Histological comparisons of needle tissues of four species of white pine infected by Cronartium ribicola

Creator:: Sweeney, Katarina
Abstract:: Hypersensitive response-like (HR-like) needle reactions to infection by the white pine blister rust pathogen, Cronartium ribicola, have been reported for several species of five needle pines native to western North America. The best-studied examples are in Pinus monticola and P. lambertiana. In these species a "needle spot" phenotype has been...

Identifying the relevance of "family forest" wood product origin and environmental certification for Oregon consumers, and specifiers and industrial customers

Creator:: Hamner, Rebecca A.
Abstract:: The wood products industry is influenced heavily by family ownership along the entire value chain. Although family ownership affects each link of the wood products value chain, there has been little research into the importance of products originating from family forestland. Specific attributes of products, such as origin or environmental...

Histological examination of Phytophthora ramorum in Notholithocarpus densiflorus bark tissues

Creator:: Botts, Molly M.
Abstract:: Colonization of N. densiflorus tissues by P. ramorum is not well understood. The pathogen is able to colonize nearly all tissues of this host but it is unclear how a tree is ultimately killed. Because this is such a destructive invasive pathogen, it is important to investigate its pathogenic strategy....

Environmental factors influencing the rate of spread of Phellinus weirii (Murr.) Gilbertson in young-growth Douglas-fir

Creator:: Angwin, Peter A.
Abstract:: Studies to identify the environmental factors that influence the rate of ectotrophic mycelial growth of Phellinus weirii (Murr.) Gilbertson along Douglas-fir roots were undertaken both in the laboratory and in the field. The effects of soil pH, nitrogen, moisture, temperature, microorganisms and bulk density were investigated. In the lab, the...

Phytosanitation of Douglas-fir (Pseudotsuga menziesii) logs to mitigate the risk of artificially disseminating Phytophthora ramorum within the global trade of timber

Creator:: Hulbert, Joseph M.
Abstract:: Phytophthora ramorum is a plant pathogen that was accidentally introduced to the United States. This invasive microorganism has killed over a million trees in California and Oregon, and continues to spread to new areas. Diseased areas have been nationally quarantined to prevent further spread and more than ninety countries include...

Characterizing the Plant-Associated Symbionts, Rhodococcus and Agrobacterium

Creator:: Fuller, Skylar L.
Abstract:: Symbioses are a spectrum of interactions between organisms living in closeassociation. These intimate interactions range from mutualism, in which bothorganisms benefit, to parasitism, where one organism benefits at the expense ofthe other. Horizontal gene transfer is the acquisition of genes independent ofvertical transmission and demonstrably promotes the transition of bacteria...

Effect of intervention strategies on specific verbal feedback of volunteers and its secondary effect on qualitative motor performance

Creator:: Gately, Jeanne E.
Abstract:: The purpose of this study was twofold. First, to determine if planned interventions could increase untrained undergraduate students' use of positive and specific skill feedback while a teaching fundamental motor skill to children who are disabled. Second, to qualitatively assess the effect of specific verbal feedback on student motor performance....

Contractile function and calpain activity in mouse skeletal muscle during hypoxia

Creator:: Hu, Hui
Abstract:: Calcium activated proteases, or calpains, are activated in cardiac muscles under conditions of ischemia/reperfusion and hypoxia. Their activity in skeletal muscle under similar conditions is poorly understood. We tested the hypothesis that hypoxia elevates calpain-mediated proteolysis in isolated glycolytic (extensor digitorum longus, EDL) and oxidative (soleus, SOL) mouse muscles studied...

The infection and colonization of Douglas-fir needles by the Swiss needle cast pathogen, Phaeocryptopus gaeumannii (Rhode) Petrak

Creator:: Capitano, Bryan R.
Abstract:: Phaeocryptopus gaeumannii is a pathogenic fungus on Douglas-fir needles which has become a serious threat to timber production in the last decade along the Oregon coast This research was undertaken to describe the general biology and pathology of F. gaeumannii on Douglas-fir needles and how environmental variables affect fungal development....

Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....
