Visible leaf injury, dry weight, chlorophyll, carotenoid content, leaf greenness (SPAD value), quantum yield of photosynthesis, and stomatal resistance were measured to evaluate response. Shoot biomass, total chlorophyll, leaf greenness, and carotenoid content were reduced in ozone-exposed plants. Based on the results of principal component analysis (PCA)-biplot analysis, the order of sensitivity to ozone was: Akbar>>Sufi >= Bijoy >= Shatabdi> Bari-26 >= Gourab>Bari-25 >= Prodip >= Sourav>>Kanchan. The most important parameters to discriminate cultivars with respect to ozone sensitivity were visible injury and chlorophyll b/a ratio, whereas quantum yield of photosynthesis was less important. Differences in stomatal resistance were not a significant factor in ozone response. Regression of cultivars' PCA scores against year of release revealed no trend, suggesting that ozone tolerance was not incorporated during cultivar breeding.

TI Age and growth in the Australian freshwater mussel, Westralunio carteri, with an evaluation of the fluorochrome calcein for validating the assumption of annulus formation SO FRESHWATER SCIENCE LA English DT Article DE life history; growth rate; von Bertalanffy; Hyriidae; Unionoida; Unionida; Australia ID BIVALVIA UNIONOIDA HYRIIDAE; BURROWING BIVALVES; CLIMATE-CHANGE; UNIONIDAE; SHELL; MARKER; ECOSYSTEMS; LONGEVITY; IREDALE AB Growth and longevity of freshwater mussels (Unionida) are important for defining life-history strategies and assessing vulnerability to human impacts. We used mark-recapture and analysis of shell rings to investigate age and growth of the hyriid, Westralunio carteri, at 5 sites in southwestern Australia. We tested the utility of the in situ marker calcein for validating the assumption of annulus formation in adults. Calcein was incorporated into the shells of all recovered individuals, but it provided an interpretable reference mark in only 4 of 16 individuals. These 4 individuals produced 1 shell ring subsequent to the mark, supporting the assumption of annulus production during the austral winter. Maximum age ranged among populations from 36 to 52 y and maximum size ranged from 72.9 to 82.8 mm. Mean age and length did not differ between sexes, and growth trajectories differed between sexes at only 1 site. Estimates of growth measured by the von Bertalanffy growth constant, K, ranged from 0.021 to 0.336 among sites. Estimates from mark-recapture experiments were 20 to 52% lower than values from shell annuli at all sites except 1 where K from shell annuli was similar to 1/2 that estimated from mark-recapture. Both methods showed a positive relationship between K and mean water temperature among sites, suggesting a role of riparian shading in regulating stream temperature, and hence, indirectly influencing mussel growth. Mussel growth and mean N or P concentrations were not related among sites, but total N at the site with highest mussel growth was >2x higher than at any other site. Westralunio carteri is a long-lived, slow-growing bivalve. Maximum age, K, and probable age at maturity (4-6 y) are similar to other slow-growing freshwater bivalve groups. This suite of life-history traits is considered an adaptation for stable aquatic habitats. Therefore, W. carteri can be expected to adapt poorly to human impacts, such as riparian clearing and water extraction, which increase the temporal variability of environmental conditions in streams.

BATSCH; SPROUT GROWTH; BUD DORMANCY; RNA-SEQ; EXPRESSION; GENES; WALL; METHYLATION; LOCUS; CYCLE AB Perennial plants undergo repression of meristematic activity in a process called dormancy. Dormancy is a complex metabolic process with implications for plant breeding and crop yield. Endodormancy, a specific subclass of dormancy, is characteristic of internal physiological mechanisms resulting in growth suppression. In this study, we examine transcriptional changes associated with the natural cessation of endodormancy in potato tuber meristems and in endodormant tubers treated with the cytokinin analog 1-(alpha-ethylbenzyl)-3-niroguanidine (NG), which terminates dormancy. RNA-sequencing was used to examine transcriptome changes between endodormant and non-dormant meristems from four different harvest years. A total of 35,091 transcripts were detected with 2132 differentially expressed between endodormant and non-dormant tuber meristems. Endodormant potato tubers were treated with the synthetic cytokinin NG and transcriptome changes analyzed using RNA-seq after 1, 4, and 7 days following NG exposure. A comparison of natural cessation of dormancy and NG-treated tubers demonstrated that by 4 days after NG exposure, potato meristems exhibited transcriptional profiles similar to the non-dormant state with elevated expression of multiple histones, a variety of cyclins, and other genes associated with proliferation and cellular replication. Three homologues encoding for CYCD3 exhibited elevated expression in both non-dormant and NG-treated potato tissues. These results suggest that NG terminates dormancy and induces expression cell cycle-associated transcripts within 4 days of treatment.

TI Systematic differences in the response of genetic variation to pedigree and genome-based selection methods SO HEREDITY LA English DT Article ID QUANTITATIVE TRAIT LOCUS; POSITIVE SELECTION; CHICKEN; HITCHHIKING; PROGRAMS; SIZE AB Genomic selection (GS) is a DNA-based method of selecting for quantitative traits in animal and plant breeding, and offers a potentially superior alternative to traditional breeding methods that rely on pedigree and phenotype information. Using a 60 K SNP chip with markers spaced throughout the entire chicken genome, we compared the impact of GS and traditional BLUP (best linear unbiased prediction) selection methods applied side-by-side in three different lines of egg-laying chickens. Differences were demonstrated between methods, both at the level and genomic distribution of allele frequency changes. In all three lines, the average allele frequency changes were larger with GS, 0.056 0.064 and 0.066, compared with BLUP, 0.044, 0.045 and 0.036 for lines B1, B2 and W1, respectively. With BLUP, 35 selected regions (empirical P<0.05) were identified across the three lines. With GS, 70 selected regions were identified. Empirical thresholds for local allele frequency changes were determined from gene dropping, and differed considerably between GS (0.167-0.198) and BLUP (0.105-0.126). Between lines, the genomic regions with large changes in allele frequencies showed limited overlap. Our results show that GS applies selection pressure much more locally than BLUP, resulting in larger allele frequency changes. With these results, novel insights into the nature of selection on quantitative traits have been gained and important questions regarding the long-term impact of GS are raised. The rapid changes to a part of the genetic architecture, while another part may not be selected, at least in the short term, require careful consideration, especially when selection occurs before phenotypes are observed.

TI Visual Reconciliation of Alternative Similarity Spaces in Climate Modeling SO IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS LA English DT Article DE Similarity; clustering; matrix; optimization; climate model ID VISUALIZATION; EXPLORATION; CLUSTERINGS; GENERATION AB Visual data analysis often requires grouping of data objects based on their similarity. In many application domains researchers use algorithms and techniques like clustering and multidimensional scaling to extract groupings from data. While extracting these groups using a single similarity criteria is relatively straightforward, comparing alternative criteria poses additional challenges. In this paper we define visual reconciliation as the problem of reconciling multiple alternative similarity spaces through visualization and interaction. We derive this problem from our work on model comparison in climate science where climate modelers are faced with the challenge of making sense of alternative ways to describe their models: one through the output they generate, another through the large set of properties that describe them. Ideally, they want to understand whether groups of models with similar spatio-temporal behaviors share similar sets of criteria or, conversely, whether similar criteria lead to similar behaviors. We propose a visual analytics solution based on linked views, that addresses this problem by allowing the user to dynamically create, modify and observe the interaction among groupings, thereby making the potential explanations apparent. We present case studies that demonstrate the usefulness of our technique in the area of climate science.

However, the peptide-binding specificity of cattle MHC (bovine leucocyte antigen, BoLA) class I (BoLA-I) molecules remains poorly characterized. Here, we demonstrate how a combination of high-throughput assays using positional scanning combinatorial peptide libraries, peptide dissociation, and peptide-binding affinity binding measurements can be combined with bioinformatics to effectively characterize the functionality of BoLA-I molecules. Using this strategy, we characterized eight BoLA-I molecules, and found the peptide specificity to resemble that of human MHC-I molecules with primary anchors most often at P2 and P9, and occasional auxiliary P1/P3/P5/P6 anchors. We analyzed nine reported CTL epitopes from Theileria parva, and in eight cases, stable and high affinity binding was confirmed. A set of peptides were tested for binding affinity to the eight BoLA proteins and used to refine the predictors of peptide-MHC binding NetMHC and NetMHCpan. The inclusion of BoLA-specific peptide-binding data led to a significant improvement in prediction accuracy for reported T. parva CTL epitopes. For reported CTL epitopes with weak or no predicted binding, these refined prediction methods suggested presence of nested minimal epitopes with high-predicted binding affinity. The enhanced affinity of the alternative peptides was in all cases confirmed experimentally. This study demonstrates how biochemical high-throughput assays combined with immunoinformatics can be used to characterize the peptide-binding motifs of BoLA-I molecules, boosting performance of MHC peptide-binding prediction methods, and empowering rational epitope discovery in cattle.

We compare estimates of genetic parameters by fitting multivariate Normal (MN) or heavy-tail distributions (multivariate Student's t and multivariate Slash, MSt and MS) for residuals in data of hot carcass weight (HCW), longissimus muscle area (REA) and 12th to 13th rib fat (FAT) traits in beef cattle using 2475 records from 2007 to 2008 from a large commercial operation in Nebraska. Model comparisons using deviance information criteria (DIC) favoured MSt over MS and MN models, respectively. The posterior means (and 95% posterior probability intervals, PPI) of v for the MSt and MS models were 5.89 +/- 0.90 (4.35, 7.86) and 2.04 +/- 0.18 (1.70, 2.41), respectively. Smaller values of posterior densities of v for MSt and MS models confirm that the assumption of normally distributed residuals is not adequate for the analysis of the data set. Posterior mean (PM) and posterior median (PD) estimates of direct genetic variances were variable with MSt having the highest mean value followed by MS and MN, respectively. Posterior inferences on genetic variance were, however, comparable among the models for FAT. Posterior inference on additive heritabilities for HCW, REA and FAT using MN, MSt and MS models indicated similar and moderate heritability comparable with the literature. Posterior means of genetic correlations for carcass traits were variable but positive except for between REA and FAT, which showed an antagonistic relationship. We have demonstrated that genetic evaluation and selection strategies will be sensitive to the assumed model for residuals. C1 [Peters, S. O.] Berry Coll, Dept Anim Sci, Mt Berry, GA 30149 USA.

Two phenotypic assays (1% glycine tolerance and H2S production) were described to differentiate the subspecies. Multiple molecular assays have been applied to differentiate the C. fetus subspecies, but none of these tests is consistent with the phenotypic identification methods. In this study, we defined the core genome and accessory genes of C. fetus, which are based on the closed genomes of five C. fetus strains. Phylogenetic analysis of the core genomes of 23 C. fetus strains of the two subspecies showed a division into two clusters. The phylogenetic core genome clusters were not consistent with the phenotypic classifications of the C. fetus subspecies. However, they were consistent with the molecular characteristics of the strains, which were determined by multilocus sequence typing, sap typing, and the presence/absence of insertion sequences and a type I restriction modification system. The similarity of the genome characteristics of three of the phenotypically defined C. fetus subsp. fetus strains to C. fetus subsp. venerealis strains, when considering the core genome and accessory genes, requires a critical evaluation of the clinical relevance of C. fetus subspecies identification by phenotypic assays.

TI Effect of sprouted barley grain supplementation of an herbage-based or haylage-based diet on ruminal fermentation and methane output in continuous culture SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE continuous culture fermentation; grazing; sprouted barley ID LACTATING DAIRY-COWS; BACTERIAL PROTEIN-SYNTHESIS; TOTAL MIXED RATION; DRY-MATTER INTAKE; MILK-PRODUCTION; AMMONIA CONCENTRATION; NITROGEN-METABOLISM; PERENNIAL RYEGRASS; MICROBIAL-GROWTH; NUTRIENT CONTENT AB A 4-unit dual-flow continuous-culture fermentor system was used to assess the effect of supplementing 7-d sprouted barley (SB) or barley grain (BG) with an herbage-based or haylage-based diet on nutrient digestibility, volatile fatty acid (VFA) profiles, bacterial protein synthesis, and methane (CH4) output. Treatments were randomly assigned to fermentors in a 4 x 4 Latin square design with a 2 x 2 factorial arrangement using 7 d for diet adaptation and 3 d for sample collection. Experimental diets were (1) 55.5 g of herbage dry matter (DM) + 4.5 g of SB DM, (2) 56.0 g of herbage DM + 4.0 g of BG DM, (3) 55.5 g of haylage DM + 4.5 g of SB DM, and (4) 56.0 g of haylage DM + 4.0 g of BG DM. Forages were fed at 0730, 1030, 1400, and 1900 h, whereas SB and BG were fed at 0730 and 1400 h. Gas samples for CH4 analysis were collected at 0725, 0900, 1000, 1355, 1530, and 1630 h on d 8, 9, and 10. Fluid samples were taken once daily on d 8, 9, and 10 for pH measurements and for ammonia-N and VFA analysis and analyzed for DM, organic matter, crude protein, neutral detergent fiber, and acid detergent fiber for determination of nutrient digestibilities and estimation of bacterial protein synthesis. Orthogonal contrasts were used to compare the effect of forage source (haylage vs. herbage), supplement (BG vs. SB), and the forage x supplement interaction. Apparent and true DM and organic matter digestibilities as well as apparent crude protein digestibility were not affected by forage source. However, true DM digestibility was greatest for diets supplemented with SB. Apparent neutral and acid detergent fiber digestibilities of herbage-based diets were higher than haylage-based diets but fiber digestibility was not affected by supplement. Diets supplemented with SB had higher mean and minimum pH than BG; however, maximum pH was not affected by diet. Supplementation with BG produced a greater concentration of total VFA compared with diets supplemented with SB. Haylage-based diets produced greater CH4 output compared with herbage-based diets but supplementation did not affect CH4 output. Efficiency of bacterial protein synthesis was greater for herbage-based diets compared with haylage-based diets, with no effect of supplementation. Overall, supplementation with SB marginally increased true DM digestibility of herbageand haylage-based diets but did not affect fiber and crude protein digestibilities, CH4 output, and bacterial efficiency, compared with BG.

Recent work has shown that silage VOC can contribute to poor air quality and reduce feed intake. Silage additives may reduce VOC production in silage by inhibiting the activity of bacteria or yeasts that produce them. We produced corn silage in 18.9-L bucket silos using the following treatments: (1) control (distilled water); (2) Lactobacillus buchneri 40788, with 400,000 cfu/g of wet forage; (3) Lactobacillus plantarum MTD1, with 100,000 cfu/g; (4) a commercial buffered propionic acid-based preservative (68% propionic acid, containing ammonium and sodium propionate and acetic, benzoic, and sorbic acids) at a concentration of 1 g/kg of wet forage (0.1%); (5) a low dose of potassium sorbate at a concentration of 91 mg/kg of wet forage (0.0091%); (6) a high dose of potassium sorbate at a concentration of 1 g/kg of wet forage (0.1%); and (7) a mixture of L. plantarum MTD1 (100,000 cfu/g) and a low dose of potassium sorbate (91 mg/kg). Volatile organic compound concentrations within silage were measured after ensiling and sample storage using a headspace gas chromatography method. The high dose of potassium sorbate was the only treatment that inhibited the production of multiple VOC. Compared with the control response, it reduced ethanol by 58%, ethyl acetate by 46%, and methyl acetate by 24%, but did not clearly affect production of methanol or 1-propanol. The effect of this additive on ethanol production was consistent with results from a small number of earlier studies. A low dose of this additive does not appear to be effective. Although it did reduce methanol production by 24%, it increased ethanol production by more than 2-fold and did not reduce the ethyl acetate concentration. All other treatments increased ethanol production at least 2-fold relative to the control, and L. buchneri addition also increased the 1-propanol concentration to approximately 1% of dry matter. No effects of any treatments on fiber fractions or protein were observed. However, L. buchneri addition resulted in slightly more ammonia compared with the control. If these results hold under different conditions, a high dose of potassium sorbate will be an effective treatment for reducing VOC production in and emission from silage. Regulations aimed at reducing VOC emission could be ineffective or even increase emission if they promote silage additives without recognition of different types of additives.

Model improvements included (1) multi-trait processing, (2) multiple fixed class and regression variables, (3) differing models for different traits, (4) random regressions, and (5) foreign data included using pseudo-records. Computational improvements included (6) parallel processing, (7) renumbering class variables to equation numbers within the program so that estimated effects are output with original identification numbers, and (8) reliability computed within the same program. When applied to 3 fertility traits of 27,971,895 cows and heifers, the new model used daughter pregnancy rate as a correlated trait to improve heifer and cow conception rate evaluations for older animals and in herd-years where records are missing, and also added information from crossbreds. When applied to 7 traits and 76,846,327 lactation records of 30,064,300 cows, gains in accuracy were small for yield and somatic cell score, moderate for daughter pregnancy rate, and larger for productive life for recent bulls compared with single-trait evaluations. For very old bulls, multi-trait gains were also large for protein because lactation records were available only for milk and fat. Multi-trait productive life was computed with exact rather than approximate methods; however, correlated information from conformation was excluded, reducing advantages of the new model over the previous software. Estimates of breed differences, inbreeding depression, and heterosis were similar to previous estimates; new estimates were obtained for conception rates. Predictions were compared by truncating 4 yr of data, and genetic trend validation was applied to all breed trait combinations. The estimates of trend account for increases in inbreeding across time. Incorporation of foreign data gave correlations above 0.98 for new with previous evaluations of foreign Holstein bulls, but lower for other breeds. The 7-trait model required 35 GB of memory and 3 d to converge using 7 processors. The new software was implemented for fertility traits in 2013 and is scheduled for implementation with yield, somatic cell score, and productive life in 2014. Further revision of the models and software may be needed in the near future to account for genomic preselection. C1 [VanRaden, P. M.; Tooker, M. E.; Wright, J. R.; Hutchison, J.

An open-path eddy covariance technique and a microclimate measurement system were deployed to investigate the WUE of a poplar plantation ecosystem in the Daxing District of Beijing, China, during the growing seasons in 2006, 2007, and 2008. We found that WUE values changed diurnally, peaking in early morning and showing a minimum between 2 pm and 3 pm. This pattern was regulated by photosynthetically active radiation, saturated vapor pressure deficit, and stomatal opening and closure. WUE had inter-daily variations but no substantial seasonal variation. The WUE decreased with increasing soil water content due to the higher sensitivity of ET than GEP to increased soil moisture. Under moist soil conditions (i.e., relative extractable water content > 0.4), GEP was stable and WUE was generally low. These results suggest that the poplar plantation does not effectively use the available soil water for carbon uptake, and that soil moisture is lost to the atmosphere through ET.

Stepped chutes applied to more moderate slopes like those for aging embankment dams are a growing trend, and research activities as a result have increased in this arena. Although numerous stepped chute design guidelines are available, some of them are complicated and somewhat cumbersome to use. A multiyear, large-scale physical model study was conducted for a broad range of step height (h) to critical flow depth (dc) ratio and chute slope () (i.e.,0.035h/dc2.27 and 14 degrees 26.6 degrees). The objectives of the study were to (1) evaluate the step height to critical flow depth ratio and the chute slope affect on the surface inception point, clear water and bulked flow depth, air concentration, and energy coefficient; and (2) develop practical, straight-forward design relationships for practicing engineers. Detailed flow measurements were collected during testing, and the results were compared in terms of free-surface inception point, air-water flow properties, and energy dissipation. Free-surface inception point relationships were validated for a broader range of use. Relationships for air concentration, clear water flow depth, and energy coefficient were developed, and findings showed these relationships are a function of (1) the length from the downstream edge of the broad-crested weir to the point of interest to the characteristic length from the downstream edge of the broad-crested weir to the free-surface inception point (L/Li) ratio, (2) the step height to critical flow depth (h/dc) ratio, and/or (3) the chute slope ().

Objective: Testing was conducted to determine the storage stability of lipoyl glycerides in phospholipid-based liposomes. Materials and methods: Lipoyl glycerides prepared by transesterification of lipoic acid with high oleic sunflower oil were incorporated into unilamellar liposomes comprised of soy phosphatidylcholine (soyPC) or dioleoylphosphatidylcholine (DOPC). Results: Lipoyl glycerides were stable in soyPC at 4 degrees C (90% remaining after five weeks) and decayed with a half-life (t(1/2)) of 14 d at 40 degrees C. In contrast, lipoyl glycerides embedded in DOPC were completely stable for four weeks at 40 degrees C. Dihydrolipoyl glycerides in soyPC converted to lipoyl glycerides at 4 degrees C (t(1/2) = 14 d) over four weeks, and much more rapidly so at 40 degrees C (t(1/2) = 1 d). A hydroperoxide accumulation analysis indicated that lipoyl glycerides and dihydrolipoyl glycerides were modified or degraded while suppressing autoxidation of the polyunsaturated fatty acids present in soyPC. Dynamic light scattering measurements found that liposomes containing lipoyl glycerides or dihydrolipoyl glycerides did not undergo significant size changes for at least 48 d, indicating that inclusion of the lipoic acid derivatives did not induce vesicle aggregation. Discussion/Conclusion: Substitution of the soyPC with DOPC, which is not readily subject to autoxidation, provided a much more stable storage environment for lipoyl glycerides. These findings confirm the expectation that phospholipid liposomes need to be oxidatively stable vehicles for dermal delivery of lipoic acid derivatives.

TI Predicting the Flexure Response of Wood-Plastic Composites from Uni-Axial and Shear Data Using a Finite-Element Model SO JOURNAL OF MATERIALS IN CIVIL ENGINEERING LA English DT Article DE Creep; Polymer; Composite materials; Finite element method; Data analysis; Creep; Wood-polymer composite; Power-law; Finite-element; Abaqus; Flexure; User-defined material model ID VISCOELASTICITY; POLYPROPYLENE; BEHAVIOR; CREEP; RATIO AB Wood-plastic composites (WPCs), commonly used in residential decks and railings, exhibit mechanical behavior that is bimodal, anisotropic, and nonlinear viscoelastic. They exhibit different stress-strain responses to tension and compression, both of which are nonlinear. Their mechanical properties vary with respect to extrusion direction, their deformation under sustained load is time-dependent (they experience creep), and the severity of creep is stress-dependent. Because of these complexities, it is beneficial to create a mechanics-based predictive model that will calculate the material's response in situations that are too difficult or expensive to test experimentally. Such a model would also be valuable in designing and optimizing new structural shapes. Analysis and prediction of WPC members begins with the time-dependent characterization of the material's axial and shear behaviors. The data must then be combined with a tool that can simulate mode-dependence, anisotropy, and nonlinear axial stress distributions that vary over the length of a member and evolve with time. Time-dependent finite-element (FE) modeling is the most practical way to satisfy all of these requirements. This paper presents an FE material model that was developed to predict the deflection of flexural members subjected to both quasi-static ramp loading and long-term creep. Predictions were made for six different WPC products, encompassing a variety of polymers and cross-sections. These predictions were compared with experimental testing and the model shows some success, particularly in the quasi-static response. Creep predictions were more accurate for solid polyethene-based materials than polypropylene-based hollow box sections. C1 [Hamel, Scott E.] Univ Alaska Anchorage, Anchorage, AK 99508 USA.

Methods: Serum 25(OH)D and PTH were measured at the 30- or 36-mo visit in 418 participants enrolled in the Osteoarthritis Initiative (OAI) who had >= 1 knee with both symptomatic and radiographic osteoarthritis. Progression of knee osteoarthritis was defined as any increase in the radiographic joint space narrowing (JSN) score between the 24- and 48-mo OAI visits. Results: The mean concentrations of serum 25(OH)D and PTH were 26.2 mu g/L and 54.5 mu g/mL, respectively. Approximately 16% of the population had serum 25(OH)D < 15 mu g/L. Between the baseline and follow-up visits, 14% progressed in JSN score. Participants with low vitamin D (25(OH)D < 15 mu g/L) had >2-fold elevated risk of knee osteoarthritis progression compared with those with greater vitamin D concentrations (>= 15 mu g/L OR: 2.3; 95% CI: 1.1, 4.5). High serum PTH (>= 73 pg/mL) was not associated with a significant increase in JSN score. However, participants with both low vitamin D and high PTH had >3-fold increased risk of progression (OR: 3.2; 95%CI: 1.2, 8.4). Conclusion: Our results suggest that individuals deficient in vitamin D have an increased risk of knee osteoarthritis progression.

Specifically, we report the computed temperature variation (up to 500 K) of the monoclinic cellulose I-beta lattice parameters, constant pressure heat capacity, C-p, entropy, S, enthalpy, H, the linear thermal expansion components, xi(I), and components of the isentropic and isothermal (single crystal) elastic stiffness matrices, C-ij(S)(T) and C-ij(T)(T), respectively. Thermodynamic quantities from phonon calculations computed with DFT and the supercell method provided necessary inputs to compute the temperature dependence of cellulose I-beta properties via the quasi-harmonic approach. The notable exceptions were the thermal conductivity components, lambda(i) (the prediction of which has proven to be problematic for insulators using DFT) for which the reverse, non-equilibrium molecular dynamics approach with a force field was applied. The extent to which anisotropy of Young's modulus and Poisson's ratio is temperature-dependent was explored in terms of the variations of each with respect to crystallographic directions and preferred planes containing specific bonding characteristics (as revealed quantitatively from phonon force constants for each atomic pair, and qualitatively from charge density difference contours). Comparisons of the predicted quantities with available experimental data revealed reasonable agreement up to 500 K. Computed properties were interpreted in terms of the cellulose I-beta structure and bonding interactions.

We investigated northern pocket gopher (Thomomys talpoides) effects on soil nutrient dynamics, soil physical properties, and plant communities on surfaces created by Mount St. Helens' 1980 eruption. For comparison to later successional systems, we summarized published studies on gopher effects on soil C and N and plant communities. In 2010, 18 years after gopher colonization, we found that gophers were active in similar to 2.5 % of the study area and formed similar to 328 mounds ha(-1). Mounds exhibited decreased species density compared to undisturbed areas, while plant abundance on mound margins increased 77 %. Plant burial increased total soil carbon (TC) by 13 % and nitrogen (TN) by 11 %, compared to undisturbed soils. Mound crusts decreased water infiltration, likely explaining the lack of detectable increases in rates of NO3-N, NH4-N or PO4-P leaching out of the rooting zone or in CO2 flux rates. We concluded that plant burial and reduced infiltration on gopher mounds may accelerate soil carbon accumulation, facilitate vegetation development at mound edges through resource concentration and competitive release, and increase small-scale heterogeneity of soils and communities across substantial sections of the primary successional landscape. Our review indicated that increases in TC, TN and plant density at mound margins contrasted with later successional systems, likely due to differences in physical effects and microbial resources between primary successional and older systems.

TI 18S rRNA gene sequencing identifies a novel species of Henneguya parasitizing the gills of the channel catfish (Ictaluridae) SO PARASITOLOGY RESEARCH LA English DT Article DE Myxozoa; Henneguya; Catfish; Ictalurus punctatus ID BLUE CATFISH; DNA-SEQUENCE; MYXOSPOREA; MYXOZOA; MYXOBOLIDAE; DISEASE; MORPHOLOGY; THELOHAN; HOST AB In the southeastern USA, the channel catfish Ictalurus punctatus is a host to at least eight different species of myxozoan parasites belonging to the genus Henneguya, four of which have been characterized molecularly using sequencing of the small subunit ribosomal RNA (SSU rRNA) gene. However, only two of these have confirmed life cycles that involve the oligochaete Dero digitata as the definitive host. During a health screening of farm-raised channel catfish, several fish presented with deformed primary lamellae. Lamellae harbored large, nodular, white pseudocysts 1.25 mm in diameter, and upon rupturing, these pseudocysts released Henneguya myxospores, with a typical lanceolate-shaped spore body, measuring 17.1+/-1.0 mu m (mean+/-SD; range=15.0-19.3 mu m) in length and 4.8+/-0.4 mu m (3.7-5.6 mu m) in width. Pyriform-shaped polar capsules were 5.8+/-0.3 mu m in length (5.1-6.4 mu m) and 1.7+/-0.1 mu m (1.4-1.9 mu m) in width. The two caudal processeswere 40.0+/-5.1 mu m in length (29.5-50.0 mu m) with a spore length of 57.2+/-4.7 (46.8-66.8 mu m). The contiguous SSU rRNA gene sequence obtained from myxospores of five excised cysts did not match any Henneguya sp. in GenBank. The greatest sequence homology (91 % over 1,900 bp) was with Henneguya pellis, associated with blister-like lesions on the skin of blue catfish Ictalurus furcatus. Based on the unique combination of pseudocyst and myxospore morphology, tissue location, host, and SSU rRNA gene sequence data, we report this isolate to be a previously unreported species, Henneguya bulbosus sp. nov.

Moreover, it is suggested that flying insects will also modulate their flight speed to maintain a constant retinal angular velocity of terrestrial contrast elements. Evidence from flies and honeybees supports such a hypothesis, although tests with male moths and beetles flying in pheromone plumes are not conclusive. These insects typically fly faster at higher elevations above a high-contrast ground pattern, as predicted by the hypothesis, although the increase in speed is not sufficient to demonstrate quantitatively that they maintain constant visual angular velocity of the ground pattern. To test this hypothesis more rigorously, the flight speed of male oriental fruit moths (OFM) Grapholita molestaBusck (Lepidoptera: Tortricidae) flying in a sex pheromone plume in a laboratory wind tunnel is measured at various heights (5-40cm) above patterns of different spatial wavelength (1.8-90 degrees) in the direction of flight. The OFM modulate their flight speed three-fold over different patterns. They fly fastest when there is no pattern in the tunnel or the contrast elements are too narrow to resolve. When the spatial wavelength of the pattern is sufficiently wide to resolve, moths fly at a speed that tends to maintain a visual contrast frequency of 3.5 +/- 3.2Hz rather than a constant angular velocity, which varies from 57 to 611 degrees s(-1). In addition, for the first time, it is also demonstrated that the width of a contrast pattern perpendicular to the flight direction modulates flight speed. C1 [Kuenen, Lodewyk P.

TI Identification of the Infection Route of a Fusarium Seed Pathogen into Nondormant Bromus tectorum Seeds SO PHYTOPATHOLOGY LA English DT Article ID PYRENOPHORA-SEMENIPERDA; PENETRATION; TURGOR; FUNGISTASIS; MORTALITY; OXYSPORUM; ADHESION; BIOLOGY; GROWTH; PLANTS AB The genus Fusarium has a wide host range and causes many different forms of plant disease. These include seed rot and seedling blight diseases of cultivated plants. The diseases caused by Fusarium on wild plants are less well-known. In this study, we examined disease development caused by Fusarium sp. n on nondormant seeds of the important rangeland weed Bromus tectorum as part of broader studies of the phenomenon of stand failure or "die-off" in this annual grass. We previously isolated an undescribed species in the F. tricinctum species complex from die-off soils and showed that it is pathogenic on seeds. It can cause high mortality of nondormant B. tectorum seeds, especially under conditions of water stress, but rarely attacks dormant seeds. In this study, we used scanning electron microscopy (SEM) to investigate the mode of attack used by this pathogen. Nondormant B. tectorum seeds (i.e., florets containing caryopses) were inoculated with isolate Skull C1 macroconidia. Seeds were then exposed to water stress conditions (-1.5 MPa) for 7 days and then transferred to free water. Time lapse SEM photographs of healthy versus infected seeds revealed that hyphae under water stress conditions grew toward and culminated their attack at the abscission layer of the floret attachment scar. A prominent infection cushion, apparent macroscopically as a white tuft of mycelium at the radicle end of the seed, developed within 48 h after inoculation. Seeds that lacked an infection cushion completed germination upon transfer to free water, whereas seeds with an infection cushion were almost always killed. In addition, hyphae on seeds that did not initiate germination lacked directional growth and did not develop the infection cushion. This strongly suggests that the fungal attack is triggered by seed exudates released through the floret attachment scar at the initiation of germination. Images of cross sections of infected seeds showed that the fungal hyphae first penetrated the caryposis wall, then entered the embryo, and later ramified throughout the endosperm, completely destroying the seed.

TI Coupling Spore Traps and Quantitative PCR Assays for Detection of the Downy Mildew Pathogens of Spinach (Peronospora effusa) and Beet (P. schachtii) SO PHYTOPATHOLOGY LA English DT Article ID POLYMERASE-CHAIN-REACTION; BOTRYTIS LEAF-BLIGHT; AIRBORNE INOCULUM; PHYLOGENETIC-RELATIONSHIPS; LEPTOSPHAERIA-MACULANS; POOLED DNA; QUANTIFICATION; FARINOSA; DISEASE; CHENOPODIUM AB Downy mildew of spinach (Spinacia oleracea), caused by Peronospora effusa, is a production constraint on production worldwide, including in California, where the majority of U. S. spinach is grown. The aim of this study was to develop a real-time quantitative polymerase chain reaction (qPCR) assay for detection of airborne inoculum of P. effusa in California. Among oomycete ribosomal DNA (rDNA) sequences examined for assay development, the highest nucleotide sequence identity was observed between rDNA sequences of P. effusa and P. schachtii, the cause of downy mildew on sugar beet and Swiss chard in the leaf beet group (Beta vulgaris subsp. vulgaris). Single-nucleotide polymorphisms were detected between P. effusa and P. schachtii in the 18S rDNA regions for design of P. effusa-and P. schachtii-specific TaqMan probes and reverse primers. An allele-specific probe and primer amplification method was applied to determine the frequency of both P. effusa and P. schachtii rDNA target sequences in pooled DNA samples, enabling quantification of rDNA of P. effusa from impaction spore trap samples collected from spinach production fields. The rDNA copy numbers of P. effusa were, on average, approximate to 3,300-fold higher from trap samples collected near an infected field compared with those levels recorded at a site without a nearby spinach field. In combination with disease-conducive weather forecasting, application of the assays may be helpful to time fungicide applications for disease management.

Planting resistant varieties and changing cultural practices has dramatically reduced virus impact in subsequent decades. Current information on the distribution, diversity, and impact of known and potential U.S. maize disease-causing viruses is lacking. To assess the current reservoir of viruses present at the sites of past disease emergence, we used a combination of serological testing and next-generation RNA sequencing approaches. Here, we report enzyme-linked immunosorbent assay and RNA-Seq data from samples collected over 2 years to assess the presence of viruses in cultivated maize and an important weedy reservoir, Johnsongrass (Sorghum halepense). Results revealed a persistent reservoir of MDMV and two strains of MCDV in Ohio Johnsongrass. We identified sequences of several other grass-infecting viruses and confirmed the presence of Wheat mosaic virus in Ohio maize. Together, these results provide important data for managing virus disease in field corn and sweet corn maize crops, and identifying potential future virus threats. C1 [Stewart, L. R.; Todd, J.

However, we lack a comparative assessment of the available methods. Here, we test how: i) four commonly used methods to leach plant litter, ii) cutting of the litter, and iii) litter species affect the quantity and composition of dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) leached using fourier transform mid-infrared spectroscopy (FTIR). Methods We tested how soaking litter in water, dripping water over litter, and shaking litter in two different volumes of water affected leaching of both cut and whole leaves of alfalfa (Medicago sativa), ash (Fraxinus excelsior), big bluestem grass (Andropogon gerardii), oak (Quercus macrocarpa) and pine (Pinus ponderosa) litter. We measured DOC and TDN on the leachate to quantify how much DOM was leached by each method. We used the DOC: TDN ratio and FTIR to analyze the composition of the DOM leached. Results The leaching method and cutting had an impact on the amount of DOM leached from the litter. The amount of DOM leached was also affected by the litter species and its interaction with leaching method and cutting. FTIR analysis identified the same main functional groups of plant litter leachates across all of the litter species. Leaching method, cutting and litter type affected the concentration of the leachate and the resolution of the FTIR spectral data but not the relative contribution of the main functional groups. Conclusions Methods of leaching should be chosen consistently with experimental objectives and type of litter examined. The leaching method, cutting of the litter and litter species should be taken into consideration when comparing data on DOM amounts obtained from different leaching methods but the leachate consists of similar functional group components across method, cutting and litter species.

While rising atmospheric [CO2] is a driving force behind the warmer temperatures and drought, which aggravate fungal disease and mycotoxin accumulation, our understanding of how elevated [CO2] will effect maize defences against such pathogens is limited. Here we report that elevated [CO2] increases maize susceptibility to Fusarium verticillioides proliferation, while mycotoxin levels are unaltered. Fumonisin production is not proportional to the increase in F.verticillioides biomass, and the amount of fumonisin produced per unit pathogen is reduced at elevated [CO2]. Following F.verticillioides stalk inoculation, the accumulation of sugars, free fatty acids, lipoxygenase (LOX) transcripts, phytohormones and downstream phytoalexins is dampened in maize grown at elevated [CO2]. The attenuation of maize 13-LOXs and jasmonic acid production correlates with reduced terpenoid phytoalexins and increased susceptibility. Furthermore, the attenuated induction of 9-LOXs, which have been suggested to stimulate mycotoxin biosynthesis, is consistent with reduced fumonisin per unit fungal biomass at elevated [CO2]. Our findings suggest that elevated [CO2] will compromise maize LOX-dependent signalling, which will influence the interactions between maize and mycotoxigenic fungi. Elevated [CO2] increases maize susceptibility to Fusarium verticillioides proliferation but mycotoxin levels are unaltered. The attenuation of maize 13-LOXs and JA production correlates with reduced terpenoid phytoalexins and increased susceptibility. Furthermore, the attenuated induction of 9-LOXs, which have been suggested to stimulate mycotoxin biosynthesis, is consistent with reduced fumonisin per unit fungal biomass at elevated [CO2].

This study examined the seroprevalence and associated risk factors for infection with Toxoplasma gondii in 379 sheep from 12 flocks in Rio de Janeiro state, Brazil. Using the modified agglutination test (MAT), 202 (53.3 %) of 379 were seropositive with titers of 1:25 in 65, 1:50 in 40, 1:100 in 23, 1:200 in 11, 1:400 in 36, 1:800 in 7, 1:1,600 in 1, and 1:3,200 or higher in 19 sheep. The most significant factors associated with T. gondii seropositivity in sheep were age, gender, and veterinary care. Finding of T. gondii antibodies in 97 of the 202 sheep in titers of 1:100 or higher is indicative of persistently infected animals. This high level of seropositivity requires urgent control measures to reduce impact on animal productivity and public health.

Little is known of Toxoplasma gondii infection in alpacas worldwide. In the present study, T. gondii was isolated and genetically characterized from alpacas for the first time. Alpacas (n = 16) and rams (n = 12) pastured on a farm in Virginia, USA, were examined at necropsy. Antibodies to T. gondii were determined by the modified agglutination test (MAT, 1:25) and found in 6 of 16 alpacas with titers of 1:100 (2 alpaca), 1:400 (2 alpacas), 1:800 (1 alpaca), and 1:1,600 (1 alpaca), and 5 of 12 rams in titers of 1:50 in one, 1:400 in one, 1:800 in one, 1:1,600 in one, and 1:3,200 in one. Tissues of all 16 alpacas were bioassayed in mice or in cats. Muscles (heart, skeletal muscle) of nine alpacas with MAT titers of 1:25 were fed to T. gondii-free cats; the cats did not shed oocysts. Viable T. gondii was isolated from tissues of two of six seropositive alpacas by bioassay in mice. Viable T. gondii was isolated from three of three seropositive sheep by bioassay in mice. Genotyping using cell-cultured tachyzoites revealed four genotypes, including one for ToxoDB PCR-RFLP genotype #2 (type III), one for genotype #3 (type II variant), one for genotype #170, and two for a new genotype designated as ToxoDB PCR-RFLP genotype #230. Thus, four of the five T. gondii isolates in the present study belonged to different genotypes. These results indicate a higher genetic diversity among T. gondii isolates circulating in the USA than previously realized.

