon credit buyers participating in the Chicago Climate Exchange to assess their preferences for credits from various offset projects. Specifically, it evaluated the desirability of carbon credits sourced from urban forestry projects and analyzed buyers' preferences, motivations, and attitudes toward a price premium for credits from urban forests. Results indicate that the buyers are largely interested in knowing the type and location of offset projects. Locally generated credits were strongly preferred to those produced farther away, and credits sourced from urban forestry projects were more desirable than those sourced from other common projects currently in the market, such as methane capture or agriculture. Buyers indicated environmental and social benefits, offset quality, environmental responsibility, and public image as motivations for preferring credits sourced from urban forestry projects, for which they were also willing to pay a modest price premium. Furthermore, significant differences in preferences and willingness to pay were observed between buyers with different corporate goals, emission levels, and geographical scope of operation.

AB Directly or indirectly, positively or negatively, climate change will affect all sectors and regions of the United States. The impacts, however, will not be homogenous across regions, sectors, population groups or time. The literature specifically related to how climate change will affect rural communities, their resilience, and adaptive capacity in the United States (U. S.) is scarce. This article bridges this knowledge gap through an extensive review of the current state of knowledge to make inferences about the rural communities vulnerability to climate change based on Intergovernmental Panel on Climate Change (IPCC) scenarios. Our analysis shows that rural communities tend to be more vulnerable than their urban counterparts due to factors such as demography, occupations, earnings, literacy, poverty incidence, and dependency on government funds. Climate change impacts on rural communities differs across regions and economic sectors; some will likely benefit while others lose. Rural communities engaged in agricultural and forest related activities in the Northeast might benefit, while those in the Southwest and Southeast could face additional water stress and increased energy cost respectively. Developing adaptation and mitigation policy options geared towards reducing climatic vulnerability of rural communities is warranted. A set of regional and local studies is needed to delineate climate change impacts across rural and urban communities, and to develop appropriate policies to mitigate these impacts. Integrating research across disciplines, strengthening research-policy linkages, integrating ecosystem services while undertaking resource valuation, and expanding alternative energy sources, might also enhance coping capacity of rural communities in face of future climate change.

AB A field experiment was conducted during three cropping seasons to compare weed control and cotton yield provided by conventional (CV), glufosinate-resistant (LL), and glyphosate-resistant (RR) weed management systems under standard (102 cm) and narrow (38 cm) row spacing grown in conventional and conservation tillage systems. The conventional tillage and/or CV cotton received a PRE application of pendimethalin. The CV, LL, and RR cotton varieties received two POST applications of pyrithiobac, glufosinate, and glyphosate, respectively, at two- and four-leaf cotton growth stages. A final (LAYBY) application of trifloxysulfuron was applied to 38-cm row cotton while a LAYBY POST-directed spray of prometryn plus MSMA was used in 102-cm row cotton. The LL and RR weed management systems controlled at least 97% of large crabgrass, Palmer amaranth, sicklepod, and smallflower morningglory, while the CV system controlled 89, 73, and 87 to 98% of large crabgrass, smallflower morningglory, and Palmer amaranth, respectively. Sicklepod control increased from 85% in 102-cm rows to 95% in 38-cm rows in the CV herbicide system. Yellow nutsedge and pitted morningglory control exceeded 98% and was not affected by tillage, row spacing, or weed management system. Cotton yield was not affected by row spacing any year, by tillage in 2005, or by weed management system in 2004 and 2005. In 2006, yield in the RR weed management system was 27 and 24% higher than LL and CV weed management systems, respectively. In 2004, yield of conventional tillage cotton was 18% higher than conservation tillage cotton, but in 2006 the yield in conservation tillage was 12% higher than conventional tillage.

TI Differential Response of Liverwort (Marchantia polymorpha) Tissue to
POST-Applied Quinoclamine
SO WEED TECHNOLOGY

DE Chlorophyll; Bryophyta; herbicide absorption; nursery crops;

ID CHLOROPHYLL; DICAMBA
AB Quinoclamine is used in Europe, and was under evaluation in the Unites States for the control of liverwort in nursery crops. Liverwort is a nonvascular, chlorophyll-containing plant that can be problematic in greenhouse and nursery crops. POST-applied quinoclamine controls liverwort. However, liverwort structures vary in their sensitivity to POST-applied quinoclamine. Specifically, archegonial receptacles (female) are much more tolerant of quinoclamine than either antheridial receptacles (male) or thalli (leaflike structures). A series of studies were conducted to, first, document the degree of differential sensitivity between tissues to quinoclamine, and second, to determine the basis of this differential sensitivity. The dose that results in 50% of the population being controlled (150) of antheridial receptacles and juvenile thalli were estimated to be 1.60 and 1.27 kg.ha(-1), respectively. The 150 of archegonial receptacles could not be estimated, but exceeded 10.45 kg.ha(-1). Chlorophyll content varied between liverwort tissues, but the content did not correlate to quinoclamine sensitivity. Absorption of (14)C after application of radiolabeled quinoclamine was less in archegonial receptacles than in either antheridial receptacles or thalli. Scanning electron microscopy of the surface of the liverwort tissues revealed that archegonial receptacles had smaller pores (equivalent to stomata in higher plants) than either antheridial receptacles or thalli. The tolerance of archegonial receptacles to quinoclamine can be partially, but not exclusively, attributed to reduced absorption. This reduced absorption may be attributed to the limited pore size and less total pore area of the archegonial receptacles.

AB We conducted a field experiment in 2007 and 2008 and repeated it in a separate field in 2008 and 2009 to test the effectiveness of two herbicides applied at two different times on weed control during switchgrass establishment. At 4 and 6 wk after switchgrass planting (WAP), sulfosulfuron was applied at 0.04 and 0.07 kg ai ha(-1) with nonionic surfactant and quinclorac was applied at 0.28, 0.42, and 0.56 kg ai ha(-1) with methylated seed oil. Herbicides applied at 4 WAP tended to be more effective than at 6 WAP. Sulfosulfuron provided greater control of smooth pigweed; however, quinclorac provided greater control of yellow foxtail, a grass weed that has traditionally been difficult to control with herbicides in switchgrass. Average yellow foxtail control was 73, 87, and 93% for quinclorac at 0.28, 0.42, and 0.56 kg ha(-1), respectively, compared to 62 and 60% for sulfosulfuron at 0.04 and 0.07 kg ha(-1), respectively. Switchgrass injury (chlorosis and height reduction relative to the untreated control) was observed, but most symptoms were not detectable by 8 wk after treatment (WAT) for most treatments. Plots that received quinclorac at 0.56 kg ha(-1) at 6 WAP tended to have relatively low weed biomass and high total aboveground yield in the establishment year and relatively high total aboveground yield in the year after establishment.

AB Field studies were conducted in 2008 in Ontario, OR and Paterson, WA to determine the effect of simulated glyphosate drift on 'Ranger Russet' potato, including visual injury, shikimic acid accumulation, and tuber yield. Glyphosate was applied at 8.5, 54, 107, 215, and 423 g ae ha(-1); which corresponds to 0.01, 0.064, 0.126, 0.254, and 0.5 of the lowest recommended (846 g ha(-1)) single application dose for glyphosate-resistant corn and sugar beet. Glyphosate was applied when potato plants were at 10-cm height, stolon hooking, tuber initiation, or bulking stage. The greatest visual foliar injury was observed when glyphosate was applied at a dose of 54 g haT/ha or greater and potato plants were at the hooking stage. The lowest foliar injury was observed when glyphosate was applied to potato plants at the bulking stage. The I(50) glyphosate dose at 42 d after treatment (DAT) was estimated to be 167 g ha(-1) for potatoes sprayed at the hooking stage. The corresponding glyphosate dose to result in 50% injury, for potatoes sprayed at tuber initiation, 10-cm height, and bulking stages were 129%, 338%, and 438%, respectively, greater than hooking stage. The U.S. No.1 potato yield was inversely related to vine injury and shikimic acid accumulation. Shikimic acid accumulation increased when glyphosate was applied at 107 g ha(-1) or greater. U.S. No.1 potato yield was reduced by 46% and 84% relative to the untreated control (55 and 76 T/ha) when glyphosate was applied at 107 g ha(-1) to plants in the booking stage at Ontario and Paterson, respectively. Tuber yields at both sites were lowest when glyphosate was applied at hooking and tuber initiation stages.

AB Acremonium zeae, one of the most prevalent fungal colonists of preharvest corn, possesses a suite of hemicellulolytic activities including xylanase, xylosidase, and arabinofuranosidase. Two enzymes with arabinofuranosidase activity were purified from cell-free culture supernatants of A. zeae grown on oat spelt xylan. A 47 kDa enzyme (AF47) was optimally active at 37 degrees C and pH 6.0, and had a specific activity for 4-nitrophenyl-alpha-L-arabinofuranoside (4NPA) of 6.2 U/mg. A 30 kDa enzyme (AF30) was optimally active at 50 degrees C and pH 4.5, and had a specific activity for 4NPA of 12.4 U/mg. AF47 hydrolyzed 4-nitrophenyl-beta-D-xylopyranoside, 4-nitrophenyl-beta-D-glucopyranoside, and 4-nitrophenyl-beta-D-cellobioside, as well as producing reducing sugars from corn fiber, wheat, and oat spelt arabinoxylan. AF30 had little detectable activity on the 4-nitrophenyl substrates, except for 4NPA, but activity on arabinoxylans from corn fiber, wheat, and oat spelt was at least 7-fold higher than AF47, with specific activities of 109, 358, and 153 U/mg, respectively. A combination of the two enzymes released 61 and 88% of the total arabinose from corn fiber and wheat arabinoxylans. The arabinofuranosidases produced by A. zeae may have industrial application for the enzymatic hydrolysis of recalcitrant lignocellulosic feedstocks such as corn fiber and wheat straw.

AB Wheat flour and different packaging surfaces (cardboard, flour bag, muslin bag, paper bag, pallet wrap, plastic overwrap, polyethylene) were exposed to aerosol formulations of either 1% active ingredient (AI) pyrethrin (synergized with piperonyl butoxide)+ 33.6% (AI) methoprene or 3% (AI) pyrethrin + 33.6% AI methoprene. The mixture was formulated as specified on the insecticide labels to give a 100 to 1 ratio of active ingredient pyrethrin to methoprene. Residual bioassays were conducted every two weeks for 16 weeks post-exposure to the aerosol by placing four-week-old larvae of the red flour beetle, Tribolium castaneum (Herbst), or the confused flour beetle, Tribolium confusum (Jacqueline duVal), on treated flour or a treated packaging surface with untreated flour added. T castaneum was clearly the more susceptible of the two species. Less than 2% of T. castaneum larvae exposed to aerosol-treated flour or packaging surfaces emerged as normal adults, regardless of the pyrethrin concentration. Most of the T. castaneum larvae on treated flour did not advance to the pupal stage because they were either developmentally arrested or died as larvae. They were able to develop further on the treated packaging surfaces, but still could not emerge as adults. T. confusum larvae exposed to aerosol-treated flour or packaging surfaces were able to develop to the pupal or adult stage. Emergence of normal-appearing adults from T. confusum larvae exposed on the packaging surfaces treated with 1% pyrethrin + methoprene gradually increased (range of 29.7 +/- 2.9 to 49.0 +/- 6.7%, depending on the surface), whereas adult emergence of larvae exposed to treated flour peaked at 10 weeks post-exposure. However, when T. confusum was exposed to 3% pyrethrin + methoprene treated flour or packaging surfaces, adult emergence was reduced. Overall there were few significant differences attributable to the individual packaging surfaces. Published by Elsevier Ltd.

AB The movement and temperature preference of Rhyzopertha dominica was determined in a 56 cm diameter cylinder with 9 cm high sides containing 19.9 kg of hard red winter wheat. Two temperature gradients were tested over a 24 h period: 42 to 20 degrees C and 24 to 20 degrees C with the cooler temperature being on the periphery of the cylinder. No preference existed when there was no temperature gradient. Beetles preferred the moderate temperature region of the cylinder in the 42 to 20 degrees C gradient, but avoided the highest temperature region. In the 24 to 20 degrees C gradient, insects did not move very much during the 24 h period. When a longer duration was used (96 h) for the 24 to 20 degrees C gradient, there were significantly more insects in the warmest center region of the gradient compared to the middle or outer regions. Compared to other stored grain Coleoptera, such as Cryptolestes ferrugineus, R. dominica appears to move more slowly through the grain into preferred temperature regions. Published by Elsevier Ltd.

A strikingly disjunct (approximately 4,000 km) population was recently discovered in Bolivia, representing the first record of this species in South America, and the first species in the section growing in both North and Central America and in South America. Our maximum entropy analysis of 19 climatic variables matches the occurrence of the South American locality with great precision. It demonstrates the strong predictive quality of this procedure and suggests similar localities where this species may be found, especially along the eastern slopes of the Andes in the Yungas region of southern Peru and Bolivia. In addition, the presence of S. morelliforme in South America adds to emerging data from yet other sources to question long-held hypotheses of the origin of section Petota in North and Central America.

AB The compact (dwarf) plant architecture is an important trait in cucumber (Cucumis sativus L.) breeding that has the potential to be used in once-over mechanical harvest of cucumber production. Compact growth habit is controlled by a simply inherited recessive gene cp. With 150 F(2:3) families derived from two inbred cucumber lines, PI 308915 (compact vining) and PI 249561 (regular vining), we conducted genome-wide molecular mapping with microsatellite (simple sequence repeat, SSR) markers. A framework genetic map was constructed consisting of 187 SSR loci in seven linkage groups (chromosomes) covering 527.5 cM. Linkage analysis placed cp at the distal half of the long arm of cucumber Chromosome 4. Molecular markers cosegregating with the cp locus were identified through whole genome scaffold-based chromosome walking. Fine genetic mapping with 1,269 F2 plants delimited the cp locus to a 220 kb genomic DNA region. Annotation and function prediction of genes in this region identified a homolog of the cytokinin oxidase (CKX) gene, which may be a potential candidate of compact gene. Alignment of the CKX gene homologs from both parental lines revealed a 3-bp deletion in the first exon of PI 308915, which can serve as a marker for marker-assisted selection of the compact phenotype. This work also provides a solid foundation for map-based cloning of the compact gene and understanding the molecular mechanisms of the dwarfing in cucumber.

AB Tan spot, caused by Pyrenophora tritici-repentis, is a major foliar disease of wheat worldwide. Host plant resistance is the best strategy to manage this disease. Traditionally, bi-parental mapping populations have been used to identify and map quantitative trait loci (QTL) affecting tan spot resistance in wheat. The association mapping (AM) could be an alternative approach to identify QTL based on linkage disequilibrium (LD) within a diverse germplasm set. In this study, we assessed resistance to P. tritici-repentis races 1 and 5 in 567 spring wheat landraces from the USDA-ARS National Small Grains Collection (NSGC). Using 832 diversity array technology (DArT) markers, QTL for resistance to P. tritici-repentis races 1 and 5 were identified. A linear model with principal components suggests that at least seven and three DArT markers were significantly associated with resistance to P. tritici-repentis races 1 and 5, respectively. The DArT markers associated with resistance to race 1 were detected on chromosomes 1D, 2A, 2B, 2D, 4A, 5B, and 7D and explained 1.3-3.1% of the phenotypic variance, while markers associated with resistance to race 5 were distributed on 2D, 6A and 7D, and explained 2.2-5.9% of the phenotypic variance. Some of the genomic regions identified in this study correspond to previously identified loci responsible for resistance to P. tritici-repentis, offering validation for our AM approach. Other regions identified were novel and could possess genes useful for resistance breeding. Some DArT markers associated with resistance to race 1 also were localized in the same regions of wheat chromosomes where QTL for resistance to yellow rust, leaf rust and powdery mildew, have been mapped previously. This study demonstrates that AM can be a useful approach to identify and map novel genomic regions involved in resistance to P. tritici-repentis.

AB Five Australian potyviruses, passion fruit woodiness virus (PWV), passiflora mosaic virus (PaMV), passiflora virus Y, clitoria chlorosis virus (ClCV) and hardenbergia mosaic virus (HarMV), and two introduced potyviruses, bean common mosaic virus (BCMV) and cowpea aphid-borne mosaic virus (CAbMV), were detected in nine wild or cultivated Passiflora and legume species growing in tropical, subtropical or Mediterranean climatic regions of Western Australia. When ClCV (1), PaMV (1), PaVY (8) and PWV (5) isolates were inoculated to 15 plant species, PWV and two PaVY P. foetida isolates infected P. edulis and P. caerulea readily but legumes only occasionally. Another PaVY P. foetida isolate resembled five PaVY legume isolates in infecting legumes readily but not infecting P. edulis. PaMV resembled PaVY legume isolates in legumes but also infected P. edulis. ClCV did not infect P. edulis or P. caerulea and behaved differently from PaVY legume isolates and PaMV when inoculated to two legume species. When complete coat protein (CP) nucleotide (nt) sequences of 33 new isolates were compared with 41 others, PWV (8), HarMV (4), PaMV (1) and ClCV (1) were within a large group of Australian isolates, while PaVY (14), CAbMV (1) and BCMV (3) isolates were in three other groups. Variation among PWV and PaVY isolates was sufficient for division into four clades each (I-IV). A variable block of 56 amino acid residues at the N-terminal region of the CPs of PaMV and ClCV distinguished them from PWV. Comparison of PWV, PaMV and ClCV CP sequences showed that nt identities were both above and below the 76-77% potyvirus species threshold level. This research gives insights into invasion of new hosts by potyviruses at the natural vegetation and cultivated area interface, and illustrates the potential of indigenous viruses to emerge to infect introduced plants.

AB The in situ esterification/transesterification of algal biomass lipids to produce FAME for potential use as biodiesel was investigated. Commercial algal biomass was employed, containing 20.9 wt% hexane extractable oil. This consisted of 35.1 wt% free fatty acids (FFA), 18.2 wt% TAG, and 8.8 wt% MAG, accounting for 62.1% of the extractable material. Other constituents of the hexane extractable material, accounting for 37.9% of the extracts, were not further characterized. The predominant fatty acids in the oil were palmitic (42.4 wt%), oleic (30.6 wt%), linoleic (22.8 wt%), and linolenic (16.1 wt%). Small amounts of 10-keto 16:0 and 10-OH 16:0 fatty acids were also present. Statistical experimental design was employed to coordinately examine the effects of the amounts of methanol, sulfuric acid, and reaction temperature (23-658C) on the yield of FAME in 2 h reactions. Three methods of feedstock preparation were examined - as received, oven dried, and water-washed/dried. For all feedstocks conditions could be identified which were predicted to yield greater than 90% maximum theoretical FAME production. Oven drying the feedstock reduced the amount of methanol required, with 83% of maximum yield obtained at a methanol/fatty acid molar ratio of 220:1 (4 mL methanol/g substrate). Water washing the biomass did not reduce the methanol required for high level transesterification.
Practical applications: In biodiesel production by the conventional method of alkali-catalyzed transesterification of a refined vegetable oil/the combination of feedstock and process costs threatens the economic viability of biofuel production. In situ esterification/transesterification is a method for producing biodiesel wherein a lipid-bearing material is directly treated with reagents that catalyze fatty acid alkyl ester production from FFA and acylglycerols. By eliminating the need to isolate and refine the feedstock lipid, this approach to biodiesel production eliminates some of the processing steps required by contemporary methods. This could provide a welcome reduction in the cost of biodiesel production. There is presently considerable interest in the possibility of biofuel production from algal biomass. This study describes the application and optimization of in situ transesterification to a lipid-bearing algal biomass. Application of this technology could facilitate the economical production of biodiesel from algal biomass.

AB Identification and serotyping of Shiga toxin-producing Escherichia calf during foodborne outbreaks can aid in matching clinical, food, and environmental isolates when trying to identify the source of illness and ultimately food contamination. Herein we describe a Luminex microbead-based suspension array to identify the O serogroup of the ten most clinically relevant STECs: O26, O45, O91, O103, O111, O113, O121, O128, O145, and O157. The use of PCR followed by Luminex xMAP (R) technology enables the detection of multiple analytes in a single multiplex reaction with high throughput capabilities. One hundred and fourteen STEC isolates were correctly identified with no false positives among forty-six other organisms using this assay. Assay performance was tested in multiple laboratories using a panel of eleven different STEC serogroups on the BioPlex 200 and MAGPIX instruments. The STEC microbead-based suspension array can be performed in a 96-well plate format for high throughput screening in less than 4 h. Furthermore, it is expandable, allowing for the addition of O serogroups should the need arise. Published by Elsevier B.V.

AB In mobile animals, movement behavior can maximize fitness by optimizing access to critical resources and minimizing risk of predation. We sought to evaluate several hypotheses regarding the effects of landscape structure on American marten foraging path selection in a landscape experiencing forest perforation by patchcut logging. We hypothesized that in the uncut pre-treatment landscape marten would choose foraging paths to maximize access to cover types that support the highest density of prey. In contrast, in the post-treatment landscapes we hypothesized marten would choose paths primarily to avoid crossing openings, and that this would limit their ability to optimally select paths to maximize foraging success. Our limiting factor analysis shows that different resistant models may be supported under changing landscape conditions due to threshold effects, even when a species' response to landscape variables is constant. Our results support previous work showing forest harvest strongly affects marten movement behavior. The most important result of our study, however, is that the influence of these features changes dramatically depending on the degree to which timber harvest limits available movement paths. Marten choose foraging paths in uncut landscapes to maximize time spent in cover types providing the highest density of prey species. In contrast, following landscape perforation by patchcuts, marten strongly select paths to avoid crossing unforested areas. This strong response to patch cutting reduces their ability to optimize foraging paths to vegetation type. Marten likely avoid non-forested areas in fragmented landscapes to reduce risk of predation and to benefit thermoregulation in winter, but in doing so they may suffer a secondary cost of decreased foraging efficiency.

AB The phytic acid (myo-inositol hexakisphosphate or InsP(6)) content of seed crops is important to their nutritional quality. Since it represents 75 +/- 10% of the total seed phosphorus (P), phytic acid is also important regarding the management of P in agricultural production. A low-phytate F5 line, No. T-2-250-4-20, was selected from the progeny of a cross between the low-phytate soybean line CX1834 and the Japanese commercial cultivar Tanbakuro. This line and its parents were grown in a field nursery, and the growth characteristics, phytate accumulation, and processing suitability for tofu were evaluated. At full maturity, the weight of seeds per plant of line T-2-250-4-20 was 5.2- and 1.3-fold higher than that of CX1834 and Tanbakuro, respectively. The amount of phytate-phosphorus as a percentage of the total P content in seeds was 23% in line T-2-250-4-20-34, 30% in CX1834, and 69% in Tanbakuro. No significant difference was observed among the three cultivars/lines in their seed magnesium (Mg), potassium (K), crude protein, and sugar. However, the calcium (Ca), crude fat and ash contents in seeds of line T-2-250-4-20-34 and Tanbakuro was lowered compared to that of CX1834. The breaking stress of tofu was estimated employing a rheometer with a decreasing concentration of the coagulant magnesium chloride (MgCl(2)), starting at 15.7 mmol L(-1). In tofu made from Tanbakuro, the concentration of MgCl(2) required to achieve the maximum breaking stress was 12.6 mmol however, it was 9.5 mmol L(-1) for tofu made from T-2-250-4-20-34 and CX1834. The tofu made from Tanbakuro was soft and broke at 6.3 mmol L(-1) MgCl(2), but, in line T-2-250-4-20-34, harder tofu was made with lower MgCl(2), concentrations. No difference was observed among the cultivars/lines in the SOS-PAGE patterns of protein in soymilk. These results indicate that we have developed a low-phytate soybean with adequate productivity, and confirmed that tofu made from the low-phytate T-2-250-4-20-34 soybean becomes coagulated and harder at a lower MgCl(2) concentration than that from high-phytate soybean cultivars.

AB Sustainable feedstock harvest strategies are needed to ensure bioenergy production does not irreversibly degrade soil resources. The objective for this study was to document corn (Zea mays L.) grain and stover fraction yields, plant nutrient removal and replacement costs, feedstock quality, soil-test changes, and soil quality indicator response to four stover harvest strategies for continuous corn and a corn-soybean [Glycine max. (L.) Merr.] rotation. The treatments included collecting (1) all standing plant material above a stubble height of 10 cm (whole plant), (2) the upper-half by height (ear shank upward), (3) the lower-half by height (from the 10 cm stubble height to just below the earshank), or (4) no removal. Collectable biomass from Treatment 2 averaged 3.9 (+/- 0.8) Mg ha(-1) for continuous corn (2005 through 2009), and 4.8 (+/- 0.4) Mg ha(-1) for the rotated corn (2005, 2007, and 2009). Compared to harvesting only the grain, collecting stover increased the average N-P-K removal by 29, 3 and 34 kg ha(-1) for continuous corn and 42, 3, and 34 kg ha(-1) for rotated corn, respectively. Harvesting the lower-half of the corn plant (Treatment 3) required two passes, resulted in frequent plugging of the combine, and provided a feedstock with low quality for conversion to biofuel. Therefore. Treatment 3 was replaced by a "cobs-only" harvest starting in 2009. Structural sugars glucan and xylan accounted for up to 60% of the chemical composition, while galactan, arabinan, and mannose constituted less than 5% of the harvest fractions collected from 2005 through 2008. Soil-test data from samples collected after the first harvest (2005) revealed low to very low plant-available P and K levels which reduced soybean yield in 2006 after harvesting the whole-plant in 2005. Average continuous corn yields were 21% lower than rotated yields with no significant differences due to stover harvest. Rotated corn yields in 2009 showed some significant differences, presumably because soil-test P was again in the low range. A soil quality analysis using the Soil Management Assessment Framework (SMAF) with six indicators showed that soils at the continuous corn and rotated sites were functioning at an average of 93 and 83% of their inherent potential, respectively. With good crop management practices, including routine soil-testing, adequate fertilization, maintenance of soil organic matter, sustained soil structure, and prevention of wind, water or tillage erosion, a portion of the corn stover being produced in central Iowa, USA can be harvested in a sustainable manner.

AB An open-economy equilibrium model is derived to investigate the effects of energy policy on the U.S. economy, with emphasis on corn-based ethanol. A second best policy of a fuel tax and ethanol subsidy is found to approximate fairly closely the welfare gains associated with the first best policy of an optimal carbon tax and tariffs on traded goods. The largest economic gains to the U.S. economy from these energy policies arise from their impact on U.S. terms of trade, particularly in the oil market. Conditional on the current fuel tax, an optimal ethanol mandate is superior to an optimal ethanol subsidy.

AB In scale-up, the potential of ethanol production by dilute sulfuric acid pretreatment using corncob was investigated. Pretreatments were performed at 170 A degrees C with various acid concentrations ranging from 0% to 1.656% based on oven dry weight. Following pretreatment, pretreated biomass yield ranged from 59% to 67%. More than 90% of xylan was removed at 0.828% of sulfuric acid. At same pretreatment condition, the highest glucose yield obtained from pretreated biomass by enzymatic hydrolysis was about 76%, based on a glucan content of 37/100 g. In hydrolysate obtained by pretreatment, glucose concentration was low, while xylose concentration was significantly increased above 0.368% of sulfuric acid. At 1.656% of sulfuric acid, xylose and glucose concentration was highest. In subsequent, fermentation with hydrolysate, maximal ethanol yield was attained after 24 h with 0.368% of sulfuric acid. The fermentation efficiency of hydrolysate obtained by enzymatic hydrolysis reached a maximum of 75% at an acid charge of 0.368%.

TI Scale-up of Ethanol Production from Winter Barley by the EDGE (Enhanced
Dry Grind Enzymatic) Process in Fermentors up to 300 l
SO APPLIED BIOCHEMISTRY AND BIOTECHNOLOGY
LA English
DT Article
DE Ethanol fermentation; Winter barley; beta-Glucans; Process scale-up;
Biorefinery
AB A fermentation process, which was designated the enhanced dry grind enzymatic (EDGE) process, has recently been developed for barley ethanol production. In the EDGE process, in addition to the enzymes normally required for starch hydrolysis, commercial beta-glucanases were used to hydrolyze (1,3)(1,4)-beta-d-glucans to smaller molecules, thus reducing the viscosity of the mash to levels sufficiently low to allow transport and mixing in commercial equipment. Another enzyme, a developmental beta-glucosidase, then was used to hydrolyze the resulting oligomers to glucose, which subsequently was fermented to produce additional ethanol. The EDGE process was developed with Thoroughbred, a winter hulled barley, using a shake flask model. To move toward commercialization, it is necessary to prove that the developed process would be applicable to other barley varieties and also to demonstrate its scalability. Experiments were performed in 7.5, 70, and 300-l fermentors using Thoroughbred and Eve, a winter hull-less barley. It was shown that the process was scalable for both barley varieties. Low levels of glucose throughout the course of the fermentations demonstrated the high efficiency of the simultaneous saccharification and fermentation process. Final ethanol concentrations of 14% (v/v) were achieved for initial total solids of 28.5-30% (w/w), which gave an ethanol yield of 83-87% of the theoretical values. The distillers dried grains with solubles co-products contained very low levels of beta-glucans and thus were suitable for use in feed formulations for all animal species.

AB The increasing use of treated wastewater for irrigation heightens the importance of accurate monitoring of water quality. Chromogenic media, because they are easy to use and provide rapid results, are often used for detection of Escherichia coli in environmental samples, but unique levels of organic and inorganic compounds alter the chemistry of treated wastewater, potentially hindering the accurate performance of chromogenic media. We used MI agar and molecular confirmatory methods to assess false-positive identification of E. coli in treated wastewater samples collected from municipal utilities, an irrigation holding pond, irrigated soils, and in samples collected from storm flows destined for groundwater recharge. False-positive rates in storm flows (4.0%) agreed closely with USEPA technical literature but were higher in samples from the pond, soils, and treatment facilities (33.3%, 38.0%, and 48.8%, respectively). Sequencing of false-positive isolates confirmed that most were, like E. coli, of the family Enterobacteriaceae, and many of the false-positive isolates were reported to produce the beta-D-glucuronidase enzyme targeted by MI agar. False-positive identification rates were inversely related to air temperature, suggesting that seasonal variations in water quality influence E. coli identification. Knowledge of factors contributing to failure of chromogenic media will lead to manufacturer enhancements in media quality and performance and will ultimately increase the accuracy of future water quality monitoring programs.

AB Genome-wide expression studies transformed the field of transcriptomics and made it feasible to study global gene expression in extraordinary detail. These new methods have revealed an enhanced view of the transcriptional landscape and have yielded many biological insights. It is increasingly clear that the prokaryotic transcriptome is much more complex than once thought. Recent advances in microbial transcriptome analyses are highlighted in this review. Areas of progress include the development of optimized techniques that minimize the abundance of ribosomal RNAs in RNA samples as well as the development of novel methods to create transcriptome libraries. Advances such as these have led to a new emphasis in areas such as metatranscriptomics and single cell gene expression studies.

AB The rapid increase in residential land area in the United States has raised concern about water pollution associated with nitrogen fertilizers. Nitrate (NO(3)(-)) is the form of reactive N that is most susceptible to leaching and runoff; thus, a more thorough understanding of nitrification and NO(3)(-) availability is needed if we are to accurately predict the consequences of residential expansion for water quality. In particular, there have been few assessments of how the land use history, housing density, and age of residential soils influence NO(3)(-) pools and fluxes, especially at depth. In this study, we used 1 m deep soil cores to evaluate potential net nitrification and mineralization, microbial respiration and biomass, and soil NO(3) and NH(4)(+) pools in 32 residential home lawns that differed by previous land use and age, but had similar soil types. These were compared to eight forested reference sites with similar soils. Our results suggest that a change to residential land use has increased pools and production of reactive N, which has clear implications for water quality in the region. However, the results contradict the common assumption that NO(3)(-) production and availability is dramatically higher in residential soils than in forests in general. While net nitrification (128.6 +/- 15.5 mg.m(-2).d(-1) vs. 4.7 +/- 2.3 mg.m(-2).d(-1); mean +/- SE) and exchangeable NO(3)(-) (3.8 +/- 0.5 g/m(2) vs. 0.7 +/- 0.3 g/m(2)) were significantly higher in residential soils than in forest soils in this study, these measures of NO(3)(-) production and availability were still notably low, comparable to deciduous forest stands in other studies. A second unexpected result was that current homeowner management practices were not predictive of NO(3)(-) availability or production. This may reflect the transient availability of inorganic N after fertilizer application. Higher housing density and a history of agricultural land use were predictors of greater NO(3)(-) availability in residential soils. If these factors are good predictors across a wider range of sites, they may be useful indicators of NO(3)(-) availability and leaching and runoff potential at the landscape scale.

AB Bald eagles (Haliaeetus leucocephalus) have been utilized as a biosentinel of aquatic ecosystem health in the Great Lakes Region since the early 1960s. Bald eagle populations have been monitored at Voyageurs National Park (VNP), Minnesota, since 1973. For the past 20 years, researchers have collected feathers from nestling bald eagles to assess their dietary exposure to mercury (Hg) on Rainy, Kabetogama, and Namakan lakes in VNP. Mercury is an environmental pollutant with both natural and anthropogenic sources, and negatively affects many species of wildlife. In a previous study, geometric mean concentrations of Hg in feathers of nestling bald eagles were greater at VNP (20 mg/kg Dry Weight (DW)) than in nestling feathers from other Great Lakes subpopulations (similar to 7 mg/kg DW), for the period 1985-1989. Current geometric mean concentrations have declined by 77.4% since 1989 at VNP. While all samples from 1985 to 1989 had detectable concentrations of Hg, 10% of current samples had concentrations below the reportable detection limit (0.001 mg/kg DW, n = 180). The major lakes at VNP are impounded, and Hg concentrations also declined greatly after the lake level stabilization order by the International Joint Commission was implemented in 1999. Mercury concentrations in feathers of nestling bald eagles from 1989 to 2010 ranged from ND (<0.001) to 34.97 mg/kg DW. The highest single concentration in a nestling was from Namakan Lake in 2010. The five-year geometric means for Rainy, Kabetogama, and Namakan lakes for 2006-2010 were 6.08, 1.07, and 5.56 mg/kg DW (n = 28, n = 32, n = 27) respectively. Although Hg concentrations in feathers of nestlings greatly declined after the change in water level management in 1999 and are lower than 1989 concentrations, recent samples suggest a gradual increase. Continued monitoring of nestling feather concentrations will be essential to assess this increase, to determine the source of Hg, to determine if there are changes to methylation potential, and to evaluate and optimize water level management.

AB Elymus L. is the largest and most complex genus in the Triticeae tribe of grasses with approximately 150 polyploid perennial species occurring worldwide. We report here the first genetic linkage map for Elymus. Backcross mapping populations were created by crossing caespitose Elymus wawawaiensis (EW) (Snake River wheatgrass) and rhizomatous Elyntus lanceolauts (EL) (thickspike wheatgrass) to produce F(1) interspecific hybrids that were then backcrossed to the same EL male to generate progeny with segregating phenotypes. EW and EL are both allotetraploid species (n = 14) containing the St (Pseudoroegneria) and H (Hordeum) genomes. A total of 387 backcross progeny from four populations were genotyped using 399 AFLP and 116 EST-based SSR and STS markers. The resulting consensus map was 2574 cM in length apportioned among the expected number of 14 linkage groups. EST-based SSR and STS markers with homology to rice genome sequences were used to identify Elymus linkage groups homoeologous to chromosomes 1-7 of wheat. The frequency of St-derived genome markers on each linkage group was used to assign genome designations to all linkage groups, resulting in the identification of the seven St and seven H linkage groups of Elymus. This map also confirms the alloploidy and disomic chromosome pairing and segregation of Elymus and will be useful in identifying QTLs controlling perennial grass traits in this genus.

AB Dasypyrum villosum (L.) Candargy, a wild relative of bread wheat (Triticum aestivum L.), is the source of many agronomically important genes for wheat improvement. Production of compensating Robertsonian translocations (cRobTs), consisting of D. villosum chromosome arms translocated to homoeologous wheat chromosome arms, is one of the initial steps in exploiting this variation. The cRobTs for D. villosum chromosomes 1V, 4V, and 6V have been reported previously. Here we report attempted cRobTs for wheat - D. villosum chromosome combinations 2D/2V, 3D/3V, 5D/5V, and 7D/7V. The cRobTs for all D. villosum chromosomes were recovered except for the 2VS and 5VL arms. As was the case with the 6D/6V combination, no cRobTs involving 2D/2V chromosomes were recovered; instead, cRobT T2BS.2VL involving a non-targeted chromosome was recovered. All cRobTs are fertile, although the level of spike fertility and hundred kernel weight (HKW) varied among the lines. The set of cRobTs involving 12 of the 14 D. villosum chromosomes will be useful in wheat improvement programs. In fact, among the already reported cRobTs, T6AL.6VS carrying the Pm21 gene is deployed in agriculture and many useful genes have been reported on other cRobTs including resistance to stem rust race UG99 on T6AS.6VL.

AB This paper presents the spatial distribution of photosynthetic active radiation (PAR) using an atmospheric radiative transfer model under terrain impacts. The potential of the model for improved understanding of PAR impacts on ecosystem dynamics is demonstrated with the aid of MODIS (Moderate-resolution Imaging Spectroradiometer) data, using the Haihe Plain of China as a case study. Various types of MODIS data were aggregated in support of the modeling work at the regional scale. Findings clearly indicate that terrain factors do affect the estimation of instantaneous PAR significantly. Different relationships between PAR and elevation may be classified based on positive correlation, negative correlation, and no correlation. In addition, while there are different relations between PAR and slope, there is no significant correlation between PAR and aspect.

AB Landscape assessment of soil moisture is critical to understanding the hydrological cycle at the regional scale and in broad-scale studies of biophysical processes affected by global climate changes in temperature and precipitation. Traditional efforts to measure soil moisture have been principally restricted to in situ measurements, so remote sensing techniques are often employed. Hyperspectral sensors with finer spatial resolution and narrow band widths may offer an alternative to traditional multispectral analysis of soil moisture, particularly in landscapes with high spatial heterogeneity. This preliminary research evaluates the ability of remotely sensed hyperspectral data to quantify soil moisture for the Little River Experimental Watershed (LREW), Georgia. An airborne hyperspectral instrument with a short-wavelength infrared (SWIR) sensor was flown in 2005 and 2007 and the results were correlated to in situ soil moisture values. A significant statistical correlation (R(2) value above 0.7 for both sampling dates) for the hyperspectral instrument data and the soil moisture probe data at 5.08 cm (2 inches) was determined. While models for the 20.32 cm (8 inches) and 30.48 cm (12 inches) depths were tested, they were not able to estimate soil moisture to the same degree.

ID ENERGY BALANCE APPROACH; MAPPING EVAPOTRANSPIRATION; FLUXES; INDEX;
MODEL; SCALE; PREDICTION; IMAGERY
AB High-resolution evapotranspiration (ET) maps can assist demand-based irrigation management. Development of high-resolution daily ET maps requires high-resolution land surface temperature (LST) images. Earth-observing satellite sensors such as the Landsat 5 Thematic Mapper (TM) and MODerate resolution Imaging Spectroradiometer (MODIS) provide thermal images that are coarser than simultaneously acquired visible and near-infrared images. In this study, we evaluated the TsHARP downscaling technique for its capability to downscale coarser LST images using finer resolution normalized difference vegetation index (NDVI) data. The TsHARP technique was implemented to downscale seven coarser scale (240, 360, 480, 600, 720, 840, and 960 m) synthetic images to a 120 m LST image. The TsHARP was also evaluated for downscaling a coarser 960 m LST image to 240 m to mimic MODIS datasets. Comparison between observed 120 m LST images and 120 m LST images downscaled from coarser 240, 360, 480, 600, 720, 840, and 960 m images yielded root mean square errors of 1.0, 1.3, 1.5, 1.6, 1.7, 1.8, and 1.9 degrees C, respectively. This indicates that the TsHARP method can be used for downscaling coarser (960 m) MODIS-based LST images using finer Landsat (120 m) or MODIS (240 m)-derived NDVI images. However, the TsSHARP method should be evaluated further with real datasets before using it for an operational ET remote sensing program for irrigation scheduling purposes.

AB Free-ranging wildlife, such as feral swine (Sus scrota), harbor a variety of diseases that are transmissible to livestock and could negatively impact agricultural production. Information is needed regarding the exposure and infection rates of Mycobacterium bovis and many other diseases and parasites in feral swine occurring in the Texas border region. Our main objective was to determine exposure rates and possible infection rates of M. bovis in feral swine by opportunistically sampling animals from the Texas border region. From June to September 2010, we obtained samples from 396 feral swine and tested 98 samples for M. bovis by histopathology and mycobacteriologic culture. We found no evidence of M. bovis infection. We believe that it is important to periodically and strategically sample feral swine for M. bovis in high-risk areas of the United States because they are capable of becoming reservoirs of the disease.

AB We tested the Rabond V-RG (R) recombinant oral rabies vaccine for its response in Arctic fixes (Vulpes lagopus), the reservoir of rabies virus in the circumpolar North. The vaccine, which is currently the only licensed oral rabies vaccine in the United States, induced a strong antibody response and protected foxes against a challenge of 500,000 mouse intracerebral lethal close 50% of an Arctic rabies virus variant. However, one unvaccinated control fox survived challenge with rabies virus, either indicating a high resistance of Arctic foxes to rabies infection or a previous exposure that induced immunity. This preliminary study suggested that Raboral V-RC vaccine may be efficacious in Arctic foxes.

ID WATER-TABLE MANAGEMENT; HYDROLOGICAL VARIABILITY; QUALITY; PHOSPHORUS;

AB Typical controlled drainage structures in drainage ditches provide drainage management strategies for isolated temporal periods. Innovative, low-grade weirs are anticipated to provide hydraulic control on an annual basis, as well as be installed at multiple sites within the drainage ditch for improved spatial biogeochemical transformations. This study provides evidence toward the capacity of low-grade weirs for nutrient reductions, when compared to the typical controlled drainage structure of a slotted riser treatment. Three ditches with weirs were compared against three ditches with slotted risers, and two control ditches for hydraulic residence time (HRT) and nutrient reductions. There were no differences in water volume or HRT between weired and riser systems. Nutrient concentrations significantly decreased from inflow to outflow in both controlled drainage strategies, but there were few statistical differences in N and P concentration reductions between controlled drainage treatments. Similarly, there were significant declines in N and P loads, but no statistical differences in median N and P outflow loads between weir (W) and riser (R) ditches for dissolved inorganic phosphate (W, 92%; R, 94%), total inorganic phosphate (W, 86%; R, 88%), nitrate-N (W, 98%; R, 96%), and ammonium (W, 67%; R, 85%) when nutrients were introduced as runoff events. These results indicate the importance of HRT in improving nutrient reductions. Low-grade weirs should operate as important drainage control structures in reducing nutrient loads to downstream receiving systems if the hydraulic residence time of the system is significantly increased with multiple weirs, as a result of ditch length and slope.

AB Incidence and severity of Huanglongbing (HLB) disease were assessed in Apr. 2010 among eight citrus cultivars representing diverse scion types growing in commercial groves in Florida's Indian River region, an area with a high incidence of HLB. In each grove, 20 trees of each cultivar were rated for visual HLB symptoms and leaves were collected for quantitative polymerase chain reaction quantification of Candidatus Liberibacter asiaticus (CLas), the presumptive causal agent of H LB. There was a strong correlation between HLB rating and CLas titer (titer represented by Ct, r(2) = 0.37 and 0.40, for whole tree and leaf sample, respectively, both with P < 0.0001) across all cultivars and groves. Although incidence and severity of HLB varied considerably among the groves, scion-specific differences were apparent, even when analyses excluded potentially confounding grove effects. 'Temple' tangor showed the most consistently low incidence of HLB symptoms and CLas titer; in contrast, 'Murcott' tangor and 'Minneola' tangelo had the highest incidence of HLB symptoms and highest CLas titer. These results suggest useful resistance to HLB with reduced symptoms and reduced CLas titer may be found in conventional scion cultivars and further work is needed to assess this potential and its commercial value.

AB Powdery mildew of cucurbits, incited by Podosphaera xanthii (Castagne) Braun & Shishkoff (syn. Sphaerotheca fuliginea auct. p.p.), is an economically important foliar disease. which is now common in watermelon [Citrullus lanatus (Thunb.) Mastum. & Nakai]. This disease occurs in all watermelon-growing areas and can reduce yields by up to 30%. Finding and breeding for resistance to this disease is important to reduce dependence on fungicides and to use in combination with fungicides to limit the spread of fungicide-resistant P. xanthii. This is the first English report that race 2WF of P. xanthii can infect watermelon. It is the prevalent race of watermelon powdery mildew in Beijing.

AB Each year, over 16 million tons of poultry litter is produced in the United States. Federal and state regulations now limit the amount of poultry litter that can be land-applied, making it difficult to store and dispose of poultry litter. The objective of this study was to evaluate composted poultry litter (CPL) as a fertilizer source for bedding plants at various rates in comparison with commercially available inorganic fertilizers in regard to plant growth and nutrient leaching. Two experiments were conducted to evaluate use of CPL as fertilizer for landscape annual bedding plants. Petunia spp. 'Celebrity Red' and Verbena hybrida 'Quartz Scarlet' were planted in raised beds simulating an urban landscape. Before planting, 10 inorganic fertilizer or CPL treatments were incorporated into the raised beds, including Peafowl (R) brand garden-grade fertilizer 13N-5.6P-10.9K (13-13-13) at rates of 4.9 g N/m(2) and 9.8 g N/m(2), Polyon (R) 13N-5.6P-10.9K (13-13-13) at rates of 4.9 g N/m(2) and 9.8 g N/m(2), and CPL at rates of 4.9 g N/m(2), 9.8 g N/m(2), 19.6 g N/m(2), 29.4 g N/m(2), 39.2 g N/m(2), and 49 g N/m(2). Use of CPL incorporated into landscape planting beds as a fertilizer source resulted in plants equal to or larger than plants grown with conventional inorganic fertilizers. Nitrate (NO(3)) and ammonia (NH(4)) levels in leachates from plots amended with CPL were comparable with plots amended with commercial inorganic fertilizers and nitrogen (N) levels were in most cases less in plots fertilized with CPL when compared with inorganic fertilizers when the same N rate was applied. Composted poultry litter may not be able to fully replace inorganic fertilizers, but it can reduce inorganic fertilizer requirements and provide an environmentally sound alternative to poultry waste disposal as well as provide beneficial aspects for plant growth in annual bedding plants.

AB Scope: The biological functions of caffeoylquinic acid (CQA) derivatives from various plant sources have been partially elucidated. The objectives were to isolate and purify diCQAs from Yerba mate tea leaves and assess their anti-inflammatory and anti-cancer capabilities in vitro and explore their mechanism of action.
Methods and results: Methanol extracts of dried mate leaves were resolved by flash chromatography and further purified resulting in two fractions one containing 3,4- and 3,5-diCQAs and the other 4,5-diCQA with NMR-confirmed structures. Both fractions inhibited LPS-induced RAW 264.7 macrophage inflammation by suppressing nitric oxide/inducible nitric oxide and prostaglandin E(2)/cyclooxygenase-2 pathways through inhibiting nucleus translocation of Nuclear factor kappa B subunits, p50 and p65. The diCQA fractions inhibited Human colon cancer cells CRL-2577 (RKO) and HT-29 cell proliferation by inducing apoptosis in a time- and concentration-dependent manner, but did not affect the protein levels of p21, p27, p53, and Bax:Bcl-2 ratio in RKO cells. In HT-29 cells, however, the diCQA fractions increased Bax:Bcl-2 ratio. The diCQA fractions increased the activation of caspase-8 leading to cleavage of caspase-3 in both RKO and HT-29 colon cancer cells.
Conclusion: The results suggest that diCQAs in Yerba mate could be potential anti-cancer agents and could mitigate other diseases also associated with inflammation.

AB Blueberries (BB) have been reported to attenuate atherosclerosis in apoE-deficient (ApoE(-/-)) mice. The aim of this study was to evaluate the effects of BB in reducing pro-inflammatory cytokine production in mouse macrophages. ApoE(-/-) mice were fed AlN-93G diet (CD) or CD formulated to contain 1% freeze-dried BB for 5 wk. TNF-alpha and IL-6 were lower in serum of BB-fed mice and TNF-alpha expression in aorta was down-regulated with BB feeding. Protein level and mRNA expression of TNF-alpha and IL-6 were significantly lower in the peritoneal macrophages from mice fed BB without or with LPS or oxLDL stimulation. RAW264.7 macrophages were treated with polyphenol-enriched extracts made from the sera of rats fed CD (SEC) or CD containing 10% BB (SEB). SEB significantly inhibited LPS-induced mRNA expression and protein levels of TNF-alpha and IL-6. Furthermore, SEB inhibited the phosphorylation of I kappa B, NF-kappa B p65, MAPK p38 and JNK. All of these are important signaling pathways involved in the production of TNF-alpha and IL-6.

AB Reproductive ecology entails relating the physiology and behavior of an organism to its environment and the community in which it lives. Terrestrial predatory Heteroptera (including Anthocoridae, Geocoridae, Miridae, Nabidae, Pentatomidae, Phymatidae, and Reduviidae) display a wide range of reproductive ecologies. But in spite of this variability, a review of the literature reveals certain underlying trends that are useful in understanding how generalist predators function within their environments. First, the reproductive ecology of predatory bugs is inherently coupled to the physiology of the female and her eggs. Second, three population parameters are directly tied to reproduction (maturation rates, realized fecundity, and reproductive diapause) have great bearing on the rate of population increase and reproductive success of a predatory bug, but these three parameters fluctuate widely within and among species. The variables that affect these processes include the physiological status of the mother (mating status, age and size, and nutritional status), the abiotic environment in which she and her eggs live (temperature, photoperiod, water availability), and natural enemies that attack eggs and reproductive females. A final trend observed in the literature involves the hierarchy of events that must occur before a female finds a suitable oviposition site. Females all must locate preferred habitats, plants/substrates, and microsites in which to insert or deposit an egg, but they use a variety of tactics and cues in order to accomplish this, depending on their life history traits. Examining the factors that constrain and promote the reproductive potential of predatory Heteroptera will make biological control programs that center on them more reliable and sustainable.

AB The human dimensions of biotic invasion are generally poorly understood, even among the most familiar invasive species. Kudzu (Pueraria montana (Lour.) Merr.) is a prominent invasive plant and an example of quasi-wild species, which has experienced repeated introduction, cultivation, and escape back to the wild. Here, we review a large body of primary scientific and historic records spanning thousands of years to characterize the complex relationships among kudzu, its natural enemies, and humans, and provide a synthesis and conceptual model relevant to the ecology and management of quasi-wild invasive species. We documented over 350, mostly insect, natural enemy species and their impacts on kudzu in its native East Asian range. These natural enemies play a minor role in limiting kudzu in its native range, rarely generating severe impacts on populations of wild kudzu. We identified a number of significant influences of humans including dispersal, diverse cultural selection, and facilitation through disturbances, which catalyzed the expansion and exuberance of kudzu. On the other hand, harvest by humans appears to be the major control mechanism in its native areas. Humans thus have a complex relationship with kudzu. They have acted as both friend and foe, affecting the distribution and abundance of kudzu in ways that vary across its range and over time. Our conceptual model of kudzu emphasizes the importance of multiple human dimensions in shaping the biogeography of a species and illustrates how kudzu and other quasi-wild species are more likely to be successful invaders.

AB Mechanisms underlying invasive species impacts remain incompletely understood. We tested the hypothesis that priority resource access by an invasive biocontrol weevil, Rhinocyllus conicus, intensifies and alters the outcome of competition with native floral herbivores over flower head resources of the non-target, native host plant Cirsium canescens, specifically with the predominant, synchronous tephritid fly Paracantha culta. Four main results emerged. First, we documented strong, asymmetric competition, with R. conicus out-competing P. culta. Second, weevil priority access to floral resources accelerated competitive suppression of P. culta. Evidence for competitive suppression with increased weevil priority included decreases in both the numbers and the total biomass of native flies, plus decreases in individual P. culta fly mass and, so, potential fitness. Third, we found evidence for three concurrent mechanisms underlying the competitive suppression of P. culta by R. conicus. Prior use of a flower head by R. conicus interfered with P. culta pre-oviposition behavior. Once oviposition occurred, the weevil also reduced fly post-oviposition performance. Preemptive resource exploitation occurred, shown by the significant effect of flower head size on the total number of insects developing and in the magnitude of R. conicus effects on P. culta. Interference also occurred, shown by a spatial shift of surviving P. culta individuals away from the preferred receptacle resources as R. conicus priority increased. Finally, fourth, using an individual-based model (IBM), we found that the competitive interactions documented have the potential for imposing demographic consequences, causing a reduction in P. culta population sizes. Thus, priority resource access by an invasive insect increased competitive impact on the predominant native insect in the invaded floral guild. This study also provides the first experimental evidence for non-target effects of a weed biological control agent on an associated native insect herbivore.

AB The legume Chamaecrista fasciculata attracts ants to its extrafloral nectar (EFN) which can lead to reduced herbivory and increased fecundity for the plant. In Florida, Opuntia stricta and O. humifusa, hosts of the invasive moth Cactoblastis cactorum, are often found growing in close association with C. fasciculata. We tested the hypotheses that O. stricta and O. humifusa individuals have higher ant abundance, lower levels of herbivore damage, and increased growth when growing in close association with C. fasciculata compared with individuals not growing near the plant. We also experimentally placed C. cactorum eggsticks and pupae on Opuntia individuals to see if ant predation of these stages occurred, and if so, whether predation rates were higher on individuals growing close to C. fasciculata. Opuntia plants near C. fasciculata were less likely to be attacked by C. cactorum and had higher ant abundance than plants far from C. fasciculata. Field surveys showed that Opuntia plants near C. fasciculata had a lower proportion of cladodes with C. cactorum damage of any type. Proportions of cladodes with damage from five native herbivores were not significantly different between treatments. In addition, Opuntia individuals growing near C. fasciculata added proportionately more pads during the growing season. We found evidence of ant predation on 15.9% of C. cactorum eggsticks and 17.6% of pupae. In August and October of 2008, there was significantly more evidence of predation on eggs and pupae placed on Opuntia individuals near C. fasciculata. No effect of distance to C. fasciculata was seen in November of 2008, potentially because plants were no longer producing EFN at this time. Our finding that Opuntia plants close to C. fasciculata show reduced herbivory from invasive C. cactorum, but not from the native herbivores examined, suggests that patterns of associational resistance may be influenced by the co-evolutionary history of the organisms in question.

AB Although invasion of exotic ambrosia beetles (fungus feeders) and bark beetles (phloem feeders) (Coleoptera: Curculionidae: Scolytinae) is considered a major threat to forest health worldwide, no studies have quantitatively investigated the anthropogenic and environmental factors shaping the biogeographical patterns of invasion by these insects across large spatial scales. The primary aim of this study was to assess the relative importance of international trade and several environmental variables of the recipient region on species richness of established exotic Scolytinae. As a reference, we also evaluated the relationships between the same environmental variables and species richness of native Scolytinae. Using an information-theoretic framework for model selection and hierarchical partitioning, we evaluated the relative importance of the potential drivers of species richness of native and exotic Scolytinae in 20 European countries and the 48 contiguous continental US states. Analyses were conducted separately for ambrosia and bark beetle species. Value of imports was a strong predictor of the number of exotic Scolytinae species in both regions. In addition, in the USA, warmer and wetter climate was positively linked to increased numbers of both native and exotic ambrosia beetles. Forest heterogeneity and climatic heterogeneity and secondarily forest area were key drivers in explaining patterns of species richness for native bark beetles but not for exotic species in both regions. Our findings suggest that if current infestation levels continue on imported plants and wood packaging material, increasing international trade will likely lead to more establishments of exotic Scolytinae with concomitant negative effects on forest health in both Europe and the USA. Compared to Europe the risk of invasion appears higher in the USA, especially for ambrosia beetles in the southeastern USA where the climate appears highly suitable for exotic establishment.

AB Post-introduction evolution of increased growth or reproduction has been observed in many species of invasive plants; however, it is not consistently associated with a loss of defense, as predicted by the influential evolution of increased competitive ability (EICA) hypothesis. Inconsistent support for the EICA hypothesis likely reflects the fact that, although invasive plants are released from attack by some enemies, typically specialists, they often do not escape attack from generalists. Thus, different types of defense (e.g., structural versus chemical) may evolve in different directions following introduction. We used a common garden experiment to test whether a shift in allocation among defenses (as opposed to a simple increase or decrease in a single defense) is associated with increased growth in introduced Verbascum thapsus populations. Introduced populations had significantly greater shoot biomass than natives. However, root biomass was similar between ranges, and highly variable, resulting in only marginal differences in total biomass. Mean investment in all three defenses was remarkably similar between the native and introduced populations, providing no evidence for range-level, post-introduction evolution of defense. This finding was consistent with the fact that, despite significant population-level variability for all defenses, there was little evidence of trade-offs between growth and defense or among different types of defense. These results suggest that evolution of increased growth in V. thapsus is not fueled by decreased allocation to defense, and that selection on defense may vary more at the population scale than the continental scale.

AB The rising volume of electronic data, the growth in cloud computing and the need for secure and affordable large-scale data storage all contribute to the increasing reliance on data centers in society. This paper provides an overview of security issues relevant to data centers. We offer an aggregation and exploratory analysis of four audit reports of government data centers operating in the United States. Using the information security common body of knowledge to categorize audit findings, we identify the key issues from the reoccurring findings in the reports, particularly in regards to operations security, data center management, physical security, and disaster planning. The security of data centers has become a paramount concern for both government and the information technology industry. Both practitioners and academics can benefit from our research results because it provides insight into the key security issues facing modern data centers. (C) 2011 Elsevier Inc. All rights reserved.

ID SYSTEMATICS; STRAINS; CLADE; DNA
AB The identification and classification of species within the genus Streptomyces is difficult because there are presently 576 species with validly published names and this number increases every year. The value of multilocus sequence analysis applied to the systematics of Streptomyces species has been well demonstrated in several recently published papers. In this study the sequence fragments of four housekeeping genes, atpD, recA, rpoB and trpB, were determined for the type strains of 10 known phytopathogenic species of the genus Streptomyces, including Streptomyces scabiei, Streptomyces acidiscabies, Streptomyces europaeiscabiei, Streptomyces luridiscabiei, Streptomyces niveiscabiei, Streptomyces puniciscabiei, Streptomyces reticuliscabiei, Streptomyces stelliscabiei, Streptomyces turgidiscabies and Streptomyces ipomoeae, as well as six uncharacterized phytopathogenic Streptomyces isolates. The type strains of 52 other species, including 19 species observed to be phylogenetically closely related to these, based on 16S rRNA gene sequence analysis, were also included in the study. Phylogenetic analysis of single gene alignments and a concatenated four-gene alignment demonstrated that the phytopathogenic species are taxonomically distinct from each other in spite of high 16S rRNA gene sequence similarities and provided a tool for the identification of unknown putative phytopathogenic Streptomyces strains at the species level.

PRODUCTION; CHANGE-TYPE DROUGHT; UNITED-STATES; PACIFIC-NORTHWEST;
CLIMATE-CHANGE
AB The United States needs many different types of forests: some managed for wood products plus other benefits, and some managed for nonconsumptive uses and benefits. The objective of reducing global greenhouse gases (GHG) requires increasing carbon storage in pools other than the atmosphere. Growing more forests and keeping forests as forests are only part of the solution, because focusing solely on the sequestration benefits of the forests misses the important (and substantial) carbon storage and substitution GHG benefits of harvested forest products, as well as other benefits of active forest management.
Forests and global climate are closely linked in terms of carbon storage and releases, water fluxes from the soil and into the atmosphere, and solar energy capture. Understanding how carbon dynamics are affected by stand age, density, and management and will evolve with climate change is fundamental to exploiting the capacity for sustainably managed forests to remove carbon dioxide from the atmosphere. For example, even though emperate forests continue to be carbon sinks, in western North America forest fires and tree mortality from insects are converting some forests into net carbon sources.
Expanding forest biomass use for biofuels and energy generation will compete with traditional forest products, but it may also produce benefits through competition and market efficiency. Short-rotation woody crops, as well as landowners' preferences-based on investment-return expectations and environmental considerations, both of which will be affected by energy and environmental policies-have the potential to increase biomass supply.
Unlike metals, concrete, and plastic, forest products store atmospheric carbon and have low embodied energy (the amount of energy it takes to make products), so there is a substitution effect when wood is used in place of other building materials. Wood used for energy production also provides substitution benefits by reducing the flow of fossil fuel based carbon emissions to the atmosphere.
The value of carbon credits generated by forest carbon offset projects differs dramatically, depending on the sets of carbon pods allowed by the protocol and baseline employed. The costs associated with establishing and maintaining offset projects depend largely on the protocols' specific.. Measurement challenges and relatively high transaction costs needed for forest carbon offsets warrant consideration of other policies that promote climate benefits from forests and forest products but do not require project-specific accounting.
Policies can foster changes in forest management and product manufacture that reduce carbon emissions over time while maintaining forests for environmental and societal benefits. US policymakers should take to heart the finding of the Intergovernmental Panel on Climate Change in its Fourth Assessment Report when it concluded that "In the long term, a sustainable forest management strategy aimed at maintaining or increasing forest carbon stocks, while producing on annual sustained yield of timber, fibre, or energy from the forest, will generate the largest sustained mitigation benefit." A rational energy and environmental policy framework must be based on the premise that atmospheric greenhouse gas levels are increasing primarily because of the addition of geologic fossil fuel-based carbon into the carbon cycle. Forest carbon policy that builds on the scientific information summarized in this article can be a significant and important part of a comprehensive energy policy that provides for energy independence and carbon benefits while simultaneously providing clean water, wildlife habitat, recreation, and other uses and values.

AB A 3D log sawing optimization system was developed to perform log generation, opening face determination, sawing simulation, and lumber grading using 3D modeling techniques. Heuristic and dynamic programming algorithms were used to determine opening face and grade sawing optimization. Positions and shapes of internal log defects were predicted using a model developed by the USDA Forest Service. Lumber grading procedures were based on National Hardwood Lumber Association rules. The system was validated through comparisons with sawmill lumber values. External characteristics of logs, including length, large-end and small-end diameters, diameters at each foot, and defects were collected from five local sawmills in central Appalachia. Results indicated that hardwood sawmills have the potential to increase lumber value through optimal opening face and sawing optimizations. With these optimizations, average lumber value recovery could be increased by 10.01% using the heuristic algorithm or 14.21% using the dynamic programming algorithm. Lumber grade was improved significantly by using the optimal algorithms. For example, recovery of select or higher grade lumber increased 16-30%. This optimization system would help small sawmill operators improve their processing performance and improve industry competitiveness.

AB Campylobacter jejuni is one of the most common causes of human bacterial enteritis worldwide. The molecular mechanisms of the host responses of chickens to C. jejuni colonization are not well understood. We have previously found differences in C. jejuni colonization at 7-days post-inoculation (pi) between two genetic broiler lines. However, within each line, not all birds were colonized by C. jejuni (27.5% colonized in line A, and 70% in line B). Therefore, the objective of the present experiments was to further define the differences in host gene expression between colonized and non-colonized chickens within each genetic line. RNA isolated from ceca of colonized and non-colonized birds within each line was applied to a chicken 44K Agilent microarray for the pair comparison. There were differences in the mechanisms of host resistant to C. jejuni colonization between line A and line B. Ten times more differentially expressed genes were observed between colonized and non-colonized chickens within line B than those within line A. Our study supports the fact that the MAPK pathway is important in host response to C. jejuni colonization in line B, but not in line A. The data indicate that inhibition of small GTPase-mediated signal transduction could enhance the resistance of chickens to C. jejuni colonization and that the tumour necrosis factor receptor superfamily genes play important roles in determining C. jejuni non-colonization in broilers.

AB Premise of the study: How a leaf acquires its shape is a major and largely unresolved question in plant biology. This problem is particularly complex in the case of compound leaves, where the leaf blade is subdivided into leaflets. In many eudicots with compound leaves, class I KNOTTED1-LIKE HOMEOBOX (KNOX) genes are upregulated in the leaf primordium and promote leaflet initiation, while KNOX genes are restricted to the shoot apical meristem in simple-leaved plants. In monocots, however, little is known about the extent of KNOX contribution to compound leaf development, and we aimed to address this issue in the palm Chamaedorea elegans.
Methods: We investigated the accumulation pattern of KNOX proteins in shoot apical meristems and leaf primordia of the palm C. elegans using immunolocalization experiments.
Key results: KNOX proteins accumulated in vegetative and inflorescence apical meristems and in the subtending stem tissue, but not in the plicated regions of the leaf primordia. These plicated areas form during primary morphogenesis and are the only meristematic tissue in the developing primordium. In addition, KNOX proteins did not accumulate in any region of the developing leaf during secondary morphogenesis, when leaflets separate to create the final pinnately compound leaf.
Conclusions: The compound leaf character in palms, C. elegans in particular and likely other pinnately compound palms, does not depend on the activities of KNOX proteins.

AB Rocky Mountain spotted fever, Lyme disease, and ehrlichiosis are tick-borne diseases that are reported annually in Kentucky. We conducted a survey to describe infection prevalence of tick-borne pathogens in Amblyomma americanum and Dermacentor variabilis ticks collected in Kentucky. During 2007-2008, we collected 287 ticks (179 D. variabilis and 108 A. americanum) from canine, feral hog, horse, raccoon, white-tailed deer, and human hosts in six counties in Kentucky. Ticks were screened for Rickettsia spp., Borrelia spp., and Ehrlichia spp. by using polymerase chain reaction. Forty-one (14.3%) ticks (31 A. americanum and 10 D. variabilis) were polymerase chain reaction positive for a Rickettsia spp. Fourteen (4.9%) ticks (6 A. americanum and 8 D. variabilis) were positive for E. chaffeensis, and 4 A. americanum (1.4%) were positive for E. ewingii. One (0.4%) A. americanum was positive for Borrelia lonestari. Although Rocky Mountain spotted fever is diagnosed in Kentucky, no R. rickettsii was found in ticks in this study.

AB We report an outbreak of equine piroplasmosis in southern Texas, USA, in 2009. Infection prevalence reached 100% in some areas (292 infected horses). Amblyomma cajennense was the predominant tick and experimentally transmitted Theileria equi to an uninfected horse. We suggest that transmission by this tick species played a role in this outbreak.

AB Biosurfactants are diverse molecules with numerous biological functions and industrial applications. A variety of environments were examined for biosurfactant-producing bacteria including soil, water and leaf surfaces. Biosurfactant production was assessed with an atomized oil assay for a large number of bacterial isolates and compared with a commonly used drop collapse assay from broth and plate cultures. The atomized oil assay detected every strain that produced a biosurfactant detectable by the drop collapse test, and also identified additional strains that were not detected with the drop collapse assay because they produced low levels of surfactant or hydrophobic (low water solubility) surfactants such as pumilacidins. Not all strains that produced a biosurfactant detectable by the drop collapse when cultured on agar surfaces produced surfactants detectable by drop collapse when cultured in broth, and vice versa. Many bacterial strains exhibited preferential production of surfactants when grown on an agar surface compared with broth cultures, and such surface enhancement of production could also be stimulated by increasing the viscosity of liquid culture media. Surface induction of surfactant production in the epiphyte Pseudomonas syringae was regulated at the transcriptional level.

AB We review the ecological consequences of N deposition on the five Mediterranean regions of the world. Seasonality of precipitation and fires regulate the N cycle in these water-limited ecosystems, where dry N deposition dominates. Nitrogen accumulation in soils and on plant surfaces results in peaks of availability with the first winter rains. Decoupling between N flushes and plant demand promotes losses via leaching and gas emissions. Differences in P availability may control the response to N inputs and susceptibility to exotic plant invasion. Invasive grasses accumulate as fuel during the dry season, altering fire regimes. California and the Mediterranean Basin are the most threatened by N deposition; however, there is limited evidence for N deposition impacts outside of California. Consequently, more research is needed to determine critical loads for each region and vegetation type based on the most sensitive elements, such as changes in lichen species composition and N cycling.

AB We reviewed the published evidence of lead (Pb) contamination of urban soils, soil Pb risk to children through hand-to-mouth activity, reduction of soil Pb bioavailability due to soil amendments, and methods to assess bioaccessibility which correlate with bioavailability of soil Pb. Feeding tests have shown that urban soils may have much lower Pb bioavailability than previously assumed. Hence bioavailability of soil Pb is the important measure for protection of public health, not total soil Pb. Chemical extraction tests (Pb bioaccessibility) have been developed which are well correlated with the results of bioavailability tests; application of these tests can save money and time compared with feeding tests. Recent findings have revealed that fractional bioaccessibility (bioaccessible compared to total) of Pb in urban soils is only 5-10% of total soil Pb, far lower than the 60% as bioavailable as food-Pb presumed by U.S.-EPA (30% absolute bioavailability used in IEUBK model).

