Characteristics of the lentil strain of pea seedborne mosaic virus

Creator:: Goodell, Jody Jellison
Abstract:: The lentil strain of pea seedborne mosaic virus, PSbMV-L, was distinguished from the standard isolates of PSbMV by a natural inoculum reservoir in lentil seed and by separate resistance genes in Pisum and Lens. PSbMV-L was intermediate in symptom severity between the standard and New Zealand isolates of PSbMV. Seed...

Addressing the relationship between Pseudoperonospora cubensis and P. humuli using phylogenetic analyses and host specificity assays

Creator:: Mitchell, Melanie N.
Abstract:: The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...

Bioindication of air quality in forests of northern and central California using epiphytic macrolichen communities

Creator:: Jovan, Sarah
Abstract:: The unifying purpose of this dissertation was to describe, model, and map relationships between epiphvtic macrolichen communities and air quality in Ibrests of northern and central California. First, multivariate analyses were used to subdivide the large study area into three model areas with similar climate, topography, and lichen communities: the...

The imprint of coarse woody debris on soil biological and chemical properties in the western Oregon Cascades

Creator:: Spears, Julie D. H.
Abstract:: The abundance and spatial heterogeneity of coarse woody debris (CWD) on the forest floor is a prominent feature of Pacific Northwest (PNW) forest ecosystems. The effect of CWD on soil solution chemistry, nutrient cycling and availability, soil physical structure and formation of soil organic matter, however, remains unknown. Therefore, studies...

Development and Application of Tools for Genetic Analysis of Clonal Populations

Creator:: Kamvar, Zhian N.
Abstract:: Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...

Identification of Genetic Variation between Obligate Plant Pathogens Pseudoperonospora cubensis and P-humuli Using RNA Sequencing and Genotyping-By-Sequencing

Creator:: Summers, Carly F., Gulliford, Colwyn M., Carlson, Craig H., Lillis, Jacquelyn A., Carlson, Maryn O., Cadle-Davidson, Lance, Gent, David H., and Smart, Christine D.
Abstract:: RNA sequencing (RNA-seq) and genotyping-by-sequencing (GBS) were used for single nucleotide polymorphism (SNP) identification from two economically important obligate plant pathogens, Pseudoperonospora cubensis and P. humuli. Twenty isolates of P. cubensis and 19 isolates of P. humuli were genotyped using RNA-seq and GBS. Principle components analysis (PCA) of each data...

Within-population genetic structure differs between two sympatric sister-species of ectomycorrhizal fungi, Rhizopogon vinicolor and R. vesiculosus

Creator:: Dunham, Susie M., Mujic, Alija Bajro, Spatafora, Joseph W., and Kretzer, Annette M.
Abstract:: Using spatial autocorrelation analysis, we examined the within-population genetic structure of Rhizopogon vinicolor and R. vesiculosus, two hypogeous ectomycorrhizal (EM) species that are sympatric sister taxa known to differ in their clonal structure. We collected 121 sporocarps and 482 tuberculate EM of both species from a 20 ha forest stand...

Lichen response to the environment and forest structure in the western Cascades of Oregon

Creator:: Martin, Erin P.
Abstract:: Lichens are an important part of the biota in western Oregon forests, where they perform valuable ecological roles and contribute significantly to biodiversity. Lichens in western Oregon are threatened by a number of factors including air pollution and land use practices. If we wish to maintain the persistence of lichens...
