Pyrenophora tritici-repentis : investigation of factors that contribute to pathogenicity

Creator:: Holman, Thomas W.
Abstract:: Pyrenophora tritici-repentis (Ptr) is the necrotrophic fungus responsible for tan spot of wheat (Triticum aestivum). Ptr causes disease on susceptible wheat cultivars through the production and secretion of host-selective toxins (HSTs). HSTs are compounds that are only known to be produced by fungi and considered to be primary determinants of...

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...

Biosystematics of parsley-ferns, Cryptogramma R. Br., in western North America

Creator:: Alverson, Edward R.
Abstract:: A biosystematic investigation of Cryptogramma section Cryptogramma in western North America has been directed towards resolution of two separate taxonomic questions. Results of this research support the hypothesis that a previously undescribed diploid (2n = 30 II) taxon, C. cascadensis, is present along with the common and widespread C. acrostichoides....

Distribution of Phytophthora rubi and Pratylenchus penetrans in Pacific Northwest Red Raspberry (Rubus idaeus) Fields

Creator:: Kroese, Duncan R.
Abstract:: The Pacific Northwest produces over 95% of the nation’s processed red raspberries, valued at over $65 million. Two of the major soilborne pathogens effecting the production of raspberry in this region are the oomycete Phytophthora rubi, which causes root rot in red raspberry plants, and the plant-parasitic nematode Pratylenchus penetrans,...

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...

Qualitative changes in cytoplasmic proteins in plants treated with plant growth regulating chemicals

Creator:: Norris, L. A.
Abstract:: This thesis concerns the alteration of the course of selective protein synthesis and morphogenesis in plants treated with growth regulating chemicals. Treatment of 48-hour-old "Alaska" pea seedlings (Pisum sativum L.) with 2, 4-D, IAA, NAA or picloram caused inhibition of epicotyl and primary root elongation and proliferation of massed lateral...

Comparative Genomics of a Plant-Pathogenic Fungus, Pyrenophora tritici-repentis, Reveals Transduplication and the Impact of Repeat Elements on Pathogenicity and Population Divergence

Creator:: Manning, Viola A., Pandelova, Iovanna, Dhillon, Braham, Wilhelm, Larry J., Goodwin, Stephen B., Berlin, Aaron M., Figueroa, Melania, Freitag, Michael, Hane, James K., Henrissat, Bernard, Holman, Wade H., Kodira, Chinnappa D., Martin, Joel, Oliver, Richard P., Robbertse, Barbara, Schackwitz, Wendy, Schwartz, David C., Spatafora, Joseph W., Turgeon, B. Gillian, Yandava, Chandri, Young, Sarah, Zhou, Shiguo, Zeng, Qiandong, Grigoriev, Igor V., Ma, Li-Jun, and Ciuffetti, Lynda M.
Abstract:: Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins ( HST), which are recognized by their host in a genotype-specific...