AB Mechanical ventilation (MV) can induce lung oxidative stress, which plays an important role in pulmonary injury. This study compared protective conventional mechanical ventilation (CMV) and high-frequency oscillatory ventilation (HFOV) for oxygenation, oxidative stress, inflammatory and histopathological lung injury in a rabbit model of acute lung injury (ALI). Rabbits (n = 30) were ventilated at FiO(2) 1.0. Lung injury was induced by tracheal saline infusion (30 mL/kg, 38 degrees C). Animals were randomly assigned to: (a) sham control (CG: tidal volume [V(T)] 6 mL/kg, positive end expiratory pressure [PEEP] 5 cmH(2)O, respiratory rate [RR] 40 ipm); (b) ALI + CMV (CMVG: V(T) 6 mL/kg, PEEP 10 cmH(2)O, RR 40 ipm); or (c) ALI + HFOV (HFG: mean airway pressure [Paw] 14 cmH(2)O, RR 10 Hz) groups. Lung oxidative stress was assessed by total antioxidant performance assay, inflammatory response by the number of polymorphonuclear leukocytes/bronchoalveolar lavage fluid/lung and pulmonary histological damage was quantified by a score. Ventilatory and hemodynamic parameters were recorded every 30 min. Both ALI groups showed worse oxygenation after lung injury induction. After four hours of ventilation, HFG showed better oxygenation (partial pressure of oxygen [PaO(2)] - CG: 465.9 +/- 30.5 = HFG: 399.1 +/- 98.2 > CMVG: 232.7 +/- 104 mmHg, P < 0.05) and inflammatory responses (CMVG: 4.27 +/- 1.50 > HFG: 0.33 +/- 0.20 = CG: 0.16 +/- 0.15; polymorphonuclear cells/bronchoalveolar lavage fluid/lung, P < 0.05), less histopathological injury score (CMVG: 5 [1-16] > HFG: 1 [0-5] > CG: 0 [0-3]; P < 0.05), and lower lung oxidative stress than CMVG (CG: 59.4 +/- 4.52 = HFG: 69.0 +/- 4.99 > CMVG: 47.6 +/- 2.58% protection/g protein, P < 0.05). This study showed that HFOV had an important protective role in ALI. It improved oxygenation, reduced inflammatory process and histopathological damage, and attenuated oxidative lung injury compared with protective CMV under these experimental conditions considering the study limitations.

AB In this study, physical, mechanical, and flammability properties of coconut fiber reinforced polypropylene (PP) composite panels were evaluated. Four levels of the coir fiber content (40, 50, 60, and 70 % based on the composition by weight) were mixed with the PP powder and a coupling agent, 3 wt % maleic anhydride grafted PP (MAPP) powder. The water resistance and the internal bond strength of the composites were negatively influenced by increasing coir fiber content. However, the flexural strength, the tensile strength, and the hardness of the composites improved with increasing the coir fiber content up to 60 wt %. The flame retardancy of the composites improved with increasing coir fiber content. The results suggest that an optimal composite panel formulation for automotive interior applications is a mixture of 60 wt % coir fiber, 37 wt % PP powder, and 3 wt % MAPP.

AB There is expanding interest in management strategies that maximize forest carbon (C) storage to mitigate increased atmospheric carbon dioxide. The tremendous tree species diversity and range of stand stocking found across the eastern United States presents a challenge for determining optimal combinations for the maximization of standing tree C storage. Using a nationwide annual forest inventory, we quantified trends in standing tree C across a variety of species mixtures and stocking attributes for 24 of the most common tree species in the eastern United States. We found that as interspecific stocking decreased, such that the majority of stand stocking was in a single species, maximum live tree aboveground carbon (AGC) decreased by 33% in highly stocked stands across all study species. Maximum standing dead tree AGC was not correlated with stand stocking but instead was related to interspecific stocking with AGC storage being reduced by more than 50% as stands became progressively occupied by one tree species. Although the competitive interactions between individual species and/or functional groups (i.e., shade tolerance) can greatly complicate efforts to assess forest C storage opportunities, some basic tenets identified in this study may refine future research hypotheses and broadly identify species mixtures and associated stocking levels that may maximize AGC storage.

AB Substantial investment has been made in the development and application of scientifically based best management practices (i.e., guidelines) intended to protect and enhance the ecological, environmental, and aesthetic attributes of forest resources. When correctly applied, guidelines can increase environmental benefits on site and to adjacent resources, as well as improve forest health and productivity. We empirically evaluated how varying degrees of application of Minnesota's Timber Harvesting and Forest Management guidelines, along with operator and tract-specific variables, affect felling and skidding productivity of mixed aspen/hardwood/conifer stands in northern Minnesota. To do so, felling and skidding productivity data from five mechanized logging businesses were collected on 52 clearcut harvest blocks in northern Minnesota from August 2006 to May 2007 using time-motion and geospatial sensors. Additional postharvest data were collected for each block using high-resolution aerial photography and detailed on-site inventories. With use of these data, separate regression models were developed to estimate the impact that timber harvesting guidelines and tract and operator variables have on felling and skidding productivity. Results of regression analyses and diagnostic tests showed that felling productivity is influenced not only by guideline variables but also by tract and operator variables. Skidding productivity is influenced by both guideline and tract variables. The error terms of the separate felling and skidding models are statistically correlated, calling for their simultaneous estimation using a method known as seemingly unrelated regression. Specific explanatory variables that are statistically significant in explaining felling productivity include the logger's use of a preharvest site map and/or preharvest meeting with the forester, harvesting in winter, merchantable timber volume per unit area, and the operator. Variables that are statistically significant in explaining skidding productivity are the area of landings and skid trails as a percentage of the harvest area, ratio of the harvest block perimeter to the block area, slope, and merchantable timber volume per unit area. The findings suggest that implementing the guidelines we studied has minimal effect on felling productivity, although several adversely affect skidding productivity. By considering how to lay out the harvest block to facilitate skidding efficiency, a feller operator may be able to reduce the impact of some guidelines on skidding productivity. FOR.

TI Toward Efficient Management of Large Fires: A Mixed Integer Programming
Model and Two Iterative Approaches

AB In this study, we developed an optimization model and two iterative approaches to improve the efficiency of large fire management. This model allocates suppression effort across time and space to minimize fire loss within a defined duration. It departs from previous research by replacing simplified fire containment rules with progress-based fire loss control. This is accomplished by extending the minimum travel time algorithm to build a large fire suppression model. Mixed integer programming is used to integrate spatial information such as fire behavior, firefighter safety, and values at risk to guide large fire suppression. The concern of time-specific suppression allocation is modeled through two iterative approaches using different logical procedures. Test cases demonstrate how this model assembles spatial data to support suppression decisions for one fire or multiple simultaneous fires. Suppression is also scheduled across 30 randomly simulated fires in Sequoia and Kings Canyon National Parks. Results demonstrate that suppression delay can significantly increase fire loss. Simulation results show that iterative approach A is more efficient in distributing suppression effort into short time periods. FOR. SCI. 57(5):435-447.

AB An experiment was conducted to test the hypothesis that either pumice or plant roots maintain air space (AS) and porosity over time, or renders substrates more resistant to shrinkage. Treatment design was a 3 x 2 factorial with three substrate types and either presence or absence of a plant. The three substrates were composed of douglas fir (Pseudotsuga menziesii) bark alone or amended with 15% or 30% (by volume) pumice. Substrates were packed in aluminum cores to facilitate measurement of physical properties with porometers at the conclusion of the experiment. Half of the cores with each of the three substrate types were packed with a single plug of 'Autumn Blush' coreopsis (Coreopsis sp.) (Expt. 1) or 'Blue Prince' holly (Ilex xmeserveae) (Expt. 2). The remaining cores were maintained in the same production environment, but without a plant. Substrate physical properties were measured before the experiment and after 48 days for coreopsis plants and 382 days for holly. Both experiments had relatively similar responses despite using different crops and production times. Summarizing in general overall treatments, AS decreased, container capacity (CC) and total porosity (TP) increased, and bulk density remained constant over time. The presence of a plant in the core tended to exacerbate the decrease in AS and the increase in core capacity. Shrinkage was decreased by the presence of a plant, but only minimally.

AB The objective of this study was to evaluate primocane cane training and propagation techniques for the production of long-cane blackberry (Rubus spp.) plants. Seventeen to 29 6-ft-long canes were produced from each semierect 'Triple Crown' and trailing 'Siskiyou' blackberry plant grown on the rotating cross-arm (RCA) trellis and cane training system. By early August, the lateral canes had grown beyond the top wire approximate to 6 ft above the ground and continued growing downward to the ground. The tips of the lateral canes reached the soil level from mid-August to mid-September at which time they were placed in 1/2-gal pots containing peat-based media. In early Oct. 2009, the tip-rooted lateral canes were cut from the stock plant at the uppermost trellis wire. Among the long-cane plants produced in 2009, 76% of buds in 'Siskiyou' broke, but less than 30% of buds in 'Triple Crown' broke in a heated greenhouse. Flowering occurred in 15% of the shoots that developed on rooted 'Siskiyou' long canes, but the shoots on the long-cane plants of 'Triple Crown' were morphologically vegetative and flowering did not occur. In 2010-11, the long-cane plants were detached from the stock plants in December, January, and March. The numbers of nodes with a flowering shoot improved to 41% and 16% and the number of flowers per shoot increased to two and five flowers on long-cane plants of 'Siskiyou' and 'Triple Crown' blackberry, respectively.

AB Greenhouses that are well sealed can result in carbon dioxide (CO2) drawdown and suppressed plant growth. While growers can add supplemental CO2 it is unknown how supplemental CO2 fits within the framework of sustainable crop production in greenhouses. In this study, supplemental CO2 was used in combination with reduced temperatures to evaluate the productivity of 'Grand Rapids' lettuce (Latuca sativa) compared with a traditionally maintained, warmer, and well-insulated greenhouse without supplemental CO2 at a commercial facility. Simulations using Virtual Grower software based on identical greenhouses compared fuel use and carbon (C) consumed because of heating and CO2 supplementation. Models were verified with measurements in a well-sealed commercial greenhouse; CO2 quickly decreased to below 300 ppm in a nonsupplemented greenhouse containing plants. Supplemental CO2 boosted total leaf number and mass of lettuce even though temperatures were maintained 3 degrees F lower in elevated CO2 than in the traditional management scenario. Maintaining a cooler greenhouse but adding CO2 decreased total carbon (C) consumed (by combined fuel use and CO2 supplementation) by 7% during the 3-month season that required a well-sealed greenhouse. Additionally, fuel savings because of lower temperature set points paid for the cost of adding CO2. The use of CO2 enrichment should be considered as a tool in sustainable systems when its use can counteract the plant growth and development reductions brought on by lowered temperatures.

AB Phosphine fumigations under superatmospheric oxygen levels (oxygenated phosphine fumigations) were significantly more effective than the fumigations under the normal 20.9% atmospheric oxygen level against western flower thrips [Frankliniella occidentalis (Pergande)] adults and larvae, leafminer Liriomyza langei Frick pupae, grape mealybug [Pseudococcus maritimus (Ehrhorn)] eggs, and Indianmeal moth [Plodia interpunctella (Hubner)] eggs and pupae. In 5-h fumigations with 1,000 ppm phosphine at 5 degrees C, mortalities of western flower thrips increased significantly from 79.5 to 97.7% when oxygen was increased from 20.9 to 40% and reached 99.3% under 80% O(2). Survivorships of leafminer pupae decreased significantly from 71.2% under 20.9% O(2) to 16.2% under 40% O(2) and reached 1.1% under 80% O(2) in 24-h fumigations with 500 ppm phosphine at 5 degrees C. Complete control of leafminer pupae was achieved in 24-h fumigations with 1,000 ppm phosphine at 5 degrees C under 60% O(2) or higher. Survivorships of grape mealybug eggs also decreased significantly in 48-h fumigations with 1,000 ppm phosphine at 2 degrees C under 60% O(2) compared with the fumigations under 20.9% O(2). Indianmeal moth egg survivorships decreased significantly from 17.4 to 0.5% in responses to an oxygen level increase from 20.9 to 40% in 48-h fumigations with 1,000 ppm phosphine at 10 degrees C and reached 0.2% in fumigations under 80% O(2). Whenthe oxygen level was reduced from 20.9 to 15 and 10% in fumigations, survivorships of Indianmeal moth eggs increased significantly from 17.4 to 32.9 and 39.9%, respectively. Increased O(2) levels also resulted in significantly lower survival rates of Indianmeal moth pupae in response to 24-h fumigations with 500 and 1,000 ppm phosphine at 10 degrees C and a complete control was achieved in the 1,000 ppm phosphine fumigations under 60% O(2). Oxygenated phosphine fumigations have marked potential to improve insecticidal efficacy. Advantages and limitations of oxygenated phosphine fumigation are discussed.

AB Successful transmission of plant pathogens by insects depends on the vector inoculation efficiency and how rapidly the insect can effectively transmit the pathogen to the host plant. The potato psyllid, Bactericera cockerelli (Sulc), has recently been found to transmit "Candidatus Liberibacter solanacearum," a bacterium associated with zebra chip (ZC), an emerging and economically important disease of potato in several parts of the world. Currently, little is known about the epidemiology of ZC and its vector's inoculation capabilities. Studies were conducted in the field and laboratory to 1) assess transmission efficiency of potato psyllid nymphs and adults; 2) determine whether psyllid inoculation access period affects ZC incidence, severity, and potato yield; and 3) determine how fast the psyllid can transmit liberibacter to potato, leading to ZC development. Results showed that adult potato psyllids were highly efficient vectors of liberibacter that causes ZC and that nymphs were less efficient than adults at transmitting this bacterium. It was also determined that inoculation access period had little influence on overall ZC disease incidence, severity, and resulting yield loss. Moreover, results showed that exposure of a plant to 20 adult potato psyllids for a period as short as 1 h resulted in ZC symptom development. Furthermore, it was shown that a single adult potato psyllid was capable of inoculating liberibacter to potato within a period as short as 6 h, thereby inducing development of ZC. This information will help in developing effective management strategies for this serious potato disease.

AB Bactrocera latifrons (Hendel) (Diptera: Tephritidae) is a quarantine pest of several solanaceous crops and tropical fruits that are treated using irradiation before export from Hawaii to the U. S. mainland. A dose of 150 Gy is approved as a generic irradiation treatment for tephritid fruit flies, but no confirmation of efficacy has been reported for B. latifrons. Dose response of B. latifrons was used to determine the most tolerant life stage and identify a dose that prevents adult emergence. Data indicated doses (plus 95% confidence limits) required to prevent adult emergence of 13.4 (10.0-29.6), 17.5 (14.4-24.8), and 88.1 (68.0-133.8) Gy for eggs, first instars and third instars, respectively. In large-scale confirmatory tests of the most radiotolerant life stage, a radiation dose of 150 Gy applied to B. latifrons late third instars in bell peppers (Capsicum annuum L.) resulted in no survival to the adult stage of 157,112 individuals, a treatment efficacy consistent with Probit 9-level mortality. The relative radiotolerance of melon fly Bactrocera cucurbitae Coquillet, and B. latifrons also was tested using a diagnostic radiation dose of 30 Gy. In diet, a mean of 6.9% of irradiated B. cucurbitae third instars developed to the adult stage, whereas no B. latifrons third instars developed to adults. In papaya, Carica papaya L., fruit, a mean of 3.3% of irradiated B. cucurbitae third instars developed to the adult stage, whereas 0.5% B. latifrons third instars developed to adults. This report supports the use of a generic radiation dose of 150 Gy in quarantine scenarios to control tephritid fruit flies on fresh commodities.

AB To help assess the potential for damage by armyworms [Mythimna (Pseudaletia) unipuncta (Haworth) (Lepidoptera: Noctuidae)] to switchgrass (Panicum virgatum L.) and surrounding crops, survival and development were evaluated for larvae reared on leaves of switchgrass, corn (Zea mays L.), and miscanthus (Miscanthus X giganteus Greef and Deuter ex Hodkinson and Renvoize). Additional tests assessed the relationship between leaf position and the concentration of saponins (plant compounds which can provide protection from insect herbivores) and examined the effect of defoliation on switchgrass dry mass. Survival to adulthood was similar when larvae were reared on field-grown leaves of switchgrass and corn. However, lower larval mass (10 d) and delayed development of M. unipuncta (to pupation, adult emergence) suggest switchgrass is an inferior host relative to corn. When fed field-grown miscanthus, no larvae survived 10 d. Few differences were noted between switchgrass and corn grown under controlled (laboratory) conditions, but M. unipuncta survival seemed to decline rapidly when larvae were fed the fourth and fifth leaves of switchgrass. Switchgrass leaf samples collected from different leaf positions and stages of tiller maturity showed up to 10-fold differences in the concentration of the saponin protodioscin, with the greatest concentrations in the fourth and fifth leaves. However, other saponins showed an opposite pattern, indicating the role of protodioscin on insect development should be tested in isolation (e. g., by addition of the purified compound to an artificial diet). Defoliation trials indicated that extremely high M. unipuncta populations may be necessary to cause any significant reduction in switchgrass biomass. Collectively, results suggest M. unipuncta may not present a significant risk to biomass production in switchgrass, but that the spring emergence of switchgrass provides an alternate host for M. unipuncta before colonizing annual food and feed crops.

TI Impact of Lygus spp. (Hemiptera: Miridae) on Damage, Yield and Quality

AB Lesquerella, Physaria fendleri (A. Gray) S. Watson, is a mustard native to the western United States and is currently being developed as a commercial source of valuable hydroxy fatty acids that can be used in a number of industrial applications, including biolubricants, biofuel additives, motor oils, resins, waxes, nylons, plastics, corrosion inhibitors, cosmetics, and coatings. The plant is cultivated as a winter-spring annual and in the desert southwest it harbors large populations of arthropods, several of which could be significant pests once production expands. Lygus spp. (Hemiptera: Miridae) are common in lesquerella and are known pests of a number of agronomic and horticultural crops where they feed primarily on reproductive tissues. A 4-yr replicated plot study was undertaken to evaluate the probable impact of Lygus spp. on production of this potential new crop. Plant damage and subsequent seed yield and quality were examined relative to variable and representative densities of Lygus spp. (0.3-4.9 insects per sweep net) resulting from variable frequency and timing of insecticide applications. Increasing damage to various fruiting structures (flowers [0.9-13.9%], buds [1.2-7.1%], and seed pods [19.4-42.5%]) was significantly associated with increasing pest abundance, particularly the abundance of nymphs, in all years. This damage, however, did not consistently translate into reductions in seed yield (481-1,336 kg/ha), individual seed weight (0.5-0.7 g per 1,000 seed), or seed oil content (21.8-30.4%), and pest abundance generally explained relatively little of the variation in crop yield and quality. Negative effects on yield were not sensitive to the timing of pest damage (early versus late season) but were more pronounced during years when potential yields were lower due to weed competition and other agronomic factors. Results suggest that if the crop is established and managed in a more optimal fashion, Lygus spp. may not significantly limit yield. Nonetheless, additional work will be needed once more uniform cultivars become available and yield effects can be more precisely measured. Densities of Lygus spp. in unsprayed lesquerella are on par with those in other known agroecosystem level sources of this pest (e. g., forage and seed alfalfa, Medicago sativa L.). Thus, lesquerella production may introduce new challenges to pest management in crops such as cotton.

AB Mortality of the western corn rootworm, Diabrotica virgifera virgifera LeConte, larvae due to feeding on maize, Zea mays L., expressing Bacillus thuringiensis Berliner (Bt) was evaluated in five Missouri sites in 2007, 2008, and 2009. Specifically, eCry3.1Ab (5307), mCry3A (MIR604), and eCry3.1Ab plus mCry3A proteins relative to survivorship on maize with the same genetic background without these genes (isoline maize) was evaluated. An average of 890.8 +/- 152.3 beetles emerged from isoline plots, whereas average beetle emergence from 5307, MIR604, and 5307 X MIR604 was 1.9 +/- 0.6, 19.3 +/- 6.3, and 0.8 +/- 0.3, respectively, when averaged across 22 replications in five environments. Overall, 66, 50, 61, and 51% of beetles recovered from 5307, MIR604, 5307 X MIR604, and isoline maize, respectively, were female, and there was no significant difference between the number of male and female beetles that emerged from any of these treatments. Mortality due to 5307, MIR604, and 5307 X MIR604 was 99.79, 97.83, and 99.91%, respectively. There was an 8.0-d delay in time to 50% beetle emergence from 5307 compared with isoline maize, which was significantly later than to the other three maize lines. The average delay to 50% emergence from MIR604 and 5307 X MIR604 averaged 4.1 and 4.6 d, respectively later than 50% emergence from isoline maize. Female beetles had a significant delay in time to 50% emergence compared with male beetles from all treatments with the exception of 5307 X MIR604. Data are discussed in terms of insect resistance management in relation to other control measures for western corn rootworm.

AB Effective methods are needed to protect ash trees (Fraxinus spp.) from emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive buprestid that has killed millions of North American ash (Fraxinus spp.) trees. We randomly assigned 175 ash trees (11.5-48.1 cm in diameter) in 25 blocks located in three study sites in Michigan to one of seven insecticide treatments in May 2007. Treatments included 1) trunk-injected emamectin benzoate; 2) trunk-injected imidacloprid; 3) basal trunk spray of dinotefuran with or 4) without Pentra-Bark, an agricultural surfactant; 5) basal trunk spray of imidacloprid with or 6) without Pentra-Bark; or (7) control. Foliar insecticide residues (enzyme-linked immunosorbent assay) and toxicity of leaves to adult A. planipennis (4-d bioassays) were quantified at 3-4-wk intervals posttreatment. Seven blocks of trees were felled and sampled in fall 2007 to quantify A. planipennis larval density. Half of the remaining blocks were retreated in spring 2008. Bioassays and residue analyses were repeated in summer 2008, and then all trees were sampled to assess larval density in winter. Foliage from emamectin benzoate-treated trees was highly toxic to adult A. planipennis, and larval density was <1% of that in comparable control trees, even two seasons posttreatment. Larval densities in trees treated with trunk-injected imidacloprid in 2007 + 2008 were similar to control trees. Dinotefuran and imidacloprid were effectively translocated within trees treated with the noninvasive basal trunk sprays; the surfactant did not appreciably enhance A. planipennis control. In 2008, larval densities were 57-68% lower in trees treated with dinotefuran or imidacloprid trunk sprays in 2007 + 2008 than on controls, but densities in trees treated only in 2007 were similar to controls. Highly effective control provided by emamectin benzoate for >= 2 yr may reduce costs or logistical issues associated with treatment.

AB The plum curculio, Conotrachelus nenuphar (Herbst), is a key pest of pome and stone fruit in eastern and central North America. For effective management of this insect pest in commercial apple (Malus spp.) orchards in the northeastern United States and Canada, one of the greatest challenges has been to determine the need for and timing of insecticide applications that will protect apple fruit from injury by adults. In a 2004-2005 study, we assessed the efficacy and economic viability of a reduced-risk integrated pest management strategy involving an odor-baited trap tree approach to determine need for and timing of insecticide use against plum curculio based on appearance of fresh egg-laying scars. Evaluations took place in commercial apple orchards in seven northeastern U. S. states. More specifically, we compared the trap-tree approach with three calendar-driven whole-block sprays and with heat-unit accumulation models that predict how long insecticide should be applied to orchard trees to prevent injury by plum curculio late in the season. Trap tree plots received a whole-plot insecticide spray by the time of petal fall, and succeeding sprays (if needed) were applied to peripheral-row trees only, depending on a threshold of one fresh plum curculio egg-laying scar out of 25 fruit sampled from a single trap tree. In both years, level of plum curculio injury to fruit sampled from perimeter-row, the most interior-row trees and whole-plot injury in trap tree plots did not differ significantly from that recorded in plots subject to conventional management or in plots managed using the heat-unit accumulation approach. The amount of insecticide used in trap tree plots was reduced at least by 43% compared with plots managed with the conventional approach. Advantages and potential pitfalls of the bio-based trap tree approach to plum curculio monitoring in apple orchards are discussed.

AB Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) pose a significant challenge to producers of ornamental nursery stock. Conventional insecticides are commonly used for management purposes, but plant-derived essential oils also may discourage ambrosia beetles from initiating attacks. To identify promising commercially available products, field-based efficacy trials were conducted in Ohio in 2009 and 2010 with the following products: Armorex (Soil Technologies), Cinnacure (Proguard, Inc.), EcoTrol (EcoSMART Technologies, Inc.), and Veggie Pharm (Pharm Solutions, Inc.). Potted Magnolia virginiana L. were first injected with 75 ml of 5% ethanol to ensure ambrosia beetle pressure on experimental trees. Mixtures of each product (10% in water) and a water control were applied until runoff and attacks occurring under field conditions were quantified at 1, 4, 7, and 14 d after treatment (DAT). Ambrosia beetle attacks generally increased over time but at differing rates depending on the particular treatment. In 2009, Armorex and Veggie Pharm were associated with the lowest cumulative attacks 14 DAT. In 2010, Armorex and Cinnacure were associated with the fewest attacks 14 DAT. Solid phase microextraction-gas chromatography-mass spectrometry was used to characterize the volatile compounds associated with each product. Allyl isothiocyanate, a compound with known repellent and insecticidal properties, was unique and predominant in Armorex. These experiments identified commercially available botanicals containing plant essential oils with activity against ambrosia beetles, along with demonstrating the usefulness of ethanol-injection to ensure ambrosia beetle pressure under field conditions. Characterizing the constituents of efficacious botanically based products could also lead to the development of improved botanical insecticides.

AB A molecular assay for diagnosis of light brown apple moth, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), in North America is reported. The assay multiplexes two TaqMan real-time polymerase chain reaction (RT-PCR) probe systems that are designed to target DNA segments of the internal transcribed spacer region 2 (ITS2) and 18S rRNA gene. The RT-PCR probe designed for the 18S target recognizes a DNA sequence conserved in all of the moths included in the study and functions as a control in the assay. The second probe recognizes a segment of the ITS2 specifically found in E. postvittana and not found in the other moths included in the study, i.e., this segment is not conserved. Inclusion of the two markers in a single multiplex reaction did not affect assay performance. The assay was tested against 637 moths representing >90 taxa in 15 tribes in all three subfamilies in the Tortricidae. The assay generated no false negatives based on analysis of 355 E. postvittana collected from California, Hawaii, England, New Zealand, and Australia. Analysis of a data set including 282 moths representing 41 genera generated no false positives. Only three inconclusive results were generated from the 637 samples. Spike experiments demonstrated that DNA contamination in the assay can affect samples differently. Contaminated samples analyzed with the ITS2 RT-PCR assay and DNA barcode methodology by using the cytochrome oxidase I gene can generate contradictory diagnoses.

Exposure to pyriproxyfen significantly reduced the numbers of both adults and nymphs in comparison with untreated controls. In adults, the greatest reduction (>90%) was for L. decolor and L. bostrychophila, whereas for L. paeta it was 49%. Few adults of any species were found in the pyriproxyfen treatments. The greatest numbers of nymphs were recorded for L. bostrychophila for both pyriproxyfen treatments and controls. Few adults of any species were found in the pyriproxyfen treatments. The results indicate that pyriproxyfen is effective for control of L. bostrychophila, L. decolor, and L. paeta on concrete, and although complete control was not achieved, the results warrant further long-term study to determine whether pyriproxyfen can completely eliminate psocid populations over time.

AB Pheromone trap captures of Helicoverpa zea (Boddie) and Heliothis virescens (F.) from 2002 - 2005 were used to examine the distribution of these species across a multiple crop environment in southeast Arkansas. The greatest number of H. virescens moths was collected during 2003, but densities were low compared with H. zea throughout the study. Overall, fewer H. virescens moths were captured next to Bt corn and Bt cotton than next to nonBt cotton and early-maturing soybean. A significant relationship was not detected between pheromone trap captures of H. virescens and the percentage of these moths that fed on cotton as larvae. More H. zea moths were captured in traps located next to Bt corn and nonBt corn during the month of June than in traps located next to cotton, sorghum, or soybean, whereas traps located adjacent to early- and late-maturing varieties of soybean, Bt cotton, nonBt cotton, and grain sorghum captured greater numbers of moths than those traps located next to corn during July. Therefore, the distribution of H. zea appeared to be influenced by corn acreage during the month of June. Later in the season, this species was widely distributed across the agricultural landscape. Compared with 2 other regions of AR, fewer H. zea moths were captured during the month of June and more H. virescens moths were captured during August in Mississippi Co., an area of intense cotton production.

AB Reticulitermes flavipes (Kollar), R. virginicus Banks, and Coptotermes formosanus Shiraki were stressed by holding them at 25 degrees C or 28 degrees C, respectively, in metal pans for 5 d prior to introduction into 1 side of 3-jar arenas (3 containers connected serially) containing freshly-collected nestmates. After 14 d, mass loss of wooden blocks was determined for blocks from the arena side to which stressed termites were added (treated) as well as those from the opposite side (control). Feeding effects of termite exposure to stress were inconsistent among species. For R. flavipes, there was no significant difference in feeding; whereas loss of block mass on the treated side in R. virginicus arenas was significantly greater (P = 0.0017) than that on the control side of the arenas. For C. formosanus, mass loss of wafers also was significantly greater (P = 0.0284) on the treated side of the arenas, similar to the response of R. virginicus.

AB Ground-surface arthropods were captured by barrier pitfall traps over a 15-month period in an old-field habitat adjacent to a cotton field. Members of the Coleoptera, Orthoptera, and Araneae constituted 89% of the 11,496 captures. The most abundant species group was Gryllus sp. (Orthoptera: Gryllidae). The most abundant predator species was Megacephala caroline L. (Coleoptera: Cicindelidae), present in atypically large numbers. The peak abundance of nymphal Gtyllus sp. (July-October) overlapped the peak abundance period (August) of M. carolina. Feeding experiments indicated M.carolina adults were active predators on Gryllus sp. nymphs. As a potential biocontrol agent, methods to encourage M. carolina adults to move each season from old-field habitats into adjacent crop fields should be considered.

Cotton
SO JOURNAL OF ENTOMOLOGICAL SCIENCE

DT Article
DE defoliants; whitefly; parasitoids; insecticide
AB Cotton defoliation is an important management practice associated with high-yielding, high-quality cotton. The impacts of two commonly-used defoliants (tribufos and thidiazuron) individually and in combination with two commonly-used insecticides (lambda-cyhalothrin and azinphosmethyl) on the sweetpotato whitefly, Bemisia tabaci Gennadius biotype B (= silverleaf whitefly, Bemisia argentifolii Bellows & Perring) and its parasitoids were determined in field studies in the Lower Rio Grande Valley of Texas. The two defoliants and their combinations with azinphosmethyl and lambda-cyhalothrin significantly affected the occurrence and survival of sweetpotato whiteflies and their parasitoids, Encarsia spp. and Eretmocerus spp., although the effects varied among the treatment combinations. Lambda-cyhalothrin alone had no significant effects on sweetpotato whitefly and its parasitoids. Combining defoliants and insecticides appears to be a potential management tool for whiteflies on cotton.

AB Cattle fed finishing diets with wet distillers grains with solubles (WDGS) have been shown to harbor increased Escherichia coli O157:H7 populations in the feces and on the hides. To determine if feeding a lower level of WDGS at the end of the feeding period reduces E. coli O157:H7 load at harvest, 608 heifers were sorted into one of five treatments and fed 0, 40, or 70% WDGS (dry matter basis). For three of the treatments, WDGS was reduced midway through the study. Treatment 0W0W heifers (positive control) were fed a corn grain based diet continuously, and 40W40W heifers (negative control) were fed 40% WDGS continuously. Heifers subjected to treatments 40W0W, 40W15W, and 70W15W were fed either 40 or 70% WDGS for the first 56 days and switched to 0 or 15% WDGS, respectively, for the last 56 days. Prior to the switch in diets, animals fed diets with 40 or 70% had higher prevalence and percent enumerable fecal samples for E. coli O157:H7. After the dietary switch, animals fed 40W0W, 40W15W, and 70W15W diets had fecal prevalence and percent enumerable samples (33.4 and 6.3%, 31.0 and 9.7%, and 34.9 and 8.4%, respectively) similar to those of animals fed 0W0W diets (10.2 and 3.2%, respectively; P > 0.05), whereas animals fed 40W40W had the highest fecal prevalence and percent enumerable samples (70.1 and 29.2%, respectively; P < 0.05). Similar relationships between the treatments were observed for hide samples. Time after dietary switch was important, as animals fed lower levels had significantly lower fecal prevalence and percent enumerable samples after 56 days, but not after 28 days. The study indicates that cattle can be switched to lower levels of dietary WDGS (15% or less) 56 days prior to harvest to significantly reduce E. coli O157:H7 in feces and on hides.

AB Validation of model predictions for independent variables not included during model development can save time and money by identifying conditions for which new models are not needed. A single strain of Salmonella Typhimurium DT104 was used to develop a general regression neural network (GRNN) model for growth of a low inoculum size (0.9 log) on chicken skin with native microflora as a function of time (0 to 8 h) and temperature (20 to 45 degrees C). The ability of the GRNN model to predict growth of higher inoculum sizes (2, 3, or 4.1 log) was evaluated. When the proportion of residuals in an acceptable prediction zone (pAPZ) from -1 log (fail-safe) to 0.5 log (fail-dangerous) was >= 0.7, the GRNN model was classified as providing acceptable predictions of the test data. The pAPZ for dependent data was 0.93 and for independent data for interpolation was 0.88. The pAPZs for extrapolation to higher inoculum sizes of 2, 3, or 4.1 log were 0.92, 0.73, and 0.77, respectively. However, residual plots indicated local prediction problems with pAPZs of <0.7 for an inoculum size of 3 log at 30, 35, and 40 degrees C and for an inoculum size of 4.1 log at 35 and 40 degrees C where predictions were fail-dangerous, indicating faster growth at higher inoculum sizes. The model provided valid predictions of Salmonella Typhimurium DT104 growth on chicken skin from inoculum sizes of 0.9 and 2 log at all temperatures investigated and from inoculum sizes of 3 and 4.1 log at some but not all temperatures investigated. Thus, the model can be improved by including inoculum size as an independent variable.

AB Salmonella enterica is one of the most common bacterial pathogens implicated in foodbome outbreaks involving fresh produce in the last decade. In an effort to discover natural antimicrobials for use on fresh produce, the objective of the present study was to evaluate the effectiveness of different antimicrobial plant extract concentrate formulations on four types of organic leafy greens inoculated with S. enterica serovar Newport. The leafy greens tested included organic romaine and iceberg lettuce, and organic adult and baby spinach. Each leaf sample was washed, dip inoculated with Salmonella Newport (10(6) CFU/ml), and dried. Apple and olive extract formulations were prepared at 1, 3, and 5% concentrations, and hibiscus concentrates were prepared at 10, 20, and 30%. Inoculated leaves were immersed in the treatment solution for 2 min and individually incubated at 4 C. After incubation, samples were taken on days 0, 1, and 3 for enumeration of survivors. Our results showed that the antimicrobial activity was both concentration and time dependent. Olive extract exhibited the greatest antimicrobial activity, resulting in 2- to 3-log CFU/g reductions for each concentration and type of leafy green by day 3. Apple extract showed 1- to 2-log CFU/g reductions by day 3 on various leafy greens. Hibiscus concentrate showed an overall reduction of 1 log CFU/g for all leafy greens. The maximum reduction by hydrogen peroxide (3%) was about 1 log CFU/g. The antimicrobial activity was also tested on the background microflora of organic leafy greens, and reductions ranged from 0 to 2.8 log. This study demonstrates the potential of natural plant extract formulations to inactivate Salmonella Newport on organic leafy greens.

AB Data regarding Salmonella on raw poultry are very limited in China. The objective of this study was to determine the prevalence of Salmonella on raw poultry at the retail level in six provinces and two national cities in China. Whole chicken carcasses (n = 1,152) were collected from three types of retail markets (large, small, and wet). All samples were analyzed for the presence of Salmonella by using the U.S. Department of Agriculture, Food Safety Inspection Service method. Of 1,152 chicken samples, overall Salmonella prevalence was 52.2%. The highest prevalence was observed in Guangxi Province (65.3%), next in Guangdong Province (64.6%), and then in Beijing (63.9%), Shaanxi Province (50.7%), Henan Province (47.9%), Shanghai (44.4%), and Fujian Province (42.4%), and lowest prevalence was observed in Sichuan Province (38.9%). Salmonella prevalence was significantly different among the six provinces and two national cities. Salmonella prevalence was highest in the wet markets (54.4%) compared with the large markets (50.3%) and the small markets (52.1%), but differences were not significant (P > 0.05). Good manufacturing practices, good agricultural practices, and hazard analysis critical control point systems for Salmonella control in poultry production at the farm, processing, and retail level should be implemented.

AB Cumpylobacter spp. are nutritionally fastidious organisms that are sensitive to normal atmospheric oxygen levels and lack homologues of common cold shock genes. At first glance, these bacteria seem ill equipped to persist within food products under processing and storage conditions; however, they survive in numbers sufficient to cause the largest number of foodborne bacterial disease annually. A mechanism proposed to play a role in Cumpylobacter survival is the addition of polyphosphate-containing marinades during poultry processing. Campylobacter jejuni and Cumpylobacter coli strains incubated in chicken exudates collected from poultry treated with a marinade demonstrated considerable survival advantages (1 to 4 log CFU/ml) over the same strains incubated in chicken exudate from untreated birds. Polyphosphates, which constitute a large portion of the commercial poultry marinades, were shown to account for a majority of the observed influence of the marinades on Campylobacter survival. When six different food grade polyphosphates (disodium pyrophosphate, tetrasodium pyrophosphate, pentasodium triphosphate, sodium polyphosphate, monosodium phosphate, and trisodium phosphate) were utilized to compare the survival of Campylobacter strains in chicken exudate, significant differences were observed with regard to Campylobacter survival between the different polyphosphates. It was then determined that the addition of polyphosphates to chicken exudate increased the pH of the exudate, with the more sodiated polyphosphates increasing the pH to a greater degree than the less sodiated polyphosphates. It was confirmed that the change in pH mediated by polyphosphates is responsible for the observed increases in Campylobacter survival.

AB The objective of this work is to develop a mathematical model for evaluating the effect of temperature on the rate of microbial growth. The new mathematical model is derived by combination and modification of the Arrhenius equation and the Eyring-Polanyi transition theory. The new model, suitable for both suboptimal and the entire growth temperature ranges, was validated using a collection of 23 selected temperature-growth rate curves belonging to 5 groups of microorganisms, including Pseudomonas spp., Listeria monocytogenes, Salmonella spp., Clostridium perfringens, and Escherichia coli, from the published literature. The curve fitting is accomplished by nonlinear regression using the Levenberg-Marquardt algorithm. The resulting estimated growth rate (mu) values are highly correlated to the data collected from the literature (R(2) = 0.985, slope = 1.0, intercept = 0.0). The bias factor (B(f)) of the new model is very close to 1.0, while the accuracy factor (A(f))anges from 1.0 to 1.22 for most data sets. The new model is compared favorably with the Ratkowsky square root model and the Eyring equation. Even with more parameters, the Akaike information criterion, Bayesian information criterion, and mean square errors of the new model are not statistically different from the square root model and the Eyring equation, suggesting that the model can be used to describe the inherent relationship between temperature and microbial growth rates. The results of this work show that the new growth rate model is suitable for describing the effect of temperature on microbial growth rate.

AB Butter cream is an all-purpose icing that is used to both ice and decorate cakes. Cream icings contain up to 40% shortening. As consumers become aware of the need to reduce fat in their diet, the demand for healthy, flavorful, and low-fat food increases. High-amylose corn starch was cooked in an excess-steam jet cooker in the presence of oleic acid. Amylose formed helical inclusion complexes with the fatty acid. Shortening was added at different levels to jet-cooked starch. The resulting starch-lipid composites (SLC) had 0%, 8%, 16%, and 24% fat. The composites were used to substitute shortening in the preparation of cake icings with 1% to 13% fat. SLC icings were formulated by either keeping the total solids constant, or the starch and sugar to water ratio constant as the fat level was reduced. The effect of fat and formulation of shortening and SLC icings on the physical and rheological characteristics were studied. It was found that low-fat SLC icings can be prepared by optimizing the formulation.

AB The foodborne pathogen Staphylococcus aureus produces the virulent staphylococcal enterotoxin A (SEA), a single chain protein which consists of 233 amino acid residues with a molecular weight of 27078 Da. SEA is a superantigen that is reported to contribute to animal (mastitis) and human (emesis, diarrhea, atopic dermatitis, arthritis, and toxic shock) syndromes. Changes in the native structural integrity may inactivate the toxin by preventing molecular interaction with cell membrane receptor sites of their host cells. In the present study, we evaluated the ability of the pure olive compound 4-hydroxytyrosol and a commercial olive powder called Hidrox-12, prepared by freeze-drying olive juice, to inhibit S. aureus bacteria and SEA's biological activity. Dilutions of both test substances inactivated the pathogens. Two independent cell assays (BrdU incorporation into newly synthesized DNA and glycyl-phenylalanyl-aminofluorocoumarin proteolysis) demonstrated that the olive compound 4-hydroxytyrosol also inactivated the biological activity of SEA at concentrations that were not toxic to the spleen cells. However, efforts to determine inhibition of the toxin by Hidrox-12 were not successful because the olive powder was cytotoxic to the spleen cells at concentrations found to be effective against the bacteria. The results suggest that food-compatible and safe antitoxin olive compounds can be used to inactivate both pathogens and toxins produced by the pathogens.

AB The objective of this paper to conduct a parallel comparison of a new Belehradek-type growth rate (with an exponent of 1.5, or the Huang model), Ratkowsky square-root, and Ratkowsky square equations as secondary models for evaluating the effect of temperature on the growth of microorganisms. Growth rates of psychrotrophs and mesophiles were selected from the literature, and independently analyzed with the 3 models using nonlinear regression. Analysis of variance (ANOVA) was used to compare the means of growth rate (mu), estimated minimum temperature (T-min), approximate standard errors (SE) of T-min, model mean square errors (MSE), accuracy factor (A(f)), bias factor (B-f), relative residual errors (delta), Akaike information criterion (AICc), and Bayesian information criterion (BIC). Based on the estimated T-min values, the Huang model distinctively classified the bacteria into 2 groups (psychrotrophs and mesophiles). No significant difference (P > 0.05) was observed among the means of the mu values reported in the literature or estimated by the 3 models, suggesting that all 3 models were suitable for curve fitting. Nor was there any significant difference in MSE, SE, delta, A(f), B-f, AICc, and BIC. The T-min values estimated by the Huang model were significantly higher than those estimated by the Ratkowsky models, but were in closer agreement with the biological minimum temperatures for both psychrotrophs and mesophiles. The T-min values estimated by the Ratkowsky models systematically underestimated the minimum growth temperatures. In addition, statistical estimation showed that the mean exponent for the new Belehradek-type growth rate model may indeed be 1.5, further supporting the validity of the Huang model.

AB Foot-and-mouth disease virus (FMDV) outer capsid proteins 1B, 1C and 1D contribute to the virus serotype distribution and antigenic variants that exist within each of the seven serotypes. This study presents phylogenetic, genetic and antigenic analyses of South African Territories (SAT) serotypes prevalent in sub-Saharan Africa. Here, we show that the high levels of genetic diversity in the P1-coding region within the SAT serotypes are reflected in the antigenic properties of these viruses and therefore have implications for the selection of vaccine strains that would provide the best vaccine match against emerging viruses. Interestingly, although SAT1 and SAT2 viruses displayed similar genetic variation within each serotype (32 % variable amino acids), antigenic disparity, as measured by r(1)-values, was less pronounced for SAT1 viruses compared with SAT2 viruses within our dataset, emphasizing the high antigenic variation within the SAT2 serotype. Furthermore, we combined amino acid variation and the r1-values with crystallographic structural data and were able to predict areas on the surface of the FMD virion as antigenically relevant. These sites were mostly consistent with antigenic sites previously determined for types A, O and C using mAbs and escape mutant studies. Our methodology offers a quick alternative to determine antigenic relevant sites for FMDV field strains.

AB The contributions of precipitation and soil moisture observations to soil moisture skill in a land data assimilation system are assessed. Relative to baseline estimates from the Modern Era Retrospective-analysis for Research and Applications (MERRA), the study investigates soil moisture skill derived from (i) model forcing corrections based on large-scale, gauge- and satellite-based precipitation observations and (ii) assimilation of surface soil moisture retrievals from the Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E). Soil moisture skill (defined as the anomaly time series correlation coefficient R) is assessed using in situ observations in the continental United States at 37 single-profile sites within the Soil Climate Analysis Network (SCAN) for which skillful AMSR-E retrievals are available and at 4 USDA Agricultural Research Service ("Cal Val") watersheds with high-quality distributed sensor networks that measure soil moisture at the scale of land model and satellite estimates. The average skill of AMSR-E retrievals is R = 0.42 versus SCAN and R = 0.55 versus CalVal measurements. The skill of MERRA surface and root-zone soil moisture is R = 0.43 and R = 0.47, respectively, versus SCAN measurements. MERRA surface moisture skill is R = 0.56 versus CalVal measurements. Adding information from precipitation observations increases (surface and root zone) soil moisture skills by Delta R similar to 0.06. Assimilating AMSR-E retrievals increases soil moisture skills by Delta R similar to 0.08. Adding information from both sources increases soil moisture skills by Delta R similar to 0.13, which demonstrates that precipitation corrections and assimilation of satellite soil moisture retrievals contribute important and largely independent amounts of information.

ID ENSEMBLE KALMAN FILTER; SURFACE MODEL; PREDICTION; SCHEME; STATE
AB A weak constraint is introduced in ensemble Kalman filters to reduce the water budget imbalance that occurs in land data assimilation. Two versions of the weakly constrained filter, called the weakly constrained ensemble Kalman filter (WCEnKF) and the weakly constrained ensemble transform Kalman filter (WCETKF), are proposed. The strength of the weak constraint is adaptive in the sense that it depends on the statistical characteristics of the forecast ensemble. The resulting filters are applied to assimilate synthetic observations generated by the Noah land surface model over the Red Arkansas River basin. The data assimilation experiments demonstrate that, for all tested scenarios, the constrained filters produce analyses with nearly the same accuracy as unconstrained filters, but with much smaller water balance residuals than unconstrained filters.

AB Toxoplasma gondii oocysts are environmentally resistant and can survive outdoors for many months in dry and cold climates. In the present study, sporulation and survival of T. gondii oocysts was studied in different types of cat litters commercially available in the United States. Oocysts sporulated within 2-3 days in all types of cat litters and occasionally remained viable for 14 days. Results indicate that cat litter should be changed daily to prevent sporulation and infectivity to people.

AB Toxoplasma gondii was isolated from a feral guinea fowl (Numida meleagris) and domestic rabbits (Oryctologus cuniculus) from Brazil for the first time. Serum and brains from 10 guinea fowl and 21 rabbits from Brazil were examined for T gondii infection. Antibodies to T gondii were found in 2 of 10 fowl and 2 of 21 rabbits by the modified agglutination test (titer 1:25 or higher). Viable T gondii (designated TgNmBr1) was isolated from I of the 2 seropositive fowl by bioassay in mice but not from the 8 seronegative fowl by bioassay in cat. Viable T. gondii was isolated from both seropositive rabbits (designated TgRabbitBr1, TgRabbitBr2) by bioassay in mice from I and by bioassay in cat from the other. The TgRabbitBr1 strain was highly virulent for out-bred mice; mice fed 1 infective oocyst died of acute toxoplasmosis. The remaining 2 isolates were relatively avirulent for mice; lethal dose for mice was 10,000 oocysts. All 3 isolates were grown in cell culture, and tachyzoite-derived DNA were genotyped using 10 PCR-restriction fragment length polymorphism markers (SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico). The TgNmBr1 was found to be clonal Type II, a rare finding in Brazil in any host. The rabbit isolates were atypical, similar to isolates from cats from Brazil (TgRabbitBr1 was identical to TgCatBr5, and TgRabbitBr2 was identical to TgCatBr1, a common genotype in Brazil denoted type BrII). This is the first genetic characterization of T gondii isolates from the rabbits and guinea fowl in Brazil and the first host record for T gondii in the guinea fowl.

TI Seroprevalence of Toxoplasma gondii in Pigs, Sheep, Goats, and Cattle

SO JOURNAL OF PARASITOLOGY

DT Article
ID OOCYSTS; CYSTS; CATS
AB Prevalence of Toxoplasma gondii infection in pregnant women in Grenada is considered high. Little is known of the epidemiology of T. gondii infection in Caribbean Islands. Serum samples of 750 food animals in Grenada and Carriacou were tested for antibodies to T. gondii by the modified agglutination test (MAT). Antibodies to T. gondii (MAT, 1:25 or higher) were found in 23.1% of 247 pigs, 44.1% of 204 sheep, 42.8% of 180 goats, and 8.4% of 119 cattle. Seroprevalence increased with age, indicating postnatal acquisition of T. gondii. Antibody titers of 1:200 or higher were present in 65 of 90 seropositive sheep, 61 of 77 seropositive goats, and 23 of 57 seropositive pigs. However, none of the cattle had a MAT titer of 1:200, suggesting that bovines are a poor host for T. gondii. Results indicate that pigs, sheep, and goats could be important sources of T. gondii infection if their meat is consumed undercooked.

AB Feces were collected from 68 dairy cattle, 1 to 12 mo of age, on 12 farms in the municipality of Campos dos Goytacazes, Rio de Janeiro, Brazil, and examined for the presence of Cryptosporidium sp. All samples were subjected to molecular analysis by polymerase chain reaction (nested PCR) of the 18S rRNA. Four positive samples (4.54%) were sequenced and identified as Cryptosporidium undersold. This species represents a risk for Brazilian cattle because infection can affect cattle productivity. Moreover, C. andersoni is considered a zoonotic species.

AB Particulate matter (PM) emitted from cattle feedlots are thought to affect air quality in rural communities, yet little is known about factors controlling their emissions. The concentrations of PM (i.e., PM(2.5), PM(10), and total suspended particulates or TSP) upwind and downwind at two large cattle feedlots (KS1, KS2) in Kansas were measured with gravimetric samplers from May 2006 to October 2009 (at KS1) and from September 2007 to April 2008 (at KS2). The mean downwind and net (i.e., downwind - upwind) mass concentrations of PM(2.5), PM(10), and TSP varied seasonally, indicating the need for multiple-day, seasonal sampling. The downwind and net concentrations were closely related to the moisture content of the pen surface. The PM(2.5)/PM(10) and PM(2.5)/TSP ratios at the downwind sampling location were also related to the moisture content of the pen surface, humidity, and temperature. Measurement of the particle size distribution downwind of the feedlot with a cascade impactor showed geometric mean diameter ranging from 7 to 18 mu m, indicating that particles that were emitted from the feedlots were generally large in size.

AB Eighty years ago, Alexander Fleming described the antibiotic effects of a fungus that had contaminated his bacterial culture, kick starting the antimicrobial revolution. The fungus was later ascribed to a putatively globally distributed asexual species, Penicillium chrysogenum. Recently, the species has been shown to be genetically diverse, and possess mating-type genes. Here, phylogenetic and population genetic analyses show that this apparently ubiquitous fungus is actually composed of at least two genetically distinct species with only slight differences detected in physiology. We found each species in air and dust samples collected in and around St Mary's Hospital where Fleming worked. Genotyping of 30 markers across the genome showed that preserved fungal material from Fleming's laboratory was nearly identical to derived strains currently in culture collections and in the same distinct species as a wild progenitor strain of current penicillin producing industrial strains rather than the type species P. chrysogenum. Global samples of the two most common species were found to possess mating-type genes in a near 1:1 ratio, and show evidence of recombination with little geographic population subdivision evident. However, no hybridization was detected between the species despite an estimated time of divergence of less than 1 MYA. Growth studies showed significant interspecific inhibition by P. chrysogenum of the other common species, suggesting that competition may facilitate species maintenance despite globally overlapping distributions. Results highlight under-recognized diversity even among the best-known fungal groups and the potential for speciation despite overlapping distribution.

AB Cyanophycin is a poly(arginyl-aspartate) biopolymer produced and stored intracellularly by bacteria. Cyanophycin has been proposed as a renewable replacement for petrochemical-based industrial products. An abundant source of amino acids and nitrogen such as in the form of protein hydrolysates is needed for the biosynthesis of cyanophycin. Rendered proteins are largely used as a feed supplement in animal husbandry and aquaculture. New uses would expand the market size of this class of protein coproducts. We prepared and thoroughly characterized the hydrolysates of meat and bone meal, and proceeded to demonstrate for the first time that these hydrolysates could be used in the fermentative production of cyanophycin. Using the enzyme-hydrolyzed meat and bone meal preparation, we obtained crude cyanophycin product at 33-35% level of that produced using the reference casamino acids in both shake-flask and 10-L bioreactor fermentation studies. Polyacrylamide-gel electrophoresis of the cyanophycin under denaturing conditions showed the molecular weight of the isolated polyamide at 24 kDa. Our results open a new avenue for the utilization of rendered protein coproducts to produce the cyanophycin biopolymer.

AB Numerous evolutionary innovations were required to enable freshwater green algae to colonize terrestrial habitats and thereby initiate the evolution of land plants (embryophytes). These adaptations probably included changes in cell-wall composition and architecture that were to become essential for embryophyte development and radiation. However, it is not known to what extent the polymers that are characteristic of embryophyte cell walls, including pectins, hemicelluloses, glycoproteins and lignin, evolved in response to the demands of the terrestrial environment or whether they pre-existed in their algal ancestors. Here we show that members of the advanced charophycean green algae (CGA), including the Charales, Coleochaetales and Zygnematales, but not basal CGA (Klebsormidiales and Chlorokybales), have cell walls that are comparable in several respects to the primary walls of embryophytes. Moreover, we provide both chemical and immunocytochemical evidence that selected Coleochaete species have cell walls that contain small amounts of lignin or lignin-like polymers derived from radical coupling of hydroxycinnamyl alcohols. Thus, the ability to synthesize many of the components that characterize extant embryophyte walls evolved during divergence within CGA. Our study provides new insight into the evolutionary window during which the structurally complex walls of embryophytes originated, and the significance of the advanced CGA during these events.

AB ZnO/Nylon 6 nanofiber mats were prepared by an electrospinning-electrospraying hybrid process in which ZnO nanoparticles were dispersed on the surface of Nylon 6 nanofibers without becoming completely embedded. The prepared ZnO/Nylon 6 nanofiber mats were evaluated for their abilities to kill bacteria or inhibit their growth and to catalytically detoxify chemicals. Results showed that these ZnO/Nylon 6 nanofiber mats had excellent antibacterial efficiency (99.99%) against both the Gram-negative Escherichia coli and Gram-positive Bacillus cereus bacteria. In addition, they exhibited good detoxifying efficiency (95%) against paraoxon, a simulant of highly toxic chemicals. ZnO/Nylon 6 nanofiber mats were also deposited onto nylon/cotton woven fabrics and the nanofiber mats did not significantly affect the moisture vapor transmission rates and air permeability values of the fabrics. Therefore, ZnO/Nylon 6 nanofiber mats prepared by the electrospinning-electrospraying hybrid process are promising material candidates for protective applications.

AB The Agricultural Research Service of the U. S. Department of Agriculture conducts research on agricultural products and co-products where wool is a co-product of the American lamb industry. The ARS process, an alternative to conventional peroxide for bleaching and chlorination for shrinkproofing wool, was applied to bleach and control the dimensions of wool, wool/cotton, cotton, and viscose rayon fabrics. Conventional processes for bleaching and shrinkage control have limited economy due to high temperatures and long exposures, and their ecological acceptance is marginal. The ARS process is chemo-enzymatic with bleaching followed by biopolishing with shrinkproofing, both steps being applied at near-room-temperature conditions for 30-40 minutes to reach high levels of whiteness, softness, and dimensional stability. The novelty of the process involves the in situ formation of a hyper-peroxide bleach to achieve high whiteness with subsequent enzyme processing from a fresh bath to selectively treat only the surface scales of wool without damage to the inner cortex of the fiber. The Whiteness Index (WI) of wool and wool/cotton improved 63%-72% after bleaching alone and another similar to 2% increase after enzyme treatment; area shrinkage was less than 2%. The WI of cotton print cloth improved 60.5% by ARS bleaching compared to 64% by conventional bleaching. The process limited shrinkage of cotton knit to 4% and to less than 2% for cotton and viscose woven fabrics. The mechanical properties of all treated fabrics were retained. In a separate study, the process was applied at high concentration to convert wool jersey into parchmentized jersey with permanent stiffness and 45.5% increase in sheerness, as determined digital image analysis. ARS novel bleaching is a sustainable, facile, effective process for low-temperature bleaching with low energy consumption and low environmental impact. Wool jersey with sheerness, stiffness, and strength retention can be fabricated by treatment with highly concentrated ARS hyper-peroxide bleach.

AB Atmospheric stability conditions in the atmospheric surface layer control the distance and direction of transport of air contaminants. Near confined animal facilities, transport processes significantly impact air quality as these sites typically act as point sources of dust and odor constituents; however, little information is available on atmospheric stability effects. This study was conducted to assess year-round temporal patterns of atmospheric stability at a swine production facility and an adjacent commercial corn field (CF) in the US Midwest. Two towers of 10 and 20 m heights for continuous micrometeorological measurements were deployed within a CF and between swine buildings (BSB), respectively. Each tower was equipped with an eddy-covariance system at 6.8 m height, infrared thermometers, and six cup anemometers with thermocouples installed at log-distributed heights. Overall results from gradient Richardson number and Monin-Obukhov (z/L) calculations revealed a greater prevalence of unstable conditions for BSB compared with CF. During the 13-month measurement period, unstable cases (z/L ranging from -1 to -0.01) occurred 1.4 times more frequently for BSB than CF (52 vs. 39%, respectively), while stable cases (0.011-0.2) were 1.8 times more frequent for CF than BSB (24 vs. 14%, respectively). These patterns were partly associated with higher surface radiometric temperatures for BSB. Relatively greater diurnal heat capture at BSB (ground and roof surfaces) and a cooling effect in CF through active canopy transpiration during the daytime explain these z/L and radiometric temperature results. Prevalent diurnal atmospheric instability at BSB suggests enhanced ascendant vertical transport of air pollutants perhaps causing greater mixing/dilution with the atmospheric layer and/or their facilitated transport over greater distances when sorbed onto particles. This enhanced understanding of the spatio-temporal patterns of atmospheric stability can be subsequently applied in further studies for identifying effective odor mitigation strategies near commercial animal production facilities.

AB Natural herbicides approved in organic agriculture are primarily nonselective burn-down essential oils applied POST. Multiple applications are often required due to their low efficacy. To address this problem, the in vivo herbicidal activity of manuka oil, the essential oil distilled from manuka tree (Leptospermum scoparium J.R. and G. Forst), was tested on selected broadleaf and grass weeds. While manuka oil exhibited good POST activity when applied in combination with a commercial lemongrass oil-based herbicide, it ultimately demonstrated interesting PRE activity, providing control of large crabgrass seedlings at a rate of 3 L ha(-1). Manuka oil and its main active ingredient, leptospermone, were stable in soil for up to 7 d and had half-lives of 18 and 15 d, respectively. The systemic activity of manuka oil addresses many of the current limitations associated with natural herbicides. Additionally, its soil persistence opens up a multitude of new possibilities for the use of manuka oil as a tool for weed management and may be a potential bridge between traditional and organic agriculture.

AB Horseweed is a common pest in vineyards of the San Joaquin Valley (SJV) of California. Interest in controlling this weed has increased with the recent discovery of a glyphosate-resistant (GR) biotype that has been observed to be more vigorous than a glyphosate-susceptible (GS) biotype in the SJV. However, the impact that either biotype may have on grapevine growth has not been assessed. Therefore, two glasshouse experiments were conducted to characterize the competitiveness of GR and GS horseweed biotypes from the SJV with young grapevines. 'Syrah' grapevines grafted to Freedom rootstocks were planted in 8-L plastic pots, alone, or with a single GR or GS horseweed. Additional GR and GS horseweeds were also planted separately in individual pots, and all plants were grown for 14 and 16 wk in 2006 and 2007, respectively. Grapevines grown with either biotype of the weed produced fewer leaves and amassed approximately 20% less dry mass (DM) than vines grown alone. The GR biotype reduced grapevine stem DM and length by 30%, but the GS biotype did not. The GR biotype accumulated more than twice the DM as the GS biotype, whether in competition with grapevine or not. Grapevines reduced the total leaf number of both horseweed biotypes by almost 50% and aboveground DM of GR and GS biotypes by 50 and 75%, respectively. These preliminary findings indicate that competition from horseweed can substantially reduce the growth of young grapevines and that the GR biotype may be more competitive than the GS biotype.

AB Greenhouse studies were conducted to determine the relative salinity tolerance of foxtail barley and seven desirable pasture grasses. Grass species were reed canarygrass, timothy, altai wildrye, tall fescue, tall wheatgrass, orchardgrass, creeping meadow foxtail, and foxtail barley. Grasses were exposed to increasing electrical conductivity levels of NaCl and CaCl(2) salt solution over time. Grass species were compared using a cumulative value of salt exposure (EC(days)), which was calculated to account for the electrical conductivity (EC) and the time a plant was exposed at that level of conductivity. Salinity tolerance varied among grass species. Increasing EC significantly reduced plant biomass of all species. All grass species experienced a 50% biomass reduction (GR(50)) between 271 and 512 EC(days) in 2008 and between 297 and 575 EC(days) in 2009. Foxtail barley was among the most salt tolerant (GR(50) = 512 and 525 EC(days)), requiring the highest salt exposure in 2008 and the second-highest exposure in 2009 to reduce biomass 50%. Grass mortality increased with increasing EC levels. Reed canarygrass and timothy were most susceptible to increasing salinity, with 50% mortality (LD(50)) of both grass species occurring between 983 and 1,186 EC(days). Moderate salinity tolerance was exhibited by orchardgrass, which required 1,977 and 1,844 EC(days); creeping foxtail, which required 1,998 and 2,431 EC(days); and tall fescue, which required 2,501 and >2,840 EC(days) to LD(50) in 2008 and 2009, respectively. Foxtail barley, altai wildrye, and tall wheatgrass were most tolerant of salinity and persisted with little mortality occurring at 3,033 and 2,840 EC(days) in 2008 and 2009, respectively. All grass species with higher growth rates than foxtail barley and altai wildrye were more susceptible to salinity, with the exception of tall wheatgrass. Growth rates of foxtail barley and altai wildrye were less than they were for other grasses, suggesting that slower growth rates may aid in salinity tolerance.

AB Weed control in organic onion production is often difficult and expensive, requiring numerous cultivations and extensive hand weeding. Onion safety and weed control with mustard seed meal (MSM) derived from Sinapis alba was evaluated in greenhouse and field trials. MSM applied at 110, 220, and 440 g m(-2) severely injured onions and reduced onion stand by 25% or more when applied from planting to the one-leaf stage of onions in greenhouse trials. MSM derived from mustard cultivars 'IdaGold' and 'AC Pennant' reduced plant dry weight of redroot pigweed with an effective dose that provided 90% weed control (ED(90)) of 14.5 and 3.2 g m(-2), respectively, in greenhouse trials, whereas the ED(90) of MSM from a low-glucosinolate cultivar '00RN29D10' was 128 g m(-2), suggesting that glucosinolate content and ionic thiocyanate (SCN(-)) production contribute to phytotoxicity of MSM. In field trials, weed emergence, onion injury, and onion yield were recorded following single or three sequential applications of MSM from 1.1 to 4.5 MT ha(-1) beginning at the two-leaf stage of onions in 2008, 2009, and 2010. By 8 wk after treatment (WAT), onion injury following MSM sequential applications was 10% or less in all 3 yr. Combined over 2008 and 2009, 48 and 68% fewer weeds emerged 3 WAT with MSM at 2.2 and 4.5 MT ha(-1), respectively. In 2010, MSM at 2.2 and 4.5 MT ha(-1) reduced the number of weeds emerged 4 WAT by 91 and 76%, respectively. MSM treatment did not significantly affect onion yield or size in 2008 and 2009, but in 2010 onion total yield was reduced by 29% by three sequential applications of MSM at 2.2 MT ha(-1). MSM has potential to be used as a weed-suppressive amendment in organic production systems, but the risk of crop injury is substantial.

AB Assessing belowground plant interference in rice has been difficult in the past because intertwined weed and crop roots cannot be readily separated. A C-13 discrimination method has been developed to assess distribution of intermixed roots of barnyardgrass and rice in field soils, but the suitability of this approach for other rice weeds is not known. C-13 depletion levels in roots and leaves of rice were compared with those of 10 troublesome weed species grown in monoculture in the greenhouse or field. Included were C-4 tropical grasses: barnyardgrass, bearded sprangletop, Amazon sprangletop, broadleaf signalgrass, fall panicum, and large crabgrass; C-4 sedge, yellow nutsedge; and C-3 species: red rice, gooseweed, and redstem. Rice root delta C-13 levels averaged, similar to -28 parts per thousand, indicating that these roots are highly C-13-depleted. Root delta C-13 levels ranged from -12 parts per thousand to -17 parts per thousand among the tropical grasses, and were -10 parts per thousand in yellow nutsedge, indicating that these species were less C-13 depleted than rice, and were C-4 plants suitable for C-13 discrimination studies with rice. Among the C-4 species, bearded sprangletop and yellow nutsedge were most and least C-13 depleted, respectively. delta C-13 levels in shoot and root tissue of pot-grown plants averaged 6% greater for C-4 plants and 9% greater for rice in the field than in the greenhouse. In pots, shoots of rice typically were slightly more C-13 depleted than roots. A reverse trend was seen in most C-4 species, particularly for broadleaf signalgrass and plants sampled from field plots. Corrections derived from inputs including the total mass, carbon mass, carbon fraction, and delta C-13 levels of roots and soil increased greatly the accuracy of root mass estimates and increased slightly the accuracy of root delta C-13 estimates (similar to 0.6 to 0.9%) in samples containing soil. Similar corrective equations were derived for mixtures of rice and C-4 weed roots and soil, and are proposed as a labor-saving option in C-13 discrimination root studies.

AB Megasphaera elsdenii is a lactate-fermenting, obligately anaerobic bacterium commonly present in the gastrointestinal tracts of mammals, including humans. Swine M. elsdenii strains were previously shown to have high levels of tetracycline resistance (MIC = 64 to >256 mu g/ml) and to carry mosaic (recombinant) tetracycline resistance genes. Baby pigs inherit intestinal microbiota from the mother sow. In these investigations we addressed two questions. When do M. elsdenii strains from the sow colonize baby pigs? Can five antibiotic-sensitive M. elsdenii strains administered intragastrically to newborn pigs affect natural colonization of the piglets by antibiotic-resistant (AR) M. elsdenii strains from the mother? M. elsdenii natural colonization of newborn pigs was undetectable (<10(4) CFU/g [wet weight] of feces) prior to weaning (20 days after birth). After weaning, all pigs became colonized (4 x 10(5) to 2 x 10(8) CFU/g feces). In a separate study, 61% (76/125) of M. elsdenii isolates from a gravid sow never exposed to antibiotics were resistant to chlortetracycline, ampicillin, or tylosin. The inoculation of the sow's offspring with mixtures of M. elsdenii antibiotic-sensitive strains prevented colonization of the offspring by maternal AR strains until at least 11 days postweaning. At 25 and 53 days postweaning, however, AR strains predominated. Antibiotic susceptibility phenotypes and single nucleotide polymorphism (SNP)-based identities of M. elsdenii isolated from sow and offspring were unexpectedly diverse. These results suggest that dosing newborn piglets with M. elsdenii antibiotic-sensitive strains delays but does not prevent colonization by maternal resistant strains. M. elsdenii subspecies diversity offers an explanation for the persistence of resistant strains in the absence of antibiotic selection.

AB Infestations of two stem borers, Eoreuma loftini (Dyar) and Diatraea saccharalis (F.) (Lepidoptera: Crambidae), were compared in noncrop grasses adjacent to rice (Oryza sativa L.) fields. Three farms in the Texas rice Gulf Coast production area were surveyed every 6-8 wk between 2007 and 2009 using quadrat sampling along transects. Although D. saccharalis densities were relatively low, E. loftini average densities ranged from 0.3 to 5.7 immatures per m(2) throughout the 2-yr period. Early annual grasses including ryegrass, Lolium spp., and brome, Bromus spp., were infested during the spring, whereas the perennial johnsongrass, Sorghum halepense (L.) Pers., and Vasey's grass, Paspalum urvillei Steud., were infested throughout the year. Johnsongrass was the most prevalent host (41-78% relative abundance), but Vasey's grass (13-40% relative abundance) harbored as much as 62% of the recovered E. loftini immatures (during the winter). Young rice in newly planted fields did not host stem borers before June. April sampling in fallow rice fields showed that any available live grass material, volunteer rice or weed, can serve as a host during the spring. Our study suggests that noncrop grasses are year-round sources of E. loftini in Texas rice agroecosystems and may increase pest populations.

