The detection of ilarvirus (subgroup B) by enzyme-linked immunosorbent assay

Creator:: McMorran, Jeffrey P.
Abstract:: The reliability and sensitivity of enzyme-linked immunosorbent assay (ELISA) in the detection of ilarvirus (isometric labile ringspot virus) subgroup B and prune dwarf virus (PDV) isolates in Prunus and Malus species has been well established. To use this technique in large scale virus indexing programs more information was required on...

Effect of resident epiphytic fungi development of brown rot blossom blight of stone fruits

Creator:: Wittig, Hans P. P.
Abstract:: Antagonistic effects of Epicoccum purpurascens, Aureobasidium pullulans, Trichoderma spp., and Botrytis cinerea on establishment of Monilinia fructicola infections in cherry and peach blossoms were assessed in field and mist chamber studies. Conidia of each fungus were applied to blossoms that were subsequently inoculated with conidia of M fructicola. Mist chamber...

Analysis and prediction of patterns in lichen communities over the western Oregon landscape

Creator:: Peterson, Eric B.
Abstract:: The diverse lichen flora of the Pacific Northwest is being impacted by population growth and by forest management practices. Accumulating information about our lichen flora will improve our conservation strategies. This dissertation first collects information to improve our understanding of how lichen communities vary among forests of differing structure, and...

Addressing the relationship between Pseudoperonospora cubensis and P. humuli using phylogenetic analyses and host specificity assays

Creator:: Mitchell, Melanie N.
Abstract:: The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...

Identification of Genetic Variation between Obligate Plant Pathogens Pseudoperonospora cubensis and P-humuli Using RNA Sequencing and Genotyping-By-Sequencing

Creator:: Summers, Carly F., Gulliford, Colwyn M., Carlson, Craig H., Lillis, Jacquelyn A., Carlson, Maryn O., Cadle-Davidson, Lance, Gent, David H., and Smart, Christine D.
Abstract:: RNA sequencing (RNA-seq) and genotyping-by-sequencing (GBS) were used for single nucleotide polymorphism (SNP) identification from two economically important obligate plant pathogens, Pseudoperonospora cubensis and P. humuli. Twenty isolates of P. cubensis and 19 isolates of P. humuli were genotyped using RNA-seq and GBS. Principle components analysis (PCA) of each data...

Modification of phyllosphere environments to enhance establishment of Gliocladium roseum, an antagonist of Botrytis cinerea

Creator:: Bennett, Robert J. (Robert Joe), 1953-
Abstract:: Radial colony growth of three isolates of Gliocladium roseum and three isolates of Bottytis cinerea were measured on 1/4 strength potato dextrose agar amended with concentrations of NaHCO₃ ranging from 0-2% (w/v). Compared to the control, reductions in colony diameter of the B. cinerea isolates ranged from 60-79% and 73-89%...

Epiphytic yeasts isolated from apple leaves to control of gray and blue mold fruit rots of apple

Creator:: Falconi, Cesar E.
Abstract:: Eight phylloplane yeasts were isolated from backyard apple trees in Corvallis, OR. Yeast isolates were classified to genus or species level. All isolates were tested in vitro for antagonistic activity against the postharvest pathogens Botrytis cinerea and Penicillium expansum. Of these isolates, Aureobasidium pullulans, Sporobolomyces roseus Rhodotorula sp., consistently reduced...

Lichen response to the environment and forest structure in the western Cascades of Oregon

Creator:: Martin, Erin P.
Abstract:: Lichens are an important part of the biota in western Oregon forests, where they perform valuable ecological roles and contribute significantly to biodiversity. Lichens in western Oregon are threatened by a number of factors including air pollution and land use practices. If we wish to maintain the persistence of lichens...
