Physiology of senescence of the shoot apex in Pisum sativum L.

Creator:: Ecklund, Paul Richard, 1941-
Abstract:: Shoot apex senescence is defined as the collective progressive and deteriorative processes which ultimately terminate the functional life of the shoot apex. Senescence of shoot apices of Pisum sativum L. 'Alaska' as measured by cessation of stem elongation was delayed by removal of flowers and by treatment with gibberellin A₃...

Effects of host resistance on Mycosphaerella graminicola populations

Creator:: Cowger, Christina
Abstract:: Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...

Understanding Host-Pathogen Interactions in the Sphaerulina musiva-Populus Pathosystem

Creator:: Dunnell, Kelsey Liann
Abstract:: Host-parasite interactions between the pathogen, Sphaerulina musiva, and its host, Populus spp., were examined in a series of studies. In the first study, variation in resistance of Populus nigra from 7 locations in Europe was differentiated based on the parameters cankers per cm and disease severity score. The analysis evaluated...

Candidate Genes Associated with Blister Rust Resistance in Whitebark Pine (Pinus albicaulis) Revealed through de novo Transcriptome Assembly and Differential Gene Expression Analysis

Creator:: Bair, Zolton J.
Abstract:: Whitebark pine (Pinus albicaulis) is an iconic North American high-elevation tree species currently threatened by climate change, mountain pine beetle, and white pine blister rust (WPBR), a lethal disease caused by the non-native fungal pathogen Cronartium ribicola. In collaboration with the USDA Forest Service Dorena Genetic Resource Center, germplasm was...
Resource Type:: Dissertation

Landscape Genomics and Climatic Responses of Willamette Valley Alders

Creator:: Kral, George L.
Abstract:: The climate of the Pacific Northwest is in flux, and existing forest ecosystems are stressed and poised to shift in fundamental ways, with or without human intervention. This dissertation probes the nature of forest responses to environmental change through investigations of morphology and genetics of three species of alder co-occurring...

Identification and Occurrence of Sweet Cherry (Prunus avium) Virus and Virus-Like Diseases in Various Regions and Orchards of Oregon

Creator:: Reinhold, Lauri A.
Abstract:: There are over 35 known virus and virus-like diseases of sweet cherry (Prunus avium), some with potential to cause severe economic impact by reducing vegetative growth, vigor, and/or quality of fruit. Oregon is the second-ranked state for sweet cherry production in the United States with 13,000 acres and $70.8 million...

Unearthing the Cretaceous Diversification of Cornales

Creator:: Atkinson, Brian A.
Abstract:: The order Cornales (dogwoods) is the earliest diverging lineage within the most diverse group of flowering plants, the asterids (>80,000 species). Although molecular phylogenetics have significantly improved our understanding of cornalean systematics, early phylogenetic relationships remain uncertain due to an initial rapid radiation. The fossil record of Cornales is extensive...

Analysis of putative elements of plant signal transduction chains

Creator:: Verhey, Steven D.
Abstract:: The thesis begins with an introduction to signal transduction and an analysis of current understanding of plant signal transduction. There are similarities between plants and animals, but also key differences, including lack of protein kinase C and of a cAMP signaling pathway in plants, and presence in plants of calcium...

Diagnosis and Etiology of a Soilborne Disease Complex of Winter Squash (Cucurbita maxima) in the Willamette Valley, OR

Creator:: Rivedal, Hannah M.
Abstract:: Winter squash (Cucurbita maxima) grown in Oregon’s Willamette Valley for edible seed, frozen foods, and fresh markets is susceptible to an undiagnosed soilborne disease. Diseased squash fields exhibit symptoms of stunting, root and crown rot, vascular discoloration, and late-season wilt, which in extreme cases can lead to total crop failure....