AB In southeastern United States farmscapes, corn, Zea mays L., is often closely associated with peanut, (Arachis hypogaea L.), cotton, (Gossypium hirsutum L.), or both. The objective of this 3-yr on-farm study was to examine the influence of corn on stink bugs (Heteroptera: Pentatomidae), Nezara viridula (L.), and Euschistus serous (Say), in subsequent crops in these farmscapes. Adults of both stink bug species entered corn first, and seasonal occurrence of stink bug eggs, nymphs, and adults indicated that corn was a suitable host plant for adult survival and nymphal development to adults. Stink bug females generally oviposited on cotton or peanut near the interface, or common boundary, of the farmscape before senescence of corn, availability of a new food, or both. Adult stink bugs dispersed from crop to crop at the interface of a farmscape in response to senescence of corn, availability of new food, or both. In corn-cotton farmscapes, adult stink bugs dispersed from senescing corn into cotton to feed on bolls (fruit). In corn-peanut farmscapes, adult stink bugs dispersed from senescing corn into peanut, which apparently played a role in nymphal development in these farmscapes. In the corn-cotton-peanut farmscape, stink bug nymphs and adults dispersed from peanut into cotton in response to newly available food, not senescence of peanut. Stink bug dispersal into cotton resulted in severe boll damage. In conclusion, N. viridula and E. serous are generalist feeders that exhibit edge-mediated dispersal from corn into subsequent adjacent crops in corn-cotton, corn-peanut, and corn-peanut-cotton farmscapes to take advantage of suitable resources available in time and space for oviposition, nymphal development, and adult survival. Management strategies for crops in this region need to be designed to break the cycle of stink bug production, dispersal, and expansion by exploiting their edge-mediated movement and host plant preferences.

AB The mean height and standard deviation (SD) of flight is estimated for over 100 insect species from their catches on several trap heights reported in the literature. The iterative equations for calculating mean height and SD are presented. The mean flight height for 95% of the studies varied from 0.17 to 5.40 m, and the SD from 0.12 to 3.83 m. The relationship between SD and mean flight height (X) was SD = 0.711X(-0.7849), n = 123, R(2) = 0.63. In addition, the vertical trap catches were fit to normal distributions and analyzed for skew and kurtosis. The SD was used to calculate an effective flight layer used in transforming the spherical effective attraction radius (EAR) of pheromone-baited traps into a circular EAR(c) for use in two-dimensional encounter rate models of mass trapping and mating disruption using semiochemicals. The EAR/EAR(c) also serves to reveal the attractive strength and efficacy of putative pheromone blends. To determine the reliability of mean flight height and SD calculations from field trapping data, simulations of flying insects in three dimensions (3D) were performed. The simulations used an algorithm that caused individuals to roam freely at random but such that the population distributed vertically according to a normal distribution of specified mean and SD. Within this 3D arena, spherical traps were placed at various heights to determine the effects on catch and SD. The results indicate that data from previous field studies, when analyzed by the iterative equations, should provide good estimates of the population mean height and SD of flight.

AB Effective methods for early detection of newly established, low density emerald ash borer (Agrilus planipennis Fairmaire) infestations are critically needed in North America. We assessed adult A. planipennis captures on four types of traps in a 16-ha site in central Michigan. The site was divided into 16 blocks, each comprised of four 50- by 50-m cells. Green ash trees (Fraxinus pennsylvanica Marshall) were inventoried by diameter class and ash phloem area was estimated for each cell. One trap type was randomly assigned to each cell in each block. Because initial sampling showed that A. planipennis density was extremely low, infested ash logs were introduced into the center of the site. In total, 87 beetles were captured during the summer. Purple double-decker traps baited with a blend of ash leaf volatiles, Manuka oil, and ethanol captured 65% of all A. planipennis beetles. Similarly baited, green double-decker traps captured 18% of the beetles, whereas sticky bands on girdled trees captured 11% of the beetles. Purple traps baited with Manuka oil and suspended in the canopies of live ash trees captured only 5% of the beetles. At least one beetle was captured on 81% of the purple double-decker traps, 56% of the green double-decker traps, 42% of sticky bands, and 25% of the canopy traps. Abundance of ash phloem near traps had no effect on captures and trap location and sun exposure had only weak effects on captures. Twelve girdled and 29 nongirdled trees were felled and sampled in winter. Current-year larvae were present in 100% of the girdled trees and 72% of the nongirdled trees, but larval density was five times higher on girdled than nongirdled trees.

AB Cost-effective detection of invasive ant colonies before establishment in new ranges is imperative for the protection of national borders and reducing their global impact. We examined the sampling efficiency of food-baits and pitfall traps (baited and nonbaited) in detecting isolated red imported fire ant (Solenopsis invicta Buren) nests in multiple environments in Gainesville, FL. Fire ants demonstrated a significantly higher preference for a mixed protein food type (hotdog or ground meat combined with sweet peanut butter) than for the sugar or water baits offered. Foraging distance success was a function of colony size, detection trap used, and surveillance duration. Colony gyne number did not influence detection success. Workers from small nests (0- to 15-cm mound diameter) traveled no >3 m to a food source, whereas large colonies (>30-cm mound diameter) traveled up to 17 m. Baited pitfall traps performed best at detecting incipient ant colonies followed by nonbaited pitfall traps then food baits, whereas food baits performed well when trying to detect large colonies. These results were used to create an interactive model in Microsoft Excel, whereby surveillance managers can alter trap type, density, and duration parameters to estimate the probability of detecting specified or unknown S. invicta colony sizes. This model will support decision makers who need to balance the sampling cost and risk of failure to detect fire ant colonies.

AB We studied the ability of Tenebrio molitor L. (Coleoptera: Tenebrionidae) to self-select optimal ratios of two dietary components to approach nutritional balance and maximum fitness. Relative consumption of wheat bran and dry potato flakes was determined among larvae feeding on four different ratios of these components (10, 20, 30, and 40% potato). Groups of early instars were provided with a measured amount of food and the consumption of each diet component was measured at the end of 4 wk and again 3 wk later. Consumption of diet components by T. molitor larvae deviated significantly from expected ratios indicating nonrandom self-selection. Mean percentages of dry potato consumed were 11.98, 19.16, 19.02, and 19.27% and 11.89, 20.48, 24.67, and 25.97% during the first and second experimental periods for diets with 10, 20, 30, and 40% potato, respectively. Life table analysis was used to determine the fitness of T. molitor developing in the four diet mixtures in a no-choice experiment. The diets were compared among each other and a control diet of wheat bran only. Doubling time was significantly shorter in groups consuming 10 and 20% potato than the control and longer in groups feeding on 30 and 40% potato. The self-selected ratios of the two diet components approached 20% potato, which was the best ratio for development and second best for population growth. Our findings show dietary self-selection behavior in T. molitor larvae, and these findings may lead to new methods for optimizing dietary supplements for T. molitor.

AB Population structure dictates the evolution of each population, and thus, the species as a whole. Incorporating spatial variables with population genetic statistics allows for greater discovery beyond traditional population genetics alone and can inform management decisions. The understanding of population structure in Hessian fly, Mayetiola destructor (Say), a pest of wheat, has been limited in the past. We scored 14 microsatellite loci from 12 collections of Hessian fly in the southeastern United States. Through Bayesian clustering analysis, we found two major populations of Hessian fly covering the entire southeastern United States. We evaluated correlations between agriculturally significant spatial variables and population genetic differentiation to test if genetic structure has an ecological component in a wheat agro-ecosystem. Our results suggest the total amount of alternative host plants in the county may be driving some genetic differentiation. Although planting date may also be influential, geographic distance, mean annual temperature, and harvested wheat for grain do not seem to be contributing factors. The ecological or spatial component to population structure, however, may be minimal compared to factors such as genetic drift.

AB The greenbug aphid, Schizaphis graminum (Rondani) was introduced into the United States in the late 1880s, and quickly was established as a pest of wheat, oat, and barley. Sorghum was also a host, but it was not until 1968 that greenbug became a serious pest of it as well. The most effective control method is the planting of resistant varieties; however, the occurrence of greenbug biotypes has hampered the development and use of plant resistance as a management technique. Until the 1990s, the evolutionary status of greenbug biotypes was obscure. Four mtDNA cytochrome oxidase subunit I (COI) haplotypes were previously identified, suggesting that S. graminum sensu lato was comprised of host-adapted races. To elucidate the current evolutionary and taxonomic status of the greenbug and its biotypes, two nuclear genes and introns were sequenced; cytochrome c (CytC) and elongation factor I-alpha (EF1-alpha). Phylogenetic analysis of CytC sequences were in complete agreement with COI sequences and demonstrated three distinct evolutionary lineages in S. graminum. EF1-alpha DNA sequences were in partial agreement with COI and CytC sequences, and demonstrated two distinct evolutionary lineages. Host-adapted races in greenbug are sympatric and appear reproductively isolated. Agricultural biotypes in S. graminum likely arose by genetic recombination via meiosis during sexual reproduction within host-races. The 1968 greenbug outbreak on sorghum was the result of the introduction of a host race adapted to sorghum, and not selection by host resistance genes in crops.

AB Blueberries have recently been reported to reduce atherosclerotic lesion progression in apoE deficient (apoE(-/-)) mice. However, the underlying mechanisms are not fully understood. The objective of this study was to determine whether lowbush blueberries altered scavenger receptor expression and foam cell formation in apoE(-/-) mice. ApoE(-/-) mice were fed AIN-93 diet (CD) or CD formulated to contain 1% freeze-dried lowbush blueberries (BB) for 20 weeks. Gene expression and protein levels of scavenger receptor CD36 and SR-A in aorta and thioglycollate-elicited peritoneal macrophages (PM) were lower in mice fed BB (P < 0.05). In the second experiment, apoE(-/-) mice were fed CD or BB for 5 weeks. PM were collected and cultured. Gene expression and protein levels of CD36 and SR-A were found to be lower in PM of BB fed mice (P < 0.05). In PM from BB fed mice, fewer oxLDL-induced foam cells were formed compared to those from mice fed CD. Gene expression and protein levels of PPAR gamma were lower in the PM of BB fed mice (P < 0.05). Detectable isomers of hydroxyoctadecadienoic acids (HODEs) and hydroxyeicosatetraenoic acid (HETEs) were also lower in the PM of BB fed mice (P < 0.05 or P < 0.01). In conclusion, BB inhibited expression of the two major scavenger receptors CD36 and SR-A in PM of apoE(-/-) mice, at least in part through down-regulating PPAR gamma and reducing its endogenous ligands HODEs and HETEs. We proposed that BB mediated reduction of scavenger receptor expression and attenuation of oxLDL-induced foam cell formation in PM of apoE(-/-) mice are important mechanisms of the athero-protective effects of BB.

AB I use a representative sample of coffee growing households in southern Mexico to estimate the price premium and gross income gain from participating in Fair Trade-organic markets through grower cooperatives. For the 2004-2005 season, FT-organic growers received an average premium of 12.8 cents per pound. yielding a gross income gain of 5% of total household income or about 26 dollars per household member. The gain is net of the costs of cooperative participation but not of other costs incurred to become certified and suggests that price premiums alone have a limited potential to increase household returns from growing coffee. More broadly speaking, the finding raises questions about the persistence of substantial price premiums associated with social or environmental labeling initiatives. Published by Elsevier Ltd.

ID ECOSYSTEM STRUCTURE; FOREST
AB Current markets and international agreements for reducing emissions from deforestation and forest degradation (REDD) rely on carbon (C) monitoring techniques. Combining field measurements, airborne light detection and ranging (LiDAR)-based observations, and satellite-based imagery, we developed a 30-meter-resolution map of aboveground C density spanning 40 vegetation types found on the million-hectare Island of Hawaii. We estimate a total of 28.3 teragrams of C sequestered in aboveground woody vegetation on the island, which is 56% lower than Intergovernmental Panel on Climate Change estimates that do not resolve C variation at fine spatial scales. The approach reveals fundamental ecological controls over C storage, including climate, introduced species, and land-use change, and provides a fourfold decrease in regional costs of C measurement over field sampling alone.

UNITED-STATES; REGIONAL PROCESSES; NATIONAL-PARK; USA; CLIMATE;

AB Anticipating future forest-fire regimes under changing climate requires that scientists and natural resource managers understand the factors that control fire across space and time. Fire scars - proxy records of fires, formed in the growth rings of long-lived trees - provide an annually accurate window into past low-severity fire regimes. In western North America, networks of the fire-scar records spanning centuries to millennia now include hundreds to thousands of trees sampled across hundreds to many thousands of hectares. Development of these local and regional fire-scar networks has created a new data type for ecologists interested in landscape and climate regulation of ecosystem processes - which, for example, may help to explain why forest fires are widespread during certain years but not others. These data also offer crucial reference information on fire as a dynamic landscape process for use in ecosystem management, especially when managing for forest structure and resilience to climate change.

AB Context: Mono- and polyunsaturated fats may have opposing effects on vitamin D absorption.
Objective: The purpose of this study was to determine whether intakes of different dietary fats are associated with the increase in serum 25-hydroxyvitamin D (25OHD) after supplementation with vitamin D-3.
Design, Setting, and Participants: This analysis was conducted in the active treatment arm of a randomized, double-blind, placebo-controlled trial of vitamin D and calcium supplementation to prevent bone loss and fracture. Subjects included 152 healthy men and women age 65 and older who were assigned to 700 IU/d vitamin D-3 and 500 mg/d calcium. Intakes of monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), and saturated fatty acids (SFA) were estimated by food frequency questionnaire.
Main Outcome Measure: The change in plasma 25OHD during 2 yr vitamin D and calcium supplementation was assessed.
Results: The change in plasma 25OHD (nanograms per milliliter) during vitamin D supplementation was positively associated with MUFA, (beta = 0.94; P = 0.016), negatively associated with PUFA, (beta = -0.93; P = 0.038), and positively associated with the MUFA/PUFA ratio (beta = 6.46; P = 0.014).
Conclusion: The fat composition of the diet may influence the 25OHD response to supplemental vitamin D-3. Diets rich in MUFA may improve and those rich in PUFA may reduce the effectiveness of vitamin D-3 supplements in healthy older adults. More studies are needed to confirm these findings.

AB Context: Dyslipidemia increases the risk of cardiovascular disease in obesity. Peroxisome proliferator-activated receptor (PPAR)-delta agonists decrease plasma triglycerides and increase high-density lipoprotein (HDL)-cholesterol in humans.
Objective: The aim of the study was to examine the effect of GW501516, a PPAR-delta agonist, on lipoprotein metabolism.
Design, Setting, and Intervention: We conducted a randomized, double-blind, crossover trial of 6-wk intervention periods with placebo or GW501516 (2.5 mg/d), with 2-wk placebo washout between treatment periods.
Participants: We recruited 13 dyslipidemic men with central obesity from the general community.
Main Outcome Measures: We measured the kinetics of very low-density lipoprotein (VLDL)-, intermediate-density lipoprotein-, and low-density lipoprotein (LDL)-apolipoprotein (apo) B-100, plasma apoC-III, and high-density lipoprotein (HDL) particles (LpA-I and LpA-I: A-II). Results: GW501516 decreased plasma triglycerides, fatty acid, apoB-100, and apoB-48 concentrations. GW501516 decreased the concentrations of VLDL-apoB by increasing its fractional catabolism and of apoC-III by decreasing its production rate (P < 0.05). GW501516 reduced VLDL-to-LDL conversion and LDL-apoB production. GW501516 increased HDL-cholesterol, apoA-II, and LpA-I: A-II concentrations by increasing apoA-II and LpA-I: A-II production (P < 0.05). GW501516 decreased cholesteryl ester transfer protein activity, and this was paralleled by falls in the triglyceride content of VLDL, LDL, and HDL and the cholesterol content of VLDL and LDL.
Conclusions: GW501516 increased the hepatic removal of VLDL particles, which might have resulted from decreased apoC-III concentration. GW501516 increased apoA-II production, resulting in an increased concentration of LpA-I: A-II particles. This study elucidates the mechanism of action of this PPAR-delta agonist on lipoprotein metabolism and supports its potential use in treating dyslipidemia in obesity.

AB Context: The American Heart Association Nutrition Committee recommends women and men consume no more than 100 and 150 kcal of added sugar per day, respectively, whereas the Dietary Guidelines for Americans, 2010, suggests a maximal added sugar intake of 25% or less of total energy.
Objective: To address this discrepancy, we compared the effects of consuming glucose, fructose, or high-fructose corn syrup (HFCS) at 25% of energy requirements (E) on risk factors for cardiovascular disease.
Participants, Design and Setting, and Intervention: Forty-eight adults (aged 18-40 yr; body mass index 18-35 kg/m(2)) resided at the Clinical Research Center for 3.5 d of baseline testing while consuming energy-balanced diets containing 55% E complex carbohydrate. For 12 outpatient days, they consumed usual ad libitum diets along with three servings per day of glucose, fructose, or HFCS-sweetened beverages (n = 16/group), which provided 25% E requirements. Subjects then consumed energy-balanced diets containing 25% E sugar-sweetened beverages/30% E complex carbohydrate during 3.5 d of inpatient intervention testing.
Main Outcome Measures: Twenty-four-hour triglyceride area under the curve, fasting plasma low-density lipoprotein (LDL), and apolipoprotein B (apoB) concentrations were measured.
Results: Twenty-four-hour triglyceride area under the curve was increased compared with baseline during consumption of fructose (+4.7 +/- 1.2 mmol/liter x 24 h, P = 0.0032) and HFCS (+1.8 +/- 1.4 mmol/liter x 24 h, P = 0.035) but not glucose (-1.9 +/- 0.9 mmol/liter x 24 h, P = 0.14). Fasting LDL and apoB concentrations were increased during consumption of fructose (LDL: +0.29 +/- 0.082 mmol/liter, P = 0.0023; apoB: +0.093 +/- 0.022 g/liter, P = 0.0005) and HFCS (LDL: +0.42 +/- 0.11 mmol/liter, P < 0.0001; apoB: +0.12 +/- 0.031 g/liter, P < 0.0001) but not glucose (LDL: +0.012 +/- 0.071 mmol/liter, P = 0.86; apoB: +0.0097 +/- 0.019 g/liter, P = 0.90).
Conclusions: Consumption of HFCS-sweetened beverages for 2 wk at 25% E increased risk factors for cardiovascular disease comparably with fructose and more than glucose in young adults. (J Clin Endocrinol Metab 96: E1596-E1605, 2011)

AB Small firms, through their flexibility advantages and closeness to customers, potentially can increase their sales volume in economic downturns. The decline in U.S. housing construction (beginning in 2006) provided an opportunity to develop and test four hypotheses predicting the attributes and marketing actions associated with successful companies supplying housing markets. Smaller firms and those producing made-to-order products were most likely to have realized increased sales volume. These successful firms were not engaged in several marketing actions hypothesized to increase sales volume in a declining market. Small firm competitiveness was based more on working closely with customers to produce fully customized products.

AB Plants in nutrient-poor environments typically have low foliar nitrogen (N) concentrations, long-lived tissues with leaf traits designed to use nutrients efficiently, and low rates of photosynthesis. We postulated that increasing N availability due to atmospheric deposition would increase photosynthetic capacity, foliar N, and specific leaf area (SLA) of bog shrubs. We measured photosynthesis, foliar chemistry and leaf morphology in three ericaceous shrubs (Vaccinium myrtilloides, Ledum groenlandicum and Chamaedaphne calyculata) in a long-term fertilization experiment at Mer Bleue bog, Ontario, Canada, with a background deposition of 0.8 g N m(-2) a(-1). While biomass and chlorophyll concentrations increased in the highest nutrient treatment for C. calyculata, we found no change in the rates of light-saturated photosynthesis (A(max)), carboxylation (V-cmax), or SLA with nutrient (N with and without PK) addition, with the exception of a weak positive correlation between foliar N and A(max) for C. calyculata, and higher V-cmax in L. groenlandicum with low nutrient addition. We found negative correlations between photosynthetic N use efficiency (PNUE) and foliar N, accompanied by a species-specific increase in one or more amino acids, which may be a sign of excess N availability and/or a mechanism to reduce ammonium (NH4) toxicity. We also observed a decrease in foliar soluble Ca and Mg concentrations, essential minerals for plant growth, but no change in polyamines, indicators of physiological stress under conditions of high N accumulation. These results suggest that plants adapted to low-nutrient environments do not shift their resource allocation to photosynthetic processes, even after reaching N sufficiency, but instead store the excess N in organic compounds for future use. In the long term, bog species may not be able to take advantage of elevated nutrients, resulting in them being replaced by species that are better adapted to a higher nutrient environment.

AB Exotic plants are generally considered a serious problem in wildlands around the globe. However, some argue that the impacts of exotic plants have been exaggerated and that biodiversity and other important plant community characteristics are commonly improved with invasion. Thus, disagreement exists among ecologists as to the relationship of exotic plants with biodiversity and native plant communities. A better understanding of the relationships between exotic plants and native plant communities is needed to improve funding allocation and legislation regarding exotic plants, and justify and prioritize invasion management. To evaluate these relationships, 65 shrub-bunchgrass plant communities with varying densities of an exotic annual grass, Taeniatherum caput-medusae (L.) Nevski (medusahead), were sampled across 160,000 ha in southeastern Oregon, United States. Environmental factors were generally not correlated with plant community characteristics when exotic annual grass density was included in models. Plant diversity and species richness were negatively correlated with exotic annual grass density. Exotic annual grass density explained 62% of the variation in plant diversity. All native plant functional groups, except annual forbs, exhibited a negative relationship with T. caput-medusae. The results of this study suggest that T. caput-medusae invasions probably have substantial negative impacts on biodiversity and native plant communities. The strength of the relationships between plant community characteristics and T. caput-medusae density suggests that some exotic plants are a major force of change in plant communities and subsequently threaten ecosystem functions and processes. However, experimental studies are needed to fully substantiate that annual grass invasion is the cause of these observed correlations.

AB Differences in resource acquisition between native and exotic plants is one hypothesis to explain invasive plant success. Mechanisms include greater resource acquisition rates and greater plasticity in resource acquisition by invasive exotic species compared to non-invasive natives. We assess the support for these mechanisms by comparing nitrate acquisition and growth of invasive annual and perennial grass seedlings in western North America. Two invasive exotic grasses (Bromus tectorum and Taeniatherum caput-medusae) and three perennial native and exotic grasses (Pseudoroegneria spicata, Elymus elymoides, and Agropyron cristatum) were grown at various temperatures typical of autumn and springtime when resource are abundant and dominance is determined by rapid growth and acquisition of resources. Bromus tectorum and perennial grasses had similar rates of nitrate acquisition at low temperature, but acquisition by B. tectorum significantly exceeded perennial grasses at higher temperature. Consequently, B. tectorum had the highest acquisition plasticity, showcasing its ability to take advantage of transient warm periods in autumn and spring. Nitrate acquisition by perennial grasses was limited either by root production or rate of acquisition per unit root mass, suggesting a trade-off between nutrient acquisition and allocation of growth to structural tissues. Our results indicate the importance of plasticity in resource acquisition when temperatures are warm such as following autumn emergence by B. tectorum. Highly flexible and opportunistic nitrate acquisition appears to be a mechanism whereby invasive annual grasses exploit soil nitrogen that perennials cannot use.

AB Critical path analysis (CPA) is a method for estimating macroscopic transport coefficients of heterogeneous materials that are highly disordered at the micro-scale. Developed originally to model conduction in semiconductors, numerous researchers have noted that CPA might also have relevance to flow and transport processes in porous media. However, the results of several numerical investigations of critical path analysis on pore network models raise questions about the applicability of CPA to porous media. Among other things, these studies found that (i) in well-connected 3D networks, CPA predictions were inaccurate and became worse when heterogeneity was increased; and (ii) CPA could not fully explain the transport properties of 2D networks. To better understand the applicability of CPA to porous media, we made numerical computations of permeability and electrical conductivity on 2D and 3D networks with differing pore-size distributions and geometries. A new CPA model for the relationship between the permeability and electrical conductivity was found to be in good agreement with numerical data, and to be a significant improvement over a classical CPA model. In sufficiently disordered 3D networks, the new CPA prediction was within +/- 20% of the true value, and was nearly optimal in terms of minimizing the squared prediction errors across differing network configurations. The agreement of CPA predictions with 2D network computations was similarly good, although 2D networks are in general not well-suited for evaluating CPA. Numerical transport coefficients derived for regular 3D networks of slit-shaped pores were found to be in better agreement with experimental data from rock samples than were coefficients derived for networks of cylindrical pores.

Roots and rhizomes of black cohosh, a native Appalachian forest herb, are extensively harvested for treatment of menopausal symptoms. As nearly all cohosh sold commercially is collected from natural populations, the potential for harvest impacts is considerable. To better understand wild-harvest impacts and the likelihood of post-harvest recovery, we studied the effects of 2 to 4 y of experimental harvest on natural black cohosh populations in the George Washington-Jefferson National Forest in southwest Virginia. After 2 to 3 y of intense harvest (66% plant removal), we found significant reductions in foliage area, stem production, and mean and maximum plant height. The effects of moderately intense harvest (33%) were less clear, producing growth measures between, yet not significantly different from, control (non-harvest) and intensively harvested plots. After three successive years of experimental harvest, harvest treatments were terminated to assess population regrowth. Populations experiencing intensive harvest showed no evidence of recovery after 1 y. Results suggest that black cohosh is highly responsive to harvest intensity and that low to moderate harvest intensities and/or longer recovery periods will be necessary for prolonged and sustainable harvests at our study site. While this study has increased our understanding of harvest impacts on black cohosh, continued assessment is needed to determine the sustainability of low to moderate harvest levels and minimum recovery periods necessary for population reestablishment.

AB Background: A number of unsaturated fatty acids and a few saturated branched-chain fatty acids have been reported to exhibit anticancer activity. Materials and Methods: In previously reported research, several novel branched-chain derivatives (methyl, n-butyl, phenyl) of methyl oleate were produced by bromination in the allylic position and subsequent treatment with organocuprate reagents. These compounds and their free acid counterparts were tested in vitro for their antiproliferative activities against two cancer cell lines: MCF-7 (human breast) and HT-29 (human colon). In addition, two sets of isomeric tertiary alcohols obtained as side-products in the synthesis of the branched-chain derivatives were evaluated. Testing was performed at three concentration levels (50, 100, and 200 ppm) in dimethyl sulfoxide (DMSO). Results: The greatest growth inhibitory activity was exhibited by the branched phenyl derivative of oleic acid, with IC(50) at 48 ppm against both MCF-7 and HT-29. The branched n-butyl derivative of oleic acid also exhibited significant antiproliferative activity, with IC(50) at 82 ppm against MCF-7 and 77 ppm against HT-29. Conclusion: The observed potent anticancer activity of the n-butyl and phenyl derivatives indicates that certain synthetic branched-chain unsaturated fatty acids have potential in the treatment of cancer and further research is warranted.

AB The present study investigated the effects of non-motorized voluntary running on experimental metastasis of B16BL/6 melanoma and spontaneous metastasis of Lewis lung carcinoma (LLC) in male C57BL/6 mice. After 9 weeks of running, mice (n=30 per group) received an intravenous injection of B16BL/6 cells or a subcutaneous injection of LLC cells, and then they were continued with their running activities. Experiments were terminated 2 weeks after the intravenous injection of B16BL/6 cells or 2 weeks after surgical removal of the primary tumor from mice subcutaneously injected with LLC cells. Mice in the running group ran an average of 4-6 km/day for the duration of the experiment. Voluntary running reduced body weight compared with the sedentary controls, but there were no differences in the number and size of lung metastases between groups with either model. Voluntary running significantly reduced plasma insulin and leptin levels and increased adiponectin level in mice with and without LLC compared with the sedentary controls. Having LLC significantly increased plasma concentrations of vascular endothelial growth factor (VEGF), platelet-derived growth factor-BB (PDGF-BB), PDGF-AB and monocyte chemotactic protein-1 (MCP-1) in mice. Voluntary running significantly increased plasma PDGF-BB and PDGF-AB, but not VEGF and MCP-1, in mice with LLC compared to their sedentary counterparts. In conclusion, non-motorized voluntary running was favorable, to body weight and the expression of related adipokines, but at 4-6 km/day it did not affect either experimental or spontaneous metastasis in mice.

AB Native aspen (Populus tremuloides) was pretreated using sulfuric acid and sodium bisulfite (SPORL) and dilute sulfuric acid alone (DA). Simultaneous enzymatic saccharification and fermentation (SSF) was conducted at 18% solids using commercial enzymes with cellulase loadings ranging from 6 to 15 FPU/g glucan and Saccharomyces cerevisiae Y5. Compared with DA pretreatment, the SPORL pretreatment reduced the energy required for wood chip size-reduction, and reduced mixing energy of the resultant substrate for solid liquefaction. Approximately 60% more ethanol was produced from the solid SPORL substrate (211 L/ton wood at 59 g/L with SSF efficiency of 76%) than from the solid DA substrate (133 L/ton wood at 35 g/L with SSF efficiency 47%) at a cellulase loading of 10 FPU/g glucan after 120 h. When the cellulase loading was increased to 15 FPU/g glucan on the DA substrate, the ethanol yield still remained lower than the SPORL substrate at 10 FPU/g glucan. Published by Elsevier Ltd.

AB Genetic modification of herbaceous plant cell walls to increase biofuels yields is a primary bioenergy research goal. Using two switchgrass populations developed by divergent breeding for ruminant digestibility, the contributions of several wall-related factors to ethanol yields was evaluated. Field grown low lignin plants significantly out yielded high lignin plants for conversion to ethanol by 39.1% and extraction of xylans by 12%. However, across all plants analyzed, greater than 50% of the variation in ethanol yields was attributable to changes in tissue and cell wall architecture, and responses of stem biomass to dilute-acid pretreatment. Although lignin levels were lower in the most efficiently converted genotypes, no apparent correlation were seen in the lignin monomer G/S ratios. Plants with higher ethanol yields were associated with an apparent decrease in the lignification of the cortical sclerenchyma, and a marked decrease in the granularity of the cell walls following dilute-acid pretreatment.

ID SEPTIC-TANK; COMMUNITY; POLLUTION
AB This study for the first time evaluated the soil suitability for onsite wastewater treatment systems (OWTS) within the Alabama Black Belt region and assessed the current status of those OWTS within this area. A local OWTS soil suitability rating system was developed based on current Alabama OWTS regulations and was compared with the existing nationwide Natural Resources Conservation Service soil limitation rating system based on their soil assessment results over the study area. Both rating systems indicate that a large percentage (52%-89%) of land within the study area should not be recommended for conventional OWTS. However, OWTS are widely used and aging in this region. Raster-based OWTS-soil suitability rating system results and US Census-derived demographics were combined in a GIS to prioritize the study area in terms of potential public health threat from OWTS. Although the results lack field verification, two parallel strategies to limit the public health risk from OWTS malfunction are suggested: to extend municipal sewer service to high-risk city fringe areas and to subsidize system retrofit, repair, or replacement of aged OWTS with alternative engineered systems for rural households. Although this study only focused on the Alabama Black Belt area, the presented GIS and demographic methods can be referenced by other regions for similar OWTS assessment purposes.

AB Most forestry property in Andalusia is privately held. One of the most important possibilities for economic development of rural areas is the use of pasture lands (dehesa in Spanish). During the spring-summer season, swine grazing takes advantage of grasses between the trees, and during winter (harsher times), they use Quercus tree fruit. Swine production has a direct economic impact on the rural areas' activities. Wildfires are the most significant disturbance in the Mediterranean ecosystems therefore; it is important to study the potential negative impact of wildfires on the swine resource. The public sector is responsible for the application and valuation of policies or activities creating wealth in forest areas while protecting the environment and preventing greater impacts and damages.

AB The effect of pharmacological dose of cc-tocopherol on heart health was determined in Wistar rats. Animals were randomly assigned to either C (control, n = II) or E (cc-tocopherol, n = II) group. Animals received corn oil (C) or alpha-tocopherol dissolved in corn oil (250 mg alpha-tocopherol/[kg body wt/day]) (E) by gavage for a 7-week period. Rats underwent echocardiogram and were analyzed for cardiomyocyte histology and cardiac cc-tocopherol absorption at the end of the study period. As compared to the C group, alpha-tocopherol-supplemented group showed significantly (p < 0.05) lower body weight (E, 412.8 g vs C, 480.3 g) and total cardiac weight (E, 0.94 g vs C, 1.08 g); cardiomyocyte histological impairment; smaller left ventricle (LV) (LV end-diastolic diameter (E, 7.22 mm vs C, 7.37 mm), lower LV systolic [left ventricle fractional shortening (E, 47.6% vs C, 53.6%) and ejection fraction ratio (E, 85.4 vs C, 89.9)] and diastolic [early peak velocities of diastolic transmitral flow (E, 64.6 cm/sec vs C, 75.1 cm/sec)] function. The alpha-tocopherol uptake in target tissue was confirmed by determination of alpha-tocopherol concentration medians in cardiac tissue (E, 109.91 nmol/kg vs C, 52.09 nmol/kg). The current study indicates that pharmacological dose of alpha-tocopherol supplementation can induce cardiotoxicity in healthy rats.

AB The spruce beetle, Dendroctonus rufipennis (Kirby), is an important mortality agent of native spruces throughout North America. The life-cycle duration of this species varies from 1 to 3 years depending temperature. The univoltine cycle (one generation per year) is thought to maximize outbreak risk and accelerate host mortality in established outbreaks. Prepupal diapause is associated with the semivoltine cycle (one generation per 2 years) and we investigated thermal conditions that result in diapause induction. Preliminary experiments used respirometry in an attempt to distinguish the diapause state of experimental insects but the technique was apparently confounded by low respiration before and during pupation, regardless of diapause status. Therefore, diapause induction was deduced using developmental delays. The observed developmental response was not a "switch", with developmental delay either present or absent, but instead varied continuously. We found that temperatures <15 degrees C from instar Ill through mid-instar IV were associated with developmental delays beyond that expected from cool temperatures. Moreover, the duration of exposure to cool temperatures was important in determining the degree of developmental delay. Small, if any, delays were observed if the cumulative exposure to <15 degrees C was <20 d whereas >40 d cumulative exposure was associated with distinct developmental suppression. Intermediate exposure to cool temperatures resulted in minor developmental delays. We used our results to parameterize a maximum likelihood estimation model of temperature-dependent instar IV developmental rates, including the effect of diapause. This model can be included as part of a spruce beetle phenology model for predicting population dynamics. Published by Elsevier Ltd.

AB Previously, we used heterologous expressed sequence tag (EST) mapping to generate a profile of 4 935 pathogen-response genes of Arabidopsis thaliana. In this work, we performed a computer analysis of this profile, revealing 1 594 non-homologous clustered genes distributed among all A. thaliana chromosomes, whose co-regulation may be related to host responses to pathogens. To supplement computer data, we arbitrarily selected two clusters and analyzed their expression levels in A. thaliana ecotypes Col-0 and C24 during infection with the yellow strain of Cucumber mosaic virus CMV(Y). Ecotype Col-0 is susceptible to CMV(Y), whereas C24 contains the dominant resistance gene RCY1. Upon infection with CMV(Y), all clustered genes were significantly activated in the resistant ecotype C24. In addition, we demonstrated that posttranslational histone modifications associated with trimethylation of histone H3 lysine 27 are most likely involved in regulation of several cluster genes described in this study. Overall, our experiments indicated that pathogen-response genes in the genome of A. thaliana may be clustered and co-regulated.

AB The ends of human chromosomes are protected by DNA-protein complexes termed telomeres, which prevent the chromosomes from fusing with each other and from being recognized as a double-strand break by DNA repair proteins. Due to the incomplete replication of linear chromosomes by DNA polymerase, telomeric DNA shortens with repeated cell divisions until the telomeres reach a critical length, at which point the cells enter senescence. Telomere length is an indicator of biological aging, and dysfunction of telomeres is linked to age-related pathologies like cardiovascular disease, Parkinson disease, Alzheimer disease and cancer. Telomere length has been shown to be positively associated with nutritional status in human and animal studies. Various nutrients influence telomere length potentially through mechanisms that reflect their role in cellular functions including inflammation, oxidative stress, DNA integrity, DNA methylation and activity of telomerase, the enzyme that adds the telomeric repeats to the ends of the newly synthesized DNA.

AB Cold-induced sweetening in potato tubers is a costly problem for the food industry. To systematically identify the proteins associated with this process, we employed a comparative proteomics approach using isobaric, stable isotope coded labels to compare the proteomes of potato tubers after 0 and 5 months of storage at 5 degrees C. We evaluated both high pH reverse phase (hpRP) liquid chromatography (LC) and off-gel electrophoresis (OGE) as first dimension fractionation methods followed by nanoLC-MS/MS, using two high performance mass spectrometry platforms (Q-TOF and Orbitrap). We found that hpRP-LC consistently offered better resolution, reduced expression ratio compression, and a more MS-compatible workflow than OGE and consistently yielded more unique peptide/protein identifications and higher sequence coverage with better quantification. In this study, a total of 4463 potato proteins were identified, of which 46 showed differential expressions during potato tuber cold storage. Several key proteins important in controlling starch-sugar conversion, which leads to cold-induced sweetening, as well as other proteins that are potentially involved in this process, were identified. Our results suggest that the hpRP-RP shotgun approach is a feasible and practical workflow for discovering potential protein candidates in plant proteomic analysis.

AB Oxidative DNA damage plays a role in disease development and the aging process. A prominent participant in orchestrating the repair of oxidative DNA damage, particularly single-strand breaks, is the scaffold protein XRCC1. A series of chronological and biological aging parameters in XRCC1 heterozygous (HZ) mice were examined. HZ and wild-type (WT) C57BL/6 mice exhibit a similar median lifespan of similar to 26 months and a nearly identical maximal life expectancy of similar to 37 months. However, a number of HZ animals (7 of 92) showed a propensity for abdominal organ rupture, which may stem from developmental abnormalities given the prominent role of XRCC1 in endoderm and mesoderm formation. For other end-points evaluated-weight, fat composition, blood chemistries, condition of major organs, tissues and relevant cell types, behavior, brain volume and function, and chromosome and telomere integrity-HZ mice exhibited by-and-large a normal phenotype. Treatment of animals with the alkylating agent azoxymethane resulted in both liver toxicity and an increased incidence of precancerous lesions in the colon of HZ mice. Our study indicates that XRCC1 haploinsufficiency in mammals has little effect on chronological longevity and many key biological markers of aging in the absence of environmental challenges, but may adversely affect normal animal development or increase disease susceptibility to a relevant genotoxic exposure.

AB Objective: The objective was to define the term evidence based nutrition on the basis of expert discussions and scientific evidence.
Methods and procedures: The method used is the established Hohenheim Consensus Conference. The term "Hohenheim Consensus Conference" defines conferences dealing with nutrition-related topics. The major aim of the conference is to review the state of the art of a given topic with experts from different areas (basic science, clinicians, epidemiologists, etc.). Based on eight to 12 questions, the experts discuss short answers and try to come to a consensus. A scientifically based text is formulated that justifies the consensus answer. To discuss the requirements for the scientific substantiation of claims, the 26th Hohenheim Consensus Conference gathered the views of many academic experts in the field of nutritional research and asked these experts to address the various aspects of a claims substantiation process and the possibilities and limitations of the different approaches.
Results: The experts spent a day presenting and discussing their views and arrived at several consensus statements that can serve as guidance for bodies performing claims assessments in the framework of regulatory systems.
Conclusion: The 26th Hohenheim Consensus Conference addresses some general aspects and describes the current scientific status from the point of view of six case studies to illustrate specific areas of scientific interest: carotenoids and vitamin A in relation to age-related macular degeneration, the quality of carbohydrates (as expressed by the glycemic index) in relation to health and well-being, probiotics in relation to intestinal and immune functions, micronutrient intake and maintenance of normal body functions, and food components with antioxidative properties and health benefits.

AB Plant growth promoting rhizobacteria (PGPR) confer disease resistance in many agricultural crops. In the case of Bacillus subtilis (UFLA285) isolated from the cotton producing state of Mato Grosso (Brazil), in addition to inducing foliar and root growth, disease resistance against damping-off caused by Rhizoctonia solani was observed. The aim of this cotton study was to identify gene transcriptional events altered with exposure to the PGPR strain UFLA285 in infected plants. Global gene transcription was profiled using a commercially-available cotton gene chip; cotton plants with and without UFLA285-seed treatment were infected with R. solani 9-days after planting and harvested on day14. Microarray data of stem tissue revealed 247 genes differentially regulated in infected plants, seed treated versus untreated with UFLA285. Transcripts encoding disease resistance proteins via jasmonate/ethylene signaling as well as osmotic regulation via proline synthesis genes were differentially expressed with UFLA285 induction. Consistent with transcriptional regulation, UFLA285 increased plant-proline accumulation and dry weight. This study has identified transcriptional changes in cotton, induced by the beneficial soil bacterium UFLA285 and associated with disease control.

AB Warming and elevated atmospheric CO2 (eCO(2)) can elicit contrasting responses on different SOM pools, thus to understand the effects of combined factors it is necessary to evaluate individual pools. Over two years, we assessed responses to eCO(2) and warming of SOM pools, their susceptibility to decomposition, and whether these responses were mediated by plant inputs in a semi-arid grassland at the PHACE (Prairie Heating and CO2 Enrichment) experiment. We used long-term soil incubations and assessed relationships between plant inputs and the responses of the labile and resistant pools. We found strong and contrasting effects of eCO(2) and warming on the labile C pool. In 2008 labile C was increased by eCO(2) and was positively related to plant biomass. In contrast, in 2007 eCO(2) and warming had interactive effects on the labile C, and the pool size was not related to plant biomass. Effects of warming and eCO(2) in this year were consistent with-treatment effects on soil moisture and temperature and their effects on labile C decomposition. The decomposition rate of the resistant C was positively related to indicators of plant C inputs. Our approach demonstrated that SOM pools in this grassland can have early and contrasting responses to climate change factors. The labile C pool in the mixed-grass prairie was highly responsive to eCO(2) and warming but the factors behind such responses were highly dynamic across years. Results suggest that in this grassland the resistant C pool could be negatively affected by increases in plant-production driven available soil C.

AB Objective: To determine the number of 24 h dietary recalls required to adequately estimate nutrient intake in overweight and obese adults using the US Department of Agriculture's (USDA) automated multiple-pass method (AMPM). In addition, the study quantified sources of variation in dietary intake, such as day of the week, season, sequence of diet interviews (training effect), diet interviewer, body weight and within-and between-subject variances in the intake of selected nutrients.
Design: Adults having a BMI of >= 28 but < 38 kg/m(2) were included in the study. The USDA's AMPM was used to obtain 24 h dietary recalls every 10 d for 6 months. Dietary intake data were analysed to adequately estimate the number of 24 h recalls necessary to assess nutrient intake. Variance component estimates were made by using a mixed-model procedure.
Setting: The greater Washington, DC, metropolitan area.
Subjects: Adults (34 men and 39 women) aged 35-65 years.
Results: Overweight and obese adults completed fourteen 24 h dietary recalls. Utilizing within- and between-subject variances requires 5-10 and 12-15 d of 24 h dietary recalls in men and women, respectively, to estimate energy and macro-nutrient intakes in a 6-month period. Within- and between-subject variances were the major contributors to variance in nutrient intakes. Day of the week, season, sequence, diet interviewer and body weight had little impact on variance.
Conclusions: This information is valuable for researchers planning to conduct studies on free-living individuals that include the collection of dietary intake data.

AB Objective: To investigate genetic and lifestyle factors and their interactions on plasma homocysteine (Hcy) concentrations in the Boston Puerto Rican population.
Design: Cross-sectional study. Plasma concentrations of Hcy, folate, vitamin B(12) and pyridoxal phosphate were measured, and genetic polymorphisms were determined. Data on lifestyle factors were collected in interviews.
Setting: A population survey of health and nutritional measures.
Subjects: A total of 994 Puerto Rican men and women residing in the Boston metropolitan area.
Results: Smoking status was positively associated with plasma Hcy. Genetic polymorphisms MTHFR 677C -> T, FOLH1 1561C -> T, FOLH1 rs647370 and PCFT 928A -> G interacted significantly with smoking for Hcy. MTHFR 1298A -> C (P = 0.040) and PCFT 928A -> G (P = 0.002) displayed significant interactions with alcohol intake in determining plasma Hcy. Subjects with PCFT 928GG genotype had significantly higher plasma Hcy concentrations compared with carriers of the A allele (AA+AG; P = 0.030) among non-drinking subjects. When consuming alcohol, GG subjects had lower plasma Hcy levels compared with AA+AG subjects. Physical activity interacted significantly with MTR 2756A -> G in determining plasma Hcy (P for interaction = 0.002). Smoking interacted with physical activity for plasma Hcy (P for interaction = 0.023).
Conclusions: Smoking and drinking were associated plasma Hcy concentrations. Genetic variants involved in folate metabolism further modify the effects of lifestyle on plasma Hcy.

AB Objective: To compare the school lunch consumption of Texas middle-school students with the 2009 Institute of Medicine's (IOM) school meal report recommendations. These new lunch menu patterns increase fruit to one serving and vegetables to two servings, with 50% wholegrain food.
Design: Lunch food records were collected from middle-school students from four schools in south-east Texas in the spring of 2008, and entered into the Nutrition Data System for Research software. Average intake was calculated for those consuming meals according to the National School Lunch Program (NSLP; n 5414) and for those consuming lunch from other sources (n 239). The percentage of students selecting each food group was calculated.
Setting: Middle schools in south-east Texas.
Subjects: Middle-school students in south-east Texas.
Results: Students consuming NSLP meals reported consuming almost 1/2 serving of fruit, 3/4 serving of vegetables, 8 oz of milk and 1/3 serving of whole grains at lunch. Non-NSLP consumers reported almost no intake of fruit, vegetables or milk, and consumed 1/4 serving of whole grains at lunch. Among NSLP consumers, about 40% selected and consumed a fruit serving. About two-thirds of students selected a vegetable, consuming about 67%. Less than 4% selected a dark green or orange vegetable.
Conclusions: Students' lunch intake did not meet the new IOM recommendations. Few students selected dark green or orange vegetables, and only 40% selected fruit. Whole grains consumption was low. Interventions with all stakeholders will be necessary to improve students' food and beverage selections overall when school meal patterns are revised.

AB Knowledge of the pools and fluxes of C and N soil components is required to interpret ecosystem functioning and improve biogeochemical models. Two former grassland soils, where wheat or corn are currently growing, were studied by kinetic analysis of microbial biomass C and N changes, C and N mineralization rates, acid hydrolysis, and pyrolysis. Nearly twice as much C as N was mineralized during incubation. Modeling of changes during incubation demonstrated that two-pool first-order kinetics effectively described losses of microbial biomass C and N and concurrent N mineralization. Loss of microbial biomass N during incubation accounted for a significant portion of the N mineralized. Microbial biomass N content and soil N mineralization rates were strongly affected by soil type and soil management. Nitrification, but not N mineralization, was inhibited during the latter stages of incubation in one of the soils. We believe nitrifier populations had dropped below effective levels. Nonacid hydrolysable C was increased in both amount and mean residence time by cultivation and incubation. Hydrolysis removed a larger amount of N than incubation. Data after pyrolysis of soils, in argon at 550 degrees C, closely reflected results for both C and N found after cultivation and incubation. This technique should be further investigated to identify the recalcitrant forms of C and N in soils. The dynamics of soil C and soil N, although related, are not identical; thus, management can be targeted to soil C or N cycling in ecosystem functioning or to soil organic matter dynamics in global change.

First published June 21, 2011; doi:10.1152/ajpendo.00709.2010.-Chronic inflammation is associated with obesity and insulin resistance; however, the underlying mechanisms are not fully understood. Pattern recognition receptors Toll-like receptors and nucleotide-oligomerization domain-containing proteins play critical roles in innate immune response. Here, we report that activation of nucleotide binding oligomerization domain-containing protein-1 (NOD1) in adipocytes induces proinflammatory response and impairs insulin signaling and insulin-induced glucose uptake. NOD1 and NOD2 mRNA are markedly increased in differentiated murine 3T3-L1 adipocytes and human primary adipocyte culture upon adipocyte conversion. Moreover, NOD1 mRNA is markedly increased only in the fat tissues in diet-induced obese mice, but not in genetically obese ob/ob mice. Stimulation of NOD1 with a synthetic ligand Tri-DAP induces proinflammatory chemokine MCP-1, RANTES, and cytokine TNF-alpha and MIP-2 (human IL-8 homolog) and IL-6 mRNA expression in 3T3-L1 adipocytes in a time- and dose-dependent manner. Similar proinflammatory profiles are observed in human primary adipocyte culture stimulated with Tri-DAP. Furthermore, NOD1 activation suppresses insulin signaling, as revealed by attenuated tyrosine phosphorylation and increased inhibitory serine phosphorylation, of IRS-1 and attenuated phosphorylation of Akt and downstream target GSK3 alpha/3 beta, resulting in decreased insulin-induced glucose uptake in 3T3-L1 adipocytes. Together, our results suggest that NOD1 may play an important role in adipose inflammation and insulin resistance in diet-induced obesity.

AB A sensitive direct enzyme-linked immunosorbent assay (ELISA) for the specific detection of 2,2', 4,4'-tetrabromodiphenyl ether (BDE-47) in environmental samples was developed. A hapten mimicking BDE-47 was synthesized by introducing a butyric acid spacer into 5-hydroxy-BDE-47 and coupled to keyhole limpet hemocyanin to form an immunogen for the production of monoclonal antibodies (Mabs) against BDE-47. The most sensitive direct ELISA was formatted with a Mab, designated as 4F2, in combination with 5-(2,4-dibromophenoxy) pentanoic acid peroxidase as a tracer. The inhibition half-maximum concentrations and limit of detection of BDE-47 in phosphate buffered saline with 25% DMSO were 1.4 +/- 0.05 and 0.1 ng mL(-1), respectively. Cross-reactivity values of the ELISA with the tested BDE congeners and metabolites were <= 5.8%. This assay was used to determine BDE-47 in soil, sediment and house dust samples after ultrasonic extraction, simple cleanup and concentration steps. The average recoveries, repeatabilities (intraday extractions and analyses), and intra-laboratory reproducibilities (interday extractions and analyses) were in a range of 92-126%, 8-19% and 9-25%, respectively. Applied to 44 real samples, the results of this assay displayed a statistically significant correlation with those of a gas chromatography-mass spectrometry method (R(2)=0.79-0.85), indicating this ELISA is a suitable tool for environmental analyses of BDE-47.

AB We are interested in identifying targets that may be used to develop new control products for the common housefly, Musca domestica, a vector of disease for many vertebrates. One such target, ornithine decarboxylase (ODC), is an embryonic enzyme involved in the regulation of polyamines and is a critical enzyme during M. domestica development. In this study, the cDNA for ODC from M. domestica was cloned, sequenced, and characterized. The full-length cDNA was 1,337-bp, consistent with a single band of approximately 1.35 kb obtained by northern analysis. The open-reading frame contains 1,191 bp, yielding a deduced polypeptide of 396 amino acid residues with a predicted mass of 44,618 Da. The deduced M. domestica ODC protein was homologous to other ODC proteins. mRNA expression profiles analyzed by real-time PCR indicated that the ODC transcript is temporally regulated throughout embryogenesis. Sequence data and Southern blot analysis suggests that there were likely only one or two closely linked copies of the M. domestica ODC gene. (C) 2011 Wiley Periodicals, Inc.

AB Enterotoxigenic Escherichia coli (ETEC) strains expressing K88 (F4) or F18 fimbriae and heat-labile (LT) and/or heat-stable (ST) toxins are the major cause of diarrhea in young pigs. Effective vaccines inducing antiadhesin (anti-K88 and anti-F18) and antitoxin (anti-LT and anti-ST) immunity would provide broad protection to young pigs against ETEC. In this study, we genetically fused nucleotides coding for peptides from K88ac major subunit FaeG, F18 minor subunit FedF, and LT toxoid (LT192) A2 and B subunits for a tripartite adhesin-adhesin-toxoid fusion (FaeG-FedF-LT(192)A2:B). This fusion was used for immunizations in mice and pigs to assess the induction of antiadhesin and antitoxin antibodies. In addition, protection by the elicited antiadhesin and antitoxin antibodies against a porcine ETEC strain was evaluated in a gnotobiotic piglet challenge model. The data showed that this FaeG-FedF-LT(192)A2: B fusion elicited anti-K88, anti-F18, and anti-LT antibodies in immunized mice and pigs. In addition, the anti-porcine antibodies elicited neutralized cholera toxin and inhibited adherence against both K88 and F18 fimbriae. Moreover, immunized piglets were protected when challenged with ETEC strain 30302 (K88ac/LT/STb) and did not develop clinical disease. In contrast, all control nonvaccinated piglets developed severe diarrhea and dehydration after being challenged with the same ETEC strain. This study clearly demonstrated that this FaeG-FedF-LT(192)A2: B fusion antigen elicited antibodies that neutralized LT toxin and inhibited the adherence of K88 and F18 fimbrial E. coli strains and that this fusion could serve as an antigen for vaccines against porcine ETEC diarrhea. In addition, the adhesin-toxoid fusion approach used in this study may provide important information for developing effective vaccines against human ETEC diarrhea.

AB Bighorn sheep (BHS) are more susceptible than domestic sheep (DS) to Mannheimia haemolytica pneumonia. Although both species carry M. haemolytica as a commensal bacterium in the nasopharynx, DS carry mostly leukotoxin (Lkt)-positive strains while BHS carry Lkt-negative strains. Consequently, antibodies to surface antigens and Lkt are present at much higher titers in DS than in BHS. The objective of this study was to determine whether repeated immunization of BHS with multivalent Mannheimia-Bibersteinia vaccine will protect them upon M. haemolytica challenge. Four BHS were vaccinated with a culture supernatant vaccine prepared from M. haemolytica serotypes A1 and A2 and Bibersteinia trehalosi serotype T10 on days 0, 21, 35, 49, and 77. Four other BHS were used as nonvaccinated controls. On the day of challenge, 12 days after the last immunization, the mean serum titers of Lkt-neutralizing antibodies and antibodies to surface antigens against M. haemolytica were 1: 160 and 1: 4,000, respectively. Following intranasal challenge with M. haemolytica A2 (1 x 105 CFU), all four control BHS died within 48 h. Necropsy revealed acute fibrinonecrotic pneumonia characteristic of M. haemolytica infection. None of the vaccinated BHS died during the 8 weeks postchallenge observation period. Radiography at 3 weeks postchallenge revealed no lung lesions in two vaccinated BHS and mild lesions in the other two, which resolved by 8 weeks postchallenge. These results indicate that if BHS can be induced to develop high titers of Lkt-neutralizing antibodies and antibodies to surface antigens, they are likely to survive M. haemolytica challenge which is likely to reduce the BHS population decline due to pneumonia.

AB Rice cultivated on arsenic (As) contaminated-soils will accumulate variable grain-As concentrations, as impacted by varietal differences, soil variables, and crop management. A field-scale experiment was conducted to study the impact of intermittent and continuous flooding on As speciation and microbial populations in rice rhizosphere compartments of soils that were either historically amended with As pesticide or unamended with As. Rhizosphere-soil, root-plaque, pore-water and grain As were quantified and speciated, and microbial populations in rhizosphere soil and root-plaque were characterized. Total-As concentrations in rhizosphere and grain were significantly lower in intermittently flooded compared to the continuously flooded plots (86% lower in pore-water, 55% lower in root-plaque and 41% lower in grain samples). iAs(V), iAs(III), and DMAs(V) were the predominant As species detected in rhizosphere-soil and root-plaque, pore-water and grain samples, respectively. Relative proportions of Archaea and iron-reducing bacteria (FeRB) were higher in rhizosphere soil compared to root-plaque. In rhizosphere soil, the relative abundance of FeRB was lower in intermittently flooded compared to continuously flooded plots, but there were no differences between root-plaque samples. This study has demonstrated that reductions in dissolved As concentrations in the rhizosphere and subsequent decreases in grain-As concentration can be attained through water management.

AB Advances in fungal biosystematics and molecular genetics have clarified relationships among the wood-decay fungi and are providing new tools for their detection and identification. Species complexes of forest pathogens, including those within Heterobasidion, Armillaria, Laetiporus, and Phellinus, are being resolved. The ability to isolate fungal DNA directly from wood without in intermediate culturing step will greatly facilitate sampling and disease detection and has applications in forest disease management, hazard tree assessment, invasive species detection, and carbon cycling, sequestration and climate change research. Recent changes in fungal nomenclature and their application to forest pathology are discussed.

AB Aims: The germination-arrest factor (GAF) produced by Pseudomonas fluorescens WH6, and identified as 4-formylaminooxyvinylglycine, specifically inhibits the germination of a wide range of grassy weeds. This study was undertaken to determine whether GAF has antimicrobial activity in addition to its inhibitory effects on grass seed germination.
Methods and Results: Culture filtrate from Ps. fluorescens WH6 had little or no effect on 17 species of bacteria grown in Petri dish lawns, but the in vitro growth of Erwinia amylovora, the causal agent of the disease of orchard crops known as fire blight, was strongly inhibited by the filtrate. The anti-Erwinia activity of WH6 culture filtrate was shown to be due to its GAF content, and a commercially available oxyvinylglycine, 4-aminoethoxyvinylglycine (AVG), exhibited anti-Erwinia activity similar to that of GAF. The effects of GAF on Erwinia were reversed by particular amino acids.
Conclusions: The biological properties of GAF include a rather specific antimicrobial activity against Erw. amylovora. This may be a general property of oxyvinylglycines as AVG exhibited similar activity. The ability of particular amino acids to reverse GAF inhibition is consistent with a potential effect of this compound on the activity of aminotransferases.
Significance and Impact of the Study: The results presented here demonstrate a novel antimicrobial activity of oxyvinylglycines and suggest that GAF and/or GAF-producing bacteria may have potential for the control of fire blight.

AB The mechanisms leading to weight loss in patients with chronic obstructive pulmonary disease (COPD) are poorly understood. Changes in protein metabolism and systemic inflammation may contribute to increased resting energy expenditure (REE) in COPD, leading to an energy imbalance and loss of fat and fat-free mass. The objective of this study was to determine first whether REE was increased in patients with COPD and, second, whether this was associated with increased protein turnover and/or systemic inflammation. Resting energy expenditure was determined using indirect calorimetry in 14 stable outpatients with severe COPD (7 with low and 7 with preserved body mass indices) and 7 healthy controls. Endogenous leucine flux, leucine oxidation, and nonoxidative disposal, indices of whole-body protein breakdown, catabolism, and synthesis, were measured using intravenous infusions of (13)C-bicarbonate and 1-(13)C-leucine. Total body water, from which fat-free mass and fat mass were calculated, was determined using an intravenous bolus of deuterated water. Plasma markers of systemic inflammation were also measured. As a group, subjects with COPD had increased REE adjusted for fat-free mass (P < .001) and faster rates of endogenous leucine flux (P = .006) and nonoxidative leucine disposal (P =.002) compared with controls. There was a significant correlation between REE and both endogenous leucine flux (P = .02) and nonoxidative leucine disposal (P = .008). Plasma concentrations of the inflammatory markers C-reactive protein and interleukin-6 were not different between COPD subjects and controls. Increased rates of protein turnover are associated with increased REE and loss of fat-free mass in COPD. (C) 2011 Elsevier Inc. All rights reserved.

AB Data from cellular systems and transgenic animal models suggest a role of apolipoprotein (apo) A-II in the regulation of very low-density lipoprotein (VLDL) metabolism. However, the precise mechanism whereby apoA-II regulates VLDL metabolism remains to be elucidated in humans. In this study, we examined the associations between the kinetics of high-density lipoprotein (HDL)-apoA-II and VLDL-apoB-100 kinetics, and plasma adiponectin concentrations. The kinetics of HDL-apoA-II and VLDL-apoB-100 were measured in 37 nonobese men using stable isotope techniques. Plasma adiponectin concentration was measured using immunoassays. Total plasma apoA-II concentration was positively associated with HDL-apoA-II production rate (PR) (r = 0.734, P < .01); both were positively associated with plasma triglyceride concentration (r = 0.360 and 0.369, respectively) and VLDL-apoB-100 PR (r = 0.406 and 0.427, respectively), and inversely associated with plasma adiponectin concentration (r = -0.449 and -0.375, respectively). Plasma adiponectin was inversely associated with plasma triglyceride concentration (r = -0.327), VLDL-apoB-100 concentration (r = -0.337), and VLDL-apoB-100 PR (r = -0.373). In multiple regression models including waist circumference and plasma insulin, plasma adiponectin concentration was an independent determinant of total plasma apoA-II concentration (beta-coefficient = -0.508, P = .001) and HDL-apoA-II PR (beta-coefficient = -0.374, P = .03). Conversely, total plasma apoA-II concentration (beta-coefficient = 0.348, P = .047) and HDL-apoA-II PR (beta-coefficient = -0.350, P = .035) were both independent determinants of VLDL-apoB-100 PR. However, these associations were not independent of plasma adiponectin. Variation in HDL apoA-II production, and hence total plasma apoA-II concentration, may exert a major effect on VLDL-apoB-100 production. Plasma adiponectin may also contribute to the variation in VLDL-apoB-100 production partly by regulating apoA-II transport. (C) 2011 Elsevier Inc. All rights reserved.

More recently, experimental and epidemiological data have emerged to suggest that maternal intake of these nutrients during gestation may also have an impact on the risk of cancer in offspring later in life. Given the plasticity of DNA methylation in the developing embryo and the established role of one-carbon metabolism in supporting biological methylation reactions, it is plausible that alterations in maternal one-carbon nutrient availability might induce subtle epigenetic changes in the developing embryo and fetus that persist into later life, altering the risk of tumorigenesis throughout the lifespan. This review summarizes the current literature on maternal one-carbon nutrient intake and offspring cancer risk, with an emphasis on cancers of the colon and breast, and discusses specific epigenetic modifications that may play a role in their pathogenesis.

AB Verticillium dahliae causes severe wilt and recurring losses in numerous agricultural and ornamental hosts worldwide. Two virulence phenotypes (races) have been identified based on the Ve resistance gene and its homologs but their distribution and evolutionary history are unknown. Sequence analyses of the intergenic spacer of the ribosomal DNA and amplified fragment length polymorphism markers suggested an absence of correlation between genotypic diversity and virulence phenotypes. Additionally, both race 1 and 2 phenotypes were isolated in various geographic regions and hosts. Sustained levels of migration of both virulence phenotypes among various geographic regions were evident, and the study also suggested that both virulence phenotypes infect a variety of hosts, regardless of the availability of resistant cultivars. Given the high genotypic diversity observed in V dahliae, more than the two known virulence phenotypes may be present in nature but not yet identified because of the current lack of sources of resistance other than the Ve gene and its homologs. The inclusion of various genotypes exhibiting the same virulence phenotype may greatly improve the long-term effectiveness of resistance to race 2 of V dahliae regardless of the host. This study also confirms the transcontinental gene flow and high genotypic diversity of V dahliae affecting lettuce in coastal California regardless of the molecular markers employed.

AB We hypothesized that Armillaria gallica, which is abundant in oak-dominated forests, is more successful at oxidizing and metabolizing polyphenols than A. calvescens, which is mostly restricted to maple-dominated forests. Isolates were challenged with up to seven concentrations of tannic acid (TA), gallic acid (GA), and black oak root bark extracts (RBE). Six concentrations of glucose and ethanol were also tested to determine the influence of available carbon on growth. Colony area and biomass values were analyzed using a GLM and Tukey's HSD test. When challenged with 0.12% concentrations of TA, GA, and RBE, A. gallica produced a significantly larger biomass in all treatments and larger colony areas in four of the five treatments compared to control values. A. gallica also produced a significantly larger number of rhizomorphs than A. calvescens on RBE medium. In contrast, A. calvescens generated significantly larger biomass over control treatments only when RBE was added, and values were substantially less compared to A. gallica. Growth of both species was significantly greater when ethanol was added, especially on GA medium, while glucose had little effect. Results from this study suggest that A. gallica is better at oxidizing and metabolizing polyphenols than A. calvescens.

AB Potato virus Y (PVY) is a reemerging problem in potato production in North America. Although the "ordinary" strain, PVYO, is still the dominant isolate in U.S. seed potatoes, the recombinant strain of the virus PVYN-Wi (= PVYN:O) has become widespread. An increase in the prevalence of a PVY strain could be due to differences in the efficiency of transmission by aphid vectors. The transmission efficiency by a clone of Myzus persicae was determined for five isolates each of PVYO and PVYN-Wi. An aphid transmission assay was developed based on the use of potato seedlings from true potato seed, allowing for greater control of plant age and growth stage. No apparent differences in transmission by M. persicae were observed. Single isolates of PVYO and PVYN-Wi were tested for their ability to be transmitted from potato to potato by five aphid species: Aphis glycines, A. gossypii, A. nasturtii, M. persicae, and Rhopalosiphum padi. Both PVY isolates showed a similar transmission phenotype in being transmitted efficiently by M. persicae but very poorly or not at all by A. glycines, A. gossypii, and R. padi. The aphid A. nasturtii transmitted both isolates with an intermediate level of efficiency. The data do not support a model for a differential aphid transmissibility being responsible for the increase in the prevalence of PVYN-Wi.

TI Successful Prediction of Genetic Richness at Wild Potato Collection

SO AMERICAN JOURNAL OF POTATO RESEARCH

DT Article
DE Stoloniferum; Longipedicellata
AB Collecting germplasm from even a fraction of the potential geographic range of wild potato species requires substantial time, money, and effort, so efficiency could be increased if spots particularly rich in unique alleles could be predicted and prioritized. A previous experiment that used AFLP markers to compare "remote" versus "easy" collection sites for Solanum stoloniferum, (previously S. fendleri) within three mountain ranges identified the Santa Catalina Mountains (CAT) of SE Arizona as making a particularly large contribution of unique alleles, despite existing CAT collections being few and all close to roads. This situation motivated a collecting expedition in September 2009 to more thoroughly collect CAT. That expedition resulted in samples of 16 populations, most from new sites never previously described or collected. An analysis was done with 871 AFLP loci, comparing populations from the same three mountain ranges and including the 2009 CAT collections. Results confirmed the prediction of unique allele density of certain location categories within mountain ranges. The new CAT collections captured three times as many unique alleles as contained in the previous collections from that location, and 24 of these were new (unique) among all mountain ranges. One particular new collection, PI 658180, accounted for 46% of the new unique alleles collected in CAT. This study demonstrates the power of DNA markers to empirically identify locations with genetic richness, guiding the most efficient allocation of resources for collecting, preservation, and evaluation of germplasm.

AB Zebra chip (ZC), an emerging and serious disease of potato has caused millions of dollars in losses to the potato industry in the United States, Mexico, Central America, and New Zealand. The disease has recently been associated with a previously undescribed species of liberibacter tentatively named "Candidatus Liberibacter solanacearum" transmitted to potato by the potato psyllid, Bactericera cockerelli (ulc). At present, applications of insecticides targeted against the potato psyllid are the only means to manage ZC. Given the low psyllid density and short inoculation access period required to induce the disease, insecticides may not act fast enough to prevent transmission of liberibacter to potato by the psyllid and development of ZC. Identification and development of ZC-resistant or tolerant varieties may offer the most efficient and sustainable way to manage this potato disease. Susceptibility of selected potato varieties to ZC was evaluated under controlled field cage conditions in 2009 and 2010 in WA by inoculating potato plants with "Ca. L. solanacearum" using infective potato psyllids and monitoring them for ZC symptom development. All potato varieties evaluated in both years of the study were determined to be very susceptible to the disease, with almost 100% of the inoculated plants developing severe ZC foliar and tuber symptoms. Potato yield in all tested varieties was significantly affected by ZC, with yield losses ranging from 49.9% to 87. 2%. Information from this research suggests that there is an urgent need to develop new potato varieties that are resistant or tolerant to this damaging potato disease.

AB The complexity of fecal microbial communities and overlap among human and other animal sources have made it difficult to identify source-specific fecal indicator bacteria. However, the advent of next-generation sequencing technologies now provides increased sequencing power to resolve microbial community composition within and among environments. These data can be mined for information on source-specific phylotypes and/or assemblages of phylotypes (i.e., microbial signatures). We report the development of a new genetic marker for human fecal contamination identified through microbial pyrotag sequence analysis of the V6 region of the 16S rRNA gene. Sequence analysis of 37 sewage samples and comparison with database sequences revealed a human-associated phylotype within the Lachnospiraceae family, which was closely related to the genus Blautia. This phylotype, termed Lachno2, was on average the second most abundant fecal bacterial phylotype in sewage influent samples from Milwaukee, WI. We developed a quantitative PCR (qPCR) assay for Lachno2 and used it along with the qPCR-based assays for human Bacteroidales (based on the HF183 genetic marker), total Bacteroidales spp., and enterococci and the conventional Escherichia coli and enterococci plate count assays to examine the prevalence of fecal and human fecal pollution in Milwaukee's harbor. Both the conventional fecal indicators and the human-associated indicators revealed chronic fecal pollution in the harbor, with significant increases following heavy rain events and combined sewer overflows. The two human-associated genetic marker abundances were tightly correlated in the harbor, a strong indication they target the same source (i.e., human sewage). Human adenoviruses were routinely detected under all conditions in the harbor, and the probability of their occurrence increased by 154% for every 10-fold increase in the human indicator concentration. Both Lachno2 and human Bacteroidales increased specificity to detect sewage compared to general indicators, and the relationship to a human pathogen group suggests that the use of these alternative indicators will improve assessments for human health risks in urban waters.

