Changes in grain quality and grain protein composition of winter wheat cultivars under different levels of soil nitrogen and water stress

Creator:: Saint Pierre, Carolina
Abstract:: Hard white winter (HVVW) wheat cultivars must have superior protein quality and consistent processing quality to be successful in the Asian market. New cultivars and management strategies are needed to produce HVVW grain for both bread and noodle applications from diverse environments in the US Pacific Northwest (PNW). This study...

Phenotypic response and quantitative trait loci for resistance to Cephalosporium gramineum in winter wheat

Creator:: Quincke, Martin C.
Abstract:: Cephalosporium stripe (Cephalosporium gramineum) is an important disease limiting adoption of conservation tillage practices in the Pacific Northwest. The disease can cause severe loss of grain yield and quality in winter wheat (Triticum aestivum L.). Modified cultural practices can reduce disease incidence, but are not always dependable because of variation...

Association between dehydrin proteins and drought stress tolerance in seven wheat cultivars adapted to the Pacific Northwest of the USA

Creator:: Lopez, Cesar
Abstract:: The Pacific Northwest (PNW) is an important region for winter wheat production in the USA, where water deficits are often present at sowing and during grain filling. Consequently, improving the genetic adaptation of wheat cultivars to drought stress represents one of the main objectives in breeding programs. An observed biochemical...

The relationship of protein composition to end-product functionality of hard white wheat

Creator:: Gehlhar, Sarah Bronwen
Abstract:: Improving quality of hard white wheat (HW) cultivars in the Pacific Northwest is important to expand exports to Asia. Asian food processors prefer HW grain that can satisfy an array of baking needs, as well as produce superior quality noodle products. Three experimental populations were developed from single cross and...

Mapping quantitative trait loci underlying genome-wide recombination rate and mating system differences in meadowfoam

Creator:: Kishore, Venkata Krishna
Abstract:: Meadowfoam (Limnanthes alba Bentham; Order: Brassicales; Family: Limnanthaceae) is a self-compatible, predominantly allogamous, insect pollinated species. Meadowfoam oil is a source of novel unsaturated very-long-chain (VLC) seed oils (C₂₀ and C₂₂) with low concentrations of saturated fatty acids (typically less than 2%) and outstanding oxidative stability. Here we report the...

The effect of preplant nitrogen fertilization and soil temperature on biological nitrogen fixation and yield of alfalfa (Medicago sativa L.)

Creator:: Shuler, Philip E.
Abstract:: The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa...

Exploiting Hordeum vulgare subsp. spontaneum genetic resources : diversity analysis and germplasm development

Creator:: Matus, Iván Ariel
Abstract:: Wild barley (Hordeum vulgare subsp. spontaneum) could be a source of useful genes for improving cultivated barley. The useful genes present in Hordeum vulgare subsp. spontaneum may be new alleles at described loci, or these may be entirely new genes in the sense that there is limited allelic variation at...

Toward understanding the nature of the soil microsite in relation to nitrogen and carbon cycling

Creator:: Cliff, John B.
Abstract:: My research has focused on understanding N and C cycling in soils at small scales. Isotope dilution methods commonly used to estimate gross rates of soil chemical transformations assume homogeneous distribution of label. I explored the effects of diffusion limitations on isotope dilution experiments in soil aggregates using spherical diffusion-reaction...

Modeling Survival of Soilborne Phytophthora spp. and Characterizing Microbial Communities in Response to Soil Solarization and Biocontrol Amendment in Container Nursery Beds

Creator:: Funahashi, Fumiaki
Abstract:: In horticultural nurseries for container-grown plants, production and sales have been threatened by the presence of a quarantined plant pathogen, Phytophthora ramorum (causal agent of sudden oak death). Infested nursery beds are an important source of P. ramorum, which can initiate disease through movement with surface water to infect roots...