We conducted a study to determine if woody plant species composition and abundance along headwater streams were correlated with categorical and continuous LULC and environmental variables along an urban-to-rural gradient. These variables were calculated at different spatial scales (subcatchment level and within 0.5 and 1 km radii of plots) and used % impervious surface cover (ISC) and finer scale LULC classification levels to determine their ability to explain species composition, diversity, abundance, non-native provenance and wetland indicator status of four plant strata-canopy tree, tree sapling, tree seedling and shrub. At all scales, we found distinct riparian woody communities within land-use categories, with significant differences among shrub species. Fine-scale land-cover variables correlated with species composition of shrub, tree sapling and tree seedling strata, but not the canopy tree stratum. Celtis occidentalis and Acer negundo were ubiquitous but dominated riparian areas surrounded by development, while Asimina triloba was associated with forested rural riparian banks. Non-native shrubs, Lonicera maackii and Euonymus alatus, were indicative of areas surrounded by development, while the native shrub, Lindera benzoin, was associated with deciduous forest. Negative factor-ceiling relationships between canopy tree, sapling and tree seedling densities and % ISC were found, with abrupt declines above approximately 30 % ISC. Facultative wetland shrubs were not found above 30 % ISC. Streambank height, which was strongly negatively correlated with depth to the water table and positively correlated with cumulative catchment area, was negatively correlated with facultative wetland tree and shrub species. In addition, riparian tree sapling and seedling densities declined as the abundance of Lonicera maackii increased. C1 [White, R.

SO WORLDS POULTRY SCIENCE JOURNAL LA English DT Article DE turkey; exchange rate volatility; gravity model; international trade ID RATE UNCERTAINTY; INTERNATIONAL-TRADE; AGRICULTURAL TRADE; GRAVITY EQUATION; VEGETABLE TRADE; COMPETITION; EXPORTS AB A gravity model was used to determine the impact of exchange rate volatility on turkey trade flows. Previous analyses of aggregate agricultural sectors or products have assumed the effect of exchange rate volatility is uniform, that is, it impacts the individual components of the aggregates in the same way. This is highly unlikely, given the differences in biological and marketing factors across commodities and sectors. In order to address this issue, we examined how exchange rate volatility affects international turkey trade rather than the more commonly analysed 'poultry' trade. Findings revealed that the effects of short- and long-run exchange rate volatility on bilateral turkey trade are positive and statistically significant. Increasing distance between importing and exporting countries has a negative effect on turkey trade flows, while being a member of NAFTA and EU-27 has positive impacts on those flows.

To better understand the genetic diversity of this virus, the complete genome of an isolate from Washington State (WA), USA, was characterized. Sequence comparisons of the WA isolate with other known sequences revealed that the RNA-Rep-encoded RdRp protein and the RNA-CP-encoded coat protein displayed > 99 % amino acid sequence identity to those of two Nordic (RdRp) and several European and North American isolates (CP), respectively. The RNA-TGB-encoded TGB 1 and TGB 3 protein sequences had > 99 % amino acid sequence identity to the corresponding proteins of Czech and Danish isolates, whereas the TGB 2 protein is identical to those of Colombian isolates. Phylogenetic analysis of the viral genes of the WA isolate reflected the close relationship between WA and European isolates. RFLP analysis of corresponding DNA of RNA TGB and RNA CP revealed that the WA isolate has the RNA TGB-II and RNA CP-B types, which are prevalent in Europe and other parts of world. This is the first report of the complete genome characterization of PMTV from the Americas. C1 [Ramesh, S. V.; Raikhy, G.; Pappu, H.

With a small circular RNA genome of about 250-400 nt, which apparently does not code for any protein, viroids replicate and move systemically in host plants. Since the discovery of the first viroid almost forty-five years ago, many different viroids have been isolated, characterized and, frequently, identified as the causal agents of plant diseases. The first viroid classification scheme was proposed in the early 1990s and adopted by the International Committee on Taxonomy of Viruses (ICTV) a few years later. Here, the current viroid taxonomy scheme and the criteria for viroid species demarcation are discussed, highlighting the main taxonomic questions currently under consideration by the ICTV Viroid Study Group. The impact of correct taxonomic annotation of viroid sequence variants is also addressed, taking into consideration the increasing application of next-generation sequencing and bioinformatics for known and previously unrecognized viroids.

TI Patterns of parasitoid host utilization and development across a range of temperatures: implications for biological control of an invasive forest pest SO BIOCONTROL LA English DT Article DE Egg parasitoid; Forest pest; Climatic change; Invasive; Agrilus planipennis ID EMERALD ASH BORER; AGRILUS-PLANIPENNIS COLEOPTERA; CLIMATE-CHANGE; NORTH-AMERICA; HYMENOPTERA-BRACONIDAE; NATURAL ENEMIES; BUPRESTIDAE; CHINA; ENCYRTIDAE; RESPONSES AB Although climate change frequently has been linked to observed shifts in the distributions or phenologies of species, little is known about the potential effects of varying temperatures on parasitoids and their relationships with hosts. Using the egg parasitoid Oobius agrili (Hymenoptera: Encyrtidae) we examined host utilization patterns of this species across a range of temperatures (20-35 A degrees C) to explore how changing climate could affect the interaction with its host-the emerald ash borer (EAB) (Coleoptera: Buprestidae), a serious invasive forest pest that has killed tens of millions of ash (Fraxinus spp.) trees in North America. Results from our study showed that the window of host susceptibility to O. agrili parasitism declined significantly from 14.8 to 2.6 days in an inverse second-order relationship with increasing exposure temperatures from 20 to 35 A degrees C. In contrast, parasitoid host attack rate changed in a bell-shaped second-order relationship-i.e., increased with temperatures from 20 to 25 A degrees C, but decreased at about the same rate when temperatures increased from 30 to 35 A degrees C. This range of temperatures also significantly affected the development and mortality of immature parasitoids with 35 A degrees C resulting in 100 % mortality. There was little mortality (0-4.5 %) and no significant differences in the percentage (20.9-34.9 %) of immature O. agrili that entered diapause (as mature larvae) at 20, 25, and 30 A degrees C. However, there were significant differences in the time event of adult wasp emergence within this temperature range. The median time for 50 % of immature O. agrili emerging as adults at 20, 25, and 30 A degrees C were 38, 18, and 17 days after parental wasp oviposition, respectively. Together these findings indicate that the non-linear and unequal temperature effects on these host utilization parameters are likely to result in differential host parasitism rates, and thus could reduce the efficacy of this parasitoid in suppressing host populations due to climate change (global warming and extreme heat).

The egg parasitoid Oobius agrili Zhang and Huang (Hymenoptera: Encyrtidae) was introduced from China as a biological control agent for this pest in Michigan and throughout the infested area of the United States. A critical component of any biological control program is post-release monitoring and evaluation; however, because of the small size and cryptic nature of O. agrili, evaluation of its impact is difficult. We compared two methods for measuring parasitism of emerald ash borer eggs: (1) timed visual searches of bark on standing ash trees and (2) bark collection, sifting, and sorting. Both methods were carried out in paired parasitoid-release and control plots, the visual search method over a six-year period (2008-2013) and the more recently developed bark-collection and sifting method for 2 years (2012-2013). The visual search method found parasitism in release plots remained low (0.7-4.2%) in samples taken from 2008 to 2012 and reached 10.6% in 2013. In comparison, the bark-sifting method found that rates of egg parasitism were considerably higher in release plots, 21.8% and 18.9% for samples taken in 2012 and 2013, respectively. These findings indicate that the population-level impact of O. agrili is increasing and may be an important source of mortality for EAB populations. We recommend the bark-collection and sifting method as the more effective method to recover parasitoids and estimate parasitism rates of O. agrili. (C) 2014 Elsevier Inc. All rights reserved.

Fungicides have limited effectiveness, but there are concerns that they may only inhibit pathogen growth and hasten resistance development after repeated fungicide applications. Biological control is an active control measure that can work continuously as long as the agent is alive and active. The goal of this study was to examine whether Trichoderma spp. have the potential as a biological control agent against P. ramorum. Sixteen Trichoderma spp. isolates were screened for mycoparasitism of P. ramorum in a dual culture assay. The different Trichoderma spp. isolates demonstrated variable mycoparasitic activities with some isolates showing no activity while others completely eliminated the pathogen after 4 weeks. Seven isolates of T. asperellum were consistent among replicated trials in eliminating recovery of P. ramorum from the exposed agar plugs and preventing leaf disk necrosis. Further testing of six T. asperellum isolates against two different P. ramorum isolates (A1 and A2 mating types) resulted in the same high level of mycoparasitic activity. Soil assays involving P. ramorum-infested potting mix and selected Trichoderma spp. isolates demonstrated that two isolates (04-22 and 02-64) were consistent among the repetitions to eliminate P. ramorum propagules to non-detectable levels. Based on these results, specific T. asperellum isolates have the potential to remediate P. ramorum-infested soil and have the potential to be developed into a commercially-viable product.

However, little is known about their host-location behaviors. We evaluated responses to their host complex, Fraxinus pennsylvanica stem tissue, F. pennsylvanica foliage, and an A. planipennis larva within a stem. Experiments were conducted in a Y-tube olfactometer, using wasps reared on A. planipennis larvae in F. pennsylvanica stems. Naive S. agrili were attracted to the entire complex, and to leaf tissue, relative to blanks. S. agrili were also more attracted to stems containing larvae and leaf tissue together than leaf tissue alone. Naive S. floridanus were attracted to larvae within stems, but nothing else. A further distinction is that S. agrilli moved more, in the presence of foliage. Thus, S. agrili and S. floridanus appear to employ different host-location strategies. The former is attracted to host plant cues, which then elicit increased searching, whereas the latter is only attracted to infested tissue directly. We found no evidence that oviposition influences attraction by S. agrili, suggesting other forms of experience should be evaluated for potential sources of learned cues. Further, S. agrili that declined opportunities to oviposit oriented away from host-associated cues, suggesting distinct behavioral sequences occur by females that are not reproductively ready. Further understanding of host-location behavior may improve biological control by these parasitoids, by suggesting strategies for pre-release conditioning and providing tools for assessing post-release establishment.

Emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), introduced into the U.S. from Asia in the late twentieth century, has caused widespread mortality, primarily in green ash, Fraxinus pennsylvanica Marsh. (Section: Melioides) and now impacts other North American ash species. The development and successful reintroduction of resistant trees requires genetic tools to evaluate population dynamics and aid in species identification. Here, we report 15 novel EST-SSR markers developed in green ash, most of which amplify and are polymorphic across 18 species of Fraxinus, including six species native to North America. The high average polymorphism information content (0.741) and allelic richness (15.3) revealed in six disparate populations of green ash indicate that these markers also have utility for investigating population dynamics in this species.

Infection by the bacterial endosymbiont Hamiltonella defensa is capable of protecting the pea aphid from parasitism by Aphidius ervi and the black bean aphid from parasitism by Lysiphlebus fabarum. Here we investigate protection of a third aphid species, the cowpea aphid, Aphis craccivora, from four parasitoid species: Binodoxys communis, B. koreanus, Lysiphlebus orientalis, and Aphidius colemani. 2. We compared parasitism of A. craccivora lines that were either infected with, or cured of H. defensa separately for the four parasitoid species. Infection by H. defensa almost completely eliminated parasitism of A. craccivora by B. communis and B. koreanus, but had no effect on parasitism by L. orientalis and A. colemani. 3. This indicates at least genus-level specificity of protective effects by H. defensa and we discuss implications of our findings on the known world-wide distribution of this host/symbiont interaction.

Mineral sources occur as natural geological deposits (i.e., licks) or as anthropogenic mineral supplements. In both scenarios, these sources commonly serve as focal sites for visitation. We monitored 11 licks in Rocky Mountain National Park, north-central Colorado, using trail cameras to quantify daily visitation indices (DVI) and soil consumption indices (SCI) for Rocky Mountain elk (Cervus elaphus) and mule deer (Odocoileus hemionus) during summer 2006 and documented elk, mule deer, and moose (Alces alces) visiting licks. Additionally, soil samples were collected, and mineral concentrations were compared to discern levels that explain rates of visitation. Relationships between response variables; DVI and SCI, and explanatory variables; elevation class, moisture class, period of study, and concentrations of minerals were examined. We found that DVI and SCI were greatest at two wet, low-elevation licks exhibiting relatively high concentrations of manganese and sodium. Because cervids are known to seek Na from soils, we suggest our observed association of Mn with DVI and SCI was a likely consequence of deer and elk seeking supplemental dietary Na. Additionally, highly utilized licks such as these provide an area of concentrated cervid occupation and interaction, thus increasing risk for environmental transmission of infectious pathogens such as chronic wasting disease, which has been shown to be shed in the saliva, urine, and feces of infected cervids.

Multilocus sequence analysis was used to compare Ethiopian strains with representative Xanthomonas strains from a worldwide collection based on DNA sequences of six housekeeping genes (lacF, lepA, gyrB, fusA, gltA and gapA) and hrpB genes. Phylogenetic analysis of the concatenated sequences showed that X. gardneri, X. vesicatoria and X. perforans were associated with BST in Ethiopia, whereas Xanthomonas euvesicatoria was absent from the Ethiopian sample. There was no genetic diversity among the isolated strains belonging to X. gardneri and X. perforans. However, two X. vesicatoria haplotypes were identified indicating at least two different sources of introduction of X. vesicatoria to Ethiopia. All of the X. perforans strains were only pathogenic on tomato and were T3 strains with the exception of one identified as tomato race 4 (T4). The X. gardneri and X. vesicatoria strains were tomato race 2 (T2), but were variable in pepper race determinations indicating variation in effectors among strains.

Here, we measured the effectiveness of glass wool filters to simultaneously concentrate enteric viruses and bacteria of bovine origin from water. The recovery efficiencies were determined for bovine viral diarrhea virus types 1 and 2, bovine rotavirus group A, bovine coronavirus, poliovirus Sabin III, toxigenic Escherichia coli ,and Campylobacter jejuni seeded into water with three different turbidity levels (0.5, 215, and 447 NTU). Twenty liters of dechlorinated tap water (pH 7) were seeded with the test organisms, and then passed through a glass wool filter using a peristaltic pump (flow rate = 1 liter min(-1)). Retained organisms were eluted from the filters by passing beef extract-glycine buffer (pH 9.5) in the direction opposite of sample flow. Recovered organisms were enumerated by qPCR except for C. jejuni, which was quantified by culture. Mean recovery efficiencies ranged from 55 to 33 % for the bacteria and 58 to 16 % for the viruses. Using bootstrapping techniques combined with Analysis of Variance, recovery efficiencies were found to differ among the pathogen types tested at the two lowest turbidity levels; however, for a given pathogen type turbidity did not affect recovery except for C. jejuni. Glass wool filtration is a cost-effective method for concentrating several waterborne pathogens of bovine origin simultaneously, although recovery may be low for some specific taxa such as bovine viral diarrhea virus 1.

China has more plantations than any other country as a consequence of massive afforestation efforts. We use data from China to comparatively examine tree biomass and productivity of planted and natural stands in relation to climate zone, latitude, elevation, age and species diversity (richness). LocationSix forest climate/vegetation zones in China. MethodsWe used a database completed in 2007 and then updated in 2013 that contained extensive records of forest stands (10mx10m plots) across China. The database records included a total of 6153 forest stands (1716 planted forests aged 0-80 years and 4437 natural forests of aged 0-400 years), located from 18.1 to 53.2 degrees N and 75.53 to 131.8 degrees E, and between elevations of 7 and 4240m above sea level. These forests were grouped into six climate zones for comparisons. ResultsUnder generally similar physical conditions (climate zones) to those in natural forests and despite having low diversity (i.e. often a single tree species), plantations aged 0-80 years already had similar biomass but much higher productivity, and thus much higher carbon sequestration rates, than natural forests. Tree biomass, productivity and their above/below ground ratios showed stronger latitudinal and elevational trends in natural forests than in planted forests. No difference in productivity was observed between the planted forests with one or two species; in natural forests, however, high diversity usually led to high productivity. Main conclusionsThe differences in performance between planted and natural forests were mainly explained by: (1) age (the plantations were in early succession), (2) elevation (plantations were located at lower elevations), and (3) species selection (only highly productive species were planted). As the plantations were all still young, closer monitoring of their performance is needed. C1 [Guo, Qinfeng] USDA FS, Eastern Forest Environm Threat Assessment Ctr, Asheville, NC 28804 USA.

The analytes include: 13 sulfonamides, trimethoprim, 3 fluoroquinolones, 3 quinolones, 3 triphenylmethane dyes, 2 leuco dye metabolites, and 1 hormone. In this method, tissue is mixed with EDTA-Mcllvaine buffer, double-extracted with acetonitrile, p-toluenesulfonic (p-TSA) acid and N,N,N',N'-tetramethyl-p-phenylenediamine dihydrochloride (TMPD), and analyzed using LC-MS/MS. Inclusion of p-TSA and TMPD in the extraction procedure was critical for simultaneous analysis of dyes with the other groups of veterinary drugs. The proposed procedure was validated as both a quantitative analysis method and as a semi-quantitative screening method for multiple fish and shrimp matrices. The method was applied to eight types of fish (catfish, eel, pangasius, sablefish, tilapia, swai, salmon, and trout) and shrimp at the appropriate level of concern: 10 ng/g for sulfonamides, trimethoprim, and quinolones, 5 ng/g for fluoroquinolones, 1 ng/g for dyes and their metabolites, and 0.4 ng/g for methyltestosterone.

TI Visualizing surface area and volume of lumens in three dimensions using images from histological sections SO JOURNAL OF MICROSCOPY LA English DT Article DE 3-D reconstruction; histology; liver; negative space; portal tract AB Visualizing the interior (lumen) of a tubular structure within tissue can provide a unique perspective on anatomical organization of the tissue. Portal tracts of the liver contain several vessels and ducts in various patterns of intertwining branches and are an example of such spaces. An inexpensive method, using light microscopy and a sample of conventionally stained canine livers, was used to colorize and allow visualization of the lumens of vessels within the portal tract in three dimensions. When the colour of the background was digitally cleared and the lumen filled with a solid colour, it was possible to measure areas and volumes of the portal vein, arteries, bile ducts and lymphatics. Significant differences between vessels and ducts across lobes and gender in control samples are discussed. Differences were also found between control and mixed breed dogs and between controls and a dog that died of accidental traumatic haemorrhage. These differences are discussed in relation to visualizing lumens using images generated from a light microscope. Vessels in plants such as xylem and continuously formed spaces resulting from ice formation are other examples where this technique could be applied.

The case study of Beddingia siricidicola released for the management of Sirex noctilio SO JOURNAL OF PEST SCIENCE LA English DT Article DE Macroparasites; Forest insects; Biological control; Patagonia ID BIOLOGICAL-CONTROL; SOUTHERN-HEMISPHERE; WOODWASP; DELADENUS; NEOTYLENCHIDAE; HYMENOPTERA; PARASITISM; PATHOGENS; ECOLOGY AB Though rarely used in this way, biological control could potentially be exploited for managing spread of invasive species. Because spread of invasive species emerges from the combined action of population growth and dispersal, natural enemies that affect either of these processes should also affect spread. Dispersal of parasitoid species plays a key role in determining their impact on population growth of an invading host species along their expanding population front. In contrast, dispersal of most true parasites only occurs via movement of hosts so any impact that parasites may have on host dispersal may limit the parasite's own capacity to keep up with an expanding host population. We test this premise by examining field data from what is probably the best example of the successful use of true parasites in biological control: the nematode Beddingia (= Deladenus) siricidicola, which is released for management of Sirex noctilio populations. We analyze the historical impact of nematode releases on the rate of spread of invasive S. noctilio populations in Southern Argentina. Our findings suggest that, nematode releases did not discernibly slow the spread of S. noctilio populations. We conclude that although entomophagous parasites could be effective at reducing the growth and dispersal of localized host populations, they are unlikely, unless widely released through the leading edges, to slow the spread of invading hosts.

Since its introduction into Georgia in 2002, X. glabratus has spread throughout the southeastern U.S., and laurel wilt has decimated native Persea trees, particularly redbay (P. borbonia) and swampbay (P. palustris). The lethal disease now threatens avocado (P. americana) in Florida. To control the spread of laurel wilt, effective attractants are needed for early detection of the vector. Phoebe oil lures are the best known attractant, but they are no longer available. Current detection relies on manuka oil lures, but our previous research indicated they have a field life of only 2-3 weeks in Florida. Therefore, we evaluated seven essential oils as attractants for X. glabratus, and ethanol as a potential synergist. Field tests and electroantennography (EAG) were conducted to compare attraction and olfactory response to angelica seed, cubeb, ginger root, manuka, phoebe, tea tree, and orange oils. The highest captures were obtained with cubeb, manuka, and phoebe oils; ginger and angelica oils were intermediate, and tea tree and orange oils were not attractive. Addition of ethanol to oil lures did not increase captures. In subsequent tests with commercial formulations, cubeb lures captured more X. glabratus than manuka lures, were better for early detection at low population levels, and had longevity of at least 8 weeks. The highest EAG responses were elicited with phoebe and cubeb lures. Our results indicate that cubeb lures are the best attractant currently available for detection of X. glabratus.

A water quality index is constructed employing various contaminants which are then treated together with variables including organizational type as endogenous in an input distance function model. The cost of drinking water quality and inefficiency are derived and hypothesis tests estimated concerning their variation by location, organization type and water quality. The key findings are that more technically efficient water utilities deliver higher quality drinking water and that private firms distribute higher quality water at a higher price and at a higher implicit cost than public utilities despite no overall inefficiency differences between the two organizational types.

Second, we find that technology embodied in capital was an important source of productivity growth in agriculture.

HSV successfully entered DHCR24(-/-) cells, which lack a desmosterol-to-cholesterol conversion enzyme, indicating that entry can occur independently of cholesterol. Depletion of desmosterol from these cells resulted in diminished HSV-1 entry, suggesting a general sterol requirement for HSV-1 entry and that desmosterol can operate in virus entry. Cholesterol functioned more effectively than desmosterol, suggesting that the hydrocarbon tail of cholesterol influences viral entry.

Our aim was to analyse the diversity of gut-associated bacteria in wild-caught larvae and adult flesh flies using culture-dependent and culture-independent methods. Analysis of 16S rRNA gene sequences from cultured isolates and clone libraries revealed bacteria affiliated to Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes in the guts of larval and adult flesh flies. Bacteria cultured from larval and adult flesh fly guts belonged to the genera Acinetobacter, Bacillus, Budvicia, Citrobacter, Dermacoccus, Enterococcus, Ignatzschineria, Lysinibacillus, Myroides, Pasteurella, Proteus, Providencia and Staphylococcus. Phylogenetic analysis showed clone sequences of the genera Aeromonas, Bacillus, Bradyrhizobium, Citrobacter, Clostridium, Corynebacterium, Ignatzschineria, Klebsiella, Pantoea, Propionibacterium, Proteus, Providencia, Serratia, Sporosarcina, Weissella and Wohlfahrtiimonas. Species of clinically significant genera such as Ignatzschineria and Wohlfahrtiimonas spp. were detected in both larvae and adult flesh flies. Sequence analysis of 16S rRNA gene libraries supported culture-based results and revealed the presence of additional bacterial taxa. This study determined the diversity of gut microbiota in flesh flies, which will bolster the ability to assess microbiological risk associated with the presence of these flies. The present data thereby establish a platform for a much larger study. C1 [Gupta, A. K.; Sawant, S. S.; Bhonde, R. R.; Shouche, Y. S.] Natl Ctr Cell Sci, Mol Biol Unit, Pune, Maharashtra, India.

(Diptera: Muscidae) harbours and transmits a variety of human enteropathogens including Escherichia coli (Enterobacteriales: Enterobacteriaceae) O157:H7. Interactions between ingested bacteria and the fly gut directly impact bacterial persistence, survival and ultimately fly vector competence. We assessed the temporospatial fate of green fluorescent protein (GFP)-expressing E.coliO157:H7 (GFP-ECO157) in house flies along with fly antimicrobial responses up to 12h post-ingestion. In flies fed GFP-ECO157, culture and microscopy revealed a steady decrease in bacterial load over 12h, which is likely to be attributable to the combined effects of immobilization within the peritrophic matrix, lysis and peristaltic excretion. However, flies can putatively transmit this pathogen in excreta because intact bacteria were observed in the crop and rectum. Quantitative reverse-transcriptase polymerase chain reaction analysis of antimicrobial peptides (AMPs) and lysozyme gene expression showed minimal upregulation in both the gut and carcass of house flies fed GFP-ECO157. However, these genes were upregulated in fly heads and salivary glands, and effector proteins were detected in the gut in some flies. Collectively, these data indicate that house flies can serve as reservoirs of E.coliO157:H7 for up to 12h, and factors in addition to AMPs and lysozyme may contribute to bacteria destruction in the gut.

In the present study, we investigated age-dependent behavioral abnormalities in PrPC-knockout (Prnp0/0) mice and wildtype (WT) controls. Prnp0/0 mice showed age-dependent behavioral deficits in memory performance, associative learning, basal anxiety, and nest building behavior. Using a hypothesis-free quantitative proteomic investigation, we found that loss of PrPC affected the levels of neurofilament proteins in an age-dependent manner. In order to understand the biochemical basis of these observations, we analyzed the phosphorylation status of neurofilament heavy chain (NF-H). We found a reduction in NF-H phosphorylation in both Prnp0/0 mice and in PrPC-deficient cells. The expression of Fyn and phospho-Fyn, a potential regulator for NF phosphorylation, was associated with PrPC ablation. The number of beta-tubulin III-positive neurons in the hippocampus was diminished in Prnp0/0 mice relative to WT mice. These data indicate that PrPC plays an important role in cytoskeletal organization, brain function, and age-related neuroprotection. Our work represents the first direct biochemical link between these proteins and the observed behavioral phenotypes.

TI Manipulation of two alpha-endo-beta-1,4-glucanase genes, AtCel6 and GmCel7, reduces susceptibility to Heterodera glycines in soybean roots SO MOLECULAR PLANT PATHOLOGY LA English DT Article DE Arabidopsis; EGase; Heterodera glycines; Meloidogyne incognita; soybean ID PLANT-NEMATODE INTERACTIONS; CYST-NEMATODE; PARASITIC NEMATODE; KNOT NEMATODE; ARABIDOPSIS-THALIANA; RESISTANCE GENES; DEVELOPMENTAL EXPRESSION; UNITED-STATES; PROTEIN GENE; INFECTION AB Plant endo--1,4-glucanases (EGases) include cell wall-modifying enzymes that are involved in nematode-induced growth of syncytia (feeding structures) in nematode-infected roots. EGases in the - and -subfamilies contain signal peptides and are secreted, whereas those in the -subfamily have a membrane-anchoring domain and are not secreted. The Arabidopsis -EGase At1g48930, designated as AtCel6, is known to be down-regulated by beet cyst nematode (Heterodera schachtii) in Arabidopsis roots, whereas another -EGase, AtCel2, is up-regulated. Here, we report that the ectopic expression of AtCel6 in soybean roots reduces susceptibility to both soybean cyst nematode (SCN; Heterodera glycines) and root knot nematode (Meloidogyne incognita). Suppression of GmCel7, the soybean homologue of AtCel2, in soybean roots also reduces the susceptibility to SCN. In contrast, in studies on two -EGases, both ectopic expression of AtKOR2 in soybean roots and suppression of the soybean homologue of AtKOR3 had no significant effect on SCN parasitism. Our results suggest that secreted -EGases are likely to be more useful than membrane-bound -EGases in the development of an SCN-resistant soybean through gene manipulation. Furthermore, this study provides evidence that Arabidopsis shares molecular events of cyst nematode parasitism with soybean, and confirms the suitability of the Arabidopsis-H.schachtii interaction as a model for the soybean-H.glycines pathosystem.

TI EPSPS amplification in glyphosate-resistant spiny amaranth (Amaranthus spinosus): a case of gene transfer via interspecific hybridization from glyphosate-resistant Palmer amaranth (Amaranthus palmeri) SO PEST MANAGEMENT SCIENCE LA English DT Article DE Amaranthus spinosus; EPSPS; gene amplification; gene transfer; glyphosate; herbicide resistance; interspecific hybridization; introgression ID HERBICIDE RESISTANCE; FIELD CONDITIONS; TUBERCULATUS; RUDIS; MISSISSIPPI; MISSOURI; HYBRIDUS AB BACKGROUNDAmaranthus spinosus, a common weed of pastures, is a close relative of Amaranthus palmeri, a problematic agricultural weed with widespread glyphosate resistance. These two species have been known to hybridize, allowing for transfer of glyphosate resistance. Glyphosate-resistant A. spinosus was recently suspected in a cotton field in Mississippi. RESULTSGlyphosate-resistant A. spinosus biotypes exhibited a fivefold increase in resistance compared with a glyphosate-susceptible biotype. EPSPS was amplified 33-37 times and expressed 37 times more in glyphosate-resistant A. spinosus biotypes than in a susceptible biotype. The EPSPS sequence in resistant A. spinosus plants was identical to the EPSPS in glyphosate-resistant A. palmeri, but differed at 29 nucleotides from the EPSPS in susceptible A. spinosus plants. PCR analysis revealed similarities between the glyphosate-resistant A. palmeri amplicon and glyphosate-resistant A. spinosus. CONCLUSIONSGlyphosate resistance in A. spinosus is caused by amplification of the EPSPS gene. Evidence suggests that part of the EPSPS amplicon from resistant A. palmeri is present in glyphosate-resistant A. spinosus. This is likely due to a hybridization event between A. spinosus and glyphosate-resistant A. palmeri somewhere in the lineage of the glyphosate-resistant A. spinosus plants. Published 2014.

Wats.): hyperspectral reflectance properties of plants and potential for classification SO PEST MANAGEMENT SCIENCE LA English DT Article DE glyphosate-resistant weeds; herbicide-resistant weeds; hyperspectral imaging; Palmer amaranth; weed classification ID GENE AMPLIFICATION AB BACKGROUNDPalmer amaranth (Amaranthus palmeri S. Wats.) is a troublesome agronomic weed in the southern United States, and several populations have evolved resistance to glyphosate. This paper reports on spectral signatures of glyphosate-resistant (GR) and glyphosate-sensitive (GS) plants, and explores the potential of using hyperspectral sensors to distinguish GR from GS plants. RESULTSGS plants have higher light reflectance in the visible region and lower light reflectance in the infrared region of the spectrum compared with GR plants. The normalized reflectance spectrum of the GR and GS plants had best separability in the 400-500 nm, 650-690 nm, 730-740 nm and 800-900 nm spectral regions. Fourteen wavebands from within or near these four spectral regions provided a classification of unknown set of GR and GS plants, with a validation accuracy of 94% for greenhouse-grown plants and 96% for field-grown plants. CONCLUSIONSGR and GS Palmer amaranth plants have unique hyperspectral reflectance properties, and there are four distinct regions of the spectrum that can separate the GR from GS plants. These results demonstrate that hyperspectral imaging has potential application to distinguish GR from GS Palmer amaranth plants (without a glyphosate treatment), with future implications for glyphosate resistance management.

The aim was to determine optimal inoculation methods to evaluate the disease incidence using flower cushions in the field. A segregating mapping population of 580 trees (cultivar TSH 1188xCCN 51) was analysed under two field conditions: high and low inoculum levels (in different years), corresponding respectively to trees with or without dried witches' brooms hanging on the trees and producing basidiocarps. The number of newly formed cushion brooms in each tree was counted by the conventional method, and also the healthy and infected flower cushions in three 30cm-long regions along the trunk and the two main branches. The field inoculation methods discriminated between genotypes, with a 26% increase in disease incidence by Moniliophthora perniciosa at high inoculum. Two different segregation patterns were also observed: 27:27:9:1 under low, and 27:9:9:9:3:3:3:1 under high inoculum potential. It was also determined that at least 20 flower cushions were needed to accurately determine the percentage of infection. These methodologies allowed identification of the extreme phenotypes in this mapping population, and can therefore facilitate the detection of sources of resistance to witches' broom disease.

TI The nutrient density approach to healthy eating: challenges and opportunities SO PUBLIC HEALTH NUTRITION LA English DT Editorial Material DE Nutrient density; Healthy eating; Dietary Guidelines for Americans ID RICH FOODS; CARDIOVASCULAR-DISEASE; NUTRITIONAL QUALITY; CEREAL CONSUMPTION; NATIONAL-HEALTH; SATURATED FAT; INDEX; CHILDREN; DIETS; MILK AB The term 'nutrient density' for foods/beverages has been used loosely to promote the Dietary Guidelines for Americans. The 2010 Dietary Guidelines for Americans defined 'all vegetables, fruits, whole grains, fat-free or low-fat milk and milk products, seafood, lean meats and poultry, eggs, beans and peas (legumes), and nuts and seeds that are prepared without added solid fats, added sugars, and sodium' as nutrient dense. The 2010 Dietary Guidelines for Americans further states that nutrient-dense foods and beverages provide vitamins, minerals and other substances that may have positive health effects with relatively few (kilo) calories or kilojoules. Finally, the definition states nutrients and other beneficial substances have not been 'diluted' by the addition of energy from added solid fats, added sugars or by the solid fats naturally present in the food. However, the Dietary Guidelines Advisory Committee and other scientists have failed to clearly define 'nutrient density' or to provide criteria or indices that specify cut-offs for foods that are nutrient dense. Today, 'nutrient density' is a ubiquitous term used in the scientific literature, policy documents, marketing strategies and consumer messaging. However, the term remains ambiguous without a definitive or universal definition. Classifying or ranking foods according to their nutritional content is known as nutrient profiling. The goal of the present commentary is to address the research gaps that still exist before there can be a consensus on how best to define nutrient density, highlight the situation in the USA and relate this to wider, international efforts in nutrient profiling.

TI Epidemiological Analysis, Serological Prevalence and Genotypic Analysis of Foot-and-Mouth Disease in Nigeria 2008-2009 SO TRANSBOUNDARY AND EMERGING DISEASES LA English DT Article DE FMD; genotype; epidemiology; serology; West Africa; Nigeria ID LINKED-IMMUNOSORBENT-ASSAY; MOLECULAR EPIDEMIOLOGY; NUCLEOTIDE-SEQUENCE; VIRUS; AFRICA; POLYMERASE; DIAGNOSIS; ANTIBODY; WEST AB The epidemiological situation of foot-and-mouth disease virus (FMDV) is uncertain in Nigeria, where the disease is endemic, and the majority of outbreaks are unreported. Control measures for FMD in Nigeria are not being implemented due to the absence of locally produced vaccines and an official ban on vaccine importation. This study summarizes the findings of a 3-year study aimed at quantifying the seroprevalence of FMD, its distribution in susceptible species and the genetic diversity of FMDV isolated from the Plateau State of Nigeria. A 29% FMD prevalence was estimated using 3ABC enzyme-linked immunosorbent assay (3ABC ELISA). Farms with suspected FMD nearby, with contact with wildlife, that used drugs or FMD vaccines or with >100 animals, and animals of large ruminant species and in pastures other than nomadic grazing were significantly (P < 0.05) associated with FMD. Antibodies against five FMDV serotypes, (A, O, SAT1, SAT2 and SAT3) were detected by the virus neutralization test (VNT) at various titres (< 100-> 800) from all tested sera from most parts of the region. This is probably the first report of the presence of FMDV SAT3 in Nigeria. Further studies to investigate the potential probable presence and prevalence of SAT 3 virus in Nigeria are required. Tissue samples collected from clinical animals were positive for FMDV. Virus isolates were sequenced and confirmed as serotype A. All of the isolates showed marked genetic homogeneity with >99% genetic identity in the VP1 region and were most closely related to a previously described virus collected from Cameroon in 2000. This study provides knowledge on the epidemiological situation of FMD in Plateau State, Nigeria, and will probably help to develop effective control and preventive strategies for the disease in Nigeria and other countries in the West African subregion.

After approximately 3 weeks in tissue culture, fungi began budding out of cells obtained from the choroid plexus. After an additional 3 weeks, budding was observed in kidney cell cultures and eventually in monocyte cultures as well. Serum from the lamb was submitted to the Veterinary Diagnostic Laboratory at Colorado State University for fungal diagnosis and was found negative for Aspergillus, Blastomyces, Coccidioidomycosis and Histoplasmosis. DNA was isolated from fungi collected from tissue culture supernatants and used in a set of pan-fungal PCR assays with DNA from Candida acting as a positive control. PCR products were sequenced and BLAST analysis performed. The unknown fungal sequence aligned with 100% identity to Rhodotorula minuta an emerging opportunistic pathogen. Samples were submitted to The Fungal Testing Laboratory at The University of Texas Health Science Center at San Antonio for additional validation. We believe this to be the first report of Rhodotorula fungemia in a sheep in the United States. C1 [Chitko-McKown, C. G.; Leymaster, K. A.; Heaton, M. P.; Jones, S. A.; Clawson, M.

Little information is available regarding the carbon (C) functional groups carried away in wind eroded sediments away from the source soil. Mid-infrared (MidIR) spectroscopy was used on wind tunnel-blown sediments eroded from a loam soil during the fallow period of different cropping systems and tillage managements in Akron, Colorado. The soil was managed as fallow-winter wheat (Triticum aestivum L.) under conventional tillage (F-Wct) or no tillage (F-Wnt) and fallow-wheat-corn under no tillage (F-W-Cnt). Two wind eroded sediments were evaluated: fine dust (<35 mu m mean dia.) and saltation-size material (<175 mu m mean dia.). Our study showed that there is a partition of C groups within wind eroded sediments of different sizes and that they can reflect the tillage management history of soil. The fine dust had higher levels of aliphatic CH (2930 cm(-1)), and clays (3690-3620 cm(-1)). The saltation-sized material showed higher absorbance for quartz from 2000-1800 cm(-1) and reduced absorbance from 1250-1050 cm(-1). Both wind eroded sediments showed higher absorbance for -OH/NH groups and aliphatic CH from no-till soil. Finer dust sediments, which travel greater distances from the source soil than saltation size material, can carry away higher levels of aliphatic-carbon compounds and clays with potential negative impacts on SOM quantity and quality, and consequently the sustainability of these agroecosystems.

Erosion is initiated when the friction velocity exceeds the threshold friction velocity (u(*t)) of soils. Although u(*t) is influenced by soil physical properties such as wetness and crusting, there is little information available on the effect of soil crusting on u(*t). Knowledge of the relationship between soil crusting and u(*t) is required to improve our ability to predict wind erosion and PM10 (particulates <= 10 mu m in aerodynamic diameter) emissions from crusted soils. Threshold friction velocity was assessed on five soil types commonly found across the Columbia Plateau. These soils were obtained from agricultural fields, placed in trays, subject to various rainfall amounts to promote crust formation, and then exposed to winds inside a wind tunnel. Emission of soil particulates and PM10 as a function of wind speed were monitored by saltation and aerosol sensors. Threshold friction velocity was determined by systematically increasing wind speed until we observed an increase in airborne particulate or PM10 concentration. Threshold friction velocity increased with the development of a soil crust; u(*t) increased exponentially with an increase in crust strength and thickness. The relationship between u(*t) and crust thickness was influenced by clay content. The relationship between u(*t) and crust strength and thickness should be considered when simulating wind erosion of agricultural soils. Published by Elsevier B.V. C1 [Sharratt, B.

TI Consistency of wind erosion assessments across land use and land cover types: A critical analysis SO AEOLIAN RESEARCH LA English DT Article DE Wind erosion modeling; Model comparison; Horizontal mass flux; WEPS; SWEEP; RWEQ ID ATMOSPHERIC DUST CYCLE; COLUMBIA PLATEAU; DESERT GRASSLAND; SOIL; MODEL; PREDICTION; WEPS; VALIDATION; VEGETATION; TRANSPORT AB In recent decades, large areas of rangeland have been converted to cropland or vice versa in the western United States and elsewhere in the world, driven largely by increased crop prices, loss of access to irrigation water, and agricultural expansion/contraction. Wind erosion and dust emissions are key processes that have not been well studied during land use and associated land cover changes. This assessment is challenging because currently no model is available that can provide field-to landscape-scale estimates of wind erosion on both rangeland and cropland, and account for soil, vegetation and management changes. In this paper, we compare aeolian sediment transport estimates from available cropland models and a number of mass flux equations developed for rangelands, for a bare soil surface with different levels of crust and surface roughness under different wind speeds. Our results show that the simulated horizontal sediment mass fluxes are similar for cropland and rangeland models at large surface crust coverage and aerodynamic roughness. In situations of small to moderate crust cover and soil roughness, horizontal mass fluxes varied by over three orders of magnitude among the tested models. A correlation analysis shows that horizontal mass fluxes simulated by cropland and rangeland models are correlated, with correlation R-2 of 0.37-0.99 across different models. Finally, we propose an approach to estimate changes in aeolian transport with changes in land use. Although this approach may be limited to situations of unvegetated surfaces, it provides a preliminary method for land managers and policymakers to estimate potential wind erosion changes in response to land use change.