AB In the family Enterobacteriaceae, plasmids have been classified according to 27 incompatibility (Inc) or replicon types that are based on the inability of different plasmids with the same replication mechanism to coexist in the same cell. Certain replicon types such as IncA/C are associated with multidrug resistance (MDR). We developed a microarray that contains 286 unique 70-mer oligonucleotide probes based on sequences from five IncA/C plasmids: pYR1 (Yersinia ruckeri), pPIP1202 (Yersinia pestis), pP99-018 (Photobacterium damselae), pSN254 (Salmonella enterica serovar Newport), and pP91278 (Photobacterium damselae). DNA from 59 Salmonella enterica isolates was hybridized to the microarray and analyzed for the presence or absence of genes. These isolates represented 17 serovars from 14 different animal hosts and from different geographical regions in the United States. Qualitative cluster analysis was performed using CLUSTER 3.0 to group microarray hybridization results. We found that IncA/C plasmids occurred in two lineages distinguished by a major insertion-deletion (indel) region that contains genes encoding mostly hypothetical proteins. The most variable genes were represented by transposon-associated genes as well as four antimicrobial resistance genes (aphA, merP, merA, and aadA). Sixteen mercury resistance genes were identified and highly conserved, suggesting that mercury ion-related exposure is a stronger pressure than anticipated. We used these data to construct a core IncA/C genome and an accessory genome. The results of our studies suggest that the transfer of antimicrobial resistance determinants by transfer of IncA/C plasmids is somewhat less common than exchange within the plasmids orchestrated by transposable elements, such as transposons, integrating and conjugative elements (ICEs), and insertion sequence common regions (ISCRs), and thus pose less opportunity for exchange of antimicrobial resistance.

AB Background At present, B cell epitopes involved in food allergy to wheat are known only for a few allergens and a few categories of patients.
Objective To characterize the epitopes of different wheat kernel allergens: alpha-, gamma, omega 2, and omega 5-gliadin, a low-molecular-weight (LMW) glutenin subunit, and a lipid transfer protein (LTP1) recognized by allergic patients and by sensitized mice and provide further understanding of the role of structure in determining allergic response.
Methods Sera were obtained from 39 patients suffering from food allergy to wheat. BALB/c mice were sensitized to gliadins or LTP1 by intraperitoneal immunizations. Continuous epitopes bound by IgE were delineated by the Pepscan technique. The response to reduced, alkylated LTP1 was compared with that of the native form to evaluate the importance of protein folding on IgE reactivity.
Results Few continuous epitopes of LTP1 reacted with IgE from allergic patients and mice, but one of them was common to several patients and sensitized mice. The unfolded protein was not recognized by either patient or mouse IgE, emphasizing the major role of LTP1 folding and discontinuous epitopes in IgE-binding. In contrast, many continuous epitopes were detected by patient and mouse IgE especially for an omega 5-gliadin, which is an unstructured protein, and to a lesser extent, for the other gliadins and a LMW-glutenin subunit.
Conclusion and Clinical Relevance The conformation of LTP1 appeared to have a strong impact on the type of IgE-binding epitopes elicited by this protein in both man and mouse. The responses in mice sensitized to gliadins or LTP1 were sufficiently comparable with the human response in terms of IgE-binding epitopes to provide support for the use of the mouse model in further investigations.

AB Salmonella can live undetected in the gut of food animals and be transmitted to humans. Animal diets can impact intestinal populations of foodborne pathogens, including Salmonella spp. Orange juice production results in a waste product, orange peel and orange pulp, which has a high nutritive value and is often included in cattle diets as a least-cost ration ingredient. Here we show that the inclusion of orange peel products reduced Salmonella Typhimurium populations in the gut of experimentally inoculated sheep. Sheep (n = 24) were fed a cracked corn grain-based high grain diet that was supplemented with a 50%/50% (dry matter [DM], w/w) mixture of dried orange pellet and fresh orange peel to achieve a final concentration (DM, basis) of 0%, 10%, or 20% orange product (OP) for 10 days before inoculation with Salmonella Typhimurium. Sheep were experimentally inoculated with 10 10 colony forming units Salmonella Typhimurium, and fecal samples were collected every 24 h after inoculation. Sheep were humanely euthanized at 96 h after oral Salmonella inoculation. Populations of inoculated Salmonella Typhimurium were numerically reduced by OP treatment throughout the gastrointestinal tract, and this reduction only reached significant levels in the cecum (p < 0.05) of sheep fed 10% OP diets. Apparent palatability issues decreased the consumption of OP in sheep fed 20% OP to intake levels below that of 10% OP (approximately 7% dry matter intake [DMI]/d feed refusal), thereby reducing the potential effects of OP feeding at this higher level. Our results demonstrate that orange peel and pellets are environmentally friendly and low-cost products that can be used as a pre-harvest intervention as part of an integrated pathogen reduction scheme.

AB Pulsed electric field (PEF) treatments, a nonthermal process, have been reported to injure and inactivate bacteria in liquid foods. However, the effect of this treatment on bacterial cell surface charge and hydrophobicity has not been investigated. Apple juice (pH 3.8) purchased from a wholesale distributor was inoculated with cocktail of Escherichia coli O157:H7 at 7.4 log CFU/mL, processed with a PEF at a field strength of 18.4 kV/cm and 32.2 kV/cm at 25 degrees C, 35 degrees C, and 45 degrees C with a treatment time of 160 mu s and a flow rate of 120 mL/min. Bacterial cell surface charge and hydrophobicity of untreated and PEF-treated E. coli O157: H7 were determined immediately and after storage at 5 degrees C and 23 degrees C using hydrophobic and electrostatic interaction chromatography. Similarly, the populations surviving the PEF treatments including injured cells were determined by plating 0.1 mL of the sample on sorbitol MacConkey agar and tryptic soy agar (TSA) plates. The surviving populations of E. coli cells after PEF treatment varied depending on field strength and treatment temperature used. Percent injury in the surviving populations was high immediately after PEF treatment and varied among treatment temperatures. Cell surface charge of E. coli bacteria before PEF treatment averaged 32.10 +/- 8.12. PEF treatments at 25 degrees C, 35 degrees C, and 45 degrees C reduced the above surface charge to 26.34 +/- 1.24, 14.24 +/- 3.30, and 6.72 +/- 2.82, respectively. Similarly, the surface hydrophobicity of untreated E. coli cells at 0.194 +/- 0.034 was increased to an average of 0.268 +/- 0.022, 0.320 +/- 0.124, and 0.586 +/- 0.123 after PEF treatments at 25 degrees C, 35 degrees C, and 45 degrees C, respectively. The results of this study indicate that PEF treatment affects the outer cell envelope of E. coli bacteria as evidenced by the changes in surface hydrophobicity and cell surface charge leading to injury and subsequent inactivation of the cells.

AB Three mutations in the Pectinophora gossypiella cadherin gene PgCad1 are linked with resistance to Bacillus thuringiensis (Bt) toxin Cry1Ac. Here we show that the r3 mutation entails recent insertion into PgCad1 of an active chicken repeat (CR1) retrotransposon, designated CR1-1_Pg. Unlike most other CR1 elements, CR1-1_Pg is intact, transcribed by a flanking promoter, contains target site duplications and has a relatively low number of copies. Examination of transcripts from the PgCad1 locus revealed that CR1-1_Pg disrupts both the cadherin protein and a long noncoding RNA of unknown function. Together with previously reported data, these findings show that transposable elements disrupt eight of 12 cadherin alleles linked with resistance to Cry1Ac in three lepidopteran species, indicating that the cadherin locus is a common target for disruption by transposable elements.

AB Crustaceans are a globally-distributed faunal group, found across all habitats from the equator to the poles. They are an ideal focal assemblage for assessment of the impacts of climatic change and anthropogenic disturbance on nonmodel systems, such as how sea currents influence the movements of zooplankton communities in the open ocean, or how ecosystem processes affect phytoplanktonic species with restricted geographic distributions across a cluster of island lakes that could be a new model system for studies of speciation. This symposium introduced early-career researchers working in the fields of phylogeography, ecogenomics, fisheries management, and ecosystem processes with the aim of highlighting the different genetic and ecological approaches to the study of population dynamics of freshwater, estuarine, and marine crustacean species.

AB The diversity of regulatory systems encoded by bacteria provides an indication of the variety of stresses and interactions that these organisms encounter in nature. We have been investigating how the plant pathogen Pseudomonas syringae pv. tomato DC3000 responds to iron limitation and have focused on the iron starvation (IS) sigma factors to identify regulon members and to explore the mechanistic details of genetic control for this class of regulators. In the study described in this report, we used chromatin immunoprecipitation paired with high-throughput sequencing (ChIP-Seq) to screen the genome for locations associated with binding of the P. syringae IS sigma factor PSPTO_1203. We used multiple methods to demonstrate differential regulation of two genes identified in the ChIP-Seq screen and characterize the promoter elements that facilitate PSPTO_1203-dependent regulation. The genes regulated by PSPTO_1203 encode a TonB-dependent transducer (PSPTO_1206) and a cytoplasmic membrane protein (PSPTO_2145), which is located in the P. syringae pyoverdine cluster. Additionally, we identified siderophores that induce the activity of PSPTO_1203 and used this information to investigate the functional components of the signal transduction cascade.

AB Salmonella enterica serovar Typhimurium can utilize molecular hydrogen for growth and amino acid transport during anaerobic growth. Via microarray we identified H(2) gas-affected gene expression changes in Salmonella. The addition of H(2) caused altered expression of 597 genes, of which 176 genes were upregulated and 421 were downregulated. The significantly H(2)-upregulated genes include those that encode proteins involved in the transport of iron, manganese, amino acids, nucleosides, and sugars. Genes encoding isocitrate lyase (aceA) and malate synthase (aceB), both involved in the carbon conserving glyoxylate pathway, and genes encoding the enzymes of the D-glucarate and D-glycerate pathways (gudT, gudD, garR, garL, garK) are significantly upregulated by H(2). Cells grown with H(2) showed markedly increased AceA enzyme activity compared to cells without H(2). Mutant strains with deletion of either aceA or aceB had reduced H(2)-dependent growth rates. Genes encoding the glutamine-specific transporters (glnH, glnP, glnQ) were upregulated by H(2), and cells grown with H(2) showed increased [(14)C] glutamine uptake. Similarly, the mannose uptake system genes (manX, manY) were upregulated by H(2), and cells grown with H(2) showed about 2.0-fold-increased [(14)C] D-mannose uptake compared to the cells grown without H(2). Hydrogen stimulates the expression of genes involved in nutrient and carbon acquisition and carbon-conserving pathways, linking carbon and energy metabolism to sustain H(2)-dependent growth.

AB Physiological effects of thyroid hormones are mediated primarily by binding of triiodothyronine to specific nuclear receptors. Organ-specific changes in production of triiodothyronine from its prohormone, thyroxine, have been hypothesized to target the action of thyroid hormones on the mammary gland and play a role in mediating or augmenting a galactopoietic response to bovine somatotropin (bST). Additionally, tissue responsiveness to thyroid hormones may be altered by changes in the number or affinity of nuclear receptors for thyroid hormones. In the present study, effects of bST and bovine growth hormone-releasing factor (bGRF) on thyroid hormone receptors in liver and mammary gland were studied. Lactating Holstein cows received continuous infusions of bST or bGRF for 63 d or served as uninfused controls. Nuclei were isolated from harvested mammary and liver tissues and incubated with [(125)I]-triiodothyronine. Treatments did not alter the capacity or affinity of specific binding sites for triiodothyronine in liver or mammary nuclei. Evaluation of transcript abundance for thyroid hormone receptors showed that isoforms of thyroid hormone receptor or retinoid receptor (which may influence thyroid receptor action) expressed in the mammary gland were not altered by bST or bGRF treatment. Data do not support the hypothesis that administration of bST or bGRF alters sensitivity of mammary tissue by changing expression of thyroid hormone receptors.

AB A lactating cow trial was conducted to study the effects of dietary addition of oregano leaf material (Origanum vulgare L.; OV; 0, control vs. 500 g/d) on ruminal fermentation, methane production, total tract digestibility, manure gas emissions, N metabolism, organoleptic characteristics of milk, and dairy cow performance. Eight primiparous and multiparous Holstein cows (6 of which were ruminally cannulated) were used in a crossover design trial with two 21-d periods. Cows were fed once daily. The OV material was top-dressed and mixed with a, portion of the total mixed ration. Cows averaged 80 +/- 12.5 d in milk at the beginning of the trial. Rumen pH, concentration of total and individual volatile fatty acids, microbial protein outflow, and microbial profiles were not affected by treatment. Ruminal ammonia-N concentration was increased by OV compared with the control (5.3 vs. 4.3 mM). Rumen methane production, which was measured only within 8 h after feeding, was decreased by OV. Intake of dry matter (average of 26.6 +/- 0.83 kg/d) and apparent total tract digestibly of nutrients did not differ between treatments. Average milk yield, milk protein, lactose, and milk urea nitrogen concentrations were unaffected by treatment. Mill; fat content was increased and 3.5% fat-corrected milk yield tended to be increased by OV, compared with the control (3.29 vs. 3.12% and 42.4 vs. 41.0 kg/d, respectively). Fat-corrected (3.5%) milk feed efficiency and milk net energy for lactation (NE(L)) efficiency (milk NE(L) divided by NE(L) intake) were increased by OV compared with the control (1.64 vs. 1.54 kg/kg and 68.0 vs. 64.4%, respectively). Milk sensory parameters were not affected by treatment. Urinary and fecal N losses, and manure ammonia and methane emissions were unaffected by treatment. Under the current experimental conditions, supplementation of dairy cow diets with 500 g/d of OV increased milk fat concentration, feed and milk NE(L) efficiencies, and tended to increase 3.5% fat-corrected milk yield. The sizable decrease in rumen methane production with the OV supplementation occurred within 8 h after feeding and has to be interpreted with caution due to the large within-and between-animal variability in methane emission estimates. The OV was introduced into the rumen as a pulse dose at the time of feeding, thus most likely having larger effect on methane production during the period when methane data were collected. It is unlikely that methane production will be affected to the same extent throughout the entire feeding cycle.

AB Cross-linking of lignin to arabinoxylan by ferulates limits in vitro rumen digestibility of grass cell walls. The effect of ferulate cross-linking on dry matter intake (DMI), milk production, and in vivo digestibility was investigated in ad libitum and restricted-intake digestion trials with lambs, and in a dairy cow performance trial using the low-ferulate sfe corn mutant. Silages of 5 inbred corn lines were fed: W23, 2 W23sfe lines (M04-4 and M04-21), B73, and B73bm3. As expected, the W23sfe silages contained fewer ferulate ether cross-links and B73bm3 silage had a lower lignin concentration than the respective genetic controls. Silages were fed as the sole ingredient to 4 lambs per silage treatment. Lambs were confined to metabolism crates and fed ad libitum for a 12-d adaptation period followed by a 5-d collection period of feed refusals and feces. Immediately following the ad libitum feeding trial, silage offered was limited to 2% of body weight. After a 2-d adaptation to restricted feeding, feed refusals and feces were collected for 5 d. Seventy Holstein cows were blocked by lactation, days in milk, body weight, and milk production and assigned to total mixed ration diets based on the 5 corn silages. Diets were fed for 28 d and data were collected on weekly DMI and milk production and composition. Fecal grab samples were collected during the last week of the lactation trial for estimation of feed digestibility using acid-insoluble ash as a marker. Silage, total mixed ration, feed refusals, and fecal samples were analyzed for crude protein, starch, neutral detergent fiber (NDF), cell wall polysaccharides, and lignin. The W23sfe silages resulted in lower DMI in the ad libitum trial than the W23 silage, but DMI did not differ in the restricted trial. No differences were observed for NDF or cell wall polysaccharide digestibility by lambs with restricted feeding, but the amount of NDF digested daily increased for lambs fed the M04-21 W23sfe silage ad libitum. Lambs were less selective against NDF and lignin when offered W23sfe silages. The B73bm3 silage did not affect DMI or digestibility of cell walls at the restricted feeding level, but total daily NDF digested was greater at ad libitum intake. Intake, milk production, and cell wall digestibility were greater for cows fed diets containing W23sfe silages than for those fed W23 silage. Although milk production was greater for the B73bm3 diet, DMI and cell wall digestibility were not altered. Cows were less selective against cell wall material when fed both W23sfe and B73bm3 silages. Reduced ferulate cross-linking in sfe corn silage is a new genetic mechanism for improving milk production.

AB Corn stover that had been treated with vapor-phase diethyl oxalate released a mixture of mono- and oligosaccharides consisting mainly of xylose and glucose. Following overliming and neutralization, a d-xylulokinase mutant of Pichia stipitis, FPL-YS30 (xyl3-a dagger 1), converted the stover hydrolysate into xylitol. This research examined the effects of phosphoric or gluconic acids used for neutralization and urea or ammonium sulfate used as nitrogen sources. Phosphoric acid improved color and removal of phenolic compounds. d-Gluconic acid enhanced cell growth. Ammonium sulfate increased cell yield and maximum specific cell growth rate independently of the acid used for neutralization. The highest xylitol yield (0.61 g(xylitol)/g(xylose)) and volumetric productivity (0.18 g(xylitol)/g(xylose) l) were obtained in hydrolysate neutralized with phosphoric acid. However, when urea was the nitrogen source the cell yield was less than half of that obtained with ammonium sulfate.

ID ENERGY IMBALANCE; CHILDREN; OBESITY; GAP
AB Limited data are available on the source of usual nutrient intakes in the United States. This analysis aimed to assess contributions of micronutrients to usual intakes derived from all sources (naturally occurring, fortified and enriched, and dietary supplements) and to compare usual intakes to the Dietary Reference Intake for U.S. residents aged >= 2 y according to NHANES 2003-2006 (n = 16,110). We used the National Cancer Institute method to assess usual intakes of 19 micronutrients by source. Only a small percentage of the population had total usual intakes (from dietary intakes and supplements) below the estimated average requirement (EAR) for the following: vitamin B-6 (8%), folate (8%), zinc (8%), thiamin, riboflavin, niacin, vitamin B-12, phosphorus, iron, copper, and selenium (<6% for all). However, more of the population had total usual intakes below the EAR for vitamins A, C, D, and E (34, 25, 70, and 60%, respectively), calcium (38%), and magnesium (45%). Only 3 and 35% had total usual intakes of potassium and vitamin K, respectively, greater than the adequate intake. Enrichment and/or fortification largely contributed to intakes of vitamins A, C, and D, thiamin, iron, and folate. Dietary supplements further reduced the percentage of the population consuming less than the EAR for all nutrients. The percentage of the population with total intakes greater than the tolerable upper intake level (UL) was very low for most nutrients, whereas 10.3 and 8.4% of the population had intakes greater than the UL for niacin and zinc, respectively. Without enrichment and/or fortification and supplementation, many Americans did not achieve the recommended micronutrient intake levels set forth in the Dietary Reference Intake. J.

Recent studies in plant virus evolution are revealing that genetic structure and behavior of virus and viroid populations can explain important pathogenic properties of these agents, such as host resistance breakdown, disease severity, and host shifting, among others. Genetic variation is essential for the survival of organisms. The exploration of how these subcellular parasites generate and maintain a certain frequency of mutations at the intra- and inter-host levels is revealing novel molecular virus plant interactions. They emphasize the role of host environment in the dynamic genetic composition of virus populations. Functional genomics has identified host factors that are transcriptionally altered after virus infections. The analyses of these data by means of systems biology approaches are uncovering critical plant genes specifically targeted by viruses during host adaptation. Also, a next-generation re-sequencing approach of a whole virus genome is opening new avenues to study virus recombination and the relationships between intra-host virus composition and pathogenesis. Altogether, the analyzed data indicate that systematic disruption of some specific parameters of evolving virus populations could lead to more efficient ways of disease prevention, eradication, or tolerable virus plant coexistence.

Information on the spatial distribution of plant disease can be utilized to implement efficient and spatially targeted disease management interventions. We present a pathogen-generic method to estimate the spatial distribution of a plant pathogen using a stochastic optimization process which is epidemiologically motivated. Based on an initial sample, the method simulates the individual spread processes of a pathogen between patches of host to generate optimized spatial distribution maps. The method was tested on data sets of Huanglongbing of citrus and was compared with a kriging method from the field of geostatistics using the well-established kappa statistic to quantify map accuracy. Our method produced accurate maps of disease distribution with kappa values as high as 0.46 and was able to outperform the kriging method across a range of sample sizes based on the kappa statistic. As expected, map accuracy improved with sample size but there was a high amount of variation between different random sample placements (i.e., the spatial distribution of samples). This highlights the importance of sample placement on the ability to estimate the spatial distribution of a plant pathogen and we thus conclude that further research into sampling design and its effect on the ability to estimate disease distribution is necessary.

Pantoea agglomerans E325, the active ingredient in a commercial product for fire blight control, was previously shown in vitro to produce a unique alkaline- and phosphate-sensitive antibiotic specific to Erwinia amylovora. Antibiosis was evaluated as a mode of antagonism on flower stigmas using two antibiosis-deficient mutants. On King's medium B, mutants E325ad1 and E325ad2 have stable smooth-butyrous or hypermucoid colony morphologies, respectively, and the parental strain E325 exhibits phenotypic plasticity with predominantly hypermucoid colonies accompanied by slower-growing, smooth-butyrous colonies. Mutants were tested against E. amylovora on stigmas of detached flowers of crab apple (Malus mandshurica) in growth chambers and apple (Malus domestica) in the orchard. Epiphytic fitness of the antibiosis-negative mutants was similar or greater than the parental strain as determined by relative area under the population curve (RAUPC). In laboratory and orchard trials, both mutants had significantly lower inhibitory activity against the pathogen (i.e., less reduction of E. amylovora RAUPC) compared with the parental strain. E325 and the mutants caused similar decreases in pH in a broth medium, indicating that acidification, which was previously reported as a possible mechanism of pathogen inhibition on stigmas, is not directly related to antibiosis. In this study we provide the first evidence for E325 antibiosis involved in E. amylovora growth suppression on apple flower stigmas.

Huanglongbing is an economically damaging disease of citrus associated with infection by 'Candidatus Liberibacter asiaticus'. Transmission of the organism via infection of seeds has not been demonstrated but is a concern since some citrus varieties, particularly those used as rootstocks in commercial plantings are propagated from seed. We compared the incidence of detection of 'Ca. Liberibacter asiaticus' DNA in individual fruit peduncles, seed coats, seeds, and in germinated seedlings from 'Sanguenelli' sweet orange and 'Conners' grapefruit fruits sampled from infected trees. Using real-time quantitative PCR (qPCR) we detected pathogen DNA in nucleic acid extracts of 36 and 100% of peduncles from 'Sanguenelli' and from 'Conners' fruits, respectively. We also detected pathogen DNA in extracts of 37 and 98% of seed coats and in 1.6 and 4% of extracts from the corresponding seeds of 'Sanguenelli' and 'Conners', respectively. Small amounts of pathogen DNA were detected in 10% of 'Sanguenelli' seedlings grown in the greenhouse, but in none of 204 extracts from 'Conners' seedlings. Pathogen DNA was detected in 4.9% and in 89% of seed coats peeled from seeds of 'Sanguenelli' and 'Conners' which were germinated on agar, and in 5% of 'Sanguenelli' but in none of 164 'Conners' seedlings which grew from these seeds on agar. No pathogen DNA was detected in 'Ridge Pineapple' tissue at 3 months post-grafting onto 'Sanguenelli' seedlings, even when pathogen DNA had been detected initially in the 'Sanguenelli' seedling. Though the apparent colonization of 'Conners' seeds was more extensive and nearly uniform compared with 'Sanguenelli' seeds, no pathogen DNA was detected in 'Conners' seedlings grown from these seeds. For either variety, no association was established between the presence of pathogen DNA in fruit peduncles and seed coats and in seedlings.

Mycosphaerella graminicola causes Septoria tritici blotch (STB) in wheat (Triticum aestivum) and is considered one of the most devastating pathogens of that crop in the United States. Although the genetic structures of M. graminicola populations from different countries have been analyzed using various molecular markers, relatively little is known about Al. graminicola populations from geographically distinct areas of the United States and, in particular, of those from spring versus winter wheat. These are exposed to great differences in environmental conditions, length and season of host-free periods, and resistance sources used in geographically separated wheat breeding programs. Thus, there is more likely to be genetic differentiation between populations from spring versus winter wheat than there is among those within each region. To test this hypothesis, 330 single-spore isolates of M. graminicola representing 11 populations (1 from facultative winter wheat in California, 2 from spring wheat in North Dakota, and 8 from winter wheat in Indiana and Kansas) were analyzed for mating type frequency and for genetic variation at 17 microsatellite or simple-sequence repeat (SSR) loci. Analysis of clone-corrected data revealed an equal distribution of both mating types in the populations from Kansas, Indiana, and North Dakota, but a deviation from a I:I ratio in the California population. In total, 306 haplotypes were detected, almost all of which were unique in all II populations. High levels of gene diversity (H = 0.31 to 0.56) were observed within the 11 populations. Significant (P <= 0.05) gametic disequilibrium, as measured by the index of association (rBarD), was observed in California, one Indiana population (IND, and three populations (KS1, KS2, and KS3) in Kansas that could not be explained by linkage. Corrected standardized fixation index (G ''(ST)) values were 0.000 to 0.621 between the 11 populations and the majority of pairwise comparisons were statistically significant (P <= 0.001), suggesting some differentiation between populations. Analysis of molecular variance showed that there was a small but statistically significant level of genetic differentiation between populations from spring versus winter wheat. However, most of the total genetic variation (>98%) occurred within spring and winter wheat regions while <2% was due to genetic differentiation between these regions. Taken together, these results provide evidence that sexual recombination occurs frequently in the M. graminicola populations sampled and that most populations are genetically differentiated over the major spring- and winter-wheat-growing regions of the United States.

AB Fusarium head blight (FHB), caused principally by Gibberella zeae (Fusarium graminearum), is a devastating disease of small grains such as wheat and barley worldwide. Grain infected with G. zeae may be contaminated with trichothecene mycotoxins such as deoxynivalenol (DON) and nivalenol (NIV). Strains of G. zeae that produce DON may also produce acetylated derivatives of DON: 3-acetyl-DON (3-ADON) and 15-acetyl-DON (15-ADON). Gradients (clines) of 3-ADON genotypes in Canada have raised questions about the distribution of G. zeae trichothecene genotypes in wheat fields in the eastern USA. Tri3 and Tri12 genotypes were evaluated in 998 isolates of G. zeae collected from 39 winter wheat fields in New York (NY), Pennsylvania (PA), Maryland (MD), Virginia (VA), Kentucky (KY) and North Carolina (NC). Ninety-two percent (919/998) of the isolates were 15-ADON, 7% (69/998) were 3-ADON, and 1% (10/998) was NIV. A phylogenetic analysis based on portions of three genes (PHO, RED and URA) from 23 isolates revealed two species of Fusarium (F. graminearum sensu stricto and one isolate of F. cerealis (synonym F. crookwellense)). An increasing trend of 3-ADON genotypes was observed from NC (south) to NY (north). Punctuated episodes of atmospheric transport may favour a higher frequency of 3-ADON genotypes in the northeastern USA, near Canada, compared with the mid-Atlantic states. Discoveries of the NIV genotype in NY and NC indicate the need for more intensive sampling in the surrounding regions.

AB The objective of this study was to describe and quantify the distribution of citrus canker lesions (caused by Xanthomonas citri subsp. citri) on the surface of grapefruits, and provide evidence for splash-driven infection of fruit. Based on fruit diameter, each fruit was sliced in four by taking three horizontal planes across the vertical axis such that each horizontal zone (Z1-Z4, from peduncle to flower scar) had the same vertical height. Each zone had equal surface area. Lesion number was counted on each zone of the fruit. Although lesion number among fruits was variable, both lesion number and percentage of total lesions showed a decline from the uppermost zone (lesion number: 10 5, 7 0, 3 4 and 2 4; percentage: 44 6, 30 5, 14 4 and 10 5 on Z1-Z4, respectively). General linear modelling (GLM) using a Poisson distribution with a log-link function demonstrated a significant effect of zone and cultivar on lesion number, and significant differences between all zones and both cultivars. An analysis of covariance showed no effect of lesion number on fruit size, although cultivars differed in total lesion count. Canker-susceptible citrus fruit is susceptible for a prolonged period after fruit set and minimizing inoculum and reducing wind speed and splash, and use of copper sprays during that period, will help reduce disease on fruit, particularly on the upper surfaces that appear to be more prone to infection.

AB The main aim of this study was to examine affective linkages between competition-related and competition-extraneous concern domains. A secondary purpose was to establish the contributions of pre-competition affects to post-competition performance appraisals, independent of pre-competition performance expectations. Thirty-nine highly skilled male martial artists were assessed at five random times a day for a week and 1 h before a major competition on affective states and sources of concern. They also reported their performance expectations and post-competition performance appraisals. Affective states triggered by competition-related and competition-extraneous concerns persisted in time. Carry-over effects were stronger after reports of competition-related concerns, emphasizing the subjective importance of the competitive event. Although positive (enjoyment and surprise) and negative (sadness and guilt) affective spill-over was observed from competition-extraneous to competition-related concerns, the reverse held true only for disgust. These findings may be due to the athletes' ability to regulate affective reactions within a sporting setting, in particular. Spill-over from competition-extraneous to competition-related concerns is indicative of a lesser degree of control over work/study and family life. Given that average weekly negative affects and anger/disgust were independent predictors of post-competition performance appraisals, the phenomenon of spill-over and other affective linkage mechanisms in sport warrant further investigation.

AB The response of soil microbial communities following changes in land-use is governed by multiple factors. The objectives of this study were to investigate (i) whether soil microbial communities track the changes in aboveground vegetation during succession; and (ii) whether microbial communities return to their native state over time. Two successional gradients with different vegetation were studied at the W. K. Kellogg Biological Station, Michigan. The first gradient comprised a conventionally tilled cropland (Cr). mid-succession forest (SF) abandoned from cultivation prior to 1951, and native deciduous forest (OF). The second gradient comprised the Cr cropland, early-succession grassland (ES) restored in 1989, and long-term mowed grassland (MG). With succession, the total microbial PLFAs and soil microbial biomass C consistently increased in both gradients. While bacterial rRNA gene diversity remained unchanged, the abundance and composition of many bacterial phyla changed significantly. Moreover, microbial communities in the relatively pristine DF and MG soils were very similar despite major differences in soil properties and vegetation. After > 50 years of succession, and despite different vegetation, microbial communities in SF were more similar to those in mature DF than in CT. In contrast, even after 17 years of succession, microbial communities in ES were more similar to a than endpoint MG despite very different vegetation between CT and ES. This result suggested a lasting impact of cultivation history on the soil microbial community. With conversion of deciduous to conifer forest (CF), there was a significant change in multiple soil properties that correlated with changes in microbial biomass, rRNA gene diversity and community composition. In conclusion, history of land-use was a stronger determinant of the composition of microbial communities than vegetation and soil properties. Further, microbial communities in disturbed soils apparently return to their native state with time. (C) 2011 Elsevier Ltd. All rights reserved.

AB Background: Fat mass is thought to be protective against osteoporosis, primarily because of its weight-bearing effect. Few studies have evaluated the association between abdominal fat mass (AFM) and bone health beyond its weight-bearing effect.
Objective: We tested the hypothesis that higher body weight-adjusted AFM is associated with poor bone health.
Design: A cross-sectional study was conducted in 629 Puerto Rican adults aged 47-79 y. Bone mineral density (BMD) of the femoral neck, trochanter, total femur, and lumbar spine (L2-L4) were measured by using dual-energy X-ray absorptiometry (DXA). AFM and total fat mass (TFM) were assessed by using body-composition software from whole-body DXA scans. Osteoporosis and osteopenia were defined as T-scores <= -2.5 and -1.0 to -2.5 SD, respectively, at the respective bone site.
Results: After confounders were controlled for, body weight-adjusted AFM was inversely associated with BMD at all 4 bone sites in women and at the femoral neck in men. For TFM, small inverse associations were seen at the trochanter and total femur in women. In men, similar associations were seen at the 3 femur sites. In both sexes, the odds for osteoporosis or osteopenia at each of the femoral sites increased by 10-16% for every 100-g increase in body weight-adjusted AFM.
Conclusions: Higher AFM was associated with poor bone health in this Puerto Rican sample. Efforts to reduce abdominal obesity will not only reduce the risk of chronic disease but may also improve bone health. This trial is registered at clinicaltrials.gov as NCT01231958.

AB There is a need to seek non-conventional seed oil sources for biodiesel production due to issues such as supply and availability as well as food versus fuel. In this context, Milo (Thespesia populnea L.) seed oil was investigated for the first time as a potential non-conventional feedstock for preparation of biodiesel. This is also the first report of a biodiesel fuel produced from a feedstock containing cyclic fatty acids as T. populnea contains 8,9-methylene-8-heptadecenoic (malvalic) and smaller amounts of two cyclopropane fatty acids besides greater amounts of linoleic, oleic and palmitic acids. The crude oil extracted from T. populnea seed was transesterified under standard conditions with sodium methoxide as catalyst. Biodiesel derived from T. populnea seed oil exhibited fuel properties of density 880 kg m(-3), kinematic viscosity 4.25 mm(2)/s; cetane number 59.8; flash point 176 degrees C; cloud point 9 degrees C; pour point 8 degrees C; cold filter plugging point 9 degrees C; sulfur content 11 mg kg(-1); water content 150 mg kg(-1); ash content 15 mg kg(-1); and acid value as KOH 250 mg kg(-1). The oxidative stability of 2.91 h would require the use of antioxidants to meet specifications in standards. Generally, most results compared well with ASTM D6751 and EN 14214 specifications.

AB 1. Barriers to immigration, all else being equal, should in principle depress local abundance and reduce local species richness. These issues are particularly relevant to stream-dwelling species when improperly designed road crossings act as barriers to migration with potential impacts on the viability of upstream populations. However, because abundance and richness are highly spatially and temporally heterogeneous and the relative importance of immigration on demography is uncertain, population-and community-level effects can be difficult to detect.
2. In this study, we tested the effects of potential barriers to upstream movements on the local abundance and species richness of a diverse assemblage of resident stream fishes in the Monongahela National Forest, West Virginia, U. S. A. Fishes were sampled using simple standard techniques above-and below road crossings that were either likely or unlikely to be barriers to upstream fish movements (based on physical dimensions of the crossing). We predicted that abundance of resident fishes would be lower in the upstream sections of streams with predicted impassable barriers, that the strength of the effect would vary among species and that variable effects on abundance would translate into lower species richness.
3. Supporting these predictions, the statistical model that best accounted for variation in abundance and species richness included a significant interaction between location (upstream or downstream of crossing) and type (passable or impassable crossing). Stream sections located above predicated impassable culverts had fewer than half the number of species and less than half the total fish abundance, while stream sections above and below passable culverts had essentially equivalent richness and abundance.
4. Our results are consistent with the importance of immigration and population connectivity to local abundance and species richness of stream fishes. In turn, these results suggest that when measured at appropriate scales (multiple streams within catchments), with simple protocols amenable to use by management agencies, differences in local abundance and species richness may serve as indicators of the extent to which road crossings are barriers to fish movement and help determine whether road-crossing improvements have restored connectivity to stream fish populations and communities.

AB Asymptomatic Salmonella-carrier pigs present a major problem in preharvest food safety, with a recent survey indicating >50% of swine herds in the United States have Salmonella-positive animals. Salmonella-carrier pigs serve as a reservoir for contamination of neighbouring pigs, abattoir pens and pork products. In addition, fresh produce as well as water can be contaminated with Salmonella from manure used as fertilizer. Control of Salmonella at the farm level could be through genetic improvement of porcine disease resistance, a potentially powerful method of addressing preharvest pork safety. In this research, we integrate gene expression profiling data and sequence alignment-based prediction of single nucleotide polymorphisms (SNPs) to successfully identify SNPs in functional candidate genes to test for the associations with swine response to Salmonella. A list of 2527 genes that were differentially regulated in porcine whole blood in response to infection with Salmonella enterica serovar Typhimurium were selected. In those genes, SNPs were predicted using ANEXdb alignments based on stringent clustering of all publically available porcine cDNA and expressed sequence tag (EST) sequences. A set of 30 mostly non-synonymous SNPs were selected for genotype analysis of four independent populations (n = 750) with Salmonella faecal shedding or tissue colonization phenotypes. Nine SNPs segregated with minor allele frequency >= 15% in at least two populations. Statistical analysis revealed SNPs associated with Salmonella shedding, such as haptoglobin (HP, p = 0.001, q = 0.01), neutrophil cytosolic factor 2 (NCF2 #2, p = 0.04, q = 0.21) and phosphogluconate dehydrogenase (p = 0.066, q = 0.21). These associations may be useful in identifying and selecting pigs with improved resistance to this bacterium.

AB Application of AI in extensive beef cattle production would be facilitated by protocols that effectively synchronize ovarian follicular development and ovulation to enable fixed-time AI (TAI). The objectives were to determine whether use of a controlled internal drug release (CIDR) device to administer progesterone in a GnRH-based estrous synchronization protocol would optimize blood progesterone concentrations, improve synchronization of follicular development and estrus, and increase pregnancy rates to TAI in beef cows. Beef cows (n = 1,240) in 6 locations within the US Meat Animal Research Center received 1 of 2 treatments: 1) an injection of GnRH [100 mu g intramuscularly (i.m.)] followed by PGF(2 alpha) (PGF; 25 mg i.m.) 7 d later (CO-Synch), or 2) CO-Synch plus a CIDR during the 7 d between GnRH and PGF injections (CO-Synch + CIDR). Cows received TAI and GnRH (100 mu g i.m.) at 60 h after PGF. Progesterone was measured by RIA in blood samples collected 2 wk before and at initiation of treatment (d 0) and at PGF injection (d 7). Estrous behavior was monitored by Estrotect Heat Detectors. Pregnancy was diagnosed by ultrasonography 72 to 77 d after TAI. Plasma progesterone concentrations did not differ (P > 0.10) between synchronization protocols at first GnRH injection (d 0), but progesterone was greater (P < 0.01) at PGF injection (d 7) in cows receiving CO-Synch + CIDR vs. CO-Synch as a result of fewer CIDR-treated cows having progesterone <= 1 ng/mL at PGF (10.7 vs. 29.6%, respectively). A greater (P < 0.01) proportion of CO-Synch + CIDR vs. CO-Synch cows were detected in estrus within 60 h after PGF (66.7 vs. 57.8 +/- 2.6%, respectively) and a greater (P < 0.01) proportion were pregnant to TAI (54.6 vs. 44.3 +/- 2.6%, respectively). For both synchronization protocols, cows expressing estrus within 60 h before TAI had a greater pregnancy rate than cows without estrus. For cows with plasma progesterone <= 1 ng/mL at PGF injection, CO-Synch + CIDR increased pregnancy rate (65.2 +/- 5.9 vs. 30.8 +/- 3.4% with vs. without CIDR), whereas pregnancy rates did not differ (P > 0.10) between protocols (52.1 +/- 2.1 vs. 50.0 +/- 2.4%, respectively) when progesterone was >1 ng/mL (treatment x progesterone; P < 0.01). Inclusion of a CIDR in the synchronization protocol increased plasma progesterone concentration, proportion of cows detected in estrus, and pregnancy rate; however, the increase in pregnancy rate from inclusion of the CIDR was primarily in cows with decreasing or low endogenous progesterone secretion during treatment.

AB Apoptosis via the intrinsic caspase 9 pathway can be induced by oxidative stressors hydrogen peroxide (H2O2) and N-(4 hydroxyphenol) rentinamide (fenretinide), a synthetic retinoid. Accelerated muscle atrophy and proteolysis in muscle-wasting conditions have been linked to oxidative stress and activated protease systems. Therefore, the hypothesis of this study was that proteolysis of myofibrillar proteins could be manipulated through the induction or inhibition of the caspase system. After slaughter, LM and supraspinatus muscles from callipyge (n = 5) and normal (n = 3) lambs were excised, finely diced, and incubated with treatment buffers containing oxidative stressors fenretinide or H2O2, recombinant caspase 3, caspase-specific inhibitor N-acetyl-Asp-Glu-Val-Asp-CHO (DEVD), or control solution. Muscle samples were incubated for 1, 2, 7, and 21 d at 4 degrees C. Activation of the initiator caspase, caspase 9, and myofibrillar protein degradation was determined by SDS-PAGE and Western blotting. Results showed that fenretinide, H2O2, and recombinant caspase 3 increased (P < 0.05) proteolysis of myofibril proteins, whereas DEVD inhibited degradation (P < 0.05). Proteolysis of myofibrillar proteins increased with incubation time (P < 0.0001), and incubation time x treatment interactions (P < 0.05) indicated that the treatment effects did not all occur at the same rate. This study has shown that manipulation of the caspase system through induction or inhibition of activity can affect degradation of myofibrillar proteins, providing further evidence that the caspase system could be involved in postmortem proteolysis and tenderization. However, these stimulated changes were not sufficient to overcome the lack of proteolysis that is characteristic of muscle from callipyge lambs.

AB Confined animal production systems produce increased bioaerosol concentrations, which are a potential respiratory health risk to individuals on site and downwind. In this longitudinal study, airborne endotoxin and microorganisms were collected during the spring, summer, and fall at a large, open-freestall dairy in southern Idaho. Compared with the background ambient atmosphere, both endotoxin and culturable heterotrophic bacteria concentrations were up to several-hundred-fold greater 50 m downwind from the facility, then decreased to near background concentrations at 200 m. However, downwind fungi concentrations were not increased above background concentrations. At 50 m downwind, the average inhalable endotoxin concentration ranged from 5 to 4,243 endotoxin units per m(-3), whereas bacteria concentrations ranged from 102 to 104 cfu per m(-3) of air. Although the bioaerosol concentrations did not follow a seasonal trend, they did significantly correlate with meteorological factors. Increasing temperature was found to be positively correlated with increasing bacteria (r = 0.15, P < 0.05), fungi (r = 0.14, P < 0.05), and inhalable endotoxin (r = 0.32, P < 0.001) concentrations, whereas an inverse relationship occurred between the concentration and solar radiation. The airborne concentrations at 50 m were also found to be greatest at night, which can likely be attributed to changes in animal activity and wind speed and reduced exposure of the airborne microorganisms to UV radiation.

AB Surgical castration is performed on most male piglets in the United States. However, castration is painful and analgesics have been considered to relieve pain. Inhalant gases with analgesic properties allow for a fast induction, have short-term and reversible effects, and are a needle-free option. Nitrous oxide (N(2)O; "laughing gas") has been widely used in human surgery and dental offices as an analgesic, sedative, and anxiolytic drug, yet N(2)O has not been thoroughly investigated for use in farm animals. We hypothesized that the analgesic effect of N(2)O could reduce the pain experienced by piglets during or immediately after castration. Twenty-four male piglets, from 12 litters, were castrated at 3 d of age. One piglet received N(2)O and a littermate received air as a control. After 150 s of exposure to the gas, castration was performed while the piglet remained exposed to the gas. Agitation scores and total vocalization length were recorded during castration. Behavioral observations were continued for 3 d postcastration by using a 5-min scan-sampling method for 4 h the first morning and for 2-h periods in the morning and afternoon of each day thereafter. Body weight gain was measured on the day before castration, at 3 d postcastration, and at weaning. Data were analyzed using a mixed model in SAS (Cary, NC). Nitrous oxide successfully induced anesthesia in all N(2)O piglets, as validated by a skin pinch test and the loss of the palpebral reflex. Total vocalization length was shorter in piglets receiving N(2)O during the induction phase (P = 0.003) but was not different during castration itself because piglets receiving N(2)O awoke and vocalized as much as control piglets (P = 0.87). Agitation scores during the whole procedure were reduced in piglets receiving N(2)O in both frequency (P = 0.005) and intensity (P = 0.026). For 2 h after castration, piglets receiving N(2)O displayed less huddling behavior than did control piglets (P = 0.01). Over the 3 d, piglets receiving N(2)O performed more tail wagging (P = 0.02) and tended to show fewer sleep spasms (P = 0.06) than did control piglets. Piglets given N(2)O tended to have a reduced growth rate compared with control piglets at 3 d postcastration and at weaning (P = 0.05 and P = 0.06, respectively). Nitrous oxide was effective in inducing anesthesia in neonatal piglets during handling. Nonetheless, its analgesic effects appeared insufficient in preventing castration-induced pain.

AB The relationships between the vulnerability of stem xylem to cavitation, stomatal conductance, stomatal density, and leaf and stem water potential were examined in six hybrid poplar (P38P38, Walker, Okanese, Northwest, Assiniboine and Berlin) and balsam poplar (Populus balsamifera) clones. Stem xylem cavitation resistance was examined with the Cavitron technique in well-watered plants grown in the greenhouse. To investigate stomatal responses to drought, plants were subjected to drought stress by withholding watering for 5 (mild drought) and 7 (severe drought) days and to stress recovery by rewatering severely stressed plants for 30 min and 2 days. The clones varied in stomatal sensitivity to drought and vulnerability to stem xylem cavitation. P38P38 reduced stomatal conductance in response to mild stress while the balsam poplar clone maintained high leaf stomatal conductance under more severe drought stress conditions. Differences between the severely stressed clones were also observed in leaf water potentials with no or relatively small decreases in Assiniboine, P38P38, Okanese and Walker. Vulnerability to drought-induced stem xylem embolism revealed that balsam poplar and Northwest clones reached loss of conductivity at lower stem water potentials compared with the remaining clones. There was a strong link between stem xylem resistance to cavitation and stomatal responsiveness to drought stress in balsam poplar and P38P38. However, the differences in stomatal responsiveness to mild drought suggest that other drought-resistant strategies may also play a key role in some clones of poplars exposed to drought stress.

SUBCELLULAR-LOCALIZATION
AB Cantharidin is a natural compound isolated from the blister beetle (Epicauta spp.). It is a potent inhibitor of protein serine/threonine phosphatases (PPPs), especially PP2A and PP4. Protein phosphatases and kinases maintain a sensitive balance between dephosphorylated and phosphorylated forms of appropriate proteins, thereby playing important roles in signal transduction pathways and regulation of gene expression, cellular proliferation, cell differentiation, apoptosis and other processes. The foliage of 12-day-old Arabidopsis thaliana seedlings was treated with 200 mu M (IC(30)) of the PPP inhibitor cantharidin, and the entire transcriptome profile was determined by microarray analysis at 2, 10 and 24 h after treatment. The transcription of approximately 10% (2577) of the 24 000 genes of Arabidopsis changed significantly (P <= 0.05 and signal log ratios: >= 1 or <=-1) after treatment. Inhibition of PPPs significantly reduced transcription of genes associated with auxin and light signaling and induced expression of genes involved in the hypersensitive response and in flagellin and abscisic acid signaling. The great variety of up- and downregulated genes in this microarray experiment implied that cantharidin interfered with the activities of PPPs that interact directly or indirectly with receptors or are located near the beginning of signal transduction pathways. In many cases, PPPs interact with protein complexes of various receptors such as ethylene or light sensors localized in different cell compartments. They function as negative regulators modifying receptor functions, thus altering signaling that influences transcriptional responses.

AB Chickpea (Cicer arietinum L.) is an important legume crop in the semi-arid regions of Asia and Africa. Gains in crop productivity have been low however, particularly because of biotic and abiotic stresses. To help enhance crop productivity using molecular breeding techniques, next generation sequencing technologies such as Roche/454 and Illumina/Solexa were used to determine the sequence of most gene transcripts and to identify drought-responsive genes and gene-based molecular markers. A total of 103 215 tentative unique sequences (TUSs) have been produced from 435 018 Roche/454 reads and 21 491 Sanger expressed sequence tags (ESTs). Putative functions were determined for 49 437 (47.8%) of the TUSs, and gene ontology assignments were determined for 20 634 (41.7%) of the TUSs. Comparison of the chickpea TUSs with the Medicago truncatula genome assembly (Mt 3.5.1 build) resulted in 42 141 aligned TUSs with putative gene structures (including 39 281 predicted intron/splice junctions). Alignment of similar to 37 million Illumina/Solexa tags generated from drought-challenged root tissues of two chickpea genotypes against the TUSs identified 44 639 differentially expressed TUSs. The TUSs were also used to identify a diverse set of markers, including 728 simple sequence repeats (SSRs), 495 single nucleotide polymorphisms (SNPs), 387 conserved orthologous sequence (COS) markers, and 2088 intron-spanning region (ISR) markers. This resource will be useful for basic and applied research for genome analysis and crop improvement in chickpea.

AB This is the first report of microsatellite markers for Cyperus rotundus. A total of 191 sequence-specific microsatellite markers were isolated and used to screen 12 accessions of C. rotundus and one accession of Cyperus esculentus collected from 10 different countries. Polymorphisms were observed in 49% of the markers tested, 22% of the markers were monomorphic and 29% had weak or no amplification. The best 57 markers are reported, and cluster analysis was used to analyse their resolving power. BLASTx screening of the contig sequences was also performed. Multiallelic loci over all samples ranged from 24% to 60%. The maximum number of alleles detected by the markers suggests a polyploidy nature of all C. rotundus accessions tested, except for the sample N25-Brazil. Chromosome number was determined for N12-Taiwan and used as an internal flow cytometry standard to estimate the amount of DNA within haploid nuclei of the remaining material. Chromosome numbers estimated for C. rotundus were 16 and 24. The markers identified in this study can be used for the identification of biotypes and detection of potential crosses of C. rotundus, to implement management practices for the effective control of this weed.

AB Maize is unique among cereal grasses because of its monoecious flowering habit. Male flowers are normally restricted to the tassel that terminates the primary shoot, whereas female flowers occur as ears at the terminal nodes of lateral branches. We observed Ki14, a tropical maize inbred that produces an ear tipped by a staminate (male) spike under certain environmental conditions, such as long daylengths. Recombinant inbred lines derived from the cross between temperate line B97, which was never observed to produce a staminate ear tip, and Ki14 segregated for the trait under long daylengths. Some progeny lines that had even longer staminate tips than Ki14 were male fertile. We mapped three QTL controlling staminate ear tip using a two-part (binomial plus normal) model. A major QTL on chromosome 3 had a large effect on penetrance of the trait (whether a line would produce staminate ear tips or not) as well as its severity (the length of the staminate tip). This QTL seems to be linked to, but at a distinct position from, a previously mapped QTL controlling the proportion of staminate florets in ears in progeny from crosses between maize and teosinte. Two additional QTL affecting staminate ear tip severity overlapped with QTL controlling photoperiod response previously mapped in this population. Alleles conferring photoperiod sensitivity for delayed flowering at these QTL seem to enhance the production of staminate ear tips under long daylengths.

AB Codling moth is a major pest of apples and pears worldwide. Increasing knowledge of how this insect responds to environmental stress will improve field and post-harvest control measures used against it. The small heat shock proteins (sHsps) play a major role in cellular responses to environmental stressors. A degenerate oligonucleotide primer, designed against the conserved alpha-crystallin domain, was used in 3' rapid amplification of complementary DNA (cDNA) ends reactions to amplify transcripts encoding sHsps expressed in the codling moth cell line, Cp169, subjected to heat shock. Three full-length cDNAs were cloned from Cp169 cells that contained open reading frames encoding sHsps. The cDNA for CpHsp 19.8 was 795 bp encoding 177 amino acids. The cDNA for CpHsp 19.9 was 749 bp encoding 175 amino acids. The cDNA for CpHsp22.2 was 737 bp encoding 192 amino acids. Analysis of the protein sequences of the three CpHsps indicated the presence of 83 amino acids with homology to the alpha-crystallin domain. For each of the CpHsps, the alpha-crystallin domain was surrounded by divergent N- and C-terminal regions, consistent with the conserved structural features of sHsps. Real-time polymerase chain reaction, used to determine the expression patterns of each of the sHsps in different developmental stages of codling moth revealed the presence of transcripts in all stages tested. Consistent with characteristics of other sHsps, expression of CpHsp transcripts were greatly enhanced when insects were subjected to heat shock. The results of this research can be used as a guide to study the roles of sHsps in codling moth control using various post-harvest treatments.

TI Protein and glucogenic precursor supplementation: A nutritional strategy

AB Reproductive performance in young beef cows is often compromised due to a mismatch of physiological demands and suboptimal environmental conditions. Studies conducted at the Corona Range and Livestock Research Center from 2000 to 2007 evaluated 3 postpartum supplement strategies that varied in the amount of glucogenic potential (GP) supplied. Reproductive variables, milk production, and serum metabolites were used to assess supplement effectiveness and economics associated with 2- and 3-yr-old beef cows (n = 379) grazing native range. Supplements were individually fed twice/week at 1,135 g/d (2003 to 2004) or 908 g/d (all other years) and provided 1) 327 g of CP, 109 to 118 g of RUP (CON); 2) 327 to 341 g of CP, 142 to 157 g of RUP (RUP); or 3) 327 g of CP, 151 to 173 g of RUP + 40 to 100 g of propionate salt (PS; RUP+PS). Ultimately, total GP for CON, RUP, and RUP+PS was 44 to 47, 57 to 70, and 93 to 141 g, respectively. Blood samples were collected once/week (2000) or twice/week (2001 to 2007) for progesterone analysis to estimate days to resumption of estrus. Cows were exposed to bulls for 60 d or less, and pregnancy was confirmed by rectal palpation at weaning. Days to resumption of estrus after calving decreased linearly (P = 0.02), resulting in an increased pregnancy rate (P = 0.03) with increasing GP. Milk production exhibited a quadratic (P = 0.04) response to increasing GP, with cows fed RUP producing the most amount of milk. However, a linear decrease (P = 0.07) in days from BW nadir to estrus was found with increasing GP. Total kilograms of calf weaned per cow exposed for the supplemental year and subsequent year was increased linearly (P = 0.07) with increased GP. The improvement in pregnancy rate by supplementing RUP+ PS resulted in an increase in total revenue of 18% compared with CON-fed cows and 9.5% compared with RUP-fed cows in the subsequent year after supplementation. These data suggest feeding young cows additional GP in the form of PS allows for partitioning of nutrients away from milk production and toward reproduction, allowing for increased profitability by increasing pregnancy rates and decreasing days to resumption of estrus.

AB The land slug Meghimatium pictum (Stoliczka, 1873), native to China, is recorded for the first time in Brazil. This is also the first record of a species of the eastern Asiatic genus Meghimatium on the American continents. The species was identified using morphological criteria and analysis of the cytochrome oxidase subunit I, COI. Our records indicate this species is widely distributed in southern and southeastern Brazil, in the States of Sao Paulo, Parana, Santa Catarina and Rio Grande do Sul, in disturbed and natural areas. We morphologically characterize M. pictum (external characteristics, reproductive system, jaw and radula) and provide some biological information based on field observations. We also discuss when M. pictzun was probably introduced, from whence it came, possible pathways of introduction, and its characteristics as an invasive species and potential agricultural pest.

AB Four ascosporulating strains of an undescribed methanol-assimilating yeast species were isolated from forest habitats in Hungary. Three were recovered from rotten wood and one from leaves of a sessile oak (Quercus petraea). An additional isolate of the undescribed species sharing similar phenotypic characters with the above-noted strains was recovered from the gut of an unidentified beetle collected from under the bark of a coniferous tree in Bulgaria. A closely related, but somewhat divergent strain was recovered from insect frass in a Ponderosa pine (Pinus ponderosa) collected in New Mexico, USA. Analysis of the D1/D2 sequences of the LSU rRNA gene placed the new species in the Ogataea clade. The ITS and the D1/D2 LSU sequences of the rRNA gene repeats were compared for the above-noted strains and that of the type strain of Ogataea zsoltii, the closest neighbour among currently recognized Ogataea species. Their relatedness was investigated by parsimony network analysis as well. As a result of the sequence analysis, it was concluded that the six strains isolated from tree associated habitats represent a single new yeast species. Ogataea saltuana sp. nov. is proposed to accommodate these strains. The type strain NCAIM Y.01833(T) (CBS 10795(T), NRRL Y-48448(T)) was recovered from rotten wood of Scotch pine (Pinus silvestris) in Hungary. The GenBank accession number for the D1/D2 domain nuclear large subunit rRNA gene sequence of strain NCAIM Y.01833(T) (CBS 10795(T), NRRL Y-48448(T)) is EU327033. The MycoBank number of the new species is MB 519966.

AB Ogataea parapolymorpha sp. n. (NRRL YB-1982, CBS 12304, type strain), the ascosporic state of Candida parapolymorpha, is described. The species appears homothallic, assimilates methanol as is typical of most Ogataea species and forms hat-shaped ascospores in asci that become deliquescent. O. parapolymorpha is closely related to Ogataea angusta and Ogataea polymorpha. The three species can be resolved from gene sequence analyses but are unresolved from fermentation and growth reactions that are typically used for yeast identification. On the basis of multiple isolates, O. angusta is known only from California, USA, in association with Drosophila and Aulacigaster flies, O. parapolymorpha is predominantly associated with insect frass from trees in the eastern USA but O. polymorpha has been isolated from various substrates in the USA, Brazil, Spain and Costa Rica.

AB Dryocosmus kuriphilus (Hymenoptera: Cynipidae) is non-native to North America and induces formation of galls on petioles and leaves of all chestnut (Castanea spp., Fagales: Fagaceae). We investigated the interactions between the gall wasp D. kuriphilus, a native parasitoid, Ormyrus labotus (Hymenoptera: Ormyridae), and a non-native parasitoid, Torymus sinensis (Hymenoptera: Torymidae). Galls were collected monthly from May to August and in January from four locations in the United States consisting of orchard-grown hybrid chestnuts (Hiram, OH and Meadowview, VA), suburban-grown ornamental Chinese chestnuts (C. mollissima) (Broadview Heights, OH), or forest-grown American chestnuts (C. dentata) (Bowling Green, KY). Parasitoids were removed from galls and T. sinensis and O. labotus were identified using PCR-markers. The relative abundance of each parasitoid was compared in relation to collection date, habitat, presence of alternative hosts, and gall characteristics. T. sinensis was collected from each location and date, and was dominant in the orchard and suburban locations. However, relatively more O. labotus were collected within the forest, which had significant oak component and alternative cynipid hosts. O. labotus was only collected in spring and early summer, indicating the use of different summer and winter hosts. Observations suggest that in addition to parasitizing D. kuriphilus, O. labotus hyperparasitizes T. sinensis. T. sinensis has a longer ovipositor than O. labotus, and parasitized larger galls. This study improves our understanding of interactions between an invasive gall wasp, an introduced parasitoid, and native parasitoids, and illustrates novel relationships that may form as exotic species expand their geographic range.

AB Poultry (Gallus gallus domesticus L.) litter (PL) is a readily available nutrient source for crop production in the Southeast USA. Long-term PL application may alter availability of N and the effect may be dependent on tillage practice. Tillage [no till (NT) vs. conventional (CT)] and N source (PL vs. commercial fertilizer CF) effects on N availability and plant uptake were evaluated in years 9, 10, and 11 of a long-term cropping systems study at the United States Department of Agriculture, Agricultural Research Service, J. Phil Campbell Sr. Natural Resource Conservation Center, Watkinsville, GA, USA. Mineral N in the top 10 cm, measured in situ, varied each year and was influenced by time, tillage, and N source. In 2003 (year 9), soil mineral N content was greater in CT-CF (100 kg ha(-1)) than in NT-PL (95 kg ha(-1)) but in 2004 (year 10) and 2005 (year 11) it was lower in CT-CF (93 and 60 kg ha(-1)) compared to NT-PL (140 and 71 kg ha(-1)). Nitrogen mineralization rates were generally greater for PL than for CF treatments with the difference being almost 1 kg ha(-1) day(-1) in 2003. Mineralization rates were greater for NT-PL compared to CT-CF in 2004 and 2005. Across the three growing seasons, corn (Zea mays L.) aboveground biomass was consistently greater in the NT-PL treatment than in the NT-CF and CT-CF treatments. Correlation between aboveground biomass and N mineralization was greater for PL than for CF (0.75 vs. 0.48). Patterns of N mineralization and total soil mineral N indicated that the distribution of N through the growing season more closely matched corn N demand in PL treatments. Results indicate that improved N availability through the growing season, by combining NT and PL, can result in more profitable corn production in the southeast.

AB To remain viable, populations must be resilient to both natural and human-caused environmental changes. We evaluated anthropogenic effects on spatial connections among populations of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss) (designated as threatened under the U. S. Endangered Species Act) in the lower Columbia and Willamette rivers. For several anthropogenic-effects scenarios, we used graph theory to characterize the spatial relation among populations. We plotted variance in population size against connectivity among populations. In our scenarios, reduced habitat quality decreased the size of populations and hydropower dams on rivers led to the extirpation of several populations, both of which decreased connectivity. Operation of fish hatcheries increased connectivity among populations and led to patchy or panmictic populations. On the basis of our results, we believe recolonization of the upper Cowlitz River by fall and spring Chinook and winter steelhead would best restore metapopulation structure to near-historical conditions. Extant populations that would best conserve connectivity would be those inhabiting the Molalla (spring Chinook), lower Cowlitz, or Clackamas (fall Chinook) rivers and the south Santiam (winter steelhead) and north fork Lewis rivers (summer steelhead). Populations in these rivers were putative sources; however, they were not always the most abundant or centrally located populations. This result would not have been obvious if we had not considered relations among populations in a metapopulation context. Our results suggest that dispersal rate strongly controls interactions among the populations that comprise salmon metapopulations. Thus, monitoring efforts could lead to understanding of the true rates at which wild and hatchery fish disperse. Our application of graph theory allowed us to visualize how metapopulation structure might respond to human activity. The method could be easily extended to evaluations of anthropogenic effects on other stream-dwelling populations and communities and could help prioritize among competing conservation measures.

AB The amphibian fungal pathogen Batrachochytrium dendrobatidis (Bd) has received considerable attention due to its role in amphibian population declines worldwide. Although many amphibian species appear to be affected by Bd, there is little information on species-specific differences in susceptibility to this pathogen. We used a comparative experimental approach to examine Bd susceptibility in 6 amphibian species from the United States. We exposed postmetamorphic animals to Bd for 30 days and monitored mortality, feeding rates, and infection levels. In all species tested, Bd-exposed animals had higher rates of mortality than unexposed (control) animals. However, we found differences in mortality rates among species even though the amount of Bd detected on the different species' bodies did not differ. Of the species tested, southern toads (Anaxyrus terrestris) and wood frogs (Lithobates sylvaticus) had the highest rates of Bd-related mortality. Within species, we detected lower levels of Bd on individuals that survived longer and found that the relationship between body size and infection levels differed among species. Our results indicate that, even under identical conditions, amphibian species differ in susceptibility to Bd. This study represents a step toward identifying and understanding species variation in disease susceptibility, which can be used to optimize conservation strategies.

AB Outbreaks of non-target pests associated with transgenic Bt cotton threaten the economic and ecological benefits of the technology in cotton-producing countries. In the southeastern USA, stink bug pests, namely Nezara viridula L. and Euschistus servus Say (both Heteroptera: Pentatomidae), have recently become severe problems associated with Bt cotton, requiring continued insecticide use. However, the causes of non-target pest outbreaks remain unclear. Release from competition with Bt-susceptible pest species, in addition to other mechanisms, may contribute to increased stink bug populations in Bt cotton. We investigated the competitive interactions between the two stink bug species and the Bt-susceptible pests Helicoverpa zea (Boddie) and Heliothis virescens Fabricius (both Lepidoptera: Noctuidae) on non-Bt cotton. We tested for competition effects on stink bug growth rates in no-choice experiments at two spatial scales: a single cotton boll and a branch with multiple developing bolls. Although caterpillars of the two species had equivalent effects on resource availability, they had distinct effects on stink bug growth rates. Fourth instar H. zea reduced growth rates of both stink bug species by 60% when caged on a single cotton boll and reduced growth rates of only E. servus by 36% when caged on a cotton branch. In contrast, H. virescens had no effect on stink bug growth rates. Resource competition was apparent in the interactions between H. zea and E. servus, but interference competition may have contributed to the interactions as well. Competitive release of stink bug populations in Bt cotton is possible, and should be more likely for E. servus than for N. viridula. Understanding the causes of non-target pest outbreaks in Bt cotton will contribute to improved environmental risk assessments of future releases of Bt cotton and related transgenic crops.

AB The aim of this paper was to measure the broadband dielectric properties of sawdust. Knowledge of dielectric properties is important in improving understanding of a material and can lead to the development of methods for determining physical properties such as moisture and salt content. The broadband dielectric properties of sawdust were measured with an open-ended coaxial-line dielectric probe. Measurements on granular materials with the dielectric probe are dependent on the density of the measured region, which may differ from the average density of the sample. In this paper, a method was developed for determining the actual density for measurements with the dielectric probe. It consists of measurement of the dielectric constant with a different method (in this instance, a free-space transmission method) at a frequency common to both methods and identifying a relationship between the measured dielectric constant and density. The dielectric properties of sawdust samples with moisture content levels between 13% and 45% are presented for frequencies between 0.5 and 15 GHz.

AB Even though peripheral circadian oscillators in the cardiovascular system are known to exist, the daily rhythms of the cardiovascular system are mainly attributed to autonomic or hormonal inputs under the control of the central oscillator, the suprachiasmatic nucleus (SCN). In order to examine the role of peripheral oscillators in the cardiovascular system, we used a transgenic mouse where the Clock gene is specifically disrupted in cardiomyocytes. In this cardiomyocyte-specific CLOCK mutant (CCM) mouse model, the circadian input from the SCN remains intact. Both CCM and wild-type (WT) littermates displayed circadian rhythms in wheel-running behavior. However, the overall wheel-running activities were significantly lower in CCM mice compared to WT over the course of 5 weeks, indicating that CCM mice either have lower baseline physical activities or they have lower physical adaptation abilities because daily wheel running, like routine exercise, induces physical adaptation over a period of time. Upon further biochemical analysis, it was revealed that the diurnal oscillations of phosphorylation states of several kinases and protein expression of the L-type voltage-gated calcium channel (L-VGCC) alpha 1D subunit found in WT hearts were abolished in CCM hearts, indicating that in mammalian hearts, the daily oscillations of the activities of these kinases and L-VGCCs were downstream elements of the cardiac core oscillators. However, the phosphorylation of p38 MAPK exhibited robust diurnal rhythms in both WT and CCM hearts, indicating that cardiac p38 could be under the influence of the central clock through neurohormonal signals or be part of the circadian input pathway in cardiomyocytes. Taken together, these results indicate that the cardiac core oscillators have an impact in regulating circadian rhythmicities and cardiac function.

