A censored demand system which imposes budget constraints in both observed and latent shares is estimated along with a detailed explanation of the estimation procedure. Additional details about the methodology not provided in previous studies should help researchers to empirically apply the model. An innovation of the study is to introduce the censored demand system model for studying the variety of a household's food purchases. Most households buy between seven and eight different products and hardly change the variety of their purchases with changes in meat expenditure.

TI Ecosystem CO2 Exchange in Response to Nitrogen and Phosphorus Addition in a Restored, Temperate Grassland SO AMERICAN MIDLAND NATURALIST LA English DT Article ID CARBON-DIOXIDE EXCHANGE; PRIMARY PRODUCTIVITY; SOIL-MOISTURE; GLOBAL CHANGE; PLANT; LIMITATION; DEPOSITION; WATER; COMMUNITIES; CALIFORNIA AB Nitrogen (N) and phosphorus (P) affect the structure and function of grasslands by altering plant competitive interactions, shifting patterns of above and below ground biomass allocation, and increasing net primary production. However, the influence of N and P on net ecosystem CO2 exchange (NEE) is poorly understood. In a field-based factorial N- and P-addition experiment, we measured shallow soil moisture, leaf area index, and component fluxes of midday ecosystem CO2 exchange throughout the growing season in a restored temperate grassland near Buffalo, New York. Throughout the growing season, N-addition increased gross ecosystem CO2 exchange (GEE) and correspondingly altered NEE to increase ecosystem CO2 uptake. In contrast N-addition caused a seasonally dynamic decline in leaf area adjusted GEE, a pattern consistent with increased photosynthetic light limitation. P-addition did not significantly increase Re, and N- and P-addition interacted to significantly weaken the ecosystem as a midday CO2 sink. Moreover, water limitation and phenological constraints during the middle and late growing season appear to limit plant responses to nutrient addition. These results suggest influences of N -and P-addition on ecosystem processes are seasonally dynamic and by differentially influencing above and below ground components of ecosystems, the availability of N and P in soils may interact to influence ecosystem CO2 exchange.

TI Extended Duration of Parturition Season in North American Elk (Cervus elaphus) SO AMERICAN MIDLAND NATURALIST LA English DT Article ID WHITE-TAILED DEER; FACTORS AFFECTING REPRODUCTION; FEMALE RED DEER; ODOCOILEUS-VIRGINIANUS; CONCEPTION; PREGNANCY; ACCURACY; MONTANA; AGE AB The timing of births in ungulates has significant implications for juvenile survival and population growth. For North American elk (Cervus elaphus), typical parturition season ranges from late May to early Jun., and juveniles born outside of this peak characteristically exhibit lowered survival. We observed abnormally long parturition seasons in free-ranging elk populations in Missouri and South Dakota during 2012. Both populations exhibited late births; the last known births occurred on 26 Sep. in Missouri and 4 Sep. in South Dakota. Duration of parturition season was 112 and 119 d in Missouri and South Dakota, respectively. In Missouri, late births likely resulted from breeding by both yearling females and males. Late parturition in South Dakota may be caused by extended estrous cycles of elk that occurred on high quality range where few adult males were located.

TI Pro-apoptotic gene regulation and its activation by gamma-irradiation in the Caribbean fruit fly, Anastrepha suspensa SO APOPTOSIS LA English DT Article DE Ashid; Asrpr; Irradiation; Ecdysteroids; Cell death; Tephritids ID PROGRAMMED CELL-DEATH; DROSOPHILA EMBRYOS; DNA-DAMAGE; REAPER; HID; METAMORPHOSIS; EXPRESSION; EVOLUTION; HIERARCHY; PROTEIN AB Transcriptional activation of pro-apoptotic genes in response to cytotoxic stimuli is a conserved feature of the cell death pathway in metazoans. However, understanding the extent of this conservation in insects has been limited by the lack of known pro-apoptotic genes in non-drosophilids. Recently, we described the pro-apoptotic genes, Asrpr and Ashid, from the tephritid, Anastrepha suspensa, that now allow us to explore the conservation of pro-apoptotic gene regulation between a tephritid and drosophilids. In this study, we determined the developmental profiles of Asrpr and Ashid transcripts during embryogenesis and in embryos exposed to gamma-irradiation. Transcript levels of both genes determined by qRT-PCR were low throughout embryogenesis, with strong Ashid expression occurring during early to mid-embryogenesis and Asrpr expression peaking in late embryogenesis. This correlated to acridine orange stained apoptotic cells first appearing at 17 h and increasing over time. However, when irradiated at 16 h post-oviposition embryos exhibited significant levels of apoptosis consistent with strong induction of Asrpr and Ashid transcript levels by gamma-irradiation in young embryos < 24 h post-oviposition. Furthermore, embryos irradiated < 24 h post-oviposition failed to hatch, those irradiated between 24 and 32 h had increased hatching rates, but between 48 and 72 h irradiation had no effect on egg hatching. This indicates a transition of embryos from an irradiation-sensitive to irradiation-resistance stage between 24 and 48 h. Throughout post-embryonic development, the two pro-apoptotic genes share similar patterns of up-regulated gene expression, which correlate to ecdysone-induced developmental events, especially during metamorphosis. Together these results provide the first direct evidence for a conserved molecular mechanism of the programmed cell death pathway in insects.

A previously engineered strain of N. crassa (F5) with six of seven beta-glucosidase (bgl) genes knocked out was shown to produce cellobiose and cellobionate directly from cellulose without the addition of exogenous cellulases. In this study, the F5 strain was further modified to improve the yield of cellobiose and cellobionate from cellulose by increasing cellulase production and decreasing product consumption. The effects of two catabolite repression genes, cre-1 and ace-1, on cellulase production were investigated. The F5 Delta ace-1 mutant showed no improvement over the wild type. The F5 Delta cre-1 and F5 Delta ace-1 Delta cre-1 strains showed improved cellobiose dehydrogenase and exoglucanase expression. However, this improvement in cellulase expression did not lead to an improvement in cellobiose or cellobionate production. The cellobionate phosphorylase gene (ndvB) was deleted from the genome of F5 Delta ace-1 Delta cre-1 to prevent the consumption of cellobiose and cellobionate. Despite a slightly reduced hydrolysis rate, the F5 Delta ace-1 Delta cre-1 Delta ndvB strain converted 75% of the cellulose consumed to the desired products, cellobiose and cellobionate, compared to 18% converted by the strain F5 Delta ace-1 Delta cre-1.

However, biocathode mechanistic studies needed to improve or engineer functionality have been limited to a few select species that form sparse, homogeneous biofilms characterized by little or no growth. Attempts to cultivate isolates from biocathode environmental enrichments often fail due to a lack of some advantage provided by life in a consortium, highlighting the need to study and understand biocathode consortia in situ. Here, we present metagenomic and metaproteomic characterization of a previously described biocathode biofilm (+310 mV versus a standard hydrogen electrode [SHE]) enriched from seawater, reducing O-2, and presumably fixing CO2 for biomass generation. Metagenomics identified 16 distinct cluster genomes, 15 of which could be assigned at the family or genus level and whose abundance was roughly divided between Alpha- and Gammaproteobacteria. A total of 644 proteins were identified from shotgun metaproteomics and have been deposited in the the ProteomeXchange with identifier PXD001045. Cluster genomes were used to assign the taxonomic identities of 599 proteins, with Marinobacter, Chromatiaceae, and Labrenzia the most represented. RubisCO and phosphoribulokinase, along with 9 other Calvin-Benson-Bassham cycle proteins, were identified from Chromatiaceae. In addition, proteins similar to those predicted for iron oxidation pathways of known iron-oxidizing bacteria were observed for Chromatiaceae. These findings represent the first description of putative EET and CO2 fixation mechanisms for a self-regenerating, self-sustaining multispecies biocathode, providing potential targets for functional engineering, as well as new insights into biocathode EET pathways using proteomics.

The prevalences and concentrations of these organisms were determined in feces and hides (at feedlot and processing plant), pre-evisceration carcasses, and final carcasses from three lots of fed cattle (n = 184). The prevalences and concentrations were further determined for strip loins from 103 of the carcasses. 3GC(r) Salmonella was detected on 7.6% of hides during processing and was not detected on the final carcasses or strip loins. NALr S. enterica was detected on only one hide. 3GC(r) E. coli and COTr E. coli were detected on 100.0% of hides during processing. Concentrations of 3GC(r) E. coli and COTr E. coli on hides were correlated with pre-evisceration carcass contamination. 3GC(r) E. coli and COTr E. coli were each detected on only 0.5% of final carcasses and were not detected on strip loins. Five hundred and 42 isolates were screened for extraintestinal pathogenic E. coli (ExPEC) virulence-associated markers. Only two COTr E. coli isolates from hides were ExPEC, indicating that fed cattle products are not a significant source of ExPEC causing human urinary tract infections. The very low prevalences of these organisms on final carcasses and their absence on strip loins demonstrate that current sanitary dressing procedures and processing interventions are effective against antimicrobial-resistant bacteria.

SO CANADIAN JOURNAL OF FISHERIES AND AQUATIC SCIENCES LA English DT Article ID TROUT SALMO-TRUTTA; JUVENILE RAINBOW-TROUT; SPAWNING COHO SALMON; ADFLUVIAL BULL TROUT; FLORIDA USA LAKES; BROWN TROUT; TROPHIC STATE; GREAT-LAKES; FOOD WEBS; HABITAT RELATIONSHIPS AB Biased perspectives of fisheries researchers may hinder scientific progress and effective management if limiting factors controlling productivity go unrecognized. We investigated whether river and lake researchers used different approaches when studying salmonid production and whether any differences were ecologically supported. We assessed 564 peer-reviewed papers published between 1966 and 2012 that studied salmonid production or surrogate variables (e. g., abundance, growth, biomass, population) and classified them into five major predictor variable categories: physical habitat, fertility (i. e., nutrients, bottom-up), biotic, temperature, and pollution. The review demonstrated that river researchers primarily analyzed physical habitat (65% of studies) and lake researchers primarily analyzed fertility (45%) and biotic (51%) variables. Nevertheless, understudied variables were often statistically significant predictors of production for lake and river systems and, combined with other evidence, suggests that unjustified a priori assumptions may dictate the choice of independent variables studied. Broader consideration of potential limiting factors on fish production, greater research effort on understudied genera, and increased publication in broadly scoped journals would likely promote integration between lentic and lotic perspectives and improve fisheries management.

TI Cytotype differences in radial increment provide novel insight into aspen reproductive ecology and stand dynamics SO CANADIAN JOURNAL OF FOREST RESEARCH LA English DT Article DE dendroecology; genetic diversity; ploidy; Populus tremuloides; silviculture ID POPULUS-TREMULOIDES; QUAKING ASPEN; GENETIC-VARIATION; GROWTH; CLIMATE; PHYTOCHEMISTRY; PRODUCTIVITY; CALIBRATION; DEFOLIATION; DROUGHT AB High rates of triploidy have recently been described in quaking aspen (Populus tremuloides Michx.) of the Intermountain West, raising questions about the contributions of triploidy to stand persistence and dynamics. In this study, we investigated cytotype differences between diploid and triploid aspen clones using dendrochronological techniques. We used tree-ring data collected from stems within an aspen stand near Fish Lake, Utah, to test for differences in stem age, population structure, growth, and response to climate. This stand contains the well-known Pando clone, which is purported to be the largest organism documented on earth. Our results show that triploid aspen stems grew more rapidly than diploids, and that this difference was most pronounced early in stand development. Growth response to climate varied little between triploids and diploids, where wide rings were associated with cool, moist years, and narrow rings were associated with above-average growing season temperatures. Stand development processes and inherent genetic differences are mechanisms possibly controlling the observed differences in aspen ring width between triploids and diploids. Regardless of the mechanism, the results have specific management implications. Conventional regeneration methods involving coppicing and the associated intermediate treatments will promote asexually reproducing triploids, leading to static or reduced genetic diversity. Enhanced genetic diversity will be favored by management actions that explicitly account for (i) the potential existence of multiple cytotypes within a stand and (ii) the observed differences in growth rates between diploid and triploid individuals.

TI A general method for assessing the effects of uncertainty in individual-tree volume model predictions on large-area volume estimates with a subtropical forest illustration SO CANADIAN JOURNAL OF FOREST RESEARCH LA English DT Article DE allometric model; residual uncertainty; parameter uncertainty; Monte Carlo simulation; Santa Catarina; Brazil ID ALLOMETRIC EQUATIONS; MEASUREMENT ERRORS; TROPICAL FORESTS; INVENTORY DATA; CARBON STOCKS; BIOMASS; SCALE AB Forest inventory estimates of tree volume for large areas are typically calculated by adding the model predictions of volumes for individual trees at the plot level, calculating the mean over plots, and expressing the result on a per unit area basis. The uncertainty in the model predictions is generally ignored, with the result that the precision of the large-area volume estimate is optimistic. The primary study objective was to assess the performance of a Monte Carlo based approach for estimating model prediction error that had been developed for boreal and temperate forest applications when used for a subtropical forest application. Monte Carlo simulation approaches were used because of the complexities associated with multiple sources of uncertainty, the nonlinear nature of the models, and heteroskedasticity. A related objective was to estimate the effects of model prediction uncertainty due to residual and parameter uncertainty on the large-area volume estimates for the Brazilian state of Santa Catarina. The primary conclusions were fourfold. First, the methodological approach worked well. Second, the effects of model residual and parameter uncertainty on large-area estimates of mean volume per unit area were negligible for the models and calibration datasets used for the study. Third, for the models currently in use in Santa Catarina, the effects of model residual and parameter uncertainty may be ignored when calculating large-area estimates of mean volume per unit area. Fourth, differences were negligible between estimates of the mean and standard error obtained using a single, nonspecific volume model and estimates obtained using both forest-type models and species-specific/species-group models.

To evaluate the impact of changes in Ca and Al availability on sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.) growth and forest composition following a major ice storm in 1998, we measured xylem annual increment, foliar cation concentrations, American beech root sprouting, and tree mortality at the Hubbard Brook Experimental Forest (Thornton, New Hampshire) in control plots and in plots amended with Ca or Al (treated plots) beginning in 1995. Dominant sugar maple trees were unaffected by the treatment, but nondominant sugar maple tree growth responded positively to Ca treatment. Although plots were mainly composed of sugar maple, American beech experienced the greatest growth on Al-treated plots. Increases in tree mortality on Al-treated plots may have released surviving American beech and increased their growth. The Al tolerance of American beech and the Ca: Al sensitivity of sugar maple contributed to divergent growth patterns that influenced stand productivity and composition. Given that acidic inputs are expected to continue, the growth dynamics associated with Al treatment may have direct relevance to future conditions in native forests.

Seed oil composition (the types and relative amounts of fatty acids in the oils) may play an important role in determining emergence timing and early growth rate in oilseeds. Saturated fatty acids provide more energy per carbon atom than unsaturated fatty acids but have substantially higher melting points (when chain length is held constant). This characteristic forms the basis of an adaptive hypothesis that lower melting point seeds (lower proportion of saturated fatty acids) should be favored under colder germination temperatures due to earlier germination and faster growth before photosynthesis, while at warmer germination temperatures, seeds with a higher amount of energy (higher proportion of saturated fatty acids) should be favored. To assess the effects of seed oil melting point on timing of seedling emergence and fitness, high- and low-melting point lines from a recombinant inbred cross of Arabidopsis thaliana were competed in a fully factorial experiment at warm and cold temperatures with two different density treatments. Emergence timing between these lines was not significantly different at either temperature, which aligned with warm temperature predictions, but not cold temperature predictions. Under all conditions, plants competing against high-melting point lines had lower fitness relative to those against low-melting point lines, which matched expectations for undifferentiated emergence times.

Assessing wildfire risk entails the integration of fire modeling outputs, maps of highly valued resources and assets (HVRAs), characterization of fire effects, and articulation of relative importance across HVRAs. Quantifying and geoprocessing wildfire risk can be a complex and time-intensive task, often requiring expertise in geospatial analysis. Researchers and land managers alike would benefit from a standardized and streamlined ability to estimate wildfire risk. In this paper we present the development and application of a geospatial wildfire risk calculation tool, FireNVC. We describe the major components of the tool and how they align with a geospatial wildfire risk assessment framework, detail a recent application of the tool to inform federal wildfire management and planning, and offer suggestions for future improvements and uses of the tool.

It is not known if acylcarnitines participate in muscle insulin resistance or simply reflect dysregulated metabolism. The aims of this study were to determine whether acylcarnitines can elicit muscle insulin resistance and to better understand the link between incomplete muscle fatty acid beta-oxidation, oxidative stress, inflammation, and insulin-resistance development. Differentiated C2C12, primary mouse, and human myotubes were treated with acylcarnitines (C4: 0, C14: 0, C16: 0) or with palmitate with or without carnitine acyltransferase inhibition by mildronate. Treatment with C4: 0, C14: 0, and C16: 0 acylcarnitines resulted in 20-30% decrease in insulin response at the level of Akt phosphorylation and/or glucose uptake. Mildronate reversed palmitate-induced insulin resistance concomitant with an similar to 25% decrease in short-chain acylcarnitine and acetylcarnitine secretion. Although proinflammatory cytokines were not affected under these conditions, oxidative stress was increased by 2-3 times by short-or long-chain acylcarnitines. Acylcarnitine-induced oxidative stress and insulin resistance were reversed by treatment with antioxidants. Results are consistent with the conclusion that incomplete muscle fatty acid beta-oxidation causes acylcarnitine accumulation and associated oxidative stress, raising the possibility that these metabolites play a role in muscle insulin resistance.

TI Fetal growth restriction promotes physical inactivity and obesity in female mice SO INTERNATIONAL JOURNAL OF OBESITY LA English DT Article DE developmental origins; developmental programming; body weight regulation; physical activity; energy expenditure; metabolic imprinting ID AGOUTI GENE-EXPRESSION; ENERGY-EXPENDITURE; HYPERCALORIC NUTRITION; MATERNAL OBESITY; WEIGHT-GAIN; PREGNANCY; EXPOSURE; TARGETS; FAMINE; MOUSE AB BACKGROUND: Environmental exposures during critical periods of prenatal and early postnatal life affect the development of mammalian body weight regulatory mechanisms, influencing lifelong risk of obesity. The specific biological processes that mediate the persistence of such effects, however, remain poorly understood. OBJECTIVE: The objectives of this study were to determine the developmental timing and physiological basis of the obesity-promoting effect previously reported in offspring of obese agouti viable yellow (A(vy)/a) mothers. DESIGN: Newborn offspring of obese A(vy)/a and lean (a/a) mothers were cross-fostered shortly after birth to study separately the effects of in utero or suckling period exposure to A(vy)/a dams. Body composition, food intake, physical activity and energy expenditure were measured in offspring shortly after weaning and in adulthood. RESULTS: Offspring of obese A(vy)/a dams paradoxically experienced fetal growth restriction, which was followed by adult-onset obesity specifically in females. Our main analyses focused on wild-type (a/a) offspring, because a subset of adult A(vy)/a offspring contracted a kidney disease resembling diabetic nephropathy. Detailed physiological characterization demonstrated that, both shortly after weaning and in adulthood, female wild-type mice born to A(vy)/a mothers are not hyperphagic but have reduced physical activity and energy expenditure. No such coordinated changes were detected in male offspring. Mediational regression analysis of our longitudinal data supported a causal pathway in which fetal growth restriction persistently reduces physical activity, leading to adult obesity. CONCLUSIONS: Our data are consistent with several recent human epidemiological studies showing female-specific effects of perinatal nutritional restriction on later obesity, and provide the novel mechanistic insight that this may occur via permanent and sex-specific changes in one's inherent propensity for physical activity.

OBJECTIVES To examine the quality and cost of lunches brought from home by elementary and intermediate school students. DESIGN, SETTING, AND PARTICIPANTS An observational studywas conducted in 12 schools (8 elementary and 4 intermediate) in one Houston, Texas, area school district from October 6, 2011, to December 5, 2011. Participants included 242 elementary and 95 intermediate school students who brought lunches from home. EXPOSURES Lunches brought from home. MAIN OUTCOMES AND MEASURES Foods brought and amounts eaten were recorded along with student grade level and sex. Nutrient and food group content were calculated and compared with current National School Lunch Program (NSLP) guidelines. Per-serving prices for each item were collected from 3 grocery stores in the study area and averaged. RESULTS Compared with the NSLP guidelines, lunches brought from home contained more sodium (1110 vs <= 640 mg for elementary and 1003 vs <= 710 mg for intermediate students) and fewer servings of fruits (0.33 cup for elementary and 0.29 cup for intermediate students vs 0.50 cup per the NSLP guidelines), vegetables (0.07 cup for elementary and 0.11 cup for intermediate students vs 0.75 cup per the NSLP guidelines), whole grains (0.22-oz equivalent for elementary and 0.31-oz equivalent for intermediate students vs 0.50-oz minimum per the NLSP guidelines), and fluid milk (0.08 cup for elementary and 0.02 cup for intermediate students vs 1 cup per the NSLP guidelines). About 90% of lunches from home contained desserts, snack chips, and sweetened beverages, which are not permitted in reimbursable school meals. The cost of lunches from home averaged $1.93 for elementary and $1.76 for intermediate students. Students from lower-income intermediate schools brought significantly higher-priced ($1.94) lunches than did students from middle-income schools ($1.63). CONCLUSIONS AND RELEVANCE Lunches brought from home compared unfavorably with current NSLP guidelines. Strategies are needed to improve the nutritional quality of lunches brought from home.

Sixty female, 8-month-old, New Zealand rabbits were randomly assigned for 7 months into five groups as follows: (1) control 1, fed alfalfa hay only (5.91 MJ/kg and 57.5 mg B/kg); (2) control 2, high energy diet (11.76 MJ and 3.88 mg B/kg); (3) B10, high energy diet + 10 mg B gavage/kg body weight/96 h; (4) B30, high energy diet + 30 mg B gavage/kg body weight/96 h; (5) B50, high energy diet + 50 mg B gavage/kg body weight/96 h. Maxillary incisor teeth of the rabbits were evaluated for compression strength, mineral composition, and micro-hardness. Enamel, dentin, cementum and pulp tissue were examined histologically. Mineral densities of the incisor teeth and surrounding alveolar bone were determined by using micro-CT. When compared to controls, the different boron treatments did not significantly affect compression strength, and micro-hardness of the teeth, although the B content of teeth increased in a dose-dependent manner. Compared to control 1, B50 teeth had decreased phosphorus (P) concentrations. Histological examination revealed that teeth structure (shape and thickness of the enamel, dentin, cementum and pulp) was similar in the B-treated and control rabbits. Micro CT evaluation revealed greater alveolar bone mineral density in B10 and B30 groups than in controls. Alveolar bone density of the B50 group was not different than the controls. Although the B treatments did not affect teeth structure, strength, mineral density and micro-hardness, increasing B intake altered the mineral composition of teeth, and, in moderate amounts, had beneficial effects on surrounding alveolar bone.

In response, we have developed MAKER-P, a fast and easy-to-use genome annotation engine for plants. Here, we report the use of MAKER-P to update and revise the maize (Zea mays) B73 RefGen_v3 annotation build (5b+) in less than 3 h using the iPlant Cyberinfrastructure. MAKER-P identified and annotated 4,466 additional, well-supported protein-coding genes not present in the 5b+ annotation build, added additional untranslated regions to 1,393 5b+ gene models, identified 2,647 5b+ gene models that lack any supporting evidence (despite the use of large and diverse evidence data sets), identified 104,215 pseudogene fragments, and created an additional 2,522 noncoding gene annotations. We also describe a method for de novo training of MAKER-P for the annotation of newly sequenced grass genomes. Collectively, these results lead to the 6a maize genome annotation and demonstrate the utility of MAKER-P for rapid annotation, management, and quality control of grasses and other difficult-to-annotate plant genomes.

Effector proteins that mimic plant CLAVATA3/ ENDOSPERM SURROUNDING REGION- related (CLE) proteins have been identified in several cyst nematodes, including the potato cyst nematode (PCN); however, the mechanistic details of this crosskingdom mimicry are poorly understood. Plant CLEs are posttranslationally modified and proteolytically processed to function as bioactive ligands critical to various aspects of plant development. Using ectopic expression coupled with nanoliquid chromatography- tandem mass spectrometry analysis, we show that the in planta mature form of proGrCLE1, a multidomain CLE effector secreted by PCN during infection, is a 12- amino acid arabinosylated glycopeptide (named GrCLE1- 1Hyp4,7g) with striking structural similarity to mature plant CLE peptides. This glycopeptide is more resistant to hydrolytic degradation and binds with higher affinity to a CLAVATA2- like receptor (StCLV2) from potato (Solanum tuberosum) than its nonglycosylated forms. We further show that StCLV2 is highly up- regulated at nematode infection sites and that transgenic potatoes with reduced StCLV2 expression are less susceptible to PCN infection, indicating that interference of the CLV2- mediated signaling pathway confers nematode resistance in crop plants. These results strongly suggest that phytonematodes have evolved to utilize host cellular posttranslational modification and processing machinery for the activation of CLE effectors following secretion into plant cells and highlight the significance of arabinosylation in regulating nematode CLE effector activity. Our finding also provides evidence that multidomain CLEs are modified and processed similarly to single- domain CLEs, adding new insight into CLE maturation in plants.

The pathobiology of these 3 strains was compared to a South African NDV strain classified within genotype VII. All chickens infected with the 4 viruses died or were euthanized by day 4 postinfection due to the severity of clinical signs. Gross and histologic lesions in all infected chickens included extensive necrosis of lymphoid tissues (thymus, spleen, bursa of Fabricius, cecal tonsils, gut-associated lymphoid tissue), gastrointestinal necrosis and hemorrhages, and severe hemorrhagic conjunctivitis. Immunohistochemical staining revealed systemic viral distribution, and the most intense staining was in the lymphoid organs. Results demonstrate that the 3 West African strains from the previously uncharacterized genotypes XIV and XVII are typical velogenic viscerotropic NDV strains with lesions similar to the South African strain. Under experimental conditions, QV4 and LaSota NDV vaccine strains successfully protected chickens from morbidity and mortality against the genotype VII and one genotype XVII NDV strain, with no significant differences in the amount of virus shed when 2 vaccine schemes were compared.

TI Habitual sleep duration is associated with BMI and macronutrient intake and may be modified by CLOCK genetic variants SO AMERICAN JOURNAL OF CLINICAL NUTRITION LA English DT Article DE CLOCK; circadian rhythm; dietary intake; gene-environment interaction; sleep duration ID FOOD-FREQUENCY QUESTIONNAIRE; BODY-MASS INDEX; ENERGY-EXPENDITURE; METABOLIC SYNDROME; METAANALYSIS; ADULTS; OBESITY; SEX; CURTAILMENT; POPULATION AB Background: Short sleep duration has been associated with greater risks of obesity, hypertension, diabetes, and cardiovascular disease. Also, common genetic variants in the human Circadian Locomotor Output Cycles Kaput (CLOCK) show associations with ghrelin and total energy intake. Objectives: We examined associations between habitual sleep duration, body mass index (BM), and macronutrient intake and assessed whether CLOCK variants modify these associations. Design: We conducted inverse-variance weighted, fixed-effect meta-analyses of results of adjusted associations of sleep duration and BMI and macronutrient intake as percentages of total energy as well as interactions with CLOCK variants from 9 cohort studies including up to 14,906 participants of European descent from the Cohorts for Heart and Aging Research in Genomic Epidemiology Consortium. Results: We observed a significant association between sleep duration and lower BMI (beta +/- SE = 0.16 +/- 0.04, P < 0.0001) in the overall sample; however, associations between sleep duration and relative macronutrient intake were evident in age- and sex-stratified analyses only. We observed a significant association between sleep duration and lower saturated fatty acid intake in younger (aged 20-64 y) adults (men: 0.11 +/- 0.06%, P = 0.03; women: 0.10 +/- 0.05%, P = 0.04) and with lower carbohydrate (-0.31 0.12%, P < 0.01), higher total fat (0.18 +/- 0.09%, P = 0.05), and higher PUFA (0.05 +/- 0.02%, P = 0.02) intakes in older (aged 65-80 y) women. In addition, the following 2 nominally significant interactions were observed: between sleep duration and rs12649507 on PUFA intake and between sleep duration and rs6858749 on protein intake. Conclusions: Our results indicate that longer habitual sleep duration is associated with lower BMI and age- and sex-specific favorable dietary behaviors. Differences in the relative intake of specific macronutrients associated with short sleep duration could, at least in part, explain previously reported associations between short sleep duration and chronic metabolic abnormalities. In addition, the influence of obesity-associated CLOCK variants on the association between sleep duration and macronutrient intake suggests that longer habitual sleep duration could ameliorate the genetic predisposition to obesity via a favorable dietary profile.

Researchers have taken different approaches to collecting and analyzing the resulting datasets, with a view toward extracting information on colony behavior and phenology. The objective of this review is to examine critically the different kinds of data and data analyses, providing researchers with better-informed options for obtaining information on colony phenology in the field without disturbing the hive, and for combining information from different kinds of sensors to obtain a more complete picture of colony status. Wireless sensor networks and powering sensors are briefly discussed. C1 [Meikle, W. G.] ARS, USDA, Tucson, AZ 85719 USA. [Holst, N.] Aarhus Univ, Dept Agroecol, DK-4200 Slagelse, Denmark.

Odors derived from animal feeding operations are caused by odorous VOC emitted from the mixture of feces and urine, as well as feed and silage which may be experiencing microbial fermentation. Distillers grains are a by-product of corn grain fermentation used to produce fuel ethanol, and this industry has grown rapidly throughout the U.S. in past years. Therefore, the use of wet distillers grains with solubles (WDGS) in feedlot cattle diets has also increased. The objective of this research was to determine specific VOC emissions from feces and urine or a mixture of both, from cattle fed steam flaked or dry-rolled corn (DRC)-based diets containing either 0% or 30% WDGS. Flux of dimethyl trisulfide was greater from feces of cattle fed DRC than steam-flaked corn (SFC) diets. No other differences in flux from feces were detected across dietary treatments for phenol, 4-methylphenol, indole, skatole, dimethyl disulfide, and flux of volatile fatty acids (VFA) such as acetic, propionic, isobutyric, butyric, isovaleric, and valeric acids (P > 0.15). Flux of skatole, acetic acid, and valeric acid from urine was greater for cattle fed SFC than DRC diets (P < 0.05). Moreover, dimethyl disulfide flux was greater for cattle fed DRC vs. SFC diets (P = 0.05). When evaluating WDGS inclusion in the diet, flux of acetic acid and heptanoic acid from urine was greater when cattle were fed diets containing 0% WDGS than 30% WDGS (P < 0.05). When combining urine and feces in the ratio in which they were excreted from the animal, flux of propionic acid was greater when cattle were fed DRC vs. SFC diets (P = 0.05). Based on these results, the majority of the VOC, VFA, and odor flux from cattle feeding operations is from the urine. Therefore, dietary strategies to reduce odor from cattle feeding facilities should primarily focus on reducing excretion of odorous compounds in the urine. Published by Elsevier Ltd.

The objective of this research was to assess if 8 and 9 years of annual application of untreated or alum-treated poultry litters or ammonium nitrate have resulted in detectable differences in N concentrations and cycling in soil. Soil N concentrations, beta-glucosaminidase activity, and ammonia oxidizer community richness were measured prior to, 10 days, and 1 and 6 months following application in years 8 and 9 in soil receiving either 2.24 (low rate) or 8.96 Mg litter ha(-1) (high rate) or 65 or 260 kg N ha(-1) (approximately equivalent N rates) of ammonium nitrate. There were few effects when fertilizers were applied at the low rate, but soil N did increase in all treatments relative to the control. Soil N, microbial biomass N, and beta-glucosaminidase activity were significantly higher in the alum-treated and untreated poultry litter when applied at the high rate compared to other treatments. Soil inorganic N increased significantly 10 days following application with the high rate of alum-treated litter and ammonium nitrate but not with untreated poultry litter. Ammonia oxidizer community compositions in the high rate of alum-treated and untreated poultry litter treatments were similar to each other and more closely related to the community in the ammonium nitrate treatment than the control. All fertilizers applied at the high rate altered the nitrifier community richness; however, the inputs of both poultry litters increased microbial biomass and enzyme activity, indicators of soil quality.

A 42-day incubation experiment was conducted to study how applications of biochar at different rates (0, 2, 4, and 8 % soil, w/w), in combination with and without mineral KH2PO4 fertilizer, affected contents of soil Olsen-P and soil microbial biomass P (SMB-P) and phosphomonoesterase activity. In addition, P sorption characteristics of soils amended with biochar, as well as main properties of the biochar and the soils, were determined. Application of 8 % biochar after 42 days of incubation substantially increased soil Olsen-P from 3 to 46 mg kg(-1) in Red earth and from 13 to 137 mg kg(-1) in Fluvo-aquic soil and increased SMB-P from 1 to 9 mg kg(-1) in Red earth and from 9 to 21 mg kg(-1) in Fluvo-aquic soil. The increase was mainly due to high concentrations of P in the ash fraction (77 % of total biochar P). Biochar effect on soil Olsen-P and SMB-P increased by higher biochar application rates and by lower P sorption capacity. Biochar application significantly reduced acid phosphomonoesterase activity in Red earth and alkaline phosphomonoesterase activity in Fluvo-aquic soil due to large amount of inorganic P added. We conclude that maize straw biochar is promising to potentially improve soil P availability in low-P soils, but further research at field scale is needed to confirm this.

This study investigated the impacts of simulated acid rain (SAR) upon earthworm activity from the Latosol (acidic red soil). Laboratory experiment was performed by leaching the soil columns grown with earthworms (Eisenia fetida) at the SAR pH levels ranged from 2.0 to 6.5 over a 34-day period. Results showed that earthworms tended to escape from the soil and eventually died for the SAR at pH = 2.0 as a result of acid toxicity. The catalase activity in the earthworms decreased with the SAR pH levels, whereas the superoxide dismutases activity in the earthworms showed a fluctuate pattern: decreasing from pH 6.5 to 5.0 and increasing from pH 5.0 to 4.0. Results implied that the growth of earthworms was retarded at the SAR pH a parts per thousand currency sign 3.0.

The National Center for Cool and Cold Water Aquaculture has bred two genetic lines of rainbow trout: a line of Fp-resistant trout (ARS-Fp-R or R-line trout) and a line of susceptible trout (ARS-Fp-S, or S-line). Little is known about how phenotypic selection alters immune response parameters or how such changes relate to genetic disease resistance. Herein, we quantify interindividual variation in the distribution and abundance of B cell populations (B cell signatures) and examine differences between genetic lines of naive animals. There are limited trout-specific cell surface markers currently available to resolve B cell sub-populations and thus we developed an alternative approach based on detection of differentially expressed transcription factors and intracellular cytokines. B cell signatures were compared between R-line and S-line trout by flow cytometry using antibodies against transcription factors early B cell factor-1 (EBF1) and paired domain box protein Pax5, the pro-inflammatory cytokine IL-1 beta, and the immunoglobulin heavy chain mu. R-line trout had higher percentages of EBF+ B myeloid/progenitor and pre-B cells in PBL, anterior and posterior kidney tissues compared to S-line trout. The opposite pattern was detected in more mature B cell populations: R-line trout had lower percentages of both IgM(+) mature B cells and IgM-secreting cells in anterior kidney and PBL compared to S-line trout. In vitro LPS-activation studies of PBL and spleen cell cultures revealed no significant induction differences between R-line and S-line trout. Together, our findings suggest that selective resistance to BCWD may be associated with shifts in naive animal developmental lineage commitment that result in decreased B lymphopoiesis and increased myelopoiesis in BCWD resistant trout relative to susceptible trout.

In fact, alteration of this gene causes severe immunodeficiency in humans and animals. Although soluble gamma(c) (s gamma(c)) was identified in the late 1990s, much remains unknown about its production. This study describes various mechanisms underlying the generation of s gamma(c) isoforms in different species. Our data demonstrate that mouse gamma(c) and the avian ortholog gamma(c)-a did not generate s gamma(c). Moreover, two mouse isoforms, CRA-a and m gamma(c)-b, encoded by transcripts lacking a transmembrane region by alternative splicing, did not yield s gamma(c). However, in ducks, s gamma(c) was produced from a gamma(c)-b transcript lacking a transmembrane region by alternative splicing. In chickens, s gamma(c) was produced in normal cells and cell lines by proteolytic shedding of the gamma(c)-b isoform containing intron 5, which displayed a relatively high probability of proteolytic cleavage of the ectodomain. This shedding was suppressed by leupeptin, serine and cysteine protease inhibitor. Compared to the chicken ortholog gamma(c)-a, expression of gamma(c)-b mRNA was differentially regulated according to tissue type, developmental stage, and antigen stimulation. These data demonstrate several mechanisms for producing s gamma(c) and suggest a potential role for s gamma(c) in avian lymphoid homeostatic responses to environmental antigens.

This study aimed at enhancing the methods that are currently used in this area by combining plot data from the forest inventory and analysis program of the U.S. Forest Service and free landsat thematic mapper image data. Three mapping methods including linear regression, sequential Gaussian co-simulation, and block co-simulation algorithm were compared with respect to the accuracy of forest carbon stock estimates obtained for a study area in Southern Illinois, USA. The results indicated that although the linear regression resulted in smaller prediction errors than the sequential Gaussian co-simulation and the block co-simulation approaches, it also produced both negative and unreasonably large estimates, which is a serious drawback. Moreover, the sequential Gaussian co-simulation and the block co-simulation produced not only accurate carbon predictions, but also uncertainties for the local estimates. In addition, the block co-simulation approach scaled up both forest carbon stocks and the input uncertainties from finer to coarser spatial resolutions as is required for mapping forest carbon at national and global scales. Thus, the co-simulation and block co-simulation algorithms resolved an important current methodological challenge.

SO GLOBAL CHANGE BIOLOGY LA English DT Review DE altered disturbance regimes; climate change; conifer-northern hardwoods; land use; mesophication; oak-pine forests; subboreal forests ID LAND-USE HISTORY; HEMLOCK-HARDWOOD FORESTS; GREAT-LAKES REGION; WESTERN NEW-YORK; PRESETTLEMENT FORESTS; NEW-ENGLAND; CENTRAL PENNSYLVANIA; DISTURBANCE REGIMES; LANDSCAPE STRUCTURE; NORTHERN MINNESOTA AB Many ecological phenomena combine to direct vegetation trends over time, with climate and disturbance playing prominent roles. To help decipher their relative importance during Euro-American times, we employed a unique approach whereby tree species/genera were partitioned into temperature, shade tolerance, and pyrogenicity classes and applied to comparative tree-census data. Our megadata analysis of 190 datasets determined the relative impacts of climate vs. altered disturbance regimes for various biomes across the eastern United States. As the Euro-American period (ca. 1500 to today) spans two major climatic periods, from Little Ice Age to the Anthropocene, vegetation changes consistent with warming were expected. In most cases, however, European disturbance overrode regional climate, but in a manner that varied across the Tension Zone Line. To the north, intensive and expansive early European disturbance resulted in the ubiquitous loss of conifers and large increases of Acer, Populus, and Quercus in northern hardwoods, whereas to the south, these disturbances perpetuated the dominance of Quercus in central hardwoods. Acer increases and associated mesophication in Quercus-Pinus systems were delayed until mid 20th century fire suppression. This led to significant warm to cool shifts in temperature class where cool-adapted Acer saccharum increased and temperature neutral changes where warm-adapted Acer rubrum increased. In both cases, these shifts were attributed to fire suppression rather than climate change. Because mesophication is ongoing, eastern US forests formed during the catastrophic disturbance era followed by fire suppression will remain in climate disequilibrium into the foreseeable future. Overall, the results of our study suggest that altered disturbance regimes rather than climate had the greatest influence on vegetation composition and dynamics in the eastern United States over multiple centuries. Land-use change often trumped or negated the impacts of warming climate, and needs greater recognition in climate change discussions, scenarios, and model interpretations.

Although studies in grasslands have shown sensitivity of aboveground net primary productivity (ANPP) to both precipitation amount and event size, we lack equivalent knowledge for responses of belowground net primary productivity (BNPP) and NPP. We conducted a 2-year experiment in three US Great Plains grasslands - the C-4-dominated shortgrass prairie (SGP; low ANPP) and tallgrass prairie (TGP; high ANPP), and the C-3-dominated northern mixed grass prairie (NMP; intermediate ANPP) - to test three predictions: (i) both ANPP and BNPP responses to increased precipitation amount would vary inversely with mean annual precipitation (MAP) and site productivity; (ii) increased numbers of extreme rainfall events during high-rainfall years would affect high and low MAP sites differently; and (iii) responses belowground would mirror those aboveground. We increased growing season precipitation by as much as 50% by augmenting natural rainfall via (i) many (11-13) small or (ii) fewer (3-5) large watering events, with the latter coinciding with naturally occurring large storms. Both ANPP and BNPP increased with water addition in the two C-4 grasslands, with greater ANPP sensitivity in TGP, but greater BNPP and NPP sensitivity in SGP. ANPP and BNPP did not respond to any rainfall manipulations in the C-3-dominated NMP. Consistent with previous studies, fewer larger (extreme) rainfall events increased ANPP relative to many small events in SGP, but event size had no effect in TGP. Neither system responded consistently above- and belowground to event size; consequently, total NPP was insensitive to event size. The diversity of responses observed in these three grassland types underscores the challenge of predicting responses relevant to C cycling to forecast changes in precipitation regimes even within relatively homogeneous biomes such as grasslands.

Rice (Oryza sativa), the staple crop for the largest number of people on earth, is grown under flooded soil conditions and uses more water and has higher greenhouse gas (GHG) emissions than most crops. The objective of this study was to test the hypothesis that alternate wetting and drying (AWD - flooding the soil and then allowing to dry down before being reflooded) water management practices will maintain grain yields and concurrently reduce water use, greenhouse gas emissions and arsenic (As) levels in rice. Various treatments ranging in frequency and duration of AWD practices were evaluated at three locations over 2years. Relative to the flooded control treatment and depending on the AWD treatment, yields were reduced by <1-13%; water-use efficiency was improved by 18-63%, global warming potential (GWP of CH4 and N2O emissions) reduced by 45-90%, and grain As concentrations reduced by up to 64%. In general, as the severity of AWD increased by allowing the soil to dry out more between flood events, yields declined while the other benefits increased. The reduction in GWP was mostly attributed to a reduction in CH4 emissions as changes in N2O emissions were minimal among treatments. When AWD was practiced early in the growing season followed by flooding for remainder of season, similar yields as the flooded control were obtained but reduced water use (18%), GWP (45%) and yield-scaled GWP (45%); although grain As concentrations were similar or higher. This highlights that multiple environmental benefits can be realized without sacrificing yield but there may be trade-offs to consider. Importantly, adoption of these practices will require that they are economically attractive and can be adapted to field scales.

Over the past several decades, tropical peatlands have experienced high rates of deforestation and conversion, which is often associated with lowering the water table and peat burning, releasing large amounts of carbon stored in peat to the atmosphere. We present the first model of long-term carbon accumulation in tropical peatlands by modifying the Holocene Peat Model (HPM), which has been successfully applied to northern temperate peatlands. Tropical HPM (HPMTrop) is a one-dimensional, nonlinear, dynamic model with a monthly time step that simulates peat mass remaining in annual peat cohorts over millennia as a balance between monthly vegetation inputs (litter) and monthly decomposition. Key model parameters were based on published data on vegetation characteristics, including net primary production partitioned into leaves, wood, and roots; and initial litter decomposition rates. HPMTrop outputs are generally consistent with field observations from Indonesia. Simulated long-term carbon accumulation rates for 11000-year-old inland, and 5000-year-old coastal peatlands were about 0.3 and 0.59 Mg Cha(-1)yr(-1), and the resulting peat carbon stocks at the end of the 11000-year and 5000-year simulations were 3300 and 2900 Mg Cha(-1), respectively. The simulated carbon loss caused by coastal peat swamp forest conversion into oil palm plantation with periodic burning was 1400 Mg Cha(-1) over 100years, which is equivalent to similar to 2900years of C accumulation in a hectare of coastal peatlands.

Variation in elevation is likely to promote variability in maturation times for species with temperature-dependent development, but it is not known how strongly this influences reproductive asynchrony or the population growth of invasive species. We examined whether spatial variation in reproductive asynchrony, due to differences in elevation and local heterogeneity in elevation (hilliness), can explain spatial heterogeneity in the population growth rate of the gypsy moth, Lymantria dispar (L.), along its invasion front in Virginia and West Virginia, USA. We used a spatially explicit model of the effects of reproductive asynchrony on mating success to develop predictions of the influences of elevation and elevational heterogeneity on local population growth rates. Population growth rates declined with increased elevation and more modestly with increased elevational heterogeneity. As in earlier work, we found a positive relationship between the population growth rate and the number of introduced egg masses, indicating a demographic Allee effect. At high elevations and high heterogeneity in elevation, the population growth rate was lowest and the density at which the population tended to replace itself (i.e. the Allee threshold) was highest. An analysis of 22years of field data also showed decreases in population growth rates with elevation and heterogeneity in elevation that were largely consistent with the model predictions. These results highlight how topographic characteristics can affect reproductive asynchrony and influence mate-finding Allee effects in an invading non-native insect population. Given the dependence of developmental rates on temperature in poikilotherms, topographic effects on reproductive success could potentially be important to the population dynamics of many organisms.

Given the rapidly accumulating and complex contribution of the literature in the field of vitamin D and cognition, clear guidance is needed for researchers and clinicians. MethodsInternational experts met at an invitational summit on Vitamin D and Cognition in Older Adults'. Based on previous reports and expert opinion, the task force focused on key questions relating to the role of vitamin D in Alzheimer's disease and related disorders. Each question was discussed and voted using a Delphi-like approach. ResultsThe experts reached an agreement that hypovitaminosis D increases the risk of cognitive decline and dementia in older adults and may alter the clinical presentation as a consequence of related comorbidities; however, at present, vitamin D level should not be used as a diagnostic or prognostic biomarker of Alzheimer's disease due to lack of specificity and insufficient evidence. This population should be screened for hypovitaminosis D because of its high prevalence and should receive supplementation, if necessary; but this advice was not specific to cognition. During the debate, the possibility of critical periods' during which vitamin D may have its greatest impact on the brain was addressed; whether hypovitaminosis D influences cognition actively through deleterious effects and/or passively by loss of neuroprotection was also considered. ConclusionsThe international task force agreed on five overarching principles related to vitamin D and cognition in older adults. Several areas of uncertainty remain, and it will be necessary to revise the proposed recommendations as new findings become available.

Although obesity is prevalent worldwide, few studies have investigated how obesity interacts with folate status. Objective: Based on data from the NHANES, this study aims to examine the association between body mass index (BM I) and obesity-related metabolic factors with blood folate status. Methods: A nationally representative sample of 3767 adults from the NHANES (2003-2006) was used as the study population. Regression analyses, with and without adjustment for demographic factors and dietary intakes, were performed to examine associations between BMI and metabolic factors with serum and RBC folate. Results: The results indicate serum folate concentrations were lower in obese groups compared to the desirable BM I and overweight categories, paralleling lower intakes in this group. In contrast, RBC folate increased incrementally with BMI. Regression analyses demonstrated an inverse relation between BM I and serum folate but a positive relation for RBC folate (P < 0.01). Waist circumference, serum triglycerides, and fasting plasma glucose each displayed significant positive relations with RBC folate (P < 0.01), although relations with serum folate were not significant and consistent. Conclusions: In summary, obesity is associated with decreased serum folate, which parallels decreased folate intakes. In contrast, obesity is positively associated with RBC folate. Therefore, RBC folate, in addition to serum folate, should also be considered as a critical biomarker for folate status, especially in the obese population. Future research is needed to understand how obesity differentially alters serum and RBC folate status because they are associated with a variety of medical complications.

Objective: Two statistical approaches were used to examine the potential association between egg consumption and adiposity. Methods: Participants (n = 18,987) aged >= 19 y were from the 2001-2008 NHANES who provided 24-h diet recall data, body mass index (BMI) and waist circumference (WC) determined adiposity measures, and blood pressure, circulating insulin, glucose, and lipid concentrations were considered cardiovascular risk factors (CVRFs). Covariate-adjusted least-squares means +/- SEs were generated. Results: The first statistical approach categorized participants into egg consumers or nonconsumers. Consumers had higher mean BMI (in kg/m(2); 28.7 +/- 0.19; P = 0.006) and WC (98 2 +/- 0.43 cm; P= 0.002) than did nonconsumers (28.2 +/- 0.10 and 96.9 +/- 0.23 cm, respectively). Second, cluster analysis identified 8 distinct egg consumption patterns (explaining 39.5% of the variance in percentage of energy within the food categories). Only 2 egg patterns [egg/meat, poultry, fish (MPF)/grains/vegetables and egg/MPF/grains], consumed by <= 2% of the population, drove the association (compared with the no-egg pattern) between egg consumption and BMI and WC. Another analysis controlled for the standard covariates and the other food groups consumed with eggs in those 2 egg patterns. Only the egg/MPF/other-grains pattern remained associated with BM( and WC (both P <= 0.0063). The pattern analyses identified associations between an egg pattern (egg/MPF/other grains/potatoes/other beverages) and diastolic blood pressure (DBP) and serum LDL cholesterol (both <= 0.0063). A final analysis was conducted by adding percentage of energy from fast foods and medication use for diabetes to the covariates. The association between the egg/MPF/grains pattern and BMI and the egg/MPF/potatoes/other beverages and DBP and LDL cholesterol disappeared. Conclusions: Care needs to be taken with data interpretation of diet and health risk factors and the choice of statistical analyses and covariates used in the analyses because these studies are typically used to generate hypotheses. Additional studies are needed to better understand these relations. C1 [Nicklas, Theresa A.] Baylor Coll Med, Dept Pediat, USDA ARS, Childrens Nutr Res Ctr, Houston, TX 77030 USA.

TI Application of a calibrated/validated Agricultural Policy/Environmental eXtender model to assess sediment and nutrient delivery from the Wildcat Creek Mississippi River Basin Initiative-Cooperative Conservation Partnership Initiative SO JOURNAL OF SOIL AND WATER CONSERVATION LA English DT Article DE agriculture conservation practices; Agriculture Policy/Environmental eXtender; Conservation Effects Assessment Project; modeling; watershed ID WATER ASSESSMENT-TOOL; WINTER COVER CROPS; APEX MODEL; NO-TILL; SOIL; PHOSPHORUS; QUALITY; CORN; CALIBRATION; VALIDATION AB Wildcat Creek, a tributary to the Wabash River, was identified by the USDA Natural Resources Conservation Service (NRCS) as a priority watershed for its high sediment and nutrient loading contributions to the Mississippi River. As part of the Mississippi River Basin Initiative (MRBI), the incorporation of conservation practices was implemented through a Cooperative Conservation Partnership Initiative (CCPI) agreement using existing USDA programs. The objective of this work was to evaluate the potential water quality benefits of conservation practices placed in the Wildcat Creek Watershed through the MRBI-CCPI. Specifically, seven output variables (surface runoff, tile flow, sediments, total phosphorus [P], soluble P, soluble nitrogen [N], and soluble N in tile) were compared for four different row crop conservation practices (residue and tillage management no-till, residue and tillage management mulch-till, cover crops, and forage and biomass planting), and two manure application scenarios. Using the Agricultural Policy/Environmental eXtender (APEX) model, calibrated and validated for a field within the St. Joseph River Watershed, a modeling assessment was developed for current conservation practices incorporated at a similar watershed, Wildcat Creek. Annual average values were estimated for each simulated scenario, and percentage reductions were reported. Cover crops consistently reduced sediment and nutrient loads in runoff by more than 50% compared to the tillage baseline scenario, and removal of the manure application in the waste utilization scenario reduced the predicted total and soluble P amounts by 75% and 92%, respectively. When extrapolating the edge-of-field values predicted by the model to the area occupied by each conservation practice throughout the duration of the contracts at the Wildcat Creek Watershed, the total reductions were estimated to be almost 7,000 Mg (7,700 tn) of sediment (68% decrease), 20,000 kg (44,092 lb) of total P (73% decrease), 4,000 kg (8,818.5 lb) of soluble N in runoff (50% decrease), and 185,000 kg (414,00 lb) of soluble N in tile flow (43% decrease). Agricultural Policy/Environmental eXtender modeling is a useful tool for predicting sediment and nutrient loading information at the field-scale, which can be used to calculate the relative impact of conservation practices at the watershed scale when monitoring data are not available. The modeling results confirm the positive impact of these conservation practices and of the MRBI-CCPI initiative at improving water quality at the edge-of-field, and potentially at the Wildcat Creek, the Greater Wabash River Basins, and ultimately the Mississippi River Basin.

TI UTILIZATION OF AGRICULTURAL BY-PRODUCTS TO PARTIALLY REPLACE GELATIN IN PREPARATION OF PRODUCTS FOR LEATHER SO JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION LA English DT Article ID OXIDIZED PHENOLIC-COMPOUNDS; MECHANICAL-PROPERTIES; MODIFIED PROTEINS; FERULIC ACID; TANNIC-ACID; SURIMI; FILMS; GELS AB When polyphenolic-modified gelatin-products were used as fillers, improvements were seen in the subjective properties of the leather. When the treated samples were compared to control samples, there were no significant changes in mechanical properties. At the present time, gelatin is in short supply, costs are increasing, and there is an urgent need to find a substitute that could be combined with the gelatin, thereby, partially replacing and reducing the amount of gelatin required, with the goal that the new products would retain the desired characteristics of gelatin products. We have evaluated the potential of producing biopolymers from the reaction of polyphenols with gelatin in combination with other proteins (e.g. whey) or with carbohydrates (e.g. chitosan and pectin). Several researchers have recently demonstrated the feasibility of these reactions. These combinations would take advantage of the distinctive properties of both species and at the same time create products with improved functional properties. Recently, the preparation of polyphenolic-modified gelatin/whey biopolymer products was investigated, and the results of product characterization using physicochemical analyses indicated optimal products that could be used as fillers. In this continuing study, these products were applied to wet white, that was then finished, and subjective and mechanical properties were evaluated. At the same time a method was developed to determine the rate of uptake of the product. Results of the studies will be presented. These findings could further add to the knowledge of using renewable resources in production of unique products that may have leather processing application. C1 [Taylor, M. M.; Bumanlag, L.

As part of our exploration of tanning mechanisms, we reported previously on interactions of the condensed tannin, quebracho, with powdered hide. In this study, the interactions of chestnut extract, a hydrolyzable tannin, with powdered hide samples are reported and compared with those of the condensed tannin. Hydrothermal stability of powdered hide treated with the hydrolyzable tannin reached a maximum of 75 C at a 40% offer, compared with 84 C for a similar offer of condensed tannin. The hydrolyzable tannin was much more effective at improving collagenase resistance, with nearly complete protection at <10% offer.

Dwyer, Chris TI Cyclic Avian Mass Mortality in the Northeastern United States Is Associated with a Novel Orthomyxovirus SO JOURNAL OF VIROLOGY LA English DT Article ID ARGAS-PERSICARGAS-ARBOREUS; ENVELOPE FUSION PROTEIN; TICK-BORNE VIRUSES; ARANSAS-BAY-VIRUS; INFLUENZA-A; DHORI VIRUS; FAMILY ORTHOMYXOVIRIDAE; HYALOMMA-DROMEDARII; MACQUARIE ISLAND; MEMBRANE-FUSION AB Since 1998, cyclic mortality events in common eiders (Somateria mollissima), numbering in the hundreds to thousands of dead birds, have been documented along the coast of Cape Cod, MA, USA. Although longitudinal disease investigations have uncovered potential contributing factors responsible for these outbreaks, detecting a primary etiological agent has proven enigmatic. Here, we identify a novel orthomyxovirus, tentatively named Wellfleet Bay virus (WFBV), as a potential causative agent of these outbreaks. Genomic analysis of WFBV revealed that it is most closely related to members of the Quaranjavirus genus within the family Orthomyxoviridae. Similar to other members of the genus, WFBV contains an alphabaculovirus gp64-like glycoprotein that was demonstrated to have fusion activity; this also tentatively suggests that ticks (and/or insects) may vector the virus in nature. However, in addition to the six RNA segments encoding the prototypical structural proteins identified in other quaranjaviruses, a previously unknown RNA segment (segment 7) encoding a novel protein designated VP7 was discovered in WFBV. Although WFBV shows low to moderate levels of sequence similarity to Quaranfil virus and Johnston Atoll virus, the original members of the Quaranjavirus genus, additional antigenic and genetic analyses demonstrated that it is closely related to the recently identified Cygnet River virus (CyRV) from South Australia, suggesting that WFBV and CyRV may be geographic variants of the same virus. Although the identification of WFBV in part may resolve the enigma of these mass mortality events, the details of the ecology and epidemiology of the virus remain to be determined. IMPORTANCE The emergence or reemergence of viral pathogens resulting in large-scale outbreaks of disease in humans and/or animals is one of the most important challenges facing biomedicine. For example, understanding how orthomyxoviruses such as novel influenza A virus reassortants and/or mutants emerge to cause epidemic or pandemic disease is at the forefront of current global health concerns. Here, we describe the emergence of a novel orthomyxovirus, Wellfleet Bay virus (WFBV), which has been associated with cyclic large-scale bird die-offs in the northeastern United States. This initial characterization study provides a foundation for further research into the evolution, epidemiology, and ecology of newly emerging orthomyxoviruses, such as WFBV, and their potential impacts on animal and/or human health.

TI Distance, flow and PCR inhibition: eDNA dynamics in two headwater streams SO MOLECULAR ECOLOGY RESOURCES LA English DT Article DE eDNA; environmental DNA; fish; lotic; qPCR; stream ID REAL-TIME PCR; ANTIBIOTIC-RESISTANCE GENES; ENVIRONMENTAL DNA; DIAGNOSTIC PCR; WATER SAMPLES; BROOK TROUT; ORGANIC-MATTER; IDAHO STREAMS; TRANSPORT; AMPLIFICATION AB Environmental DNA (eDNA) detection has emerged as a powerful tool for monitoring aquatic organisms, but much remains unknown about the dynamics of aquatic eDNA over a range of environmental conditions. DNA concentrations in streams and rivers will depend not only on the equilibrium between DNA entering the water and DNA leaving the system through degradation, but also on downstream transport. To improve understanding of the dynamics of eDNA concentration in lotic systems, we introduced caged trout into two fishless headwater streams and took eDNA samples at evenly spaced downstream intervals. This was repeated 18 times from mid-summer through autumn, over flows ranging from approximately 1-96L/s. We used quantitative PCR to relate DNA copy number to distance from source. We found that regardless of flow, there were detectable levels of DNA at 239.5m. The main effect of flow on eDNA counts was in opposite directions in the two streams. At the lowest flows, eDNA counts were highest close to the source and quickly trailed off over distance. At the highest flows, DNA counts were relatively low both near and far from the source. Biomass was positively related to eDNA copy number in both streams. A combination of cell settling, turbulence and dilution effects is probably responsible for our observations. Additionally, during high leaf deposition periods, the presence of inhibitors resulted in no amplification for high copy number samples in the absence of an inhibition-releasing strategy, demonstrating the necessity to carefully consider inhibition in eDNA analysis.

TI The beet Y locus encodes an anthocyanin MYB-like protein that activates the betalain red pigment pathway SO NATURE GENETICS LA English DT Article ID TRANSCRIPTION FACTORS; ARABIDOPSIS-THALIANA; TABLE BEET; IDENTIFICATION; BIOSYNTHESIS; EXPRESSION; EVOLUTION; GENES; CARYOPHYLLALES; SPECIFY AB Nearly all flowering plants produce red/violet anthocyanin pigments. Caryophyllales is the only order containing families that replace anthocyanins with unrelated red and yellow betalain pigments(1,2). Close biological correlation of pigmentation patterns suggested that betalains might be regulated by a conserved anthocyanin-regulating transcription factor complex consisting of a MYB, a bHLH and a WD repeat-containing protein (the MBW complex)(3). Here we show that a previously uncharacterized anthocyanin MYB-like protein, Beta vulgaris MYB1 (BvMYB1), regulates the betalain pathway in beets. Silencing BvMYB1 downregulates betalain biosynthetic genes and pigmentation, and overexpressing BvMYB1 upregulates them. However, unlike anthocyanin MYBs, BvMYB1 will not interact with bHLH members of heterologous anthocyanin MBW complexes because of identified nonconserved residues. BvMYB1 resides at the historic beet pigment-patterning locus, Y, required for red-fleshed beets(4). We show that Y and y express different levels of BvMYB1 transcripts. The co-option of a transcription factor regulating anthocyanin biosynthesis would be an important evolutionary event allowing betalains to largely functionally replace anthocyanins.

TI Time series analysis of forest carbon dynamics: recovery of Pinus palustris physiology following a prescribed fire SO NEW FORESTS LA English DT Article DE Longleaf pine; Net ecosystem exchange (NEE); Ecosystem respiration (Reco); Gross ecosystem exchange (GEE); Prescribed fire; ARIMA models ID CANADIAN BOREAL FOREST; LONGLEAF PINE; NORTH FLORIDA; TERRESTRIAL ECOSYSTEMS; STAND AGE; PRODUCTIVITY; VEGETATION; SOIL; SAVANNAS; IMPACT AB Frequency and intensity of fire determines the structure and regulates the function of savanna ecosystems worldwide, yet our understanding of prescribed fire impacts on carbon in these systems is rudimentary. We combined eddy covariance (EC) techniques and fuel consumption plots to examine the short-term response of longleaf pine forest carbon dynamics to one prescribed fire at the ends of an edaphic gradient (mesic and xeric sites). We also introduce novel (to the EC research community) statistical time-series approaches to quantify the drivers of carbon dynamics in these systems. We determined that our mesic site was a moderate sink of carbon (-157.7 +/- A 25.1 g C m(-2) year(-1)), while the xeric site was carbon neutral (5.9 +/- A 32.8 g C m(-2) year(-1)) during the study. The fire released 408 and 153 g C m(-2) year(-1) for the mesic and xeric sites, respectively. When loss associated with fire was combined with net ecosystem exchange rates, both sites became moderate carbon sources for the year. Analyses of assimilation and respiration parameters (e.g., maximum photosynthesis, quantum efficiency, and daytime ecosystem respiration) showed a positive trend over time pre-fire and a negative trend over time post-fire for maximum ecosystem CO2 uptake rates, and the opposite relationship for daytime ecosystem respiration rates. Within 30 days following fire, ecosystem physiological activity was statistically similar to pre-fire and appeared to be driven by the pine canopy. Our results suggest that prescribed fire (low intensity, high frequency) maintains the existing structure and function (in this case, carbon flux rates) because longleaf pine ecosystems have evolved with fire. This study, 1 year in length, provides a foundational understanding of the complex interaction between fire and carbon dynamics for longleaf pine ecosystems. Moreover, it provides a case study for applying time series analysis methods to EC data where there are complex relationships between ecosystem physiological activity and environmental drivers. However, to elicit a broader understanding of the complex interaction occurring between fire and carbon dynamics long- term studies are needed. C1 [Starr, G.; Staudhammer, C.

Analysis of miRNAs and other classes of small RNAs (sRNAs) in barley grown under water and drought conditions reveals that drought selectively regulates expression of miRNAs and other classes of sRNAs. Low-expressed miRNAs and all repeat-associated siRNAs (rasiRNAs) tended towards down-regulation, while tRNA-derived sRNAs (tsRNAs) had the tendency to be up-regulated, under drought. Antisense sRNAs (putative siRNAs) did not have such a tendency under drought. In drought-tolerant transgenic barley overexpressing DREB transcription factor, most of the low-expressed miRNAs were also down-regulated. In contrast, tsRNAs, rasiRNAs and other classes of sRNAs were not consistently expressed between the drought-treated and transgenic plants. The differential expression of miRNAs and siRNAs was further confirmed by Northern hybridization and quantitative real-time PCR (qRT-PCR). Targets of the drought-regulated miRNAs and siRNAs were predicted, identified by degradome libraries and confirmed by qRT-PCR. Their functions are diverse, but most are involved in transcriptional regulation. Our data provide insight into the expression profiles of miRNAs and other sRNAs, and their relationship under drought, thereby helping understand how miRNAs and sRNAs respond to drought stress in cereal crops.

The resistance (R) gene R (Mc1(blb)) confers resistance against the plant-parasitic nematode, Meloidogyne chitwoodi. Avirulent and virulent nematodes were used to functionally characterize the R (Mc1(blb))-mediated resistance mechanism in potato (Solanum tuberosum). Histological observations indicated a hypersensitive response (HR) occurred during avirulent nematode infection. This was confirmed by quantifying reactive oxygen species activity in response to avirulent and virulent M. chitwoodi. To gain an insight into the signal transduction pathways mediating the R (Mc1(blb))-induced HR, chemical inhibitors were utilized. Inhibiting Ca2+ channels caused a significant reduction in electrolyte leakage, an indicator of cell death. Labeling with a Ca2+-sensitive dye revealed high Ca2+ levels in the root cells surrounding avirulent nematodes. Furthermore, the calcium-dependent protein kinase (CDPK), StCDPK4 had a higher transcript level in R (Mc1(blb)) potato roots infected with avirulent nematodes in comparison to roots infected with virulent M. chitwoodi. The results of this study indicate Ca2+ plays a role in the R (Mc1(blb))-mediated resistance against M. chitwoodi in potato.

TI Identification and evaluation of quantitative trait loci underlying resistance to multiple HG types of soybean cyst nematode in soybean PI 437655 SO THEORETICAL AND APPLIED GENETICS LA English DT Article ID HETERODERA-GLYCINES ICHINOHE; COPY NUMBER VARIATION; GENETIC-LINKAGE MAP; SCN RESISTANCE; RACES 1; POPULATIONS; QTL; RHG1; PI-88788 AB We performed QTL analysis for SCN resistance in PI 437655 in two mapping populations, characterized CNV of Rhg1 through whole-genome resequencing and evaluated the effects of QTL pyramiding to enhance resistance. Soybean cyst nematode (SCN, Heterodera glycines Ichinohe) is one of the most serious pests of soybean worldwide. PI 437655 has broader resistance to SCN HG types than PI 88788. The objectives of this study were to identify quantitative trait loci (QTL) underlying SCN resistance in PI 437655, and to evaluate the QTL for their contribution to SCN resistance. Two F-6:7 recombinant inbred line populations, derived from cv. Williams 82 x PI 437655 and cv. Hutcheson x PI 437655 crosses, were evaluated for resistance to SCN HG types 1.2.5.7 (PA2), 0 (PA3), 1.3.5.6.7 (PA14), and 1.2.3.4.5.6.7 (LY2). The 1,536 SNP array was used to genotype the mapping populations and construct genetic linkage maps. Two significant QTL were consistently mapped on chromosomes (Chr.) 18 and 20 in these two populations. One QTL on Chr. 18, which corresponds to the known Rhg1 locus, contributed resistance to SCN HG types 1.2.5.7, 0, 1.3.5.6.7, and 1.2.3.4.5.6.7 (PA2, PA3, PA14, and LY2, respectively). Copy number variation (CNV) analysis by whole-genome resequencing showed that PI 437655 and PI 88788 had similar CNV at the Rhg1 locus. The QTL on Chr. 20 contributed resistance to SCN HG types 1.3.5.6.7 (PA14) and 1.2.3.4.5.6.7 (LY2). Evaluation of both QTL showed that pyramiding of Rhg1 and the QTL on Chr. 20 significantly improved the resistance to SCN HG types 1.3.5.6.7 (PA14) and 1.2.3.4.5.6.7 (LY2) in both populations. Our studies provided useful information for deploying PI 437655 as a donor for SCN resistance in soybean breeding through marker-assisted selection.

MELO; QTL ANALYSIS; FRUIT SHAPE; CROP DOMESTICATION; DNA-SEQUENCES; GENETIC-BASIS; GENOME; EVOLUTION AB Comparative genetic mapping revealed the origin of Xishuangbanna cucumber through diversification selection after domestication. QTL mapping provided insights into the genetic basis of traits under diversification selection during crop evolution. The Xishuangbanna cucumber, Cucumis sativus L. var. xishuangbannanesis Qi et Yuan (XIS), is a semi-wild landrace from the tropical southwest China with some unique traits that are very useful for cucumber breeding, such as tolerance to low light, large fruit size, heavy fruit weight, and orange flesh color in mature fruits. In this study, using 124 recombinant inbred lines (RILs) derived from the cross of the XIS cucumber with a cultivated cucumber inbred line, we developed a linkage map with 269 microsatellite (or simple sequence repeat) markers which covered 705.9 cM in seven linkage groups. Comparative analysis of orders of common marker loci or marker-anchored draft genome scaffolds among the wild (C. sativus var. hardwickii), semi-wild, and cultivated cucumber genetic maps revealed that the XIS cucumber shares major chromosomal rearrangements in chromosomes 4, 5, and 7 between the wild and cultivated cucumbers suggesting that the XIS cucumber originated through diversifying selection after cucumber domestication. Several XIS-specific minor structural changes were identified in chromosomes 1 and 6. QTL mapping with the 124 RILs in four environments identified 13 QTLs for domestication and diversifying selection-related traits including 2 for first female flowering time (fft1.1, fft6.1), 5 for mature fruit length (fl1.1, fl3.1, fl4.1, fl6.1, and fl7.1), 3 for fruit diameter (fd1.1, fd4.1, and fd6.1), and 3 for fruit weight (fw2.1, fw4.1, and fw6.1). Six of the 12 QTLs were consistently detected in all four environments. Among the 13 QTLs, fft1.1, fl1.1, fl3.1, fl7.1, fd4.1, and fw6.1 were major-effect QTLs for respective traits with each explaining at least 10 % of the observed phenotypic variations. Results from this study provide insights into the cytological and genetic basis of crop evolution leading to the XIS cucumber. The molecular markers associated with the QTLs should be useful in exploring the XIS cucumber genetic resources for cucumber breeding.

TI Genome-wide association study (GWAS) of carbon isotope ratio (delta C-13) in diverse soybean [Glycine max (L.)

Water deficit stress is a major factor limiting soybean [Glycine max (L.) Merr.] yield. Soybean genotypes with improved water use efficiency (WUE) may be used to develop cultivars with increased yield under drought. A collection of 373 diverse soybean genotypes was grown in four environments (2 years and two locations) and characterized for carbon isotope ratio (delta C-13) as a surrogate measure of WUE. Population structure was assessed based on 12,347 single nucleotide polymorphisms (SNPs), and genome-wide association studies (GWAS) were conducted to identify SNPs associated with delta C-13. Across all four environments, delta C-13 ranged from a minimum of -30.55 aEuro degrees to a maximum of -27.74 aEuro degrees. Although delta C-13 values were significantly different between the two locations in both years, results were consistent among genotypes across years and locations. Diversity analysis indicated that eight subpopulations could contain all individuals and revealed that within-subpopulation diversity, rather than among-subpopulation diversity, explained most (80 %) of the diversity among the 373 genotypes. A total of 39 SNPs that showed a significant association with delta C-13 in at least two environments or for the average across all environments were identified by GWAS. Fifteen of these SNPs were located within a gene. The 39 SNPs likely tagged 21 different loci and demonstrated that markers for delta C-13 can be identified in soybean using GWAS. Further research is necessary to confirm the marker associations identified and to evaluate their usefulness for selecting genotypes with increased WUE.

Maximizing the phenotypic variance captured by the training set is important for optimal performance. The optimization of the training set (TRS) in genomic selection has received much interest in both animal and plant breeding, because it is critical to the accuracy of the prediction models. In this study, five different TRS sampling algorithms, stratified sampling, mean of the coefficient of determination (CDmean), mean of predictor error variance (PEVmean), stratified CDmean (StratCDmean) and random sampling, were evaluated for prediction accuracy in the presence of different levels of population structure. In the presence of population structure, the most phenotypic variation captured by a sampling method in the TRS is desirable. The wheat dataset showed mild population structure, and CDmean and stratified CDmean methods showed the highest accuracies for all the traits except for test weight and heading date. The rice dataset had strong population structure and the approach based on stratified sampling showed the highest accuracies for all traits. In general, CDmean minimized the relationship between genotypes in the TRS, maximizing the relationship between TRS and the test set. This makes it suitable as an optimization criterion for long-term selection. Our results indicated that the best selection criterion used to optimize the TRS seems to depend on the interaction of trait architecture and population structure.

Impacts have been considered primarily aesthetic because leaf miners cause leaves of birch trees (Betula spp.) to senesce prematurely, but the leaf miners likely also reduce birch vigour and thereby increase susceptibility to diseases and other insects. We tested the ability of commercially available biological control agents to control P. thomsoni. The entomopathogenic fungus Beauveria bassiana (Bals.-Criv.) Vuillemin GHA strain and the entomopathogenic nematode Steinernema carpocapsae (Weiser) were applied in aqueous suspension to the soil/litter surface beneath infested birch trees in Alaska at one site in 2007 and 2008 and two sites in 2010. There was no evidence the fungus or nematode controlled P. thomsoni. Instead, there was evidence the fungus increased the density of this pest insect at two sites, likely by reducing its predators. As tested, B. bassiana and S. carpocapsae do not appear effective as biological controls of P. thomsoni. C1 [Progar, R. A.] US Forest Serv, USDA, Pacific NW Res Stn, La Grande, OR 97850 USA.

To improve food safety, pathogen control is of immediate concern. The aim of this research was to assess the populations of natural microflora (aerobic mesophilic bacteria, lactic acid bacteria, yeasts and moulds and Pseudomonas species) on tomatoes, and evaluate the efficacy of Pseudomonas fluorescens (Pf) and Pseudomonas chlororaphis (Pc) for inactivation of Salmonella on tomatoes. Microflora were determined on sanitised and unsanitised produce and enumerated on Plate Count Agar, de Man, Rogosa and Sharpe medium, Potato Dextrose Agar and Pseudomonas Agar F media. The efficacy of Pc and Pf for inactivation of S. enterica serovars Montevideo, Typhimurium and Poona was determined on spot-inoculated tomato stem scars. The effects of storage time on bacterial populations were also investigated. On unsanitised tomatoes, lactic acid bacteria, Pseudomonas sp., aerobic mesophilic bacteria and yeasts and moulds ranged from 3.31-4.84, 3.93-4.77, 4.09-4.80 and 3.83-4.67 log CFU/g of produce, respectively. The microflora were similar at 0 and 24 storage hours on sanitised produce. The suppression of Salmonella Montevideo by P. chlororaphis and P. fluorescens on tomatoes ranged from 0.51 to 2.00 log CFU/g of produce. On Salmonella Montevideo and S. Typhimurium, the suppressive effects ranged from 0.51 to 0.95 and 0.46 to 2.00 log CFU/g of produce, respectively. The pathogen suppressive effects may be attributed to competition ability of Pseudomonas relative to Salmonella strains. Pseudomonas strains may be effective against Salmonella strains as a post-harvest application, but strain synergy is required to optimise pathogen reductions. C1 [Olanya, O.

The advent of high throughput sequencing technology provides the potential to generate mtgenomes for many species affordably and quickly. However, these technologies need to be validated for dipterans as the members of this clade play important economic and research roles. Illumina and 454 sequencing platforms are widely used in genomic research involving non-model organisms. The Illumina platform has already been utilized for generating mitochondrial genomes without using conventional long range PCR for insects whereas the power of 454 sequencing for generating mitochondrial genome drafts without PCR has not yet been validated for insects. Thus, this study examines the utility of 454 sequencing approach for dipteran mtgenomic research. We generated complete or nearly complete mitochondrial genomes for Cochliomyia hominivorax, Haematobia irritans, Phormia regina and Sarcophaga crassipalpis using a 454 sequencing approach. Comparisons between newly obtained and existing assemblies for C. hominivorax and H. irritans revealed no major discrepancies and verified the utility of 454 sequencing for dipteran mitochondrial genomes. We also report the complete mitochondrial sequences for two forensically important flies, P. regina and S. crassipalpis, which could be used to provide useful information to legal personnel. Comparative analyses revealed that dipterans follow similar codon usage and nucleotide biases that could be due to mutational and selection pressures. This study illustrates the utility of 454 sequencing to obtain complete mitochondrial genomes for dipterans without the aid of conventional molecular techniques such as PCR and cloning and validates this method of mtgenome sequencing in arthropods.

Results indicated that fibres play a major role in longitudinal tension and impeding crack radial propagation. Hybrid I-II failure mode was observed, i.e., crack opening (in tensile stress) and shear sliding (in shear stress). According to microscopic fracture characteristics, fibres extraction and stretching, filament formation in parenchyma with fibres bridging, interface debonding and the helix fracture of fibres happened in tension, which created more interfaces and dissipated more energy. The graded composite structure of bamboo provides intrinsic and extrinsic toughening mechanisms which contribute to improved toughness and physical properties.

Guarding against the introduction of screwworms to North America or any other screwworm-free area relies on rapid, reliable identification of suspected cases. In the current study, the DNA from excised markers generated by randomly amplified polymorphic DNA polymerase chain reaction was used as the basis to generate 2 species-specific sequence-characterized amplified region molecular markers. Resulting primer pairs, named CR92A1 and J1A2 (each with forward and reverse components), produced amplicons of 852 and 848 base pairs, respectively. The 2 primer pairs successfully discriminated between C. hominivorax, Cochliomyia macellaria (Fabricius, 1775), 8 other species of blowflies, 3 noncalliphorid dipterans, and 1 nondipteran outlier. These primers may become important tools for veterinary laboratories and the screwworm eradication and exclusion program for rapid identification or verification of suspicious larval samples in presumed outbreaks.

TI Pine needle abortion biomarker detected in bovine fetal fluids SO JOURNAL OF VETERINARY DIAGNOSTIC INVESTIGATION LA English DT Article DE Abortion; cattle; isocupressic acid; pine needle; tetrahydroagathic acid ID PONDEROSA PINE; ISOCUPRESSIC ACID; ABORTIFACIENT COMPOUNDS; BEEF-COWS; CATTLE; INGESTION; METABOLISM; COMPOUND AB Pine needle abortion is a naturally occurring condition in free-range cattle caused by the consumption of pine needles from select species of cypress, juniper, pine, and spruce trees. Confirmatory diagnosis of pine needle abortion has previously relied on a combined case history of pine needle consumption and detection of isocupressic acid in a sample from the dam. Stable metabolites of isocupressic acid include agathic acid, dihydroagathic acid, and tetrahydroagathic acid, which have been shown to be present in the serum of mature animals for a few days following consumption of pine needles. As maternal serum is infrequently submitted for diagnosis of cattle abortions, a diagnostic assay capable of confirming isocupressic acid exposure in other matrices would be desirable. To the authors' knowledge, no previous investigations have indicated whether these stable metabolites of isocupressic acid cross the placenta or are detectable in fetal tissues. Therefore, the presence of agathic acid, dihydroagathic acid, and tetrahydroagathic acid was evaluated using gas chromatography-mass spectroscopy on fetal thoracic fluid and stomach contents collected from 2 aborted bovine fetuses with a recent herd history of pine needle consumption by the dams and a subsequent abortion outbreak in the herd. Only tetrahydroagathic acid was detected in the fetal thoracic fluid and fetal stomach contents. The current study encourages diagnosticians to collect fetal thoracic fluids to permit the detection of tetrahydroagathic acid in cases of suspected pine needle abortion.

