| changes in cadmium mobility during composting and after soil application. | the effect of twelve weeks of composting on the mobility and bioavailability of cadmium in six composts containing sewage sludge, wood chips and grass was studied, along with the cadmium immobilization capacity of compost. two different soils were used and cd accumulation measured in above-ground oat biomass (avena sativa l.). increasing ph appears to be an important cause of the observed decreases in available cadmium through the composting process. a pot experiment was performed with two diffe ... | 2009 | 19398321 |
| viscosity dependence of primary photoprocesses of 124 kilodalton phytochrome. | to characterize the nature of primary photoprocesses of phytochrome which serves as the red-far red reversible photoreceptor for photomorphogenesis in plants, viscosity dependence of the fluorescence lifetimes of phytochrome isolated from etiolated oat seedling (avena sativa l.) has been investigated. the fluorescence decay of phytochrome exhibited approximately two components, one with lifetime in the range of 50-70 ps and another with 1.1-1.2 ns in phosphate buffer with or without 40-67% glyce ... | 1986 | 19431669 |
| evidence for variation in the optimal translation initiation complex: plant eif4b, eif4f, and eif(iso)4f differentially promote translation of mrnas. | eukaryotic initiation factor (eif) 4b is known to interact with multiple initiation factors, mrna, rrna, and poly(a) binding protein (pabp). to gain a better understanding of the function of eif4b, the two isoforms from arabidopsis (arabidopsis thaliana) were expressed and analyzed using biophysical and biochemical methods. plant eif4b was found by ultracentrifugation and light scattering analysis to most likely be a monomer with an extended structure. an extended structure would facilitate the ... | 2009 | 19493973 |
| in vitro fermentation of oat flours from typical and high beta-glucan oat lines. | two publicly available oat (avena sativa) lines, "jim" and "paul" (5.17 and 5.31% beta-glucan, respectively), and one experimental oat line "n979" (7.70% beta-glucan), were used to study the effect of beta-glucan levels in oat flours during simulated in vitro digestion and fermentation with human fecal flora obtained from different individuals. the oat flours were digested by using human digestion enzymes and fermented by batch fermentation under anaerobic conditions for 24 h. the fermentation p ... | 2009 | 19572543 |
| primary reactions of the lov2 domain of phototropin studied with ultrafast mid-infrared spectroscopy and quantum chemistry. | phototropins, major blue-light receptors in plants, are sensitive to blue light through a pair of flavin mononucleotide (fmn)-binding light oxygen and voltage (lov) domains, lov1 and lov2. lov2 undergoes a photocycle involving light-driven covalent adduct formation between a conserved cysteine and the fmn c(4a) atom. here, the primary reactions of avena sativa phototropin 1 lov2 (aslov2) were studied using ultrafast mid-infrared spectroscopy and quantum chemistry. the singlet excited state (s1) ... | 2009 | 19580760 |
| conformational heterogeneity and propagation of structural changes in the lov2/jalpha domain from avena sativa phototropin 1 as recorded by temperature-dependent ftir spectroscopy. | phototropins control phototropism, chloroplast movement, stomatal opening, and leaf expansion in plants. phototropin 1 (phot1) is composed of a kinase domain linked to two blue light-sensing domains, lov2 and lov1, which bind flavin mononucleotide. disruption of the interaction between the lov2 domain and a helical segment named jalpha, joining lov to the kinase domain, induces the subsequent kinase activity of phototropin 1 and further-downstream signal transduction. here we study the effects o ... | 2009 | 19580761 |
| [effects of enhanced solar uv-b radiation on the effective photosynthetic leaf area and milking phase of oat under natural field condition in qing tibetan plateau]. | stratospheric ozone depletion occurs mainly over polar regions during the spring when the solar ultraviolet b-band (280-315 nm, uv-b) radiation is most intense in a year, but over the qing tibetan plateau region, the intensity is highest from june to september when the amount of uv-b radiation reaching the regions is more than that in the adjacent areas lying in the same latitude by 10%. from june to september is just the time of plant's germination, development, and reproduction in the alpine r ... | 2009 | 19650494 |