AB Environmentally hazardous and health risk substances in animals and humans in the environment have increased as a result of continuing anthropogenic activities. Examples of these activities are food processing, laboratory, food production, industrial, and other relative activities that use various forms of acrylamide. All acrylamide in the environment are manmade. It is the building block for the polymer, polyacrylamide, which is considered to be a nontoxic additive. However, if the polymerization process is not perfect and complete, the polyacrylamide may still contain acrylamide which is toxic and may pose risks and hazards to the environment. Another form of acrylamide that may pose danger as well in the environment is the acrylamide monomer, which is also a very toxic organic substance that could affect the central nervous system of humans and is likely to be carcinogenic. Phytoremediation could be a tool to somehow absorb this neurotoxic agent and lessen the contamination in the soil. This technology could lessen the soil and water contamination by acrylamide thereby limiting the exposure of animals and humans. This study may also help solve the problem of disposing contaminated acrylamide waste materials. This study was conducted to achieve the following objectives: (1) to evaluate phytoremediation potentials of some selected tropical plants in acrylamide-contaminated soil, (2) to compare the performance of tropical plants in absorbing acrylamide through accumulation in their roots and shoots, and (3) to determine the outcome of acrylamide in the soil after treatment using the test plants with phytoremediation potentials.
Soil was collected from 40 sampling points (2,000 g of soil per sampling points) in a half-hectare rice field in the Philippine Rice Research Institute, Central Experiment Station, Science City of Muoz, Nueva Ecija, Philippines. This study used Mustard (Brassica juncea L.), petchay (Brassica chinensis L.), vetiver grass (Vetiveria zizanioides L.), hog weeds (Portulaca oleracea L.), snake plant (Sanseviera trifasciata Prain), and common sword fern (Nephrolepsis cordifolia L.). These plants were selected to determine their capability of removing acrylamide residues from soil with unstable polyacrylamide gel. Analysis of acrylamide concentrations in soil and plant parts were done using a gas chromatograph equipped with flame ionization detector at the Training, Research and Development, Adamson University, Manila. This study was laid out using the completely randomized design with three replications. Data were analyzed with a one-way ANOVA using PROC GLM. Duncan's multiple range test (p a parts per thousand currency signaEuro parts per thousand 0.05) was followed for the mean treatment separation and comparison.
Among the plants tested, the highest concentration of acrylamide was absorbed by the whole plant of mustard (6,512.8 mg kg(-1)) compared with pechay (3,482.7 mg kg(-1)), fern (2,015.4 mg kg(-1)), hogweeds (1,805.3 mg kg(-1)), vetiver grass (1,385.4 mg kg(-1)), and snake plants (887.5 mg kg(-1)). Results of the study regarding the acrylamide absorption of the whole plants of mustard and pechay conformed to previous findings of other studies. Two members of the Brassica family, B. juncea L. (mustard) and B. chinensis L. (pechay) were found to be effective in removing wide ranges of contaminants. Likewise, mustard obtained the highest acrylamide concentrations (mg kg(-1)) in the roots (2,372.9) and shoots (4,081.1) among the six test plants. Earlier studies showed the capability of mustard in absorbing metals. Mustard plant is known to remove large quantities of chromium, lead, copper, and nickel in soil and ethidium bromide in soil. This could be attributed to its well-developed root system. Plants with active growth of roots in soils bring more contact with the fresh areas of the soil and ions, thus, creating more likelihood of further absorption and uptake. Moreover, mustard, pechay, and fern plants had 60% survival rate while hogweeds had 80% survival rate. Snake plant and vetiver grass had 100% survival rate. All the test plants planted in soil without acrylamide had survival rate of 100%. The 100% survival rate of vetiver grass and snake plant was due to the tolerance of these plants to acrylamide. Among the six test plants, vetiver grass and snake plant had the greatest uptake of acrylamide from the soil (30.6 kg ha(-1)) and (29.4 kg ha(-1)), respectively. These plants exhibited great number and longer roots which are characteristics of excellent phytoremediator plants. Thus, vetiver grass can absorb more acrylamide due to its root's growth characteristics. These findings could be attributed to the extraordinary features of vetiver grass such as its massive and deep root system and heavy biomass including its high tolerance to extreme soil conditions like heavy metal toxicities and high metal concentration.
Results of our study proved that all the test plants are potential phytoremediators of acrylamide. However, mustard and pechay were the most effective as they absorbed the highest acrylamide concentrations in their roots, shoots, and the whole plants. On the other hand, vetiver grass and snake plant had the highest uptake of acrylamide even though these plants did not absorb the highest acrylamide concentration. Therefore, these two plants can be considered as the best phytoremediator of acrylamide because they are perennial plants with heavier biomass with long, dense and extended root system. As such, these plants are capable of absorbing acrylamide in the soil for a long period of time. As preventive measures and for application purposes, vetiver grass and snake plants could be planted along and around the wastewater treatment ponds of laboratories using polyacrylamide gel. These plants can prevent further migration of pollutants to the environment aside from making the ponds more resistant to soil erosion. Further studies are suggested to evaluate acrylamide contaminations from laboratory washing, primary treatment pond, and seepage ponds that have earth dikes. Vetiver grass and snake plants are recommended for further phytoremediation studies for longer period of time to test the reduction of acrylamide in soil. Moreover, the outcome of acrylamide accumulation in the plants is also recommended for further study in conjunction with labeled-carbon tracer to determine its effects on the plants.

AB The use of heat to inactivate foodborne pathogens is a critical control point and the most common means for assuring the microbiological safety of processed foods. A key to optimization of the heating step is defining the target pathogens' heat resistance. Sufficient evidence exists to document that insufficient cooking, reheating, and/or subsequent cooling are often contributing factors in food-poisoning outbreaks. Accordingly, the objective of thermal processing is to design sufficient heating regiments to achieve a specific lethality for foodborne pathogens in foods. The effects and interactions of temperature, pH, sodium chloride content, sodium pyrophosphate, and sodium lactate concentration are among the variables that were considered when attempting to assess the heat inactivation kinetics of Escherichia coli O157:H7, Listeria monocytogenes, Salmonella spp., and spores of non-proteolytic Clostridium botulinum. Incorporation of these multiple barriers usually increases the sensitivity of pathogens to heat, thereby reducing heat requirements and ensuring the safety of ready-to-eat food products. Complex multifactorial experiments and analysis to quantify the effects and interactions of additional intrinsic and extrinsic factors and development of ''enhanced'' predictive models are underway to ensure the microbiological safety of thermally processed foods. Predictive inactivation kinetics (thermal death) models for foodborne pathogens have been converted into an easy-to-use computer program that is available on the USDA-Eastern Regional Research Center website. These models should aid in evaluating the safety of cooked products and are being used as building blocks for microbial risk assessment.

AB Aspergillus flavus K49 secreted at least two xylanase activities when grown on a medium containing larch (wood) xylan as a sole carbon source. Enzyme activity was assayed using an agar medium containing Remazol Brilliant Blue R conjugated oat spelt xylan as substrate. Crude enzyme preparations were inhibited by Hg(+2), with an ED(50) of 17.5 mM and maximum inhibition of 83% at 50 mM. A concentrated sample of A. flavus K49 xylanase preparation was subjected to gel filtration chromatography on a P-30 column. A small protein peak coinciding with the major peak of xylanase activity was separated from the other secreted fungal proteins. An additional peak of xylanase activity was observed in fractions containing multiple fungal proteins. Analysis by denaturing sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of fractions containing the smaller molecular weight xylanase revealed a major and minor protein band in the vicinity of 14 kD. Analysis of these same fractions by acidic native PAGE revealed a single band. Confirmation of identity for the isolated xylanase was provided by isolation of a protein band from a SDS-PAGE gel, followed by trypsin digestion/analysis by tandem mass spectrometry. Comparison of the peptide library derived from this protein band with sequence data from the A. oryzae genomic data base provided a solid match with an endo-1,4-beta-xylanase, XlnA. This identification is consistent with a low molecular weight protein associated with the major xylanolytic activity. XlnA may be a highly mobile (diffusible), plant wall hemicellulose degrading factor with significant activity during plant infection.

AB A wide range of phenotypic variation was observed among neopolyploids obtained from the diploid pear cultivar 'Fertility' by in vitro colchicine treatment. The variant plantlets had alterations in leaf characteristics. Neopolyploids had significantly different ratios of leaf length to leaf width compared to the diploid control. Shoot regeneration from leaf explants and rooting ability from in vitro shoots of neopolyploids was examined. Regeneration frequencies of shoots from leaf explants of seven of the nine neopolyploids were significantly decreased compared to the diploid control. The organogenic potential of neopolyploids was highly genotype-dependent for both shoots and roots. Tetraploid clone 4x - 4 failed to regenerate shoots from leaf explants and the pentaploid clone 5x - 2 failed to root from in vitro shoots. The results suggest that polyploidization caused the decrease in or loss of in vitro organogenic potential. Regenerated shoots derived from neopolyploids showed different phenotypes, depending on the ploidy of the donor plant.

AB Environmental contamination with Mycobacterium avium subsp. paratuberculosis (MAP) is thought to be one of the primary sources of infection for dairy cattle. The exact link between fecal shedding of MAP by individual cows and environmental contamination levels at the herd level was explored with a cross-sectional analysis of longitudinally collected samples on 3 dairy farms. Composite samples from multiple environmental sites in 3 commercial dairy herds in the Northeast US were cultured quarterly for MAP, providing 1131 samples (133 (11.8%) were culture-positive), and all adult animals in the herds were tested biannually by fecal culture (FC), for 6 years. Of the environmental sites sampled, manure storage areas and shared alleyways were most likely to be culture-positive. Environmental sample results were compared to FC results from either the concurrent or previous sampling date at both the herd and the pen level. At the herd level, a 1 log unit increase in average fecal shedding increased the odds of a positive non-pen environmental sample by a factor of 6 and increased the average amount of MAP in non-pen samples by 2.9 cfu/g. At the pen level, a 1 log unit increase in average fecal shedding in the pen increased the odds of a positive environment by a factor of 2.4 and the average amount of MAP was increased by 3.5 cfu/g. We were not able to model the relationship between non-pen environmental sample status and the distance between shedding animals and the sample's location, and neighboring pens did not significantly affect the results of the pen-level analysis. The amount of MAP in pen-level samples and the probability of a pen testing positive for MAP were both positively but non-significantly correlated with the number of animals in the pen shedding >30 cfu/g of MAP. At least 6 environmental samples met the criteria for the U.S. Voluntary Bovine Johne's Disease Control Program on 47 of the 72 sampling dates; of these, 19 of the 47 FC-positive sampling dates were positive by the 6-sample environmental testing method, resulting in a herd sensitivity of 0.40 (95% Cl: 0.26-0.54). None of the 3 FC-negative sampling dates produced positive environmental samples. Although environmental sampling can be used as a tool in understanding the level of MAP infection in a herd or pen, it did not appear to be a sensitive diagnostic method for herd positivity in these low prevalence herds, and its use may require caution.

AB About 30% of the total number of gilts selected for reproduction at the large breeding farm units in Vojvodina (Republic of Serbia) are culled due to prolonged pre-insemination anoestrus (estrus not detected until 8 mo of age). The aim of this study was to provide the answer to the following question: do the culling gilts reach cyclic ovarian activity at all? One hundred seventy five culled gilts in which external estrus manifestations were not detected by 8 mo of age were sacrificed and their reproductive organs were examined for determination of sexual maturity (ovaries exhibiting pre-ovulatory follicles 8 to 11 mm in diameter, corpora hemorrhagica, corpora lutea and corpora albicantia). Uterine weights and horn length were also determined. Functional ovaries were observed in 107 (61.1%) examined gilts, with 62 animals having one and 45 having two puberty ovarian cycles (57.9% and 42.1%, respectively). Pathomorphological changes which could result in prolonged pre-insemination anoestrus were not observed on the reproductive organs of sexually mature gilts. Our results indicate that most of the culling gilts have reached cyclic ovarian activity. The main reason for culling due to the absence of external estrus manifestations in sexually mature gilts could be inadequate estrus detection technology. (C) 2011 Elsevier Inc. All rights reserved.

AB Argentina suffered an extensive foot-and-mouth disease (FMD) epidemic between July 2000 and January 2002, 3 months after obtaining the official FMD-free without vaccination status conferred by the World Organization for Animal Health. This is one of the largest FMD epidemics controlled by implementation of a systematic mass vaccination campaign in an FMD-free country. In 2000, 124 herds were reported as FMD positive, 2394 herds in 2001 and one in January 2002; the total number of cattle herds in the country at that time was approximately 230 000. Estimates of FMD transmission are important to understand the dynamics of disease spread and for estimating the value for the parameterization of disease transmission models, with the ultimate goals of predicting its spread, assessing and designing control strategies, conducting economic analyses and supporting the decision-making process. In this study, the within-herd coefficient of transmission, beta, was computed for herds affected in the 2001 FMD epidemic and categorized as low or high based on the median value of beta. A logistic regression model was fitted to identify factors significantly associated with high values of beta. Results suggested that the odds of having a high within-herd transmission were significantly associated with time from initial herd infection to disease detection, date of report, vaccination, and time from initial herd infection to herd vaccination. Results presented in this study demonstrate, in quantifiable terms, the protective impact of vaccination in reducing FMD transmission in infected herds. These results will be useful for the parameterization of epidemiological models aimed at quantifying the impact of vaccination and for the design and implementation of FMD emergency vaccination strategies in face of an epidemic.

AB Salmonella in swine is a major food safety problem, as the majority of US swine herds are Salmonella-positive. Salmonella can be shed from colonized swine and contaminate (i) neighbouring pigs; (ii) slaughter plants and pork products; (iii) edible crops when swine manure is used as a fertilizer; and (iv) water supplies if manure used as crop fertilizer runs off into streams and waterways. A potentially powerful method of addressing pre-harvest food safety at the farm level is through genetic improvement of disease resistance in animals. In this research, we describe a successful strategy for discovering genetic variation at candidate genes associated with disease resistance in pigs. This involves integrating our recent global gene expression analysis of the porcine response to Salmonella with information from the literature about important candidate genes. We identified single-nucleotide polymorphisms (SNPs) in these functional candidate genes and genotyped three independent pig populations that had data on Salmonella faecal shedding or internal burden (total n = 377) at these loci. Of 31 SNPs genotyped, 21 SNPs segregated in at least two populations with a minor allele frequency of 15% or greater. Statistical analysis revealed thirteen SNPs associated with Salmonella faecal shedding or tissue colonization, with an estimated proportion of false positives (PFP) <= 0.2. The genes with associated SNPs included GNG3, NCF2, TAP1, VCL, AMT, CCR1, CD163, CCT7, EMP1 and ACP2. These associations provide new information about the mechanisms of porcine host response to Salmonella and may be useful in improving genetic resistance to this bacterium.

AB Deposit of useful microorganisms in culture collections requires long-term preservation and successful reactivation techniques. The goal of this study was to develop a simple preservation protocol for the long-term storage and reactivation of the anammox biomass. To achieve this, anammox biomass was frozen or lyophilized at two different freezing temperatures (-60A degrees C and in liquid nitrogen (-200A degrees C)) in skim milk media (with and without glycerol), and the reactivation of anammox activity was monitored after a 4-month storage period. Of the different preservation treatments tested, only anammox biomass preserved via freezing in liquid nitrogen followed by lyophilization in skim milk media without glycerol achieved stoichiometric ratios for the anammox reaction similar to the biomass in both the parent bioreactor and in the freshly harvested control treatment. A freezing temperature of -60A degrees C alone, or in conjunction with lyophilization, resulted in the partial recovery of the anammox bacteria, with an equal mixture of anammox and nitrifying bacteria in the reactivated biomass. To our knowledge, this is the first report of the successful reactivation of anammox biomass preserved via sub-zero freezing and/or lyophilization. The simple preservation protocol developed from this study could be beneficial to accelerate the integration of anammox-based processes into current treatment systems through a highly efficient starting anammox biomass.

AB Questions: Can we use plant traits to make predictions about ecosystem functioning of different species mixtures, identify inherent trade-offs of particular species, and design custom communities for desired ecosystem functions? Can we develop a methodology to address plant trait-functioning relationships in species-level units, which are missing from measures of community functional diversity but needed for management?
Location: Grazing lands northeastern USA.
Method: We measured 53 physiological, morphological and growth traits for 19 plant species from glasshouse and field experiments. We developed a two-step method to link species to ecosystem processes related to management goals of improving desirable forage production in grazing lands in northeastern USA.
Results: Species were distributed continuously, rather than clustering into discrete functional types. Grasses, legumes and forbs overlapped considerably in trait values with these common classifications failing to adequately distinguish functional differences. Factor analyses were used to assess variation in species traits, and to rate species for six plant processes through which species contribute to the production of desirable forage. Species performed well in some processes and poorly in others, illustrating complex trade-offs.
Conclusions: This methodology provides a foundation for developing tools to guide construction of communities for applied settings, and for assembling hypotheses about plant functioning in mixtures.

AB Alternative protein sources for aquafeeds need to be indentified in order to increase the efficiency of production. Many studies have examined terrestrial plant meals/protein concentrates as alternatives. Recently the focus has turned to aquatic protists and plants as well as by-products from other industries, such as breweries. Atlantic salmon, Salmo salar, and Arctic charr, Salvelinus alpinus, were fed diets containing canola meal, soybean meal, corn gluten meal, soy protein concentrate, barley protein concentrate, and solar dried algae included at 30% of the test diet. Barley protein concentrate had the highest apparent protein digestibility values for both species (96.3% for Atlantic salmon and 85.1% for Arctic charr), followed by corn gluten meal. Algae had the highest organic matter digestibility value for arctic charr (80.1%) while corn gluten meal had the highest organic matter digestibility value for Atlantic salmon (88.4%). Algae had a high energy apparent digestibility coefficient (82.4 salmon, 82.7 charr) along with corn gluten meal (78.5 salmon, 82.7 charr) for both species. In general, Atlantic salmon had higher apparent digestibility coefficients compared to Arctic charr for most of the tested ingredients. Both corn gluten and barley protein concentrate appear good candidates as alternative protein sources with both species.

ID FOREST LANDSCAPE; MYOTIS-LUCIFUGUS; PATTERNS
AB White-nose syndrome (WNS) was first reported in a hibernating bat population in central New York State in February 2006. Since 2006, WNS has been reported from bat hibernacula across much of eastern United States and adjacent Canada and has been associated with a dramatic decline in the populations of hibernating bats in the northeastern U.S. We are only beginning to discover how these declines are manifest in changes in summer bat abundance and activity at local scales. A 3-year (2004-2006) acoustic survey showed that the forested watershed of the Quabbin Reservoir in central Massachusetts supported an abundant and species-rich summer bat community. In 2010, 4-years following the initial occurrence of WNS, a re-survey of the same habitats and sites found a 72% reduction in bat activity on the watershed. This is the identical rate of decline reported from cave hibernacula surveys (73%). This decline in summer activity levels is most likely a consequence of WNS-caused mortality. The impacts of population losses of this magnitude of a once widespread and abundant taxa are unknown but are presumed to be ecologically significant.

AB Beaver (Castor canadensis) are currently the focus of many wetland restoration projects as a keystone species and an ecosystem engineer. This species forms multi-season pair bonds, making sex ratio an especially important consideration for restoration projects. However, beavers lack external sexual dimorphism (with the exception of lactation) and current methods of sex identification have error rates a parts per thousand yen10%. We improved on previous methods of genetic sex identification for beaver by developing a test that uses a short nuclear fragment in addition to an established Y chromosome-specific sex-determining region (SRY) marker. This method had 100% accuracy with 28 known-sex samples and 95% PCR success with no inconsistencies for 42 hair samples from beavers of unknown sex. We used this test to inform a beaver restoration study and increase the probability of population establishment from translocated animals.

AB Field experiments were conducted at the U.S. Vegetable Laboratory, Charleston, SC, U.S.A in 2000, 2001, and 2004 to assess the effect of different durations of weed interference on two sweet potato cultivars with different shoot growth habits. The cultivars were Beauregard, which has a spreading growth habit that is typical of U.S. sweet potato cultivars and Carolina Bunch, with an erect growth habit. Weed interference treatments included control plots that were maintained weed free throughout the growing season and plots that were maintained weed free for 0,10, 20, and 30 days after transplanting. In general, Carolina Bunch was more tolerant of weed interference than was Beauregard. In two of three years Carolina Bunch storage root yields were higher than Beauregard yields in plots that received no weeding; whereas, yields of the two cultivars in weed free plots were not different. Weed interference affected shoot growth to a greater extent than it affected storage root production. At the end of the growing season, Carolina Bunch shoot biomass was greater than Beauregard shoot biomass in plots receiving no weeding and in plots that were maintained weed free for 10 days in all three years. Shoot biomasses of the two cultivars were not different in weed-free plots. Weed shoot biomasses were greater in Beauregard plots than in Carolina Bunch plots in several instances. These results demonstrate that sweet potato cultivars with a vigorous, erect shoot growth habit (with shorter stems, greater branching, and a denser and taller canopy early in the growing season) may be less susceptible to weed interference than cultivars with spreading shoot growth. This study also confirmed previous observations that sweet potato productivity is not greatly affected by moderate weed interference: thus, it may not require intense weed management to produce high yields.

DE Emamectin benzoate; Photodegradation; UV light; Chilo suppressalis
ID SOILS
AB Emamectin benzoate, a novel insecticide with characteristics of translaminar movement into plant leaf tissue, was derived from the avermectin family with improved thermal stability, greater water solubility and a broader spectrum of insecticidal activity than avermectin. To quantify UV photodegradation of emamectin benzoate, HPLC analysis was conducted to quantify residues of MAB1a, the major component in emamectin benzoate, after exposure to UV light for different lengths of time. Results showed both MAB1a concentration and length of UV light exposure (0-120 h) had significant impacts on photodegradation rate. The degradation rate increased as exposure duration increased, but decreased as initial MAB1a concentration increased. Four UV protectants, kojic acid, sodium ligninsulfonate, soybean lecithin and milk, were evaluated for their effect on UV degradation. Results showed that kojic acid could effectively reduce the photodegradation of MAB1a. In addition, the photodegradation of emamectin benzoate was also examined for its influence on the efficacy against the rice stem borer, Chilo suppressalis. The results of the bioassays were consistent with those of HPLC analysis. The initial concentration of emamectin benzoate and exposure duration to UV light both had significant influences on the efficacy against C. suppressalis. As the UV exposure time increased, the efficacy of emamectin benzoate against C. suppressalis decreased. The results indicated that UV photodegradation has a significant effect on the efficacy of emamectin benzoate against C. suppressalis and the effect is concentration-dependant. In addition to understanding the critical factor of UV exposure length, this study also showed that maintaining emamectin benzoate concentration above a certain level in the formulation and the application solution, and applying UV protectants may reduce photodegradation and increase efficacy against target pests.

AB Rural areas represent approximately 95% of the 14000 km(2) Alabama Black Belt, an area of widespread Vertisols dominated by clayey, smectitic, shrink-swell soils. These soils are unsuitable for conventional onsite wastewater treatment systems (OWTS) which are nevertheless widely used in this region. In order to provide an alternative wastewater dosing system, an experimental field moisture controlled subsurface drip irrigation (SDI) system was designed and installed as a field trial. The experimental system that integrates a seasonal cropping system was evaluated for two years on a 500-m(2) Houston clay site in west central Alabama from August 2006 to June 2008. The SDI system was designed to start hydraulic dosing only when field moisture was below field capacity. Hydraulic dosing rates fluctuated as expected with higher dosing rates during warm seasons with near zero or zero dosing rates during cold seasons. Lower hydraulic dosing in winter creates the need for at least a two-month waste storage structure which is an insurmountable challenge for rural homeowners. An estimated 30% of dosed water percolated below 45-cm depth during the first summer which included a 30-year historic drought. This massive volume of percolation was presumably the result of preferential flow stimulated by dry weather clay soil cracking. Although water percolation is necessary for OWTS, this massive water percolation loss indicated that this experimental system is not able to effective control soil moisture within its monitoring zone as designed. Overall findings of this study indicated that soil moisture controlled SDI wastewater dosing is not suitable as a standalone system in these Vertisols. However, the experimental soil moisture control system functioned as designed, demonstrating that soil moisture controlled SDI wastewater dosing may find application as a supplement to other wastewater disposal methods that can function during cold seasons.

AB The microbial insecticide Bacillus thuringiensis (Bt) produces Cry toxins, proteins that bind to the brush border membranes of gut epithelial cells of insects that ingest it, disrupting the integrity of the membranes, and leading to cell lysis and insect death. In gypsy moth, Lymantria dispar, two toxin-binding molecules for the Cry1A class of Bt toxins have been identified: an aminopeptidase N (APN-1) and a 270 kDa anionic glycoconjugate (BTR-270). Studies have shown that APN-1 has a relatively weak affinity and a very narrow specificity to Cry1Ac, the only Cry1A toxin that it binds. In contrast, BTR-270 binds all toxins that are active against L dispar larvae, and the affinities for these toxins to BTR-270 correlate positively with their respective toxicities. In this study, an immunohistochemical approach was coupled with fluorescence microscopy to localize APN-1 and BTR-270 in paraffin embedded midgut sections of L. dispar larvae. The distribution of cadherin and alkaline phosphatase in the gut tissue was also examined. A strong reaction indicative of polyanionic material was detected with alcian blue staining over the entire epithelial brush border, suggesting the presence of acidic glycoconjugates in the microvillar matrix. The Cry1A toxin-binding sites were confined to the apical surface of the gut epithelial cells with intense labeling of the apical tips of the microvilli. APN-1, BTR-270, and alkaline phosphatase were found to be present exclusively along the brush border microvilli along the entire gut epithelium. In contrast, cadherin, detected only in older gypsy moth larvae, was present both in the apical brush border and in the basement membrane anchoring the midgut epithelial cells. The topographical relationship between the Bt Cry toxin-binding molecules BTR-270 and APN-1 and the Cry1A toxin-binding sites that were confined to the apical brush border of the midgut cells is consistent with findings implicating their involvement in the mechanism of the action of Bt Cry toxins.

AB The entomopathogenic fungus Metarhizium anisopliae and sister species are some of the most widely used biological control agents for insects. Availability of specific monitoring and quantification tools are essential for the investigation of environmental factors influencing their environmental distribution. Naturally occurring as well as released Metarhizium strains in the environment traditionally are monitored with cultivation-dependent techniques. However, specific detection and quantification may be limited due to the lack of a defined and reliable detection range of such methods. Cultivation-independent PCR-based detection and quantification tools offer high throughput analyses of target taxa in various environments. In this study a cultivation-independent PCR-based method was developed, which allows for specific detection and quantification of the defined Metarhizium clade 1, which is formed by the species Metarhizium majus, Metarhizium guizhouense, Metarhizium pingshaense, Metarhizium anisopliae, Metarhizium robertsii and Metarhizium brunneum, formerly included in the M. anisopliae cryptic species complex. This method is based on the use of clade-specific primers, i.e. Ma 1763 and Ma 2097, that are positioned within the internal transcribed spacer regions 1 and 2 of the nuclear ribosomal RNA gene cluster, respectively. BLAST similarity searches and empirical specificity tests performed on target and non-target species, as well as on bulk soil DNA samples, demonstrated specificity of this diagnostic tool for the targeted Metarhizium clade 1. Testing of the primer pair in qPCR assays validated the diagnostic method for specific quantification of Metarhizium clade 1 in complex bulk soil DNA samples that significantly correlated with cultivation-dependent quantification. The new tool will allow for highly specific and rapid detection and quantification of the targeted Metarhizium clade 1 in the environment. Habitat with high Metarhizium clade 1 densities can then be analyzed for habitat preferences in greater detail using cultivation-dependent techniques and genetic typing of isolates.

AB Consumption of industrially produced trans fatty acids (IP-TFA) has been positively associated with systemic markers of low-grade inflammation and endothelial dysfunction in cross-sectional studies, but results from intervention studies are inconclusive. Therefore, we conducted a 16 week double-blind parallel intervention study with the objective to examine the effect of IP-TFA intake on bio-markers of inflammation, oxidative stress, and endothelial dysfunction. Fifty-two healthy overweight postmenopausal women (49 completers) were randomly assigned to receive either partially hydrogenated soybean oil (15.7 g/day IP-TFA) or control oil without IP-TFA. After 16 weeks, IP-TFA intake increased baseline-adjusted serum tumor necrosis factor (TNF) alpha by 12% [95% confidence interval (CI): 5-20; P = 0.002] more in the IP-TFA group compared with controls. Plasma soluble TNF receptors 1 and 2 were also increased by IP-TFA [155 pg/ml (CI: 63-247); P < 0.001 and 480 pg/ml (CI: 72-887); P = 0.02, respectively]. Serum C-reactive protein, interleukin (IL) 6 and adiponectin and subcutaneous abdominal adipose tissue mRNA expression of IL6, IL8, TNF alpha, and adiponectin as well as ceramide content were not affected by IP-TFA, nor was urinary 8-iso-prostaglandin-F-2 alpha. In conclusion, this dietary trial indicates that the mechanisms linking dietary IP-TFA to cardiovascular disease may involve activation of the TNF alpha system.-Bendsen, N. T., S. Stender, P. B.

AB Seed-borne pathogens pose a serious threat to modern agricultural cropping systems, as they can be disseminated to many geographical regions around the world. With trends of increasing global seed production and trade, seed-health testing is an important quality control step to prevent the introduction of harmful pathogens into agricultural production systems. An effective seed-health assay depends on a test that can provide timely, sensitive and broad-spectrum detection of all genetic variants of a pathogen, or in some cases, of several different pathogens. Previously, we developed a real-time PCR (qPCR) assay that would permit the simultaneous detection of two major seed-borne pathogens of cucurbits, the bacterium Acidovorax avenae subsp. citrulli (AAC, the causal agent of bacterial fruit blotch) and a fungus Didymella bryoniae (DB, the causal agent of gummy stem blight). The objective of the present study was to develop a sensitive, reverse transcriptase (RT)-based, qRT-PCR for broad spectrum detection of both serotypes of Squash mosaic virus (SqMV), that could be incorporated into a simultaneous detection of three pathogen types in a single PCR reaction. Converting SqMV RNA to cDNA prior to multiplexing stabilized the viral template that was then mixed with two other DNA templates (AAC and DB). To facilitate seed health testing, a generic plant nucleic acid extraction method was developed for cucurbit seeds. Using this method, nucleic acids extracted from seeds yielded strong signals for each target pathogen in multiplex qPCR. The ability to use a general nucleic acid extraction technique with subsequent PCR to detect bacterial, fungal and viral plant pathogens lends itself to a universal system for cucurbit seed health testing.

ID SEED OIL; OILSEEDS; QUALITY
AB Modification of cottonseed quality traits is likely to be achieved through a combination of genetic modification, manipulation of nutrient allocation, and selective breeding. Oil and protein stores account for the majority of mass of cottonseed embryos. A more comprehensive understanding of the relationship between lint quality, lint yield, and embryo reserve accumulation will assist breeders in their efforts to improve seed value. Here we report the development of a rapid, nondestructive, simultaneous method for quantifying oil and protein levels within cottonseed by low-field (1)H time-domain nuclear magnetic resonance (TD-NMR). This approach is suitable for a minimal amount of seed and represents an accurate (oil R (2) = 0.998, protein R (2) = 0.95), noninvasive alternative to conventional, time-consuming chemical extractions. We demonstrate the value of this approach by surveying seed reserve content, identifying extremes of either protein and/or oil, in two sets of diverse germplasm.

We report on a case of primary cutaneous mucormycosis, involving the forearms of a cotton farmer from North Carolina, in which the infection was cured using amphotericin B therapy. Intraspecific crosses between the North Carolina strain DUMC 150.04 and M. irregularis CBS 103.93, the ex-type strain of R. variabilis var. variabilis from China, resulted in the formation of abundant fertile zygospores. By way of contrast, interspecific crosses between the North Carolina isolate and the ex-neotype strain of M. hiemalis NRRL 3624 resulted in the formation of putative azygospores by M. irregularis DUMC 150.04.

AB Microarray technology was used to identify the genes associated with disease defence responses in the model legume Medicago truncatula. Transcript profiles from M. truncatula cv. Jemalong genotype A17 leaves inoculated with Colletotrichum trifolii and Erysiphe pisi and roots infected with Phytophthora medicaginis were compared to identify the genes expressed in response to all three pathogens and genes unique to an interaction. The A17 genotype is resistant to C. trifolii and E. pisi, exhibiting a hypersensitive response after inoculation, and is moderately susceptible to P. medicaginis. Among the most strongly up-regulated genes in all three interactions were those encoding a hevein-like protein, thaumatin-like protein (TLP) and members of the pathogenesis response (PR) 10 family. Transcripts of genes for enzymes in the phenylpropanoid pathway leading to the production of isoflavonoid phytoalexins increased dramatically in response to inoculation with the foliar pathogens. In P. medicaginis-inoculated roots, transcripts of genes in the phenylpropanoid pathway peaked at 5 days post-inoculation, when symptoms became visible. Transcript accumulation of three PR10 family members, a TLP and chalcone synthase (CHS) was assessed in M. truncatula genotype R108 plants. The R108 plants are resistant to C. trifolii and moderately susceptible to E. pisi and P. medicaginis. Transcript accumulation paralleled the stages of pathogen development. To evaluate the role of a TLP, a PR10 family member and CHS in disease resistance, transgenic R108 plants containing interfering RNA (RNAi) constructs were produced. Reduced expression of PR10 and TLP had no effect on the disease phenotype, whereas reduced expression of CHS resulted in increased susceptibility to necrotrophic pathogens.

AB The present study is aimed at quantifying the flame radiosity vertical profile and gas temperature in moderate to high intensity spreading fires in shrubland fuels. We report on the results from 11 experimental fires conducted over a range of fire rate of spread and frontal fire intensity varying respectively between 0.04-0.35 m s(-1) and 468-14,973 kW m(-1). Flame radiosity, or radiant emissive power, and gas temperatures were measured with narrow angle radiometers and fine wire thermocouples located at three different heights in the flames, 0.6, 1.1 and 1.6 m above ground. Measured peak radiosity within the visual flame region (reaction zone and free flame) varied between 41 and 176 kW m(-2). Measurements within the intermittent flame region above the visually estimated average flame height varied between 10 and 30 kW m(-2). The flame vertical radiometric profile was characterized by a uniform area within the reaction zone and lower free flame, and a decrease in radiosity with height as the measurements approach the flame tip.

In September 2009, two greenhouses in the Alfaro Ruiz region, northwest of the country's capital, San Jose, were surveyed as part of a larger effort to determine the occurrence of species and races of whiteflies in this agronomically important region. In addition, the insect samples were analyzed to determine the presence of Tomato chlorosis virus (ToCV), a yield-affecting crinivirus transmitted by whiteflies. The results revealed the presence of the Q biotype of B. tabaci, and important invasive species, as well as the expected T. vaporariorum. Viral detection assays identified potentially viruliferous individuals for Tomato chlorosis virus. These results identified a new pest capable of harbouring plant viruses has been identified, as well as a viral agent (ToCV) in a region where it was not reported, and which might cause significant yield losses.

AB Rhizoctonia spp. anastomosis groups (AGs) associated with canola and lupin in the southern and western production areas of the Western Cape province of South Africa were recovered during the 2006 and 2007 growing seasons and identified using sequence analyses of the rDNA internal transcribed spacer regions. The effect of crop rotation systems and tillage practices on the recovery of Rhizoctonia spp. was evaluated at Tygerhoek (southern Cape, Riviersonderend) and Langgewens (western Cape, Moorreesburg) experimental farms. Isolations were conducted from canola planted after barley, medic/clover mixture and wheat, and lupin planted after barley and wheat, with sampling at the seedling, mid-season and seedpod growth stages. In the 2006 study, 93.5% of the Rhizoctonia isolates recovered were binucleate and 6.5% multinucleate; in 2007, 72.8% were binucleate and 27.2% were multinucleate. The most abundant AGs within the population recovered included A, Bo, I and K, among binucleate isolates and 2-1, 2-2 and 11 among multinucleate isolates. Crop rotation sequence, tillage and plant growth stage at sampling all affected the incidence of recovery of Rhizoctonia, but certain effects were site-specific. The binucleate group was more frequently isolated from lupin and the multinucleate group from canola. AG-2-1 was only isolated from canola and AG-11 only from lupin. This study showed that important Rhizoctonia AGs such as AG-2-1, 2-2 and 11 occur in both the southern and the western production areas of the Western Cape province and that crop rotation consistently influences the incidence and composition of the Rhizoctonia community recovered from the cropping system.

AB Soil temperatures at 15A degrees C or below limit germination and seedling establishment for warm season cereal crops such as sorghum (Sorghum bicolor (L.) Moench) during early-season planting. To better understand the genetics of early-season cold tolerance in sorghum, mapping of quantitative trait loci (QTL) associated with germination, emergence and vigor using a recombinant inbred mapping population was carried out. A mapping population consisting of 171 F(7)-F(8) recombinant inbred lines (RILs) derived from the cross between RTx430 (cold-sensitive) and PI610727 (cold-tolerant) was developed and a genetic map was constructed using 141 microsatellites or simple sequence repeat (SSR) markers. The RILs were evaluated for cold and optimal temperature germinability in the laboratory, field emergence, and seedling vigor in two locations during early-season planting. Two or more QTL were detected for all traits, except for seedling vigor, with only one QTL was detected in the population. A QTL for cold germinability (Germ 12-2.1) showed the highest LOD value and was also associated with optimal germinability. One of the QTL for field emergence, Fearlygerm-9.3, a contribution from PI610727, was found significant in both locations used for the study. This study showed alignment of QTL in SBi1 (Fearlygerm-1.2 and FGerm30-1.2) with previously reported QTL associated with late field emergence identified from a different mapping population. This indicates that PI617027 shares some common loci with other known early-season cold-tolerant sorghum germplasm but also harbors novel QTL that could be useful in introgression of enhanced laboratory germination and early-season field emergence.

ID PRESSURE
AB Time constraints, like money constraints, affect Americans' well-being. This paper defines what it means to be time poor based on the concepts of necessary and committed time and presents time poverty thresholds and rates for the US population and certain subgroups. Multivariate regression techniques are used to identify the key variables associated with discretionary time and time poverty. The data confirm the idea that individuals in households with children have less discretionary time and are thus more likely to be time poor than those in households without children. Controlling for other household characteristics, an additional child reduces a household adult's daily discretionary time by 35 min. Surprisingly, while one might expect the necessary and committed activities required of an individual to be less in a two-adult household with children than in a one-adult household with children because child care can be shared, the data show that the presence of such a second adult only marginally reduces the necessary and committed time burden of an individual household member. Perhaps even more surprisingly, household income is not a statistically significant correlate of discretionary time or time poverty.

AB The synthesis of hydroxylated and O- or N-dealkylated human drug metabolites (HDMs) via selective monooxygenation remains a challenging task for synthetic organic chemists. Here we report that aromatic peroxygenases (APOs; EC 1.11.2.1) secreted by the agaric fungi Agrocybe aegerita and Coprinellus radians catalyzed the H(2)O(2)-dependent selective monooxygenation of diverse drugs, including acetanilide, dextrorphan, ibuprofen, naproxen, phenacetin, sildenafil and tolbutamide. Reactions included the hydroxylation of aromatic rings and aliphatic side chains, as well as O- and N-dealkylations and exhibited different regioselectivities depending on the particular APO used. At best, desired HDMs were obtained in yields greater than 80% and with isomeric purities up to 99%. Oxidations of tolbutamide, acetanilide and carbamazepine in the presence of H(2)(18)O(2) resulted in almost complete incorporation of (18)O into the corresponding products, thus establishing that these reactions are peroxygenations. The deethylation of phenacetin-d(1) showed an observed intramolecular deuterium isotope effect [(k(H)/k(D))(obs)] of 3.1 +/- 0.2, which is consistent with the existence of a cytochrome P450-like intermediate in the reaction cycle of APOs. Our results indicate that fungal peroxygenases may be useful biocatalytic tools to prepare pharmacologically relevant drug metabolites. (C) 2011 Elsevier Inc. All rights reserved.

AB Historical land use and management practices in the southeastern United States have resulted in the dominance of loblolly pine (Pin us taeda L.) on many upland sites that historically were occupied by longleaf pine (Pinus palustris Mill.). There is currently much interest in restoring high quality longleaf pine habitats to such areas, but managers may also desire the retention of some existing canopy trees to meet current conservation objectives. However, fast-growing natural loblolly pine regeneration may threaten the success of artificially regenerated longleaf pine seedlings. We evaluated the establishment and growth of natural loblolly pine regeneration following different levels of timber harvest using single-tree selection (Control (uncut, residual basal area similar to 16 m(2)/ha), MedBA (residual basal area of similar to 9 m(2)/ha). LowBA (residual basal area of similar to 6 m(2)/ha), and Clearcut (complete canopy removal)) and to different positions within canopy gaps (approximately 2800 m(2)) created by patch cutting at two ecologically distinct sites within the longleaf pine range: Fort Benning, GA in the Middle Coastal Plain and Camp Lejeune, NC in the Lower Coastal Plain. The density of loblolly pine seedlings was much higher at Camp Lejeune than at Fort Benning at the end of the first growing season after harvesting. Following two growing seasons, there were no significant effects of canopy density or gap position on the density of loblolly pine seedlings at either site, but loblolly pine seedlings were taller on treatments with greater canopy removal. Prescribed fires applied following the second growing season killed 70.6% of loblolly pine seedlings at Fort Benning and 64.3% of seedlings at Camp Lejeune. Loblolly pine seedlings were generally less than 2 m tall, and completeness of the prescribed burns appeared more important for determining seedling survival than seedling size. Silvicultural treatments that include canopy removal, such as patch cutting or clearcuts, will increase loblolly pine seedling growth and shorten the window of opportunity for control with prescribed fire. Therefore, application of prescribed fire every 2-3 years will be critical for control of loblolly pine regeneration during restoration of longleaf pine in existing loblolly pine stands.

AB During the past few decades, China has implemented several large-scale forestation programs that have increased forest cover from 16.0% in the 1980s to 20.4% in 2009. In northern China, water is the most sensitive and limiting ecological factor. Understanding the dynamic interactions between forest ecosystems and water in different regions is essential for maximizing forest ecosystem services. We examined forest cover and runoff relationships in northern China using published data from a variety of sources. In the Loess Plateau region, forest cover is not correlated with annual precipitation (r = 0.08, p > 0.05) at micro (<50 km(2)) and meso scales (50-1000 km(2)), while they are positively correlated at macro (>1000 km(2)) scale (r = 0.77, p < 0.05). Moreover, forest cover is negatively correlated with the runoff coefficient (r = -0.64, p < 0.05). In Northwest China, natural forest distribution is highly correlated with annual precipitation (r = 0.48, p < 0.05) but not with the runoff coefficient (r = -0.09, p > 0.05). In Northeast China, we found a positive relationship between forest cover and the runoff coefficient (r = 0.77, p < 0.05), but the correlation between forest cover and precipitation was not significant (r = 0.28, p > 0.05). The multiple stepwise regression analysis indicated that runoff was influenced by altitude, annual precipitation, forest cover, and PET (potential evapotranspiration) in Northeast China. We concluded that geographic differences could mask the true role of forests in the partitioning of rainfall into runoff and evapotranspiration (ET) in a catchment. In determining the forest-water relationship, one must consider climatic controls on ET in addition to forest cover. Forests could potentially enhance the complementary relationship between ET and PET. Therefore, a greater amount of ET in forested areas may decrease the PET on a regional scale.

AB Use of herbicides in forestry to direct successional trajectories has raised concerns over possible direct or indirect effects on non-target organisms. We studied the response of forest birds to an operational application of glyphosate and sulfometuron methyl herbicides, using a randomized block design in which half of each 8 ha block received herbicide and the other acted as a control, on shelterwood seed-cut Allegheny hardwood stands in northwestern Pennsylvania. We monitored birds using 50 m radius point counts in two pretreatment years and for 10 years post-treatment (1992-2004). Fences were erected six years after herbicide treatment in response to increased deer browsing at a subset of sites. Avian responses to herbicide treatment varied by nesting guild: we detected no response by cavity-nesters, but documented declines in the shrub-, ground- and canopy-nesting guilds. Responses were short-lived (2-4 years post-treatment), but shrub-nesters did not recover until fencing provided regenerating vegetation respite from browsing. Thus, apparent responses of birds to herbicide were confounded with deer browsing in this study. High species turnover, even within control plots, suggests that avian communities may be assessed more appropriately assessed at larger spatial scales than those used in this study (6.5-8 ha).

AB Carbon sequestration is increasingly recognized as an ecosystem service, and forest management has a large potential to alter regional carbon fluxes - notably by way of harvest removals and related impacts on net ecosystem production (NEP). In the Pacific Northwest region of the US, the implementation of the Northwest Forest Plan (NWFP) in 1993 established a regional socioecological system focused on forest management. The NWFP resulted in a large (82%) decrease in the rate of harvest removals on public forest land, thus significantly impacting the regional carbon balance. Here we use a combination of remote sensing and ecosystem modeling to examine the trends in NEP and net ecosystem carbon balance (NECB) in this region over the 1985-2007 period, with particular attention to land ownership since management now differs widely between public and private forestland. In the late 1980s, forestland in both ownership classes was subject to high rates of harvesting, and consequently the land was a carbon source (i.e. had a negative NECB). After the policy driven reduction in the harvest level, public forestland became a large carbon sink - driven in part by increasing NEP - whereas private forestland was close to carbon neutral. In the 2003-2007 period, the trend towards carbon accumulation on public lands continued despite a moderate increase in the extent of wildfire. The NWFP was originally implemented in the context of biodiversity conservation, but its consequences in terms of carbon sequestration are also of societal interest. Ultimately, management within the NWFP socioecological system will have to consider trade-offs among these and other ecosystem services. (C) 2011 Elsevier B.V. All rights reserved.

AB Artificially constructed wetlands offer a low-cost treatment alternative to remove a number of pollutants found in effluent water from industry, mining, agriculture, and urban areas. The determination of treatment efficiency cannot be determined without understanding the flow dynamics of individual parcels of water through the wetland. A method for tracking parcels of water is proposed, using Rhodamine-WT as a tracer. A series of tracer tests were conducted on a 1.2 ha treatment wetland. Bromide and Rhodamine-WT were simultaneously dosed into the inlet and monitored at 60 sampling locations for 5 weeks. Rhodamine-WT concentrations were found to be coincident with bromide. For all three events the relationship between Rhodamine-WT concentration and bromide concentration was linear at each sampling point with a slope of 0.82. The peak concentration of Rhodamine-WT and bromide was also found to coincide throughout the wetland. Rhodamine-WT can be used to determine the movement of individual parcels of water through a treatment wetland and used to determine treatment efficiencies at individual locations within a wetland.

AB There remains limited research on cardiovascular disease (CVD) risk factors in Puerto Rican adults. We compared lifestyle and CVD risk factors in Puerto Rican men and women with normal fasting glucose (NFG), impaired fasting glucose (IFG), or type 2 diabetes (T2D), and investigated achievement of American Diabetes Association (ADA) treatment goals in those with T2D. Baseline data from the Boston Puerto Rican Health Study were analyzed, which included 1,287 adults aged 45-75 years. Obesity, hyperglycemia, and dyslipidemia were prevalent and increased from NFG to IFG and T2D. In individuals without T2D, fasting insulin correlated significantly with body mass index. Achievement of ADA goals was poor; LDL cholesterol was most achieved (59.4%), followed by blood pressure (27.2%) and glycosylated hemoglobin (27.0%). Poverty, female sex, current alcohol use, and diabetes or anti-hypertensive medication use were associated with not meeting goals. Puerto Rican adults living in the Boston area showed several metabolic abnormalities and high CVD risk, likely due to pervasive obesity and socio-economic disparities.

AB Regulatory approval of ozone has increased commercial interest in the development of applications to ensure produce quality and safety. However, ozone sometimes fails to inactivate microorganisms on packaged produce and this may be a consequence of poor diffusion into packages. Gaseous ozone (900 +/- 12 mu L/L) was applied to several common plastic films with a range of ventilation areas and diffusion through them determined. A semi-quantitative method using the reaction of ozone with indigo trisulfonate or with indigo carmine dye solutions was used. Dye de-colorization occurred relatively rapidly (in less than 1 h) after exposure to ozone, indicating that it diffused through all tested materials. Although the extent of ozone diffusion followed the sequence of high-density polyethylene > polypropylene > low density polyethylene, differences among them were small and not significant (P>0.05). Ozone diffusion was also determined through a low density polyethylene film with ventilation areas of 1.3, 5.2, and 10.4% created by circular holes 6.5 mm in diameter. Gradual but modest increases in ozone diffusion occurred as the ventilation area increased. (C) 2011 Elsevier B.V. All rights reserved.

AB This simulation research was conducted in order to develop a large-fire risk assessment system for the contiguous land area of the United States. The modeling system was applied to each of 134 Fire Planning Units (FPUs) to estimate burn probabilities and fire size distributions. To obtain stable estimates of these quantities, fire ignition and growth was simulated for 10,000 to 50,000 "years" of artificial weather. The fire growth simulations, when run repeatedly with different weather and ignition locations, produce burn probabilities and fire behavior distributions at each landscape location (e.g., number of times a "cell" burns at a given intensity divided by the total years). The artificial weather was generated for each land unit using (1) a fire danger rating index known as the Energy Release Component (ERC) which is a proxy for fuel moisture contents, (2) a time-series analysis of ERC to represent daily and seasonal variability, and (3) distributions of wind speed and direction from weather records. Large fire occurrence was stochastically modeled based on historical relationships to ERC. The simulations also required spatial data on fuel structure and topography which were acquired from the LANDFIRE project ( http://www.landfire.gov ). Fire suppression effects were represented by a statistical model that yields a probability of fire containment based on independent predictors of fire growth rates and fuel type. The simulated burn probabilities were comparable to observed patterns across the U.S. over the range of four orders of magnitude, generally falling within a factor of 3 or 4 of historical estimates. Close agreement between simulated and historical fire size distributions suggest that fire sizes are determined by the joint distributions of spatial opportunities for fire growth (dependent on fuels and ignition location) and the temporal opportunities produced by conducive weather sequences. The research demonstrates a practical approach to using fire simulations at very broad scales for purposes of operational planning and perhaps ecological research.

AB Covalent attachment of enzymes to cellulosic materials like cotton is of interest where either release or loss of enzyme activity over time needs to be avoided. The covalent attachment of an enzyme to a cellulosic substrate requires either activation of a protein side chain or an organic functional group on the cellulosic substrate. Use of a water soluble carbodiimide to create an amide linkage as the covalent attachment between the enzyme and substrate represents an aqueous-based alternative which may be preferred for textile processes. Here we describe an amide bond-mediated lysozyme immobilization applied to cotton where either the carboxylate side chains of the protein or pendant carboxylates in a citrate, cross-linked cotton support are activated as the O-acyl-isourea intermediate, and the reactive amino nucleophiles are derived from amino-silanized cotton and the protein's amino side chains, respectively. A comparison is made of the two activation approaches to covalently link lysozyme to two different cotton fabrics using the water soluble carbodiimide 1-cyclohexyl-3-(2-morpholinoethyl)-carbodiimide-metho-p-toluene sulfonate. A comparison of the resulting enzyme activities of lysozyme on two different cotton supports showed that linking lysozyme to citrate crosslinked cotton gave higher activity than on aminosilanized cotton. The lysozyme-cellulose conjugate formed on the citrate crosslinked nonwoven cotton fabric gave the highest yield and antimicrobial activity.

AB Headcuts are prominent features in the southwestern United States. Within the Walnut Gulch Experimental Watershed (WGEW) survey data was available to quantify the retreat of the three most prominent headcuts in sub-watershed 63.011 from 1935 to 2006. The headcuts serve as major sediment sources and were investigated to identify and understand factors controlling retreat rate in this watershed. The data was incorporated and analyzed in a geographical information system (GIS). The headcuts have retreated persistently since 1935. A power relationship was fitted by regression (R(2)=0.89) correlating the retreat rate with the product of contributing drainage area and areal precipitation for precipitation exceeding a threshold intensity (130 >= 25 mm hr(-1)). This site specific relationship may not apply universally in other regions. Headcut retreat was not induced by external forcing. The autocyclic behavior of headcut retreat was found typical for the southwestern United States. The data did not allow timing or identification of initial causes for headcut retreat. Data suggests that all three headcuts will continue to retreat in the future, even though the retreat rate of one headcut was severely inhibited by exhumation a layer of cemented material, acting as local base level control. Most of the sediment eroded at the active headcut scarp was not transported very far, indicating that headcutting in this area results in local reworking rather than removal of material from the watershed.

AB Environmental modeling frameworks support scientific model development by providing model developers with domain specific software libraries which are used to aid model implementation. This paper presents an investigation on the framework invasiveness of environmental modeling frameworks. Invasiveness, similar to object-oriented coupling, is defined as the quantity of dependencies between model code and a modeling framework. We investigated relationships between invasiveness and the quality of modeling code, and also the utility of using a lightweight framework design approach in an environmental modeling framework. Five metrics to measure framework invasiveness were proposed and applied to measure dependencies between model and framework code of several implementations of Thornthwaite and the Precipitation-Runoff Modeling System (PRMS), two well-known hydrological models. Framework invasiveness measures were compared with existing common software metrics including size (lines of code), cyclomatic complexity, and object-oriented coupling. Models with lower framework invasiveness tended to be smaller, less complex, and have less coupling. In addition, the lightweight framework implementations of the Thornthwaite and PRMS models were less invasive than the traditional framework model implementations. Our results show that model implementations with higher degrees of framework invasiveness also had structural characteristics which previously have been shown to predict poor maintainability, a non-functional code quality attribute of concern. We conclude that using a framework with a lightweight framework design shows promise in helping to improve the quality of model code and that the lightweight framework design approach merits further attention by environmental modeling framework developers.

Then, the amount of corrosion is determined spatially using an empirical corrosion rate model and the inputs of the first step. The result is a corrosion profile along the length of the fastener generated by summing the corrosion depths determined at each time step. We apply the combined model to predict the annual corrosion depth along a metal fastener in wood decks situated in nine different US cities. Corrosion profiles are found to exhibit the same general shape independently of climatic load, with the largest amount of corrosion occurring at 1-5 mm from the wood surface with corrosion depths ranging from 5 pm in Phoenix. Arizona to 45 mu m in Hilo, Hawaii. Corrosion is confined to the first 7-20 mm of the fastener below the wood surface. By varying the climatic loads, we find that although there is a definite relation between total annual rain and total annual corrosion, under the same rain loads corrosion is higher for a climate with more evenly distributed rain events. The proposed combined model is able to capture corrosion behavior under varying loading. A sensitivity analysis gives guidelines for future corrosion modeling work for fasteners in wood.

AB Current FDA regulations require that juice processors achieve a 5 log CFU/ml reduction of a target pathogen prior to distributing products. Whereas thermal pasteurization reduces the sensory characteristics of juice, pulsed electric field (PEF) treatments can be conducted at lower temperatures and may preserve sensory characteristics.
Escherichia coli O157:H7 (ATCC 43895) and a non-pathogenic E. coli (ATCC 35218), respectively, were inoculated into single-strength strawberry juice with or without 750 ppm sodium benzoate (SB), 350 ppm potassium sorbate (PS), and 2.7% citric acid (CA). Juice was treated at outlet temperatures of 45, 50 and 55 degrees C at a field strength of 18.6 kV/cm for 150 mu s with a laboratory-scale PEF unit. Inactivation of surrogate E. coli at 45, 50, and 55 degrees C were 2.86, 3.12, and 3.79 log CFU/ml, respectively, in plain juice (pH 3.4), and 2.75, 3.52, and 5.11 with the addition of benzoic and sorbic acids (pH 3.5). Inactivation of E. coli O157:H7 under the same conditions were 3.09, 4.08, and 4.71 log CFU/ml, respectively, and 2.27, 3.29, and 5.40 with antimicrobials. E. coli O157:H7 in juice with antimicrobials and 2.7% CA (pH 2.7) treated with PEF was reduced by 2.60, 4.32 and 6.95 log CFU/ml at 45, 50 and 55 degrees C while the surrogate E. coli decreased by 3.54, 5.69, and 7.13 log under the same conditions. When juice (pH 2.7) was held for 6 h without PEF treatment, higher numbers of E. coli 35218 (7.17 log CFU/ml) were inactivated than of acid-resistant E. coli O157:H7 (3.89 log). Slightly greater PEF inactivation of E. coli O157:H7 than of the surrogate bacterium indicates that E. coli ATCC 35218 provides a margin of safety when used as a surrogate for O157:H7 in plain strawberry juice or in juice + SB + PS at 45-50 degrees C. or with SB + PS and CA at 55 degrees C.

AB Imposing user fees in Nature-Based Tourism (NBT) contexts has been a controversial issue. Based on the notions of justice and fairness, this study extended previous work examining the relationship between attitudes toward user fees and spending support. In a proposed structural model of price fairness, fee spending support, and willingness to pay (WTP), this paper identified the antecedents of WTP user fees, and empirically examined to what extent the data fit the model. Furthermore, the moderating role of place attachment in the model was investigated by using multiple-group structural equation modeling. Subjects (n = 562) were recreational tourists to a forest area in the southeast U.S. Results revealed that spending support partially played a mediating role in the relationship between perceived price fairness and WTP user fees. A multiple-group invariance test also demonstrated that while the degree of place identity moderated the effect of price fairness on spending support, the degree of place dependence did not influence the relationships among the antecedents of WTP.

AB Seed collections of the wild relatives of cultivated blackberry and raspberry (Rubus species) are maintained at the National Clonal Germplasm Repository, Corvallis, OR. Information on wild species germination requirements is rarely available, and germination may be poor or slow, making it difficult for scientists to use them for breeding improved cultivars. Eight diverse Rubus species in 6 of the 12 Rubus subgenera from seed stored at -20 degrees C for 1-23 years were studied. Seed weight, seed-coat thickness and hardness varied widely. Scarification with sulfuric acid (98% H(2)SO(4)) or sodium hypochlorite (14% NaOCl) was followed by germination treatments of deionized water (DI), smoke gas or a combination of gibberellic acid (2.03 mg/L GA(3)) and potassium nitrate (34 mg/L KNO(3)) during stratification. The commonly used scarification protocols were not effective for many species; but effective scarification exposure was established based on the amount of embryo damage seen with 2,3,5 triphenyl tetrazolium chloride (TZ) viability testing. H(2)SO(4) scarification followed by a treatment with KNO(3) and GA3 during stratification was highly effective for the most species. Two species in subgenus Anoplobatus had a hilar-end hole that allowed rapid germination of unscarified seed. Some species with extremely hard seed coats had little or no germination, and longer scarification times are suggested based on seed size, seed-coat thickness and hardness and viability testing.

AB An ultra-performance liquid chromatography/ion mobility quadrupole time-of-flight mass spectrometry (UPLC/IM-QTOF-MS) method was developed for profiling the indole alkaloids in yohimbe bark. Many indole alkaloids with the yohimbine or ajmalicine core structure, plus methylated, oxidized and reduced species, were characterized. Common fragments and mass differences are described. It was shown that the use of IMS could provide another molecular descriptor, i.e. molecular shape by rotationally averaged collision cross-section; this is of great value for identification of constituents when reference materials are usually not available. Using the combination of high resolution (similar to 40000) accurate mass measurement with time-aligned parallel (TAP) fragmentation, MS(E) (where E represents collision energy), ion mobility mass spectrometry (IMS) and UPLC chromatography, a total 55 indole alkaloids were characterized and a few new indole alkaloids are reported for the first time.

AB H9N2 influenza A viruses have become endemic in different types terrestrial poultry and wild birds in Asia, and are occasionally transmitted to humans and pigs. To evaluate he role of black-billed magpies (Pica pica) in the evolution of influenza A virus, we conducted two epidemic surveys on avian influenza viruses in wild black-billed magpies in Guangxi, China in 2005 and characterized three isolated black-billed magpie H9N2 viruses (BbM viruses). Phylogenetic analysis indicated that three BbM viruses were almost identical with 99.7 to 100% nucleotide homology in their whole genomes, and were reassortants containing BJ94-like (Ck/BJ/1/94) HA, NA, M, and NS genes, SH/F/98-like (Ck/SH/F/98) PB2, PA, and NP genes, and H5N1-like (Ck/YN/1252/03, clade 1) PB1 genes. Genetic analysis showed that BbM viruses were most likely the result of multiple reassortments between co-circulating H9N2-like and H5N1-like viruses, and were genetically different from other H9N2 viruses because of the existence of H5N1-like PB1 genes. Genotypical analysis revealed that BbM viruses evolved from diverse sources and belonged to a novel genotype (B46) discovered in our recent study. Molecular analysis suggested that BbM viruses were likely low pathogenic reassortants. However, results of our pathogenicity study demonstrated that BbM viruses replicated efficiently in chickens and a mammalian mouse model but were not lethal for infected chickens and mice. Antigenic analysis showed that BbM viruses were antigenic heterologous with the H9N2 vaccine strain. Our study is probably the first report to document and characterize H9N2 influenza viruses isolated from black-billed magpies in southern China. Our results suggest that black-billed magpies were susceptible to H9N2 influenza viruses, which raise concerns over possible transmissions of reassortant H9N2 viruses among poultry and wild birds.

AB Soil water dynamics and drainage are key abiotic factors controlling losses of atmospherically deposited N in Southern California. In this paper soil N leaching and trace gaseous emissions simulated by the DAYCENT biogeochemical model using its original semi-dynamic water flow module were compared to that coupled with a finite element transient water flow module (HYDRUS), for two mixed conifer forests with annual deposition rates of about 70 and 9 kg N ha(-1), in the San Bernardino National Forest. Numerical solution of the Richards equation implemented in HYDRUS water module could improve response of surface soil water dynamics to precipitation pattern, compared to the original, and consequently it resulted in annual N gaseous emission loss about 1.5 similar to 2 times higher. While the two flow modules predicted similar amounts of annual water drainage, the HYDRUS water module simulated more frequent, but smaller drainage fluxes, which favors soil mineralization and downward transport. In normal precipitation years, annual leaching losses predicted by the HYDRUS coupled DAYCENT model was about 5-18 kg N ha(-1) higher due to different temporal patterns of daily water drainage. In dry and wet years, leaching losses were similar. Our analysis suggests that it is necessary to fully capture dynamics of transient water flow (e. g., by numerically solving the transient Richards equation) in order to adequately estimate soil N gaseous emissions and N transport and thus leaching, although it requires more computational resources while the uncertainty in model improvement is still large due to lack of measurements.

AB Seasonal variations in background aerosol optical depth (AOD) and aerosol type are investigated over various ecosystems in China based upon three years' worth of meteorological data and data collected by the Chinese Sun Hazemeter Network. In most parts of China, AODs are at a maximum in spring or summer and at a minimum in autumn or winter. Minimum values (0.10 similar to 0.20) of annual mean AOD at 500 nm are found in the Qinghai-Tibetan Plateau, the remote northeast corner of China, the northern forest ecosystems and Hainan Island. Annual mean AOD ranges from 0.25 to 0.30 over desert and oasis areas, as well as the desertification grasslands in northern China; the annual mean AOD over the Loess Plateau is moderately high at 0.36. Regions where the highest density of agricultural and industrial activities are located and where anthropogenic sulphate aerosol and soil aerosol emissions are consistently high throughout the whole year (e.g., the central-eastern, southern and eastern coastal regions of China) experience annual mean AODs ranging from 0.50 similar to 0.80. Remarkable seasonal changes in the main types of aerosol over northern China (characterized by the Angstrom exponent, a) are seen. Due to biomass and fossil fuel burning from extensive agricultural practices in northern rural areas, concentrations of smoke and soot aerosols rise dramatically during autumn and winter (high a), while the main types of aerosol during spring and summer are dust and soil aerosols (low a). Over southeastern Asia, biomass burning during the spring leads to increases in smoke and soot emissions. Over the Tibetan Plateau and Hainan Island where the atmosphere is pristine, the main types of aerosol are dust and sea salt, respectively.

AB We investigated antitumor effects of the following four extracts of freeze-dried Hericium erinaceus mushrooms in Balb/c mice intracutaneously transplanted on the backs with CT-26 colon cancer cells: HWE, hot water extraction by boiling in water for 3 h; MWE, microwaving in 50% ethanol/water at 60W for 3 min; and ACE and AKE, boiling in 1% HCl or 3% NaOH for 2 h. HWE and MWE with a higher content of beta-glucans, determined by an assay kit, than ACE and MKE were active in all bioassays. Gas chromatography/mass spectrometry analyses showed the presence of 40, 27, 16, and 13 compounds, respectively, in the four extracts. Daily intraperitoneal (ip) injections of HWE and MWE for 2 weeks significantly reduced tumor weights by 38 and 41%. Tumor regressions were associated with changes in the following cancer biomarkers as compared to phosphate buffer (PBS)-treated control mice: 2.7- and 2.4-fold increases in cytolytic activity of splenic natural killer (NK) cells; restored nitric oxide production and phagocytosis in peritoneal macrophages to 95-98% of normal levels; similar to 2-fold increase in released pro-inflammatory cytokines tumor necrosis factor-alpha, interleulcin-1 beta, and interleukin-6 from macrophages; and similar to 56 and similar to 60% reductions in the number of blood vessels inside the tumor. The pro-angiogenic factors vascular endothelial growth factor (VEGF), cyclooxygenase 2 (COX-2), and 5-lipoxygenase (5-LOX) were also significantly reduced in mRNA and protein expression by tumor genes. Enzyme-linked immunosorbent assay of tumor cells confirmed reduced expression of COX-2 and 5-LOX (32 and 31%). Reduced COX-2 and 5-LOX expression down-regulated VEGF expression, resulting in inhibition of neo-angiogenesis inside the tumors. The results indicate that induction of NK activity, activation of macrophages, and inhibition of angiogenesis all contribute to the mechanism of reduction of tumor size.

AB Ceftiofur is a third-generation cephalosporin antibiotic that has been widely used to treat bacterial infections in concentrated animal feeding operations (CAFOs). Land application of CAFO waste may lead to the loading of ceftiofur residues and its metabolites to the environment. To understand the potential contamination of the antibiotic in the environment, the degradation kinetics and mechanisms of ceftiofur in solutions blended with and without the recycled water derived from a beef farm were investigated The transformation of ceftiofur in aqueous solutions in the presence of the CAFO recycled water was the combined process of hydrolysis and biodegradation. The total degradation rates of ceftiofur at 15 degrees C, 25 degrees C, 35 degrees C, and 45 degrees C varied from 0.4-2.8 x 10(-3), 1.4-4.4 x 10(-3), 6.3-11 x 10(-3), and 11-17 x 10(-3) h(-1), respectively, in aqueous solutions blended with 1 to 596 CAFO recycled water. Hydrolysis of ceftiofur increased with incubation temperature from 15 to 45 C. The biodegradation rates of ceftiofur were also temperature-dependent and increased with the application amounts of the recycled CAFO water. Cef-aldehyde and desfuroylceftiofur (DFC) were identified as the main biodegradation and hydrolysis products, respectively. This result suggests that the primary biodegradation mechanism of ceftiofur was the cleavage of the beta-lactam ring, while hydrolytic cleavage occurred at the thioester bond Unlike DFC and ceftiofur, cef-aldehyde does not contain a beta-lactam ring and has less antimicrobial activity, indicating that the biodegradation of ceftiofur in animal wastewater may mitigate the potentially adverse impact of the antibiotic to the environment.

AB Blueberries (BB) have recently been shown to have cardioprotective effects and to prevent atherosclerosis in rodent models. However, the bioactive compounds in BB responsible for these effects have not yet been characterized. Seven phenolic acids (7PA) were identified as metabolites in the serum of rats fed diets supplemented with 10% freeze-dried BB. In this study, 7PA were evaluated for their potential atheroprotective effects in murine macrophage cell line RAW 264.7. 7PA were found to inhibit LPS-induced mRNA expression and protein levels of pro-inflammatory cytokine TNF-alpha and IL-6 by reducing MAPK JNK, p38, and Erk1/2 phosphorylation. After treatment with 7PA for 2 weeks, mRNA expression and protein levels of scavenger receptor CD36 were decreased (P < 0.05), whereas type A scavenger receptor (SR-A) remained unchanged. Moreover, foam cell formation induced by oxLDL and oxLDL binding to macrophages was also inhibited by 7PA In addition, 7PA increased (P < 0.05) expression and protein levels of ATP-binding cassette transporter Al (ABCA1), which facilitates cholesterol efflux and reduces cholesterol accumulation in macrophages. In summary, the present study demonstrates that certain phenolic acids are potential in vivo atheroprotective compounds following BB consumption in the rodent model. Because BB contain many phytochemicals, other as yet unidentified bioactive compounds may also be important in preventing atherosclerosis in this model and, possibly, in humans.

AB The stable fly, Stomoxys calcitrans (L.), has been considered one of the most serious biting flies of confined and pastured livestock. The economic losses caused by the stable fly to the cattle industry in the United States exceed $2 billion annually. Current practices for managing stable flies using insecticides provide only marginal control. Insecticide resistance has also been : recently reported in stable flies. The present study reports the use of plant based insecticides, for example, essential oils, as alternatives for managing this fly pest The toxicity of several plant essential oils and selected ingredient compounds was evaluated by contact and fumigant toxicity bioassays. Catnip oil (20 mg dosage) showed the highest toxicity against stable flies, the shortest knock down time (similar to 7 min), and the quickest lethal time (similar to 19 min). Toxicity levels similar catnip, oil were found among three insect repellent compounds (N,N-diethyl-3-methylbenzamide, 2-methylpiperidinyl-3-Cyclohexene-1-carboxamide, (1S,2'S)-2-methylpiperidinyl-3-cyclohexene-1-carboxamide). No differences in knock down and lethal times were found among the catnip oil and its two active ingredient compounds. Similar stable fly mortality was observed using a 20 mg dose of catnip oil in a modified K&D system and a fumigant jar. When catnip oil was topically applied to stable flies, the least lethal dose was 12.5 mu g/fly, and a 50 mu g/fly dose resulted in 100% mortality. The blood feeding behavior of stable flies was also negatively affected by the topical application of catnip oil, and the effect was dose dependent This study demonstrated that catnip oil has both contact and fumigant toxicity against the stable fly and thus has the potential as an alternative for stable fly control.

AB We developed and evaluated a new method of low-pressure gas chromatography-tandem mass spectrometry (LP-GC/MS-MS) using a triple quadrupole instrument for fast analysis of 150 relevant pesticides in four representative fruits and vegetables. This LP-GC (vacuum outlet) approach entails coupling a 10 m, 0.53 mm id., 1 mu m film analytical column between the MS transfer line and a 3m, 0.15 mm id. capillary at the inlet. The MS creates a vacuum in the 10 m analytical column, which reduces the viscosity of the He carrier gas and thereby shifts the optimal flow rate to greater velocity. By taking advantage of the H-2-like properties of He under vacuum, the short analytical column, a rapid oven temperature ramp rate, and the high selectivity and sensitivity of MS/MS, 150 pesticides were separated in <6.5 min. The 2.5 ms dwell time and 1 ms interscan delay of the MS/MS instrument were critical for achieving >8 data points across the 2-3 s wide peaks. To keep dwell and cycle times constant across all peaks, each segment consisted of 30 analytes (60 transitions). For assessment, we injected extracts of spiked broccoli, cantaloupe, lemon, and sweet potato from the updated QuEChERS sample preparation method. Average recoveries (n = 72) were 70-120% for 144 of the pesticides, and reproducibilities were <20% RSD for all but 4 analytes. Also, detection limits were <5 ng/g for all but a few pesticides, depending on the matrix. In addition to high quality performance, the method gave excellent reliability and high sample throughput, including easy peak integration to obtain rapid results. Published by Elsevier B.V.