TI Enteric disease in postweaned beef calves associated with Bovine coronavirus clade 2 SO JOURNAL OF VETERINARY DIAGNOSTIC INVESTIGATION LA English DT Article DE Beef cattle; Bovine coronavirus; enteric disease ID WINTER DYSENTERY; FEEDLOT; CATTLE; INFECTIONS AB Bovine coronavirus (BoCV; Betacoronavirus 1) infections are associated with varied clinical presentations including neonatal diarrhea, winter dysentery in dairy cattle, and respiratory disease in various ages of cattle. The current report presents information on BoCV infections associated with enteric disease of postweaned beef cattle in Oklahoma. In 3 separate accessions from a single herd, 1 in 2012 and 2 in 2013, calves were observed with bloody diarrhea. One calf in 2012 died and was necropsied, and 2 calves from this herd died in 2013 and were necropsied. A third calf from another herd died and was necropsied. The gross and histologic diagnosis was acute, hemorrhagic colitis in all 4 cattle. Colonic tissues from all 4 animals were positive by fluorescent antibody testing and/or immunohistochemical staining for BoCV antigen. Bovine coronavirus was isolated in human rectal tumor cells from swabs of colon surfaces of all animals. The genomic information from a region of the S envelope region revealed BoCV clade 2. Detection of BoCV clade 2 in beef cattle in Oklahoma is consistent with recovery of BoCV clade 2 from the respiratory tract of postweaned beef calves that had respiratory disease signs or were healthy. Further investigations on the ecology of BoCV in cattle are important, as BoCV may be an emerging disease beyond the initial descriptions. Challenge studies are needed to determine pathogenicity of these strains, and to determine if current BoCV vaccines are efficacious against the BoCV clade 2 strains.

Manipulative studies allow for strong inference on effects and confirmation of patterns from observational studies. We estimated bird-territory density within forest stands (2.89-62ha) for 19 years of the Missouri Ozark Forest Ecosystem Project (MOFEP), a 100-year experiment designed to study the effects of even-age and uneven-age management on wildlife. We spot-mapped territories of 15 species in 228 stands for 5 years before treatment and 14 years after treatment to assess the effects of stand-level silvicultural treatments (clearcut, select cut, thin, and no-harvest) applied within even-age, uneven-age, or no-harvest (control) management sites and year on avian territory density. We used 2 a priori contrasts to compare pre-treatment bird densities with densities during early (3-5 yr) and late (12-14 yr) post-treatment periods. The interaction of silvicultural treatment and year had significant effects on the densities of all 15 species. Densities of hooded warbler (Setophaga citrina), indigo bunting (Passerina cyanea), prairie warbler (Setophaga discolor), and yellow-breasted chat (Icteria virens) increased significantly 3-5 years post-treatment with the greatest changes in clearcuts, but densities 12-14 years post-treatment did not differ from pre-treatment densities. Densities of Acadian flycatcher (Empidonax virescens), wood thrush (Hylocichla mustelina), and especially ovenbird (Seiurus aurocapilla) had significant decreases in clearcut stands after treatment and lesser decreases in select cut or thin stands post-treatment. Densities of black-and-white warbler (Mniotilta varia), eastern wood-pewee (Contopus virens), and Kentucky warbler (Geothlypis formosa) increased in clearcut, thin, and select cut stands, but these increases were short-lived and sporadic by year after treatment. Densities of Acadian flycatcher and ovenbird remained lower in clearcut stands than no-harvest stands 13 years post-treatment. The results of this manipulative experiment were mostly consistent with our predictions of bird response to common silvicultural treatments in these forests. Managers can use these species-specific responses to silvicultural treatment to guide management decisions for target species or to balance management practices in a landscape to meet the needs of multiple species.

Knowledge of the general reactivity and chemistry of this compound is helpful for a better understanding of cellulose aging and yellowing as well as bleaching of cellulosic materials - processes that also have considerable economic importance. This paper reviews the reactions reported for 2,5-dihydroxyacetophenone from the viewpoints of both synthesis and general reactivity. The compound exhibits a rich chemistry due to the superposition of the hydroquinone structure and the 2-hydroxyacetophenone structure with its alpha-hydroxy ortho-quinone methide tautomer. The 1-acetyl group exhibits high reactivity attributed to resonance of the carbonyl group with the pi-electrons of the benzene ring and proton donation to the carbonyl group from the adjacent 2-hydroxy group. One of the prominent conversion paths for DHAP are aldol-type reactions that have been applied for the synthesis of a multitude of flavonoids. Other reaction pathways are nucleophilic substitution on the carbonyl group mainly with amines, electrophilic addition to the benzene ring, and oxidation into the corresponding benzoquinone. There are also quite a few reports of selective derivatization of the 5-hydroxy group of DHAP that has a higher reactivity than its 2-OH counterpart that is engaged in tight hydrogen bonding with the acetyl carbonyl moiety and thus largely blocked in esterifications and similar derivatizations.

TI Plant Macro- and Micronutrient Dynamics in a Biochar-Amended Wetland Muck SO WATER AIR AND SOIL POLLUTION LA English DT Article DE Biochar; Wetlands; Soluble nutrients; Leaching ID MANAGEMENT-PRACTICES; ALTERED WETLAND; SOIL; AMENDMENT; POROSITY AB Biochar is an organic carbon (OC) and plant nutrient-rich substance that may be an ideal amendment for bolstering soil organic matter and nutrient contents. Two biochars were produced by pyrolysis at 350 degrees C from pine chips (Pinus taeda) and swine manure solids (Sus scrofa domesticus). The biochar total elemental composition was quantified using inductively coupled plasma spectrometer and their surface chemical composition examined using a combination of scanning electron microscopy (SEM) and electron dispersive spectroscopy (EDS). The biochars were mixed into triplicate pots containing Lauderhill muck (Euic, hyperthermic Lithic Haplosaprist) at 0, 2.5, 5, and 10 % (dry mass). Four simulated water infiltration events were conducted during the 124-day incubation to assess the potential alteration in the leaching potential of soluble soil nutrients. At termination, the muck's fertility characteristics were assessed, and dissolved cations were measured in water leachates. Neither biochars significantly increased the muck's OC contents. Swine manure biochar contained higher K, Mg, Na, and P concentrations, and these differences were observable in SEM and EDS as differing amounts of surface-precipitated Mg and K salts. Correspondingly, swine manure biochar at all three applications rates significantly increased Mehlich 1-s K, P, Mg, and Na concentrations. Pine chip biochar only improved the Mehlich 1-extractable K concentration but did reduce soluble P concentrations. Water leachates from swine manure biochar treated wetland soil contained significantly higher soluble P concentrations that could create water quality issue in downstream ecosystems. C1 [Novak, J.

APH is a highly competitive sector with a strong emphasis on innovation and, albeit with country to country variations, on scientific research. Proteomics (the study of all proteins present in a given tissue or fluid - i.e. the proteome) has an enormous potential when applied to APH. Nevertheless, for a variety of reasons and in contrast to disciplines such as plant sciences or human biomedicine, such potential is only now being tapped. To counter such limited usage, 6 years ago we created a consortium dedicated to the applications of Proteomics to APH, specifically in the form of a Cooperation in Science and Technology (COST) Action, termed FA1002 - Proteomics in Farm Animals: www.cost-faproteomics.org. In 4 years, the consortium quickly enlarged to a total of 31 countries in Europe, as well as Israel, Argentina, Australia and New Zealand. This article has a triple purpose. First, we aim to provide clear examples on the applications and benefits of the use of proteomics in all aspects related to APH. Second, we provide insights and possibilities on the new trends and objectives for APH proteomics applications and technologies for the years to come. Finally, we provide an overview and balance of the major activities and accomplishments of the COST Action on Farm Animal Proteomics. These include activities such as the organization of seminars, workshops and major scientific conferences, organization of summer schools, financing Short-Term Scientific Missions (STSMs) and the generation of scientific literature. Overall, the Action has attained all of the proposed objectives and has made considerable difference by putting proteomics on the global map for animal and veterinary researchers in general and by contributing significantly to reduce the East-West and North-South gaps existing in the European farm animal research. Future activities of significance in the field of scientific research, involving members of the action, as well as others, will likely be established in the future. C1 [Almeida, A.

Six Holstein steers (360 +/- 22 kg) were maintained at 21 degrees C and fed three different energy intakes within a replicated 3 x 3 Latin square design with 21-day periods. Steers were fed alfalfa cubes to provide 1.0, 1.5 and 2.0 x NEm during 19 days of each experimental period. Steers were placed in individual metabolism stalls fitted with indirect calorimetry head-boxes on day 20 of each experimental period (FED steers) and fed their normal meal. On day 21 of each period the reticulorumen was emptied, washed and refilled with ruminal buffer (NaCl = 96; NaHCO3 = 24; KHCO3 = 30; K2HPO4 = 2; CaCl2 = 1.5; MgCl2 = 1.5 mmol/kg of buffer) aerated with 75% N-2 and 25% CO2 before introduction to the rumen (steers were not fed; WASHED steers). Each gas exchange was measured over 24 h. HP for 1.0, 1.5 and 2.0 x NEm were 479, 597 and 714 kJ/day kg(0.75) (s.e.m. = 16), respectively. The plateau RQ was 0.756, 0.824 and 0.860 for the 1.0, 1.5 and 2.0 x NEm intakes for the FED steers, respectively. After rumen washing, fasting HP was 331, 359 and 400 kJ/day kg(0.75) (s.e.m. = 13) for 1.0, 1.5, and 2.0 x NEm intakes before fasting, respectively. The RQ for WASHED rumen steers was 0.717, 0.710 and 0.719, respectively. Cortisol and beta-hydroxybutyrate concentrations in WASHED rumen steers did not exceed threshold levels for severe energy deficit and stress as can be induced from prolonged fasting. This study demonstrates that a fasting state can be emulated using the washed rumen technique, minimizing the time required as opposed to traditional fasting methodologies, without causing a severe energy deficit C1 [Kim, D.

TI Host specificity testing and examination for plant pathogens reveals that the gall-inducing psyllid Calophya latiforceps is safe to release for biological control of Brazilian peppertree SO ENTOMOLOGIA EXPERIMENTALIS ET APPLICATA LA English DT Article DE Anacardiaceae; Calophyidae; Candidatus Liberibacter; Hemiptera; invasive plant; leaf gall; plant virus; Schinus terebinthifolia ID SCHINUS-TEREBINTHIFOLIUS ANACARDIACEAE; CANDIDATUS LIBERIBACTER SOLANACEARUM; REAL-TIME PCR; HEMIPTERA PSYLLOIDEA; LICE HEMIPTERA; FLORIDA; DISEASES; POTATO; HERBIVORES; INDUCTION AB Brazilian peppertree, Schinus terebinthifolia Raddi (Anacardiaceae), is one of the worst upland exotic weeds in Florida, USA. Foreign exploration for natural enemies led to the discovery of a pit-galling psyllid, Calophya latiforceps Burckhardt (Hemiptera: Calophyidae), in the state of Bahia, Brazil, in 2010. Crawlers of C.latiforceps stimulate the formation of galls on the leaves of S.terebinthifolia resulting in leaf discoloration and in some cases leaf abscission. To determine whether C.latiforceps is a safe candidate for biological control of S.terebinthifolia, host specificity and the presence of selected plant pathogens were examined. Adult oviposition, gall formation, and adult survival of C.latiforceps were examined on 89 plant species under no-choice and choice conditions. We found that C.latiforceps laid eggs on plants in seven families; however, crawlers stimulated gall formation and completed development to adult only on S.terebinthifolia. All crawlers on non-target plants died, likely due to starvation caused either by the absence of a feeding stimulus or by a hypersensitive plant response. Under no-choice conditions, 10% of adults lived for 19days on the target weed, but adult survival was reduced to <3days on non-target plants. Choice testing revealed that females preferred to oviposit on S.terebinthifolia compared to non-target plants. Molecular methods and indicator host inoculations did not detect the presence of Candidatus Liberibacter solanacearum', Ca.L. asiaticus', Ca.L. americanus', Ca.L. africanus', or plant viruses in adult C.latiforceps. We conclude that releasing C.latiforceps in the USA will have extremely low risk to non-target plants, and provides another tool for the management of S.terebinthifolia.

However, there is concern that certain standardized arthropod collection methods, such as sweep netting, might lead to high incidences of protein transfer from field-marked to unmarked arthropods during sample collection and sample handling. Native arthropods were collected in sweep nets from a field of alfalfa, Medicago sativa L. (Fabaceae). The nets also contained 10 egg white-, 10 bovine milk-, 10 soy milk-, and 10 water (control)-marked Hippodamia convergens Guerin-Meneville (Coleoptera: Coccinellidae) that were visually distinguishable by a yellow, white, green, and blue dot, respectively. The plant debris and arthropods from each sweep net collection were then placed into either a paper or a plastic bag andfrozen for storage. The contents of each sweep net sample were thawed and the color-coded H.convergens and field-collected arthropods were examined for the presence of each protein by an egg white (albumin), bovine milk (casein), and soy milk (soy trypsin) enzyme-linked immunosorbent assay (ELISA). Data revealed that only 0.67, 0.81, and 0% of the field-collected unmarked arthropods acquired an egg white, bovine milk, and soy milk mark, respectively. ELISA results also showed that all the egg white-marked H.convergens retained their mark, but 22.1% of the bovine milk-marked and 5.1% of the soy milk-marked H.convergens (color-coded beetles) lost their mark during the collection and sample handling processes.

Solid adsorbents require large solvent rinses and glass capillaries can be difficult to maneuver for the collection of volatiles from small or hard-to-reach odor sources. A gas chromatograph (GC) column (DB-1), an open-tube glass capillary, and a SuperQ((R))-containing capillary were compared for their collection efficiencies from rubber septa and live calling insects. All three traps captured similar ratios of test compounds from septa at airflows >10ml per min. Eluting analytes from a packed adsorbent, SuperQ, required at least 30x more solvent than was required to collect all the pheromone from the open-tube glass capillaries, and the GC column enjoyed an additional three-fold reduced solvent volume compared to the glass capillary. Thus, analytes could be eluted from the GC-column trap and directly analyzed on GC without solvent evaporation. We placed glass wool plugs' in both GC columns and glass capillaries and found no volatiles in these plugs, indicating that breakthrough did not occur during 1-h collections at 25ml per min. We demonstrate here that at ambient laboratory temperatures, a DB-1 GC column effectively collects Oriental fruit moth sex pheromone volatiles from a rubber septum and live pheromone-releasing moths. Release ratios of pheromone from rubber septa are consistent with earlier reports from static air systems, whereas the release ratio of the (Z)-8-dodecenyl alcohol (Z8-12:OH) from female Grapholita molesta Busck (Lepidoptera: Tortricidae) differed from published results and is likely due to different collection methods or moth-strain origin.

E. coli O157 was present in 26% (68/2654) of faecal, 15% (3/204) of water and 11% (1/93) of sediment samples collected on eight ranches over 2.5 years. Five (625%) ranches were positive at least once during the study. The odds of detecting E. coli O157 in faecal samples was higher during periods of higher maximum soil temperature, higher maximum relative humidity, and larger herd sizes, but decreased as wind speed increased. Molecular subtyping of isolates from cattle faeces and streams/sediments suggested minimal movement of strains between ranches. The findings suggest that E. coli O157 prevalence is relatively low on cow-calf ranches in this region, spatially constrained, but may vary by weather conditions and herd size. C1 [Benjamin, L.

TI Performance, digestion, nitrogen balance, and emission of manure ammonia, enteric methane, and carbon dioxide in lactating cows fed diets with varying alfalfa silage-to-corn silage ratios SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE greenhouse gas; rumen fermentation; nitrogen utilization; forage; soybean ID MILK UREA NITROGEN; DAIRY-COWS; CONCENTRATE RATIO; BEEF HEIFERS; PROTEIN; DIGESTIBILITY; FORAGES; STARCH; FERMENTABILITY; MANIPULATION AB Two trials were conducted simultaneously to study the effects of varying alfalfa silage (AS) to corn silage (CS) ratio in diets formulated to avoid excess protein or starch on lactating dairy cow performance, digestibility, ruminal parameters, N balance, manure production and composition, and gaseous emissions [carbon dioxide (CO2), methane (CH4), and ammonia-N (NH3-N)]. In trial 1 all measurements, except gas emissions, were conducted on 8 rumen-cannulated cows in replicated 4 x 4 Latin squares. In trial 2, performance and emissions were measured on 16 cows randomly assigned to 1 of 4 air-flow controlled chambers in a 4 x 4 Latin square. Dietary treatments were fed as total mixed rations with forage-to-concentrate ratio of 55:45 [dietary dry matter (DM) basis] and AS:CS ratios of 20:80, 40:60, 60:40, and 80:20 (forage DM basis). Measurements were conducted the last 3 d of each 21-d period. Treatments did not affect DM intake, DM digestibility, and milk/DM intake. However, responses were quadratic for fat-andprotein-corrected milk, fat, and protein production, which reached predicted maxima for AS:CS ratio of 50:50, 49:51, and 34:66, respectively. Nitrogen use efficiency (milk N/N intake) decreased from 31 to 24 g/100 g as AS:CS ratio increased from 20:80 to 80:20. Treatments did not alter NH3-N/milk-N but tended to have a quadratic effect on daily NH3-N emission. Treatments had a quadratic effect on daily CH4 emission, which was high compared with current literature; they influenced CH4 emission per unit of neutral detergent fiber (NDF) intake and tended to influence CO2/NDF intake. Ruminal acetate-to-propionate ratio and total-tract NDF digestibility increased linearly with increasing AS:CS ratio. In addition, as AS:CS ratio increased from 20:80 to 80:20, NDF digested increased linearly from 2.16 to 3.24 kg/d, but CH4/digested NDF decreased linearly from 270 to 190 g/kg. These 2 counterbalancing effects likely contributed to the observed quadratic response in daily CH4 emission, which may have been influenced also by increasing starch with increasing CS in the diet as reflected by the increased ruminal propionate molar proportion. Overall, production performances were greatest for the intermediate AS:CS ratios (40:60 and 60:40), but daily excretion of urine, manure, fecal N, urinary urea N, and urinary N decreased with increasing proportion of CS in the diet, whereas daily CH4 emision was reduced for the 2 extreme AS:CS ratios (20:80 and 80:20). However, the proportion of AS and CS in the diet did not affect CH4/fat-and-protein corrected milk. C1 [Arndt, C.; Aguerre, M. J.; Wattiaux, M.

Eight multiparous and 8 primiparous Jersey cows averaging 135 +/- 49 d in milk and 386 +/- 61 kg of body weight in the beginning of the study were randomly assigned to 4 replicated 4 x 4 Latin squares with a 2 x 2 factorial arrangement of treatments. Each period lasted 19 d with 14 d for diet adaptation and 5 d for data and sample collection. Cows were fed diets composed of mixedmostly grass hay plus 1 of the following 4 concentrate blends: (1) corn meal plus a protein mix containing soybean meal and sunflower meal; (2) corn meal plus flaxseed meal; (3) liquid molasses plus a protein mix containing soybean meal and sunflower meal; or (4) liquid molasses plus flaxseed meal. Data were analyzed for main effects of NSC and RDP supplements, and the NSC x RDP supplement interactions. Significant NSC x RDP supplement interactions were observed for milk urea N, milk N efficiency, and the sums of milk saturated, monounsaturated, and polyunsaturated fatty acids. No effect of NSC supplements was observed for nutrient intake and milk yield. However, 4% fat-corrected milk (-0.70 kg/d) and energy-corrected milk (-0.60 kg/d) were significantly reduced in cows fed liquid molasses due to a trend to decreased concentration of milk fat (-0.17%). Diets with liquid molasses resulted in increased (+35%) concentration and yield of milk enterolactone, indicating that this mammalian lignan can be modulated by supplements with different NSC profiles. Overall, NSC and RDP supplements pro- foundly changed the milk fatty acid profile, likely because of differences in fatty acids intake, Delta(9)-desaturase indices, and ruminal biohydrogenation pathways. Feeding liquid molasses significantly reduced plasma urea N (-1.2 mg/dL), urinary N excretion (-20 g/d), and N digestibility (-3.2 percentage units) Flaxseed meal significantly reduced yields of milk (-1.3 kg/d), milk fat (-90 g/d), and milk lactose (-60 g/d), but significantly increased the concentration and yield of milk enterolactone. Further research is needed to elucidate the negative responses of flaxseed meal on yields of milk and milk components. C1 [Brito, A. F.; Pereira, A. B.

Formative research was conducted with nutritionists during the development of the web-based questionnaire. The suggestions and insights obtained were used to design a tool to monitor schoolchildren's food consumption based on the concept of healthy and unhealthy food indicators. The present study aimed to report the focus group discussions conducted with nutritionists concerning the CAAFE questionnaire. MethodsFocus group discussions were conducted using a semi-structured questionnaire, and these were then analysed thematically. ResultsTwenty-four nutritionists participated (four focus groups; average per group: six people); the majority (n=22) had experience with 7-10-year-old children. Four themes emerged: (i) healthy and unhealthy food indicators; (ii) suggestions for the online instrument; (iii) potential applications; and (iv) challenges for its construction. ConclusionsComments made by nutritionists enabled the construction of an instrument that is able to answer questions related to food consumption in schools and at home. C1 [Davies, V.

TI Validation of a web-based questionnaire to assess the dietary intake of Brazilian children aged 7-10 years SO JOURNAL OF HUMAN NUTRITION AND DIETETICS LA English DT Article DE intrusions; matches; omissions; online; questionnaire ID ADOLESCENTS; TECHNOLOGIES; PREVALENCE; SOFTWARE; OBESITY; FRUIT AB BackgroundThe Food Intake and Physical Activity of School Children (CAAFE) comprises an online questionnaire to self-report diet and physical activity of Brazilian schoolchildren. BackgroundThe present study aimed to assess the validity (matches, omissions and intrusions) and moderating factors of the CAAFE. MethodsDirect observation was made of foods consumed (five public schools) and child self-reporting on the CAAFE. Additional data included school grade, gender, body mass index, completion of food diary, socioeconomic status and access to computer. Data were analysed using regression. ResultsIn total, 602 children participated in the study [mean (SD) age 9.5(1.24)years; 53.6% boys]. On average, there were 43% matches, 29% intrusions and 28% omissions. Matches doubled in third grade compared to the second grade (P=0.004); matches almost tripled for afternoon snack compared to morning snack (P<0.001); and matches were 69% higher for children with access to a computer at home (P<0.01). Intrusions decreased by almost one-half in fifth compared to fourth grades (P=0.004). Omissions declined significantly in the third and fourth grades but increased in the fifth grade. Omissions were 47% lower for children in the highest income and lower among children who completed the food diary. No differences were found for gender or body mass index. ConclusionsChildren older than 8years old, who owned a computer and completed a food diary, performed better in the CAAFE. A high incidence of disagreement was found in relation to the schools and the type of meal. Overall matches (43%), intrusions (29%) and omissions (28%) indicate that further studies are required to improve the validity of the CAAFE. C1 [Davies, V.

TI Method formonitoring deletions in the aflatoxin biosynthesis gene cluster of Aspergillus flavus with multiplex PCR SO LETTERS IN APPLIED MICROBIOLOGY LA English DT Article DE aflatoxin; Aspergillus flavus; biocontrol; cyclopiazonic acid; multiplex PCR; subtelomere stability ID BIOLOGICAL-CONTROL; COST-EFFECTIVENESS; CONTAMINATION; COTTONSEED; SEQUENCE; STRAINS; ORYZAE; HEALTH AB The report presents a rapid, inexpensive and simple method for monitoring indels with influence on aflatoxin biosynthesis within Aspergillus flavus populations. PCR primers were developed for 32 markers spaced approximately every 5kb from 20kb proximal to the aflatoxin biosynthesis gene cluster to the telomere repeat. This region includes gene clusters required for biosynthesis of aflatoxins and cyclopiazonic acid; the resulting data were named cluster amplification patterns (CAPs). CAP markers are amplified in four multiplex PCRs, greatly reducing the cost and time to monitor indels within this region across populations. The method also provides a practical tool for characterizing intraspecific variability in A.flavus not captured with other methods. Significance and Impact of the StudyAflatoxins, potent naturally-occurring carcinogens, cause significant agricultural problems. The most effective method for preventing contamination of crops with aflatoxins is through use of atoxigenic strains of Aspergillus flavus to alter the population structure of this species and reduce incidences of aflatoxin producers. Cluster amplification pattern (CAP) is a rapid multiplex PCR method for identifying and monitoring indels associated with atoxigenicity in A.flavus. Compared to previous techniques, the reported method allows for increased resolution, reduced cost, and greater speed in monitoring the stability of atoxigenic strains, incidences of indel mediated atoxigenicity and the structure of A.flavus populations.

TI Transcriptome Analysis of a Ustilago maydis ust1 Deletion Mutant Uncovers Involvement of Laccase and Polyketide Synthase Genes in Spore Development SO MOLECULAR PLANT-MICROBE INTERACTIONS LA English DT Article ID PATHOGEN USTILAGO-MAYDIS; ASPERGILLUS-FUMIGATUS; MELANIN BIOSYNTHESIS; TELIOSPORE FORMATION; CRYPTOCOCCUS-NEOFORMANS; BINDING-PROTEIN; MAIZE; DIMORPHISM; CLUSTER; VIRULENCE AB Ustilago maydis, causal agent of corn smut disease, is a dimorphic fungus alternating between a saprobic budding haploid and an obligate pathogenic filamentous dikaryon. Maize responds to U. maydis colonization by producing tumorous structures, and only within these does the fungus sporulate, producing melanized sexual teliospores. Previously we identified Ust1, an APSES (Asmlp, Phdlp, Sok2p, Efg1p, and StuAp) transcription factor, whose deletion led to filamentous haploid growth and the production of highly pigmented teliospore-like structures in culture. In this study, we analyzed the transcriptome of a ust1 deletion mutant and functionally characterized two highly upregulated genes with potential roles in melanin biosynthesis: um05361, encoding a putative laccase (lac1), and um06414, encoding a polyketide synthase (pks1). The Delta lac1 mutant strains showed dramatically reduced virulence on maize seedlings and fewer, less-pigmented teliospores in adult plants. The Delta pks1 mutant was unaffected in seedling virulence but adult plant tumors generated hyaline, nonmelanized teliospores. Thus, whereas pks1 appeared to be restricted to the synthesis of melanin, lac1 showed a broader role in virulence. In conclusion, the ust1 deletion mutant provided an in vitro model for sporulation in U. maydis, and functional analysis supports the efficacy of this in vitro mutant analysis for identification of genes involved in in planta teliosporogenesis.

Previously, we showed that Ust1, the first APSES (Asmlp, Phdlp, Sok2p, Efg1p, and StuAp) transcription factor functionally characterized in the phylum Basidiomycota, controlled morphogenesis and virulence in this species. Here, we further analyzed Ust1 function using multiple experimental approaches and determined that i) Ust1 activity was able to partially reverse stuA-conidiophore defects in Aspergillus nidulans; ii) in U. maydis, normal development and virulence were strongly dependent on precise induction or repression of Ust1 activity; iii) consistent with its role as a transcription factor regulating multiple processes, Ust1 accumulated in the nucleus at various stages of the life cycle; iv) however, it was undetectable at specific stages of pathogenic growth, indicating that Ust1 repression is part of normal development in planta; v) StuA response elements upstream of the ust1 open reading frame exhibited affinity for U. maydis DNA-binding proteins; vi) however, loss of regulated ust1 transcription had minor phenotypic effects; and vii) Ust1 was subject to post-translational phosphorylation but is not a target of cAMP signaling. Thus, the broad functional conservation between Ust1 and Ascomycota APSES proteins does not extend to the mechanisms regulating their activity.

Currently, basic information is lacking concerning the distribution, functional characteristics, and evolution of ARK1 binding in the Populus genome. Here, we used chromatin immunoprecipitation sequencing (ChIP-seq) technology to identify ARK1 binding loci genome-wide in Populus. Computational analyses evaluated the distribution of ARK1 binding loci, the function of genes associated with bound loci, the effect of ARK1 binding on transcript levels, and evolutionary conservation of ARK1 binding loci. ARK1 binds to thousands of loci which are highly enriched proximal to the transcriptional start sites of genes of diverse functions. ARK1 target genes are significantly enriched in paralogs derived from the whole-genome salicoid duplication event. Both ARK1 and a maize (Zea mays) homolog, KNOTTED1, preferentially target evolutionarily conserved genes. However, only a small portion of ARK1 target genes are significantly differentially expressed in an ARK1 over-expression mutant. This study describes the functional characteristics and evolution of DNA binding by a transcription factor in an undomesticated tree, revealing complexities similar to those shown for transcription factors in model animal species.

Multistage validation had been used in model creation by incorporating previously validated submodels for infection, latent period duration, sporulation, fungicide effects, and plant growth. Validation of the complete model was by comparison of model output with observed disease severities in 35 epidemics at nine location-years in the Pacific Northwest of the United States. We judge the model acceptable for its purposes, based on several tests. Graphs of modeled disease progress were generally congruent with plotted disease severity observations. There was negligible average bias in the 570 modeled-versus-observed comparisons across all data, although there was large variance in size of the deviances. Modeled severities were accurate in >80% of the comparisons, where accuracy is defined as the modeled value being within twice the 95% confidence interval of the observed value, within +/- 1 day of the observation date. An interactive website was created to produce disease estimates by running STEMRUST_G with user-supplied disease scouting information and automated daily weather data inputs from field sites. The model and decision aid supplement disease managers' information by estimating the level of latent (invisible) and expressed disease since the last scouting observation, given season-long weather conditions up to the present, and it estimates effects of fungicides on epidemic development. In additional large-plot experiments conducted in grower fields, the decision aid produced disease management outcomes (management cost and seed yield) as good as or better than the growers' standard practice. In future, STEMRUST_G could be modified to create similar models and decision aids for stem rust of wheat and barley, after additional experiments to determine appropriate parameters for the disease in these small-grain hosts.

The model has a daily time step and is driven by weather data and an initial input of disease severity from field observation. Key aspects of plant growth are modeled. Disease severity is modeled as rust population growth, where individuals are pathogen colonies (pustules) grouped in cohorts defined by date of initiation and plant part infected. Infections due to either aerial spread or within-plant contact spread are modeled. Pathogen cohorts progress through life stages that are modeled as disease cycle components (colony establishment, latent period, infectious period, and sporulation) affected by daily weather variables, plant growth, and fungicide application. Fungicide effects on disease cycle components are modeled for two commonly used active ingredients, applied preinfection or postinfection. Previously validated submodels for certain disease cycle components formed the framework for integrating additional processes, and the complete model was calibrated with field data from 10 stem rust epidemics. Discrepancies between modeled outcomes and the calibration data (log(10)[modeled] - log(10)[observed]) had a mean near zero but considerable variance, with 1 standard deviation = 0.5 log(10) units (3.2-fold). It appears that a large proportion of the modeling error variance may be due to variability in field observations of disease severity. An action threshold for fungicide application was derived empirically, using a constructed weather input file favorable for disease development. The action threshold is a negative threshold, representing a level of disease (latent plus visible) below which damaging levels of disease are unable to develop before the yield-critical crop stage. The model is in the public domain and available on the Internet. C1 [Pfender, W. F.] ARS, USDA, Natl Forage Seed Prod Res Ctr, Corvallis, OR 97331 USA.

TI Frequency of Verticillium Species in Commercial Spinach Fields and Transmission of V. dahliae from Spinach to Subsequent Lettuce Crops SO PHYTOPATHOLOGY LA English DT Article ID LACTUCA-SATIVA; PLANT-DISEASE; WILT; SEED; PATHOGEN; SOIL; WHEAT; COLONIZATION; EPIDEMIOLOGY; RESISTANCE AB Verticillium wilt caused by V. dahliae is a devastating disease of lettuce in California (CA). The disease is currently restricted to a small geographic area in central coastal CA, even though cropping patterns in other coastal lettuce production regions in the state are similar. Infested spinach seed has been implicated in the introduction of V. dahliae into lettuce fields but direct evidence linking this inoculum to wilt epidemics in lettuce is lacking. In this study, 100 commercial spinach fields in four coastal CA counties were surveyed to evaluate the frequency of Verticillium species recovered from spinach seedlings and the area under spinach production in each county was assessed. Regardless of the county, V. isaacii was the most frequently isolated species from spinach followed by V. dahliae and, less frequently, V. klebahnii. The frequency of recovery of Verticillium species was unrelated to the occurrence of Verticillium wilt on lettuce in the four counties but was related to the area under spinach production in individual counties. The transmission of V. dahliae from infested spinach seeds to lettuce was investigated in microplots. Verticillium wilt developed on lettuce following two or three plantings of Verticillium-infested spinach, in independent experiments. The pathogen recovered from the infected lettuce from microplots was confirmed as V. dahliae by polymerase chain reaction assays. In a greenhouse study, transmission of a green fluorescence protein-tagged mutant strain of V. dahliae from spinach to lettuce roots was demonstrated, after two cycles of incorporation of infected spinach residue into the soil. This study presents conclusive evidence that V. dahliae introduced via spinach seed can cause Verticillium wilt in lettuce. C1 [Short, D. P. G.; Gurung, S.; Subbarao, K.

TI Evidence for Systemic Infection by Puccinia horiana, Causal Agent of Chrysanthemum White Rust, in Chrysanthemum SO PHYTOPATHOLOGY LA English DT Article ID DISEASES; FUNGUS; ELM AB Puccinia horiana, causal agent of the disease commonly known as chrysanthemum white rust (CWR), is a quarantine-significant fungal pathogen of chrysanthemum in the United States and indigenous to Asia. The pathogen was believed to have been eradicated in the United States but recently reappeared on several occasions in northeastern United States. The objective of the study presented here was to determine whether P. horiana could systemically infect chrysanthemum plants, thus providing a means of survival through winters. Scanning and transmission electron microscopy revealed the development of P. horiana on the surface and within leaves, stems, or crowns of inoculated chrysanthemum plants artificially exposed to northeastern U.S. winter temperatures. P. horiana penetrated leaves directly through the cuticle and then colonized the mesophyll tissue both inter-and intracellularly. An electron-dense material formed at the interface between fungal and host mesophyll cells, suggesting that the pathogen adhered to the plant cells. P. horiana appeared to penetrate mesophyll cell walls by enzymatic digestion, as indicated by the absence of deformation lines in host cell walls at penetration sites. The fungus was common in vascular tissue within the infected crown, often nearly replacing the entire contents of tracheid cell walls. P. horiana frequently passed from one tracheid cell to an adjacent tracheid cell by penetration either through pit pairs or nonpitted areas of the cell walls. Individual, presumed, fungal cells in mature tracheid cells of the crown and stems arising from infected crowns suggested that the pathogen might have been moving at least partially by means of the transpiration stream. The demonstration that chrysanthemum plants can be systemically infected by P. horiana suggests that additional disease control measures are required to effectively control CWR. C1 [Bonde, M.

INVASION AB Fire has profound effects on ecosystem properties, but few studies have addressed the effect of repeated burns on soil nutrients, and none have been conducted in cold desert ecosystems where invasion by exotic annual grasses is resulting in greater fire frequency. In a 5 year study, we examined effects of repeated burning, litter removal, and post-fire seeding on carbon (C) and nitrogen (N) contents in soils, litter, and vegetation in a cheatgrass-dominated Wyoming big sagebrush ecological type. We developed a multivariate model to identify potential mechanisms influencing treatment effects and examine the influence of environmental factors such as precipitation and temperature. We found that repeated burning had strong negative effects on litter C and N contents, but did not reduce soil nutrients or vegetation C and N contents, likely due to cool fire temperatures. There were few effects of litter removal or post-fire seeding. Instead, precipitation and temperature interacted with burning and had the strongest influences on soil N and vegetation C and N contents over time. Management strategies aimed at decreasing litter and seed banks and increasing competitive interactions may be more effective at reducing cheatgrass success than approaches for reducing soil nutrients.

Our aim was to determine if greater soil N in native prairies interseeded with alfalfa would increase trace gas emissions of nitrous oxide (N2O) and methane (CH4). A chronosequence study to investigate interseeded alfalfa on the fluxes of N2O and CH4 was undertaken on three prairie sites. At each site, native grasslands interseeded with alfalfa for 38, 16 and 5 years, along with adjacent native grassland controls and native grasslands fertilized with a one-time addition of N fertilizer, were measured for NO2 and CH4 using static chambers. Across interseeding years there were few significant differences between the three treatments (Native, Alfalfa, Fertilized). Despite increased soil N, the interseeded treatment released no more N2O than native grasslands. Methane uptake was generally greatest on interseeded grasslands and least on fertilized grasslands. Our results suggest that while alfalfa can increase soil N and improve productivity, it did not increase trace gas production relative to native grasslands. This is a win-win situation for ranchers wishing to increase soil fertility and thus their overall productivity and forage quality without increasing trace gas emissions. C1 [Ingram, L.

Kenaf is a bast fiber plant where the surface stem skin provides bast fibers whose strength-to-weight ratio competes with glass fiber. The higher volume product of the kenaf core is an under-investigated area in composite applications. The naturally porous structure of kenaf-core provides a novel reinforcement particle. In this work, foams of rigid polyurethane with 5, 10, and 15% kenaf-core were formed. To date efforts at using it as a reinforcement have proven largely unsuccessful. This was mirrored in this effort when free expansion of the foam was utilized. However, introducing constraint during foaming resulted in reinforcement. The environmental scanning electron microscopy is used in conjunction with in-situ microCT compression to capture the change in void fractions before and after deformation. The results show that free foaming resulted in poor reinforcement while a constrained expansion on the foam increased the reinforcement potential of the kenaf core. POLYM. ENG.

It has been presumed that the major functional role for oxidation-labile Met residues is to protect proteins/cells from oxidative stress. However, Met oxidation has been established as a key mechanism for direct regulation of a wide range of protein functions and cellular processes. Furthermore, recent reports suggest an interaction between Met oxidation and O-phosphorylation. Such interactions are a potentially direct interface between redox sensing and signaling, and cellular protein kinase/phosphatase-based signaling. Herein, we describe the current state of Met oxidation research, provide some mechanistic insight into crosstalk between these two major posttranslational modifications, and consider the evolutionary significance and regulatory potential of this crosstalk.

This review reports on recent findings that bolus is advantageous compared to continuous feeding in supporting optimal protein anabolism. Recent findings Whether bolus or continuous feeding is more beneficial has been controversial, largely due to limitations inherent in clinical studies, such as the presence of confounding variables and the inability to use invasive approaches. Recent studies using the piglet as a model of the human neonate showed that, compared to continuous feeding, bolus feeding enhances protein synthesis and promotes greater protein deposition. The increase in protein synthesis occurs in muscles of varying fiber type and in visceral tissues whereas muscle protein degradation is largely insensitive to feeding pattern. This higher protein synthesis rate is enabled by the rapid and profound increases in circulating amino acids and insulin that occur following a bolus feed, which activate the intracellular signaling pathways leading to mRNA translation. Summary Recent findings indicate that bolus feeding enhances protein synthesis more than continuous feeding and promotes greater protein anabolism. The difference in response is attributable to the pulsatile pattern of amino acid-induced and insulin-induced translation initiation induced only by bolus feeding.

Merr.) is a major source of plant protein for humans and livestock. Deficiency of sulfur-containing amino acids (cysteine and methionine) in soybean protein is a main limitation of soybean meal as an animal feed ingredient. The objectives of this study were to identify and validate quantitative trait loci (QTLs) associated with cysteine and methionine contents in two recombinant inbred line (RIL) populations, and to analyze the genetic effects of individual QTLs and QTL combinations in soybean. Both the mapping population of SD02-4-59 x A02-381100 and validation population of SD02-911 x SD00-1501 were evaluated for cysteine and methionine contents in multiple environments. Correlation analysis indicated that there was a highly positive correlation between cysteine and methionine contents. Significant positive correlations were also observed between the sulfur-containing amino acid contents and protein content. In the mapping population, eight QTLs for both cysteine and methionine contents were consistently detected in any individual environment and the average data over all three environments. Three of these QTLs were confirmed in the validation population. A comparison with the previous studies indicated that most of the genomic regions linked to the QTLs for the sulfur-containing amino acids were also associated with protein content. Cumulative effects of multiple QTLs for the traits were significant in both populations. This information should be useful for the improvement of the levels of protein and amino acids in soybean seeds.

LocationIndia (Kashmir) and Switzerland (native range) and Australia and USA (Hawaii, Montana and Oregon) (non-native range). MethodsWe measured population characteristics (density of flowering individuals, population size), plant traits (plant height, number of flowering branches) and seed germination for 50 populations of V. thapsus growing along elevational gradients in six mountain regions around the world (two in the native range, and four in the non-native range). We fitted linear regression models to determine the relationship of plant and population level performance variables to range, region, climate and probability of occurrence from a global niche model. ResultsPlant height, number of flowering branches and population density of V. thapsus did not differ consistently between the native and non-native ranges, but the area covered by populations in the non-native range was on average two orders of magnitude larger than the area of native populations. Within and among regions, individual plant performance traits responded variably to precipitation and mean annual temperature, depending on the climatic range of the observed populations; however, performance was greater for populations that had a greater modelled probability of occurrence. Seed germination under controlled conditions was highest between 20 and 35 degrees C and consistent across populations, although germination at low temperatures was substantially higher for native populations from Kashmir. Main conclusionsThe introduction of V. thapsus to its non-native range is not associated with consistent increases in plant performance. Instead, plant performance is more strongly influenced by position within the climate niche of the species, position along environmental gradients, and climatic or other differences among regions. We demonstrate that individual-level and population-level performance traits can yield different predictors of plant performance. Therefore, future studies comparing plant performance in native and non-native ranges should include both plant and population characteristics and should also sample the target species from multiple regions in both ranges and along environmental gradients that comprehensively represent the niche of the species.

RESULTS: Microarray analysis of 6688 genes in imidacloprid-selected TPB (Im 1500FF) revealed 955 upregulated and 1277 downregulated (>= twofold) genes in Im 1500FF, with 369 and 485 of them annotated. Five P450 and nine esterase genes were significantly upregulated, and only one esterase gene and no P450 genes were down regulated. Other upregulated genes include helicases, phosphodiesterases, ATPases and kinases. Pathway analyses identified 65 upregulated cDNAs that encode 51 different enzymes involved in 62 different pathways, including P450 and esterase genes for drug and xenobiotic metabolisms. Sixty-four downregulated cDNAs code only 17 enzymes that are associated with only 23 pathways mostly related to food digestion. CONCLUSIONS: This study demonstrated a significant change in gene expression related to metabolic processes in imidacloprid-selected TPB, resulting in overexpression of P450 and esterase genes for potential excess detoxification and cross/multiple resistance development. The identification of these and other enzyme genes establishes a foundation to explore the complicity of potential imidacloprid resistance in TPB. Published 2014.

TI Surface conformations of an anti-ricin aptamer and its affinity for ricin determined by atomic force microscopy and surface plasmon resonance SO PHYSICAL CHEMISTRY CHEMICAL PHYSICS LA English DT Article ID LABEL-FREE DETECTION; SINGLE-MOLECULE; DNA; THROMBIN; BINDING AB We used atomic force microscopy (AFM) and surface plasmon resonance (SPR) to study the surface conformations of an anti-ricin aptamer and its specific binding affinity for ricin molecules. The effect of surface modification of the Au(111) substrate on the aptamer affinity was also estimated. The AFM topography images had a resolution high enough to distinguish different aptamer conformations. The specific binding site on the aptamer molecule was clearly located by the AFM recognition images. The aptamer on a Au(111) surface modified with carboxymethylated-dextran (CD) showed both similarities to and differences from the one without CD modification. The influence of CD modification was evaluated using AFM images of various aptamer conformations on the Au(111) surface. The affinity between ricin and the anti-ricin aptamer was estimated using the off-rate values measured using AFM and SPR. The SPR measurements of the ricin sample were conducted in the range from 83.3 pM to 8.33 nM, and the limit of detection was estimated as 25 pM (1.5 ng mL(-1)). The off-rate values of the ricin-aptamer interactions were estimated using both single-molecule dynamic force spectroscopy (DFS) and SPR as (7.3 +/- 0.4) x 10(-4) s(-1) and (1.82 +/- 0.067) x 10(-2) s(-1), respectively. The results show that single-molecule measurements can obtain different reaction parameters from bulk solution measurements. In AFM single-molecule measurements, the various conformations of the aptamer immobilized on the gold surface determined the availability of each specific binding site to the ricin molecules. The SPR bulk solution measurements averaged the signals from specific and non-specific interactions. AFM images and DFS measurements provide more specific information on the interactions of individual aptamer and ricin molecules.

Regrettably, it is a finite resource since phosphate rock (PR) is the main material used for production of P fertilizers. Globally, the demand for quality PR is escalating due to many factors including increasing human population. Inevitably, the demand for PR will exceed its supply capacity. This condition will be very difficult to manage as living systems have no alternative for P. Moreover, P use efficiency is low; only 15-20% of applied P is used by crops and animals. Globally, the remaining P is shunted into various waste streams. These waste streams include large quantities of effluents rich in P from both municipal and industrial wastewater treatment systems and manure from livestock production. The P present in these waste streams poses a threat to the environment by nutrient enrichment resulting in serious ecological issues such as eutrophication of waterways. However, P in these waste streams, if economically recovered, can contribute to a sustainable management of P resources. This review covers the following aspects: global importance of P as an essential nutrient; efficient and sustainable utilization of P; waste stream production, their suitability for P recovery, and limitations; current and emerging technologies for recovery of P; and the use of recovered P material. Finally, future research needs are identified associated with P recovery from waste streams and reuse in agriculture.

In this study, a near full-length genome sequence of a virus named RS3X (formerly classified as bovine rhinovirus type 1), isolated from infected cattle from the UK in the 1960s, was obtained and analyzed. Compared to other closely related Aphthoviruses, major differences were detected in the leader protease (L-pro), P1, 2B, and 3A proteins. Phylogenetic analysis revealed that RS3X was a member of the species bovine rhinitis A virus (BRAV). Using different codon-based and branch-site selection models for Aphthoviruses, including BRAV RS3X and foot-and-mouth disease virus, we observed no clear evidence for genomic regions undergoing positive selection. However, within each of the BRV species, multiple sites under positive selection were detected. The results also suggest that the probability (determined by Recombination Detection Program) for recombination events between BRVs and other Aphthoviruses, including foot-and-mouth disease virus was not significant. In contrast, within BRVs, the probability of recombination increases. The data reported here provide genetic information to assist in the identification of diagnostic signatures and research tools for BRAV.

TI Impacts of elevated atmospheric CO2 on nutrient content of important food crops SO SCIENTIFIC DATA LA English DT Article AB One of the many ways that climate change may affect human health is by altering the nutrient content of food crops. However, previous attempts to study the effects of increased atmospheric CO2 on crop nutrition have been limited by small sample sizes and/or artificial growing conditions. Here we present data from a metaanalysis of the nutritional contents of the edible portions of 41 cultivars of six major crop species grown using free-air CO2 enrichment ( FACE) technology to expose crops to ambient and elevated CO2 concentrations in otherwise normal field cultivation conditions. This data, collected across three continents, represents over ten times more data on the nutrient content of crops grown in FACE experiments than was previously available. We expect it to be deeply useful to future studies, such as efforts to understand the impacts of elevated atmospheric CO2 on crop macro- and micronutrient concentrations, or attempts to alleviate harmful effects of these changes for the billions of people who depend on these crops for essential nutrients.

Several superstructure types were included in this comprehensive effort, of which two-thirds were sawn timber stringer systems. In-depth inspections were conducted by the project team using visual, probing, and nondestructive evaluation (NDE) techniques to characterize the condition of the primary bridge superstructure components. The condition of the bridges was satisfactory and better for large percentages of the superstructure subsets, even within those regions of the country that have higher hazard ratings for exposed wood structures. Inspection results show that timber is a viable option for primary structural members in highway bridges with satisfactory service-life estimation of 70 years or more. These results shall provide the basis for the development of life-cycle cost analyses and bridge deterioration rate modeling for timber bridge superstructures in the future. C1 [Wacker, J.

Any UAS-based inspection must address questions regarding the design of the aerial platform, the choice of on-board inspection cameras, and the protocols for the human pilot to follow. The wide variety of currently available UASs and imaging systems, as well as a current lack of UAS inspection standards, can pose challenges to engineers attempting to design or test a new system. The Placer River Trail Bridge, located on the Alaskan Kenai Peninsula, has been chosen as a test site for the prototyping and testing of a new UAS bridge inspection system. The desired final inspection product guided the design and operation of the UAS. The research team emphasized a data-driven approach in developing the UAS and its associated inspection protocols. Goals included providing high-resolution scans of the bridge capable of detecting a variety of damage indicators, and producing a 3D virtual model of the bridge using Structure-from-Motion. The resulting designs of both the UAS and the inspection protocols are presented herein. The results indicate that such a data-driven approach can lead to UAS inspection systems that are more capable of meeting the needs of bridge asset managers and inspectors.

Better description of runoff patterns through modeling will help to understand and predict watershed sediment transport and water quality. In this study, CCHE2D, a numerical model for general free surface flow hydrodynamics, is applied to study the runoff and channel flow mixed problems. The model's capability of simulating the rainfall generated runoff processes is tested using analytical solutions, experimental data and field data. Comparison of numerical solutions with both analytic solutions and observed overland flows resulting from unsteady rainfalls and complex topography is satisfactory. The model is applied to a real world agricultural watershed in northwestern Mississippi, USA, in the Mississippi River Alluvial Plain known as the Mississippi Delta. The fine resolution of the numerical simulations resolved detailed runoff patterns in watersheds which can be used for soil erosion and gully development analyses.

A fixed-bed model focused on flow velocity and forces acting on an instrumented ELJ, and a movable-bed model focused on channel morphodynamics. The results show that: (1) downstream flow velocity, as expected, can be markedly affected by the presence of the ELJs, (2) both ELJ types afforded relatively large regions of bank protection, and (3) the relatively larger ELJ had a higher drag coefficient, relatively larger areas of bed deformation, and greater impact on the opposite stream bank as compared to the relatively smaller ELJ. These modeling results show that the style and size of ELJs can have a significant impact on flow resistance, bank protection, and stream channel responses, which should facilitate practitioners in the effective design of ELJs for natural rivers.

Two moisture deficit indicators based on soil matric potential had spatial and temporal patterns that were consistent with collected precipitation and reference ET data, as well as the state-wide historical trends. Actual ET was estimated by closing the soil water balance using in-situ soil moisture data, as well as by applying a surface energy balance approach to Landsat Thematic Mapper 5 imagery. When averaged over all years, weekly ET estimates with both approaches had a small mean signed difference (0.5 mm.week(-1)), but a large root mean square deviation (11.6 mm.week(-1)). This difference may be partly due to errors caused by interpolation of ET estimates between less-frequent satellite overpasses. Averaging over longer periods or modifying the interpolation methods may improve the accuracies for short-term remotely sensed ET estimates.

WS (124.2 g/L) was pretreated with dilute H2SO4 in two parallel tube reactors at 160 degrees C. The inhibitors were bio-abated by growing the fungus aerobically. The maximum ethanol produced by SSF of the bio-abated WS by the recombinant Escherichia coli FBR5 at pH 6.0 and 35 degrees C was 36.0 g/L in 83 h with a productivity of 0.43 g L-1 h(-1). This value corresponds to an ethanol yield of 0.29 g/g of WS which is 86% of the theoretical ethanol yield from WS. This is the first report on the production of ethanol by the recombinant bacterium from a lignocellulosic biomass at a pilot scale. Published by Elsevier Ltd.

The aim of this study was to increase production of caproate and valerate in short-term in vitro incubations. Coculture of mixed ruminal microbes with a rumen-derived strain of the bacterium Clostridium kluyveri converted cellulosic biomass (alfalfa stems or switchgrass herbage) plus ethanol to VFA mixtures that include valeric and caproic acids as the major fermentation products over a 48-72 h run time. Concentrations of caproate reached 6.1 g L-1, similar to or greater than those reported in most conventional carboxylate fermentations that employ substantially longer run times.

However, mechanisms regulating nutrient repartitioning during sexual maturation are not well understood. This study compared sexually maturing diploid (2 N) and sterile triploid (3 N) female rainbow trout to investigate effects of sexual maturation on expression of 35 genes involved in fatty acid metabolism, including genes within fatty acid synthesis, beta-oxidation, and cofactors of the mTOR and PPAR signaling pathways, in liver, white muscle, and visceral adipose tissue. Diploid fish were fed at different rations (0.25% and 0.50% tank biomass, and satiation) to determine effects of ration on gene expression. Gene expression was affected by ration level only in white muscle; erk and acat2 had higher expression in fish fed higher rations. On the other hand, sexual maturation affected gene expression across all three tissue types. Data indicate 2 N fish have higher expression of beta-oxidation genes within white muscle and within visceral adipose tissue. These findings support enhanced fatty acid mobilization within these tissues during sexual maturation. Higher expression of fatty acid synthesis genes in 3 N female liver is associated with higher expression of mTOR cofactors and ppar gamma, which reflects continued deposition of lipids in these fish. Furthermore, greater expression of genes involved in beta-oxidation pathways across ration levels in 2 N females suggests that sexual maturation and the associated maturation-related signals are stronger regulators of lipid metabolism-related genes rather the rations applied in the current study.

Indices of the chemical antioxidant assays, the reducing power, DPPH radical scavenging activity, and the hydroxyl radical scavenging activity (OH center dot) were improved by nanoencapsulation, compared to free BC. Caco-2 cells were treated with dichlorofluorescin diacetate (DCFH-DA) to determine the cellular antioxidant activity (CAA) of BC. CAA of SC, WPI, and SPI nanoparticles was higher (60%) compared to BC alone (45%). FTIR-ATR showed the presence of BC in the nanoparticle preparations. XRD and DSC analyses suggested that BC is amorphous in the nanoparticles. BC encapsulated by WPI had the most advantageous release properties. Release was low with pepsin but high with trypsin suggesting that WPI might be the best protein delivery vehicle to deliver BC to the intestine. (C) 2014 Elsevier Ltd. All rights reserved.

The objectives of this study were to compare differences between the oxidative barrier properties of biopolymer particle based encapsulation system (zein colloidal particles) and oil-in-water emulsions and evaluate the impact of these differences on oxidative stability of encapsulated bioactives. Methods: Both zein colloidal particles and oil-in-water emulsions were stabilized by casein protein. The oxidative barrier properties of the selected encapsulation systems were determined by measuring the permeation rate of peroxyl radicals and oxygen across the interface. Peroxyl radical permeation rates were correlated with stability of a model bioactive, curcumin and oxygen permeation rates were correlated with stability of another model bioactive, retinol. Results: Radical permeation rate was significantly higher in oil-in-water emulsions compared to zein colloidal particles, indicating enhanced barrier property of zein colloidal particles against peroxyl radical induced oxidation. Consistent with these results, stability of curcumin encapsulated in zein colloidal particles was significantly higher compared to that in oil-in-water emulsions. Oxygen permeation measurements showed no significant differences in the barrier properties of both encapsulation systems against oxygen permeation. Consistent with these results, the oxidative stability of retinol was similar in both encapsulation systems. Conclusions: The results of this study demonstrate the advantages of biopolymer particle based encapsulation system in limiting free radical induced oxidation of encapsulated bioactives and also demonstrate the ineffectiveness of both encapsulation systems in limiting oxygen permeation.

While CFG solution exhibited Newtonian fluid behavior with a very low viscosity even at a high concentration, the aqueous mixtures of CFG and some non-gelling polysaccharides (hyaluronan, guar gum, carboxymethylcellulose, hydroxyethylcellulose, konjac glucomannan, pectin and chitosan) showed a pseudoplastic fluid behavior. Furthermore, the addition of CFG showed a remarkable viscosifying action for the aqueous solutions of these non-gelling polysaccharides likely due to their interaction by hydrogen bonding. However, the viscosity behavior of CFG with some gelling polysaccharides such as methylcellulose, gellan gum, carrageenan, xanthan, may be based on a different mechanism. A proper model of intermolecular interaction between CFG and these gelling and non-gelling polysaccharides has been discussed and proposed. (C) 2014 Elsevier Ltd. All rights reserved.

TI Biosolids amendment dramatically increases sequestration of crop residue-carbon in agricultural soils in western Illinois SO APPLIED SOIL ECOLOGY LA English DT Article DE Carbon sink; Microbial metabolic quotient; Microbial stress; Midwest ID LONG-TERM APPLICATION; ORGANIC-MATTER; MICROBIAL BIOMASS; NITROGEN-FERTILIZATION; LAND RECLAMATION; NMR-SPECTROSCOPY; C-13 ABUNDANCE; DECOMPOSITION; DYNAMICS; ECOSYSTEM AB In agricultural soils, a large portion of C in crop residues (i.e., non-harvested plant parts left in the field) is annually lost to atmosphere due to the low C use metabolism of soil microorganisms adapting to the environmental stress (moisture stress and substrate C and N imbalance). In this study, we tested the hypothesis that amending soil with biosolids (treated sewage sludge with high stable organic matter and low C:N ratio) can improve the C metabolism of microorganisms in agricultural soils through alleviation of microbial stress, leading to increased sequestration of crop residue-C in agricultural soils. Biosolids were applied at a mean annual rate of 4.2 kg m (2) (dry weight) to eight agricultural fields (biosolids-amended) for 13 years (1972-1984) in western Illinois. Four agricultural fields (unamended) received chemical fertilizer as control. We measured the sequestration rate of crop residue-C in the soils over the span of 34 years (1972-2006) using a C-13 technique. We found dramatically greater sequestration rate of crop residue-C in biosolids-amended soil (32.5 +/- 1.7% of total crop residue-C) versus unamended soil (11.8+1.6%). Soil microbial metabolic quotient was significantly lower in biosolids-amended than in unamended fields, indicating that biosolid-amendment reduced soil microbial stress and improved microbial C metabolism. The study concludes use of a soil amendment with high stable C and low C:N is a valid approach to transform agricultural soils from current C-neutral status to a C sink. Biosolids represent a good choice of such soil amendments. (C) 2014 Elsevier B.V. All rights reserved.

Previously, we reported minimal differences inmost growth measurements between maturing 2N and 3N fish, but there were disparate changes in muscle proximate composition, visceral fat stores, and fatty acid contents of energy stores at 21 M with 3N females having greater lipid stores. Here, we report that gene expression profiles of liver and white muscle corresponded to the phenotypes with significant differences in expression at 20 M. Triploid females had increased expression of genes involved in fatty acid synthesis; including gpat, srebp1, acyl, acc, fas, and scd1 in liver and fas in muscle. Conversely, 2N muscle had increased expression of beta-oxidation genes cpt1b, cpt2, ehhadh, and acat2 and TORC1 inhibitors redd1, erk, mo25, and pras40. Diploid muscle also had increased expression of ppar beta along with increased expression of the fatty acid transporter gene cd36, and beta-oxidation genes cpt1a, cpt1c, aco, and acdhvl at 20 M. Additionally, 2N visceral adipose tissue had increased cpt1a expression at 21 M. Overall, data suggest that 3N females are undergoing higher levels of fatty acid synthesis while 2N females have higher levels of beta-oxidation during sexual maturation. Phenotypic data supports these findings with decreasing fatty acid stores in 2N females during this time period. Additionally, changes in gene expression are associated with altered expression within the mTOR and PPAR beta signaling pathways. (C) 2014 Elsevier B.V. All rights reserved.

Waters differed in two major characteristics: compared to SNARC water, WARU water contained appreciable dissolved organic matter (DOM) and very low concentrations of dissolved calcium and magnesium. In Experiment 1, fish were exposed to a bacterial challenge of F. columnare in aquaria with either SNARC or WARU water. Fish mortality at 4 d was 100% for fish in SNARC water, while no fish died in WARU water. Bacterial adhesion to gill surfaces also differed dramatically in the two waters and was approximately 1900-times higher for fish challenged in SNARC water (more than 800,000 bacterial CFUs/ng extracted DNA) than for fish challenged in WARU water (fewer than 450 CFUs/ng). Experiment 2 was conducted with a lower bacterial challenge to determine which factor, DOM or divalent cation concentration, caused the difference in mortality seen in Experiment 1. Complete removal of DOM from WARU water by carbon filtration did not affect bacterial adhesion to gills nor resulted in greater mortality in challenged fish. Consequently, DOM did not contribute to the differences in mortality seen in Experiment 1. However, removal of most calcium and magnesium from SNARC water by ion-exchange filtration resulted in decreased bacterial adhesion to gill and decreased mortality compared to un-altered SNARC water. It appears that the concentration of divalent cations (hardness) affects the pathogenesis of columnaris disease. Published by Elsevier B.V.

Dietary protein (DP) was replaced at 50, 60 and 70% using the 3011 meal or 40, 50 and 60% with the 3032 meal. Ingredient 3011 was a cooked and solvent-extracted meal from a high protein and low oligosaccharide soy cultivar; whereas, ingredient 3032 was a cold-pressed, low fat cake ground to a meal that originated from a medium protein, low oligosaccharide, low protease inhibitor soy cultivar. Experimental diets were isonitrogenous (45% crude protein, CP), isolipidic (13% lipid), isocaloric (12.6 kJ energy kg(-1) of diet) and were balanced for lysine (3.2%) and methionine + cysteine (2%). Taurine was supplemented at 1.5% in all diets. A commercial control diet (52% CP and 13% lipid) was included for a total of eight test diets. Twenty four round tanks (330 L) were each stocked with 20, 4 g yellowtail (Seriola lalandi). Tanks were supplied with recirculated seawater and each diet was randomly assigned to three replicate tanks. After a 10-week feeding trial, growth, survival, feed conversion ratio, protein efficiency ratio, protein retention, condition factor and carcass proximate composition were contrasted among dietary treatments. Results indicate that juvenile yellowtail fed diets in which the 3032 meal provided 50 and 60% of DP grew significantly (P < 0.001) better than those fed all other diets, including the FM-based (menhaden FM) and commercial control diets. Fish fed with the 3011 meal providing 50% of DP and those fed with the 3032 meal providing 40% of DP had similar growth performance which was slightly greater than the fish fed the FM reference diet. Minor intestinal histology differences were found among fish fed the 8 diets. Taken together these data indicates that the improved non-GM soybean meals supported better performance of juvenile yellowtail than fish fed the FM reference diet. No enteritis was detected even at high dietary inclusion levels. (C) 2014 Elsevier B.V. All rights reserved. C1 [Buentello, Alejandro] Navita Premium Feed Ingredients Inc, W Des Moines, IA 50266 USA.

Two blended poultry by-product meals (BP67, BP70), two blended chicken concentrates (CC66, CC70) and one standard pet-food grade poultry by-product meal (E150) were evaluated. The diets were formulated to contain 48% crude protein (CP) and 21 MJ/kg. Poultry by-products replaced 67% of the FM protein on an isonitrogenous basis. Trial 1 was a 10 week growth trial with juvenile (3.3 +/- 0.10 g) Florida pompano. No differences were detected in growth, efficiency, feed intake, protein productive value, or body composition between the by-product diets and a FM reference diet. Trial 2 examined protein, energy, dry matter, and organic matter digestibility and amino acid availability in 50.0 +/- 3.8 g Florida pompano. Apparent CP digestibility (65.6-72.9%) was significantly lower (P < 0.05) in the BP67 diet than the others, except BP70. No other differences were detected. In trial 3, Florida pompano (8.1 +/- 0.66 g) were fed a morning meal, and postprandial total ammonia-N (TAN) and urea excretion measured at 8 hourly increments. Ammonia increased 3.1-3.4 fold within 1 h. Rate of TAN excretion (mg TAN/kg.h) did not significantly decrease until 4-5 h postprandially. No differences in TAN accumulation were observed until 4 h when accumulation was significantly higher (P < 0.05) in CC66, and at 5 h lower in CC70 relative to the FM diet. Rate of urea excretion was constant. A slope ratio analysis indicated there were no differences in urea excretion among the treatments. Stepwise multiple regression suggested that methionine and lysine were the first and second limiting amino acids explaining 99.7% of the variability in weight gain. It is concluded that poultry by-products are suitable partial replacements for FM in Florida pompano diets. (C) 2014 Elsevier B.V. All rights reserved.

This study was conducted to investigate the potential effects of land use on soil detachment capacity by overland flow (D-c, kg m(-2) S-1) using natural undisturbed soil samples taken from four different land uses on the red loess soil and six different land uses on the yellow loess soil, and to quantify the relationships between soil detachment capacity and hydraulic parameters, soil properties, and root systems in the Loess Plateau. The collected samples were tested in a 4.0 m long, 035 m wide hydraulic flume under six different shear stresses (5.51-16.59 Pa). The result showed that both soil type and land use had significant effects on D-c. For two tested soils, the mean D-c of the yellow loess soil was 1.49 times greater than that of the red loess soil. For the red loess soil, D-c of cropland was the maximum, which was 5.57, 5.85, and 34.08 times greater than those of shrub land, orchard, and grassland, respectively. For the yellow loess soil, cropland was much more erodible than other five land uses. On average, the ratios of the cropland D-c to those of orchard, shrub land, woodland, grassland, and wasteland were 7.14, 12.29, 25.78, 28.45, and 46.43, respectively. The variability of D-c under different land uses was closely related to soil properties, root systems, and tillage operations. Soil detachment capacity was positively related to silt content, and inversely related to sand content, cohesion, water stable aggregate, aggregate median diameter, organic matter, and root density. The measured detachment capacity could be well estimated by measurable parameters of stream power, slope gradient, soil bulk density, median diameter, silt content, cohesion, and root density (Nash-Sutcliffe efficiency = 0.89).

In most cases, damage from insects is 'hidden', i.e. not visually detectable on the fruit surface. Consequently, traditional visual sorting techniques are generally inadequate for the detection and removal of olives with insect damage. In this study, the feasibility of using NIR spectroscopy to detect hidden insect damage is demonstrated. Using a genetic algorithm for feature selection (from 2 to 6 wavelengths) in combination with linear discriminant analysis (LDA), quadratic discriminant analysis (QDA) or k-nearest-neighbors (kNN) routines, classification error rates as low as 0.00% false negative, 12.50% false positive, and 6.25% total error were achieved, with an AUC value of 0.9766 and a Wilk's lambda of 0.3686 (P < 0.001). Multiplicative scatter correction, Savitzky-Golay spectral pre-treatment with 13 smoothing points and mean centering spectral pre-treatments were used. The optimal features corresponded to Abs[1108 nm], Abs[1232 nm], Abs[1416 nm], Abs[1486 nm] and Abs[2148 nm]. (C) 2014 Elsevier B.V. All rights reserved.

During this period growth was rapid with shoot biomass ranging from 0.93-2.2 g plant(-1) (280-650 kg ha(-1)) DW. Shoot Cd and Zn concentrations for the four populations evaluated ranged from 460-600 and 2600-2900 mg kg(-1) DW respectively. Cadmium and Zn Translocation Factors (shoot/root) for the populations tested ranged from 0.91-1.0 and 1.7-2.1 and Bioaccumulation Factors ranged from 12-15 and 1.2-1.3. We conclude that optimizing the use of fungicidal sprays, acidic soil pH, planting density and increasing the effective cropping period will increase rates of Cd and Zn removal enough to facilitate practical Cd phytoextraction from rice paddy soils in Thailand.

Furthermore, fibres with antimicrobial properties were generated by incorporating carvacrol and THC as antimicrobial agents and the biocide effect against Listeria monocytogenes was studied. Initially, PLA blow spun fibres containing BCNW were optimized in terms of morphology and thermal properties. The addition of BCNW was seen to significantly increase the viscosity and surface tension of solutions, restricting the capacity to form fibres for concentrations greater than 30 wt.-% BCNW. 15 wt.-% BCNW was selected as the optimum nanofiller loading as it led to the most uniform fibres morphology, with BCNW homogeneously distributed along the fibres' axis. Subsequently, carvacrol and THC were incorporated into the fibres to confer them with antimicrobial properties, although the hydrophobic PLA matrix did not provide an efficient release of the antimicrobials. Thus, hydrophilic substances were added in order to trigger the antimicrobials release through water sorption mechanisms. The addition of the BCNW filler was not seen to significantly increase the antimicrobial capacity of the fibres by itself and, hence, gelatin was added to help promoting further the hydrophylicity and biocide performance of the fibres. Nevertheless, for the more hydrophilic THC, the biocide capacity of the fibres with gelatin was accentuated further by the presence of the BCNW.

Results show that plant polyphenols and alpha-tocopherol significantly decreased pH, lipid oxidation (formation of thiobarbituric acid reactive substances) and residual nitrite content compared with control (P < 0.05) at the end of ripening. Microbial counts, biogenic amines, and N-nitrosodimethylamine (NDMA) contents in dry-cured bacons were significantly affected by plant polyphenols or alpha-tocopherol (P < 0.05), with GTP being the most effective in reducing aerobic plate counts (APC), Enterobacteriaceae, and biogenic amines (putrescine, cadaverine, histamine, tyramine and spermine), as well as in inhibiting the NDMA formation (P < 0.05). Principal component analysis indicated that there were positive correlations between physicochemical factors, biogenic amines (putrescine, cadaverine, histamine, tyramine and spermine), NDMA and APC, and between the TBARS and sodium nitrite. There was a negative correlation between NDMA and nitrite. These findings suggest plant polyphenols, especially GTP, could be utilized for processing dry-cured bacons to improve quality, shelf life, and safety of finished products. (C) 2014 Elsevier Ltd.

TI A method to determine particle size distribution in soils with gypsum SO GEODERMA LA English DT Article DE Gypsiferous soils; Gypseous soils; Soil texture; Aridisols; Soil analysis ID STABILITY AB Gypseous (>40% gypsum) and gypsiferous (1 to 40% gypsum) soils are estimated to comprise from 100 million to 200 million ha globally including over 1 million ha in the U.S. More intensive land use on these soils has resulted in greater demand for information on distribution, properties, and behavior of these soils. Common laboratory methods for determining particle size distribution of soils involve pretreatment to remove gypsum and more soluble salts since they interfere with sample dispersion and establishment of a stable clay suspension. Thus, particle size measurements using standard methods with pretreatment to remove gypsum only reflect the size distribution of essentially insoluble, dominantly silicate minerals, and do not reflect the size distribution of the whole soil including gypsum. Forcing results into a silicate-mineral basis in moderate to high gypsum soils can profoundly distort analytical results. The objective of this project was to develop and evaluate an alternative method of particle size measurement for soils with gypsum that includes size distribution of gypsum particles. Three disaggregation methods for estimation of total sand and sand separates were evaluated: 1) drying sieving, 2) shaking in a 7:3 ethanol:water solution, and 3) sonication in a 7:3 ethanol:water solution. Evaluation of samples with and without gypsum indicated that the sonication method was the most effective for disaggregation as indicated by sand fraction distribution and microscopic grain evaluations. Application of the method to samples from three gypseous pedons yielded grain-size distributions that better agreed with hand textural class estimates than conventional grain-size analysis by standard methods that included pretreatment to remove gypsum. Comparison of CEC/clay and 1500 kPa water/clay ratios for the samples between the two methods also suggested that the proposed method yielded clay contents more consistent with other property data for the same horizons. Improved particle size evaluations for soils containing gypsum, especially those with high gypsum contents, will improve the understanding and ability to interpret and predict behavior of these unique soils.

TI Control of vegetable pests in Benin - Farmers' preferences for eco-friendly nets as an alternative to insecticides SO JOURNAL OF ENVIRONMENTAL MANAGEMENT LA English DT Article DE Benefit-cost analysis; Choice experiment; Integrated pest management; Pesticides; Insect net; Stated preference; Urban agriculture; West Africa ID PESTICIDE USE; CHOICE EXPERIMENT; FOOD SECURITY; WEST-AFRICA; MIXED LOGIT; SCALE HETEROGENEITY; CABBAGE PRODUCTION; URBAN AGRICULTURE; WILLINGNESS; MANAGEMENT AB We investigated if eco-friendly nets (EFNs) are a viable and acceptable alternative to extremely high levels of insecticide use in vegetable production. Using a choice experiment, we found that vegetable producing farmers in Benin preferred all of the characteristics of EFNs except the higher labor requirements. The nets had been distributed in a trial phase for free but in the long run farmers would need to purchase the EFNs. The break-even point for investing in nets was found to vary with the lifespan of EFNs, their purchase price and potential health benefits from avoiding large quantities of insecticides. To break even the nets need to be used for at least two production cycles. To overcome risk-averse farmer's reluctance to adopt EFNs we propose a credit and warranty scheme along with the purchase of the nets. The study's findings can guide the implementation of EFNs in other African countries as part of integrated pest management with global benefits for the environment and human health.

TI Origin of carbon in aromatic and olefin products derived from HZSM-5 catalyzed co-pyrolysis of cellulose and plastics via isotopic labeling SO APPLIED CATALYSIS B-ENVIRONMENTAL LA English DT Article DE Catalytic fast pyrolysis; Isotopic labeling; Reaction mechanisms; Olefin; Aromatic ID LOW-DENSITY POLYETHYLENE; FLUIDIZED-BED REACTOR; LIGNOCELLULOSIC BIOMASS; REACTION PATHWAYS; CONVERSION; CRACKING; WASTE; ZSM-5; POLYSTYRENE; MECHANISM AB Catalytic pyrolysis over HZSM-5 is an effective method for the conversion of biomass to aromatic hydrocarbons, albeit with low yield and short catalyst lifetimes. Addition of co-reactants rich in carbon and hydrogen can enhance yield and possibly increase catalyst lifetimes by reducing coke formation. Particularly, the catalytic co-pyrolysis of plastic and biomass has been shown to enhance conversion to aromatic hydrocarbons, and also offers a method for productive disposal of waste agricultural plastics. In an effort to determine the origin of the carbon (plastic or biomass) in the products from this catalytic co-pyrolysis, mixtures of uniformly labeled C-13 cellulose and non-labeled plastic including polyethylene terephthalate, polypropylene, high density polyethylene, low density polyethylene and polystyrene were subjected to catalytic fast pyrolysis (CFP) at 650 degrees C in the presence of HZSM-5. A micro pyrolyzer coupled with GC/MS (py-GC/MS) advised product distributions and mass spectral data was used to determine the distribution of biogenic carbon and plastic derived carbon in the products. The results demonstrate that aromatic hydrocarbon products formed from the CFP of mixtures of cellulose and plastic are composed mostly of molecules containing carbon of mixed origin. Data on the distribution of C-13(x) C-12(y) from the products followed in this study show that polyolefin mixtures with cellulose favor the formation of alkyl benzenes that incorporate carbon from both sources. Utilization of aromatic polymers (polystyrene or polyethylene terephthalate) is more selective for formation of naphthalenes with carbon derived from both products. The distribution of various(13)C(x) C-12(y) products is used to suggest active mechanisms that result in the formation of the observed products. Published by Elsevier B.V.

To realize the potential of this system, many tools have been developed (e. g., the complete genome sequence, a large collection of natural accessions, a high density genetic map, BAC libraries, EST sequences, microarrays, etc.). In this chapter, we describe a high-efficiency transformation system, an essential tool for a modern model system. Our method utilizes the natural ability of Agrobacterium tumefaciens to transfer a well-defined region of DNA from its tumor-inducing (Ti) plasmid DNA into the genome of a host plant cell. Immature embryos dissected out of developing B. distachyon seeds generate an embryogenic callus that serves as the source material for transformation and regeneration of transgenic plants. Embryogenic callus is cocultivated with A. tumefaciens carrying a recombinant plasmid containing the desired transformation sequence. Following cocultivation, callus is transferred to selective media to identify and amplify the transgenic tissue. After 2-5 weeks on selection media, transgenic callus is moved onto regeneration media for 2-4 weeks until plantlets emerge. Plantlets are grown in tissue culture until they develop roots and are transplanted into soil. Transgenic plants can be transferred to soil 6-10 weeks after cocultivation. Using this method with hygromycin selection, transformation efficiencies average 42 %, and it is routinely observed that 50-75 % of cocultivated calluses produce transgenic plants. The time from dissecting out embryos to having the first transgenic plants in soil is 14-18 weeks, and the time to harvesting transgenic seeds is 20-31 weeks.

This technology can also be used to make improved crop varieties for use in the field. To apply this powerful tool to red clover, an important forage legume, a population of red clover with high potential for regeneration in tissue culture has been developed. Here we provide a detailed procedure for Agrobacterium-mediated transformation of genotypes derived from this regenerable population. We have successfully used this methodology to express beta-glucuronidase (GUS) reporter genes as well as for hairpin RNA-mediated silencing of endogenous genes for polyphenol oxidase and a transferase crucial in phaselic acid accumulation.

Importantly, the various changes are examined analytically, empirically and numerically in both non-dominated and dominated asymmetric oligopolies. In this regard, the results indicate that firms in a dominated oligopoly (one firm of market share larger than or equal to 50%) behave differently compared to firms in a non-dominated oligopoly (each firm of market share less than 50%) in response to changes in model parameters. Furthermore, changes in model parameters are investigated in terms of their relative influential impact on a variety of equilibrium measures. In this regard, the findings indicate that for the analyzed model the marketing parameters exert much more influence on the equilibrium measures than the operations parameters. Additionally, a change in the mode of competition from non-cooperation (oligopoly) to cooperation (joint ownership) dictates that strong asymmetric firms (of favorable marketing and operations parameters) continue advertising (but at lower levels) and weak asymmetric firms (of less favorable parameters) cease advertising altogether.

Accordingly, the effort to develop efficient and reliable Salmonella detection methods continues. This paper reviews and describes the development and application of commercially available Salmonella detection methods. These are categorized into several groups based on the principle applied: conventional culture methods, immunology-based assays, nucleic acid-based assays, miniaturized biochemical assays, and biosensors. Conventional culture methods serve as the basis in food testing laboratories despite rather laborious and time-consuming protocols. Considerable progress in rapid methods using emerging technologies yield faster answers and higher throughput of samples. This paper also shows and analyzes Salmonella test results and summarizes the features and limitations of the studies involving Salmonella detection methods developed for emergency response, mainly by food emergency response laboratories participating during recent fiscal years. The emergency response laboratories utilize Salmonella detection methods possessing properties that include simplicity, versatility, high sensitivity, good specificity, and cost efficiency. Collaboration of the food emergency response laboratories in the development of these technologies is important essentially to compare for the purpose of continually improving Salmonella detection methods.

The combination of allyl isothiocyanate (AIT) and modified atmosphere (MA) was applied and proved effective to retard the growth of P. aeruginosa. The objective of this research was to develop simple mathematical models to predict the growth behavior of P. aeruginosa in catfish fillet and its potential storage time (in abuse temperature condition) as a function of AIT and temperature with/without MA treatment. The antimicrobial effect of gaseous AIT (0, 18 and 36 mu L/L) on the growth of P. aeruginosa cocktail was evaluated at 8,15 and 20 degrees C. Furthermore, the effects of MA (49% CO2, 50.5% N-2 and 0.5% O-2) alone and AIT/MA combination were also investigated. These data obtained through an experimental design were used for model development. The regression models for lag phase, growth rate and "shelf life" (based on P. aeruginosa which closely related to Pseudomonas fluorescens and Pseudomonas pudita and all belong to the same RNA group used to classify the Pseudomonas at the subgenus level) were validated experimentally. Surface plot of models was also drawn to lucidly represent the interaction of AIT and temperature. The developed models may provide useful information for food industry in designing or selecting the proper packaging system with incorporation of AIT to attain the food safety with acceptable "shelf life" of fresh fish products under specified and potential abuse (with temperature deviation) distribution and storage conditions.