Vegetation studies provide insight into the effectiveness of restoring wetland ecosystem functions. We compared plant community composition in 47 non-tidal wetlands under different management (natural, restored, and former wetlands that had been converted to cropland) in the Atlantic Coastal Plain of the USA. As expected, drained cropland sites were dominated by conventional upland row crops, had low species richness and evenness, and were highly disturbed. Plant communities in restored sites were more like natural sites based on the percentage of species that were native and hydrophytic, plant community evenness, and floristic quality. However, natural sites were forested, while restored and drained cropland sites were primarily herbaceous. Restored sites continued to be impacted by anthropogenic disturbance compared to natural sites. Our findings demonstrate that restored wetlands in agricultural settings can develop diverse native wetland plant communities within a decade but they remain very different from natural wetlands, raising questions about restoration goals, ecosystem service tradeoffs, and our ability to restore wetlands to ecological conditions found in reference sites.

In recent years, reproductive and meat quality traits have become more important because of increasing consumption, exports and consumer demand. The identification of genome regions altered by artificial selection can potentially permit a better understanding of the biology of specific phenotypes that are useful for the development of tools designed to increase selection efficiency. Therefore, the aims of this study were to detect evidence of recent selection signatures in Nellore cattle using extended haplotype homozygosity methodology and BovineHD marker genotypes (>777000 single nucleotide polymorphisms) as well as to identify corresponding genes underlying these signals. Thirty-one significant regions (P<0.0001) of possible recent selection signatures were detected, and 19 of these overlapped quantitative trait loci related to reproductive traits, growth, feed efficiency, meat quality, fatty acid profiles and immunity. In addition, 545 genes were identified in regions harboring selection signatures. Within this group, 58 genes were associated with growth, muscle and adipose tissue metabolism, reproductive traits or the immune system. Using relative extended haplotype homozygosity to analyze high-density single nucleotide polymorphism marker data allowed for the identification of regions potentially under artificial selection pressure in the Nellore genome, which might be used to better understand autozygosity and the effects of selection on the Nellore genome.

Currently, genomic resources for striped bass, white bass, and their hybrid lag behind those of other aquaculture species. Current resources consist of a medium-density genetic linkage map and a well-annotated ovarian transcriptome. A well-annotated transcriptome from across striped bass and white bass tissues is needed to advance both broad-based RNA-seq studies of gene expression as well as aid in more targeted studies of important genes and pathways critical for reproductive physiology and immunity. Here, we carried out Illumina-based transcriptome sequencing and annotation in both species utilizing the trinity and trinotate packages. The assembled Moronid reference transcriptomes and identified SSRs and SNPs should advance ongoing studies of reproduction, physiology, and immunology in these species and provide markers for broodstock management and selection.

Soil properties likely mediate these fungal responses but are rarely explored in CO2 experiments. We studied soil fungal communities in a grassland ecosystem exposed to a preindustrial-to-future CO2 gradient ( 250 to 500 ppm) in a black clay soil and a sandy loam soil. Sanger sequencing and pyrosequencing of the rRNA gene cluster revealed that fungal community composition and its response to CO2 differed significantly between soils. Fungal species richness and relative abundance of Chytridiomycota ( chytrids) increased linearly with CO2 in the black clay ( P < 0.04, R-2 > 0.7), whereas the relative abundance of Glomeromycota ( arbuscular mycorrhizal fungi) increased linearly with elevated CO2 in the sandy loam ( P = 0.02, R-2 = 0.63). Across both soils, decomposition rate was positively correlated with chytrid relative abundance ( r = 0.57) and, in the black clay soil, fungal species richness. Decomposition rate was more strongly correlated with microbial biomass ( r = 0.88) than with fungal variables. Increased labile carbon availability with elevated CO2 may explain the greater fungal species richness and Chytridiomycota abundance in the black clay soil, whereas increased phosphorus limitation may explain the increase in Glomeromycota at elevated O-2 in the sandy loam. Our results demonstrate that soil type plays a key role in soil fungal responses to rising atmospheric CO2. C1 [Procter, Andrew C.; Ellis, J.

Our group has identified both chicken and Eimeria MIFs, and characterized their function in enhancing innate immune responses during inflammation. In this study, we report that chicken CD74 (ChCD74), a type II transmembrane protein, functions as a macrophage surface receptor that binds to MIF molecules. First, to examine the binding of MW to chicken monocytes/macrophages, fresh isolated chicken peripheral blood mononuclear cells (PBMCs) were stimulated with rChIFN-gamma and then incubated with recombinant chicken MIF (rChMIF). Immunofluorescence staining with anti-ChMIF followed by flow cytometry revealed the binding of MIF to stimulated PBMCs. To verify that ChCD74 acts as a surface receptor for MIF molecules, full-length ChCD74p41 was cloned, expressed and its recombinant protein (rChCD74p41) transiently over-expressed with green fluorescent protein in chicken fibroblast DF-1 cells. Fluorescence analysis revealed a higher population of cells double positive for CD74p41 and rChMIF, indicating the binding of rChMIF to DF-1 cells via rChCD74p41. Using a similar approach, it was found that Eimeria MIF (EMIF), which is secreted by Eimeria sp. during infection, bound to chicken macrophages via ChCD74p41 as a surface receptor. Together, this study provides conclusive evidence that both host and parasite MIF molecules bind to chicken macrophages via the surface receptor ChCD74. (C) 2014 Elsevier Ltd. All rights reserved.

Evaluating the restoration status of these plantations is essential for their long-term management. Based on our previous work, we used an ecological memory (EM) approach to evaluate four 26-year-old plantations that represent four common kinds of plantations in subtropical China, i.e., mixed broad-leaved plantation (MBP), mixed coniferous plantation (MCP), eucalyptus plantation (EP), and mixed legume plantation (MLP). Comparing them with the regional climax community, i.e., monsoon evergreen broad-leaved forest (BF), all four plantations accumulated nearly the same pattern of EM during succession. EM was > 50 % for soil minerals, light conditions, soil age, soil animals, and soil microbes. EM was about 25 % for soil pollen and 10 % for birds, soil seed bank, and plant species. The total EM value of the four plantations ranged from 50.96 to 52.54, which indicated that all four plantations were in the regional, natural trajectory of succession and between the early and medium successional stages. The results indicated that natural succession processes are unlikely to be accelerated by planting late-stage tree species without sufficient EM. The results also demonstrated that all four plantations were in positive successional trajectories, and the positive succession dynamics were greater in the MLP and MCP. We suggest that the entire natural succession trajectory be used to evaluate the restoration of a site and that the ultimate restoration target be divided into several milestones along the reference trajectory to monitor progress. Forest restoration may be accelerated by starting with a minimum dynamic unit supporting sufficient EM.

The objective of this research was to study the response of strawberries to ClO2 when applied to the fruit using a controlled release pad. Four experiments were conducted over 2011 to 2013. Strawberries were packed in perforated commercial clamshells, with or without ClO2 treatments, and stored at 1 and 6 A degrees C for up to 14 days and at 10 and 20 A degrees C for up to 7 days. The effect of ClO2 on strawberries was assessed by measuring decay incidence, weight loss, firmness, volatile composition, and stomate activity during storage. Chlorine dioxide treatments induced closing of stomata, markedly slowed weight loss and softening, and reduced decay incidence of strawberry fruit at 10 A degrees C or lower temperatures, but not at 20 A degrees C. Fruit flavor profiles were not affected by ClO2 treatment.

Nutrim, oat bran concentrate (OBC), and whole oat flour (WOF) were composited with finely ground chia, and used in cookies at 20% replacement of wheat flour for improved nutritional and physical quality. The objective was to evaluate physical properties of chia-oat composites, dough, and cookies. RESULTSThese composites had improved water-holding capacities compared to the starting materials. The geometrical properties and texture properties of the cookies were not greatly influenced by a 20% flour replacement using chia-OBC or chia-WOF composites. There was a decrease in the cookie diameter, and increases in the height of cookies and dough hardness using 20% Chia- Nutrim composite. CONCLUSIONThese fine-particle chia-oat composites were prepared by a feasible procedure for improved nutritional value and physical properties of foods. The cookies containing chia-oat composites can be considered a health-promoting functional food. Published 2014. This article is a U.S. Government work and is in the public domain in the USA.

TI Net returns and risk for cover crop use in Alabama tomato production SO RENEWABLE AGRICULTURE AND FOOD SYSTEMS LA English DT Article DE cover crops; no-till; Solanum lycopersicum L.; subsoiler shank; tomato production ID FRESH-MARKET TOMATOES; ECONOMIC SUSTAINABILITY; NITROGEN-FERTILIZATION; NO-TILL; MANAGEMENT; SYSTEMS; PERFORMANCE; STRATEGIES; EFFICIENCY; ARKANSAS AB Tomato (Solanum lycopersicum L.) producers are faced with uncertain yields and prices, and utilizing a production system that will reduce risk while maintaining yield may keep tomato producers economically sustainable into the future. A conservation tillage production system with high biomass cover crops may be an economically viable alternative for tomato producers in Alabama. The objective of this study was to compare the economics of alternative production systems using different cover crops, such as cereal rye (Secale cereale L.) and crimson clover (Trifolium incarnatum L.), and different subsoiler shanks for fresh-market tomato production relative to a commonly used plastic mulch system to determine the preferred treatment. Gross revenues and net returns from tomato production using a rye cover crop were higher than tomato production using plastic mulch in 2 of the 4 years. For the clover cover crop, gross revenues and net returns were higher in 1 out of the 4 years. Under tomato prices and weather conditions observed during 2005-2008, the preferred treatment for a risk neutral producer was planting tomatoes into a rye cover crop with a wide shank. For a strongly risk averse producer, all cover crop treatments were preferred to plastic mulch. The use of a cover crop in tomato production has the potential to be an equally profitable, less risky alternative to plastic mulch in Alabama.

One possible cause is altered deposition chemistry; specifically, decreasing sulfate inputs leading to changes in ionic strength and dissolved organic carbon solubility. To further investigate the relationship between deposition chemistry and dissolved organic carbon export in peatlands, a field experiment was conducted to compare the pore water chemistry and peat microbial enzyme activity of mesocosms receiving sulfate amendments to mesocosms receiving no additions. To consider how peatlands respond during recovery from increased inputs of sulfate, samples were also analyzed from an area of the same peatland that was previously amended with sulfate. Current additions of sulfate decreased dissolved organic carbon concentration and increased dissolved organic carbon aromaticity. Total dissolved phosphorus decreased in response to current sulfate amendments but was elevated in the area of the peatland recovering from sulfate amendment. The total dissolved phosphorus increase, which was reflected in microbial enzyme activity, may have shifted the system from P limitation to N limitation. This shift could have important consequences for ecosystem processes related to plant and microbial communities. It also suggests that the recovery from previous sulfate amendments may take longer than may be expected. (C) 2014 Elsevier Ltd. All rights reserved. C1 [Seifert-Monson, L.

Many of these organisms, as with crop plants, are being engineered for applications in agriculture, to control plant insect pests or diseases. This paper reviews the genetically modified non-plant organisms that have been the subject of permit approvals for environmental release by the United States Department of Agriculture/Animal and Plant Health Inspection Service since the US began regulating genetically modified organisms. This is an indication of the breadth and progress of research in the area of non-plant genetically modified organisms. This review includes three examples of promising research on non-plant genetically modified organisms for application in agriculture: (1) insects for insect pest control using improved vector systems; (2) fungal pathogens of insects to control insect pests; and (3) virus for use as transient-expression vectors for disease control in plants.

TI Design and characterization of cellulose nanocrystal-enhanced epoxy hardeners SO GREEN MATERIALS LA English DT Article DE cellulose nanocrystals; epoxy; hardeners; mechanical properties; nanocomposite AB Cellulose nanocrystals (CNCs) are renewable, sustainable, and abundant nanomaterial widely used as reinforcing fillers in the field of polymer nanocomposites. In this study, two-part epoxy systems with CNC-enhanced hardeners were fabricated. Three types of hardeners, Jeffamine D400 (JD400), diethylenetriamine (DETA), and (+/-)-trans-1,2-diaminocyclohexane (DACH), were evaluated for their compatibility with CNC. The roles of CNC additions and hardener types in epoxy properties were analyzed with tensile testing and dynamic mechanical analysis. The CNC-reinforcing effects on epoxy depended on the structure of hardeners. For example, with less than 2 wt% CNC, Young's modulus was increased by 16% in JD400-cured epoxy and by 19% in DETA-cured epoxy, but had minimal effect for the DACH-cured epoxy. In general, the DETA-cured specimens had the highest increases in mechanical properties among the three hardeners evaluated. These results indicate that CNC additions to pre-formulated hardeners could be an alternative approach for dispersing CNCs within epoxy matrices and for improving the mechanical properties of epoxy. However, residual acetone and water during the curing reaction plasticized the epoxy matrices and must be limited for further property improvements.

TI BIOLOGICAL CONTROL OF SALTCEDAR (TAMARIX SPP.) BY SALTCEDAR LEAF BEETLES (DIORHABDA SPP.): EFFECTS ON SMALL MAMMALS SO WESTERN NORTH AMERICAN NATURALIST LA English DT Article ID UNITED-STATES; RIPARIAN RESTORATION; VEGETATION; COMMUNITIES; BIRDS AB The spread of introduced saltcedar (Tamarix spp.) throughout many riparian systems across the western United States motivated the introduction of saltcedar leaf beetles (Diorhabda carinulata, D. elongata; Chrysomelidae) as a biological control agent specific to saltcedar. I monitored small mammal populations for up to 12 years as saltcedar defoliation progressed at 3 of the original saltcedar beetle release sites and at an additional site where beetles established through dispersal. There was no evidence of any linear effect of increasing defoliation over time on small mammal species richness. Estimated population sizes of 4 small mammal species, based on mark-release-recapture trapping, showed linear responses to saltcedar defoliation at particular sites, but all of these species were represented by only 3 years of data at those sites. Increases in the abundance of 2 species of desert-adapted heteromyid rodents, Merriam's kangaroo rat (Dipodomys merriami) and Panamint kangaroo rat (D. panamintinus), may have occurred due to increasing habitat desertification associated with saltcedar biocontrol. Overall, however, results imply that saltcedar biological control is likely to have negligible effects on resident small mammal populations.

TI Effect of Oxygen on the Growth and Biofilm Formation of Xylella fastidiosa in Liquid Media SO CURRENT MICROBIOLOGY LA English DT Article ID PIERCES-DISEASE; FLUID CHEMISTRY; VITIS-ROTUNDIFOLIA; PLANT; BACTERIA; TREES; AGGREGATION; ETHANOL; METABOLISM; REPRESSOR AB Xylella fastidiosa is a xylem-limited bacterial pathogen, and is the causative agent of Pierce's disease of grapevines and scorch diseases of many other plant species. The disease symptoms are putatively due to blocking of the transpiration stream by bacterial-induced biofilm formation and/or by the formation of plant-generated tylosis. Xylella fastidiosa has been classified as an obligate aerobe, which appears unusual given that dissolved O-2 levels in the xylem during the growing season are often hypoxic (20-60 mu mol L-1). We examined the growth and biofilm formation of three strains of X. fastidiosa under variable O-2 conditions (21, 2.1, 0.21 and 0 % O-2), in comparison to that of Pseudomonas syringae (obligate aerobe) and Erwinia carotovora (facultative anaerobe) under similar conditions. The growth of X. fastidiosa more closely resembled that of the facultative anaerobe, and not the obligate aerobe. Xanthomonas campestris, the closest genetic relative of X. fastidiosa, exhibited no growth in an N-2 environment, whereas X. fastidiosa was capable of growing in an N-2 environment in PW+, CHARDS, and XDM2-PR media. The magnitude of growth and biofilm formation in the N-2 (0 % O-2) treatment was dependent on the specific medium. Additional studies involving the metabolism of X. fastidiosa in response to low O-2 are warranted. Whether X. fastidiosa is classified as an obligate aerobe or a facultative anaerobe should be confirmed by gene activation and/ or the quantification of the metabolic profiles under hypoxic conditions.

During an intense rainstorm in November 2006, seven debris flows initiated from proglacial gullies of separate basins on the flanks of Mount Rainier. Gully heads at glacier termini and widespread failure of gully walls imply that overland flow was transformed into debris flow along gullies. We characterized gully change and morphology, and assessed spatial distributions of debris flows to infer the processes and conditions for debris flow initiation. Slopes at gully heads were greater than similar to 0.35 m m(-1) (19 degrees) and exhibited a significant negative relationship with drainage area. A break in slope-drainage area trends among debris flow gullies also occurs at similar to 0.35 m m(-1), representing a possible transition to fluvial sediment transport and erosion. An interpreted hybrid model of debris flow initiation involves bed failure near gully heads followed by sediment recruitment from gully walls along gully lengths. Estimates of sediment volume loss from gully walls demonstrate the importance of sediment inputs along gullies for increasing debris flow volumes. Basin comparisons revealed significantly steeper drainage networks and higher elevations in debris flow-producing than non-debris flow-producing proglacial areas. The high slopes and elevations of debris flow-producing proglacial areas reflect positive slope-elevation trends for the Mount Rainier volcano. Glacier extent therefore controls the slope distribution in proglacial areas, and thus potential for debris flow generation. As a result, debris flow activity may increase as glacier termini retreat onto slopes inclined at angles above debris flow initiation thresholds. (C) 2014 Elsevier B.V. All rights reserved.

Evapotranspiration (ET) is a key component of the water balance and accurate estimates are important to quantify safe allocations to humans while supporting environmental needs. Scaling up ET measurements from small spatial scales has been problematic due to spatiotemporal variability. Remote sensing products provide spatially distributed data that account for seasonal climate and vegetation variability. We used MODIS products [i.e., Enhanced Vegetation Index (EVI) and nighttime land surface temperatures (LSTn)] to create empirical ET models calibrated using measured ET from three riparian-influenced and two upland, water-limited flux tower sites. Results showed that combining all sites introduced systematic bias, so we developed separate models to estimate riparian and upland ET. While EVI and LSTn were the main drivers for ET in riparian sites, precipitation replaced LSTn as the secondary driver of ET in upland sites. Riparian ET was successfully modeled using an inverse exponential approach (r(2) = 0.92) while upland ET was adequately modeled using a multiple linear regression approach (r(2) = 0.77). These models can be used in combination to estimate ET at basin scales provided each region is classified and precipitation data is available. (C) 2014 Elsevier Ltd. All rights reserved.

In southwestern USA, Chihuahuan Desert grasslands have experienced long-term encroachment by shrubs including creosotebush (Larrea tridentata). Land managers have attempted an ambitious intervention to control shrubs by spraying herbicides over extensive areas to provide grassland habitat for wildlife species of conservation concern. To provide a broader assessment of how these restoration practices affect biodiversity, we evaluated responses by four mound-building ant species (Pogonomyrmex rugosus, Aphaenogaster cockerelli, Myrmecocystus depilis, and Myrmecocystus mexicanus). We compared colony densities between 14 pairs of treated areas (herbicide applied 10-30 years before sampling) and untreated areas (spatially matched and dominated by creosotebush). P. rugosus and A. cockerelli responded positively to restoration treatments likely due to an increased abundance of seeds associated with increased grass cover. Variation in P. rugosus densities among different-aged treatments suggests a substantial time lag in response that could reflect temporal changes in habitat quality or facilitation by a keystone rodent, Dipodomys spectabilis. Colony densities of the scavenging ant M. mexicanus were reduced on treated areas, and M. depilis exhibited a similar trend, likely reflecting a reduction of liquid food resources associated with shrubs. Our results demonstrate that ongoing efforts to restore Chihuahuan Desert grasslands are having both positive and negative effects on non-target taxa such as ants and support the need for a landscape mosaic approach to restoration.

TI Soil sterilization alters interactions between the native grass Bouteloua gracilis and invasive Bromus tectorum SO JOURNAL OF ARID ENVIRONMENTS LA English DT Article DE Competition; Great Plains; Plant-soil feedback; Soil microbes ID NITROGEN AVAILABILITY; CENTAUREA-MACULOSA; MYCORRHIZAL FUNGI; COMMUNITIES; DIVERSITY; FEEDBACK; DYNAMICS; ECOLOGY; BIOTA AB The invasive grass Bromus tectorum negatively impacts grass and shrublands throughout the western U.S., particularly in arid and semiarid regions. We asked whether soil microbes associated with a native grass (Bouteloua gracilis) affect growth of Bromus and competition between Bromus and Bouteloua. We also examined whether plant responses varied between soils from 15 sites in the Northern Great Plains. Bromus and Bouteloua were grown in media with sterilized or unsterilized soil, alone and together. Soil sterilization reduced biomass of Bouteloua and Bromus grown alone by an estimated 50% and 48%, respectively. Additionally, results provided evidence that sterilization increased the effect of competition on Bromus, and may have reduced the effect of competition on Bouteloua. Bouteloua likely had a stronger negative effect on Bromus in sterilized soils because sterilization reduced Bromus biomass by a greater absolute amount. Response to sterilization varied appreciably by site for Bromus, but not Bouteloua. Our results support the hypothesis that invasive species such as Bromus often have positive responses to soil biota in the invaded range. Soil microbes are one factor that may be important in determining dynamics of plant invasions, and plant responses to new sites and competition with natives. (C) 2014 Elsevier Ltd.

Carcass conformation score was greater (P = 0.08) when meat-goat kids were finished on ALF compared to OCR with RCG intermediate. Chevon meat samples from goats finished on the three pasture treatments did not differ in ash, intramuscular fat, or crude protein content or in concentrations of omega6 and omega3 fatty acids, or the omega6 to omega3 ratio. Goats finished on OCR had higher (P < 0.001) 18:1 trans-11 fatty acids (FA) compared to ALP or RCG. Overall, meat-goat kids finished on ALF, RCG, or ORG produced desirable carcass weights for most niche markets in the USA. Chevon is a low-fat meat option with high desirable fatty acids for human diets. Published by Elsevier Ltd. C1 [Turner, K. E.] ARS, USDA, Grazinglands Res Lab, El Reno, OK 73036 USA. [Cassida, K.

The disinfection mechanism was determined by the release of cellular K+, lipid oxidation, and the TEM morphological images. Photocatalytic treatments showed the similar effects on both G(-) and G(+) bacteria regardless of experimental conditions and disinfection mechanism. The lower the initial bacterial population was, the shorter the time that was required to eliminate the bacteria. Increased TiO2 contents and light intensity resulted in increased bacterial killing. Both K leakage and lipid oxidation increased significantly after the TiO2 treatment. Electronic images illustrate that bacterial cells started showing damages in cell walls and membranes after 30 min treatment, cytoplasm leakage after 90 min treatment, and lysis after 150 min treatment. The greater reduction population of M. caseolyticus was observed than that of P. fluorescens. These results demonstrate that effectiveness of nano-TiO2 depends on the initial bacterial population, TiO2 content, and UVA light intensity. TiO2 treatments results in increased lipid peroxidation and damaged cell membrane integrity before cell death. G(+) M. caseolyticus is more susceptible to photocatalytic disinfection by nano-TiO2 under light than G(-) P. fluorescens regardless of experimental conditions. (C) 2014 Elsevier Ltd.

Although flowing grain can behave like a continuum fluid at times, the discontinuous behavior exhibited by grain kernels cannot be simulated solely with conventional continuum-based computer modeling such as finite-element or finite-difference methods. The discrete element method (DEM) is a proven numerical method that can model discrete particles like grain kernels by tracking the motion of individual particles. DEM has been used extensively in the field of rock mechanics. Its application is gaining popularity in grain postharvest operations, but it has not been applied widely. This paper reviews existing applications of DEM in grain postharvest operations. Published literature that uses DEM to simulate postharvest processing is reviewed, as are applications in handling and processing of grain such as soybean, corn, wheat, rice, rapeseed, and the grain coproduct distillers dried grains with solubles (DDGS). Simulations of grain drying that involve particles in both free-flowing and confined-flow conditions are also included. Review of the existing literature indicates that DEM is a promising approach in the study of the behavior of deformable soft particulates such as grain and coproducts, and it could benefit from the development of improved particle models for these complex-shaped particles.

TI Wildfire exposure and fuel management on western US national forests SO JOURNAL OF ENVIRONMENTAL MANAGEMENT LA English DT Article DE Wildfire risk; Wildfire exposure; National forest; Risk assessment; Burn probability ID UNITED-STATES; WILDLAND FIRE; NORTHERN ROCKIES; CALIFORNIA; LANDSCAPE; RISK; SIMULATION; CHALLENGES; SHRUBLANDS; VEGETATION AB Substantial investments in fuel management activities on national forests in the western US are part of a national strategy to reduce human and ecological losses from catastrophic wildfire and create fire resilient landscapes. Prioritizing these investments within and among national forests remains a challenge, partly because a comprehensive assessment that establishes the current wildfire risk and exposure does not exist, making it difficult to identify national priorities and target specific areas for fuel management. To gain a broader understanding of wildfire exposure in the national forest system, we analyzed an array of simulated and empirical data on wildfire activity and fuel treatment investments on the 82 western US national forests. We first summarized recent fire data to examine variation among the Forests in ignition frequency and burned area in relation to investments in fuel reduction treatments. We then used simulation modeling to analyze fine-scale spatial variation in burn probability and intensity. We also estimated the probability of a mega-fire event on each of the Forests, and the transmission of fires ignited on national forests to the surrounding urban interface. The analysis showed a good correspondence between recent area burned and predictions from the simulation models. The modeling also illustrated the magnitude of the variation in both burn probability and intensity among and within Forests. Simulated burn probabilities in most instances were lower than historical, reflecting fire exclusion on many national forests. Simulated wildfire transmission from national forests to the urban interface was highly variable among the Forests. We discuss how the results of the study can be used to prioritize investments in hazardous fuel reduction within a comprehensive multi-scale risk management framework. Published by Elsevier Ltd.

TI Tillage and straw management affect PM10 emission potential in subarctic Alaska SO SOIL & TILLAGE RESEARCH LA English DT Article DE Aggregate size distribution; Air quality; Dust; SWEEP; Wind erosion ID EROSION PREDICTION SYSTEM; LONG-RANGE TRANSPORT; WIND EROSION; COLUMBIA PLATEAU; WINDBLOWN DUST; CROP RESIDUE; CONSERVATION TILLAGE; WHEAT-FALLOW; ASIAN DUST; SOIL AB Emission of windblown dust and PM10 (particulates <= 10 mu m in diameter regulated by many nations as an air pollutant) from agricultural soils can impact regional air quality. Little information exists that describes the potential for PM10 and airborne dust emissions from subarctic soils or agricultural soils subject to different tillage and residue management. This study documents the influence of tillage and residue management on fine particulate emissions from a subarctic soil in Interior Alaska. Surface characteristics and properties of a silt loam soil subject to conventional, spring disk, autumn chisel plow, and no tillage, with stubble and loose straw retained or removed from the soil surface after harvest of continuous barley (Hordeum vulgare L.), was measured twenty years after establishing treatments. These soil characteristics and properties were used to simulate PM10 emission potential and soil loss from tillage and residue treatments using the Single-event Wind Erosion Evaluation Program (SWEEP). Primary particle size analysis indicated no statistical difference in the size of primary soil particles among tillage or residue treatments. Aggregate size distribution analysis showed that tillage affected the freely-available PM10 content of the soil in the field. No tillage resulted in the lowest freely-available PM10 content as compared with other tillage treatments. Simulations made with SWEEP suggest that PM10 emissions and soil loss are potentially highest for conventional tillage and lowest for no tillage while emissions and soil loss were lower from spring disk than autumn chisel plow. Tillage practices can therefore affect air quality and long range transport of fine particulates emitted into the atmosphere during high wind events in subarctic Alaska. Published by Elsevier B.V.

TI Urban tree cover change in Detroit and Atlanta, USA, 1951-2010 SO CITIES LA English DT Article DE Air photo interpretation; Canopy cover; Urban forestry; Simple random sampling ID CANOPY COVER; FOREST COVER; DRIVERS; CITY; EXTRACTION; CITIES AB We assessed tree cover using random points and polygons distributed within the administrative boundaries of Detroit, MI and Atlanta, GA. Two approaches were tested, a point-based approach using 1000 randomly located sample points, and polygon-based approach using 250 circular areas, 200 m in radius (12.56 ha). In the case of Atlanta, both approaches arrived at similar estimates of tree cover (50-53%) for both time periods, yet they show that roughly one-third of the tree-covered land area in 1951 was also tree-covered in 2010 and about 30-31% of the sampled land area lacked tree cover during both assessment periods. In the case of Detroit, the two approaches resulted in different estimates of tree cover (19.6% vs. 30.8% in 2010), yet similar levels of transitions over time. The only similarities between the two cities were that about 15-20% of each city's land area was covered with trees in 1951, yet lacked tree cover in 2010. While the polygon-based approach to estimating tree cover may result in a product that more explicitly represents covered areas, the point-based approach is recommended due to the time and effort involved with the polygon-based approach and potential error introduced through topographic displacement of trees and shadows. Overall, canopy cover over time remained stable while distribution varied greatly. However, while multi-decade change in aggregate is undetectable at the scale of a city, there seems to be substantial shifts in the spatial arrangement of the tree canopy. (c) 2014 Elsevier Ltd.

In this study, three hyperspectral imaging (HSI) configurations coupled with two multivariate image analysis techniques are compared for detection of fecal contamination on spinach leaves (Spinacia oleracea). Fluorescence imaging in the visible region with ultra violet (UV) and violet excitation sources, and reflectance imaging in the visible to near-infrared regions were investigated. Partial least squares discriminant analysis and two band ratio analysis techniques were used to compare these HSI configurations. High detection accuracy was found for the two fluorescence HSI configurations compared to the visible/near infrared HSI. Both fluorescence HSI configurations had 100% detection rates for fecal contamination up to 1:10 dilution level and violet HSI had 99% and 87% detection rates for 1:20 and 1:30 levels, respectively. Results indicated that fluorescence imaging with the violet excitation performed superior to HSI with UV excitation for detection of a range of diluted fecal contamination on leafy greens. 5% or less false positives were observed for the fluorescence HSI configurations and were associated with yellow hue on the leaves. On-line detection of fecal contamination on leaves has the potential to reduce the cases of food borne illnesses and their associated costs. (C) 2014 Elsevier Ltd. All rights reserved.

While standard 16-day and 250-m Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation index (VI)-based springtime LSP has been evaluated in previous studies, it remains unclear whether LSP with enhanced temporal and spatial resolutions can capture additional details of ground phenology. In this paper, we compared LSP derived from 500-m daily MODIS and 30-m MODIS-Landsat fused VI data with landscape phenology (LP) in a northern U. S. mixed forest. LP was previously developed from intensively observed deciduous and coniferous tree phenology using an upscaling approach. Results showed that daily MODIS-based LSP consistently estimated greenup onset dates at the study area (625 m x 625 m) level with 4.48 days of mean absolute error (MAE), slightly better than that of using 16-day standard VI (4.63 days MAE). For the observed study areas, the time series with increased number of observations confirmed that post-bud burst deciduous tree phenology contributes the most to vegetation reflectance change. Moreover, fused VI time series demonstrated closer correspondences with LP at the community level (0.1-20 ha) than using MODIS alone at the study area level (390 ha). The fused LSP captured greenup onset dates for respective forest communities of varied sizes and compositions with four days of the overall MAE. This study supports further use of spatiotemporally enhanced LSP for more precise phenological monitoring. C1 [Liang, Liang] Univ Kentucky, Dept Geog, Lexington, KY 40506 USA.

While sprouts, which have frequently been implicated in foodbome illness outbreaks, are the subject of numerous national and international standards for their production and distribution, there is a lack of data pertaining to the microbiological safety of microgreens. In this study, sprouts and microgreens were produced from radish seeds inoculated with Escherichia coli O157: H7 or O104: H4 and E. coli populations on the harvested products compared to assess the potentials of product contamination from contaminated seeds during sprouting and microgreen production. Both E. coli O157:H7 and O104:H4 grew rapidly during sprouting, reaching levels of 5.8-8.1 log cfu/g and 5.2-73 log cfu/g, respectively, depending on the initial inoculation levels of the seeds (1.5-4.6 log cfu/g and 0.8-43 log cfu/g on radish seeds, respectively). In comparison, E. coli O157:H7 and O104:H4 populations on harvested microgreens ranged from 0.8 to 4.5 log cfu/g and from 0.6 to 4.0 log cfu/g, respectively. Although harvested microgreens carried significantly less (P < 0.001) E. coli than sprouts germinated from seeds inoculated at the same levels, proliferation of E. coli O157:H7 and O104:H4 occurred during both sprouting and microgreen growth.

Detection of hepatitis A virus was also considered. Thirteen primer pairs were designed for use in this assay and a reference database was created using GenBank sequences and reference norovirus samples. The assay was tested for inclusivity and exclusivity using 160 clinical norovirus samples, 3 samples of hepatitis A virus and 3 other closely related viral strains. Results showed that the assay was able to detect norovirus with a sensitivity of 92% and a specificity of 100%. Norovirus identification at the genogroup level was correct for 98% of samples detected by the assay and for 75% of a subset of samples (n = 32) compared at the genotype level. Identification of norovirus genotypes is expected to improve as more reference samples are added to the database. The assay was also capable of detecting and genotyping hepatitis A virus in all 3 samples tested. Overall, the assay developed here allows for detection and differentiation of noroviruses within one working day and may be used as a tool in surveillance efforts or outbreak investigations.

TI Natural rpoS mutations contribute to population heterogeneity in Escherichia coli O157:H7 strains linked to the 2006 US spinach-associated outbreak SO FOOD MICROBIOLOGY LA English DT Article DE Escherichia coli O157:H7; Curli; rpoS; Transcriptomic; Stress fitness; Population heterogeneity ID PATHOADAPTIVE MUTATIONS; SALMONELLA-ENTERICA; STATIONARY-PHASE; ACID RESISTANCE; BACTERIAL PATHOGENS; BACILLUS-SUBTILIS; CURLI EXPRESSION; GENE-EXPRESSION; CSGD PROMOTER; FIMH ADHESIN AB We previously reported significantly different acid resistance between curli variants derived from the same Escherichia coli O157:H7 strain, although the curli fimbriae were not associated with this phenotypic divergence. Here we investigated the underlying molecular mechanism by examining the genes encoding the common transcriptional regulators of curli biogenesis and acid resistance. rpoS null mutations were detected in all curli-expressing variants of the 2006 spinach-associated outbreak strains, whereas a wild-type rpoS was present in all curli-deficient variants. Consequently curli-expressing variants were much more sensitive to various stress challenges than curli-deficient variants. This loss of general stress fitness appeared solely to be the result of rpoS mutation since the stress resistances could be restored in curli-expressing variants by a functional rpoS. Comparative transcriptomic analyses between the curli variants revealed a large number of differentially expressed genes, characterized by the enhanced expression of metabolic genes in curli-expressing variants, but a marked decrease in transcription of genes related to stress resistances. Unlike the curli-expressing variants of the 1993 US hamburger-associated outbreak strains (Applied Environmental Microbiology 78: 7706-7719), all curli-expressing variants of the 2006 spinach-associated outbreak strains carry a functional rcsB gene, suggesting an alternative mechanism governing intra-strain phenotypic divergence in E. coli O157:H7.

In 2006, C. botulinum was responsible for an international outbreak of botulism attributed to the consumption of commercially pasteurized carrot juice. The purpose of this study was to isolate and characterize strains of C. botulinum from the adulterated product. Carrot juice bottles retrieved from the manufacturing facility were analyzed for the presence of BoNT and BoNT-producing isolates using DIG-ELISA. Toxigenic isolates from the carrot juice were analyzed using pulsed-field gel electrophoresis (PFGE) and DNA microarray analysis to determine their genetic relatedness to the original outbreak strains CDC51348 and CDC51303. PFGE revealed that isolates CJ4-1 and CJ10-1 shared an identical pulsotype with strain CDC51303, whereas isolate CJ5-1 displayed a unique restriction banding pattern. DNA microarray analysis identified several phage related genes unique to strain CJ5-1, and Southern hybridization analysis of Xhol digested and non-digested DNA showed their chromosomal location, while a homolog to pCLI_A009 of plasmid pCLI of C botulinum serotype Langeland F, was located on a small plasmid. The acquisition or loss of bacterio-phages and other mobile genetic elements among C. botulinum strains has epidemiological and evolutionary implications. Published by Elsevier Ltd.

Though not considered a foodborne pathogen, Y pestis can survive, and even grow, in some foods, and the foodborne route of transmission is not without precedent. As such, concerns exist over the possible intentional contamination of foods with this deadly pathogen. Here we report the inactivation of avirulent (pYV-minus) strains of Y. pestis by ultraviolet light (UV-C, 254 nm). Two strains of Y. pestis containing an intact pgm virulence locus (pgm(+)) and strains from which the pgm locus was spontaneously deleted (Delta pgm) were tested using cells grown in both logarithmic and stationary phase. The D-10 values for inactivation (the UV-C dose required to inactivate one log of bacterial cells) of Y. pestis on the surface of agar plates ranged from 0.69 to 1.09 mJ/cm(2). A significant difference was observed between the inactivation of cells of Y. pestis strain Yokohama grown in logarithmic and stationary phases, but no significant difference between growth phase sensitivity to UV-C was observed in Y. pestis strain Kuma. No difference in D-10 values was observed between pgm(+) and Delta pgm strains of Yokohama grown to either logarithmic or stationary phase. A measurable difference was observed between the D-10 of Kuma pgm(+) and Kuma Delta pgm grown in logarithmic phase, but this difference was diminished in the Kuma strains grown to stationary phase. Though strain variations exist, the results showing that UV-C can inactivate Y. pestis cells on agar surfaces suggest that UV-C would be effect in inactivating Y pestis on food surfaces, particularly foods with a smooth surface.

As compared to the raw corn, thermal treatment caused significant (p <= 0.05) decreases in each antioxidant compound and antioxidant activity. Steam cooking preserved more antioxidant compounds than boiling. Boiling caused a significant loss of anthocyanin and phenolic compounds into the cooking water. This cooking water is a valuable co-product because it is a good source of purple pigment. By comparing levels of antioxidant compounds in raw and cooked corn, we determined that degradation results in greater loss than leaching or diffusion into cooking water. Additionally, separation of kernels from the cob prior to cooking caused increased loss of antioxidant compounds. (C) 2014 Elsevier Ltd. All rights reserved.

Juice cloud is a complex mixture of polysaccharides, proteins and lower molecular weight compounds that are responsible for the turbid appearance of citrus juices. The stability of juice cloud depends on a number of factors, including pectin degree of methylation (DM) and the availability of sufficiently-sized, charged demethylated blocks, but detailed information on the precise relationship between cloud state and pectin architecture is limited. To address this gap, we have systematically treated commercial frozen concentrated orange juice (FCOJ) with pectin methylesterases extracted from orange pulp cells to mimic the aggregation of pectin that naturally occurs in the presence of calcium in unpasteurized or under pasteurized juice. We then assessed the pectin structural and functional properties, including juice optical density (OD) and soluble sugar composition, DM, degree of blockiness (DB), degree of absolute blockiness (DBabs) and rheological capacity from juice in various states of cloud loss. A strong positive correlation ([r] = 0.916) was observed between juice OD and DM, while a strong negative correlation ([r] = -0.914) was observed between OD and DBabs. Most critically, a reduction of average DM from 74.7% to 68.3% in the course of cloud loss resulted in the formation of rheologically active pectin. Published by Elsevier Ltd.