| line-scanning microscopy for time-gated and spectrally resolved fluorescence imaging. | laser-scanning fluorescence microscopy for efficient acquisition of time-gated and spectrally resolved fluorescence images was developed based on line illumination of the laser beam and detection of the fluorescence image through a slit. in this optical arrangement, the fluorescence image was obtained by scanning only one axis perpendicular to the excitation line, and the acquisition time was significantly reduced compared with conventional laser-scanning confocal microscopy. a multidimensional ... | 2008 | 19669492 |
| nitrogen fertilizer effects on soil carbon balances in midwestern u.s. agricultural systems. | a single ecosystem dominates the midwestern united states, occupying 26 million hectares in five states alone: the corn-soybean agroecosystem [zea mays l.-glycine max (l.) merr.]. nitrogen (n) fertilization could influence the soil carbon (c) balance in this system because the corn phase is fertilized in 97-100% of farms, at an average rate of 135 kg n x ha(-1) x yr(-1). we evaluated the impacts on two major processes that determine the soil c balance, the rates of organic-carbon (oc) inputs and ... | 2009 | 19688919 |
| addition of individual chromosomes of maize inbreds b73 and mo17 to oat cultivars starter and sun ii: maize chromosome retention, transmission, and plant phenotype. | oat-maize addition (oma) lines with one, or occasionally more, chromosomes of maize (zea mays l., 2n = 2x = 20) added to an oat (avena sativa l., 2n = 6x = 42) genomic background can be produced via embryo rescue from sexual crosses of oat x maize. self-fertile disomic addition lines of different oat genotypes, mainly cultivar starter, as recipient for maize chromosomes 1, 2, 3, 4, 5, 6, 7, 9, and the short arm of 10 and a monosomic addition line for chromosome 8, have been reported previously i ... | 2009 | 19707741 |
| angiotensin-i converting enzyme inhibitory activity of hydrolysates from oat (avena sativa) proteins by in silico and in vitro analyses. | the potential for producing antihypertensive peptides from oat proteins through enzymatic hydrolysis was assessed in silico and confirmed in vitro. thermolysin (ec 3.4.24.27) was predicted using biopep database as the enzyme that would theoretically produce the most angiotensin i converting enzyme (ace) inhibitory peptides from oat. experimental evidence confirmed that strong ace-inhibitory activity was produced under various hydrolysis conditions. hydrolysates produced under high enzyme-to-subs ... | 2009 | 19731915 |
| fall growth, nutritive value, and estimation of total digestible nutrients for cereal-grain forages in the north-central united states. | throughout the southern great plains, wheat is managed frequently as a dual-purpose crop, but this production paradigm is not necessarily applicable throughout other regions of the united states, and a wider array of management options can be considered for forage-only uses of cereal grains. our objectives were to assess the fall-growth potential of wheat (triticum aestivum l.), triticale (x triticosecale wittmack), and oat (avena sativa l.) cultivars in wisconsin, and then to further evaluate a ... | 2010 | 19749014 |
| mapping of sts markers obtained from oat resistance gene analog sequences. | two previously isolated resistance gene analogs (rgas) of oat have been located as rflps in the reference map of avena byzantina 'kanota' x avena sativa 'ogle' in regions either homologous or homoeologous to loci for resistance to puccinia coronata, the causal agent of crown rust. in this study, the rgas were mapped in two recombinant inbred line (ril) populations that segregate for crown rust resistance: the diploid avena strigosa x avena wiestii ril population (asw), which has been used for ma ... | 2009 | 19767892 |
| [the role of hormonal balance in plant adaptation to flooding]. | the effect of flooding on the growth parameters and hormonal dynamics (auxins, abscisic acid, cytokinins, gibberellins, and ethylene) has been studied in a vegetation experiment on the leaves of wheat (triticum aestivum l.) and oat (avena sativa l.). growth inhibition during flooding in both species was due to the accumulation of abscisic acid and ethylene, while the repair processes were due to the increased level of auxins, cytokinins, and gibberellins. the difference in the hormonal response ... | 2016 | 19768962 |