One of these, aflatoxin B-1 can be metabolized by mammals to aflatoxin M-1, a form that retains potent carcinogenicity and which can be excreted into milk. Direct analysis in real time (DART) ionization coupled to a high resolution mass spectrometer (MS) was used for the rapid quantitative analysis of a common form of aflatoxin, AFM(1), extracted from cow milk. Sample preparation procedure and instrument parameter settings were optimized to obtain sensitive and accurate determination of AFM(1). The lowest calibration level (LCL) for aflatoxin AFM(1) was 0.1 mu g/kg. Quantitative analysis was performed with the use of matrix-matched standards employing a C-13-labeled internal standard for AFM(1). DART-MS of spiked milk extracts gave linear response over the range of 0.1-2.5 mu g/kg. Good recoveries (94.7-109.2%) and repeatabilities (RSD 13.5-9.6%) were obtained at spiking levels of 0.5 and 2.0 mu g/kg. The results of the study further demonstrate the potential of ambient ionization-MS techniques for the sensitive, convenient and rapid quantitative determination of mycotoxins from difficult matrices.

The US Food and Drug Administration Food Code recommend that packaged fresh-cut leafy green vegetables be kept no warmer than 5 C at all times to ensure food safety. Substantial temperature variations, however, within the widely used open refrigerated display cases used in retail stores are known to present the technical challenge of complying with this federal guidance for industry. This study determined the extent of the spatial and temporal temperature variations within two commercial open-refrigerated display cases under different operating conditions, and their impact on the quality and microbial growth of packaged baby spinach products. The packaged products were received within 2 d of commercial processing and temperature data loggers were placed inside-and-outside of each bag. All bags were immediately loaded in the display cases and the overall visual quality, tissue electrolyte leakage, total aerobic mesophilic bacteria and psychrotrophic bacteria were evaluated for each bag. Results from this study showed that the temperature variation in the cases was dependent on spatial location, thermostat setting, and defrost cycle interval and duration of defrost. The largest temperature differentials were found for samples located in the front and back rows of the display cases. Samples located in the front rows had the highest temperature due to heat penetration from the surrounding ambient environment, while those in the back were damaged as temperatures fell below freezing. These products received low quality scores and had higher tissue electrolyte leakage. In order to reduce the large temperature variations in the display cases, insulating foam boards were installed which significantly (P < 0.05) decreased the temperature variation by 3.5 degrees C and enabled samples in the front rows of the cases to remain less than 5 degrees C as recommended by the FDA. These results suggest that the quality and safety of packaged ready-to-eat spinach at retail will benefit from improvements in open refrigerated case design or the utilization of insulation, doors or curtains.

In the last decade, there has been a general world-wide increase in starch concentrations in sugarcane. Industrial alpha-amylases have been used for many years to mitigate issues arising from starch in the sugarcane industry. Mixed results have prompted further studies of the behaviour of different physical forms of starch and their interactions with alpha-amylases during processing. By using corn starch as a reference in model juices and syrups, processing parameters, activities, and hydrolysis of insoluble, swollen, and soluble starch forms were evaluated for two commercial alpha-amylases with high (HT) and intermediate (IT) temperature stability, respectively. The ability of starch to solubilise across a sugarcane factory is largely limited by increased Brix values. Optimum target locations and conditions for the application of alpha-amylases in sugarcane processing are discussed in detail. Published by Elsevier Ltd.

D-aas such as D-Asp (aspartic acid), D-Glu (glutamic acid), combined D-[Asp/Glu] and others were each prepared in a cocktail of 9 other D-aas, along with L-amino acids (L-aas) and controls. Each sample was mixed with a pooled plasma from peanut-allergic donors, and tested by ELISA (enzyme-linked immunosorbent assay) and Western blots for IgE binding to peanut allergens. Results showed that D-[Asp/Glul (4 mg/ml) inhibited IgE binding (75%) while D-Glu, D-Asp and other D-aas had no inhibitory effect. A higher inhibition was seen with D-[Asp/Glu] than with L-[Asp/Glu]. We concluded that IgE was specific for D-[Asp/Glu], not D-Asp or D-Glu, and that D-[Asp/Glu] was more reactive than was L-[Asp/Glu] in IgE inhibition. The finding indicates that D-[Asp/Glu] may have the potential for removing IgE or reducing IgE binding to peanut allergens in vitro. Published by Elsevier Ltd.

In this study we evaluated total Se and the different chemical species of Se in broccoli and carrots grown in soils amended with ground shoots of the Se-hyperaccumulator Stanleya pinnata. With increasing application rates of S. pinnata, total plant Se concentrations increased to nutritionally ideal levels inside edible parts. Selenium compounds in aqueous extracts were analyzed by SAX-HPLC-ICPMS and identified as a variety of mainly organic-Se forms. Together with bulk Se K-edge X-ray absorption near-edge structure (XANES) analysis performed on broccoli florets, carrot roots and shoots, dried ground S. pinnata, and the amended soil at post-plant, we demonstrate that Se-enriched S. pinnata is valuable as a soil amendment for enriching broccoli and carrots with healthful forms of organic-Se.

In reality, they contain little sugar alcohol. Numerous research groups have reported zero detectable amounts of sugar alcohol in fully ripe Rubus fruit, with the exception of three out of 82 Rubus fruit samples (cloudberry 0.01 g/100 g, red raspberry 0.03 g/100 g, and blackberry 4.8 g/100 g*; *highly unusual as 73 other blackberry samples contained no detectable sorbitol). Past findings on simple carbohydrate composition of Rubus fruit, other commonly consumed Rosaceae fruit, and additional fruits (24 genera and species) are summarised. We are hopeful that this review will clarify Rosaceae fruit sugar alcohol concentrations and individual sugar composition; examples of non-Rosaceae fruit and prepared foods containing sugar alcohol are included for comparison.

Cadmium phytoextraction would alleviate current land use constraints. Unamended farm soil, and biosolids amended farm and mine soils were obtained from a Fulton Co., IL biosolids management facility. Soils contained 0.16, 22.8, 45.3 mg Cd kg(-1) and 43.1, 482, 812 mg Zn kg(-1) respectively with initial pH 6.0, 6.1, 6.4. In greenhouse studies, Swiss chard (Beta vulgaris var. cicla), a Cd-accumulator maize (inbred B37 Zea mays) and a southern France Cd-hyperaccumulator genotype of Noccaea caerulescens were tested for Cd accumulation and phytoextraction. Soil pH was adjusted from similar to 5.5-7.0. Additionally 100 rice (Oryza sativa) genotypes and the Ni-hyperaccumulator Alyssum murale were screened for potential phytoextraction use. Chard suffered phytotoxicity at low pH and accumulated up to 90 mg Cd kg(-1) on the biosolids amended mine soil. The maize inbred accumulated up to 45 mg Cd kg(-1) with only mild phytotoxicity symptoms during early growth at pH > 6.0. N. caerulescens did not exhibit phytotoxicity symptoms at any pH, and accumulated up to 235 mg Cd kg(-1) in 3 months. Reharvested N. caerulescens accumulated up to 900 mg Cd kg(-1) after 10 months. Neither Alyssum nor 90% of rice genotypes survived acceptably. Both N. caerulescens and B37 maize show promise for Cd phytoextraction in IL and require field evaluation; both plants could be utilized for nearly continuous Cd removal. Other maize inbreds may offer higher Cd phytoextraction at lower pH, and mono-cross hybrids higher shoot biomass yields. Further, maize grown only for biomass Cd maximum removal could be double-cropped. C1 [Broadhurst, C.

Results: In this work we have tested a dozen commercial bacterial genomic DNA extraction methodologies on an average of 7.70 x 106 (+/- 9.05%), 4.77 x 108 (+/- 31.0%), and 5.93 x 108 (+/- 4.69%) colony forming units (CFU) associated with 3 cultures (n = 3) each of Brochothrix thermosphacta (Bt; Gram-positive), Shigella sonnei (Ss; Gram-negative), and Escherichia coli O79 (Ec; Gram-negative). We have utilized real-time PCR (qPCR) quantification with two specific sets of primers associated with the 16S rRNA " gene" to determine the number of copies CFU-1 by comparing the unknown target DNA qPCR results with standards for each primer set. Based upon statistical analyses of our results, we determined that the Agencourt Genfind v2, High Pure PCR Template Prep Kit, and Omnilyse methods consistently provided the best yield of genomic DNA ranging from 141 to 934, 8 to 21, and 16 to 27 16S rDNA copies CFU-1 for Bt, Ss, and Ec. If one assumes 6-7 copies of the 16S rRNA gene per genome, between 1 and 3 genomes per actively dividing cell and = 100 cells CFU-1 for Bt (found to be a reasonable assumption using an optical method expounded upon herein) or between 1 and 2 cells CFU-1 for either Ss or Ec, then the Omnilyse procedure provided nearly quantitative extraction of genomic DNA from these isolates (934 19.9 copies CFU-1 for Bt; 20.8 +/- 2.68 copies CFU-1 for Ss; 26.9 +/- 3.39 copies CFU-1 for Ec). The Agencourt, High Pure, and Omnilyse technologies were subsequently assessed using 5 additional Gram-positive and 10 Gram-negative foodborne isolates (n = 3) using a set of " universal" 16S rDNA primers. Conclusion: Overall, the most notable DNA extraction method was found to be the Omnilyse procedure which is a " bead blender" technology involving high frequency agitation in the presence of zirconium silicate beads.

TI Comparisons of De Novo Transcriptome Assemblers in Diploid and Polyploid Species Using Peanut (Arachis spp.) RNA-Seq Data SO PLOS ONE LA English DT Article ID BURROWS-WHEELER TRANSFORM; CULTIVATED PEANUT; READ ALIGNMENT; HYPOGAEA L.; GENOME; GENERATION; DISCOVERY; RELATIVES; PROGRAM; MARKERS AB The narrow genetic base and limited genetic information on Arachis species have hindered the process of marker-assisted selection of peanut cultivars. However, recent developments in sequencing technologies have expanded opportunities to exploit genetic resources, and at lower cost. To use the genetic information for Arachis species available at the transcriptome level, it is important to have a good quality reference transcriptome. The available Tifrunner 454 FLEX transcriptome sequences have an assembly with 37,000 contigs and low N50 values of 500-751bp. Therefore, we generated de novo transcriptome assemblies, with about 38 million reads in the tetraploid cultivar OLin, and 16 million reads in each of the diploids, A. duranensis K38901 and A. ipaensis KGBSPSc30076 using three different de novo assemblers, Trinity, SOAPdenovo-Trans and TransAByss. All these assemblers can use single kmer analysis, and the latter two also permit multiple kmer analysis. Assemblies generated for all three samples had N50 values ranging from 1278-1641 bp in Arachis hypogaea (AABB), 1401-1492 bp in Arachis duranensis (AA), and 1107-1342 bp in Arachis ipaensis (BB). Comparison with legume ESTs and protein databases suggests that assemblies generated had more than 40% full length transcripts with good continuity. Also, on mapping the raw reads to each of the assemblies generated, Trinity had a high success rate in assembling sequences compared to both TransAByss and SOAPdenovo-Trans. De novo assembly of OLin had a greater number of contigs (67,098) and longer contig length (N50=1,641) compared to the Tifrunner TSA. Despite having shorter read length (2x50) than the Tifrunner 454FLEX TSA, de novo assembly of OLin proved superior in comparison. Assemblies generated to represent different genome combinations may serve as a valuable resource for the peanut research community.

TI An Ephemeral Sexual Population of Phytophthora infestans in the Northeastern United States and Canada SO PLOS ONE LA English DT Article ID MULTILOCUS GENOTYPE DATA; RECENT CLONAL LINEAGES; CENTRAL MEXICO; LATE BLIGHT; DNA POLYMORPHISM; GENOME SEQUENCES; TOLUCA VALLEY; POTATO; OOSPORES; MARKERS AB Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013, 20 rare and diverse genotypes of P. infestans were detected in a region that centered around central New York State. The ratio of A1 to A2 mating types among these genotypes was close to the 50: 50 ratio expected for sexual recombination. These genotypes were diverse at the glucose-6-phosphate isomerase locus, differed in their microsatellite profiles, showed different banding patterns in a restriction fragment length polymorphism assay using a moderately repetitive and highly polymorphic probe (RG57), were polymorphic for four different nuclear genes and differed in their sensitivity to the systemic fungicide mefenoxam. The null hypothesis of linkage equilibrium was not rejected, which suggests the population could be sexual. These new genotypes were monomorphic in their mitochondrial haplotype that was the same as US-22. Through parentage exclusion testing using microsatellite data and sequences of four nuclear genes, recent dominant lineages US-8, US-11, US-23, and US-24 were excluded as possible parents for these genotypes. Further analyses indicated that US-22 could not be eliminated as a possible parent for 14 of the 20 genotypes. We conclude that US-22 could be a parent of some, but not all, of the new genotypes found in 2010 and 2011. There were at least two other parents for this population and the genotypic characteristics of the other parents were identified.

LAM.; POPULATION-STRUCTURE; INTERACTIVE TREE; IPOMOEA; DISPERSAL; ORIGIN; MICROSATELLITES; POLYMORPHISMS; ANNOTATION AB Sweet potato (Ipomoea batatas L.) is the seventh most important food crop due to its distinct advantages, such as adaptability to different environmental conditions and high nutritional value. Assessing the genetic diversity of this important crop is necessary due to the constant increase of demand for food and the need for conservation of agricultural and genetic resources. In Puerto Rico (PR), the genetic diversity of sweet potato has been poorly understood, although it has been part of the diet since Pre-Columbus time. Thus, 137 landraces from different localities around PR were collected and subjected to a genetic diversity analysis using 23 SSR-markers. In addition, 8 accessions from a collection grown in Gurabo, PR at the Agricultural Experimental Station (GAES), 10 US commercial cultivars and 12 Puerto Rican accessions from the USDA repository collection were included in this assessment. The results of the analysis of the 23 loci showed 255 alleles in the 167 samples. Observed heterozygosity was high across populations (0.71) while measurements of total heterozygosity revealed a large genetic diversity throughout the population and within populations. UPGMA clustering method revealed two main clusters. Cluster 1 contained 12 PR accessions from the USDA repository collection, while cluster 2 consisted of PR landraces, US commercial cultivars and the PR accessions from GAES. Population structure analysis grouped PR landraces in five groups including four US commercial cultivars. Our study shows the presence of a high level of genetic diversity of sweet potato across PR which can be related to the genetic makeup of sweet potato, human intervention and out-crossing nature of the plant. The history of domestication and dispersal of sweet potato in the Caribbean and the high levels of genetic diversity found through this study makes sweet potato an invaluable resource that needs to be protected and further studied.

Don) is of high interest in forest breeding and conservation because of its high susceptibility to the invasive disease white pine blister rust (WPBR, caused by the fungus Cronartium ribicola J. C. Fisch). However, WWP lacks genomic resource development and is evolutionarily far away from plants with available draft genome sequences. Here we report a single nucleotide polymorphism (SNP) study by bulked segregation-based RNA-Seq analysis. Results: A collection of resistance germplasm was used for construction of cDNA libraries and SNP genotyping. Approximately 36-89 million 2 x 100-bp reads were obtained per library and de-novo assembly generated the first shoot-tip reference transcriptome containing a total of 54,661 unique transcripts. Bioinformatic SNP detection identified > 100,000 high quality SNPs in three expressed candidate gene groups: Pinus highly conserved genes (HCGs), differential expressed genes (DEGs) in plant defense response, and resistance gene analogs (RGAs). To estimate efficiency of in-silico SNP discovery, genotyping assay was developed by using Sequenom iPlex and it unveiled SNP success rates from 40.1% to 61.1%. SNP clustering analyses consistently revealed distinct populations, each composed of multiple full-sib seed families by parentage assignment in the WWP germplasm collection. Linkage disequilibrium (LD) analysis identified six genes in significant association with major gene (Cr2) resistance, including three RGAs (two NBS-LRR genes and one receptor-like protein kinase -RLK gene), two HCGs, and one DEG. At least one SNP locus provided an excellent marker for Cr2 selection across P. monticola populations. Conclusions: The WWP shoot tip transcriptome and those validated SNP markers provide novel genomic resources for genetic, evolutionary and ecological studies. SNP loci of those candidate genes associated with resistant phenotypes can be used as positional and functional variation sites for further characterization of WWP major gene resistance against C. ribicola. Our results demonstrate that integration of RNA-seq-based transcriptome analysis and high-throughput genotyping is an effective approach for discovery of a large number of nucleotide variations and for identification of functional gene variants associated with adaptive traits in a non-model species.

TI Genome-wide association study of Fusarium ear rot disease in the USA maize inbred line collection SO BMC PLANT BIOLOGY LA English DT Article DE Association analysis; Disease resistance; Genomic selection; Maize; Quantitative trait ID FALSE DISCOVERY RATE; FUMONISIN CONTAMINATION; KERNEL INFECTION; RESISTANCE; CORN; VERTICILLIOIDES; MONILIFORME; POPULATIONS; GENES; IDENTIFICATION AB Background: Resistance to Fusarium ear rot of maize is a quantitative and complex trait. Marker-trait associations to date have had small additive effects and were inconsistent between previous studies, likely due to the combined effects of genetic heterogeneity and low power of detection of many small effect variants. The complexity of inheritance of resistance hinders the use marker-assisted selection for ear rot resistance. Results: We conducted a genome-wide association study (GWAS) for Fusarium ear rot resistance in a panel of 1687 diverse inbred lines from the USDA maize gene bank with 200,978 SNPs while controlling for background genetic relationships with a mixed model and identified seven single nucleotide polymorphisms (SNPs) in six genes associated with disease resistance in either the complete inbred panel (1687 lines with highly unbalanced phenotype data) or in a filtered inbred panel (734 lines with balanced phenotype data). Different sets of SNPs were detected as associated in the two different data sets. The alleles conferring greater disease resistance at all seven SNPs were rare overall (below 16%) and always higher in allele frequency in tropical maize than in temperate dent maize. Resampling analysis of the complete data set identified one robust SNP association detected as significant at a stringent rho-value in 94% of data sets, each representing a random sample of 80% of the lines. All associated SNPs were in exons, but none of the genes had predicted functions with an obvious relationship to resistance to fungal infection. Conclusions: GWAS in a very diverse maize collection identified seven SNP variants each associated with between 1% and 3% of trait variation. Because of their small effects, the value of selection on these SNPs for improving resistance to Fusarium ear rot is limited. Selection to combine these resistance alleles combined with genomic selection to improve the polygenic background resistance might be fruitful. The genes associated with resistance provide candidate gene targets for further study of the biological pathways involved in this complex disease resistance.

Several lilac aldehydes and veratrole were progressively reduced after moth exposure without oviposition (by 30 to 40% after 24 hours and by 60 to 90% after 72 hours), but beta-myrcene and beta-pinene emissions increased by 200 to 300% only when exposure involved oviposition. Exposing S. latifolia to H. bicruris floral interaction without oviposition yielded no change in volatile organic compound (VOC) emission of neighboring S. latifolia; with oviposition, neighboring plants had 80 to 126% increases in emission rates for beta-myrcene and beta-pinene. Progressive reduction of S. latifolia VOC emission rates might help plants to avoid nursery pollinator oviposition. In contrast, with H. bicruris oviposition on S. latifolia flowers some VOCs (common herbivore-induced plant volatiles i.e. HIPVs) were induced. Whether oviposition occurred on S. latifolia strongly influenced neighboring plant VOC emission.

TI Rediscovery of Eugenia fajardensis (Myrtaceae), a rare tree from the Puerto Rican Bank SO PHYTOTAXA LA English DT Article DE Antilles; Caribbean; Culebra; Fajardo's big guava; "guayabota de Fajardo"; Puerto Rico; Vieques; West Indies AB Eugenia fragrans var.? fajardensis was described in 1895 and raised to species status in 1923 as E. fajardensis. In 1925, it was relegated to the synonymy of Anamomis fragrans (Myrcianthes fragrans). Since 2001, we have re-discovered wild plants and herbarium specimens, including a previously unidentified isotype of E. fajardensis, supporting the validity of this species. Here we designate a lectotype and an epitype for E. fajardensis. In addition, we provide: 1) an extended description for the species including the previously unknown flowers and fruits, an illustration, and photographs of live plants, 2) a key for the 24 taxa of Eugenia reported for Puerto Rico and the Virgin Islands, and 3) descriptions of the three known populations. These populations collectively hold 182 plants in the islands of Puerto Rico, Culebra, and Vieques. Based on the IUCN Red List Criteria, E. fajardensis meets the requirements to be considered a Critically Endangered species.

TI Superovulatory response and embryo development in ewes treated with two doses of bovine somatotropin SO ANIMAL REPRODUCTION SCIENCE LA English DT Article DE Embryo transfer; Ewe; Somatotropin; Insulin; IGF-1 ID GROWTH-FACTOR-I; FACTOR SYSTEM RESPONSES; LACTATING DAIRY-COWS; PREGNANCY RATES; ESTROUS SYNCHRONIZATION; FOLLICLE DEVELOPMENT; OVARIAN-FOLLICLES; DOWN-REGULATION; OOCYTE QUALITY; LUTEAL-PHASE AB This study evaluated whether the administration of 50 and 100mg bovine somatotropin (bST) at the start of synchronization and at the time of natural mating in ewes improves the ovulation rate, embryonic development and pregnancy rate of transferred embryos. Forty-eight donors were assigned to three treatments: the bST-100 treatment (n = 15) received 100mg bST at the start of synchronization and at natural mating, the bST-50 treatment (n = 15) received 50mg bST on the same schedule as the previous group, and the control (n = 18) did not receive any bST. Two embryos were transferred to each recipient (n = 121): 35 received embryos from bST-100; 50 received embryos from bST-50, and 36 received embryos from the control. The superovulatory rate, percentage of recovered structures, cleavage rate, percentage of transferable embryos, embryo quality and development and pregnancy rate were analyzed using the GENMOD procedure of SAS. The number of corpora lutea and the cell number were analyzed using the GLM procedure of SAS. The insulin and IGF-1 concentrations were analyzed with ANOVA for repeated measures. The bST application did not affect the superovulatory rate, number of corpora lutea and recovered structures (P > 0.05). The numbers of transferable embryos and embryos reaching the blastocyst were higher (P <= 0.01) in the bST-50 (96.4 +/- 3.6% and 69.0 +/- 7.8%) than the bST-100 (93.0 +/- 4.5% and 27.2 +/- 38.9%) and control (87.7 +/- 5.4% and 50.4 +/- 6.4%) groups. The insulin and IGF-1 concentrations were higher (P < 0.05) in the bST-treated groups, but the insulin concentration was higher (P < 0.05) in the bST-100 group than in the bST-50 group. The pregnancy rate was similar (P = 0.21) in ewes receiving embryos from the two treatments [bST-50, (70.0%); bST-100, (62.5%), and control, (56.6%)]. The administration of 50mg bST at the start of synchronization and at natural mating in superovulated ewes was concluded to enhance the proportion and development of transferable embryos. However, bST did not affect the pregnancy rate of transferred embryos. (C) 2014 Published by Elsevier B.V. C1 [Carrera-Chavez, J. M.; Lopez-Carlos, M. A.; Lozano-Dominguez, R.

TI Cost-effective targeting of conservation investments to reduce the northern Gulf of Mexico hypoxic zone SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE eutrophication; hypoxic zone; Gulf of Mexico; agricultural conservation practices; evolutionary computation ID WATER-QUALITY; OPTIMIZATION; POLLUTION; SCALE; RIVER AB A seasonally occurring summer hypoxic (low oxygen) zone in the northern Gulf of Mexico is the second largest in the world. Reductions in nutrients from agricultural cropland in its watershed are needed to reduce the hypoxic zone size to the national policy goal of 5,000 km(2) (as a 5-y running average) set by the national Gulf of Mexico Task Force's Action Plan. We develop an integrated assessment model linking the water quality effects of cropland conservation investment decisions on the more than 550 agricultural subwatersheds that deliver nutrients into the Gulf with a hypoxic zone model. We use this integrated assessment model to identify the most cost-effective subwatersheds to target for cropland conservation investments. We consider targeting of the location (which subwatersheds to treat) and the extent of conservation investment to undertake (how much cropland within a subwatershed to treat). We use process models to simulate the dynamics of the effects of cropland conservation investments on nutrient delivery to the Gulf and use an evolutionary algorithm to solve the optimization problem. Model results suggest that by targeting cropland conservation investments to the most cost-effective location and extent of coverage, the Action Plan goal of 5,000 km(2) can be achieved at a cost of $2.7 billion annually. A large set of cost-hypoxia tradeoffs is developed, ranging from the baseline to the nontargeted adoption of the most aggressive cropland conservation investments in all subwatersheds (estimated to reduce the hypoxic zone to less than 3,000 km(2) at a cost of $5.6 billion annually).

A major role of T3SEs is to suppress plant immune responses and promote bacterial infection. The YopJ/HopZ acetyltransferases are a superfamily of T3SEs found in both plant and animal pathogenic bacteria. In P. syringae, this superfamily includes the evolutionarily diverse HopZ1, HopZ2 and HopZ3 alleles. To investigate the roles of the HopZ family in immunomodulation, we generated dexamethasone-inducible T3SE transgenic lines of Arabidopsis for HopZ family members and characterized them for immune suppression phenotypes. We show that all of the HopZ family members can actively suppress various facets of Arabidopsis immunity in a catalytic residuedependent manner. HopZ family members can differentially suppress the activation of mitogen-activated protein (MAP) kinase cascades or the production of reactive oxygen species, whereas all members can promote the growth of non-virulent P. syringae. Localization studies show that four of the HopZ family members containing predicted myristoylation sites are localized to the vicinity of the plasma membrane while HopZ3 which lacks the myristoylation site is at least partially nuclear localized, suggesting diversification of immunosuppressive mechanisms. Overall, we demonstrate that despite significant evolutionary diversification, all HopZ family members can suppress immunity in Arabidopsis. C1 [Lewis, Jennifer D.; Wilton, Mike; Mott, G.

Models indicate that warming from carbon emissions associated with land cover conversion has been partially offset by cooling from elevated albedo, but considerable uncertainty remains partly because of uncertainty in model treatments of albedo. This study incorporates a new spatially and temporally explicit, land cover specific albedo product derived from Moderate Resolution Imaging Spectroradiometer with a historical land use data set (Land Use Harmonization product) to provide more precise, observationally derived estimates of albedo impacts from anthropogenic land cover change with a complete range of data set specific uncertainty. The mean annual global albedo increase due to land cover change during 1700-2005 was estimated as 0.001060.00008 (meanstandard deviation), mainly driven by snow exposure due to land cover transitions from natural vegetation to agriculture. This translates to a top-of-atmosphere radiative cooling of -0.150.1Wm(-2) (meanstandard deviation). Our estimate was in the middle of the Intergovernmental Panel on Climate Change Fifth Assessment Report range of -0.05 to -0.25Wm(-2) and incorporates variability in albedo within land cover classes.

Genotypes to Soil Water Deficit SO PLOS ONE LA English DT Article ID 2 CONTRASTING POPULATIONS; DROUGHT-STRESS; OXIDATIVE STRESS; ENVIRONMENTAL-STRESSES; SIGNAL-TRANSDUCTION; ADAPTIVE RESPONSES; GROWTH-RESPONSES; GENE-EXPRESSION; LEAF-AREA; PLANTS AB Six months-old seminal plants of 36 cacao genotypes grown under greenhouse conditions were subjected to two soil water regimes (control and drought) to assess, the effects of water deficit on growth, chemical composition and oxidative stress. In the control, soil moisture was maintained near field capacity with leaf water potentials (Psi WL) ranging from -0.1 to -0.5 MPa. In the drought treatment, the soil moisture was reduced gradually by withholding additional water until Psi WL reached values of between -2.0 to -2.5 MPa. The tolerant genotypes PS-1319, MO-20 and MA-15 recorded significant increases in guaiacol peroxidase activity reflecting a more efficient antioxidant metabolism. In relation to drought tolerance, the most important variables in the distinguishing contrasting groups were: total leaf area per plant; leaf, stem and total dry biomass; relative growth rate; plant shoot biomass and leaf content of N, Ca, and Mg. From the results of these analyses, six genotypes were selected with contrasting characteristics for tolerance to soil water deficit [CC-40, C. SUL-4 and SIC-2 (non-tolerant) and MA-15, MO-20, and PA-13 (tolerant)] for further assessment of the expression of genes NCED5, PP2C, psbA and psbO to water deficit. Increased expression of NCED5, PP2C, psbA and psbO genes were found for non-tolerant genotypes, while in the majority of tolerant genotypes there was repression of these genes, with the exception of PA-13 that showed an increased expression of psbA. Mutivariate analysis showed that growth variables, leaf and total dry biomass, relative growth rate as well as Mg content of the leaves were the most important factor in the classification of the genotypes as tolerant, moderately tolerant and sensitive to water deficit. Therefore these variables are reliable plant traits in the selection of plants tolerant to drought.

The spiroketal conophthorin is an important semiochemical produced by developing fungal spores. Spiroketals are also used as signals for scolytid communication. Plants and fungi are known to emit varying volatile profiles under biotic and abiotic stress. This paper reports distinctive temporal-volatile profiles from three abiotic treatments, room temperature (control), -15 degrees C (cold), and -15 degrees C to room temperature (shock), of cactus tissue plugs. Volatiles from the three treatments included monoterpenes from control plugs, compounds of varying classes and origin at later stages for cold plugs, and known semiochemicals, including spiroketals, at later stages for shock plugs. The results highlight several important findings: a unique tissue source of the spiroketals; abiotic cold-shock stress is indicated as the cause of spiroketal production; and, given previous findings of spirogenesis, fungal spore involvement is a probable biosynthetic origin of the spiroketals. These findings suggest an important role of fungal volatiles as signaling plant vulnerability to insects.

However, an antiserum was obtained having high specificity and affinity to p-nitrobenzoylated histamine (NPHA), which can be easily formed from reaction between histamine and p-nitrobenzoic acid N-hydroxysuccinimide ester (PNBA-OSu) under mild conditions. Based on rabbit polyclonal antibodies, a competitive indirect ELISA (ciELISA) for histamine determination in foods was developed. After ciELISA and derivatization optimization, the assay showed good sensitivity, with limits of detection of 1.8 mg/kg, 93.6 mu g/L, and 93.6 mu g/kg in fish, red wine, and yoghurt, respectively, with negligible cross-reactivity with related biogenic amines and amino acids. Average recovery of histamine in fortified food samples ranged from 80.9% to 110.1% with coefficients of variation below 16.3%. Good correlation between the ciELISA and liquid chromatography-tandem mass spectrometry was obtained for spiked food samples.

The results indicated that certain (Z)-isomers are favored thermodynamically and/or kinetically over their (all-E)-counterparts. The relative percentages of (5Z)-lycopene in either thermodynamic or kinetic equilibria were approximately 33%, and those of (all-E)-lycopene were only approximately 22%. Most strikingly (15Z)-phytoene was the major isomer (>90%) when the thermodynamic or the kinetic equilibria were reached. These observations can explain the high levels of lycopene (Z)-isomers found in humans and their rapid formations upon additions of oil to tomato products. In addition, the results can be useful to predict the isomeric forms of lycopene, phytoene, and phytofluene expected in foods as well as in plasma and tissues upon ingestion. In light of the data in the present study, the use of certain geometrical isomers of phytoene, phytofluene and lycopene on their own or as mixtures is recommended in future studies aimed at assessing their possible bioactivity.

Understanding how these competing factors influence a population is complex and difficult to study, but here we demonstrate the utility of using a stochastic projection matrix model and perturbation analysis to gain insight into this problem. We modeled a black bear population subjected to stochastic failures of fruiting and masting species, but with access to garbage in urban environments. We parameratized our model with data from a 6-year study on black bears in Aspen, Colorado and data synthesized from other research studies. Using computer simulation, we investigated the effect that different levels of conflict-bear removal can have on a bear population by comparing a "reference" scenario where bears did not benefit from human food sources or experience conflict-bear removals with two urban scenarios where bears had varying access to human foods, but conflict bears were removed. We used perturbation analyses to evaluate consequences for changing population vital rates and to estimate the impact each vital rate change had on population growth. Simulations were used to identify how much variation in each vital rate influenced variation in the population growth rate. We identified the survival rate of breeding adult females during good natural food years as having the highest elasticity value. We found that the benefit of increased cub production from available human food sources during natural food failure years was quickly negated if management of conflict bears through removal reduced adult female survival. Increasing the frequency of years when natural food production fails resulted in disproportionate impacts from available urban food and conflict-bear removals, where population growth rates in a High Removal scenario declined 1.5 times faster than in the reference scenario. Our findings suggest that for regions where changing climates will increase the frequency of natural food failures, managers may need to utilize non-lethal practices in managing conflict bears and municipalities will need to secure human food sources to reduce the need for conflict-bear removals and potential population declines.

Thermostable beta-xylosidases have been a focus of attention as industrially important enzymes due to their long shelf life and role in the relief of end-product inhibition of xylanases caused by xylo-oligosaccharides. Therefore, a highly thermostable beta-xylosidase with high specific activity has significant potential in lignocellulose bioconversion. Results: A gene encoding a highly thermostable GH39 beta-xylosidase was cloned from Geobacillus sp. strain WSUCF1 and expressed in Escherichia coli. Recombinant beta-xylosidase was active over a wide range of temperatures and pH with optimum temperature of 70 degrees C and pH 6.5. It exhibited very high thermostability, retaining 50% activity at 70 degrees C after 9 days. WSUCF1 beta-xylosidase is more thermostable than beta-xylosidases reported from other thermophiles (growth temperature <= 70 degrees C). Specific activity was 133 U/mg when incubated with p-nitrophenyl xylopyranoside, with K-m and V-max values of 2.38 mM and 147 U/mg, respectively. SDS-PAGE analysis indicated that the recombinant enzyme had a mass of 58 kDa, but omitting heating prior to electrophoresis increased the apparent mass to 230 kDa, suggesting the enzyme exists as a tetramer. Enzyme exhibited high tolerance to xylose, retained approximately 70% of relative activity at 210 mM xylose concentration. Thin layer chromatography showed that the enzyme had potential to convert xylo-oligomers (xylobiose, triose, tetraose, and pentaose) into fermentable xylose. WSUCF1 beta-xylosidase along with WSUCF1 endo-xylanase synergistically converted the xylan into fermentable xylose with more than 90% conversion. Conclusions: Properties of the WSUCF1 beta-xylosidase i.e. high tolerance to elevated temperatures, high specific activity, conversion of xylo-oligomers to xylose, and resistance to inhibition from xylose, make this enzyme potentially suitable for various biotechnological applications.

Using High-Resolution Melting SO PLOS ONE LA English DT Article ID ALBO-ATRUM; AUTOTETRAPLOID LUCERNE; VERTUS ALFALFA; LINKAGE MAPS; FORAGE YIELD; MODEL; MICROSATELLITE; MECHANISMS; TRUNCATULA; CULTIVARS AB Verticillium wilt, caused by the soilborne fungus, Verticillium alfalfae, is one of the most serious diseases of alfalfa (Medicago sativa L.) worldwide. To identify loci associated with resistance to Verticillium wilt, a bulk segregant analysis was conducted in susceptible or resistant pools constructed from 13 synthetic alfalfa populations, followed by association mapping in two F1 populations consisted of 352 individuals. Simple sequence repeat (SSR) and single nucleotide polymorphism (SNP) markers were used for genotyping. Phenotyping was done by manual inoculation of the pathogen to replicated cloned plants of each individual and disease severity was scored using a standard scale. Marker-trait association was analyzed by TASSEL. Seventeen SNP markers significantly associated with Verticillium wilt resistance were identified and they were located on chromosomes 1, 2, 4, 7 and 8. SNP markers identified on chromosomes 2, 4 and 7 co-locate with regions of Verticillium wilt resistance loci reported in M. truncatula. Additional markers identified on chromosomes 1 and 8 located the regions where no Verticillium resistance locus has been reported. This study highlights the value of SNP genotyping by high resolution melting to identify the disease resistance loci in tetraploid alfalfa. With further validation, the markers identified in this study could be used for improving resistance to Verticillium wilt in alfalfa breeding programs.

The new species causes flower galls on Camassia (Agavoideae; Asparagaceae) in the Pacific Northwest. Its current known distribution is Oregon and Washington, USA. Larvae develop in spring in flowers of Camassia spp., causing the young ovaries to enlarge prematurely and eventually abort, without forming seeds or mature fruit. Full-grown larvae crawl out of the gall in rapid succession and drop to the soil where they pupate; they remain there until spring of the following year when the adults emerge and lay eggs. The galls they induce in camas lily buds represent the first known association of the cosmopolitan genus Dasineura with the group of plants that includes Agave and its relatives.

Microarrays of neural tissue of animal models of the disease showed decreases in antioxidant genes, and increases in inflammatory genes. Cyclooxygenase (COX)-derived oxylipins are important mediators of inflammation. We measured oxylipin levels using tandem mass spectrometry and ELISAs in multiple cell and animal models of FRDA. Mass spectrometry revealed increases in concentrations of prostaglandins, thromboxane B2, 15-HETE and 11-HETE in cerebellar samples of knockin knockout mice. One possible explanation for the elevated oxylipins is that frataxin deficiency results in increased COX activity. While constitutive COX1 was unchanged, inducible COX2 expression was elevated over 1.35-fold (P<0.05) in two Friedreich's mouse models and Friedreich's lymphocytes. Consistent with higher COX2 expression, its activity was also increased by 58% over controls. COX2 expression is driven by multiple transcription factors, including activator protein 1 and cAMP response element-binding protein, both of which were elevated over 1.52-fold in cerebella. Taken together, the results support the hypothesis that reduced expression of frataxin leads to elevation of COX2-mediated oxylipin synthesis stimulated by increases in transcription factors that respond to increased reactive oxygen species. These findings support a neuroinflammatory mechanism in FRDA, which has both pathomechanistic and therapeutic implications.

Qi, Lu TI FTO genetic variants, dietary intake and body mass index: insights from 177 330 individuals SO HUMAN MOLECULAR GENETICS LA English DT Article ID OBESITY-ASSOCIATED GENE; TIME PHYSICAL-ACTIVITY; FAT MASS; ENERGY-INTAKE; FOOD-INTAKE; METABOLIC-RATE; ASSOCIATION; CHILDREN; RS9939609; GENOTYPE AB FTO is the strongest known genetic susceptibility locus for obesity. Experimental studies in animals suggest the potential roles of FTO in regulating food intake. The interactive relation among FTO variants, dietary intake and body mass index (BMI) is complex and results from previous often small-scale studies in humans are highly inconsistent. We performed large-scale analyses based on data from 177 330 adults (154 439 Whites, 5776 African Americans and 17 115 Asians) from 40 studies to examine: (i) the association between the FTO-rs9939609 variant (or a proxy single-nucleotide polymorphism) and total energy and macronutrient intake and (ii) the interaction between the FTO variant and dietary intake on BM I. The minor allele (A-allele) of the FTO-rs9939609 variant was associated with higher BMI in Whites (effect per allele = 0.34 [0.31, 0.37] kg/m(2), P = 1.9 x 10(-105)), and all participants (0.30 [0.30, 0.35] kg/m(2), P = 3.6 x 10(-107)). The BMI-increasing allele of the FTO variant showed a significant association with higher dietary protein intake (effect per allele = 0.08 [0.06, 0.10] %, P = 2.4 x 10(-16)), and relative weak associations with lower total energy intake (-6.4 [- 10.1, -2.6] kcal/day, P = 0.001) and lower dietary carbohydrate intake (-0.07 [- 0.11, -0.02] %, P = 0.004). The associations with protein (P = 7.5 x 10(-9)) and total energy (P = 0.002) were attenuated but remained significant after adjustment for BMI. We did not find significant interactions between the FTO variant and dietary intake of total energy, protein, carbohydrate or fat on BMI. Our findings suggest a positive association between the BMI-increasing allele of FTO variant and higher dietary protein intake and offer insight into potential link between FTO, dietary protein intake and adiposity.

Genome Are Enriched at Specific Locations in Thousands of Genes Coupled to Energy Status, Hypoxia, Low Sugar, and Nutrient Deprivation SO JOURNAL OF GENETICS AND GENOMICS LA English DT Article DE Maize; G-quadruplex; G4; Hypoxia; Sucrose synthase ID PROMOTER G-QUADRUPLEX; DNA G-QUADRUPLEXES; END RULE PATHWAY; ARABIDOPSIS-THALIANA; FORMING SEQUENCES; WIDE ANALYSIS; PROLYL HYDROXYLATION; NUCLEOTIDE-SEQUENCES; REGULATORY ELEMENTS; PROXIMAL PROMOTER AB The G-quadruplex (G4) elements comprise a class of nucleic acid structures formed by stacking of guanine base quartets in a quadruple helix. This G4 DNA can form within or across single-stranded DNA molecules and is mutually exclusive with duplex B-form DNA. The reversibility and structural diversity of G4s make them highly versatile genetic structures, as demonstrated by their roles in various functions including telomere metabolism, genome maintenance, immunoglobulin gene diversification, transcription, and translation. Sequence motifs capable of forming G4 DNA are typically located in telomere repeat DNA and other non-telomeric genomic loci. To investigate their potential roles in a large-genome model plant species, we computationally identified 149,988 non-telomeric G4 motifs in maize (Zea mays L., B73 AGPv2), 29% of which were in non-repetitive genomic regions. G4 motif hotspots exhibited non-random enrichment in genes at two locations on the antisense strand, one in the 50 UTR and the other at the 50 end of the first intron. Several genic G4 motifs were shown to adopt sequence-specific and potassium-dependent G4 DNA structures in vitro. The G4 motifs were prevalent in key regulatory genes associated with hypoxia (group VII ERFs), oxidative stress (DJ-1/GATase1), and energy status (AMPK/SnRK) pathways. They also showed statistical enrichment for genes in metabolic pathways that function in glycolysis, sugar degradation, inositol metabolism, and base excision repair. Collectively, the maize G4 motifs may represent conditional regulatory elements that can aid in energy status gene responses. Such a network of elements could provide a mechanistic basis for linking energy status signals to gene regulation in maize, a model genetic system and major world crop species for feed, food, and fuel.

SO PHYTOTAXA LA English DT Article DE Gomphillaceae; Graphis; Ocellularia; Thelotremataceae ID ASCOMYCOTA OSTROPALES GRAPHIDACEAE; LICHEN FAMILY THELOTREMATACEAE; TICOLICHEN BIODIVERSITY INVENTORY; TAKHTAJANS FLORISTIC REGIONS; CAPTURE PROBABILITIES VARY; GENUS GRAPHIS GRAPHIDACEAE; SOUTHEASTERN NORTH-AMERICA; WORLD-WIDE KEY; THELOTREMOID GRAPHIDACEAE; SOUTH-KOREA AB Recent studies of the global diversity of the lichenized fungal family Graphidaceae suggest that there are a large number of species remaining to be discovered. No less than 640 species have been described since 2002, including 175 new species introduced in a collaborative global effort in a single issue in this journal. These findings suggest that the largest family of tropical crustose lichens may have an even higher number of species than Parmeliaceae. To estimate whether the discovery of 175 new species is a significant step forward in cataloguing extant diversity in this family, we employed a parametric method to predict global species richness of Graphidaceae using a GIS-based grid map approach. The model employs linear regression between observed species richness and sample score and vegetation composition per grid to predict individual grid species richness, and interpolation of species grid distributions to predict global species richness. We also applied a non-parametric species-area curve approach and non-parametric species richness estimators (Chao, Jackknife, Bootstrap) to compare the results from the different methods. Our approach resulted in a prediction of 4,330 species of Graphidaceae, including approximately 3,500 (sub-) tropical species in the core subfamilies Fissurinoideae, Graphidoideae, Redonographoideae, plus 125 species restricted to extratropical regions (outside the zone between 30 degrees northern and 30 degrees southern latitude) and 700 species in subfamily Gomphilloideae. Currently, nearly 2,500 species are known in the family, including species not yet formally described. Thus, our model suggests that even after describing 175 species in this issue and with another approximately 140 awaiting publication, the number of species still to be discovered and described is more than 1,800, and much work remains to be done to close this substantial gap. Based on our approach, we predict that most of this undiscovered diversity is to be found in Mexico, the northern Andean region, the eastern Amazon and central and southern Brazil, tropical West Africa, continental Southeast Asia, Indonesia, and Papua New Guinea.

Based on the resulting topology, in addition to three tribes described previously, we recognize four further tribes in the subfamily Graphidoideae: Acanthothecieae Lumbsch, Kraichak & Lucking, Diploschisteae (Zahlbr.) Lumbsch, Kraichak & Lucking, Leptotremateae Lumbsch, Kraichak & Lucking, and Wirthiotremateae Lumbsch, Kraichak & Lucking. The phylogenetic position of Aggregatorygma and Borinquenotrema was not resolved with support, whereas Corticorygma forms part of Acanthothecieae, supported sister to Acanthothecis, and Paratopeliopsis belongs in Thelotremateae, unsupported sister to Leucodecton. Diorygma erythrellum is confirmed as a member of the Diorygma-Thalloloma clade, while Fissurina monilifera, inspite of its myriotremoid ascomata, belongs in Fissurina s.str. Redingeria dessiniana, although resembling the genus Phaeographopsis, is supported sister to R. glaucoglyphica. Topeliopsis darlingtonii forms the sister group to Gintarasia megalophthalma. Consequently, T. darlingtonii and the closely related T. elixii are recombined in Gintarasia as Gintarasia darlingtonii (Frisch & Kalb) Lumbsch, Kraichak & Lucking, and G. elixii (Frisch & Kalb) Lumbsch, Kraichak & Lucking.

Adding 165 newly generated sequences from the mitochondrial small subunit rDNA (mtSSU), the nuclear large subunit rDNA (nuLSU), and the second largest subunit of the DNA-directed RNA polymerase II (RPB2), we currently distinguish 218 species among the sequenced material, including the outgroup. This corresponds to almost half the species at this point recognized within this tribe. The newly generated sequences include 23 newly described species and one newly described genus published elsewhere in this volume. For the first time, Sarcographina cyclospora Mull. Arg., in spite of its distinctly lirellate ascomata, is shown to belong in tribe Ocellularieae, as strongly supported sister to Ocellularia inturgescens (Mull. Arg.) Mangold.

SO PHYTOTAXA LA English DT Article DE Caribbean; conservation ID ASCOMYCOTA OSTROPALES; THELOTREMOID GRAPHIDACEAE; AGARICALES HYGROPHORACEAE; FOREST; CLADE; KEY; DICTYONEMA; PHYLOGENY; HISTORY AB Two new genera and twelve new species of Graphidaceae are described from Puerto Rico. The two new genera, Borinquenotrema and Paratopeliopsis, are based on a combination of molecular sequence data and phenotype characters. Borinquenotrema, with the single new species B. soredicarpum, features rounded ascomata developing beneath and persistently covered with soralia and with an internal anatomy reminescent of Carbacanthographis; it is close to the tribe Ocellularieae. Paratopeliopsis, including the single new species P. caraibica, resembles a miniature Topeliopsis but differs in the distinctly farinose thallus and the small, brown ascospores; it is not closely related to the latter genus but belongs in tribe Thelotremateae. The other ten new species belong in the genera Acanthotrema, Clandestinotrema, Compositrema, Fissurina, Ocellularia, and Thalloloma. Acanthotrema alboisidiatum is closely related to A. brasilianum but differs in the short, white isidia resembling insect eggs. Clandestinotrema portoricense has a unique ascospore type with a longitudinal septum only in the proximal cell. Compositrema borinquense resembles a species of Stegobolus but belongs in Compositrema based on sequence data, and is characterized by ascomata with a unique columella composed of thick, irregularly radiating strands. The second new species in this genus, C. isidiofarinosum, differs by its ecorticate, farinose thallus with scattered, corticate isidia and by its small ascomata with inconspicuous columella. The three new species of Fissurina all have 3-septate ascospores and are otherwise characterized by an isidiate thallus and stellate, orange-yellow lirellae (F. aurantiacostellata), a verrucose thallus strongly encrusted with calcium oxalate crystals and white, irregularly branched lirellae (F. crystallifera), and myriotremoid ascomata arranged in short lines (F. monilifera). Ocellularia portoricensis belongs in the core group of Ocellularia and differs from O. cavata in the white medulla and the larger ascospores becoming brown, whereas O. vulcanisorediata produces prominent soralia and immersed ascomata with apically carbonized excipulum and columella and small, transversely septate, hyaline ascospores; it is closely related to O. conformalis. Finally, Thalloloma rubromarginatum resembles T. haemographum in the brownish lirellae with bright red margin but differs from that and other species in the corticate thallus and the norstictic acid chemistry. The new combination Ampliotrema rimosum (Hale) Mercado-Diaz, Lucking & Parnmen is also proposed. Considering the current biodiversity knowledge on this family, the high level of endemism observed in other groups of organisms in the island, and the relatively high number of Graphidaceae described, it is highly likely that at least some of these new taxa are endemic to the island. This view is further supported by the unique features of several of the new species, representing novel characters in the corresponding genera.

TI Western Spruce Budworm Outbreaks Did Not Increase Fire Risk over the Last Three Centuries: A Dendrochronological Analysis of Inter-Disturbance Synergism SO PLOS ONE LA English DT Article ID MOUNTAIN PINE-BEETLE; TREE-RING RECONSTRUCTION; ACTIVE CROWN FIRE; SUB-ALPINE FOREST; BRITISH-COLUMBIA; LODGEPOLE PINE; ROCKY-MOUNTAINS; UNITED-STATES; NORTH-AMERICA; PACIFIC-NORTHWEST AB Insect outbreaks are often assumed to increase the severity or probability of fire occurrence through increased fuel availability, while fires may in turn alter susceptibility of forests to subsequent insect outbreaks through changes in the spatial distribution of suitable host trees. However, little is actually known about the potential synergisms between these natural disturbances. Assessing inter-disturbance synergism is challenging due to the short length of historical records and the confounding influences of land use and climate changes on natural disturbance dynamics. We used dendrochronological methods to reconstruct defoliator outbreaks and fire occurrence at ten sites along a longitudinal transect running from central Oregon to western Montana. We assessed synergism between disturbance types, analyzed long-term changes in disturbance dynamics, and compared these disturbance histories with dendroclimatological moisture availability records to quantify the influence of moisture availability on disturbances. After approximately 1890, fires were largely absent and defoliator outbreaks became longer-lasting, more frequent, and more synchronous at our sites. Fires were more likely to occur during warm-dry years, while outbreaks were most likely to begin near the end of warm-dry periods. Our results show no discernible impact of defoliation events on subsequent fire risk. Any effect from the addition of fuels during defoliation events appears to be too small to detect given the overriding influence of climatic variability. We therefore propose that if there is any relationship between the two disturbances, it is a subtle synergistic relationship wherein climate determines the probability of occurrence of each disturbance type, and each disturbance type damps the severity, but does not alter the probability of occurrence, of the other disturbance type over long time scales. Although both disturbance types may increase in frequency or extent in response to future warming, our records show no precedent that western spruce budworm outbreaks will increase future fire risk.

In this paper, we developed a high-density 3D TiO2 fiber-nanorod (NR) heterostructure for efficient photoelectrochemical (PEC) water splitting. The hierarchical structure was synthesized on a ZnO-coated cellulose nanofiber (CNF) template using atomic layer deposition (ALD)-based thin film and NR growth procedures. The tubular structure evolution was in good agreement with the recently discovered vapor-phase Kirkendall effect in high-temperature ALD processes. The NR morphology was formed via the surface-reaction-limited pulsed chemical vapor deposition (SPCVD) mechanism. Under Xenon lamp illumination without and with an AM 1.5G filter or a UV cut off filter, the PEC efficiencies of a 3D TiO2 fiber-NR heterostructure were found to be 22-249% higher than those of the TiO2-ZnO bilayer tubular nanofibers and TiO2 nanotube networks that were synthesized as reference samples. Such a 3D TiO2 fiber-NR heterostructure offers a new route for a cellulose-based nanomanufacturing technique, which can be used for large-area, low-cost, and green fabrication of nanomaterials as well as their utilizations for efficient solar energy harvesting and conversion.

Data was obtained over a 5-year study period (2009-2013) from two freshwater marsh sites located in Everglades National Park that differ in hydrology. At the short-hydroperiod site (Taylor Slough; TS) and the long-hydroperiod site (Shark River Slough; SRS) fluctuations in precipitation patterns occurred with changes in ENSO phase, suggesting that extreme ENSO phases alter Everglades hydrology which is known to have a substantial influence on ecosystem carbon dynamics. Variations in both ENSO phase and annual net CO2 exchange rates co-occurred with changes in wet and dry season length and intensity. Combined with site-specific seasonality in CO2 exchanges rates, El Nino and La Nina phases magnified season intensity and CO2 exchange rates at both sites. At TS, net CO2 uptake rates were higher in the dry season, whereas SRS had greater rates of carbon sequestration during the wet season. As La Nina phases were concurrent with drought years and extended dry seasons, TS became a greater sink for CO2 on an annual basis (-11 to -110 g CO2 m(-2) yr(-1)) compared to El Nino and neutral years (-5 to -43.5 g CO2 m(-2) yr(-1)). SRS was a small source for CO2 annually (1.81 to 80 g CO2 m(-2) yr(-1)) except in one exceptionally wet year that was associated with an El Nino phase (-16 g CO2 m(-2) yr(-1)). Considering that future climate predictions suggest a higher frequency and intensity in El Nino and La Nina phases, these results indicate that changes in extreme ENSO phases will significantly alter CO2 dynamics in the Florida Everglades.

No taxonomic description was provided, as adult specimens were not examined. Methods: Lungworm specimens were collected in the terminal bronchioles of muskoxen from Quebec, and a woodland caribou from central Alberta, Canada. The L3 stage was recovered from experimentally infected slugs (Deroceras spp.). Description of specimens was based on comparative morphology and integrated approaches. Molecular identity was determined by PCR and sequencing of the ITS-2 region of the nuclear ribosomal DNA, and compared to other protostrongylids. Results: Varestrongylus eleguneniensis sp. n. is established for a recently discovered protostrongylid nematode found in caribou (Rangifer tarandus), muskoxen (Ovibos moschatus) and moose (Alces americanus); hosts that collectively occupy an extensive geographic range across northern North America. Adults of Varestrongylus eleguneniensis are distinguished from congeners by a combination of characters in males (distally bifurcate gubernaculum, relatively short equal spicules not split distally, a strongly elongate and bifurcate dorsal ray, and an undivided copulatory bursa) and females (reduced provagina with hood-like fold extending ventrally across prominent genital protuberance). Third-stage larvae resemble those found among other species in the genus. The genus Varestrongylus is emended to account for the structure of the dorsal ray characteristic of V. eleguneniensis, V. alpenae, V. alces and V. longispiculatus. Conclusions: Herein we describe and name V. eleguneniensis, a pulmonary protostrongylid with Rangifer tarandus as a primary definitive host, and which secondarily infects muskoxen and moose in areas of sympatry. Biogeographic history for V. eleguneniensis and V. alpenae, the only two endemic species of Varestrongylus known from North America, appears consistent with independent events of geographic expansion with cervid hosts from Eurasia into North America during the late Pliocene and Quaternary.

Identification of repeats is important not only because it improves gene prediction, but also because of the role that repetitive sequences play in determining the structure and evolution of genes and genomes. Several methods using different repeat-finding strategies are available for whole-genome repeat sequence analysis. Four independent approaches were used to identify and characterize the repetitive fraction of the Mycosphaerella graminicola (synonym Zymoseptoria tritici) genome. This ascomycete fungus is a wheat pathogen and its finished genome comprises 21 chromosomes, eight of which can be lost with no obvious effects on fitness so are dispensable. Results: Using a combination of four repeat-finding methods, at least 17% of the M. graminicola genome was estimated to be repetitive. Class I transposable elements, that amplify via an RNA intermediate, account for about 70% of the total repetitive content in the M. graminicola genome. The dispensable chromosomes had a higher percentage of repetitive elements as compared to the core chromosomes. Distribution of repeats across the chromosomes also varied, with at least six chromosomes showing a non-random distribution of repetitive elements. Repeat families showed transition mutations and a CpA -> TpA dinucleotide bias, indicating the presence of a repeat-induced point mutation (RIP)-like mechanism in M. graminicola. One gene family and two repeat families specific to subtelomeres also were identified in the M. graminicola genome. A total of 78 putative clusters of nested elements was found in the M. graminicola genome. Several genes with putative roles in pathogenicity were found associated with these nested repeat clusters. This analysis of the transposable element content in the finished M. graminicola genome resulted in a thorough and highly curated database of repetitive sequences. Conclusions: This comprehensive analysis will serve as a scaffold to address additional biological questions regarding the origin and fate of transposable elements in fungi. Future analyses of the distribution of repetitive sequences in M. graminicola also will be able to provide insights into the association of repeats with genes and their potential role in gene and genome evolution.

Methods: Specimens used in the redescription were collected from lesions in the lungs of Eurasian moose, from Vestby, Norway. Specimens were described based on comparative morphology and integrated approaches. Molecular identification was based on PCR, cloning and sequencing of the ITS-2 region of the nuclear ribosomal DNA. Phylogenetic analysis compared Varestrongylus alces ITS-2 sequences to these of other Varestrongylus species and other protostrongylids. Results: Varestrongylus alces is resurrected for protostrongylid nematodes of Eurasian moose from Europe. Varestrongylus alces causes firm nodular lesions that are clearly differentiated from the adjacent lung tissue. Histologically, lesions are restricted to the parenchyma with adult, egg and larval parasites surrounded by multinucleated giant cells, macrophages, eosinophilic granulocytes, lymphocytes. The species is valid and distinct from others referred to Varestrongylus, and should be separated from Varestrongylus capreoli. Morphologically, Varestrongylus alces can be distinguished from other species by characters in the males that include a distally bifurcated gubernaculum, arched denticulate crura, spicules that are equal in length and relatively short, and a dorsal ray that is elongate and bifurcated. Females have a well-developed provagina, and are very similar to those of Varestrongylus capreoli. Morphometrics of first-stage larvae largely overlap with those of other Varestrongylus. Sequences of the ITS-2 region strongly support mutual independence of Varestrongylus alces, Varestrongylus cf. capreoli, and the yet undescribed species of Varestrongylus from North American ungulates. These three taxa form a well-supported crown-clade as the putative sister of Varestrongylus alpenae. The association of Varestrongylus alces and Alces or its ancestors is discussed in light of host and parasite phylogeny and host historical biogeography. Conclusions: Varestrongylus alces is a valid species, and should be considered distinct from Varestrongylus capreoli. Phylogenetic relationships among Varestrongylus spp. from Eurasia and North America are complex and consistent with faunal assembly involving recurrent events of geographic expansion, host switching and subsequent speciation.

Here we use PPO RNAi transformants of red clover (Trifolium pratense) to determine the role PPO plays in normal development of plants, and especially in N-2-fixing nodules. In red clover, PPO was not essential for either growth or nodule production, or for nodule function in plants grown under optimal, N-free conditions. However, absence of PPO resulted in a more reduced environment in all tissues, as measured by redox potential, and caused subtle developmental changes in nodules. Leaves and, to a lesser extent nodules, lacking PPO tended to accumulate phenolic compounds. A comparison of nodules of two representative contrasting clones by microscopy revealed that nodules lacking PPO were morphologically and anatomically subtly altered, and that phenolics accumulated in different cells and tissues. Developing nodules lacking PPO were longer, and there were more cell layers within the squashed cell layer (SCL), but the walls of these cells were less thickened and the cells were less squashed. Within the N-2-fixing zone, bacteroids appeared more granular and were less tightly packed together, and were similar to developmentally compromised bacteroids elicited by catalase mutant rhizobia reported elsewhere C1 [Webb, K.

Previous studies with HZE particles, have shown that irradiation produces enhanced indices of oxidative stress and inflammation as well as altered neuronal function that are similar to those seen in aging. Feeding animals antioxidant-rich berry diets, specifically blueberries and strawberries, countered the deleterious effects of irradiation by reducing oxidative stress and inflammation, thereby improving neuronal signaling. In the current study, we examined the effects of exposure to Fe-56 particles in critical regions of brain involved in cognitive function, both 36 h and 30 days post irradiation. We also studied the effects of antioxidant-rich berry diets, specifically a 2% blueberry or strawberry diet, fed for 8 weeks prior to radiation as well as 30 days post irradiation. Fe-56 exposure caused significant differential, neurochemical changes in critical regions of the brain, such as hippocampus, striatum, frontal cortex, and cerebellum, through increased inflammation, and increased oxidative stress protein markers. Fe-56 exposure altered the autophagy markers, and antioxidant-rich berry diets significantly reduced the accumulation of p62 in hippocampus, a scaffold protein that co-localizes with ubiquitinated protein at the 30 days post irradiation time-point. Exposure to Fe-56 particles increased the accumulation of disease-related proteins such as PHF-tau in the hippocampus of animals fed the control diet, but not in the irradiated animals fed the blueberry diet. These results indicate the potential protective effects of antioxidant-rich berry diets on neuronal functioning following exposure to HZE particles. Published by Elsevier B.V.

Despite this, significant problems have arisen with the conservation of waterlogged wooden artifacts. Three major issues facing conservators are structural instability on drying, biological degradation, and chemical degradation on account of Fe3+- catalyzed production of sulfuric and oxalic acid in the waterlogged timbers. Currently, no conservation treatment exists that effectively addresses all three issues simultaneously. A new conservation treatment is reported here based on a supramolecular polymer network constructed from natural polymers with dynamic cross-linking formed by a combination of both host-guest complexation and a strong siderophore pendant from a polymer backbone. Consequently, the proposed consolidant has the ability to chelate and trap iron while enhancing structural stability. The incorporation of antibacterial moieties through a dynamic covalent linkage into the network provides the material with improved biological resistance. Exploiting an environmentally compatible natural material with completely reversible chemistries is a safer, greener alternative to current strategies and may extend the lifetime of many culturally relevant waterlogged artifacts around the world.

The cost of implementing the WIPs between 2011 and 2025 is estimated to be about $3.6 billion (in 2010 dollars). The annual cost associated with full implementation of all WIP BMPs from 2025 onward is about $900 million. Significant cost savings can be realized through careful and efficient BMP selection and spatial targeting. If retiring up to 25% of current agricultural land is included as an option, Bay-wide cost savings of about 60% could be realized compared to the WIPs.

TI A gene-derived SNP-based high resolution linkage map of carrot including the location of QTL conditioning root and leaf anthocyanin pigmentation SO BMC GENOMICS LA English DT Article DE Carrot; Anthocyanins; QTL mapping; Linkage map; Single nucleotide polymorphism ID CAROTA L. GENOME; DAUCUS-CAROTA; GENOTYPING ERRORS; SWEET-POTATO; BIOSYNTHESIS; EXPRESSION; MARKERS; PURPLE; BIOAVAILABILITY; PATHWAY AB Background: Purple carrots accumulate large quantities of anthocyanins in their roots and leaves. These flavonoid pigments possess antioxidant activity and are implicated in providing health benefits. Informative, saturated linkage maps associated with well characterized populations segregating for anthocyanin pigmentation have not been developed. To investigate the genetic architecture conditioning anthocyanin pigmentation we scored root color visually, quantified root anthocyanin pigments by high performance liquid chromatography in segregating F-2, F-3 and F-4 generations of a mapping population, mapped quantitative trait loci (QTL) onto a dense gene-derived single nucleotide polymorphism (SNP)-based linkage map, and performed comparative trait mapping with two unrelated populations. Results: Root pigmentation, scored visually as presence or absence of purple coloration, segregated in a pattern consistent with a two gene model in an F2, and progeny testing of F-3-F-4 families confirmed the proposed genetic model. Purple petiole pigmentation was conditioned by a single dominant gene that co-segregates with one of the genes conditioning root pigmentation. Root total pigment estimate (RTPE) was scored as the percentage of the root with purple color. All five anthocyanin glycosides previously reported in carrot, as well as RTPE, varied quantitatively in the F2 population. For the purpose of QTL analysis, a high resolution gene-derived SNP-based linkage map of carrot was constructed with 894 markers covering 635.1 cM with a 1.3 cM map resolution. A total of 15 significant QTL for all anthocyanin pigments and for RTPE mapped to six chromosomes. Eight QTL with the largest phenotypic effects mapped to two regions of chromosome 3 with co-localized QTL for several anthocyanin glycosides and for RTPE. A single dominant gene conditioning anthocyanin acylation was identified and mapped. Comparative mapping with two other carrot populations segregating for purple color indicated that carrot anthocyanin pigmentation is controlled by at least three genes, in contrast to monogenic control reported previously. Conclusions: This study generated the first high resolution gene-derived SNP-based linkage map in the Apiaceae. Two regions of chromosome 3 with co-localized QTL for all anthocyanin pigments and for RTPE, largely condition anthocyanin accumulation in carrot roots and leaves. Loci controlling root and petiole anthocyanin pigmentation differ across diverse carrot genetic backgrounds.

TI Placental accommodations for transport and metabolism during intra-uterine crowding in pigs SO JOURNAL OF ANIMAL SCIENCE AND BIOTECHNOLOGY LA English DT Review DE Glycosaminoglycans; Nutrient transport; Placenta ID AMINO-ACID TRANSPORTERS; FOLATE-BINDING-PROTEIN; UTERINE CAPACITY; OVULATION RATE; LITTER SIZE; FATTY-ACID; ZINC TRANSPORTER; IRON-METABOLISM; LATE-GESTATION; GRAVID UTERUS AB Litter size and birth weights are limited by uterine capacity, defined as the ability of the uterus to maintain the appropriate development of some number of conceptuses. Uterine capacity is the result of the combined effects of uterine, placental and embryo/fetal function. The number of living conceptuses that the uterus is capable of supporting is greater during early gestation compared to later gestation. Plots of log fetal weight versus log placental weight also indicate that fetal weights are less sensitive to reduced placental weight (and therefore reduced intrauterine space) in early gestation compared to late gestation. However, even in late gestation, mechanisms still exist that maintain fetal growth when the size of the placenta is reduced. One such mechanism is likely to be improved development of the folded placental-epithelial/maternal-epithelial bilayer. Fold depth, and therefore the maternal fetal interactive surface, increases as gestation advances and is greater in placenta from small fetuses. On the fetal side of the placenta, the epithelial bilayer is embedded in stromal tissue. Glycosaminoglycans are major components of stroma, including hyaluronan and heparan sulfate. Hyaluronidases and heparanases are present within placental tissues, and likely play roles in modification of stromal components to facilitate fold development. Glycosaminoglycans are polymers of forms of glucose (glucosamine, glucuronic acid, iduronic acid) suggesting that glycosaminoglycan synthesis may compete with the glucose needs of the developing fetus. Pig conceptuses are fructogenic, such that a substantial portion of glucose transferred from mother to fetus is converted to fructose. Fructose is an intermediate product in the synthesis of glucosamine from glucose, and glucosamine is linked to regulation of trophoblast cell proliferation through regulation of mTOR. These findings suggest a link between glucose, fructose, glucosamine synthesis, GAG production, and placental morphogenesis, but the details of these interactions remain unclear. In addition, recent placental epithelial transcriptome analysis identified several glucose, amino acid, lipid, vitamin, mineral and hormone transporter mechanisms within the placenta. Further elucidation of mechanisms of placental morphogenesis and solute transport could provide clues to improving nutrient transport to the pig fetus, potentially increasing litter size and piglet birth weights.

In the first experiment the sheep grazed I. asanfolia in the field while in the second, sheep were maintained in individual bays consuming dry I. asarifolia at 10% and 20% into their ration. In both experiments the lambs remained confined, consuming only their mother's milk. Four of 8 lambs in the grazing experiment and the 4 nursing lambs from the ewes given 20% L asarifolia showed signs of L asarifolia poisoning. These results confirm that the tremorgenic compound of L asarifolia or its toxic metabolites are eliminated in milk and can intoxicate nursing lambs. (C) 2014 Elsevier Ltd. All rights reserved.

TI Microclimate through space and time: Microclimatic variation at the edge of regeneration forests over daily, yearly and decadal time scales SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Disturbance; Edge effects; Forest influence; Microclimate; Recolonisation; Variable retention ID DOUGLAS-FIR FORESTS; CLEAR-CUT EDGES; VARIABLE RETENTION; SOIL-MOISTURE; RAIN-FOREST; ECOLOGICAL BOUNDARIES; VEGETATION RESPONSES; WESTERN-AUSTRALIA; SPATIAL-PATTERNS; TEMPERATURE AB A major aim of sustainable forest management is the maintenance or recolonisation of harvested areas by species that were present pre-disturbance. Forest influence (a type of edge effect that focuses on the effect of mature forests on adjacent disturbed forest) is considered to be an important factor that contributes to the ability of mature forest species to re-colonise disturbed areas. Forest influence occurs in two main ways by: (1) by providing a source of propagules or individuals for recolonisation; and (2) by its influence on the biotic and abiotic conditions of the disturbed forest. This study focuses on forest influence's impact on microclimate conditions of adjacent disturbed areas regenerating after harvesting. In particular, the study investigates whether microclimate within a regenerating forest changes with increasing distance from a mature forest edge, and whether the magnitude of microclimatic change varies over diurnal, seasonal and successional time scales. Results of the study showed that the microclimate of regenerating forests is affected by the distance to a standing mature forest. Temperature, relative humidity, vapour pressure deficit, and the short-term fluctuations of these microclimate parameters were influenced by nearby mature forest. In addition, the study found that the magnitude of forest influence changes over diurnal, seasonal and successional time scales. For example, it was discovered that forest influence is greatest during the middle of the day, during the summer months when solar heating is greatest and on hot windy days. Critically; the impact of forest influence peaked around 27 years after disturbance in the areas studied, with less influence shortly after disturbance. We speculate this is due to lower levels of midday shading in the 7 year old forest. Forest influence on microclimate persisted in regeneration areas that were harvested 45 years ago, although the magnitude and importance of the effect was low. We conclude that proximity to mature forest stands (forests influence) impacts the microclimate of forests regenerating after disturbance, although the response is quite variable through time. Our results provide insight into the role of microclimate on the ability of mature forest species to successfully recolonise after disturbance. Management practices, such as aggregated retention and other forms of retention forestry, which increase the proportion of harvested area under forest influence, may provide a mechanism to promote the re-colonisation of mature-forest species.

TI Local and general above-stump biomass functions for loblolly pine and slash pine trees SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Pinus taeda; Pinus elliottii; Above ground allometry; Carbon stock modeling ID SOUTHERN UNITED-STATES; ESTIMATING FOREST BIOMASS; RADIATION-USE EFFICIENCY; BELOW-GROUND BIOMASS; UPPER COASTAL-PLAIN; ABOVEGROUND BIOMASS; STAND DEVELOPMENT; LEAF-AREA; GROWTH EFFICIENCY; ELLIOTTII STANDS AB There is an increasing interest in estimating biomass for loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm. var. elliottii), two of the most ecologically and commercially important tree species in North America. The majority of the available individual-tree allometric models are local, relying on stem diameter outside bark at breast height (dbh) and, in some cases, total tree height (H): only a few include stand age or other covariates. Using a large dataset collected from five forestry research institutions in the southeastern U.S., consisting of biomass measurements from 744 loblolly pine and 259 slash pine trees, we developed a set of individual-tree equations to predict total tree above-stump biomass, stem biomass outside bark, live branch biomass and live foliage biomass, as well as functions to determine stem bark fraction in order to calculate stem wood biomass inside bark and stem bark biomass from stem biomass outside bark determinations. Local and general models are presented for each tree attribute. Local models included dbh or dbh and H as predicting variables. General models included stand-level variables such as age, quadratic mean diameter, basal area and stand density. This paper reports the first set of local and general allometric equations reported for loblolly and slash pine trees. The models can be applied to trees growing over a large geographical area and across a wide range of ages and stand characteristics. These sets of equations provide a valuable alternative to available models and are intended as a tool to support present and future management decisions for the species, allowing for a variety of ecological, silvicultural and economic applications, as regional assessments of stand biomass or estimating ecosystem C balance.

TI Mountain pine beetle-caused mortality over eight years in two pine hosts in mixed-conifer stands of the southern Rocky Mountains SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Forest disturbance; Dendroctonus ponderosae; Host selection; Hopkins' Host Selection Principle; Lodgepole pine; Ponderosa pine ID WESTERN UNITED-STATES; COLORADO FRONT RANGE; SPATIOTEMPORAL PATTERNS; TREE MORTALITY; LODGEPOLE PINE; PONDEROSA PINE; CLIMATE-CHANGE; BOREAL FOREST; BARK BEETLES; EXPANSION AB Eruptive mountain pine beetle (Dendroctonus ponderosae, MPB) populations have caused widespread mortality of pines throughout western North America since the late 1990s. Early work by AD. Hopkins suggested that when alternate host species are available, MPB will prefer to breed in the host to which it has become adapted. In Colorado, epidemic MPB populations that originated in lodgepole pine expanded into mixed-conifer stands containing ponderosa pine, a related host. We evaluated the susceptibility of both hosts to successful MPB colonization in a survey of 19 sites in pine-dominated mixed-conifer stands spanning 140 km of the Front Range, CO, USA. In each of three 0.2-ha plots at each site, we (1) assessed trees in the annual flights of 2008-2011 to compare MPB-caused mortality between lodgepole and ponderosa pine; (2) recorded previous MPB-caused tree mortality from 2004-2007 to establish baseline mortality levels; and (3) measured characteristics of the stands (e.g. tree basal area) and sites (e.g. elevation, aspect) that might be correlated with MPB colonization. Uninfested average live basal area of lodgepole and ponderosa pine was 74% of total basal area before 2004. We found that for both species, annual percent basal area of attacked trees was greatest in one year (2009), and was lower in all other years (2004-2007, 2008, 2010, and 2011). Both pine species had similar average total mortality of 38-39% by 2011. Significant predictors of ponderosa pine mortality in a given year were basal area of uninfested ponderosa pine and the previous year's mortality levels in both ponderosa and lodgepole pine. Lodgepole pine mortality was predicted by uninfested basal areas of both lodgepole and ponderosa pine, and the previous year's lodgepole pine mortality. These results indicate host selection by MPB from lodgepole pine natal hosts into ponderosa pine the following year, but not the reverse. In both species, diameters of attacked trees within each year were similar, and were progressively smaller the last four years of the study period. Our results suggest that, in contrast to previous reports, ponderosa and lodgepole pine were equally susceptible to MPB infestation in the CO Front Range during our study period. This suggests that forest managers may anticipate similar impacts in both hosts during similar environmental conditions when epidemic-level MPB populations are active in mixed-pine stands.

TI Analyzing the transmission of wildfire exposure on a fire-prone landscape in Oregon, USA SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Wildfire simulation; Wildfire risk; Network analysis; Risk network; Forest fuel treatments ID FUEL TREATMENTS; WILDLAND FIRE; NETWORK ANALYSIS; SOCIAL NETWORKS; UNITED-STATES; RISK; FOREST; SIMULATION; CHALLENGES; MANAGEMENT AB We develop the idea of risk transmission from large wildfires and apply network analyses to understand its importance on a 0.75 million ha US national forest. Wildfires in the western US frequently burn over long distances (e.g., 20-50 km) through highly fragmented landscapes with respect to ownership, fuels, management intensity, population density, and ecological conditions. The collective arrangement of fuel loadings in concert with weather and suppression efforts ultimately determines containment and the resulting fire perimeter. While spatial interactions among land parcels in terms of fire spread and intensity have been frequently noted by fire managers, quantifying risk and exposure transmission has not been attempted. In this paper we used simulation modeling to quantify wildfire transmission and built a transmission network consisting of land designations defined by national forest management designations and ownership. We then examined how a forest-wide fuel management program might change the transmission network and associated metrics. The results indicated that the size, shape, and fuel loading of management designations affected their exposure to wildfire from other designations and ownerships. Manipulating the fuel loadings via simulated forest fuel treatments reduced the wildfire transmitted among the land designations, and changed the network density as well. We discuss how wildfire transmission has implications for creating fire adapted communities, conserving biodiversity, and resolving competing demands for fire-prone ecosystem services.

We found that ducks possess three different IL-2/15R beta transcripts, a conventional form (duIL-2/15R beta) and two variants. Comparisons between the cDNA and genomic sequences revealed that the two variants, duIL-2/15R beta-d7 and duIL-2/15R beta-d9, were novel spliced transcripts resulting from skipping exons 7 and 9, respectively. Expression profiles of duIL-2/15R beta and its isoforms were examined in healthy tissues, concanavalin A (ConA)-stimulated splenic lymphocytes and in livers and spleens of Riemerella anatipestifer-infected ducks using quantitative realtime PCR (qRT-PCR). Generally, duIL-2/15R beta-d9 expression was undetectable in healthy tissues, ConA-activated samples, and R. anatipestifer-infected ducks. Expression levels of duIL-2/15R beta transcript were relatively high to moderate in all healthy tissues tested, while duIL-2/15R13-d7 expression was low. Compared to untreated controls, expression levels of duIL-2/15R beta were elevated in ConA-activated splenic lymphocytes and in livers on day 7 in R. anatipestifer-infected ducks, while duIL-2/15R beta-d7 expression was unchanged. Additionally, COS-7 cells transfected with duIL-2/15R beta, duIL-2/15R beta-d7, or duIL-2/15R beta-d9 constructs generated 73 kilodalton (kDa), 31 kDa, and 40 kDa proteins, respectively. This study identified three different IL-2/15R beta transcripts, including two isoforms generated by alternative splicing and their gene expression patterns in stimulated conditions.

Broiler eggs were injected with either 100 mu l of PBS alone (BT0), or 20 or 40 mu g/egg of BT in PBS (BT20, BT40) at 18 days of embryogenesis. On day 14 post-hatch, the chickens were uninfected or orally infected with 1.0 x 10(4) oocysts of Eimeria maxima (E. maxima). On day 18 post-hatch, E. maxima-infected chickens were orally infected with 1.0 x 10(9) CFU of Clostridium perfringens (C perfringens). Compared with untreated and infected BT0 controls, BT20 and/or BT40 birds showed increased body weights, decreased fecal shedding of E. maxima oocysts, lower serum a-toxin and NetB levels, increased levels of serum antibodies against C. perfringens a-toxin and NetB toxin, decreased levels of serum malondialdehyde, reduced serum catalase and superoxide dismutase catalytic activities, and increased intestinal levels of gene transcripts encoding interleukin (IL)-1 beta, IL-6, IL-8, and peroxiredoxin-6, but decreased levels of transcripts for catalase and glutathione peroxidase. Interestingly, transcript levels for inducible nitric oxide synthase and paraoxonase/arylesterase 2 were decreased in the BT20 group and increased in the BT40 group, compared with BT0 controls. These results indicate that in ova administration of broiler chickens with a Se-containing protein hydrolysate enhanced protection against experimental NE possibly by altering the expression of proinflammatory and anti-oxidant genes and their downstream pathways.