The material adsorbed onto the surface of the oil droplets in the oil phase was desorbed using surfactant. The desorbed CFG and the non-adsorbed CFG that remained present in the aqueous phase were collected, precipitated using alcohol and freeze dried. Their sugar composition, phenolic acid, lipid and protein contents were determined. There was no consistent difference observed in the sugar composition, phenolic acid and lipid contents of the original material and the adsorbed and non-adsorbed fractions. There was, however, a significant difference in the protein contents with the adsorbed fraction containing similar to 10.7% protein compared to 3.90% and 2.87% for the original and non-adsorbed CFG samples respectively. The three samples were also found to have very similar molecular mass distributions and each showed the presence of two peaks using refractive index detection. The major peak, corresponding to similar to 95% of the total, had a molecular mass of similar to 650,000 g/mol and the minor peak corresponded to a molecular mass of similar to 90,000 g/mol. The corresponding UV elution profiles indicated that the minor peak contained a significant proportion of phenolic and/or proteinaceous material. Published by Elsevier Ltd.

Concentrations of tropospheric O-3 ([O-3] have more than doubled since the Industrial Revolution, and are high enough to damage plant productivity. Soybean (Glycine max L. Merr.) is the world's most important legume crop and is sensitive to O-3. Current ground-level [O-3] are estimated to reduce global soybean yields by 6% to 16%. In order to understand transcriptional mechanisms of yield loss in soybean, we examined the transcriptome of soybean flower and pod tissues exposed to elevated [O-3] using RNA-Sequencing. Results: Elevated [O-3] elicited a strong transcriptional response in flower and pod tissues, with increased expression of genes involved in signaling in both tissues. Flower tissues also responded to elevated [O-3] by increasing expression of genes encoding matrix metalloproteinases (MMPs). MMPs are zinc- and calcium-dependent endopeptidases that have roles in programmed cell death, senescence and stress response in plants. Pod tissues responded to elevated [O-3] by increasing expression of xyloglucan endotransglucosylase/hydrolase genes, which may be involved with increased pod dehiscence in elevated [O-3]. Conclusions: This study established that gene expression in reproductive tissues of soybean are impacted by elevated [O-3], and flowers and pods have distinct transcriptomic responses to elevated [O-3].

TI Transcriptomic events associated with internal browning of apple during postharvest storage SO BMC PLANT BIOLOGY LA English DT Article DE Apple fruit; Browning disorder; Metabolic pathways; Postharvest physiology; RNA sequencing; Transcriptomics ID MALUS-X-DOMESTICA; CONTROLLED-ATMOSPHERE STORAGE; COENZYME-A REDUCTASE; ASCORBIC-ACID; FRUIT-DEVELOPMENT; CONFERENCE PEARS; GENE-EXPRESSION; SUCCINATE-DEHYDROGENASE; PLANTS; ANNOTATION AB Background: Postharvest ripening of apple (Malus x domestica) can be slowed down by low temperatures, and a combination of low O-2 and high CO2 levels. While this maintains the quality of most fruit, occasionally storage disorders such as flesh browning can occur. This study aimed to explore changes in the apple transcriptome associated with a flesh browning disorder related to controlled atmosphere storage using RNA-sequencing techniques. Samples from a browning-susceptible cultivar ('Braeburn') were stored for four months under controlled atmosphere. Based on a visual browning index, the inner and outer cortex of the stored apples was classified as healthy or affected tissue. Results: Over 600 million short single-end reads were mapped onto the Malus consensus coding sequence set, and differences in the expression profiles between healthy and affected tissues were assessed to identify candidate genes associated with internal browning in a tissue-specific manner. Genes involved in lipid metabolism, secondary metabolism, and cell wall modifications were highly modified in the affected inner cortex, while energy-related and stress-related genes were mostly altered in the outer cortex. The expression levels of several of them were confirmed using qRT-PCR. Additionally, a set of novel browning-specific differentially expressed genes, including pyruvate dehydrogenase and 1-aminocyclopropane-1-carboxylate oxidase, was validated in apples stored for various periods at different controlled atmosphere conditions, giving rise to potential biomarkers associated with high risk of browning development. Conclusions: The gene expression data presented in this study will help elucidate the molecular mechanism of browning development in apples at controlled atmosphere storage. A conceptual model, including energy-related (linked to the tricarboxylic acid cycle and the electron transport chain) and lipid-related genes (related to membrane alterations, and fatty acid oxidation), for browning development in apple is proposed, which may be relevant for future studies towards improving the postharvest life of apple.

Using DNA metabarcoding data from hundreds of globally distributed soil samples, we demonstrate that fungal richness is decoupled from plant diversity. The plant-to-fungus richness ratio declines exponentially toward the poles. Climatic factors, followed by edaphic and spatial variables, constitute the best predictors of fungal richness and community composition at the global scale. Fungi show similar latitudinal diversity gradients to other organisms, with several notable exceptions. These findings advance our understanding of global fungal diversity patterns and permit integration of fungi into a general macroecological framework.

However, the performance of conventional filtering schemes can be degraded by ignoring the time lag between soil moisture and discharge responses. This has led to ongoing development of more appropriate ways to implement sequential data assimilation. In this paper, an ensemble Kalman smoother (EnKS) with fixed time window is implemented for the GR4H hydrologic model (modele du Genie Rural a 4 parametres Horaire) to update current and antecedent model states. Model and observation error parameters are estimated through the maximum a posteriori method constrained by prior information drawn from flow gauging data. When evaluated in a hypothetical forecasting mode using observed rainfall, the EnKS is found to be more stable and produce more accurate discharge forecasts than a standard ensemble Kalman filter (EnKF) by reducing the mean of the ensemble root mean squared error (MRMSE) by 13-17%. The latter tends to over-correct current model states and leads to spurious peaks and oscillations in discharge forecasts. When evaluated in a real-time forecasting mode using rainfall forecasts from a numerical weather prediction model, the benefit of the EnKS is reduced as uncertainty in rainfall forecasts becomes dominant, especially at large forecast lead time.

TI The impacts of assimilating satellite soil moisture into a rainfall-runoff model in a semi-arid catchment SO JOURNAL OF HYDROLOGY LA English DT Article DE Data assimilation; Soil moisture; Flood prediction; Satellite retrievals; Rescaling; Rainfall-runoff models ID IN-SITU OBSERVATIONS; KALMAN FILTER; SEQUENTIAL ASSIMILATION; DISCHARGE PREDICTIONS; HYDROLOGICAL MODEL; ERS SCATTEROMETER; SURFACE; SCALE; RETRIEVALS; ASCAT AB Soil moisture plays a key role in runoff generation processes, and the assimilation of soil moisture observations into rainfall runoff models is regarded as a way to improve their prediction accuracy. Given the scarcity of in situ measurements, satellite soil moisture observations offer a valuable dataset that can be assimilated into models; however, very few studies have used these coarse resolution products to improve rainfall runoff model prediction. In this work we evaluate the assimilation of satellite soil moisture into the probability distributed model (PDM) for the purpose of reducing flood prediction uncertainty in an operational context. The surface soil moisture (SSM) and the soil wetness index (SWI) derived from the Advanced Microwave Scanning Radiometer (AMSR-E) are assimilated using an ensemble Kalman filter. Two options for the observed data are considered to remove the systematic differences between SSM/SWI and the model soil moisture prediction: linear regression (LR) and anomaly-based cumulative distribution function (aCDF) matching. In addition to a complete period rescaling scheme (CP), an operationally feasible real-time rescaling scheme (RT) is tested. On average, the discharge prediction uncertainty, expressed as the ensemble mean of the root mean squared difference (MRMSD), is reduced by 25% after assimilation and little overall difference is found between the various approaches. However, when specific flood events are analysed, the level of improvement varies. Our results reveal that efficacy of the soil moisture assimilation for flood prediction is robust with respect to different assumptions regarding the observation error variance. The assimilation performs similarly between the operational RT and the CP schemes, which suggests that short-term training is sufficient to effectively remove observation biases. Regarding the different rescaling techniques used, aCDF matching consistently leads to better assimilation results than LR. Differences between the assimilation of SSM and SWI, however, are not significant. Even though there is improvement in streamflow prediction, the assimilation of soil moisture shows limited capability in error correction when there exists a large bias in the peak flow prediction. Findings of this work imply that proper pre-processing of observed soil moisture is critical for the efficacy of the data assimilation and its performance is affected by the quality of model calibration.

For many years, water flow through woodchips has been assumed laminar without proper validation. The main objective of this study was to validate Darcy's laminar flow assumption for woodchips. For this purpose, we conducted both constant head laboratory column experiments and field evaluation of a denitrification bed. Laboratory results revealed that Darcy's law does not apply for the majority of the hydraulic gradients forcing flow through fresh and old woodchip media. However, Forchheimer's equation adequately described the flow pattern using a quadratic equation. Statistical analysis showed that old woodchips (excavated from a denitrification bed) had significantly lower intrinsic permeability than fresh woodchips. We determined Forchheimer's and Darcy's in-situ coefficients, and used them to predict flow rate in a denitrification bed. Model evaluation statistics showed better flow rate prediction with Forchheimer's than Darcy's equation when compared with the measured flow rate. In conclusion, the linear flow assumption was inadequate for describing water flow through woodchips in a denitrification bed. (C) 2014 Elsevier B.V. All rights reserved.

TI Snow distribution, melt and surface water inputs to the soil in the mountain rain-snow transition zone SO JOURNAL OF HYDROLOGY LA English DT Article DE Snowmelt; Surface water inputs; Soil water inputs; Snow model; Energy balance; Rain on snow ID COVER ENERGY-BALANCE; ON-SNOW; STREAMFLOW GENERATION; TEMPERATURE-INDEX; SOLAR-RADIATION; GROUNDWATER RECHARGE; PRECIPITATION PHASE; SPATIAL VARIABILITY; COMPLEX TERRAIN; SIERRA-NEVADA AB The timing, magnitude, and spatial distribution of snow cover and the resulting surface water inputs (SWI) are simulated at a small catchment located in the rain-snow transition zone of southwest Idaho, USA. A physically based snow model is run on this 1.5 ha study catchment, which has an elevation range of 1600-1645 masl. The catchment is divided into relatively steep (mean slope angle of 21 degrees) northeast and southwest facing hill slopes by an ephemeral stream that drains to the southeast. SWI are fundamental controls on soil moisture, streamflow generation, groundwater recharge, and nutrient cycling. Although the timing of melt events is similar across the basin, southwest facing slopes receive smaller magnitude and more frequent SWI from mid winter snow melt, while the northeast facing slope receives greater SWI during the spring. Three spatial patterns are observed in the modeled SWI time series: (1) equal between slopes, (2) majority of SWI on southwest facing slopes, and (3) majority of SWI on northeast facing slopes. Although any of these three spatial patterns can occur during the snow season, four emergent SWI patterns emerge through the melt season: (1) near uniform, (2) controlled by topographic differences in energy fluxes, (3) transitional, and (4) controlled by snow distribution. Rain on snow (ROS) events produce similar SWI between the northeast and southwest facing slopes, with the difference being attributed primarily to snow distribution. Turbulent fluxes dominate the snowpack energetics in four of the five rain on snow events, and advective fluxes from precipitation are greater than 17% during the 2 rain on snow events in December and January. Net radiation fluxes dominate spring melt events. Variations in the method used to distribute precipitation may result in large differences in total precipitation to the basin. (C) 2014 Elsevier B.V.

TI Effect of subsurface drainage on streamflow in an agricultural headwater watershed SO JOURNAL OF HYDROLOGY LA English DT Article DE Tile; Drainage; Hydrology; Agriculture; Discharge ID GROUNDWATER-FLOW; TILE DRAINS; IOWA; HYDROLOGY; SOIL; USA; CATCHMENT; TRANSPORT; DISCHARGE; BASEFLOW AB Artificial drainage, also known as subsurface or tile drainage is paramount to sustaining crop production agriculture in the poorly-drained, humid regions of the world. Hydrologic assessments of individual plots and fields with tile drainage are becoming common; however, a major void exists in our understanding of the contribution of systematic tile drainage to watershed hydrology. A headwater watershed (4 km(2)) in central Ohio, USA and all functioning tile were monitored from 2005 to 2010 in order to characterize the magnitude and frequency of flows, quantify the role and seasonal contributions of tile drainage to watershed hydrology, and relate tile drainage to precipitation and antecedent conditions. Results indicated that tile drainage contributions to watershed hydrology were significant. Specifically, 21% of precipitation (206 mm) was recovered through tile drainage annually. Tile drainage also accounted for 47% of watershed discharge and was seasonally variable. Median monthly tile discharges in winter (23.4 mm), spring (10.2 mm), and fall (15.6 mm) were significantly greater (P < 0.05) than the median monthly summer discharge (0.9 mm). Results from this study will help enhance hydrology and water quality prediction technologies as well as the design and implementation of best management practices that address water quality concerns.

TI Modeling runoff and microbial overland transport with KINEROS2/STWIR model: Accuracy and uncertainty as affected by source of infiltration parameters SO JOURNAL OF HYDROLOGY LA English DT Article DE Bacteria; Runoff; Uncertainty; Modeling; Infiltration parameters ID SOIL-WATER RETENTION; ARTIFICIAL NEURAL-NETWORK; VEGETATIVE FILTER STRIPS; HYDRAULIC CONDUCTIVITY; PEDOTRANSFER FUNCTIONS; COLIFORM BACTERIA; BROOKS-COREY; BULK-DENSITY; FLOW; SCALE AB Infiltration is important to modeling the overland transport of microorganisms in environmental waters. In watershed- and hillslope scale-models, infiltration is commonly described by simple equations relating infiltration rate to soil saturated conductivity and by empirical parameters defining changes in infiltration rate with soil water content. For the microbial transport model KINEROS2/STWIR used in this study, infiltration in unsaturated soil is accounted for by a net capillary drive parameter, G, in the Parlange equation. Scarce experimental data and multiple approaches for estimating parameter G introduce uncertainty, reducing reliability of overland water flow and microbial transport models. Our objectives were to evaluate reliability and robustness of three methods to estimate parameter G and associated accuracy and uncertainty in predicting runoff and fecal coliform (FC) transport. These methods include (i) KINEROS2 fitting to the experimental cumulative runoff data; (ii) estimating solely on soil texture; and (iii) estimating by individual pedotransfer functions (PTFs) and an ensemble of PTFs from basic soil properties. Results show that the most accurate prediction was obtained when the G parameter was fitted to the cumulative runoff. The KINEROS2-recommended parameter slightly overestimated the calibrated value of parameter G and yielded less accurate predictions of runoff, FC concentrations and total FC. The PTFs-estimated parameters systematically deviated from calibrated G values that caused high uncertainty in the KINEROS2/STWIR predictions. Averaging PTF estimates considerably improved model accuracy, reducing the uncertainty of runoff and FC concentration predictions. Overall, ensemble-based PTF estimation of the capillary drive can be efficient for simulations of runoff and bacteria overland transport when a single effective value is used across the study area.

TI Successional changes in the chicken cecal microbiome during 42 days of growth are independent of organic acid feed additives SO BMC VETERINARY RESEARCH LA English DT Article ID INTESTINAL BACTERIAL COMMUNITY; BROILER-CHICKENS; GASTROINTESTINAL-TRACT; GUT MICROBIOME; CLOSTRIDIUM-PERFRINGENS; INDIGENOUS BACTERIA; FOODBORNE ILLNESS; FECAL MICROBIOTA; GENOME SEQUENCE; UNITED-STATES AB Background: Poultry remains a major source of foodborne bacterial infections. A variety of additives with presumed anti-microbial and/or growth-promoting effects are commonly added to poultry feed during commercial grow-out, yet the effects of these additives on the gastrointestinal microbial community (the GI microbiome) as the bird matures remain largely unknown. Here we compared temporal changes in the cecal microbiome to the effects of formic acid, propionic acid, and medium-chain fatty acids (MCFA) added to feed and/or drinking water. Results: Cecal bacterial communities at day of hatch (n = 5 birds), 7d (n = 32), 21d (n = 27), and 42d (n = 36) post-hatch were surveyed using direct 454 sequencing of 16S rRNA gene amplicons from each bird in combination with cultivation-based recovery of a Salmonella Typhimurium marker strain and quantitative-PCR targeting Clostridium perfringens. Treatment effects on specific pathogens were generally non-significant. S. Typhimurium introduced by oral gavage at day of hatch was recovered by cultivation from nearly all birds sampled across treatments at 7d and 21d, but by 42d, S. Typhimurium was only recovered from ca. 25% of birds, regardless of treatment. Sequencing data also revealed non-significant treatment effects on genera containing known pathogens and on the cecal microbiome as a whole. In contrast, temporal changes in the cecal microbiome were dramatic, highly significant, and consistent across treatments. At 7d, the cecal community was dominated by three genera (Flavonifractor, Pseudoflavonifractor, and a Lachnospiracea sequence type) that accounted for more than half of sequences. By 21d post-hatch, a single genus (Faecalibacterium) accounted for 23-55% of sequences, and the number of Clostridium 16S rRNA gene copies detected by quantitative-PCR reached a maximum. Conclusions: Over the 42 d experiment, the cecal bacterial community changed significantly as measured by a variety of ecological metrics and increases in the complexity of co-occurrence networks. Management of poultry to improve animal health, nutrition, or food safety may need to consider the interactive effects of any treatments with the dramatic temporal shifts in the taxonomic composition of the cecal microbiome as described here.

TI Multi-scale streambed topographic and discharge effects on hyporheic exchange at the stream network scale in confined streams SO JOURNAL OF HYDROLOGY LA English DT Article DE Hyporheic exchange; Wavelet analysis; Streambed morphology; Confined streams ID SEDIMENT-WATER INTERFACE; BED FORMS; NONSORBING SOLUTES; LOWLAND STREAMS; THERMAL REGIME; ZONE; IMPACT; FLOW; TRANSPORT; MODEL AB The hyporheic zone is the volume of the streambed sediment mostly saturated with stream water. It is the transitional zone between stream and shallow-ground waters and an important ecotone for benthic species, including macro-invertebrates, microorganisms, and some fish species that dwell in the hyporheic zone for parts of their lives. Most hyporheic analyses are limited in scope, performed at the reach scale with hyporheic exchange mainly driven by one mechanism, such as interaction between flow and ripples or dunes. This research investigates hyporheic flow induced by the interaction of flow and streambed topography at the valley-scale under different discharges. We apply a pumping based hyporheic model along a 37 km long reach of the Deadwood River for different flow releases from Deadwood Reservoir and at different discharges of its tributaries. We account for dynamic head variations, induced by interactions of small-scale topography and flow, and piezometric head variations, caused by reach-scale bathymetry-flow interactions. We model the dynamic head variations as those caused by dune-like bedforms and piezometric heads with the water surface elevation predicted with a 1-dimensional, 1D, hydraulic model supported by close-spaced cross-sections extracted every channel width from high-resolution bathymetry. Superposition of these two energy-head components provides the boundary condition at the water-sediment interface for the hyporheic model. Our results show that small- and large-scale streambed features induce fluxes of comparable magnitude but the former and the latter dominate fluxes with short and long residence times, respectively. In our setting, stream discharge and alluvium thickness have limited effects on hyporheic processes including the thermal regime of the hyporheic zone. Bed topography is a strong predictor of hyporheic exchange and the 10 wavelet is a convenient way to describe the bed topography quantitatively. Thus wavelet power could be a good index for hyporheic potential, with areas of high and low wavelet power coinciding with high and low hyporheic fluxes, respectively. (C) 2014 Elsevier B.V.

Q(eff) may approach bankfull flow in some step-pool channels where gravel moves over a static cobble/boulder bed. Our conclusions are based on magnitude-frequency analyses conducted at 41 gauged Rocky Mountain headwater streams. Because these gauged streams lacked gravel transport data, as is typical, comparable streams with measured transport rates were used to develop scaling relations for rating curve exponents with stream and watershed characteristics. Those scaling relations were then used to estimate the steepness of gravel rating curves at the 41 gauged but unsampled sites. The measured flow frequency distributions were characterized by two fitted power functions. The steepness of the flow frequency distributions and the estimated steepness of gravel transport relations were combined in magnitude-frequency analyses to compute Q(eff). (C) 2014 Elsevier B.V.

Here we examined the mechanism of resistance to Bt toxin Cry1Ac in the laboratory-selected LF5 strain of the cotton bollworm, Helicoverpa armigera. This strain had 110-fold resistance to Cry1Ac protoxin and 39-fold resistance to Cry1Ac activated toxin. Evaluation of five trypsin genes revealed 99% reduced transcription of one trypsin gene (HaTryR) was associated with resistance. Silencing of this gene with RNA interference in susceptible larvae increased their survival on diets containing Cry1Ac. Bioassays of progeny from crosses revealed that resistance to Cry1Ac was genetically linked with HaTryR. We identified mutations in the promoter region of HaTryR in the resistant strain. In transfected insect cell lines, transcription was lower when driven by the resistant promoter compared with the susceptible promoter, implicating cis-mediated down-regulation of HaTryR transcription as a mechanism of resistance. The results suggest that H. armigera can adapt to Bt toxin Cry1Ac by decreased expression of trypsin. Because trypsin activation of protoxin is a critical step in toxicity, transgenic plants with activated toxins rather than protoxins might increase the durability of Bt crops.

Several previous studies reported inconsistent results on the role of exogenous IL-25 in development of colonic inflammation and none were performed in animals with a genetic deletion of IL-25. We investigated the contribution of endogenous IL-25 to DSS-induced colitis using mice deficient in IL-25. Results: Mice were exposed to DSS in drinking water ad libitum either for seven days (acute) or for three cycles of seven days with DSS followed by 14 days without DSS (chronic) to induce colitis, respectively. The loss of body weight, appearance of diarrhea and bloody stools, and shortening of colon length were significantly less pronounced in IL-25(-/-) mice compared to WT mice after exposure to acute DSS. Histological examination showed that DSS-treated IL-25(-/-) mice had only mild inflammation in the colon, while severe inflammation developed in DSS-treated WT mice. A significant up-regulation of IL-33 was observed in acute DSS-treated WT but not in the IL-25(-/-) mice. There was significantly lower expression of pro-inflammatory cytokines in the colon of acute DSS-treated IL-25(-/-) compared to WT mice. IL-25(-/-) mice were also partially protected from chronic DSS challenge especially during the first 2 cycles of DSS exposure. In contrast to IL-25(-/-) mice, IL-13(-/-) mice were more susceptible to DSS-induced colitis. Finally, stimulation of T84 colonic epithelial cells with IL-25 up-regulated the expression of IL-33 and several pro-inflammatory cytokines. Conclusions: These data indicate that endogenous IL-25 acts as a pro-inflammatory factor in DSS-induced colitis, which is unlikely to be mediated by IL-13 but possibly the induction of IL-33 and other pro-inflammatory mediators from colonic epithelial cells. The present study suggests that IL-25 may contribute to the pathogenesis of inflammatory bowel disease in at least a subgroup of patients.

Its seed oil is rich in omega-3 fatty acids, such as stearidonic acid, which is desired highly by the cosmetic industry. Seeds were sown in field plots over three years in western Minnesota in spring (early-sown) or early summer (late-sown), and flower abundance, pollinator visitation, and seed yields were studied. Initial flowering commenced 41 to 55 d after sowing, and anthesis duration (first flowering to harvest) was 34 to 70 d. Late sowing dates delayed anthesis, but increased the intensity of visitation by pollinators. Cumulative flower densities ranged from 1 to 4.5 billion ha(-1). Flowers attracted numerous honey bees (Apis mellifera L.), as many as 35 per minute of observation, which represented about 50% of all insect visitors. Early-sown echium produced seed yields up to 750 kg ha(-1), which were 2-29 times higher than those of late-sown echium. Early sowing of echium in Minnesota provides abundant floral resources for pollinators for up to two months and simultaneously produces seed yields whose profits rival those of corn (Zea mays L.).

Herein we describe results from the initial study identifying abundant ginkgo leaf proteins and present a gel reference map. Proteins were isolated from fully developed mature leaves in biological triplicate and analyzed by two-dimensional electrophoresis plus tandem mass spectrometry. Using this approach, we were able to reproducibly quantify 190 abundant protein spots, from which 157 proteins were identified. Most of identified proteins are associated with the energy and protein destination/storage categories. The reference map provides a basis for understanding the accumulation of flavonoids and other phenolic compounds in mature leaves (e.g., identification of chalcone synthase, the first committed enzyme in flavonoid biosynthesis). We additionally detected several proteins of as yet unknown function. These proteins comprise a pool of potential targets that might be useful in nontraditional medical applications.

TI Regulatory interplay between soybean root and soybean cyst nematode during a resistant and susceptible reaction SO BMC PLANT BIOLOGY LA English DT Article DE Soybean; Soybean cyst nematode; SCN; Transcription factor binding site ID GENE-EXPRESSION; HETERODERA-GLYCINES; TRANSCRIPTION FACTORS; SIGNAL-TRANSDUCTION; DEFENSE RESPONSES; OXIDATIVE STRESS; FEEDING CELLS; KNOT NEMATODE; JASMONIC ACID; BIOTIC STRESS AB Background: Plant-parasitic nematodes (PPNs) are obligate parasites that feed on the roots of living host plants. Often, these nematodes can lay hundreds of eggs, each capable of surviving without a host for as long as 12 years. When it comes to wreaking havoc on agricultural yield, few nematodes can compare to the soybean cyst nematode (SCN). Quantifying soybean (Glycinemax) transcription factor binding sites (TFBSs) during a late-stage SCN resistant and susceptible reaction can shed light onto the systematic interplay between host and pathogen, thereby elucidating underlying cis-regulatory mechanisms. Results: We sequenced the soybean root transcriptome at 6 and 8 days upon independent inoculation with a virulent and avirulent SCN population. Genes such as beta-1,4 glucanase, chalcone synthase, superoxide dismutase and various heat shock proteins (HSPs) exhibited reaction-specific expression profiles. Several likely defense-response genes candidates were also identified which are believed to confer SCN resistance. To explore magnitude of TFBS representation during SCN pathogenesis, a multivariate statistical software identified 46 over-represented TFBSs which capture soybean regulatory dynamics across both reactions. Conclusions: Our results reveal a set of soybean TFBSs which are over-represented solely throughout a resistant and susceptible SCN reaction. This set furthers our understanding of soybean cis-regulatory dynamics by providing reaction-specific levels of over-representation at 6 and 8 days after inoculation (dai) with SCN.

TI Genome-wide candidate regions for selective sweeps revealed through massive parallel sequencing of DNA across ten turkey populations SO BMC GENETICS LA English DT Article ID BODY-COMPOSITION; MELEAGRIS-GALLOPAVO; METABOLIC TRAITS; INITIAL SEQUENCE; CHICKEN LINES; AVIAN GENOME; GROWTH; DISCOVERY; CATTLE; LOCI AB Background: The domestic turkey (Meleagris gallopavo) is an important agricultural species that is largely used as a meat-type bird. Characterizing genetic variation in populations of domesticated species and associating these variation patterns with the evolution, domestication, and selective breeding is critical for understanding the dynamics of genomic change in these species. Intense selective breeding and population bottlenecks are expected to leave signatures in the genome of domesticated species, such as unusually low nucleotide diversity or the presence of exceptionally extended haplotype homozygosity. These patterns of variation in selected populations are highly useful to not only understand the consequences of selective breeding and population dynamics, but also to provide insights into biological mechanisms that may affect physiological processes important to bring changes in phenotype of interest. Results: We observed 54 genomic regions in heritage and commercial turkey populations on 14 different chromosomes that showed statistically significant (P < 0.05) reduction in genomic variation indicating candidate selective sweeps. Areas with evidence of selective sweeps varied from 1.5 Mb to 13.8 Mb in length. Out of these 54 sweeps, 23 overlapped at least partially between two or more populations. Overlapping sweeps were found on 13 different chromosomes. The remaining 31 sweeps were population-specific and were observed on 12 different chromosomes, with 26 of these regions present only in commercial populations. Genes that are known to affect growth were enriched in the sweep regions. Conclusion: The turkey genome showed large sweep regions. The relatively high number of sweep regions in commercial turkey populations compared to heritage varieties and the enrichment of genes important to growth in these regions, suggest that these sweeps are the result of intense selection in these commercial lines, moving specific haplotypes towards fixation.

TI Isotopically nonstationary C-13 flux analysis of changes in Arabidopsis thaliana leaf metabolism due to high light acclimation SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE isotopomer modeling; metabolic flux analysis; photosynthesis; C-13-labeling; primary metabolism ID C-3 PLANTS; CARBON METABOLISM; MASS-SPECTROMETRY; BALANCE ANALYSIS; PHOTOSYNTHESIS; PHOTORESPIRATION; LEAVES; (CO2)-C-13; REVEALS; ENZYMES AB Improving plant productivity is an important aim for metabolic engineering. There are few comprehensive methods that quantitatively describe leaf metabolism, although such information would be valuable for increasing photosynthetic capacity, enhancing biomass production, and rerouting carbon flux toward desirable end products. Isotopically nonstationary metabolic flux analysis (INST-MFA) has been previously applied to map carbon fluxes in photoautotrophic bacteria, which involves model-based regression of transient C-13-labeling patterns of intracellular metabolites. However, experimental and computational difficulties have hindered its application to terrestrial plant systems. We performed in vivo isotopic labeling of Arabidopsis thaliana rosettes with (CO2)-C-13 and estimated fluxes throughout leaf photosynthetic metabolism by INST-MFA. Plants grown at 200 mu mol m(-2)s(-1) light were compared with plants acclimated for 9 d at an irradiance of 500 mu mol.m(-2).s(-1). Approximately 1,400 independent mass isotopomer measurements obtained from analysis of 37 metabolite fragment ions were regressed to estimate 136 total fluxes (54 free fluxes) under each condition. The results provide a comprehensive description of changes in carbon partitioning and overall photosynthetic flux after long-term developmental acclimation of leaves to high light. Despite a doubling in the carboxylation rate, the photorespiratory flux increased from 17 to 28% of net CO2 assimilation with high-light acclimation (Vc/Vo: 3.5:1 vs. 2.3:1, respectively). This study highlights the potential of C-13 INST-MFA to describe emergent flux phenotypes that respond to environmental conditions or plant physiology and cannot be obtained by other complementary approaches.

TI Genetic Insights into Graminella nigrifrons Competence for Maize fine streak virus Infection and Transmission SO PLOS ONE LA English DT Article ID VESICULAR STOMATITIS-VIRUS; YELLOW NET VIRUS; MOSAIC-VIRUS; PEREGRINUS-MAIDIS; INSECT VECTOR; INTRACELLULAR-TRANSPORT; TRANSMITTED VIRUSES; POPULATION-GENETICS; MOVEMENT PROTEIN; INNATE IMMUNITY AB Background: Most plant-infecting rhabdoviruses are transmitted by one or a few closely related insect species. Additionally, intraspecific differences in transmission efficacy often exist among races/biotypes within vector species and among strains within a virus species. The black-faced leafhopper, Graminella nigrifrons, is the only known vector of the persistent propagative rhabdovirus Maize fine streak virus (MFSV). Only a small percentage of leafhoppers are capable of transmitting the virus, although the mechanisms underlying vector competence are not well understood. Methodology: RNA-Seq was carried out to explore transcript expression changes and sequence variation in G. nigrifrons and MFSV that may be associated with the ability of the vector to acquire and transmit the virus. RT-qPCR assays were used to validate differential transcript accumulation. Results/Significance: Feeding on MFSV-infected maize elicited a considerable transcriptional response in G. nigrifrons, with increased expression of cytoskeleton organization and immunity transcripts in infected leafhoppers. Differences between leafhoppers capable of transmitting MFSV, relative to non-transmitting but infected leafhoppers were more limited, which may reflect difficulties discerning between the two groups and/or the likelihood that the transmitter phenotype results from one or few genetic differences. The ability of infected leafhoppers to transmit MFSV did not appear associated with virus transcript accumulation in the infected leafhoppers or sequence polymorphisms in the viral genome. However, the non-structural MFSV 3 gene was expressed at unexpectedly high levels in infected leafhoppers, suggesting it plays an active role in the infection of the insect host. The results of this study begin to define the functional roles of specific G. nigrifrons and MFSV genes in the viral transmission process.

Tropical cattle production, a mainstay of profitability for farmers in the developing world, is dominated by heat, lack of water, poor quality feedstuffs, parasites, and tropical diseases. In these systems European cattle suffer significant stock loss, and the cross breeding of taurine x indicine cattle is unpredictable due to the dilution of adaptation to heat and tropical diseases. We explored the genetic architecture of ten traits of tropical cattle production using genome wide association studies of 4,662 animals varying from 0% to 100% indicine. We show that nine of the ten have genetic architectures that include genes of major effect, and in one case, a single location that accounted for more than 71% of the genetic variation. One genetic region in particular had effects on parasite resistance, yearling weight, body condition score, coat colour and penile sheath score. This region, extending 20 Mb on BTA5, appeared to be under genetic selection possibly through maintenance of haplotypes by breeders. We found that the amount of genetic variation and the genetic correlations between traits did not depend upon the degree of indicine content in the animals. Climate change is expected to expand some conditions of the tropics to more temperate environments, which may impact negatively on global livestock health and production. Our results point to several important genes that have large effects on adaptation that could be introduced into more temperate cattle without detrimental effects on productivity.

The aim of this study was to develop molecular tools for assessing genetic diversity and provide unique molecular identification of C mas samples from central Europe and United States. A microsatellite-enriched library was used to develop nine polymorphic microsatellite loci. The loci amplified perfect and imperfect repeats with 2 to 11 alleles detected per locus. Observed heterozygosity ranged from 0.00 to 0.71 and expected heterozygosity ranged from 0.00 to 0.82. Additionally, cross species transfer to Cornus eydeana was observed. The multilocus allelic data was used to cluster 37 C. mas samples and 1 C eydeana sample based on the allele sharing distance matrix. The similarity coefficient ranged from 0.05 to 0.73 among all genotypes. All C mas individuals clustered into two main clades, with the single C. eydeana sample used to root the dendrogram. All samples in group I belong to the botanical form Macrocarpa and originated from Austria, Poland, or Ukraine, whereas group II included samples that originated from Poland, Romania, and the United States. Five loci (CM007, CM010, CM031, CM037, and CM043) were used to develop a molecular identification key that successfully delineated all samples. The loci described in this study will facilitate further investigations of genetic diversity, gene flow, and genetic structure among populations of C. mas. (C) 2014 Elsevier B.V. All rights reserved.

We summarize the proposed changes in the classification since the end of 1978. We propose revised status for two genera, Rolandylis Gibeaux, 1985 and Thyraylia Walsingham, 1897. We propose eleven revised combinations: Saphenista parvimaculana (Walsingham, 1879), unplaced Cochylina omphacitis (Meyrick, 1912) [Cochylis], unplaced Cochylina voxcana (Kearfott, 1907) [Phalonia], Thyraylia bana (Kearfott, 1907), Thyraylia rhodites (Meyrick, 1912), Thyraylia bunteana (Robinson, 1869), Thyraylia discana (Kearfott, 1907), Thyraylia cricota (Meyrick, 1912), Thyraylia gunniana (Busck, 1907), Thyraylia hollandana (Kearfott, 1907), and Thyraylia none (Haworth, [1811]). We propose four revised combinations: Rolandylis fusca Pogue, 2001, Rolandylis maiana (Kearfott, 1907), Rolandylis catalonica Gibeaux, 1985, Rolandylis virilia Pogue, 2001; and three new synonymies: Aethes cane Kearfott with A. bomonana (Kearfott), Henricus edwarsiana (Walsingham) with H. contrastana (Kearfott), and Phtheochroa pecosana (Kearfott, 1907) with Phtheochroa cartwrightana (Kearfott, 1907). The described fauna includes 20 genera and 137 species, yet it is likely that this region of North America includes two to three times that many species; at least six new genera are defined, but not yet formally described.

TI QTLs associated with dry matter intake, metabolic mid-test weight, growth and feed efficiency have little overlap across 4 beef cattle studies SO BMC GENOMICS LA English DT Article DE GWAS; QTL; Genomic selection; Feed efficiency; Beef cattle ID GENOME-WIDE ASSOCIATION; QUANTITATIVE TRAIT LOCI; DAIRY-CATTLE; BREEDING VALUES; LINKAGE DISEQUILIBRIUM; MILK-PRODUCTION; FARM-ANIMALS; ANGUS CATTLE; FOOD-INTAKE; CYCLIN D2 AB Background: The identification of genetic markers associated with complex traits that are expensive to record such as feed intake or feed efficiency would allow these traits to be included in selection programs. To identify large-effect QTL, we performed a series of genome-wide association studies and functional analyses using 50 K and 770 K SNP genotypes scored in 5,133 animals from 4 independent beef cattle populations (Cycle VII, Angus, Hereford and Simmental x Angus) with phenotypes for average daily gain, dry matter intake, metabolic mid-test body weight and residual feed intake. Results: A total of 5, 6, 11 and 10 significant QTL (defined as 1-Mb genome windows with Bonferroni-corrected P-value <0.05) were identified for average daily gain, dry matter intake, metabolic mid-test body weight and residual feed intake, respectively. The identified QTL were population-specific and had little overlap across the 4 populations. The pleiotropic or closely linked QTL on BTA 7 at 23 Mb identified in the Angus population harbours a promising candidate gene ACSL6 (acyl-CoA synthetase long-chain family member 6), and was the largest effect QTL associated with dry matter intake and mid-test body weight explaining 10.39% and 14.25% of the additive genetic variance, respectively. Pleiotropic or closely linked QTL associated with average daily gain and mid-test body weight were detected on BTA 6 at 38 Mb and BTA 7 at 93 Mb confirming previous reports. No QTL for residual feed intake explained more than 2.5% of the additive genetic variance in any population. Marker-based estimates of heritability ranged from 0.21 to 0.49 for residual feed intake across the 4 populations. Conclusions: This GWAS study, which is the largest performed for feed efficiency and its component traits in beef cattle to date, identified several large-effect QTL that cumulatively explained a significant percentage of additive genetic variance within each population. Differences in the QTL identified among the different populations may be due to differences in power to detect QTL, environmental variation, or differences in the genetic architecture of trait variation among breeds. These results enhance our understanding of the biology of growth, feed intake and utilisation in beef cattle.

Barkworth & D. R. Dewey are important intermediates in wheat breeding because of their resistance to major wheat diseases. In this study, we examined the chromosome compositions of five Xiaoyan-series wheat-Th. ponticum partial amphiploids (Xiaoyan 68, Xiaoyan 693, Xiaoyan 784, Xiaoyan 7430, and Xiaoyan 7631) using GISH, multicolor-GISH, and multicolor-FISH. We found several chromosome changes in these lines. For example, wheat chromosomes 1B and 2B were added in Xiaoyan 68 and Xiaoyan 7430, respectively, while wheat chromosome 6B was eliminated from Xiaoyan 693 and Xiaoyan 7631. Chromosome rearrangements were also detected in these amphiploids, including an interspecific translocation involving chromosome 4D and some intergenomic translocations, such as AeB and AeD translocations, among wheat genomes. Analysis of the Th. ponticum chromosomes in the amphiploids showed that some lines shared the same alien chromosomes. We also evaluated these partial amphiploids for resistance to nine races of stem rust, including TTKSK (commonly known as Ug99). Three lines, Xiaoyan 68, Xiaoyan 784, and Xiaoyan 7430, exhibited excellent resistance to all nine races, and could therefore be valuable sources of stem rust resistance in wheat breeding.