AB Streptococcus iniae is one of the most economically important Gram-positive pathogens in cultured fish species worldwide. The USDA-ARS Aquatic Animal Health Research Unit developed a modified (contains concentrated culture supernatant) S. iniae bacterin that has been demonstrated to be efficacious, and protection is mediated by specific anti-S. iniae antibodies. Although effective, the specific vaccine components important for efficacy are not known. In the present study, an immunoproteomic approach was utilized to identify whole-cell lysate proteins of S. iniae that stimulated specific antibody production in Nile tilapia (Oreochromis niloticus) following vaccination. Groups of tilapia were vaccinated by intraperitoneal injection with the modified S. iniae bacterin or were mock-vaccinated, and at 30 d post-vaccination sera samples were obtained from individual fish. Vaccination of tilapia with the S. iniae vaccine stimulated significantly elevated specific antibody responses against proteins of the bacterium and passive immunization of tilapia with this serum demonstrated the antibodies were highly protective. Whole-cell lysate proteins of S. iniae were separated by 2D-PAGE and were probed with a pooled serum sample from vaccinated tilapia. A total of eleven unique immunogenic proteins were positively identified by mass spectrometry. Based on research conducted on homologous proteins in other Streptococcus spp., antibodies specific for three of the identified proteins, enolase, glyceraldehyde-3-phosphate dehydrogenase, and fructose-bisphosphate aldolase, are likely involved in protection from streptococcosis caused by S. iniae.

AB YbjN, encoding an enterobacteria-specific protein, is a multicopy suppressor of temperature sensitivity in the ts9 mutant strain of Escherichia coli. In this study, we further explored the role(s) of ybjN. First, we demonstrated that the ybjN transcript was about 10-fold lower in the ts9 strain compared to that of E. coli strain BW25113 (BW). Introduction of multiple copies of ybjN in the ts9 strain resulted in over-expression of ybjN by about 10-fold as compared to that of BW. These results suggested that temperature sensitivity of the ts9 mutant of E. coli may be related to expression levels of ybjN. Characterization of E. coli ybjN mutant revealed that ybjN mutation resulted in pleiotropic phenotypes, including increased motility, fimbriation (auto-aggregation), exopolysaccharide production, and biofilm formation. In contrast, over-expression of ybjN (in terms of multiple copies) resulted in reduced motility, fimbriation, exopolysaccharide production, biofilm formation and acid resistance. In addition, our results indicate that a ybjN-homolog gene from Erwinia amylovora, a plant enterobacterial pathogen, is functionally conserved with that of E. coli, suggesting similar evolution of the YbjN family proteins in enterobacteria. A microarray study revealed that the expression level of ybjN was inversely correlated with the expression of flagellar, fimbrial and acid resistance genes. Over-expression of ybjN significantly down-regulated genes involved in citric acid cycle, glycolysis, the glyoxylate shunt, oxidative phosphorylation, amino acid and nucleotide metabolism. Furthermore, over-expression of ybjN up-regulated toxin-antitoxin modules, the SOS response pathway, cold shock and starvation induced transporter genes. Collectively, these results suggest that YbjN may play important roles in regulating bacterial multicellular behavior, metabolism, and survival under stress conditions in E. coli. These results also suggest that ybjN over-expression-related temperature rescue of the ts9 mutant may be due to down-regulation of metabolic activity and activation of stress response genes in the ts9 mutant.

AB Two phytonutrient mixtures, VAC (carvacrol, cinnamaldehyde, and Capsicum oleoresin), and MC (Capsicum oleoresin and turmeric oleoresin), were evaluated for their effects on chicken immune responses following immunization with an Eimeria profilin protein. Chickens were fed with a non-supplemented diet, or with VAC- or MC-supplemented diets, immunized with profilin, and orally challenged with virulent oocysts of Eimeria tenella. Immunity against infection was evaluated by body weight, fecal oocyst shedding, profilin antibody levels, lymphocyte recall responses, cytokine expression, and lymphocyte subpopulations. Following immunization and infection, chickens fed the VAC- or MC-supplemented diets showed increased body weights, greater profilin antibody levels, and/or greater lymphocyte proliferation compared with non-supplemented controls. Prior to Eimeria infection, immunized chickens on the MC-supplemented diet showed reduced IFN-gamma and IL-6 levels, but increased expression of TNFSF15, compared with non-supplemented controls. Post-infection levels of IFN-gamma and IL-6 were increased, while IL-17F transcripts were decreased, with MC-supplementation. For VAC-supplemented diets, decreased IL-17F and TNFSF15 levels were observed only in infected chickens. Finally, immunized chickens fed the MC-supplemented diet exhibited increased MHC class II(+), CD4(+), CD8(+), TCR1(+), or TCR2(+). T cells compared with nonsupplemented controls. Animals on the VAC-containing diet only displayed an increase in K1(+) macrophages. In conclusion, dietary supplementation with VAC or MC alters immune parameters following recombinant protein vaccination against avian coccidiosis. Published by Elsevier B.V.

AB The objective of three experiments was to determine the impact of supplementing sericea lespedeza (Lespedeza cuneata; SL) in three concentrations in a loose or pelleted diet on gastrointestinal nematodes (GIN) in small ruminants. Experiments on lambs were conducted at the USDA, Agricultural Research Service in Booneville, AR (Exp. 1) and at Louisiana State University in Baton Rouge, LA (Exp. 2); an experiment on goat kids occurred at University of Maryland-Eastern Shore (Exp. 3). Exp. 1 used crossbred hair sheep lambs naturally infected with GIN that were randomly allocated to diets containing 0, 25, 50, and 75% SL diets (n = 11 or 12/diet). Exp. 2 consisted of Haemonchus contortus-inoculated crossbred wool breed lambs that were blocked by gender and FEC and randomly assigned to 0, 25, 50, or 75% SL diet (n = 8/diet). Fecal egg counts (FEC) and blood packed cell volume (PCV) were not influenced by SL supplementation in Exp. 1 and 2. Exp. 3 consisted of naturally GIN infected Boer crossbred goat kids in individual pens. Kids were blocked by FEC and randomly allotted to treatments of 0, 20, 40, or 60% SL with 9-13 goats/diet. The more SL fed, the greater the reduction in FEC (P < 0.001). There was an increase in PCV in SL fed goats (P < 0.001). Larval speciation at the end of the experiment indicated that feces from control animals produced 43% H. contortus larva while 20, 40 and 60% SL resulted in 39%, 35% and 31% H. contortus larvae, respectively. Feeding dried SL may be less effective in lambs than kids, though concurrent studies must be conducted to confirm this. Published by Elsevier B.V.

AB The gray wolf (Canis lupus) was found to be a new natural definitive host for Neospora caninum. Neospora-like oocysts were found microscopically in the feces of three of 73 wolves from Minnesota examined at necropsy. N. caninum-specific DNA was amplified from the oocysts of all three wolves. Oocysts from one wolf were infective for the gamma interferon gene knock out (KO) mice. Viable N. caninum (designated NcWolfUS1) was isolated in cell cultures seeded with tissue homogenate from the infected mouse. Typical thick walled tissue cysts were found in outbred mice inoculated with the parasite from the KO mouse. Tissue stages in mice stained positively with N. caninum-specific polyclonal antibodies. Our observation suggests that wolves may be an important link in the sylvatic cycle of N. caninum. (C) 2011 Elsevier B.V. All rights reserved.

AB Catmint oil and hydrogenated catmint oil were evaluated as repellents for adult Tribolium casteneum (Herbst) (Coleoptera: Tenebrionidae), the red flour beetle, and T. confusum (DuVal), the confused flour beetle, using both a traditional method of visual assessment of distribution and a video recording method to determine movement patterns of individual insects. Visual assessments of distribution using groups of adults showed that the hydrogenated catmint oil was more effective than the pure catmint oil, but there was no significant difference between species. However, when repellency was measured using single insects and the visual recording system, both oils were significantly more repellent to T. castaneum than T. confusum at the concentrations evaluated in the study. Avoidance movement and change in direction when T. castaneum encountered the repellent were observed. Results indicate that repellents may be more accurately assessed using single insects rather than groups of individuals, and simple visual observations of distribution may be less sensitive in measuring repellent efficacy. Procedures for utilizing a video system are described as models for future evaluations of repellents for stored-product beetles.

AB Optimal flowering time is critical to the success of modern agriculture. Sorghum is a short-day tropical species that exhibits substantial photoperiod sensitivity and delayed flowering in long days. Genotypes with reduced photoperiod sensitivity enabled sorghum's utilization as a grain crop in temperate zones worldwide. In the present study, Ma(1), the major repressor of sorghum flowering in long days, was identified as the pseudoresponse regulator protein 37 (PRR37) through positional cloning and analysis of SbPRR37 alleles that modulate flowering time in grain and energy sorghum. Several allelic variants of SbPRR37 were identified in early flowering grain sorghum germplasm that contain unique loss-of-function mutations. We show that in long days SbPRR37 activates expression of the floral inhibitor CONSTANS and represses expression of the floral activators Early Heading Date 1, FLOWERING LOCUS T, Zea mays CENTRORADIALIS 8, and floral induction. Expression of SbPRR37 is light dependent and regulated by the circadian clock, with peaks of RNA abundance in the morning and evening in long days. In short days, the evening-phase expression of SbPRR37 does not occur due to darkness, allowing sorghum to flower in this photoperiod. This study provides insight into an external coincidence mechanism of photoperiodic regulation of flowering time mediated by PRR37 in the short-day grass sorghum and identifies important alleles of SbPRR37 that are critical for the utilization of this tropical grass in temperate zone grain and bioenergy production.

AB Balcha indica Mani and Kaul (Hymenoptera: Eupelmidae) is a solitary ectoparasitoid attacking larvae, prepupae, and pupae of the emerald ash borer, Agrilus planipennis Fairmaire (Hymenoptera: Eupelmidae). Its fecundity, oviposition rate, longevity, and development time were determined in the laboratory under standard rearing conditions (25 +/- 2 degrees C, 65 +/- 10% relative humidity, and 14:10 L:D). Adults lived a mean of 59 days with a maximum of 117 days. Lifetime adult fecundity averaged 36 eggs with a maximum 94 eggs per female. The egg stage lasted for a maximum of four days with similar to 50% eggs hatched within two days. The development time of the first instars lasted for a maximum of nine days; 50% of the first instars completed their development (i.e., molted to the next instar) within five days. Instars of the intermediate and final stage larvae (after molting of the first instars occurred) could not be distinguished until they reached the pupal stage, and 50% of those larvae pupated similar to 62 days after adult oviposition. Under the standard rearing conditions, 50% of B. indica took similar to 83 days to complete the life cycle (from egg to adult emergence) ranging from 47 to 129 days. These results suggest that B. indica may not have more than two generations in the mid-Atlantic and Midwest regions of United States, where normal growing seasons-with average temperature above 25 degrees C-are normally less than six months (May-October). Because of the long life span and oviposition period of adults, however, B. indica is likely to have overlapping generations.

DT Article
ID HERBACEOUS VEGETATION; DIVERSITY; BIODIVERSITY; COMMUNITY; HYPOTHESIS
AB For more than 30 years, the relationship between net primary productivity and species richness has generated intense debate in ecology about the processes regulating local diversity. The original view, which is still widely accepted, holds that the relationship is hump-shaped, with richness first rising and then declining with increasing productivity. Although recent meta-analyses questioned the generality of hump-shaped patterns, these syntheses have been criticized for failing to account for methodological differences among studies. We addressed such concerns by conducting standardized sampling in 48 herbaceous-dominated plant communities on five continents. We found no clear relationship between productivity and fine-scale (meters(-2)) richness within sites, within regions, or across the globe. Ecologists should focus on fresh, mechanistic approaches to understanding the multivariate links between productivity and richness.

TI Chicken interferon alpha pretreatment reduces virus replication of

AB Background: Type I interferons, including interferon alpha (IFN-alpha), represent one of the first lines of innate immune defense against influenza virus infection. Following natural infection of chickens with avian influenza virus (AIV), transcription of IFN-alpha is quickly up regulated along with multiple other immune-related genes. Chicken IFN-alpha up regulates a number of important anti-viral response genes and has been demonstrated to be an important cytokine to establish anti-viral immunity. However, the mechanisms by which interferon inhibit virus replication in avian species remains unknown as does the biological activity of chicken interferon in other avian species.
Methods: In these studies, we assessed the protective potential of exogenous chicken IFN-alpha applied to chicken, duck, and turkey primary lung cell cultures prior to infection with the pandemic H1N1 virus (A/turkey/Virginia/SEP4/2009) and an established avian H5N9 virus (A/turkey/Wisconsin/1968). Growth kinetics and induction of select immune response genes, including IFN-alpha and myxovirus-resistance gene I (Mx), as well as proinflammatory cytokines (IL-1 beta and IL-6), were measured in response to chicken IFN-alpha and viral infection over time.
Results: Results demonstrate that pretreatment with chicken IFN-alpha before AIV infection significantly reduced virus replication in both chicken-and turkey-origin lung cells and to a lesser degree the duck-origin cells. Virus growth was reduced by approximately 200-fold in chicken and turkey cells and 30-fold in duck cells after 48 hours of incubation. Interferon treatment also significantly decreased the interferon and proinflammatory response during viral infection. In general, infection with the H1N1 virus resulted in an attenuated interferon and proinflammatory response in these cell lines, compared to the H5N9 virus.
Conclusions: Taken together, these studies show that chicken IFN-alpha reduces virus replication, lower host innate immune response following infection, and is biologically active in other avian species.

AB The diverse vegetation types and carbon pools of the U. S. Pacific Northwest (PNW) are tightly coupled to fire regimes that depend on climate and fire suppression. To realistically assess the effects of twenty-first-century climate change on PNW fire and carbon dynamics, we developed a new fire suppression rule for the MC1 dynamic general vegetation model that we ran under three climate change scenarios. Climate projections from the CSIRO Mk3, MIROC 3.2 medres, and Hadley CM3 general circulation models, forced by the A2 CO(2) emissions scenario, were downscaled to a 30 arc-second (similar to 0.6 km(2)) grid. Future climates amplify the already strong seasonality of temperature and precipitation across the domain. Simulations displayed large increases in area burned (76%-310%) and burn severities (29%-41%) by the end of the twenty-first century. The relatively dry ecosystems east of the Cascades gain carbon in the future despite projections of more intense wildfires, while the mesic maritime forests lose up to 1.2 Pg C from increased burning. Simulated fire suppression causes overall carbon gains yet leaves ecosystems vulnerable to large future fires. Overall, our simulations suggest the Pacific Northwest has the potential to sequester similar to 1 Pg C over the next century unless summer droughts severely intensify fire regimes.

AB Background: Cultivated watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus] is an important agriculture crop world-wide. The fruit of watermelon undergoes distinct stages of development with dramatic changes in its size, color, sweetness, texture and aroma. In order to better understand the genetic and molecular basis of these changes and significantly expand the watermelon transcript catalog, we have selected four critical stages of watermelon fruit development and used Roche/454 next-generation sequencing technology to generate a large expressed sequence tag (EST) dataset and a comprehensive transcriptome profile for watermelon fruit flesh tissues.
Results: We performed half Roche/454 GS-FLX run for each of the four watermelon fruit developmental stages (immature white, white-pink flesh, red flesh and over-ripe) and obtained 577,023 high quality ESTs with an average length of 302.8 bp. De novo assembly of these ESTs together with 11,786 watermelon ESTs collected from GenBank produced 75,068 unigenes with a total length of approximately 31.8 Mb. Overall 54.9% of the unigenes showed significant similarities to known sequences in GenBank non-redundant (nr) protein database and around two-thirds of them matched proteins of cucumber, the most closely-related species with a sequenced genome. The unigenes were further assigned with gene ontology (GO) terms and mapped to biochemical pathways. More than 5,000 SSRs were identified from the EST collection. Furthermore we carried out digital gene expression analysis of these ESTs and identified 3,023 genes that were differentially expressed during watermelon fruit development and ripening, which provided novel insights into watermelon fruit biology and a comprehensive resource of candidate genes for future functional analysis. We then generated profiles of several interesting metabolites that are important to fruit quality including pigmentation and sweetness. Integrative analysis of metabolite and digital gene expression profiles helped elucidating molecular mechanisms governing these important quality-related traits during watermelon fruit development.
Conclusion: We have generated a large collection of watermelon ESTs, which represents a significant expansion of the current transcript catalog of watermelon and a valuable resource for future studies on the genomics of watermelon and other closely-related species. Digital expression analysis of this EST collection allowed us to identify a large set of genes that were differentially expressed during watermelon fruit development and ripening, which provide a rich source of candidates for future functional analysis and represent a valuable increase in our knowledge base of watermelon fruit biology.

WIDE ANALYSIS; SEQUENCE; SALMONELLA
AB Background: Comparative Genomic Hybridization (CGH) with DNA microarrays has many biological applications including surveys of copy number changes in tumorogenesis, species detection and identification, and functional genomics studies among related organisms. Array CGH has also been used to infer phylogenetic relatedness among species or strains. Although the use of the entire genome can be seen as a considerable advantage for use in phylogenetic analysis, few such studies have questioned the reliability of array CGH to correctly determine evolutionary relationships. A potential flaw in this application lies in the fact that all comparisons are made to a single reference species. This situation differs from traditional DNA sequence, distance-based phylogenetic analyses where all possible pairwise comparisons are made for the isolates in question. By simulating array data based on the Neurospora crassa genome, we address this potential flaw and other questions regarding array CGH phylogeny.
Results: Our simulation data indicates that having a single reference can, in some cases, be a serious limitation when using this technique. Additionally, the tree building process with a single reference is sensitive to many factors including tree topology, choice of tree reconstruction method, and the distance metric used.
Conclusions: Without prior knowledge of the topology and placement of the reference taxon in the topology, the outcome is likely to be wrong and the error undetected. Given these limitations, using CGH to reveal phylogeny based on sequence divergence does not offer a robust alternative to traditional phylogenetic analysis.

SO PLOS ONE

DT Article
ID SCHIZOPHRENIA; INFECTION; CELLS; RATS; MICE; BEHAVIOR; NEURONS; STORAGE;
IMPACT; RISK
AB The highly prevalent parasite Toxoplasma gondii manipulates its host's behavior. In infected rodents, the behavioral changes increase the likelihood that the parasite will be transmitted back to its definitive cat host, an essential step in completion of the parasite's life cycle. The mechanism(s) responsible for behavioral changes in the host is unknown but two lines of published evidence suggest that the parasite alters neurotransmitter signal transduction: the disruption of the parasite-induced behavioral changes with medications used to treat psychiatric disease (specifically dopamine antagonists) and identification of a tyrosine hydroxylase encoded in the parasite genome. In this study, infection of mammalian dopaminergic cells with T. gondii enhanced the levels of K+-induced release of dopamine several-fold, with a direct correlation between the number of infected cells and the quantity of dopamine released. Immunostaining brain sections of infected mice with dopamine antibody showed intense staining of encysted parasites. Based on these analyses, T. gondii orchestrates a significant increase in dopamine metabolism in neural cells. Tyrosine hydroxylase, the rate-limiting enzyme for dopamine synthesis, was also found in intracellular tissue cysts in brain tissue with antibodies specific for the parasite-encoded tyrosine hydroxylase. These observations provide a mechanism for parasite-induced behavioral changes. The observed effects on dopamine metabolism could also be relevant in interpreting reports of psychobehavioral changes in toxoplasmosis-infected humans.

TI Combining tower mixing ratio and community model data to estimate

AB We evaluated an idealized boundary layer (BL) model with simple parameterizations using vertical transport information from community model outputs (NCAR/NCEP Reanalysis and ECMWF Interim Analysis) to estimate regional-scale net CO2 fluxes from 2002 to 2007 at three forest and one grassland flux sites in the United States. The BL modeling approach builds on a mixed-layer model to infer monthly average net CO2 fluxes using high-precision mixing ratio measurements taken on flux towers. We compared BL model net ecosystem exchange (NEE) with estimates from two independent approaches. First, we compared modeled NEE with tower eddy covariance measurements. The second approach (EC-MOD) was a data-driven method that upscaled EC fluxes from towers to regions using MODIS data streams. Comparisons between modeled CO2 and tower NEE fluxes showed that modeled regional CO2 fluxes displayed interannual and intra-annual variations similar to the tower NEE fluxes at the Rannells Prairie and Wind River Forest sites, but model predictions were frequently different from NEE observations at the Harvard Forest and Howland Forest sites. At the Howland Forest site, modeled CO2 fluxes showed a lag in the onset of growing season uptake by 2 months behind that of tower measurements. At the Harvard Forest site, modeled CO2 fluxes agreed with the timing of growing season uptake but underestimated the magnitude of observed NEE seasonal fluctuation. This modeling inconsistency among sites can be partially attributed to the likely misrepresentation of atmospheric transport and/or CO2 gradients between ABL and the free troposphere in the idealized BL model. EC-MOD fluxes showed that spatial heterogeneity in land use and cover very likely explained the majority of the data-model inconsistency. We show a site-dependent atmospheric rectifier effect that appears to have had the largest impact on ABL CO2 inversion in the North American Great Plains. We conclude that a systematic BL modeling approach provided new insights when employed in multiyear, cross-site synthesis studies. These results can be used to develop diagnostic upscaling tools, improving our understanding of the seasonal and interannual variability of surface CO2 fluxes.

AB Phenotypic plasticity allows organisms to produce alternative phenotypes under different conditions and represents one of the most important ways by which organisms adaptively respond to the environment. However, the relationship between phenotypic plasticity and molecular evolution remains poorly understood. We addressed this issue by investigating the evolution of genes associated with phenotypically plastic castes, sexes, and developmental stages of the fire ant Solenopsis invicta. We first determined if genes associated with phenotypic plasticity in S. invicta evolved at a rapid rate, as predicted under theoretical models. We found that genes differentially expressed between S. invicta castes, sexes, and developmental stages all exhibited elevated rates of evolution compared with ubiquitously expressed genes. We next investigated the evolutionary history of genes associated with the production of castes. Surprisingly, we found that orthologs of caste-biased genes in S. invicta and the social bee Apis mellifera evolved rapidly in lineages without castes. Thus, in contrast to some theoretical predictions, our results suggest that rapid rates of molecular evolution may not arise primarily as a consequence of phenotypic plasticity. Instead, genes evolving under relaxed purifying selection may more readily adopt new forms of biased expression during the evolution of alternate phenotypes. These results suggest that relaxed selective constraint on protein-coding genes is an important and underappreciated element in the evolutionary origin of phenotypic plasticity.

AB Background: As scientists continue to pursue various 'omics-based research, there is a need for high quality data for the most fundamental 'omics of all: genomics. The bacterium Paenibacillus larvae is the causative agent of the honey bee disease American foulbrood. If untreated, it can lead to the demise of an entire hive; the highly social nature of bees also leads to easy disease spread, between both individuals and colonies. Biologists have studied this organism since the early 1900s, and a century later, the molecular mechanism of infection remains elusive. Transcriptomics and proteomics, because of their ability to analyze multiple genes and proteins in a high-throughput manner, may be very helpful to its study. However, the power of these methodologies is severely limited without a complete genome; we undertake to address that deficiency here.
Results: We used the Illumina GAIIx platform and conventional Sanger sequencing to generate a 182-fold sequence coverage of the P. larvae genome, and assembled the data using ABySS into a total of 388 contigs spanning 4.5 Mbp. Comparative genomics analysis against fully-sequenced soil bacteria P. JDR2 and P. vortex showed that regions of poor conservation may contain putative virulence factors. We used GLIMMER to predict 3568 gene models, and named them based on homology revealed by BLAST searches; proteases, hemolytic factors, toxins, and antibiotic resistance enzymes were identified in this way. Finally, mass spectrometry was used to provide experimental evidence that at least 35% of the genes are expressed at the protein level.
Conclusions: This update on the genome of P. larvae and annotation represents an immense advancement from what we had previously known about this species. We provide here a reliable resource that can be used to elucidate the mechanism of infection, and by extension, more effective methods to control and cure this widespread honey bee disease.

AB Emerging plant pathogens have largely been a consequence of the movement of pathogens to new geographic regions. Another documented mechanism for the emergence of plant pathogens is hybridization between individuals of different species or subspecies, which may allow rapid evolution and adaptation to new hosts or environments. Hybrid plant pathogens have traditionally been difficult to detect or confirm, but the increasing ease of cloning and sequencing PCR products now makes the identification of species that consistently have genes or alleles with phylogenetically divergent origins relatively straightforward. We investigated the genetic origin of Phytophthora andina, an increasingly common pathogen of Andean crops Solanum betaceum, S. muricatum, S. quitoense, and several wild Solanum spp. It has been hypothesized that P. andina is a hybrid between the potato late blight pathogen P. infestans and another Phytophthora species. We tested this hypothesis by cloning four nuclear loci to obtain haplotypes and using these loci to infer the phylogenetic relationships of P. andina to P. infestans and other related species. Sequencing of cloned PCR products in every case revealed two distinct haplotypes for each locus in P. andina, such that each isolate had one allele derived from a P. infestans parent and a second divergent allele derived from an unknown species that is closely related but distinct from P. infestans, P. mirabilis, and P. ipomoeae. To the best of our knowledge, the unknown parent has not yet been collected. We also observed sequence polymorphism among P. andina isolates at three of the four loci, many of which segregate between previously described P. andina clonal lineages. These results provide strong support that P. andina emerged via hybridization between P. infestans and another unknown Phytophthora species also belonging to Phytophthora clade 1c.

AB Selenium (Se) is an essential redox-active trace element with close connections to cancer. Most of Se's biological functions have been attributed to the antioxidant properties of Se-containing proteins. However, the relative contribution of selenoproteins and small Se compounds in cancer protection is still a matter of debate. The tumor suppressor p53 is the most frequently mutated gene in human cancer and is often referred to as the "guardian of the genome". In response to genomic stresses, p53 causes cell cycle arrest to allow time for genomic damage to be repaired before cell division or induces apoptosis to eliminate irreparably damaged cells. Selenoprotein W (SEPW1) is a highly conserved small thioredoxin-like protein required for cell cycle progression. The present work shows that SEPW1 facilitates the G1 to S-phase transition by down-regulating expression of the cyclin-dependent kinase inhibitor p21. SEPW1 controls p21 by modulating levels of the p53 transcription factor, and this is associated with changes in phosphorylation of Ser-33 in p53. More work is needed to identify the mechanism by which SEPW1 regulates phosphorylation of Ser-33 and the kinase or phosphatase enzymes involved. Published by Elsevier Inc.

AB The 1950s drought severely impacted a 1.1 million km(2) area in the central US. This drought, along with the famous 1930s drought, was among the most severe of the 20th century for large areas and is the drought of record for water supply planning in Texas. At the USDA-ARS Riesel Watersheds during the drought, average annual rainfall was reduced 27%, which produced 75% less runoff and 35% less sediment yield. Rainfall intensity during the drought was, however, typically greater than for the non-drought period. Based on long-term data from the Riesel Watersheds, the mean, 75th, 90th, and 95th percentile values of sediment yields on days with measureable soil loss were larger for the drought than non-drought periods. These results reflect the increase in rainfall intensity during the drought but more importantly the increased efficiency of drought rainfall to dislodge and transport sediment, which is attributed to the combined effects of reduced vegetative cover and increased soil erodibility. The potential for high sediment yields during drought periods illustrates the need to consider this landscape vulnerability in long-term planning and assessment and the importance of long-term monitoring to predict water supply impacts. This is especially evident in Texas, which is expected to experience a dramatic increase in population and water demand this century, with a corresponding decrease in reservoir storage capacity due to sedimentation.

TI A Blueberry-Enriched Diet Attenuates Nephropathy in a Rat Model of
Hypertension via Reduction in Oxidative Stress

AB Objective and Background: To assess renoprotective effects of a blueberry-enriched diet in a rat model of hypertension. Oxidative stress (OS) appears to be involved in the development of hypertension and related renal injury. Pharmacological antioxidants can attenuate hypertension and hypertension-induced renal injury; however, attention has shifted recently to the therapeutic potential of natural products as antioxidants. Blueberries (BB) have among the highest antioxidant capacities of fruits and vegetables.
Methods and Results: Male spontaneously hypertensive rats received a BB-enriched diet (2% w/w) or an isocaloric control diet for 6 or 12 weeks or 2 days. Compared to controls, rats fed BB-enriched diet for 6 or 12 weeks exhibited lower blood pressure, improved glomerular filtration rate, and decreased renovascular resistance. As measured by electron paramagnetic resonance spectroscopy, significant decreases in total reactive oxygen species (ROS), peroxynitrite, and superoxide production rates were observed in kidney tissues in rats on long-term dietary treatment, consistent with reduced pathology and improved function. Additionally, measures of antioxidant status improved; specifically, renal glutathione and catalase activities increased markedly. Contrasted to these observations indicating reduced OS in the BB group after long-term feeding, similar measurements made in rats fed the same diet for only 2 days yielded evidence of increased OS; specifically, significant increases in total ROS, peroxynitrite, and superoxide production rates in all tissues (kidney, brain, and liver) assayed in BB-fed rats. These results were evidence of "hormesis'' during brief exposure, which dissipated with time as indicated by enhanced levels of catalase in heart and liver of BB group.
Conclusion: Long-term feeding of BB-enriched diet lowered blood pressure, preserved renal hemodynamics, and improved redox status in kidneys of hypertensive rats and concomitantly demonstrated the potential to delay or attenuate development of hypertension-induced renal injury, and these effects appear to be mediated by a short-term hormetic response.

AB The emerald ash borer (Agrilus planipennis) is an invasive wood-boring beetle that has killed millions of ash trees since its accidental introduction to North America. All North American ash species (Fraxinus spp.) that emerald ash borer has encountered so far are susceptible, while an Asian species, Manchurian ash (F. mandshurica), which shares an evolutionary history with emerald ash borer, is resistant. Phylogenetic evidence places North American black ash (F. nigra) and Manchurian ash in the same clade and section, yet black ash is highly susceptible to the emerald ash borer. This contrast provides an opportunity to compare the genetic traits of the two species and identify those with a potential role in defense/resistance. We used Difference Gel Electrophoresis (DIGE) to compare the phloem proteomes of resistant Manchurian to susceptible black, green, and white ash. Differentially expressed proteins associated with the resistant Manchurian ash when compared to the susceptible ash species were identified using nano-LC-MS/MS and putative identities assigned. Proteomic differences were strongly associated with the phylogenetic relationships among the four species. Proteins identified in Manchurian ash potentially associated with its resistance to emerald ash borer include a PR-10 protein, an aspartic protease, a phenylcoumaran benzylic ether reductase (PCBER), and a thylakoid-bound ascorbate peroxidase. Discovery of resistance-related proteins in Asian species will inform approaches in which resistance genes can be introgressed into North American ash species. The generation of resistant North American ash genotypes can be used in forest ecosystem restoration and urban plantings following the wake of the emerald ash borer invasion.

AB Leptin is a key pleiotropic cytokine involved in regulation of energy homeostasis and immunity in mammals. In channel catfish, the presence of a partial messenger RNA sequence that encodes a leptin-like peptide (LLP) has been identified and investigated. The objectives of the present studies were to clone and characterize full-length catfish LLP gene, examine tissue expression of LLP mRNA, and determine effects of prolonged fasting and exposure to Edwardsiella ictaluri (E. ictaluri), the bacteria that causes enteric septicemia in catfish, on LLP mRNA expression. Full-length catfish LLP gene was sequenced by genome walking and by 5'- and 3'-RACE. Catfish LLP gene contained three exons with the coding region located in exons 2 and 3. The amino acid sequence of the channel catfish LLP shared very low sequence similarities with leptin of other fish species or the mammalian leptin (24-49%). Using real-time polymerase chain reaction, LLP mRNA expression was detected in various tissues including brain, stomach, spleen, heart, liver, and trunk kidney and was especially high in the liver and trunk kidney. Expression of LLP mRNA in liver and brain was similar between fish that were fasted for 30 days and those that received feed daily for 30 days (P>0.10). Expression of LLP mRNA was increased in liver, spleen, and trunk kidney within 48 h post-exposure to E. ictaluri compared to unexposed fish (P<0.05). Based on the results of the current studies, amino acid sequence of catfish LLP is highly dissimilar to mammalian and fish leptin. Unlike in most mammals, catfish LLP expression is independent of energy status. However, the expression of catfish LLP is increased after exposure to pathogenic bacteria, which is similar to mammals. Further investigations are required to clearly define the biological function and regulation of catfish LLP. (C) 2011 Elsevier Inc. All rights reserved.

ID PERVAPORATION
AB We report a thin-film composite (TFC) membrane fabrication method based on transfer of a pre-formed, cured active layer onto a microporous support. The active layer is cast on a polyvinyl alcohol (PVA) water-soluble film and cured, then the active side of the bilayer is placed against the skin side of the microporous support and the water soluble layer is dissolved. This method can be used with supports of relatively high pore size and porosity, thus reducing mass transfer resistance from the support. Ethanol-selective pervaporation from aqueous solution was chosen for the evaluation of the TFC membranes. In comparing results with a 10 mu m polydimethylsiloxane (PDMS) active layer on two supports, a TFC made with a high porosity support showed 47% higher total permeance than that of a TFC made with a low porosity support. While the TFC with the low porosity support showed a selectivity (ratio of ethanol permeance to water permeance, mole basis) of 0.66, the selectivity of the TFC with the high porosity support was 0.76, approaching the selectivity of a thick, unsupported PDMS membrane. ZSM-5/PDMS mixed matrix active layer TFCs were also prepared, and showed significantly enhanced performance compared to unfilled PDMS TFCs. A method for commercial fabrication is proposed.

AB The objective was to investigate measures of cellular innate immune responses among calm and temperamental Brahman bulls in response to handling and transportation. Sixteen Brahman bulls (344 +/- 37 d of age; 271.6 +/- 45.5 kg BW) classified as either calm (n = 8) or temperamental (n = 8) were loaded onto a trailer, transported for 4 h to a novel facility, rested 16 h overnight, and then were returned to their original facility after a 4 h transport. Blood samples were collected immediately prior to (time 0) and at 24, 48, and 96 h after initial loading for analyses of innate immune and blood parameters. Leukocyte counts did not differ (P > 0.05) due to temperament before or after transportation, but neutrophil:mononuclear cell ratios were greater in temperamental bulls compared to calm bulls at 24 h. At 24 h, expression of peripheral neutrophil beta(2)-integrin decreased among all bulls compared with Oh (P < 0.01). Temperamental bulls had greater glucose and cortisol than calm bulls (P < 0.01) at 48 h; whereas calm bulls had elevated neutrophil L-selectin expression, and phagocytic and oxidative burst activity compared with temperamental bulls (P < 0.10) at 48 h. The supernatant collected from endotoxin-stimulated whole blood cultures had greater TNF-alpha concentrations at 48 h than at the other time points (P < 0.05), but no temperament effect was observed (P > 0.05). In contrast, 96 h after initial loading the supernatant TNF-alpha concentrations were lower (P < 0.05) among all cattle. Lastly, transportation increased neutrophil phagocytosis, oxidative burst, and cell adhesion molecule expression 96 h post-transportation and the effect was more pronounced among calm bulls. These data suggest that neutrophils from calm bulls are more likely to resist microbial invasion at 96 h after transportation than neutrophils from temperamental bulls. (C) 2011 Elsevier B.V.

AB Estimates of data uncertainties are required to integrate different observational data streams as model constraints using model-data fusion. We describe an approach with which random and systematic uncertainties in optical measurements of leaf area index [LAI] can be quantified. We use data from a measurement campaign at the spruce-dominated Howland Forest AmeriFlux site for illustrative purposes. We made measurements along two transects (one in a mature stand, one in a recently harvested shelterwood) before sunset on successive days using both the Li-Cor LAI-2000 plant canopy analyzer and digital hemispherical photography (DHP). The random measurement uncertainty (1 sigma) at a given point for a single measurement is about 5% for LAI-2000 and 10% for DHP. These uncertainties are small compared to potential systematic biases due to instrument calibration errors and data processing decisions, which are estimated to be 10-20% for each instrument. Sampling uncertainty (due to the spatial variability along each transect where we conducted our measurements) is an additional, but again relatively small. uncertainty. Assumptions about clumping parameters, for which standard literature values are typically used, remain large sources of uncertainty. This analysis can also be used to develop strategies to reduce measurement uncertainties. (C) 2011 Elsevier B.V. All rights reserved.

AB Parent material has a profound impact on chemical weathering, mineral transformation and chemical denudation. However, there remains a relative paucity of lithosequence studies that directly examine parent material control on pedogenic processes. We sampled a lithosequence of four parent materials (rhyolite, granite, basalt, dolostone/volcanic cinders) under Pinus ponderosa in mesic and ustic soil moisture and temperature regimes of central and southern Arizona, USA to quantify the contribution of parent material to chemical weathering and elemental mass flux. We quantified chemical weathering and mass flux using a combination of quantitative X-ray diffraction and elemental mass balance. Mass flux calculations were confounded by the addition of volcanic cinders in the dolostone soils and addition of eolian materials in both the basalt and dolostone soils. These variations in parent material were accounted for using a combination of refractory element indices and X-ray diffraction. Results indicated significant differences in profile characteristics and chemical weathering among parent materials. Chemical mass loss from the basalt and dolostone soils were balanced or exceeded by addition of eolian materials, leading to positive and highly variable mass fluxes of 14 +/- 48 kg m(-2) and 10 +/- 22 kg m(-2), respectively. Rhyolite and granite soils exhibited large differences in chemical mass flux despite nearly identical elemental and mineralogical compositions of the respective parent materials. Total chemical mass flux from the granite soils averaged - 173 +/- 31 kg m(-2), whereas mass flux from the rhyolite soils was much larger, on the order of -930 +/- 71 kg m(-2). These large differences result from the variation of parent material grain size and bulk density. The data demonstrate strong control of parent material on chemical weathering and mass flux in cool, semiarid forested ecosystems. Published by Elsevier B.V.

AB Surface electrical resistivity tomography (ERT) is recognized as a powerful non-invasive soil survey and monitoring method. Relationships between electrical resistivity (ER) and soil water contents that are needed to infer the spatial distribution of soil moisture from the ERT results, are known to reflect soil properties. However, pedotransfer relationships that relate ER, water content, and basic soil properties other than clay content have not been developed. The objective of this work was to evaluate the improvement in the estimates of ER from soil water contents if soil basic properties are included in the pedotransfer equations. Soil - coarse-loamy, siliceous, mesic Typic (or Aquic) Hapludult - was sampled in 12 locations at ten depths across a 30 x 30-m experimental site. The resistivity was measured in disturbed samples in four-electrode cells. Water content, bulk density, texture, organic carbon, and pH were measured in these samples. The coefficient and the exponent in the power law-dependence of ER on volumetric water content were approximated with linear regressions that included any number of measured soil basic properties as inputs. A total of 1024 regressions were compared using the Akaike information criterion, and the best model was found that provided the best approximation with minimum number of regression terms. Six soil textural classes were encountered in the samples. When no pedotransfer relationships were included, the R(2) of the log-log relationships between ER and water content increased from 0.45 at 10 cm to 0.91 at 190 cm. Splitting the dataset into topsoil and subsoil subsets resulted in favorable pedotransfer relationships with R(2) about 0.85 both in topsoil and subsoil. Bulk density, clay content, sand content and pH appeared to be influential soil properties. Overall, accuracy of relationships between soil electrical resistivity and volumetric water content at ten depths in highly heterogeneous sandy soil could be substantially improved if pedotransfer relationships were established. Future work is needed on the applicability of data obtained on repacked samples to undisturbed soils and on the selection of input variables and evaluation methods for pedotransfer electrical resistivity pedotransfer functions.

AB Shelterwood seed cutting in conjunction with herbicide site preparation has proven effective at regenerating Allegheny hardwood forests, but the long-term impact of this silvicultural system on herbaceous vegetation has not been determined. From 1994 to 2004, we studied the impacts of operational herbicide site preparation using glyphosate plus sulfometuron methyl herbicides in the context of a shelterwood seed cut. Our study took place on 10 partially cut sites on the Allegheny National Forest in northwestern Pennsylvania. Half of each site received herbicide and half did not in a split-plot design with repeated measures. Fences were erected after year six because deer impact had increased. Resilience of individual species and the community were determined using measures of percent cover by species or species groups and indices of diversity and similarity comparing post-treatment to pre-treatment conditions and controls. In the short term, abundance of all species was reduced and there were four fewer species on average in treated areas. No species was eliminated by herbicide across all sites in the long term. Graminoids were more abundant on treated plots after year six. Targeted ferns remained less abundant on treated than control plots after 10 years. Species richness recovered within 4 years following treatment. Shannon Diversity and Shannon Evenness were greater in treated than in control plots over the full study period, but the differences were not significant in any single year. The richness-based Jaccard index of similarity did not differ between control and treatment plots after year two, while relative abundance influenced indices showed significant differences through year eight. Results suggest that herbaceous layer vegetation is resilient to the disturbance created by herbicide-shelterwood treatments. Published by Elsevier B.V.

AB Retrieval of soil moisture content using the vertical and horizontal polarizations of multiple frequency bands on microwave sensors can provide an estimate of vegetation water content (VWC). Another approach is to use foliar-water indices based on the absorption at shortwave-infrared wavelengths by liquid water in the leaves to determine canopy water content, which is then related to VWC. An example of these indices is the normalized difference infrared index (NDII), which was found to be linearly related to canopy water content using various datasets, including data from the Soil Moisture Experiments 2002 and 2005 in central Iowa. Here we compared independent estimates of VWC from WindSat to Moderate resolution Imaging Spectroradiometer (MODIS) NDII over central Iowa from 2003 to 2005. Results showed that there was a linear relationship between the MODIS and WindSat estimates of VWC, although WindSat-retrieved VWC was greater than MODIS-retrieved VWC. WindSat and MODIS have different satellite overpass times and in most climates we expect VWC to vary over a day due to transpiration and plant water stress. However, a sensitivity analysis indicated that the diurnal variation of VWC should not have a significant effect on retrievals of VWC by either method. The results of this study indicated that soil moisture retrievals from microwave sensors may be improved using VWC from optical sensors determined by foliar-water indices and classifications of land cover type.

TI Molecular evolution of Adh and LEAFY and the phylogenetic utility of
their introns in Pyrus (Rosaceae)

AB Background: The genus Pyrus belongs to the tribe Pyreae (the former subfamily Maloideae) of the family Rosaceae, and includes one of the most important commercial fruit crops, pear. The phylogeny of Pyrus has not been definitively reconstructed. In our previous efforts, the internal transcribed spacer region (ITS) revealed a poorly resolved phylogeny due to non-concerted evolution of nrDNA arrays. Therefore, introns of low copy nuclear genes (LCNG) are explored here for improved resolution. However, paralogs and lineage sorting are still two challenges for applying LCNGs in phylogenetic studies, and at least two independent nuclear loci should be compared. In this work the second intron of LEAFY and the alcohol dehydrogenase gene (Adh) were selected to investigate their molecular evolution and phylogenetic utility.
Results: DNA sequence analyses revealed a complex ortholog and paralog structure of Adh genes in Pyrus and Malus, the pears and apples. Comparisons between sequences from RT PCR and genomic PCR indicate that some Adh homologs are putatively nonfunctional. A partial region of Adh1 was sequenced for 18 Pyrus species and three subparalogs representing Adh1-1 were identified. These led to poorly resolved phylogenies due to low sequence divergence and the inclusion of putative recombinants. For the second intron of LEAFY, multiple inparalogs were discovered for both LFY1int2 and LFY2int2. LFY1int2 is inadequate for phylogenetic analysis due to lineage sorting of two inparalogs. LFY2int2-N, however, showed a relatively high sequence divergence and led to the best-resolved phylogeny. This study documents the coexistence of outparalogs and inparalogs, and lineage sorting of these paralogs and orthologous copies. It reveals putative recombinants that can lead to incorrect phylogenetic inferences, and presents an improved phylogenetic resolution of Pyrus using LFY2int2-N.
Conclusions: Our study represents the first phylogenetic analyses based on LCNGs in Pyrus. Ancient and recent duplications lead to a complex structure of Adh outparalogs and inparalogs in Pyrus and Malus, resulting in neofunctionalization, nonfunctionalization and possible subfunctionalization. Among all investigated orthologs, LFY2int2-N is the best nuclear marker for phylogenetic reconstruction of Pyrus due to suitable sequence divergence and the absence of lineage sorting.

AB During dire conditions, the channelling of resources into reproduction ensures species preservation. This strategy of survival through the next generation is particularly important for plants that are unable to escape their environment but can produce hardy seeds. Here, we describe the multiple roles of OXIDATIVE STRESS 2 (OXS2) in maintaining vegetative growth, activating stress tolerance, or entering into stress-induced reproduction. In the absence of stress, OXS2 is cytoplasmic and is needed for vegetative growth; in its absence, the plant flowers earlier. Upon stress, OXS2 is nuclear and is needed for stress tolerance; in its absence, the plant is stress sensitive. OXS2 can activate its own gene and those of floral integrator genes, with direct binding to the floral integrator promoter SOC1. Stress-induced SOC1 expression and stress-induced flowering are impaired in mutants with defects in OXS2 and three of the four OXS2-like paralogues. The autoactivation of OXS2 may be a commensurate response to the stress intensity, stepping up from a strategy based on tolerating the effects of stress to one of escaping the stress via reproduction.

AB The negative effects of climate change are already evident for many of the 25 million coffee farmers across the tropics and the 90 billion dollar (US) coffee industry. The coffee berry borer (Hypothenemus hampei), the most important pest of coffee worldwide, has already benefited from the temperature rise in East Africa: increased damage to coffee crops and expansion in its distribution range have been reported. In order to anticipate threats and prioritize management actions for H. hampei we present here, maps on future distributions of H. hampei in coffee producing areas of East Africa. Using the CLIMEX model we relate present-day insect distributions to current climate and then project the fitted climatic envelopes under future scenarios A2A and B2B (for HADCM3 model). In both scenarios, the situation with H. hampei is forecasted to worsen in the current Coffea arabica producing areas of Ethiopia, the Ugandan part of the Lake Victoria and Mt. Elgon regions, Mt. Kenya and the Kenyan side of Mt. Elgon, and most of Rwanda and Burundi. The calculated hypothetical number of generations per year of H. hampei is predicted to increase in all C. arabica-producing areas from five to ten. These outcomes will have serious implications for C. arabica production and livelihoods in East Africa. We suggest that the best way to adapt to a rise of temperatures in coffee plantations could be via the introduction of shade trees in sun grown plantations. The aims of this study are to fill knowledge gaps existing in the coffee industry, and to draft an outline for the development of an adaptation strategy package for climate change on coffee production. An abstract in Spanish is provided as Abstract S1.

AB Castor has tremendous potential as a feedstock for biodiesel production. The oil content and fatty acid composition in castor seed are important factors determining the price for production and affecting the key fuel properties of biodiesel. There are 1033 available castor accessions collected or donated from 48 countries worldwide in the USDA germplasm collection. The entire castor collection was screened for oil content and fatty acid composition by nuclear magnetic resonance (NMR) and gas chromatography (GC), respectively. Castor seeds on the average contain 48.2% oil with significant variability ranging from 37.2 to 60.6%. Methyl esters were prepared from castor seed by alkaline transmethylation. GC analysis of methyl esters confirmed that castor oil was composed primarily of eight fatty acids: 1.48% palmitic (C16:0), 1.58% stearic (C18:0), 4.41% oleic (C18:1), 6.42% linoleic (C18:2,), 0.68% linolenic (C18:3), 0.45% gadoleic (C20:1), 84.51% ricinoleic (C18:1-IOH), and 0.47% dihydroxystearic (C18:0-2OH) acids. Significant variability in fatty acid composition was detected among castor accessions. Ricinoleic acid (RA) was positively correlated with dihydroxystearic acid (DHSA) but highly negatively correlated with the five other fatty acids except linolenic acid. The results for oil content and fatty acid composition obtained from this study will be useful for end-users to explore castor germplasm for biodiesel production.

AB The main objective of this article was to report a simple, fast, and low cost strategy for the synthesis of micro- and nanocomposites by adding cellulose nanofibers, obtained by acid hydrolysis, and added to hydrogels as reinforcing agents. Specifically, when cellulose nanofibers were added to hydrogels, morphologic analyses showed significant decreases in pore size and formation of three-dimensional well-oriented porous microstructure. It was also observed that cellulose nanoparticles improved the mechanical and structural network properties without negatively impacting their thermal and hydrophilic properties. The value of maximum compressive stress was 2.1 kPa for the PAAm-MC, and it increased to 4.4 kPa when the cellulose nanofiber was incorporated into the hydrogel. By investigation of XRD patterns, it was found that the incorporation of cellulose nanofiber affected the crystallinity of PAAm-MC hydrogels, thus contributing to improvements in mechanical, structural, and hydrophilic properties of the PAAm-MC hydrogels.

AB Fruits of the cultivated eggplant species Solanum melongena and its wild relative Solanum incanum have a high content of hydroxycinnamic acid conjugates, which are implicated in the human health benefits of various fruits and vegetables. Monocaffeoylquinic acid esters, in particular 5-0-(E)-caffeoylquinic acid, are usually predominant in solanaceous fruits and tubers. Two closely related caffeoylquinic acid derivatives with longer C(18) HPLC retention times than those of monocaffeoylquinic acids are minor constituents in cultivated eggplant fruit. In a prior study, the two compounds were tentatively identified as 3-O-acetyl- and 4-O-acetyl-5-O-(E)-caffeoylquinic acids and composed <= 2% of the total hydroxycinnamic acid conjugates in fruit of most S. melongena accessions. It was recently found that the pair of these caffeoylquinic acid derivatives can compose 15-25% of the total hydroxycinnamic acid conjugates in fruits of S. incanum and wild S. melongena. This facilitated C18 HPLC isolation and structural elucidation using (1)H and (13)C NMR techniques and HR-ToF-MS. The isomeric compounds were identified as 3-O-malonyl-5-O-(E)-caffeoylquinic acid (isomer 1) and 4-O-(E)-caffeoyl-5-O-malonylquinic acid (isomer 2). Both exhibited free radical scavenging activity, albeit about 4-fold lower than that of the flavonol quercetin dihydrate. By contrast, the iron chelation activities of isomers 1 and 2, respectively, were about 3- and 6-fold greater than that of quercetin dihydrate. Reports of malonylhydroxycinnamoylquinic acids are rare, and only a few of these compounds have been structurally elucidated using both NMR and MS techniques. To the authors' knowledge, these two malonylcaffeoylquinic acid isomers have not previously been reported.

AB Microbial conversions of unsaturated fatty acids often generate polyhydroxy fatty acids, giving them new properties such as higher viscosity and reactivity. A bacterial strain Pseudomonas aeruginosa (PR3) has been intensively studied to produce mono-, di-, and trihydroxy fatty acids from different 9-cis-monoenoic fatty acids such as oleic acid, ricinoleic acid, and palmitoleic acid. However, from the results and the postulated similar metabolic pathways involved in these transformations, it was assumed that the enzyme system involved in transformation of the mono enoic fatty acid by strain PR3 could utilize fatty acids with different chain lengths and locations of the double bond. In this study was used as a substrate for bioconversion by strain PR3 eicosenoic acid (C20:1, omega-9) containing a singular cis double bond at different positions from the carboxyl end as oleic acid, and it was confirmed that PR3 could produce a novel 9,12-dihydroxy-10(E)-eicosenoic acid (DED) with 6.2% yield from eicosenoic acid. The structure of DED was confirmed using GC-MS, FTIR, and NMR analyses. DED production was maximized at 72 h after the substrate was added to the 24 h culture. Some other nutritional factors were also studied for optimal production of DED.

AB Neotyphodium coenophialum-infected tall fescue contains ergopeptines. Except for interations with biogenic amine receptors (e g, dopamine type-2 receptor, D2R), little, is known about how ergopeptines affect animal metabolism. The effect of ergopeptines on bovine nucleoside transporters (NT) was evaluated using Madin-Darby bovine kidney (MDBK) cells. Equilibrative NT1 (ENT1)-like activity accounted for 94% of total NT activity. Inhibitory competition (IC50) experiments found that this activity was inhibited by both bromocriptine (a synthetic model ergopeptine and D2R agonist) and ergovaline (a predominant ergopeptine of tall fescue). kinetic inhibition analysis indicated that bromocriptine inhibited ENT1-like activity through a competitive and noncompetitive mechanism. Domperidone (a. D2R antagonist) inhibited ENT1 activity more in the presence than in the absence of bromocriptine and displayed an IC50 value lower than that of bromocriptine or ergovaline, suggesting that inhibition was not through D2R-mediated events. These novel mechanistic findings imply that cattle consuming endophyte-infected tall fescue have reduced ENT1 activity and, thus, impaired nucleoside metabolism.

AB The ratio of saturated to unsaturated fatty acids in maize kernels strongly impacts human and livestock health, but is a complex trait that is difficult to select based on phenotype. Map-based cloning of quantitative trait loci (QTL) is a powerful but time-consuming method for the dissection of complex traits. Here, we combine linkage and association analyses to fine map QTL-Pal9, a QTL influencing levels of palmitic acid, an important class of saturated fatty acid. QTL-Pal9 was mapped to a 90-kb region, in which we identified a candidate gene, Zea mays fatb (Zmfatb), which encodes acyl-ACP thioesterase. An 11-bp insertion in the last exon of Zmfatb decreases palmitic acid content and concentration, leading to an optimization of the ratio of saturated to unsaturated fatty acids while having no effect on total oil content. We used three-dimensional structure analysis to explain the functional mechanism of the ZmFATB protein and confirmed the proposed model in vitro and in vivo. We measured the genetic effect of the functional site in 15 different genetic backgrounds and found a maximum change of 4.57 mg/g palmitic acid content, which accounts for similar to 20-60% of the variation in the ratio of saturated to unsaturated fatty acids. A PCR-based marker for QTL-Pal9 was developed for marker-assisted selection of nutritionally healthier maize lines. The method presented here provides a new, efficient way to clone QTL, and the cloned palmitic acid QTL sheds lights on the genetic mechanism of oil biosynthesis and targeted maize molecular breeding.

AB Pest insects harm crops, livestock and human health, either directly or by acting as vectors of disease. The Sterile Insect Technique (SIT) - mass-release of sterile insects to mate with, and thereby control, their wild counterparts - has been used successfully for decades to control several pest species, including pink bollworm, a lepidopteran pest of cotton. Although it has been suggested that genetic engineering of pest insects provides potential improvements, there is uncertainty regarding its impact on their field performance. Discrimination between released and wild moths caught in monitoring traps is essential for estimating wild population levels. To address concerns about the reliability of current marking methods, we developed a genetically engineered strain of pink bollworm with a heritable fluorescent marker, to improve discrimination of sterile from wild moths. Here, we report the results of field trials showing that this engineered strain performed well under field conditions. Our data show that attributes critical to SIT in the field - ability to find a mate and to initiate copulation, as well as dispersal and persistence in the release area - were comparable between the genetically engineered strain and a standard strain. To our knowledge, these represent the first open-field experiments with a genetically engineered insect. The results described here provide encouragement for the genetic control of insect pests.

AB Waterfowl from northwestern Minnesota were sampled by cloacal swabbing for Avian Influenza Virus (AIV) from July - October in 2007 and 2008. AIV was detected in 222 (9.1%) of 2,441 ducks in 2007 and in 438 (17.9%) of 2,452 ducks in 2008. Prevalence of AIV peaked in late summer. We detected 27 AIV subtypes during 2007 and 31 during 2008. Ten hemagglutinin (HA) subtypes were detected each year (i.e., H1, 3-8, and 10-12 during 2007; H1-8, 10 and 11 during 2008). All neuraminidase (NA) subtypes were detected during each year of the study. Subtype diversity varied between years and increased with prevalence into September. Predominant subtypes during 2007 (comprising >= 5% of subtype diversity) included H1N1, H3N6, H3N8, H4N6, H7N3, H10N7, and H11N9. Predominant subtypes during 2008 included H3N6, H3N8, H4N6, H4N8, H6N1, and H10N7. Additionally, within each HA subtype, the same predominant HA/NA subtype combinations were detected each year and included H1N1, H3N8, H4N6, H5N2, H6N1, H7N3, H8N4, H10N7, and H11N9. The H2N3 and H12N5 viruses also predominated within the H2 and H12 subtypes, respectively, but only were detected during a single year (H2 and H12 viruses were not detected during 2007 and 2008, respectively). Mallards were the predominant species sampled (63.7% of the total), and 531 AIV were isolated from this species (80.5% of the total isolates). Mallard data collected during both years adequately described the observed temporal and spatial prevalence from the total sample and also adequately represented subtype diversity. Juvenile mallards also were adequate in describing the temporal and spatial prevalence of AIV as well as subtype diversity.

AB The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae) is endemic to Africa and is the most devastating pest of coffee worldwide. The female bores a hole in the coffee berry and deposits her eggs inside. Upon hatching, larvae feed on the seeds, thus reducing both quality and yields of the marketable product. The coffee berry borer was found in the district of Kona on the island of Hawaii in August 2010 and appears to be restricted to that area.

AB Background: Cotton fiber length is an important quality attribute to the textile industry and longer fibers can be more efficiently spun into yarns to produce superior fabrics. There is typically a negative correlation between yield and fiber quality traits such as length. An understanding of the regulatory mechanisms controlling fiber length can potentially provide a valuable tool for cotton breeders to improve fiber length while maintaining high yields. The cotton (Gossypium hirsutum L.) fiber mutation Ligon lintless-2 is controlled by a single dominant gene (Li(2)) that results in significantly shorter fibers than a wild-type. In a near-isogenic state with a wild-type cotton line, Li(2) is a model system with which to study fiber elongation.
Results: Two near-isogenic lines of Ligon lintless-2 (Li(2)) cotton, one mutant and one wild-type, were developed through five generations of backcrosses (BC(5)). An F(2) population was developed from a cross between the two Li(2) near-isogenic lines and used to develop a linkage map of the Li(2) locus on chromosome 18. Five simple sequence repeat (SSR) markers were closely mapped around the Li(2) locus region with two of the markers flanking the Li(2) locus at 0.87 and 0.52 centimorgan. No apparent differences in fiber initiation and early fiber elongation were observed between the mutant ovules and the wild-type ones. Gene expression profiling using microarrays suggested roles of reactive oxygen species (ROS) homeostasis and cytokinin regulation in the Li(2) mutant phenotype. Microarray gene expression data led to successful identification of an EST-SSR marker (NAU3991) that displayed complete linkage to the Li(2) locus.
Conclusions: In the field of cotton genomics, we report the first successful conversion of gene expression data into an SSR marker that is associated with a genomic region harboring a gene responsible for a fiber trait. The EST-derived SSR marker NAU3991 displayed complete linkage to the Li(2) locus on chromosome 18 and resided in a gene with similarity to a putative plectin-related protein. The complete linkage suggests that this expressed sequence may be the Li(2) gene.

TI Economic Impacts of Non-Native Forest Insects in the Continental United
States

DT Article

AB Reliable estimates of the impacts and costs of biological invasions are critical to developing credible management, trade and regulatory policies. Worldwide, forests and urban trees provide important ecosystem services as well as economic and social benefits, but are threatened by non-native insects. More than 450 non-native forest insects are established in the United States but estimates of broad-scale economic impacts associated with these species are largely unavailable. We developed a novel modeling approach that maximizes the use of available data, accounts for multiple sources of uncertainty, and provides cost estimates for three major feeding guilds of non-native forest insects. For each guild, we calculated the economic damages for five cost categories and we estimated the probability of future introductions of damaging pests. We found that costs are largely borne by homeowners and municipal governments. Wood-and phloem-boring insects are anticipated to cause the largest economic impacts by annually inducing nearly $1.7 billion in local government expenditures and approximately $830 million in lost residential property values. Given observations of new species, there is a 32% chance that another highly destructive borer species will invade the U. S. in the next 10 years. Our damage estimates provide a crucial but previously missing component of cost-benefit analyses to evaluate policies and management options intended to reduce species introductions. The modeling approach we developed is highly flexible and could be similarly employed to estimate damages in other countries or natural resource sectors.

TI Metagenome Plasticity of the Bovine Abomasal Microbiota in Immune

AB Infections in cattle by the abomasal nematode Ostertagia ostertagi result in impaired gastrointestinal function. Six partially immune animals were developed using multiple drug-attenuated infections, and these animals displayed reduced worm burdens and a slightly elevated abomasal pH upon reinfection. In this study, we characterized the abomasal microbiota in response to reinfection using metagenomic tools. Compared to uninfected controls, infection did not induce a significant change in the microbial community composition in immune animals. 16S rRNA gene-based phylogenetic analysis identified 15 phyla in the bovine abomasal microbiota with Bacteroidetes (60.5%), Firmicutes (27.1%), Proteobacteria (7.2%), Spirochates (2.9%), and Fibrobacteres (1.5%) being the most predominant. The number of prokaryotic genera and operational taxonomic units (OTU) identified in the abomasal microbial community was 70.8 +/- 19.8 (mean +/- SD) and 90.3 +/- 2.9, respectively. However, the core microbiome comprised of 32 genera and 72 OTU. Infection seemingly had a minimal impact on the abomasal microbial diversity at a genus level in immune animals. Proteins predicted from whole genome shotgun (WGS) DNA sequences were assigned to 5,408 Pfam and 3,381 COG families, demonstrating dazzling arrays of functional diversity in bovine abomasal microbial communities. However, none of COG functional classes were significantly impacted by infection. Our results demonstrate that immune animals may develop abilities to maintain proper stability of their abomasal microbial ecosystem. A minimal disruption in the bovine abomasal microbiota by reinfection may contribute equally to the restoration of gastric function in immune animals.

TI Does Global Warming Increase Establishment Rates of Invasive Alien

AB Background: The establishment rate of invasive alien insect species has been increasing worldwide during the past century. This trend has been widely attributed to increased rates of international trade and associated species introductions, but rarely linked to environmental change. To better understand and manage the bioinvasion process, it is crucial to understand the relationship between global warming and establishment rate of invasive alien species, especially for poikilothermic invaders such as insects.
Methodology/Principal Findings: We present data that demonstrate a significant positive relationship between the change in average annual surface air temperature and the establishment rate of invasive alien insects in mainland China during 1900-2005. This relationship was modeled by regression analysis, and indicated that a 1 degrees C increase in average annual surface temperature in mainland China was associated with an increase in the establishment rate of invasive alien insects of about 0.5 species year(-1). The relationship between rising surface air temperature and increasing establishment rate remained significant even after accounting for increases in international trade during the period 1950-2005. Moreover, similar relationships were detected using additional data from the United Kingdom and the contiguous United States.
Conclusions/Significance: These findings suggest that the perceived increase in establishments of invasive alien insects can be explained only in part by an increase in introduction rate or propagule pressure. Besides increasing propagule pressure, global warming is another driver that could favor worldwide bioinvasions. Our study highlights the need to consider global warming when designing strategies and policies to deal with bioinvasions.

AB Phage vB_EcoM_CBA120 (CBA120), isolated against Escherichia coli O157:H7 from a cattle feedlot, is morphologically very similar to the classic phage ViI of Salmonella enterica serovar Typhi. Until recently, little was known genetically or physiologically about the ViI-like phages, and none targeting E. coli have been described in the literature. The genome of CBA120 has been fully sequenced and is highly similar to those of both ViI and the Shigella phage AG3. The core set of structural and replication-related proteins of CBA120 are homologous to those from T-even phages, but generally are more closely related to those from T4-like phages of Vibrio, Aeromonas and cyanobacteria than those of the Enterobacteriaceae. The baseplate and method of adhesion to the host are, however, very different from those of either T4 or the cyanophages. None of the outer baseplate proteins are conserved. Instead of T4's long and short tail fibers, CBA120, like ViI, encodes tail spikes related to those normally seen on podoviruses. The 158 kb genome, like that of T4, is circularly permuted and terminally redundant, but unlike T4 CBA120 does not substitute hmdCyt for cytosine in its DNA. However, in contrast to other coliphages, CBA120 and related coliphages we have isolated cannot incorporate H-3-thymidine (H-3-dThd) into their DNA. Protein sequence comparisons cluster the putative "thymidylate synthase" of CBA120, ViI and AG3 much more closely with those of Delftia phage phi W-14, Bacillus subtilis phage SPO1, and Pseudomonas phage YuA, all known to produce and incorporate hydroxymethyluracil (hmdUra).

AB Recent developments in high-throughput sequencing technology have made low-cost sequencing an attractive approach for many genome analysis tasks. Increasing read lengths, improving quality and the production of increasingly larger numbers of usable sequences per instrument-run continue to make whole-genome assembly an appealing target application. In this paper we evaluate the feasibility of de novo genome assembly from short reads (<= 100 nucleotides) through a detailed study involving genomic sequences of various lengths and origin, in conjunction with several of the currently popular assembly programs. Our extensive analysis demonstrates that, in addition to sequencing coverage, attributes such as the architecture of the target genome, the identity of the used assembly program, the average read length and the observed sequencing error rates are powerful variables that affect the best achievable assembly of the target sequence in terms of size and correctness.

TI Localization of DIR1 at the tissue, cellular and subcellular levels

SIGNAL-TRANSDUCTION; FUNCTIONAL-ANALYSIS
AB Background: Systemic Acquired Resistance (SAR) is an induced resistance response to pathogens, characterized by the translocation of a long-distance signal from induced leaves to distant tissues to prime them for increased resistance to future infection. DEFECTIVE in INDUCED RESISTANCE 1 (DIR1) has been hypothesized to chaperone a small signaling molecule to distant tissues during SAR in Arabidopsis.
Results: DIR1 promoter: DIR1-GUS/dir1-1 lines were constructed to examine DIR1 expression. DIR1 is expressed in seedlings, flowers and ubiquitously in untreated or mock-inoculated mature leaf cells, including phloem sieve elements and companion cells. Inoculation of leaves with SAR-inducing avirulent or virulent Pseudomonas syringae pv tomato (Pst) resulted in Type III Secretion System-dependent suppression of DIR1 expression in leaf cells. Transient expression of fluorescent fusion proteins in tobacco and intercellular washing fluid experiments indicated that DIR1's ER signal sequence targets it for secretion to the cell wall. However, DIR1 expressed without a signal sequence rescued the dir1-1 SAR defect, suggesting that a cytosolic pool of DIR1 is important for the SAR response.
Conclusions: Although expression of DIR1 decreases during SAR induction, the protein localizes to all living cell types of the vasculature, including companion cells and sieve elements, and therefore DIR1 is well situated to participate in long-distance signaling during SAR.

AB Coxiella burnetii, a category B biological warfare agent, causes multiple outbreaks of the zoonotic disease Q fever world-wide, each year. The virulent phase I and avirulent phase II variants of the Nine Mile RSA 493 and 439 strains of C. burnetii were propagated in embryonated hen eggs and then purified by centrifugation through Renografin gradients. Total protein fractions were isolated from each phase and subjected to analysis by one-dimensional electrophoresis plus tandem mass spectrometry. A total of 235 and 215 non-redundant proteins were unambiguously identified from the phase I and II cells, respectively. Many of these proteins had not been previously reported in proteomic studies of C. burnetii. The newly identified proteins should provide additional insight into the pathogenesis of Q fever. Several of the identified proteins are involved in the biosynthesis and metabolism of components of the extracellular matrix. Forty-four of the proteins have been annotated as having distinct roles in the pathogenesis or survival of C. burnetii within the harsh phagolysosomal environment. We propose that nine enzymes specifically involved with lipopolysaccharide biosynthesis and metabolism, and that are distinctively present in phase I cells, are virulence-associated proteins.