TI A rapid method for determining salinomycin and monensin sensitivity in Eimeria tenella SO VETERINARY PARASITOLOGY LA English DT Article DE Eimeria; lonophore; Culture; PCR; Drug sensitivity ID ANTICOCCIDIAL DRUGS; RESISTANCE; COCCIDIOSIS; FOWL; STRATEGIES; CHICKEN AB Standard methods of determining the ionophore sensitivity of Eimeria rely on infecting chickens with an isolate or a mixture of Eimeria spp. oocysts in the presence of different anti-coccidial drugs. The purpose of this study was to develop a rapid in vitro method for assessing salinomycin and monensin sensitivity in Eimeria tenella. Cultures of MDBK cells were grown to 85% confluency, and then inoculated with excysted E. tenella laboratory strain (APU-1) sporozoites in the presence of different concentrations of salinomycin or monensin. At various timepoints, the monolayers were fixed for counting intraceullar sporozoites, or were subjected to DNA extraction, followed by molecular analysis using quantitative (qPCR) or semi-quantitative PCR (sqPCR). Preliminary experiments showed that 24 h was the optimum time for harvesting the E. tene/la-infected cell cultures. The average number of E. tenella sporozoites relative to untreated controls displayed a linear decrease between 03 and 33.0 mu g/ml alinomycin and between 0.3 and 3.3 mu g/ml monensin. A similar pattern was observed in the relative amount of E. tenella DNA as measured by sqPCR. A linear decrease in the relative amount of E. tenella DNA was observed over the entire range of salinomycin and monensin concentrations as measured by qPCR possibly reflecting the greater sensitivity of this assay. Comparison of sporozoite counting, sqPCR, and qPCR signals using a criterion of 50% inhibition in sporozoite numbers or level of PCR amplification product showed good agreement between the three assays. E. tenella field isolates (FS-1 and FS-2) displaying resistance to salinomycin and monensin were evaluated in the in vitro assay using qPCR and sqPCR. Compared to E. tenella APU-1, the E. tenella FS-1 and FS-2 isolates showed higher levels of E. tenella DNA at 24 h by both qPCR and sciPCR. This in vitro assay represents a significant advance in developing rapid, cost-effective methods for assessing ionophore sensitivity in E. tenella. Published by Elsevier B.V. C1 [Jenkins, M.

TI Seroepidemiology of Toxoplasma gondii infection in bats from Sao Paulo city, Brazil SO VETERINARY PARASITOLOGY LA English DT Article DE Bats; Brazil; Serological survey; Toxoplasma gondii; Zoonoses; Wildlife ID PREVALENCE AB Toxoplasmosis is a parasitic zoonosis caused by Toxoplasma gondii protozoan with a worldwide distribution. The aim of this study was to determine the frequency of IgG anti-T. gondii antibodies in bats from Sao Paulo city, Brazil. A total of 616 serum samples were collected from 22 species of bats. Anti-T. gondii antibodies were searched using the indirect fluorescent antibody test (IFAT >= 1:16) and IgG anti-bat antibodies produced in sheep on samples collected during 2006-2011; 32.62% (201/616) of bats had T. gondii antibodies. The modified agglutination test (MAT >= 1:25) was performed on samples collected during 2010-2011; 18.61% (35/188) were seropositive. The concordance between IFAT and MAT (serum samples from 2010 to 2011) by Kappa (95% CI) was 0.144, resulting in a low agreement between the techniques. The specificity and sensitivity of MAT and IFAT have not been evaluated for the diagnosis of toxoplasmosis in bats. Thus, it was verified that bats are exposed to T. gondii during their lifetime and they are also part of the toxoplasmosis epidemiology. (C) 2014 Elsevier B.V. All rights reserved.

The incidence is highest in infants and relates to preterm birth, necrotizing enterocolitis, atresia, gastroschisis, volvulus, and aganglionosis. Patient outcomes have improved, but there is a need to develop new therapies for SBS and to understand intestinal adaptation after different diseases, resection types, and nutritional and pharmacological interventions. Animal studies are needed to carefully evaluate the cellular mechanisms, safety, and translational relevance of new procedures. Distal intestinal resection, without a functioning colon, results in the most severe complications and adaptation may depend on the age at resection (preterm, term, young, adult). Clinically relevant therapies have recently been suggested from studies in preterm and term PN-dependent SBS piglets, with or without a functional colon. Studies in rats and mice have specifically addressed the fundamental physiological processes underlying adaptation at the cellular level, such as regulation of mucosal proliferation, apoptosis, transport, and digestive enzyme expression, and easily allow exogenous or genetic manipulation of growth factors and their receptors (e.g., glucagon-like peptide 2, growth hormone, insulin-like growth factor 1, epidermal growth factor, keratinocyte growth factor). The greater size of rats, and especially young pigs, is an advantage for testing surgical procedures and nutritional interventions (e.g., PN, milk diets, long-/short-chain lipids, pre- and probiotics). Conversely, newborn pigs (preterm or term) and weanling rats provide better insights into the developmental aspects of treatment for SBS in infants owing to their immature intestines. The review shows that a balance among practical, economical, experimental, and ethical constraints will determine the choice of SBS model for each clinical or basic research question.

Changing climate is likely to alter the ecohydrology and other ecosystem processes, which affect forest structures and functions. We constructed a multi-year water budget (2004-2010) and quantified environmental controls on an evapotranspiration (ET) in a 70-year-old mixed-oak woodland forest in northwest Ohio, USA. ET was measured using the eddy-covariance technique along with precipitation (P), soil volumetric water content (VWC), and shallow groundwater table fluctuation. Three biophysical models were constructed and validated to calculate potential ET (PET) for developing predictive monthly ET models. We found that the annual variability in ET was relatively stable and ranged from 578mm in 2009 to 670mm in 2010. In contrast, ET/P was more variable and ranged from 0.60 in 2006 to 0.96 in 2010. Mean annual ET/PET_FAO was 0.64, whereas the mean annual PET_FAO/P was 1.15. Annual ET/PET_FAO was relatively stable and ranged from 0.60 in 2005 to 0.72 in 2004. Soil water storage and shallow groundwater recharge during the non-growing season were essential in supplying ET during the growing season when ET exceeded P. Spring leaf area index (LAI), summer photosynthetically active radiation, and autumn and winter air temperatures (T-a) were the most significant controls of monthly ET. Moreover, LAI regulated ET during the whole growing season and higher temperatures increased ET even during dry periods. Our empirical modelling showed that the interaction of LAI and PET explained >90% of the variability in measured ET. Altogether, we found that increases in T-a and shifts in P distribution are likely to impact forest hydrology by altering shallow groundwater fluctuations, soil water storage, and ET and, consequently, alter the ecosystem functions of temperate forests.

The forest experienced defoliation by Gypsy moth (Lymantria dispar L.) in 2007, drought conditions in 2006 and a more severe drought in 2010. By using sap flux and eddy covariance measurements, stream discharge data from USGS, soil water changes, precipitation (P) and precipitation throughfall, a local water balance was derived. Average annual canopy transpiration (EC) during 2005-2011 was 201 mm a(-1) +/- 47 mm a(-1). A defoliation event reduced EC by 20% in 2007 compared with the 2005-2011 mean. During drought years in 2006 and 2010, stand transpiration was reduced by 8% in July 2006 and by 18% in 2010, respectively, compared with the overall July average. During July 2007, after the defoliation and subsequent reflushing of half of the leaves, E-C was reduced by 25%. This stand may experience higher sensitivity to drought when recovering from a defoliation event as evidenced by the higher reduction of EC in 2010 (post-defoliation) compared with 2006 (pre-defoliation). Stream water discharge was normalized to the watershed area by dividing outflow with the watershed area. It showed the greatest correlation with transpiration for time lags of 24 days and 219 days, suggesting hydrological connectivity on the watershed scale; stream water discharge increases when transpiration decreases, coinciding with leaf-on and leaf-off conditions. Thus, any changes in transpiration or precipitation will also alter stream water discharge and therefore water availability. Under future climate change, frequency and intensity of precipitation and episodic defoliation events may alter local water balance components in this upland oak/pine forest.

Optical absorption and emission, computational structure optimization, and cyclic voltammetry studies were systematically performed to establish the role of each entity in the multistep photochemical reactions. The energy-level diagram established from optical and redox data helped identifying different photochemical events. Selective excitation of BODIPY resulted in efficient singlet energy transfer to the ZnP entity. Ultrafast electron transfer from the (ZnP)-Zn-1* (formed either as a result of singletsinglet energy transfer or direct excitation) or C-1(60)* of the coordinated fullerene resulting into the formation of the Fc-(C-60(-) Im: ZnPC+)-BODIPY radical ion pair was witnessed by femtosecond transient absorption studies. Subsequent hole migration to the ferrocene entity resulted in the Fc(+)-(C-60(+) Im: ZnP)-BODIPY radical ion pair that persisted for 7-15 ms, depending upon the solvent conditions and contributions from the triplet excited states of ZnP and ImC(60), as revealed by the nanosecond transient spectral studies. Better utilization of light energy in generating the long-lived charge-separated state with the help of the present "antenna- reaction-center" model system has been successfully demonstrated.

Rates of trichinellosis have declined significantly in the United States due to improved pork production practices and public awareness of the danger of eating raw or undercooked pork. In April 2011, the Minnesota Department of Health received a report of presumptive trichinellosis in a 50-year-old man with a history of wild boar consumption. A public health investigation was initiated. Methods. Medical record reviews and patient and family interviews were conducted. Trichinella species serology was performed on patient and family serum samples, and larval identification was attempted on clinical specimens and meat samples. Results. The index patient harvested a wild boar from an Iowa game farm; he processed the meat after returning home and developed gastrointestinal symptoms 2 days later. Four days after his illness onset, all 5 family members consumed a roast from the boar. The index patient sought healthcare 4 times after illness onset before being definitively diagnosed with trichinellosis. Following initiation of albendazole therapy, the index patient developed atrial fibrillation. One additional family member who processed the raw meat was diagnosed with trichinellosis. Trichinella spiralis larvae were identified in wild boar meat samples. Conclusions. Trichinellosis has long been recognized as a potential hazard of consuming undercooked wild carnivore meat, and historically has been associated with consumption of pork from domestic swine, but may be unfamiliar to practicing clinicians in the United States. Education of hunters and the broader population on the potential for trichinellosis and the importance of proper handling and cooking meat from wild or free-range animals needs to be reinforced.

Acidification has been linked with reduced fitness and richness of aquatic species and changes to benthic communities. Maintaining acid-base chemistry that supports native biota depends largely on balancing acidic deposition with the natural resupply of base cations. Stream water acid neutralizing capacity (ANC) is maintained by base cations that mostly originate from weathering of surrounding lithologies. When ambient atmospheric S deposition exceeds the critical load (CL) an ecosystem can tolerate, stream water chemistry may become lethal to biota. This work links statistical predictions of ANC and base cation weathering for streams and watersheds of the SAM region with a steady-state model to estimate CLs and exceedances. Results showed that 20.1% of the total length of study region streams displayed ANC <100 mu eq.L-1, a level at which effects to biota may be anticipated; most were 4th or lower order streams. Nearly one-third of the stream length within the study region exhibited CLs of S deposition <50 meq.m(-2).yr(-1), which is less than the regional average S deposition of 60 meq.m(-2).yr(-1). Owing to their geologic substrates, relatively high elevation, and cool and moist forested conditions, the percentage of stream length in exceedance was highest for mountain wilderness areas and in national parks, and lowest for privately owned valley bottom land. Exceedance results were summarized by 12-digit hydrologic unit code (subwatershed) for use in developing management goals and policy objectives, and for long-term monitoring. (C) 2014 Elsevier Ltd.

Here we examined the effects of Se treatment on the accumulation of anticancer compound Se-methylselenocysteine (SeMSCys) and glucosinolates in Brassica sprouts. Cultivars from the six most extensively consumed Brassica vegetables (broccoli, cauliflower, green cabbage, Chinese cabbage, kale, and Brussels sprouts) were used. We found that Se-biofortified Brassica sprouts all were able to synthesize significant amounts of SeMSCys. Analysis of glucosinolate profiles revealed that each Brassica crop accumulated different types and amounts of glucosinolates. Cauliflower sprouts had high total glucosinolate content. Broccoli sprouts contained high levels of glucoraphanin, a precursor for potent anticancer compound. Although studies have reported an inverse relationship between accumulation of Se and glucosinolates in mature Brassica plants, Se supply generally did not affect glucosinolate accumulation in Brassica sprouts. Thus, Brassica vegetable sprouts can be biofortified with Se for the accumulation of SeMSCys without negative effects on chemopreventive glucosinolate contents. Published by Elsevier Ltd.

TI Changes in leukocyte subsets of pregnant gilts experimentally infected with porcine reproductive and respiratory syndrome virus and relationships with viral load and fetal outcome SO VETERINARY RESEARCH LA English DT Article ID T-CELL SUBSETS; ALVEOLAR MACROPHAGES; PERIPHERAL-BLOOD; IMMUNE-RESPONSES; SWINE-FEVER; PIGS; APOPTOSIS; IDENTIFICATION; PATHOGENESIS; LYMPHOCYTES AB In spite of more than two decades of extensive research, the understanding of porcine reproductive and respiratory syndrome virus (PRRSv) immunity is still incomplete. A PRRSv infection of the late term pregnant female can result in abortions, early farrowings, fetal death, and the birth of weak, congenitally infected piglets. The objectives of the present study were to investigate changes in peripheral blood mononuclear cell populations in third trimester pregnant females infected with type 2 PRRSv (NVSL 97-7895) and to analyze potential relationships with viral load and fetal mortality rate. PRRSv infection caused a massive, acute drop in total leukocyte counts affecting all PBMC populations by two days post infection. Except for B cells, cell counts started to rebound by day six post infection. Our data also show a greater decrease of naive B cells, T-helper cells and cytolytic T cells than their respective effector or memory counterparts. Absolute numbers of T cells and gamma delta T cells were negatively associated with PRRSv RNA concentration in gilt serum over time. Additionally, absolute numbers of T helper cells may be predictive of fetal mortality rate. The preceding three leukocyte populations may therefore be predictive of PRRSv-related pathological outcomes in pregnant gilts. Although many questions regarding the immune responses remain unanswered, these findings provide insight and clues that may help reduce the impact of PRRSv in pregnant gilts.

It is not known whether adolescent girls can make these adaptations during pregnancy. The present study aimed to measure and compare the protein, glutamine and alanine kinetics of adult women and adolescent girls at early-, mid-and late-pregnancy. Kinetics were measured in the overnight fasted state using intravenous infusions of C-13-leucine, N-15-glutamine and N-15-alanine in ten adults and twenty adolescents aged 14-17 years in the first and second trimesters (phase 1 study) and infusions of C-13-leucine and N-15(2)-urea in ten adults and eleven adolescents aged 16-17 years in the first and third trimesters (phase 2 study). In phase 1 study, there were no significant differences between the groups with regard to any of the kinetic parameters measured. In both groups, leucine flux increased (P<0.05), the percentage of leucine flux oxidised decreased (P<0.05) and non-oxidative leucine disposal to protein synthesis increased (P<0.05) from the first to the second trimester. In phase2 study, leucine flux was significantly slower (P<0.05) in the adult group than in the adolescent group during both trimesters, and whole-body leucine flux and non-oxidative leucine disposal increased significantly in the adolescent group (P<0.05, respectively) and were higher in the adult group from the first to the third trimester. These results suggest that similar to their adult counterparts after an overnight fast, adolescent girls with a normal BMI provide extra amino acids required for net protein deposition during pregnancy by increasing protein breakdown and decreasing amino acid oxidation.

TI solGS: a web-based tool for genomic selection SO BMC BIOINFORMATICS LA English DT Article DE Genomic selection; RR-BLUP; Bioinformatics; Database; Web-based tool ID BREEDING POPULATIONS; PREDICTION AB Background: Genomic selection (GS) promises to improve accuracy in estimating breeding values and genetic gain for quantitative traits compared to traditional breeding methods. Its reliance on high-throughput genome-wide markers and statistical complexity, however, is a serious challenge in data management, analysis, and sharing. A bioinformatics infrastructure for data storage and access, and user-friendly web-based tool for analysis and sharing output is needed to make GS more practical for breeders. Results: We have developed a web-based tool, called solGS, for predicting genomic estimated breeding values (GEBVs) of individuals, using a Ridge-Regression Best Linear Unbiased Predictor (RR-BLUP) model. It has an intuitive web-interface for selecting a training population for modeling and estimating genomic estimated breeding values of selection candidates. It estimates phenotypic correlation and heritability of traits and selection indices of individuals. Raw data is stored in a generic database schema, Chado Natural Diversity, co-developed by multiple database groups. Analysis output is graphically visualized and can be interactively explored online or downloaded in text format. An instance of its implementation can be accessed at the NEXTGEN Cassava breeding database, http://cassavabase.org/solgs. Conclusions: solGS enables breeders to store raw data and estimate GEBVs of individuals online, in an intuitive and interactive workflow. It can be adapted to any breeding program.

N. caninum is a major cause of abortion in cattle and dogs are main reservoirs because they excrete the environmentally resistant oocysts. Toxoplasmosis is a worldwide zoonosis and dogs are considered as sentinels for this parasite because of their close contact with people and cats; additionally dog meat is also used for human consumption in China. The aim of the present study was to assess the prevalence of N. caninum and T. gondii infection in dogs from China. A total of 425 countryside dog hearts in Jilin, Henan and Anhui provinces of the People's Republic of China were collected from slaughter houses in two batches; the first batch of 96 in October 2013, and the second batch of 329 in April 2014. Serum samples extracted from 96 dog hearts were tested for antibodies to N. caninum and from 425 dog hearts were tested for T. gondii antibodies in the modified agglutination tests (cut-off 1:25 for both), using respective antigens. Results: Antibodies to N. caninum were 6 of 96 (6.25%) of dogs with titers of 1:25 in 2, 1:50 in 3, and 1:100 in 1. All seropositive dogs were more than 1 year old. Antibodies to T. gondii were found in 35 of 425 (8.24%) dogs with titers of 1:25 in 15, 1:50 in 14; and 1:100 in 6. Conclusion: The results of the present study indicated low prevalence of N. caninum and T. gondii antibodies in dogs of China, compared with Europe and America. Identification of the risk factors that underlie these differences may help prevention of neosporosis and toxoplasmosis. This is the first report of N. caninum infection in dogs from China.

Nevertheless, the contributions of these apparent symbionts to digestive physiology and nutritional ecology remain uncharacterized in most beetle lineages. Results: Through parallel transcriptome profiling of beetle- and microbial-derived mRNAs, we demonstrate that the midgut microbiome of the Asian longhorned beetle (Anoplophora glabripennis), a member of the beetle family Cerambycidae, is enriched in biosynthetic pathways for the synthesis of essential amino acids, vitamins, and sterols. Consequently, the midgut microbiome of A. glabripennis can provide essential nutrients that the beetle cannot obtain from its woody diet or synthesize itself. The beetle gut microbiota also produce their own suite of transcripts that can enhance lignin degradation, degrade hemicellulose, and ferment xylose and wood sugars. An abundance of cellulases from several glycoside hydrolase families are expressed endogenously by A. glabripennis, as well as transcripts that allow the beetle to convert microbe-synthesized essential amino acids into non-essential amino acids. A. glabripennis and its gut microbes likely collaborate to digest carbohydrates and convert released sugars and amino acid intermediates into essential nutrients otherwise lacking from their woody host plants. Conclusions: The nutritional provisioning capabilities of the A. glabripennis gut microbiome may contribute to the beetles' unusually broad host range. The presence of some of the same microbes in the guts of other Cerambycidae and other wood-feeding beetles suggests that partnerships with microbes may be a facilitator of evolutionary radiations in beetles, as in certain other groups of insects, allowing access to novel food sources through enhanced nutritional provisioning.

Analyses control for female labor participation and metropolitan outlet densities that might affect body weight. Both the first-difference and fixed effects approaches provide consistent evidence suggesting that relative food prices have substantial impacts on obesity and such impacts were more pronounced among the low-educated. These findings imply that relative food price reductions during the time period could plausibly explain about 18% of the increase in obesity among the U.S. adults in metropolitan areas.

Several studies have suggested that behavior during the immature larval stages of Drosophila development is influenced by pheromones, but none of these compounds or the pheromone-receptor neurons that sense them have been identified. Here we report a larval pheromone-signaling pathway. We found that larvae produce two novel long-chain fatty acids that are attractive to other larvae. We identified a single larval chemosensory neuron that detects these molecules. Two members of the pickpocket family of DEG/ENaC channel subunits (ppk23 and ppk29) are required to respond to these pheromones. This pheromone system is evolving quickly, since the larval exudates of D. simulans, the sister species of D. melanogaster, are not attractive to other larvae. Our results define a new pheromone signaling system in Drosophila that shares characteristics with pheromone systems in a wide diversity of insects.

Using an experimental model of NE involving co-infection with C. perfringens and Eimeria maxima, transcriptome profiling and functional genomics approaches were applied to identify the genetic mechanisms that might regulate the host response to this disease. Microarray hybridization identified 1,049 transcripts whose levels were altered (601 increased, 448 decreased) in intestinal lymphocytes from C. perfringens/E. maxima co-infected Ross chickens compared with uninfected controls. Five biological functions, all related to host immunity and inflammation, and 11 pathways were identified from this dataset. To further elucidate the role of host genetics in NE susceptibility, two inbred chicken lines, ADOL line 6 and line 7 which share an identical B-2 major histocompatibility complex haplotype but differ in their susceptibility to virus infection, were compared for clinical symptoms and the expression levels of a panel of immune-related genes during experimental NE. Line 6 chickens were more susceptible to development of experimental NE compared with line 7, as revealed by decreased body weight gain and increased E. maxima oocyst shedding. Of 21 immune-related genes examined, 15 were increased in C. perfringens/E. maxima co-infected line 6 vs. line 7 chickens. These results suggest that immune pathways are activated in response to experimental NE infection and that genetic determinants outside of the chicken B complex influence resistance to this disease.

Here, we show that DGDG contributes to plant NO as well as salicylic acid biosynthesis and is required for the induction of systemic acquired resistance (SAR). In contrast, MGDG regulates the biosynthesis of the SAR signals azelaic acid (AzA) and glycerol-3-phosphate (G3P) that function downstream of NO. Interestingly, DGDG is also required for AzA-induced SAR, but MGDG is not. Notably, transgenic expression of a bacterial glucosyltransferase is unable to restore SAR in dgd1 plants even though it does rescue their morphological and fatty acid phenotypes. These results suggest that MGDG and DGDG are required at distinct steps and function exclusively in their individual roles during the induction of SAR.

AB Seed dormancy and resistance to decay are fundamental survival strategies, which allow a population of seeds to germinate over long periods of time. Seeds have physical, chemical, and biological defense mechanisms that protect their food reserves from decay-inducing organisms and herbivores. Here, we hypothesize that seeds also possess enzyme-based biochemical defenses, based on induction of the plant defense enzyme, polyphenol oxidase (PRO), when wild oat (Avena fatua L.) caryopses and seeds were challenged with seed-decaying Fusarium fungi. These studies suggest that dormant seeds are capable of mounting a defense response to pathogens. The pathogen-induced PRO activity from wild oat was attributed to a soluble isoform of the enzyme that appeared to result, at least in part, from proteolytic activation of a latent PRO isoform. PRO activity was also induced in wild oat hulls (lemma and palea), non-living tissues that cover and protect the caryopsis. These results are consistent with the hypothesis that seeds possess inducible enzyme-based biochemical defenses arrayed on the exterior of seeds and these defenses represent a fundamental mechanism of seed survival and longevity in the soil. Enzyme-based biochemical defenses may have broader implications since they may apply to other defense enzymes as well as to a diversity of plant species and ecosystems. C1 [Fuerst, E.

SO BMC GENETICS LA English DT Article DE Peanut; Genetic map; QTL analysis; Oil content; Oleic acid; Linoleic acid; O/L ratio; FAD2 genes ID HIGH OLEIC-ACID; HIGH OLEATE TRAIT; CULTIVATED PEANUT; LINKAGE MAP; REGISTRATION; PROFILES; POPULATIONS; RESISTANCE; STABILITY; GENOMICS AB Background: Peanut is one of the major source for human consumption worldwide and its seed contain approximately 50% oil. Improvement of oil content and quality traits (high oleic and low linoleic acid) in peanut could be accelerated by exploiting linked markers through molecular breeding. The objective of this study was to identify QTLs associated with oil content, and estimate relative contribution of FAD2 genes (ahFAD2A and ahFAD2B) to oil quality traits in two recombinant inbred line (RIL) populations. Results: Improved genetic linkage maps were developed for S-population (SunOleic 97R NC94022) with 206 (1780.6 cM) and T-population (Tifrunner GT-C20) with 378 (2487.4 cM) marker loci. A total of 6 and 9 QTLs controlling oil content were identified in the S and T population, respectively. The contribution of each QTL towards oil content variation ranged from 3.07 to 10.23% in the S-population and from 3.93 to 14.07% in the T-population. The mapping positions for ahFAD2A (A sub-genome) and ahFAD2B (B sub-genome) genes were assigned on a09 and b09 linkage groups. The ahFAD2B gene (26.54%, 25.59% and 41.02% PVE) had higher phenotypic effect on oleic acid (C18:1), linoleic acid (C18: 2), and oleic/linoleic acid ratio (O/L ratio) than ahFAD2A gene (8.08%, 6.86% and 3.78% PVE). The FAD2 genes had no effect on oil content. This study identified a total of 78 main-effect QTLs (M-QTLs) with up to 42.33% phenotypic variation (PVE) and 10 epistatic QTLs (E-QTLs) up to 3.31% PVE for oil content and quality traits. Conclusions: A total of 78 main-effect QTLs (M-QTLs) and 10 E-QTLs have been detected for oil content and oil quality traits. One major QTL (more than 10% PVE) was identified in both the populations for oil content with source alleles from NC94022 and GT-C20 parental genotypes. FAD2 genes showed high effect for oleic acid (C18: 1), linoleic acid (C18: 2), and O/L ratio while no effect on total oil content. The information on phenotypic effect of FAD2 genes for oleic acid, linoleic acid and O/L ratio, and oil content will be applied in breeding selection.

Previous expression of recombinant P. papatasi acetylcholinesterase (PpAChE1) revealed 85% amino acid sequence identity to mosquito AChE and identified synthetic carbamates that effectively inhibited PpAChE1 with improved specificity for arthropod AChEs compared to mammalian AChEs. We hypothesized that the G119S mutation causing high level resistance to organophosphate insecticides in mosquitoes may occur in PpAChE1 and may reduce sensitivity to inhibition. We report construction, expression, and biochemical properties of rPpAChE1 containing the G119S orthologous mutation. Methods: Targeted mutagenesis introduced the G119S orthologous substitution in PpAChE1 cDNA. Recombinant PpAChE1 enzymes containing or lacking the G119S mutation were expressed in the baculoviral system. Biochemical assays were conducted to determine altered catalytic properties and inhibitor sensitivity resulting from the G119S substitution. A molecular homology model was constructed to examine the modeled structural interference with docking of inhibitors of different classes. Genetic tests were conducted to determine if the G119S orthologous codon existed in polymorphic form in a laboratory colony of P. papatasi. Results: Recombinant PpAChE1 containing the G119S substitution exhibited altered biochemical properties, and reduced inhibition by compounds that bind to the acylation site on the enzyme (with the exception of eserine). Less resistance was directed against bivalent or peripheral site inhibitors, in good agreement with modeled inhibitor docking. Eserine appeared to be a special case capable of inhibition in the absence of covalent binding at the acylation site. Genetic tests did not detect the G119S mutation in a laboratory colony of P. papatasi but did reveal that the G119S codon existed in polymorphic form (GGA + GGC). Conclusions: The finding of G119S codon polymorphism in a laboratory colony of P. papatasi suggests that a single nucleotide transversion (GGC -> AGC) may readily occur, causing rapid development of resistance to organophosphate and phenyl- substituted carbamate insecticides under strong selection. Careful management of pesticide use in IPM programs is important to prevent or mitigate development and fixation of the G119S mutation in susceptible pest populations. Availability of recombinant AChEs enables identification of novel inhibitory ligands with improved efficacy and specificity for AChEs of arthropod pests.

TI High Amylose Resistant Starch Diet Ameliorates Oxidative Stress, Inflammation, and Progression of Chronic Kidney Disease SO PLOS ONE LA English DT Article ID GUT BACTERIAL TRANSLOCATION; EPITHELIAL TIGHT JUNCTION; IMPAIRS BARRIER FUNCTION; STAGE RENAL-DISEASE; CARBOHYDRATE AVAILABILITY; INTESTINAL MICROBIOTA; INDOLIC COMPOUNDS; UREMIA; MICROINFLAMMATION; MECHANISM AB Inflammation is a major mediator of CKD progression and is partly driven by altered gut microbiome and intestinal barrier disruption, events which are caused by: urea influx in the intestine resulting in dominance of urease-possessing bacteria; disruption of epithelial barrier by urea-derived ammonia leading to endotoxemia and bacterial translocation; and restriction of potassium-rich fruits and vegetables which are common sources of fermentable fiber. Restriction of these foods leads to depletion of bacteria that convert indigestible carbohydrates to short chain fatty acids which are important nutrients for colonocytes and regulatory T lymphocytes. We hypothesized that a high resistant starch diet attenuates CKD progression. Male Sprague Dawley rats were fed a chow containing 0.7% adenine for 2 weeks to induce CKD. Rats were then fed diets supplemented with amylopectin (low-fiber control) or high fermentable fiber (amylose maize resistant starch, HAM-RS2) for 3 weeks. CKD rats consuming low fiber diet exhibited reduced creatinine clearance, interstitial fibrosis, inflammation, tubular damage, activation of NF kappa B, upregulation of pro-inflammatory, pro-oxidant, and pro-fibrotic molecules; impaired Nrf2 activity, down-regulation of antioxidant enzymes, and disruption of colonic epithelial tight junction. The high resistant starch diet significantly attenuated these abnormalities. Thus high resistant starch diet retards CKD progression and attenuates oxidative stress and inflammation in rats. Future studies are needed to explore the impact of HAM-RS2 in CKD patients.

A problem of chemical treatments, however, is the potential for interaction of the active compound with the growth media substrate. We studied the interaction and efficacy of propiconazole, a potent and specific inhibitor of brassinosteroid biosynthesis, with common soilless greenhouse growth media for rice, sorghum, and maize. Many of the tested growth media interacted with propiconazole reducing its efficacy up to a hundred fold. To determine the molecular interaction of inhibitors with media substrates, Fourier Transform Infrared Spectroscopy and sorption isotherm analysis was applied. While mica clay substrates absorbed up to 1.3 mg of propiconazole per g substrate, calcined clays bound up to 12 mg of propiconazole per g substrate. The efficacy of the gibberellic acid biosynthesis inhibitor, uniconazole, and the most active brassinosteroid, brassinolide, was impacted similarly by the respective substrates. Conversely, gibberellic acid showed no distinct growth response in different media. Our results suggest that the reduction in efficacy of propiconazole, uniconazole, and brassinolide in bioassays when grown in calcined clay is caused by hydrophobic interactions between the plant growth regulators and the growth media. This was further confirmed by experiments using methanol-water solvent mixes with higher hydrophobicity values, which reduce the interaction of propiconazole and calcined clay.

TI Cytokine profiles in pregnant gilts experimentally infected with porcine reproductive and respiratory syndrome virus and relationships with viral load and fetal outcome SO VETERINARY RESEARCH LA English DT Article ID PLASMACYTOID DENDRITIC CELLS; IMMUNE-RESPONSES; PROINFLAMMATORY CYTOKINES; INTERLEUKIN-4 SUPPRESSES; PIGS; SWINE; EXPRESSION; GAMMA; VACCINATION; RECEPTOR AB In spite of extensive research, immunologic control mechanisms against Porcine Reproductive and Respiratory Syndrome virus (PRRSv) remain poorly understood. Cytokine responses have been exhaustively studied in nursery pigs and show contradictory results. Since no detailed reports on cytokine responses to PRRSv in pregnant females exist, the objectives of this study were to compare host cytokine responses between PRRSv-infected and non-infected pregnant gilts, and to investigate relationships between cytokine levels in infected gilts and viral load or fetal mortality rate. Serum samples and supernatants of peripheral blood mononuclear cells (PBMC) either stimulated with PRRSv or phorbol myristate acetate/Ionomycin (PMA/Iono) were analyzed for cytokines/chemokines: interleukins (IL) 1-beta (IL1 beta), IL4, IL8, IL10, IL12, chemokine ligand 2 (CCL2), interferon alpha (IFN alpha) and interferon gamma (IFN gamma). Three cytokines (IFN alpha, CCL2, IFN gamma) in gilt serum differed significantly in inoculated versus control gilts over time. In supernatants of PRRSv stimulated PBMC from PRRSv-infected gilts, levels of IFN alpha were significantly decreased, while IL8 secretion was significantly increased. PRRSv infection altered the secretion of all measured cytokines, with the exception of IFN alpha, from PBMC after mitogen stimulation, indicating a possible immunomodulatory effect of PRRSv. IFN alpha, CCL2, and IFN gamma in serum, and IFN gamma in supernatants of PMA/Iono stimulated PBMC were significantly associated with viral load in tissues, serum or both. However, only IFN alpha in supernatants of PRRSv stimulated PBMC was significantly associated with fetal mortality rate. We conclude that of the eight cytokines tested in this study IFN alpha was the best indicator of viral load and severity of reproductive PRRSv infection.

TI Genetic introgression of ethylene-suppressed transgenic tomatoes with higher-polyamines trait overcomes many unintended effects due to reduced ethylene on the primary rnetabolome SO FRONTIERS IN PLANT SCIENCE LA English DT Article DE ACC synthase; fruit ripening; LeACS2; metabolome; polyamines; spermidine; spermine; transgenics ID FRUIT-DEVELOPMENT; METABOLIC MEMORY; ANTISENSE GENE; BIOSYNTHESIS; REVEALS; QUALITY; PLANTS; TRANSCRIPT; RECEPTOR; JUICE AB Ethylene regulates a myriad physiological and biochemical processes in ripening fruits and is accepted as the ripening hormone for the climacteric fruits. However, its effects on metabolome and resulting fruit quality are not yet fully understood, particularly when some of the ripening-associated biochemical changes are independent of ethylene action. We have generated a homozygous transgenic tomato genotype (2AS-AS) that exhibits reduced ethylene production as a result of impaired expression of 1aminocyclopropane-1-carboxylate synthase 2 gene by its antisense RNA and had a longer shelf life. Double transgenic hybrid (2AS-AS x 579HO) developed through a genetic cross between 2AS-AS and 579HO (Mehta Mat, 2002) lines resulted in significantly higher ethylene production than either the WT or 2AS-AS fruit. To determine the effects of reduced ethylene and introgression of higher polyamines' trait, the metabolic profiles of ripening fruits from WT (556AZ), 2AS-AS, and 2AS-AS x 579HO lines were determined using 1H-NMR spectroscopy. The levels of Glu, Asp, AMP Adenosine, Nuc11, and Nucl2 increased during ripening of the WT fruit. The increases in Glu, Asp, and AMP levels were attenuated in 2AS-AS fruit but recovered in the double hybrid with higher ethylene and polyamine levels. The ripening-associated decreases in Ala, Tyr, Val, Ile, Phe, malate, and myo-inositol levels in the 2AS-AS line were not reversed in the double hybrid line suggesting a developmental/ripening regulated accumulation of these metabolites independent of ethylene. Significant increases in the levels of fumarate, formate, choline, Nuc11, and Nucl2 at most stages of ripening fruit were found in the double transgenic line due to introgression with higher-polyamines trait. Taken together these results show that the ripening-associated metabolic changes are both ethylene dependent and independent, and that the fruit metabolome is under the control of multiple regulators, including ethylene and polyamines.

Marker-assisted selection has proven to be an effective strategy in accelerating plant breeding for many plant species. Analysis of cymbidiums genetic background by molecular markers can be of great value in assisting parental selection and breeding strategy design, however, in plants such as cymbidiums limited genomic resources exist. In order to obtain efficient markers, we deep sequenced the C. ensifolium transcriptome to identify simple sequence repeats derived from gene regions (genic-SSR). Result: The 7,936 genic-SSR markers were identified. A total of 80 genic-SSRs were selected, and primers were designed according to their flanking sequences. Of the 80 genic-SSR primer sets, 62 were amplified in C. ensifolium successfully, and 55 showed polymorphism when cross-tested among 9 Cymbidium species comprising 59 accessions. Unigenes containing the 62 genic-SSRs were searched against Non-redundant (Nr), Gene Ontology database (GO), eukaryotic orthologous groups (KOGs) and Kyoto Encyclopedia of Genes and Genomes (KEGG) database. The search resulted in 53 matching Nr sequences, of which 39 had GO terms, 18 were assigned to KOGs, and 15 were annotated with KEGG. Genetic diversity and population structure were analyzed based on 55 polymorphic genic-SSR data among 59 accessions. The genetic distance averaged 0.3911, ranging from 0.016 to 0.618. The polymorphic index content (PIC) of 55 polymorphic markers averaged 0.407, ranging from 0.033 to 0.863. A model-based clustering analysis revealed that five genetic groups existed in the collection. Accessions from the same species were typically grouped together; however, C. goeringii accessions did not always form a separate cluster, suggesting that C. goeringii accessions were polyphyletic. Conclusion: The genic-SSR identified in this study constitute a set of markers that can be applied across multiple Cymbidium species and used for the evaluation of genetic relationships as well as qualitative and quantitative trait mapping studies. Genic-SSRs coupled with the functional annotations provided by the unigenes will aid in mapping candidate genes of specific function.

TI Limits on the reproducibility of marker associations with southern leaf blight resistance in the maize nested association mapping population SO BMC GENOMICS LA English DT Article DE Quantitative trait loci; Nested association mapping; Disease resistance; Genome wide association study; Zea mays ID QUANTITATIVE TRAIT LOCI; INBRED LINE POPULATIONS; GENOME-WIDE ASSOCIATION; GENETIC ARCHITECTURE; DISEASE RESISTANCE; INNATE IMMUNITY; FLOWERING TIME; SALICYLIC-ACID; JOINT ANALYSIS; ARABIDOPSIS AB Background: A previous study reported a comprehensive quantitative trait locus (QTL) and genome wide association study (GWAS) of southern leaf blight (SLB) resistance in the maize Nested Association Mapping (NAM) panel. Since that time, the genomic resources available for such analyses have improved substantially. An updated NAM genetic linkage map has a nearly six-fold greater marker density than the previous map and the combined SNPs and read-depth variants (RDVs) from maize HapMaps 1 and 2 provided 28.5 M genomic variants for association analysis, 17 fold more than HapMap 1. In addition, phenotypic values of the NAM RILs were re-estimated to account for environment-specific flowering time covariates and a small proportion of lines were dropped due to genotypic data quality problems. Comparisons of original and updated QTL and GWAS results confound the effects of linkage map density, GWAS marker density, population sample size, and phenotype estimates. Therefore, we evaluated the effects of changing each of these parameters individually and in combination to determine their relative impact on marker-trait associations in original and updated analyses. Results: Of the four parameters varied, map density caused the largest changes in QTL and GWAS results. The updated QTL model had better cross-validation prediction accuracy than the previous model. Whereas joint linkage QTL positions were relatively stable to input changes, the residual values derived from those QTL models (used as inputs to GWAS) were more sensitive, resulting in substantial differences between GWAS results. The updated NAM GWAS identified several candidate genes consistent with previous QTL fine-mapping results. Conclusions: The highly polygenic nature of resistance to SLB complicates the identification of causal genes. Joint linkage QTL are relatively stable to perturbations of data inputs, but their resolution is generally on the order of tens or more Mbp. GWAS associations have higher resolution, but lower power due to stringent thresholds designed to minimize false positive associations, resulting in variability of detection across studies. The updated higher density linkage map improves QTL estimation and, along with a much denser SNP HapMap, greatly increases the likelihood of detecting SNPs in linkage with causal variants. We recommend use of the updated genetic resources and results but emphasize the limited repeatability of small-effect associations.

TI Leaf litter decomposition rates increase with rising mean annual temperature in Hawaiian tropical montane wet forests SO PEERJ LA English DT Article DE Decomposition; Hawaii; Tropical wet forest; Climate change; Elevation gradient; Nitrogen cycling; Metrosideros polymorpha; Mean annual temperature (MAT); Leaf litter ID ORGANIC-MATTER; CARBON-DIOXIDE; STORAGE; METAANALYSIS; VARIABILITY; LIMITATION; DYNAMICS; GRADIENT; BALANCE; MODELS AB Decomposing litter in forest ecosystems supplies nutrients to plants, carbon to heterotrophic soil microorganisms and is a large source of CO2 to the atmosphere. Despite its essential role in carbon and nutrient cycling, the temperature sensitivity of leaf litter decay in tropical forest ecosystems remains poorly resolved, especially in tropical montane wet forests where the warming trend may be amplified compared to tropical wet forests at lower elevations. We quantified leaf litter decomposition rates along a highly constrained 5.2 degrees C mean annual temperature (MAT) gradient in tropical montane wet forests on the Island of Hawaii. Dominant vegetation, substrate type and age, soil moisture, and disturbance history are all nearly constant across this gradient, allowing us to isolate the effect of rising MAT on leaf litter decomposition and nutrient release. Leaf litter decomposition rates were a positive linear function of MAT, causing the residence time of leaf litter on the forest floor to decline by similar to 31 days for each 1 degrees C increase in MAT. Our estimate of the Q(10) temperature coefficient for leaf litter decomposition was 2.17, within the commonly reported range for heterotrophic organic matter decomposition (1.5-2.5) across a broad range of ecosystems. The percentage of leaf litter nitrogen (N) remaining after six months declined linearly with increasing MAT from similar to 88% of initial N at the coolest site to similar to 74% at the warmest site. The lack of net N immobilization during all three litter collection periods at all MAT plots indicates that N was not limiting to leaf litter decomposition, regardless of temperature. These results suggest that leaf litter decay in tropical montane wet forests may be more sensitive to rising MAT than in tropical lowland wet forests, and that increased rates of N release from decomposing litter could delay or prevent progressive N limitation to net primary productivity with climate warming.

In particular, they are important in ruminants where they digest a wide range of plant cell wall polysaccharides. For example, Ruminococcus albus 7 is a primary cellulose degrader that produces acetate usable by its bovine host. Moreover, it is one of the few organisms that ferments cellulose to form ethanol at mesophilic temperatures in vitro. The mechanism of cellulose degradation by R. albus 7 is not well-defined and is thought to involve pilin-like proteins, unique carbohydrate-binding domains, a glycocalyx, and cellulosomes. Here, we used a combination of comparative genomics, fermentation analyses, and transcriptomics to further clarify the cellulolytic and fermentative potential of R. albus 7. Results: A comparison of the R. albus 7 genome sequence against the genome sequences of related bacteria that either encode or do not encode cellulosomes revealed that R. albus 7 does not encode for most canonical cellulosomal components. Fermentation analysis of R. albus 7 revealed the ability to produce ethanol and acetate on a wide range of fibrous substrates in vitro. Global transcriptomic analysis of R. albus 7 grown at identical dilution rates on cellulose and cellobiose in a chemostat showed that this bacterium, when growing on cellulose, utilizes a carbohydrate-degrading strategy that involves increased transcription of the rare carbohydrate-binding module (CBM) family 37 domain and the tryptophan biosynthetic operon. Conclusions: Our data suggest that R. albus 7 does not use canonical cellulosomal components to degrade cellulose, but rather up-regulates the expression of CBM37-containing enzymes and tryptophan biosynthesis. This study contributes to a revised model of carbohydrate degradation by this key member of the rumen ecosystem.

Here, we present a comprehensive database named AIM for Arabidopsis (Arabidopsis thaliana) interactome modules. The database contains almost 250 000 modules that were generated using multiple analysis methods and integration of microarray expression data. All the modules in AIM are well annotated using multiple gene function knowledge databases. AIM provides a user-friendly interface for different types of searches and offers a powerful graphical viewer for displaying module networks linked to the enrichment annotation terms. Both interactive Venn diagram and power graph viewer are integrated into the database for easy comparison of modules. In addition, predicted interologs from other plant species (homologous proteins from different species that share a conserved interaction module) are available for each Arabidopsis module. AIM is a powerful systems biology platform for obtaining valuable insights into the function of proteins in Arabidopsis and other plants using the modules of the Arabidopsis interactome.

The present study investigated the effects of feedstock and temperature on characteristics of biochars and their adsorption ability for ammonium N (NH4+-N) and nitrate N (NO3--N). Twelve biochars were produced from wheat-straw (W-BC), corn-straw (C-BC) and peanut-shell (P-BC) at pyrolysis temperatures of 400, 500, 600 and 700 degrees C. Biochar physical and chemical properties were determined and the biochars were used for N sorption experiments. The results showed that biochar yield and contents of N, hydrogen and oxygen decreased as pyrolysis temperature increased from 400 degrees C to 700 degrees C, whereas contents of ash, pH and carbon increased with greater pyrolysis temperature. All biochars could sorb substantial amounts of NH4+-N, and the sorption characteristics were well fitted to the Freundlich isotherm model. The ability of biochars to adsorb NH4+-N followed: C-BC. P-BC. W-BC, and the adsorption amount decreased with higher pyrolysis temperature. The ability of C-BC to sorb NH4+-N was the highest because it had the largest cation exchange capacity (CEC) among all biochars (e.g., C-BC400 with a CEC of 38.3 cmol kg(-1) adsorbed 2.3 mg NH4+-N g(-1) in solutions with 50 mg NH4+ L-1). Compared with NH4+-N, none of NO3 -N was adsorbed to biochars at different NO3 concentrations. Instead, some NO3- -N was even released from the biochar materials. We conclude that biochars can be used under conditions where NH4+-N (or NH3) pollution is a concern, but further research is needed in terms of applying biochars to reduce NO3--N pollution.

TI Biopesticides: State of the Art and Future Opportunities SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article ID NATURAL-PRODUCTS; RNA INTERFERENCE; CROP PROTECTION; STRANDED-RNA; HERBICIDE; PESTICIDES; PLANTS; TOXAPHENE; DISCOVERY; IMPACT AB The use of biopesticides and related alternative management products is increasing. New tools, including semiochemicals and plant-incorporated protectants (PIPs), as well as botanical and microbially derived chemicals, are playing an increasing role in pest management, along with plant and animal genetics, biological control, cultural methods, and newer synthetics. The goal of this Perspective is to highlight promising new biopesticide research and development (R&D), based upon recently published work and that presented in the American Chemical Society (ACS) symposium Biopesticides: State of the Art and Future Opportunities, as well as the authors own perspectives. Although the focus is on biopesticides, included in this Perspective is progress with products exhibiting similar characteristics, namely those naturally occurring or derived from natural products. These are target specific, of low toxicity to nontarget organisms, reduced in persistence in the environment, and potentially usable in organic agriculture. Progress is being made, illustrated by the number of biopesticides and related products in the registration pipeline, yet major commercial opportunities exist for new bioherbicides and bionematicides, in part occasioned by the emergence of weeds resistant to glyphosate and the phase-out of methyl bromide. The emergence of entrepreneurial start-up companies, the U.S. Environmental Protection Agency (EPA) fast track for biopesticides, and the availability of funding for registration-related R&D for biorational pesticides through the U.S. IR-4 program provide incentives for biopesticide development, but an expanded effort is warranted both in the United States and worldwide to support this relatively nascent industry.

Seven accessions with different levels of oleic acid were selected from the entire USDA sesame germplasm collection (1232 accessions) and planted for morphological observation and re-examination of fatty acid composition. The coding region of the FAD2 gene for fatty acid desaturase (FAD) in these accessions was also sequenced. Cultivated sesame accessions flowered and matured earlier than the wild species. The cultivated sesame seeds contained a significantly higher percentage of oleic acid (40.4%) than the seeds of the wild species (26.1%). Nucleotide polymorphisms were identified in the FAD2 gene coding region between wild and cultivated species. Some nucleotide polymorphisms led to amino acid changes, one of which was located in the enzyme active site and may contribute to the altered fatty acid composition. Based on the morphology observation, chemical analysis, and sequence analysis, it was determined that two accessions were misnamed and need to be reclassified. The results obtained from this study are useful for sesame improvement in molecular breeding programs. C1 [Chen, Zhenbang] Univ Georgia, Dept Crop & Soil Sci, Griffin, GA 30223 USA.

Approximately 22% of the generated Cl-36-ClO2 was present on fumigated tomatoes after a 2 h exposure to approximately 5 mg of Cl-36-ClO2. A water rinse removed 14% of the radiochlorine while tomato homogenate contained similar to 63% of the tomato radioactivity; 24% of the radiochlorine was present in the tomato stem scar area. Radioactivity in tomato homogenate consisted of Cl-36-chloride (>= 80%), Cl-36-chlorate (5 to 19%), and perchlorate (0.5 to 1.4%). In cantaloupe, 55% of the generated Cl-36-ClO2 was present on melons fumigated with 100 mg of Cl-36-ClO2 for a 2 h period. Edible cantaloupe flesh contained no detectable radioactive residue (LOQ = 0.3 to 0.4 mu g/g); >99.9% of radioactivity associated with cantaloupe was on the inedible rind, with <0.1% associated with the seed bed. Rind radioactivity was present as Cl-36-chloride (similar to 86%), chlorate (similar to 13%), and perchlorate (similar to 0.6%). Absent from tomatoes and cantaloupe were Cl-36-chlorite residues. Follow-up studies have shown that chlorate and perchlorate formation can be completely eliminated by protecting fumigation chambers from light sources. C1 [Smith, D. J.; Giddings, J.

Saponin composition and content were varied according to tissues and accessions. The average total saponin concentration in 1 g mature dry seeds of wild soybean was 16.08 +/- 3.13 mu mol. In two-week-old seedlings, produced from 1 g mature seeds, it was 27.94 +/- 6.52 mu mol. Group A saponins were highly concentrated in seed hypocotyl (4.04 +/- 0.71 mu mol). High concentration of DDMP saponins (7.37 +/- 5.22 mu mol) and Sg-6 saponins (2.19 +/- 0.59 mu mol) was found in cotyledonary leaf. In seedlings, the amounts of group A and Sg-6 saponins reduced 2.3- and 1.3-folds, respectively, while DDMP + B + E saponins increased 2.5-fold than those of mature seeds. Our findings show that the group A and Sg-6 saponins in mature seeds were degraded and/or translocated by germination whereas DDMP saponins were newly synthesized.

However, the behavioral dimensions of ecosystem services and the responses of ordinary people to the management of those services, is less well understood. The ecosystem services framework lends itself to understanding the relationship between ecosystems and human behavior. Ecosystem services, according to the psychological theory of motivational functionalism, are motivations the personal and social processes that initiate, direct and sustain human action. Thus, how people perceive, acquire and use ecosystem services influences the initiation, direction, and intensity of their behaviors. Profound understanding of how people perceive, acquire and use ecosystem services can help influence behavioral compliance with management and policy prescriptions. We use focus group interviewing to illustrate how ecosystem services relate to human behavior. Results show that people perceive, acquire and use indirect benefits while acquiring direct ecosystem services. Understanding indirect benefits has implications for the constitution and regulation of human behavior through ecosystem management and policy. Perceived ecosystem benefits, expressed in people's own words and from their own frames of reference, can facilitate better valuation of ecosystem services and setting of prices, compliance with ecosystem management and policy directives, recruitment and retention of ecosystem stewards, development of use policies, enhancement of user experiences, and encouragement of pro environmental attitudes and behaviors.

New York City is one example where these groups have grown rapidly in number, size, and visibility since the 19705. In this article, we combine quantitative survey data with qualitative interview data to examine the structure and development of the governance network that has grown around the management of urban ecosystem services in New York City. We find that the network is organized according to ecological function and geography. We find as well, that certain historical conditions led to the development of a hybrid institutional form with regard to management of ecosystem services in the city. We discuss the implications of this hybrid networked governance structure in New York City and what it might mean for further cross-disciplinary research around ecosystem service governance.

TI Male-specific Y-linked transgene markers to enhance biologically-based control of the Mexican fruit fly, Anastrepha ludens (Diptera: Tephritidae) SO BMC GENETICS LA English DT Article ID GERM-LINE TRANSFORMATION; DROSOPHILA-MELANOGASTER; GENE-EXPRESSION; PIGGYBAC TRANSPOSON; CERATITIS-CAPITATA; SPERM MARKING; SEXING STRAIN; CHROMOSOME; PROMOTER; VECTOR AB Background: Reliable marking systems are critical to the prospective field release of transgenic insect strains. This is to unambiguously distinguish released insects from wild insects in the field that are collected in field traps, and tissue-specific markers, such as those that are sperm-specific, have particular uses such as identifying wild females that have mated with released males. For tephritid fruit flies such as the Mexican fruit fly, Anastrepha ludens, polyubiquitin-regulated fluorescent protein body markers allow transgenic fly identification, and fluorescent protein genes regulated by the spermatocyte-specific beta 2-tubulin promoter effectively mark sperm. For sterile male release programs, both marking systems can be made male-specific by linkage to the Y chromosome. Results: An A. ludens wild type strain was genetically transformed with a piggyBac vector, pBXL{PUbnlsEGFP, As beta 2tub-DsRed.T3}, having the polyubiquitin-regulated EGFP body marker, and the b2-tubulin-regulated DsRed. T3 sperm-specific marker. Autosomal insertion lines effectively expressed both markers, but a single Y-linked insertion (Y-EGFP strain) expressed only PUbnlsEGFP. This insertion was remobilized by transposase helper injection, which resulted in three new autosomal insertion lines that expressed both markers. This indicated that the original Y-linked As beta 2tub-DsRed. T3 marker was functional, but specifically suppressed on the Y chromosome. The PUbnlsEGFP marker remained effective however, and the Y-EGFP strain was used to create a sexing strain by translocating the wild type allele of the black pupae (bp(1)) gene onto the Y, which was then introduced into the bp(-) mutant strain. This allows the mechanical separation of mutant female black pupae from male brown pupae, that can be identified as adults by EGFP fluorescence. Conclusions: A Y-linked insertion of the pBXL{PUbnlsEGFP, As beta 2tub-DsRed. T3} transformation vector in A. ludens resulted in male-specific expression of the EGFP fluorescent protein marker, and was integrated into a black pupae translocation sexing strain (T(Y-EGFP/bp(+)), allowing the identification of male adults when used in sterile male release programs for population control. A unique observation was that expression of the As beta 2tub-DsRed. T3 sperm-specific marker, which was functional in autosomal insertions, was specifically suppressed in the Y-linked insertion. This may relate to the Y chromosomal regulation of male-specific germ-line genes in Drosophila.

TI Field Testing a Mobile Inelastic Neutron Scattering System to Measure Soil Carbon SO SOIL SCIENCE LA English DT Article DE Carbon; soil analysis; inelastic neutron scattering; thermo-neutron capture; neutron generator ID GAMMA-RAY SPECTROSCOPY; SPECTRA AB Cropping history in conjunction with soil management practices can have a major impact on the amount of organic carbon stored in soil. Current methods of assessing soil carbon based on soil coring and subsequent processing procedures before laboratory analysis are labor intensive and time-consuming. Development of alternative methods that can make in situ field measurements of soil carbon is needed to successfully evaluate management practices in a timely manner. The robust design, field testing procedure, and results of measuring soil carbon in situ using a mobile inelastic neutron scattering (MINS) system are described. A method of MINS spectra data processing that gives more accurate peak area determination compared with the traditional "trapezoidal" method is described. The MINS reliable autonomous operation for 29 h per charge cycle was demonstrated in the field. For comparison, soil cores were also collected for laboratory carbon analysis using the dry combustion technique. Soil carbon assessments by dry combustion technique and MINS demonstrated a linear correlation between the two methods in the 0- to 30-cm soil layer. Based on the developed theoretical model of MINS measurement, we demonstrated that accurate soil carbon determination by this method depends on carbon distribution within the soil and MINS signal errors.

The reactive surface functional groups on the humic materials were assumed to be a carboxyl site, XOH, and a phenol site, YOH. Initially, total concentrations of the sites, XOHT and YOHT and the proton dissociation constants for the carboxyl site, LogK(X-), and the phenol site, LogK(Y-), were optimized by fitting the constant capacitance model to potentiometric titration data on reference Aldrich humic acid obtained from the literature. Subsequently, the model was fit to experimental B adsorption data obtained from the literature by optimizing two tetrahedral B surface complexation constants: LogK(XB-) for a carboxyl site and LogK(YB-) for a phenol site. The model was well able to describe the experimental B adsorption data both as a function of solution B concentration (isotherm data) and solution pH (envelope data) for all humic materials. The ability to represent changes in B adsorption as a function of solution pH is the main advantage of the constant capacitance model over adsorption isotherm equations. Results from the current study can be used to describe B adsorption behavior on diverse humic materials of interest in environmental and agricultural situations.

Selenate adsorption decreased with increasing solution pH. The triple layer model, a chemical surface complexation model, was able to describe Se (VI) adsorption as a function of solution pH by simultaneously optimizing either two outer-sphere Se(VI) surface complexation constants or one inner-sphere and one outer-sphere Se(VI) surface complexation constant. The fit of the triple layer model to Se(VI) adsorption by oxides, clay minerals, and soils was excellent, as evidenced by very low values of the model variance goodness-of-fit criterion. The predominantly outer-sphere Se(VI) surface speciation predicted using the triple layer model was in agreement with the weak adsorption behavior previously observed for Se(VI) using electrophoretic mobility measurements and ionic strength dependence of adsorption. Direct spectroscopic investigations of Se(VI) surface configurations are needed to corroborate the species predicted by the triple layer modeling approach.

TI A minimally invasive method for sampling nest and roost cavities for fungi: a novel approach to identify the fungi associated with cavity-nesting birds SO ACTA ORNITHOLOGICA LA English DT Article DE Basidiomycota specific primer; cavity-excavating birds; cavity-nesting birds; excavators; fungi; hole-nesting birds; ITS4b-21; Picoides borealis; Porodaedalea pini; Red-cockaded Woodpecker; wood decay fungi ID RED-COCKADED WOODPECKER; NORTH-AMERICA; TREES; DECAY; SELECTION; FORESTS AB Relationships among cavity-nesting birds, trees, and wood decay fungi pose interesting management challenges and research questions in many systems. Ornithologists need to understand the relationships between cavity-nesting birds and fungi in order to understand the habitat requirements of these birds. Typically, researchers rely on fruiting body surveys to identify the fungal players in these relationships. Fruiting body surveys enable nondestructive sampling, but vastly underestimate fungal presence and diversity and may miss species of critical importance to cavity- nesting birds; thus new methods for such analyses are necessary. Here we present a novel technique to nondestructively sample the wood inside tree cavities, which produces samples that can be processed using DNA-based methods to identify fungi. We tested our method on Red-cockaded Woodpecker Picoides borealis excavations, half of which were from trees with Porodaedalea pini fruiting bodies. Using our new approach, we detected P. pini in 90% of the excavations in trees with fruiting bodies, but also in 60% of the excavations in trees without fruiting bodies and identified nine additional taxa of wood decay fungi that did not have fruiting bodies present. Our approach offers improved detection of fungi through non-destructive sampling of excavated cavities and we developed an improved primer specific to the fungal phylum that contains most wood decay fungi (Basidiomycota), thus providing managers and researchers a critical tool to better determine which fungi are important to cavity-nesting birds.

TI Systematic evaluation of in-house broiler litter windrowing effects on production benefits and environmental impact SO JOURNAL OF APPLIED POULTRY RESEARCH LA English DT Article DE windrowing; Sodium Hydroxide; bacteria; litter; ammonia; temperature ID POULTRY LITTER; BIOSECURITY; FARM; SOIL AB In-house windrowing of broiler litter between flocks has been adopted by producers to reduce pathogens and improve litter quality before chick placement. In this study, 5 consecutive windrow trials were conducted in commercial broiler houses for their effect on litter bacterial populations, organic matter stabilization, cumulative ammonia emissions, and nutrient transformation and compared with litter conditioning (tilling) in adjacent houses. No significant reduction of Clostridium spp. and Escherichia coli populations was found in windrowed litter from d 0 to 7. No significant difference of 7-d mortality was found between windrow and nonwindrow houses. The windrowed house resulted in better foot quality than the nonwindrowed house from 1 of 3 scored flocks. Water-soluble phosphorus increased in both windrowed and nonwindrowed litter; therefore, appreciable biotic and abiotic activity occurred in litter with both treatments after flocks were removed. Overall, no negative effect of windrow treatments on litter quality for agronomic applications was observed. Both the control and windrow treatments resulted in a decrease in litter moisture content (2 to 5%) likely beneficial to bird health conditions. High ammonia emissions persisted after windrow spreading; therefore, a need may exist for an extended period of ventilation or a litter amendment as crucial before chick placement. Litter amendment at a low dose was effective in lowering ammonia concentrations after windrowing and was more economical comparing to operating fans in winter conditions.

TI Polymorphisms in the haemagglutinin gene influenced the viral shedding of pandemic 2009 influenza virus in swine SO JOURNAL OF GENERAL VIROLOGY LA English DT Article ID UNITED-STATES; A VIRUSES; BINDING; RECEPTORS; HUMANS; AIRWAY; PIGS AB Interactions between the viral surface glycoprotein haemagglutinin (HA) and the corresponding receptors on host cells is one important aspect of influenza virus infection. Mutations in HA have been described to affect pathogenicity, antigenicity and the transmission of influenza viruses. Here, we detected polymorphisms present in HA genes of two pandemic 2009 H1N1 (H1N1pdm09) isolates, A/California/04/2009 (Ca/09) and A/Mexico/4108/2009 (Mx/09), that resulted in amino acid changes at positions 186 (S to P) and 194 (L to I) of the mature HA1 protein. Although not reported in the published H1N1pdm09 consensus sequence, the P186 genotype was more readily detected in primary infected and contact-naive pigs when inoculated with a heterogeneous mixed stock of Ca/09. Using reverse genetics, we engineered Ca/09 and Mx/09 genomes by introducing Ca/09 HA with two naturally occurring variants expressing S186/1194 (HA-S/I) and P186/L194 (HA-P/L), respectively. The Ca/09 HA with the combination of P186/L194 with either the Ca/09 or Mx/09 backbone resulted in higher and prolonged viral shedding in naive pigs. This efficiency appeared to be more likely through an advantage in cell surface attachment rather than replication efficiency. Although these mutations occurred within the receptor-binding pocket and the Sb antigenic site, they did not affect serological cross-reactivity. Relative increases of P186 in publicly available sequences from swine H1N1pdm09 viruses supported the experimental data, indicating this amino acid substitution conferred an advantage in swine.

The root-knot and cyst nematodes are of major economic importance to soybean. Consequently, the need for comprehensive understanding of these nematodes directs researchers to combine the transcriptome and proteome analyses to determine the interplay between alterations in soybean gene expression and nematode parasitism. Microarray studies have found several thousand alterations in transcript abundance during nematode parasitism; proteomics has allowed analysis of thousands of root and nematode proteins. The current knowledge of root-nematode interactions is mostly based on transcriptomic data with few proteomic studies. The root-knot and soybean cyst nematode proteins are the topic of this review because they play an important role in manipulation of soybean root cell biology. A better understanding of these proteins and the altered soybean proteins in response to nematode parasitism would help in the discovery of new nematode resistance targets. C1 [Prince, A.

'Jupiter' sweet bell pepper, a tobacco mosaic virus-resistant sweet pepper with a 70-day maturity, was transplanted into single rows on 3-ft centered raised beds with 18 inches between plants (9680 plants/acre) on 28 May 2010 and 27 May 2011, respectively.

Pelargonic acid was applied postdirected each year in mid-June and then reapplied 8 days later. The 15-lb/acre pelargonic acid treatment resulted in the maximum smooth crabgrass control (56%) and broadleaf weed control (66%) at 1 day after the initial spray treatment (DAIT), and 33% yellow nutsedge control at 3 DAIT. Pelargonic acid at 15 lb/acre provided equal or slightly greater smooth crabgrass and broadleaf (cutleaf groundcherry and spiny amaranth) control compared with the 10-lb/acre application, and consistently greater control than the 5-lb/acre rate and the weedy control. Pelargonic acid was less effective at controlling yellow nutsedge than smooth crabgrass and broadleaf weeds. As the rate of pelargonic acid increased from 5 to 15 lb/acre, yellow nutsedge control also increased significantly for all observation dates. Increasing the pelargonic acid application rate increased the crop injury rating. The maximum crop injury occurred for each application rate at 1 DAIT with 7%, 8.0%, and 13.8% injury for pelargonic acid rates 5, 10, and 15 lb/acre, respectively. There was little or no new crop injury after the second postdirected application of pelargonic acid and crop injury following 3 DAIT for application rates was 2% or less. Only the 15-lb/acre pelargonic acid application produced greater fruit per hectare (4784 fruit/ha) and yields (58.65 kg.ha(-1)) than the weedy control (1196 fruit/ha and 19.59 kg.ha(-1)). The weed-free yields (7176 fruit/ha, 178.11 kg.ha(-1), and 24.82 g/fruit) were significantly greater than all pelargonic acid treatments and the weedy control. Pelargonic acid provided unsatisfactory weed control for all rates and did not significantly benefit from the sequential applications. The authors suggest the pelargonic acid be applied to smaller weeds to increase the weed control to acceptable levels (>80%).

TI Pelargonic Acid for Weed Control in Organic Vidalia (R) Sweet Onion Production SO HORTTECHNOLOGY LA English DT Article DE Allium cepa; dry-bulb onion; organic weed control ID CLOVE OIL HERBICIDE; VINEGAR; CORN AB Cultivation using a tine weeder is a proven means to manage weeds in organic Vidalia sweet onion (Allium cepa) production. If the initial cultivation is delayed, emerged weeds are not controlled. In these cases, herbicides derived from natural products could be used to control the emerged weeds before the initial cultivation. Clove oil has been evaluated for this use, but cool-season weed control is inconsistent during the winter season when Vidalia sweet onion are grown. Pelargonic acid is a herbicide that can be derived from natural sources or synthesized. Field trials were conducted from 2011 through 2013 to determine the efficacy of pelargonic acid for cool-season weed control in organic Vidalia sweet onion. All possible combinations of four herbicides and three cultivation regimes using a tine weeder were evaluated. Herbicides evaluated were pelargonic acid (3% and 5% by vol.), clove oil [10% by vol. (2011 and 2012)], D-limonene [14% (2013 only)], and a nontreated control. Cultivation regimes were twice (2x) and four times (4x) at 2-week intervals, and a noncultivated control. Main effects of cultivation and herbicides were independent for all parameters, with no improvement when used in combination. Cultivation 2x and 4x controlled cool-season weeds and improved onion yields, which is consistent with previous research. Pelargonic acid (5%) controlled weeds similar to clove oil (2011 and 2012) and D-limonene (2013), with cool-season weed control efficacy being inconsistent among all herbicides. Onion yield response to weed control from any of the herbicides, including pelargonic acid, also was inconsistent. In organic onion production, inconsistent cool-season performance using pelargonic acid is similar to other herbicides derived from natural sources.

TI Sodium, Saturated Fat, and Trans Fat Content Per 1,000 Kilocalories: Temporal Trends in Fast-Food Restaurants, United States, 2000-2013 SO PREVENTING CHRONIC DISEASE LA English DT Article ID CARDIOVASCULAR-DISEASE; US ADULTS; REDUCTION; PURCHASES; BURDEN AB Introduction Intakes of sodium, saturated fat, and trans fat remain high despite recommendations to limit these nutrients for cardiometabolic risk reduction. A major contributor to intake of these nutrients is foods prepared outside the home, particularly from fast-food restaurants. Methods We analyzed the nutrient content of frequently ordered items from 3 US national fast-food chains: fried potatoes (large French fries), cheeseburgers (2-oz and 4-oz), and a grilled chicken sandwich. We used an archival website to obtain data on sodium, saturated fat, and trans fat content for these items from 2000 through 2013. The amount of each nutrient per 1,000 kcal was calculated to determine whether there were trends in product reformulation. Results Sodium content per 1,000 kcal differed widely among the 3 chains by food item, precluding generalizations across chains. During the 14-year period, sodium content per 1,000 kcal for large French fries remained high for all 3 chains, although the range narrowed from 316-2,000 mg per 1,000 kcal in 2000 to 700-1,420 mg per 1,000 kcal in 2013. Among the items assessed, cheeseburgers were the main contributor of saturated fat, and there was little change in content per 1,000 kcal for this item during the 14-year period. In contrast, there was a sharp decline in saturated and trans fat content of large French fries per 1,000 kcal. Post-2009, the major contributor of trans fat per 1,000 kcal was cheeseburgers; trans fat content of this item remained stable during the 14-year period. Conclusion With the exception of French fries, little evidence was found during the 14-year period of product reformulation by restaurants to become more consistent with dietary guidance to reduce intakes of sodium and saturated fat.

Trends in fast-food restaurant portion sizes can inform policy decisions. We examined the variability of popular food items in 3 fast-food restaurants in the United States by portion size during the past 18 years. Methods Items from 3 national fast-food chains were selected: French fries, cheeseburgers, grilled chicken sandwich, and regular cola. Data on energy, sodium, saturated fat, and trans fat content were collated from 1996 through 2013 using an archival website. Time trends were assessed using simple linear regression models, using energy or a nutrient component as the dependent variable and the year as the independent variable. Results For most items, energy content per serving differed among chain restaurants for all menu items (P <= .04); energy content of 56% of items decreased (beta range, -0.1 to -5.8 kcal) and the content of 44% increased (beta range, 0.6-10.6 kcal). For sodium, the content of 18% of the items significantly decreased (beta range, -4.1 to -24.0 mg) and the content for 33% increased (beta range, 1.9-29.6 mg). Absolute differences were modest. The saturated and trans fat content, post-2009, was modest for French fries. In 2013, the energy content of a large-sized bundled meal (cheeseburger, French fries, and regular cola) represented 65% to 80% of a 2,000-calorie-perday diet, and sodium content represented 63% to 91% of the 2,300-mg-per-day recommendation and 97% to 139% of the 1,500-mg-per-day recommendation. Conclusion Findings suggest that efforts to promote reductions in energy, sodium, saturated fat, and trans fat intakes need to be shifted from emphasizing portion-size labels to additional factors such as total calories, frequency of eating, number of items ordered, menu choices, and energy-containing beverages.

The aim of this study was to evaluate airborne LiDAR (Light Detection And Ranging) to predict aboveground carbon (AGC) stocks in Eucalyptus spp. plantations. Biometric parameters (tree height (Ht) and diameter at breast height (DBH)) were collected from conventional forest inventory sample plots. Regression models predicting total aboveground carbon (AGCt), aboveground carbon in commercial logs (AGCc), and aboveground carbon in harvest residuals (AGCr) from LiDAR-derived canopy structure metrics were developed and evaluated for predictive power and parsimony. The best models from a family of six models were selected based on corrected Akaike Information Criterion (AlCc) and assessed by the root mean square error (RMSE) and coefficient of determination (R-2-adj). The best three models to estimate AGC stocks were AGCt: R-2-adj = 0.81, RMSE = 7.70 Mg.ha(-1); AGCc: R-2-adj = 0.83, RMSE = 5.26 Mg.ha(-1); AGCr: R-2-adj = 0.71, RMSE = 2.67 Mg.ha(-1). This study showed that LiDAR canopy structure metrics can be used to predict AGC stocks in Eucalyptus spp. plantations in Brazil with high accuracy. We conclude that there is good potential to monitor growth and carbon sequestration in Eucalyptus spp. plantations using LiDAR.

The leaf water needs of soybean change over time because of large microenvironment changes over their lifespan, as leaves mature in full sun at the top of the canopy and then become progressively shaded by younger leaves developing above. Leaf hydraulic conductance (K-leaf), a measure of the leaf's water transport capacity, can often be linked to changes in microenvironment and transpiration demand. In this study, we tested the hypothesis that K-leaf would decline in coordination with transpiration demand as soybean leaves matured and aged. Photosynthesis (A), stomatal conductance (g(s)) and leaf water potential (Psi(leaf)) were also measured at various leaf ages with both field- and chamber-grown soybeans to assess transpiration demand. K-leaf was found to decrease as soybean leaves aged from maturity to shading to senescence, and this decrease was strongly correlated with midday A. Decreases in K-leaf were further correlated with decreases in gs, although the relationship was not as strong as that with A. Separate experiments investigating the response of K-leaf to drought demonstrated no acclimation of K-leaf to drought conditions to protect against cavitation or loss of gs during drought and confirmed the effect of leaf age in K-leaf observed in the field. These results suggest that the decline of leaf hydraulic conductance as leaves age keeps hydraulic supply in balance with demand without K-leaf becoming limiting to transpiration water flux.

Considering that the use of new bacterial community analysis techniques (e.g., microbiomics, metagenomics) is becoming more prevalent in the agricultural and environmental sciences and many environmental samples within these disciplines can be physiochemically and microbiologically unique (e.g., fecal and litter/bedding samples from the poultry production spectrum), appropriate and effective DNA extraction methods need to be carefully chosen. Therefore, a novel semi-automated hybrid DNA extraction method was developed specifically for use with environmental poultry production samples. This method is a combination of the two major types of DNA extraction: mechanical and enzymatic. A two-step intense mechanical homogenization step (using bead-beating specifically formulated for environmental samples) was added to the beginning of the "gold standard" enzymatic DNA extraction method for fecal samples to enhance the removal of bacteria and DNA from the sample matrix and improve the recovery of Gram-positive bacterial community members. Once the enzymatic extraction portion of the hybrid method was initiated, the remaining purification process was automated using a robotic workstation to increase sample throughput and decrease sample processing error. In comparison to the strict mechanical and enzymatic DNA extraction methods, this novel hybrid method provided the best overall combined performance when considering quantitative (using 16S rRNA qPCR) and qualitative (using microbiomics) estimates of the total bacterial communities when processing poultry feces and litter samples.

We have recently identified a bitter sensing neuron in the labellum of female Aedes aegypti that responds to DEET and other repellents, as well as bitter quinine, through direct electrophysiological investigation. These gustatory receptor neuron responses prompted our sequencing of total mRNA from both male and female labella and tarsi samples to elucidate the putative chemoreception genes expressed in these contact chemoreception tissues. Samples of tarsi were divided into pro-, meso-and metathoracic subtypes for both sexes. We then validated our dataset by conducting qRT-PCR on the same tissue samples and used statistical methods to compare results between the two methods. Studies addressing molecular function may now target specific genes to determine those involved in repellent perception by mosquitoes. These receptor pathways may be used to screen novel repellents towards disruption of host-seeking behavior to curb the spread of harmful viruses.

TI Differences in relative iron bioavailability in traditional Bangladeshi meal plans SO FOOD AND NUTRITION BULLETIN LA English DT Article DE Bangladesh; bioavailability; Caco-2 cell culture; dal; iron; lentils; meal plan models; phytic acid; rice ID CELL-CULTURE MODEL; CACO-2 CELLS; YOUNG-WOMEN; PROTEIN DIGESTIBILITY; LENS-CULINARIS; COMMON BEANS; FOOD; COOKING; ABSORPTION; LENTILS AB Background. Iron deficiency is the most common nutrient deficiency worldwide. Large intakes of micronutrient-poor staple crops, coupled with low intakes of highly bioavailable dietary iron, are a major cause of this deficiency. Objective. To examine the concentration and relative bioavailability of iron in several models (n=23) of traditional Bangladeshi meals (rice, lentils/dal, vegetable, and fish), as well as the effect of removal of the lentil seed coat on the nutritional quality of iron. Methods. The relative bioavailability of iron was assessed by the in vitro/Caco-2 cell culture method, iron concentration by an inductively coupled argon-plasma emission spectrometer (ICAP-ES), and phytic acid concentration by colorimetric assay. The recipes contained 75% to 85% rice, 0% to 15% dal (containing whole or dehulled lentils), 0% to 15% vegetable curry, and 0% to 8% fish. Results. While the iron concentrations of recipes containing dehulled dal were significantly lower than those of recipes containing whole dal (p=.005), seed coat removal doubled relative iron bioavailability and increased phytic acid concentration (p<.001). The addition of fish to the meals had no significant effect on relative iron bioavailability. Iron concentration and relative iron bioavailability were correlated in the recipes containing dehulled dal (r=0.48, p=.03), but not whole dal (r=0.047, p=.84). Conclusions. The total amount of iron absorbed from traditional Bangladeshi meals is dependent upon iron concentration, and dehulling lentils removes inhibitory factors increasing iron uptake but also increases the density of phytic acid in the lentil sample. Thus, along with breeding for high iron concentration and bioavailability (i.e., biofortification), seed coat removal plus measures to lower phytic acid concentrations may be an important strategy to improve the bioavailability of iron in lentils and other pulse crops.

TI Employment of the "Role 2-Plus": Lessons Learned in a Time of High OPTEMPO SO MILITARY MEDICINE LA English DT Editorial Material AB From 2009 to 2014, the medical units at Fort Bragg, North Carolina, gained extensive experience in the nondoctrinal employment of the Forward Surgical Team (FST) combined with an Area Support Medical Company (ASMC) or Brigade Support Medical Company (BSMC). The setup and execution of the so-called "Role 2-plus" offers multiple operational and clinical advantages over solitary employment, but also presents some significant logistical challenges without proper planning. At the time of authorship, current literature describes this entity, (1) but information or guidance as to the actual employment of the Role 2-plus (including web-based outlets such as Center for Army Lessons Learned) is almost nonexistent. (1-6) Former commanders of these units would like to share and document some of the lessons learned during a time of exceptionally high operational tempo (OPTEMPO).

A field experiment was conducted during 2002 to 2007 on a Vanmeter farm of the Ohio State University South Centers at Piketon Ohio, USA to assess the long term influence of tillage practices and crop rotation on soil particulate organic matter allied with carbon and nitrogen. Tillage treatments including conventional (CT) and No-till (NT) were factored into continuous corn (CC), corn-soybean (CS) and corn-soybean-wheat-cowpea (CSW) rotations by following randomized complete block design with 6 replications. The results of long-term study showed that 12 percent of significant increase was observed in the particulate organic matter (POM) in NT by the passage of time. The particulate organic carbon (POC) concentration under NT increased (15 %) significantly when CT converted in to NT over five year. Furthermore, particulate organic nitrogen (PON) increased (12%) significantly under NT than under CT. Crop rotation had significant effects on POM and the effects were more prominent in the CSW rotation. The POM, POC concentration increased with time in CC (11%) and CSW (15%) rotations. As soil depth increases, significant decrease was observed in POM, POC and PON concentrations regardless of tillage and crop rotation treatments. Tillage and crop rotation had no significant influence on the physical parameters; however, with time as a factor in the interaction significantly influenced the physical properties. Changes in the physical properties of the soil by tillage practices and crop rotation are mainly due to soil disturbance, placement, amount and type of added biomass crop in the soil ecosystem. Physical properties of soil facilitate microbial activities, support chemical functions, improve protection C and improve the quality of soil.

TI Scaling and Pedotransfer in Numerical Simulations of Flow and Transport in Soils SO VADOSE ZONE JOURNAL LA English DT Article ID SATURATED HYDRAULIC CONDUCTIVITY; HETEROGENEOUS MEDIA; WATER-RETENTION; BULK-DENSITY; DEPENDENCY; AQUIFERS; INFILTROMETER; PATHWAYS; MOISTURE; TEXTURE AB Flow and transport parameters of soils in numerical simulations need to be defined at the support scale of computational grid cells. Such support scale can substantially differ from the support scale in laboratory or field measurements of flow and transport parameters. The scale dependence of flow and transport parameters essentially precludes the direct use of measured or pedotransfer-estimated parameter values in numerical simulations. The hypothesis of this work was that a support-based scaling law can be introduced that can convert pedotransfer-estimated saturated hydraulic conductivity values into values to be used over grid cells for finite-element-based simulations of water flow and tracer transport in variably saturated soils. A 4-month-long experiment was conducted at the USDA-ARS experimental site where Cl- as a tracer was applied with a pulse of irrigation water and its transport in groundwater and variably saturated shallow coarse-textured soils was monitored in two rows of wells on a daily basis. The HYDRUS-3D software was used to set and calibrate the Richards model for flow simulations and the convective-dispersive equation for transport simulations. Saturated hydraulic conductivity values were estimated with class pedotransfer functions derived from the USDA database containing results of about 1000 measurements in soils of different textures and bulk densities. A power law scaling for the saturated hydraulic conductivity was suggested based on literature data. When only two parameters of the scaling law rather than nine values of hydraulic conductivity from nine soil materials were calibrated, using the scaled saturated hydraulic conductivity values resulted in an accuracy of simulations that was similar to the accuracy of the calibrated model results. Upscaling of pedotransfer-estimated saturated hydraulic conductivities can provide reasonable estimates for numerical flow and transport modeling in variably saturated soils.