TI Esterase in Imported Fire Ants, Solenopsis invicta and S. richteri (Hymenoptera: Formicidae): Activity, Kinetics and Variation SO SCIENTIFIC REPORTS LA English DT Article ID INSECTICIDE RESISTANCE; DIPTERA-CULICIDAE; POPULATIONS; INVASION; CARBOXYLESTERASE; 2-TRIDECANONE; SECRETIONS; TOLERANCE; CHEMISTRY; HEMIPTERA AB Solenopsis invicta and Solenopsis richteri are two closely related invasive ants native to South America. Despite their similarity in biology and behavior, S. invicta is a more successful invasive species. Toxic tolerance has been found to be important to the success of some invasive species. Esterases play a crucial role in toxic tolerance of insects. Hence, we hypothesized that the more invasive S. invicta would have a higher esterase activity than S. richteri. Esterase activities were measured for workers and male and female alates of both ant species using alpha-naphthyl acetate and beta-naphthyl acetate as substrates. Esterase activities in S. invicta were always significantly higher than those in S. richteri supporting our hypothesis. In S. invicta, male alates had the highest esterase activities followed by workers then female alates for both substrates. In S. richetri, for alpha-naphthyl acetate, male alates had the highest activity followed by female alates then workers, while for beta-naphthyl acetate, female alates had the highest activity followed by male alates then workers. For workers, S. richteri showed significantly higher levels of variation about the mean esterase activity than S. invicta. However, S. invicta showed significantly higher levels of variation in both female and male alates. C1 [Chen, J.] USDA ARS, Southeast Area, Natl Biol Control Lab, Stoneville, MS 38776 USA.

TI Development of an OP9 Derived Cell Line as a Robust Model to Rapidly Study Adipocyte Differentiation SO PLOS ONE LA English DT Article ID ADIPOGENIC DIFFERENTIATION; CARDIOVASCULAR-DISEASE; GENE-EXPRESSION; 3T3-L1 CELLS; RISK-FACTORS; PPAR-GAMMA; STEM-CELLS; IN-VITRO; ADIPOSE; OBESITY AB One hallmark of obesity is adipocyte hypertrophy and hyperplasia. To gain novel insights into adipose biology and therapeutics, there is a pressing need for a robust, rapid, and informative cell model of adipocyte differentiation for potential RNAi and drug screens. Current models are prohibitive for drug and RNAi screens due to a slow differentiation time course and resistance to transfection. We asked if we could create a rapid, robust model of adipogenesis to potentially enable rapid functional and obesity therapeutic screens. We generated the clonal population OP9-K, which differentiates rapidly and reproducibly, and displays classic adipocyte morphology: rounded cell shape, lipid accumulation, and coalescence of lipids into a large droplet. We further validate the OP9-K cells as an adipocyte model system by microarray analysis of the differentiating transcriptome. OP9-K differentiates via known adipogenic pathways, involving the transcriptional activation and repression of common adipose markers Plin1, Gata2, C/Ebp alpha and C/Ebp beta and biological pathways, such as lipid metabolism, PPAR gamma signaling, and osteogenesis. We implemented a method to quantify lipid accumulation using automated microscopy and tested the ability of our model to detect alterations in lipid accumulation by reducing levels of the known master adipogenic regulator Ppar gamma. We further utilized our model to query the effects of a novel obesity therapeutic target, the transcription factor SPI1. We determine that reduction in levels of Spi1 leads to an increase in lipid accumulation. We demonstrate rapid, robust differentiation and efficient transfectability of the OP9-K cell model of adipogenesis. Together with our microscopy based lipid accumulation assay, adipogenesis assays can be achieved in just four days' time. The results of this study can contribute to the development of rapid screens with the potential to deepen our understanding of adipose biology and efficiently test obesity therapeutics.

TI The Genome of the Generalist Plant Pathogen Fusarium avenaceum Is Enriched with Genes Involved in Redox, Signaling and Secondary Metabolism SO PLOS ONE LA English DT Article ID POLYKETIDE SYNTHASE GENES; MATING-TYPE; MYCOTOXIN PRODUCTION; GIBBERELLA-ZEAE; FUNCTIONAL-CHARACTERIZATION; BIOSYNTHETIC-PATHWAY; CYCLIC TETRAPEPTIDE; DRY ROT; ZEARALENONE; FUNGUS AB Fusarium avenaceum is a fungus commonly isolated from soil and associated with a wide range of host plants. We present here three genome sequences of F. avenaceum, one isolated from barley in Finland and two from spring and winter wheat in Canada. The sizes of the three genomes range from 41.6-43.1 MB, with 13217-13445 predicted protein-coding genes. Whole-genome analysis showed that the three genomes are highly syntenic, and share>95% gene orthologs. Comparative analysis to other sequenced Fusaria shows that F. avenaceum has a very large potential for producing secondary metabolites, with between 75 and 80 key enzymes belonging to the polyketide, non-ribosomal peptide, terpene, alkaloid and indole-diterpene synthase classes. In addition to known metabolites from F. avenaceum, fuscofusarin and JM-47 were detected for the first time in this species. Many protein families are expanded in F. avenaceum, such as transcription factors, and proteins involved in redox reactions and signal transduction, suggesting evolutionary adaptation to a diverse and cosmopolitan ecology. We found that 20% of all predicted proteins were considered to be secreted, supporting a life in the extracellular space during interaction with plant hosts.

TI Chemotaxonomy of Hawaiian Anthurium Cultivars Based on Multivariate Analysis of Phenolic Metabolites SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE Anthurium; chemotaxonomy; flavonoid; metabolomics; HPLC-MS ID SPATHE COLOR; MASS-SPECTROMETRY; ANDRAEANUM HORT.; ANTHOCYANINS; INHERITANCE; FLAVONOIDS; PROFILES; ARACEAE; GENES AB Thirty-six anthurium varieties, sampled from species and commercial cultivars, were extracted and profiled by liquid-chromatography-mass spectrometry (HPLC-MS). Three hundred fifteen compounds, including anthocyanins, flavonoid glycosides, and other phenolics, were detected from these extracts and used in chemotaxonomic analysis of the specimens. Hierarchical duster analysis (HCA) revealed close chemical similarities between all the commercial standard cultivars, while tulip-shaped ctiltivars and species displayed much greater chemical variation. Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) supported the results from HCA and were used to identify key metabolites characteristic of standard and tulip cultivars and to identify chemical markers indicative of a particular ancestry. Discriminating metabolites included embinin, 4, which was characteristic of standard-shaped spathes and indicated ancestry from Anthurium andraeanum, while isocytisoside 7-glucoside, 7, was found in the majority of tulip-shaped cultivars and suggested that Anthurium amnicola or Anthurium antioquiense had contributed to their pedigree.

TI Genome-wide analysis of the omega-3 fatty acid desaturase gene family in Gossypium SO BMC PLANT BIOLOGY LA English DT Article DE Chilling tolerance; Cotton; Drought; Fatty acid desaturase; Gossypium; Linolenic acid; Omega-3 fatty acid ID FATTY-ACID DESATURATION; MULTIPLE SEQUENCE ALIGNMENT; TRANSGENIC TOBACCO; COTTON SEEDLINGS; LOW-TEMPERATURE; COLD TOLERANCE; ALLOPOLYPLOID COTTON; ARABIDOPSIS-THALIANA; MAXIMUM-LIKELIHOOD; OMEGA-3 DESATURASE AB Background: The majority of commercial cotton varieties planted worldwide are derived from Gossypium hirsutum, which is a naturally occurring allotetraploid produced by interspecific hybridization of A-and D-genome diploid progenitor species. While most cotton species are adapted to warm, semi-arid tropical and subtropical regions, and thus perform well in these geographical areas, cotton seedlings are sensitive to cold temperature, which can significantly reduce crop yields. One of the common biochemical responses of plants to cold temperatures is an increase in omega-3 fatty acids, which protects cellular function by maintaining membrane integrity. The purpose of our study was to identify and characterize the omega-3 fatty acid desaturase (FAD) gene family in G. hirsutum, with an emphasis on identifying omega-3 FADs involved in cold temperature adaptation. Results: Eleven omega-3 FAD genes were identified in G. hirsutum, and characterization of the gene family in extant A and D diploid species (G. herbaceum and G. raimondii, respectively) allowed for unambiguous genome assignment of all homoeologs in tetraploid G. hirsutum. The omega-3 FAD family of cotton includes five distinct genes, two of which encode endoplasmic reticulum-type enzymes (FAD3-1 and FAD3-2) and three that encode chloroplast-type enzymes (FAD7/8-1, FAD7/8-2, and FAD7/8-3). The FAD3-2 gene was duplicated in the A genome progenitor species after the evolutionary split from the D progenitor, but before the interspecific hybridization event that gave rise to modern tetraploid cotton. RNA-seq analysis revealed conserved, gene-specific expression patterns in various organs and cell types and semi-quantitative RT-PCR further revealed that FAD7/8-1 was specifically induced during cold temperature treatment of G. hirsutum seedlings. Conclusions: The omega-3 FAD gene family in cotton was characterized at the genome-wide level in three species, showing relatively ancient establishment of the gene family prior to the split of A and D diploid progenitor species. The FAD genes are differentially expressed in various organs and cell types, including fiber, and expression of the FAD7/8-1 gene was induced by cold temperature. Collectively, these data define the genetic and functional genomic properties of this important gene family in cotton and provide a foundation for future efforts to improve cotton abiotic stress tolerance through molecular breeding approaches.

TI Fitting a Distribution to Censored Contamination Data Using Markov Chain Monte Carlo Methods and Samples Selected with Unequal Probabilities SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID PROBABLE NUMBER DATA; RISK-ASSESSMENT; SALMONELLA; STATISTICS; POPULATIONS; PREVALENCE; POULTRY AB The fitting of statistical distributions to chemical and microbial contamination data is a common application in risk assessment. These distributions are used to make inferences regarding even the most pedestrian of statistics, such as the population mean. The reason for the heavy reliance on a fitted distribution is the presence of left-, right-, and interval-censored observations in the data sets, with censored observations being the result of nondetects in an assay, the use of screening tests, and other practical limitations. Considerable effort has been expended to develop statistical distributions and fitting techniques for a wide variety of applications. Of the various fitting methods, Markov Chain Monte Carlo methods are common. An underlying assumption for many of the proposed Markov Chain Monte Carlo methods is that the data represent independent and identically distributed (iid) observations from an assumed distribution. This condition is satisfied when samples are collected using a simple random sampling design. Unfortunately, samples of food commodities are generally not collected in accordance with a strict probability design. Nevertheless, pseudosystematic sampling efforts (e.g., collection of a sample hourly or weekly) from a single location in the farm-to-table continuum are reasonable approximations of a simple random sample. The assumption that the data represent an iid sample from a single distribution is more difficult to defend if samples are collected at multiple locations in the farm-to-table continuum or risk-based sampling methods are employed to preferentially select samples that are more likely to be contaminated. This paper develops a weighted bootstrap estimation framework that is appropriate for fitting a distribution to microbiological samples that are collected with unequal probabilities of selection. An example based on microbial data, derived by the Most Probable Number technique, demonstrates the method and highlights the magnitude of biases in an estimator that ignores the effects of an unequal probability sample design.

TI Functionalized graphenes with polymer toughener as novel interface modifier for property-tailored polylactic acid/graphene nanocomposites SO POLYMER LA English DT Article DE Functionalized graphene; Interfacial modifier; Polylactic acid nanocomposites ID GRAPHITE OXIDE; ELECTRICAL-CONDUCTIVITY; LINEAR VISCOELASTICITY; DISPERSIBLE GRAPHENE; POLY(LACTIC ACID); REDUCTION; RHEOLOGY; BLENDS; COMPOSITES; SPECTROSCOPY AB In this work, an effective strategy for engineering the interfacial compatibility between graphene and polylactic acid (PLA) was developed by manipulating the functionalization of graphene and introducing an epoxy-containing elastomer modifier. Curing between the functional groups of the modified graphene and the epoxy groups of the elastomer modifier resulted in controlled dispersion and distribution of graphene in the composite system and hence improved the interfacial adhesion between PLA and graphene. Effects of different graphene functionalization with polymer toughener on morphology, viscoelasticity, and thermal properties of the resulting PLA nanocomposites were thoroughly examined. The resulting percolated structures were the origin of the improved properties of PLA/graphene nanocomposites. The mechanism on property tailoring from interface engineering through dual modifiers are also proposed. Overall, the insight into the interface engineering between the functionalized graphene and the matrix through an elastomer modifier offers a novel way for the future design of graphene polymer nanocomposites.

Atmospheric nitrogen deposition often greatly exceeds streamwater nitrogen losses; the fate of the remaining nitrogen is highly uncertain. Gaseous losses of nitrogen to denitrification are especially poorly documented and are often ignored. Here, we provide isotopic evidence (delta N-15(NO3) and delta O-18(NO3)) from shallow groundwater at the Hubbard Brook Experimental Forest indicating extensive denitrification during midsummer, when transient, perched patches of saturation developed in hillslopes, with poor hydrological connectivity to the stream, while streamwater showed no isotopic evidence of denitrification. During small rain events, precipitation directly contributed up to 34% of streamwater nitrate, which was otherwise produced by nitrification. Together, these measurements reveal the importance of denitrification in hydrologically disconnected patches of shallow groundwater during midsummer as largely overlooked control points for nitrogen loss from temperate forest catchments.

Single-particle catalysis of a modular multilayer catalytic platform that consists of a solid silica core, a mesoporous silica shell, and uniformly distributed Pt nanoparticles sandwiched in between these layers is presented. The first 3D high-resolution super-localization imaging of single fluorescent molecules produced at active sites on the core-shell model nanocatalysts is demonstrated. The 3D mapping is aided by the well-defined geometry and a correlation study in scanning electron microscopy and total internal reflection fluorescence and scattering microscopy. This approach can be generalized to study other nano- and mesoscale structures.

However, field resistance related to the reduced efficacy of Bt maize has not been documented in any lepidopteran pest in the mainland U. S. after 18 years of intensive Bt maize planting. Here we report compelling evidence of field resistance in the fall armyworm, Spodoptera frugiperda (J.E. Smith), to Cry1F maize (TC 3507) in the southeastern region of the U. S. An F-2 screen showed a surprisingly high (0.293) Cry1F resistance allele frequency in a population collected in 2011 from non-Bt maize in south Florida. Field populations from non-Bt maize in 2012-2013 exhibited 18.8-fold to >85.4-fold resistance to purified Cry1F protein and those collected from unexpectedly damaged Bt maize plants at several locations in Florida and North Carolina had >85.4-fold resistance. In addition, reduced efficacy and control failure of Cry1F maize against natural populations of S. frugiperda were documented in field trials using Cry1F-based and pyramided Bt maize products in south Florida. The Cry1F-resistant S. frugiperda also showed a low level of cross-resistance to Cry1A.105 and related maize products, but not to Cry2Ab2 or Vip3A. The occurrence of Cry1F resistance in the U.S. mainland populations of S. frugiperda likely represents migration of insects from Puerto Rico, indicating the great challenges faced in achieving effective resistance management for long-distance migratory pests like S. frugiperda.

In insects, these proteins play roles in metabolism, development, eye pigmentation, and xenobiotic clearance. While ABC transporters have been extensively studied in vertebrates, less is known concerning this superfamily in insects, particularly hemipteran pests. We used RNA-Seq transcriptome sequencing to identify 65 putative ABC transporter sequences (including 36 full-length sequences) from the eight ABC subfamilies in the western tarnished plant bug (Lygus hesperus), a polyphagous agricultural pest. Phylogenetic analyses revealed clear orthologous relationships with ABC transporters linked to insecticide/xenobiotic clearance and indicated lineage specific expansion of the L. hesperus ABCG and ABCH subfamilies. The transcriptional profile of 13 LhABCs representative of the ABCA, ABCB, ABCC, ABCG, and ABCH subfamilies was examined across L. hesperus development and within sex-specific adult tissues. All of the transcripts were amplified from both reproductively immature and mature adults and all but LhABCA8 were expressed to some degree in eggs. Expression of LhABCA8 was spatially localized to the testis and temporally timed with male reproductive development, suggesting a potential role in sexual maturation and/or spermatozoa protection. Elevated expression of LhABCC5 in Malpighian tubules suggests a possible role in xenobiotic clearance. Our results provide the first transcriptome-wide analysis of ABC transporters in an agriculturally important hemipteran pest and, because ABC transporters are known to be important mediators of insecticidal resistance, will provide the basis for future biochemical and toxicological studies on the role of this protein family in insecticide resistance in Lygus species.

Increased canopy openness and increased detritus (debris) deposition are two of the most likely factors, but due to their simultaneous occurrence during a hurricane, their relative effects cannot be separated without a manipulative experiment. Hence, in the Luquillo Experimental Forest (LEF) of Puerto Rico, the Luquillo Long-Term Ecological Research Program (LTER) has undertaken experimental manipulations in replicated 30 x 30 m plots to simulate the major effects of hurricane disturbance-increased canopy openness and debris addition to the forest floor. Using a factorial experiment enabled investigation of the separate and combined effects of canopy opening and debris on this wet tropical forest; the experimental outcomes may help direct forest management decisions in similar disturbance-prone environments. In this first article of the special issue, we (1) provide details of the design and methodology for this manipulative experiment (the Canopy Trimming Experiment, CTE), (2) report some principal abiotic responses to treatments, and (3) introduce the subject areas of the 12 additional CTE manuscripts in this special issue. The physical conditions created by canopy and understory treatment and the amounts of debris added to CTE plots were similar to the LEF's conditions following Hurricane Hugo (a category 4 storm) in 1989: although more wood and a 37% (1.5 cm) deeper litter layer was present in the CTE. Our selective cutting and removal of the forest canopy above 3 m, which included trimming 234 palm trees and 342 non-palm trees, greatly altered the understory micro-environment by increasing light levels and decreasing litter moisture for 18 months; throughfall and soil moisture were elevated in trim plots for 3 months. In plots where the canopy was trimmed and the debris (6 kg m(-2)) was added to the forest floor, the canopy debris persisted on the forest floor for at least 4 years; debris decomposed more quickly in plots with intact canopies. The diverse collection of papers in this special issue provide mechanistic understandings of response patterns of tropical forest biota (microbes, plants, animals) and processes (decomposition, herbivory, nutrient cycling, primary production) to canopy and understory disturbance that resembles a major ( >= category 3) hurricane. Although measurements for this experiment are ongoing to further identify the mechanisms of long-term forest change resulting from hurricanes, we include findings up to the first seven years post-treatment at this time.

Tropical trees often have low nutrient to carbon ratios. Disturbances such as hurricanes and logging transfer a large mass of green leaves with high nutrient concentrations to the forest floor, but the associated opening of the canopy dries the litter, inhibiting basidiomycete fungi that play critical roles in lignin degradation and nutrient conservation. We conducted a replicated block factorial experiment designed to disentangle the individual and interactive effects of canopy opening and green debris deposition on phosphorus (P) content, mass loss and fungal connectivity in decomposing leaf cohorts in subtropical wet forest in the Luquillo Mountains of Puerto Rico. Though green leaves had higher P concentrations they did not decompose significantly faster than senesced leaves. Mass loss differed among treatments after 14, 40.5 and 53 weeks decomposition. Mass loss at 7 weeks was predicted by P concentration at 7 weeks; mass loss in senesced leaves at 14 weeks was predicted by abundance of fungal connections between the senesced litter cohort and forest floor at 7 weeks. Fungal connectivity and P accumulation at 7 weeks and mass loss of senesced leaves beginning at 14 weeks were significantly different from and lower in plots with trimmed canopy and no debris than in the untrimmed plots with debris. Litter moisture was previously found to be significantly lower under open than closed canopy, and we found that moisture was a significant predictor of fungal connectivity in both senesced and green leaves. Deposition of green leaves ameliorated the inhibitory effect of canopy opening on fungal connectivity between litter cohorts by retaining moisture; consequently fungal connectivity and mass loss in senescent leaves did not differ between the Trim + Debris and the control treatments. Phosphorus content of senesced leaves increased significantly by 7 weeks in both trimmed and untrimmed plots with added green debris and in the control plots. Based on mass balance calculations, both the underlying forest floor and overlying green leaves likely contributed P to the decomposing senesced leaf cohort. Fungal translocation of P through hyphal connections between litter cohorts explains some of the changes in P content. Though fungi were important in conserving P, most of the P that was likely leached from green leaves was not retained in the litter layer. Published by Elsevier B.V. C1 [Lodge, D.

TI Effects of a simulated hurricane disturbance on forest floor microbial communities SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Soil and leaf litter microbial communities; Canopy opening; Debris addition; Green leaves; Senesced leaves; Spatiotemporal variations ID PUERTO-RICO; TROPICAL FORESTS; CLIMATE-CHANGE; WET FOREST; SOIL; DIVERSITY; BIOMASS; DECOMPOSITION; STABILITY; RESPONSES AB Forest floor microbial communities play a critical role in the processes of decomposition and nutrient cycling. The impact of cultivation, contamination, fire, and land management on soil microbial communities have been studied but there are few studies of microbial responses to the effects of tropical storms. The Canopy Trimming Experiment was executed in the Luquillo Experimental Forest of Puerto Rico to decouple two prominent effects of a hurricane-canopy opening and debris deposition on the forest floor-on forest biota and processes. We studied the independent and interactive hurricane effects of canopy openness and debris deposition on the relative abundance and diversity of microorganisms in soil and leaf litter using ester link fatty acids methyl esters (EL-FAME) analysis, and terminal restriction fragment length polymorphism (TRFLP) profile. Non-metric multi-dimensional scaling analysis of soil FAME showed soil microbial community composition was significantly different between pre- and post-hurricane periods including in the unmanipulated plots and among blocks, but there was no significant separation among treatments. This shows that there are strong spatiotemporal dynamics in the structure of soil microbial communities which masked hurricane effects (canopy opening and deposition of green debris). The degree of difference among treatments decreased with time in soil which suggests that our study may have started too late after the manipulations and therefore missed the effects of canopy opening and debris addition. This reflects the resilience of the soil microbial communities. The richness of soil bacterial TRF's however, showed a significant positive response to added debris. Neither fungal nor bacterial NMDS clusters for leaf microbial communities showed significant grouping by treatment, time or litter cohorts. Significant differences were observed through time for fungal diversity in green leaves and for both bacterial and fungal diversity in senesced leaves. Senesced leaves microbial succession apparently stopped when both the canopy and debris were removed, and there was a suggestive trimming by time interaction which reflects the susceptibility of the leaf litter microbial community. Our findings contribute to the understanding of how microbial community structures can be affected by hurricane disturbances and forestry management practices that remove canopy and debris from the forest floor, and shows the need to analyze the microbial community immediately after the disturbance. Short-term changes in microbial communities due to forest disturbances can have significant implications for litter decomposition, soil organic matter accumulation, nutrient cycling, and food web dynamics in tropical forests. All of these factors should be taken into consideration when selecting the appropriate forest management practice. (C) 2014 Elsevier B.V. All rights reserved.

TI A canopy trimming experiment in Puerto Rico: The response of litter decomposition and nutrient release to canopy opening and debris deposition in a subtropical wet forest SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Litter decomposition; Luquillo Experimental Forest; Manipulative experiment; Nutrient concentration; Nutrient release; Subtropical forest ID HARDWOOD LEAF-LITTER; TROPICAL RAIN-FOREST; SUB-ALPINE FORESTS; ORGANIC-MATTER; NITROGEN DYNAMICS; INVERTEBRATE COMMUNITIES; SPECIES COMPOSITION; NORTHERN HARDWOODS; HURRICANE DAMAGE; FOLIAR LITTER AB In this study, we used a replicated factorial design to separate the individual and interacting effects of two main components of a severe hurricane - canopy opening and green debris deposition on leaf litter decay in the tabonuco forest in the Luquillo Mountains of Puerto Rico. We quantify changes in percent mass remaining (PMR), the concentration and absolute amounts of various chemical elements using fresh (green) and senesced leaf litter contained in litterbags of two different mesh sizes. Mass loss was significantly slowed by canopy trimming. There was no significant effect of debris treatment on the PMR of the litter. Canopy trimming increased the percent of initial N, Al, Ca, Fe, and Mg remaining and decreased the percent of initial Mn remaining compared with not trimmed plots. Debris addition increased the percent of initial N and P remaining and decreased the percent of initial Al, and Fe remaining in the decomposing litter compared to no debris added plots. Of the elements studied, only Al and Fe accumulated above 100% of initial. Accumulation of Al and Fe in the canopy trimmed and no debris plots is most likely dominated by the adsorption of these ions onto the surfaces of the decaying litter. Overall, P showed a rapid initial loss during the first 0.2 yr followed by steady loss. Nitrogen was lost steadily from leaf litter. The PMR of fresh and senesced litter was significantly affected by mesh size, with a higher mass remaining in small mesh bags. Fresh litter decayed faster than senesced litter; following patterns of initial N and P concentrations (higher in the former litter type). We found a significantly negative correlation between the Margalef index of diversity for the litter arthropods contained in the litterbags and the PMR, suggesting functional complexity is an important determinant of decay in this forest. Our results imply hurricanes can differentially impact litter decomposition and associated nutrient release via canopy opening and litter inputs. Published by Elsevier B.V.

Severe storm events significantly alter patterns in litterfall mass and nutrient dynamics through a combination of canopy disturbance and litter deposition. In this study, we used a large-scale long-term manipulation experiment to explore the separate and combined effects of canopy trimming and litter deposition on litterfall rates and litter nutrient concentrations and content. The deposition of fine litter associated with the treatments was equivalent to more than two times the annual fine litterfall mass and nutrient content in control plots. Results showed that canopy trimming was the primary driver of changes in litterfall and associated nutrient cycling. Canopy trimming reduced litterfall mass by 14 Mg ha(-1) over the 2.5 year post-trim period. Nutrient concentrations increased in some litter fractions following trimming, likely due to a combination of changes in the species and fractional composition of litterfall, and increased nutrient uptake from reduced competition for nutrients. Declines in litterfall mass, however, led to large reductions in litterfall nutrient content with a loss of 143 +/- 22 kg N ha(-1) and 7 +/- 0.2 kg P ha(-1) over the 2.5 year post-trim period. There were no significant effects of litter deposition on litterfall rates or nutrient content, contrary to results from some fertilizer experiments. Our results suggest that large pulsed inputs of nutrients associated with tropical storms are unlikely to increase litterfall production, and that canopy disturbance has large and lasting effects on carbon and nutrient cycling.

TI Responses to canopy loss and debris deposition in a tropical forest ecosystem: Synthesis from an experimental manipulation simulating effects of hurricane disturbance SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE Canopy Trimming Experiment; Detritus; Long-term Ecological Research (LTER); Resistance-resilience; Tropical forest succession; Understory light ID LUQUILLO EXPERIMENTAL FOREST; SUBTROPICAL WET FOREST; PUERTO-RICO; RAIN-FOREST; LIGHT AVAILABILITY; CATASTROPHIC WIND; LARGE-SCALE; HUGO; DAMAGE; RECOVERY AB Hurricanes, cyclones, or typhoons are intense and broad-scale disturbances that affect many island and coastal ecosystems throughout the world. We summarize the findings of the articles that compose this special issue of Forest Ecology and Management, which focuses on a manipulative experiment (the Canopy Trimming Experiment, CTE) that simulates two key aspects of hurricane effects in a wet tropical forest. Although previous studies of tropical and subtropical forests have documented changes resulting from hurricanes, it is not clear which of the two simultaneously occurring direct effects of hurricanes-canopy openness or debris deposition-most influence responses. In the Luquillo Experimental Forest (LEF) of Puerto Rico, a multi-disciplinary team of scientists used replicated factorial manipulations to determine the independent and interactive effects of canopy openness and debris deposition on structural and functional characteristics of the forest. The majority of responses were primarily driven by canopy openness rather than by debris deposition. Canopy openness resulted in significant increases in densities of and compositional changes in woody plants, ferns, and some litter arthropods, and significant decreases in coqui frog abundances, leaf decomposition, and litterfall. Debris deposition significantly increased tree basal area and microbial diversity on leaf litter, but these increases were relatively small and ephemeral. Several interactive effects of canopy openness and debris addition emerged, including those involving understory herbivory, canopy arthropod structure, terrestrial gastropod abundances and composition, and soil solution chemistry. Arguably, hurricanes are the most important natural disturbance that affect the LEF, and most characteristics that were measured in the CTE showed evidence of resistance or resilience. By identifying the causal factors affecting secondary successional trajectories of diverse taxa ranging from microbes to vertebrates, biogeochemical attributes, microclimatic characteristics, and measures of ecosystem processes following hurricane disturbance, we better understand tropical forest dynamics resulting from past hurricanes and are better able to predict mechanisms of change related to future hurricanes.

To understand the immunomodulating effects of butyrate on avian macrophage, we treated a naturally transformed line of chicken macrophage cells named HTC with Na-butyrate in the absence or presence of Salmonella typhimurium lipopolysaccharide (LPS) or phorbol-12-myristate-13-acetate (PMA), a metabolic activator, evaluating its various functional parameters. The results demonstrate that, butyrate by itself had no significant effect on variables such as nitric oxide (NO) production and the expression of genes associated with various inflammatory cytokines but it inhibited NO production, and reduced the expression of cytokines such as IL-1 beta, IL-6, IFN-gamma, and IL-10 in LPS-stimulated cells. Butyrate decreased the expression of TGF-beta 3 in the presence or absence of LPS, while it had no effect on IL-4, T beta 4, and MMP2 gene expression. In addition, butyrate augmented PMA induced oxidative burst indicated by DCF-DA oxidation and restored LPS induced attenuation of tartrate resistant acid phosphatase (TRAP) activity. Although butyrate had no significant effect on phagocytosis or matrix metalloproteinase (MMP) activities of resting macrophages, it significantly suppressed the effects induced by their respective stimulants such as LPS induced phagocytosis and PMA induced MMP expression. These results suggest that butyrate has immunomodulatory property in the presence of agents that incite the cells thus, has potential to control inflammation and restore immune homeostasis.

CA Tioman Island Sarcocystosis Invest TI Acute Muscular Sarcocystosis: An International Investigation Among Ill Travelers Returning From Tioman Island, Malaysia, 2011-2012 SO CLINICAL INFECTIOUS DISEASES LA English DT Article DE infectious disease outbreak; sarcocystosis; parasitic disease; Malaysia; travel ID SKELETAL-MUSCLE; PENINSULAR MALAYSIA; MACACA-FASCICULARIS; PULAU TIOMAN; INFECTION; NESBITTI; OUTBREAK; SPP.; SNAKES; MONKEY AB Background. Through 2 international traveler-focused surveillance networks (GeoSentinel and TropNet), we identified and investigated a large outbreak of acute muscular sarcocystosis (AMS), a rarely reported zoonosis caused by a protozoan parasite of the genus Sarcocystis, associated with travel to Tioman Island, Malaysia, during 2011-2012. Methods. Clinicians reporting patients with suspected AMS to GeoSentinel submitted demographic, clinical, itinerary, and exposure data. We defined a probable case as travel to Tioman Island after 1 March 2011, eosinophilia (>5%), clinical or laboratory-supported myositis, and negative trichinellosis serology. Case confirmation required histologic observation of sarcocysts or isolation of Sarcocystis species DNA from muscle biopsy. Results. Sixty-eight patients met the case definition (62 probable and 6 confirmed). All but 2 resided in Europe; all were tourists and traveled mostly during the summer months. The most frequent symptoms reported were myalgia (100%), fatigue (91%), fever (82%), headache (59%), and arthralgia (29%); onset clustered during 2 distinct periods: "early" during the second and "late" during the sixth week after departure from the island. Blood eosinophilia and elevated serum creatinine phosphokinase (CPK) levels were observed beginning during the fifth week after departure. Sarcocystis nesbitti DNA was recovered from 1 muscle biopsy. Conclusions. Clinicians evaluating travelers returning ill from Malaysia with myalgia, with or without fever, should consider AMS, noting the apparent biphasic aspect of the disease, the later onset of elevated CPK and eosinophilia, and the possibility for relapses. The exact source of infection among travelers to Tioman Island remains unclear but needs to be determined to prevent future illnesses.

TI Temporal and spatial variability of frost-free seasons in the Great Lakes region of the United States SO INTERNATIONAL JOURNAL OF CLIMATOLOGY LA English DT Article DE frost dates; frost-free season; the Great Lakes region; Pacific Decadal Oscillation ID ASSIMILATION SYSTEM NLDAS; MIDLATITUDE SST ANOMALIES; ATMOSPHERIC RESPONSE; CLIMATE-CHANGE; NORTH-AMERICA; REANALYSIS; SNOW; OSCILLATION; TRENDS; TEMPERATURE AB The frequency and timing of frost events and the length of the growing season are critical limiting factors in many human and natural ecosystems. This study investigates the temporal and spatial variability of the date of last spring frost (LSF), the date of first fall frost (FFF), and the length of the frost-free season (FFS) in the Great Lakes region of the United States using two gridded reanalysis datasets for the period of 1980-2010. Across most of the Great Lakes region, there has been a negative trend for the LSF and a positive trend for the FFF, leading to a lengthening of FFS. The three variables vary spatially across the region and exhibit large interannual variability. Empirical orthogonal function (EOF) analyses indicate that the first mode for the three variables, which accounts for about 30% of the total variance, is in phase across most of the Great Lakes region and that it appears to be related to Pacific North American (PNA) pattern in the case of LSF and to Pacific Decadal Oscillation (PDO) in the case of FFF and FFS. The main reason for these connections is that the 200-hPa geopotential height anomaly over North America induced by a Rossby wave train influences the strength of the trough over North America, which in turn affects surface temperatures over the Great Lakes region. The second mode, explaining about 10% of the total variance, mainly shows the out-of-phase variability between the Great Lakes and the surrounding land and it appears to be related to the circumglobal teleconnection (CGT) in the case of LSF and again to PDO in the case of FFF and FFS.

TI Effect of Omega-3 Fatty Acid Ethyl Esters on the Oxylipin Composition of Lipoproteins in Hypertriglyceridemic, Statin-Treated Subjects SO PLOS ONE LA English DT Article ID SOLUBLE EPOXIDE HYDROLASE; ACTIVATES PPAR-ALPHA; TREATMENT PANEL-III; FATTY-ACIDS; EPOXYEICOSATRIENOIC ACIDS; ATHEROSCLEROSIS; INFLAMMATION; CHOLESTEROL; CHANNELS; PLASMA AB Background: Oxylipins mediate inflammation, vascular tension, and more. Their presence in lipoproteins could explain why lipoproteins mediate nearly identical activities. Methods: To determine how oxylipins are distributed in the lipoproteins of hypertriglyceridemic subjects, and whether omega-3 fatty acids alter them in a manner consistent with improved cardiovascular health, we recruited 15 dyslipidemic subjects whose levels of low density lipoprotein cholesterol (LDL-C) were at goal but who remained hypertriglyceridemic (200-499 mg/dL). They were treated them with the indicated dose of 4 g/d omega-3 acid ethyl esters (P-OM3) for 8 weeks. Measured oxylipins included mid-chain alcohols (HETEs, HEPEs and HDoHEs), ketones (KETEs), epoxides (as EpETrEs, EpETEs, and EpDPEs). Results: At baseline, arachidonate-oxylipins (HETEs, KETEs, and EpETrEs) were most abundant in plasma with the greatest fraction of total abundance (mean vertical bar 95% CI vertical bar) being carried in high density lipoproteins (HDL); 42% vertical bar 31, 57 vertical bar followed by very low density lipoproteins (VLDL); 27% vertical bar 20, 36 vertical bar; and LDL 21% vertical bar 16, 28 vertical bar. EPA- and DHA-derived oxylipins constituted less than 11% of total. HDL carried alcohols and epoxides but VLDL was also rich in ketones. Treatment decreased AA-derived oxylipins across lipoprotein classes (-23% vertical bar-33, -12 vertical bar, p = 0.0003), and expanded EPA-(322% vertical bar 241, 422 vertical bar, p<0.0001) and DHA-derived oxylipins (123% vertical bar 80, 176 vertical bar, p<0.0001). Conclusions: Each lipoprotein class carries a unique oxylipin complement. P-OM3 treatment alters the oxylipin content of all classes, reducing pro-inflammatory and increasing anti-inflammatory species, consistent with the improved inflammatory and vascular status associated with the treatment.

The disease was first reported in the western United States (USA) on several Juglans species, but has been found more recently in the eastern USA in the native range of the highly susceptible Juglans nigra. We performed a comprehensive population genetic study of 209 G. morbida isolates collected from Juglans and Pterocarya from 17 geographic regions distributed across 12 U.S. states. The study was based on sequence typing of 27 single nucleotide polymorphisms from three genomic regions and genotyping with ten microsatellite primer pairs. Using multilocus sequence-typing data, 197 G. morbida isolates were placed into one of 57 haplotypes. In some instances, multiple haplotypes were recovered from isolates collected on the same tree. Twenty-four of the haplotypes (42%) were recovered from more than one isolate; the two most frequently occurring haplotypes (H02 and H03) represented 36% of all isolates. These two haplotypes were abundant in California, but were not recovered from Arizona or New Mexico. G. morbida population structure was best explained by four genetically distinct groups that clustered into three geographic regions. Most of the haplotypes isolated from the native range of J. major (Arizona and New Mexico) were found in those states only or present in distinct genetic clusters. There was no evidence of sexual reproduction or genetic recombination in any population. The scattered distribution of the genetic clusters indicated that G. morbida was likely disseminated to different regions at several times and from several sources. The large number of haplotypes observed and the genetic complexity of G. morbida indicate that it evolved in association with at least one Juglans spp. and the walnut twig beetle long before the first reports of the disease.

TI Aggregate Tensile Strength and Friability Characteristics of Furrow and Sprinkler Irrigated Fields in Southern Idaho SO COMMUNICATIONS IN SOIL SCIENCE AND PLANT ANALYSIS LA English DT Article DE Soil structure; tensile strength; soil tilth ID SOIL FRIABILITY; MANAGEMENT AB Agricultural crops grown in southern Idaho are furrow or sprinkler irrigated. Therefore, the soil experiences several wetting and drying cycles each growing season that can contribute to changes in aggregate tensile strength and friability. The objective of the research was to evaluate the influence of irrigation on soil structural properties. Four furrow-irrigated fields were sampled at the top and bottom of the field, in the furrow and on the bed location of the furrow. Five sprinkler-irrigated fields were sampled at depths of 0-5 and 5-15 cm and at the top and bottom of the field. Results from this study indicate that differences in tensile strength in furrow-irrigated fields were only evident soon after irrigation; otherwise, there were few differences in tensile strength and friability. In sprinkler-irrigated fields tensile strength increased with depth in three of the five fields measured. Friability was less affected by depth.

Breeding Cycle Using Genomic Selection Approaches SO PLOS ONE LA English DT Article ID LOWLAND SWITCHGRASS; DAIRY-CATTLE; PREDICTION; REGRESSION; ACCURACY; PLANT; POPULATION; TRAITS; MODELS; MAIZE AB Switchgrass (Panicum virgatum L.) is a perennial grass undergoing development as a biofuel feedstock. One of the most important factors hindering breeding efforts in this species is the need for accurate measurement of biomass yield on a per-hectare basis. Genomic selection on simple-to-measure traits that approximate biomass yield has the potential to significantly speed up the breeding cycle. Recent advances in switchgrass genomic and phenotypic resources are now making it possible to evaluate the potential of genomic selection of such traits. We leveraged these resources to study the ability of three widely-used genomic selection models to predict phenotypic values of morphological and biomass quality traits in an association panel consisting of predominantly northern adapted upland germplasm. High prediction accuracies were obtained for most of the traits, with standability having the highest ten-fold cross validation prediction accuracy (0.52). Moreover, the morphological traits generally had higher prediction accuracies than the biomass quality traits. Nevertheless, our results suggest that the quality of current genomic and phenotypic resources available for switchgrass is sufficiently high for genomic selection to significantly impact breeding efforts for biomass yield.

