Comparison of the water relations characteristics of woody plants in western Oregon

Creator:: Davis, Kent J.
Abstract:: I studied the water relations traits, twig conductivity, C'3 isotopic composition, and wood density of three conifer and five angiosperm species in western Oregon. This study took place from spring 2002 to fall 2003 on four sites. Species were selected to represent the diversity of drought tolerance of woody plants...

Genomic comparisons of seed-transmissible and non-seed-transmissible strains of cucumber mosaic virus

Creator:: Ried, Jeffrey L.
Abstract:: A sensitive assay for the analysis of contaminating segments in pseudorecombinants constructed from a seed-transmissible (CVM-Pg) and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic virus was developed using partial RNase T₁ digestion. Isolated genomic RNA segments produced unique digestion patterns when 3'- end labeled, treated with RNase T₁, and subjected...

Serological and molecular approaches for distinguishing bean common mosaic and bean common mosaic necrosis potyviruses and their respective pathogroups

Creator:: Xu, Ling, 1963-
Abstract:: Polyclonal antisera were raised against isolates of bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) using conventional serological methods. Infected tissues containing, respectively, 22 recognized BCMV and BCMNV isolates were tested against the two antisera by antigen-coated plate (ACP) ELISA and double antibody sandwich (DAS) ELISA....

Effect of iron on biological control of fire blight by Pseudomonas fluorescens A506

Creator:: Temple, Todd N.
Abstract:: Competitive exclusion has been the mechanism hypothesized to account for the biological control of fire blight disease of pear and apple by the bacterium Pseudomonas fluorescens A506 (A506). Recent laboratory assays demonstrated, however, that A506 produces an antibiotic that is toxic to the fire blight pathogen, Erwinia amylovora, when cultured...

Improving Best Management Practices for Potato Production in the Columbia Basin : An Evaluation of Essential Oils for Control of Verticillium Wilt and the Fate of Chloride in the System

Creator:: Light, Sarah Elizabeth
Abstract:: Although the potato (Solanum tuberosum L.) is a global crop, few growing regions rival the high yields of the Columbia Basin of Eastern Oregon and Washington. Two research projects were conducted in Hermiston, OR to contribute to best management practices for the region. The first project evaluated the efficacy of...

Factors influencing the production and survival of inoculum of Elytroderma deformans

Creator:: Laird, Peter Paul
Abstract:: This study concerns factors affecting production and survival of ascospores of Elytroderma deformans (Weir) Darker, a needle cast of ponderosa pine (Pinus ponderosa Laws.). The results show that summer cooling and a reduction in host vigor delays and diminishes the number of fertile hysterothecia produced. Evidence is offered for classification...

The roles of Verticillium dahliae, Colletotrichum atramentarium, Erwinia carotovora subsp. carotovora and E. carotovora subsp. atroseptica in "early dying" disease of potatoes

Creator:: Kirkland, Marjorie Lynn
Abstract:: The primary cause of "early dying" disease of potatoes in Oregon is Verticillium dahliae; however, Colletotrichum atramentarium, Erwinia carotovora subsp. carotovora (Ecc) and E. carotovora subsp. atroseptica (Eca) are also commonly isolated from diseased plants. Therefore, field and greenhouse studies were initiated to determine the relative involvement of each pathogen,...

Effect of a broccoli green manure, soil solarization, and isolates of Verticillium dahliae on Verticillium wilt of agronomic and nursery crops

Creator:: Berlanger, Ingrid E.
Abstract:: Green manures, soil solarization, and long rotations with crops not susceptible to Verticillium wilt are among the disease management tactics currently under investigation as alternatives to chemical fumigation of soil. The effect of a broccoli green manure on soil microsclerotial populations of three isolates of Verticillium dahliae and on Verticillium...

Double-stranded RNA isolated from grapevine affected by grapevine stem-pitting disease

Creator:: Walter, Michael H.
Abstract:: Nucleic acid extracted from dormant cane phloem of grapevines affected by grapevine stem-pitting disease (SP) formed a high molecular weight (MW) band on 1.0% and 0.8% agarose gels. The band was unique to diseased vines. Other bands appeared from samples of both diseased and virus-free vines, but did not associate...
