Understanding epistasis in linkage analysis : The Kap and lks2 loci in the Oregon Wolfe Barley poputlation

Creator:: McCoy, Serena B.
Abstract:: An organisms' genotype may not be reflected in its phenotype. For example, epistasis - the interaction of non-allelic genes can cause deviations from expected phenotypic ratios. The epistatic interaction between the hooded (Kap) and short-awned (lks2) loci in barley (Hordeum vulgare) precludes the localization of the Kap locus, based on...

Investigation of hop downy mildew through association mapping and observations of the oospore

Creator:: Parker, Thomas B.
Abstract:: Hop downy mildew is a devastating disease affecting hop requiring expensive fungicide applications throughout the growing season. Plant resistance is highly desirable and theorized as being decidedly quantitative with dominance and epistasis involved in resistance. An association mapping approach using a mixed-model was used to identify AFLP markers associated with...

Identifying candidate genes associated with cold adaptation in Douglas-fir using DNA microarrays

Creator:: Howe, Dana Kathryn
Abstract:: In forest trees from temperate and boreal regions, cold acclimation is an important adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...

The Effects of Ploidy Manipulation on ‘I3’ hemp

Creator:: McLeod, Adigun
Abstract:: Hemp is a dioecious, annual, flowering plant in the Cannabaceae family. It has been used for thousands of years to produce textiles, essential oils, and medicines. The overall purpose of these experiments was to propagate the cannabinoid-free cultivar, ‘I3’, and follow up by inducing polyploidy in the ‘I3’ hemp via...

Uncovering Biological Meaning From Genome-Scale Datasets: A Challenge and an Opportunity

Creator:: Wanzeck, Kelley M.
Abstract:: As DNA sequencing technologies continue to advance, resulting in increased throughput and decreased costs, both the number of researchers utilizing these technologies and the quantity of data outputted by a single sequencing experiment will, likewise, continue to increase. Currently, DNA sequence data can be generated at a much faster rate...

Advancing Naked Barley: Malting Protocol Manipulation and Embryo Retention Insights

Creator:: Vallejos, Cristiana L.
Abstract:: Naked (hull-less) barley has historically been grown for food, but interest in, and breeding efforts for, its use in malting and brewing have increased due to the potential benefits: reduced off-flavors, reduced spent grain, and higher malt extract. These benefits are offset by limiting factors such as high b-glucan and...

Annual Forages Differ in Response to Partial-Season Irrigation Deficit in Both Spring Seeded and Summer Seeded Cropping Systems

Creator:: Fan, Qianqian
Abstract:: Water scarcity during summer becomes a serious problem in the Pacific Northwest, threatening forage production provided to livestock. Annual forages show great potential in handling drought because of their flexibility in seeding date and short growing season, and can shift the production to periods of feed shortage and fill the...

Characterization of physiological resistance to white mold and search for molecular markers linked to resistance via advanced backcross QTL analysis in an interspecific cross between Phaseolus coccineus and P. vulgaris

Creator:: Haggard, Jack Erron
Abstract:: White mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, results in severe losses in the production of common bean, Phaseolus vulgaris, especially snap bean varieties. Advanced backcross QTL analysis was used to identify quantitative trait loci for resistance to white mold in an interspecific cross of P. vulgaris and P....