TI Efficacy of Type 2 PRRSV vaccine against Chinese and Vietnamese HP-PRRSV challenge in pigs SO VACCINE LA English DT Article DE HP-PRRSV; Swine; PRRSV vaccine ID RESPIRATORY-SYNDROME-VIRUS; PROTECTIVE IMMUNITY; STRAIN; EMERGENCE; SWINE; PATHOGENICITY; ISOLATE AB Porcine reproductive and respiratory syndrome virus (PRRSV) causes significant reproductive losses in the sow herd and respiratory disease in growing pigs. The virus belongs to the family Arteriviridae and there are two major genotypes. Type 1 is represented by Lelystad virus, the European prototype virus, and Type 2 is represented by the North American prototype virus, VR-2332. Depending on husbandry, immune status of the herd, and virulence of the isolate, the severity of disease and magnitude of economic loss can be variable. Vaccine use is not always successful indicating a lack of cross-protection between vaccine strains and circulating wild-type viruses. To date, there is no clear method to demonstrate if a vaccine confers protection against a specific isolate except for empirical animal studies. In 2006, a new lineage of Type 2 PRRSV emerged in Chinese swine herds that were suffering dramatic losses resulting in those viruses being described as "Highly Pathogenic PRRSV" (HP-PRRSV). Experimental reproduction of severe disease with HP-PRRSV isolates and virus derived from HP-PRRSV clones demonstrated the causal role of this virus. Recently, partial heterologous protection has been reported for Type 1 and Type 2 attenuated PRRSV vaccines against challenge by different Chinese HP-PRRSV isolates providing some hope for reducing economic loss. This paper reports the efficacy of a commercially available Type 2 attenuated vaccine in young pigs against heterologous challenge with a Chinese and Vietnamese HP-PRRSV isolate. When compared to unvaccinated pigs, vaccination decreased the length of viremia and viral titer, diminished the time of high fever and reduced macroscopic lung scores following homologous and heterologous PRRSV challenge. These results demonstrate the potential use of vaccine as an aid in the control of HP-PRRSV outbreaks. (C) 2014 Published by Elsevier Ltd.

TI Influence of Soil Biochar Aging on Sorption of the Herbicides MCPA, Nicosulfuron, Terbuthylazine, Indaziflam, and Fluoroethyldiaminotriazine SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE MCPA; terbuthylazine; nicosulfuron; indaziflam; biochar; aging ID DISSOLVED ORGANIC-MATTER; BLACK CARBON; IRREVERSIBLE SORPTION; CLAY-MINERALS; ADSORPTION; AMENDMENTS; DESORPTION; SEDIMENTS; SURFACES; BEHAVIOR AB Sorption of four herbicides and a metabolite of indaziflam on a fresh macadamia nut biochar and biochars aged one or two years in soil was characterized. On fresh biochar, the sorption was terbuthylazine (K-d = 595) > indaziflam (K-d = 162) > MCPA (K-d = 7.5) > fluoroethyldiaminotriazine (K-d = 0.26) and nicosulfuron (K-d = 0). Biochar surface area increased with aging attributed to the loss of a surface film. This was also manifested in a decline in water extractable organic carbon with aging. Correspondingly, an increase in the aromaticity was observed. The higher surface area and porosity in aged biochar increased sorption of indaziflam (KdBC-2yr = 237) and fluoroethyldiaminotriazine (KdBC-1yr = 1.2 and KdBC-2yr = 3.0), but interestingly decreased sorption of terbuthylazine (KdBC-1yr = 312 and KdBC-2yr = 221) and MCPA (KdBC-1yr = 2 and KdBC-2yr = 2). These results will facilitate development of biochars for specific remediation purposes. C1 [Trigo, Carmen] Univ Minnesota, Dept Soil Water & Climate, St Paul, MN 55108 USA.

We present a landscape-level, spatially explicit model of trap networks, focused on detection, that incorporates variable attractiveness of traps and a movement model for insect dispersion. We describe the model and validate its behavior using field trap data on networks targeting two species, Ceratitis capitata and Anoplophora glabripennis. Our model will assist efforts to optimize trap networks by 1) introducing an accessible and realistic mathematical characterization of the operation of a single trap that lends itself easily to parametrization via field experiments and 2) allowing direct quantification and comparison of sensitivity between trap networks. Results from the two case studies indicate that the relationship between number of traps and their spatial distribution and capture probability under the model is qualitatively dependent on the attractiveness of the traps, a result with important practical consequences.

Proteome rebalancing of seed proteins has been shown to promote the accumulation of foreign proteins. In this study, we have utilized RNAi technology to suppress the expression of the beta-conglycinin, the abundant 7S seed storage proteins of soybean. Western blot and 2D-gel analysis revealed that beta-conglycinin knockdown line (SAM) failed to accumulate the alpha', alpha, and beta-subunits of beta-conglycinin. The proteome rebalanced SAM retained the overall protein and oil content similar to that of wild-type soybean. We also generated transgenic soybean lines expressing methionine-rich 11 kDa delta-zein under the control of either the glycinin or beta-conglycinin promoter. The introgression of the 11 kDa delta-zein into beta-conglycinin knockdown line did not enhance the accumulation of the 11 kDa delta-zein. However, when the same plants were grown in sulfur-rich medium, we observed 3-to 16-fold increased accumulation of the 11 kDa delta-zein. Transmission electron microscopy observation revealed that seeds grown in sulfur-rich medium contained numerous endoplasmic reticulum derived protein bodies. Our findings suggest that sulfur availability, not proteome rebalancing, is needed for high-level accumulation of heterologous methionine-rich proteins in soybean seeds.

Developing heat tolerant cultivars has become a principal breeding goal in the Southern and Central Great Plain areas of the USA. Traits associated with high temperature tolerance can be used to develop heat tolerant cultivars in wheat. The present study was conducted to identify chromosomal regions associated with thylakoid membrane damage (TMD), plasmamembrane damage (PMD), and SPAD chlorophyll content (SCC), which are indicative of high temperature tolerance. Results: In this study we have reported one of the first linkage maps in wheat using genotype by sequencing SNP (GBS-SNP) markers to extreme response to post anthesis heat stress conditions. The linkage map was comprised of 972 molecular markers (538 Bin, 258 AFLPs, 175 SSRs, and an EST). The genotypes of the RIL population showed strong variation for TMD, SCC and PMD in both generations (F-10 and F-9). Composite interval mapping identified five QTL regions significantly associated with response to heat stress. Associations were identified for PMD on chromosomes 7A, 2B and 1D, SCC on 6A, 7A, 1B and 1D and TMD on 6A, 7A and 1D. The variability (R-2) explained by these QTL ranged from 11.9 to 30.6% for TMD, 11.4 to 30.8% for SCC, and 10.5 to 33.5% for PMD. Molecular markers Xbarc113 and AFLP AGCTCG-347 on chromosome 6A, Xbarc121 and Xbarc49 on 7A, gwm18 and Bin1130 on 1B, Bin178 and Bin81 on 2B and Bin747 and Bin1546 on 1D were associated with these QTL. Conclusion: The identified QTL can be used for marker assisted selection in breeding wheat for improved heat tolerance in Ventnor or Karl 92 genetic background.

TI Transcriptome of the Invasive Brown Marmorated Stink Bug, Halyomorpha halys (Stal) (Heteroptera: Pentatomidae) SO PLOS ONE LA English DT Article ID HEMIPTERA-PENTATOMIDAE; AGGREGATION PHEROMONE; RHODNIUS-PROLIXUS; DESERT LOCUST; PROTEIN; RECOGNITION; SCAVENGER; FUNGI; BLAST; SUITE AB Halyomorpha halys (Stal) (Heteroptera: Pentatomidae), the brown marmorated stink bug, is an invasive agricultural and nuisance pest rapidly expanding its incidence in North America. This voracious pest poses a significant threat to rural and urban agriculture, especially to specialty crops such as apples, grapes and ornamentals, as well as staple crops including soybean and corn. The object of this study was to generate transcript sequence resources for H. halys. RNA-seq libraries derived from distinct developmental stages and sexes were sequenced and assembled into 248,569 putatively unique transcripts (PUTs). PUTs were segmented into three disjoint tiers of varying reliability, with 4,794 classified as gold tier (highest quality), 16,878 as silver, and 14,357 as bronze. The gold-tier PUTs associated with 2,580 distinct non-redundant protein sequences from the NCBI NR database-1,785 of these (69%) mapped to annotated UniProtKB database proteins, from which 1,273 unique Pfam families and 459 unique Molecular Function GO terms were encountered. Of the silver tier's 6,527 PUTs associated with unique proteins, 4,193 mapped to UniProtKB (64%), from which 1,941 and 640 unique Pfam and Molecular Function GO terms were extracted. H. halys PUTs related to important life processes like immunity, endocrinology, reproduction, development, behavior, neurotransmission, neurotoxicity, olfaction, and small RNA pathways were validated through quantitative Real-Time PCR (qRT-PCR) for differential expression during distinct life stages (eggs, 2nd instar nymphs, 4th instar nymphs, female adults, male adults). PUTs similar to hypothetical proteins identified in symbiont microbes, including Pantoea and Nosema species, were more abundantly expressed in adults versus nymphs. These comprehensive H. halys transcriptomic resources can be utilized to aid development of novel control methodologies to disrupt life processes; to conduct reverse genetic screens to determine host gene function; and to design environmentally unobtrusive means to control host populations or target specific H. halys life stages, such as molecular biopesticides.

As a potential carcinogen, RDX can cause a broad range of harmful effects to humans and animals. The ovine rumen is capable of rapid degradation of nitroaromatic compounds, including RDX. While ruminal RDX-degrading bacteria have been identified, the genes and pathways responsible for RDX degradation in the rumen have yet to be characterized. In this study, we characterized the metabolic potential of the ovine rumen using metagenomic approaches. Sequences homologous to at least five RDX-degrading genes cloned from environmental samples (diaA, xenA, xenB, xplA, and xplB) were present in the ovine rumen microbiome. Among them, diaA was the most abundant, likely reflective of the predominance of the genus Clostridium in the ovine rumen. At least ten genera known to harbor RDX-degrading microorganisms were detectable. Metagenomic sequences were also annotated using public databases, such as Pfam, COG, and KEGG. Five of the six Pfam protein families known to be responsible for RDX degradation in environmental samples were identified in the ovine rumen. However, increased substrate availability did not appear to enhance the proliferation of RDX-degrading bacteria and alter the microbial composition of the ovine rumen. This implies that the RDX-degrading capacity of the ovine rumen microbiome is likely regulated at the transcription level. Our results provide metagenomic insights into the RDX-degrading potential of the ovine rumen, and they will facilitate the development of novel and economic bioremediation strategies.

TI Learning to coexist with wildfire SO NATURE LA English DT Review ID WILDLAND-URBAN INTERFACE; FUEL-REDUCTION TREATMENTS; WESTERN UNITED-STATES; FIRE REGIMES; CLIMATE-CHANGE; BIODIVERSITY CONSERVATION; MEDITERRANEAN BASIN; RISK-MANAGEMENT; GLOBAL CHANGE; FORESTS AB The impacts of escalating wildfire in many regions - the lives and homes lost, the expense of suppression and the damage to ecosystem services - necessitate a more sustainable coexistence with wildfire. Climate change and continued development on fire-prone landscapes will only compound current problems. Emerging strategies for managing ecosystems and mitigating risks to human communities provide some hope, although greater recognition of their inherent variation and links is crucial. Without a more integrated framework, fire will never operate as a natural ecosystem process, and the impact on society will continue to grow. A more coordinated approach to risk management and land-use planning in these coupled systems is needed.

Better characterization of surface albedo for individual land cover types can reduce the uncertainty in estimating changes to Earth's radiation balance due to land cover change. This paper presents albedo look-up maps (LUMs) using a multiscale hierarchical approach based on moderate resolution imaging spectroradiometer (MODIS) bidirectional reflectance distribution function (BRDF)/albedo products and Landsat imagery. Ten years (2001 to 2011) of MODIS BRDF/albedo products were used to generate global albedo climatology. Albedo LUMs of land cover classes defined by the International Geosphere-Biosphere Programme (IGBP) at multiple spatial resolutions were generated. The albedo LUMs included monthly statistics of white sky (diffuse) and black sky (direct) albedo for each IGBP class for visible, near infrared, and shortwave broadband under both snow free and snow covered conditions. The albedo LUMs were assessed by using the annual MODIS IGBP land cover map and the projected land use scenarios from the Intergovernmental Panel on Climate Change land use harmonization project. The comparisons between the reconstructed albedo and the MODIS albedo data product show good agreement. The LUMs provide high temporal and spatial resolution global albedo statistics without gaps for investigating albedo variations under different land cover scenarios and could be used for land surface modeling.

However, the currently licensed pathogen reduction techniques are ineffective against non-enveloped viruses such as hepatitis A virus, and they introduce chemicals with concerns of side effects which prevent their widespread use. In this report, we demonstrate the inactivation of both enveloped and non-enveloped viruses in human plasma using a novel chemical-free method, a visible ultrashort pulsed laser. We found that laser treatment resulted in 2-log, 1-log, and 3-log reductions in human immunodeficiency virus, hepatitis A virus, and murine cytomegalovirus in human plasma, respectively. Laser-treated plasma showed >= 70% retention for most coagulation factors tested. Furthermore, laser treatment did not alter the structure of a model coagulation factor, fibrinogen. Ultrashort pulsed lasers are a promising new method for chemical-free, broad-spectrum pathogen reduction in human plasma.

To date, there is no established cure for this century-old and yet, newly emerging disease. As a potential control strategy for citrus HLB, 31 antibiotics were screened for effectiveness and phytotoxicity using the optimized graft-based screening system with 'Candidatus Liberibacter asiaticus' (Las)-infected citrus scions. Actidione and Oxytetracycline were the most phytotoxic to citrus with less than 10% of scions surviving and growing; therefore, this data was not used in additional analyses. Results of principal component (PCA) and hierarchical clustering analyses (HCA) demonstrated that 29 antibiotics were clustered into 3 groups: highly effective, partly effective, and not effective. In spite of different modes of actions, a number of antibiotics such as, Ampicillin, Carbenicillin, Penicillin, Cefalexin, Rifampicin and Sulfadimethoxine were all highly effective in eliminating or suppressing Candidatus Liberibacter asiaticus indicated by both the lowest Las infection rate and titers of the treated scions and inoculated rootstock. The non-effective group, including 11 antibiotics alone with three controls, such as Amikacin, Cinoxacin, Gentamicin, Kasugamycin, Lincomycin, Neomycin, Polymixin B and Tobramycin, did not eliminate or suppress Las in the tested concentrations, resulting in plants with increased titers of Las. The other 12 antibiotics partly eliminated or suppressed Las in the treated and graft-inoculated plants. The effective and non-phytotoxic antibiotics could be potential candidates for control of citrus HLB, either for the rescue of infected citrus germplasm or for restricted field application.

The abundance of alpha-and beta-globin transcripts in blood, however, impedes the ability to cost-effectively detect transcripts of low abundance. Although protocols exist for reduction of globin transcripts from human and mouse/rat blood, preliminary work demonstrated these are not useful for porcine blood Globin Reduction (GR). Our objectives were to develop a porcine specific GR protocol and to evaluate the GR effects on gene discovery and sequence read coverage in RNA-sequencing (RNA-seq) experiments. Results: A GR protocol for porcine blood samples was developed using RNase H with antisense oligonucleotides specifically targeting porcine hemoglobin alpha (HBA) and beta (HBB) mRNAs. Whole blood samples (n = 12) collected in Tempus tubes were used for evaluating the efficacy and effects of GR on RNA-seq. The HBA and HBB mRNA transcripts comprised an average of 46.1% of the mapped reads in pre-GR samples, but those reads reduced to an average of 8.9% in post-GR samples. Differential gene expression analysis showed that the expression level of 11,046 genes were increased, whereas 34 genes, excluding HBA and HBB, showed decreased expression after GR (FDR <0.05). An additional 815 genes were detected only in post-GR samples. Conclusions: Our porcine specific GR primers and protocol minimize the number of reads of globin transcripts in whole blood samples and provides increased coverage as well as accuracy and reproducibility of transcriptome analysis. Increased detection of low abundance mRNAs will ensure that studies relying on transcriptome analyses do not miss information that may be vital to the success of the study.

To better document the corn-related land use change, this study mapped the spatial distributions of four major annual crops (corn, soybean, winter wheat, and spring wheat) and three perennial crops (shortgrass, warm-season tallgrass, and cool-season tallgrass) in the Midwest. From 2006 to 2008, the 8-day, 500-m moderate resolution imaging spectroradiometer (MODIS) surface reflectance products were used to retrieve the normalized difference vegetation index (NDVI) composites. A support vector machine classifier was applied to identify these crops based on their unique growth cycles reflected from NDVI trajectories. The results showed a net increase of 15% of corn fields in 2007 accompanied by a net decrease of 16% in 2008. With the season-long integrated NDVI, this study also explored the geographic context and biomass proxy of native perennial grasses, an important feedstock of cellulosic biofuel. Mostly growing in North Dakota, South Dakota, Nebraska, and Kansas, their biomass quantities increased from west to east. This study indicates that frequent satellite observations may provide an efficient tool for monitoring biomass supplies and land use changes to assist national bioenergy decision-making.

In this study, the effects of the synergistic interaction between WSMV and TriMV on endogenous and virus-derived small interfering RNAs (vsiRNAs) were examined in susceptible ('Arapahoe') and temperature-sensitive resistant ('Mace') wheat cultivars at 18 degrees C and 27 degrees C. Single and double infections in wheat caused a shift in the profile of endogenous small RNAs from 24 nt being the most predominant in healthy plants to 21 nt in infected wheat. Massive amounts of 21 and 22 nt vsiRNAs accumulated in singly and doubly infected Arapahoe at both temperatures and in Mace at 27 degrees C but not 18 degrees C. The plus-and minus-sense vsiRNAs were distributed throughout the genomic RNAs in Arapahoe at both temperature regimens and in Mace at 27 degrees C, although some regions served as hot-spots, spawning an excessive number of vsiRNAs. The vsiRNA peaks were conserved among cultivars, suggesting that the Dicer-like enzymes in susceptible and resistant cultivars similarly accessed the genomic RNAs of WSMV or TriMV. Accumulation of large amounts of vsiRNAs in doubly infected plants suggests that the silencing suppressor proteins encoded by TriMV and WSMV do not prevent the formation of vsiRNAs; thus, the synergistic effect observed is independent from RNA-silencing mediated vsiRNA biogenesis. The high-resolution map of endogenous and vsiRNAs from WSMV-and/or TriMV-infected wheat cultivars may form a foundation for understanding the virus-host interactions, the effect of synergistic interactions on host defense, and virus resistance mechanisms in wheat.

Many HD-Zip genes are characterized in Arabidopsis (Arabidopsis thaliana), and members of the family are being investigated for abiotic stress responses in rice (Oryza sativa), maize (Zea mays), poplar (Populus trichocarpa) and cucumber (Cucmis sativus). Findings in these species suggest HD-Zip genes as high priority candidates for crop improvement. Results: In this study we have identified members of the HD-Zip gene family in soybean cv. 'Williams 82', and characterized their expression under dehydration and salt stress. Homology searches with BLASTP and Hidden Markov Model guided sequence alignments identified 101 HD-Zip genes in the soybean genome. Phylogeny reconstruction coupled with domain and gene structure analyses using soybean, Arabidopsis, rice, grape (Vitis vinifera), and Medicago truncatula homologues enabled placement of these sequences into four previously described subfamilies. Of the 101 HD-Zip genes identified in soybean, 88 exist as whole-genome duplication-derived gene pairs, indicating high retention of these genes following polyploidy in Glycine similar to 13 Mya. The HD-Zip genes exhibit ubiquitous expression patterns across 24 conditions that include 17 tissues of soybean. An RNA-Seq experiment performed to study differential gene expression at 0, 1, 6 and 12 hr soybean roots under dehydration and salt stress identified 20 differentially expressed (DE) genes. Several of these DE genes are orthologs of genes previously reported to play a role under abiotic stress, implying conservation of HD-Zip gene functions across species. Screening of HD-Zip promoters identified transcription factor binding sites that are overrepresented in the DE genes under both dehydration and salt stress, providing further support for the role of HD-Zip genes in abiotic stress responses. Conclusions: We provide a thorough description of soybean HD-Zip genes, and identify potential candidates with probable roles in dehydration and salt stress. Expression profiles generated for all soybean genes, under dehydration and salt stress, at four time points, will serve as an important resource for the soybean research community, and will aid in understanding plant responses to abiotic stress.

In this article we describe disturbance risk perceptions from interviews with residents in three Florida communities that face significant wildfire and hurricane risk. Although they live in areas characterized by emergency managers as having high wildfire risk and many participants have direct experience with wildfire, residents tended to share high hurricane and low wildfire risk perceptions. The different perceptions of risk seem linked to several factors: direct hurricane experience, different scales of impact, the local "hurricane culture," effectiveness of local ordinances and development patterns, perceived predictability of the event, and perceived ability to control the event. This study shows that residents may perceive and act to reduce risk for one disturbance in relation to their perceptions, concern, and actions for another.

Functions include coagulation and regulation of calcification. Different clinical conditions may alter vitamin K requirements by affecting vitamin K status and vitamin K-dependent proteins carboxylation that are reviewed here. Recent findings Vitamin K consumption greater than the current usual daily requirement to maintain health is indicated for prevention of vitamin K-deficient bleeding in infants and for rescue of over-anticoagulation in patients on vitamin K-dependent oral anticoagulants. Additional vitamin K intake may be required in malabsorptive conditions such as cystic fibrosis and following bariatric surgery. Carboxylation of vitamin K-dependent proteins occurs in multiple extrahepatic tissues and has been implicated in soft tissue calcification and insulin resistance, although the exact mechanisms have yet to be determined. Contribution of colonic flora to vitamin K requirements remains controversial. Summary With the increased incidence of vitamin K-deficient bleeding and weight-loss surgical procedures, healthcare professionals need to monitor vitamin K status in certain patient populations. Future research on the roles of vitamin K in extrahepatic tissues as they pertain to chronic disease will provide insight into the therapeutic potential of vitamin K and lead to the development of recommendations for specific clinical populations.

A total of 44 lentil (Lens culinaris Medik.) accessions, were screened for resistance to PEMV. Two accessions (PI 431663 and PI 432028) were identified with resistance to PEMV in field tests while several accessions were found resistant in greenhouse screenings. Thirty-six polymorphic simple sequence repeat (SSR) markers which produced 43 loci with 2 to 12 alleles per locus were used for genetic diversity analysis. The polymorphic information content (PIC) values for these markers ranged from 0.22-0.85 with a mean of 0.55 per marker. Using allelic data of 36 SSR primer pairs, dissimilarity ranging from 0.12 to 0.74 was calculated. Cluster analysis performed using the unweighted pair group method with arithmetic mean (UPGMA) determined that most of PEMV-resistant accessions were grouped in one cluster along with other accessions from Iran, Chile, Ethiopia, India, Pakistan, Turkey, Afghanistan and Lebanon. All the adapted cultivars originating from North and South America were grouped in another cluster along with some European accessions. The 44 accessions were classified into 4 subpopulations using Structure 2.2 software complimenting the results of UPGMA analysis and indicated the effect of geographical origin on the grouping of accessions. The results of this study can be used to select genetically diverse PEMV-resistant accessions for lentil improvement programs.

All the offspring of the females that received 20% or 30% I. asarifolia showed tremors 2-4 days after birth. The offspring of the females that received 20% I. asarifolia recovered 4-7 days after weaning. The offspring of the females that received 30% of the plant in the ration died while showing tremors before weaning or up to two days after weaning. It is concluded that the tremorgenic compound of I. asarifolia or its toxic metabolites are eliminated in milk, and that lactating mice may be used as a model for the determination of the toxic compound(s) in this plant.

Softwood forest residue represents a significant amount of woody biomass that can be sustainably used to produce biofuel. It also has very low contents of acetyl groups and 5-carbon polysaccharides, favorable for biofuel production through yeast fermentation. However, it is highly recalcitrant to enzymatic saccharification due to high bark and lignin content. Most existing pretreatment processes are unable to remove this recalcitrance. Sulfite pretreatment to overcome the recalcitrance of lignocelluloses (SPORL) has demonstrated unparalleled performance for bioconversion of softwoods. In this study, we evaluated SPORL process for bioconversion of un-detoxified Douglas-fir forest residue at a high solids loading to ethanol.

This research tries to understand the mode of action of the two piperazine-phosphonates derivatives on cotton fabric. The investigation proceeds by preparing Tetraethyl piperazine-1,4-diyldiphosphonate (TEPP) and Diethyl 4-methyl piperazin-1-ylphosphoramidate (DEPP), engrafting them on cotton fabric and studying their mechanism of thermal degradation on fabric. In studying the mechanism, we learned the chemical functional groups of the chemicals on the surface of the treated fabrics and of the evolved gases produced thermogravimetrically and pyrolytically by using different analytical techniques such as attenuated total reflection infrared (ATR-IR), thermogravimetric analysis-Fourier transform infrared (TGA-FTIR) spectroscopy and pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS).

In the transgenic event B52a6, HMW-GS 1Dy10 was produced at respective rates of 6.7 and 4.6 times higher than those of non-transgenic B52a6 siblings and control cultivars. In transgenic event Dy10-E, the observed amount of 1Dy10 was approximately 5.7 and 5.8 fold greater than those of non-transgenic Dy10-E derivatives and controls. Event Dx5 + Dy10-H over-produced HMW-GS 1Dx5 at rates of approximately five to six fold higher than I non-transgenic siblings and controls, respectively. All three transgenic events exhibited significantly greater average molecular mass of glutenin than those of both controls and the respective non-transgenic siblings. The transgenic Dy10-E event displayed the largest polymer molecular weight distribution. The percentage of protein found in polymeric form, however, did not increase in any of the three events. Technological properties, including mixograph time to peak, mixograph tolerance, bake mix time and loaf volume were strongly dependent upon the average M-w and glutenin quantity.

TI Virulence of Two Strains of Mycobacterium bovis in Cattle Following Aerosol Infection SO JOURNAL OF COMPARATIVE PATHOLOGY LA English DT Article DE bovine tuberculosis; immunity; Mycobacterium bovis; virulence ID WHITE-TAILED DEER; IMMUNE-RESPONSES; TUBERCULOSIS; ASSAY; ERADICATION; PROGRESSION; KANSASII; LESIONS; MODEL AB Over the past two decades, highly virulent strains of Mycobacterium tuberculosis have emerged and spread rapidly in man, suggesting a selective advantage based on virulence. A similar scenario has not been described for Mycobacterium bovis infection in cattle (i.e. bovine tuberculosis). An epidemiological investigation of a recent outbreak of bovine tuberculosis in a USA dairy indicated that the causative strain of M. bovis (strain 107428) was particularly virulent, with rapid spread within the herd. In the present study, the virulence of this strain (10-7428) was directly compared in the target host with a well-characterized strain (95-1315) of relevance to the USA bovine tuberculosis eradication programme. Aerosol inoculation of 104 colony forming units of M. bovis 95-1315 (n = 8) or 10-7428 (n = 8) resulted in a similar distribution and severity of gross and micro- scopical lesions of tuberculosis as well as mycobacterial colonization, primarily affecting the lungs and lung associated lymph nodes. Specific cell-mediated and antibody responses, including kinetics of the response, as well as antigen recognition profiles, were also comparable between the two treatment groups. Present findings demonstrate that M. bovis strains 95-1315 and 10-7428 have similar virulence when administered to cattle via aerosol inoculation. Other factors such as livestock management practices likely affected the severity of the outbreak in the dairy. Published by Elsevier Ltd. C1 [Waters, W. R.; Thacker, T. C.; Maggioli, M.

The disease is caused by the fastidious bacterium Xylella fastidiosa. We have tested seed extracted from fruit heavily infected and symptomatic for X. fastidiosa infection as well as seed obtained from normal asymptomatic fruit from the same trees in Brazil. Seeds from symptomatic fruit were tested by PCR and found to be contaminated with X. fastidosa, and to weigh less than seeds from normal-sized fruit. Seed from both symptomatic and asymptomatic fruit were sown in the greenhouse and studied following germination. The growth of shoots, but not of roots, was reduced in seedlings produced from seed collected from symptomatic as compared to asymptomatic fruits. Symptoms of citrus variegated chlorosis were not observed in any of the seedlings derived from seed from symptomatic and asymptomatic fruit. Roots and leaf midribs from 260 seedlings were tested for the presence of X. fastidiosa by PCR three months after sowing. No positive PCR results were observed. Leaf midribs from 148 seedlings were tested subsequently at 17 months after sowing using both standard format and qPCR assays, also without any positive results. Leaf midribs from 349 seedlings from a second seed harvest were tested seven months after sowing by qPCR also without any positive tests. Thus in this study no evidence for the vertical transmission of X. fastidiosa through contaminated seed was obtained. C1 [Hartung, J.

TI Efficacy of Plastic Mesh Tubes in Reducing Herbivory Damage by the Invasive Nutria (Myocastor coypus) in an Urban Restoration Site SO NORTHWEST SCIENCE LA English DT Article DE herbivory; Myocastor; non-native; riparian; Vexar ID WESTERN NORTH-AMERICA; STREAM RESTORATION; MAMMALIAN HERBIVORES; RIPARIAN ECOSYSTEMS; PACIFIC-NORTHWEST; SUCCESSION; MANAGEMENT; CORRIDORS; WETLANDS; HABITAT AB The restoration of stream corridors is becoming an increasingly important component of urban landscape planning, and the high cost of these projects necessitates the need to understand and address potential ecological obstacles to project success. The nutria (Myocastor coypus) is an invasive, semi-aquatic rodent native to South America that causes detrimental ecological impacts in riparian and wetland habitats throughout its introduced range, and techniques are needed to reduce nutria herbivory damage to urban stream restoration projects. We assessed the efficacy of standard Vexar (R) plastic mesh tubes in reducing nutria herbivory damage to newly established woody plants. The study was conducted in winter-spring 2009 at Delta Ponds, a 60-ha urban waterway in Eugene, Oregon. Woody plants protected by Vexar (R) tubes demonstrated 100% survival over the 3-month initial establishment period, while only 17% of unprotected plantings survived. Nutria demonstrated a preference for black cottonwood (Populus balsamifera ssp trichocarpa) over red osier dogwood (Cornus sericea) and willow (Salix spp). Camera surveillance showed that nutria were more active in unprotected rather than protected treatments. Our results suggest that Vexar (R) plastic mesh tubing can be an effective short-term herbivory mitigation tool when habitat use by nutria is low. Additionally, planting functionally equivalent woody plant species that are less preferred by nutria, and other herbivores, may be another method for reducing herbivory and improving revegetation success. This study highlights the need to address potential wildlife damage conflicts in the planning process for stream restoration in urban landscapes.

TI ULTRAPETALA trxG Genes Interact with KANADI Transcription Factor Genes to Regulate Arabidopsis Gynoecium Patterning SO PLANT CELL LA English DT Article ID TRITHORAX GROUP PROTEINS; FLORAL MERISTEM; LATERAL ORGANS; CONTROLS SHOOT; POLARITY; POLYCOMB; AUXIN; ESTABLISHMENT; SPATULA; MECHANISMS AB Organ formation relies upon precise patterns of gene expression that are under tight spatial and temporal regulation. Transcription patterns are specified by several cellular processes during development, including chromatin remodeling, but little is known about how chromatin-remodeling factors contribute to plant organogenesis. We demonstrate that the trithorax group (trxG) gene ULTRAPETALA1 (ULT1) and the GARP transcription factor gene KANADI1 (KAN1) organize the Arabidopsis thaliana gynoecium along two distinct polarity axes. We show that ULT1 activity is required for the kan1 adaxialized polarity defect, indicating that ULT1 and KAN1 act oppositely to regulate the adaxial-abaxial axis. Conversely, ULT1 and KAN1 together establish apical-basal polarity by promoting basal cell fate in the gynoecium, restricting the expression domain of the basic helix-loop-helix transcription factor gene SPATULA. Finally, we show that ult alleles display dose-dependent genetic interactions with kan alleles and that ULT and KAN proteins can associate physically. Our findings identify a dual role for plant trxG factors in organ patterning, with ULT1 and KAN1 acting antagonistically to pattern the adaxial-abaxial polarity axis but jointly to pattern the apical-basal axis. Our data indicate that the ULT proteins function to link chromatin-remodeling factors with DNA binding transcription factors to regulate target gene expression.

Even though its physiological function has already been investigated in different cell or mouse models where PrPC expression is either upregulated or depleted, its exact physiological role in a mammalian organism remains elusive. Recent studies indicate that PrPC has multiple functions and is involved in cognition, learning, anxiety, locomotion, depression, offensive aggression and nest building behavior. While young animals (3 months of age) show only marginal abnormalities, most of the deficits become apparent as the animals age, which might indicate its role in neurodegeneration or neuroprotection. However, the exact biochemical mechanism and signal transduction pathways involving PrPC are only gradually becoming clearer. We report the observations made in different studies using different Prnp0/0 mouse models and propose that PrPC plays an important role in the regulation of the cytoskeleton and associated proteins. In particular, we showed a nocodazole treatment influenced colocalization of PrPC and tubulin 1. In addition, we confirmed the observed deficits in nest building using a different backcrossed Prnp0/0 mouse line.

To better understand the potential for SOC storage in specific aggregate pools (e.g., physically protected intra-aggregate C), a wetsieving aggregate fractionation method was coupled with Fourier-transform mid-infrared (MidIR) spectroscopy to determine the composition of waterstable (macroaggregates, microaggregates, and silt + clay) and intra-aggregate (particulate organic matter [POM], microaggregates, and silt + clay) fractions under an integrated crop-livestock (ICL) system and continuous cotton (Gossypium hirsutum L.) production. These agroecosystems were located in the semiarid Texas High Plains on a clay loam soil. The ICL system included a paddock of grazed WW-B. Dahl Old World bluestem [Bothriochloa bladhii (Retz) S.T. Blake] and a no-till crop rotation of wheat (Triticum aestivum L.)-fallow-rye (Secale cereale L.)-cotton for livestock grazing and cotton production. Distance-based redundancy analysis (dbRDA) of the MidIR spectra distinguished the intra-aggregate POM from the other fractions. The intra-aggregate POM fraction was correlated with increased pseudo-absorbance (PA) in regions associated with carboxylates, phenolic C-O, aliphatic C-H, and quartz, while macro-and microaggregates demonstrated higher PA at 1570 and 1700 to 1765cm(-1). Differences attributed to management were identifiable in intra-aggregate POM and both silt + clay fractions. Within the intra-aggregate POM, dbRDA showed that bluestem was characterized by higher PA at 2800 to 3000 and 3300 to 3450 cm(-1) relative to the rest of the rotations. In the silt + clay fractions, more labile functional groups were found following rye and cotton planting.

Our objectives were to evaluate grain yield, soil organic C (SOC), and total soil N (0-150 cm) in a 10-yr, irrigated, continuous corn study under conventional disk tillage (CT) and notill (NT) with variable corn stover removal rates (none, medium, and high). Natural abundance C isotope compositions (delta C-13) were used to determine C additions by corn (C-4-C) to the soil profile and to evaluate the retention of residual C-3-C. After 10 yr of management treatments, mean grain yields were 7.5 to 8.6% higher for NT when stover was removed compared with no stover removal, while grain yields were similar for CT in all stover removal treatments. Turnover of SOC occurred as C-3-C stocks were replaced by C-4-C in the 0- to 120-cm soil profile. Total SOC and N stocks changed mainly in surface soils (0-30 cm), with no detectable cumulative changes at 0 to 150 cm. Specifically, SOC declined after 10 yr under CT at 0 to 15 cm and was affected by residue management at 15 to 30 cm. Total soil N was greater when no stover was removed (P = 0.0073) compared with high stover removal at 0 to 15 cm. Long-term NT ameliorated medium stover removal effects by maintaining near-surface SOC levels. Results support the need to evaluate SOC cycling processes below near-surface soil layers.

The traditional peanut-cotton rotation (TR) often results in erosion and loss of soil organic carbon (SOC). Incorporation of bahiagrass (Paspalum notatum Fluegge) into the peanut-cotton rotation for 2 yr (also called a sod-based rotation or SBR) has been suggested for improving SOC, particularly in conjunction with conservation tillage practices. To determine the effect of the SBR on carbon sequestration, SOC and its isotopic composition were evaluated on established (>10 yr) crop rotation systems. Cropping systems evaluated included (i) TR under CT, (ii) TR under strip tillage (ST), (iii) SBR under CT, (iv) SBR under ST, and (v) SBR under ST with cattle grazing. Total SOC, bahiagrass-derived SOC, and potential C mineralization increased in the top 10 cm of soil, indicating the potential for ST to improve soil fertility in SBR systems. Grazing bahiagrass decreased SOC in the 5 to 10 cm depth, but this effect was not observed for the subsequent peanut crop and did not appear to have a long-term negative effect on SOC storage. The SBR did not show consistent improvements in total SOC compared with the TR. A 3-yr comparison of SOC concentration revealed C increases in SBR and TR systems, indicating that other conservation practices (e. g., winter cover cropping) are the primary contributors to SOC storage for Coastal Plain soils evaluated in this study. Isotopic analysis of mineralized CO2 indicated bahiagrass-derived SOC may be preferred over C-3 crop-derived SOC for degradation. C1 [Gamble, A. V.; Howe, J.

However, little attention has been given to estimating wind erodibility of soils in the region. The objective of this study was to determine the soil wind erodibility for four land use types in the Tarim Basin. Wind erodibility was determined from the dry aggregate size distribution of soils collected from desert, farmland, forest, and shrubland environments in spring 2013. Our analysis revealed that the percentage of soil mass composed of aggregates <840 mm in diameter (erodible fraction) ranged from 5.2 to 99.9% across sites with a mean of 58.9% across land use types. The four land use types had a high content of erodible aggregates. The mean percentage of soil mass which was comprised of saltation-size (500-100 mm in diameter) and suspension-size material (<100 mu m in diameter) was 15.0 and 39.0%, respectively, across land use types. The desert had the highest potential for saltation activity and suspension. Our results suggest that all land use types examined in this study have potential to contribute to the atmospheric dust load in the Tarim Basin and to transcontinental and transoceanic transport of dust.

However, soil C sequestration and ecosystem biodiversity have emerged as critical services provided by managed forest soils that must also be sustained. These ecosystem services were assessed in response to gradients of organic matter removal, soil compaction, and noncrop vegetation control on the thirteen 15-yr-old sites of the international Long-Term Soil Productivity (LTSP) study located in North Carolina, Mississippi, Louisiana, and Texas in the Atlantic and Gulf coastal plains of the southern United States. Whole-tree harvesting without removing the forest floor reduced tree volume at one site while removing the forest floor to achieve maximum nutrient removals reduced stand volume by 7% overall. Conversely, soil compaction increased pine volume production by 10% overall. Vegetation control increased pine stand volume production by 46% overall. Mineral soil C storage in the surface 0.3 m was similar overall regardless of treatment. Soil compaction and organic matter removal did not alter overall woody species richness or Shannon's Index of diversity. Overall, these results suggest that biomass harvesting and intensive organic matter removal from southern pine stands has limited and site-specific effects on three soil ecosystem services: timber volume production, mineral soil C storage, and woody plant diversity.

TI Soil Change Induced by Prairie Dogs across Three Ecological Sites SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID DEGRADED SHRUB-STEPPE; ECOSYSTEM; MOUNDS AB Prairie dogs (Cynomys spp.) can influence vegetation dynamics and landscape hydrology by altering soil properties, yet few studies have evaluated soil responses to prairie dog activities across a range of soil types. This study was conducted to quantify prairie dog effects on soil properties within three unique ecological sites differing in soil and landscape attributes on a 1400 ha ranch near McLaughlin, SD. Soil properties and infiltration rate were evaluated within thin claypan, loamy, and shallow loamy ecological sites corresponding to footslope, backslope, and summit-shoulder landscape positions, respectively. Prairie dog activity was found to influence soil properties similarly across ecological sites. Prairie dog activity contributed to considerable soil heterogeneity, with on-mound areas characterized as acidified, nutrient "hot spots" compared with off-mound areas. On-mound areas possessed faster infiltration rates than off-mound areas within loamy and shallow loamy ecological sites. Soil organic C was greater in on-mound areas compared with off-mound areas, but only at intermediate depths (10 to 30 cm). Results from this study suggest postextirpation restoration efforts should consider soil heterogeneity induced by prairie dog activity within and across ecological sites. C1 [Barth, C.

