  • Diversity and Impact of Soft Rot Pathogens of Potato in the Columbia Basin

    Creator:
    Brazil, Jessie A.
    Abstract:
    Bacterial soft rot of potato (Solanum tuberosum), caused by Pectobacterium and Dickeya species, is among the most common and destructive potato diseases in the United States. These pathogens cause a variety of vascular wilts, and in potato cause a disease complex that includes tuber soft rot, blackleg, aerial stem rot,...

    Navarro, Sarah M.
    Abstract:
    Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....

  • Host and Pathogen Genetics in the Sharp Eyespot Disease of Wheat

    Creator:
    Liu, Jiang
    Abstract:
    Wheat sharp eyespot (SES), caused by the soil-borne fungus Rhizoctonia cerealis is a common stem disease of wheat globally. The disease caused a severe and extensive epidemic throughout the Willamette Valley of Oregon in 2014 and has remained one of the most important wheat diseases in this region. However, litte...

  • 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...

  • Genomics-enabled exploration of insect toxicity in the Pseudomonas fluorescens group

    Creator:
    Rangel, Lorena I.
    Abstract:
    Pseudomonas is a diverse genus of Gamma proteobacteria that are ubiquitous in the natural environment, including soil, water, plant surfaces, and animals. The Pseudomonas fluorescens group is a diverse collection of seven subgroups and more than 50 named species. This group is known for their production of a variety of...
