Soil fungal hyphal dynamics and seasonal hypogeous sporocarp production in western Oregon Douglas-fir forests

Creator:: Hunt, Gary, 1945-
Abstract:: Total length and biomass of fungal mycelium in the soil of a young Douglas-fir stand in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. In a second study, phenology and taxonomy of hypogeous (belowground) sporocarps were studied over 32 months in a nearby, young...

Physiologic specialization of stripe rust (Puccinia striiformis West.) in the Pacific Northwest

Creator:: Beaver, Richard Gary, 1939-
Abstract:: The physiologic specialization of nine isolates of stripe rust (Puccinia striiformis West.) collected in the Pacific Northwest was determined. The separation of races was based on the differential susceptibility of the following wheat varieties: Cappelle Desprez, Chinese 166, Dippes Triumph, Druchamp, Etoile de Choisy, Flamingo, Gaines, Golden, Ibis, Leda, Michigan...

Production of pectic enzymes by Verticillium albo-atrum

Creator:: McIntyre, Gary Allen
Abstract:: The main objectives of this study were to determine the effect of certain environmental conditions on the quantity of poly-galacturonase (PG) produced by V. albo-atrum, and to partially purify and characterize the PGs produced by this fungus in culture and in infected tomato plants. V. albo-atrum produced twenty times as...

Phenotypic variation in diploid and tetraploid populations of Claytonia perfoliata (s.l.) (Portulacaceae)

Creator:: Miller, John M.
Abstract:: Meiotic chromosome counts from 200 populations of Claytonia (Montia) perfoliata (sensu lato) reveal a polyploid pillar complex based on three morphologically different, chemically distinct, and geographically defined diploids. The basic chromosome number is x=6. Diploid C. perfoliata Willdenow with linear juvenile leaves and deltoid mature basal leaves ranges southeastward from...

Analysis of the maize TOUSLED-LIKE KINASE gene family

Creator:: Yoon, Elizabeth S.
Abstract:: Protein kinases are an abundant class of enzymes which play important roles in numerous signal transduction systems. Arabidopsis TOUSLED kinase is a serine/threonine kinase which is essential for cell-cell communication within the shoot meristem. TOUSLED is encoded by a single gene in Arabidopsis. Recessive mutants in this gene show mild...

Purification and properties of the polygalacturonases produced by Fusarium oxysporum f. sp. lycopersici

Creator:: Harman, Gary Elvan, 1944-
Abstract:: This study was undertaken to determine the sorts of polygalacturonases present in the culture filtrate of Fusarium oxysporum f. sp. lycopersici, to purify and characterize these enzymes, and to study any complexes that may form between polygalacturonase and carbohydrate not degraded by the enzyme. The polygalacturonase in culture filtrate consists...

Biology of sweet cherry powdery mildew

Creator:: Calabro, Jill M.
Abstract:: The Pacific Northwest has become one of the nation’s premier sweet cherry, Prunus avium, production areas. As production of sweet cherries has flourished in Oregon and Washington, so has powdery mildew, caused by the fungus Podosphaera clandestina, which infects both foliage and fruit causing severe economic damage to growers. Sweet...

Port-Orford-cedar and Phytophthora lateralis : grafting and heritability of resistance in the host, and variation in the pathogen

Creator:: McWilliams, Michael G.
Abstract:: Port-Orford-cedar (Chamaecyparis lawsoniana) is a forest tree native to a small area of Oregon and California. A root disease caused by Phytophthora lateralis causes widespread mortality of Port-Orford-cedar. This dissertation examines three important elements of the Port-Orford-cedar P. lateralis pathosystem related to breeding for disease resistance: use of resistant rootstocks...