TI Evaluation of Elite Southern Maturity Soybean Breeding Lines for Drought-Tolerant Traits SO AGRONOMY JOURNAL LA English DT Article ID VAPOR-PRESSURE DEFICIT; NITROGEN-FIXATION; TRANSPIRATION EFFICIENCY; GENOTYPIC VARIATION; SOIL-WATER; L.; STRESS; VARIABILITY; SENSITIVITY; CULTIVARS AB Breeding efforts in soybean [Glycine max (L.) Merr.] have addressed the challenge of water-limited yields by incorporating parental stocks which exhibit drought-tolerant traits. Multiple cycles of empirical selection for improved yielding ability in water-deficient field environments have produced new generations of adapted breeding lines. However, the impact of this selection process on specific putative drought-tolerant traits is unknown. The objective of this study was to determine if breeders' selection of 10 elite lines for high seed yield under dry conditions is associated with the presence of physiological expression of three putative drought-tolerant traits: (i) limited transpiration rate under high vapor pressure deficit (VPD), (ii) early decrease in transpiration rate with soil drying, and (iii) drought-tolerant N-2 fixation. Greenhouse experiments were undertaken to characterize each genotypes for their phenotype of each of these three traits. Unlike most soybean cultivars, 9 of the 10 elite lines expressed a limited transpiration rate under elevated VPD. The VPD at which transpiration rate became limited was 1.9 kPa or less. There was no difference among genotypes in the threshold for decline in transpiration rate with soil drying, although all genotypes expressed high thresholds indicating an ability to conserve soil water. All lines expressed drought tolerance in their N-2 fixation rates, which was superior to that commonly observed in soybean. This study demonstrated that mating of parents that expressed a drought trait and multiple rounds of progeny selection based on improved yield under water-limited conditions resulted in the elite lines expressing improved drought traits.

TI Agronomic Factors Affecting Dryland Grain Sorghum Maturity and Production in Northeast Colorado SO AGRONOMY JOURNAL LA English DT Article ID WHEAT TRITICUM-AESTIVUM; GROWTH-RESPONSES; WATER-USE; YIELD; LIGHT; APPEARANCE; DURATION AB Grain sorghum [Sorghum bicolor (L.) Moench] is an important dryland crop in southeastern Colorado, but expansion into northeastern Colorado is thought to be limited due to the shorter growing season. The study examined whether sorghum production could be expanded into northeastern Colorado. A 2-yr study in northeastern Colorado at Akron (2010, 2011), Fort Collins (2011), and Stratton (2010) investigated row orientation, seeding rate, and row spacing effects for three hybrids within early to medium-early maturity classes on the time to physiological maturity and grain yield. All treatments reached physiological maturity in the four trial environments. Hybrid selection and seeding rate significantly impacted the thermal time to reach physiological maturity. The medium-early hybrid (5745) matured significantly later than the early maturity hybrids (88P68 and DKS29-28). The seeding rate of 20 seeds m(-2) matured significantly earlier than 11 seeds m(-2), which matured much earlier than 3 seeds m(-2). Row orientation and row spacing did not influence maturity. Yields were generally acceptable across all environments, hybrids, and agronomic treatments, and average yields among environments ranged from 1690 to 4845 kg ha(-1). Probabilities of the hybrids reaching maturity were high at Akron and Stratton (at least 62 and 86%, respectively, for the latest simulated planting date), but low for Fort Collins (highest of 75% for the earliest simulated planting date). Grain sorghum can successfully be grown in northeast Colorado, especially if planting early maturity hybrids using 0.76 m row spacing at a seeding rate close to 11 seeds m(-2).

TI Potato Gas Exchange Response to Drought Cycles under Elevated Carbon Dioxide SO AGRONOMY JOURNAL LA English DT Article ID WATER-USE EFFICIENCY; SOLANUM-TUBEROSUM L.; CONTROLLED-ENVIRONMENT CHAMBERS; CO2 ENRICHMENT; ATMOSPHERIC CO2; GROWTH; YIELD; STRESS; PHOTOSYNTHESIS; IRRIGATION AB Elevated carbon dioxide (CO2) influences photosynthesis (A(N)), transpiration (ET), and water use efficiency (WUE) for well-watered potato (Solanum tuberosum L.). Little is known regarding effects of short-term drought and CO2. Two experiments, differing in the quantity of solar radiation, were conducted in soil-plant-atmosphere-research chambers. Plants were grown at ambient (aCO(2)) or twice-ambient CO2 (eCO(2)) and received one of three irrigation treatments: no water stress (C), short-term (11-16 d) water-withholding during vegetative and post-tuber initiation stages (VR), or post-tuber initiation (R) only. Canopy conductance to CO2 transfer (tau) and water vapor (G(v)), light use efficiency (alpha), daily A(N), and ET decreased at the onset of each drought and were correlated with volumetric water content. The rate of decrease was similar for R and VR. Gv declined more sharply than A(N), resulting in higher WUE. Seasonal A(N) declined with the pattern of C > R > VR and was higher for eCO(2) C and R treatments. Seasonal WUE was higher for eCO(2) at all irrigation treatments. Total dry matter, harvest index, and leaf area were reduced (p < 0.05) for droughted treatments and total dry matter and harvest index were also higher for eCO(2) VR pots. Relative responses to drought and CO2 were similar among experiments, with greater magnitude of response under high solar radiation. Findings were similar to those reported under longer-term water-withholding studies, suggesting that interactions between CO2 and drought on carbon assimilation and water use are conserved across production zones with varying radiation and rainfall patterns.

NUTRITIVE-VALUE; FORAGE PRODUCTION; DRY-MATTER; FIBER; ORCHARDGRASS; MANAGEMENT; WISCONSIN; TIMOTHY; MANURE; YIELD AB Previous research has shown that oat (Avena sativa L.) has promise as a fall-forage option for dairy producers. In addition, dairy producers often have a recurring need to identify opportunity windows for manure hauling other than before or after production of corn (Zea mays L.). Our objectives were to evaluate the effects of N fertilization, cultivar selection, and harvest date on dry matter (DM) yield, N uptake, N recovery, and the nutritive value of fall-grown oat forages fertilized with either urea (46-0-0) or bedded-pack manure obtained from a dairy-heifer facility. Two cultivars of oat (ForagePlus and Ogle) were planted in August 2011 and 2012, fertilized with bedded-pack manure (23 or 45 Mg ha(-1), wet basis) or commercial urea (46-0-0) at rates of 0, 20, 40, 60, or 80 kg N ha(-1), and then harvested on two dates. Climatic conditions differed sharply across years, with growth responses limited by droughty conditions during 2012. During both years, DM yield increased linearly with commercial N fertilization, although the magnitude of these responses was relatively small. Yields of DM following applications of urea exceeded those of forages receiving bedded-pack manure during 2011. Apparent N recoveries increased linearly with application rate for urea during 2011 and increased with both linear and quadratic effects during 2012, but N recoveries following applications of bedded-pack manures were minimal during both years (overall range = -6.2 to 2.6% of N applied). These results indicate that bedded-pack manures containing wood shavings provided little immediately available N to support production of fall-grown oat. C1 [Coblentz, W. K.; Jokela, W.

TI Predicting Maize Phenology: Intercomparison of Functions for Developmental Response to Temperature SO AGRONOMY JOURNAL LA English DT Article ID CORN GROWTH-RESPONSE; ZEA-MAYS-L; LEAF-APPEARANCE; SOWING DATE; PHOTOPERIOD; NUMBER; RATES; PRODUCTIVITY; MODEL; INITIATION AB Accurate prediction of phenological development in maize (Zea mays L.) is fundamental to determining crop adaptation and yield potential. A number of thermal functions are used in crop models, but their relative precision in predicting maize development has not been quantified. The objectives of this study were (i) to evaluate the precision of eight thermal functions, (ii) to assess the effects of source data on the ability to differentiate among thermal functions, and (iii) to attribute the precision of thermal functions to their response across various temperature ranges. Data sets used in this study represent >1000 distinct maize hybrids, >50 geographic locations, and multiple planting dates and years. Thermal functions and calendar days were evaluated and grouped based on their temperature response and derivation as empirical linear, empirical nonlinear, and process-based functions. Precision in predicting phase durations from planting to anthesis or silking and from silking to physiological maturity was evaluated. Large data sets enabled increased differentiation of thermal functions, even when smaller data sets contained orthogonal, multi-location and -year data. At the highest level of differentiation, precision of thermal functions was in the order calendar days < empirical linear < process based < empirical nonlinear. Precision was associated with relatively low temperature sensitivity across the 10 to 26 degrees C range. In contrast to other thermal functions, process-based functions were derived using supra-optimal temperatures, and consequently, they may better represent the developmental response of maize to supra-optimal temperatures. Supra-optimal temperatures could be more prevalent under future climate-change scenarios, but data sets in this study contained few data in that range.

Adoption rates during 2009 to 2011 were higher without manure; almost one-half of respondents adopted N rate guidelines for AC and about one-third adopted for ACC. With manure, adoption decreased to only 29% for AC and 25% for ACC. In all cases, the odds of nonadoption increased when corn followed fair or good alfalfa stands relative to poor stands. In most cases, the odds of nonadoption also increased when corn yield goal was used as a factor for determining fertilizer N rates for AC and ACC. Nonadoption of N rate guidelines in AC increased the odds of nonadoption in ACC, whether manure was applied or not. Respondents' past experience and soil testing lab recommendations were rated as the most reliable information sources for N management. The high frequency and rate of excess N application in this rotation highlights a pressing need for enhanced research and stakeholder engagement to increase adoption of alfalfa and manure N credits. In particular, there is a need to discourage manure applications to AC and ACC, which often require little or no applied N beyond alfalfa N credits. Efforts should involve multiple stakeholders and may require improved, more site-specific, N rate guidelines for AC and ACC.

TI A Stochastic Approach for Predicting the Profitability of Bioenergy Grasses SO AGRONOMY JOURNAL LA English DT Article ID ENERGY CROPS; PANICUM-VIRGATUM; CLAYPAN SOILS; UNITED-STATES; SWITCHGRASS; YIELD; MODEL; LANDSCAPES; MISCANTHUS; TENNESSEE AB Switchgrass (Panicum virgatum L.) and miscanthus (Miscanthus x giganteus) have potential to meet a growing demand for renewable energy feedstock. Before producers will invest in planting these crops, they need credible estimations of the potential profits. The objective of this study was to examine profitability of growing these perennial bioenergy grasses, incorporating uncertain prices and yields in the model. The model compared the profitability of five crops {switchgrass, miscanthus, corn [Zea mays L.], soybean [Glycine max (L.) Merr.] and tall fescue pasture [Festuca arundinacea]} on three soil profiles common in northeastern Missouri: an upland, noneroded soil, an eroded soil, and floodplain soil. The effect of the USDA Biomass Crop Assistance Program (BCAP) and crop insurance on the decision to grow switchgrass and miscanthus was analyzed. Actual grain yields, Agricultural Land Management Alternatives with Numerical Assessment Criteria (ALMANAC) modeled grass yields, and Food and Agricultural Policy Research Institute (FAPRI) baseline prices were used to simulate profit. The results were compared using cumulative distribution functions (CDFs). Corn production was always chosen by decision makers of all risk attitudes to other crops. Miscanthus was always more profitable than switchgrass. Based on the CDFs, perennial bioenergy grasses were more likely to be planted in eroded soils currently in pasture production; however, there were scenarios in which they could be planted on eroded cropland currently planted to soybean. Lastly, crop insurance for corn and soybean could affect the decision to plant perennial bioenergy grasses for risk averse producers.

Canopy reflectance can be used to describe crop status and yield spatial variability. The objectives of this work were to understand the spatiotemporal variability of maize (Zea mays L.) yield using ground-based reflectance acquisitions in a salinity-and water-stress-affected 21-ha field beside the Venice Lagoon, Italy. Intra-and interannual reflectance variations were analyzed across the entire field and at each map cell with time to understand how the different soil-related stresses (i.e., salinity and water) arise under different meteorological conditions. The results show that the normalized difference vegetation index (NDVI) acquired during the maize flowering and kernel maturation stages (during the three growing seasons of 2010, 2011, and 2012) effectively described yield spatiotemporal variability. In particular, stressed areas exhibited the smallest changes in NDVI during a single growing season. Soil salinity and water stress were responsible for approximately 44% of the intra-annual NDVI change. When multiyear NDVI data are compared, areas affected by soil salinity show the smallest temporal variability. Nevertheless, areas that are slightly saline and constantly affected by water stress could not be distinguished from highly saline areas. Multiyear reflectance data can be a useful tool to characterize areas where soil salinity is the main factor limiting crop production. In areas where several plant stresses occur simultaneously every year, the proposed approach could be used to guide precision irrigation to make adjustments for within-field leaching requirement and/or irrigation needs.

We studied the 15-yr cumulative effects of narrow and perennial switchgrass (Panicum virgatum L.) barriers on soil organic C (SOC), total N, particulate organic matter (POM), and associated soil structural properties as compared with the cropped area on an Aksarben silty clay loam (fine, smectitic, mesic Typic Argiudoll) with 5.4% slope in eastern Nebraska. Five switchgrass barriers were established in 1998 at similar to 38-m intervals parallel to the crop rows in a field under a conventional tillage and no-till grain sorghum [Sorghum bicolor (L.) Moench]-soybean [Glycine max (L.) Merr.]-corn (Zea mays L.) rotation. Compared with the cropped area, switchgrass barriers accumulated about 0.85 Mg ha(-1) yr(-1) of SOC and 80 kg ha(-1) yr(-1) of total soil N at the 0 to 15 cm soil depth. Switchgrass barriers also increased coarse POM by 60%. Mean weight diameter of water-stable aggregates increased by 70% at 0 to 15 cm and by 40% at 15 to 60 cm, indicating that switchgrass barriers improved soil aggregation at deeper depths. Large (4.75-8 mm) macroaggregates under switchgrass barriers contained 30% more SOC than those under the cropped area. Switchgrass-induced changes in SOC concentration were positively associated with aggregate stability (r = 0.89***) and porosity (r = 0.47*). Overall, switchgrass barriers integrated with intensively managed agroecosystems can increase the SOC pool and improve soil structural properties.

L. TI Yield and Yield Gaps in Central US Corn Production Systems SO AGRONOMY JOURNAL LA English DT Article ID MAIZE PRODUCTION; SOUTHEAST-ASIA; AGRICULTURE; CLIMATE; TRENDS; CHINA; POTENTIALS; MANAGEMENT; TOLERANCE; PLAIN AB The magnitude of yield gaps (YGs) (potential yield -farmer yield) provides some indication of the prospects for increasing crop yield. Quantile regression analysis was applied to county corn (Zea mays L.) yields (1972-2011) from Kentucky, Iowa, and Nebraska (irrigated) (total of 115 counties) to estimate the attainable potential yield (APY) (yield in the most favorable environments in the 40-yr record) for each county. The YG for each year was the difference between the APY and the county yield. Potential productivity (40-yr mean county yield) varied substantially within and among states (579-1001 g m(-2)). The mean relative yield gap (RYG) varied from 9 to 24% of APY and decreased linearly (p < 0.0001) as the mean county yield increased for each state. Large YGs were partially related to very low yields that occurred in some years and may reflect the ability of the soil to supply water to the crop; other soil or management factors may also be involved since irrigation did not reduce the RYG in Nebraska to zero. The highest mean county APY was 30% (Kentucky), 22% (Iowa) and 14% (Nebraska) higher than the lowest county APY. This second YG occurred in favorable environments. Reducing the first YG in Kentucky and Iowa will probably require irrigation. Reducing the second YG may be more difficult if it is related to intractable soil characteristics. These results suggest that soil conditions may play an important role in determining the size of YGs in Midwestern corn production systems. C1 [Egli, D.

TI Evaluation of a Landscape-Scale Approach to Cotton Modeling SO AGRONOMY JOURNAL LA English DT Article ID TEXAS HIGH-PLAINS; TOPOGRAPHICALLY COMPLEX LANDSCAPES; WATER-USE; TERRESTRIAL BIOSPHERE; CARBON BALANCE; LINT YIELD; SOIL; IRRIGATION; EVAPOTRANSPIRATION; CONDUCTIVITY AB The Texas Southern High Plains is a semiarid region for cotton (Gossypium hirsutum L.) production that uses irrigation water from the Ogallala Aquifer, where depletion exceeds recharge, prompting limits to pump water. Thus, there is a need for management strategies to optimize the diminishing water, and these could be modeled provided the spatiotemporal variability associated with irrigated cotton production is captured. The Precision Agricultural-Landscape Modeling System (PALMS) is a grid-based model that accounts for variability across complex landscapes but lacked a cotton model. Our objective was to integrate the Cotton2K model with PALMS to produce PALMScot and to compare calculated values of soil water storage obtained with PALMScot to field-measured values for 2 yr and two irrigation treatments at two locations with contrasting soils, a fine sandy loam near Lamesa, TX, and a clay loam near Bushland, TX. Two statistics, mean absolute difference (MAD) and modified coefficient of efficiency (E-1) were used to compare differences between measured and calculated values of soil water content. In both years, MAD was <5% in the Amarillo and <10% in the Pullman soils and E-1 was 0.2 in the Amarillo and 0.4 in the Pullman soils, supporting the accuracy of the calculated values. Within the 1.4-m profile of both soils, however, the model overestimated root water uptake in the surface horizon and underestimated it in deeper ones. Our evaluation implied that PALMScot is a tool that can be used to track spatial and temporal variability of soil water storage across a complex landscape. C1 [Booker, J.

TI Crop Water Productivity of Sugarbeet as Affected by Tillage SO AGRONOMY JOURNAL LA English DT Article ID NORTHERN GREAT-PLAINS; IRRIGATION FREQUENCY; PHYSICAL-PROPERTIES; DEFICIT IRRIGATION; USE EFFICIENCY; STRIP TILLAGE; CONSERVATION; QUALITY; CLIMATE; SYSTEM AB One of today's greatest challenges of irrigated agriculture is to produce more food and fiber with less water, which can be accomplished by maximizing crop water productivity (CWP). A study was conducted to evaluate and compare the effect of conventional tillage (CT) and strip tillage (ST) on crop water use (CWU) and CWP of sugarbeet (Beta vulgaris L.) on clay loam soil in the northern Great Plains (NGP). Seasonal CWU and CWP for sugarbeet root and sucrose yields were determined for the 2006, 2007, and 2008 growing seasons according to the water balance and CWP equations under CT and ST practices. No significant differences due to tillage were found for CWU of sugarbeet. In 2006, CWP for root yield was significantly greater in ST relative to CT due to wind damage early in the spring which reduced sugarbeet plant population in the CT. The mean CWP for root yield across three growing seasons was10% greater for ST than for CT due to the protected soil-plant environment under the ST. The ST greatly reduces wind erosion and the related plant damage. The ST system used 0.0093 m(3) and 0.061 m(3) of irrigation water less than CT system to produce 1 kg of sugarbeet root and 1 kg of sucrose yield, respectively, throughout the growing season. We concluded that ST can be used to produce sugarbeet root yield and CWP comparable to CT or even in some instances greater than CT in areas that are prone to wind damage to sugarbeet seedlings.

In this work, Populus trichocarpa and Salix genetic resources were cryopreserved using dormant scions as the source explant. OBJECTIVE: We quantified the recovery of cryopreserved materials that originated from diverse field environments by using either direct sprouting or grafting. MATERIALS AND METHODS: Scions (either at their original moisture content of 48 to 60% or dried to 30%) were slowly cooled to -35 degrees C, transferred to the vapor phase of liquid nitrogen (LNV, -160 degrees C), and warmed before determining survival. RESULTS: Dormant buds from P. trichocarpa clones from Westport and Boardman, OR had regrowth levels between 42 and 100%. Direct rooting of cryopreserved P. trichocarpa was also possible. Ten of 11 cryopreserved Salix accessions, representing 10 different species, exhibited at least 40% bud growth and rooting after 6 weeks when a bottom-heated rooting system was implemented. CONCLUSION: We demonstrate that dormant buds of P. trichocarpa and Salix accessions can be cryopreserved and successfully regenerated without the use of tissue culture.

We use historical annual data of real U.S. gasoline prices, agricultural total factor productivity (TFP), real GDP, real agricultural exports, and real agricultural commodity price from 1948 to 2011 to estimate the model. Our results indicate that an energy price shock has a negative impact on productivity growth in the short run (1 year). An energy price shock and an agricultural productivity shock each account for about 10% of U.S. agricultural commodity price volatility with the productivity shock's contribution slightly higher. However, the impact from energy prices outweighs the contribution of agricultural productivity in the medium term (3 years). With more persistent impacts, energy shocks contribute to most (about 15%) of commodity price's variation in the long run. Published by Elsevier B.V.

Yang, Zhengwei Di, Liping Hunt, Kevin TI A New Automatic Stratification Method for US Agricultural Area Sampling Frame Construction Based on the Cropland Data Layer SO IEEE JOURNAL OF SELECTED TOPICS IN APPLIED EARTH OBSERVATIONS AND REMOTE SENSING LA English DT Article DE Area sampling frame (ASF); automated stratification; cropland data layer (CDL); cultivated data layer; land cover-based stratification ID STATISTICS AB This paper, for the first time, proposes to apply USDA National Agricultural Statistics Service (NASS) Cropland Data Layer (CDL) geospatial data for stratifying U.S. agricultural land. Anew automated method is proposed to stratify the NASS state level area sampling frames (ASFs) by automatically calculating percent cultivation at the primary sampling unit (PSU) level based on the CDL data. The NASS CDLs are 30-56.0 m raster-formatted, georeferenced, cropland cover classifications derived from satellite data. The CDL stratification experiment was successfully conducted for Oklahoma, Ohio, Virginia, Georgia, and Arizona. The stratification accuracies of the traditional (visual interpretation) and new automated CDL stratification methods were compared based on 2010 June Area Survey data. Experimental results indicated that the CDL stratification method achieved higher accuracies in the intensively cropped areas, while the traditional method achieved higher accuracies in low or nonagricultural areas. The differences in the accuracies were statistically significant at a 95% confidence level. It was found that using multiyear composite, CDL-based cultivated layers did not improve stratification accuracies as compared to the results of single-year CDL data. Two applications of the CDL-automated stratification method in official USDA NASS operations are described. The novelty of the proposed method was using geospatial CDL data to objectively and automatically compute percent cultivation of the ASF PSUs as compared to the traditional method that subjectively determines percent cultivation using visual interpretation of satellite data. This proposed new CDL-based process improved efficiency, objectivity, and accuracy as compared to the traditional stratification method.

This paper examines the influence of viewing and illumination angular effects on surface reflectance of typical surface and crop types for both narrow swath (e.g., Landsat) and wide swath (e.g., AWiFS) sensors. Three types of angular effects: 1) view angle effect; 2) day of year effect; and 3) mean local time drift effect were analyzed based on both field and satellite bi-directional reflectance distribution function (BRDF) measurements. In order to correct these angular effects, a BRDF look-up map (LUM) for major cover types was built using the cropland data layer (CDL) and the Moderate-Resolution Imaging Spectroradiometer (MODIS) BRDF products. The BRDF LUM was applied to an AWiFS image to correct view angle effects in an agricultural area in central Illinois. The resulting nadir BRDF-adjusted reflectance (NBAR) provides a consistent data source for intra-annual crop condition monitoring and inter-annual time-series analysis.

The traditional data distribution method cannot fully meet users' on-demand geospatial data needs. This paper presents interoperable, standard-compliant Web services developed for geospatial data access, query, retrieval, statistics, mapping, and comparison. Those standard geospatial web services can be integrated in scientific work-flows to accomplish specific tasks or consumed over the Web to create value-added new geospatial application by users. In addition, this paper demonstrates, via real world use cases, applications of those services and potential impacts on facilitating geospatial Cropland Data Layer (CDL) retrieval, analysis, visualization, dissemination and integration in agricultural industry, government, research, and educational communities. This paper also shows that the geospatial Web service approach helps improve the reusability, interoperability, dissemination, and utilization of agricultural geospatial data. It allows for integrating multiple online applications and different geospatial data sources, and enables automated retrieving and delivery of agricultural geospatial information for decision-making support.

The objective of this study was to compare information obtained from two different pixel sizes, one about a meter (the size of a small vegetation plot) and one about a millimeter. Cereal rye (Seeale eereale) was planted at the Beltsville Agricultural Research Center for a winter cover crop with fall and spring fertilizer applications, which produced differences in biomass and leaf chloroph 11 content. UAS imagery was simulated by placing a Fuji IS-Pro UVIR digital camera at 3-m height looking nadir. An external UV-IR cut filter was used to acquire true-color images; an external red cut filter was used to obtain color-infrared-like images with bands at near-infrared, green, and blue wavelengths. Plot-scale Green Normalized Difference Vegetation Index was correlated with dry aboveground biomass (r = 0.58), whereas the Triangular Greenness Index (TGI) was not correlated with chlorophyll content. We used the SamplePoint program to select 100 pixels systematically; we visually identified the cover type and acquired the digital numbers. The number of rye pixels in each image was better correlated with biomass (r = 0.73), and the average TGI from only leaf pixels was negatively correlated with chlorophyll content (r = 0.72). Thus, better information for crop requirements may be obtained using very small pixel sizes, but new algorithms based on computer vision are needed for analysis. It may not be necessary to geospatially register large numbers of photographs with very small pixel sizes. Instead, images could be analyzed as single plots along field transects. C1 [Hunt, E.

Although the concept of healthy lifespan needs to be defined better, we know that cardiovascular diseases (CVDs) are the main age-related diseases. Thus, controlling risk factors will contribute to reducing their incidence, leading to healthy lifespan. CVDs are complex diseases influenced by numerous genetic and environmental factors. Numerous gene variants that are associated with a greater or lesser risk of the different types of CVD and of intermediate phenotypes (i.e., hypercholesterolemia, hypertension, diabetes) have been successfully identified. However, despite the close link between aging and CVD, studies analyzing the genes related to human longevity have not obtained consistent results and there has been little coincidence in the genes identified in both fields. The APOE gene stands out as an exception, given that it has been identified as being relevant in CVD and longevity. This review analyzes the genomic and epigenomic factors that may contribute to this, ranging from identifying longevity genes in model organisms to the importance of gene-diet interactions (outstanding among which is the case of the TCF7L2 gene).

(n-3) Polyunsaturated fatty acids provide various health benefits, but there is a concern that they might increase lipid peroxidation. We examined the effects of docosahexaenoic acid [22:6 (n-3)] supplementation on lipid peroxidation markers in plasma and red blood cells (RBC) and their associations with red blood cell and plasma fatty acids. Hypertriglyceridemic men (n = 17 per group) aged 39-66 years participated in a double-blind, randomized, placebo-controlled, parallel study. They received no supplements for the first 8 days and then received 7.5 g/day docosahexaenoic acid oil (3 g/day docosahexaenoic acid) or olive oil (placebo) for 90 days. Fasting blood samples were collected 0, 45, and 91 days after supplementation. Docosahexaenoic acid supplementation did not change plasma or RBC concentrations of lipid peroxidation markers (total hydroxyoctadecadienoic acid, total hydroxyeicosatetraenoic acid, total 8-isoprostaglandin F2 alpha, 7 alpha-hydroxycholesterol, 7 beta-hydroxy-cholesterol) when pre- and post-supplement values were compared. However, the post-supplement docosahexaenoic acid (DHA) concentration was inversely associated with RBC concentrations of ZE-HODE, EE-HODE, t-HODE, and total 8-isoprostaglandin F2 alpha, (p<0.05). RBC concentration of hydroxycholesterol was also inversely associated with DHA but it did not attain significance (p = 0.07). Our results suggest that increased concentration of DHA in RBC lipids reduced lipid peroxidation. This may be another health benefit of DHA in addition to its many other health promoting effects.

All extracts were assayed for total phenolic content and free radical scavenging capacities by multiple colorimetric assays along with cellular antioxidant activity (CAA) and antiproliferative activity. Ferulic acid was the predominant phenolic acid in all 10 wheat bran samples with concentration ranging between 1.1 and 1.7 mg/g. The concentrations of lutein, zeaxanthin, and beta-carotene ranged between 1.0-1.4,0.2-0.3, and 0.1-0.2 mu g/g, respectively. Significant amount of a.-tocopherol (2.3-5.3 mu g/g) was quantified in all bran samples along with minor quantity of delta-tocopherol (similar to 0.1 mu g/g). No significant correlation between ferulic acid, tocopherol and carotenoid content and in vitro antioxidant radical scavenging assays or total phenolic content was observed. The Jamestown wheat bran demonstrated significant antiproliferative activities against both HT-29 and Caco-2 colon cancer cells at concentration of 50 mg bran equivalent (BE)/mL.

TI Selected vitamins, minerals and fatty acids in infant formulas in the United States SO JOURNAL OF FOOD COMPOSITION AND ANALYSIS LA English DT Article DE Infant formula; Minerals; Vitamins; National sampling; Calcium; Iron; Choline; Essential fatty acids; Food labeling standards; Food composition; Food analysis ID MILK; CHOLINE; FOODS AB Infant formulas (IF) are consumed during a short but critical growth period and are the sole source of nutrition for at least part of this time for non-breastfed infants. The 1980 Infant Formula Act (IFA) and subsequent legislation mandate fortification of all IF at specific levels of vitamins and minerals; manufacturers must assure these levels in their products. In order to determine the actual amounts of nutrients in IF and to determine how closely these conform to the IFA and labels amounts, fifteen highly consumed milk- or soy-based infant formulas were sampled nationally at 12 retail locations. These IF were analyzed, and thiamin, vitamins C, A, D, E and K, choline, calcium, iron, and arachidonic, docosohexanoic and linoleic acids values examined. Within analytical uncertainty, all IFs except linoleic acid in one formula met label claim and were within allowed ranges. These results suggest IFs provide nutrition at the level of the label or more. For some vitamins, there was substantially more present in the formula than the label amount, e.g. vitamin C, 25 +/- 16 vs. 8 mg per 100 kcal (n = 20), but the variability among brands was high. These data help researchers and consumers understand the nutritional impact of formulas in the diet of infants. (C) 2014 Published by Elsevier Ltd.

TI Negative regulation of germination-arrest factor production in Pseudomonas fluorescens WH6 by a putative extracytoplasmic function sigma factor SO MICROBIOLOGY-SGM LA English DT Article ID FACTOR GAF; RHIZOSPHERE BACTERIA; AERUGINOSA; BIOSYNTHESIS; EXPRESSION; GENETICS; GENES; PCR AB Pseudomonas fluorescens WH6 secretes a germination-arrest factor (GAF) that we have identified previously as 4-formylaminooxyvinylglycine. GAF irreversibly inhibits germination of the seeds of numerous grassy weeds and selectively inhibits growth of the bacterial plant pathogen Erwinia amylovora. WH6-3, a mutant that has lost the ability to produce GAF, contains a Tn5 insertion in prtR, a gene that has been described previously in some strains of P. fluorescens as encoding a transmembrane regulator. As in these other pseudomonads, in WH6, prtR occurs immediately downstream of prtl, which encodes a protein homologous to extracytoplasmic function (ECF) sigma factors. These two genes have been proposed to function as a dicistronic operon. In this study, we demonstrated that deletion of prtl in WT WH6 had no effect on GAF production. However, deletion of prtl in the WH6-3 mutant overcame the effects of the Tn5 insertion in prtR and restored GAF production in the resulting double mutant. Complementation of the double prtIR mutant with prtl suppressed GAF production. This overall pattern of prtIR regulation was also observed for the activity of an AprX protease. Furthermore, reverse transcription quantitative real-time PCR analysis demonstrated that alterations in GAF production were mirrored by changes in the transcription of two putative GAF biosynthetic genes. Thus, we concluded that Prtl exerted a negative regulatory effect on GAF production, although the mechanism has not yet been determined. In addition, evidence was obtained that the transcription of prtl and prtR in WH6 may be more complex than predicted by existing models.

TI Risks associated with preweaning mortality in 855 litters on 39 commercial outdoor pig farms in England SO PREVENTIVE VETERINARY MEDICINE LA English DT Article DE Piglet mortality; Outdoor pig production; Risk analysis; Longitudinal study ID ANIMAL-WELFARE; MATERNAL-BEHAVIOR; RECORDED CAUSES; FARROWING HUTS; ATTITUDES; PIGLETS; PERFORMANCE; GROWTH; HERDS; BIRTH AB A prospective longitudinal study was carried out on 39 outdoor breeding pig farms in England in 2003 and 2004 to investigate the risks associated with mortality in liveborn preweaning piglets. Researchers visited each farm and completed a questionnaire with the farmer and made observations of the paddocks, huts and pigs. The farmer recorded the number of piglets born alive and stillborn, fostered on and off and the number of piglets that died before weaning for 20 litters born after the visit. Data were analysed from a cohort of 9424 liveborn piglets from 855 litters. Overall 1274 liveborn piglets (13.5%) died before weaning. A mixed effect binomial model was used to investigate the associations between preweaning mortality and farm and litter level factors, controlling for litter size and number of piglets stillborn and fostered. Increased risk of mortality was associated with fostering piglets over 24 h of age, organic certification or membership of an assurance scheme with higher welfare standards, farmer's perception that there was a problem with pest birds, use of medication to treat coccidiosis and presence of lame sows on the farm. Reduced mortality was associated with insulated farrowing huts and door flaps, women working on the farm and the farmer reporting a problem with foxes. (C) 2014 Elsevier B.V. All rights reserved.

TI Risk factors perceived predictive of ISA spread in Chile: Applications to decision support SO PREVENTIVE VETERINARY MEDICINE LA English DT Article DE Expert opinion; Risk-based surveillance; Decision support; Infectious salmon anemia ID INFECTIOUS-SALMON-ANEMIA; FARMED ATLANTIC SALMON; SALAR L.; VIRUS ISAV; SURVEILLANCE; OUTBREAKS; REEMERGENCE; DISEASE; HEALTH; MAINE AB Aquaculture is anticipated to be a critical element in future solutions to global food shortage. However, diseases can impede industry efficiency and sustainability. Consequently, diseases can and have led to dramatic re-structuring in industry or regulatory practices. The emergence of infectious salmon anemia (ISA) in Chile is one such example. As in other countries, many mitigations were instituted universally, and many incurred considerable costs as they introduced a new layer of coordination of farming activities of marine sites within common geographic areas (termed 'neighborhoods' or 'barrios'). The aggregate response led to a strong reduction in ISA incidence and impact. However, the relative value of individual mitigations is less clear, especially where response policies were universally applied and retrospective analyses are missing 'controls' (i.e., areas where a mitigation was not applied). Further, re-focusing policies around disease prevention following resolution of an outbreak is important to renew sustainable production; though, again, field data to guide this shift in purpose are often lacking. Expert panels can offer timely decision support in the absence of empirical data. We convened a panel of fish health experts to weight risk factors predictive of ISA virus (ISAV) introduction or spread between Atlantic salmon barrios in Chile. Barrios, rather than sites, were the unit of interest because many of the new mitigations operate at this level and few available studies examine their efficacy. Panelists identified barrio processing plant biosecurity, fallowing strategies, adult live fish transfers, fish and site density, smolt quality, hydrographic connection with other neighborhoods, presence of sea lice (Caligus rogercresseyi), and harvest vessel biosecurity as factors with the greatest predictive strength for ISAV virulent genotype ('HPR-deleted') occurrence. Fewer factors were considered predictive of ISAV HPR0 genotype ('HPR0') occurrence, with greatest strengths assigned to fish and site density, adult live fish transfers, and smolt facility HPR0 status. Field validation based on ISAV and risk factor occurrence after panel completion generally supports expert estimates, and highlights a few factors (e.g., broodstock HPR0 status) less conclusive in the original study. Results inform legislation, industry best management practices and surveillance design. Published by Elsevier B.V.

The soil morphological units were hypothesized to be indicative of distinct water table regimes. Water table fluctuations in the wells were characterized by their median and interquartile range of depth, proportion of time water table was present in the solum, and storage-discharge behavior of subsurface flow. Statistically significant differences in median, interquartile range, and presence of water table were detected among soil units. Threshold responses were identified in storage-discharge relationships of subsurface flow, with thresholds varying among soil units. These results suggest that soil horizonation is indicative of distinct groundwater flow regimes. The spatial distribution of water table across the catchment showed variably connected/disconnected active areas of runoff generation in the solum. The spatial distribution of water table and therefore areas contributing to stormflow is complex and changes depending on catchment storage.

TI The impact of overstory density on sapling height growth in the Missouri Ozarks: implications for interspecific differentiation during canopy recruitment SO CANADIAN JOURNAL OF FOREST RESEARCH LA English DT Article DE silviculture; regeneration; recruitment; differentiation; quantile ID EASTERN UNITED-STATES; INTERIOR BRITISH-COLUMBIA; SHADE TOLERANCE; OAK REGENERATION; TREE SEEDLINGS; SOUTHERN APPALACHIANS; REGRESSION QUANTILES; COMPETITION INDEXES; PLANT-COMMUNITIES; TRADE-OFFS AB Successful canopy recruitment is one of the most important components of sustainable forestry practices. For many desirable species in oak-dominated forests, insufficient sapling growth is a common limitation to successful recruitment. The objectives of this study were to (i) examine the impact of overstory density on sapling growth in the Missouri Ozarks, (ii) investigate the potential for overstory retention to promote compositional shifts via interspecific differences in sapling height growth, and (iii) compare the use of mean and near-maximum growth rates to quantify the impact of overstory density on sapling growth and height differentiation among species. We found that the periodic annual height increment of saplings decreased with increasing overstory density for all species groups in this study (red oaks (Quercus spp.), white oaks (Quercus spp.), hickories (Carya spp.), sassafras (Sassafras spp.), blackgum (Nyssa spp.), dogwood (Cornus spp.), red maple (Acer spp.), ashes (Fraxinus spp.), and elms (Ulmus spp.)). There was evidence of interspecific differentiation in growth rates during the sapling stage, and the observed differences were more pronounced at low overstory densities. Increasing overstory densities either reduced or eliminated the differences in growth among species. Although red oaks displayed the greatest maximum growth rates of all species under low overstory densities (<5 m(2)center dot ha(-1)), the growth advantage of red oaks was reduced with increasing overstory density. This may provide opportunities to shift species composition toward white oaks using partial harvesting regimes in the Missouri Ozarks. However, white oaks had little to no advantage in height growth over many competing species when overstory density exceeded about 10 m(2)center dot ha(-1). This implies that the probability of recruitment under overstory densities greater than about 10 m(2)center dot ha(-1) is likely to decline for all oaks in the Missouri Ozarks. We found that using the 90th quantile of height growth rates to evaluate the impact of overstory density on sapling growth had two potential advantages over using the mean growth rate: (i) it provided better models of the limiting effects of overstory density on sapling height growth, and (ii) the focus was on the growth rates of stems that were most likely to recruit into the canopy.

For 14 species planted in 45 harvest gap and closed canopy locations in a mesic northern hardwood forest community, Michigan, USA, we asked the following questions: (i) are species growth responses to light, nitrogen (N), or N form (ammonium vs. nitrate) related to their ecological distributions and phylogenies? and (ii) is there evidence of growth-based resource partitioning over measured resource gradients? Growth responses to the N form were consistent with both differences in uptake energy requirements between N forms and their availability through succession and across fertility gradients; height growth was negatively related to the species shade-tolerance score, especially in high light, i.e., shade-intolerant species responded to soil nitrate-N and shade-tolerant species responded to ammonium-N; fertile soil associated species responded to nitrate-N and infertile soil associated species to ammonium-N; and gymnosperms responded to ammonium-N and angiosperm responses varied. Modeled growth responses to resources showed only modest evidence for rank changes over resource gradients, with N contributing less to rank changes than light. Thus, growth responses to resources were accurately predicted by species ecology and (or) phylogeny; however, there was only modest support for the notion that growth-based resource partitioning underlies community-scale diversity in a northern hardwood forest.