| [effect of strengthening solar ultraviolet b band irradiation on oat (avena sativa l. ) yield and its components in qing tibetan plateau]. | stratospheric ozone depletion occurs mainly over polar regions during the spring when the solar ultraviolet b-band (280-315 nm, uv-b) radiation is most intense in a year, but over the qing tibetan plateau region, the highest intensity is from june to september when the amount of uv-b radiation reaching the regions is more than that in the adjacent areas lying in the same latitude by 10%. from june to september is just the time of plant's germination, development, and reproduction in the alpine r ... | 2009 | 19839346 |
| lipid asymmetry in plant plasma membranes: phosphate deficiency-induced phospholipid replacement is restricted to the cytosolic leaflet. | as in other eukaryotes, plant plasma membranes contain sphingolipids, phospholipids, and free sterols. in addition, plant plasma membranes also contain sterol derivatives and usually <5 mol% of a galactolipid, digalactosyldiacylglycerol (dgdg). we earlier reported that compared to fully fertilized oats (avena sativa), oats cultivated without phosphate replaced up to 70 mol% of the root plasma membrane phospholipids with dgdg. here, we investigated the implications of a high dgdg content on membr ... | 2010 | 19966136 |
| phytotoxic activity of salvia x jamensis. | a study has been carried out on the surface exudate of salvia x jamensis, which showed a significant phytotoxic activity against papaver rhoeas l. and avena sativa l.. bioguided separation of the exudate yielded active fractions from which 3 beta-hydroxy-isopimaric acid (1), hautriwaic acid (2), betulinic acid (3), 7,8 beta-dihydrosalviacoccin (4), isopimaric acid (5), 14 alpha-hydroxy-isopimaric acid (7), 15,16-epoxy-7 alpha, 10 beta-dihydroxy-clerod-3,13(16),14-trien-17,12;18,19-diolide (8), c ... | 2009 | 20120094 |
| the chromosome content and genotype of two wheat cell lines and of their somatic fusion product with oat. | somatic hybridization seeks to genetically combine phylogenetically distant parents. an effective system has been established in bread wheat (triticum aestivum l.) involving protoplasts from a non-totipotent cell line adapted to in vitro culture (t(1)) in combination with totipotent protoplasts harvested from embryogenic calli (t(2)). here, we report the karyotype and genotype of t(1) and t(2). line t(1) carries nine a (a-genome of wheat), seven b (b-genome of wheat) and eight d (d-genome of whe ... | 2010 | 20204401 |
| quantitative trait loci in the ogle/tam o-301 oat mapping population controlling resistance to puccinia coronata in the field. | crown rust is the most damaging disease of cultivated oat (avena sativa) and genetic resistance is the primary means of controlling the disease. quantitative trait loci (qtl) with major and minor effects have been identified in ogle1040 and tam o-301 (most notably, pc58 and pcnqmg/lgcg from tam o-301 and ot-27 from ogle1040) through single-isolate greenhouse and field tests. to map loci and determine the effectiveness of previously identified qtl against naturally occurring pathogen populations ... | 2010 | 20373970 |
| development and characterization of an oat tilling-population and identification of mutations in lignin and beta-glucan biosynthesis genes. | oat, avena sativa is the sixth most important cereal in the world. presently oat is mostly used as feed for animals. however, oat also has special properties that make it beneficial for human consumption and has seen a growing importance as a food crop in recent decades. increased demand for novel oat products has also put pressure on oat breeders to produce new oat varieties with specific properties such as increased or improved beta-glucan-, antioxidant- and omega-3 fatty acid levels, as well ... | 2010 | 20459868 |
