A systematic study of Lathyrus vestitus Nutt. ex T. & G. (Fabaceae) and allied species of the Pacific Coast

Creator:: Broich, Steven L.
Abstract:: Eight species of Lathvrus (Fabaceae, Faboideae) endemic to the Pacific Coast of North America were the subject of a systematic investigation. Taxa studied included Lathvrus vestitus, Nutt. ex T. & G., L. laetif lorus Greene, L.. iepsonii Greene, £,. splendens Kellogg, L. polvphvllus, Nutt. ex T. & G., L. holochlorus...

A G-type Lectin Receptor-like Kinase Associated with Septoria Canker Resistance and Susceptibility Described using Multi-omics and Biotechnology

Creator:: Lenz, Ryan R.
Abstract:: Managers of forest and plantation ecosystems are encountering growing problems involving plant pathogens and the expanding geographic ranges of these pathogens. Historically unexposed stands are exceptionally vulnerable when a non-native pathogen is introduced because these pathogens can cause devastating disease in a host population that lacks co-evolved resistance mechanisms. One...

Non-target Effects of Biological Control: Ecological Risk of Tyria jacobaeae (Lepidoptera: Erebidae) to Senecio triangularis (Asteraceae) in Western Oregon

Creator:: Rodman, Madison G.
Abstract:: Non-target effects are one of the greatest potential risks of weed biological control programs, and understanding non-target effects of biological control at the population level is crucial for predicting when they will occur and altering the perception of biological control as a whole. In this thesis, we assessed the ecological...

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....

The Effect of Iron Limitation on the Transcriptome and Proteome of Pseudomonas fluorescens Pf-5

Creator:: Lim, Chee Kent, Hassan, Karl A., Tetu, Sasha G., Loper, Joyce E., and Paulsen, Ian T.
Abstract:: One of the most important micronutrients for bacterial growth is iron, whose bioavailability in soil is limited. Consequently, rhizospheric bacteria such as Pseudomonas fluorescens employ a range of mechanisms to acquire or compete for iron. We investigated the transcriptomic and proteomic effects of iron limitation on P. fluorescens Pf-5 by...

Latent homology and convergent regulatory evolution underlies the repeated emergence of yeasts

Creator:: Nagy, László G., Ohm, Robin A., Kovács, Gábor M., Floudas, Dimitrios, Riley, Robert, Gácser, Attila, Sipiczki, Mátyás, Davis, John M., Doty, Sharon L., de Hoog, G Sybren, Lang, B. Franz, Spatafora, Joseph W., Martin, Francis M., Grigoriev, Igor V., and Hibbett, David S.
Abstract:: Convergent evolution is common throughout the tree of life, but the molecular mechanisms causing similar phenotypes to appear repeatedly are obscure. Yeasts have arisen in multiple fungal clades, but the genetic causes and consequences of their evolutionary origins are unknown. Here we show that the potential to develop yeast forms...

Ozone flux in Helianthus annuus (L.)

Creator:: Smith, Elaine D.
Abstract:: Sunflower (Helianthus annuus L., cv. NK894) seedlings, grown hydroponically, were exposed to ozone concentrations of 0.0, 0.1, 0.2, and 0.3 ppm at 60% RH, or 0.0 and 0.3 ppm at 30% and 90% RH, for 6 h/d, for four consecutive days, at ages 15 to 18 days from seeding. Plant...

Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...

Variation of drought resistance and root regeneration among genotypes of Port-Orford-cedar (Chamaecyparis lawsoniana)

Creator:: Sharpe, Jodie M.
Abstract:: Drought resistance among genotypes of Port-Orford-cedar (Chamaecyparis lawsoniana (A. Murr.) Pan., Cupressaceae) seedlings was evaluated both in the field and in the greenhouse. Field water potentials (Ψ) of 5-year-old seedlings were measured at two high-elevation plantation sites where summer drought occurs. Measurements of Ψ were compared to survival two years...
