  • Potato virus X : detection and inter-relationship with Verticillium dahliae and Colletotrichum atramentarium

    Creator:
    Goodell, Jody Jellison
    Abstract:
    Preliminary studies were run to determine the sensitivity and reliability of enzyme-linked immunosorbent assay (ELISA) for the detection of potato virus X (PVX). ELISA was found to be capable of detecting PVX in tobacco at a 1:3333 sample dilution. The reliability of ELISA for the detection of PVX in potato...

    Abstract:
    Data from mark-recapture study on cinnabar moths conducted at Cogswell Foster, OR, from 1986-05-29 through 1986-06-12. Data on captured and marked moths includes a number identifier, gender, wing wear (low, high), post-release behavior (mobile or immobile), capture/recapture locations (X/Y coordinates of study area, plot number, and categorical location relative to...

  • Enhancement of thiamin in plants by metabolic engineering

    Creator:
    Dong, Wei, Stockwell, Virginia O., and Goyer, Aymeric
    Abstract:
    Thiamin is an essential nutrient in the human diet. Severe thiamin deficiency leads to beriberi, a lethal disease which is common in developing countries. Thiamin biofortification of staple food crops is a possible strategy to alleviate thiamin deficiency-related diseases. In plants, thiamin plays a role in the response to abiotic...

  • Overexpression of thiamin biosynthesis genes increase leaf and seed thiamin content but not resistance to Xanthomonas oryzae in rice

    Creator:
    Dong, Wei, Thomas, Nicholas, Ronald, Pamela C., and Goyer, Aymeric
    Abstract:
    Thiamin diphosphate (ThDP), also known as vitamin B1, serves as an enzymatic cofactor in glucose metabolism, the Krebs cycle, and branched-chain amino acid biosynthesis in all living organisms. Unlike plants and microorganisms, humans are not able to synthesize ThDP de novo and must obtain it from their diet. Staple crops...

  • Biosystematics of a Western North American polyploid complex in the genus aster

    Creator:
    Guppy, Geraldine Anne Allen
    Abstract:
    Species relationships were investigated in a western North American polyploid complex in the genus Aster (Asteraceae). A combination of cytological, genetical, chemical, morphological and numerical approaches was employed. Fifteen presently recognized species were included in the study, and populations were sampled throughout most of the range of the group. Living...

  • Lichen Biomonitoring from Valley to Alpine in Central and Southern California

    Creator:
    Kovasi, Adrienne I.
    Abstract:
    In the mountains of central and southern California, high elevation wilderness areas lack epiphytic lichens that can be used to inform us about atmospheric deposition in multiple ways. Epiphytic lichens are capable of accumulating elements proportionally to the local atmospheric concentration, establishing them as commonly used biomonitor of key elements....

  • 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,...

  • Pathogenic variability and adaptation of Septoria tritici to different wheat cultivars

    Creator:
    Ahmed, Hafiz Uddin
    Abstract:
    Experiments were done to determine pathogenic variability and pathogenic adaptation of Septoria tritici to different wheat cultivars. Fifteen S. tritici isolates from California, Oregon, and Texas were evaluated on seedlings of two sets of geographically diverse wheat cultivars under greenhouse conditions. Significant isolate effects, cultivar effects, and isolate X cultivar...

    Creator:
    Lucas, Sunny L.
    Abstract:
    Coast redwood (Sequoia sempervirens) (D. Don) Endl. is a host for Phytophthora ramorum but it was unclear if the pathogen represents a significant disease risk to this tree species. In this study the susceptibility of coast redwood seedlings and the likelihood of sporulation on redwood were examined. Two methods were...

    Miller, Marilyn L., Tooley, Katie, Ferguson, Kathleen, Toma, Kyle, Mentzer, Jessica, and Moore, Larry W.
    Abstract:
    Crown gall can develop on grapevines wounded by freezing temperatures, mechanical damage or grafting. Pathogenic agrobacteria residing within the vascular system are able to initiate tumor growth in damaged plant cells. Sampling from 21 sites in Oregon vineyards and nurseries yielded diverse populations of pathogenic agrobacteria. Most of the pathogenic...