In this study, we investigated whether soil hydraulic properties are related to soil water content variability at the field scale. We used the mean relative difference ( MRD) of soil water content and saturation degree to describe the spatial soil water content variability of a 2- yr time series of soil water content measured with a sensor network at 41 locations in the Rollesbroich catchment ( Germany). Hydraulic properties were described by the van Genuchten- Mualem ( VGM) model and were estimated by inverse modeling of soil water content data using the Hydrus- 1D model for each location. The feasible parameter space for the inverse modeling was derived using the Rosetta pedotransfer functions from information on sand, silt, and clay contents and bulk density from 273 soil samples taken in the catchment. Our inverse modeling results were able to reproduce the observed time series of soil water content with a root mean square error < 0.08 cm3 cm- 3 and R2 > 0.75. We found that the MRDs of soil water content were positively correlated with the saturated water content ( qs) and shape- fitting n parameters and negatively correlated with the shape- fitting a and saturated hydraulic conductivity ( Ks) parameters of the VGM model. Moreover, the MRDs of the saturation degree were strongly correlated with the a and n parameters that determine the shape of the VGM model. C1 [Qu, W.; Bogena, H. R.; Huisman, J.

Indigenous cultivated (landrace) potatoes and wild potato species, all classified as Solanum section Petota, are widely used for potato improvement. Members of section Petota are broadly distributed in the Americas from the southwestern United States to the Southern Cone of South America. The latest comprehensive taxonomic treatment of section Petota was published by John (Jack) Hawkes in 1990; it recognized seven cultivated species and 228 wild species, divided into 21 taxonomic series. Since 1990, intensive field collections from throughout the range of the group, coupled with morphological and molecular studies, have halved the number of species and elucidated new ingroup and outgroup relationships. The recent sequencing of the potato genome has greatly accelerated investigation of all aspects of potato biology and allows us to address new questions not conceivable before. The purpose of this review is to provide a historical overview and update since 1990 of the systematics, diversity, genetics, domestication, evolution, and breeding of Solanum section Petota that will serve as a reference for the next generation of studies in the potato.

TI Brucella papionis sp nova, isolated from baboons (Papio spp.) SO INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY LA English DT Article ID MOLECULAR CHARACTERIZATION; GENUS BRUCELLA; INSERTION-SEQUENCE; VACCINE STRAINS; MARINE MAMMALS; IDENTIFICATION; PINNIPEDIALIS; OVIS; PCR; DIFFERENTIATION AB Two Gram-negative, non-motile, non-spore-forming coccoid bacteria (strains F8/08-60(T). and F8/08-61) isolated from clinical specimens obtained from baboons (Papio spp.) that had delivered stillborn offspring were subjected to a polyphasic taxonomic study. On the basis of 16S rRNA gene sequence similarities, both strains, which possessed identical sequences, were assigned to the genus Brucella. This placement was confirmed by extended multilocus sequence analysis (MLSA), where both strains possessed identical sequences, and whole-genome sequencing of a representative isolate. All of the above analyses suggested that the two strains represent a novel lineage within the genus Brucella. The strains also possessed a unique profile when subjected to the phenotyping approach classically used to separate species of the genus Brucella, reacting only with Brucella A monospecific antiserum, being sensitive to the dyes thionin and fuchsin, being lysed by bacteriophage Wb, Bk2 and Fi phage at routine test dilution (RTD) but only partially sensitive to bacteriophage Tb, and with no requirement for CO2 and no production of H2S but strong urease activity. Biochemical profiling revealed a pattern of enzyme activity and metabolic capabilities distinct from existing species of the genus Brucella. Molecular analysis of the omp2 locus genes showed that both strains had a novel combination of two highly similar omp2b gene copies. The two strains shared a unique fingerprint profile of the multiple-copy Brucella-specific element IS711. Like MLSA, a multilocus variable number of tandem repeat analysis (MLVA) showed that the isolates clustered together very closely, but represent a distinct group within the genus Brucella. Isolates F8/08-60(T) and F8/08-6(T) could be distinguished clearly from all known species of the genus Brucella and their biovars by both phenotypic and molecular properties. Therefore, by applying the species concept for the genus Brucella suggested by the ICSP Subcommittee on the Taxonomy of Brucella, they represent a novel species within the genus Brucella, for which the name Bruaella papionis sp. nov. is proposed, with the type strain F8/0860(T) (=NCTC 13660(T)=CIRMBP 0958(T)).

Several genes induced by drought stress include functional genes and regulatory transcription factors. The Arabidopsis thaliana DREB1D transcription factor driven by the constitutive and ABA-inducible promoters was introduced into soybean through Agrobacterium tumefaciens-mediated gene transfer. Several transgenic lines were generated and molecular analysis was performed to confirm transgene integration. Transgenic plants with an ABA-inducible promoter showed a 1.5- to two-fold increase of transgene expression under severe stress conditions. Under wellwatered conditions, transgenic plants with constitutive and ABA-inducible promoters showed reduced total leaf area and shoot biomass compared to non-transgenic plants. No significant differences in root length or root biomass were observed between transgenic and non-transgenic plants under non-stress conditions. When subjected to gradual water deficit, transgenic plants maintained higher relative water content because the transgenic lines used water more slowly as a result of reduced total leaf area. This caused them to wilt slower than non-transgenic plants. Transgenic plants showed differential drought tolerance responses with a significantly higher survival rate compared to nontransgenic plants when subjected to comparable severe water-deficit conditions. Moreover, the transgenic plants also showed improved drought tolerance by maintaining 17-24 % greater leaf cell membrane stability compared to non-transgenic plants. The results demonstrate the feasibility of engineering soybean for enhanced drought tolerance by expressing stress-responsive genes.

Effects on watermelon are devastating, with total vine collapse, often near harvest, and fruit rendered unmarketable by brown, discolored flesh. The epidemiology of SqVYV was studied in a I-ha field of 'Fiesta' watermelon over six growing seasons (1 to VI) to characterize the spatial patterning of disease and temporal rate of disease progress, as well as its association with Cucurbit leaf crumple virus (CuLCrV) and Cucurbit yellow stunting disorder virus (CYSDV), two additional whitefly-transmitted viruses that often occur with SqVYV. The field was scouted at regular intervals for the length of the season for incidence of virus and number of whiteflies. Incidence of SqVYV reached 100% during seasons I, II, and V and 20% during season III. SqVYV did not occur during seasons IV and VI. SqVYV progressed in a characteristic logistic fashion in seasons I, II, and V but less so in season Ill. The rate of disease progress was similar for the three seasons with high disease incidence, with an average value of 0.18. A positive correlation between the area under the disease progress curve and whitefly-days was found, where both progress curves were calculated as a function of thermal time (degree days, base 0 degrees C). SqVYV displayed significant but variable levels of aggregation, as indicated by its fit to the beta-binomial distribution, the binary power law, and ordinary runs analysis. Association analysis indicated that the viruses were largely transmitted independently. Results of this study provide epidemiological information that will be useful in the development of management strategies for SqVYV-induced vine decline, and provide new information for CuLCrV and CYSDV.

TI Pathogenicity, Fungicide Resistance, and Genetic Variability of Phytophthora rubi Isolates from Raspberry (Rubus idaeus) in the Western United States SO PLANT DISEASE LA English DT Article ID ROOT-ROT; RED RASPBERRY; POPULATIONS; IDENTITIES; INFESTANS; METALAXYL; FIELD AB Root rot of raspberry (Rubus idaeus), thought to be primarily caused by Phytophthora rubi, is an economically important disease in the western United States. The objectives of this study were to determine which Phytophthora species are involved in root rot, examine the efficacy of different isolation methods (cane, root, and root/soil baiting with young raspberry plants), and determine if pathogenicity, fungicide resistance, and/or genetic variation exists among P rubi isolates collected from raspberry fields in Washington, Oregon, and California. Of 275 samples, direct isolation from cane material resulted in a greater number of P rubi isolates (39%), whereas root/soil baiting yielded the least (11%). Sequencing of the internal transcribed spacer region of 210 of the total 597 collected Phytophthora isolates showed that all but one isolate (identified as P. bisheria) were P rubi. Results of the pathogenicity and fungicide resistance to mefenoxam comparing 14 total isolates from Washington, Oregon, and California showed that isolates were similarly virulent against red raspberry and the EC50 frequency distributions showed no significant difference. These results, combined with amplified fragment length polymorphism results show that P rubi isolates from Washington, Oregon, and California represent one large mixed population. This work provides novel insights into the isolation and biology of P rubi in western U.S. raspberry production systems.

TI Lineage, Temperature, and Host Species have Interacting Effects on Lesion Development in Phytophthora ramorum SO PLANT DISEASE LA English DT Article ID SUDDEN OAK DEATH; 3 CLONAL LINEAGES; NORTH-AMERICAN; UNITED-STATES; US NURSERIES; IN-VITRO; MICROSATELLITE MARKERS; PLANT PATHOGEN; FOREST DISEASE; MATING-TYPE AB There are four recognized clonal lineages of the pathogen Phytophthora ramorum. The two major lineages present in North America are NA1 and NA2. With a few exceptions, NA1 is found in natural forest ecosystems and nurseries, and NA2 is generally restricted to nurseries. Isolates from the NA1 and NA2 lineages were used to infect rhododendron, camellia, and California bay laurel in detached leaf assays to study the effects of lineage, temperature, and host on pathogenicity and host susceptibility. Isolates within both lineages were highly variable in their ability to form lesions on each host. There was also a tendency toward reduced lesion size in successive trials, suggesting degeneration of isolates over time. Temperature had a significant effect on lesion size, with a response that varied depending on the host and isolate. Phenotypic differences between lineages appear to be heavily influenced by the representation of isolates used, host, and temperature. The importance of temperature, host, and lineage are discussed with respect to disease management, as well as future range expansions and migrations of the pathogen. C1 [Eyre, C. A.; Hayden, K.

TI Woody Regeneration in a Southern Appalachian Quercus Stand Following Wind Disturbance and Salvage Logging SO CASTANEA LA English DT Article DE Acer rubrum; compounded disturbance; Quercus; regeneration; salvage logging ID EASTERN UNITED-STATES; CANOPY ACCESSION STRATEGIES; OAK FORESTS; RED MAPLE; ACCELERATED SUCCESSION; CUMBERLAND PLATEAU; PRESCRIBED FIRE; NORTH-AMERICA; GROWTH; PATTERNS AB In the eastern United States, the practice of salvage logging is common to reclaim economic losses and/or reduce fuel loading following a natural disturbance. A current hypothesis states that two disturbances in rapid succession (i.e., compounded disturbance) have a cumulative severity of impact and may displace the successional trajectory further than either disturbance occurring separately. On 20 April 2011, Bankhead National Forest in Alabama was affected by an EF1 tornado with accompanying straight-line winds. Much of the damage was salvaged, however adjacent disturbance in a Wilderness Area was not harvested. A unique set of conditions allowed for comparisons of woody regeneration within a single stand, reducing uncontrolled variables to test the compounded disturbance hypothesis at a fine spatial scale. After two growing seasons, species richness, species evenness, and Shannon diversity of seedlings and saplings did not significantly differ by disturbance class. We found seedling density significantly differed between functional groups and we noted a significant interaction between functional groups and disturbance classes. In the sapling layer, density was significantly different among functional groups and among disturbance classes, but our results did not reveal a significant interaction between these factors. The wind disturbance accelerated succession in the Quercus stand toward dominance by shade-tolerant species, notably A. rubrum, and the salvage operation amplified the Quercus-to-Acer transition. However, even in wind-disturbed areas that were not salvaged, the regeneration model predicted A. rubrum to have more than twice the density of all combined Quercus species in the future stand.

TI Quantifying understorey vegetation in the US Lake States: a proposed framework to inform regional forest carbon stocks SO FORESTRY LA English DT Article ID UNITED-STATES; NORTHERN MINNESOTA; SOUTHEAST ALASKA; BIOMASS; ECOSYSTEMS; COVER; MODELS; REGRESSION; STAND; PINE AB The contribution of understorey vegetation (UVEG) to forest ecosystem biomass and carbon (C) across diverse forest types has, to date, eluded quantification at regional and national scales. Efforts to quantify UVEG C have been limited to field-intensive studies or broad-scale modelling approaches lacking field measurements. Although large-scale inventories of UVEG C are not common, species-and community-level inventories of vegetation structure are available and may prove useful in quantifying UVEG C stocks. This analysis developed a general framework for estimating UVEG C stocks by employing per cent cover estimates of UVEG from a region-wide forest inventory coupled with an estimate of maximum UVEG C across the US Lake States (i.e. Michigan, Minnesota and Wisconsin). Estimates of UVEG C stocks from this approach reasonably align with expected C stocks in the study region, ranging from 0.86 +/- 0.06 Mg ha(-1) in red pine-dominated to 1.59 +/- 0.06 Mg ha(-1) for aspen/birch-dominated forest types. Although the data employed here were originally collected to assess broad-scale forest structure and diversity, this study proposes a framework for using UVEG inventories as a foundation for estimating C stocks in an often overlooked, yet important ecosystem C pool.

Results included significant suppression of weeds and soilborne pathogens equal to commercial chemigation of chloropicrin with 1,3-dichloropropene (Pic-Clor 60). Also, the combination of steam treatment with soil amendments of mustard seed meal (MSM; two of four trials included treatment), a fertilizer and source of additional organic matter, showed very favorable strawberry production in terms of yield as Well as weed and pathogen control. Soil nitrogen-containing ions were monitored at two of the sites and the MSM treatment significantly elevated available soil nitrates by the time of transplanting as did the steam treatment alone, but only significantly at one of the sites.

In general, N-2 and N2O in excess of atmospheric equilibrium were found in groundwater virtually everywhere that was sampled. Excess N-2 in groundwater ranged from undetectable to 616 mu mol N-2-N/l, the latter representing c. 50% of background N-2. The N2O-N concentrations varied from undetectable to 75 mu M, and usually greatly exceeded values at atmospheric equilibrium (25-30 nM); however, N2O was generally 1-10% of excess N-2. Intermediate levels of deficit and excess N-2 in flowing streams (-65 to +250 mu mol N-2-N/L) resulting from both abiotic and biotic processes were also measured. In vadose zone gases, multiple N-2/Ar gas profiles were measured which exhibited seasonal variations with below atmospheric values when the soil was warming in spring/summer and above atmospheric values when groundwater was cooling in fall/winter. Both abiotic and biotic processes contributed to the excess N-2 and N2O that was observed. The current data indicate that large concentrations of excess N gases can accumulate within soil, groundwater, and streams of agriculturally dominated watersheds. When excess N gases are exchanged with the atmosphere, the net fluxes to the atmosphere may represent an important loss term for watershed N budgets. C1 [Fox, R. J.; Fisher, T. R.; Gustafson, A.

The vertical and horizontal spatial distribution of plant-parasitic nematodes was determined in two Washington V. vinifera vineyards. Others variables measured in these vineyards included soil moisture content, fine root biomass, and root colonization by arbuscular mycorhizal fungi (AMF). Meloidogyne hapla and M. xenoplax were aggregated under irrigation emitters within the vine row and decreased with soil depth. Conversely, Pratylenchus spp. populations were primarily concentrated in vineyard alleyways and decreased with depth. Paratylenchus sp. and X. americanum were randomly distributed within the vineyards. Soil water content played a dominant role in the distribution of fine roots and plant-parasitic nematodes. Colonization of fine roots by AMF decreased directly under irrigation emitters; in addition, galled roots had lower levels of AMF colonization compared with healthy roots. These findings will help facilitate sampling and management decisions for plant-parasitic nematodes in Washington semi-arid vineyards.

The identity of the nematode's symbiotic bacteria was elucidated and found to be Photorhabdus luminescens subsp. luminescens. Beneficial traits pertinent to biocontrol (environmental tolerance and virulence) were characterized. The range of temperature tolerance in the H. floridensis strains was broad and showed a high level of heat tolerance. The H. floridensis strains caused higher mortality or infection in G. mellonella at 30 degrees C and 35 degrees C compared with S. riobrave (355), a strain widely known to be heat tolerant, and the H. floridensis strains were also capable of infecting at 17 degrees C whereas S. riobrave (355) was not. However, at higher temperatures (37 degrees C and 39 degrees C), though H. floridensis readily infected G. mellonella, S. riobrave strains caused higher levels of mortality. Desiccation tolerance in H. floridensis was similar to Heterorhabditis indica (Hom1) and S. riobrave (355) and superior to S. feltiae (SN). H. bacteriophora (Oswego) and S. carpocapsae (All) exhibited higher desiccation tolerance than the H. floridensis strains. The virulence of H. floridensis to four insect pests (Aethina tumida, Conotrachelus nenuphar, Diaprepes abbreviatus, and Tenebrio molitor) was determined relative to seven other nematodes: H. bacteriophora (Oswego), H. indica (Hom1), S. carpocapsae (All), S. feltiae (SN), S. glaseri (4-8 and Vs strains), and S. riobrave (355). Virulence to A. tumida was similar among the H. floridensis strains and other nematodes except S. glaseri (Vs), S. feltiae, and S. riobrave failed to cause higher mortality than the control. Only H. bacteriophora, H. indica, S. feltiae, S. riobrave, and S. glaseri (4-8) caused higher mortality than the control in C. nenuphar. All nematodes were pathogenic to D. abbreviatus though S. glaseri (4-8) and S. riobrave (355) were the most virulent. S. carpocapsae was the most virulent to T. molitor. In summary, the H. floridensis strains possess a wide niche breadth in temperature tolerance and have virulence and desiccation levels that are similar to a number of other entomopathogenic nematodes. The strains may be useful for biocontrol purposes in environments where temperature extremes occur within short durations.

Cultivars FiberMax 960 BR (susceptible to M. incognita) and Stoneville 5599 BR (moderately resistant) were tested together in three trials, and PD94042 (germplasm, susceptible) and 120R1B1 (breeding line genetically similar to PD94042, but highly resistant) were paired in two additional trials. Inoculation with M. incognita generally resulted in increases in root gall ratings and egg counts per gram of root compared with the noninoculated control, as well as reductions in plant dry weight, root weight, leaf area, boll number, and boll dry weight, thereby confirming that growth of our greenhouse-grown plants was reduced in the same ways that would be expected in field-grown plants. In all trials, M. incognita caused reductions in height-to-node ratios. Nematode infection consistently reduced the area under the height-to-node ratio curves for all genotypes, and these reductions were similar for resistant and susceptible genotypes (no significant genotype 3 inoculation interaction). Our study is the first to show that infection by M. incognita is associated with reduced chlorophyll content in cotton leaves, and the reduction in the resistant genotypes was similar to that in the susceptible genotypes (no interaction). The susceptible PD94042 tended to have increased leaf temperature compared with the genetically similar but highly resistant 120R1B1 (P < 0.08), likely attributable to increased water stress associated with M. incognita infection.

Whether dietary fatty acids modify LPL associated obesity risk is unknown. Methods and results: We examined five single nucleotide polymorphisms (SNPs) (rs320, rs2083637, rs17411031, rs13702, rs2197089) for potential interaction with dietary fatty acids for obesity traits in 1171 participants (333 men and 838 women, aged 45-75 y) of the Boston Puerto Rican Health Study (BPRHS). In women, SNP rs320 interacted with dietary polyunsaturated fatty acids (PUFA) for body mass index (BMI) (P = 0.002) and waist circumference (WC) (P = 0.001) respectively. Higher intake of PUFA was associated with lower BMI and WC in homozygotes of the major allele (TT) (P = 0.01 and 0.005) but not in minor allele carriers (TG and GG). These interactions were replicated in an independent population, African American women of the Atherosclerosis Risk in Communities (ARIC) study (n = 1334). Conclusion: Dietary PUFA modulated the association of LPL rs320 with obesity traits in two independent populations. These interactions may be relevant to the dietary management of obesity, particularly in women. (C) 2014 Published by Elsevier B.V. C1 [Ma, Y.; Smith, C. E.; Lee, Y. C.; Richardson, K.; Parnell, L.

The maize (Zea mays) leaf is an ideal system to study plant morphogenesis as it is subdivided into a proximal sheath and a distal blade, each with distinct developmental patterning. Specialized ligule and auricle structures form at the blade-sheath boundary. The auricles act as a hinge, allowing the leaf blade to project at an angle from the stem, while the ligule comprises an epidermally derived fringe. Recessive liguleless1 mutants lack ligules and auricles and have upright leaves. We used laser microdissection and RNA sequencing to identify genes that are differentially expressed in discrete cell/tissue-specific domains along the proximal-distal axis of wild-type leaf primordia undergoing ligule initiation and compared transcript accumulation in wild-type and liguleless1-R mutant leaf primordia. We identified transcripts that are specifically upregulated at the blade-sheath boundary. A surprising number of these "ligule genes" have also been shown to function during leaf initiation or lateral branching and intersect multiple hormonal signaling pathways. We propose that genetic modules utilized in leaf and/or branch initiation are redeployed to regulate ligule outgrowth from leaf primordia.

Vaccination for low pathogenicity AIV is also becoming routine in regions where there is a high level of field challenge. In contrast, some countries will not use vaccination at all and some will only use it on an emergency basis during eradication efforts (i.e. stamping-out). There are pros and cons to each approach and, since every outbreak situation is different, no one method will work equally well in all situations. Numerous practical aspects must be considered when developing an AIV control program with vaccination as a component, such as: (1) the goals of vaccination must be defined; (2) the population to be vaccinated must be clearly identified; (3) there must be a plan to obtain and administer good quality vaccine in a timely manner and to achieve adequate coverage with the available resources; (4) risk factors for vaccine failure should be mitigated as much as possible; and, most importantly, (5) biosecurity must be maintained as much as possible, if not enhanced, during the vaccination period.

We previously reported that ablation of the ghrelin receptor, growth hormone secretagogue receptor (GHS-R), attenuates age-associated obesity and insulin resistance. Ghrelin and obestatin are derived from the same preproghrelin gene. Here we showed that in brown adipocytes, ghrelin decreases the expression of thermogenic regulator but obestatin increases it, thus showing the opposite effects. We also found that during aging, plasma ghrelin and GHS-R expression in brown adipose tissue (BAT) are increased, but plasma obestatin is unchanged. Increased plasma ghrelin and unchanged obestatin during aging may lead to an imbalance of thermogenic regulation, which may in turn exacerbate thermogenic impairment in aging. Moreover, we found that GHS-R ablation activates thermogenic signaling, enhances insulin activation, increases mitochondrial biogenesis, and improves mitochondrial dynamics of BAT. In addition, we detected increased norepinephrine in the circulation, and observed that GHS-R knockdown in brown adipocytes directly stimulates thermogenic activity, suggesting that GHS-R regulates thermogenesis via both central and peripheral mechanisms. Collectively, our studies demonstrate that ghrelin signaling is an important thermogenic regulator in aging. Antagonists of GHS-R may serve as unique anti-obesity agents, combating obesity by activating thermogenesis. C1 [Lin, Ligen; Lee, Jong Han; Bongmba, Odelia Y.

Tree cover in particular is often used as a determinant of carbon storage for local and national level urban forest assessments. However, the relationships among variables describing the biophysical and socioeconomic environment and carbon are not simple statistical ones. Instead, there are complex interactions that can have either a unidirectional causal effects, or produce indirect effects through interactions with other ecosystem structure and landscape characteristics. Thus, understanding the direct and indirect effects of structure, composition, and landscape characteristics is key to quantifying ecosystem services. This study used field data from plots across an urban watershed, site-specific biomass equations, and structural equation modeling of urban forest structure and landscape variables to quantify the causal influences of tree cover, land use, stand density, species composition and diversity on carbon stores. Our path analysis shows that the effect of tree cover on carbon stores is not only direct but also indirect and influential through basal area and composition. Findings suggest that species composition, species diversity and land use have much more complex relationships than previously reported in the urban forest literature. The use of path analysis in these types of studies also presents a novel method to better analyze and quantify these direct and indirect effects on urban forest carbon stores. Findings have implications for urban forest ecosystem assessments that use tree cover as the sole metric for inferring ecosystem functions and services. (C) 2014 Elsevier B.V. All rights reserved.

The case of lean finely textured beef in the United States SO FOOD POLICY LA English DT Article DE LFTB; Meat demand; Switching regime; Media effect; Food scares; Consumer concerns ID US MEAT DEMAND; STRUCTURAL-CHANGE; INFORMATION; IMPACT; FOOD; SYSTEM; PROMOTION; PRODUCTS; INDUSTRY; QUALITY AB In 2012, the media paid extra attention to lean finely textured beef (LFTB), an inexpensive lean beef product extracted from low-valued fatty trim. The media's negative portrayal of LFTB as an unnecessary and unsavory additive to ground beef products corresponded with a spike in reports over a 6-month period. Since LFTB is often used in ground beef, it is likely that consumption of LFTB-based ground beef products and other meats could be affected. This paper used weekly meat production and sales data to assess how media depictions of LFTB affect consumer demand. We used a Central Bureau of Statistics model to test whether media portrayal affects the consumption of aggregate meats and beef cuts: pork, chicken, turkey, Choice beef, Prime beef, Select beef and ground beef. Results indicate that media portrayal of LFTB, measured by the number of articles on the subject weighted by consumer readership, did not lead to significant changes in consumer demand across meats or within the beef category immediately. However, consumer purchases of pork, turkey and Prime beef were affected two weeks or greater after news reports of LFTB surfaced. Nevertheless, those effects were temporary and waned or disappeared during later weeks. Our look at the LFTB controversy informs food policy by studying the media sources from which consumers obtain their information. As the temporary effects of news media on consumer demand for aggregate meats and disaggregate beef cuts suggest, consumers may benefit from receiving their news from industry and government sources instead.

Iron deficiency is common in humans, making iron supplementation of foods an important area of research. Edible sprouts are a rich source of minerals and phenolic compounds beneficial to human health; our objective was therefore to investigate the effects of iron supplementation in sprouts. We supplemented iron concentrations in three species of edible sprouts (alfalfa, broccoli, and radish) by soaking the seeds in a high-iron solution, and subsequently measured the concentration of minerals and of phenolic compounds. Seeds were soaked in either Fe(III)-EDTA or Fe(III)-citrate at concentrations of 2.5, 5.0, or 10 mM for 5-8 h, and then were maintained with distilled water in a commercial sprouter for 5 days. The soaking treatment significantly increased the iron concentration in 5-day-old alfalfa sprouts by up to 1.8 times the concentration observed in the controls. For broccoli and radish sprouts, an insignificant trend toward higher Fe concentrations was observed. The accumulated iron in treated alfalfa sprouts was negatively associated with concentrations of other minerals such as Ca, Mg, Mn, and Na. Treated alfalfa sprouts showed a significant increase of 8.0-36.4% in total phenolic concentrations compared to the controls, whereas broccoli and radish sprouts showed no significant change in phenolic concentrations. In summary, soaking seeds with iron chelates enhanced the iron concentration of sprouts, especially alfalfa sprouts, and had a positive or neutral impact on the concentration of phenolic compounds, suggesting that this treatment could be used to improve the nutritional quality of some types of edible sprouts.

The treated juice was packaged in PET bottles or PET bottles coated with potassium sorbate and sodium benzoate, and stored at 4 degrees C for 84 days. Samples were assessed every 7 days for total aerobic bacteria and yeast and mold. Untreated juice had less than one week of shelf-life, while untreated juices in antimicrobial bottles had 56 days. Juices treated with PEF alone had a shelf-life of 21 days (bench scale) and over 84 days (pilot scale). juices treated with PEF and stored in antimicrobial bottles had a shelf-life over 84 days for both scale tests, which significantly extended the microbiological shelf-life of pomegranate juice. Industrial relevance: Pulsed electric field (PEF), one of novel non-thermal processing technologies, has been studied intensively worldwide for the last decades. However, most of them were done at laboratory scale and few were at pilot or commercial scale. In addition, PEF processing alone may not provide enough shelf-life of juice as juice industry expects. The work in this paper shows the side-by-side comparison of PEF processing at lab and pilot scales and demonstrates that the combination of PEF with antimicrobial battle packaging significantly extended the shelf-life of juice. The use of a large scale PEF processing system and the combination of antimicrobial packaging provide juice manufacturers an innovate approach for enhancing the safety and extending the shelf-life of juice products.

A long term experiment was conducted on Vanmeter farm of the Ohio State University South Centers at Piketon Ohio, USA from 2002 to 2007. Crop rotation treatments included were continuous corn (CC), corn-soybean (CS) and corn-soybean-wheat-cowpea (CSW) rotations. Randomized complete block design with 6 replications was used under natural field conditions. The findings of this long-term study revealed that multiple cropping had significantly improved humified carbon fractions compared to mono-cropping system. Although total humified carbon (THOC), sugar free humified carbon (HOC) concentration were non-significant however, humin (NH) contents, humic (HA), fulvic acids (FA), humic and fulvic acid associated glucose (HA-NH and FA-NH) were significantly affected by various crop rotations within five years. The soil under CC had 22-52% significantly greater NH concentration than CSW and CS rotations respectively. Similarly all crop rotations had shown 5-16 increase in HA and 5-17% decreased in FA over time. Likewise soil under CC had 16 and 54% greater HA-NH concentration as compared to CSW and CS rotations. The FA-NH concentration increased significantly by 27-51% in soil under all treatments over time. The soil under CSW had greater HA/FA (1.6) fallowed by CC (1.4) and CS (1.1). Soils under CSW had significantly greater HA/HOC (12-18%) as compare to CC and CS respectively. Conversely, the value of FA/HOC decreased (1-23%) in soil under all crop rotation treatments within five years. Degree of humification (DH) had shown a significant increase (7-12%) in soil under all treatments as compared to 2002. Irrespective of crop rotation THOC, HOC, NH, humin, HA, HR and FA/HOC concentration decreased significantly with increase in soil depth. While fulvic acid concentration HA/HOC in all crop rotation increased with increase in soil depth. The effect of crop rotation on humified C fractions could be because of variations in type, amount and quality of C returned by different plants into the soil. So replacing mono-cropping with multiple cropping can enhance humified C fractions and can improve soil functional properties. C1 [Aziz, Irfan] PMS Arid Agr Univ, Dept Agron, Rawalpindi, Pakistan.

BARBARAE; GIANT REED; HYMENOPTERA EURYTOMIDAE; NORTH-AMERICA; RIO-GRANDE; DONAX; BRASSICACEAE; IMAGERY AB As part of a biological control program for the invasive weed, Arundo donax L., several genotypically unique populations of the parthenogenetic stem-galling wasp, Tetramesa romana Walker (Hymenoptera: Eurytomidae), from Spain and France were released in an infested riparian zone along the Rio Grande from Brownsville to Del Rio, TX. An adventive population of the wasp of unknown origin with limited distribution in Texas was also discovered, evaluated, and released as part of the program. More than 1.2 million wasps representing the mixture of genotypes were aerially released from 2009 to 2011. Wasps dispersed from their original release locations and now have a continuous distribution along the Rio Grande from Brownsville to Del Rio, and have dispersed throughout most of Central Texas with satellite populations as far west as San Angelo (Tom Green County), north as far as Kaufman (Kaufman County), and east to Navasota (Grimes County). The most successful genotype (#4) represented 390 of the 409 wasps recovered and matched both an imported population from the Mediterranean coast of Spain and an adventive population established in Texas before the start of the biological control program. Several other European genotypes of the wasp released in the program apparently failed to establish. This result demonstrated the benefits of evaluating and releasing the maximum genetic diversity of the biological control agent in the introduced range. Abundance of T. romana on the Rio Grande from Laredo to Del Rio averaged 190% more in 2013-2014 compared to a similar study in 2008-2009 before release of the European wasps. A favorability index was developed that showed that conditions from 1969 to 1977 would have been adverse to the wasp; conditions after 2009 were more favorable. Climate matching predicts the wasp will disperse throughout the southern U. S. and Mexico. C1 [Goolsby, John A.; Thomas, Donald B.] ARS, USDA, Cattle Fever Tick Res Lab, Edinburg, TX 78541 USA.

TI Thrips tabaci (Thysanoptera: Thripidae) and Iris yellow spot virus Associated with Onion Transplants, Onion Volunteers, and Weeds in Colorado SO SOUTHWESTERN ENTOMOLOGIST LA English DT Article ID NEW-YORK; HOSTS AB Infestation by onion thrips, Thrips tabaci Lindeman, was determined on transplants of onion (Allium cepa L.) received in Colorado during March and April from out-of-state sources (Imperial Valley, CA; near Phoenix, AZ; and southern Texas) during 2004 to 2008. In the 5 years of the study, 50 to 100% of the transplant lots sampled arrived infested with thrips. Among infested transplant lots, the overall number of thrips averaged 0.15 to 0.63 per plant, with as many as four per plant in some lots. T. tabaci was the dominant thrips species in all seasons and locations of transplant origin. In addition, 19 of 83 (23%) tested lots had plants positive for Iris yellow spot virus. Iris yellow spot virus and T. tabaci were detected in volunteer onion plants as early as 1 May, a few weeks after the summer onion crop was planted, suggesting a possible role of infected volunteer plants in perennation of the virus between onion crops. Iris yellow spot virus and T. tabaci were detected in many common weeds including blue mustard (Chorispora tenella (Pall.) DC), common purslane (Portulaca oleracea L.), field bindweed (Convolvulus arvensis L.), flixweed (Descurainia sophia Webb & Berth.), prickly lettuce (Lactuca serriola L.), and redroot pigweed (Amaranthus retroflexus L.) in early spring near onion fields in Colorado during 2006 to 2009. Confirmation that Iris yellow spot virus and Iris yellow spot virus-infective thrips overwintered in volunteer onions and some common winter annual and perennial weeds emphasizes that managing volunteer onions and weeds is important for management of iris yellow spot, in addition to planting transplants free of thrips and the pathogen.

Although mechanistic models are commonly applied for evaluation of climate effects for snowmelt, empirical relationships provide a first-order validation of the various postulates required for their implementation. Previous studies of empirical sensitivity for April 1 snow water equivalent (SWE) in the western United States were developed by regressing interannual variations in SWE to winter precipitation and temperature. This offers a temporal analog for climate change, positing that a warmer future looks like warmer years. Spatial analogs are used to hypothesize that a warmer future may look like warmer places, and are frequently applied alternatives for complex processes, or states/metrics that show little interannual variability (e.g., forest cover). We contrast spatial and temporal analogs for sensitivity of April 1 SWE and the mean residence time of snow (SRT) using data from 524 Snowpack Telemetry (SNOTEL) stations across the western U.S. We built relatively strong models using spatial analogs to relate temperature and precipitation climatology to snowpack climatology (April 1 SWE, R-2=0.87, and SRT, R-2=0.81). Although the poorest temporal analog relationships were in areas showing the highest sensitivity to warming, spatial analog models showed consistent performance throughout the range of temperature and precipitation. Generally, slopes from the spatial relationships showed greater thermal sensitivity than the temporal analogs, and high elevation stations showed greater vulnerability using a spatial analog than shown in previous modeling and sensitivity studies. The spatial analog models provide a simple perspective to evaluate potential futures and may be useful in further evaluation of snowpack with warming.

TI Analytical steady-state solutions for water-limited cropping systems using saline irrigation water SO WATER RESOURCES RESEARCH LA English DT Article ID ROOT-ZONE; LEACHING FRACTION; MANAGEMENT; MODEL; PLANT; SOIL; TOLERANCE; TRANSPORT; DRAINAGE; STRESS AB Due to the diminishing availability of good quality water for irrigation, it is increasingly important that irrigation and salinity management tools be able to target submaximal crop yields and support the use of marginal quality waters. In this work, we present a steady-state irrigated systems modeling framework that accounts for reduced plant water uptake due to root zone salinity. Two explicit, closed-form analytical solutions for the root zone solute concentration profile are obtained, corresponding to two alternative functional forms of the uptake reduction function. The solutions express a general relationship between irrigation water salinity, irrigation rate, crop salt tolerance, crop transpiration, and (using standard approximations) crop yield. Example applications are illustrated, including the calculation of irrigation requirements for obtaining targeted submaximal yields, and the generation of crop-water production functions for varying irrigation waters, irrigation rates, and crops. Model predictions are shown to be mostly consistent with existing models and available experimental data. Yet the new solutions possess advantages over available alternatives, including: (i) the solutions were derived from a complete physical-mathematical description of the system, rather than based on an ad hoc formulation; (ii) the analytical solutions are explicit and can be evaluated without iterative techniques; (iii) the solutions permit consideration of two common functional forms of salinity induced reductions in crop water uptake, rather than being tied to one particular representation; and (iv) the utilized modeling framework is compatible with leading transient-state numerical models.

TI What we know, and don't know, about the impact of state policy and systems-level interventions on prescription drug overdose SO DRUG AND ALCOHOL DEPENDENCE LA English DT Review DE Prescribing; Opioids; Overdose; Policy; Evaluation; Pain ID NALOXONE DISTRIBUTION PROGRAMS; CHRONIC NONCANCER PAIN; NEW-YORK-CITY; OPIOID-OVERDOSE; UNITED-STATES; BENZODIAZEPINE PRESCRIPTION; INTRANASAL NALOXONE; MONITORING PROGRAMS; CLINICAL GUIDELINES; WASHINGTON-STATE AB Background: Drug overdose deaths have been rising since the early 1990s and is the leading cause of injury death in the United States. Overdose from prescription opioids constitutes a large proportion of this burden. State policy and systems-level interventions have the potential to impact prescription drug misuse and overdose. Methods: We searched the literature to identify evaluations of state policy or systems-level interventions using non-comparative, cross-sectional, before-after, time series, cohort, or comparison group designs or randomized/non-randomized trials. Eligible studies examined intervention effects on provider behavior, patient behavior, and health outcomes. Results: Overall study quality is low, with a limited number of time-series or experimental designs. Knowledge and prescribing practices were measured more often than health outcomes (e.g., overdoses). Limitations include lack of baseline data and comparison groups, inadequate statistical testing, small sample sizes, self-reported outcomes, and short-term follow-up. Strategies that reduce inappropriate prescribing and use of multiple providers and focus on overdose response, such as prescription drug monitoring programs, insurer strategies, pain clinic legislation, clinical guidelines, and naloxone distribution programs, are promising. Evidence of improved health outcomes, particularly from safe storage and disposal strategies and patient education, is weak. Conclusions: While important efforts are underway to affect prescriber and patient behavior, data on state policy and systems-level interventions are limited and inconsistent. Improving the evidence base is a critical need so states, regulatory agencies, and organizations can make informed choices about policies and practices that will improve prescribing and use, while protecting patient health.

HYMENOPTERA; DUNG BEETLE COLEOPTERA; BUMBLEBEE NEST DENSITY; BIRD SPECIES RICHNESS AB Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - ). We make site-level summary data available alongside this article. The full database will be publicly available in 2015. C1 [Hudson, Lawrence N.; Contu, Sara; Hill, Samantha L.

The disease results in the shredding and death of leaf tissue following the rupture of elongated sod. Nearly 100 different grass species in more than 30 genera are infected by stripe smut. During the last two centuries more than 30 smut taxa have been described from members of this complex. The present study attempts to clarify the taxonomy and phylogeny of stripe smuts on grasses by analysing both morphological and molecular data. More than 200 specimens from different continents and host plants were examined. DNA was extracted from teliospores of 23 specimens from different hosts collected in Europe, Asia, and North America. The ITS and LSU regions of ribosomal DNA were amplified and used in phylogenetic analyses. The results of Maximum Parsimony and Bayesian analyses demonstrated that there are several lineages of stripe smut fungi. Analyses of morphological characters assessed with light and scanning electron microscopy showed high support for the differentiation of two clades as distinct from U. striiformis s.I., i.e., U. nunavutica sp. nov. and U. bromine. Two additional clades, U. striiformis s.str. on Holcus and a clade containing specimens from Elymus, were identified with molecular data although morphological differences were not apparent. Descriptions are given for each species. C1 [Savchenko, K. G.; Wasser, S. P.; Nevo, E.] Univ Haifa, Dept Evolutionary & Environm Biol, IL-31905 Haifa, Israel. [Savchenko, K. G.; Heluta, V.

In this study, a bio-based nanosized material, cellulose nanocrystals (CNC), extracted from southern pine pulp was employed as a reinforcing agent in a natural rubber (NR) matrix. NR/CNC nanocomposites were prepared by a solution mixing and casting method. The morphology, thermal, and mechanical properties of the nanocomposites were investigated using scanning electron microscopy, Fourier transform-infrared spectroscopy, tensile tests, dynamic mechanical analysis, thermal gravimetric analysis, and differential scanning calorimetry. The CNC displayed a gradient dispersion in the nanocomposites, and no microscaled aggregates were observed. Both the tensile strength and modulus of the nanocomposites increased with the addition of CNC, accompanied by a slight decrease in elongation at break. The storage modulus also improved with the addition of CNC, which served as good evidence of the reinforcing tendency of CNC in the NR matrix. The thermal stability of the nanocomposites showed an insignificant decrease in CNC addition. The glass transition temperature of the nanocomposites was not influenced by CNC.

Across large areas of Mexico, N fertilizers are being over-applied, resulting in lower N use efficiency. Mexico's greenhouse gas (GHG) inventory (in CO2 equivalents) reports that agricultural production contributes to about 12% of the country's emissions, with N2O-N emissions from fertilizer contributing about half of the GHG emissions from agriculture. Mexico does not have tools that can be used to assess N fertilizer use and emissions of N2O-N from organic and inorganic sources. Such tools could be used to help nutrient managers implement management practices that increase N use efficiencies and reduce N2O-N emissions. The new Nitrogen Index tier zero tool was used to assess N use efficiencies and N2O-N emissions in different cropping systems of Mexico. Mexico's current GHG inventory for agriculture just multiplies the use of N fertilizer in the country by 1% to assess national emissions of N2O. When we tested the new tier zero Nitrogen Index, it performed much better than the current methodology for calculating Mexico's N2O emissions, and N2O emissions predicted by the tool were correlated with observed values (P < 0.01). The N index tool was closer to measured values than the current method used for Mexico's GHG inventory. We propose that this prototype of the Nitrogen Index tier zero for Mexico can be used to assess the effects of cropping systems and N management practices on emissions of N2O-N in Mexico to improve the accuracy of the national inventory of N2O-N emissions in Mexico, which is reported to the United Nations Framework Convention on Climate Change (UNFCCC).

TI NUMERICAL SIMULATION OF TRANSPORT OF PARTICLES EMITTED FROM GROUND-LEVEL AREA SOURCE USING AERMOD AND CFD SO ENGINEERING APPLICATIONS OF COMPUTATIONAL FLUID MECHANICS LA English DT Article DE particle dispersion; ground-level area source; AERMOD; CFD; OpenFOAM ID BEEF-CATTLE FEEDLOT; DISPERSION MODELS; ODOR DISPERSION; EMISSION RATES; ADMS AB Fugitive sources, including animal feeding operations, can contribute significantly to particulate pollution and cause environmental and health problems. Transport of particles emitted from these sources can be simulated using atmospheric dispersion models and computational fluid dynamics (CFD). This study evaluated the capability of AERMOD, the U.S. EPA preferred dispersion model, in modeling transport of particles emitted from area sources by comparing it to CFD. The two models responded similarly to effects of atmospheric stability and wind speed. AERMOD calculated lower downwind particle concentrations than CFD. In addition, predicted particle concentrations at locations downwind of the source remained constant with height in AERMOD but varied with height in CFD. Comparison of convection and diffusion rates simulated in CFD indicated that the assumptions on transport processes in AERMOD are suitable for modeling dispersion for area sources. However, estimated values for eddy diffusivity in crosswind and vertical directions were much higher in AERMOD than in CFD, which may explain the low concentrations predicted by the dispersion model and contribute to the difference in their calculated downwind concentrations and simulated concentration profiles.

We present a framework that evaluates short- and long-term FLM predictions at site and landscape scales. Site-scale evaluation is conducted through comparing raster cell-level predictions with inventory plot data whereas landscape-scale evaluation is conducted through comparing predictions stratified by extraneous drivers with aggregated values in inventory plots. Long-term predictions are evaluated using empirical data and knowledge. We demonstrate the applicability of the framework using LANDIS PRO FLM. We showed how inventory data were used to initialize the landscape and calibrate model parameters. Evaluation of the short-term LANDIS PRO predictions based on multiple metrics showed good overall performance at site and landscape scales. The predicted long-term stand development patterns were consistent with the established theories of stand dynamics. The predicted long-term forest composition and successional trajectories conformed well to empirical old-growth studies in the region. (C) 2014 Elsevier Ltd. All rights reserved.

These features include: (i) pastures are biologically diverse so interactions between plant species must be considered; (ii) economic return requires the inclusion of the animal as an additional trophic level; (iii) interaction between the grazing animal and the pasture is complex, influenced by the environment, plant species and animal behaviour and this creates feedbacks that can result in vicious cycles; (iv) animals spatially transfer substantial amounts of nutrients both randomly and systematically and this creates or exacerbates soil variability; and (v) whole farm management is both more complex and more important to system function in grazed compared to arable systems and it is harder to capture in simulation models. These challenges complicate the process-based modelling of pastoral systems and present significant obstacles to model developers and users. Here we discuss these challenges, describe the range of solutions used by different models and discuss the strengths and weaknesses of these solutions. We have placed particular emphasis on the analysis of a range of possible solutions with the point of view that diversity between and within models is important to provide the flexibility needed for future uses. We find that for most challenges there is a diversity of solutions incorporated into the models and that there is the potential to capture additional diversity, if needed, from other models. We note an apparent lack of development in the modelling of extreme events such as very high temperatures, systematic animal-mediated nutrient transfers, pests, weeds and gene-environment interactions in pastoral simulation models and suggest that these subject areas should receive more attention.

AgMIP protocols emphasize the use of multiple models; consequently, data harmonization is essential. This interoperability was achieved by establishing a data exchange mechanism with variables defined in accordance with international standards; implementing a flexibly structured data schema to store experimental data; and designing a method to fill gaps in model-required input data. Researchers and modelers are able to use these tools to run an ensemble of models on a single, harmonized dataset. This allows them to compare models directly, leading ultimately to model improvements. An important outcome is the development of a platform that facilitates researcher collaboration from many organizations, across many countries. This would have been very difficult to achieve without the AgMIP data interoperability standards described in this paper. (C) 2014 Elsevier Ltd. All rights reserved.

Empirical generalized linear models of the largest fires (>5000 ha) across the contiguous United States (US) were developed at similar to 60 km spatial and weekly temporal resolutions using solely atmospheric predictors. Climate-fire relationships on interannual timescales were evident, with wetter conditions than normal in the previous growing season enhancing VLFs probability in rangeland systems and with concurrent long-term drought enhancing VLFs probability in forested systems. Information at sub-seasonal timescales further refined these relationships, with short-term fire weather being a significant predictor in rangelands and fire danger indices linked to dead fuel moisture being a significant predictor in forested lands. Models demonstrated agreement in capturing the observed spatial and temporal variability including the interannual variability of VLF occurrences within most ecoregions. Furthermore the model captured the observed increase in VLF occurrences across parts of the southwestern and southeastern US from 1984 to 2010 suggesting that, irrespective of changes in fuels and land management, climatic factors have become more favorable for VLF occurrence over the past three decades in some regions. Our modeling framework provides a basis for simulations of future VLF occurrences from climate projections. C1 [Barbero, R.; Abatzoglou, J. T.] Univ Idaho, Dept Geog, Moscow, ID 83843 USA. [Steel, E.

Turmeric, nutmeg, ginger, clove, oregano, cinnamon, anise, fennel, basil, black cumin, and black pepper showed antifungal activity against the plant pathogens Colletotrichum acutatum, Colletotrichum fragariae, and Colletotrichum gloeosporioides. Among the active extracts, turmeric and nutmeg were the most active and were chosen for further investigation. The bioassay-guided fractionation led to the isolation of three compounds from turmeric (1-3) and three compounds from nutmeg (4-6). Their chemical structures were elucidated by spectroscopic analysis including HR-MS, 1D, and 20 NMR as curcumin (1), demethoxycurcumin (2) and bisdemethoxy-curcumin (3), erythro-(7R,8R)-Delta(8')-4,7-dihydroxy-3,3',5'-trimethoxy-8-O-4'-neolignan (4), erythro-(7R,8R)-Delta 8'-7-acetoxy-3,4,3',5'-tetra-methoxy-8-O-4'-neolignan (5), and 5-hydroxy-eugenol (6). The isolated compounds were subsequently evaluated using a 96-well microbioassay against plant pathogens. At 30 mu M, compounds 2 and 3 possessed the most antifungal activity against Phomopsis obscurans and Phomopsis viticola, respectively. (C) 2014 Published by Elsevier B.V.

The C. lari group is currently composed of five species (C. lari, Campylobacter insulaenigrae, Campylobacter volucris, Campylobacter subantarcticus, and Campylobacter peloridis), as well as a group of strains termed the urease-positive thermophilic Campylobacter (UPTC) and other C. lari-like strains. Here we present the complete genome sequences of 11 C. lari group strains, including the five C. lari group species, four UPTC strains, and a lari-like strain isolated in this study. The genome of C. lari subsp. lari strain RM2100 was described previously. Analysis of the C. lari group genomes indicates that this group is highly related at the genome level. Furthermore, these genomes are strongly syntenic with minor rearrangements occurring only in 4 of the 12 genomes studied. The C. lari group can be bifurcated, based on the flagella and flagellar modification genes. Genomic analysis of the UPTC strains indicated that these organisms are variable but highly similar, closely related to but distinct from C. lari. Additionally, the C. lari group contains multiple genes encoding hemagglutination domain proteins, which are either contingency genes or linked to conserved contingency genes. Many of the features identified in strain RM2100, such as major deficiencies in amino acid biosynthesis and energy metabolism, are conserved across all 12 genomes, suggesting that these common features may play a role in the association of the C. lari group with coastal environments and watersheds.

TI Anaplasma marginale Superinfection Attributable to Pathogen Strains with Distinct Genomic Backgrounds SO INFECTION AND IMMUNITY LA English DT Article ID OUTER-MEMBRANE PROTEINS; ANTIGENIC VARIATION; GENETIC DIVERSITY; MOLECULAR PHYLOGENY; MAMMALIAN RESERVOIR; ANDERSONI ACARI; HIGH PREVALENCE; TRANSMISSION; RICKETTSIALES; BACTERIAL AB Strain superinfection occurs when a second pathogen strain infects a host already infected with a primary strain. The selective pressures that drive strain divergence, which underlies superinfection, and allow penetration of a new strain into a host population are critical knowledge gaps relevant to shifts in infectious disease epidemiology. In regions of endemicity with a high prevalence of infection, broad population immunity develops against Anaplasma marginale, a highly antigenically variant rickettsial pathogen, and creates strong selective pressure for emergence of and superinfection with strains that differ in their Msp2 variant repertoires. The strains may emerge either by msp2 locus duplication and allelic divergence on an existing genomic background or by introduction of a strain with a different msp2 allelic repertoire on a distinct genomic background. To answer this question, we developed a multilocus typing assay based on high-throughput sequencing of non-msp2 target loci to distinguish among strains with different genomic backgrounds. The technical error level was statistically defined based on the percentage of perfect sequence matches of clones of each target locus and validated using experimental single strains and strain pairs. Testing of A. marginale-positive samples from tropical regions where A. marginale infection is endemic identified individual infections that contained unique alleles for all five targeted loci. The data revealed a highly significant difference in the number of strains per animal in the tropical regions compared to infections in temperate regions and strongly supported the hypothesis that transmission of genomically distinct A. marginale strains predominates in high-prevalence areas of endemicity.

Human aspartyl beta-hydroxylase (HAAH) is a plasma membrane and endoplasmic reticulum protein with hydroxylation activity, which is over-expressed in many malignant neoplasms and can be detected from the sera of tumor patients. HAAH is involved in regulating tumor cell infiltration and metastasis. Escaping from immune surveillance may help tumor cell infiltration and metastasis. However, the effects of HAAH on tumor immune surveillance have not yet been investigated carefully. The present study investigated the potential use of HAAH as an immune regulator of human NK cells. We assessed the effects of recombinant HAAH (r-HAAH) on primary human NK cell morphology, viability, cytotoxicity, apoptosis, receptors expression and cytokine/cytolytic proteins production. Our results demonstrated that r-HAAH negatively affects NK cell activity in a time and dose-dependent manner. It noticeably reduces the viability of the NK cells by increasing apoptosis and necrosis via caspase signaling pathways. Moreover, r-HAAH reduces the NK cell cytotoxicity by inhibiting surface expression of NKG2D, NKp44 and IFN-gamma secretion. These findings suggest that one of the ways by which HAAH actively promotes tumor formation and proliferation is by inhibiting NK cell-surveillance activity. (C) 2014 Elsevier B.V.

Hyperspectral images were taken of healthy fruit and those with CBS symptoms or other potentially confounding peel conditions such as greasy spot, wind scar, or melanose. Spectral angle mapper (SAM) and spectral information divergence (SID) hyperspectral analysis approaches were used to classify fruit samples into two classes: CBS or non-CBS. The classification accuracy for CBS with SAM approach was 97.90%, and 97.14% with SID. The combination of hyperspectral images and two classification approaches (SID and SAM) have proven to be effective in recognizing CBS in the presence of other potentially confounding fruit peel conditions. The study result can be a reference for the non-destructive detection of fruits infected with citrus black spot. C1 [Kim, Daegwan] Asan Med Ctr, Asan Inst Life Sci, Seoul 138736, South Korea.

Mortality in greenhouse cage tests was significantly higher after three days than one day of exposure to non-weathered bait spray on bait stations and foliage, and on bait stations exposed to weather for three weeks. Mortality increased with an increase in insect exposure time, and decreased as bait spray weather exposure increased. Mortality was higher on bait stations than on olive foliage, and treated foliage showed little toxicity after 4 weeks in weather. In a commercial orchard, bait station efficacy was determined by captures of adults on yellow panel traps. Day temperatures were slightly higher on the underside of the station than top from 2 May to 10 July, similar on the top and underside 11 July to 7 August, and slightly lower on the underside from 8 August to 4 September. Fruit length increased from 0.4 on 16 May to 3 cm on 24 September and on 30 May attained 1 cm, the minimum size to produce one adult. No larvae or adults emerged from collected fruit. More adults were captured in an untreated row than a row with bait stations until 22 August and significantly so for the period ending on 11 July. Maximum adult captures occurred during 2 weeks prior to 19 September. Attract-and-kill bait stations would help reduce insecticidal applications and table olive production costs.

These declines are best documented in honey bees and are due to a combination of stressors. In particular, pesticides have been linked to decreased longevity and performance in honey bees; however, the molecular and physiological pathways mediating sensitivity and resistance to pesticides are not well characterized. We explored the impact of coumaphos and fluvalinate, the two most abundant and frequently detected pesticides in the hive, on genome-wide gene expression patterns of honey bee workers. We found significant changes in 1118 transcripts, including genes involved in detoxification, behavioral maturation, immunity, and nutrition. Since behavioral maturation is regulated by juvenile hormone III (JH), we examined effects of these miticides on hormone titers; while JH titers were unaffected, titers of methyl farnesoate (MF), the precursor to JH, were decreased. We further explored the association between nutrition- and pesticide-regulated gene expression patterns and demonstrated that bees fed a pollen-based diet exhibit reduced sensitivity to a third pesticide, chlorpyrifos. Finally, we demonstrated that expression levels of several of the putative pesticide detoxification genes identified in our study and previous studies are also upregulated in response to pollen feeding, suggesting that these pesticides and components in pollen modulate similar molecular response pathways. Our results demonstrate that pesticide exposure can substantially impact expression of genes involved in several core physiological pathways in honey bee workers. Additionally, there is substantial overlap in responses to pesticides and pollen-containing diets at the transcriptional level, and subsequent analyses demonstrated that pollen-based diets reduce workers' pesticide sensitivity. Thus, providing honey bees and other pollinators with high quality nutrition may improve resistance to pesticides. (C) 2014 Elsevier Ltd. All rights reserved.

SP (PROTOZOA: APICOMPLEXA) FROM THE AFRICAN BUFFALO (SYNCERUS CAFFER) SO JOURNAL OF PARASITOLOGY LA English DT Article ID MULTIPLE SEQUENCE ALIGNMENT; WATER-BUFFALO; BUBALUS-BUBALIS; MITOCHONDRIAL-DNA; GAME ANIMALS; FUSIFORMIS; NEURONA; MUSCLE; CATTLE; GENE AB Sarcocystis infections have been reported from the African buffalo (Syncerus caffer), but the species have not been named. Here we propose a new name Sarcocystis cafferi from the African buffalo. Histological examination of heart (92), skeletal muscle (36), and tongue (2) sections from 94 buffalos from the Greater Kruger National Park, South Africa, and a review of the literature revealed only 1 species of Sarcocystis in the African buffalo. Macrocysts were up to 12 mm long and 6 mm wide and were located in the neck muscles and overlying connective tissue. They were pale yellow; shaped like a lychee fruit stone or cashew nut; turgid or flaccid and oval to round (not fusiform). By light microscopy (LM) the sarcocyst wall was relatively thin. By scanning electron microscopy (SEM), the sarcocyst wall had a mesh-like structure with irregularly shaped villar protrusions (vp) that were of different sizes and folded over the sarcocyst wall. The entire surfaces of vp were covered with papillomatous structures. By transmission electron microscopy (TEM), the sarcocyst wall was up to 3.6 mu m thick and had highly branched villar protrusions that were up to 3 mu m long. The villar projections contained filamentous tubular structures, most of which were parallel to the long axis of the projections, but some tubules criss-crossed, especially at the base. Granules were absent from these tubules. Longitudinally cut bradyzoites were 12.1x2.7 mu m in size, had a long convoluted mitochondrion, and only 2 rhoptries. Phylogenetic analysis of 18S rRNA and cytochrome C oxidase subunit 1 (cox1) gene sequences indicated that this Sarcocystis species is very closely related to, but distinct from, Sarcocystis fusiformis and Sarcocystis hirsuta. Thus, morphological findings by LM, SEM, and TEM together with molecular phylogenetic data (from 18S rRNA and cox1) confirm that the Sarcocystis species in the African buffalo is distinct from S. fusiformis and has therefore been named Sarcocystis cafferi.

The study was conducted over a 3.5-month period (June-October 2012), during which 3 pyriproxyfen applications were conducted. Beginning 6 wk prior to the 1st pyriproxyfen spray, 10 Biogents-Sentinel (R) traps were used each week to survey the adult Ae. albopictus population at each experimental plot through the end of the study. The treatment and control plots contained specimen cups, each containing 10 laboratory-reared Ae. aegypti larvae, placed at 8, 15, and 23 m from the spray line. Emergence inhibition (EI) of 82% or greater was observed among Ae. aegypti larvae exposed to the 3 pyriproxyfen sprays. The EI of these same Ae. aegypti larvae at the 3 distances from the spray ranged from 84% to 92% and were not significantly different. Laboratory analysis of water samples taken from the larval cups independently confirmed the presence of pyriproxyfen. Similar levels of EI were achieved in Ae. aegypti and Ae. albopictus larvae when the measured field concentrations of pyriproxyfen were recreated in laboratory assays. Trap captures of wild adult Ae. albopictus were not markedly reduced following the 1st pyriproxyfen spray, perhaps due to heavy rainfall at the time and the lower rate of pyriproxyfen applied. Within 2 wk following Spray 2, however, Ae. albopictus collections from the treatment plot averaged approximately 50% of those from the control plot, and the reduction trend continued following Spray 3.

Domestic and wild canine species are reservoirs for human T. cruzi infections. The present study examined the prevalence of antibodies to T. cruzi in wild canids from the United States. Sera from 13 red foxes (Vulpes vulpes) and 263 coyotes (Canis latrans), originating in Pennsylvania and Tennessee, were assayed for antibodies to T. cruzi with immunochromatographic tests. Antibodies to T. cruzi were found in 2 of 276 (0.72%) of all wild canids tested. Both T. cruzi-positive wild canids were coyotes and represented 2 of 21 (9.52%) wild canids assayed from Tennessee. Antibodies to T. cruzi were not detected in red fox. Anti-T. cruzi antibodies were not found in any wild canids from Pennsylvania. These results suggest that coyotes are exposed to T. cruzi in Tennessee but not in Pennsylvania.

Grassland grazing exclusion was one of the experimental approaches for achieving the grand goal. Here, we evaluate the long-term regional ecological effects of grassland grazing exclusion in the Xilingol region of Inner Mongolia, China. The dynamics of grassland communities over 8 years (2004-2011) were continuously monitored at 11 research sites dominated by temperate steppe ecosystems. These sites represent the diverse landscapes of the Mongolian Plateau in the Arid, Semi-Arid, and Humid Climatic Zones that have varying precipitation levels. The community structure of degraded grasslands was found to recover quickly toward a benign state after grazing exclusion. The exclusion promoted an increase in mean plant community height, coverage, aboveground fresh biomass, and quality. The grasslands recovered fastest and most favorably in the Humid Zone followed by the Semi-Arid Zone and the Arid Zone. The increase in the aboveground biomass and vegetation height correlated significantly with the amount of total growing season precipitation. Precipitation therefore amplified the grazing exclusion effects on grassland restoration. Grazing exclusion was most effective in the relatively moist part of the study region. However, other factors such as global climate change and variability might have interacted with grazing management practices, thereby influencing the outcomes of grassland restoration efforts in Inner Mongolia.

Large-scale ecological restoration projects have been implemented around China with the goal of restoring and sustaining ecosystem services, especially in vulnerable semi-arid regions where soil and water resources are most stressed due to historic human activities. The relationships among ecosystem services are often driven by land-use changes. It is necessary to develop an applicable method to explore the relationships between ecosystem services and driving factors over time. We selected the Yanhe Basin on China's Loess Plateau as the study area, which has experienced a large-scale Grain for Green Project (GGP), and quantified four ecosystem services (soil conservation, water retention, water yield, and crop production). The results of this study show that different trends have occurred for ecosystem services during 2000-2008. We found potential tradeoffs between soil conservation and water yield. Synergies may exist among water retention and soil conservation/water yield. Two types of preconditions were pointed out in the analysis process to define the potential relationships among ecosystem service variables. The correspondence analysis was used to explore its intrinsic linkage and its variations among ecosystemservices, land uses, and spatial locations. It suggests that the intensities of the ecosystem services provided by most of land uses and the internal proportion of regulating service to provision service in a sub-basin has been changed by GGP, but the relative spatial patterns of ecosystem services are still being maintained in entire basin scale from 1980 to 2008.

It cleans fields faster and costs less in comparison to other residue removal methods. Agricultural burning, however, has been recently limited or banned during harvest seasons in China, mainly due to the air quality and human health concerns raised from its use. This paper reviews recent studies on the burning of agricultural landscapes in China to understand the natural (environmental and ecological) and human (economic and social) impacts and identifies uncertainties, gaps, and future research needs. The total annual crop straw output in China is more than 600 billon kg, with about 110, 130, and 230 billion kg coming from rice, wheat, and corn, respectively. Agricultural burning removes about one-fourth of total crop straw and emits about 140-240, 1.6-2.2, and 0.5-0.14 billion kg of CO2, PM2.5, and black carbon, respectively. Agricultural burning accounts for upto half of the total PM10 concentrations in the major burning regions during harvesting periods. Burning emissions contribute to regional haze and smog events. Therefore, limiting or banning agricultural burning is a necessary measure for reducing air pollution in China. The estimations of total burned crop straw amounts and emission factors are the major uncertainty sources for emission estimates. More studies are needed to better describe the smoke plume rise, dispersion, and interactions with weather and climate and to simulate the ecological impacts of agricultural burning. Effective alternatives need to be explored in order to provide solutions for farmers to remove agricultural residues in the wake of the burning ban.

A small subset of these Agaricomycetes, exemplified by Phlebiopsis gigantea, is capable of colonizing freshly exposed conifer sapwood despite its high content of extractives, which retards the establishment of other fungal species. The mechanism(s) by which P. gigantea tolerates and metabolizes resinous compounds have not been explored. Here, we report the annotated P. gigantea genome and compare profiles of its transcriptome and secretome when cultured on fresh-cut versus solvent-extracted loblolly pine wood. The P. gigantea genome contains a conventional repertoire of hydrolase genes involved in cellulose/hemicellulose degradation, whose patterns of expression were relatively unperturbed by the absence of extractives. The expression of genes typically ascribed to lignin degradation was also largely unaffected. In contrast, genes likely involved in the transformation and detoxification of wood extractives were highly induced in its presence. Their products included an ABC transporter, lipases, cytochrome P450s, glutathione S-transferase and aldehyde dehydrogenase. Other regulated genes of unknown function and several constitutively expressed genes are also likely involved in P. gigantea's extractives metabolism. These results contribute to our fundamental understanding of pioneer colonization of conifer wood and provide insight into the diverse chemistries employed by fungi in carbon cycling processes.

Mla alleles encode coiled-coil (CC), nucleotide binding, leucine-rich repeat (NB-LRR) receptors that trigger isolate-specific immune responses against the powdery mildew fungus, Blumeria graminis f. sp. hordei (Bgh). How Mla or NB-LRR genes in grass species are regulated at post-transcriptional level is not clear. The microRNA family, miR9863, comprises four members that differentially regulate distinct Mla alleles in barley. We show that miR9863 members guide the cleavage of Mla1 transcripts in barley, and block or reduce the accumulation of MLA1 protein in the heterologous Nicotiana benthamiana expression system. Regulation specificity is determined by variation in a unique single-nucleotide-polymorphism (SNP) in mature miR9863 family members and two SNPs in the Mla miR9863-binding site that separates these alleles into three groups. Further, we demonstrate that 22-nt miR9863s trigger the biogenesis of 21-nt phased siRNAs (phasiRNAs) and together these sRNAs form a feed-forward regulation network for repressing the expression of group I Mla alleles. Overexpression of miR9863 members specifically attenuates MLA1, but not MLA10-triggered disease resistance and cell-death signaling. We propose a key role of the miR9863 family in dampening immune response signaling triggered by a group of MLA immune receptors in barley.

Despite the vast amount of genomic data becoming available, many pressing questions remain about the nature of genetic mutations that underlie functional variation. We present the results of combining genome-wide association analysis of 41 different phenotypes in similar to 5,000 inbred maize lines to analyze patterns of high-resolution genetic association among of 28.9 million single-nucleotide polymorphisms (SNPs) and similar to 800,000 copy-number variants (CNVs). We show that genic and intergenic regions have opposite patterns of enrichment, minor allele frequencies, and effect sizes, implying tradeoffs among the probability that a given polymorphism will have an effect, the detectable size of that effect, and its frequency in the population. We also find that genes tagged by GWAS are enriched for regulatory functions and are similar to 50% more likely to have a paralog than expected by chance, indicating that gene regulation and gene duplication are strong drivers of phenotypic variation. These results will likely apply to many other organisms, especially ones with large and complex genomes like maize.

Duan, Yongping TI Genetic Diversity of Candidatus Liberibacter asiaticus Based on Two Hypervariable Effector Genes in Thailand SO PLOS ONE LA English DT Article ID INTRAGENIC TANDEM-REPEATS; REAL-TIME PCR; GREENING DISEASE; PROPHAGE GENES; CITRUS; SEQUENCE; GENOME; IDENTIFICATION; EVOLUTION; BACTERIUM AB Huanglongbing (HLB), also known as citrus greening, is one of the most destructive diseases of citrus worldwide. HLB is associated with three species of 'Candidatus Liberibacter' with 'Ca. L. asiaticus' (Las) being the most widely distributed around the world, and the only species detected in Thailand. To understand the genetic diversity of Las bacteria in Thailand, we evaluated two closely-related effector genes, lasA(I) and lasA(II), found within the Las prophages from 239 infected citrus and 55 infected psyllid samples collected from different provinces in Thailand. The results indicated that most of the Las-infected samples collected from Thailand contained at least one prophage sequence with 48.29% containing prophage 1 (FP1), 63.26% containing prophage 2 (FP2), and 19.38% containing both prophages. Interestingly, FP2 was found to be the predominant population in Las-infected citrus samples while Las-infected psyllids contained primarily FP1. The multiple banding patterns that resulted from amplification of lasAI imply extensive variation exists within the full and partial repeat sequence while the single band from lasAII indicates a low amount of variation within the repeat sequence. Phylogenetic analysis of Las-infected samples from 22 provinces in Thailand suggested that the bacterial pathogen may have been introduced to Thailand from China and the Philippines. This is the first report evaluating the genetic variation of a large population of Ca. L. asiaticus infected samples in Thailand using the two effector genes from Las prophage regions.

Over recent decades, the continuous construction of small and large dams and soil and water conservation works (i.e. contour ridges) have taken place within this watershed. However, little is known about the effect of these water-harvesting systems on the water balance components of arid or semi-arid basins. In this paper, we present the results of a study, which evaluates the impact of the contour ridges on water balance components and erosion at basin scale by using the soil and water assessment tool model (SWAT). Large dams were modelled as reservoirs, small dams as ponds and contour ridges as potholes that fill with water and increase the percolation into the aquifer. The model predicts that contour ridges produce annually a reduction of 32 and 21% in surface run-off and river discharge, respectively, and an increase in aquifer recharge of 50%. At the same time, retention of a large proportion of entrained sediment (26%) was modelled. C1 [Abouabdillah, A.; Maataoui, A.] Natl Sch Agr Meknes, Dept Agron, Meknes 50001, Morocco.

TI Potential Disconnect Between Observations of Hydrophytic Vegetation, Wetland Hydrology Indicators, and Hydric Soils in Unique Pitcher Plant Bog Habitats of the Southern Gulf Coast SO SOUTHEASTERN NATURALIST LA English DT Article ID IRIS AB The Sarracenia spp. (pitcher plant) bogs located along the southern Gulf of Mexico represent a unique natural resource characterized by endangered and endemic wetland floral communities that include a number of carnivorous plants (e.g., pitcher plants and Drosera spp. [sundews]). Despite the prevalence of obligate wetland plant species and indicators of wetland hydrology, the soils underlying this niche ecosystem often lack clear indicators of hydric soil morphology, posing challenges to wetland delineation and resource management. The National Technical Committee for Hydric Soils and an interagency team of soil scientists investigated saturated conditions and anaerobic soil conditions in pitcher plant bogs. Our results demonstrate that many of the pitcher plant-bog soils examined failed to meet an approved hydric soil indicator. Herein, we discuss potential factors preventing the formation of typical hydric soil morphologies including: low organic-matter content, high iron-concentrations, extensive bioturbation, presence of high-chroma minerals (e.g., chert), and short saturation-intervals. Our examination of soil morphology and condition in these unique and ecologically valuable habitats indicates that additional studies are required to address the apparent disconnect between observations of soils, hydrophytic vegetation, and indicators of wetland hydrology to ensure the appropriate management of these endemic natural resources.

TI Comprehensive Framework for Ecological Assessment of the Migratory Bird Habitat Initiative Following the Deepwater Horizon Oil Spill SO SOUTHEASTERN NATURALIST LA English DT Article ID MISSISSIPPI ALLUVIAL VALLEY; WETLAND RESERVE PROGRAM; HURRICANE GEORGES; SOIL; CONSERVATION; WILDLIFE; REHABILITATION; RICEFIELDS; MANAGEMENT; ABUNDANCE AB Following the Deepwater Horizon oil spill in the Gulf of Mexico in April 2010, the USDA Natural Resources Conservation Service (NRCS) established and funded the Migratory Bird Habitat Initiative (MBHI), with the goal of improving and increasing wetland habitats on private lands to benefit wintering and migrating waterbirds displaced from oil-impacted coastal wetlands. The NRCS and conservation partners provided financial and technical assistance to landowners and managers of sites enrolled in various conservation easement programs, and incorporated approximately 190,000 ha of wetlands and agricultural lands in the Mississippi Alluvial Valley (MAV) and Gulf Coast regions in the MBHI. In fall 2010, the NRCS worked with scientists and graduate students from three universities and various conservation agencies to design and implement landscape-scale evaluations of (1) the use of MBHI-managed wetlands and comparable non-MBHI wetlands by Charadri-iformes (shorebirds), Ansertforines (waterfowl), and other waterbirds; and (2) the relative effectiveness of different MBHI practices for providing habitat and food resources for migrating, resident, and wintering waterbirds. In this paper, we describe the scientific framework designed to evaluate the MBHI in improving waterbird habitats on private lands in the MAV, the Gulf Coast Prairies in Louisiana and Texas, and Gulf coastal wetlands of Mississippi and Alabama. The results of our evaluation will enhance our understanding of the influence of MBHI, other Farm Bill Conservation Initiative managed lands (e.g., Wetland Reserve Program). and selected agricultural working lands (e.g.. Oryza sativa L. [Rice] fields in southern Louisiana and Texas) on wintering and migrating waterbirds. A proactive approach that uses science to evaluate governmental conservation programs is relevant and can inform development of meaningful public policy that likely will be needed for effective delivery of future conservation programs and to justify financial incentives paid to landowners to apply best management practices.

SO THEORETICAL AND EXPERIMENTAL PLANT PHYSIOLOGY LA English DT Article DE Chlorophyll content; Photosynthesis; Photochemical efficiency ID NITROGEN CONCENTRATION; PREDICTING NITROGEN; SPAD-502 READINGS; LEAF NITROGEN; LEAVES; PLANTS; RICE; FLUORESCENCE; GROWTH; ECOPHYSIOLOGY AB This study was carried out to verify the practical use of the portable chlorophyll meter-PCM502 (PCM) in two papaya cultivars with contrasting green coloring of the leaf blade ('Golden': yellowish-green; 'Solo': dark green). The relationship was studied between the photosynthetic process and leaf nitrogen concentration, chlorophyll concentration and SPAD readings. The Portable Chlorophyll Meter (or SPAD meter) is a simple, portable, accurate, fast and inexpensive tool. Two Carica papaya L cultivars were grown in a greenhouse with 30 % interception in the photosynthetic active radiation (PAR). At 90 and 100 days after sowing (DAS), two groups of leaves from each cultivar were used for experiments. One group was considered as "young'' leaves (3rd or 4th leaf from the apex) and one group as "mature'' leaves (6th or 7th leaf from the apex). In these experimental conditions the following parameters were measured: net photosynthesis, F-v/F-m (potential maximal quantum yield of PSII), total chlorophyll concentration and leaf organic nitrogen. At SPAD values lower than 20 for 'Golden'' and 30 for 'Solo', the F-v/F-m ratios were correlated with the increase in the ratio as determined by the PCM. There were cultivar differences related to N allocation in the leaf. 'Golden' partitioned significantly less N to chlorophyll synthesis than 'Solo' at equivalent leaf N concentrations. This explains in large part the yellowish green leaf coloring of 'Golden' papaya. These cultivar differences in chlorophyll concentration were measurable with PCM technology. In contrast, at SPAD values <30 'Sunrise Solo' had a greater rate of Fv/Fm decline than 'Golden' indicating that 'Sunrise Solo' was more sensitive to damage to PSII when N was limiting. At 90 and 100 days after planting, and with adequate water availability, PCM technology was able to evaluate the total chlorophyll molecules and maximum efficiency of PSII, meaning that the equipment can be used to diagnose physiological alterations related to N metabolism.

Irrigation water has become less available in many regions due to global climate change and domestic. To confront the challenge of water utilization, there is a need to develop water-saving irrigation techniques in order to maximize crop water use efficiency. Partial rootzone drying (PRD) is a water-saving irrigation strategy that involves irrigating only part of the rootzone while leaving the other portion to dry to a predetermined level before the next irrigation. The objective of this study was to examine whether PRD affects photosynthetic capacity and growth in young sugarcane plants (48-day old). The experiment was conducted from January to April, 2011 in a greenhouse. Sugarcane mini-stalks were transplanted with divided root systems at 20 days of age into two pots. The pots were filled with soil (oxisol), sand and manure (1:1:1). The sugarcane plants were well-watered in the first 10 days after transplanting. Thereafter, the plants were exposed to three irrigation regimes:(1) Full irrigation (FI) (control); in which both soil compartments were watered to 100 % field capacity; (2) PRD; in which one soil compartment was watered to the field capacity while the other was allowed to dry for 17 days, then the plants were reirrigated; (3) no irrigation (NI); in which both compartments were allowed to dry for 17 days, then reirrigated. Net photosynthetic rate, stomatal conductance, transpiration, predawn leaf water potential, leaf area, shoot dry weight, root dry weight, root volume, and intrinsic water use efficiency were measured. PRD did not significantly reduce growth and gas exchange in comparison to FI, yet there was a 17.6 % reduction in water application. In addition, the agronomic water use efficiency was higher in PRD (4.1 g l(-1)) and FI (3.6 g l(-1)) than NI (2.9 g l-1). In this study, PRD irrigation reduced water consumption by 17.6 % with a total biomass reduction of 11.3 % as compared with fully watered plants. In conclusion, PRD may be an efficient irrigation strategy and promising for application in drought-prone regions for saving water where sugarcane is produced.

Objectives: The primary objective of this open label clinical trial is to assess the safety and tolerability of 161010 colony forming units (CFU) of LGG administered orally twice daily to elderly volunteers for 28 days. The secondary objectives were to evaluate the effects of LGG on the gastrointestinal microbiome, host immune response and plasma cytokines. Methods: Fifteen elderly volunteers, aged 66-80 years received LGG capsules containing 161010 CFU, twice daily for 28 days and were followed through day 56. Volunteers completed a daily diary, a telephone call on study days 3, 7 and 14 and study visits in the Clinical Research Center at baseline, day 28 and day 56 to determine whether adverse events had occurred. Assessments included prompted and open-ended questions. Results: There were no serious adverse events. The 15 volunteers had a total of 47 events (range 1-7 per volunteer), 39 (83%) of which were rated as mild and 40% of which were considered related to consuming LGG. Thirty-one (70%) of the events were expected, prompted symptoms while 16 were unexpected events. The most common adverse events were gastrointestinal (bloating, gas, and nausea), 27 rated as mild and 3 rated as moderate. In the exploratory analysis, the pro-inflammatory cytokine interleukin 8 decreased during LGG consumption, returning towards baseline one month after discontinuing LGG (p=0.038) while there was no difference in other pro- or anti-inflammatory plasma cytokines. Conclusions: Lactobacillus rhamnosus GG ATCC 53103 is safe and well tolerated in healthy adults aged 65 years and older.