TI Conversion of deoxynivalenol to 3-acetyldeoxynivalenol in barley-derived
fuel ethanol co-products with yeast expressing trichothecene
3-O-acetyltransferases
SO BIOTECHNOLOGY FOR BIOFUELS

DT Article

AB Background: The trichothecene mycotoxin deoxynivalenol (DON) may be concentrated in distillers dried grains with solubles (DDGS; a co-product of fuel ethanol fermentation) when grain containing DON is used to produce fuel ethanol. Even low levels of DON (<= 5 ppm) in DDGS sold as feed pose a significant threat to the health of monogastric animals. New and improved strategies to reduce DON in DDGS need to be developed and implemented to address this problem. Enzymes known as trichothecene 3-O-acetyltransferases convert DON to 3-acetyldeoxynivalenol (3ADON), and may reduce its toxicity in plants and animals.
Results: Two Fusarium trichothecene 3-O-acetyltransferases (FgTRI101 and FfTRI201) were cloned and expressed in yeast (Saccharomyces cerevisiae) during a series of small-scale ethanol fermentations using barley (Hordeum vulgare). DON was concentrated 1.6 to 8.2 times in DDGS compared with the starting ground grain. During the fermentation process, FgTRI101 converted 9.2% to 55.3% of the DON to 3ADON, resulting in DDGS with reductions in DON and increases in 3ADON in the Virginia winter barley cultivars Eve, Thoroughbred and Price, and the experimental line VA06H-25. Analysis of barley mashes prepared from the barley line VA04B-125 showed that yeast expressing FfTRI201 were more effective at acetylating DON than those expressing FgTRI101; DON conversion for FfTRI201 ranged from 26.1% to 28.3%, whereas DON conversion for FgTRI101 ranged from 18.3% to 21.8% in VA04B-125 mashes. Ethanol yields were highest with the industrial yeast strain Ethanol Red (R), which also consumed galactose when present in the mash.
Conclusions: This study demonstrates the potential of using yeast expressing a trichothecene 3-O-acetyltransferase to modify DON during commercial fuel ethanol fermentation.

AB Domestic ducks are key intermediates in the transmission of H5N1 highly pathogenic avian influenza (HPAI) viruses, and therefore are included in vaccination programs to control H5N1 HPAI. Although vaccination has proven effective in protecting ducks against disease, different species of domestic ducks appear to respond differently to vaccination, and shedding of the virus may still occur in clinically healthy vaccinated populations. In this study we compared the response to vaccination between two common domestic duck species, Pekin (Anus platyrhynchos domesticus) and Muscovy (Canine moschata), which were vaccinated with a commercial inactivated vaccine using one of three different schedules in order to elicit protection to H5N1 HPAI before one month of age. Clear differences in responses to vaccination were observed: the Muscovy ducks developed lower viral antibody titers induced by the same vaccination as Pekin ducks and presented with higher morbidity and mortality after challenge with an H5N1 HPAI virus. When comparing the response to infection in non-vaccinated ducks, differences were also observed, with infected Muscovy ducks presenting a lower mean death time and more severe neurological signs than Pekin ducks. However Pekin ducks had significantly higher body temperatures and higher levels of nitric oxide in the blood at 2 days post challenge than Muscovy ducks, indicating possible differences in innate immune responses. Comparison of the expression of innate immune related genes in spleens of the non-vaccinated infected ducks showed differences including significantly higher levels of expression of RIG-I in Pekin ducks and of IL-6 in Muscovy ducks. Both duck species showed an up-regulation of IFN alpha and MHC-I expression, and a down-regulation of MHC-II. In conclusion, differences in response to infection and vaccination were observed between the two domestic duck species. This information should be taken into account when developing effective vaccination programs for controlling H5N1 HPAI in different species of ducks. Published by Elsevier Ltd.

AB The taxonomic history of the genus Eleodes Eschscholtz is reviewed and the subgenus Melaneleodes Blaisdell redefined based on characters of the female terminalia with Blaps carbonaria Say herein designated as type-species. Eleodes debilis LeConte is removed from Melaneleodes to a new monotypic subgenus, Omegeleodes, based on the female characters. The subgenus Melaneleodes as redefined contains eleven species: anthracinus Blaisdell (new status), carbonarius (Say), halli Blaisdell (new status), humeralis LeConte, neomexicanus Blaisdell, parowanus Blaisdell, pedinoides LeConte, quadricollis Eschscholtz, rileyi Casey, tricostatus (Say) and wenzeli Blaisdell. Eleodes halli Blaisdell is resurrected from synonymy as the oldest available name to replace the homonym Eleodes fuscipilosus Blaisdell 1925 (nec Casey 1890). Eleodes anthracinus Blaisdell, a subspecies of E. quadricollis Eschscholtz is elevated to full species. The subspecies E. quadricollis lustrans Blaisdell is placed in a new combination as Eleodes anthracinus lustrans. Eleodes speculicollis Blaisdell is reduced to subspecific status as E. wenzeli speculicollis, new combination. Eleodes reductus Blaisdell is reduced to a subspecies giving a new combination, E. rileyi reductus. Eleodes coloradensis Blaisdell, Eleodes concinnus Blaisdell and Eleodes quadricollis lassenica Blaisdell, are all submerged as synonyms under Eleodes rileyi Casey. A key to the species is provided along with diagnoses for each with notes on distribution and variation.
Eleodes carbonarius (Say) is redefined to contain a number of variants previously recognized as species or subspecies. Along with the previously recognized subspecies Eleodes carbonarius carbonarius, Eleodes carbonarius omissus LeConte, E. carbonarius knausi Blaisdell, and E. carbonarius soror LeConte, newly recognized subspecific combinations are: E. carbonarius omissoides Blaisdell and E. carbonarius chihuahuaensis Champion. New subspecies described herein are: Eleodes carbonarius nuevoleonensis and E. carbonarius disjunctus. Eleodes mazatzalensis Blaisdell is placed in synonymy under E. carbonarius carbonarius and Eleodes lineatus Blaisdell is placed in synonymy under E. carbonarius chihuahuaensis Champion. A key for the identification of the nine subspecies of Eleodes carbonarius is provided.

AB We sought to visually enhance the attractiveness of a standard black ovitrap routinely used in surveillance of the Asian tiger mosquito, Aedes albopictus, and now being used as lethal ovitraps in Ae. aegypti dengue control programs. Black plastic drinking cups (ovitraps) were visually altered to offer field populations of gravid female Ae. albopictus 6 different oviposition site choices. Trials were conducted at 3 field locations in Gainesville, Orange Park, and Jacksonville, FL, during July-August 2009. A black glossy cup served as the control and was tested against 5 cup choices consisting of white, blue, orange, or black-and-white contrasting patterns (checkered or vertically striped). Means (SE) of eggs collected over 6 wk for each choice were: black 122.53 (9.63) > blue 116.74 (10.74) > checkered 101.84 (9.53) > orange 97.15 (7.95) > striped 84.62 (8.17) > white 81.84 (8.74). Black ovitraps outperformed competing colored and contrasting patterned ovicups with respect to choice from gravid Ae. albopictus seeking artificial oviposition sites.

AB The compound 1-octen-3-ol is a known attractant of some mosquito species, which has led to the hypothesis that olfactory stimulation by this alkenol may be associated with the following structural elements: a terminal site of unsaturation or high electron density; a structural capability for hydrogen bonding, e. g., -OH, -NH2, NHR, NR2, etc.; a saturated hydrocarbon chain of a certain minimum length; and a certain relative distance between the region of high electron density and the alcohol (or other hydrogen-bonding) functional group. Using this logic, we synthesized 20 alkenol analogs based on the octenol double-bonded carbon skeleton. The attraction of female Aedes albopictus and Culex quinquefasciatus to these analogs was compared with 1-octen-3-ol as a standard in semi-field trials. For both species, collections from Mosquito Magnet-X (c) (MMX) suction traps baited with the alkenol analogs in the absence of carbon dioxide were not significantly different from octenol-only baited traps, with the exception of (Z)-3-hepten-1-ol which collected significantly more Ae. albopictus. In the presence of CO2, most of the collections from traps baited with an alkenol were considerably increased for both species but not different from octenol plus CO2, with the exception of Ae. albopictus where (Z)-3-decen-1-ol, (Z)-4-hexen-1-ol, 7-octen-2-ol, and 8-nonen-3-ol significantly depressed trap catches. Although no clearly identifiable structure-activity relationship could be determined from our collected data, we did find that MMX traps baited with carbon dioxide and 4-penten-2-ol or (E)-2-decen-4-ol significantly enhanced Cx. quinquefasciatus collections up to nearly 3-fold compared with octenol plus carbon dioxide.

ID BARRIER TREATMENTS
AB The current Department of Defense pest management system does not provide adequate protection from arthropod disease vectors to personnel deployed in support of US military operations. We hypothesized that military camouflage netting, ubiquitous around living and working areas in current US military operations in Africa and the Middle East, treated with a residual pesticide such as bifenthrin may reduce the presence of biting insects and improve the military pest management system. In this study, we examined the longevity and efficacy of bifenthrin applied to camouflage netting material at the maximum label rate of 0.03 liter formulation (7.9% AI) per 92.9 m(2) against field populations of mosquitoes in southern California in a hot-arid environment similar to regions of Iraq, Afghanistan, and the Horn of Africa. We showed that bifenthrin treatment of camouflage netting was effective at reducing mosquito populations, predominantly Psorophora columbiae and Aedes vexans, by an average of up to 46% for 56 days, and could cause as much as 40% mortality in Culex quinquefasciatus in laboratory bioassays for nearly 2 months postapplication. These population reductions could translate to commensurate reductions in risk of exposure to mosquito-borne pathogens, and could potentially be effective against sand flies and filth flies.

TI Manufacturing Vegetable Oil Based Biodiesel: An Engineering Management
Perspective
SO EMJ-ENGINEERING MANAGEMENT JOURNAL
LA English
DT Article
DE Biodiesel; Engineering Economics; Alternative Energy
AB The search for alternative fuels has increased over the past years. In an era of high government subsidies for alternative fuel production, engineering managers will be tasked with evaluating the economic benefits of these proposed alternatives. This research was an exploratory process that examined biodiesel manufacturing as a potential alternative for cottonseed oil mills that could furnish an outlet for their product if their current market shrinks. The analysis was performed as possible future investment by an existing company with a no debt scenario. The cost modeling indicates that under current market conditions, cottonseed oil is not a viable alternative to traditional fossil fuels. With the expected wholesale price of $0.91 per liter of bio-diesel and a production cost of $1.28 per liter, the current feasibility of the operation is questionable without the inclusion of governmental subsidies.

AB Systemic acquired resistance (SAR), which results in enhanced defense mechanisms in plants, can be elicited by virulent, and avirulent strains of pathogens including nematodes. Recent studies of nematode reproduction strongly suggest that Meloidogyne incognita and Rotylenchulus reniformis induce SAR in cotton, but biochemical evidence of SAR was lacking. Our objective was to determine whether infection of cotton by M. incognita and R. reniformis increases the levels of P-peroxidase, G-peroxidase, and catalase enzymes which are involved in induced resistance. A series of greenhouse trials was conducted; each trial included six replications of four treatments applied to one of three cotton genotypes in a randomized complete block design. The four treatments were cotton plants inoculated with i) R. reniformis, ii) M. incognita, iii) (Actigard), and iv) a nontreated control. Experiments were conducted on cotton genotypes DP 0935 B2RF (susceptible to both nematodes), LONREN-1 (resistant to R. reniformis), and M-I 20 RNR (resistant to M. incognita), and the level of P-peroxidase. G-peroxidase, and catalase activity was measured before and 2, 4, 6,10, and 14 d after treatment application. In all cotton genotypes, activities of all three enzymes were higher ( P <= 0.05) in leaves of plants infected with M. incognita and R. reniformis than in the leaves of control plants, except that M. incognita did not increase catalase activity on LONREN-1. Increased enzyme activity was usually apparent 6 d after treatment. This study documents that infection of cotton by M. incognita or R. reniformis increases the activity of the enzymes involved in systemic acquired resistance; thereby providing biochemical evidence to substantiate previous reports of nematode-induced SAR in cotton.

AB Systemic acquired resistance (SAR) can be elicited by virulent anti avirulent pathogenic strains and SAR against plant-parasitic nematodes has been documented. Our objective was to determine whether co-infection of cotton by Meloidogyne incognita and Rotylenchulus reniformis affects the population level of either nematode compared to infection by each species individually. Split-root trials were conducted in which plants were inoculated with i) reniformis only, ii) M. incognita only, iii) both R. reniformis and M. incognita, or iv) no nematodes. Half of the root system was inoculated with R. reniformis or M. incognita on day 0 and the other half with M. incognita or R. reniformis on day 0 or day 14 depending on the experiment. Experiments were conducted on cotton cultivar DP 0935 B2RE (susceptible to both nematodes), LONREN-1 (germplasm line resistant to R. reniformis), and M-120 RNR (germplasm line resistant to M. incognita), and tests were terminated 8 wk after the last inoculation. Both soil (vermiform) and roots (egg) extracted from each half of the root system to determine the total nematode population levels, and root galling was rated on a 0 to 10 scale. Mixed models analysis and comparison of least squares means indicated no differences in root galling (except on LONREN-1) or population levels when the two nematode species were introduced on the same day. When M. incognita was introduced 14 d after R. reniformis, reduction in galling (36% on DP 0935 and 33% on LONREN-1) and M. incognita population levels (35% on DP 0935 and 45% on LONREN-1) were significant (P <= 0.05). When R. reniformis was inoculated 14 d after M. incognita, reduction in R. reniformis population levels (18% on DP 0935 and 26% on M-120) were significant. This study documents for the first time that infection of cotton by a nematode can elicit SAR to another nematode species.

AB Microplot experiments were conducted over two years (four growing seasons) to evaluate Meloidogyne incognita resistance in rootstocks used for grafted tomato (Solanum lycopersicum), muskmelon (Cucumis melo), and watermelon (Citrullus lunatics). Three tomato rootstocks; 'TX301', 'Multifort', and 'Aloha', were tested in addition to the nongrafted scion, 'Florida-47'. TWO muskmelon rootstocks; Cucumis metliferus and 'Tetsukabuto (Cucurbita maxima X Cucurbita moschata) were evaluated with the nongrafted scion 'Athena', Two watermelon rootstocks included 'Emphasis', a lagenaria-type, and an interspecific squash hybrid ;StrongTosa', which were grafted to the scion 'TriX Palomar' and planted only in the second year Microplots were infested with M. incognita eggs in September each year. Tomatoes were planted in September followed by melons in March. In both years of the study, M. incognita. juveniles (J2) in soil were similar among all tomato rootstocks, but numbers in roots were higher in the nongrafted Florida 47 than in all grafted rootstocks. In muskmelon only C. metuliferus rootstock reduced galling in nematode infested soil. Tetsukabuto did not reduce numbers of M. incognita J2 in either soil or roots either year. There were no differences in nematode numbers, galling, or Plant growth parameters among the watermelon rootstocks tested. The use of resistant rootstocks has great potential for improving nematode control in the absence of soil fumigants.

AB Two field trials were conducted between 2008 and 2010 in Maryland to evaluate the ability of an Italian ryegrass (IR) (Lolium multiflorum) cover crop to reduce populations of plant-parasitic nematodes while enhancing beneficial nematodes, soil mites and arthropods in the foliage of a no-till soybean (Glycine max) planting. Preplant treatments were: 1) previous year soybean stubble (SBS); and 2) herbicide-killed IR cover crop + previous year soybean stubble (referred to as IR). Heterodera glycines population densities were very low and no significant difference in population densities of glycines or Pratylenchus spp. were observed between IR and SBS. Planting of IR increased abundance of bacterivorous nematodes in 2009. A reverse trend was observed in 2010 where SBS had higher abundance of bacterivorous nematodes and nematode richness at the end of the cover cropping period. Italian ryegrass also did not affect insect pests on soybean foliage. However, greater populations of spiders were found on soybean foliage in IR treatments during both field trials. Potential causes of these findings are discussed.

AB Laboratory-based methods to test egg viability include staining with Meldola's Blue and/or juvenile (J2) hatching assays using potato root diffusate (PRD). These two methods have not been tested under identical conditions to directly compare their assessments of Globodera egg viability. Using two bioassay strategies, cysts from a Glabodera sp. population found in Oregon were subjected to both viability assessment methods. In strategy one, intact cysts were first stained with Meldola's Blue (primary staining) and eggs were then transferred to PRD (secondary hatching). In the second strategy, intact cysts were exposed to PRD (primary hatching) and then unhatched eggs were transferred to Meldola's Blue (secondary staining). Two different cohorts of cysts were evaluated using these experimental strategies: cohort I was comprised Of cysts produced on potato in the greenhouse that exhibited low hatch when exposed to PRD and cohort 2 consisted of field-collected cysts whose eggs yielded significant hatch when exposed to PRD Percentage viability was calculated and is expressed as the number of hatched J2 or unstained eggs/total number of eggs within a cyst. With field-produced cysts, primary staining with Meldola's Blue and hatching with PRD produced similar viability estimates, with averages of 74.9% and 76.3%, respectively. In contrast, with greenhouse-produced cysts the two methods yielded much lower and unequal estimates 32.4% to 2.2%, respectively for primary hatching and staining methods. In addition, J2 hatch from Unstained (viable) greenhouse-produced eggs was 13.7% after secondary exposure to PRD compared to 61.5% for field-produced eggs. The majority of eggs remaining unhatched after primary exposure to PRD (> 87%) stained with Meldola's Blue regardless of cyst cohort. Staining with Meldola's Blue provided a conservative assessment of egg viability compared to hatch assay with PRD regardless of diapause.

AB The plum curculio, Conotrachelas nenuphar, is a major pest of stone and pome fruit (e.g., apples, pears, peaches, cherries, etc.). Entomopathogenic nematodes (Steinernema spp. and Heterorhabditis spp.) may be used to control the larval stage of C. nenuphar following fruit drop. Indeed, certain entomopathogenic nematodes species have previously been shown to be highly effective in killing C. nenuphar larvae in laboratory and field trials. In field trials conducted in the Southeastern, USA, Steinernema riobrave has thus far been shown to be the most effective species. However, due to lower soil temperatures, other entomopathogenic nematode strains or species may be more appropriate for use against C. nenuphar in the insect's northern range. Thus, the objective of this study was to conduct a broad screening of entomopathogenic nematodes. Under laboratory conditions, we determined the virulence of 13 nematode strains (comprising nine species) in two different soils (a loam and clay-loam) and three different temperatures (12 C, 18 C, and 25 C). Superior virulence was observed in S. feltiae (SN strain), S. rarum (17 C&E strain), and S. riobrave (355 strain). Promising levels of virulence were also observed in others including H. indica (HOM1 strain), H. bacteriophora (Oswego strain), S. kraussei, and S. carpocapsae (Sal strain). All nematode treatments were affected by temperature with the highest virulence observed at the highest temperature (25 degrees C).

AB Scope: Fumonisin B1 (FB1) is a mycotoxin found in maize and maize-based foods. It causes animal diseases and is a suspected risk factor for cancer and birth defects in humans. Extrusion cooking reduces FB1 concentrations in maize however toxicity caused by unknown degradation or FB1-matrix reaction products might persist.
Methods and results: To test the efficacy of extrusion to reduce FB1 toxicity, Fusarium verticillioides fermented corn (= maize) grits (Batch-1=9.7 ppm FB1; Batch-2=50 ppm FB1) were extruded without (Batch-1E; Batch-2E) or with 10% glucose supplementation (Batch-1EG; Batch-2EG). FB1 concentrations were reduced 64% (Batch-2E) to 94% (Batch-1EG) after cooking. When the uncooked and processed grits were fed (50% w/w in rodent chow) to rats for up to 8 weeks, FB1 intakes averaged 354, 103, and 25.1 cg/kg body weight/day for Batch-1, Batch-1E and Batch-1EG and 1804, 698, and 222 cg/kg body weight/day for the Batch-2, Batch-2E and Batch-2EG, respectively. Nephrotoxicity including apoptotic lesions and elevated sphingoid base concentrations decreased in a dose-dependent manner in groups fed Batch-1, Batch-1E, Batch-2, Batch-2E, or Batch-2EG and was absent in the Batch-1EG group.
Conclusion: Extrusion cooking, especially with glucose supplementation, is potentially useful to reduce FB1 concentrations and toxicity of FB1-contaminated maize.

AB We consider applying Bayesian Variable Selection Regression, or BVSR, to genome-wide association studies and similar large-scale regression problems. Currently, typical genome-wide association studies measure hundreds of thousands, or millions, of genetic variants (SNPs), in thousands or tens of thousands of individuals, and attempt to identify regions harboring SNPs that affect some phenotype or outcome of interest. This goal can naturally be cast as a variable selection regression problem, with the SNPs as the covariates in the regression. Characteristic features of genome-wide association studies include the following: (i) a focus primarily on identifying relevant variables, rather than on prediction; and (ii) many relevant covariates may have tiny effects, making it effectively impossible to confidently identify the complete "correct" subset of variables. Taken together, these factors put a premium on having interpretable measures of confidence for individual covariates being included in the model, which we argue is a strength of BVSR compared with alternatives such as penalized regression methods. Here we focus primarily on analysis of quantitative phenotypes, and on appropriate prior specification for BVSR in this setting, emphasizing the idea of considering what the priors imply about the total proportion of variance in outcome explained by relevant covariates. We also emphasize the potential for BVSR to estimate this proportion of variance explained, and hence shed light on the issue of "missing heritability" in genome-wide association studies. More generally, we demonstrate that, despite the apparent computational challenges, BVSR can provide useful inferences in these large-scale problems, and in our simulations produces better power and predictive performance compared with standard single-SNP analyses and the penalized regression method LASSO. Methods described here are implemented in a software package, pi-MASS, available from the Guan Lab website http://bcm.edu/cnrc/mcmcmc/pimass.

AB Objective: To examine the agreement between perceptions, behaviors, and ability to purchase healthful food in the Lower Mississippi Delta (LMD).
Design: A regional food store survey of healthful food options in supermarkets, small/medium stores, and convenience stores. Focus group discussions were conducted on shopping perceptions and behaviors.
Setting: Counties in Arkansas, Louisiana, and Mississippi.
Participants: Eighty-one LMD residents, 18-60+ years of age.
Main Outcome Measure: Perceptions of healthful food and ability to acquire these food items across store types.
Analysis: Focus group data were analyzed using thematic coding. Summary food store statistics were weighted, and estimates were constructed using SUDAAN 9. Data triangulation was achieved by comparing focus group findings with food availability data.
Results: A majority (> 85%) of supermarkets had selected vegetables, breads, and cereals perceived as healthful, whereas availability was limited in small to medium grocery stores and convenience stores. Skim milk, perceived as healthful, was limited in all store types.
Conclusions and Implications: Limited availability and perceived costs of healthful food in the LMD influenced purchasing behaviors. Attitudes and perceptions should be incorporated into intervention development to improve food choices in conjunction with increasing the availability of healthful food in the LMD.

The eight previously described species are: Delottococcus aberiae (De Lotto), D. confusus (De Lotto), D. elisabethae (Brain), D. euphorbiae (Ezzat & McConnell), D. phylicus (De Lotto), D. proteae (Hall), D. quaesitus (Brain), and D. trichiliae (Brain). Adult females of all species are described and illustrated and a key for their identification is presented. In the past, specimens determined as D. elisabethae have been recorded from citrus and other hosts, but these appear to be misidentifications of D. aberiae. Delottococcus elisabethae is only known from the original collection. As invasive species, D. confusus is reported from California and Hawaii, D. aberiae from Spain, and D. euphorbiae from France, Italy, and Sicily.

AB Cyanobacteria and algae are problematic in California rice fields that are typically shallow and have high nutrient levels, providing ideal growing conditions. Nostoc spongiaeforme is a problem because extensive floating mats dislodge rice seedlings or smother them when the mats accumulate in windward areas. There is little published information on growth requirements for N. spongiaeforme. We grew N. spongiaeforme in BG-11 medium at 24 combinations of light (22, 87, 162, and 400 mu M m(-2) s(-1)) and temperatures (10 degrees C, 15 degrees C, 20 degrees C, 25 degrees C, 30 degrees C, and 35 degrees C). Results were summarized as a quadratic equation relating light and temperature to growth and indicate that optimal growth occurred at 26 degrees C and 227 mu M m(-2) s(-1) of light. Thus, N. spongiaeforme grows well at water temperatures and light levels similar to those measured in rice fields during the critical 30 days following initial flooding of the field.

AB Domestic sheep in Kazakhstan may provide an interesting source of genetic variability due to their proximity to the center of domestication and the Silk Route. Additionally, those breeds have never been compared to New World sheep populations. This report compares genetic diversity among five Kazakhstan (KZ) and 13 United States (US) sheep breeds (N = 442) using 25 microsatellite markers from the FAO panel. The KZ breeds had observed and expected measures of heterozygosity greater than 0.60 and an average number of alleles per locus of 7.8. In contrast, US sheep breeds had observed heterozygosity ranged from 0.37 to 0.62 and had an average number of alleles of 5.7. A Bayesian analysis indicated there were two primary populations (K = 2). Surprisingly, the US breeds were near evenly split between the two clusters, while all of the KZ breeds were placed in one of the two clusters. Pooling breeds within country of sample origin showed KZ and US populations to have similar levels of expected heterozygosity and the average number of alleles per locus. The results of breeds pooled within country suggest that there was no difference between countries for these diversity measures using this set of neutral markers. This finding suggests that populations' geographically isolated from centers of domestication can be more diverse than previously thought, and as a result, conservation strategies can be adjusted accordingly. Furthermore, these results suggest there may be limited need for countries to alter the protocols for trade and exchange of animal genetic resources that are in place today, since no one population has a unique set of private alleles.

Five species and two varieties of Manihot, besides two species of the genus Croton, used as the out-group, were analyzed by using 20 oligonucleotide (Olii) ISSR UBC primers. To analyze the similarity index between species and accessions, the Jaccard and simple matching coefficients were used. The 20 Olii tested were highly polymorphic in all species analyzed, and 89.7% of the loci were polymorphic. A higher genetic variability is observed among different species of Manihot, such as M. dichotoma var. undulata and M. caerulescens, than among individuals of the same species, such as M. dichotoma and M. dichotoma var. undulata.

AB The taxonomic history of anamorphic species attributed to Penicillium subgenus Biverticillium is reviewed, along with evidence supporting their relationship with teleomorphic species classified in Talaromyces. To supplement previous conclusions based on ITS, SSU and/or LSU sequencing that Talaromyces and subgenus Biverticillium comprise a monophyletic group that is distinct from Penicillium at the generic level, the phylogenetic relationships of these two groups with other genera of Trichocomaceae was further studied by sequencing a part of the RPB1 (RNA polymerase II largest subunit) gene. Talaromyces species and most species of Penicillium subgenus Biverticillium sensu Pitt reside in a monophyletic clade distant from species of other subgenera of Penicillium. For detailed phylogenetic analysis of species relationships, the ITS region (incl. 5.8S nrDNA) was sequenced for the available type strains and/or representative isolates of Talaromyces and related biverticillate anamorphic species. Extrolite profiles were compiled for all type strains and many supplementary cultures. All evidence supports our conclusions that Penicillium subgenus Biverticillium is distinct from other subgenera in Penicillium and should be taxonomically unified with the Talaromyces species that reside in the same clade. Following the concepts of nomenclatural priority and single name nomenclature, we transfer all accepted species of Penicillium subgenus Biverticillium to Talaromyces. A holomorphic generic diagnosis for the expanded concept of Talaromyces, including teleomorph and anamorph characters, is provided. A list of accepted Talaromyces names and newly combined Penicillium names is given. Species of biotechnological and medical importance, such as P funiculosum and P marneffei, are now combined in Talaromyces. Excluded species and taxa that need further taxonomic study are discussed. An appendix lists other generic names, usually considered synonyms of Penicillium sensu late that were considered prior to our adoption of the name Talaromyces.

AB The present study aimed to describe the bacterial community present at an anaerobic up flow bioreactor with ANAMMOX activity, inoculated with the sludge from the anaerobic pond of a swine slurry treatment system. The description was based on the molecular DNA techniques using primers for amplification of complete 16S rRNA gene and also new primers to amplify smaller fragments from 16S rRNA. During the bioreactor operation time, the bacterial community changed significantly, increasing the nitrogen removal efficiency, reaching after 500 days a removal rate of 94%. The complete PCR amplification of 16S rRNA gene generated 17 clones, where three presented similarity with Candidatus Jettenia asiatica (97%), twelve with Janthinobacterium (99%) and two with uncultured clones. The PCR amplification of 436 base pairs had generated 12 clones, of which eight presented 96-100% similarity with Candidatus Anammoxoglobus propionicus, Planctomycete KSU-1 and one with Pseudomonas sp. (99%) and three with uncultured clones.

AB Hypogymnia imshaugii is one of the most common, conspicuous and morphologically variable epiphytic lichens of the Pacific coastal states and provinces. The species varies greatly in morphology and chemistry, suggesting multiple closely related species or one or more phenotypically plastic species. We sought to determine whether additional ecologically meaningful species might be present within the H. imshaugii complex. Improving our species concepts could potentially improve ecological inferences based on community sampling. Three relatively well-defined genetic groups and one residual group in the H. imshaugii complex were detected with haplotype networks based on the ITS locus; however, phylogenetic reconstructions on combined ITS, mtSSU, GPD1 and TEF1 loci did not reflect this pattern. At present, we have insufficient evidence to support defining any of these groups as new taxa. The four major chemotypes in H. imshaugii differed in frequency among the genetic groups. None of the genetic groups was, however, qualitatively uniform in chemotype. Only one chemotype occurred in a single genetic group, but several chemotypes occurred in that group. While broadly sympatric, each chemotype had a distinct geographic distribution, and each chemotype showed its own relationship to climate, as shown by regression of occurrences of chemotypes against climatic variables. The genetic variation detected within H. imshaugii did not correspond to geographic variation in morphology, chemistry, or climate. Within the broader H. imshaugii complex, we recommend treating H. amplexa as a synonym of H. imshaugii unless it can be more distinctly separated from the clinal variation in morphology, chemistry, or DNA sequences. In contrast to H. amplexa, however, H. inactiva and H. gracilis are both easily separated morphologically from H. imshaugii and do not intergrade with it.

AB We examined rates of late-season parasitism of larvae of the wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), by native species of Brucon F. (Hymenoptera: Braconidae) over 8 years in Montana and North Dakota, United States of America. We found that rates of parasitism of larvae in diapause chambers reached a maximum of 46%, exceeding the previously reported maximum of 2.5% in 75% of sites and years examined. In contrast to previous work, our results demonstrate that C. cinctus larvae are suitable hosts for braconid parasitoids, even after the formation of diapause chambers, and suggest that parasitism rates may be underestimated if stems are sampled prior to harvest.

AB Planting winter cover crops into corn-soybean rotations is a potential approach for reducing subsurface drainage and nitrate-nitrogen (NO(3)-N.) loss. However, the long-term impact of this practice needs investigation. We evaluated the RZWQM2 model against comprehensive field data (2005-2009) in Iowa and used this model to study the long-term (1970-2009) hydrologic and nitrogen cycling effects of a winter cover crop within a corn-soybean rotation. The calibrated RZWQM2 model satisfactorily simulated crop yield, biomass, and N uptake with percent error (PE) within +/- 15% and relative root mean square error (RRMSE) <30% except for soybean biomass and rye N uptake. Daily and annual drainage and annual NO(3)-N loss were simulated satisfactorily, with Nash-Sutcliffe efficiency (NSE) >0.50, ratio of RMSE to standard error (RSR) <0.70, and percent bias (PBIAS) within +/- 25% except for the overestimation of annual drainage and NO(3)-N in CTRL2. The simulation in soil water storage was unsatisfactory but comparable to other studies. Long-term simulations showed that adding rye as a winter cover crop reduced annual subsurface drainage and NO(3)-N loss by 11% (2.9 cm) and 22% (11.8 kg N ha(-1)), respectively, and increased annual ET by 5% (2.9 cm). Results suggest that introducing winter rye cover crops to corn-soybean rotations is a promising approach to reduce N loss front subsurface drained agricultural systems. However, simulated N immobilization under the winter cover crop was not increased, which is inconsistent with a lysimeter study previously reported in the literature. Therefore, further research is needed to refine the simulation of immobilization in cover crop systems using RZWQM2 under a wider range of weather conditions.

AB The Penman-Monteith (P-M) method suggested by the Food Agricultural Organization in irrigation and drainage paper 56 (FAO-56 P-M) was used in the Soil and Water Assessment Tool's (SWAT) water balance simulation at the outlet of an experimental watershed in Sicily, Italy. A sensitivity analysis determined that the model was more sensitive to this potential evapotranspiration (PET) parameter than to the other six parameters impacting surface runoff in this small Mediterranean watershed. The FAO-56 P-M method was compared to the three existing SWAT PET methods from 1997 to 2003. The watershed's water balance was more realistically simulated by the FAO-56 P-M method than by the other PET methods. The traditional P-M method incorporated into SWAT overestimated total (surface and base flow) runoff volumes observed during the entire period by approximately 50%; however, total runoff volumes were underestimated by only 17% when the FAO-56 P-M method was used. The surface runoff simulation results using the FAO-56 P-M PET equation for calculating daily values was sufficient at the monthly time interval (Nash-Sutcliffe efficiency >0.75) during the calibration and validation periods. The incorporation of the FAO-56 P-M method has broadened the SWAT model's applicability to watersheds that are in semi-arid environments with high-intensity, short-duration rainfall events.

AB Spatial variation of soil water affects crop performance, fertilizer use efficiencies, and other important economic and environmental factors. Soil water storage could be increased and field variability reduced by residue management practices such as no tillage (NT), as surface residues can retain more snow, enhance water infiltration, and reduce evaporation as compared to conventional tillage (CT). Our objectives were to evaluate the residue effects on snow distribution and the spatial variation of soil water storage for two adjacent fields near Pullman, Washington: one under NT, and the other under CT The fields were surveyed during the winter and spring of 2007-2008 to assess topographic variations in snow depth, snow water equivalent (SWE), and soil water storage. Standing stubble under NT retained 10 to 20 cm more snow on ridge tops and steeply sloped ground than CT, and the snowpack was distributed more evenly with less spatial variation. SWE followed the same pattern of larger spatial variation in CT than in NT Soil water (0 to 1.5 m) in the spring was lowest for ridge tops and highest in valleys for NT and CT Under NT, however, soil water varied less across different field locations than under CT, and overall water storage was 60, 29, and 13 mm more for NT than CT on ridge top, south slope, and valley locations, respectively. Although many factors can contribute to the spatial variation of soil water, standing wheat residue under NT retained more snow on ridge tops and steeply sloped areas reduced soil water spatial variation, and increased soil water recharge.

AB In this study, we conducted simulated spray irrigation events of dairy wastewater to assess the impact of pressure and sprinkler type on post-sprinkler culturable microorganism concentrations. Dairy wastewater was sampled before and after it was pumped through sprinklers typically used on center-pivot irrigation systems. Three different sprinklers types were used at three different operating pressures to give a range of water drop sizes. The microorganisms quantified in this study were total coliforms, Escherichia coli, Clostridium perfringens, heterotrophic bacteria, and coliphages. In most cases, the pre- and post-sprinkler concentrations were determined to be statistically similar; suggesting that culturable viability was not affected when wastewater flowed through these sprinklers. When an impact was found to occur, there was usually an increase in the post-sprinkler microorganism concentration. While this increase can be attributed to the disruption of microbial aggregates during the spraying process, there was no apparent relationship with pressure setting or spray plate. Understanding impacts at the sprinkler level should be considered an integral part of the dispersion modeling process, as it may influence the number of viable microorganisms that become aerosolized during pressurized irrigation events.

AB This article introduces a special collection of 16 research articles on new developments and applications of the Soil and Water Assessment Tool (SWAT) to address various environmental issues at a range of geographic and temporal scales. Highlights include addition of a subdaily erosion and sediment transport algorithm, a biozone module, and a new algorithm for shallow water table depth. Model applications include climate change impact assessments, model adaptation to regional environmental conditions, watershed-scale soil erosion assessments, and linkages to other models. A summary of reported model performance indicates that 85% of daily flow calibration statistics reported in this collection were satisfactory or better, with very good performance in four of the 20 calibration results and in three of the 19 validation results. Details of reported model parameters for calibration of flow and water quality constituents are provided for other SWAT modelers. This collection builds upon a previous ASABE 2010 SWAT Special Collection, demonstrating continued developments to enhance SWAT's capabilities and highlighting SWAT's continued expansion in international applications, especially in Asia.

AB New Soil and Water Assessment Tool (SWAT) algorithms for simulation of stormwater best management practices (BMPs) such as detention basins, wet ponds, sedimentation filtration ponds, and retention irrigation systems are under development for modeling small/urban watersheds. Modeling stormwater BMPs often requires time steps as small as minutes to realistically capture the instantaneous flow and sediment load coming from upland areas. SWAT2005 uses the Modified Universal Soil Loss Equation (MUSLE) for modeling upland erosion and sediment load. The MUSLE model is an empirical soil loss equation, which was formulated based on field observations rather than theoretically derived relationships to predict long-term average soil loss. This article presents modified physically based erosion models in SWAT for seamless modeling of erosion processes with the recently developed sub-hourly flow models. In the new algorithms, splash erosion is calculated based on the kinetic energy delivered by raindrops, adapted from the European Sod Erosion Model, and overland flow erosion is estimated using a physically based equation adapted from the Areal Nonpoint-Source Watershed Environment Response Simulation (ANSWERS) model. The Yang model and the Brownlie model were also modified for in-stream sediment muting. The SWAT model with the modified sub-daily sediment algorithms was calibrated and validated each for a one-year period at 15 min intervals with measured data from the USDA-ARS Riesel watersheds in Texas. Results show that SWAT with the sub-daily algorithms performed as well or better in terms of sediment yield prediction than SWAT with the current daily output structure. In addition, SWAT (sub-daily) was able to adequately represent the timing, peak, and duration of sediment transport events. Thus, this initial evaluation indicates that the new sub-daily flow and sediment structure in SWAT is a promising tool for water quality assessment studies in small watersheds or urban watersheds where sub-daily process are so important to quantify.

AB Onsite wastewater systems (OWSs) are a significant source of nonpoint-source pollution to surface and groundwater in both rural and suburban settings. Methods to quantify their effect are therefore important. The mechanics of OWS biogeochemical processes are well studied. However, tools for their assessment, especially at the watershed scale, are limited. As part of this work, modeling capabilities were developed within the Soil Water Assessment Tool (SWAT) such that OWSs and their subsequent environmental impacts can be evaluated A case study was initiated on the Hoods Creek watershed in North Carolina to test the new SWAT algorithms. Included were: (1) field-scale simulations of groundwater quantity (water table height) and quality (N, P), (2) Monte Carlo evaluations of OWS service life to evaluate suggested calibration parameters, and (3) assessments of watershed-scale pollutant loadings within the model. Results were then analyzed at both the field and watershed scales. The model performed well in predicting both site groundwater table levels (R(2) = 0.82 and PBIAS = -0.8%) and NO(3)-N concentration in the groundwater (R(2) = 0.76, PBIAS = 2.5%). However, the performance for PO(4)-P simulations was less reliable due to difficulty in representing the mobility of soluble P in the soil. An advanced P algorithm is recommended to address the sophisticated physiochemical properties of soil particles and improve the model's performance.

TI SHALLOW WATER TABLE DEPTH ALGORITHM IN SWAT: RECENT DEVELOPMENTS

ID MODEL; UNCERTAINTY; STREAMFLOW
AB Knowledge of the shallow water table depth (wtd) is crucial in many studies, including determination of optimum irrigation and drainage management systems for agricultural production, farm machine trafficability, and water quality due to agricultural chemical transport and soil salinity. Therefore, it is essential for hydrologic models to accurately simulate wtd. A shallow wtd algorithm, herein called the modified DRAINMOD approach, that relates drainage volume (vol) to wtd, was recently incorporated into the Soil and Water Assessment Tool (SWAT) model. In the modified DRAINMOD approach, wtd is computed as a function of vol and a water table factor (wt_fctr), which converts vol into wtd. The constant wt_fctr is currently a calibration parameter However, at the watershed scale where there are many fields (hydrologic response units, HRUs), it is difficult if not impossible to determine an optimum wi_fctr value for each HRU through the calibration process. The objectives of this study were to: (1) revise the modified DRAINMOD wtd algorithm in SWAT so that wt_fctr is automatically computed by the model as a function of soil physical properties in order to eliminate determination of wt_fctr through the calibration process, and (2) evaluate the revised modified DRAINMOD wtd algorithm within SWAT using measured wtd data for three observation wells located in forest fields within the Muscatatuck River basin in southeast Indiana. On average, the calibrated wt_fctr yielded daily NSE values of 0.64 and 0.41, PBIAS values of -.13% and -4%, and RMSE values of 0.41 m and 0.59 m during the calibration and validation periods, respectively, for the three observation wells. The automatically computed variable wt_fctr yielded daily NSE values of 0.66 and 0.58, PBIAS values of 4% and 10%, and RMSE values of 0.40 m and 0.50 m during the calibration and validation periods, respectively, for the same observation wells. Based on these model performance results, there were no significant differences between the wtd simulated using the manually calibrated constant and the automatically computed variable wt_fctr values. The automatically computed variable wt_fctr will enable the revised modified DRAINMOD shallow wtd algorithm to be used at the watershed scale.

TI ENHANCEMENT OF SWAT-REMM TO SIMULATE REDUCTION OF TOTAL NITROGEN WITH

AB In recent years, riparian buffers have become known as one of the most effective best management practices for nonpoint-source pollution. However, establishment of riparian buffer systems with respect to plant species and their position in the buffer zone has not been investigated due to lack of efficient evaluation methods for the analysis of water quality improvement with established riparian buffers. To solve this problem, the SWAT-REMM prototype version was developed by researchers in Canada. In the SWAT-REMM prototype version, many riparian-related input parameters are not directly read from the local input data. Thus, a SWAT-REMM enhancement was developed by improving three major limitations of the prototype version of SWAT-REMM: (1) riparian buffers at designated reaches in the watersheds, (2) riparian buffers using local soil properties at the riparian buffer zone along reaches, and (3) multiple weather stations in a larger-scale watershed. The enhanced SWAT-REMM version was applied to the Bonggok watershed in Korea. This study investigated riparian buffers with different widths (10 m, 5 m, and 1 m) along the slope. Total nitrogen reduction ranged from 14.8% to 54.0% in each catchment for 10 m widths. Total nitrogen reduction ranged from 6.9% to 31.6% in each catchment for 1 m widths. The reduction efficiency was not simply proportional to the width of buffers. This study evaluated the enhanced SWAT-REMM simulation of water quality improvement. Based on this research, the enhanced SWAT-REMM can be used to evaluate water quality improvement by riparian buffers at various watersheds worldwide using local data. In particular, simulation of riparian buffers at user-designated reaches in a watershed enables simulation of riparian buffers in watersheds experiencing frequent flooding where no riparian buffers can be established. It is expected that the enhanced SWAT-REMM can be used to determine economical and environmentally optimum riparian buffer scenarios.

AB Chickpeas and lentils are two important legumes grown in the U.S. that need phytosanitary treatments before export to several countries, but it is difficult to artificially infest them with live cowpea weevil for radio frequency (RF) treatment validation. To evaluate the more readily infested black-eyed peas and mung beans as surrogates for chickpeas and lentils, the thermal and dielectric properties of black-eyed peas and mung beans at selected moisture contents were measured and compared with those of chickpeas and lentils. Temperature differences between black-eyed pea and chickpea or between mung bean and lentil were determined in a pilot-scale 27 MHz RF unit. The results showed that the dielectric constant and loss factor of black-eyed pea and mung bean increased with increasing moisture content and temperature, which was in good agreement with the trends observed in chickpea and lentil. After 6 min of RF heating, temperatures in black-eyed pea (moisture content of 8.8% w.b.) were 6 degrees C higher than those in chickpea (moisture content of 7.0% w.b.), while after 10 min of RF heating mung bean temperatures (moisture content of 10.2% w.b.) were 4 degrees C higher than lentil temperatures (moisture content of 7.1% w.b.) under the same treatment conditions. By reducing the moisture contents in black-eyed pea and mung bean to 2.6% and 3.7% w.b., respectively, their final temperatures were about 3.5 degrees C and 3.7 degrees C lower than those of chickpea and lentil. This would result in conservative insect mortality results when using black-eyed pea and mung bean as surrogate hosts for validation of pest control treatments in chickpea and lentil.

AB Feeding behavior contains valuable information that can be used for various needs, including managing livestock, identifying animals that are sick, and determining genetic differences within a herd. Feeding behavior initially was recorded only in individual or small group pens. Currently, there are commercially available systems that determine feeding behavior and feed intake; however, these systems limit access to the feeding stations, thus changing feeding behavior. A system was developed using radio-frequency identification (RFID) technology and a series of multiplexers to determine individual animal feeding behavior in an industry-type feeding system. This system has been applied to both feedlot cattle and grow-finish swine. Validation of the cattle system determined that it was in agreement with independent video monitoring equipment 98.3% of the time, and the swine system was in agreement 98.7% of the time. Both systems have proven to be rugged and reliable in livestock industry settings.

AB Accurate measurement of gas production from biological processes is important in many laboratory experiments. A gas flow rate measurement system, consisting of an embedded controller operating three gas meters, was developed to measure volumetric flows between 0 and 9 nil, min(-1) (1 atm, 273 K). The gas meter system builds on earlier pressure-based designs by adding a reference chamber to avoid errors associated with atmospheric pressure fluctuations. The controller has a keypad and LCD that guides users through operation, logs data, and can be connected to a computer for data retrieval using a custom graphical user interface. Each of the three gas meters was calibrated using a bubble meter as the standard. The error in gas flow rates measured by the calibrated gas meter is expected to be within 0.17 mL min(-1) 95% of the time. The gas metering system was used to measure biogas production from batch anaerobic reactors that were operated for biohydrogen production using non-fat milk as the substrate. The results show that the gas meter can be used to collect accurate and high-resolution gas flow data from laboratory bioreactors.

AB Field evaluations of on-farm surface irrigation systems provide information to assess and improve irrigation system performance, design new irrigation systems, and compare irrigation methods and practices. Among the most important field data needed for evaluating on-farm surface irrigation systems are accurate measurements of the water advance and recession times at multiple stations along the irrigation length of run. However, manual data collection is labor and time intensive and is often inaccurate due to lack of visibility of surface water at remote locations in large fields. To overcome these obstacles, an inexpensive field probe was developed to measure and record the water advance and recession times. The objectives of this article are to present information on the design, construction, and validation of the probe. The battery-operated probe consists of a programmable microcontroller chip, designed to be a real-time clock and calendar, a 16 character x 1 line LCD display module writer, and fiber optics sensors at the probe base to detect the presence and absence of water. Component cost to construct the probe is about $50 US. Field evaluation of probe performance was conducted in irrigated-furrows utilizing 40 and 28 probes in two separate field tests. Mean probe times for advance were 1.1 min longer than mean observed advance times for both tests and mean probe times for recession were 1.0 min longer, and 2.6 min shorter than mean observed recession for the first and second test, respectively. The mean differences were significantly different from zero according to paired T-tests, indicating a general bias towards slightly longer probe times than observed. However, mean absolute errors for probe times were less than 8% for advance and less than 3% for recession, suggesting that the probes will provide acceptable advance and recession information for most surface-irrigation evaluation applications. The Nash-Sutcliffe model efficiency coefficients for assessing goodness of fit were above 0.94 for advance and above 0.57 for recession, which also indicated that probe times achieved good agreement with observed times.

TI DETERMINING THE OPTIMUM TIMING FOR THE FINAL FURROW IRRIGATION ON
MID-SOUTH COTTON
SO APPLIED ENGINEERING IN AGRICULTURE
LA English

AB A common question from cotton farmers in the U.S. Mid-South is when to stop irrigating the crop. U.S. Cotton growers are adopting COTMAN to monitor crop development and aid in making end-of-season decisions concerning the optimal dates for safe termination of insect control and application of defoliants. The objective of this research was to investigate a similar crop-based recommendation for timing the final irrigation on cotton. Data sets from 28 Mid-South cotton fields conducting irrigation termination studies during the 2000 through 2007 growing seasons were analyzed. Day of year, days after planting, and growing degree days after planting, all until the last irrigation, did not provide a strong enough relationship with yield to guide late-season irrigation decisions. Days after nodes above white flower (NAWF)=5 (DA5) and growing degree days after NAWF=5 (GDDA5) of the last irrigation in the northern portion of the Mid-South did provide a yield impact estimate suitable for developing recommendations, but a relationship for fields south of 34 W latitude could not be established. Based on the resulting equations for a cotton price of $1.15 kg(-1) of lint, an irrigation applied after 18 days or 192 GDD, 15.6 degrees C base, after NAWF=5 would not be expected to produce enough additional yield to be profitable. The derived equations can also be used to determine the GDDA5 and DA5 of the last profitable irrigation for a known lint price and diesel cost, allowing the producer to react to his or her individual situation. Six of the fields were harvested twice and a later crop (i.e., a lower % first harvest) was associated with later irrigation, though the differences were not always significant. When fiber quality was measured, significant differences were seldom observed and no consistent trend relating to final irrigation was observed. However, because of the price discounts associated with low or high micronaire and the relationship between micronaire and crop maturity, additional research is needed to refine the fiber-quality relationship for the Mid-South.

ID COLLECTION EFFICIENCY
AB Zero-tension pan lysimeters and passive capillary fiberglass wick lysimeters are useful in determining water quality and volumetric aspects of subsurface water flow. A crucial aspect of installing pan and wick lysimeters beneath undisturbed soil is preventing cave-in of the tunnels in the soil that house the lysimeters. Equipment and a method were developed for installing zero-tension pan lysimeters and wick lysimeters in field plots, and this new method provides substantial structural strength of the tunnels. The dimensions of the upper horizontal surface of the pan lysimeters that were used were 0.280 x 0.430 m, and those of the wick lysimeters were 0.300 x 0.300 m, but the equipment can be modified to accommodate other lysimeter dimensions. The main equipment components are steel boxes which are pushed horizontally from a pit, into soil beneath the field plot, and a guiding frame that pushes the boxes using a hydraulic cylinder powered by a tractor hydraulic system. Following installation of each pair of steel boxes in soil, the soil from within the boxes was excavated, the upper lid of the lysimeter box was removed, and a lysimeter was placed within the box with the upper surface of the lysimeter directly contacting the soil. The equipment and method were used in the sandy loam soil of tall fescue (Fescue arundinacea Schreb.) pasture plots and the equipment and method worked well. The method also helps assure accurate lysimeter depth and levelness. The lysimeters were installed at a depth of 0.500 m beneath the soil surface. Costs and labor requirements for developing the equipment and using the method are presented. There was no evidence that the installation method altered the soil bulk density or the water flow paths above the lysimeters.

AB Tillage produces a more favorable soil physical environment for seed germination and plant growth. A 2-year study was carried out to compare effects of conventional (CT) and strip (ST) tillage practices on soil bulk density (rho(b)), water content (theta(w)), final infiltration rate (I-r) and saturated hydraulic conductivity (K-s) for a Lihen sandy loam where sugarbeet (Beta vulgaris L.) was grown during the 2007 and 2008 growing seasons. Under each tillage system, we measured rho(b) and theta(w) using soil cores collected from the center of crop rows in all plots at soil surface (0 to 10 cm) and 10-to 30-cm depths. At both depths under each tillage system, we measured in-situ I-r using a pressure ring infiltrometer (PI) and in-situ K-s using a constant head well permeameter (CHWP). Although we noted a significant difference in rho(b) between CT and ST plots at 10- to 30-cm depth in 2007, soil theta(w) did not differ significantly between CT and ST plots in 2007. In 2008, soil rho(b) and theta(w) did not differ significantly between CT and ST plots at both depths. The log-transformed I-r was affected by tillage practice at P <= 0.1 in 2007 but was not significantly affected in 2008. The effects of tillage on log-transformed K-s were significant at P <= 0.05 in 2007 and P <= 0.1 in 2008. Soil K-s values were 68% and 56% greater for ST than for CT in 2007 and 2008, respectively. We concluded that ST reduced soil compaction in the row, consequently increased total porosity, reduced rho(b), and thereby increased I-r and K-s in the soil.

AB The objective of the study was to explore the use of the Fitzpatrick Comminuting Machine (FitzMill (R)) to remove the hull from hulled barley while keeping the barley kernel intact, thereby avoiding starch loss. Traditionally, this mill is used to grind material, but we have discovered that it can precisely shear the hull from the kernels using the sharp end of the blades. Different residence times in the mill were compared, and chemical analysis of hull and de-hulled kernel fractions, as well as rates of progressive hull removal, were studied to determine optimal settings. While whole kernels had only about 60% starch content, de-hulled barley kernel fractions had starch contents of over 71%, which are comparable to high-starch grains, such as corn, which are more efficient for fuel ethanol production. Furthermore, corresponding hull fractions contained less than 6% starch which translates to less than 1.5% starch loss from the original kernel. De-hulling will make a significant improvement to the barley's value as a feedstock for fuel ethanol production, increasing the starch content by 11 percentage points, and simultaneously decreasing non-fermentable fractions by a similar level. With a method to fractionate hulled barley into high-starch fractions (de-hulled kernels) and fiber rich hulls, hulled barley becomes a more desirable feedstock for fuel ethanol production. Also, since hulls would be removed prior to ethanol production they would be available for conversion into other valuable coproducts.

AB A real-time, non-contact stem detection system was developed for crop plant location sensing in automatic weed control in transplanted tomato fields. A tractor-mounted, portable x-ray source projected an x-ray beam perpendicular to the crop row and parallel to the soil surface. In operation, the plant's main stern absorbs x-ray energy, decreasing the voltage output (signal) from the detector, allowing robust main stem detection even in the case where the main stem is occluded by weed or crop foliage. This signal was used to automatically control the operation of a pair of in-row mechanical weed knives. Minimizing the source to detector distance allowed for differences in signal strength between stems and background between 180 and 300 mV (60% to 100% drop in signal strength) at low x-ray energy and current levels (25 keV, 7 mA), which is a significant advantage for safety reasons. Background noise levels were +/-30 mV, corresponding to a range of 10% to 16.7% of signal strength. The detector utilized a linear array of photodiodes aligned perpendicular to the soil surface. This configuration helped differentiate branches, which are angled and block only some of the photodiodes, from the main stem which has a similar vertical alignment as the array and hence blocks most or all photodiodes. A field trial was conducted at the standard time of first cultivation in a 17.5-m section of row in an organic transplanted tomato field, containing 43 tomato transplants. At a travel speed of 1.6 km/h, the detection system correctly identified 90.7% of main stems of the tomato plants. Four tomato plants (9.3%) were not detected because they had fallen over and passed below the detector There were no false positive detections.

DE NIR spectroscopy; Cotton fiber strength; HVI strength; Stelometer

AB Cotton fiber strength is one of important quality characteristic that is related with the manufacturing of quality goods for consumers. Currently, two types of instrumentals have been utilized to determine the cotton fiber strength in cotton industry, namely, automation oriented HVI and laboratory-based Stelometer device. Each of these instruments has its unique advantages, and apparently, correlation between the two strength readings was relatively low Meanwhile, HVI strength-based near infrared (NIR) model was observed to lack the sufficient efficiency for practical application. In this study, both HVI and Stelometer strength readings were corrected by respective micronaire values in both quotient (strength/micronaire) and product (strength*micronaire) forms, then the effect of modified HVI strength indices on NIR model performance were examined through partial least squares (PLS) regression. Two modified strength indices were observed to have a much improved relationship, and also corrected HVI strength indices were found to have a better correlation than raw HVI strength index with NIR spectra. Especially, the use of quotient form resulted in a more improved model performance than that of product one, suggesting the potential of NIR technique in the prediction of fiber strength/micronaire index for quality control application. On the basis of small sample numbers from two NIR instruments, this study indicates a "proof-of-concept" and a promising NIR model implementation.

AB The wide variety of animal manure slurry storage structures and the spatially heterogeneous nature of manure within the storage structure present a difficult challenge to researchers studying the composition and activities within manure storage systems. The objective of this study was to design and construct a manure sampling system that could be used to sample manure at various depths greater than 7.6 m (25 ft) from a variety of swine manure storage systems, including deep pit, lagoon systems, and above ground manure slurry storage tanks. Two slurry sampler systems were devised that could be lowered to a variety of depths within the manure slurry and then opened and closed remotely in order to collect a sample from a specific depth with minimal contamination from manure slurry from shallower or deeper depths. Over more than a year, these two samplers were repeatedly field tested at four animal production sites. These two designs proved to be low cost, robust, and possessed a combination of several features (easily transportable, large sample orifice, minimal sample contamination, ample volume collection, and variable depth collection) that were not available in commercially-available wastewater collection systems designed for sample collection at municipal wastewater plants.

AB Tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), nymphs and adults were collected from tall goldenrod, Solidago canadensis L. var. scabra Torr. and Gray, in Washington County, MS, during October and November 2008 and 2009. Adults were dissected to determine their reproductive status in order to evaluate host suitability of tall goldenrod relative to production of overwintering tarnished plant bug adults. Mean numbers of nymphs each week on tall goldenrod were used to evaluate the plant as a reproductive host. Results showed that tall goldenrod served as a reproductive host from flowering until a killing freeze occurred (5 weeks in 2008 and 10 weeks in 2009) with mean numbers as great as 58.7 +/- 25.7 nymphs per 25-sweep sample. Most tarnished plant bug adults utilizing tall goldenrod as a host were in diapause for overwintering by the end of the second week in October of both years. A laboratory test showed tarnished plant bug adults could utilize mature tall goldenrod seeds as food. A field test was used to compare host suitability of tall goldenrod and blooming henbit, Lamium amplexicaule L., with regard to the timing of diapause termination in tarnished plant bug adults. Adults were collected on the same dates in December and January from tall goldenrod and from blooming henbit and dissected to determine reproductive status. Results showed the possible feeding of adults on tall goldenrod seeds had little effect on diapause termination as compared to adults that fed on henbit and began terminating diapause about 3 weeks earlier. This information will be useful in developing controls to reduce the size of the overwintering generation of tarnished plant bug.

AB The southern green stink bug, Nezara viridula (L.), utilizes stylets while feeding to pierce the wall of a boll of cotton, Gossypium hirsutum L., and can inoculate disease-causing pathogens into developing green bolls. Detection of diseased bolls is difficult because the surface of the carpel wall frequently lacks apparent macroscopic evidence of insect feeding regardless of infection; blisters on the interior surface of the carpel wall are commonly masked by darkened necrotic tissue. The objectives of this study were to characterize microscopic evidence of feeding by laboratory-reared southern green stink bugs on greenhouse-grown cotton bolls and to use these findings to aid in detection of feeding evidence by piercing-sucking insects on field-collected bolls from four southeastern states. Microscopic analyses of greenhouse-reared bolls fed upon by southern green stink bug (n = 40) yielded definitive characteristics and imagery of feeding evidence. Salivary flanges on the exterior surface of the boll and blisters at the feeding site on the interior surface of the carpel wall were characteristic of feeding by southern green stink bug. Also, salivary flanges were associated with all external puncture wounds on the boll wall. These characteristics were used as the baseline to detect feeding by feral piercing-sucking pests on field-grown bolls during the 2008 and 2009 production seasons. Injury characteristics from field-grown bolls were comparable to characteristics observed in greenhouse-reared bolls after feeding by southern green stink bug. A few field-collected bolls (5%; n = 160) possessed discolored seeds and exhibited evidence of boll feeding externally but lacked blisters on the interior surface of the carpel wall, thus suggesting an incomplete breach of the interior carpel wall. Callus tissue, colloquially termed a 'wart,' on the interior surface of the boll carpel wall is typically associated with feeding by stink bugs but was not detected in bolls grown in a greenhouse and was only sporadically detected in bolls collected from the field. When present, callus tissue was always associated with an external puncture. This is the first study to unequivocally illustrate microscopic characteristics associated with feeding damage by southern green stink bug on cotton bolls. Findings are discussed in relation to evidence of feeding by insects in field-collected bolls of unknown age and history.

TI Effect of Hexaflumuron on Feeding Response and Reproduction of Bollworm,

SO SOUTHWESTERN ENTOMOLOGIST

DT Article
ID VOLATILE-BASED ATTRACTICIDE; COTTON
AB Hexaflumuron (Consult (R) 100 EC, Dow AgroSciences) is an insect growth regulator that inhibits chitin synthesis. The efficacy of hexaflumuron mixed with 2.5-M sucrose (mg(-1)) was evaluated for toxicity, proboscis extension, gestation, and reproduction of bollworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), in a laboratory. The intention was to determine whether or not hexaflumuron could be used as a toxicant in a feeding-stimulant mixture for suppression of bollworm. Newly emerged bollworm adults actively seek carbohydrates. For feral male bollworm captured in pheromone-baited traps, the lethal concentration (LC(50)) values 24 and 48 hours after exposure were 295.6 and 96.03 mg(-1), respectively. These values were significantly different. Hexaflumuron at 100 mg(-1) or more significantly depressed gustatory response of feral male and laboratory-reared male and female bollworms. There was no significant difference in proboscis-extension response between bollworms fed 1.0 and 2.5 M sucrose solutions. Percentage hatch of eggs oviposited by laboratory-reared females during 3 consecutive days was significantly less at concentrations of 5.0 mg(-1) or greater of hexaflumuron when compared with females fed 2.5-M sucrose. However, when laboratory-reared males fed hexaflumuron were compared with males fed 2.5-M sucrose solution, percentage of eggs that hatched was not significantly less. This suggests that hexaflumuron acted as an ovicide. It is posited that hexaflumuron could be a useful toxicant in a feeding-stimulant mixture for suppression of bollworm.

AB In all bioassays in the laboratory, the mortality of neonate beet armyworm, Spodoptera exigua (Hubner); cabbage looper, Trichoplusia ni (Hubner); bollworm, Helicoverpa zea (Boddie); and fall armyworm, Spodoptera frugiperda (J. E. Smith); were greater on dual-Bt (Bollgard II) varieties (average 85.4%) than on single-Bt (Bollgard) cotton (average 45.3%). Bollworm was the most susceptible to Bollgard (average mortality 68.8%), while mortality of beet armyworm was 35.2%, cabbage looper 50.4%, and fall armyworm 49.7%. Mortality of beet armyworm after feeding on Bollgard II and Wide Strike Bt traits was 74.1%, and significantly less than of cabbage looper (95.5%), bollworm. (90.4%), or fall armyworm (87.2%). Assessing the efficacy of transgenic plants under new environmental and management regimes is of prime importance to the companies that produce new or improve existing transgenic products; plant breeders who create different varieties stacked with Bt endotoxins; and farmers who grow them. For 2006-2009, we did thousands of laboratory bioassays from different Bt trait varieties of cotton. But in the process of investigations, we observed variable data with some of the same treatments and the same initial insects. These reduced accuracy of results and interpretation. Laboratory and field performance of cotton, Gossypium hirsutum L., containing endotoxins should be standardized. Only this can provide accurate and stable data for insect control with different transgenic technology. We discuss approaches and criteria for mass rearing standardized laboratory colonies of beet armyworm, fall armyworm, and bollworm, for laboratory and field evaluation of efficacy of Bt cottons.

AB Seven polymorphic microsatellite markers were used to analyze bollworm, Helicoverpa zea (Boddie), populations from various host plants in four locations in the southern United States. Linear distance between collection sites ranged from approximately 150 to 900 km. The analysis indicated low allelic range for all loci (2.286 +/- 0.488 to 2.571 +/- 0.787). Chi-square goodness-of-fit tests for deviation from Hardy-Weinberg equilibrium were not significant. Inbreeding coefficients, F(IS), were very variable among the seven loci with a bootstrap-generated overall value of -0.104 +/- 0.178 across all loci and populations. Overall population differentiation estimates, represented by F(ST), were essentially zero. In the analysis of variance of genotypes grouped into various geographical combinations, variation within individuals accounted for more than 93% of the total variation while no significant variation was detected between groups, among populations within groups, or among individuals within populations. The results indicated that extensive gene flow occurred between geographically distant bollworm populations, and the populations studied did not show any signs of differentiation based on the geographical location. Although there are no other microsatellite-based population studies for comparison, the results of the present study are congruent with the results of allozyme analyses on this species.

Microsatellite Markers in the Tobacco Budworm, Heliothis virescens
(Lepidoptera: Noctuidae)
SO SOUTHWESTERN ENTOMOLOGIST
LA English
DT Article
ID SSR MARKERS; SIMILARITY
AB Polymorphic genetic markers were identified and characterized using a partial genomic library of the tobacco budworm, Heliothis virescens (Fabricius), enriched for simple sequence repeats (SSR) and nucleotide sequences of expressed sequence tags (EST). Nucleotide sequences of 192 clones from the partial genomic library yielded 147 unique SSRs while EST evaluations identified 280 SSR-containing sequences. All anonymous SSRs and 192 EST-SSRs were evaluated to select loci that produced the best quality peaks without stutter peaks. Six anonymous markers and nine EST-derived markers were selected to evaluate a sample of 96 insects collected from Stoneville, MS. The observed number of alleles ranged from two to eight, with an average of 5.87 (SE +/- 0.53). The polymorphic information content (PIC) value averaged 0.446 (SE +/- 0.052). Significant deviations from Hardy-Weinberg expectations were detected at eight loci. We speculate that these loci are under selection in the population of tobacco budworm used in the study. No significant linkage disequilibrium was detected at any of the loci. Proportions of anonymous and EST-SSR markers validated after extensive evaluation were 4.08 and 4.68%, respectively. One anonymous SSR marker (HvMS117) and all nine EST markers were transferable to the bollworm, Helicoverpa zea (Boddie).

AB Insects in the order Hemiptera are considered the second most important group of plant pathogen vectors, after aphids as agriculture crop pests. Genomic approaches are providing new information on the genetic basis of biology, behavior, and refinement of their phylogenetic classification. Three leafhopper species, important as vectors of plant pathogenic bacteria referred to as Xylella fastidiosa (Hemiptera: Cicadellidae), were examined by comparison of the available expressed sequence tags, similar to 43,400 ESTs from three leafhopper species (Hunter datasets, NCBI). These species are vectors of the plant-pathogenic bacterium, Xylella fastidiosa (Wells et al.) the causal agent of Pierce's disease of grapevine. A tentative look at the gene expression across these three leafhopper species, the glassy-winged sharpshooter, Homalodisca vitripennis (Germar), blue-green sharpshooter, Graphocephala atropunctata (Signoret), and black-winged sharpshooter, Oncometopia nigricans (Walker), were analyzed. After comparison approximately 4,800 specific transcripts for each species were obtained, with most of these (similar to 40-48%) being identified as house-keeping. While the assembled datasets are not complete representations of all the leafhopper transcriptomes, these are predicted to be approximately one-fourth of the active genes in the genomes of these leafhoppers, based on comparative analysis of genomes of other insects in the order Hemiptera, based on an average of similar to 15k-25,000 active genes. Interest in host plant utilization led us to focus on a poorly studied set of transcripts from leafhoppers the desaturases. Delta-9 desaturase enzymes have been shown to be highly conserved throughout Eukarya (fungi, protists, plants, and animals) and specifically function to place double bonds between the adjacent carbons of specific fatty acids, playing a vital role in the internal metabolism and physiology of insects. The Delta-9 desaturase sequences of several insect species, including the three leafhopper species of this study, were used to construct a phylogenetic tree. Additional analysis highlights differences for species-specific targeting of these genes within leafhoppers. It is proposed that as new developments in genomics and strategies like RNA-interference emerge, researchers will be able to design specific and effective management tools to reduce leafhopper abundance, and/or transmission of disease by leafhoppers.

AB Psyllids, specifically Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), are economically important in the U.S. as vectors of the pathogen associated with citrus greening disease (Huanglongbing). Huanglongbing is one of the most severe diseases of citrus crops worldwide and is associated with psyllid-transmitted 'Candidatus Liberibacter asiaticus'. The microbiome of the Asian citrus psyllid was investigated; we analyzed Eubacterial 16S rDNA amplified from adults, eggs, and cell cultures. The nucleotide sequences showed significant homologies to 10 distinct types of bacteria. The four bacteria species detected in cell cultures identified two new types not previously reported to be associated with psyllids. Staphylococcus is a common enteric bacterium; these data support finding a type I strain which is similar. Another related to Methylocystis heyeri is a bacterium typically isolated from acidic environments that has been shown to utilize methane as the sole source of carbon and energy. Psyllid cell cultures are at a slightly acidic pH of similar to 6.48, with the cultures derived from a diverse set of tissues that may include enteric tissues. These associated microbes of Asian citrus psyllid provide new insights into microbial interactions and avenues for developing novel management approaches against the pathogenic bacteria associated with Huanglongbing.

AB The southern cattle tick, Rhipicephalus (Boophilus) microplus (Canestrini), is considered to be one of the most significant pests of cattle worldwide. A vector for piroplasmosis, or cattle fever, the southern cattle tick is a key target of an aggressive eradication program along the U.S.-Mexico border. Endemic to subtropical and tropical regions, southern cattle ticks are limited in range by climate and temperature. Neither adults nor larvae of southern cattle tick survive more than a few days of subfreezing temperatures. Nonetheless, in a separate study of fecundity of southern cattle tick in different field conditions, where bagged samples of egg masses were allowed to hatch in the field then placed in a freezer in order to estimate egg hatch, a single southern cattle tick larva was found alive following exposure to room temperature after 20 days of cold-exposure. Although quite anomalous, this report of this outlying observation suggests the possibility that southern cattle tick can survive extremely cold temperatures for long durations.