| variability in xylanase and xylanase inhibition activities in different cereals in the healthgrain diversity screen and contribution of environment and genotype to this variability in common wheat. | endo-1,4-beta-d-xylanases (ec 3.2.1.8, xylanases) and xylanase inhibitors, that is, taxi (triticum aestivum xylanase inhibitor), xip (xylanase inhibiting protein), and tlxi (thaumatin-like xylanase inhibitor) type xylanase inhibitors, which naturally occur in cereals, are believed to be at the basis of a significant part of the variability in biotechnological functional properties of cereals. xylanase inhibitors in particular affect grain functionality during processing and in animal feeds when ... | 2010 | 20462210 |
| mobilization of lipid reserves during germination of oat (avena sativa l.), a cereal rich in endosperm oil. | since the cereal endosperm is a dead tissue in the mature grain, beta-oxidation is not possible there. this raises the question about the use of the endosperm oil in cereal grains during germination. in this study, mobilization of lipids in different tissues of germinating oat grains was analysed using thin-layer and gas chromatography. the data imply that the oat endosperm oil [triacylglycerol (tag)] is not a dead-end product as it was absorbed by the scutellum, either as free fatty acids (ffas ... | 2010 | 20497973 |
| hindered rotation of a cofactor methyl group as a probe for protein-cofactor interaction. | exploring protein-cofactor interactions on a molecular level is one of the major challenges in modern biophysics. based on structural data alone it is rarely possible to identify how subtle interactions between a protein and its cofactor modulate the protein's reactivity. in the case of enzymatic processes in which paramagnetic molecules play a certain role, epr and related methods such as endor are suitable techniques to unravel such important details. in this contribution, we describe how cryo ... | 2010 | 20536240 |
| effects of native grass cover crops on beneficial and pest invertebrates in australian vineyards. | indigenous cover crops have the potential to promote an increase in natural enemies providing fortuitous control of pest species and other ecosystem services. we test this idea in a vineyard in south eastern australia, where reduced water availability because of drought coupled with increased temperatures has generated interest in sustainable alternatives to the exotic perennial cover crops commonly planted. three endemic perennial cover crops, comprising the grasses austrodanthonia richardsonii ... | 2010 | 20550812 |
| oats (avena sativa) reduce atherogenesis in ldl-receptor-deficient mice. | the cholesterol-lowering properties of oats, largely ascribed to its contents of soluble fibers, beta-glucans, are well established, whereas effects on atherogenesis are less well elucidated. oats also contains components with reported antioxidant and anti-inflammatory effects that may affect atherogenesis. in this work we examined effects of oat bran on plasma cholesterol, markers of inflammation, enos expression and development of atherosclerosis in ldl-receptor-deficient (ldlr(-/-)) mice. | 2010 | 20553794 |
| development of oat-based markers from barley and wheat microsatellites. | although microsatellites are an efficient and reliable genetic marker system, availability is limited in cultivated oat (avena sativa l.). previous research has suggested that microsatellites from related species may be adapted to oat. this study investigated the stability of existing oat microsatellites, sequenced polymorphic oat amplicons derived from wheat (triticum aestivum l.) and barley (hordeum vulgare l.) primers, and redesigned primers to develop oat-based markers. we evaluated 161 publ ... | 2010 | 20555435 |
| qtls for important breeding characteristics in the doubled haploid oat progeny. | a homozygous mapping population, consisting of doubled haploid (dh) oat (avena sativa l.) plants generated through anther culture of f1 plants from the cross between the finnish cultivar 'aslak' and the swedish cultivar 'matilda', was used to construct an oat linkage map. ten agronomic and quality traits were analyzed in the dh plants from field trials in 2005 and 2006. leaf blotch (caused by pyrenophora avenae) resistance was also evaluated in a greenhouse test with 2 different isolates. one to ... | 2010 | 20555437 |
| rationally improving lov domain-based photoswitches. | genetically encoded protein photosensors are promising tools for engineering optical control of cellular behavior; we are only beginning to understand how to couple these light detectors to effectors of choice. here we report a method that increases the dynamic range of an artificial photoswitch based on the lov2 domain of avena sativa phototropin 1 (aslov2). this approach can potentially be used to improve many aslov2-based photoswitches. | 2010 | 20562867 |