Within the USA, the beef cattle industry loses up to an estimated 1 billion dollars a year due to BRDC. There are many contributors to BRDC, including environmental stressors and viral and/or bacterial infections. One species of bacteria in particular, Mannheimia haemolytica, is recognized as the major cause of severe fibrinonecrotic pneumonia in cattle. M. haemolytica is an opportunistic pathogen that normally populates the upper respiratory tract of cattle, and invades the lower respiratory tract in stressed and/or virally infected cattle by mechanisms that are not completely understood. However, not all M. haemolytica appear to be equally pathogenic to cattle. Thus, a test could be developed to distinguish M. haemolytica genetic subtypes by their propensity to cause respiratory disease, allowing isolation and/or treatment of cattle harboring strains with an increased propensity to cause disease. To that end, the genomes of over 300 M. haemolytica strains are being sequenced. C1 [Clawson, Michael L.] ARS, USDA, US Meat Anim Res Ctr, Clay Ctr, NE 68933 USA.

TI Asymmetric sensitivity of first flowering date to warming and cooling in alpine plants SO ECOLOGY LA English DT Article DE early spring flowering; first flowering date; global warming; midsummer flowering; temperature sensitivity; Tibetan Plateau; warming and cooling ID REPRODUCTIVE PHENOLOGY; TEMPERATURE-CHANGES; CLIMATE-CHANGE; RESPONSES; TIMES AB Understanding how flowering phenology responds to warming and cooling (i.e., symmetric or asymmetric response) is needed to predict the response of flowering phenology to future climate change that will happen with the occurrence of warm and cold years superimposed upon a long-term trend. A three-year reciprocal translocation experiment was performed along an elevation gradient from 3200 m to 3800 m in the Tibetan Plateau for six alpine plants. Transplanting to lower elevation (warming) advanced the first flowering date (FFD) and transplanting to higher elevation (cooling) had the opposite effect. The FFD of early spring flowering plants (ESF) was four times less sensitive to warming than to cooling (by -2.1 d/degrees C and 8.4 d/degrees C, respectively), while midsummer flowering plants (MSF) were about twice as sensitive to warming than to cooling (-8.0 d/degrees C and 4.9 d/degrees C, respectively). Compared with pooled warming and cooling data, warming alone significantly underpredicted 3.1 d/degrees C for ESF and overestimated 1.7 d/degrees C for MSF. These results suggest that future empirical and experimental studies should consider nonlinear temperature responses that can cause such warming-cooling asymmetries as well as differing life strategies (ESF vs. MSF) among plant species.

TI AUSTROMUSOTIMA CAMPTOZONALE ( LEPIDOPTERA: CRAMBIDAE) HERBIVORY RESULTS IN FROND AND RHIZOME MORTALITY OF THE INVASIVE FERN LYGODIUM MICROPHYLLUM (SCHIZAELES: LYGODIACEAE) SO FLORIDA ENTOMOLOGIST LA English DT Article DE Old-world climbing fern; biological control; rhizome density; chronic herbivory ID WORLD CLIMBING FERN; BIOLOGICAL-CONTROL AGENT; WHITE CLOVER; FLORIDA; WEED; GROWTH; ESTABLISHMENT; ACARIFORMES; CONNECTIONS; POPULATIONS AB Old World climbing fern, Lygodium microphyllum (Cav.) R. Br.; Schizaeles: Lygodiaceae), is among the most problematic invasive weeds in southern Florida, USA, where it smothers and displaces native vegetation. Chemical and mechanical control methods that target aerial fronds may not provide adequate control of L. microphyllum as underground rhizomes produce new fronds following treatment. Alternatively, biological control involves persistent feeding damage from introduced herbivores and may be an additional control measure for the management of the exotic weed. Herein, we hypothesized that high levels of persistent herbivory will reduce foliar biomass, kill underground rhizomes, and increase the number of other plant species. This hypothesis was tested over an 18 month period by placing 6 cages over L. microphyllum patches growing in a natural setting and repeatedly inoculating 3 of the cages with the Australian moth Austromusotima camptozonale (Hampson) (Lepidoptera: Crambidae) while the remaining 3 caged patches served as untreated controls. Growth of L. microphyllum was markedly reduced in herbivore treated patches versus untreated controls. Rhizome density and growth also decreased in herbivorycages, where rhizomes stopped producing fronds within 12 months and destructive sampling at 18 months showed complete rhizome mortality within these patches. The number of species within patches, however, remained similar among herbivory and control treatments. These findings represent the first evidence that chronic herbivory by arthropods can kill L. microphyllum rhizomes.

However, these same resources might be exploited by certain pests. Twelve species of plants known to attract parasitic Hymenoptera and Tachinidae and candidates for conservation biological control were examined for their attractiveness to Lepidoptera, a largely herbivorous order. Interception traps (Malaise traps) were erected along the wooded margin of an agricultural field. Under these traps were placed plants with flowers and controls consisting of plants without flowers and/ or no plants. Trapped Lepidoptera were counted, their wing lengths (size) measured and when possible identified to family and species. Five of the 12 plant species in flower attracted greater numbers of Lepidoptera than their control(s), and the attracted moths tended to be relatively large species. Flower depth, but not width, was correlated to attractiveness as was floral area, but not plant height. Finally the relative capacity of plants to attract both natural enemies and selected herbivores was compared. Such comparisons are useful in choosing non-crop plants for inclusion in agro-landscape modifications. C1 ARS, USDA, Ctr Med Agr & Vet Entomol, Gainesville, FL 32608 USA.

TI GEOGRAPHICAL RANGE AND LABORATORY STUDIES ON APANTELES OPUNTIARUM (HYMENOPTERA: BRACONIDAE) IN ARGENTINA, A CANDIDATE FOR BIOLOGICAL CONTROL OF CACTOBLASTIS CACTORUM (LEPIDOPTERA: PYRALIDAE) IN NORTH AMERICA SO FLORIDA ENTOMOLOGIST LA English DT Article DE Cactus moth; Apanteles; reproductive success; field occurrence; parasitoid attack rates; Wolbachia ID WOLBACHIA; RISK AB The cactus moth, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), is a pest that threatens native Opuntia spp. in North America. Control tactics developed and implemented against this invasive pest successfully eradicated the moth in Mexico and on barrier islands in the United States. However, with the cancellation of the regional management program in the United States, no control tactics are being implemented to mitigate the expansion of the moth's geographical range. Hence, an integrated approach including biological control is proposed to regulate the population of C. cactorum in North America. Field surveys of the recently described parasitoid, Apanteles opuntiarum Martinez & Berta, were carried out within the C. cactorum native range in Argentina, and laboratory studies were conducted to develop a parasitoid rearing protocol. Apanteles opuntiarum was the most common parasitoid of C. cactorum and their field distributions were similar. In the laboratory, the parasitoid's reproductive success was maximized when one or two female wasps were exposed to 30 host larvae within a 500 ml container. Laboratory reared females were less successful at parasitizing hosts than field collected females. In spite of the success achieved with laboratory rearing, male bias was observed throughout the experiments. Because this bias might be related to the presence of the reproductive parasite Wolbachia, both laboratory colony and field collected individuals were screened and Wolbachia was detected. This study provides useful field and laboratory information on (1) laboratory rearing techniques for A. opuntiarum; (2) developing host specificity test protocols for studies under quarantine conditions; and (3) selecting parasitoid populations that best match the climatic conditions present in the C. cactorum invaded areas of North America.

The serendipitous capture of Polistes metricus Say and Polistes bellicosus Cresson in traps baited with a wine/vinegar mixture for spotted wing drosophila, Drosophila suzukii (Matsumura) prompted experiments to determine the nature of the wasp response. Both wasp species were captured in subsequent field tests in traps baited with the same mixture of wine plus vinegar, and not in unbaited traps. Polistes bellicosus responses to wine, vinegar, ethanol (as a major volatile of wine), and acetic acid (as a major volatile of vinegar) were evaluated using a Y-tube olfactometer. In the olfactometer, P. bellicosus wasps were attracted to wine and not to vinegar. They also preferred wine alone to wine with vinegar, and were attracted to ethanol. Female wasps were deterred by acetic acid. In field tests comparing traps baited with wine, vinegar and a combination of the 2 materials, P. bellicosus and Polistes fuscatus (Fab.) were captured in traps baited with wine, but were not trapped with vinegar. The inclusion of vinegar with wine did not improve bait attractiveness in the field. We conclude that the paper wasp response to the D. suzukii bait of wine plus vinegar was largely the result of the wasp response to wine. This work constitutes the first demonstration of an attractive bait that can be used to trap P. bellicosus and P. metricus in situations where they are pestiferous, and suggests a potential source of a chemical attractant based on wine volatiles.

Genetic variability among field samples collected from Michigan, Mississippi, Missouri, Florida and established laboratory colonies was examined using Amplified Fragment Length Polymorphism- Polymerase Chain Reaction (AFLP-PCR). Four AFLP primer pairs generated a total of 340 molecular markers for evaluation. Results from Analysis of Molecular Variance showed that the majority of the genetic variation occurred within populations (individuals from each sample site). Nei's method indicated reduced genetic diversity in laboratory populations compared to field populations. No major differences or deficiencies were apparent among the field samples from different areas or among the laboratory reared samples. We conclude that field populations are panmictic and laboratory reared spined soldier bug could be useful as biological control agents in the field.

USDA-APHIS and the Cooperative Agricultural Pest Survey program are charged with the responsibility to monitor for this insect pest. The adult stage is the easiest to monitor using pheromone-baited traps. Traps must be easy to handle, portable and cost effective so that they can provide high quality specimens for identifiers. This study was conducted from spring through the fall in 2010 and 2011 to compare the trapping efficacy and cost-effectiveness of 4 pheromone-baited traps for male Helicoverpa moths. Over 11,600 Helicoverpa moths were captured, all identified as the corn earworm, H. zea (Boddie). The Pherocon (R) 1C "sticky" trap generally captured the fewest number of males, while equal numbers of moths were captured in a wire cone, Scentry (TM) Heliothis, and Universal (Unitrap) Moth "bucket" trap when moderate populations were present. Wire cone traps performed statistically better when high populations were present. The sticky traps captured the highest number of non-target insects, most being ants, flies, and beetles. Overall, the average corn earworm per trap vs. cost ratio for bucket traps was higher than the other traps, suggesting that more moths per dollar would be captured using these traps.

Franco. Stocking levels, species composition, and tree size in heavily and lightly defoliated stands were similar. Douglas-fir tussock moth defoliation resulted in significant Douglas-fir mortality in the heavily defoliated stands, leading to a change in dominance to ponderosa pine, Pinus ponderosa Lawson. Douglas-fir beetle, Dendroctonus pseudotsuqae Hopkins, populations increased following the defoliation event but caused less mortality, and did not differ between heavily and lightly defoliated stands. Douglas-fir tussock moth-related mortality was greatest in trees less than 15 cm dbh (diameter at 1.4 m above the ground) that grew in suppressed and intermediate canopy positions. Douglas-fir beetle-related mortality was greatest in trees larger than 15 cm dbh that grew in the dominant and co-dominant crown positions. Although both insects utilize Douglas-fir as its primary host, stand response to infestation is different. The extensive outbreak of the Douglas-fir tussock moth followed by Douglas-fir beetle activity may be associated with a legacy of increased host type growing in overstocked conditions as a result of fire exclusion.

We tested this idea by predicting potential fire behavior across a gradient of aspen dominance in northern Utah using the Forest Vegetation Simulator and the Fire and Fuels Extension. The wind speeds necessary for crowning (crown-to-crown fire spread) and torching (surface to crown fire spread) were evaluated to test the hypothesis that predicted fire behavior is influenced by the proportion of aspen in the stand. Results showed a strong effect of species composition on crowning, but only under moderate fire weather, where aspen-dominated stands were unlikely to crown or torch. Although rarely observed in actual fires, conifer-dominated stands were likely to crown but not to torch, an example of "hysteresis" in crown fire behavior. Results support the hypothesis that potential crown fire behavior varies across a gradient of aspen dominance and fire weather, where it was likely under extreme and severe fire weather, and unlikely under moderate and high fire weather. Furthermore, the "fire-proof" nature of aspen stands broke down across the gradient of aspen dominance and fire weather. C1 [DeRose, R. Justin] US Forest Serv, Rocky Mt Res Stn, Ogden, UT 84401 USA.

TI Stable resistance to Wheat streak mosaic virus in wheat mediated by RNAi SO IN VITRO CELLULAR & DEVELOPMENTAL BIOLOGY-PLANT LA English DT Article DE Wheat streak mosaic virus; Stable expression; RNAi; Transgenics ID SELECTABLE MARKER; GENE; EXPRESSION; PLANTS; IDENTIFICATION; SUPPRESSION; INTERMEDIUM; CO960293-2; VECTORS AB Wheat streak mosaic virus (WSMV) is one of the major wheat viruses found in the Great Plains of the USA. Cultural practices are the primary methods of disease management, though not fully effective. Although genetic resistance is available, it is temperature sensitive and is sometimes closely linked with traits having negative agronomic effects. Alternative approaches to viral resistance are clearly needed. RNA interference (RNAi) has been shown to play a role in viral defense response and has been successfully used as a biotechnological tool to preprogram viral resistance in transgenic plants. In this work, a portion of the coat protein of WSMV was used as a hairpin construct and was co-transformed with pAHC20-bar to elicit viral resistance. Eleven WSMV RNAi independent transgenic events were obtained. Thirteen T-1 lines were resistant as evident by the lack of viral RNA within the tissue. Beginning in the T-2 generation, single-plant lineages were selected, selfed, and evaluated for resistance and presence of the transgene until the T-5 generation. Families were then evaluated for the presence of the transgene, presence of the selectable marker, and WSMV resistance. Each of the lines in the T-5 generation were resistant to the virus. Generational selection has maintained expression of the transgene and resistance to WSMV. C1 [Cruz, Luisa F.; Rupp, Jessica L.

'Aurora' is described for the first time. Leaves were cultured for 0, 3, 6, 10, 15, or 21 d with their upper or lower surface in contact with Woody Plant Medium supplemented with 2% sucrose, vitamins, 5 mu M thidiazuron, and 0.5% Agargel. Initial signs of adventitious shoot formation were evident by 6 d and well-developed adventitious shoots were observed by 21 d. Shoot apices formed from parenchyma cells that initially proliferated from the midrib, palisade mesophyll, and epidermis adjacent to the xylem of the original veins. Shoot apices formed directly from the upper surface regardless of which leaf surface was in contact with the medium.

We evaluated possible external sources of infection by characterizing the genetic relatedness of bovine tuberculosis from a national database of reported infections, comparing strains circulating among US cattle with those of imported cattle, and farmed and wild cervids. Farmed cervids maintained a genetically distinct Mycobacterium bovis strain, and cattle occasionally became infected with this strain. In contrast, wild cervids acted as an epidemiologically distinct group, instead hosting many of the same strains found in cattle, and the data did not show a clear transmission direction. Cattle from Mexico hosted a higher overall richness of strains than US cattle, and many of those strains were found in both US and Mexican cattle. However, these two populations appeared to be well-mixed with respect to their M. bovis lineages, and higher resolution data is necessary to infer the direction of recent transmission. Overall patterns of both host and geographic distributions were highly variable among strains, suggesting that different sources or transmission mechanisms are contributing to maintaining different strains.

To date, only a few housekeeping genes have been identified and used as reference genes in tea plant. The validity of those reference genes are not clear since their expression stabilities have not been rigorously examined. To identify more appropriate reference genes for qRT-PCR studies on tea plant, we examined the expression stability of 11 candidate reference genes from three different sources: the orthologs of Arabidopsis traditional reference genes and stably expressed genes identified from whole-genome GeneChip studies, together with three housekeeping gene commonly used in tea plant research. We evaluated the transcript levels of these genes in 94 experimental samples. The expression stabilities of these 11 genes were ranked using four different computation programs including geNorm, Normfinder, BestKeeper, and the comparative Delta C-T method. Results showed that the three commonly used housekeeping genes of CsTUBULIN1, CsACINT1 and Cs18S rRNA1 together with CsUBQ1 were the most unstable genes in all sample ranking order. However, CsPTB1, CsEF1, CsSAND1, CsCLATHRIN1 and CsUBC1 were the top five appropriate reference genes for qRT-PCR analysis in complex experimental conditions.

The rhizotoxicity of heavy metals is influenced strongly by the root cell plasma membrane (PM) surface's electrical potential (Psi 0). The usually negative.0 is created by negatively charged constituents of the PM. Cations in the rooting medium are attracted to the PM surface and anions are repelled. Addition of ameliorating cations (e. g., Ca2+ and Mg2+) to the rooting medium reduces the effectiveness of cationic toxicants (e. g., Cu2+ and Pb2+) and increases the effectiveness of anionic toxicants (e. g., SeO42- and H2AsO4-). Root growth responses to ions are better correlated with ion activities at PM surfaces ({I-Z}(0)) than with activities in the bulk-phase medium ({I-Z}(b)) (IZ denotes an ion with charge Z). Therefore, electrostatic effects play a role in heavy metal toxicity that may exceed the role of site-specific competition between toxicants and ameliorants. Furthermore,.0 controls the transport of ions across the PM by influencing both {I-Z}(0) and the electrical potential difference across the PM from the outer surface to the inner surface (Em, surf). Em, surf is a component of the driving force for ion fluxes across the PM and controls ion-channel voltage gating. Incorporation of {I-Z}(0) and Em, surf into quantitative models for root metal toxicity and uptake improves risk assessments of toxic metals in the environment. These risk assessments will improve further with future research on the application of electrostatic theory to heavy metal phytotoxicity in natural soils and aquatic environments.

However, little is known about their role in the mutualistic relationship between the African weaver ant and the cashew tree. In this study, we tested the hypothesis that cashew tree volatiles from plant parts most vulnerable to herbivory viz. inflorescence, leaves, and fruits, are attractive to weaver ants. Using behavioral assays, we show that these volatiles attract weaver ants but without significant difference in preference for any of the odors. These same plant parts are associated with extra floral nectaries (EFNs') and therefore we evaluated the possibility that the ants associate the volatiles with food rewards. We found that perception of the odors was followed by a searching response that led the ants to non-volatile sugar rewards. More importantly, we observed that weaver ants spent significantly more time around the odor when it was paired to a reward. Chemical analysis of volatiles showed that the plant parts shared similarities in chemical composition, dominated by monoterpenes and sesquiterpenes. Additionally, we evaluated the attractiveness of a synthetic blend of three ocimene isomers ((E)-beta-ocimene, (Z)-beta-ocimene and allo-ocimene) identified in cashew leaf odor and shown to constitute a candidate kairomone for the cashew pest Pseudotheraptus wayi. We found that the attractiveness of the blend was dose dependent, and the response of the ants was not significantly different to that established with the crude volatiles from plant tissues. These results present new and interesting possibilities for improving weaver ant performance in cashew pest management.

An efficient monitoring trap is needed to detect and delimit new introductions and assess population densities of established infestations. Previous studies on A. glabripennis have shown that males produce a two-component aggregation pheromone that consists of a 1:1 blend of 4-(n-heptyloxy)butan-1-ol and 4-(n-heptyloxy)butanal. Moderate attraction in field trapping studies suggested that there may be additional chemical cues missing. Volatiles from male A. glabripennis were examined to identify other potential pheromone components. Gas chromatographic / electroantennographic (GC/EAD) analyses of male aerations detected a consistent EAD-active response to a previously unidentified compound. This compound was identified as (3E,6E)-alpha-farnesene. Both male and female beetles were antennally responsive to this sesquiterpene, and both sexes were attracted to it in olfactometer bioassays at different doses. When (3E,6E)-alpha-farnesene was combined with 4-(n-heptyloxy)butan-1-ol and 4-(n-heptyloxy)butanal, attraction of both sexes increased compared to assays using 4-(n-heptyloxy)butan-1-ol and 4-(n-heptyloxy)butanal alone.

Each of the two individual synthetic stereoisomers is highly attractive to male and female adults and nymphs, but is more attractive in combination and when deployed with a harlequin bug host plant. Blends of 8 stereoisomers also are highly attractive, suggesting that isomers not found in the natural pheromone are not repellent. Deployment of an inexpensive non-stereospecific synthetic pheromone holds promise for efficient trapping and/or use in trap-crops for this important pest in North America.

Herein, we describe syntheses of the remaining 10,11-epoxy-1-bisabolen-3-ols, and provide additional evidence on the assignment of relative and absolute configurations of these compounds by single-crystal X-ray crystallography of an intermediate, (3S,6R,7R,10S)-1-bisabolen-3,10,11-triol. To demonstrate the utility of this stereoisomeric library, we revisited the aggregation pheromone of the harlequin bug, Murgantia histrionica, and showed that the male-produced pheromone consists of two stereoisomers of 10,11-epoxy-1-bisabolen-3-ol. Employment of eight cis-10,11-epoxy-1-bisabolen-3-ol stereoisomeric standards, two enantioselective GC columns, and NMR spectroscopy enabled the identification of these compounds as (3S,6S,7R,10S)-10,11-epoxy-1-bisabolen-3-ol and (3S,6S,7R,10R)-10,11-epoxy-1-bisabolen-3-ol, which are produced by M. histrionica males in 1.4:1 ratio.

Field experiments were conducted in order to elucidate the relative attractiveness of the enantiomers of the alarm pheromones, 2,5-dimethyl-3-(2-methylbutyl)pyrazine and 3-methyl-2-(2-methylbutyl)pyrazine. The enantiomers tested were synthesized from commercially available (S)-2-methylbutan-1-ol or kinetically resolved (R)-2-methylbutan-1-ol, prepared using Pseudomonas cepacia lipase (PCL). Bioassays conducted in a macadamia orchard on the island of Hawaii demonstrated that W. auropunctata were preferentially attracted to the (S)-enantiomers of both alkyl pyrazines over the racemic mixtures in all experiments. To our knowledge, this is the first instance of differential attraction of ants to the enantiomers of chiral pyrazine pheromones despite many examples of these compounds in the literature. In addition, using a chiral column it was determined that (S)-2,5-dimethyl-3-(2-methylbutyl)pyrazine and (S)-3-methyl-2-(2-methylbutyl)pyrazine are the only enantiomers produced by W. auropunctata.

Approximate Bayesian computation (ABC) can help to overcome these problems, but such method requires a prior understanding of population structure over the study area, necessitating the use of alternative methods and an intense sampling design. In this study, we made inferences about the worldwide invasion history of the ladybird Harmonia axyridis by various population genetics statistical methods, using a large set of sampling sites distributed over most of the species' native and invaded areas. We evaluated the complementarity of the statistical methods and the consequences of using different sets of site samples for ABC inferences. We found that the H.axyridis invasion has involved two bridgehead invasive populations in North America, which have served as the source populations for at least six independent introductions into other continents. We also identified several situations of genetic admixture between differentiated sources. Our results highlight the importance of coupling ABC methods with more traditional statistical approaches. We found that the choice of site samples could affect the conclusions of ABC analyses comparing possible scenarios. Approaches involving independent ABC analyses on several sample sets constitute a sensible solution, complementary to standard quality controls based on the analysis of pseudo-observed data sets, to minimize erroneous conclusions. This study provides biologists without expertise in this area with detailed methodological and conceptual guidelines for making inferences about invasion routes when dealing with a large number of sampling sites and complex population genetic structures.

TI Ecotypes of an ecologically dominant prairie grass (Andropogon gerardii) exhibit genetic divergence across the US Midwest grasslands' environmental gradient SO MOLECULAR ECOLOGY LA English DT Article DE climate change; genome scan; isolation by environment; outlier analyses; restoration; tallgrass prairie ID SWITCHGRASS PANICUM VIRGATUM; RAPID CLIMATE-CHANGE; POPULATION-STRUCTURE; LOCAL ADAPTATION; BIG BLUESTEM; LANDSCAPE GENETICS; UNITED-STATES; ALLELE FREQUENCIES; NORTH-AMERICA; GLOBAL CHANGE AB Big bluestem (Andropogon gerardii) is an ecologically dominant grass with wide distribution across the environmental gradient of U.S. Midwest grasslands. This system offers an ideal natural laboratory to study population divergence and adaptation in spatially varying climates. Objectives were to: (i) characterize neutral genetic diversity and structure within and among three regional ecotypes derived from 11 prairies across the U.S. Midwest environmental gradient, (ii) distinguish between the relative roles of isolation by distance (IBD) vs. isolation by environment (IBE) on ecotype divergence, (iii) identify outlier loci under selection and (iv) assess the association between outlier loci and climate. Using two primer sets, we genotyped 378 plants at 384 polymorphic AFLP loci across regional ecotypes from central and eastern Kansas and Illinois. Neighbour-joining tree and PCoA revealed strong genetic differentiation between Kansas and Illinois ecotypes, which was better explained by IBE than IBD. We found high genetic variability within prairies (80%) and even fragmented Illinois prairies, surprisingly, contained high within-prairie genetic diversity (92%). Using Bayenv2, 14 top-ranked outlier loci among ecotypes were associated with temperature and precipitation variables. Six of seven BayeScanF(ST) outliers were in common with Bayenv2 outliers. High genetic diversity may enable big bluestem populations to better withstand changing climates; however, population divergence supports the use of local ecotypes in grassland restoration. Knowledge of genetic variation in this ecological dominant and other grassland species will be critical to understanding grassland response and restoration challenges in the face of a changing climate.

TI An Open-Source System for In Planta Gene Stacking by Bxb1 and Cre Recombinases SO MOLECULAR PLANT LA English DT Article DE transgenesis; site-specific recombination; integrase; gene targeting; transgene expression ID SITE-SPECIFIC INTEGRATION; TRANSGENIC PLANTS; PHI-C31 INTEGRASE; GENOME; DNA; EXCISION; MARKER; RICE; MINICHROMOSOMES; ARABIDOPSIS AB The rapid development of crops with multiple transgenic traits arouses the need for an efficient system for creating stacked cultivars. Most major crops rely on classical breeding to introgress the transgene from a laboratory variety to the numerous cultivars adapted to different growing regions. Even with vegetative propagated crops, genetic crosses are conducted during varietal improvement prior to vegetative cloning. The probability to assort the 'x' number of transgenic loci into a single genome may seem trivial, (1/4)(x) for a diploid species, but given the 'y' number of other nontransgenic traits that breeders also need to assemble into the same genome, the (1/4)(x+y) probability for a 'breeding stack' could quickly make the line conversion process unmanageable. Adding new transgenes onto existing transgenic varieties without creating a new segregating locus would require site-specific integration of new DNA at the existing transgenic locus. Here, we tested a recombinase-mediated gene-stacking scheme in tobacco. Sequential site-specific integration was mediated by the mycobacteriophage Bxb1 integrase-catalyzed recombination between attP and attB sites. Transgenic DNA no longer needed after integration was excised by Cre recombinase-mediated recombination of lox sites. Site-specific integration occurred in similar to 10% of the integration events, with half of those events usable as substrates for a next round of gene stacking. Among the site-specific integrants, however, a third experienced gene silencing. Overall, precise structure and reproducible expression of the sequentially added triple traits were obtained at an overall rate of similar to 3% of the transformed clones-a workable frequency for the development of commercial cultivars. Moreover, since neither the Bxb1-att nor the Cre-lox system is under patent, there is freedom to operate.

The purposes of this study were to describe the prevalence of seafood consumption and, among consumers, the amounts of seafood eaten by sex, age group, income and education level, and race-ethnicity. Data from 15,407 adults aged 19+ participating in the 2005-2010 National Health and Nutrition Examination Surveys were analyzed using methods to account for sporadic intake of seafood. Over 80% of Americans reported consuming any seafood over the past 30 days, 74% reported consuming fish, and 54% reported eating shellfish. The percentages varied by socio-demographic group. Younger age and lower income and education levels were associated with lower odds of being a seafood consumer (p < 0.0001). Among those who reported eating seafood, the average amount eaten of any seafood was 158.2 +/- 5.6 g/week. Among seafood consumers, women and individuals of lower age and education levels consumed less seafood. Approximately 80%-90% of seafood consumers did not meet seafood recommendations when needs were estimated by energy requirements. A great deal of work remains to move Americans toward seafood consumption at current recommended levels.

TI Wind Erosion Induced Soil Degradation in Northern China: Status, Measures and Perspective SO SUSTAINABILITY LA English DT Article DE soil degradation; wind erosion; northern China ID INNER-MONGOLIA; DESERTIFICATION; QUALITY; SYSTEMS AB Soil degradation is one of the most serious ecological problems in the world. In arid and semi-arid northern China, soil degradation predominantly arises from wind erosion. Trends in soil degradation caused by wind erosion in northern China frequently change with human activities and climatic change. To decrease soil loss by wind erosion and enhance local ecosystems, the Chinese government has been encouraging residents to reduce wind-induced soil degradation through a series of national policies and several ecological projects, such as the Natural Forest Protection Program, the National Action Program to Combat Desertification, the "Three Norths" Shelter Forest System, the Beijing-Tianjin Sand Source Control Engineering Project, and the Grain for Green Project. All these were implemented a number of decades ago, and have thus created many land management practices and control techniques across different landscapes. These measures include conservation tillage, windbreak networks, checkerboard barriers, the Non-Watering and Tube-Protecting Planting Technique, afforestation, grassland enclosures, etc. As a result, the aeolian degradation of land has been controlled in many regions of arid and semiarid northern China. However, the challenge of mitigating and further reversing soil degradation caused by wind erosion still remains.

However, we lack information as to which empirical detection assay most correctly measures WSC. The objective of this study was to determine which of two commonly used empirical assays was most appropriate for detection of WSC based on equivalency to results from high performance ion chromatography with pulsed amperometric detection plus soluble starch analysis (HPIC) of the water extract. Empirical analyses used were a reducing sugar assay (RSA) that uses p-hydroxybenzoic acid hydrazide-based reagent with 50:50 glucose:fructose standards, and the phenol-sulfuric acid assay (PSA) with sucrose standards. Twenty samples including cool season grasses (CSG), legume forages, non-forage feedstuffs, silages, or warm season grasses were used. Air dry samples (0.2 g) were extracted in 35 mL of deionized water for 1 h at 40 degrees C with continuous shaking. Water extracts for HPIC and RSA analyses were hydrolyzed with 0.037 M H2SO4 at 80 degrees C for 70 min. Theoretically, RSA should give essentially the same results as HPIC, excepting that RSA also detects reducing ends of unhydrolyzed molecules. PSA detects all solubilized or suspended carbohydrates. On average, RSA and PSA values were greater than those found for HPIC by 28.2 gWSC/kg dry matter (DM). The two classes of feeds that showed differences between PSA and RSA were CSG and silages. For CSG, RSA and PSA were respectively 54.1 and 20.6 g WSC/kg DM greater than HPIC; for silages differences were smaller at 8.8 and 15.9 g WSC/kg DM. CSG contain fructans, for which RSA gives higher values than does PSA. However, the elevated RSA values for CSG were in excess of differences predicted based on inflated RSA recovery values for fructose measurement (106.5% of actual). Elevated RSA values obtained for CSG suggest that interference is affecting these grasses to a greater degree than other samples. Distillers grains showed an elevated value with PSA (69.1 g WSC/kg DM greater than HPIC); this is partially explained by the inflated recovery values for glucose (128.2% of actual) noted for PSA. Neither PSA nor RSA perfectly reflected HPIC values, however PSA gave more similar values. Gross differences between RSA and HPIC for CSG are issue, particularly without clear, resolvable basis for the discrepancy. Accordingly, PSA is preferred over RSA for detection of WSC. Selection of standards to more closely reflect WSC composition could further improve accuracy. Published by Elsevier B.V. C1 USDA ARS, US Dairy Forage Res Ctr, Madison, WI 53706 USA.

TI Evaluation of prediction equations to estimate gross, digestible, and metabolizable energy content of maize dried distillers grains with solubles (DDGS) for swine based on chemical composition SO ANIMAL FEED SCIENCE AND TECHNOLOGY LA English DT Article DE Digestible energy; Dried distillers grains with solubles; Gross energy; Metabolizable energy; Prediction equations; Swine ID GROWING PIGS; DETERGENT FIBER; FINISHING PIGS; 10 SAMPLES; BONE MEAL; CORN; VARIABILITY; LABORATORIES; DIETS; NUTRIENTS AB The objective of this study was to cross-validate prediction equations to estimate the concentration of GE, DE, and ME among sources of corn distillers dried grains with solubles (DDGS) with variable chemical composition in growing pigs. Published concentrations (DM basis) of GE, CP, ether extract (EE), NDF, and total dietary fiber (TDF) along with particle size (PS, mu m), bulk density (BD, g/cm(3)) and in vivo determinations of DE and ME from 45 sources of DDGS samples were obtained from 5 published studies. Prediction equations for GE (5 equations), DE (20 equations), and ME (19 equations) from published studies were used to calculate the concentration of GE, DE, and ME among DOGS sources and compare with experimentally determined in vivo values. Each equation was evaluated using the entire data set, and data sets that excluded data from which the equation was developed (cross-validation). Equations were compared for their overall explanation of variance (R-2), precision for reduction in prediction error (PE, kcal/kg DM), and accuracy in deviation of the predicted mean from the overall observed mean (bias, kcal/kg DM). Prediction of GE concentrations among DDGS sources was poor (PE < 200 and biases > 150) despite moderate explanation of overall variance (R2 < 0.6). Therefore, we tested DE and ME equations that included GE as an input using the actual analyzed GE concentration of samples. Under this condition, the most precise (PE = 144) and accurate (bias = 19) DE equation was DE = -2,161 + (1.39 x GE) - (20.7 x NDF) - (49.3 x EE). The most precise (PE = 149) and accurate (bias = 82) ME equation was ME = - 261 + (1.05 x GE) - (7.89 x CP) + (2.47 x NDF) - (4.99 x EE). Predicting GE with equation GE = 4,583 + (50.6 x EE) - (0.1 x PS), and using this estimate in the equation of ME = -261 + (1.05 x GE) - (7.89 x CP) + (2.47 x NDF) - (4.99 x EE), resulted in moderate precision (PE = 134) and accuracy (bias = 48). Cross-validation of equations that require PS, BD, or TDF as inputs was not possible because these inputs were only measured in 1 of the 5 published studies used in this evaluation.

Methods and Results: cDNA libraries were developed from mRNA extracted from leaves of Buxus sempervirens 'Vardar Valley' and sequenced using the Illumina MiSeq system. Approximately 11.9 million base pairs of sequence data were examined and 845 genic-SSRs were identified, including 469 dinucleotide, 360 trinucleotide, seven tetranucleotide, one pentanucleotide, and eight hexanucleotide repeats. Primer pairs were designed for 71 selectively chosen genic-SSRs containing trinucleotide repeat motifs and were used to amplify the corresponding loci in 18 diverse boxwood accessions. Twenty-three primer pairs amplified polymorphic loci, with two to 10 alleles per locus. Conclusions: These novel polymorphic genic-SSR markers will aid in evaluating genetic diversity of boxwood germplasm and allow verification of hybrids and cultivars for breeding programs.

By calculating the power of the test, the suggested protocol may provide policy-relevant information, even in the event of nonsignificant findings. The main obstacle to applying this protocol has been the need to posit an explicit alternative distribution, which runs counter to the empiricist tradition of mainstream econometrics.

Borkh.) suggest that its reintroduction could enhance terrestrial carbon (C) sequestration. A suite of decomposition models was fit with decomposition data from coarse woody debris (CWD) sampled in Wisconsin and Virginia, U.S. The optimal (two-component exponential) model was integrated with generic growth curves and documented longevity and typical stem density to evaluate how CWD and biomass pools relate to decomposition. CWD decomposed faster in Wisconsin (4.3% +/- 0.3% per year) than in Virginia (0.7% +/- 0.01% per year), and downed dead wood decomposed faster (8.1% +/- 1.9% per year) than standing dead wood (0.7% +/- 0.0% per year). We predicted considerably smaller CWD pools in Wisconsin (maximum 41 +/- 23 Mg C.ha(-1)) than in Virginia (maximum 98 +/- 23 Mg C.ha(-1)) ; the predicted biomass pool was larger in the faster growing Wisconsin trees (maximum 542 +/- 58 Mg C.ha(-1)) compared with slower growing trees in Virginia (maximum 385 +/- 51 Mg C.ha(-1)). Sensitivity analysis indicated that accurate estimates of decomposition rates are more urgent in fertile locations where growth and decomposition are rapid. We conclude that the American chestnut wood is intermediate in resistance to decomposition. Due to the interrelatedness of growth and decomposition rates, CWD pool sizes likely do not depend on species alone but on how the growth and decomposition of individual species vary in response to site productivity.

TI Toward Robust Estimation of the Components of Forest Population Change SO FOREST SCIENCE LA English DT Article DE sampling forest change; spatial-temporal sample design; components of change ID INVENTORY DESIGN; CONVERSION RATES AB Multiple levels of simulation are used to test the robustness of estimators of the components of change. I first created a variety of spatial-temporal populations based on, but more variable than, an actual forest monitoring data set and then sample those populations under a variety of sampling error structures. The performance of each of four estimation approaches is evaluated when the temporal scale of the estimand of interest is 1 year while the temporal scale of observation is 1 years. Three approaches for estimating the individual components of forest change are compared over five simulated populations under four sets of sampling error structure. The performance of a modification to these approaches is shown when extraneously obtained information indicates that a deviation to the assumed population model exists. Finally, the extraneous information is incorporated into a mixed estimator, combining each of three general transition models with a single compatibility model. The first three approaches, without the incorporation of extraneous information, are compatible with large monitoring efforts that require intervention-free results. The mixed-estimation approach accounts for model assumptions that sometimes remain latent in other approaches and is amenable to the incorporation of the extraneously obtained information and to ensuring estimator compatibility. All four approaches are shown to work well when the sampling error structure is unbiased, while some notable differences in performance were observed at the temporal extremities of observation in the presence of temporal anomalies and in the presence of biased sampling error structures.

The goal of this study was to determine which topographic features influence the distribution of exposed mineral soil following wildfire in forested watersheds. In a field investigation 2 months after a simulated wildfire, ground cover was measured and a number of topographic variables, including slope, aspect, distance to streams, solar radiation, elevation, curvature, and profile curvature, were used to determine their relationships to postfire exposed mineral soil. The spatial distribution of fire effects along hill slopes was assessed using geographic information system (GIS), and a regressional relationship was derived to estimate postfire exposed mineral soil from key topographic variables, namely, aspect, solar radiation, and profile curvature. Solar radiation, aspect, and profile curvature were significantly correlated with the amount of soil exposed after the fire; however, aspect and profile curvature were the leading variables in the predictive regression model. Convex-shaped profile curvatures on south-facing slopes had higher values of exposed mineral soil than concave surfaces on north-facing slopes. These results can help land managers with decisions on prioritizing areas in need of pre- or postfire treatment. C1 [Dobre, Mariana; Wu, Joan Q.] Washington State Univ, Puyallup, WA USA.

However, the comparative adaptation (e.g., cold hardiness and growth) of American and Chinese chestnut source material in the north has been largely overlooked. We assessed first-year growth and shoot winter injury of 13 genetic sources of American chestnut and 2 sources each of Chinese chestnut and red oak (Quercus ruin L, a native competitor) under three silvicultural treatments (open, partial, and closed canopy overstories) in Vermont, USA. Seedlings grown under open canopies that provided greater access to light exhibited greater growth than seedlings grown under partial and closed canopies. However, open canopies also resulted in lower winter temperatures that increased winter injury. Chinese chestnut seedlings had significantly greater growth but experienced greater winter injury than American chestnuts, whereas red oaks generally grew the least and experienced intermediate levels of winter injury. There were also differences in growth and winter injury among American chestnut sources: seedlings from warm and moderate temperature zones (based on meteorological data recorded near source origins) grew more in height and diameter but experienced greater winter injury than seedlings from colder climates.

TI Modeling and Mapping Oak Advance Reproduction Density Using Soil and Site Variables SO FOREST SCIENCE LA English DT Article DE oak advance reproduction; oak regeneration; site factors; modeling; Quercus spp. ID EASTERN UNITED-STATES; CENTRAL APPALACHIANS; REGENERATION; FOREST; OVERSTORY; SEEDLINGS; TREE; MISSOURI; ALUMINUM; GROWTH AB Regenerating oaks (Quercus spp.) has remained a widespread and persistent problem throughout their natural range. Research shows that abundant oak advance reproduction is crucial for success. Although it is recognized that oak advance reproduction accumulation is inversely related to site quality, there has been little effort to model oak advance reproduction density as a function of measured levels of light, water, or nutrient supply. The objective of this study was to determine whether oak advance reproduction could be modeled and mapped with site variables. The study was conducted on the Sinkin Experimental Forest in southeastern Missouri in 205-ha experimental units. Vegetation and site data were collected in 1200.5-ha circular plots with nested subplots for the inventory of the midstory (0.01 ha) and reproduction (0.004 ha). Site variables included soil available water capacity, pH, photosynthetically active radiation in the understory, forest stocking, terrain shape, and slope-aspect. Oak advance reproduction abundance was related to soil acidity and available water capacity and to other site information such as slope-aspect. Models for the red oak group species generally exhibited better fit than those for the white oaks. There also was evidence that estimates of soil acidity and available water capacity can be obtained from the SSURGO database and used in these oak advance reproduction models along with other site information to generate maps of estimated oak reproduction densities. These maps could be used for planning silvicultural interventions to increase the abundance and size of oak advance reproduction before forest regeneration.

The equations were based on data from 32 Douglas-fir trees randomly selected via probability proportional to size from a single stand. Our equations were then compared with nationally generalized equations, other published and widely used Pacific Northwest equations, recent site-specific equations from southwestern Washington, and the USDA Forest Service Forest Inventory and Analysis (FIA) Program regional equations and the component-ratio method. FIA predictions for stemwood were similar to the Siskiyou estimates, predicting on average 97% of our Siskiyou equation. The FIA component ratio method compared the best to our total aboveground biomass for a 70-cm dbh tree, predicting 103% of the Siskiyou estimate. The frequently used Pacific Northwest equations predicted higher and the Washington equation lower total aboveground biomass than ours. Crown component predictions varied much more widely by as much as 3-fold. Our protocols were most similar to those used in the Washington study, offering opportunities for analysis of site-specific metadata as covariants in future biomass investigations. C1 [Nay, S.

Earlier detection of incipient forest health problems and a quantitatively rigorous assessment method is increasingly important. Here, we describe a method that is adaptable across tree species and stress agents and practical for use in the field. This approach relies on: (1) measurements covering a range of forest decline symptoms, from early decline to imminent death, (2) normalization of each measurement within each species' natural range, and (3) combining normalized measurements into one summary decline rating, thus creating a rigorous, detailed assessment of forest condition within the context of the species' typical characteristics. We demonstrate the utility of this approach in comparison to traditional field assessments of forest condition for both early detection and more sensitive monitoring over time. This comprehensive approach will allow researchers and forest managers to track subtle changes in tree condition over shorter periods of time, an imperative advancement for the detection and monitoring of invasive pests. While the case studies presented here are based on specific tree species and stress agents, this approach is scalable and broadly applicable to other tree species and stressors, making it a valuable approach for forest health monitoring and assessment.

Although a multitude of descriptive definitions for resistance and resilience exist, to evaluate whether specific management activities (silviculture) are effective, prescriptive characterizations are necessary. We introduce a conceptual framework that explicitly differentiates resistance and resilience, denotes appropriate scales, and establishes the context for evaluation structure and composition. Generally, resistance is characterized as the influence of structure and composition on disturbance, whereas resilience is characterized as the influence of disturbance on subsequent structure and composition. Silvicultural utility of the framework is demonstrated by describing disturbance-specific, time-bound structural and compositional objectives for building resistance and resilience to two fundamentally different disturbances: wildfires and spruce beetle outbreaks. The conceptual framework revealed the crucial insight that attempts to build stand or landscape resistance to spruce beetle outbreaks will ultimately be unsuccessful. This frees the silviculturist to focus on realistic goals associated with building resilience to likely inevitable outbreaks. Ultimately, because structure and composition, at appropriate scales, are presented as the standards for evaluation and manipulation, the framework is broadly applicable to many kinds of disturbance in various forest types.

Research indicates that forests can potentially minimize peak flows during storm events, yet the relationship between forests and flooding is complex. Forest roads, usually found in managed systems, can potentially magnify the effects of forest harvesting on water yields. The distributed hydrology-soil-vegetation model was successfully calibrated at an hourly time step for a 760-ha watershed in the Blue Ridge Mountains of North Carolina. The impacts of forest road density were modeled using uniform input parameters but changing road densities. Road densities tested were 0.5, 1.0, 3.0, 4.3, 6.0, and 12.0 km km(-2). Results indicate that increases in road density increased average stormflow volume by as much as 17.5% when road densities increased from 0.5 to 4.3 km km(-2) (P < 0.05). Overall, model simulations suggest that minimizing road density necessitated by the land use and appropriate forest road best management practices can be used to minimize impacts on stormflow.

Ligules, junctions at the leaf sheath and blade in grasses, protect stalks from environmental stresses and, in conjunction with auricles, controls leaf angle. Previous studies in mutants have recessive liguleless mutants (lg1 and lg2) and dominant mutations in knotted1-like homeobox genes (Lg3-O, Lg4, and Kn1) involved in ligule development. Recently, a new semidominant liguleless mutant, Liguleless narrow (Lgn-R), has been characterized in maize that affects ligule and auricle development and results in a narrow leaf phenotype. We show that quantitative genetic variation affects penetrance of Lgn-R. To examine the genetic architecture underlying Lgn-R expressivity, crosses between Lgn-R/+ mutants in a B73 background and intermated B73 x Mo17 recombinant inbred lines were evaluated in multiple years and locations. A single main-effect quantitative trait locus (QTL) on chromosome 1 (sympathy for the ligule; sol) was discovered with a Mo17-contributed allele that suppressed Lgn-R mutant phenotypes. This QTL has a genetic-interaction with a locus on chromosome 7 (lucifer; lcf) for which the B73-contributed allele increases the ability of the sol(Mo17) allele to suppress Lgn-R. Neither of the genetic intervals likely to contain sol or lcf overlap with any current liguleless genes nor with previously identified genome-wide association QTL connected to leaf architecture. Analysis of phenotypes across environments further identified a genotype by enviroment interaction determining the strength of the sol x lcf interaction.

Insights into the evolutionary processes that led to this resistance during crop domestication may be inferred from the population history of domesticated and wild rice strains. In this study, we applied a recently developed statistical method, time-dependent Poisson random field model, to examine the evolution of the Pi-ta gene in cultivated and weedy rice. Our study suggests that the Pi-ta gene may have more recently introgressed into cultivated rice, indica and japonica, and U.S. weedy rice from the wild species, O. rufipogon. In addition, the Pi-ta gene is under positive selection in japonica, tropical japonica, U.S. cultivars and U.S. weedy rice. We also found that sequences of two domains of the Pi-ta gene, the nucleotide binding site and leucine-rich repeat domain, are highly conserved among all rice accessions examined. Our results provide a valuable analytical tool for understanding the evolution of disease resistance genes in crop plants. C1 [Amei, Amei] Univ Nevada, Dept Math Sci, Las Vegas, NV 89154 USA.

As with other aquaculture species, rainbow trout and steelhead (Oncorhynchus mykiss) are susceptible to disease and outbreaks can lead to significant losses. Fish culturists have therefore been pursuing strategies to prevent losses to common pathogens such as Flavobacterium psychrophilum (the etiological agent for bacterial cold water disease [CWD]) and infectious hematopoietic necrosis virus (IHNV) by adjusting feed formulations, vaccine development, and selective breeding. However, discovery of genetic markers linked to disease resistance offers the potential to use marker-assisted selection to increase resistance and reduce outbreaks. For this study we sampled juvenile fish from 40 families from 2-yr classes that either survived or died after controlled exposure to either CWD or IHNV. Restriction site-associated DNA sequencing produced 4661 polymorphic single-nucleotide polymorphism loci after strict filtering. Genotypes from individual survivors and mortalities were then used to test for association between disease resistance and genotype at each locus using the program TASSEL. After we accounted for kinship and stratification of the samples, tests revealed 12 single-nucleotide polymorphism markers that were highly associated with resistance to CWD and 19 markers associated with resistance to IHNV. These markers are candidates for further investigation and are expected to be useful for marker assisted selection in future broodstock selection for various aquaculture programs.

Measuring sweetness, sourness, bitterness, astringency and toothetch without a sensory panel makes economic sense. This investigation compares descriptive sensory evaluation (DSE) with physical methods. Brix degree (Brix), titratable acidity (TA), pH, methyl cellulose precipitable tannin assay (MCPTA) and electronic tongue (e-tongue) techniques were measured in six commercial juices. The MCPTA correlated with astringent (r=0.57, Pr=0.01) and bitter (r=0.58, Pr=0.01), while pH negatively correlated with sour (r=-0.53, Pr=0.02). DSE and physical measurements sufficiently differentiated brands. DSE could differentiate between five of the six brands. TA, Brix, pH and MCPTA tests differentiated between all six juice brands. The e-tongue resulted in large differences within four of the brand as well as between brands. Evaluation of these methods by diluting one juice brand facilitated distinguishing how the methods work on the same compounds at declining concentrations. Practical ApplicationsThis study compares pomegranate juice chemical measures (Brix, pH, TA, MCPTA) with actual sensory taste and mouth feeling characteristics as well as introduces the e-tongue as an application to monitor quality in processed pomegranate juice. The MCPTA assay reasonably correlated with astringency and can be utilized for estimating pomegranate juice astringency in place of sensory evaluation. The information reported is useful for testing juices in research settings and in monitoring juice production for quality assurance purposes.

Unlike household surveys, not all establishments contribute equally to survey estimates. With regard to agricultural surveys, if an extremely large farm fails to complete a survey, the United States Department of Agriculture (USDA) could potentially underestimate average acres operated among other things. In order to identify likely nonrespondents prior to data collection, the USDA's National Agricultural Statistics Service (NASS) began modeling nonresponse using Census of Agriculture data and prior Agricultural Resource Management Survey (ARMS) response history. Using an ensemble of classification trees, NASS has estimated nonresponse propensities for ARMS that can be used to predict nonresponse and are correlated with key ARMS estimates.

Although fall migration patterns of North American Ospreys have been described and studied, very little has been published about the spring migration of these birds. We used satellite telemetry to: (1) determine the characteristics (timing, duration, migratory routes) of spring migrations of Ospreys; (2) determine if differences in spring migration patterns existed between sexes and among three breeding populations (east coast, midwestern, and western); and (3) compare consecutive fall and spring migrations of individual Ospreys. The median dates for departure from the wintering grounds and arrival on the breeding grounds did not differ significantly between adult male and female Ospreys. Compared to their fall migrations, all male and all east coast Ospreys spent fewer days on migration, fewer days in stopover periods along the migration route, traveled shorter distances overall, and traveled farther (on average) each day during spring. In contrast, fall and spring migration characteristics of all female and western Ospreys were similar. Our findings suggest that, although sex and breeding location might influence the spring migration strategy used by individual Ospreys, both males and females minimize the time spent on migration to ensure a timely arrival on the breeding grounds to establish or defend a nesting territory.

TI WINTERING ECOLOGY OF ADULT NORTH AMERICAN OSPREYS SO JOURNAL OF RAPTOR RESEARCH LA English DT Article DE Osprey; Pandion haliaetus; habitat use; home range; migration; wintering ecology ID SATELLITE TELEMETRY; HOME-RANGE; AUTUMN MIGRATION; AQUILA-POMARINA; ACCURACY; TRACKING; ROUTES; PERFORMANCE; BEHAVIOR; PREY AB North American Ospreys (Pandion haliaetus) typically migrate long distances to their wintering grounds in the tropics. Beyond the general distribution of their wintering range (i.e., the Caribbean, South America, and Central America), very little is known about the wintering ecology of these birds. We used satellite telemetry to determine the duration of wintering period, to examine the characteristics of wintering areas used by Ospreys, and to quantify space use and activity patterns of wintering Ospreys. Adult Ospreys migrated to wintering sites and exhibited high wintering site fidelity among years. Overall, Ospreys wintered on river systems (50.6%) more than on lakes (19.0%), and use of coastal areas was (30.4%) intermediate. Ospreys remained on their wintering grounds for an average of 154 d for males and 167 d for females. Locations of wintering Ospreys obtained via GPS-capable satellite telemetry suggest these birds move infrequently and their movements are very localized (i.e. <5 km from selected roosting areas). Sizes of home ranges and core-use areas for wintering Ospreys averaged 12.7 km(2) and 1.4 km(2), respectively. Overall, our findings suggest wintering adult North American Ospreys are very sedentary, demonstrating a pattern of limited daily movements and high fidelity to a few select locations (presumably roosts). We suggest this wintering strategy might be effective for reducing the risk of mortality and maximizing energy conservation.

Living in close proximity to humans, Ospreys often come into conflict with people and several important issues require the attention of and management by natural resource professionals. These include effects on: (1) industry (e.g., foraging at aquaculture facilities), (2) utilities (e.g., nesting on electric utility power poles and transmission towers), (3) communication networks (e.g., nesting on cellular towers), and (4) transportation systems (e.g., risks posed to human health and safety due to Osprey-aircraft collisions). Due to the Osprey's migratory and wintering habits, conflicts between Ospreys and humans are generally seasonal in nature (i.e., during the nesting season); Florida is an important exception. Creative mitigation measures (many currently being developed and evaluated) that combine effective management and monitoring will provide a better understanding of human-Osprey conflicts and ensure our successful coexistence with Osprey populations in the future.

Sex-reversed, all-male hybrid tilapia (3.72 +/- 0.08 g initial weight) were fed diets in which 30% of protein in the control diet, supplied by a combination of soybean meal (SBM) and corn meal (CM) (SBM : CM ratio = 1.8), was replaced by wheat DDGS (WtDDGS), sorghum DDGS (SDDGS), whiskey DDGS (WkDDGS), or one of three corn DDGS (CDDGS 1-3) sources (control and six experimental diets) for 10 wk. Tilapia were stocked at 30 fish per aquaria (three aquaria per diet). Growth of tilapia fed diets containing DDGS sources was similar to or better than the control diet, and no nutritional deficiencies were observed. Tilapia fed the CDDGS 2 and 3 sources showed superior weight gain. Improved growth appeared to be caused by an increase in feed intake and not due to improvements in dietary nutritional value. Hematology and immunity were not affected by DDGS source. It is concluded that DDGS from all the sources examined can be included in the diet of juvenile hybrid tilapia at about 30% as a replacement of one-third protein from SBM-CM mixture without adverse effects.

TI Mercury Accumulation in Pinus nigra (Austrian Pine) SO NORTHEASTERN NATURALIST LA English DT Article ID SOUTHWESTERN PENNSYLVANIA; ATMOSPHERIC MERCURY; VEGETATION; BIOMONITOR; FORESTS; PLANTS; FOLIAGE; MOSS AB The overall objective of this field study was to determine if Pinus nigra (Austrian Pine) could serve as a useful biomonitor to evaluate multi-year concentrations of total mercury (tHg) in vegetation within southwestern Pennsylvania. Austrian Pine has been widely planted as an ornamental, and formerly as a Christmas tree, and is now naturalized within the region. We collected needle samples annually during October 2004-2010 at 15-21 locations within a 5000-km(2) study area. Because Austrian Pine trees typically retain needles for 3 years, we collected samples from 3 needle-age groups: current year (similar to 0.5 y old in October), previous year (similar to 1.5 y old), and third-year (similar to 2.5 y old), and analyzed them for total mercury (tHg). Across all years and plots, mean tHg concentrations among the 3 needle ages were significantly (P < 0.05) different from each other. Mean tHg concentration was greatest in the 2.5-yr-old needles (25.9 +/- 3.4 ng/g), less in 1.5-yr-old needles (20.2 +/- 3.2 ng/g), and least in the 0.5-yr-old needles (11.3 +/- 2.3 ng/g). The greatest mean tHg content in the oldest needles indicates that Austrian Pine may sequester atmospheric Hg in/on its needles. Although the tHg concentrations within all 3 needle ages declined slightly during 2004-2010, downward linear trends were not significant, possibly due to the short sampling period (7 years). Needle tHg concentrations were significantly less in the northeastern portion of the study area, located farthest downwind from industrial sources of tHg, and may represent background tHg levels for conifers in the region. Results from this study suggest that any biomonitoring program involving conifers should consider needle age when developing sampling protocols. In addition, results suggest that abscised older pine needles may contribute substantially to the tHg soil burden beneath conifer stands. This is the first report from North America regarding tHg concentrations in/on various-aged Austrian Pine needles. Austrian Pine may prove useful as a biomonitor when evaluating spatiotemporal pattens of tHg accumulation within vegetation in eastern North America.

The impact of these changes on cardiovascular diseases (CVD) has been studied over the last few years and the effect of the different sources of fibre on cardiovascular risk parameters and coronary heart disease (CHD) continues to create controversy. Objective: To evaluate the association between the source of dietary fibre and the prevalence of metabolic syndrome (MetS) and other cardiovascular risk factors in a Spanish working population. Subjects and methods: The study was carried out in a sample of 1592 Spanish workers free of CVD (40-55 years old) within the Aragon Workers' Health Study (AWHS) cohort. Sociodemographic, anthropometric, clinical and biochemical data were collected. Fibre intake was assessed by means of a validated 136-items semiquantitative food-frequency questionnaire. MetS was defined by using the modified National Cholesterol Education Programme - Adult Treatment Panel III (NCEP- ATP III) definition. Results: After adjusting for possible confounding factors, we found an inverse association between insoluble fibre intake and systolic and diastolic blood pressure, total cholesterol, triglycerides, apolipoprotein B100 and ratio TG/HDL. Soluble fibre was inversely associated with triglycerides and apolipoprotein B100. Furthermore, prevalence of MetS was found to be lower (OR 0.62, 95% CI: 0.40-0.96) in those participants in the highest quartile of insoluble fibre intake. Conclusion: A higher intake of insoluble fibre could play an important role in the control and management of hypertension, lipid profile and MetS.

Global occurrences of this disease are primarily limited to tropical and subtropical regions. Treatments are available; however, patients complain of side effects. Different species of plants have been screened as a potential source of new drugs against leishmaniasis. In this study, we investigated the antileishmanial activity of cilantro (Coriandrum sativum) essential oil and its main components: (E)-2-undecenal, (E)-2-decenal, (E)-2-dodecenal, decanal, dodecanal, and tetradecanal. The essential oil of C. sativum leaves inhibits growth of Leishmani donovani promastigotes in culturewith an IC50 of 26.58 +/- 6.11 mu g/mL. The aliphatic aldehydes (E)-2-decenal (7.85 +/- 0.28 mu g/mL), (E)-2-undecenal (2.81 +/- 0.21 mu g/mL), and (E)-2-dodecenal (4.35 +/- 0.15 mu g/mL), all isolated from C. sativum essential oil, are effective inhibitors of in vitro cultures of L. donovani promastigotes. Aldehydes (E)-2-decenal, (E)-2-undecenal, and (E)-2-dodecenal were also evaluated against axenic amastigotes and IC50 values were determined to be 2.47 +/- 0.25 mu g/mL, 1.25 +/- 0.11 mu g/mL, and 4.78 +/- 1.12 mu g/mL, respectively. (E)-2-Undecenal and (E)-2-dodecenal demonstrated IC50 values of 5.65 +/- 0.19 mu g/mL and 9.60 +/- 0.89 mu g/mL, respectively, against macrophage amastigotes. These cilantro compounds showed no cytotoxicity against THP-1 macrophages.

A cross-sectional survey was conducted in Texas in 2008 and 2009 to determine beliefs about reporting cattle with clinical signs consistent with foot-and-mouth disease (FMD) either prior to (scenario 1) or during an on-going outbreak of FMD (scenario 2). Two questionnaires were developed and distributed to Texas cow-calf producers in order to evaluate their behavioral, control, and normative beliefs related to disease reporting. The context for each behavior was provided through the use of scenarios, and belief strength was measured using a 7-point Likert-like scale. Beliefs were compared across scenarios and demographic categories, and the effect of scenario on belief examined using ordinal logistic regression. Respondents agreed that reporting clinically suspect cases would have positive economic and emotional consequences; however, when an outbreak was known to be present, producers were less likely to agree with many of the positive outcomes of reporting. Important barriers to disease reporting indicated by producers included a lack of knowledge related to clinical signs of highly contagious cattle diseases and which cattle are at risk of contracting FMD. In general, beliefs about barriers to reporting did not differ based on scenario. Veterinarians and regulatory authorities were the groups perceived to most strongly expect disease reporting, regardless of the scenario. Risk education for producers related to clinical signs of reportable livestock diseases, post-reporting procedures, and an understanding of FMD introduction and spread may improve the reporting of cattle with clinical signs consistent with FMD.

A cross-sectional survey was conducted in Texas in order to determine the distribution of key beliefs about obeying movement restrictions and gathering and holding cattle for disease control purposes. Two questionnaires were developed and distributed to separate representative samples of Texas cow-calf producers, respectively. The context for each behavior was provided through the use of scenarios in the questionnaire. Belief strength was measured using a 7-point Likert-like scale. Producers surveyed were unsure about the possible negative consequences of gathering and holding their cattle when requested by authorities, suggesting a key need for communication in this area during an outbreak. Respondents identified a lack of manpower and/or financial resources to gather and hold cattle as barriers to their cooperation with orders to gather and hold cattle. Producers also expressed uncertainty about the efficacy of movement restrictions to prevent the spread of foot-and-mouth disease and concern about possible feed shortages or animal suffering. However, there are emotional benefits to complying with movement restrictions and strong social expectations of cooperation with any movement bans put in place. Published by Elsevier B.V.

While the relative contribution of these systems to muscle loss is well documented in mammals, little is known in fish species. The current study uses myotubes derived from rainbow trout myogenic precursor cells as an in vitro model of white muscle tissue. Cells were incubated in complete or serum-deprived media or media supplemented with insulin-like growth factor-1 (IGF-1) and exposed to selective proteolytic inhibitors to determine the relative contribution of the ALS and UPS to total protein degradation in myotubes in different culture conditions. Results indicate that the ALS is responsible for 30-34% and 50% of total protein degradation in myotubes in complete and serum-deprived media, respectively. The UPS appears to contribute much less to total protein degradation at almost 4% in cells in complete media to nearly 17% in serum-deprived cells. IGF-1 decreases activity of both systems, as it inhibited the upregulation of both proteolytic systems induced by serum deprivation. The combined inhibition of both the ALS and UPS reduced degradation by a maximum of 55% in serum-deprived cells, suggesting an important contribution of other proteolytic systems to total protein degradation. Collectively, these data identify the ALS as a potential target for strategies aimed at improving muscle protein retention and fillet yield through reductions in protein degradation.

Its maternal lineage included Rough Purple Chili, Garnet Chili, Early Rose, and Burbank. An incorrect but widely disseminated account attributes the origin of Russet Burbank to Colorado potato grower Lou D. Sweet, with 1914 often given as the date of introduction. However, it is likely that Russet Burbank was originally released in 1902 as May's Netted Gem by L. L. May & Co. (St. Paul MN). The names Netted Gem and Russet Burbank were used synonymously for many decades. Isoenzyme, multiplex PCR, and SNP data confirm Russet Burbank as a mutation of Burbank and do not support a seedling origin. Russet Burbank was found to be similar to Burbank in processing and nutritional characteristics. A goal of this effort is that descriptions of Russet Burbank's lineage and origins will be corrected by seed companies in lists of potato varieties and at world repositories holding Russet Burbank and its progenitors.

Sulfur deficiency is rare, but may occur in the elderly. However, a large percentage of the U.S. population is deficient in copper. The purpose of this study was to determine the range of values for sulfur and copper available in advanced potato germplasm and varieties and estimate how much genetic variation exists for these two elements. Potato breeding lines and varieties in three multisite trials were evaluated for copper and sulfur content by wet ashing and Inductively Coupled Argon Plasma Emission Spectrophotometer analysis. Stability and broad-sense heritability were determined. Among genotypes, copper content ranged from 2.0 to 4.5 ug-g(-1) DW. This was a 2.25-fold difference. In these three trials, environment was never significant, while genotype by environment interactions were always significant. Genotype was significant in two of the regional trials. Broad-sense heritabilities were estimated to be 0.0, 0.93 and 0.51 for the Tri-State, Western Regional Russet and Western Regional Red/Specialty trials, respectively. Among genotypes, sulfur content ranged from 991 to 1488 ug-g(-1) DW. The highest value was 50 % higher than the lowest. In these three trials, environment was never significant, while genotype x environment interactions were always significant. Genotype was significant in two of the regional trials. Broad-sense heritabilities were estimated to be 0.53, 0.68 and 0.88, for Tri-State, Western Regional Russet, and Western Regional Red/Specialty trials, respectively. For both sulfur and copper, selection in the Western Regional Russet and Western Regional Red/Specialty trials is likely to lead to an increase in content. Selection for sulfur in the Tri-State would result in a gain as well. These results suggest that genetic improvements could be made to potato to enhance the concentrations of these minerals.

Field studies at experiment stations in Delta Junction, Fairbanks, and Palmer, Alaska were established to determine the dose-response of weeds and above and below ground potato growth to soil-applied clopyralid or dicamba (0, 35, 70, 140, 280, and 560 g ae ha(-1)). Both Norwegian cinquefoil (Potentilla norvegica) and narrowleaf hawksbeard (Crepis tectorum) were susceptible to clopyralid with over 90 % control in Delta Junction; whereas only flixweed (Descurainia sophia) was partially controlled (70 %) with dicamba. In Palmer narrowleaf hawksbeard was controlled (87 %) with clopyralid. At Delta Junction and Fairbanks, clopyralid applied at140 g ae ha(-1) injured potatoes greater than 25 %, whereas at Palmer visual injury was greater than 25 % at 70 g ae ha(-1). Above ground dicamba injury was greater than 25 % at 140, 70, and 35 g ae ha(-1) at Delta Junction, Fairbanks and Palmer, respectively. Potato tuber production was reduced by clopyralid at rates of 35 and 140 g ae ha(-1) at Delta Junction and Palmer, respectively. At Delta Junction, dicamba did not reduce potato tuber production, however in Palmer, dicamba rates at 70 g ae ha(-1) and greater reduced potato tuber production more than 50 %. Sub-samples of potato tubers from Delta Junction and Palmer were grown out to determine if clopyralid and dicamba content in tubers would reduce subsequent growth. Dicamba at rates of 140 g ae ha(-1) or greater injured plants grown from daughter tubers and reduced shoot height, but had no effect on the number of emerged shoots. Clopyralid at all rates injured plants that emerged from daughter tubers and injury increased with increasing rate. At Palmer, clopyralid in daughter tubers rates at 140 g ae ha(-1) or greater reduced shoot height and at 280 g ae ha(-1) or greater reduced shoot number. At Delta, clopyralid in daughter tubers reduced shoot height at 280 and 560 g ae ha(-1), but had no effect on shoot number.

TI Evidence of a Monogenic Nature of the Nz Gene Conferring Resistance Against Potato virus Y Strain Z (PVYZ) in Potato SO AMERICAN JOURNAL OF POTATO RESEARCH LA English DT Article DE Potato virus Y; Potato; Hypersensitive resistance; Nz gene ID BIOLOGICAL CHARACTERIZATION; HYPERSENSITIVE RESISTANCE; MONOCLONAL-ANTIBODIES; CHROMOSOME-IV; IDENTIFICATION; POTYVIRUSES; NECROSIS; CROPS AB Hypersensitive resistance (HR) to Potato virus Y (PVY) in potato (Solanum tuberosum) is conferred by strain-specific N genes. Two such genes have been identified in potato so far, Ny (tbr) conferring HR to PVYO, and Nc (tbr) conferring HR to PVYC. A third, putative gene Nz (tbr) was proposed to confer HR against a distinct strain PVYZ. However, due to the scarcity of the PVYZ isolates of PVY, no formal proof of the monogenic nature of this new gene, Nz (tbr) , was available until now. Here, we report on a genetic study of the Nz (tbr) inheritance in three crosses between cultivars Maris Bard (Ny:Nz) and King Edward (ny:nz), and Maris Bard (Ny:Nz) and Russet Norkotah (ny:nz). A fully-sequenced PVYZ isolate, L26, was used to screen the parents and progeny for a virus-induced HR phenotype in foliage. Based on the phenotypic analysis of 203 progeny, segregation of HR phenotype in the PVYZ-infected plants was found to be 1:1, indicating a monogenic, dominant nature of the Nz (tbr) gene. Since the PVYZ strain includes PVYNTN isolates associated with tuber necrotic ringspot disease (PTNRD) in susceptible potato cultivars, the Nz (tbr) gene represents a valuable source of HR against PTNRD-inducing PVY isolates. This is the first demonstration that Nz (tbr) is a single, dominant N gene in potato conferring resistance to the PVYZ-NTN strain.

On the contrary, cultivar 'Superior' is known to have excellent tuber internal quality and moderately scab resistance. In addition, this cultivar is known to have high tuber calcium as compared to 'Atlantic'. The present study intended to generate populations that can be suitable for the genetic study of tuber calcium, internal quality, common scab, and other commercially important traits such as yield, specific gravity and chip quality at the tetraploid level. Two populations obtained by reciprocally crossing the cultivars 'Atlantic' and 'Superior' were evaluated during 2009 to 2012 at Hancock, Wisconsin. Significant genotype effects and moderately low to high broad-sense heritabilities were identified for all traits evaluated indicating that the observed phenotypic variation has an important genetic component. In addition, the parents differed significantly for all traits across trials, and most genotypes performed in between the two parents but some genotypes were more extreme than the parents. Furthermore, evidence of reciprocal effects was found for some traits. In addition to learning about the genetics of these important traits we were able to identify some genotypes that combined the commercially desired traits of the two cultivars.

AB Careful storage management is required to maintain post-harvest potato tuber quality. The plant growth regulator ethylene has well documented effects on potato tuber respiration rate, fried product color, and sprouting, but data on the amount of ethylene present in ventilated potato storages and how ethylene may affect tubers in commercial storage are not available. To address this need, ethylene concentration in ventilated commercial storage bins located in central Wisconsin was quantified using gas chromatography from shortly after bin filling until unloading. Samples of the storage atmosphere were collected approximately every other week from 17, 18 and 14 storage bins in 2010, 2011 and 2012, respectively. Ethylene was present transiently, and only rarely at concentrations greater than 20 nl l(-1). In laboratory-scale experiments, chipping potato tubers responded to ethylene at 20 nl l(-1) with an increase in tuber respiration rate, but not with an increase in post-fry chip darkening. These data indicate that the impact of atmospheric ethylene on tuber quality and storage management in ventilated potato storages is likely to be small, except near localized regions of high ethylene production.

TI Avian Influenza Virus Prevalence in Migratory Waterfowl in the United States, 2007-2009 SO AVIAN DISEASES LA English DT Article DE avian influenza virus; virus prevalence; migratory waterfowl; flyways ID A VIRUSES; WILD BIRDS; DOMESTIC TURKEYS; NORTH-AMERICA; CANADA GEESE; DUCKS; PARAMYXOVIRUSES; FLYWAY; H5N1; ASIA AB We analyzed 155,535 samples collected for surveillance of avian influenza viruses (AIVs), in the United States from 2007 to 2009, from migratory waterfowl (ducks, geese, and swans). The goal was to elucidate patterns of prevalence by flyway and functional groups to determine targets for future surveillance. Apparent prevalence of AIV was highest in the Pacific Flyway in 2007-2008 (14.2% and 14.1%, respectively), in the Mississippi Flyway in 2009 (16.8%), and lowest each year in the Atlantic Flyway (range, 7.3%-8.9%). Dabbling ducks had higher apparent prevalence of AIV (12.8%-18.8%) than diving ducks (3.9%-6.0%) or geese and swans (3.6%-3.9%). We observed highest apparent prevalence in hatch-year waterfowl (15.6%-18.9%). We further analyzed 117,738 of the 155,535 samples to test the hypothesis mallard (Anas platyrhynchos) had highest prevalence of AIV. We compared apparent prevalence and odds ratios for seven species of ducks and one species of goose commonly collected across the United States. Mallards had highest apparent prevalence (15%-26%) in half of comparisons made, whereas American green-winged teal (Anas creeca, 12%-13%), blue-winged teal (Anas discors, 13%-23%), northern pintail (Anas acuta, 16%-22%), or northern shoveler (Anas clypeata, 15%) had higher apparent prevalence in the remaining comparisons. The results of our research can be used to tailor future surveillance that targets flyways, functional groups, and species with the highest probability of detecting AIV.

We have developed a model for CD using dexamethasone (Dex) injection that suggests this disease may be related to stressors during the last stages of turkey production. Male turkeys were provided with control feed and water or with feed supplemented with a commercial yeast extract (YE) product, water supplemented with vitamin D (VD), or the combination. At 6, 11, and 15 wk of age birds were treated with three intramuscular injections of Dex over a 5-day period. Both YE and VD, but not the combination, decreased early mortality. At week 7 mortality was increased by VD, and cellulitis lesions were seen in 7/8 mortalities. Mortality at week 12 was decreased by both YE and the combination of YE and VD, and cellulitis lesions were seen in 8/17 mortalities. There were no significant differences in mortality at week 16. Total mortality was 66 birds, and 23 of these had cellulitis lesions (38%). There were no YE-treated birds with CD lesions; however, 67% of VD-treated birds had CD lesions. This study suggests that feed supplementation with YE may improve the ability of turkeys to withstand the stressors during late production and provide protection against the development of CD; however, high levels of VD supplementation may be detrimental.

The kraft lignin particles with a broad distribution ranging from large micron-to nano-sized particles were completely homogenized to nanolignin particles with sizes less than 100 nm after 4 h of mechanical shearing. The C-13 nuclear magnetic resonance (NMR) and P-31 NMR analysis showed that there were no major changes in the chemical composition between the starting kraft lignin particles and the nanolignin obtained after 4 h of mechanical treatment. The nanolignin particles did not show any change in molecular weight distribution and polydispersity compared to the original lignin particles. The nanolignin particles when used with polyvinyl alcohol (PVA) increased the thermal stability of nanolignin/PVA blends more effectively compared to the original lignin/PVA blends.

While it is clear that properly implemented fuel treatments are effective at reducing hazardous fire potential, there are ancillary ecological effects that can impact forest resilience either positively or negatively depending on the specific elements examined, as well as treatment type, timing, and intensity. In this study, we use overstory tree growth responses, measured seven years after the most common fuel treatments, to estimate forest health. Across the five species analyzed, observed mortality and future vulnerability were consistently low in the mechanical-only treatment. Fire-only was similar to the control for all species except Douglas-fir, while mechanical-plus-fire had high observed mortality and future vulnerability for white fir and sugar pine. Given that overstory trees largely dictate the function of forests and services they provide (e.g., wildlife habitat, carbon sequestration, soil stability) these results have implications for understanding longer-term impacts of common fuel treatments on forest resilience.

The potential consequences of altered climates for the structure and function of ecosystems necessitates new and complementary approaches be incorporated into traditional conservation plans. The conterminous United States of America (CONUS) has an extensive system of protected areas managed by federal agencies, but a comprehensive assessment of how this network represents CONUS climate is lacking. We present a quantitative classification of the climate space that is independent from the geographic locations to evaluate the climatic representation of the existing protected area network. We use this classification to evaluate the coverage of each agency's jurisdiction and to identify current conservation deficits. Our findings reveal that the existing network poorly represents CONUS climatic diversity. Although rare climates are generally well represented by the network, the most common climates are particularly underrepresented. Overall, 83% of the area of the CONUS corresponds to climates underrepresented by the network. The addition of some currently unprotected federal lands to the network would enhance the coverage of CONUS climates. However, to fully palliate current conservation deficits, large-scale private-land conservation initiatives will be critical.

We used a set of climate-informed state-and-transition models to explore the effects of management and natural disturbances on vegetation composition and structure under different future climates. Models were run for dry forests of central Oregon under a fire suppression scenario (i.e., no management other than the continued suppression of wildfires) and an active management scenario characterized by light to moderate thinning from below and some prescribed fire, planting, and salvage logging. Without climate change, area in dry province forest types remained constant. With climate change, dry mixed-conifer forests increased in area (by an average of 21-26% by 2100), and moist mixed-conifer forests decreased in area (by an average of 36-60% by 2100), under both management scenarios. Average area in dry mixed-conifer forests varied little by management scenario, but potential decreases in the moist mixed-conifer forest were lower with active management. With changing climate in the dry province of central Oregon, our results suggest the likelihood of sustaining current levels of dense, moist mixed-conifer forests with large-diameter, old trees is low (less than a 10% chance) irrespective of management scenario; an opposite trend was observed under no climate change simulations. However, results also suggest active management within the dry and moist mixed-conifer forests that creates less dense forest conditions can increase the persistence of larger-diameter, older trees across the landscape. Owing to projected increases in wildfire, our results also suggest future distributions of tree structures will differ from the present. Overall, our projections indicate proactive management can increase forest resilience and sustain some societal values, particularly in drier forest types. However, opportunities to create more disturbance-adapted systems are finite, all values likely cannot be sustained at current levels, and levels of resilience success will likely vary by dry province forest type. Land managers planning for a future without climate change may be assuming a future that is unlikely to exist. C1 [Halofsky, Joshua S.] Washington State Dept Nat Resources, Olympia, WA 98504 USA.

These changes will likely alter both primary productivity and plant-soil nutrient cycles. To better understand the nature of such alterations, we examined effects of groundwater availability on plant-soil nitrogen (N) cycling in areas invaded by the N-fixing phreatophyte, Prosopis pallida, on the dry leeward coast of Hawaii Island. Our aims were to quantify effects of groundwater availability to P. pallida on rates of litterfall N inputs and accretion in soils and to quantify effects of groundwater availability on N mineralization and leaching rates of inorganic N under natural rainfall conditions and simulated rain events. Stem water O-18 values indicate that P. pallida trees in lowland plots accessed shallow groundwater, while in upland plots they relied solely on rainfall. During drought periods, P. pallida at upland plots experienced water stress, evidenced by lower stem water potentials, higher water-use efficiency, and lower predawn photosynthetic performance than at lowland plots. Prosopis pallida basal area was 5.3 times greater at lowland plots, and these plots exhibited 17 times higher carbon (C), 24 times higher N, and 35 times higher phosphorus (P) additions via litterfall, indicating that productivity of this phreatophyte was decoupled from rainfall where groundwater was present. Total N mass in soils was 4.7 times greater where groundwater was accessible, supporting the case that groundwater access increased N-2 fixation at a stand level. In contrast, N mineralization and leaching losses from soils, though substantially greater in lowland relative to upland areas, were strongly controlled by rainfall. Results provide clear examples of how invasive species with particular functional attributes (i.e., N-fixing phreatophytes) exploit otherwise inaccessible resources to dramatically alter the functioning of the systems they invade and how anthropogenic changes to hydrological processes can also alter ecosystem-level impacts of biological invasions. Results also illustrate a mechanism by which regional groundwater drawdown may reduce soil nutrient accretion and availability in arid regions.

However, as a result of climate change, disturbance frequency is expected to increase in the future in many regions. It is not yet clear how such changes might affect forest ecosystems, and which mechanisms contribute to (current and future) disturbance resilience. We studied a 6364-ha landscape in the western Cascades of Oregon, USA, to investigate how patches of remnant old-growth trees (as one important class of biological legacies) affect the resilience of forest ecosystems to disturbance. Using the spatially explicit, individual-based, forest landscape model iLand, we analyzed the effect of three different levels of remnant patches (0%, 12%, and 24% of the landscape) on 500-year recovery trajectories after a large, high-severity wildfire. In addition, we evaluated how three different levels of fire frequency modulate the effects of initial legacies. We found that remnant live trees enhanced the recovery of total ecosystem carbon (TEC) stocks after disturbance, increased structural complexity of forest canopies, and facilitated the recolonization of late-seral species (LSS). Legacy effects were most persistent for indicators of species composition (still significant 500 years after disturbance), while TEC (i.e., a measure of ecosystem functioning) was least affected, with no significant differences among legacy scenarios after 236 years. Compounding disturbances were found to dampen legacy effects on all indicators, and higher initial legacy levels resulted in elevated fire severity in the second half of the study period. Overall, disturbance frequency had a stronger effect on ecosystem properties than the initial level of remnant old-growth trees. A doubling of the historically observed fire frequency to a mean fire return interval of 131 years reduced TEC by 10.5% and lowered the presence of LSS on the landscape by 18.1% on average, demonstrating that an increase in disturbance frequency (a potential climate change effect) may considerably alter the structure, composition, and functioning of forest landscapes. Our results indicate that live tree legacies are an important component of disturbance resilience, underlining the potential of retention forestry to address challenges in ecosystem management.

