The link between nitrogen cycling and soil microbial community composition in forest soils of western Oregon

Creator:: Boyle, Stephanie A.
Abstract:: The objectives of this thesis were to examine the links between soil microbial community composition and function using the nitrogen (N) cycle as a model for these interactions and to assess the impact of environmental factors such as microclimate, vegetation type, and nutrient availability on microbial diversity and N transformations...

Bumble Bee (Hymenoptera: Apidae) Foraging Distance and Colony Density Associated With a Late-Season Mass Flowering Crop

Creator:: Rao, Sujaya and Strange, James P.
Abstract:: Foraging behaviors of bumble bee workers have been examined in natural habitats, whereas agricultural landscapes, which can provide insights on flight distances to fragmented patches of bloom, have received limited attention. In particular, information on worker flight distances to crops blooming several months after nests have been established is invaluable....

Carbon cycling and priming of soil organic matter decomposition in a forest soil following glucose additions

Creator:: Diaz, David D.
Abstract:: Soils are a globally significant carbon (C) pool and have the potential to respond to elevated CO2 and environmental changes through positive feedback cycles that enhance the turnover of soil organic matter (SOM). Understanding the mechanisms governing the turnover of SOM is particularly important for modeling the fate of C...

FR‐H3 : a new QTL to assist in the development of fall-sown barley with superior low temperature tolerance

Creator:: Fisk, Scott P.
Abstract:: Fall-sown barley will be increasingly important in the era of climate change due to higher yield potential and efficient use of water resources. Resistance/tolerance to biotic and abiotic stresses will be critical. Low temperature is an abiotic stress of great importance. Resistance to barley stripe rust (incited by Puccinia striifomis...

The Hordeum Toolbox: The Barley Coordinated Agricultural Project Genotype and Phenotype Resource

Creator:: Blake, Victoria C., Kling, Jennifer G., Hayes, Patrick M., Jannink, Jean-Luc, Jillella, Suman R., Lee, John, Matthews, David E., Chao, Shiaoman, Close, Timothy J., Muehlbauer, Gary J., Smith, Kevin P., Wise, Roger P., and Dickerson, Julie A.
Abstract:: The use of DNA markers in public sector plant breeding is now the norm. Such markers are common across breeding programs and this commonality enables and enhances collaboration. Therefore, large collaborative research projects that measure several phenotypes across multiple environments coupled with the expanding amount of genotype data attainable with...

Identifying QTLs for Sustainability Traits (Disease Resistance and Malt Quality) in the Facultative/Winter 6-rowed Elite Malting Barley GWAS Panel, the TCAP FAC-WIN6

Creator:: Belcher, Araby Ruth
Abstract:: This dissertation consists of a general introduction, three research manuscripts, and general conclusions regarding the mapping of quantitative trait loci (QTLs) for sustainability traits in the Triticeae Coordinated Agricultural Project (TCAP) facultative/winter 6-rowed elite malting barley genome-wide association studies (GWAS) mapping panel, the TCAP FAC-WIN6. The first research manuscript, a...

The genetics of winterhardiness in barley : perspectives from genome-wide association mapping

Creator:: von Zitzewitz, Jarislav
Abstract:: Fall-planted barley makes the best use of available precipitation in the Pacific Northwest of the United States. This growth habit is also suitable to many other areas of the world. A prerequisite for production in most of these areas is tolerance of low temperature during the vegetative growth stages. Fall-planted...

From the Oregon Wolfe Barley to fall-sown food barley : markers, maps, marker-assisted selection and quantitative trait loci

Creator:: Chutimanitsakun, Yada
Abstract:: Understanding complex traits is a fundamental challenge in plant genetics and a prerequisite for molecular breeding. Tools for trait dissection are markers, maps, and quantitative trait locus (QTL) analysis. Marker-assisted selection (MAS) is an application that integrates these tools. In this thesis research, a new sequence-based marker was evaluated, maps...

Quantitative Trait Loci Associated with the Tocochromanol (Vitamin E) Pathway in Barley

Creator:: Graebner, Ryan C., Wise, Mitchell, Cuesta-Marcos, Alfonso, Geniza, Matthew, Blake, Tom, Blake, Victoria C., Butler, Joshua, Chao, Shiaoman, Hole, David J., Horsley, Rich, Jaiswal, Pankaj, Obert, Don, Smith, Kevin P., Ullrich, Steven, and Hayes, Patrick M.
Abstract:: The Genome-Wide Association Studies approach was used to detect Quantitative Trait Loci associated with tocochromanol concentrations using a panel of 1,466 barley accessions. All major tocochromanol types- α-, β-, δ-, γ-tocopherol and tocotrienol- were assayed. We found 13 single nucleotide polymorphisms associated with the concentration of one or more of...

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...