| antioxidant activities of aged oat vinegar in vitro and in mouse serum and liver. | the present study focused on the antioxidant activities of aged oat (avena sativa l.) vinegar. the antioxidant activities of oat and vinegar have been proved by many previous research studies. it should be noted that oat vinegar, as a novel seasoning, has antioxidant activity. | 2010 | 20564418 |
| use of earthworms (eisenia fetida) to reduce phytotoxicity and promote humification of pre-composted olive oil mill wastewater. | olive mill wastewaters (omww) contain a high recalcitrant organic load and an associated toxicity that make their treatment necessary before environmental application. the aim of this study was to evaluate the feasibility of promoting the valorization and reducing the phytotoxicity of omww through a pre-composting process together with straw-chip bulking materials followed by the application of earthworms (eisenia fetida) in the presence of oat seedlings (avena sativa l.) seedlings. | 2010 | 20602513 |
| heavy metal concentrations in plants and different harvestable parts: a soil-plant equilibrium model. | a mathematical interaction model, validated by experimental results, was developed to modeling the metal uptake by plants and induced growth decrease, by knowing metal in soils. the model relates the dynamics of the uptake of metals from soil to plants. also, two types of relationships are tested: total and available metal content. the model successfully fitted the experimental data and made it possible to predict the threshold values of total mortality with a satisfactory approach. data are tak ... | 2010 | 20605666 |
| a new chromosome nomenclature system for oat (avena sativa l. and a. byzantina c. koch) based on fish analysis of monosomic lines. | fluorescent in situ hybridization (fish) with multiple probes was used to analyze mitotic and meiotic chromosome spreads of avena sativa cv 'sun ii' monosomic lines, and of a. byzantina cv 'kanota' monosomic lines from spontaneous haploids. the probes used were a. strigosa pas120a (a repetitive sequence abundant in a-genome chromatin), a. murphyi pam1 (a repetitive sequence abundant in c-genome chromatin), a. strigosa pits (internal transcribed spacer of rdna) and the wheat rdna probes pta71 (nu ... | 2010 | 20658121 |
| in situ disappearance of dry matter and fiber from fall-grown cereal-grain forages from the north-central united states. | recent research has demonstrated that fall-grown wheat (triticum aestivum l.), triticale (x triticosecale wittmack), and oat (avena sativa l.) forages contain limited lignin and exhibit relatively stable estimates of in vitro true dm disappearance, as well as tdn, across a wide fall-harvest window. these traits suggest that ruminal availability of forage fiber is extensive. our objectives were to evaluate this premise by assessing in situ dm and ndf disappearance for kaskaskia wheat, trical 2700 ... | 2010 | 20709871 |
| soluble sugar availability of aerobically germinated barley, oat and rice coleoptiles in anoxia. | physiological and metabolic responses to anoxia were compared for aerobically germinated seedlings of barley (hordeum vulgare), oat (avena sativa) and rice (oryza sativa). coleoptile growth of barley, oat and rice seedlings was suppressed by a 24 h-anoxic stress, but the growth of the rice coleoptiles was much greater than that of the barley and oat coleoptiles. atp concentration in the anoxic rice coleoptiles was greater than that in the anoxic barley and oat coleoptiles. concentrations of etha ... | 2010 | 20727618 |
| electrogenic plasma membrane h+-atpase activity using voltage sensitive dyes. | fast responding voltage sensitive dyes, rh421 and di-4-aspbs, were used to study the electrogenic properties of plant plasma membrane proton pumps on sealed plasma membrane vesicles extracted by two-phase partitioning from beta vulgaris and avena sativa cv swan root material. fluorescence spectroscopy in the presence of the dye rh421 (10.8 nm) was sufficiently sensitive to detect electrogenic activity of the extracted plant vesicles. the dye detection system could detect inhibition of electrogen ... | 2010 | 20734224 |