TI Biomass growth response to spatial pattern of variable-retention harvesting in a northern Minnesota pine ecosystem SO ECOLOGICAL APPLICATIONS LA English DT Article DE aggregated retention; biomass growth; dispersed retention; Pinus resinosa; planted seedlings; residual trees; tree regeneration; variable-retention harvesting ID GREEN-TREE RETENTION; DOUGLAS-FIR FORESTS; RED PINE; OVERSTORY RETENTION; PACIFIC-NORTHWEST; RADIAL GROWTH; REGENERATION; STANDS; OREGON; OAK AB Variable-retention harvesting (VRH) is an approach for sustaining complex structure in managed forests. A criticism of VRH is that ecological benefits may come at a cost of reduced growth of regeneration, due to competition with residual trees. However, the spatial pattern of retention, i.e., dispersed or aggregated, in VRH systems can be manipulated to minimize suppression of regeneration, and resource limitation to regeneration might be mitigated by reduction of woody shrubs. Continued growth of the residual cohort will compensate for growth reduction of regeneration, although this may differ with retention pattern. We examined aboveground whole-stand biomass growth of trees in a VRH experiment in Pinus resinosa forest in Minnesota, USA. Treatments included dispersed retention, aggregated retention, and an uncut control, as well as a shrub treatment (reduced density or ambient). We addressed the following hypotheses: (1) biomass growth of a cohort of planted pine seedlings will be highest with aggregated rather than dispersed retention, (2) biomass growth of the planted seedlings will increase with shrub reduction, and (3) biomass growth of the residual overstory will be higher with dispersed rather than aggregated retention. Aboveground biomass growth of the planted pines ranged from 0.4 kgha(-1)yr(-1) in the overstory-control-ambient-shrub treatment to 23 kgha(-1)yr(-1) in the aggregated-retention-shrub-reduction treatment. The difference between the control and the retention treatments was significant (P < 0.0001), but not between dispersed and aggregated retention (P = 0.97). Thus, our first hypothesis was not supported. In all treatments, biomass growth was significantly higher (>100% increase) with shrub reduction (P = 0.001), supporting our second hypothesis. Biomass growth of residual trees ranged from 2404 kgha(-1)yr(-1) in the uncut-control-ambient-shrub treatment to 1043 kgha(-1)yr(-1) in the aggregated-retention-shrub-reduction treatment. Differences were significant between the control and retention treatments (P = 0.003), and marginally higher with dispersed vs. aggregated retention (P = 0.09), lending support to our third hypothesis. Our results suggest that managers have flexibility in application of VRH and can expect similar stand-level biomass growth of planted regeneration regardless of retention pattern, but somewhat higher stand-level biomass growth of retained trees with dispersed retention.

TI Inter-relationships of cotton plant height, canopy width, ground cover and plant nitrogen status indicators SO FIELD CROPS RESEARCH LA English DT Article DE Proximal sensing ID DRIP IRRIGATED COTTON; LEAF NITROGEN; SCENE REFLECTANCE; CHLOROPHYLL METER; STRESSED COTTON; BIOMASS; GROWTH; YIELD; PREDICTION; MANAGEMENT AB Petiole-NO3, leaf N and chlorophyll (SPAD) meter readings are good in-season indicators of the N status of the uppermost part of cotton (Gossypium hirsutum L) plants. Petiole-NO3, particularly is widely used in the USA as an in-season plant N test that guides N fertilizer recommendations in cotton. However, these N status indicators do not take account of plant biomass, canopy width or percent cover. The objectives of this study were to assess the effect of N fertilizer rates on the commonly used indicators of plant N status; leaf N, petiole sap NO3 and chlorophyll meter (SPAD) readings and the plant growth measurements; plant height, canopy width, and percent ground cover, and determine to inter-correlations among the them. Irrigated field studies were conducted at Lubbock, TX USA in 2010 and 2011, New Deal, TX in 2010, and at Halfway, TX in 2011. Zero-N and a full N fertilizer rate of 134,101, and 112 kg N ha(-1) were used at Lubbock, New Deal, and Halfway, respectively. The 2010 cotton growing season in West Texas was much wetter than average, and the 2011 season was much drier than normal. As a result, plant height, canopy width, and ground cover were greater in the 2010 sites than in 2011. The effects of N fertilizer were greatest for the two cultivars in subsurface drip irrigation (SDI) at New Deal in 2010 for all three N status indicators, and for the three plant growth measures compared to the other site-years. Correlation analysis indicated that among the three plant N indicators, leaf N was the most sensitive to plant parameters. These effects were positive in 2010 and negative in the 2011 dry year. Petiole NO3 was the plant N indicator that was the most insensitive to plant growth, but the marked seasonal decline pattern reduces its usefulness for late-season N management.

As a global staple crop with considerable variation in kernel carotenoid composition, maize (Zea mays L.) could have a widespread impact. We performed a genome-wide association study (GWAS) of quantified seed carotenoids across a panel of maize inbreds ranging from light yellow to dark orange in grain color to identify some of the key genes controlling maize grain carotenoid composition. Significant associations at the genome-wide level were detected within the coding regions of zep1 and lut1, carotenoid biosynthetic genes not previously shown to impact grain carotenoid composition in association studies, as well as within previously associated lcyE and crtRB1 genes. We leveraged existing biochemical and genomic information to identify 58 a priori candidate genes relevant to the biosynthesis and retention of carotenoids in maize to test in a pathway-level analysis. This revealed dxs2 and lut5, genes not previously associated with kernel carotenoids. In genomic prediction models, use of markers that targeted a small set of quantitative trait loci associated with carotenoid levels in prior linkage studies were as effective as genome-wide markers for predicting carotenoid traits. Based on GWAS, pathway-level analysis, and genomic prediction studies, we outline a flexible strategy involving use of a small number of genes that can be selected for rapid conversion of elite white grain germplasm, with minimal amounts of carotenoids, to orange grain versions containing high levels of provitamin A.

In this study, we developed VE delivery systems, which were stabilized by Capsul (R) (MS), a starch modified with octenyl succinic anhydride. Influences of interfacial tension, VE viscosity, molecular weight distribution, and surfactant type (MS versus Tween 80) on stability and droplet size obtained by high-pressure homogenization were investigated. Both surfactants reduced interfacial tension and small droplet diameters (< 350 nm) were produced at high VE content (80% oil phase, w/w) and low emulsifier (2.5%, w/w), which was attributed to their molecular distribution and interfacial characteristics and the magnitude of disruptive forces generated within homogenizer. MS nanoemulsions were stable to droplet coalescence at high temperature-short time exposure (30, 55, 80 degrees C; 30 min). Results indicated that MS can be used successfully to stabilize VE nanoemulsions at ambient temperatures. Such nanoemulsions may be incorporated in many food products.

The results showed that both extraction temperature and water-material ratio had significant effects on the proanthocyanidins content, but the yield was significantly affected only by temperature. The moderate temperature and water-material ratio were beneficial to maintain high proanthocyanidins scavenging activity and good product quality. The second-order extraction and Arrhenius kinetic models were developed and successfully used to predict the proanthocyanidins yield for given conditions tested. Extraction temperature of 60 degrees C, water-material ratio of 30: 1 g g(-1), and time of 10 min are recommended for proanthocyanidins extraction from pomegranate peel, which corresponded to the highest yield of 40.6 mg g(-1) and content of 89.1 mg g(-1) having a scavenging activity of 31.5 g g(-1), and an attractive reddish yellow color.

In this paper, we discuss examples of that legacy as applied to conventional and molecular approaches to breeding for insect resistance. We also discuss the application of genetics in pest management, systematics, and ecology. Conventional breeding for insect resistance is likely to continue to lag behind other traits as the realities of the high costs associated with a conventional breeding program and complexity of the sugarcane genome will continue to hold sway. Molecular breeding techniques offer many opportunities to overcome those limitations; however, the cost associated with this technology is high and gains that are obtained in pest management must be compared to more conventional strategies. Additionally, before the release of transgenic sugarcane with insect resistance can occur, various scientific, legislative, and public perception issues must be addressed. Many sugarcane industries lack the resources and are simply unable to overcome these obstacles. Genetic methods have revolutionised insect taxonomy and provided the means for rapid identification of closely related species, often without access to identified specimens. This is now impacting on our understanding of the ecology and biology of sugarcane pests and their natural enemies. Crop plants and pest insects can be genetically modified but paratransgenesis of closely associated microorganisms may allow better targeting and delivery of insecticidal compounds. Again, scientific, legislative, and public perception issues must be addressed. C1 [White, William H.] ARS, USDA, Sugarcane Res Unit, Houma, LA 70360 USA.

The marks tested included three different concentrations of egg albumin from chicken egg white, casein from bovine milk and trypsin inhibitor from soy milk. The cadaver and free-roaming beetle treatments served to measure the acquisition and retention of each protein treatment regime by direct contact with the spray solution and by residual contact with protein-marked residue on alfalfa, respectively. In addition, the vertical distribution of marking efficacy was determined by sampling alfalfa plant tissue and beetle cadavers that were located on the upper and lower portion of the plant canopy. The data indicated that the backpack spray apparatus was very effective at uniformly administering the various protein marks, regardless of the concentration, throughout the entire plant canopy. Also, the free-roaming beetles readily self-marked by contact exposure to protein-treated plants. We also identified concentrations of each protein type that will mark about 90% of the resident beetle population. Moreover, if a mark-capture-type study only requires two unique protein marks, we determined that concentrations of 25% for egg white and 100% for bovine milk could be used to mark 98% of the population. Our results provide a significant step towards standardizing protein immunomarking protocols for insect mark-capture dispersal research. In addition, we identify several areas of research that are needed to further standardize the protein mark-capture procedure. C1 [Hagler, J. R.; Naranjo, S. E.; Machtley, S.

The combination of the sex pheromone of both species (PH combo lure) significantly increased G.molesta and marginally decreased C.pomonella captures as compared with captures of each species with either of their sex pheromones alone. The addition of a HPV combination lure [(E,Z)-2,4-ethyl decadienoate plus (E)--ocimene] or acetic acid used alone or together did not significantly increase the catch of either species in traps with the PH combo lure. The Ajar trap baited with terpinyl acetate and brown sugar (TAS bait) caught significantly more G.molesta than the delta trap baited with PH combo plus acetic acid in California during 2012. The addition of a PH combo lure to an Ajar trap significantly increased catches of G.molesta compared to the use of the TAS bait or PH combo lure alone in 2013. Female G.molesta were caught in TAS-baited Ajar traps at similar levels with or without the use of additional lures. Ajar traps baited with the TAS bait alone or with (E)--ocimene and/or PH combo lures caught significantly fewer C.pomonella than delta traps with sex pheromone alone. Ajar traps with 6.4-mm screened flaps caught similar numbers of total and female G.molesta as similarly baited open Ajar traps, and with a significant reduction in the catch of non-targets. Broader testing of HPV and PH combo lures for G.molesta in either delta or screened or open Ajar traps is warranted. C1 [Knight, A.] Agr Res Serv Wapato, Yakima Agr Res Lab, USDA, Wapato, WA USA.

Part I: Temperature SO JOURNAL OF CLIMATE LA English DT Article ID CENTRAL UNITED-STATES; AMERICAN TELECONNECTION PATTERN; NORTH-ATLANTIC OCEAN; DECADAL VARIABILITY; SUMMERTIME PRECIPITATION; ANTHROPOGENIC AEROSOLS; SOUTHERN-OSCILLATION; WAVELET ANALYSIS; WARMING HOLE; US AB The optimal ranking regime (ORR) method was used to identify intradecadal to multidecadal (IMD) time windows containing significant ranking sequences in U.S. climate division temperature data. The simplicity of the ORR procedure's output-a time series' most significant nonoverlapping periods of high or low rankings-makes it possible to graphically identify common temporal breakpoints and spatial patterns of IMD variability in the analyses of 102 climate division temperature series. This approach is also applied to annual Atlantic multidecadal oscillation (AMO) and Pacific decadal oscillation (PDO) climate indices, a Northern Hemisphere annual temperature (NHT) series, and divisional annual and seasonal temperature data during 1896-2012. In addition, Pearson correlations are calculated between PDO, AMO, and NHT series and the divisional temperature series. Although PDO phase seems to be an important influence on spring temperatures in the northwestern United States, eastern temperature regimes in annual, winter, summer, and fall temperatures are more coincident with cool and warm phase AMO regimes. Annual AMO values also correlate significantly with summer temperatures along the Eastern Seaboard and fall temperatures in the U.S. Southwest. Given evidence of the abrupt onset of cold winter temperatures in the eastern United States during 1957/58, possible climate mechanisms associated with the cause and duration of the eastern U.S. warming hole period-identified here as a cool temperature regime occurring between the late 1950s and late 1980s-are discussed.

Part II: Precipitation and Streamflow SO JOURNAL OF CLIMATE LA English DT Article ID CONTINENTAL UNITED-STATES; SEA-SURFACE TEMPERATURE; NORTH-AMERICAN DROUGHT; ATLANTIC-OCEAN; ENSO TELECONNECTIONS; DECADAL VARIABILITY; WARMING HOLE; YORK-CITY; PACIFIC; US AB In Part I of this paper, the optimal ranking regime (ORR) method was used to identify intradecadal to multidecadal (IMD) regimes in U.S. climate division temperature data during 1896-2012. Here, the method is used to test for annual and seasonal precipitation regimes during that same period. Water-year mean streamflow rankings at 125 U.S. Hydro-Climatic Data Network gauge stations are also evaluated during 1939-20 11. The precipitation and streamflow regimes identified are compared with ORR-derived regimes in the Pacific decadal oscillation (PDO), the Atlantic multidecadal oscillation (AMO), and indices derived from gridded SST anomaly (SSTA) analysis data. Using a graphic display approach that allows for the comparison of IMD climate regimes in multiple time series, an interdecadal cycle in western precipitation is apparent after 1980, as is a similar cycle in northwestern streamflow. Before 1980, IMD regimes in northwestern streamflow and annual precipitation are in approximate antiphase with the PDO. One of the clearest IMD climate signals found in this analysis are post-1970 wet regimes in eastern U.S streamflow and annual precipitation, as well as in fall [September-November (SON)] precipitation. Pearson correlations between time series of annual and seasonal precipitation averaged over the eastern United States and SSTA analysis data show relatively extensive positive correlations between warming tropical SSTA and increasing fall precipitation. The possible Pacific and northern Atlantic roots of the recent eastern U.S. wet regime, as well as the general characteristics of U.S. climate variability in recent decades that emerge from this analysis and that of Part I, are discussed.

Spore load is a commonly used criterion to describe the intensity of Nosema infection. In this study, by providing Nosema-infected bees with sterilized pollen, we confirmed that pollen feeding increased the spore loads of honey bees by several times either in the presence or absence of a queen. By changing the amount of pollen consumed by bees in cages, we showed that spore loads increased with an increase in pollen consumption. Nosema infections decrease honey bee longevity and transcription of vitellogenin, either with or without pollen feeding. However, the reduction of pollen consumption had a greater impact on honey bee longevity and vitellogenin level than the increase of spore counts caused by pollen feeding. These results indicate that spore loads may not be used alone as a direct indicator of the severity of N. ceranae infection in honey bees.

TI Influence of Nest Box Color and Release Sites on Osmia lignaria (Hymenoptera: Megachilidae) Reproductive Success in a Commercial Almond Orchard SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE Osmia lignaria; dispersal; honey bee; mason bee; orchard pollination ID SOLITARY BEE; NATIVE BEES; PROPINQUA CRESSON; FIELD EXPERIMENTS; APPLE ORCHARDS; APIS-MELLIFERA; POLLINATOR; VISION; DISCRIMINATION; ULTRAVIOLET AB Intensively managed, commercial orchards offer resources for managed solitary bees within agricultural landscapes and provide a means to study bee dispersal patterns, spatial movement, nest establishment, and reproduction. In 2012, we studied the impact of 1) the color of nest boxes covaried with four nest box density treatments and 2) the number of bee release sites covaried with two nest box density treatments on the reproductive success of Osmia lignaria Say in a California almond orchard pollinated by a mixture of O. lignaria and Apis mellifera L. Nest box color influenced the number of nests, total cells, and cells with male and female brood. More nests and cells were produced in light blue nest boxes than in orange or yellow nest boxes. The covariate nest box density also had a significant effect on brood production. The number of release sites did not affect O. lignaria nesting and reproduction, but the number of cavities in nest boxes influenced reproduction. Overall, the color of nest boxes and their distribution, but not the number of release sites, can greatly affect O. lignaria nest establishment and reproductive success in a commercial almond orchard. The ability to locate nesting sites in a homogenous, large orchard landscape may also be facilitated by the higher frequency of nest boxes with low numbers of cavities, and by the ability to detect certain nest box colors that best contrast with the blooming trees.

TI Degree-Day Benchmarks for Sparganothis sulfureana (Lepidoptera: Tortricidae) Development in Cranberries SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE cranberry IPM; degree-day; developmental model; phenology; sparganothis fruitworm AB Sparganothis sulfureana Clemens is a severe pest of cranberries in the Midwest and northeast United States. Timing for insecticide applications has relied primarily on calendar dates and pheromone trap-catch; however, abiotic conditions can vary greatly, rendering such methods unreliable as indicators of optimal treatment timing. Phenology models based on degree-day (DD) accrual represent a proven, superior approach to assessing the development of insect populations, particularly for larvae. Previous studies of S. sulfureana development showed that the lower and upper temperature thresholds for larval development were 10.0 and 29.9 degrees C (49.9 and 85.8 degrees F), respectively. We used these thresholds to generate DD accumulations specific to S. sulfureana, and then linked these DD accumulations to discrete biological events observed during S. sulfureana development in Wisconsin and New Jersey cranberries. Here, we provide the DDs associated with flight initiation, peak flight, flight termination, adult life span, preovipositional period, ovipositional period, and egg hatch. These DD accumulations represent key developmental benchmarks, allowing for the creation of a phenology model that facilitates wiser management of S. sulfureana in the cranberry system.

Feeding experiments demonstrated that bed bugs were innately susceptible to this fungus. However, only at 98% humidity were mortality rates high, regardless of whether bed bugs were sprayed with a fungal solution or contacted a treated surface. Mortality in treated bed bugs at ambient humidity did not increase when these bed bugs were kept in aggregation with other bed bugs that had recently blood fed to repletion. Based on these laboratory studies, we conclude that M. anisopliae is a poor pathogen for use in control of bed bugs, particularly at humidities that would likely be encountered under field conditions.

However, the mechanism for the loss of plant resistance under heat stress remains to be determined. In this study, we determined polar lipid profiles in control and Hessian fly-infested resistant and susceptible wheat seedlings with and without heat stress using an automated electrospray ionization tandem mass spectrometry analysis. Heat stress, alone or in combination with Hessian fly infestation, caused significant reduction in the abundance of total detected polar lipids and double bond index. Changes in lipid profiles in 'Molly' were similar to those in 'Newton' under heat stress. However, changes in lipid profiles in Molly were significantly different from those in Newton following Hessian fly infestation. The combination of heat stress and Hessian fly infestation resulted in unique lipid profiles in comparison with those in plants either treated with heat stress or infested with Hessian fly alone. In addition, a greater impact on lipid metabolism was observed in heat-stressed plants infested with Hessian fly than that in plants treated with either heat stress or Hessian fly alone. Our results suggest that changes in lipid metabolism caused by heat stress may be part of the metabolic pathways through which heat stress suppresses resistance of wheat plants to Hessian fly infestation.

A vertical flow aerosol exposure chamber that generated a standardized particle size diameter was used for these trials. In the first experiments, adults were exposed in the chamber for 2.5-45 min to aerosol dispensed at a volumetric median particle size diameter (VMD) of 16 mu m, and then held in the arenas in which they were exposed or transferred to new arenas with or without a flour food source. All adults were initially knocked down when removed from the chamber. Recovery from knockdown decreased as exposure interval increased, but the presence of a food source enhanced recovery at the lower exposure intervals. In the second experiment, the aerosol was applied at a VMD of 2 mu m and adults were exposed for between 5 and 75 min. Knockdown of adults was <= 10% when adults were removed from the chamber regardless of exposure time and afterward there was essentially complete recovery of adults. In the third and final experiment, the same 2-mu m VMD particle size and exposure times were used, but the concentration of aerosol was increased by approximate to 4 X compared with the previous experiment. In this test, initial knockdown was greater at the higher exposure intervals, but by 3 and 4 d posttreatment, recovery was again essentially 100%. This is the first published test assessing the efficacy of specific aerosol particle sizes on a stored product insect. Results indicate that particle size was a more important factor in conferring toxicity than the actual concentration or number of aerosol particles.

TI Aquatic Invertebrate Abundance and Biomass in Arkansas, Mississippi, and Missouri Bottomland Hardwood Forests During Winter SO JOURNAL OF FISH AND WILDLIFE MANAGEMENT LA English DT Article DE forested wetland; greentree reservoir; invertebrate; waterfowl ID ALLUVIAL VALLEY; WOOD DUCKS; FEMALE MALLARDS; WASTE RICE; WATERFOWL; WETLANDS; ENERGY; ACORNS; FOODS; DIET AB The Mississippi Alluvial Valley once had extensive bottomland hardwood forests, but less than 25% of the original area remains. Impounded bottomland hardwood forests, or greentree reservoirs, and naturally flooded forests are important sources of invertebrate or other prey for waterfowl, but no previous studies of invertebrate abundance and biomass have been at the scale of the Mississippi Alluvial Valley. Additionally, the Lower Mississippi Valley Joint Venture of the North American Waterfowl Management Plan requires precise, contemporary estimates of invertebrate biomass in hardwood bottomlands to determine potential foraging carrying capacity of these habitats for wintering ducks. We used sweep nets to collect aquatic invertebrates from four physiographically disjunct hardwood bottomlands in the Mississippi Alluvial Valley and Mississippi's Interior Flatwoods region during winters 2008-2010. Invertebrate abundance varied inversely with water depth in both early and late winter, with greatest abundances in depths ranging from 10 to 20 cm. The estimate of invertebrate biomass in naturally flooded forests of the Mississippi Alluvial Valley for both years combined was 18.39 kg(dry)/ha (coefficient of variation [CV] = 15%). When we combined data across regions, sites, greentree reservoirs and naturally flooded forests, and years, the estimate of mean invertebrate biomass decreased to 6.6 kg/ha but precision increased to CV = 9%. We recommend the Lower Mississippi Valley Joint Venture adopt 18.39 kg(dry)/ha as a revised estimate for invertebrate biomass for naturally flooded forests, because this estimate is reasonably precise and less than 2% of remaining hardwood bottomland is impounded greentree reservoirs in the Mississippi Alluvial Valley. Additionally, we recommend managing to invoke dynamic flooding regimes in greentree reservoirs to mimic natural flood events and provide maximal coverage of depths less than 30 cm to facilitate foraging ducks' access to nektonic and benthic invertebrates, acorns, and other natural seeds.

TI The Importance of Assessing Climate Change Vulnerability to Address Species Conservation SO JOURNAL OF FISH AND WILDLIFE MANAGEMENT LA English DT Article DE California and Southwest US; conservation; vertebrates; vulnerability assessment ID EXTINCTION RISK; GLOBAL CHANGE; BIODIVERSITY; FUTURE; DISTRIBUTIONS; CONSEQUENCES; RESTORATION; UNCERTAINTY; PREDICTIONS; PROJECTIONS AB Species conservation often prioritizes attention on a small subset of "special status" species at high risk of extinction, but actions based on current lists of special status species may not effectively moderate biodiversity loss if climate change alters threats. Assessments of climate change vulnerability may provide a method to enhance identification of species at risk of extinction. We compared climate change vulnerability and lists of special status species to examine the adequacy of current lists to represent species at risk of extinction in the coming decades. The comparison was made for terrestrial vertebrates in a regionally important management area of the southwestern United States. Many species not listed as special status were vulnerable to increased extinction risk with climate change. Overall, 74% of vulnerable species were not included in lists of special status and omissions were greatest for birds and reptiles. Most special status species were identified as additionally vulnerable to climate change impacts and there was little evidence to indicate the outlook for these species might improve with climate change, which suggests that existing conservation efforts will need to be intensified. Current special status lists encompassed climate change vulnerability best if climate change was expected to exacerbate current threats, such as the loss of wetlands, but often overlooked climate-driven threats, such as exceeding physiological thresholds.

TI EVALUATION OF CURRENT INDUSTRY PRACTICES FOR MAINTAINING TOMATO DUMP TANK WATER QUALITY DURING PACKINGHOUSE OPERATIONS SO JOURNAL OF FOOD PROCESSING AND PRESERVATION LA English DT Article ID FRESH-CUT VEGETABLES; PRODUCE WASH; CHLORINE CONCENTRATION; SALMONELLA-MONTEVIDEO; PROCESSING CONDITIONS; CROSS-CONTAMINATION; ROMAINE LETTUCE; UNITED-STATES; DISINFECTION; EFFICACY AB Maintenance of adequate sanitizer levels in tomato dump tanks is critical to preventing pathogen survival and transfer, and internalization in the fruit. However, the rapid accumulation of organic matter in dump tanks can cause a significant decline in sanitizer concentration, thus leaving wash solutions vulnerable to becoming a reservoir for pathogens. This study investigated the dynamic changes in wash water quality and sanitizer concentration during routine operations of three medium to large tomato packinghouses in Florida in 2010 and 2011. Overall, water quality declined continuously during packinghouse operations, as exhibited by significant increases in chemical oxygen demand and turbidity. Free chlorine concentration, oxidation reduction potential and pH fluctuated largely as a consequence of periodic addition of sodium hypochlorite and citric acid, and the rapid loss of free chlorine caused by organic matter. Although the packinghouses differed significantly in system configuration, operation and chlorine dosing rates, at least 25mg/L of free chlorine concentrations were maintained in all of the dump tanks surveyed. Practical ApplicationsWash water quality and sanitizer strength are important factors influencing food safety of tomatoes washed in packinghouses. Soil, debris and juices from damaged fruits entering dump tanks along with tomatoes can cause water quality and sanitizer strength to decline dramatically, leaving wash solutions vulnerable to the growth of harmful bacteria. Maintenance of adequate sanitizer levels in tomato dump tanks is critical to reducing pathogen survival, transmission and incidence of internalization in the fruit. The researchers surveyed the water quality and sanitizer concentrations during routine operations of three major tomato packinghouses in Florida in 2010 and 2011. The results are useful for the regulatory agency and tomato industry in developing packinghouse handling guidelines to maintain the quality and food safety of tomatoes.

This article examines the influence of remotely sensed soil moisture and snow depth retrievals toward improving estimates of drought through data assimilation. Soil moisture and snow depth retrievals from a variety of sensors (primarily passive microwave based) are assimilated separately into the Noah land surface model for the period of 1979-2011 over the continental United States, in the North American Land Data Assimilation System (NLDAS) configuration. Overall, the assimilation of soil moisture and snow datasets was found to provide marginal improvements over the open-loop configuration. Though the improvements in soil moisture fields through soil moisture data assimilation were barely at the statistically significant levels, these small improvements were found to translate into subsequent small improvements in simulated streamflow. The assimilation of snow depth datasets were found to generally improve the snow fields, but these improvements did not always translate to corresponding improvements in streamflow, including some notable degradations observed in the western United States. A quantitative examination of the percentage drought area from root-zone soil moisture and streamflow percentiles was conducted against the U.S. Drought Monitor data. The results suggest that soil moisture assimilation provides improvements at short time scales, both in the magnitude and representation of the spatial patterns of drought estimates, whereas the impact of snow data assimilation was marginal and often disadvantageous.

Here, simulated streamflows using the Variable Infiltration Capacity (VIC) model at coarse (degrees) spatial resolutions were evaluated against observed streamflows from 217 watersheds. In particular, the adequacy of VIC simulations in groundwater- versus runoff-dominated watersheds using a range of flow metrics relevant for water supply and aquatic habitat was examined. These flow metrics were 1) total annual streamflow; 2) total fall, winter, spring, and summer season streamflows; and 3) 5th, 25th, 50th, 75th, and 95th flow percentiles. The effect of climate on model performance was also evaluated by comparing the observed and simulated streamflow sensitivities to temperature and precipitation. Model performance was evaluated using four quantitative statistics: nonparametric rank correlation , normalized Nash-Sutcliffe efficiency NNSE, root-mean-square error RMSE, and percent bias PBIAS. The VIC model captured the sensitivity of streamflow for temperature better than for precipitation and was in poor agreement with the corresponding temperature and precipitation sensitivities derived from observed streamflow. The model was able to capture the hydrologic behavior of the study watersheds with reasonable accuracy. Both total streamflow and flow percentiles, however, are subject to strong systematic model bias. For example, summer streamflows were underpredicted (PBIAS = -13%) in groundwater-dominated watersheds and overpredicted (PBIAS = 48%) in runoff-dominated watersheds. Similarly, the 5th flow percentile was underpredicted (PBIAS = -51%) in groundwater-dominated watersheds and overpredicted (PBIAS = 19%) in runoff-dominated watersheds. These results provide a foundation for improving model parameterization and calibration in ungauged basins.

It acts in regulation and modulation of many physiological and behavioral processes through G-protein-coupled receptors. Five 5-HT receptor subtypes have been reported in Drosophila that share high similarity with mammalian 5-HT1A, 5-HT1B, 5-HT2A, 5-HT2B, and 5-HT7 receptors. We isolated a cDNA (Pr5-HT8) from larval Pieris rapae, which shares relatively low similarity to the known 5-HT receptor classes. After heterologous expression in HEK293 cells, Pr5-HT8 mediated increased [Ca2+](i) in response to low concentrations (<10nM) of 5-HT. The receptor did not affect [cAMP](i) even at high concentrations (>10M) of 5-HT. Dopamine, octopamine, and tyramine did not influence receptor signaling. Pr5-HT8 was also activated by various 5-HT receptor agonists including 5-methoxytryptamine, ()-8-Hydroxy-2-(dipropylamino) tetralin, and 5-carboxamidotryptamine. Methiothepin, a non-selective 5-HT receptor antagonist, activated Pr5-HT8. WAY 10635, a 5-HT1A antagonist, but not SB-269970, SB-216641, or RS-127445, inhibited 5-HT-induced [Ca2+](i) increases. We infer that Pr5-HT8 represents the first recognized member of a novel 5-HT receptor class with a unique pharmacological profile. We found orthologs of Pr5-HT8 in some insect pests and vectors such as beetles and mosquitoes, but not in the genomes of honeybee or parasitoid wasps. This is likely to be an invertebrate-specific receptor because there were no similar receptors in mammals.

TI Combined effects of phosphorus nutrition and elevated carbon dioxide concentration on chlorophyll fluorescence, photosynthesis, and nutrient efficiency of cotton SO JOURNAL OF PLANT NUTRITION AND SOIL SCIENCE LA English DT Article DE Gossypium hirsutum; nitrogen; photochemical quenching; photosystems ID ATMOSPHERIC CO2 CONCENTRATIONS; UNGUICULATA L. WALP.; WATER-USE EFFICIENCY; PHOSPHATE DEFICIENCY; PINUS-RADIATA; GROWTH; ENRICHMENT; RESPONSES; NITROGEN; YIELD AB To examine the combined effects of phosphorus (P) nutrition and CO2 on photosynthesis, chlorophyll fluorescence (CF), and nutrient utilization and uptake, two controlled-environment experiments were conducted using 0.01, 0.05 and 0.20 mM external phosphate each at ambient and elevated CO2 (aCO(2):400 and eCO(2) : 800 mu mol mol(-1), respectively). The CF parameters were affected more by P nutrition than by CO2 treatment. Photoinhibition of photosystem II (PSII) was due to increased minimal CF (Fo') and decreased maximal CF (Fm'), and efficiency of energy harvesting (Fv'/Fm'). In addition, reduced electron transport rate (ETR), the quantum yield of PSII (Phi(PSII)) and CO2 assimilation (Phi(CO2)), and overall photochemical quenching in the P-deficient leaves led to reduction in the efficiency of energy transfer to the PSII reaction center. Stimulation in the Phi(PSII)/Phi(CO2) and photorespiration (ETR/P-net) was found under P deficiency, whereas the opposite was the case under CO2 enrichment. On average, photosynthetic rate (P-net) and stomatal conductance declined by 50-53% at 0.05 mM P and by 70-72% at 0.01 mM P as compared to the 0.20 mM P treatment. However, P deficiency, especially at eCO(2), tended to increase the intrinsic water-use efficiency. In the P-deficient plants, the decline in the P and N-utilization efficiency (up to 91%) of biomass production was mainly associated with greater reduction in the biomass relative to the tissue P concentration as the P supply was reduced. However, it was significantly stimulated by eCO(2) especially at higher P supply. The CO2 x P interaction was observed for some parameters such as Fo', Fm', P utilization efficiencies of photosynthesis and biomass production that might be attributed to the irresponsiveness of these parameters to eCO(2) under low P treatment. Thus, P deficiency limited the beneficial effect of eCO(2). A close relationship between total biomass and photosynthesis with the P and N utilization or uptake efficiencies was found. The P utilization efficiency of P-net appeared to be stable across a range of leaf P concentrations, whereas the N-utilization efficiency markedly increased with leaf P and differed between CO2 levels. An apparent effect of both the treatments (P and CO2) on N-uptake and utilization efficiency also indicated the alteration in N acquisition and assimilation in cotton plants.

Objective To compare nutrient intake, diet quality, and weight/adiposity measures of consumers assigned to different breakfast patterns with breakfast skippers. Design and participants These associations were assessed in adults 19+ years (N=18,988) participating in the 2001-2008 National Health and Nutrition Examination Survey. Intake was determined from 1-day 24-hour dietary recall. Diet quality was quantified using the Healthy Eating Index-2005. Body mass index (calculated as kg/m(2)) and waist circumferences were determined. Twelve patterns (including No Breakfast [approximately 19% of population]), explaining 58% of the variance in energy from the breakfast meal, were examined. Covariate adjusted general linear models were used to compare nutrient intakes, Healthy Eating Index-2005 scores, and body mass index/waist circumference of consumers of different patterns with breakfast skippers. The P value was Bonferroni corrected (<0.05/12 breakfast patterns <0.0042). Results Consumers of the Grain/100% Fruit Juice and Presweetened Ready-to-Eat Cereal (RTEC)/Lower-Fat Milk patterns had lower daily intakes of nutrients to limit (added sugars, saturated fatty acids, solid fats, cholesterol, and sodium) than breakfast skippers. Consumers of the Grain/100% Fruit Juice; Presweetened RTEC/Lower-Fat Milk; and RTEC/Lower-Fat Milk/Whole Fruit/100% Fruit Juice patterns had higher daily intakes of all shortfall nutrients examined (dietary fiber; vitamins A, D, and C; calcium, potassium, folate, iron, and magnesium) than breakfast skippers. Consumers of the Grain/100% Fruit Juice; Grain; Presweetened RTEC/Lower-Fat Milk; RTEC/Lower-Fat Milk/Whole Fruit/100% Fruit Juice; Cooked Cereal; Lower-Fat Milk/Whole Fruit; and Whole Fruit patterns had higher Healthy Eating Index-2005 scores than breakfast skippers. Consumers of the Grain/100% Fruit Juice; Presweetened RTEC/Lower-Fat Milk; RTEC/Lower-Fat Milk/Whole Fruit/100% Fruit Juice; and Cooked Cereal patterns had lower body mass indexes and waist circumferences than breakfast skippers. Conclusions Results suggest dietary and weight advantages of consuming breakfast, especially ones that include grains, cereals, lower-fat milk, and whole fruit/100% fruit juice, in contrast to the potential adverse effects of skipping breakfast.

Generally, ungulate calving site selection varies by vulnerability to predators, local topography, habitat quality and level of human disturbance. The Mongolian saiga (Saiga tatarica mongolica) is endemic to Mongolia where a threatened population of approximate to 7000 exists in the northern Gobi Desert. We analyzed factors that could affect selection of saiga calving locations in the Sharga Nature Reserve, western Mongolia, using data obtained from ground surveys over 4 years between 2008 and 2012. Multiple factors explain calving location selection by saiga antelopes, based on the results of a generalized linear mixed model within a use availability framework. Individual saiga females preferred calving locations that were away from settlements and closer to water sources and avoided steeper slopes in comparison with random locations. These results demonstrate that the choice of calving locations for saiga antelope is driven by both internal and external factors. Understanding which factors influence calving location selection for saiga provides insights to protect important habitats. C1 [Buuveibaatar, B.; Fuller, T.

It is critical to identify useful sources of FHB resistance for durum wheat. A domesticated emmer wheat (T. turgidum subsp. dicoccum) accession, PI 41025, was previously shown to be moderately resistant to FHB. This study aimed to identify quantitative trait loci (QTL) associated with FHB resistance in PI 41025. A population of 200 recombinant inbred lines were developed from a cross between the durum cultivar 'Ben' and PI 41025 and evaluated for reactions to F. graminearum in one field nursery and three greenhouse experiments. The disease severity data and a single nucleotide polymorphism marker-based linkage map from this population were used for QTL analysis. The results showed that one QTL on chromosome 2A from Ben and one QTL each on 3A and 5A from PI 41025 were associated with FHB resistance. The 2A and 3A QTL each explaining 8 % of the phenotypic variation were detected only in the greenhouse experiments. The QTL on 5A, which mapped near the domestication gene Q, explained 11 and 35 % of phenotypic variation in greenhouse and field evaluations, respectively. The identification of the 2A QTL from Ben confirmed the presence of FHB resistance in North Dakota durum cultivars, which have been successfully used for developing new cultivars with improved FHB tolerance. This study indicates that combining the QTL from related tetraploid species with native durum QTL will be useful for improving FHB resistance in durum.

TI Identification of novel rice low phytic acid mutations via TILLING by sequencing SO MOLECULAR BREEDING LA English DT Article DE Phytic acid; Rice; TILLING by sequencing; Reverse genetics; lpa mutation ID ORYZA-SATIVA L.; GENOMIC DNA; MAIZE; GENE; SEEDS; DISCOVERY; MUTANT; PHOSPHORUS; GERMPLASM; REVEALS AB Phytic acid (myo-inositol-1,2,3,4,5,6-hexakisphosphate or InsP(6)) accounts for 75-85 % of the total phosphorus in seeds. Low phytic acid (lpa) mutants exhibit decreases in seed InsP(6) with corresponding increases in inorganic P which, unlike phytic acid P, is readily utilized by humans and monogastric animals. Since InsP(6) may also reduce the bioavailability of essential mineral cations, development of lpa seed crops for animal feeds and whole-grain consumers is of significant interest and requires better understanding of the metabolism of InsP(6) and the role it plays in other plant processes. To date, well over 20 lpa mutants have been reported in a number of species, most of which have been identified through forward genetic screens. In this study, we used a publicly available rice Targeting of Induced Local Lesions IN Genomes (TILLING) resource to identify four novel lpa mutations, two in one member of the inositol(1,3,4)P-3 5/6-kinase (ITPK) gene family (LOC_Os09g34300) and two in a multi-drug resistance-associated protein (MRP) gene (LOC_Os03g04920). The mutations in the ITPK gene resulted in significant reductions in InsP(6) (46 and 68 %), while those found in MRP gene were more modest (20 and 30 %). Evaluation of these lines indicates that one of the ITPK mutants (46 % InsP(6) reduction) and both MRP mutants are similar to wild-type plants in seed weight, germination, and seedling growth. The four mutants identified here represent new resources for the genetic dissection of phytic acid metabolism in rice and the development of germplasm and strategies for breeding lpa rice varieties.

In this study, microarray analysis was conducted to identify drought-responsive genes in the third topmost leaves of the field-grown drought-tolerant cotton (Gossypium hirsutum L.) cultivar Acala 1517-99 under drought stress conditions. Water stress was imposed by withholding irrigation for 9 days in the early squaring stage, which resulted in 10-15 % reduction in plant growth compared to the well-watered plants. A total of 110 drought-responsive genes (0.5 % of the total genes) were identified, 79 % (88 genes) of which were drought-repressed and 21 % (22 genes) were drought-induced. The drought-induced genes were grouped into six functional categories including stress-related (ten genes, nine of which encode heat shock proteins), metabolism (three genes) and one gene each for transcription factor, proline biosynthesis and cellular transport. The drought-repressed genes were classified into 14 functional categories, comprising metabolism (20 genes), cellular transport (12 genes), stress-related (12 genes), regulation of gene expression (nine genes), transcription factor (four genes), signal transduction (seven genes) and two genes each for biosynthesis of secondary compounds, cell wall, fatty acids/lipids and chlorophyll, and protein degradation. Most of the genes have been reported in other plants as drought-tolerant/responsive. The responsiveness of 19 selected drought-responsive genes was validated by quantitative RT-PCR. Furthermore, primers were developed and assayed for all the drought-responsive genes to develop single-strand conformation polymorphic markers, many of which were found to be correlated with drought tolerance. This report represents the first study on integration of a transcriptome analysis to develop molecular markers that are associated with drought tolerance in cotton.

Moench], affecting all aerial tissues of the plant. The most effective strategy for its control is the incorporation of resistance genes. The anthracnose resistance response present in the sorghum line SC112-14 (Cs-SC112) was therefore studied against pathotypes from Puerto Rico, Texas, Arkansas, and Georgia using F2 progenies and recombinant inbred lines. The results show that a series of nearest single loci at the distal region of chromosome 5 control the resistance responses against pathotypes from Puerto Rico, Texas, and Arkansas. Resistance loci against pathotypes from Texas and Puerto Rico are tightly linked and flanked by simple sequence repeat (SSR) markers Ch5-55.0 and Ch5-56.1, while the resistance locus against pathotypes from Arkansas is 9.5 cM below SSR marker Ch5-56.1. The resistance locus against pathotypes from Georgia is not located in the distal region of chromosome 5, and its location could not be determined. Comparative analysis confirmed that the region associated with these three loci is not associated with the anthracnose resistance locus Cg1, which was previously mapped in the distal region of the same chromosome. The dominant mode of action against pathotypes from Puerto Rico suggests that these resistances sources can be beneficial for sorghum hybrid production. The durability of anthracnose resistance in sorghum depends on the adequate use of multiple resistance sources. Thus, the knowledge and genetic markers developed herein provide tools to initiate the pyramiding of multiple anthracnose resistance loci through marker-assisted selection.

The map is comprised of 12 linkage groups (equivalent to the haploid chromosome number of diploid blueberry) and totals 1,740 cM. Included on the map are 265 markers based on simple sequence repeats, expressed sequence tag-polymerase chain reactions, single nucleotide polymorphisms, and randomly amplified polymorphic DNAs. The estimated map coverage is 89.9 %, and the average distance between markers is 7.2 cM. The mapping population was evaluated for 2 years (2009 and 2010) for mid-winter bud cold hardiness and for 3 years (2011-2013) for chilling requirement under controlled conditions. Broad-sense heritability of both cold hardiness and chilling requirement was quite high under these conditions with values of 0.88 and 0.86, respectively. One quantitative trait locus/loci (QTL) for cold hardiness and one for chilling requirement were identified that were consistent over at least 2 years. A second weaker QTL for chilling requirement was detected in only one of the 3 years.

Short sleep duration increases risk of obesity in Mexican American children SO SLEEP MEDICINE LA English DT Article DE Sleep; Obesity; Waist-to-height ratio; Mexican American children; Longitudinal; Accelerometer ID BODY-MASS INDEX; SEX-DIFFERENCES; BIRTH COHORT; ADOLESCENTS; OVERWEIGHT; CHILDHOOD; ASSOCIATION; ADIPOSITY; ACCELEROMETER; POPULATION AB Objective: Cross-sectional studies show that sleep is related to childhood obesity. We aimed to examine the longitudinal impact of sleep on the risk of obesity in Mexican American children. Design and methods: We evaluated 229 Mexican American 8-10-year-olds and their mothers at baseline and at 12- and 24-month follow-ups. Sleep duration and anthropometrics were collected. Age- and gender-specific body mass index (BMI) z-scores (BMIz) were calculated based on Centers for Disease Control and Prevention guidelines. Sleep duration was estimated using accelerometry. Children were also categorized as long or short sleepers, using the National Sleep Foundation's recommendation to define adequate sleep duration (10-11 h for 5-12-year-olds). Using linear regressions, we examined whether sleep duration predicted BMIz, waist-to-height ratio (WHtR), and weight gain at 24 months. Results: Children were mostly short sleepers (82%). Children who slept less were more likely to have a higher BMIz, WHtR, and weight gain at the 24-month follow-up (beta = -0.07, P = 0.01; beta = -0.11, P < 0.01; and beta = -0.14, P = 0.02, respectively), after controlling for baseline weight status, child gender, maternal BMI, and occupation. Conclusion: In Mexican American children, shorter sleep duration at baseline was associated with increased weight status over 24 months. (C) 2014 Elsevier B.V. All rights reserved.

TI Linking conservation actions to demography: grass height explains variation in greater sage-grouse nest survival SO WILDLIFE BIOLOGY LA English DT Article ID HABITAT SELECTION; NORTH-AMERICA; SUCCESS; VEGETATION AB Conservation success often hinges on our ability to link demography with implementable management actions to influence population growth (lambda). Nest success is demonstrated to be important to lambda in greater sage-grouse Centrocercus urophasianus, an imperiled species in the North American sagebrush-steppe. Enhancing this vital rate through management represents an opportunity to increase bird numbers inside population strongholds. We identified management for grass height as an action that can improve nest success in an analysis of sage-grouse nests (n = 529) from a long-term study (2003-2007) in the Powder River Basin, southeast Montana and northeast Wyoming, USA. Average grass height by study area and year varied (11.4-29.2 cm) but its positive effects on nest survival were consistent among study years and study areas that differed in absolute rates of nest success. We tested the predictive ability of models by grouping output from log-link analyses (2004-2006) into two bins with nest success probabilities < 0.45 and > 0.55, and validated the relationship with additional data from 2003 and 2007. Nests with probabilities > 0.55 were 1.64 (2004-2006) to 3.11 (2007) times more likely to hatch than those < 0.45, except in 2003 when an early wet spring resulted in universally high grass height at nest sites (29.2 cm) and high predicted nest success (64%). The high predictive power of grass height illustrates its utility as a management tool to increase nest success within priority landscapes. Relationships suggest that managing grass height during drought may benefit sage-grouse populations. C1 [Doherty, Kevin E.] US Fish & Wildlife Serv, Lakewood, CO 80228 USA.

TI Genetic analysis of a Bison bison herd derived from the Yellowstone National Park population SO WILDLIFE BIOLOGY LA English DT Article ID NORTH-AMERICAN BISON; BRUCELLA-ABORTUS; DOMESTIC CATTLE; PLAINS BISON; CONSERVATION; PROGRAM; RB51; MICROSATELLITES; INTROGRESSION; RELATEDNESS AB The objective of this study is to inventory the current genetic diversity of the bison quarantine feasibility study (BQFS) herd originating from Yellowstone National Park (YNP) using previously described microsatellite, mitochondrial and nuclear DNA markers with the aim to determine the degree, if any, of cattle DNA introgression in this herd. This work can provide an important tool in monitoring and managing bison genetic diversity as brucellosis-free reintroduced herds are re-established throughout the US for conservation purposes. The BQFS composed of 89 Bison bison from YNP that were quarantined and tested to qualify as free of brucellosis in 2006-2007. Understanding genetic diversity of the herd is important to determine if any genetic characteristics such as cattle DNA introgression or low genetic diversity may threaten the herd's protected status. We evaluated genetic diversity at 42 microsatellite loci representing each of the nuclear chromosomes in the bison genome. We found no detectable evidence of cattle DNA introgression in this herd through nuclear markers and mitochondrial DNA analysis. Parentage analysis of the BQFS herd indicated that the majority of mature adults were actively breeding and contributing off spring. Genetic diversity levels in the quarantined herd were high and comparable to the YNP parent herd, suggesting a low risk of genetic loss in the near future. Based on these findings, the genetic diversity currently available within the BQFS herd will provide a strong foundation for bison reintroduced herds and for the preservation of the species.

In this study, field measurements were integrated with a system model, Root Zone Water Quality Model (RZWQM2) to assess the sustainability and environmental impact of fertigation in an intensive olive grove (Olea europaea L. var. Arbeguina). The model provided acceptable predictions of evapotranspiration, soil moisture and nitrate contents. Based on model simulations, under current fertigation practices, 57% of the irrigation applied was lost via drainage, while 71% and 5% of fertilizer N inputs were lost through leaching and denitrification, respectively. The non-fertilizer N input from soil organic matter (OM) satisfied 64% of the crop N needs. The tested model was used to predict the impacts of a full irrigation (FIFC) and two regulated deficit irrigation schemes (RDI75, RDI50) on drainage and N leaching. In FIFC the atmospheric demand was met while the application frequency maintained the water storage below the soil field capacity. In RDI75 and RDI50 the irrigation application amount between stone hardening and onset of ripening was 75 and 50% of FIFC respectively. Compared with the current practice, the FIFC decreased drainage and N leaching by 47% and 90% respectively, while maintaining the actual evapotranspiration (ETa). The RDI75 seems to be the most adequate for the studied agro-system since, in relation to the FIFC, it saved 13% of irrigation water with only 5% decrease in ETa. Furthermore, the 15% reduction in leaching, together with the 19% increase in soil OM mineralization optimized the trees N uptake. The study of three different N application rates for each irrigation scenario indicated that, to minimize residual storage, N should be applied according to plant needs, by using a real-time indicator based upon foliar analysis or the chlorophyll meter measurements.

TI Use of Cordon Wire Tension for Static and Dynamic Prediction of Grapevine Yield SO AMERICAN JOURNAL OF ENOLOGY AND VITICULTURE LA English DT Article DE crop level; sensitivity; lag phase; sensor; remote estimation; automated system ID TRELLIS TENSION; CLIMATE; CROP AB An automated system was used during three growing seasons to monitor the change in tension (Delta T) in the load-bearing wire of a trellis to estimate yield in vineyards. Actual yield varied nearly four-fold among the three study years, but in each year the fruit was uniformly distributed along the length of the wire. The automated sensor detected sequential harvests up to similar to 12 m to either side of the sensor, or 24 m total wire length, in a nonlinear fashion. Yield was predicted statically from Delta T at the lag phase (L) of berry growth (Delta T-L) and dynamically from continuous output of Delta T. Relationships between Delta T-L and yield were linear. Estimated yield was not sensitive to the date of Delta T-L, within 10 days. In using the ratio between the current year Delta T and that of a specific previous year, the differences between estimated and observed yields depended upon the choice of predictor year(s), where years with similar Delta T were the most accurate. Across an estimation interval of L to harvest, the precision of dynamic estimates was determined by the similarity in the day-to-day shapes of the double-logistic curves of Delta T over time. Due to a catastrophic frost in the second year of the study, an extremely small crop and an uncharacteristic growth curve made it difficult to predict yield either statically or dynamically. In practice, the method requires a grower to collect multiple years of growth curves from which to build a robust linear relationship between Delta T-L and yield (static estimates), or to apply an average of multiple years' Delta T values dynamically.

TI Short Report: Antibody Prevalence of Select Arboviruses in Mute Swans (Cygnus olor) in the Great Lakes Region and Atlantic Coast of the United States SO AMERICAN JOURNAL OF TROPICAL MEDICINE AND HYGIENE LA English DT Article ID WEST-NILE-VIRUS; BIRDS AB Mute swans (Cygnus olor) are an invasive species in the United States. The dramatic increase in their populations in localized areas has led to various problems, among them competition with native species and attacks on humans by aggressive swans. However, very little is known about the ability of these swans to transmit pathogens to humans, domestic birds, or wildlife or participate in enzootic maintenance. To learn more about select pathogens that mute swans may harbor, a survey was conducted from April of 2011 to August of 2012 in the Great Lakes region and localized areas of the Atlantic coast, which revealed serologic evidence of arbovirus exposure in mute swans. Of 497 mute swans tested, antibodies were detected for eastern equine encephalitis (4.8%), St. Louis encephalitis (1.4%), West Nile (1.2%), and Turlock (0.6%) viruses. Samples were also tested for evidence of antibodies to La Crosse virus, but none were positive.

In a 2012 publication, Mitton and Ferrenberg suggested that climate change resulted in an unprecedented generation between June and September (a summer generation), with a concomitant shift to two generations in one year (bivoltinism). Although summer generations are not uncommon in this species, completion of a second generation across winter, between September and June, would be required for bivoltinism, a phenomenon not previously observed. Mitton and Ferrenberg showed that a summer generation can occur, but they failed to adequately track cohorts and provided no compelling evidence for bivoltinism. We demonstrate that a winter generationand hence bivoltinismwould have been physiologically impossible at the high-elevation site used in Mitton and Ferrenberg due to lower thermal developmental thresholds. The mountain pine beetle is indeed being influenced by climate change. To address the challenges of future population outbreaks of this significant tree mortality agent, however, it is imperative to consider evolved, thermally dependent traits that serve to maintain seasonality.

However, the populations of some species are declining and there is considerable urgency to develop ex situ conservation strategies. In this study, the storage physiology of seeds within Quercus was explored in order to determine factors that affect survival during cryopreservation and to provide a quantitative assessment of seed recalcitrance to support future studies of this complex trait. Methods Water relations and survival of excised axes in response to water loss and cryo-exposure were compared for four Quercus species from subtropical China (Q. franchetii, Q. schottkyana) and temperate USA(Q. gambelii, Q. rubra). Key Results Seed tissues initially had high water contents and water potentials. Desiccation tolerance of the embryonic axis was not correlated with the post-shedding rainfall patterns where the samples originated. Instead, higher desiccation tolerance was observed in samples growing in areas with colder winters. Survival following cryo-exposure correlated with desiccation tolerance. Among species, plumule tissues were more sensitive than radicles to excision, desiccation and cryo-exposure, and this led to a higher proportion of abnormally developing embryos during recovery following stress. Conclusions Quercus species adapted to arid and semi-humid climates still produce recalcitrant seeds. The ability to avoid freezing rather than drought may be a more important selection factor to increase desiccation tolerance. Cryopreservation of recalcitrant germplasm from temperate species is currently feasible, whilst additional protective treatments are needed for ex situ conservation of Quercus from tropical and subtropical areas.

Lin, Zhongxu TI Development of EST-based SNP and InDel markers and their utilization in tetraploid cotton genetic mapping SO BMC GENOMICS LA English DT Article DE Cotton; Molecular markers; SNP; InDel; Genetic mapping ID SINGLE-NUCLEOTIDE POLYMORPHISMS; GENOME; DISCOVERY; IDENTIFICATION; GOSSYPIUM; MAP; POPULATION; ANNOTATION; BLAST2GO; SSRS AB Background: Availability of molecular markers has proven to be an efficient tool in facilitating progress in plant breeding, which is particularly important in the case of less researched crops such as cotton. Considering the obvious advantages of single nucleotide polymorphisms (SNPs) and insertion-deletion polymorphisms (InDels), expressed sequence tags (ESTs) were analyzed in silico to identify SNPs and InDels in this study, aiming to develop more molecular markers in cotton. Results: A total of 1,349 EST-based SNP and InDel markers were developed by comparing ESTs between Gossypium hirsutum and G. barbadense, mining G. hirsutum unigenes, and analyzing 3' untranslated region (3' UTR) sequences. The marker polymorphisms were investigated using the two parents of the mapping population based on the single-strand conformation polymorphism (SSCP) analysis. Of all the markers, 137 (10.16%) were polymorphic, and revealed 142 loci. Linkage analysis using a BC1 population mapped 133 loci on the 26 chromosomes. Statistical analysis of base variations in SNPs showed that base transitions accounted for 55.78% of the total base variations and gene ontology indicated that cotton genes varied greatly in harboring SNPs ranging from 1.00 to 24.00 SNPs per gene. Sanger sequencing of three randomly selected SNP markers revealed discrepancy between the in silico predicted sequences and the actual sequencing results. Conclusions: In silico analysis is a double-edged blade to develop EST-SNP/InDel markers. On the one hand, the designed markers can be well used in tetraploid cotton genetic mapping. And it plays a certain role in revealing transition preference and SNP frequency of cotton genes. On the other hand, the developmental efficiency of markers and polymorphism of designed primers are comparatively low.

We recently showed that apo-10'-lycopenoic acid, a lycopene metabolite generated by beta-carotene-9',10'-oxygenase (BCO2), inhibited carcinogen-initiated, high-fat diet (HFD)-promoted liver inflammation, and hepatic tumorigenesis development. The present investigation examined the outstanding question of whether lycopene could suppress HFD-promoted hepatocellular carcinoma (HCC) progression, and if BCO2 expression is important using BCO2-knockout (BCO2-KO) and wild-type male mice. Results showed that lycopene supplementation (100 mg/kg diet) for 24 weeks resulted in comparable accumulation of hepatic lycopene (19.4 vs. 18.2 nmol/g) and had similar effects on suppressing HFD-promoted HCC incidence (19% vs. 20%) and multiplicity (58% vs. 62%) in wild-type and BCO2-KO mice, respectively. Intriguingly, lycopene chemopreventive effects in wild-type mice were associated with reduced hepatic proinflammatory signaling (phosphorylation of NK-kappa B p65 and STAT3; IL6 protein) and inflammatory foci. In contrast, the protective effects of lycopene in BCO2-KO but not in wild-type mice were associated with reduced hepatic endoplasmic reticulum stress-mediated unfolded protein response (ERUPR), through decreasing ERUPR-mediated protein kinase RNA-activated like kinase-eukaryotic initiation factor 2 alpha activation, and inositol requiring 1 alpha-X-box-binding protein 1 signaling. Lycopene supplementation in BCO2-KO mice suppressed oncogenic signals, including Met mRNA, beta-catenin protein, and mTOR complex 1 activation, which was associated with increased hepatic microRNA (miR)-199a/b and miR214 levels. These results provided novel experimental evidence that dietary lycopene can prevent HFD-promoted HCC incidence and multiplicity in mice, and may elicit different mechanisms depending on BCO2 expression.

We also measured the effect of parasitism on stem damage caused by the asparagus miner. The identity and abundance of the parasitoids of the asparagus miner were determined in asparagus fields in Michigan from weekly asparagus miner pupal collections during the 2010-2013 seasons. Twelve species of hymenopterous parasitoids were reared from asparagus miner pupae, including Chorebus rondanii (Giard) (Ichneumonoidea: Braconidae), 10 species in three families of Chalcidoidea, and one species of Bethylidae (Chrysidoidea), that represent new host records for the asparagus miner. C. rondanii and Thinodytes cephalon (Walker) (Pteromalidae) were the most common parasitoids. The effects of different diets and flowers on the lifespan of the pest and parasitoid adults were also evaluated. Buckwheat resulted in the shortest life span for the asparagus miner, whereas Riddell's goldenrod significantly increased its lifespan relative to the control. Parasitoid lifespan was doubled when individuals were fed sugar-rich diets. In the field, parasitoids preferred stems that contained more pupae and damage. The two most commonly reared parasitoids should be considered as targets for future conservation biological control efforts of the asparagus miner.

Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) is a parasitic wasp native to eastern Asia that has been introduced into the United States as part of a classical biological control program against the emerald ash borer Agrilus planipennis Fairmaire (Coleoptera: Buprestidae). We used computer-monitored flight mills to investigate the role of age, feeding status, mating status, and size on the flight capacity of female T. planipennisi over a 24-h period. We also compared flight capacity between sexes. Flight distance of female T. planipennisi representative of populations released in the biological control program averaged 1.26 km in 24 h with a maximum flight of just over 7 km. Median flight distance, however, was 422 m. The flight capacity of females fed a honey-water solution was 41 x that of females provided only water, who flew very little. Larger females were capable of flying farther distances, but age did not affect the flight capacity of females up to 70 d posteclosion. Females dispersed 6 x farther than did their smaller, male counterparts. The implications of our findings to host-parasitoid interactions and release protocols for distributing T. planipennisi are discussed.

In addition to codling moth, field trapping studies were conducted with oriental fruit moth, Grapholita molesta (Busck), obliquebanded leafroller Choristoneura rosaceana (Harris), the leafroller Pandemis pyrusana Kearfott, and the eyespotted budmoth, Spilonota ocellana (Denis and Schiffermuller). HPVs included ethyl (E,Z)-2,4-decadienoate (pear ester), (E)-4,8-dimethyl-1,3,7-nonatriene, butyl hexanoate, (E)-beta-ocimene, (E)-beta-farnesene, and farnesol. Three types of GAA co-lures differing in a 10-fold range in weekly evaporation rates were tested. The evaporation rate of GAA co-lures was an important factor affecting moth catches. The highest rate tested captured fewer codling moth but more leafrollers and eyespotted budmoth. GAA co-lures caught both sexes of each species. The field life of butyl hexanoate and (E)-beta-ocimene lures were much shorter than pear ester or sex pheromone lures. Adding GAA to pear ester or to (E)-beta-ocimene significantly increased the catches of only codling moth or oriental fruit moth, respectively. Combining pear ester or (E)-beta-ocimene with GAA did not affect the catch of either species compared with the single more attractive HPV. Adding HPVs to GAA did not increase the catches of either leafroller species or eyespotted budmoth. Traps baited with pear ester, sex pheromone, and GAA for monitoring codling moth were also effective in classifying pest pressure of both leafroller species within orchards. C1 [Knight, A.

A landscape management framework that incorporates all systems, across the spectrum of degrees of alteration, provides a fuller set of options for how and when to intervene, uses limited resources more effectively, and increases the chances of achieving management goals. That many ecosystems have departed so substantially from their historical trajectory that they defy conventional restoration is not in dispute. Acknowledging novel ecosystems need not constitute a threat to existing policy and management approaches. Rather, the development of an integrated approach to management interventions can provide options that are in tune with the current reality of rapid ecosystem change.

Previously, analyses of selected genes in the fumonisin biosynthetic gene (fum) cluster in black aspergilli from California grapes indicated that fumonisin-nonproducing isolates of Aspergillus welwitschiae lack six fum genes, but nonproducing isolates of Aspergillus niger do not. In the current study, analyses of black aspergilli from grapes from the Mediterranean Basin indicate that the genomic context of the fum cluster is the same in isolates of A. niger and A. welwitschiae regardless of fumonisin-production ability and that full-length clusters occur in producing isolates of both species and nonproducing isolates of A. niger. In contrast, the cluster has undergone an eight-gene deletion in fumonisin-nonproducing isolates of A. welwitschiae. Phylogenetic analyses suggest each species consists of a mixed population of fumonisin-producing and nonproducing individuals, and that existence of both production phenotypes may provide a selective advantage to these species. Differences in gene content of film cluster homologues and phylogenetic relationships of fum genes suggest that the mutation(s) responsible for the nonproduction phenotype differs, and therefore arose independently, in the two species. Partial film cluster homologues were also identified in genome sequences of four other black Aspergillus species. Gene content of these partial clusters and phylogenetic relationships of fum sequences indicate that non-random partial deletion of the cluster has occurred multiple times among the species. This in turn suggests that an intact cluster and fumonisin production were once more widespread among black aspergilli. (C) 2014 Elsevier Inc. All rights reserved.

TI Temporal dynamics and population genetic structure of Fusarium graminearum in the upper Midwestern United States SO FUNGAL GENETICS AND BIOLOGY LA English DT Article DE Fusarium graminearum; Population genetic structure; Trichothecene mycotoxins; NX-2 ID HEAD BLIGHT; GIBBERELLA-ZEAE; WHEAT; BARLEY; CULMORUM; IMPACTS AB Fusarium graminearum sensu stricto causes Fusarium head blight (FHB) in wheat and barley, and contaminates grains with several trichothecene mycotoxins, causing destructive yield losses and economic impact in the United States. Recently, a F. graminearum strain collected from Minnesota (MN) was determined to produce a novel trichothecene toxin, called NX-2. In order to determine the spatial and temporal dynamics of NX-2 producing strains in MN, North Dakota (ND) and South Dakota (SD), a total of 463 F. graminearum strains were collected from three sampling periods, 1999-2000, 2006-2007 and 2011-2013. A PCR-RFLP based diagnostic test was developed and validated for NX-2 producing strains based on polymorphisms in the Tril gene. Trichothecene biosynthesis gene (Tri gene)-based polymerase chain reaction (PCR) assays and ten PCR-restriction fragment length polymorphism (RFLP) markers were used to genotype all strains. NX-2 strains were detected in each sampling period but with a very low overall frequency (2.8%) and were mainly collected near the borders of MN, ND and SD. Strains with the 3ADON chemotype were relatively infrequent in 1999-2000 (4.5%) but increased to 29.4% in 2006-2007 and 17.2% in 2011-2013. The distribution of 3ADON producing strains also expanded from a few border counties between ND and MN in 1999-2000, southward toward the border between SD and MN in 2006-2007 and westward in 2011-2013. Genetic differentiation between 2006-2007 and 2011-2013 populations (3%) was much lower than that between 1999-2000 and 2006-2007 (22%) or 1999-2000 and 2011-2013 (20%) suggesting that most change to population genetic structure of F. graminearum occurred between 1999-2000 and 2006-2007. This change was associated with the emergence of a new population consisting largely of individuals with a 3ADON chemotype. A Bayesian clustering analysis suggested that NX-2 chemotype strains are part of a previously described Upper Midwestern population. However, these analyses also suggest that the NX-2 isolates could represent a distinct population, but that interpretations of population assignment are influenced by the small number of NX-2 strains available for analysis.

A meta-analysis SO JOURNAL OF APPLIED ECOLOGY LA English DT Review DE biodiversity; boreal forest; clearcut; disturbance; forestry; structural retention; temperate forest; variable retention ID GREEN-TREE RETENTION; PUBLICATION BIAS; USNEA-LONGISSIMA; DEAD-WOOD; HABITAT; THRESHOLDS; RESPONSES; HARVESTS; FILL; TRIM AB Industrial forestry typically leads to a simplified forest structure and altered species composition. Retention of trees at harvest was introduced about 25years ago to mitigate negative impacts on biodiversity, mainly from clearcutting, and is now widely practiced in boreal and temperate regions. Despite numerous studies on response of flora and fauna to retention, no comprehensive review has summarized its effects on biodiversity in comparison to clearcuts as well as un-harvested forests. Using a systematic review protocol, we completed a meta-analysis of 78 studies including 944 comparisons of biodiversity between retention cuts and either clearcuts or un-harvested forests, with the main objective of assessing whether retention forestry helps, at least in the short term, to moderate the negative effects of clearcutting on flora and fauna. Retention cuts supported higher richness and a greater abundance of forest species than clearcuts as well as higher richness and abundance of open-habitat species than un-harvested forests. For all species taken together (i.e. forest species, open-habitat species, generalist species and unclassified species), richness was higher in retention cuts than in clearcuts. Retention cuts had negative impacts on some species compared to un-harvested forest, indicating that certain forest-interior species may not survive in retention cuts. Similarly, retention cuts were less suitable for some open-habitat species compared with clearcuts. Positive effects of retention cuts on richness of forest species increased with proportion of retained trees and time since harvest, but there were not enough data to analyse possible threshold effects, that is, levels at which effects on biodiversity diminish. Spatial arrangement of the trees (aggregated vs. dispersed) had no effect on either forest species or open-habitat species, although limited data may have hindered our capacity to identify responses. Results for different comparisons were largely consistent among taxonomic groups for forest and open-habitat species, respectively.Synthesis and applications. Our meta-analysis provides support for wider use of retention forestry since it moderates negative harvesting impacts on biodiversity. Hence, it is a promising approach for integrating biodiversity conservation and production forestry, although identifying optimal solutions between these two goals may need further attention. Nevertheless, retention forestry will not substitute for conservation actions targeting certain highly specialized species associated with forest-interior or open-habitat conditions.

TI Controlling Attachment and Growth of Listeria monocytogenes in Polyvinyl Chloride Model Floor Drains Using a Peroxide Chemical, Chitosan-Arginine, or Heat SO JOURNAL OF FOOD PROTECTION LA English DT Article ID SALMONELLA-TYPHIMURIUM; ANTIBACTERIAL ACTION; STAINLESS-STEEL; BIOFILMS; INACTIVATION; SANITIZERS; RECOVERY; SURVIVAL; SURFACES; CHICKEN AB Listeria monocyto genes can colonize a poultry processing plant as a resident in floor drains. Limiting growth and attachment to drain surfaces may help lessen the potential for cross-contamination of product. The objective of this study was to compare a hydrogen peroxide-peroxyacetic acid based chemical to chitosan-arginine or heat to prevent attachment of or destroy existing L. monocyto genes on the inner surface of model floor drains. L. monocyto genes was introduced to result in about 10(9) planktonic and attached cells within untreated polyvinyl chloride model drain pipes. Treatments (0.13% peroxide-based sanitizer, 0.1% chitosan-arginine, or 15 s of hot water at 95 to 100 degrees C) were applied immediately after inoculation or after 24 h of incubation. Following treatment, all pipes were incubated for an additional 24 h; planktonic and attached cells were enumerated by plate count. All treatments significantly (P <0.05) lowered numbers of planktonic and attached cells recovered. Chitosan-arginine resulted in approximately a 6-log reduction in planktonic cells when applied prior to incubation and a 3-log reduction after the inoculum had a chance to grow. Both heat and peroxide significantly outperformed chitosan-arginine (8- to 9-log reduction) and were equally effective before and after incubation. Heat was the only treatment that eliminated planktonic L. monocyto genes. All treatments were less effective against attached cells. Chitosan-arginine provided about a 4.5-log decrease in attached cells when applied before incubation and no significant decrease when applied after growth. Like with planktonic cells, peroxide peroxyacetic acid and heat were equally effective before or after incubation, causing decreases ranging from 7 to 8.5 log for attached L. monocyto genes. Applied at the most efficacious time, any of these techniques may lessen the potential for L. monocyto genes to remain as a long-term resident in processing plant floor drains.

It has been previously used to hypothesize an origin from montane forest. We sampled 18 species covering three sections within the genus and sequenced five cpDNA spacers, atpB-rbcL, psbK-psbI, psbA-trnH, rbcL, and trnL-trnF. BEAST was used to reconstruct phylogenetic relationship and time divergences, and S-DIVA and Lagrange were used, based on distribution area and ecotype data, for reconstruction of ancestral areas and events. Our results appear compatible with designation of three taxonomic sections within the genus. The generic stem and crown ages were Eocene, approximately 47 Ma, and Oligocene 27 Ma, respectively. The origin of Atraphaxis is confirmed as montane, with an ancestral area consisting of the Junggar Basin and uplands of the Pamir-Tianshan-Alatau-Altai mountain chains, and ancestral ecotype of montane forest. Two remarkable paleogeographic events, shrinkage of the inland Paratethys Sea at the boundary of the late Oligocene and early Miocene, and the time intervals of cooling and drying of global climate from 24 (22) Ma onward likely facilitated early diversification of Atraphaxis, while rapid uplift of the Tianshan Mountains during the late Miocene may have promoted later diversification.

We have used a mouse model to identify the developmental window when the skeletal musculature is vulnerable to programming and to identify factors that limit the muscle's ability to respond when normal nutrition is restored. We established that the developmental age when nutritional rehabilitation occurs following an episode of poor nutrition, rather than the duration or severity of the nutrient restriction, is the critical factor that determines if muscle mass can be recuperated. The ability to recover depends on whether the muscles' translational capacity, i.e. ribosomal abundance, can increase sufficiently to raise protein synthesis rates sufficiently to accelerate protein deposition. We show that the ability to increase ribosomal abundance was associated with increased expression of the nucleolar transcription factor UBF (upstream binding factor), which regulates RNA polymerase 1 activity and rRNA transcription, the limiting factor for ribosomal production. AbstractNutritionally-induced growth faltering in the perinatal period has been associated with reduced adult skeletal muscle mass; however, the mechanisms responsible for this are unclear. To identify the factors that determine the recuperative capacity of muscle mass, we studied offspring of FVB mouse dams fed a protein-restricted diet during gestation (GLP) or pups suckled from postnatal day 1 (PN1) to PN11 (E-UN), or PN11 to PN22 (L-UN) on protein-restricted or control dams. All pups were refed under control conditions following the episode of undernutrition. Before refeeding, and 2, 7 and 21days later, muscle protein synthesis was measured in vivo. There were no long-term deficits in protein mass in GLP and E-UN offspring, but in L-UN offspring muscle protein mass remained significantly smaller even after 18months (P<0.001). E-UN differed from L-UN offspring by their capacity to upregulate postprandial muscle protein synthesis when refed (P<0.001), a difference that was attributable to a transient increase in ribosomal abundance, i.e. translational capacity, in E-UN offspring (P<0.05); translational efficiency was similar across dietary treatments. The postprandial phosphorylation of Akt and extracellular signal-regulated protein kinases were similar among treatments. However, activation of the ribosomal S6 kinase 1 via mTOR (P<0.02), and total upstream binding factor abundance were significantly greater in E-UN than L-UN offspring (P<0.02). The results indicate that the capacity of muscles to recover following perinatal undernutrition depends on developmental age as this establishes whether ribosome abundance can be enhanced sufficiently to promote the protein synthesis rates required to accelerate protein deposition for catch-up growth.

TI Saturated Fat Intake Modulates the Association between an Obesity Genetic Risk Score and Body Mass Index in Two US Populations SO JOURNAL OF THE ACADEMY OF NUTRITION AND DIETETICS LA English DT Article DE Body mass index; Genetic risk score; Saturated fat; Saturated fatty acids; Obesity ID LIPID-LOWERING DRUGS; DIETARY-FAT; FOOD-INTAKE; POLYMORPHISM; WEIGHT; VALIDATION; HUMANS; ACIDS; ATHEROSCLEROSIS; ACTIVATION AB Combining multiple genetic variants related to obesity into a genetic risk score (GRS) might improve identification of individuals at risk of developing obesity. Moreover, characterizing gene-diet interactions is a research challenge to establish dietary recommendations to individuals with higher predisposition to obesity. Our objective was to analyze the association between an obesity GRS and body mass index (BMI) in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) population, focusing on gene-diet interactions with total fat and saturated fatty acid (SFA) intake, and to replicate findings in the Multi-Ethnic Study of Atherosclerosis (MESA) population. Cross-sectional analyses included 783 white US participants from GOLDN and 2,035 from MESA. Dietary intakes were estimated with validated food frequency questionnaires. Height and weight were measured. A weighted GRS was calculated on the basis of 63 obesity-associated variants. Multiple linear regression models adjusted by potential confounders were used to examine geneediet interactions between dietary intake (total fat and SFA) and the obesity GRS in determining BMI. Significant interactions were found between total fat intake and the obesity GRS using these variables as continuous for BMI (P for interaction=0.010, 0.046, and 0.002 in GOLDN, MESA, and meta-analysis, respectively). These association terms were stronger when assessing interactions between SFA intake and GRS for BMI (P for interaction=0.005, 0.018, and <0.001 in GOLDN, MESA, and meta-analysis, respectively). SFA intake interacts with an obesity GRS in modulating BMI in two US populations. Although determining the causal direction requires further investigation, these findings suggest that potential dietary recommendations to reduce BMI effectively in populations with high obesity GRS would be to reduce total fat intake mainly by limiting SFAs.

Scientists and land managers at the Sequoia National Forest would like to understand the mechanisms and rates of streambank erosion to evaluate management issues and post-wildfire effects. This study uses bank erosion hazard index (BEHI) and near-bank stress (NBS) methods developed in Rosgen (2006 Watershed Assessment of River Stability and Sediment Supply [WARSSS]) for predicting streambank erosion in a geographic area that is dominated by colluvium and in which streambank erosion modeling has not been previously evaluated. BEHI evaluates bank susceptibility to erosion based on bank angle, bank and bankfull height, rooting depth and density, surface protection, and stratification of material within the banks. NBS assesses energy distribution against the bank measured as a ratio of bankfull near-bank maximum depth to mean bankfull depth. We compared BEHI classes and NBS to actual bank erosion measured from 2008 to 2012. This index predicted streambank erosion with clear separation among BEHI ratings with R-2 values of 0.76 for extreme, 0.37 for high/very high, 0.49 for moderate, and 0.70 for low BEHI. The relationships between measured erosion and BEHI extend the application of BEHI/NBS to a new region where they can inform management priorities, afforestation, stream/riparian restoration projects, and potentially burned area rehabilitation.

The models are applied to eight diverse basins in the western United States (U.S.) (Arizona, California, Colorado, Montana, and Washington) affected by wildfires and assessed by input parameters, calibration methods, model constraints, and performance. No one model is versatile enough for application to all study sites. Results show inconsistency between model predictions for events across the sites and less confidence with larger return periods (25- and 50-year events) and post-fire predictions. The RCS method performs well, but application is limited to southern California. The USGS linear regression model has wider regional application, but performance is less reliable at the large recurrence intervals and post-fire predictions are reliant on a subjective modifier. Of the three curve number-based models, Wildcat5 performs best overall without calibration, whereas the calibrated TR-55 and HEC-HMS models show significant improvement in pre-fire predictions. Results from our study provide information and guidance to ultimately improve model selection for post-fire prediction and encourage uniform parameter acquisition and calibration across the western U.S. C1 [Kinoshita, Alicia M.; Hogue, Terri S.] Colorado Sch Mines, Dept Civil & Environm Engn, Golden, CO 80401 USA.

The Precipitation Runoff Modeling System (PRMS) was used to compare streamflow simulations based on five static parameterizations of land cover with those based on dynamically varying parameters derived from four land cover scenes for the period 1953-2012. The PRMS simulations based on static land cover illustrated consistent differences in simulated streamflow across the island. It was determined that the scale of the analysis makes a difference: large regions with localized areas that have undergone dramatic land cover change may show negligible difference in total streamflow, but streamflow simulations using dynamic land cover parameters for a highly altered subwatershed clearly demonstrate the effects of changing land cover on simulated streamflow. Incorporating dynamic parameterization in these highly altered watersheds can reduce the predictive uncertainty in simulations of streamflow using PRMS. Hydrologic models that do not consider the projected changes in land cover may be inadequate for water resource management planning for future conditions.

Much of this uncertainty arises from our limited understanding of the extent to which root-microbe interactions induce SOC losses (through accelerated decomposition or 'priming'(2)) or indirectly promote SOC gains (via 'protection' through interactions with mineral particles(3,4)). We developed a new SOC model to examine priming and protection responses to rising atmospheric CO2. The model captured disparate SOC responses at two temperate free-air CO2 enrichment (FACE) experiments. We show that stabilization of 'new' carbon in protected SOC pools may equal or exceed microbial priming of 'old' SOC in ecosystems with readily decomposable litter and highly clay content (for example, Oak Ridge(5)). In contrast, carbon losses induced through priming dominate the net SOC response in ecosystems with more resistant litters and lower clay content (for example, Duke(6)). The SOC model was fully integrated into a global terrestrial carbon cycle model to run global simulations of elevated CO2 effects. Although protected carbon provides an important constraint on priming effects, priming nonetheless reduced SOC storage in the majority of terrestrial areas, partially counterbalancing SOC gains from enhanced ecosystem productivity.

