Conservation genetics of Kincaid's lupine : a threatened plant of western Oregon and southwest Washington grasslands

Creator:: Severns, Paul M.
Abstract:: Kincaid's lupine (Lupinus oreganus Heller) is a federally listed threatened species native to remnant grassland of western Oregon and southwestern Washington, and is the primary larval host plant of a once thought extinct butterfly, Plebejus icarioides fenderi Macy. Past studies concerning Kincaid's lupine reproduction suggested that populations may suffer reductions...

Fungal and bacterial associations in heart rots of Abies concolor (Gord. and Glend.) Lindl. and techniques for estimating damage in southwestern Oregon

Creator:: Aho, Paul E.
Abstract:: Infection courts for microorganisms invading white fir heartwood were determined to be primarily branches and basal wounds. Of 11 hymenomycetes isolated from infected trees, only four: Echinodontiurn tinctorium, Phellinus chrysoloma, Pholiota adiposa, and Hericium abietis were of major significance in terms of frequency of infection and damage caused. Two or...

Pathogenesis and intertree transmission of Verticicladiella wageneri in Douglas-fir (Pseudotsuga menziesii)

Creator:: Hessburg, Paul F.
Abstract:: Verticicladiella wageneri Kendr. is a vascular wilt pathogen of Douglas-fir in the Pacific Northwest, The disease is characterized by black staining of colonized sapwood; crown symptoms are those typical of a wilting syndrome. Histopathological studies revealed that the pathogen is limited to the xylem but causes vascular dysfunction in both...

Pathological and ecological aspects of decline and mortality of Chamaecyparis nootkatensis in southeast Alaska

Creator:: Hennon, Paul Edward
Abstract:: Alaska-cedar (Chamaecvparis nootkatensIs (D. Don) Spach) is a valuable tree that is suffering from a serious decline and mortality of unknown cause throughout southeast Alaska. Epidemiological and pathological studies were initiated to determine if a pathogen is the primary cause of this problem. By examining old aerial photographs and by...

Phylogenetics, population genetics, molecular epidemiology, and pathogenicity of the Douglas-fir Swiss needle cast pathogen Phaeocryptopus gaeumannii

Creator:: Winton, Loretta M.
Abstract:: A hierarchical series of studies, based mainly on molecular data, was conducted to elucidate the life history of the Douglas-fir Swiss needle cast pathogen Phaeocryptopus gaeumannii at macro- and micro-evolutionary scales. This information was then utilized to design and evaluate molecular diagnostic tools for use in studies on the epidemiology...

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...

Ecological assessment after the addition of genetically engineered Klebsiella planticola SDF20 into soil

Creator:: Holmes, Michael T.
Abstract:: The objectives in this research were to assess whether Klebsiella planticola SDF20 could survive in soil and result in ecological effects to soil foodweb organisms and plant growth. Four experiments were conducted using soil microcosms. Klebsiella planticola SDF20 has been genetically engineered to produce ethanol from agricultural waste for use...

Biology of chlamydospores of Phytophthora ramorum

Creator:: Smith, Aaron Lee
Abstract:: The chlamydospore is a survival spore produced by 35 of the 75 described species of Phytophthora. Phytophthora ramorum Werres, de Cock & Man in't Veld, the causal agent of Sudden Oak Death (SOD), produces abundant chlamydospores in artificial culture and plant tissue. The chlamydospore is likely the most important survival...

Distribution and characterization of ice nucleation active strains of Pseudomonas syringae from diseased woody plants and grasses

Creator:: Baca, Steve
Abstract:: In a recent survey, it was observed that many woody plant species grown in Pacific Northwest nurseries exhibited disease symptoms typical of a bacterial infection and Pseudomonas syringae was commonly isolated from these tissues. The distribution of the ice nucleation phenotype among P. syringae strains recovered from these infected woody...