| differential responses of oat genotypes: oxidative stress provoked by aluminum. | the phytotoxic effects of aluminum and the mechanisms of genetically-based al tolerance have been widely investigated, as reported in many papers and reviews. however, investigations on many al-sensitive and al-resistant species demonstrate that al phytotoxicity and al-resistance mechanisms are extremely complex phenomena. the objective of the present study was to analyze the effects of aluminum on the activity of antioxidant enzymes such as catalase (cat), superoxide dismutase (sod), and ascorb ... | 2011 | 20853138 |
| bacterial stimulation of copper phytoaccumulation by bioaugmentation with rhizosphere bacteria. | copper contaminated areas pose environmental health risk to living organisms. remediation processes are thus required for both crop production and industrial activities. this study employed bioaugmentation with copper resistant bacteria to improve phytoremediation of vineyard soils and copper mining waste contaminated with high copper concentrations. oatmeal plant (avena sativa l.) was used for copper phytoextraction. three copper resistant bacterial isolates from oatmeal rhizosphere (pseudomona ... | 2010 | 20937516 |
| increased water resistance of ctmp fibers by oat (avena sativa l.) husk lignin. | the insertion of oat husk lignin onto chemithermomechanical pulp (ctmp) fibers was studied to increase fiber hydrophobicity. the pretreated pulp samples were subsequently used for preparation of handsheets for characterization. treatment of ctmp with laccase in the presence of oat husk lignin resulted in a significant increase in hydrophobicity of the handsheet surface, as indicated by dynamic contact angle analysis. water absorption time of 8 s was obtained with initial contact angle of 118°. a ... | 2010 | 20973545 |
| 210pb and 210po in finnish cereals. | a survey was carried out on the activity concentrations of (210)pb and (210)po in cereal grains produced in finland. the cereal species were wheat (triticum aestivum), rye (secale cereale), oats (avena sativa) and barley (hordeum vulgare), which account for 90% of the finnish consumption of cereal products. the survey consisted of 18 flour and 13 unprocessed cereal samples and one hulled grain sample from 22 flour mills. according to the results, the mean (210)pb/(210)po concentrations in wheat ... | 2011 | 21035236 |
| population structure and linkage disequilibrium in oat (avena sativa l.): implications for genome-wide association studies. | the level of population structure and the extent of linkage disequilibrium (ld) can have large impacts on the power, resolution, and design of genome-wide association studies (gwas) in plants. until recently, the topics of ld and population structure have not been explored in oat due to the lack of a high-throughput, high-density marker system. the objectives of this research were to survey the level of population structure and the extent of ld in oat germplasm and determine their implications f ... | 2011 | 21042793 |
| mechanism of signal transduction of the lov2-jα photosensor from avena sativa. | fusion proteins containing blue-light-activable protein domains possess great potential as molecular switches in cell signalling. this has recently been impressively demonstrated by connecting the light oxygen voltage lov2-jα-protein domain of a. sativa (aslov2-jα) with the rac1-gtpase, responsible for regulating the morphology and motility of metazoan cells. however, a target-oriented development of fusion proteins in conjunction with this photosensor is still very challenging, because a detail ... | 2010 | 21081920 |
| phytotoxic clerodane diterpenes from salvia miniata fernald (lamiaceae). | our ongoing research to identify natural growth inhibitors with diterpene and triterpene skeletons exuding from the surface of the aerial parts of salvia species led us to study salvia miniata fernald. ten clerodane diterpenoids were found, along with three known diterpenes. most of the isolated compounds from s. miniata inhibited the germination of papaver rhoeas l. and avena sativa l. in petri dish experiments. parallel results have been obtained in experiments carried out to evaluate the subs ... | 2011 | 21130478 |