TI Distribution, Morphometry, and Land Use of Delmarva Bays SO WETLANDS LA English DT Article DE Carolina Bay; Prior converted; Depressional Wetlands; LiDAR; Delmarva Bay; GIS; Land use ID CAROLINA BAYS; EASTERN SHORE; WETLANDS; MARYLAND; ORIGIN AB Delmarva Bays are depressional wetlands that are elliptical in shape with sandy rims, and occur mainly in the central portion of the Delmarva Peninsula within the Mid-Atlantic United States. Situated in a region with abundant agriculture, Delmarva Bays and other wetlands may enhance water quality by reducing nutrient and sediment levels in local waters. A significant portion have been drained and converted from forested wetlands to agriculture. Using LiDAR to locate Bays, we estimate that there are 17,000 Bays on the Delmarva Peninsula, which is an order of magnitude greater than earlier estimates. Using a stratified sampling scheme based on Bay density, morphometric parameters of 1494 Bays were measured from the LiDAR data and their land use was assessed using aerial photography. Eighty percent of the Bays range in size from 0.46 to 5.68 ha, have a relief ranging between 0.55 and 2.02 m, and have a major to minor axis ratio between 1.08 and 1.65. Forty-one percent of the Bays sampled have been converted to agriculture and another 29 % have been partially converted, while 29 % retain natural vegetative cover. Improved understanding of the geomorphology, abundance and land cover of Delmarva Bays should lead to better management and conservation efforts. C1 [Fenstermacher, D. E.; Rabenhorst, M.

TI Developing and Evaluating Rapid Field Methods to Estimate Peat Carbon SO WETLANDS LA English DT Article DE Peat; Coring; Carbon; Sampling; Soil ID PEATLANDS; CYCLE; SOIL AB Many international protocols (e.g., REDD+) are developing inventories of ecosystem carbon stocks and fluxes at country and regional scales, which can include peatlands. As the only nationally implemented field inventory and remeasurement of forest soils in the US, the USDA Forest Service Forest Inventory and Analysis Program (FIA) samples the top 20 cm of organic soils, but there is a large unsampled fraction of soil carbon stored in America's peatland forests. Improved methods could allow the FIA program to more comprehensively estimate soil carbon stocks and stock change in forested peatlands. We evaluated six rapid peat sampling methods in northern peatlands: 1) general probing of peat thickness, 2) general probing of peat thickness by general vegetation type, 3) partial profile coring #1, 0-20 cm, 4) partial profile coring #2, 25-75 cm, 5) partial profile coring #3, 50-100 cm, 6) intermittent profile coring and compared them to 7) measurements derived from whole profile sampling. We also tested our methods against an independent database of 85 peat cores collected from Manitoba, Canada. Overall, we found that the 0-20 cm partial profile core method was the least accurate method and should not be used (64-67 % accurate). The remaining rapid peat sampling methods all provided accuracies > 85 % compared to whole profile sampling. In conclusion, we found that there are several good options for rapidly sampling peat C stocks that if incorporated, could greatly increase our estimates of carbon stored in peat.

TI Origin and Effect of Alpha 2.2 Acetobacteraceae in Honey Bee Larvae and Description of Parasaccharibacter apium gen. nov., sp nov. SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID COLONY COLLAPSE DISORDER; LACTIC-ACID BACTERIUM; ROYAL JELLY PROTEIN; SYMBIONTS; SEQUENCES; MELLIFERA; GUT; IDENTIFICATION; BUMBLEBEES; LOSSES AB The honey bee hive environment contains a rich microbial community that differs according to niche. Acetobacteraceae Alpha 2.2 (Alpha 2.2) bacteria are present in the food stores, the forager crop, and larvae but at negligible levels in the nurse and forager midgut and hindgut. We first sought to determine the source of Alpha 2.2 in young larvae by assaying the diversity of microbes in nurse crops, hypopharyngeal glands (HGs), and royal jelly (RJ). Amplicon-based pyrosequencing showed that Alpha 2.2 bacteria occupy each of these environments along with a variety of other bacteria, including Lactobacillus kunkeei. RJ and the crop contained fewer bacteria than the HGs, suggesting that these tissues are rather selective environments. Phylogenetic analyses showed that honey bee-derived Alpha 2.2 bacteria are specific to bees that "nurse" the hive's developing brood with HG secretions and are distinct from the Saccharibacter-type bacteria found in bees that provision their young differently, such as with a pollen ball coated in crop-derived contents. Acetobacteraceae can form symbiotic relationships with insects, so we next tested whether Alpha 2.2 increased larval fitness. We cultured 44 Alpha 2.2 strains from young larvae that grouped into nine distinct clades. Three isolates from these nine clades flourished in royal jelly, and one isolate increased larval survival in vitro. We conclude that Alpha 2.2 bacteria are not gut bacteria but are prolific in the crop-HG-RJ-larva niche, passed to the developing brood through nurse worker feeding behavior.

TI A Highly Diastereoselective Oxidant Contributes to Ligninolysis by the White Rot Basidiomycete Ceriporiopsis subvermispora SO APPLIED AND ENVIRONMENTAL MICROBIOLOGY LA English DT Article ID PHANEROCHAETE-CHRYSOSPORIUM; LIPID-PEROXIDATION; NONPHENOLIC LIGNIN; OXIDATIVE-DEGRADATION; MANGANESE PEROXIDASE; VERATRYL ALCOHOL; MODEL COMPOUNDS; SPRUCE WOOD; PINUS-TAEDA; FUNGI AB The white rot basidiomycete Ceriporiopsis subvermispora delignifies wood selectively and has potential biotechnological applications. Its ability to remove lignin before the substrate porosity has increased enough to admit enzymes suggests that small diffusible oxidants contribute to delignification. A key question is whether these unidentified oxidants attack lignin via single-electron transfer (SET), in which case they are expected to cleave its propyl side chains between C-alpha and C-beta and to oxidize the threo-diastereomer of its predominating beta-O-4-linked structures more extensively than the corresponding erythro-diastereomer. We used two-dimensional solution-state nuclear magnetic resonance (NMR) techniques to look for changes in partially biodegraded lignin extracted from spruce wood after white rot caused by C. subvermispora. The results showed that (i) benzoic acid residues indicative of C-alpha-C-beta cleavage were the major identifiable truncated structures in lignin after decay and (ii) depletion of beta-O-4-linked units was markedly diastereoselective with a threo preference. The less selective delignifier Phanerochaete chrysosporium also exhibited this diastereoselectivity on spruce, and a P. chrysosporium lignin peroxidase operating in conjunction with the P. chrysosporium metabolite veratryl alcohol did likewise when cleaving synthetic lignin in vitro. However, C. subvermispora was significantly more diastereoselective than P. chrysosporium or lignin peroxidase-veratryl alcohol. Our results show that the ligninolytic oxidants of C. subvermispora are collectively more diastereoselective than currently known fungal ligninolytic oxidants and suggest that SET oxidation is one of the chemical mechanisms involved.

TI Predominant bacterial and fungal assemblages in agricultural soils during a record drought/heat wave and linkages to enzyme activities of biogeochemical cycling SO APPLIED SOIL ECOLOGY LA English DT Article DE Climate change; Pyrosequencing; Enzyme activities; Microbial diversity; Soil microbial community ID MICROBIAL COMMUNITY STRUCTURE; SP-NOV.; CROPPING SYSTEMS; ATACAMA DESERT; ALKALINE SOIL; DIVERSITY; ARTHROBACTER; TEMPERATURE; SEDIMENTS; WATER AB Identification of microbial assemblages predominant under natural extreme climatic events will aid in our understanding of the resilience and resistance of microbial communities to climate change. From November 2010 to August 2011, the Southern High Plains (SHP) of Texas, USA, received only 39.6 mm of precipitation (vs. the historical average of 373 mm) and experienced the three hottest months (June-August 2011) since record keeping began in 1911. The objective of this study was to characterize soil bacterial (16 S rRNA gene) and fungal (internal transcribed spacer 1-4, ITS1-ITS4) species distribution and diversity via pyrosequencing during the peak of the drought/heat wave in July 2011 and when the Drought Index and temperatures were lower in March 2012. Samples were collected from two different soil types (loam and sandy loam) under two different dryland cropping histories (monoculture vs. rotation). Fungal Diversity Indexes were significantly higher after the drought/heat wave while Bacterial Indexes were similar. Bacterial phyla distribution in July 2011 was characterized by lower relative abundance of Acidobacteriaand Verrucomicrobia, and greater relative abundance of Proteobacteria, Chloroflexi, Actinobacteria and Nitrospirae than March 2012 samples. Further grouping of pyrosequencing data revealed approximately equal relative proportions of Gram positive (G+) and Gram negative (G-) bacteria in July 2011, while G-bacteria predominated in March 2012. Fungal class Dothideomycetes was approximately two times greater in July 2011 than in March 2012, while the class Sordariomycetes and a group of unidentified OTUs from Ascomycota increased from July 2011 to March 2012. Microbial community composition was less influenced by management history than by the difference in climatic conditions between the sampling times. Correspondence analysis identified assemblages of fungal and bacterial taxa associated with greater enzyme activities (EAs) of C, N, or P cycling found during the drought/heat wave. Microbial assemblages associated with arylsulfatase activity (key to S cycling), which increased after the drought/heat wave, were identified (Streptomyces parvisporogenes, Terrimonas ferruginea and Syntrophobacter sp.) regardless of the soil and management history. The distinct microbial composition found in July 2011 may represent assemblages essential to maintaining ecosystem function during extreme drought and intense heat waves in semiarid agroecosystems.

TI Harvest Management of 'Tifton 85' Bermudagrass for Cellulosic Ethanol Production SO BIOENERGY RESEARCH LA English DT Article DE Dilute acid pretreatment; Simultaneous saccharification and fermentation (SSF); Biofuel; Nitrogen; Biomass ID LIGNOCELLULOSIC BIOMASS; COASTAL BERMUDAGRASS; PERENNIAL GRASSES; FERTILIZATION; PRETREATMENT; CONVERSION; POTASSIUM; NITROGEN AB Bermudagrass (Cynodon spp.) is a common perennial summer forage crop in the southeastern USA that could also be used for cellulosic ethanol. This study was conducted on two sites near Midville, GA to assess biomass yields, nutrient utilization, and cellulosic ethanol production from bermudagrass over 2 years (2010 and 2011). The crop was harvested either three times (June, midsummer, and fall), twice (midsummer and fall), or only once in the fall. The first harvest tended to yield the same amount of biomass regardless of season. In 2010, the three-cut system yielded the most biomass overall, while there was little difference in total yields between the three systems in 2011. The concentrations of N, P, and K in harvested biomass changed with age of the crop and harvest timing. Total N and K removal was greatest in the three-cut system, particularly in 2011. Biomass fiber properties were slightly affected by harvest timing, but these data did not show correlations with ethanol yield. Ethanol production was measured by subjecting biomass to dilute acid pretreatment and simultaneous saccharification and fermentation (SSF) at bench scale in the laboratory. Some variation in ethanol production was observed among treatments in 2011. Though harvest timing had minor effects on conversion of the biomass to ethanol, biomass yield is still the major factor that determines per hectare production of cellulosic ethanol from bermudagrass. Under the conditions in this study, a single harvest appears to be the most economical system for producing cellulosic ethanol from this crop. To maximize yield, two or three cuts should be possible, but much more N would be removed in the three-cut system, with little additional yield.

TI Modeling Differential Growth in Switchgrass Cultivars Across the Central and Southern Great Plains SO BIOENERGY RESEARCH LA English DT Article DE Ecotypes; Photoperiod; ALMANAC model; Panicum virgatum; Local adaptation ID PANICUM-VIRGATUM L; PHOTOPERIOD EXTENSION; FORAGE GRASSES; UNITED-STATES; POPULATIONS; CLIMATE; ADAPTATION; PRODUCTIVITY; TEMPERATURE; MANAGEMENT AB Switchgrass (Panicum virgatum L.) has been recognized as a potential biofuel crop, because it is adapted to a wide range of environmental and climatic conditions. Zones of adaptation for many switchgrass cultivars are well documented and attributed to local adaptation to the temperature and photoperiod at the location of origin. The objective of this study is to develop cultivar-specific growth parameters for the Agricultural Land Management and Numerical Assessment Criteria (ALMANAC) model based on location of origin and use these parameters to predict the biomass production of two lowland cultivars (Alamo and Kanlow) and two upland cultivars (Blackwell and Cave-in-Rock) in the central and southern Great Plains (TX, AR, LA, OK, KS, and MO). The plant parameters adjusted for each cultivar's origin include average growing season temperature (22-27 A degrees C), photoperiod at growth onset (11.46-13.12 h), maximum number of heat units (1,500-2,300), maximum leaf area index (6-12), and light extinction coefficient (0.33-0.50). The absolute difference between the average simulated and measured yields across all seven field locations for each cultivar is less than 0.5 Mg ha(-1). Performance of the cultivar-specific parameters varies by location, but the parameters do a reasonable job of estimating the average yield (less than 15 % difference) of each cultivar for a majority of field locations. In addition, regional simulations of the four cultivars each show realistic spatial variation in yield across the central and southern Great Plains. The parameters derived in this project for the ALMANAC model provide a tool for optimizing choice of switchgrass cultivar on different soils, in different climates, and with different management across large geographic regions.

Maize was grown continuously with adequate fertilization over years both with and without a winter rye cover crop, and the 31-species reconstructed prairie was grown with and without spring nitrogen fertilization. Both maize stover and prairie biomass were harvested in the fall. We compared amounts of cellulosic biomass produced and harvested, carbohydrate contents as measured by both dietary and detergent methods, and estimated cellulosic ethanol yields per hectare. From 2009-2013, the cropping system with the largest non-grain biomass yield was fertilized prairie, averaging 10.4 Mg ha(-1) year(-1) aboveground biomass with average harvest removals of 7.8 Mg ha(-1) year(-1). The unfertilized prairie produced 7.4 Mg ha(-1) year(-1) aboveground biomass, with average harvests of 5.3 Mg ha(-1) year(-1). Lowest cellulosic (non-grain) biomass harvests were obtained from continuous maize systems, averaging 3.5 Mg ha(-1) year(-1) when grown with, and 3.7 Mg ha(-1) year(-1) when grown without a winter rye cover crop, respectively. Unfertilized prairie biomass and maize stover had equivalent dietary-determined potential biomass ethanol yields at 330 g ethanol kg(-1) dry biomass, but fertilized prairie was lower at 315. The detergent method did not accurately capture these differences. Over the five-year period of the experiment, unfertilized and fertilized prairie systems averaged 810 and 1,790 L potential cellulosic ethanol ha(-1) year(-1) more than the maize systems, respectively. Differences in harvested biomass accounted for > 90 % of ethanol yield variation. C1 [Nichols, V. A.; Miguez, F. E.; Liebman, M. Z.] Iowa State Univ, Dept Agron, Ames, IA 50011 USA. [Jarchow, M.

Initial assessments of the impact of adopting bioenergy crops as a significant energy source have largely focused on the potential for bioenergy agroecosystems to provide global-scale climate regulating ecosystem services via biogeochemical processes. Such as those processes associated with carbon uptake, conversion, and storage that have the potential to reduce global greenhouse gas emissions (GHG). However, the expansion of bioenergy crops can also lead to direct biophysical impacts on climate through water regulating services. Perturbations of processes influencing terrestrial energy fluxes can result in impacts on climate and water across a spectrum of spatial and temporal scales. Here, we review the current state of knowledge about biophysical feedbacks between vegetation, water, and climate that would be affected by bioenergy-related land use change. The physical mechanisms involved in biophysical feedbacks are detailed, and interactions at leaf, field, regional, and global spatial scales are described. Locally, impacts on climate of biophysical changes associated with land use change for bioenergy crops can meet or exceed the biogeochemical changes in climate associated with rising GHG's, but these impacts have received far less attention. Realization of the importance of ecosystems in providing services that extend beyond biogeochemical GHG regulation and harvestable yields has led to significant debate regarding the viability of various feedstocks in many locations. The lack of data, and in some cases gaps in knowledge associated with biophysical and biochemical influences on land-atmosphere interactions, can lead to premature policy decisions.

Despite the historical recognition that amphibians could play an important role in the movement of biomass and nutrients, very few studies have provided reliable estimates of abundance and density of amphibians to reveal their true importance. Here, we provide robust estimates of abundance and density of a dominant species, the Southern Redback Salamander (Plethodon serratus Grobman, 1944), in the oak forest ecosystem of the Ozark Highlands in Missouri. We then use the abundance and density estimates to calculate biomass and nutrient content of salamanders at our study sites in the Ozark forests. Salamanders at the Sinkin Experimental Forest comprise a large amount of protein, energy, and nutrients that greatly exceed estimates derived some 35 years ago in the Hubbard Brook Experimental Forest, New Hampshire. Our estimates (7 300-12 900 salamanders.ha(-1)) are 2-4 times greater than the values reported by Burton and Likens (1975a, Ecology, 56: 1068-1080; 1975b, Copeia, 1975: 541-546). Furthermore, we show that density estimates of other small plethodontid species reported in the literature are nearly an order of magnitude greater than that reported by Burton and Likens. We believe this indicates that previous results have underestimated the importance of salamander biomass, nutrient, and energy flux, and their functional role in regulating invertebrates and carbon retention in forest ecosystems.

SO ENVIRONMENT INTERNATIONAL LA English DT Article DE Chernobyl accident; Forest fires; Redistribution; Radionuclides; Risks ID POWER-PLANT ACCIDENT; IONIZING-RADIATION; TRANSPORT; DEPOSITION; CS-137; RADIONUCLIDES; FALLOUT; EXPOSURE; MODEL; RATES AB Radioactive contamination in Ukraine, Belarus and Russia after the Chernobyl accident left large rural and forest areas to their own fate. Forest succession in conjunction with lack of forest management started gradually transforming the landscape. During the last 28 years dead wood and litter have dramatically accumulated in these areas, whereas climate change has increased temperature and favored drought. The present situation in these forests suggests an increased risk of wildfires, especially after the pronounced forest fires of 2010, which remobilized Chernobyl-deposited radioactive materials transporting them thousand kilometers far. For the aforementioned reasons, we study the consequences of different forest fires on the redistribution of Cs-137. Using the time frequency of the fires that occurred in the area during 2010, we study three scenarios assuming that 10%, 50% and 100% of the area are burnt. We aim to sensitize the scientific community and the European authorities for the foreseen risks from radioactivity redistribution over Europe. The global model LMDZORINCA that reads deposition density of radionuclides and burnt area from satellites was used, whereas risks for the human and animal population were calculated using the Linear No-Threshold (LNT) model and the computerized software ERICA Tool, respectively. Depending on the scenario, whereas between 20 and 240 humans may suffer from solid cancers, of which 10-170 may be fatal. ERICA predicts insignificant changes in animal populations from the fires, whereas the already extreme radioactivity background plays a major role in their living quality. The resulting releases of Cs-137 after hypothetical wildfires in Chernobyl's forests are classified as high in the International Nuclear Events Scale (INES). The estimated cancer incidents and fatalities are expected to be comparable to those predicted for Fukushima. This is attributed to the fact that the distribution of radioactive fallout after the wildfires occurred to the intensely populated Western Europe, whereas after Fukushima it occurred towards the Pacific Ocean. The situation will be exacerbated near the forests not only due to the expected redistribution of refractory radionuclides (also trapped there), but also due to the nutritional habits of the local human and animal population.

TI Hammondia hammondi Harbors Functional Orthologs of the Host-Modulating Effectors GRA15 and ROP16 but Is Distinguished from Toxoplasma gondii by a Unique Transcriptional Profile SO EUKARYOTIC CELL LA English DT Article ID GENE-EXPRESSION; TISSUE CYST; VIRULENCE; STRAINS; PROTEIN; CYCLE; CATS; DIFFERENTIATION; PSEUDOKINASES; BRADYZOITES AB Toxoplasma gondii and its nearest extant relative, Hammondia hammondi, are phenotypically distinct despite their remarkable similarity in gene content, synteny, and functionality. To begin to identify genetic differences that might drive distinct infection phenotypes of T. gondii and H. hammondi, in the present study we (i) determined whether two known host-interacting proteins, dense granule protein 15 (GRA15) and rhoptry protein 16 (ROP16), were functionally conserved in H. hammondi and (ii) performed the first comparative transcriptional analysis of H. hammondi and T. gondii sporulated oocysts. We found that GRA15 and ROP16 from H. hammondi (HhGRA15 and HhROP16) modulate the host NF-kappa B and STAT6 pathways, respectively, when expressed heterologously in T. gondii. We also found the transcriptomes of H. hammondi and T. gondii to be highly distinct. Consistent with the spontaneous conversion of H. hammondi tachyzoites into bradyzoites both in vitro and in vivo, H. hammondi high-abundance transcripts are enriched for genes that are of greater abundance in T. gondii bradyzoites. We also identified genes that are of high transcript abundance in H. hammondi but are poorly expressed in multiple T. gondii life stages, suggesting that these genes are uniquely expressed in H. hammondi. Taken together, these data confirm the functional conservation of known T. gondii virulence effectors in H. hammondi and point to transcriptional differences as a potential source of the phenotypic differences between these species.

The OE technique specifies appropriate error covariance matrices and optimizes a forward model (Tropospheric ultraviolet radiative transfer model, TUV), and thus provides a supplemental method for use across the network of the Department of Agriculture UV-B Monitoring and Research Program (USDA UVMRP) for the retrieval of aerosol properties and TOC with reasonable accuracy in the UV spectral range under various atmospheric conditions. In order to assess the accuracy of the OE technique, we compared the AOD retreivals from this method with those from Beer's Law and the AErosol RObotic Network (AERONET) AOD product. We also examine the OE retrieved TOC in comparison with the TOC from the U.S. Department of Agriculture UV-B Monitoring and Research Program (USDA UVMRP) and the Ozone Monitoring Instrument (OMI) satellite data. The scatterplots of the estimated AOD from the OE method agree well with those derived from Beer's law and the collocated AERONETAOD product, showing high values of correlation coefficients, generally 0.98 and 0.99, and large slopes, ranging from 0.95 to 1.0, as well as small offsets, less than 0.02 especially at 368 nm. The comparison of TOC retrievals also indicates the promising accuracy of the OE method in that the standard deviations of the difference between the OE derived TOC and other TOC products are about 5 to 6 Dobson Units (DU). Validation of the OE retrievals on these selected dates suggested that the OE technique has its merits and can serve as a supplemental tool in further analyzing UVMRP data.

TI Phenotypic characterization of the Miami World Collection of sugarcane (Saccharum spp.) and related grasses for selecting a representative core SO GENETIC RESOURCES AND CROP EVOLUTION LA English DT Article DE Bioenergy; Biofuel; Core collection; Diversity; Energy cane; Sugar cane yellow leaf virus ID GENETIC DIVERSITY; CROP IMPROVEMENT; POPULATION; RESOURCES; PATHOGENS; YIELD AB The Saccharum L. genus includes important crops that are utilized for sugar and fuel production. The World Collection of Sugarcane and Related Grasses (World Collection) in Miami, FL contains diverse and potentially useful germplasm for this and related genera; however, this collection has been underutilized because little is known about the traits of its accessions. Our objectives were to phenotypically characterize the World Collection and select a representative core collection that could then be studied intensively. In total, eight morphological traits of the World Collection were evaluated three times in 1 year. A core of 300 accessions that included each species in the World Collection was selected by using the Maximization Strategy in MStrat software. The core had a higher diversity rating than random selections of 300 accessions. The Shannon-Weaver Diversity Index scores of the core and whole collection were similar indicating that the majority of the diversity was captured by the core collection. The ranges and medians between the core and World Collection were similar; only two of the trait medians were not significant at P = 0.05 using the non-parametric Wilcoxon method and the coincidence rate (CR % = 96.2) was high (> 80) indicating that extreme values were retained. Thus, the phenotypic diversity of these traits in the World Collection was well represented by the core collection. Agronomic studies on the core should be useful for characterizing the World Collection and genes for useful traits should be available in the core collection.

WPCs were prepared with high-density polyethylene (HDPE) and treated WF was prepared by means of extrusion followed by injection molding, and the water absorption characteristics and mechanical properties of the products were evaluated. WPCs produced with extracted WF had lower water absorption rates and better mechanical properties than those made of untreated WF. WPCs containing delignified WF had higher water absorption rates and improved mechanical performance compared with those made of untreated WF.

In the present study, veneers from rotary cut birch (Betula pendula Roth) were produced from logs harvested in spring, autumn and winter, and soaked at 20 degrees C and 70 degrees C prior to peeling. Firstly, veneers produced from logs felled in autumn were dried at 103 degrees C for 24 h and subsequently half of these veneers were heat-treated at 180 degrees C for 3 h. In addition, veneers produced from logs felled in all three seasons were dried at 160 degrees C for 3.5 min to simulate industrial drying. The wettability of veneers was evaluated goniometrically, and bonding strength was evaluated with an automated bonding evaluation system (ABES). The results show that soaking birch logs at 70 degrees C rather than at 20 degrees C before peeling, or harvesting trees in the spring rather than in the autumn or winter, gives rise to veneers with enhanced wettability and higher bond strengths with a phenol-formaldehyde adhesive. Changes in the preparation and history of a veneer surface may have a profound effect on the development of adhesive bonds.

Furthermore, a separate hydrolysis fermentation (SHE) configuration was carried out to establish a baseline in sugar consumption and ethanol production from the ISP lines. The thermotolerant ethanol producing yeast strain Kluyveromyces marxianus NCYC 851 and the mesophilic Saccharomyces cerevisiae Ethanol Red were evaluated, using commercial alpha amylases for hydrolysis of available ISP starch to sugars. Fermentation by S. cerevisiae during SHF had an ethanol yield of 0.32 g/g dry ISP, a 1.1-fold increase above that produced by K. marxianus. Subsequent studies showed that ethanol yield could be increased in a SSF system with a maximum ethanol yield of 0.39 g/g dry ISP achieved, a 15% increase compared with using a SHF system when S. cerevisiae was used. Simultaneous extraction and fermentation of flour purple-fleshed NC-413 ISPs was studied to evaluate the effect of pH on extraction of total monomeric anthocyanins (TMA) and ethanol production. On average, maximum ethanol yield ranged from 0.31 to 0.34 g/g dry ISP and TMA concentration ranged from 45 to 64 mg cyanidin-3-glu/100 g dry powder (10-22 mg/100 g fresh weight) with the greatest ethanol production coming from non-adjusted pH fermentations. The highest anthocyanin recovery, 64 mg cyanidin-3-glu/100g dry powder was obtained at 35 degrees C and pH 4.5 using S. cerevisiae Ethanol Red. This study showed the feasibility of extracting anthocyanins and producing ethanol simultaneously in one unit operation without the need of purified solvents. (C) 2014 Elsevier B.V.

There has been a push to better understand root morphological and architectural traits and their plasticity because these traits determine the capacity of plants to effectively acquire available water and soil nutrients in the soil profile. In this study, two sets of germplasm materials were used to investigate the root system of the new oilseed crop Physaria fendleri (syn. Lesquerella fendleri) and gather preliminary information on available variability in root traits of the taxa and determine their response to temperature previously found optimal for above ground biomass development in the field. One experiment consisted of eighteen Physaria accessions grown in germination pouches for 21 days under two temperature treatments (21/13 degrees C and at 30/21 degrees C) then screened for nine root system parameters. Substantial variation in root length was found within the taxon. Apical root length was plastic in response to temperature with plants growing longer apical root zones when grown at a higher temperature and no difference in other root variables associated with temperature. The second experiment consisted of three accessions of P. fendleri and two of its sister genus Paysonia grown for 60 days in the greenhouse. Root trait analyses indicated that total root length, root length density, specific surface area and diameter differed between the two genera. Two accessions of P. fendleri, WCL-LO4 and PI 596456, were represented in both laboratory and greenhouse experiments. PI 596456 exhibited greater root:shoot ratio and root mass ratio than WCL-LO4 in both growth environments. This root trait screening in P. fendleri and Paysonia provided initial information in lesquerella as basis for future genetic and/or physiological studies relating to its root system.

Asian citrus psyllids Diaphorina citri (Kuwayama) (ACP) infestation was used to induce biotic stress while a water deficit was imposed to induce abiotic stress. Potted trees were infested by placing 50 psyllids on 3 citrus leaves enclosed in nylon mesh bags for 5 d. A parallel set of plants were kept water stressed by maintaining the soil at 20% water holding capacity for 5 d. Levels of total free amino acids were higher in water stressed and ACP infested leaves. Polyamine putrescine increased in infested leaves but not in water stressed leaves. Proline was the most abundant amino acid and its levels significantly increased by both biotic and abiotic stresses. Proline levels in infested leaves were significantly higher than the water stressed leaves. Histidine, methionine, asparagine, arginine, serine, and leucine levels also increased significantly in infested leaves, but in water stressed leaves only leucine, methionine, and threonine increased. Levels of amino acids, such as tyrosine, isoleucine, phenylalanine, glutamic acid, and alanine, declined in infested leaves. Under water stress asparagine, phenylalanine, serine, and histidine also declined compared to controls. This indicates that while proteolysis occurred under both stresses, metabolic conversion of amino acids was different under the two stresses. In ACP infested leaves some amino acids may be used as feeding material and/or converted into secondary metabolites for defense. C1 [Malik, Nasir S. A.] USDA ARS, ERRC, Wyndmoor, PA 19038 USA.

Hi-Glc-induced oxidative damage was demonstrated by a series of increase in superoxides (560%, 0.5 h), MDA (400%, 24 h), NF-kappa B activation (474%, 4 h) and a wild fluctuation of Delta Psi m relative to the control cells (p <= 0.05). MLP treatments ameliorate Hi-Glc-induced negative effects by a 40% reduction in ROS production, 34-44% reduction in MDA production, over 35% inhibition of NF-kappa B activation, as well as exert protective effect on HepG2 cells from change in Delta Psi m. Our data show that MLP in vitro can protect hepatoctyes from hyperglycemia-induced oxidative damages.

KUNKLE INTERDISCIPLINARY BEEF SYMPOSIUM: Overlapping physiological responses and endocrine biomarkers that are indicative of stress responsiveness and immune function in beef cattle SO JOURNAL OF ANIMAL SCIENCE LA English DT Article; Proceedings Paper CT Bill E K Interdisciplinary Beef Symposium - Beef cattle welfare and stress CY FEB 03, 2014 CL Dallas, TX DE cattle; stress; well-being ID ACUTE-PHASE RESPONSE; LIPOPOLYSACCHARIDE CHALLENGE; TRANSPORTATION; DEFENSE AB Acknowledgment that modern livestock production systems impose stress on animals has been accepted by the scientific community and producers. As the economic burden has increased for livestock producers, expectations for animal performance have increased, thus placing more strain on the entire production system. Whether or not periodic exposure to stress within the production system jeopardizes the well-being of animals continues to be an area of debate largely because of the inability to accurately quantify the magnitude and severity of the stress response on other biological systems. Adding to the confusion is the fact that activation of the stress axis can be both beneficial and detrimental to the body depending on the duration of the stress response and the frequency at which an animal is exposed to stressful stimuli. Few would argue that continuous long-term stress inhibits livestock productivity and overall wellbeing. Less clear is whether or not occasional exposure to acute stress jeopardizes the productivity and well-being of livestock. To fully appreciate the complexity associated with activation of the stress axis and the overall biological impact on the body, one must delve deep into the scientific literature and examine the science in an unbiased manner. It is imperative to appreciate and understand that activation of the stress axis is an essential survival mechanism necessary to maintain homeostasis during biologically challenging times. Acute activation of the stress axis leads to repartitioning of energy to organs and tissues essential for coping with stress, redirection of blood flow from the peripheral to large muscle groups, decreased digestive function, and priming of the immune system to prepare for subsequent infections. Conversely, chronic activation of the stress axis disrupts digestive function, causes catabolism of muscle and adipose tissue, and suppresses overall immune function, thus making an animal more susceptible to disease. But what parameters are needed to distinguish periods of acute stress from those of chronic stress, and what biological markers are the best indicators of "stress" in an animal? Although there are a plethora of physiological responses and endocrine biomarkers that can be quantified, an integrative tool that has been readily embraced by scientists and producers as an effective and efficient indicator of the duration and magnitude of stress that an animal is experiencing has yet to be identified.

TI CAPN1, CAST, and DGAT1 genetic effects on preweaning performance, carcass quality traits, and residual variance of tenderness in a beef cattle population selected for haplotype and allele equalization SO JOURNAL OF ANIMAL SCIENCE LA English DT Article; Proceedings Paper CT Bill E K Interdisciplinary Beef Symposium - Beef cattle welfare and stress CY FEB 03, 2014 CL Dallas, TX DE beef tenderness; CAPN1; carcass quality; CAST; DGAT1; marker association ID INFRARED REFLECTANCE SPECTROSCOPY; SINGLE-NUCLEOTIDE POLYMORPHISMS; LONGISSIMUS TENDERNESS; BOS-TAURUS; GENOTYPE PROBABILITIES; ONLINE CLASSIFICATION; EFFICIENT COMPUTATION; INTRAMUSCULAR FAT; MU-CALPAIN; ASSOCIATION AB Genetic marker effects and type of inheritance are estimated with poor precision when minor marker allele frequencies are low. A stable composite population (MARC III) was subjected to marker-assisted selection for multiple years to equalize specific marker frequencies to 1) estimate effect size and mode of inheritance for previously reported SNP on targeted beef carcass quality traits (n = 254), 2) estimate pleiotropic effects of previously reported SNP on nontarget performance traits (n = 542 or 254), and 3) evaluate tenderness SNP specific residual variance for LM tenderness. Three haplotypes within mu-calpain (CAPN1), a SNP in calpastatin (CAST), and a dinucleotide substitution in diacylglycerol O-acyltransferase 1 (DGAT1) were successfully selected to equalize their frequencies. Traits evaluated were birth BW, weaning BW, yearling BW, final BW, dressing percent, HCW, fat thickness, LM area, USDA marbling score, yield grade, LM slice shear force (SSF), and visible and near-infrared (VISNIR)-predicted SSF. While the CAPN1 genotype effect on SSF was not significant (P = 0.12), the direction and size of CAPN1 contrasts were consistent with previous research. Effects on SSF between divergent CAPN1 haplotypes (1.153 kg) and the additive effect of CAST (0.902 kg) were large, and animals homozygous for tender alleles at both CAPN1 and CAST would have 4.11 kg lower SSF (27.5% of the mean) than animals homozygous tough for both markers. Furthermore, the interaction between CAPN1 and CAST for SSF was not significant (P = 0.40). There were significant effects for DGAT1 on adjusted fat thickness (P = 0.02) and VISNIR-predicted SSF (P < 0.001) with additive and dominance modes of inheritance (P < 0.05) for both traits. Furthermore, CAST genotype specific residual variance models fit significantly better (P < 0.001) than single residual variance models for SSF, with the tougher genotypes having progressively larger residual (and hence phenotypic) variances. Therefore, risk of a tough steak from the undesired CAST genotype is increased through both an increase in mean and an increase in variation. This work is supportive of the importance of CAPN1 and CAST for mean tenderness in beef, confirms an effect of CAST on beef LM tenderness variation, and identifies an effect of DGAT1 on subcutaneous fat thickness.

TI The consequence of level of nutrition on heifer ovarian and mammary development SO JOURNAL OF ANIMAL SCIENCE LA English DT Article; Proceedings Paper CT Bill E K Interdisciplinary Beef Symposium - Beef cattle welfare and stress CY FEB 03, 2014 CL Dallas, TX DE developmental programming; heifer; mammary ovary ID DIRECTED COMPENSATORY GROWTH; ANTRAL FOLLICLE COUNT; REPRODUCTIVE-PERFORMANCE; PRIMORDIAL FOLLICLES; HOLSTEIN HEIFERS; MILK-PRODUCTION; LACTATION; PUBERTY; COWS; OBESITY AB Replacing cows in the herd is second only to nutrition as the single greatest input cost in cow/calf beef production. The increased availability of cereal grains for feeding livestock has allowed replacement heifers to enter the production system at younger ages. Many heifer development programs feed to ensure heifers reach puberty before the time that they are mated to calve at 2 yr of age. Nutrition level during development has been associated with altered milk production and stayability. We hypothesized that heifers exposed to a lower nutrition level during the peripubertal period would have less methylation of the DNA in the mammary gland and ovarian cortex. We also hypothesized that the ovarian reserve would decrease in heifers fed for rapid growth compared to heifers fed for slow growth during puberty. At 257 +/- 1 d of age, heifers in the Stair-Step treatment (n = 6) received 157 kcal ME/BW kg(0.75) for 84 d and heifers in the Conventional treatment (n = 6) were offered 228 kcal ME/BW kg(0.75). At d 84, heifers were fed for an additional 83 d. Stair-Step heifers were offered 277 kcal ME/BW kg(0.75), and heifers on the Conventional treatment received 228 kcal ME/BW kg(0.75). Mammary weights (P = 0.43), capillary area density (P = 0.74), and capillary surface density (P = 0.18) did not differ between treatments and neither did alveolar number (P = 0.55) and alveolar density (P = 0.49). Reproductive tract weights (P = 0.69) and ovarian weight (P = 0.68) and ovarian size (P > 0.75) did not differ between treatments. In histological sections, Stair-Step heifers had more primordial follicles than Conventional heifers (P = 0.02), but primary (P = 0.59) and secondary (P = 0.15) follicles did not differ. Global methylation of parenchymal tissue (P = 0.82), mammary fat pad (P = 0.45), and ovarian cortex (P = 0.14) did not differ between treatments. Anterior pituitary weight did not differ between treatments (P = 0.16). Our hypothesis that modifying peripubertal nutrition modifies global methylation of the mammary and ovary is not supported; however, our hypothesis that it modifies the ovarian reserve is supported.

Circulating ghrelin concentrations could potentially be used as a predictor of DMI in cattle. The objective of this experiment was to determine the association of circulating ghrelin concentrations with DMI and other production traits. Steers and heifers were fed a finishing diet, and individual intake was recorded for 84 d. Blood samples were collected via jugular venipuncture following the DMI and ADG measurement period. Plasma active ghrelin and total ghrelin were quantified using commercial RIA. Active ghrelin was not correlated to DMI (P = 0.36), but when DMI was modeled using a multivariate analysis including plasma metabolites and sex, active ghrelin was shown to be positively associated with DMI (P < 0.01) and accounted for 6.2% of the variation accounted for by the regression model (R-2 = 0.33). Total ghrelin was negatively correlated to DMI (P < 0.01), but was not significant in a multivariate regression analysis (P = 0.13). The ratio of active: total ghrelin was positively associated with DMI (P < 0.01) and accounted for 10.2% of the variation in the model (R-2 = 0.35). Active ghrelin was positively associated with ADG (P < 0.05), while total ghrelin was negatively associated with ADG (P < 0.01), and the ratio of active: total ghrelin was positively associated with ADG (P < 0.01). Active ghrelin was not associated with G: F (P = 0.88), but total ghrelin concentrations were negatively associated with G: F (P < 0.01) and accounted for 10.24% of the variation (R-2 = 0.25). Heifers consumed less feed than steers (P < 0.01), tended to have greater active ghrelin concentrations (P = 0.06), and had greater total ghrelin concentrations than steers (P = 0.04). Total ghrelin concentrations were not different between sire breeds (P = 0.80), but active ghrelin concentrations and the ratio of active: total ghrelin differed between breeds (P < 0.01), indicating that genetics have an effect on the amount and form of circulating ghrelin. Total ghrelin concentrations tended (P = 0.08) to be correlated with HCW, but no other carcass characteristics were correlated with active or total ghrelin concentrations (P > 0.10). Results indicated that ghrelin concentrations are associated with DMI in beef cattle and that there is genetic variation that leads to differences in the amount and form of circulating ghrelin which could contribute to variation observed in DMI of beef cattle.

Transgenic adenocarcinoma of the mouse prostate (TRAMP) prostate tumor responses to a 100 g of fat/kg diet (whole walnuts, walnut oil, and other oils; balanced for macronutrients, tocopherols [alpha-and gamma]) for 18 weeks ad libitum were assessed. TRAMP mice (n=17 per group) were fed diets with 100 g fat from either whole walnuts (diet group WW), walnut-like fat (diet group WLF, oils blended to match walnut's fatty acid profile), or as walnut oil (diet group WO, pressed from the same walnuts as WW). Fasted plasma glucose was from tail vein blood, blood was obtained by cardiac puncture, and plasma stored frozen until analysis. Prostate (genitourinary intact [GUI]) was weighed and stored frozen at -80 degrees C. Plasma triglyceride, lipoprotein cholesterol, plasma multianalyte levels (Myriad RBM Rat Metabolic MAP), prostate (GUI), tissue metabolites (Metabolon, Inc., Durham, NC, USA), and mRNA (by Illumina NGS) were determined. The prostate tumor size, plasma insulin-like growth factor-1 (IGF-1), high density lipoprotein, and total cholesterol all decreased significantly (P<.05) in both WW and WO compared to WLF. Both WW and WO versus WLF showed increased insulin sensitivity (Homeostasis Model Assessment [HOMA]), and tissue metabolomics found reduced glucose-6-phosphate, succinylcarnitine, and 4-hydroxybutyrate in these groups suggesting effects on cellular energy status. Tissue mRNA levels also showed changes suggestive of altered glucose metabolism with WW and WO diet groups having increased PCK1 and CIDEC mRNA expression, known for their roles in gluconeogenesis and increased insulin sensitivity, respectively. WW and WO group tissues also had increased MSMB mRNa a tumor suppressor and decreased COX-2 mRNA, both reported to inhibit prostate tumor growth. Walnuts reduced prostate tumor growth by affecting energy metabolism along with decreased plasma IGF-1 and cholesterol. These effects are not due to the walnut's N-3 fatty acids, but due to component(s) found in the walnut's fat component. C1 [Kim, Hyunsook] Konkuk Univ, Dept Physiol, Coll Vet Med, Seoul, South Korea.

Methods: The Study of Mental and Resistance Training was a randomized, double-blind, double-sham controlled trial of adults with MCI. Participants were randomized to 2 supervised interventions: active or sham physical training (high intensity progressive resistance training vs seated calisthenics) plus active or sham cognitive training (computerized, multidomain cognitive training vs watching videos/quizzes), 2-3 days/week for 6 months with 18-month follow-up. Primary outcomes were global cognitive function (Alzheimer's Disease Assessment Scale-cognitive subscale; ADAS-Cog) and functional independence (Bayer Activities of Daily Living). Secondary outcomes included executive function, memory, and speed/attention tests, and cognitive domain scores. Results: One hundred adults with MCI [70.1 (6.7) years; 68% women] were enrolled and analyzed. Resistance training significantly improved the primary outcome ADAS-Cog; [relative effect size (95% confidence interval) -0.33 (-0.73, 0.06); P <.05] at 6 months and executive function (Wechsler Adult Intelligence Scale Matrices; P = .016) across 18 months. Normal ADAS-Cog scores occurred in 48% (24/ 49) after resistance training vs 27% (14/ 51) without resistance training [P <.03; odds ratio (95% confidence interval) 3.50 (1.18, 10.48)]. Cognitive training only attenuated decline in Memory Domain at 6 months (P < . 02). Resistance training 18-month benefit was 74% higher (P = .02) for Executive Domain compared with combined training [z-score change -0.42 (0.22, 0.63) resistance training vs 0.11 (-0.60, 0.28) combined] and 48% higher (P <.04) for Global Domain [z-score change -.0.45 (0.29, 0.61) resistance training vs 0.23 (0.10, 0.36) combined]. Conclusions: Resistance training significantly improved global cognitive function, with maintenance of executive and global benefits over 18 months.

TI Comparative Assay of Antioxidant Packages for Dimer of Estolide Esters SO JOURNAL OF THE AMERICAN OIL CHEMISTS SOCIETY LA English DT Article DE Biodegradable oils; Esters; Estolides; Oxidation; PDSC; Stability ID DIFFERENTIAL SCANNING CALORIMETRY; METHYL SOYATE BIODIESEL; PHYSICAL-PROPERTIES; OXIDATIVE STABILITY; BIODEGRADABLE LUBRICANTS; 2-ETHYLHEXYL ESTERS; VEGETABLE-OILS; CASTOR; LESQUERELLA; ACIDS AB A series of 26 different antioxidants and commercial antioxidant packages designed for petroleum-based materials, containing both natural and synthetic-based materials, were evaluated with dimeric coconut-oleic estolide 2-ethylhexyl ester (2-EH), a bio-based material. The different antioxidants were categorized into different classes of phenolic, aminic, and blended/others materials. The oxidation onset temperatures (OT) using non-isothermal pressurized differential scanning calorimetry (PDSC) were measured and recorded under previously reported standard conditions. The aminic series gave the best resistance to oxidation as defined by the PDSC method with OT of 246.6 and 244.7 A degrees C for the best two performers, which was a 38 A degrees C improvement over the uninhibited or unformulated dimer estolide material. The phenolic series, containing most of the naturally occurring antioxidants, was the least successful formulation package for the dimer estolide. The blended/other materials, which were specifically designed for petroleum-based lubricants, did not have the best OT, since the estolides and other bio-based materials interact differently than their petroleum counterparts. A number of potential antioxidants have been identified as useful additives for the estolides esters. The OT of the estolide and formulated materials correlated well with other bio-based materials such as biodiesel.

It is a triglyceride containing 70-80 % vernolic acid (12,13-epoxy-9-decenoic acid). With approximately three epoxy groups per molecule, vernonia oil is a good raw material for new product development and many derivatives have been reported. In this work we report for the first time direct polymerization of vernonia oil through cationic means. The reaction entails the use of fluorosulfonic acid as a catalyst and 25-35 A degrees C. Depending on the level of acid catalyst used, the products can range from a viscous oil to a completely insoluble resin. These products have been characterized by NMR and FT-IR. The polymer may perhaps find applications as a thickener in lubricants and oil-based commercial formulations.

Products, not reported in prior studies of similar reactions, were found. These were furan fatty acid alkyl esters (FFE, mixture of alkyl 8-(5-hexyl-2-furyl) octanoate and alkyl 9-(5-pentyl-2-furyl)nonanoate) which were unambiguously identified by means of GC-MS and two-dimensional NMR. Evidence suggests that the FFE are formed by an acid-catalyzed rearrangement of the epoxidized linoleates. The FFE were formed in presence of all four alcohols tested and in the presence of either sulfuric acid or Amberlyst 15 catalyst. Yields of up to 13 %, as quantified by GC and NMR spectroscopies, were observed.

(Diptera: Muscidae) hosts at different host densities. Muscidifurax raptor had a significant impact on M. raptorellus when hosts were limiting in sequential parasitism tests. Fewer than six M. raptorellus adult progeny emerged from groups of 50 fly pupae that were parasitized by M. raptor at the same time or when M. raptor parasitism preceded M. raptorellus by 48 h, respectively, compared with 42-55 M. raptorellus progeny produced when this species was tested alone. Production of M. raptor was significantly lower when parasitism by this species was preceded by M. raptorellus (25) than when M. raptor was tested alone (43). When the two species parasitized hosts at the same time in different proportions at low host:parasitoid densities (5:1), M. raptorellus produced 13 progeny per parent female when it was the sole species present and fewer than two when M. raptor was present. No negative impact of M. raptorellus on M. raptor was observed. Neither species had a substantial effect on the success of the other at higher host:parasitoid densities. C1 [Geden, C. J.; Johnson, D.

In this study, we examined Aedes aegypti swarming behavior and identified associated chemical cues. Novel evidence is provided that Ae. aegypti females aggregate by means of olfactory cues, such as aggregation pheromones. Isolation of Ae. aegypti aggregation pheromones was achieved by aeration of confined mosquitoes and collection of associated volatiles by glass filters. The collected volatiles were identified through gas chromatography mass spectrometry (GCMS). Three aggregation pheromones were collected and identified as 2,6,6-trimethylcyclohex-2-ene-1,4-dione (ketoisophorone) (CAS# 1125-21-9, t(R) = 18.75), 2,2,6-trimethylcyclohexane-1,4-dione (the saturated analog of ketoisophorone) (CAS# 20547-99-3, t(R) = 20.05), and 1-(4-ethylphenyl) ethanone (CAS# 937-30-4, t(R) = 24.22). Our biological studies revealed that the identified compounds stimulated mosquito behavior under laboratory conditions. The mechanism of mosquito swarm formation is discussed in light of our behavioral study findings. A preliminary field trial demonstrated the potential application of the isolated aggregation pheromones in controlling Ae. aegypti.

Genotyping showed 111 failed and 229 succeeded. The failed types included "no peaks" (NP, 69 primers), "weak peaks" (WP, 30), and "multiple peaks" (MP, 12). The successful types were divided into HM (homozygous between two selected parents, 78 primers) and HT (heterozygous at least in one parent, 151 primers). The BLAST revealed primer alignment status, genomic amplicon size (GAS), and genomic and expressed amplicon size difference (ASD). The alignment status was categorized as: "no hits found" (NHF); "multiple partial alignments" (MPA); "single partial alignment" (SPA); "multiple full alignments" (MFA); and "single full alignment" (SFA). NHF and partial alignment (PA) mainly resulted from discrepant nucleotides in contig-derived primers. The ASD separated 247 non-NHF primers into: "deletion", "same size", "insertion", "intron (GAS a parts per thousand currency sign500)", "intron (GAS > 500)", and "error" categories. Most SFA primers were successful. About 88 % "error", 53 % NHF primers, and 47 % "intron (GAS > 500)" failed. The "deletion" and "insertion" primers had the higher HT rates, and the "same size" had the highest HM rate. Optimized primer selection criteria are discussed.

One hundred and fifty-nine genomic regions were identified on a saturated genetic map of more than 2,500 SSR and SNP markers, constructed with an interspecific recombinant inbred line (RIL) population derived from the genetic standards of the respective cotton species (G. hirsutum acc. TM-1 x G. barbadense acc. 3-79). Using the single nonparametric and MQM QTL model mapping procedures, we detected 428 putative loci in the 159 genomic regions that confer 24 cotton traits in three diverse production environments [College Station F&B Road (FB), TX; Brazos Bottom (BB), TX; and Shafter (SH), CA]. These putative QTL loci included 25 loci for PA, 60 for YC, and 343 for FP, of which 3, 12, and 60, respectively, were strongly associated with the traits (LOD score a parts per thousand yen 3.0). Approximately 17.7 % of the PA putative QTL, 32.9 % of the YC QTL, and 48.3 % of the FP QTL had trait associations under multiple environments. The At subgenome (chromosomes 1-13) contributed 72.7 % of loci for PA, 46.2 % for YC, and 50.4 % for FP while the Dt subgenome (chromosomes 14-26) contributed 27.3 % of loci for PA, 53.8 % for YC, and 49.6 % for FP. The data obtained from this study augment prior evidence of QTL clusters or gene islands for specific traits or biological functions existing in several non-homoeologous cotton chromosomes. DNA markers identified in the 159 genomic regions will facilitate further dissection of genetic factors underlying these important traits and marker-assisted selection in cotton.

Xie, Jiahua TI Differential expression of a novel gene EaF82a in green and yellow sectors of variegated Epipremnum aureum leaves is related to uneven distribution of auxin SO PHYSIOLOGIA PLANTARUM LA English DT Article ID LEAF VARIEGATION; CHLOROPLAST BIOGENESIS; ARABIDOPSIS-THALIANA; CORRELATIVE DOMINANCE; INDOLEACETIC-ACID; LIGHT INTENSITIES; PETIOLE EXPLANTS; AXILLARY BUDS; TRANSPORT; PLANTS AB EaF82, a gene identified in previous studies of the variegated plant Epipremnum aureum, exhibited a unique expression pattern with greater transcript abundance in yellow sectors than green sectors of variegated leaves, but lower abundance in regenerated pale yellow plants than in green plants derived from leaf tissue culture. Studies of its full-length cDNA and promoter region revealed two members with only the EaF82a expressed. Immunoblotting confirmed that EaF82a encodes a 12 kDa protein and its accumulation consistent with its gene expression patterns in different color tissues. Transient expression of EaF82a-sGFP fusion proteins in protoplasts showed that EaF82a seems to be present in the cytosol as unidentified spots. Sequence motif search reveals a potential auxin responsive element in promoter region. Using transgenic Arabidopsis seedlings carrying EaF82a promoter driving the bacterial uidA (GUS) gene, an increased GUS activity was observed when IAA (indole-3-acetic acid) concentration was elevated. In E. aureum, EaF82a is more abundant at the site where axillary buds emerge and at the lower side of bending nodes where more IAA accumulates relative to the upper side. The measurement of endogenous IAA levels in different color tissues revealed the same pattern of IAA distribution as that of EaF82a expression, further supporting that EaF82a is an IAA responsive gene. EaF82a expression in etiolated transgenic Arabidopsis seedlings responded to IAA under the influence of light suggesting a microenvironment of uneven light condition affects the EaF82a transcript levels and protein accumulation in variegated leaves.

The objective of this study was to characterize two novel alloplasmic CMSs, designated CMS GRO1 and CMS MAX3, with defective anthers, narrow disc florets with no swollen corolla, and short, narrow ray flowers derived from two tetraploid amphiploids (AMPs). Among 26 tested lines, only AMP Helianthus cusickii/P 21 and HA 410 failed to restore male-fertility. Segregation of CMS, male-fertile plants and plants with reduced male-fertility was observed both in the testcross progeny of a six line half-diallel cross of F(1)s with CMS MAX3 and in an F-2 population of CMS GRO1xRHA 274. Male-fertility restoration was controlled by at least two dominant genes. Detailed analysis of the mitochondrial genes may provide insight into the differences between these CMSs and other CMS lines. The new CMSs will facilitate the studies of the incompatibility between cytoplasmic and nuclear genes, especially for the alloplasmic CMS involving perennial species, and also provide unique ornamental flower types and CMS sources for hybrid sunflower breeding.

We characterized the inheritance of black and violet immature pepper fruit colour and chlorophyll, carotenoid and anthocyanin pigments responsible for fruit colour. Segregation for black vs. violet fruit colour deviated from expectations for simple inheritance. The primary determinant of fruit colour was the concentration of chlorophyll and carotenoid pigments relative to anthocyanin concentration. Whereas anthocyanin concentration was 34% greater in violet fruit, chlorophyll and carotenoid concentrations were 20-fold and fourfold greater, respectively, in black fruit relative to concentrations found in violet fruit. Measurement of Commission Internationale d'Eclairage (CIE) colour space scores revealed larger a* values and smaller b* values for violet fruit relative to corresponding parameters for black fruit. An additive-dominance model was sufficient to explain the variation in individual fruit pigments as well as the CIE parameter a*. Addition of additivexadditive effects to the additive-dominance model resulted in the best-fit model m[d][h][i] for L* and b* colour space parameters. For all pigment classes, significant additive effects contributed to the genetic variance for fruit colour.

Effects of marination on muscle shear force were also determined. Early-deboned (2 h postmortem) broiler butterfly fillets were visually selected based on their color lightness (pale, normal, and dark) from a commercial plant. The individual butterfly fillets were separated into left and right fillets. One of them was used for 6-h marination treatment and the other for 24-h marination treatment. Samples were marinated in a vacuum tumbler (-0.6 atm, 16 rpm, 20 min) with 20% wt/wt marinade yielding 0.75% NaCl and 0.45% phosphate in the final product. The effect of aging on salt-induced water gain by breast muscle was also measured using the swelling/centrifuging method. Marinade uptake, marinade retention, raw product yield, and cooked product yield were determined after tumbling, following storage for 24 and 48 h after marination and after cooking. Salt-induced water gain was greater (P < 0.05) in nonmarinated fillets at 24 h postmortem compared with 6 h postmortem. Compared with unmarinated fillets, marination enhanced finished product yield significantly (P < 0.05) regardless of postmortem aging and color lightness. Marinade retention and product yield were different (P < 0.05) in fillets categorized by L* (lightness) values. There were no differences (P > 0.05) between 2 postmortem aging times for marinade uptake, overall product yield, cooking loss, final cooked product yield, or meat shear force regardless of initial fillet L* values. However, marinade retention of 6-h samples was significantly better than 24-h samples (P < 0.05). These results demonstrate that with a targeted 15% marinade uptake, postmortem aging of 2-h deboned fillets before marination does not affect marinade uptake and product yield, but significantly affects marinade retention by boneless skinless chicken breast.

TI Horizontal transmission of Salmonella Enteritidis in experimentally infected laying hens housed in conventional or enriched cages SO POULTRY SCIENCE LA English DT Article DE Salmonella Enteritidis; chicken; horizontal transmission; conventional cage; enriched cage ID ENTERICA SEROVAR ENTERITIDIS; DIFFERENT HOUSING SYSTEMS; NATIONAL CONTROL PROGRAM; RISK-FACTORS; REPRODUCTIVE-TRACT; EGG CONTAMINATION; LAYER FARMS; OBLIGATORY VACCINATION; INTERNAL ORGANS; COLONIZATION AB The majority of human illnesses caused by Salmonella Enteritidis are attributed to contaminated eggs, and the prevalence of this pathogen in commercial laying flocks has been identified as a leading epidemiologic risk factor. Flock housing and management systems can affect opportunities for the introduction, transmission, and persistence of foodborne pathogens in poultry. The animal welfare implications of different types of housing for laying hens have been widely discussed in recent years, but the food safety consequences of these production systems remain incompletely understood. The present study assessed the effects of 2 different housing systems (conventional cages and colony cages enriched with perching and nesting areas) on the horizontal transmission of experimentally introduced Salmonella Enteritidis infection within groups of laying hens. In each of 2 trials, 136 hens were distributed among cages of both housing systems and approximately one-third of the hens in each cage were orally inoculated with doses of 108 cfu of Salmonella Enteritidis (phage type 13a in one trial and phage type 4 in the other). At regular intervals through 23 d postinoculation, cloacal swabs were collected from all hens (inoculated and uninoculated) and cultured for Salmonella Enteritidis. Horizontal contact transmission of infection was observed for both Salmonella Enteritidis strains, reaching peak prevalence values of 27.1% of uninoculated hens in conventional cages and 22.7% in enriched cages. However, no significant differences (P > 0.05) in the overall frequencies of horizontal Salmonella Enteritidis transmission were evident between the 2 types of housing. These results suggest that opportunities for Salmonella Enteritidis infection to spread horizontally throughout laying flocks may be similar in conventional and enriched cage-based production systems.

Sarcocystosis was diagnosed in a stillborn lamb with microscopic lesions predominantly in the central nervous system and placenta. Encephalitis was characterized by multiple foci of glial nodules some with central necrosis, perivascular cuffing and vascular occlusion, while placental lesions consisted of multifocal necroses, inflammation and mild calcification. Immature and mature schizonts were found in vascular endothelium of several organs. It is suggested that the protozoa were Sarcocystis tenella based on their morphology, location and as this is the most pathogenic Sarcocystis sp. parasitizing sheep. C1 [Agerholm, J.

Live attenuated marker vaccines that confer effective protection against the disease and allow differentiation between infected and vaccinated animals (DIVA) could impact CSF control policies. Previously, we reported the development of FlagT4 virus (FlagT4v), a rationally designed live attenuated marker vaccine. During its vaccine assessment, FlagT4v reverted to a virulent virus during successive passages in piglets. Sequence analysis revealed deletions and substitutions almost exclusively in the areas of El and E2. To improve genetic stability of FlagT4v, we introduced changes in the codon usage in those areas. The newly developed virus, FlagT4Gv, was shown to retain the attenuated phenotype after successive passages in piglets. As observed with FlagT4v, the newly developed FlagT4Gv conferred effective protection against challenge with virulent CSFV at early (7 days) and at late (28 days) times post-vaccination.

Conversely, whole inactivated virus (WIV) vaccines have the potential risk of vaccine-associated enhanced respiratory disease (VAERD) when challenged with IAV of substantial antigenic drift. A temperature sensitive, intranasal H1N2 LAIV was compared to wild type exposure (WT) and an intramuscular WIV vaccine in a model shown to induce VAERD. WIV vaccinated swine challenged with pandemic A/H1N1 (H1N1pdm09) were not protected from infection and demonstrated severe respiratory disease consistent with VAERD. Lung lesions were mild and challenge virus was not detected in the respiratory tract of LAIV vaccinates. High levels of post-vaccination IgG serum antibodies targeting the H1N1pdm09 HA2 stalk domain were exclusively detected in the WIV group and associated with increased H1N1pdm09 virus infectivity in MDCK cells. In contrast, infection-enhancing antibodies were not detected in the serum of LAIV vaccinates and VAERD was not observed. Published by Elsevier Inc.

TI Meta-analysis of genome-wide association studies for circulating phylloquinone concentrations SO AMERICAN JOURNAL OF CLINICAL NUTRITION LA English DT Article DE GWAS; phylloquinone; vitamin K; CYP4F2; genetics ID BONE-MINERAL DENSITY; VITAMIN-K STATUS; SERUM UNDERCARBOXYLATED OSTEOCALCIN; FOOD-FREQUENCY QUESTIONNAIRE; COMMUNITY-DWELLING ADULTS; BIOCHEMICAL MEASURES; BODY-COMPOSITION; ATHEROSCLEROSIS MESA; COMMON VARIANTS; HIP FRACTURE AB Background: Poor vitamin K status is linked to greater risk of several chronic diseases. Age, sex, and diet are determinants of circulating vitamin K; however, there is still large unexplained interindividual variability in vitamin K status. Although a strong genetic component has been hypothesized, this has yet to be examined by a genome-wide association (GWA) study. Objective: The objective was to identify common genetic variants associated with concentrations of circulating phylloquinone, the primary circulating form of vitamin K. Design: We conducted a 2-stage GWA meta-analysis of circulating phylloquinone in 2 populations of European descent from the Cohorts for Heart and Aging Research in Genomic Epidemiology Consortium Nutrition Working Group. Circulating phylloquinone was measured by using reversed-phase high-performance liquid chromatography. Results from adjusted cohort-specific discovery GWA analyses were meta-analyzed with inverse variance weights (n = 2138). Associations with circulating phylloquinone at P < 1 X 10(-6) were then evaluated in a second-stage analysis consisting of one independent cohort (n= 265). Results: No significant association was observed for circulating phylloquinone at the genome-wide significance level of 5 X 10(-8). However, from the discovery GWA, there were 11 single-nucleotide polymorphism (SNP) associations with circulating phylloquinone at P < 1 X 10(-6), including a functional variant previously associated with warfarin dose and altered phylloquinone metabolism. These SNPs are on 5 independent loci on 11q23.3, 8q24.3, 5q22.3, 2p12, and 19p13.12, and they fall within or near the candidate genes AP0A1/C3/A4/A5 cluster (involved in lipoprotein metabolism), COL22A1, CDO1, CTNAA2, and CYP4F2 (a phylloquinone oxidase), respectively. Second-stage analysis in an independent cohort further suggests the association of the 5q22.3 locus with circulating phylloquinone (P < 0.05). Conclusions: Multiple candidate genes related to lipoprotein and vitamin K metabolism were identified as potential determinants of circulating phylloquinone. Further investigation with a larger sample is warranted to verify our initial findings and identify other loci contributing to circulating phylloquinone.

TI Bioavailability of enteric-coated microencapsulated calcium during pregnancy: a randomized crossover trial in Bangladesh SO AMERICAN JOURNAL OF CLINICAL NUTRITION LA English DT Article DE calcium; fractional absorption; micronutrient supplementation; pregnancy; stable isotopes ID IRON-ABSORPTION; HEME-IRON; WOMEN; SUPPLEMENTATION; SOLUBILITY; METABOLISM; CARBONATE; CHILDREN; NONHEME; HUMANS AB Background: Prenatal calcium and iron supplements are recommended in settings of low dietary calcium intake and high prevalence of anemia. However, calcium administration may inhibit iron absorption. To overcome calcium-iron interactions, we developed a multi-micronutrient powder containing iron (60 mg), folic acid (400 mu g), and calcium carbonate granules microencapsulated with a pH-sensitive enteric coating to delay intestinal release. Objectives: We aimed to establish in vivo evidence that enteric-coated (EC) calcium is bioavailable in pregnant women and to explore the dose-responsiveness of fractional calcium absorption (FCA) in pregnancy. Design: This was a randomized crossover trial in pregnant women (26-28 wk of gestation) in Dhaka, Bangladesh. Participants were allocated to 1 of 3 dose groups (500, 1000, or 1500 mg elemental Ca). FCA was estimated in random order for EC and non-EC (control) granules by a dual-stable-isotope method (Ca-44-labeled granules and intravenous Ca-42) on the basis of the relative recovery of Ca-44 compared with Ca-42 in urine over 48 h. Results: Forty-nine participants with FCA for both EC and non-EC granules were included in the primary analyses. FCA geometric means were as follows: 21.8% (500 mg), 9.2% (1000 mg), and 11.7% (1500 mg) for non-EC granules compared with 3.3% (500 mg), 1.2% (1000 mg), and 2.1% for EC granules. Cumulative 48-h FCA of EC calcium was 85% lower (P < 0.001) than that of non-EC calcium, after adjustment for dose. In comparison to 500 mg, the FCA for the 1000-mg dose was 61% lower (P < 0.001) and was 42% lower (P = 0.002) for the 1500-mg dose, after adjustment for formulation. Conclusions: A pH-sensitive enteric coating substantially reduced calcium absorption from a prenatal multi-micronutrient powder. In its current formulation, this novel supplement is not suitable for clinical use. FCA was highly dose-dependent, such that doses of 1000 and 1500 mg delivered only negligibly more bioavailable calcium than the 500-mg dose.

Fermentation of such a highly concentrated lactose solution was possible due to simultaneous product removal using a pervaporation membrane. In this system, a productivity of 0.43 g L-1 h(-1) was obtained which is 307 % of that achieved in a non-product removal batch reactor (0.14 g L-1 h(-1)) where approximately 60 g L-1 whey permeate lactose was fermented. The productivity obtained in this system is much higher than that achieved in other product removal systems (perstraction 0.21 g L-1 h(-1) and gas stripping 0.32 g L-1 h(-1)). This membrane was also used to concentrate butanol from approximately 2.50 g L-1 in the reactor to 755 g L-1. Using this membrane, ABE selectivities and fluxes of 24.4-44.3 and 0.57-4.05 g m(-2) h(-1) were obtained, respectively. Pervaporation restricts removal of water from the reaction mixture thus requiring significantly less energy for product recovery when compared to gas stripping. C1 [Maddox, I.

Freshwater fish species store and use VA in the form of retinol (ROL), as well as uncommon forms such as 3,4-didehydroretinol (DROL) and 3-hydroxyretinol (3ROL). We developed and validated an HPLC method capable of measuring ROL, DROL and 3ROL in the feed and tissues of North American freshwater fish, for which little information on retinoid concentrations is available. DROL and ROL were higher than expected in both fish feed and fish liver (at 9.5-29.6 mg kg(-1) DROL and 26.9-79.2 mg kg(-1) ROL for feed; and 19.8-548.8 mu g g(-1) DROL and 10.4-128.8 mu g g(-1) ROL for liver). Interestingly, DROL concentrations were lower than ROL in fish feed, but often substantially higher in fish liver. Concentrations of ROL and DROL were similar to each other in muscle. 3ROL was detected in fish liver only. To our knowledge, this is the first publication to measure DROL concentrations in North American farm-raised fish and commercial fish feed. Monitoring of not only ROL, but DROL and 3ROL as well, may be advisable to better assess the VA content of fish feed and tissue. C1 [La Frano, M. R.; Burri, B.

TI Synthesis and characterization of norbelladine, a precursor of Amaryllidaceae alkaloid, as an anti-inflammatory/anti-COX compound SO BIOORGANIC & MEDICINAL CHEMISTRY LETTERS LA English DT Article DE Norbelladine; Chemical synthesis; NMR; Radicals; COX; NF-kappa B ID OXIDATIVE STRESS; CYCLOOXYGENASE-2; SYNTHASE; INFLAMMATION; DYSFUNCTION; DISEASES; OBESITY AB Rising ROS and systemic inflammation is often a serious concern in many disease conditions including obesity. Therefore, compounds with both anti-oxidant and anti-inflammatory activities are considered beneficial in preventing/treating several human chronic diseases. Norbelladine is an amine compound, a precursor for Amaryllidaceae alkaloids (e.g., belladine, crinamine, lycorine, and galanthamine) found in plants traditionally used for treating a variety of human diseases. However, little information is available about its potential health effects. Therefore, the amine was first synthesized, and its anti-oxidant and anti-inflammatory activities were investigated in this study. Also, the potential effects of the amine on NF-kappa B activation were investigated due to the critical involvement of ROS in the activation. Norbelladine was synthesized with more than 60% yield, analyzed by a HPLC method, and verified using NMR spectroscopic method. Then, its radical scavenging activity was investigated using DPPH-and superoxide radical assays. At the concentration of 10 mu M, norbelladine was a compound able to quench DPPH-radical by 31% (P < 0.05) and reduce superoxide radicals from xanthine oxidase by 33% (P < 0.05). At the concentration of 0.25 mu M, the amine also inhibited both COX-1 and COX-2 enzymes by 51% and 25% (P < 0.05), respectively. Furthermore, at the concentration of 10 mu M, norbelladine inhibited NF-kappa B activation by 23% (P < 0.05). In summary, the data suggests that norbelladine may be a compound to quench radicals, inhibit COX enzymes as well as suppress NF-kappa B activation at relatively lower concentrations.

The more wide-ranging P.sargentii also occurs on the island. Population genetic diversity and structure of Pseudophoenix was investigated using ten microsatellite loci. The study focused on populations from Hispaniola, but also included samples from other Caribbean islands. Results showed homozygote excess and high inbreeding coefficients in all populations across all polymorphic loci. Populations were highly differentiated. Results from both Bayesian and neighbour-joining cluster analyses identified groups that were consistent with currently accepted species delimitations. We included the only known population of a possible undescribed taxon from the Dominican Republic. Results from the cluster analyses suggested that this putative taxon is closely related to P.sargentii from the Turks and Caicos Islands. There was no significant correlation between population size and observed heterozygosity. Contrary to what was anticipated, protected areas do not harbour most of the genetic diversity of the genus. The Haitian endemic P.lediniana should have the highest priority for conservation because it is restricted to a single population, it has a small number of individuals and it exhibited reduced levels of genetic diversity. The putative new taxon from the Dominican Republic has similar conservation concerns. Future conservation efforts should aim to maintain population connectivity and increase population size, particularly targeting populations with low genetic diversity.(c) 2014 The Linnean Society of London, Botanical Journal of the Linnean Society, 2014, 176, 469-485.

Male beetles were distinguished by a sclerotised, reticulate ninth abdominal sternite. In females, the distinct ovipositor (tergite, valvifers (ninth sternite), and laterotergites of the ninth abdominal segment) was visible. The procedure was rapid and harmed only a small number of individuals (fewer than 5%). C1 [Shepherd, William P.; Sullivan, Brian T.] US Forest Serv, USDA, Southern Res Stn, Pineville, LA 71360 USA.

SCNF were mechanically isolated from hard wood pulp after enzymatic pretreatment. Various levels of SCNF were added to an aqueous PVA solution, which was gel-spun into continuous fibers. The molecular orientation of PVA was affected by a combination of wet drawing during gel spinning and post-hot-drawing at a high temperature after drying. A maximum total draw ratio of 27 was achieved with various SCNF contents investigated. The PVA crystal orientation increased when small amounts of SCNF were added, but decreased again as the SCNF content was increased above about 2 or 3 %, likely due to SCNF percolation resulting in network formation that inhibited alignment. SCNF fillers were effective in improving PVA fiber tensile properties (i.e., ultimate strength and elastic modulus). For example, the ultimate strength and modulus of PVA/SCNF composite fiber with a SCNF weight ratio of 6 were nearly 60 and 220 % higher than that of neat PVA. Shifts in the Raman peak at similar to 1,095 cm(-1), which were associated with the C-O-C glycosidic bond of SCNF, indicated good stress-transfer between the SCNF and the PVA matrix due to strong interfacial hydrogen bonding. Cryogenic fractured scanning electron microscopy images of filled and unfilled PVA fibers showed uniform SCNF dispersion.

The results from this trial suggest that intensive lifestyle interventions are effective in helping patients to achieve management of cardiovascular risk factors and reducing the need to initiate medication usage to manage these conditions, though the benefits in terms of the prevention of CVD morbidity and mortality beyond those achieved through aggressive medical management of hypertension and dyslipidemia is not clear. Additional benefits of participation in an intensive lifestyle intervention such as lowered chronic kidney disease risk, blood pressure, medication usage, improved sleep apnea, and partial remission of diabetes are discussed.

The blade tilts back to photosynthesize and the sheath wraps around the stem to provide structural support and protect young leaves. At the junction between blade and sheath are the ligule and auricles, both of which are absent in the recessive liguleless1 (lg1) mutant. Using an antibody against LG1, we reveal LG1 accumulation at the site of ligule formation and in the axil of developing tassel branches. The dominant mutant Wavy auricle in blade1 (Wab1-R) produces ectopic auricle tissue in the blade and increases the domain of LG1 accumulation. We determined that wab1 encodes a TCP transcription factor by positional cloning and revertant analysis. Tassel branches are few and upright in the wab1 revertant tassel and have an increased branch angle in the dominant mutant. wab1 mRNA is expressed at the base of branches in the inflorescence and is necessary for LG1 expression. wab1 is not expressed in leaves, except in the dominant mutant. The domain of wab1 expression in the Wab1-R leaf closely mirrors the accumulation of LG1. Although wab1 is not needed to induce lg1 expression in the leaf, LG1 is needed to counteract the severe phenotype of the dominant Wab1-R mutant. The regulatory interaction of LG1 and WAB1 reveals a link between leaf shape and tassel architecture, and suggests the ligule is a boundary similar to that at the base of lateral organs.

However, data from long-term trials are lacking. The Vitamin D and Type 2 Diabetes (D2d) study is a randomized clinical trial designed to examine whether a causal relationship exists between vitamin D supplementation and the development of diabetes in people at high risk for type 2 diabetes. RESEARCH DESIGN AND METHODS D2d was designed with support from a U34 planning grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). The final protocol was approved by the D2d Research Group, the data and safety monitoring board, and NIDDK. Key eligibility criteria are age 30 years, BMI of 24(22.5 for Asian Americans) to 42 kg/m(2), increased risk for diabetes (defined as meeting two of three glycemic criteria for prediabetes established by the American Diabetes Association [fasting glucose 100-125 mg/dL (5.5-6.9 mmol/L), 2-h postload glucose after 75-g glucose load 140-199 mg/dL (7.7-11.0 mmol/L), hemoglobin A(1c), 5.7-6.4% (39-46 mmol/mol)]), and no hyperparathyroidism, nephrolithiasis, or hypercalcemia. D2d participants are randomized to once-daily vitamin D-3 (cholecalciferol 4,000 IU) or placebo and followed for an average of 3 years. The primary end point is time to incident diabetes as assessed by laboratory criteria during the study or by adjudication if diagnosed outside of D2d. Recruitment was initiated at the end of 2013. CONCLUSIONS D2d will test whether vitamin D supplementation is safe and effective at lowering the risk of progression to diabetes in people at high risk for type 2 diabetes.

Chazdon, Robin TI Decomposing biodiversity data using the Latent Dirichlet Allocation model, a probabilistic multivariate statistical method SO ECOLOGY LETTERS LA English DT Article DE Biodiversity data; cluster analysis; community ecology; Latent Dirichlet Allocation; multivariate statistics; text-mining ID ECOLOGY AB We propose a novel multivariate method to analyse biodiversity data based on the Latent Dirichlet Allocation (LDA) model. LDA, a probabilistic model, reduces assemblages to sets of distinct component communities. It produces easily interpretable results, can represent abrupt and gradual changes in composition, accommodates missing data and allows for coherent estimates of uncertainty. We illustrate our method using tree data for the eastern United States and from a tropical successional chronosequence. The model is able to detect pervasive declines in the oak community in Minnesota and Indiana, potentially due to fire suppression, increased growing season precipitation and herbivory. The chronosequence analysis is able to delineate clear successional trends in species composition, while also revealing that site-specific factors significantly impact these successional trajectories. The proposed method provides a means to decompose and track the dynamics of species assemblages along temporal and spatial gradients, including effects of global change and forest disturbances.

For 57 co-occurring native and exotic plant species from an old field in Canada, we collected a data set on the effects of threesoil biota treatments on plant growth: net whole-soil feedback (combined effects of mutualists and antagonists), feedback with arbuscular mycorrhizal fungi (AMF) collected from soils of conspecific plants, and feedback with Glomus etunicatum, a dominant mycorrhizal fungus. We found phylogenetic signal in both net whole-soil feedback and feedback with AMF of conspecifics; conservatism was especially strong among native plants but absent among exotics. The abundance of plants in the field was also conserved, a pattern underlain by shared plant responses to soil biota. We conclude that soil biota influence the abundance of close plant relatives in nature. C1 [Anacker, Brian L.; Strauss, Sharon Y.] Univ Calif Davis, Dept Ecol & Evolut, Davis, CA 95616 USA.

Amyelois transitella moths have proven difficult to monitor and control for over 5 decades; however, recent reports indicate progress towards attractants using pheromone or semiochemical blends. Despite advances of a host plant volatile attractant blend that is effective for monitoring moth populations in almond orchards, the blend's attractancy and capture efficacy of A.transitella has not translated to pistachio orchards. The apparent orchard specificity of A.transitella to the blend suggests a different composition of host plant volatiles is needed to either improve the current blend or a new blend formulation is required for monitoring in pistachio orchards. One objective of this study was to evaluate available individual host volatiles via a standardised puff method in combination with electroantennographic analysis. In total 105 volatiles were evaluated individually for their ability to elicit an electrophysiological chemoreception response from excised male and female A.transitella antennae. Male antennae responded significantly higher to alcohols, aldehydes, alkyls, aromatics, and ketones. Female antennae responded significantly higher to benzenoids, monoterpenes, sesquiterpenes, and short-chain alcohols.

TI Family Forest Landowners' Interest in Forest Carbon Offset Programs: Focus Group Findings from the Lake States, USA SO ENVIRONMENTAL MANAGEMENT LA English DT Article DE Forest carbon offsets; Family forest owners; Carbon management; Voluntary carbon markets; Focus groups; Lake states ID OWNERS; TYPOLOGY AB In 2012, focus groups were organized with individuals owning 20+ acres in the Lake States region of the United States (Michigan, Minnesota, and Wisconsin) to discuss various issues related to forest carbon offsetting. Focus group participants consisted of landowners who had responded to an earlier mail-back survey (2010) on forest carbon offsets. Two focus groups were held per state with an average of eight participants each (49 total). While landowner participant types varied, overall convergence was reached on several key issues. In general, discussion results found that the current payment amounts offered for carbon credits are not likely, on their own, to encourage participation in carbon markets. Landowners are most interested in other benefits they can attain through carbon management (e.g., improved stand species mix, wildlife, and trails). Interestingly, landowner perceptions about the condition of their own forest land were most indicative of prospective interest in carbon management. Landowners who felt that their forest was currently in poor condition, or did not meet their forest ownership objectives, were most interested in participating. While the initial survey sought landowner opinions about carbon markets, a majority of focus group participants expressed interest in general carbon management as a means to achieve reduced property taxes.