LOCATION; MODELS; GROWTH; EXTERNALITIES; PATTERNS; DESIGN
AB Urban growth compromises open space and ecosystem functions. To mitigate the negative effects, some agencies use reserve selection models to identify conservation sites for purchase or retention. Existing models assume that conservation has no impact on nearby land prices. We propose a new integer program that relaxes this assumption via adaptive cost coefficients. Our model accounts for the two key land price feedbacks that arise in markets where conservation competes with development: the amenity premium and price increases driven by shifts in market equilibriums. We illustrate the mechanics of the proposed model in a real land retention context. The results suggest that in competitive land markets, the optimal conservation strategy during the initial phase of the retention effort might be to use available dollars to buy fewer parcels with smaller total area that are under high risk of development. We show that failure to capture the land-price feedbacks can lead to significant losses in biological conservation. The present study is the first to create a reserve selection model that captures the economic theory of competitive land markets in a dynamic framework, produces tangible, parcel-level conservation recommendations, and works on problems with thousands of potential site selection decisions and several planning periods.

DE Caribbean; Taino; wood; sculpture; tenth-sixteenth centuries AD
AB Five wooden sculptures from the pre-contact Caribbean, long held in museum collections, are here dated and given a context for the first time. The examples studied were made from dense Guaiacum wood, carved, polished and inlaid with shell fastened with resin. Dating the heartwood, sapwood and resins takes key examples of 'Classic' Taino art back to the tenth century AD, and suggests that some objects were treasured and refurbished over centuries. The authors discuss the symbolic properties of the wood and the long-lived biographies of some iconic sculptures.

ID PYRALIDAE
AB The homology and terminology of the sclerotized structures, specifically the uncus and gnathos, formed by the fused segments caudal to the ninth abdominal segment in males of Lepidoptera, specifically in the Pyraloidea, have been confused in the literature. Based on comparative morphology of sclerotized structures and musculature, the uncus, scaphium, gnathos, and subscaphium are defined and described for stabilization in future systematic studies. Muscles IX-X (ex) and IX-X (int) are associated with these sclerotized structures and attached to the tegumen anteriorly. They are present in most of the species examined and are consistently topologically constrained in their origins and insertions; no differences were observed at the familial level. Muscle IX-X (int) is lacking in Pyralinae (Pyralidae) and this condition is hypothesized to be derived independently and an autapomorphy for this subfamily. The unique subteguminal processes of the Schoenobiinae are structures independent of the gnathos contrary to previous thought, and are instead associated with the valvae. Published by Elsevier Ltd.

AB Spectral fingerprints of samples of three Panax species (P. quinquefolius L., P. ginseng, and P. notoginseng) were acquired using UV, near-infrared (NIR), and MS. With principal component analysis, all three methods allowed visual discrimination among the three species. All three methods were able to discriminate between white and red ginseng, and showed distinctive subgroupings of red ginseng related to root quality (age/size). Analysis of variance was used to evaluate the relative variance arising from the species, run, and analytical uncertainty, and was used to identify the most information-rich portions of the spectrum for NIR and UV. Accurate classification of the three species was obtained by using partial least squares-discriminant analysis and a fuzzy rule-building expert system. Relatively poor accuracy was obtained using soft independent modeling of class analogy when a single component was used.

AB For a century, US Forest Service experimental forests and ranges (EFRs) have been a resource for scientists conducting long-term research relating to forestry and range management. Social science research has been limited, despite the history of occupation and current use of these sites for activities ranging from resource extraction and recreation to public education. This article encourages researchers to take advantage of the rich, though largely untapped, potential EFRs offer for social science by describing their many human dimensions and providing an overview of potential research topics. These topics include human uses, economics, historical studies, population and land-use change, human values, and interdisciplinary social-ecological studies. Lack of awareness among social scientists, limited budgets and networking, and the predominance of biophysical scientists who administer and conduct research at EFRs appear to be inhibiting the development of social science research there. We suggest ways of overcoming these barriers.

AB In an era of declining timber harvests on federal lands, the US Forest Service has sought to better describe the public benefits associated with the nation's continued investment in managing the national forests. We considered how national forests contribute to public health by providing significant outdoor recreation opportunities. Physical inactivity has become a persistent national concern owing to its association with chronic diseases, obesity, and other public health concerns. We estimated the net energy expenditure (in calories) for a range of outdoor recreation activities engaged in by visitors to national forests. We conclude that national forest contributions to physical activity among the American public likely are significant and could be enhanced with continued and targeted investments in recreation infrastructure and public outreach.

AB The purpose of this study was to examine the association of 100% orange juice (OJ) consumption by children 2 to 18 years of age (n = 7250) participating in the 2003 to 2006 National Health and Nutrition Examination Survey with intakes of select nutrients, MyPyramid food groups, diet quality-measured by the Healthy Eating Index-2005, weight status, and associated risk factors. The National Cancer Institute method was used to estimate the usual intake of 100% OJ consumption, selected nutrients, and MyPyramid food groups. Percentages of the population below the Estimated Average Requirement were determined. Covariate adjusted logistic regression was used to determine if consumers had a lower odds ratio of being overweight or obese. Usual per capita intake of 100% OJ was 1.7 oz/d. Among consumers, the usual intake of 100% OJ for children (n = 2183; 26.2% of population) was 10.2 oz/d. Consumers had higher (P < .05) energy intakes than nonconsumers (9148 +/- 113 vs 8625 +/- 473 Id). However, there were no differences in weight or body mass index in consumers and nonconsumers, and there was no significant difference in the risk of being overweight or obese between consumers and nonconsumers (odds ratio, 0.86; 95% confidence interval, 0.70-1.05). Compared with nonconsumers, consumers had a higher (P < .01) percentage (% +/- SE) of the population meeting the Estimated Average Requirement for vitamin A (19.6 +/- 2.0 vs 30.2 +/- 1.4), vitamin C (0.0 +/- 0.0 vs 29.2 +/- 1.2), folate (1.3 +/- 0.3 vs 5.1 +/- 0.6), and magnesium (25.5 +/- 2.0 vs 39.0 +/- 11). The Healthy Eating Index-2005 was significantly (P < .01) higher in consumers (52.4 +/- 0.4 vs 48.5 +/- 0.3). Consumers also had higher intakes of total fruit, fruit juice, and whole fruit. Moderate consumption of 100% OJ should be encouraged in children as a component of a healthy diet. (C) 2011 Elsevier Inc. All rights reserved.

AB With the advent of high-throughput sequencing, the availability of genomic sequence for comparative genomics is increasing exponentially. Numerous completed plant genome sequences enable characterization of patterns of the retention and evolution of genes within gene families due to multiple polyploidy events, gene loss and fractionation, and differential evolutionary pressures over time and across different gene families. In this report, we trace the changes that have occurred in 12 surviving homoeologous genomic regions from three rounds of polyploidy that contributed to the current Glycine max genome: a genome triplication before the origin of the rosids (similar to 130 to 240 million years ago), a genome duplication early in the legumes (similar to 58 million years ago), and a duplication in the Glycine lineage (similar to 13 million years ago). Patterns of gene retention following the genome triplication event generally support predictions of the Gene Balance Hypothesis. Finally, we find that genes in networks with a high level of connectivity are more strongly conserved than those with low connectivity and that the enrichment of these highly connected genes in the 12 highly conserved homoeologous segments may in part explain their retention over more than 100 million years and repeated polyploidy events.

AB Although consumption of mandarins has grown steadily in the United States, mandarin cultivars being produced and consumed have been changing. The goal of this research was to identify factors that impact consumer choice of mandarins. In this analysis, consumers were presented with multiple mandarins for taste tests and then asked to identify their willingness to purchase the products. The results from our study suggest that sweetness, shape, acidity, and flavor are the most important factors related to their willingness to try a mandarin, and factors such as seeds, size of fruit, color, and overall appearance were less important.

AB The gypsy moth, Lymantria dispar (L.), is a polyphagous defoliator introduced to Medford, Massachusetts in 1869. It has spread to over 860,000 km 2 in North America, but this still only represents 1/4 of its susceptible host range in the United States. To delay defoliation in the remaining susceptible host range, the government maintains a barrier zone and a quarantine, reflecting a presumption that anthropogenic factors are important in the spread of gypsy moth. We develop a model framework that relates these factors along with biophysical characteristics to a county's susceptibility to gypsy moth invasion. We then compile a dataset for counties within 200 km of the infested area and use trap catch data from 1999 to 2007 to estimate the probability of gypsy moth presence. As expected, gypsy moth is more likely to be found close to the population front and to traps that recorded moths in the previous year. However, when controlling for these factors, our most robust finding is that the use of wood for home heating and energy is consistently positively correlated with the presence of gypsy moth. In contrast, the movement of wood products by industry, which is actively regulated by state and federal governments, is rarely correlated with the presence of gypsy moth. This is consistent with effective regulation of the movement of goods by industry, but not by the public. Our findings provide empirical support for the importance and challenge of firewood as a vector for non-native forest insects.

AB The wool carder bee, Anthidium manicatum, is the most widely distributed unmanaged bee in the world. It was unintentionally introduced to North America in the late 1960s from Europe, and subsequently, into South America, New Zealand and the Canary Islands. We provide information on the local distribution, seasonal abundance and sex ratio of A. manicatum from samples collected in an intensive two-year survey across Utah, USA. Anthidium manicatum was detected in 10 of the 29 Utah counties, largely in urban and suburban settings. Combining presence-only and MaxEnt background data from literature, museum databases and new records from Utah, we constructed three species distribution models to examine the potential distribution of A. manicatum in its native Eurasian range as well as invaded ranges of North and South America. The A. manicatum model based on locality and background data from the species' native range predicted 50% of the invasive records associated with high habitat suitability (HS >= 0.90). The invasive North American model predicted a much broader distribution of A. manicatum (214% increase); whereas, the South American model predicted a narrower distribution (88% decrease). The poor predictive power of the latter model in estimating suitable habitats in the invasive South American range of A. manicatum suggests that the bee may still be limited by the bioclimatic constraints associated with a novel environment. Estimates of niche similarity (D) between the native and invasive models find that the North America bioclimatic niche is more similar to the bioclimatic niche of the native model (D = 0.78), whereas the bioclimatic niche of the South America invasion is relatively dissimilar (D = 0.69). We discuss the naturalization of A. manicatum in North America, possibly through punctuated dispersal, the probability of suitable habitats across the globe and the synanthropy exhibited by this invasive species.

AB Corn as a food that is heated and cooled to allow starch retrogradation has higher levels of resistant starch (RS). Increasing the amount of RS can make corn an even healthier food and may be accomplished by breeding and selection, especially by using exotic germplasm. Sixty breeding lines of introgressed exotic germplasm backgrounds, selected for high yield, were grown in three tropical and temperate locations and analyzed for starch thermal characteristics and RS levels. Although actual values for all starch characteristics were within normal levels, most characteristics had significant genotypic effects, and all had significant location effects. Thermal properties of retrograded starch were more influenced by the environment than the thermal properties of raw starch, making retrograded starch traits more heritable than raw starch traits. This suggests that a breeding strategy based on retrograded starch traits will have a better chance of success than a breeding strategy based on raw starch traits. A significant genotype effect for RS levels indicates that genotypic selection to raise the level of RS and increase the healthful aspects of corn food should be successful. Significant location effects indicate that breeders using winter nurseries to accelerate their breeding progress need to be careful when making selections using RS data collected on seed grown in the tropics. A small but highly significant correlation between RS and some thermal characteristics, especially percentage of retrogradation, indicates that we may be able to select promising genotypes for RS selection based on our extensive database of thermal characteristics collected on a wide number of diverse corn lines.

AB Arabinoxylans (AX) are the main nonstarch polysaccharides found in wheat flour. Structural changes of AX in refrigerated dough are linked to deleterious effects on refrigerated dough quality during storage. The purpose of this research was to evaluate the effect of cultivar and growing environment on dough syruping during refrigerated storage in relation to apparent xylanase activity and AX chemistry in hard red spring (HRS) wheat. Eight HRS cultivars that were grown at six locations over two years in North Dakota were evaluated for dough syruping during 15 days of refrigerated storage. When compared with genotypic effect, growing environment had a greater impact on apparent xylanase activity and dough syruping; they were found to have significant associations by log-linear regression analysis. Specifically, wheat samples produced in a dry environment had lower apparent xylanase activity and degree of dough syruping than those from a wet environment. Some HRS cultivars were identified to be consistently lower in apparent xylanase activity and dough syruping across all growing environments, indicating that those cultivars had more stability over growing environment than other cultivars. These results indicate that certain cultivars that are grown in relatively dry environments in North Dakota are more suitable for use in refrigerated dough formulations.

AB Whole-grain wheat flour is used in baking to increase fiber content and to provide vitamins from the bran layers of the kernel. We surveyed whole-grain soft flour samples from North America to determine the nutritional profile using recently revised fiber quantification protocols, Codex 2009.1. Standard compositional and vitamin analyses were also included in the survey. Three separate studies were included in the survey: sampling of commercial whole-grain soft wheat flour, a controlled study of two cultivars across three years and two locations, and a regional study of soft white and soft red grain from commercial grain production. The Codex method for fiber measurement estimated total fiber concentration in the commercial sampling at 15.1 g/100 g, dry weight basis (dwb). In the controlled research trial, the largest source of variation in total fiber concentration was attributed to year effects, followed by genotype effects. For the two locations used in this study, location effects on fiber concentration were significant but an order of magnitude less important than the year and genotype effects. The third study of regional variation within North America found limited variation for total fiber, with the resistant oligosaccharide fraction having the greatest variation in concentration. When all three studies were combined into a meta-analysis, the average total fiber concentration was 14.8 g/100 g dwb. In the meta-analysis, concentrations of folate, thiamin, riboflavin, niacin, and pyridoxine were lower than in previous summary reports. Vitamin E and pantothenic acid were the exceptions, with concentrations that were nearly identical to previous standard reports. Several other recent studies also point to current cultivars and production systems as producing lower concentrations of the essential vitamins than previously reported. The results suggest that vitamin concentrations in diets of populations using grain-based diets from modern cereal-production systems may require review to determine if previous assumptions of vitamin consumption are accurate.

AB Exposure of wheat flour to ethanol solutions followed by slow drying of the ethanol in situ alters the subsequent transformation of the flour into dough. Several types of wheat flour were exposed to small amounts of ethanol solutions so as to be "wetted" but without the appearance of a separate liquid phase. The wet sample was then dried in air. Dough was formed from the treated flour, and its rheological parameters were assessed, including time to peak strength (mixograph and farinograph) and gluten index (glutomatic). Untreated and treated flour and the dough prepared therefrom were assayed using ID SDS-PAGE (reducing and unreducing conditions), capillary zone electrophoresis (CZE) applied to 70% leachates with and without sonication, and differential scanning calorimetry. Both gluten index and time to peak increased as a result of the treatment, and the increase was greater for flour or enriched vital gluten with an initially low gluten index than for flour with a relatively high initial index. Endosperm fragmentation following milling of the treated flour was improved by the treatment. Thermal transitions were at lower temperatures following treatment, indicating less structural order and reduced thermal stability. No compositional differences were evident when studied with robust analytical methods. CZE of leached samples (no sonication) revealed lower amounts of accessible or detected proteins following treatment. Conformational changes and new secondary interactions, therefore, appear to cause the effect.

AB Commercial wheat (Triticum aestivum em. The 11) flour milling produces flour streams that differ in water absorption levels because of variability in protein concentration, starch damaged by milling, and nonstarch polysaccharides. This study characterized the distribution of water-extractable (WE) nonstarch polysaccharides (NSP) in long-flow pilot-milling streams of soft wheat to model flour quality and genetic differences among cultivars. Existing reports of millstream analysis focus on hard wheat, which breaks and reduces differently from soft wheat. Seven soft winter wheat genotypes were milled on a pilot-scale mill that yields three bleak flour streams, five reduction streams, and two resifted streams. Protein concentration increased linearly through the break streams. WENSP concentration was low and similar in the first two break streams, which are the largest break streams. Flour recovery decreased exponentially through the reduction streams; flour ash and water-extractable glucose and galactose polymers increased exponentially through the reduction streams. Protein concentration and WE xylan concentration increased linearly through the reduction streams. The ratio of arabinose to xylose in WE arabinoxylan (WEAX) decreased through the reduction streams, and response varied among the genotypes. Flour ash was not predictive of stream composition among genotypes, although within genotypes, ash and other flour components were correlated when measured across streams. The second reduction flour stream was the largest contributor to straight-grade flour WEAX because of both the size of the stream and the concentration of WEAX in the stream.

AB During experimental Eimeria infections in chickens, facilities are often contaminated by fecal oocysts known to be highly resistant to both chemical and enzymatic treatments. Thus, studies using experimental Eimeria infections have been limited due to the difficulty of complete elimination of residual oocysts from both cages and facilities. To overcome this limitation, simple, inexpensive, and disposable cages were constructed from cardboard boxes and tested during experimental Eimeria maxima infections. The cages were used in animal rooms with only a 1.7% evidence of coccidia contamination between adjacent cages. No significant differences in fecal oocyst output and body weight gain were noted between animals housed in disposable cages and animals housed in wire control cages. This cage design is a useful means for preventing oocyst contamination during experimental conditions, suggesting that this disposable cage design could be used for other avian infectious disease studies.

AB Potato virus Y (PVY) strains were originally defined by interactions with different resistance genes in standard potato cultivars. Five distinct strain groups are defined that cause local or systemic hypersensitive responses (HRs) in genetic background with a corresponding N gene: PVYO, PVYN, PVYC, PVYZ, and PVYE. The nucleotide sequences of multiple isolates of PVYO and PVYN differ from each other by approximate to 8% along their genomes. Additionally, complete genome sequences of multiple recombinant isolates are composed of segments of parental PVYO and PVYN sequences. Here, we report that recombinant isolate PVY-L26 induces an HR in potato 'Maris Bard' carrying the putative Nz gene, and is not recognized by two other resistance genes, Nc and Ny(tbr). These genetic responses in potato, combined with the inability of PVY-L26 to induce vein necrosis in tobacco, clearly define it as an isolate from the PVYZ strain group and provide the first information on genome structure and sequence of PVYZ. The genome of PVY-L26 displays typical features of European NTN-type isolates with three recombinant junctions (PVYEU-NTN), and the PVY-L26 is named PVYZ-NTN. Three typical PVYNTN isolates and two PVYN isolates, all inducing vein necrosis in tobacco, were compared with PVY-L26. One PVYNTN isolate elicited HR reactions in Maris Bard, similar to PVY-L26, while two induced a severe systemic HR-like reaction quite different from the quasi-symptomless reaction induced by two PVYN isolates. 'Yukon Gold' potato from North America produced HR against several PVYNTN isolates, including PVY-L26, but only late and limited systemic necrosis against one PVYN isolate. Consequently, according to symptoms in potato indicators, both PVYZ and PVYNTN isolates appeared biologically very close and clearly distinct from PVYO and PVYN strain groups.

AB A major justification for taxonomic research is its assumed ability to predict the presence of traits in a group for which the trait has been observed in a representative subset of the group. Similarly, populations in similar environments are expected to be more alike than populations in divergent environments. Consequently, it is logical to assume that taxonomic relationships and biogeographical data have the power to predict the distribution of disease resistance phenotypes among plant species. The objective of this study was to test predictivity in a group of widely distributed wild potato species, based on hypotheses that closely related organisms (taxonomy) or organisms from similar environments (biogeography) share resistance to a simply inherited trait (Potato virus Y [PVY]). We found that wild potato species with an endosperm balance number (EBN) of 1 (a measure of cross compatibility) shared resistances to PVY more than species with different EBN values. However, a large amount of variation was found for resistance to PVY among and within species. We also found that populations from low elevations were more resistant than those from high elevations. Because PVY is vectored by aphids, we speculate that the distribution of aphids may determine the level of selection pressure for PVY resistance.

AB Citrus Huanglongbing (HLB) is one of the most destructive diseases of citrus worldwide and is threatening the survival of the Floridian citrus industry. Currently, there is no established cure for this century-old and emerging disease. As a possible control strategy for citrus HLB, therapeutic compounds were screened using a propagation test system with 'Candidatus Liberibacter asiaticus'-infected periwinkle and citrus plants. The results demonstrated that the combination of penicillin and streptomycin (PS) was effective in eliminating or suppressing the 'Ca. L. asiaticus' bacterium and provided a therapeutically effective level of control for a much longer period of time than when administering either antibiotic separately. When treated with the PS, 'Ca. L. asiaticus'infected periwinkle cuttings achieved 70% of regeneration rates versus <50% by other treatments. The 'Ca. L. asiaticus' bacterial titers in the infected periwinkle plants, as measured by quantitative real-time polymerase chain reaction, decreased significantly following root soaking or foliar spraying with PS. Application of the PS via trunk injection or root soaking also eliminated or suppressed the 'Ca. L. asiaticus' bacterium in the HLB-affected citrus plants. This may provide a useful tool for the management of citrus HLB and other Liberibacter-associated diseases.

AB Ray blight, caused by Phoma ligulicola var. inoxydabilis, is the most damaging disease of pyrethrum (Tanacetum cinerariifolium) in Australia. Data collected from 72 plots in commercial pyrethrum fields since 2001 to 2009 revealed substantial annual variations in isolation frequency of the pathogen during semidormancy of the crop in autumn and winter. Isolation frequency of the pathogen during this time and subsequent outbreaks of ray blight in spring were similar across the eight production regions where sampling was conducted, and isolation frequency of the pathogen was linearly correlated (r = 0.88; P < 0.0001) with subsequent defoliation severity when plants commenced growth in spring. Isolation frequency and defoliation severity also were correlated with the incidence of seed infested with P. ligulicola var. inoxydabilis (r = 0.71 and 0.44, respectively; P < 0.0001 in both correlations). Highly accurate risk algorithms for the occurrence of severe epidemics of ray blight were constructed using logistic regression. A model based solely on isolation frequency of the pathogen over autumn and winter correctly predicted epidemic development in 92% of fields. Another model utilizing the incidence of infested seed and rain-temperature interactions in early autumn (austral March and April) and late winter (austral June and July) had similar predictive ability (92% accuracy). Path analysis modeling was used to disentangle interrelationships among the explanatory variables used in the second logistic regression model. The analysis indicated that seedborne inoculum of P. ligulicola var. inoxydabilis contributes indirectly to ray blight defoliation severity through directly increasing overwintering frequency of the pathogen. Autumn and fall weather variables were modeled to have indirect effects on defoliation severity through increasing overwintering success of the pathogen but also direct effects on defoliation severity. Collectively, the analyses point to several critical stages in the disease cycle that can be targeted to minimize the probability of regional epidemics of ray blight in this perennial pathosystem.

AB Mexico is a center of diversity of Gossypium. As currently circumscribed, arborescent Gossypium species (subsection Erioxylum) are widely distributed in dry deciduous forests located from Sinaloa in the north of its range to Oaxaca in the south of its range. However, extensive morphological variation exists among accessions from these different geographic regions. The objective of this work was to determine whether the observed morphological variation is reflected at the molecular level. Molecular diversity and phylogenetic relationships were estimated with 210 randomly amplified polymorphic DNA fragments and 766 amplified fragment length polymorphism fragments among 33 accessions of arborescent Gossypium, including 23 of Gossypium aridum, the most widely distributed of the arborescent Mexican diploid Gossypium species. Over 90% of the fragments were polymorphic; however, each accession contained only between 32% and 46% of the total loci. Two thirds of the loci among the G. aridum accessions had allelic frequencies lower than 80%. The genetic distance between Gossypium gossypioides (subsection Selera) and species of subsection Erioxylum ranged between 0.64 and 0.84. The genetic distance between two recognized species, Gossypium lobatum and Gossypium schwendimanii, within subsection Erioxylum was 0.32. Most molecular data support the traditional classification of Gossypium species and the geographical ecotypes of the G. aridum accessions. A newly collected accession, US-72, of subsection Erioxylum was genetically distant (range, 0.42-0.54) from the other species of the subsection. Molecular data support the recognition of this taxon as a new species. The molecular diversity among accessions of G. aridum was greater than that among the species of subsection Erioxylum. The results indicate this subsection deserves additional study to establish a defensible taxonomic treatment of the various taxa and to resolve genetically distant geographical ecotypes.

AB Scrapie is a prion-associated transmissible spongiform encephalopathy (TSE) of sheep and goats, and frequently serves as a comparative model for other prion diseases, such as chronic wasting disease and bovine spongiform encephalopathy. TSEs are unique neurologic disorders that do not appear to be accompanied by robust systemic immunologic responses. mRNA data suggest that cytokines are involved in scrapie progression. In this study, brain tissue, mesenteric lymph nodes, splenic tissue and serum from ovinized mice were screened for 62 cytokine and cytokine-related proteins at pre-clinical and clinical points of infection. Expression patterns were compared to brain histology and clinical presentation. Increased cytokine expression in the brain and periphery were noted in scrapie-positive animals before histologic changes or clinical signs were evident. Of the 62 proteins examined, only IL-10 and TIMP-1 were consistently expressed at increased levels in the serum throughout infection. These cytokines could suggest future targets for biomarkers of infection and may, as well, provide insight into the biologic dynamics of prion-associated neurologic diseases. (C) 2011 Elsevier Ltd.

AB The redbay ambrosia beetle, Xyleborus glabratus Eichhoff, is an exotic wood-boring insect that vectors the mycopathogen responsible for laurel wilt, a lethal vascular disease of trees in the Lauraceae. High mortality has occurred in native Persea species in the southeastern U. S., and the vector-pathogen complex poses an imminent threat to the production of commercial avocado, P. americana, in south Florida. There is a critical need for effective attractants to detect, monitor, and control this invasive pest. This study combined field tests and laboratory bioassays to evaluate the response of female X. glabratus to host-based volatiles from wood of avocado (cultivars of West Indian, Guatemalan, and Mexican races); from wood of lychee (Litchi chinensis, a presumed non-host that is high in the sesquiterpene alpha-copaene, a putative attractant); and to commercial lures containing manuka and phoebe oils, two reported attractive baits. Volatile collections and GC-MS analyses were performed to quantify the sesquiterpene content of test substrates. In the field, traps baited with lychee wood captured more beetles than those with wood from avocado cultivars; traps baited with phoebe oil lures captured more beetles than those with manuka oil lures (the current monitoring tool). In field and laboratory tests, X. glabratus did not show a preference among avocado races in either attraction or host acceptance ( initiation of boring). In choice tests, lychee was more attractive than avocado initially, but a higher percentage of beetles bored into avocado, suggesting that lychee emits more powerful olfactory/visual cues, but that avocado contains more of the secondary cues necessary for host recognition. Emissions of alpha-copaene, beta-caryophyllene, and alpha-humulene were correlated with field captures, and lychee wood may be a source of additional semiochemicals for X. glabratus.

AB Plants damaged by insect herbivory often respond by inducing a suite of defenses that can negatively affect an insect's growth and fecundity. Ostrinia nubilalis (European corn borer, ECB) is one of the most devastating insect pests of maize, and in the current study, we examined the early biochemical changes that occur in maize stems in response to ECB herbivory and how these rapidly induced defenses influence the growth of ECB. We measured the quantities of known maize defense compounds, benzoxazinoids and the kauralexin class of diterpenoid phytoalexins. ECB herbivory resulted in decreased levels of the benzoxazinoid, 2, 4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one)-beta-D-glucopyranose (DIMBOA-Glc), and a corresponding increase in 2-(2-hydroxy-4,7-dimethoxy-1,4-benzoxazin-3-one)-beta-D-glucopyranose (HDMBOA-Glc). Total quantities of benzoxazinoids and kauralexins were increased as early as 24 h after the initiation of ECB feeding. The plant hormones, jasmonic acid (JA) and ethylene (ET), and the transcripts encoding their key biosynthetic enzymes also accumulated in response to ECB herbivory, consistent with a role in defense regulation. The combined pharmacological application of JA and the ET precursor, 1-aminocyclopropane-1-carboxylic acid to stem internode tissue likewise resulted in changes in benzoxazinoids similar to that observed with ECB damage. Despite the fact that maize actively mounts a defense response to ECB stem feeding, no differences in percent weight gain were observed between ECB larvae that fed upon non-wounded control tissues compared to tissues obtained from plants previously subjected to 24 h ECB stem herbivory. These rapid defense responses in maize stems do not appear to negatively impact ECB growth, thus suggesting that ECB have adapted to these induced biochemical changes.

AB Plant secondary chemistry is determined by both genetic and environmental factors, and while large intra-specific variation in secondary chemistry has been reported frequently, the levels of genetic variation of many secondary metabolites in forest trees in the context of potential resistance against pests have been rarely investigated. We examined the effect of tree genotype and environment/site on the variation in defensive secondary chemistry of lodgepole pine, Pinus contorta var. latifolia, against the fungus, Grosmannia clavigera (formerly known as Ophiostoma clavigerum), associated with the mountain pine beetle, Dendroctonus ponderosae. Terpenoids were analyzed in phloem samples from 887, 20-yr-old trees originating from 45 half-sibling families planted at two sites. Samples were collected both pre- and post-inoculation with G. clavigera. Significant variation in constitutive and induced terpenoid compounds was attributed to differences among families. The response to the challenge inoculation with G. clavigera was strong for some individual compounds, but primarily for monoterpenoids. Environment (site) also had a significant effect on the accumulation of some compounds, whereas for others, no significant environmental effect occurred. However, for a few compounds significant family x environment interactions were found. These results suggest that P. c. latifolia secondary chemistry is under strong genetic control, but the effects depend on the individual compounds and whether or not they are expressed constitutively or following induction.

Influenza A virus (IAV) infections are endemic in pork producing countries around the world. The emergence of the pandemic 2009 human H1N1 influenza A virus (pH1N1) raised questions about the occurrence of this virus in Brazilian swine population. During a 2009-2010 swine influenza virus research project at Embrapa Swine and Poultry (CNPSA), an outbreak of a highly transmissible H1N1 influenza A virus disease was detected in a pig herd in Santa Catarina State, Brazil. The virus caused a mild disease in growing pigs and sows without mortality. Three clinically affected piglets were euthanized. Gross lesions included mild to moderate consolidation of cranioventral areas of the lung. Microscopically, the lesions were characterized by necrotizing obliterative bronchiolitis and bronchointerstitial pneumonia. Immunohistochemistry using a monoclonal antibody against type A influenza virus nucleoprotein revealed positive staining in the nuclei of the bronchiolar epithelial cells. Lung tissue from three piglets and nasal swabs from five sows and four piglets were positive for influenza A by RT-PCR. Influenza virus was isolated from one lung, later confirmed by the hemagglutination test (HA titer 1: 128) and RT-PCR. Sequence analyses of Hemmaglutinin (HA) and Matrix (M) genes revealed that the virus was consistent with the pandemic (A/H1N1) 2009 influenza virus strain that circulated in humans. This is the first report of an outbreak of pandemic A/H1N1 influenza virus in pigs in Brazil.

AB Rubisco frequently undergoes unproductive interactions with its sugar-phosphate substrate that stabilize active sites in an inactive conformation. Restoring catalytic competence to these sites requires the "molecular chiropractic" activity of Rubisco activase (activase). To make the study of activase more routine and physiologically relevant, an assay was devised for measuring activase activity in leaf extracts based on the ATP-dependent activation of inactive Rubisco. Control experiments with an Arabidopsis activase-deficient mutant confirmed that the rate of Rubisco activation was dependent on the concentration of activase in the extracts. Activase catalyzed Rubisco activation at rates equivalent to 9-14% catalytic sites per min in desalted extracts of Arabidopsis, camelina, tobacco, cotton, and wheat. Faster rates were observed in a transgenic line of Arabidopsis that expresses only the beta-isoform of activase, whereas no activity was detected in a line that expresses only the a-isoform. Activase activity was also low or undetectable in rice, maize, and Chlamydomonas, revealing differences in the stability of the enzyme in different species. These differences are discussed in terms of the ability of activase subunits to remain associated or to reassociate into active oligomers when the stromal milieu is diluted by extraction. Finally, the temperature response of activase activity in leaf extracts differed for Arabidopsis, camelina, tobacco, and cotton, corresponding to the respective temperature responses of photosynthesis for each species. These results confirmed the exceptional thermal lability of activase at physiological ratios of activase to Rubisco.

AB Zinc deficiency is a common problem leading to severe decreases in grain yield and has detrimental effects on nutritional quality in cereals. Wild emmer wheat, Triticum turgidum ssp. dicoccoides, exhibits a potential genetic resource for wheat improvement due to its compatibility with modern wheat. In this study, Zn deficiency response of wild progenitors and modern wheat were examined using molecular and physiological approaches with plants grown under various Zn concentrations. The results revealed wide variation in response to Zn deficiency between wild emmer accessions. Among the wild emmer accessions studied, accession MM 5/4 was found to be most tolerant and accession 19-36 was the most sensitive to Zn deficiency. To better understand Zn transport mechanisms in wild emmer wheat, we analyzed the expression patterns of a ZRT/IRT-like gene, Zrt-, Irt-like protein (ZIP)1, in the roots and shoots of several accessions that were maintained on different concentrations of Zn. Quantitative real-time polymerase chain reaction results revealed that ZIP1 transcript levels are elevated with decreasing Zn supply in all accessions. Particularly, ZIP1 transcript accumulation was lower in the roots of accession MM 5/4 while the susceptible, 19-36 accession, has elevated levels of ZIP1 transcript, revealing a Zn deficiency response for this genotype. We also identified and cloned a full-length ZIP1 transporter, named TdZIP1, and further analyzed the corresponding protein sequence for structural attributes. Under Zn deficiency, deleting the last 20 amino acids from the last transmembrane domain of TdZIP1 and tagging with GFP resulted in endoplasmic reticulum localization. Functional expression of the isolated TdZIP1 using Zn-uptake defective Saccharomyces cerevisiae strains on limiting Zn media showed that it could indeed transport Zn. However, overexpression of this transporter causes excess accumulation of Zn in the cells, thus generating a toxic environment. Overall, our results indicate the possibility of using Triticum dicoccoides for the genetic improvement of zinc deficiency tolerance in wheat.

AB Developing efficient monitoring strategies for species of conservation concern is critical to ensuring their persistence. We have developed a method using camera traps to estimate density and survival in mesocarnivores and tested it on a population of fishers Martes pennanti in an area of approximately 300 km(2) of the southern Sierra Nevada mountains in California. Fishers in this region are isolated from other populations by a gap of approximately 400 km, and the status of individual populations in the southern Sierra Nevada is poorly understood, making management decisions difficult. We caught fishers in live traps, marked them with ear tags, and resighted them with camera traps. We measured latency to first detection and detection rate to compare our results to previous camera trapping studies of fishers. We used the robust design Poisson log-normal mixed-effects mark-resight model to obtain annual estimates of density and apparent survival. Our values for latency to first detection and detection rate were slightly lower than those obtained by previous studies. Fishers in this isolated region occur at lower densities than at other locations across their range with only approximately 6-11 animals/100 km(2). Their average annual, adult survival rate (0.94) was comparable to that found in other studies, though this parameter had very low precision. We experienced relatively high levels of tag loss in our study, suggesting our estimates of abundance are biased upward. We provide recommendations for improving the precision and accuracy of results obtained from this type of study. Our results demonstrate a novel application of mark-resight methods to estimate density and survival for mesocarnivores. These estimates provide timely information to managers about fishers at the local population level in the southern Sierra Nevada mountains.

AB An infestation of Asian longhorned beetle (ALB) (Anoplophora glabripennis (Motschulsky)) was detected in Worcester, Massachusetts, in 2008. The discovery of this pest, previously only seen in urban environments of North America, led to the unprecedented establishment of a 243 km(2) quarantine zone that included urban parks, neighborhoods, and natural forests. Because ALB behavior in forested stands is virtually unknown, two closed-canopied forested stands (Bovenzi and De lava!) infested with ALB within this zone were sampled during 2008-2010 to document stand conditions, assess ALB host selection, and determine ALB impact on tree growth. Thirty-two percent of the Acer sampled in Bovenzi were infested with ALB compared with 63% in Delaval. In Delaval where three maple host species were available, ALB was found more often in Acer rubrum L. than in Acer saccharum Marsh. or Acer platanoides L. Radial growth patterns did not differ between ALB-infested and uninfested Acer trees in Bovenzi. In contrast, ALB-infested trees in De laval were significantly older and larger than uninfested trees and exhibited slower radial growth and ring width index patterns compared with uninfested trees. Results suggest that if left uncontrolled, ALB can readily disperse into natural forest landscapes and alter the makeup of North America's hardwood forest region.

AB Five fumigation treatments (a conventional methyl bromide-chloropicrin application and four reduced-rate alternative fumigant treatments) and a nonfumigated treatment were evaluated at two forest nurseries in Oregon and one forest nursery in Washington for their effects on soil pathogen populations, weeds, and seedling morphology during a 2-year study. The effect of plastic tarp composition on fumigant efficacy was also evaluated (virtually impermeable film versus high-density polyethylene). All fumigant treatments reduced soil populations of Fusarium and Pythium for up to 7 months after fumigation and resulted in seedlings with significantly less pathogen colonization than those from the nonfumigated treatment. All fumigant treatments were more effective against pathogen inoculum buried at 15 cm rather than at 30 cm. Fusarium commune Skovgaard, O'Donnell et Nirenberg, Fusarium agsporum Schlect. emend. Snyder & Hansen, isolates from the Gibberella fujikuroi Saw. complex, Pythium irregulare Buisman, Pythium aff spiculum B. Paul 2006, Pythium sylvaticum Campbell & Hendrix, and Pythium 'vipa' Hermansen & Klemsdal were the most commonly isolated pathogens. Weed biomass and weeding times were significantly reduced by fumigation, but only at the Washington nursery with high weed pressure. No significant differences were observed in efficacy between the conventional methyl bromide-chloropicrin treatment and any of the reduced rate fumigants or between the two types of plastic tarp. Conifer seedling height, diameter, shoot volume, and root volume were significantly greater in all fumigated treatments compared with the nonfumigated treatment.

AB The Russian wheat aphid (RWA) Diuraphis noxia (Mordvilko) is a major pest of winter wheat and barley in the United States. RWA induces stress to the wheat crop by damaging plant foliage, lowering the greenness of plants, and affecting productivity. The utilization of multispectral remote sensing is effective at detecting plant stress in agricultural crops. Stress to wheat plants detected in fields can be caused by several factors that can vary spatially in their presence and intensity across a field. Stress can result from factors such as nutrient deficiency, drought, diseases, and pests that can occur individually or collectively. The present study investigated the potential of using spatial pattern metrics derived from multispectral images in combination with topographic and edaphic variables to identify a set of variables to differentiate the stress induced by RWA from other stress causing factors. A discriminant function analysis was applied to 15 discriminating variables. A set of 13 variables were retained to develop a model to differentiate the three types of stress. Overall, 97 percent of patches of stress used to validate the model were correctly categorized. Stressed patches caused by RWA were 98 percent correctly classified, patches caused by drought were 94 percent correctly classified, and patches caused by agronomic conditions were 99 correctly classified. It is possible to discriminate stress induced by RWA from other stress causing factors in multispectral data when spatial attributes of the stress causing factors are incorporated in the analysis.

AB Although CGE models have received heavy usage - particularly in the analysis of broad-based policies relating to energy, climate and trade, they are often criticized as being insufficiently validated. Key parameters are often not econometrically estimated, and the performance of the model as a whole is rarely checked against historical outcomes. As a consequence, questions frequently arise as to how much faith one can put in CGE results. In this paper, we employ a novel approach to the validation of a widely utilized global CGE model - GTAP-E. By comparing the variance of model-generated petroleum price distributions - driven by historical demand and supply shocks to the model - with observed five-year moving average price distributions, we conclude that energy demand in GTAP-E is far too price-elastic over this medium run time frame. After incorporating the latest econometric estimates of energy demand and supply elasticities, we revisit the validation question and find the model to perform more satisfactorily. As a further check, we compare a deterministic global general equilibrium simulation, based on historical realizations over the five year period: 2001-2006, during which petroleum prices rose sharply, along with growing global energy demands. As anticipated by the stochastic simulations, the revised model parameters perform much better than the original GTAP-E parameters in this global, general equilibrium context.

FORTIFIED MILK
AB Background. Milk and other animal-source foods are concentrated dietary sources of macro- and micronutrients. Despite a global increase in milk production and consumption over the past decades, milk and other animal-source foods are often lacking in the diets of children in developing countries.
Objective. To evaluate the importance of milk and other animal-source food intake in promoting the growth, development, and health of children in low-income countries.
Methods. Original research articles describing observational and intervention studies with unfortified milk, fortified milk, and other animal-source foods in children were identified by searching the PubMed database.
Results. Consumption of milk and other animal-source foods by undernourished children improves anthropometric indices and cognitive function and reduces the prevalence of biochemical and functional nutritional deficiencies, reducing morbidity and mortality. Unfortified and fortified milk used in supplementation trials has been well tolerated and widely accepted by parents and children.
Conclusions. To improve the dietary quality of children in low-income countries and further the effort to eradicate extreme poverty and hunger in accordance with the United Nations Millennium Development Goals, additional research is necessary to identify and implement programs and policy supporting increased intake of milk and other animal-source foods.

AB A Gram-positive, spore-forming, aerobic, filamentous bacterium, strain JFMB-ATE(T), was isolated in 2008 during environmental screening of a plastic surface in grade C in a contract manufacturing organization in southern Germany. The isolate grew at temperatures of 25-50 degrees C and at pH 5.0-8.5, forming ivory-coloured colonies with sparse white aerial mycelia. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the family Thermoactinomycetaceae, except that the cell-wall peptidoglycan contained LL-diaminopimelic acid, while all previously described members of this family display this diagnostic diamino acid in meso-conformation. The DNA G + C content of the novel strain was 54.6 mol%, the main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol, and the major menaquinone was MK-7. The major fatty acids had saturated C(14)-C(16) branched chains. No diagnostic sugars were detected. Based on the chemotaxonomic results and 16S rRNA gene sequence analysis, the isolate is proposed to represent a novel genus and species, Kroppenstedtia eburnea gen. nov. sp. nov. The type strain is JFMB-ATE(T) (=DSM 45196(T) =NRRL B-24804(T) =CCUG 59226(T)).

AB Crustacean cardioactive peptide (CCAP) is a nonapeptide originally isolated from the shore crab. Carcinus maenas, based on its cardioacceleratory activity. This peptide is highly conserved in insects and other arthropods. In insects CCAP also has an essential role in ecdysis behavior. We previously identified two homologous genes, ccapr-1 and ccapr-2, encoding putative CCAP receptors in the red flour beetle, Tribolium castaneum. In contrast, some insects, including Drosophila melanogaster, carry only one gene encoding a CCAP receptor. Phylogenetic analysis of putative CCAP receptor orthologs reveals a number of independent gene duplications in several insect lineages. In this study, we confirmed that CCAP activates both putative T. castaneum receptors in a heterologous expression system. RNA interference (RNAi) of ccapr-1 and ccapr-2 revealed that ccapr-2 is essential for eclosion behavior in T. castaneum, while RNAi for ccapr-1 did not result in any abnormal phenotype. In vivo cardioacceleratory activity of exogenously applied CCAP was abolished by RNAi of ccapr-2, but not by that of ccapr-1. Thus, only ccapr-2 mediates the cardioacceleratory function, ccapr-1 having apparently lost both functions for eclosion behavior and for cardioacceleration since the recent gene duplication event.

AB Purpose. To examine associations between county-level natural amenities, physical activity (PA), and body mass index (BMI).
Design and Setting. Cross-sectional study among 100 North Carolina counties.
Measures. We obtained percentage of county residents meeting PA criteria and county-wide means for reported height and weight from the North Carolina Behavioral Risk Factor Surveillance System, combining years 2003,2005, and 2007. The county natural amenities scale was the independent variable. Potential county-level covariates were percentage rural, percentage black, median age, and median household income (Census 2000).
Analysis. We conducted weighted bivariate and linear regression analyses to examine relationships between natural amenities, aggregate PA, and aggregate BMI
Results. BMI and natural amenities were negatively associated (parameter estimate = -.13 (.06), p = .03). When percentage meeting PA criteria was included, the parameter estimate attenuated 15%.
Conclusion. There was an inverse relationship between natural amenities and BMI, partially mediated by PA. (Am J Health Promot 2011;26[1]:52-55.)

AB Marek's disease (MD) is a lymphoproliferative disorder of domestic chickens caused by a highly contagious and oncogenic alpha-herpesvirus, Marek's disease virus (MDV). MD is characterized by bursal-thymic atrophy and rapid onset of T-cell lymphomas that infiltrate lymphoid tissues, visceral organs, and peripheral nerves with severe clinical signs that include transient paralysis, anemia, weight loss, and neurologic disorders. Using overlapping cosmids- and BAC-cloned MDV, it has been shown that MDV-encoded vIL-8, pp38, vTR, vLIP, RLORF4, and meq are among the many essential genes that play critical roles in viral pathogenesis. Of all the genes investigated so far, only meq has been shown to be consistently expressed in all MDV-derived tumors and lymphoblastoid cell lines. Meq is a basic leucine-zipper protein that shares homology with the jun/fos family of transcriptional factors. There are two copies of meq gene within the MDV genome that are only present in the serotype-1 strains. It has been shown conclusively that deletion of meq results in loss of transformation of T cells in chickens, with no effect on the early cytolytic phase of infection in lymphoid organs, which is essential for induction of innate and adaptive immunity. The goal of this study was to investigate 1) the effect of the meq oncogene on the expression pattern of select chicken immune and nonimmune-related genes, and 2) its potential role in MDV-induced apoptosis. We used real-time reverse transcriptase-polymerase chain reaction to evaluate the expression profiling of a panel of chicken genes in rMd5- and rMd5 Delta meq-infected chickens at 5, 14, 21, and 35 days postinfection (dpi). Although the transcriptional activities of several immune-related genes, including IL-6, IL-10, cMGF, GMCSF, iNOS, IFN beta, and INF gamma, were higher in rMd5 Delta meq-infected chickens at 5 dpi when compared to the rMd5-infected birds, the differences in expression levels of the tested genes between the two viral constructs were not significant. In addition, a reduction in the transcriptional activity of Bcl2 in recombinant fowlpox virus (rFPV)+meq-infected chicken embryonic fibroblasts suggested that meq alone did not impede FPV-induced apoptosis. The likely suppressive nature and anti-inflammatory function of the meq oncogene and its possible role in virus-induced cell death is discussed.

AB Campylobacter spp. are present in organs and tissues of broiler chickens but the dissemination route is unclear. The aim of the current study was to determine Campylobacter prevalence within circulating blood of commercial broilers. Broilers were acquired from 19 flocks originating from three commercial poultry processing companies. Using aseptic blood collection techniques, 5 ml of circulating blood was collected from each bird and the sample analyzed for Campylobacter. The Campylobacter colonization status of each bird was determined by aseptically sampling and analyzing the ceca. Campylobacter was recovered from 58% (11/19) of flocks sampled. From the 248 total birds sampled, 12% and 46% of the birds had Campylobacter in the blood and ceca, respectively. This study documents Campylobacter prevalence in the circulating blood of commercially raised broilers. Campylobacter presence in the circulatory system may indicate the path used by the organism for rapid dissemination to organs and tissues. From a processing viewpoint, Campylobacter presence in circulating blood of market-age broilers may increase the likelihood of cross-contamination between birds during slaughter.

PATHOGENESIS
AB Marek's disease (MD) is a lymphoproliferative disease of domestic chickens caused by a highly infectious, oncogenic alpha-herpesvirus known as Marek's disease virus (MDV). MD is presently controlled by vaccination. Current MD vaccines include attenuated serotype 1 strains (e. g., CVI988/Rispens), avirulent serotype 2 (SB-1), and serotype 3 (HVT) MDV strains. In addition, recombinant MDV strains have been developed as potential new and more efficient vaccines to sustain the success of MD control in poultry. One of the candidate recombinant MDV strains, named rMd5 Delta Meq, was derived from Md5, a very virulent strain of MDV lacking the MDV oncogene Meq. Our earlier reports suggest that rMd5 Delta Meq provided protection equally well or better than commonly used MD vaccines in experimental and commercial lines of chickens challenged with very virulent plus (vv+) strains of MDV. In this study, maternal antibody-positive (trial 1) and negative (trial 2) chickens from a series of relatively MD resistant lines were either vaccinated with the rMd5 Delta Meq or CVI988/Rispens followed by infection of a vv+ strain of MDV, 648A, passage 10. This report presents experimental evidence that the rMd5 Delta Meq protected significantly better than the CVI988/Rispens (P < 0.01) in the relatively resistant experimental lines of chickens challenged with the vv+ strain of MDV. Together with early reports, the rMd5 Delta Meq appeared to provide better protection, comparing with the most efficacious commercially available vaccine, CVI988/Rispens, for control of MD in lines of chickens regardless of their genetic background.

AB Two different wild duck species common in Chile and neighboring countries, Chiloe wigeon (Anas sibilatrix) and cinnamon teal (Anas cyanoptera), were intranasally inoculated with 10(6) mean embryo infective dose (EID(50)) of the H7N3 low pathogenicity (LP) avian influenza virus (AIV) (A/chicken/Chile/176822/02) or high pathogenicity (HP) AIV (A/chicken/Chile/184240-1/02), in order to study the infectivity and pathobiology of these viruses. None of the virus-inoculated ducks had clinical signs or died, but most seroconverted by 14 days postinoculation (DPI), indicating a productive virus infection. Both LPAIV and HPAIV were isolated from oral swabs from two of six Chiloe wigeons and from oral and/or cloacal swabs from all five of the cinnamon teal at 2 DPI. Both LPAIV and HPAIV were efficiently transmitted to cinnamon teal contacts but not to Chiloe wigeon contacts. This study demonstrates that the cinnamon teal and Chiloe wigeons were susceptible to infection with both Chilean H7N3 LPAIV and HPAIV, but only the cinnamon teal showed contact transmission of the virus between birds, suggesting that the cinnamon teal has the potential to be a reservoir for these viruses, especially the LPAIV, as was demonstrated in 2001 with isolation of a genetically related H7N3 LPAIV strain in a cinnamon teal in Bolivia. However, the definitive source of the H7N3 Chilean LPAIV still remains unknown.

ID LAYER CHICKENS
AB Spray application is a commonly used, time- and labor-efficient means to deliver live Mycoplasma gallisepticum (MG) vaccine to laying hens in commercial production facilities. The dosage of vaccine received by spray-vaccinated birds can vary due to variation in the spray plume and the vaccine suspension droplet trajectory. In this study, a total of 48 Hy-Line W-36 males were placed individually in isolation units following eye-drop application of gradient levels (13, 10 213, 10 223, 10 233, 10 243, 10(-5)x, 10(-6)x, and unvaccinated control) of the MG vaccine. The determined titer associated with a 13 dose was 2 x 10(6) colony-forming units/dose. Serologic response was assessed weekly following vaccination via serum plate agglutination (SPA) for weeks one through seven postvaccination (p.v.). In addition, immunologic response was assessed at 5, 6, and 7 wk p.v. via MG enzyme-linked immunosorbent assay (ELISA). As indicated by SPA analyses, a 13 dose of vaccine resulted in 100% seroconversion, and dose levels of 10(-1)x and 10(-2)x resulted in 75% and 37.5% seroconversion, respectively, at 6 wk p.v. The MG ELISA results at 6 wk p. v. demonstrated immunologic responses in 100%, 57.1%, and 28.6% of the 1x, 10(-1)x, and 10(-2)x dosed birds, respectively. The lower dosage levels of 10(-3)x, 10(-4)x, 10(-5)x, and 10(-6)x did not elicit a response from any bird at 6 wk p. v. Utilizing the SPA data, a logistic regression model was used to determine the relationship between dosage level and seroconversion rate (R(2) = 0.999 with a standard error of prediction of 1.6%). The model predicted a required effective dosage of 0.26x for 90% seroconversion at 6 wk p.v. under test conditions.

AB Performance of solid male lure (cuelure (C-L)/raspberry ketone (RK) against Bactrocera tryoni (Froggatt), and methyl eugenol (ME) against oriental fruit fly, B. dorsalis (Hendel)) both formulated with insecticide, were evaluated in Tahiti Island (French Polynesia), as alternatives to current monitoring and control systems using liquid formulations of attractant and organophosphate insecticides. Captures of B. tryoni in traps with BactroMAT C-L stations, Mallet C-L, Mallet MC wafers (containing both ME and RK), and Specialized Pheromone and Lure Application Technology (SPLAT) C-L were as high as with the standard liquid C-L formulation until 8 weeks, but thereafter the effectiveness of Mallet C-L baited traps declined. Captures of B. dorsalis with Mallet ME wafers outperformed any other ME formulation. Traps baited with ME and RK combined in a single Mallet MC wafer captured as many B. tryoni and B. dorsalis as traps baited with a single liquid lure. This suggested that solid Mallet dispensers with RK are longer lasting than those with C-L. For control applications, the weathered SPLAT-MAT-ME-spinosad lure and kill formulation was equal to fresh material for up to 4 weeks. SPLAT C-L was more persistent than weathered SPLAT-MAT-ME under Tahitian climatic conditions, which suggested that SPLAT-MAT-ME may need to be reapplied at shorter intervals and in greater amounts for suppression of B. dorsalis than is required to suppress B. tryoni with SPLAT-MAT-C-L. Mallet ME and MC wafers and SPLAT-MAT-ME/C-L were more convenient and safer to handle than standard liquid insecticide formulations, and should be considered for monitoring and control programs in Pacific island nations. The Mallet MC wafer could be used in a single trap in place of two separate traps for detection of both ME and C-L responding fruit fly species, and thereby reduce trap and labor costs. In addition to the SPLAT-MAT-ME or C-L for control, the Mallet MC wafer in a single trap should be tested further in Florida fruit fly programs.

AB The yellowstriped armyworm (YSAW), Spodoptera ornithogalli (Guenee), has a broad host range and can be an economic threat to cotton in southern growing regions of the United States by consuming leaves and damaging fruiting forms. Field grown cotton varieties containing the endotoxins from Bacillus thuringiensis, (Cry1Ac = Bollgard (R); Cry1Ac + Cry2Ab = Bollgard II (R); Cry1F + Cry1Ac = Widestrike (TM)) and a Non-Bt cotton were evaluated for YSAW susceptibility to cotton leaf tissue. Bioassays conducted at Stoneville, MS, from leaves collected from the lower, middle, and top canopy showed that YSAW were highly susceptible to Bollgard II (R) and WideStrike (TM) traits. No live larvae were collected from the WideStrike (TM) replicated plots and only 2 larvae that weighed 171.5 +/- 53.5 mg were collected from Bollgard II (R) cotton. Larvae collected from Bollgard (R) and Non-Bt cotton were plentiful and averaged 886 +/- 63.5 and 824.25 +/- 51.53 mg, respectively. Additional bioassays from late-season cotton plots at both Stoneville and Weslaco, TX, indicated that WideStrike (TM) and Bollgard II (R) are very active against YSAW larvae. Results from these assays indicate that cotton producers have very effective options for controlling YSAW even late in the growing season.

Both S. exigua and G. boliviana seem to induce plant defenses in tropical soda apple. Significantly more S. exigua neonate larvae survived to second instar on non-induced plants and artificial diet when compared with plants with induced defenses. Our results further suggest that the induced response in TSA was systemic, since BAW neonates suffered higher mortality in induced plants despite not being in direct contact with the damaged part of the plant. Results suggested that feeding action of G. boliviana on TSA had no significant influence on WFT host choice.

AB Improved knowledge of the effects of grass and shrub cover in overland flow can provide valuable information for soil and water conservation programs. Laboratory simulated rainfall studies were conducted to determine effects of grass and shrub on runoff and soil loss and to ascertain the relationship between the rate of soil loss and the unit stream power of runoff for a 20 degrees slope subjected to rainfall intensities of 45, 87, and 127 mm/h. The results indicated that the average runoff rates ranged from 4.2 to 73.1 mm/h for grass plots and from 9.3 to 58.2 mm/h for shrub plots. Runoff rates from shrub plots were less than those from grass plots for all but the 45 mm/h rainfall intensity regime. Average soil loss rates varied from 5.7 to 120.3 g/min.m(2) for grass plots and from 5.6 to 84.4 g/min.m(2) for shrub plots. Soil loss rates from shrub plots were generally lower than those from grass plots. Runoff and soil loss were strongly influenced by soil surface conditions due to the formation of erosion pits and rills. The rate of soil loss increased linearly with the unit stream power of runoff on both grass and shrub plots. Critical unit stream power values were 0.0127 m/s for grass plots and 0.0169 m/s for shrub plots. Shrub plots showed a greater stability to resist soil detachment and transport by surface flow than grass plots.

AB We report the first study of the bacterial microbiome of ovine interdigital skin based on 16S rRNA by pyrosequencing and conventional cloning with Sanger-sequencing. Three flocks were selected, one a flock with no signs of footrot or interdigital dermatitis, a second flock with interdigital dermatitis alone and a third flock with both interdigital dermatitis and footrot. The sheep were classified as having either healthy interdigital skin (H) and interdigital dermatitis (ID) or virulent footrot (VFR). The ovine interdigital skin bacterial community varied significantly by flock and clinical condition. The diversity and richness of operational taxonomic units was greater in tissue from sheep with ID than H or VFR-affected sheep. Actinobacteria, Bacteriodetes, Firmicutes and Proteobacteria were the most abundant phyla comprising 25 genera. Peptostreptococcus, Corynebacterium and Staphylococcus were associated with H, ID and VFR, respectively. Sequences of Dichelobacter nodosus, the causal agent of ovine footrot, were not amplified because of mismatches in the 16S rRNA universal forward primer (27F). A specific real-time PCR assay was used to demonstrate the presence of D. nodosus, which was detected in all samples including the flock with no signs of ID or VFR. Sheep with ID had significantly higher numbers of D. nodosus (10(4)-10(9) cells per g tissue) than those with H or VFR feet.

AB Food loss at the retail and consumer levels in the United States includes 14.8 billion pounds of fruit and 23.4 billion pounds of vegetables, valued at $15.1 billion and $27.7 billion, respectively, in 2008 retail market prices. The total value of these losses is $42.8 billion per year, or roughly $141 per capita. To most efficiently reduce the annual food loss, it may be beneficial to focus efforts on the four fruits (fresh apples, grapes, peaches and strawberries) and four vegetables (fresh and canned tomatoes and fresh and frozen potatoes) that have the greatest amount of loss.

AB Sulfate (SO4) is one of the most important anions in soils and groundwater in semiarid regions, including west Texas. Crops' sulfur (S) requirement is about 10% to 20% of the nitrogen requirements. However, there is far less information on soil test SO4-S (S in the SO4 form [sulfate-S]) for the western United States, compared to the humid eastern United States. The deposition of S from the atmosphere has declined nationwide, as coal-fired power plants have been scrubbing their emissions of S. This, combined with greater cotton yields and the lack of S fertilization on the Texas Southern High Plains (SHP) point to the need for a soil profile SO4-S assessment, The first objective of this study was to assess residual soil profile SO4-S content in irrigated cotton (Gossypium hirsutum) fields across a range of soil types and counties of the Texas SHP The second objective was to compile regional SO4-S concentration data from the Texas Water Development Board irrigation well water quality database and analyze Ogallala groundwater SO4-S levels by county, soil map unit, and well depth. Soil profile (0 to 0.9 m [0 to 36 in]) SO4-S content ranged from 120 to 475 kg ha(-1) (107 to 424 lb ac(-1)) among seven center-pivot fields sampled. About half of this S was in the 0.6 to 0.9 m (24 to 36 in) soil layer, which typically was sandy clay loam or clay loam in texture. Well water SO4-S concentration ranged from 9 to 220 mg L-1 (ppm) in clayey soils with deep groundwater to sandy soils with shallow groundwater, respectively. Groundwater SO4-S concentration was greater than the USEPA drinking water standard of 83 mg L-1 in 32% of the wells, especially in the southeastern corner of the study area. There was no consistent relationship between soil map unit and SO4-S content in the soil profile (0 to 0.9 m). A significant negative relationship between well depth and well water SO4-S concentration was observed in all the eleven-county study area of the SHP of West Texas. In conclusion, soil profile SO4 content to 0.9 m is high in SHP irrigated cotton fields and in most cases should be adequate for crop S nutritional requirements.

AB The effectiveness of erosion control methods is difficult to measure, hampering the development of management practices and preventing accurate assessment of the value of erosion control structures over time. Surface erosion can vary widely over an area, particularly if gully erosion is present, and the use of sediments transported in streams for quantifying erosion is hindered by the highly variable nature of fluvial sediment loads. When a watershed drains into a lake, accumulated sediments have the potential to yield information about historic rates of sedimentation that can be used to evaluate the effectiveness of previous erosion control measures. In the present study, sediments from five natural oxbow cutoff lakes in the Mississippi River alluvial floodplain were dated using lead-210 decay rates and bomb-pulse derived cesium-137 with the goal of relating trends in sedimentation rate to reductions in erosion due to management practices. It was found that the radioisotope dating methods were best used in concert with known dates for implementation of management practices. Changes in sedimentation rate over time frames as short as 12 years were detectable. Larger lakes showed smaller changes in sedimentation rate relative to smaller lakes.

AB Despite widespread adoption of conservation practices by farmers in the Cannonsville watershed, part of the NewYork City water supply system, there is considerable resistance to riparian buffer practices of the Conservation Reserve Enhancement Program (CREP). Traditional approaches to promoting CREP adoption, based on the adoption-diffusion model, were not effective in promoting CREP We surveyed farmers in the Cannonsville watershed to evaluate factors affecting CREP adoption. Many variables commonly tied to practice adoption, including farm structure and farmer sociodemographic traits, were poorly correlated with the attitudes of Cannonsville farmers toward CREP Attitudes toward land costs and farmer resentment toward NewYork City's control of land and conservation policy were, however, strong predictors of CREP adoption. This suggests that as regional watershed collaborations become more active in managing private landowner conservation behaviors, resentment factors may inhibit adoption of the encouraged practices. Findings provide insight into mechanisms to improve upstream-downstream partnerships and the potential to balance clean water resources with local agricultural production priorities.

AB Forest management practices historically have reduced the mass of logging slash to facilitate planting and reduce fire risk. However, coarse woody debris (CWD) is considered an important component of unmanaged forests of western and coastal North America. An experiment was established in northern California using chipped logging slash concentrated in windrows to emulate large fallen logs to determine the effects of alternative logging residue treatments on soil fertility and the performance of planted ponderosa pine. Chip piles warmed faster than mineral soil, but upper regions dried quickly during the dry summers. Fourteen years after planting, growth response was positive, as seedling volume declined with distance from the windrows. After 6 and 10 years, chip samples showed little variation in total C, but total N was higher for 10-year samples, with slightly higher values at the base and for N-fertilized sections. Analysis by solid state (13)C CPMAS NMR, verified by spin-counting and triplicate analysis showed only subtle differences among 10-year samples, with non-carbohydrate C slightly more abundant at the base of the piles and for windrows originally fertilized with N. However, proton spin relaxation editing (PSRE), based on differences in T(1H) relaxation rates, was able to distinguish between C in relatively undecomposed lignocellulose (slowly relaxing) and more decomposed material and microbial residues (rapidly relaxing). The small differences between top and base, and between fertilized and control samples were concentrated in the rapidly relaxing component. Bulk composition of 10-year chip windrows was similar to CWD naturally decomposed by white-rot fungi, but PSRE offers a new approach to monitor spatially heterogeneous development of microsites more characteristic of brown rot.

AB Regulatory risk analysis is designed to provide decisionmakers with a clearer understanding of how policies are likely to affect risk. The systems that produce risk are biological, physical, and social and economic. As a result, risk analysis is an inherently interdisciplinary task. Yet in practice, risk analysis has been interdisciplinary in only limited ways. Risk analysis could provide more accurate assessments of risk if there were better integration of economics and other social sciences into risk assessment itself. This essay examines how discussions about risk analysis policy have influenced the roles of various disciplines in risk analysis. It explores ways in which integrated bio/physical-economic modeling could contribute to more accurate assessments of risk. It reviews examples of the kind of integrated economics-bio/physical modeling that could be used to enhance risk assessment. The essay ends with a discussion of institutional barriers to greater integration of economic modeling into risk assessment and provides suggestions on how these might be overcome.

AB The small hydrophobic protein (SH) is a type II integral membrane protein that is packaged into virions and is only present in certain paramyxoviruses including metapneumovirus. In addition to a highly divergent primary sequence, SH proteins vary significantly in size amongst the different viruses. Human respiratory syncytial virus (HRSV) encodes the smallest SH protein consisting of only 64 amino acids, while metapneumoviruses have the longest SH protein ranging from 174 to 179 amino acids in length. Little is currently known about the cellular localization and topology of the metapneumovirus SH protein. Here we characterize for the first time metapneumovirus SH protein with respect to topology, subcellular localization, and transport using avian metapneumovirus subgroup C (AMPV-C) as a model system. We show that AMPV-C SH is an integral membrane protein with N(in)C(out) orientation located in both the plasma membrane as well as within intracellular compartments, which is similar to what has been described previously for SH proteins of other paramyxoviruses. Furthermore, we demonstrate that AMPV-C SH protein localizes in the endoplasmic reticulum (ER), Golgi, and cell surface, and is transported through ER-Golgi secretory pathway. (C) 2011 Elsevier B.V.

AB Barley yellow dwarf virus-PAV (BYDV-PAV) and cereal yellow dwarf virus-RPV (CYDV-RPV) are only transmitted between host plants by aphid vectors and not by mechanical transmission. This presents a severe limitation for the use of a reverse genetics approach to analyze the effects of mutations in these viruses on plant infection and aphid transmission. Here we describe the use of agroinfection to infect plants with BYDV-PAV and CYDV-RPV. The cDNAs corresponding to the complete RNA genomes of BYDV-PAV and CYDV-RPV were cloned into a binary vector under the control of the cauliflower mosaic virus 35S promoter and the nopaline synthase transcription termination signal. The self-cleaving ribozyme from hepatitis virus D was included to produce a transcript in planta with a 3' terminus identical to the natural viral RNA. ELISA and RT-PCR analysis showed that the replicons of BYDV-PAV and CYDV-RPV introduced by Agrobacterium into Nicotiana benthamiana and N. clevelandii gave rise to a local infection in the infiltrated mesophyll cells. After several weeks systemic infection of phloem tissue was detected, although no systemic symptoms were observed. Three heterologous virus silencing suppressors increased the efficiency of agroinfection and accumulation of BYDV-PAV and CYDV-RPV in the two Nicotiana species. The progeny viruses purified from infiltrated tissues were successfully transmitted to oat plants by aphids, and typical yellow dwarf symptoms were observed. This study reports the first agroinfection of eudicot plants using BYDV-PAV and CYDV-RPV. (C) 2011 Elsevier B.V. All rights reserved.

AB Cotton from a single bale was processed into greige knit fabrics and prepared for dyeing. Following scouring in alkaline solution, fabrics were soaked in either a metal sequestering solution or a water solution, subsequently bleached using hydrogen peroxide, and dyed using Reactive Blue 4. Results indicate that removal of residual Ca(2+) and Mg(2+) from the fabric prior to bleaching results in significant changes in dye uptake. Based upon fabric staining at different stages of preparation using Ruthenium Red, it was shown that removal of Ca(2+) and Mg(2+) prior to bleaching resulted in more effective residual pectin removal from the fabrics.

TI Evaluation of three types of structured floating plastic media in moving
bed biofilters for total ammonia nitrogen removal in a low salinity
hatchery recirculating aquaculture system

AB Three different commercially available structural plastic media were evaluated in triplicate in moving bed biofilters under low salinity (11-12 ppt) warm water culture conditions and two different feed loading rates. The culture system consisted of nine separate modules that include a double drain fish culture tank paired to a moving bed biofilter. The biofilters were filled with 0.11 m(3) of one of three different types of floating plastic structured media. The three types of media evaluated were K1 kaldnes media, MB3 media, and AMB media. Volumetric total ammonia nitrogen (TAN) removal rates (g TAN removed/m(3) media-day). TAN removal efficiency, and biofilm kinetic constants, Kt (h(-1)) were determined for the three media types at two different daily feed load rates of 3.5 and 8.2 kg feed/m(3) media. The feed provided was a 4.8 mm slow sinking marine grower diet pellet (45% protein, 17% fat). Average ( standard deviation, SD) volumetric TAN removal rates (VTR) at the lower feed load for the three media types were 92.2 +/- 26.3, 86.1 +/- 27.5, and 82.5 +/- 25.9 for the MB3, AMB, and K1 kaldnes media, respectively. At the higher feed load the average VTR for the three media types was 186.4 +/- 53.7, 172.9 +/- 47.8, and 139.9 +/- 38.9 for the MB3, AMB, and K1 kaldnes media, respectively. Influent TAN concentrations varied by the feed load rate and ranged from 0.55 to 0.93 mg/L and 0.83 to 1.87 mg/L for the low and higher feed loads, respectively. The percent TAN removal rates for the MB3 media was the highest of the three media types at both the low and high feed load rates averaging 12.3% and 14.4%, respectively. The MB3 media was selected for use in the moving bed biofilters because of the greater VTR and removal efficiency results for use in the 0.11 m(3) moving bed biofilters of the hatchery recirculating aquaculture system.