| drought stress induced changes in lipid peroxidation and antioxidant system in genus avena. | seven species of genus avena viz., avena sativa, avena strigosa, avena brevis, avena vaviloviana, avena abyssinica, avena marocana and avena sterilis were used to study the impact of drought stress on lipid peroxidation and other antioxidant enzymes. maximum increase in the catalase activity was recorded in a. vaviloviana (129.97%) followed by a. sativa (122.82%) and a. brevis (83.38%) at vegetative stage; however at flowering stage the maximum increase was reported in a. sativa (25.62%) followe ... | 2010 | 21186716 |
| rhealba® oat plantlet extract: evidence of protein-free content and assessment of regulatory activity on immune inflammatory mediators. | owing to their high content of flavonoids and saponins, plantlets of avena sativa l. (poaceae) are likely to possess anti-inflammatory and immunoregulatory properties of value in the treatment of atopic dermatitis (ad). with a view to its potential use in atopic subjects at risk of developing sensitisation to dietary proteins, we prepared a plantlet extract without proteins and isolated 2 flavonoids, isoorientin-2''- o-arabinoside (1) and isovitexin-2''- o-arabinoside (2), and two saponins, aven ... | 2011 | 21240840 |
| the primary photophysics of the avena sativa phototropin 1 lov2 domain observed with time-resolved emission spectroscopy. | the phototropins are blue-light receptors that base their light-dependent action on the reversible formation of a covalent bond between a flavin mononucleotide (fmn) cofactor and a conserved cysteine in light, oxygen or voltage (lov) domains. the primary reactions of the avena sativa phototropin 1 lov2 domain were investigated by means of time-resolved and low-temperature fluorescence spectroscopy. synchroscan streak camera experiments revealed a fluorescence lifetime of 2.2 ns in lov2. a weak l ... | 2017 | 21261629 |
| model snp development for complex genomes based on hexaploid oat using high-throughput 454 sequencing technology. | genetic markers are pivotal to modern genomics research; however, discovery and genotyping of molecular markers in oat has been hindered by the size and complexity of the genome, and by a scarcity of sequence data. the purpose of this study was to generate oat expressed sequence tag (est) information, develop a bioinformatics pipeline for snp discovery, and establish a method for rapid, cost-effective, and straightforward genotyping of snp markers in complex polyploid genomes such as oat. | 2011 | 21272354 |
| effects of water-saving superabsorbent polymer on antioxidant enzyme activities and lipid peroxidation in oat (avena sativa l.) under drought stress. | drought stress significantly limits oat (avena sativa l.) growth and productivity. thus an efficient management of soil moisture and study of metabolic changes in response to drought are important for improved production of oat. the objective was to gain a better understanding of drought tolerance mechanisms and improve soil water management strategies using water-saving superabsorbent polymer (sap) at 60 kg ha(-1) under three irrigation levels (adequate, moderate and deficit) using a new type o ... | 2011 | 21302322 |
| influence of preceding crop on wireworm (coleoptera: elateridae) abundance in the coastal plain of north carolina. | three studies were conducted to determine the effect of preceding crop on wireworm (coleoptera: elateridae) abundance in the coastal plain of north carolina. in all three studies, samples of wireworm populations were taken from the soil by using oat, avena sativa l., baits. treatments were defined by the previous year's crop and were chosen to reflect common crop rotations in the region. across all three studies, eight wireworm species were recovered from the baits: conoderus amplicollis (gyllen ... | 2010 | 21309229 |
| modulating lov domain photodynamics with a residue alteration outside the chromophore binding site. | phototropins, a class of light-activated protein kinases, are essential for several blue light responses in plants and algae, including phototropism. these proteins contain two internal light, oxygen, and voltage sensitive (lov) domains, which bind flavin chromophores and undergo a reversible photochemical formation of a cysteinyl-flavin adduct as part of the light sensing process. while the photodynamic properties of such photosensory domains are dictated by interactions between the chromophore ... | 2011 | 21323358 |