Because such damages are expected to increase with changes in wildfire regimes, this calls for more effective wildfire mitigation and adaptation strategies. Wildfire adaptation options for forestland owners include purchasing wildfire insurance, which provides compensation to those insured if a wildfire damages their properties. We attempt to (i) identify factors that influence the decision of family forestland owners in the southern United States to purchase wildfire insurance for their forestlands via logistic regression using landowner survey data and (ii) examine the propensity of these landowners to purchase wildfire insurance under climate change. We find that landowners are much more likely to purchase wildfire insurance if they are female or well educated or if their land is not classed as heirs' property, has been hit by a hurricane, or has not been burned by wildfire previously. Because climate change is likely to alter future wildfire and hurricane activity in the region, more forestland owners are predicted to purchase wildfire insurance, although the magnitude of such an increase appears moderate under current market institutions. These results would be helpful for developing new wildfire insurance programs and increasing the participation of forestland owners in the wildfire insurance market.

This randomized controlled clinical trial was conducted to evaluate the effect of vitamin A on immune competence in early infancy. Results would provide a mechanistic basis for understanding the effect of this intervention on infant survival. Within 2 days of birth, infants born at one maternity clinic located in a poor slum area of Dhaka city were supplemented with either 50,000 IU vitamin A or placebo. Live attenuated oral polio vaccine (OPV) and BCG vaccine were provided after supplementation. Infants also receive diphtheria, pertussis, tetanus (TT), hepatitis B (HBV) and Haemophilus influenzae B vaccines (pentavalent combination) along with OPV at 6, 10 and 14 weeks of age. Infant thymus size, anthropometry, feeding practice and morbidity data were collected at regular interval. Infant blood samples were collected to determine T-cell-receptor excision circle (TREC), total, naive and memory T cells and mucosal targeting lymphocytes including Treg cells. TT-, HBV-, BCG- and OPV-specific T cell blastogenic, cytokine and plasma cell antibody responses were also measured. In 16 mo enrollment period, 306 newborns, equal number of boys and girls, were enrolled. similar to 95% completed the 4-month follow-up period. Baseline characteristics are presented here. Anthropometry and immune assays with fresh blood samples were completed immediately while stored samples were analyzed in single batches at the end of the trial. Connecting different aspects of immunological data in early infancy will help elucidate immune competence for protecting infection. (C) 2014 Elsevier Inc. All rights reserved.

The advent of new high-throughput marker systems offers the opportunity to expand the scope and depth of our investigation of diversity. Our objective was to analyze the genetic diversity of two populations of soft winter wheat (SW) adapted to the eastern United States. The historical population (HP) consisted of 187 lines released or developed from 1808 to 2005. The elite population (EP) consisted of 449 elite modern lines from the Ohio State University breeding program. The HP was genotyped with single nucleotide polymorphism (SNP) and diversity array technology (DArT) markers, while the EP was genotyped with DArTs. Population structure comprised of up to five subgroups was observed on the HP using either SNP or DArT markers and up to six subgroups on the EP. The subgroups could be partly explained by year of release (in HP), class (red versus white wheat) and pedigree (in the EP). Diversity appeared to increase with time; an estimated 11% of the genome exhibited a pronounced linear change over time, while evidence of more subtle changes abound. The DArT markers were associated with greater genome changes than SNP markers. Linkage disequilibrium (LD) that produced an r(2) of 0.2 or greater extended to about 5 cM in both populations. The extent of LD decay varied widely across the genome. In conclusion, SW in the eastern United States has a moderate level of structure, appears quite diverse, and diversity may be increasing.

The objective of this study was to use Insertion-Deletion (InDel) and single-nucleotide polymorphism (SNP) markers from the BARCBean6K_3 Beadchip to identify quantitative trait loci (QTL) associated with traits related to leafhopper resistance in common bean. Traits for leaf curl and leaf burn damage, as well as Empoasca spp. nymph counts, were evaluated in an inbred backcross line population (Matterhorn*/EMP507) of beans in temperate (Michigan) and tropical (Puerto Rico) climates. Fourteen QTL associated with resistance to E. fabae and E. kraemeri were identified on five chromosomes explaining up to 66.0% of the phenotypic variation for single resistance traits. A major QTL cluster associated with multiple resistance traits and closely linked to the P color gene was detected for both leafhopper species in multiple seasons under both choice and no-choice treatments on Pv07 (LH7.1, LH7.2, LH7.3), thus validating a similar QTL identified in previous studies. A novel QTL (LH2.2) for E. fabae nymph counts, identified on Pv02 in three seasons, may be associated with antibiosis resistance. Resistance to each leafhopper species appears to be controlled by separate genetic mechanisms in common bean as there was little overlap of QTL regions between species. These QTL could be used to develop beans with leafhopper resistance as an alternative to costly chemical controls while reducing risks to the environment and human health.

Huangcandou (HCD) is a Chinese wheat landrace that shows a high level of resistance to FHB spread within a spike (type II). To identify quantitative trait loci (QTLs) for FHB resistance in HCD, 190 recombinant inbred lines (RILs) were developed from HCD x 'Jagger'. Jagger is a susceptible hard winter wheat from Kansas. The population was evaluated for the percentage of symptomatic spikelets (PSSs) per spike after single-floret inoculation in three greenhouse experiments. Initial marker screening identified 261 polymorphic simple sequence repeats (SSRs) between the parents. Analysis of these markers in the RIL population identified five QTLs, three from HCD and two from Jagger chromosomes. Two of the three QTLs from HCD were mapped on the short arms of chromosomes 3B, one in the distal end (3BSd) and another near the centromere (3BSc); the third was on the short arm of 3A (3AS). The QTL on 3BSd coincides with the previously reported Fhb1 and explained 26.1% of phenotypic variation. The QTL on 3AS explained up to 10.0% of phenotypic variation. The two QTLs from Jagger on chromosomes 2D and 6D explained 9.5% and 6.7% of phenotypic variations, respectively. A combination of QTLs from HCD and Jagger can enhance FHB type II resistance in wheat. C1 [Bai, Guihua] Kansas State Univ, Dept Agron, Manhattan, KS 66506 USA.

This manuscript documents the agronomic performance of the progeny of the diallel cross. Nine GEM germplasm lines and six known resistant and susceptible lines were selected as parents of a diallel cross that was evaluated over 2 yr at Mississippi State, MS, and 1 yr at College Station, TX. Mp317, Mp494, NEI9008, and GEMN-0130 had positive and significant GCA effects for yield in at least two of the three environments. This is especially useful because prior research suggested that both Mp494 and GEMN-0130 also reduce aflatoxin accumulation. Of the GEM lines evaluated, NEI9008 was the best source for enhanced yield with significant and positive GCA values across all three environments. Mp313E. GEMN-0157 yielded well across all environments with an additional benefit of relatively low aflatoxin accumulation in the Mississippi environments. Because the GEM lines evaluated in this diallel cross have a distinctly different genetic background than the aflatoxin-resistant Mississippi inbreds, NEI9008 and GEMN-0130 (improved yield), GEMS-0002 and GEMS-0074 (earlier maturity by 3 to 4 d), CUBA117, GEMS-0030, GEMN-0071, GEMS-0100 (reduced plant height 0.1 to 0.2 m), GEMN-0157, NEI9008, GEMS-0002, and GEMS-0074 (reduced height by 0.3 to 0.4 m) should be useful sources of alleles for pyramiding improved yield, earlier maturity, and shorter plant heights into improved breeding lines.

Merr.] grain production in the United States. Soybean cultivars with resistance are currently being deployed to aid in management of the pest. Temperature has been reported to influence the expression of host plant resistance against crop pests. The objective of this study was to determine if temperatures, 14, 21, and 28 degrees C, altered resistance expression in four aphid-resistant soybean genotypes, LD05-16611 (with the Rag1 resistance gene), PI 200538 (Rag2), PI 567541B (rag1c, rag4), and PI 567597C (antixenosis) compared to a susceptible soybean genotype (Williams 82) when challenged with soybean aphid. A replicated no-choice experiment was conducted and aphid populations of the three soybean aphid biotypes, 1, 2, and 3, were enumerated 14 d after inoculating the five soybean genotypes. Significant interactions were found in the analysis of the effects of temperature, soybean genotype, and aphid biotype on aphid populations. Responses between soybean genotypes and aphid biotypes were consistent with previous reports with the exception of PI 567541B, which had lower resistance against aphid biotype 1 than found in an earlier study. At 14 degrees C, there was limited aphid population growth on all soybean genotypes, including Williams 82. At 21 and 28 degrees C, resistance expression was stable in LD05-16611 (Rag1), PI 567541B (rag1c, rag4), and PI 567597C (antixenosis), relative to susceptible Williams 82; however, resistance expressed in PI 200538 (Rag2) was significantly stronger at 28 degrees C than at 21 degrees C, as indicated by differences in aphid population size that were found. Results of this study indicated that soybean aphid virulence variability had a stronger influence on the effectiveness of soybean aphid resistance than did temperature, and that the aphid resistance tested in this study would remain stable or be stronger in temperatures ranging between 21 and 28 degrees C.

Correlatively Expressed Functional Amino Acids SO CROP SCIENCE LA English DT Article ID GERMPLASM ENHANCEMENT; NUTRITIONAL QUALITY; HIGHER-PLANTS; METHIONINE; LYSINE; TRYPTOPHAN; CULTIVARS; TRAITS; SPECTROSCOPY; POPULATION AB Modern maize (Zea mays L.) breeding and selection for large starchy kernels may have contributed to reduced contents of essential amino acids, including lysine, methionine, and cysteine, which represents a serious nutritional problem. We evaluated 1348 maize accessions classified into 13 populations and derived from crossing exotic, high-quality maize landraces with Corn Belt stiff-and non-stiff-stalk heterotic groups. We used multivariate statistical analyses methods and validated partial least squares regression and structural equation models to study the homeostasis of these amino acids in relation to other phytochemicals in the maize kernel. New insights into the relative importance of several phytochemicals were derived from structural equation modeling, indicating that biochemical and physical constituents had negative impacts on amino acid contents regardless of heterotic group or endosperm texture and that mineral nutrients had positive effects; whereas, color space descriptors had mixed effects depending on heterotic group and endosperm texture. It was possible to develop quality protein germplasm with large lysine (4.2 g kg(-1) dry mass) content and opaque endosperm that resembles translucent endosperm, while the conversion from opaque to translucent endosperm was associated with minimal loss of lysine. Accessions derived from DKXL370-S11, DXKL370-N11a-N20, and 'Nokomis Gold' populations were identified as sources with high and stable contents of protein and all three amino acids, having either opaque or translucent endosperm textures.

Henn., abbreviated as Pgt) and other wheat (Triticum aestivum L.) diseases. To identify novel sources of resistance to Pgt race TTKSK (Ug99), we evaluated and characterized the stem rust resistance of 242 accessions belonging to five Thinopyrum species, including beach wheatgrass [Th. bessarabicum (Savul. & Rayss) A. Love], diploid tall wheatgrass [Th. elongatum (Host) D.R. Dewey], intermediate wheatgrass [Th. intermedium (Host) Barkworth & D. R. Dewey], sand cough or sea wheatgrass [Th. junceum (L.) A. Love], and decaploid tall wheatgrass [Th. ponticum (Podp.) Barkworth & D. R. Dewey]. These accessions were evaluated for seedling reactions to nine Pgt races (TTKSK, TTTTF, TRTTF, RTQQC, QFCSC, TCMJC, TPMKC, TMLKC, and TPPKC), genotyped with molecular markers linked to four stem rust resistance genes (Sr24, Sr25, Sr26, and Sr43) derived from Thinopyrum species, and examined for ploidy levels. All accessions but one (Th. elongatum PI 531718) were resistant to all or most races. Most of the Th. elongatum and Th. ponticum accessions showed near-immunity to all of the races while the accessions of the other three species (Th. bessarabicum, Th. intermedium, and Th. junceum) had varied levels of resistance ranging from near immunity to moderate resistance. Molecular marker analysis showed that most of the markers appeared to be species-or genus-specific rather than linked to a gene of interest, and thus genotyping analysis was of limited value. Comparisons of infection types of accessions based on ploidy level suggested that higher ploidy level was associated with higher levels of stem rust resistance. The results from this study substantiate that the Thinopyrum species are a rich source of stem rust resistance.

Merr.] breeding in the United States currently relies on a narrow genetic base. For decades, but more intensely in recent years, efforts have been made to incorporate exotic soybean germplasm into the breeding pool. Although wild soybean (G. soja Seib. and Zucc.) is genetically much more diverse than soybean, much less effort has been devoted to utilizing wild soybean in soybean breeding. The objectives of this research were to identify high-yielding lines derived from crosses between five wild soybean accessions and soybean cultivars and determine if there are differences in the genetic contributions of each wild soybean parent. Each wild soybean was crossed to Williams 82, and the F-1 plants were backcrossed to Williams 82 to create the backcross generation (BC 1) lines. The BC 2 parent lines were developed through family selection and backcrossed to Williams 82, IA2052, IA3023, or LN97-15076. Family selection beginning in the F-2 generation was used to develop lines from plant introduction (PI) 507807 and PI 549046. The lines from PI 479767 and PI 483461 were selected by early generation testing through yield testing F-2 lines in the F-3 and F-4 generations. The lines derived from PI 65549 were developed from a single seed descent (SSD) population. Field evaluation of the derived lines identified lines that are not significantly different from their recurrent parents. Using single nucleotide polymorphism (SNP) markers, we found unique contributions being made by the G. soja parents. Despite intense selection pressure to recover good agronomic types, an average of 13% of SNP alleles in the derived lines came from the G. soja parents.

Stem neutral detergent fiber (NDF), acid detergent lignin (ADL), and stem in vitro neutral detergent fiber digestibility (IVNDFD) are impacted by the environment. We identified 45 individual alfalfa plants that differed in stem NDF and ADL concentrations, ADL as a proportion of NDF (ADL/NDF), and stem IVNDFD after 16 and 96 h of digestion. All plants were vegetatively propagated and established in replicated trials and sampled 12 times (spring and early and late summer harvests for 2 yr at two field locations). A subset of clones were evaluated in two greenhouses and harvested for two regrowth cycles. Stability analyses demonstrated that stem ADL/NDF, NDF, and 96-h IVNDFD were more environmentally stable among the alfalfa clones in the field environments tested than stem 16-h IVNDFD or ADL. All stem fiber quality traits were considered consistent between the two field environments, but no relationship in trait responses were demonstrated between field and greenhouse environments. These results suggested that stem 96-h IVNDFD, NDF, and ADL/NDF would be the traits to use in a field selection program to develop alfalfa with improved nutrient value. C1 [Lamb, JoAnn F.

In many parts of Western Europe, North America, and Oceania fertilizers and feeds are relatively inexpensive, readily available and used abundantly to maximize profitable agricultural production. A case study, dairy systems approach was used to illustrate how differences in feed and manure management in a low-N-input dairy cattle system (Niger, West Africa) and a high-N-input dairy production system (Wisconsin, USA) impact agricultural production and environmental N loss. In Niger, an additional daily feed N intake of 114 g per dairy animal unit (AU, 1000 kg live weight) could increase annual milk production from 560 to 1320 kg AU(-1), and the additional manure N could greatly increase millet production. In Wisconsin, reductions in daily feed N intake of 100 g AU(-1) would not greatly impact milk production but decrease urinary N excretion by 25% and ammonia and nitrous oxide emissions from manure by 18% to 30%. In Niger, compared to the practice of housing livestock and applying dung only onto fields, corralling cattle or sheep on cropland (to capture urinary N) increased millet yields by 25% to 95%. The additional millet grain due to dung applications or corralling would satisfy the annual food grain requirements of 2-5 persons; the additional forage would provide 120-300 more days of feed for a typical head of cattle; and 850 to 1600 kg ha(-1) more biomass would be available for soil conservation. In Wisconsin, compared to application of barn manure only, corralling heifers in fields increased forage production by only 8% to 11%. The application of barn manure or corralling increased forage production by 20% to 70%. This additional forage would provide 350-580 more days of feed for a typical dairy heifer. Study results demonstrate how different approaches to feed and manure management in low-N-input and high-N-input dairy cattle systems impact milk production, manure N excretion, manure N capture, N recycling and environmental N loss.

Existing models are either unable to predict landslide size or are computationally intensive such that they cannot practically be applied across landscapes. We derive a model appropriate for natural slopes that is capable of predicting shallow landslide size but simple enough to be applied over entire watersheds. It accounts for lateral resistance by representing the forces acting on each margin of potential landslides using earth pressure theory and by representing root reinforcement as an exponential function of soil depth. We test our model's ability to predict failure of an observed landslide where the relevant parameters are well constrained by field data. The model predicts failure for the observed scar geometry and finds that larger or smaller conformal shapes are more stable. Numerical experiments demonstrate that friction on the boundaries of a potential landslide increases considerably the magnitude of lateral reinforcement, relative to that due to root cohesion alone. We find that there is a critical depth in both cohesive and cohesionless soils, resulting in a minimum size for failure, which is consistent with observed size-frequency distributions. Furthermore, the differential resistance on the boundaries of a potential landslide is responsible for a critical landslide shape which is longer than it is wide, consistent with observed aspect ratios. Finally, our results show that minimum size increases as approximately the square of failure surface depth, consistent with observed landslide depth-area data.

TI Solute Transport through a Pine Bark-based Substrate under Saturated and Unsaturated Conditions SO JOURNAL OF THE AMERICAN SOCIETY FOR HORTICULTURAL SCIENCE LA English DT Article DE breakthrough curve; cation exchange capacity; containerized crops; nitrate; phosphate; potassium ID CONTROLLED-RELEASE FERTILIZERS; POLYMER-COATED FERTILIZERS; NUTRIENT RELEASE; NITROGEN; MEDIA; BREAKTHROUGH; RETENTION; PATTERNS; LEACHATE; PH AB An understanding of how dissolved mineral nutrient ions (solutes) move through pine bark substrates during the application of irrigation water is vital to better understand nutrient transport and leaching from containerized crops during an irrigation event. However, current theories on solute transport processes in soilless systems are largely based on research in mineral soils and thus do not necessarily explain solute transport in soilless substrates. A study was conducted to characterize solute transport through a 9 pine bark:1 sand (by volume) substrate by developing and analyzing breakthrough curves (BTCs). Columns filled with pine bark substrate were subjected to the application of a nutrient solution (tracer) and deionized water under saturated and unsaturated conditions. Effluent drained from the columns during these applications was collected and analyzed to determine the effluent concentration (C) of the bulk ions in solution through electrical conductivity (EC) and nitrate (NO3-), phosphate, and potassium (K+) concentrations. The BTCs were developed by plotting C relative to the concentration of the input solution (C-o) (i.e., relative concentration = C/C-o) as a function of the cumulative effluent volume. Solutes broke through the column earlier (i.e., with less cumulative effluent) and the transition from C/C-o = 0 to 1 occurred more abruptly under unsaturated than saturated conditions. Movement of the anion, NO3-, through the substrate was observed to occur more quickly than the cation K. Throughout the experiment, 37% of the applied K+ was retained by the pine bark. The adsorption of K+ to pine bark cation exchange sites displaced calcium (Ca2+) and magnesium (Mg2+), of which the combined equivalent charge accounted for 43.1% of the retained K+. These results demonstrate the relative ease that negatively charged fertilizer ions could move through a pine bark substrate while solution is actively flowing through substrate pores such as during irrigation events. This approach to evaluating solute transport may be used in horticultural research to better understand how mineral nutrients move through and subsequently leach from soilless substrates during irrigation. Expanding this knowledge base may lead to the refinement of production practices that improve nutrient and water use efficiency in container nurseries.

Some fine-leaved Festuca grass species have been used in formal gardens and native urban landscapes because of their inherent tolerance to abiotic stresses, but native, ornamental types (tall and non-spreading with multicolored culms and panicles) are not common in landscapes of the western United States. A native fine-leaved Festuca collection made in Montana (designated FEID 9025897) by the U.S. Natural Resources Conservation Services possesses such ornamental characteristics but has not been evaluated for its horticultural potential. Therefore, a study was designed to assess its phenotypic and genotypic attributes by cloning 270 FEID 9025897 plants and evaluating them along with native F. idahoensis and F. ovina PIs (five) and commercial checks (five) for genetic diversity and plant morphology for 2 years (2010-11). Plant genetic constitution was determined using amplified fragment length polymorphism (AFLP) analysis. Plant height, width, biomass, relative vigor (visual rating of 0 = dead to 5 = green, abundant growth), persistence (number of plants alive per plot), and regrowth after clipping (visual rating of 0 = none to 5 = most) were estimated by evaluation of plants under replication at Hyde Park, UT. Based on AFLP-based coancestry analysis, FEID 9025897 plants possessed considerable genetic affinities with F. idahoensis. Morphological traits as averaged over both years varied in height (13.9 to 105.0 cm), width (9.9 to 66.2 cm), biomass (0 to 170.4 g), vigor (0.2 to 4.7), persistence (0 to 3.9), and regrowth (0 to 4.0). Based on these differences, 19 (7%) FEID 9025897 plants were identified for their ornamental potential that possessed multicolored (red, orange, and yellow) culms and varied in morphology with 2-year means of height (79.8 cm), width (45.2 cm), biomass (88.5 g), vigor (2.9), persistence (1.8), and regrowth (3.7).

Two genes encode E2-proteins with a single lipoyl domain, while the third has a two-lipoyl domain structure. Transcripts for each E2 protein were expressed in all plant organs. Each recombinant AtmtE2 can individually form an icosahedral PDC core structure, and results from bimolecular fluorescence complementation assays are consistent with formation of hetero-core structures from all permutations of the AtmtE2 proteins. We propose a unique regulatory mechanism involving dynamic formation of hetero-core complexes that include both mono- and di-lipoyl forms of AtmtE2.

Results from two nationwide surveys conducted in 2008 and 2009 were used for the analysis. Findings confirmed a decline in demand for red oak and an increase in species diversity in the market, although a majority of sales were dominated by five species. Results also showed an increasing importance of markets for lower grades of lumber, such as pallets, containers, and railroad ties, and a decline in demand for higher-value products such as furniture and kitchen cabinets. The importance of the lumber distributor role in the hardwood supply chain also has increased. Both sawmills and suppliers have increased their offerings of customized products and services in response to market demand. The customer base is changing, with smaller, more customized orders being sold to smaller businesses. Some of the trends and changes identified are structural and long-running in nature and are not expected to change in the short term.

TI Changes in the International Trade Balance of US Hardwood Products from 1990 to 2013 SO BIORESOURCES LA English DT Article DE US hardwood exports; US hardwood imports; International trade; Hardwood products AB We examine U.S. exports and imports of hardwood products from 1990 to 2013. These products include logs, lumber, veneer, chips, molding, cooperage, plywood, and flooring. The values of hardwood products exported and imported have fluctuated over the years but have generally increased. More substantial changes have occurred with the countries and regions receiving U.S. exports, as well as with those importing into the United States. The primary region receiving U.S. hardwood log and lumber in 1990 was Western Europe, but today, China is the most important market. East Asia has been the most important source region for U.S. hardwood plywood imports, but the specific sources have shifted from Indonesia and Taiwan in 1990 to China today. The overall balance of U.S. hardwood product trade has remained positive for most of the years examined, with the United States having a comparative advantage in exporting logs and lumber. In contrast, the United States has a comparative disadvantage in hardwood plywood exports. C1 [Luppold, William G.] US Forest Serv, No Res Stn, Princeton, WV 24740 USA.

Growing one or more generations in a common environment can help minimize maternal effects, but is often not practical with long-lived species. In Pinus aristata Engelm. and Pinus flexilis James, we assessed maternal effects by growing offspring sourced over multiple years from the same mother trees, comparing growth traits between source years. Additionally, we explored the effect of maternal environment on seed characteristics by collecting five twig clippings from each mother tree and measuring characteristics indicative of the relative vigor of the tree during each seed source year. The effect of year was significant for twig growth characteristics, seed size, and seedling performance. For both species, there were significant relationships between the relative inter-annual (RIA) variation in seed mass and the RIA variation in numerous seedling traits including cotyledon length, seedling total dry mass, and needle length. Variation in seed mass was not predicted by yearly variation in the maternal plant's phenotypic traits. These results support the hypothesis that maternal effects translate into variation in early seedling growth and suggest possibilities to statistically account for them in common garden studies involving long-lived species.

The objective of this study was to investigate the role of intraocular leptospiral infections in horses with ERU in the Southern United States. Blood and ocular fluid samples were collected from horses with ERU and normal controls. Leptospira serology was performed using microscopic agglutination test (MAT). Aqueous and vitreous humor samples were obtained and submitted for aerobic and Leptospira culture, polymerase chain reaction (PCR), and MAT. Twenty-one control horses (40 eyes) and 31 ERU horses (46 eyes) were available. Serology was available for 48 of 52 horses: 16 of 21 control and 23 of 27 affected horses were positive for at least one serovar; bratislava was the most common serovar identified. Bacillus sp. and Micrococcus sp. were cultured from one control horse's eye; Streptococcus sp. (n = 1) and Leptospira (n = 6) were cultured from the eyes of six ERU horses. Leptospira isolates belonged to serogroup pomona (n = 4) and grippotyphosa (n = 2). Polymerase chain reaction results were positive in 14 of 31 (45%) horses with ERU; no control horses were positive by PCR (P = .0001). Microscopic agglutination test was positive for 17 of 24 ERU horses (71%) and one 21(4.7%) normal horses (P < .0001). Horses with ERU had a high prevalence of Leptospira infection based on PCR and MAT results from intraocular fluids compared with control horses. The diagnosis of intraocular infections was not aided by serology and required specific invasive sampling of ocular fluid. Leptospira infection should be considered as a cause of ERU in the Southern United States. (C) 2014 Elsevier Inc. All rights reserved.

The flux and composition of dissolved organic matter (DOM) from soils to rivers are sensitive to permafrost configuration and its impact on subsurface hydrology and groundwater discharge. Here, we evaluate the utility of DOM composition and age as a tool for detecting permafrost thaw in three rivers (Beaver, Birch, and Hess Creeks) within the discontinuous permafrost zone of interior Alaska. We observed strong temporal controls on C-14 content of hydrophobic acid isolates (C-14-HPOA) across all rivers, with the most enriched values occurring during spring snowmelt (758) and most depleted during winter flow (-218). Radiocarbon ages of winter flow samples ranged from 35 to 445yr BP, closely tracking estimated median base flow travel times for this region (335years). During spring snowmelt, young DOM was composed of highly aromatic, high molecular-weight compounds, whereas older DOM of winter flow had lower aromaticity and molecular weight. We observed a significant correlation between C-14-HPOA and UV absorbance coefficient at 254nm ((254)) across all study rivers. Using (254) as an optical indicator for C-14-HPOA, we also observed a long-term decline in (254) during maximum annual thaw depth over the last decade at the Hess Creek study site. These findings suggest a shift in watershed hydrology associated with increasing active layer thickness. Further development of DOM optical indicators may serve as a novel and inexpensive tool for detecting permafrost degradation in northern watersheds.

TI Evaluating the long-term management of introduced ungulates to protect the palila, an endangered bird, and its critical habitat in subalpine forest of Mauna Kea, Hawai'i SO ARCTIC ANTARCTIC AND ALPINE RESEARCH LA English DT Article ID FERAL HERBIVORES; ELEVATION; MAMANE; ECOSYSTEMS; RECOVERY; IMPACT; LEPIDOPTERA; TORTRICIDAE; PARASITISM; EXCLUSION AB Under the multiple-use paradigm, conflicts may arise when protection of an endangered species must compete with other management objectives. To resolve such a conflict in the Critical Habitat of the endangered Hawaiian honeycreeper, palila (Loxioides bailleui), federal courts ordered the eradication of introduced ungulates responsible for damaging the mamane (Sophora chrysophylla) forest on which palila depend. During 1980-2011, a total of 18,130 sheep (Ovis aries and O. gmelini musimon) and 310 goats (Capra hircus) were removed from Palila Critical Habitat (PCH) primarily by public hunters (54%) and secondarily by aerial shooting. Nevertheless, our analysis indicates that ungulates have increased over time. Palila numbers have declined sharply since 2003 due to long-term habitat degradation by ungulates and drought. Although culling ungulate populations has allowed some habitat improvement, their complete removal is necessary for palila to recover, especially given the potential for continued drought. Introduced predators are being controlled to reduce palila mortality, mamane and other native trees are being planted to restore some areas, and fencing is being constructed to prevent ungulate immigration. Funds are recently available for more effective eradication efforts, which are urgently needed to eliminate browsing damage in PCH and protect the palila from extinction.

We evaluated the use of satellite imagery as a quantitative measure of the relationship between the spectral diversity of satellite imagery, habitat heterogeneity, and plant species richness. A 16 km(2) portion of a military training area in Germany was systematically sampled by plant taxonomic experts on a grid of one hundred 1-ha plots. The diversity of disturbance types, resulting habitat heterogeneity, and plant species richness were determined for each plot. Using an IKONOS multispectral satellite image, we examined 168 metrics of spectral diversity as potential indicators of those independent variables. Across all potential relationships, a simple count of values per spectral band per plot, after compressing the data from the original 11-bit format with 2048 potential values per band into a maximum of 100 values per band, resulted in the most consistent predictor for various metrics of habitat heterogeneity and plant species richness. The count of values in the green band generally out-performed the other bands. The relationship between spectral diversity and plant species richness was stronger than for measures of habitat heterogeneity. Based on the results, we conclude that remotely sensed assessment of spectral diversity, when coupled with limited ground-truthing, can provide reasonable estimates of habitat heterogeneity and plant species richness across broad areas.

A variety of physiological, behavioral and environmental factors can influence segregation of sexes and sex ratios, many of which originate with density-dependent processes. Departure from 50:50 sex ratios of double-crested cormorants (Phalacrocorax auritus) collected during control efforts in breeding and wintering areas across their eastern range of the USA were evaluated using using a Z-test as well as Stouffer's weighted Z-tests. In addition, a specifically-designed randomization test was used to evaluate density-dependent effects on primary sex ratios in cormorants from egg collections and colony nest count data over a 21-year period. Cormorants collected from breeding colonies were strongly male-biased, whereas cormorants collected from feeding flocks were slightly biased toward females. Cormorants were partly segregated by sex on the wintering grounds, with significantly more males found in areas with intensive channel catfish aquaculture. The null hypothesis that females produced a balanced sex ratio independent of number of nesting cormorants was rejected: more male embryos were produced during rapid population growth, whereas at maximum nesting number more female embryos were produced. Once populations stabilized, the sex ratio was more equal. This examination of sex ratios indicates that different management methods and locations result in sex-biased culling of cormorants. Sex-biased culling in cormorants could make population reduction efforts more efficient and reduce overall take. We suggest further research to examine density-dependent effects on primary sex ratios documented here.

TI Invasive black spiny-tailed iguanas (Ctenosaura similis) on Gasparilla Island, Florida, USA SO INTEGRATIVE ZOOLOGY LA English DT Article DE Ctenosaura similis; Florida; invasive reptile; population control; spiny-tailed iguana ID SOUTH FLORIDA; LIZARDS AB The native range of Ctenosaura similis extends from southern Mexico through Panama. From an initial introduction of 3 animals in 1979, the species now numbers in the thousands on Gasparilla Island in southwest Florida. In response to complaints of property damage from residents and threats to native species, local officials and the US Department of Agriculture Wildlife Services began a removal program in 2008. Through 2011, trappers removed 9467 ctenosaurs. The number removed declined from 32 iguanas/day in 2008 to 1.9 iguanas/day in 2011 despite no easing of the control effort. We necropsied 2757 ctenosaurs to document aspects of their natural history. Females outnumbered males overall, although the largest size class (>300 mm snout-vent length) included 32 males and just 2 females. Reproduction was seasonal. We found oviducal eggs in females from early Apr to early Jun, approximately 2 months later than C. similis in its native range. We trapped hatchlings from late Jul to early Oct coincident with the summer rainy season. Clutch size increased with female body size, with 62 being the largest clutch size recorded. In general, the biology of the invasive population on Gasparilla Island resembles native C. similis populations in Central America, except for the lack of large individuals. We suggest that shorter day length and colder temperatures create environmental conditions that are suboptimal for individual growth compared to those in the native range.

The effects of proteolysis were studied in four different brands of Mexican Queso Chihuahua made from raw milk. All of the cheeses were analyzed for chemical and sensory characteristics. Sensory testing revealed that the fresh cheeses elicited flavors of young, basic cheeses, with slight bitter notes. Analysis by gel electrophoresis and reverse phase-high performance liquid chromatography (RP-HPLC) revealed that the Queseria Blumen (X) and Queseria Super Fino (Z) cheeses show little protein degradation over time while the Queseria America (W) and Queseria Lago Grande (Y) samples are degraded extensively when aged at 4 degrees C for 8 weeks. Analysis of the mixture of water-soluble cheese proteins by mass spectrometry revealed the presence of short, hydrophobic peptides in quantities correlating with bitterness. All cheese samples contained enterococcal strains known to produce enterocins. The Wand Y cheese samples had the highest number of bacteria and exhibited greater protein degradation than that observed for the X and Z cheeses.

The evidence unveils an intriguing dual-layered mechanism of regulation whereby both the level of promoter binding-site occupancy and in situ modulation of bound transcription-factor intrinsic activity combine to generate a complex matrix of shared, but quantitatively differential, gene expression patterns, under the collective control of these PIFs across the network.A subfamily of four Phytochrome (phy)-Interacting bHLH transcription Factors (PIFs) collectively promote skotomorphogenic development in dark-grown seedlings. This activity is reversed upon exposure to light, by photoactivated phy molecules that induce degradation of the PIFs, thereby triggering the transcriptional changes that drive a transition to photomorphogenesis. The PIFs function both redundantly and partially differentially at the morphogenic level in this process. To identify the direct targets of PIF transcriptional regulation genome-wide, we analyzed the DNA-binding sites for all four PIFs by ChIP-seq analysis, and defined the genes transcriptionally regulated by each PIF, using RNA-seq analysis of pif mutants. Despite the absence of detectable differences in DNA-binding-motif recognition between the PIFs, the data show a spectrum of regulatory patterns, ranging from single PIF dominance to equal contributions by all four. Similarly, a broad array of promoter architectures was found, ranging from single PIF-binding sites, containing single sequence motifs, through multiple PIF-binding sites, each containing one or more motifs, with each site occupied preferentially by one to multiple PIFs. Quantitative analysis of the promoter occupancy and expression level induced by each PIF revealed an intriguing pattern. Although there is no robust correlation broadly across the target-gene population, examination of individual genes that are shared targets of multiple PIFs shows a gradation in correlation from strongly positive, through uncorrelated, to negative. This finding suggests a dual-layered mechanism of transcriptional regulation, comprising both a continuum of binding-site occupancy by each PIF and a superimposed layer of local regulation that acts differentially on each PIF, to modulate its intrinsic transcriptional activation capacity at each site, in a quantitative pattern that varies between the individual PIFs from gene to gene. These findings provide a framework for probing the mechanisms by which transcription factors with overlapping direct-target genes integrate and selectively transduce signals to their target networks.

TI Development of a Portable 3CCD Camera System for Multispectral Imaging of Biological Samples SO SENSORS LA English DT Article DE multispectral imaging; portable 3CCD Camera; beam splitter; prisms; parallel processing; apple defect detection ID APPLES; DEFECTS; VISION; COLOR AB Recent studies have suggested the need for imaging devices capable of multispectral imaging beyond the visible region, to allow for quality and safety evaluations of agricultural commodities. Conventional multispectral imaging devices lack flexibility in spectral waveband selectivity for such applications. In this paper, a recently developed portable 3CCD camera with significant improvements over existing imaging devices is presented. A beam-splitter prism assembly for 3CCD was designed to accommodate three interference filters that can be easily changed for application-specific multispectral waveband selection in the 400 to 1000 nm region. We also designed and integrated electronic components on printed circuit boards with firmware programming, enabling parallel processing, synchronization, and independent control of the three CCD sensors, to ensure the transfer of data without significant delay or data loss due to buffering. The system can stream 30 frames (3-waveband images in each frame) per second. The potential utility of the 3CCD camera system was demonstrated in the laboratory for detecting defect spots on apples.

The fluorescence excitation and emission matrix was used to measure for defects, sound surface and stem areas to determine the optimal fluorescence excitation and emission wavelengths for discrimination. Two-way ANOVA revealed the optimal excitation wavelength for detecting defect areas was 410 nm. Principal component analysis (PCA) was applied to the fluorescence emission spectra of all regions at 410 nm excitation to determine the emission wavelengths for defect detection. The major emission wavelengths were 688 nm and 506 nm for the detection. Fluorescence images combined with the determined emission wavebands demonstrated the feasibility of detecting defective cherry tomatoes with >98% accuracy. Multi-spectral fluorescence imaging has potential utility in non-destructive quality sorting of cherry tomatoes.

In addition to causing malformations, several plants can also cause embryonic death. These losses decrease the reproductive efficiency of animals exposed to these plants. The aim of this study was to determine if teratogenic plants such as lupines or tobaccos cause embryonic losses. A goat model using the plant Nicotiana glauca was used in this study, as this model has been used to characterize the mechanism of Lupinus, Conium, and Nicotiana-induced terata. Four groups of goats were dosed from gestational day 1-10, 11-20, 21-30, and 31-40. Goats were evaluated via ultrasound imaging for pregnancy after completion of the dosing regimen and kids were evaluated for malformations at the time of parturition. Overall, there was no evidence from this study that N. glauca (anabasine) at this dose (2 g/kg/day) would cause embryonic losses in goats. However, the dose of N. glauca used in this study was at the lower threshold that would be expected to produce terata. Therefore it is possible that higher doses of anabasine could cause embryonic loss. Further work is also needed to characterize the kinetic profile of anabasine, and other teratogenic alkaloids, in the fetal compartments. Published by Elsevier Ltd. C1 [Welch, K. D.; Lee, S.

Methodologically, there is also debate about whether beverages should be included in dietary ED calculations. To address these issues, studies examining the effects of ED on El or body weight in nonelderly adults were reviewed. Different approaches to calculating dietary ED do not appear to alter the direction of reported relations between ED and body weight. Evidence that lowering dietary ED reduces El in short-term studies is convincing, but there are currently insufficient data to determine long-term effectiveness for weight loss. The review also identified key barriers to progress in understanding the role of ED in energy regulation, in particular the absence of a standard definition of ED, and the lack of data from multiple long-term clinical trials examining the effectiveness of low-ED diet recommendations for preventing both primary weight gain and weight regain in nonobese individuals. Long-term clinical trials designed to examine the impact of dietary ED on energy regulation, and including multiple ED calculation methods within the same study, are still needed to determine the importance of ED in the regulation of EI and body weight.

The updated results are consistent with the 2005 BTS in terms of overall magnitude. The 2005 BTS projected between 860 and 1240 Tg of biomass available in the 2050 timeframe, while the Billion-Ton Update (BT2), for a price of 66 $ Mg-1, projected between 994 and 1483 Tg in 2030. For the BT2, forest residue biomass potential was determined to be less owing to tighter restrictions on forest residue supply including restrictions due to limited projected increase in traditional harvest for pulpwood and sawlogs. Crop residue potential was also determined to be less because of the consideration of soil carbon and not allowing residue removal from conventionally tilled corn acres. Energy crop potential was estimated to be much greater largely because of land availability and modeling of competition among various competing uses of the land. Generally, the scenario assumptions in the updated assessment are much more plausible to show a "billionton" resource, which would be sufficient to displace 30% or more of the country's present petroleum consumption and provide more than enough biomass to meet the 2022 requirements of the Renewable Fuel Standard.
