Host plant dependent disease progression of the microsporidian parasite Nosema tyriae on Cinnabar moth larvae

Creator:: Berns, Kathryn, Buergi, Linda, and McEvoy, Peter
Abstract:: Tyria jacobaeae was introduced as a biological control agent to control the noxious weed Jacobea vulgaris. Eventually introduced to the Cascade mountain range of Oregon, T. jacobaeae has been found to feed on Senecio triangularis, a native plant closely related to J. vulgaris. Nosema tyriae is a parasitic fungus under...

Characterizing novel bacterial isolates that inhibit the growth of gall-forming phytopathogenic bacteria

Creator:: Belcher, Michael S.
Abstract:: Agrobacterium tumefaciens and Rhodococcus fascians are plant pathogenic bacteria that can induce crown and leafy galls on plants, respectively. Infection by these bacteria results in disfigured, unsellable plants, leading to significant economic losses to the nursery industry. A. tumefaciens and R. fascians are capable of infecting a broad range of...

A NERD-Exocyst Interaction Facilitates the Growth of Roots and Root Hairs in Arabidopsis

Creator:: Moussaoui, Ibrahim
Abstract:: The growth of a plant’s root system is essential for its survival. Preliminary observations suggest that a protein complex called the exocyst may play a role in the development of the root system by facilitating the growth of roots and root hairs. Previous work discovered a protein that potentially interacts...

Benthic marine algae on Japanese tsunami marine debris – a morphological documentation of the species. Part 3 - The green algae and cyanobacteria

Creator:: Hansen, Gayle I.
Abstract:: To determine the invasion threat to the NE Pacific of marine algae arriving on Japanese debris from the 2011 Great Tōhoku Earthquake and Tsunami, my colleagues and I identified the algal species on 42 of the most heavily fouled debris items that landed on the shores of Oregon and Washington...

Patterns in the occupancy and abundance of the globally rare lichen Erioderma pedicellatum in Denali National Park and Preserve, Alaska

Creator:: Stehn, Sarah E., Nelson, Peter R., Roland, Carl A., and Jones, Jennifer R.
Abstract:: We investigated habitat attributes related to the occupancy of the globally rare and endangered epiphytic lichen, Erioderma pedicellatum, in a newly discovered (2009) population center in Denali National Park and Preserve (DNPP), Alaska. We measured forest, tree and epiphytic lichen community characteristics on eighty-five systematically selected plots in four study...

Characterization, epidemiology, and ecology of a virus associated with black raspberry decline

Creator:: Halgren, Anne B.
Abstract:: The objective of this study was to characterize an unknown agent associated with decline in black raspberry (Rubus occidentalis) in Oregon. A virus was found consistently associated with decline symptoms of black raspberries and was named Black raspberry decline associated virus (BRDaV). Double stranded RNA extraction from BRDaV-infected black raspberry...

Contrasting Epiphytic and Ground Layer Macrolichen Communities along the Coast-to-inland Climatic Gradient in Oregon

Creator:: Glauser, Abby L.
Abstract:: Cyanolichens, lichens with a cyanobacterial photobiont, benefit our ecosystems by the fixation of atmospheric nitrogen into a usable form for other organisms. They are highly sensitive to air pollution and require liquid water for photosynthesis. Many cyanolichen species frequently occur on the ground in the Pacific Northwest, however, most macrolichen...

Interactive effects of stripe rust and plant competition in heterogeneous wheat populations

Creator:: Finckh, Maria Renate
Abstract:: Disease has been implied as an important selective force acting in plant populations. This study was conducted to determine the effects of stripe rust (Puccinia striiformis) on the population dynamics of wheat (Triticum aestivum) cultivar mixtures. Five wheat cultivars were grown in pure stands and all possible mixtures at three...

Potential susceptibility of tanoak associated and rare ericaceous plant species of southwestern Oregon to Phytophthora ramorum

Creator:: Zanzot, James W.
Abstract:: The sudden oak death pathogen, Phytophthora ramorum, is present in southwestern Oregon, and while an eradication effort is underway, the potential impact of the polyphagous pathogen on surrounding vegetation is unknown. Plant communities in the area are substantially different from those affected in California, although tanoak (Lithocarpus densiflorus), evergreen huckleberry...
