Localization and genetic mapping of some factors influencing rachis brittleness and free-threshing habit in wheat

Creator:: Nalam, Vamsi J.
Abstract:: Domesticated forms of wheat exhibit traits that have increased their adaptation to cultivation by humans. Some of the most critical adaptive differences involve changes to morphological features that make the crop easier to harvest like ear rachis stiffness (brittle to non-brittle rachis) and the ease with which the seed is...

Studies on a transgenic approach to decrease gliadin content in wheat

Creator:: Bell, Shannon M.
Abstract:: Celiac disease, an autoimmune response triggered by the consumption of seed storage proteins of cereals, affects an estimated 1% of the human population. In the case of wheat (Triticum aestivum L.), one of the world’s most consumed cereals, alcohol-soluble proteins, the gliadins, have been identified as the allergy-eliciting agents. Previous...

Nuclear and chloroplast diversity of Pacific Northwest wheat (Triticum aestivum) breeding germplasm

Creator:: Edwards, Melanie Love
Abstract:: Wheat breeders must effectively maintain and manage existing genetic diversity in order to continue the development of superior genotypes. It is therefore fundamental that the genetic relationships and diversity within the germplasm pools be thoroughly characterized and understood. Recently, DNA-based markers have provided powerful tools for genetic diversity analysis. This...

Sensitivity of wheat genotypes to a toxic fraction produced by Cephalosporium gramineum and correlation with disease susceptibility

Creator:: Rahman, Mahfuzur
Abstract:: Cephalosporium stripe, caused by the soil-borne ascomycete Cephalosporium gramineum, is becoming an increasingly important disease of winter wheat (Triticum aestivum) in several areas of the world, especially where stubble mulch is practiced to maintain soil moisture and prevent erosion. As cultural control of the disease is infeasible and no fungicides...

Pyramiding quantitative trait loci conditioning partial resistance to Sclerotinia sclerotiorum in bush blue lake green beans (Phaseolus vulgaris)

Creator:: Barrett, Miles Andrew
Abstract:: Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic pathogen capable of causing white mold, a severe disease in common bean. White mold is of particular concern to the Oregon snap bean processing industry, where processors allow less than 3% incidence in harvested shipments. Breeding for white mold resistance in beans...

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...

Jointed goatgrass : outcrossing, competition with winter wheat, and response to timing and rate of imazamox

Creator:: Cannon, Joshua B.
Abstract:: Jointed goatgrass (Aegilops cylindrica Host.) is a serious weed problem in wheat (Triticum aestivum L.) production in the United States. Studies were conducted to determine the outcrossing rate, competitive ability, and effectiveness of certain control practices on jointed goatgrass. A field study was conducted over two years at four locations...

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...

Seed protein and chromosome number analyses of experimental wheat x jointed goatgrass (Aegilops cylindrica Host) hybrid derivatives

Creator:: Crémieux, Lis︡ele
Abstract:: The occurrence of seed-producing wheat x jointed goatgrass hybrids in infested wheat fields suggests the possibility of gene flow between the two species. This study investigates 'Madsen' wheat x jointed goatgrass F₁ and reciprocal backcross derivatives produced in experimental field plantings. Electrophoresis of the high molecular weight (HMW) glutenin seed...

Pyoluteorin as a signaling molecule regulating secondary metabolite production and transport genes in Pseudomonas fluorescens Pf-5

Creator:: Brodhagen, Marion L.
Abstract:: A major factor in the ability of Pseudomonas fluorescens Pf-5 to act as a biological control agent is its production of antibiotics, including pyoluteorin (PLT), 2,4-diacetylphloroglucinol (2,4-DAPG) and pyrrolnitrin (PRN). The data provided in this thesis demonstrate that the presence of any of these antibiotics in the extracellular milieu affects...
