Systematics of the genus Ramaria inferred from nuclear large subunit and mitochondrial small subunit ribosomal DNA sequences

Creator:: Humpert, Andrea J.
Abstract:: Ramaria is a genus of epigeous fungi common to the coniferous forests of the Pacific Northwest of North America. The extensively branched basidiocarps and the positive chemical reaction of the context in ferric sulfate are distinguishing characteristics of the genus. The genus is estimated to contain between 200-300 species and...

The ERI-6/7 Helicase Acts at the First Stage of an siRNA Amplification Pathway That Targets Recent Gene Duplications

Creator:: Fischer, Sylvia E. J., Montgomery, Taiowa A., Zhang, Chi, Fahlgren, Noah, Breen, Peter C., Hwang, Alexia, Sullivan, Christopher M., Carrington, James C., and Ruvkun, Gary
Abstract:: Endogenous small interfering RNAs (siRNAs) are a class of naturally occuring regulatory RNAs found in fungi, plants, and animals. Some endogenous siRNAs are required to silence transposons or function in chromosome segregation; however, the specific roles of most endogenous siRNAs are unclear. The helicase gene eri-6/7 was identified in the...

Taxonomic Clarification of Lupinus oreganus and Lupinus biddlei in the Pacific Northwest, USA

Creator:: Severns, Paul M., Meyers, Stephen C., and Tran, Tri
Abstract:: Through a phylogenetic study Using LECCYCIA nucleotide sequences and a survey of historical Botanical literature, we propose clarifications in the nomenclature of Lupinus oreganus and Lupinus biddlei. The former taxon has been incorrectly classified as Lupinus sulphurcus ssp. kincaidii and recently as L. oreganus var. kincaidii. The latter has recently...

Restoration of native upland prairies: Habitat for Fender’s blue butterfly (Icaricia icarioides fenderi)

Creator:: Clark, Deborah Louise, 1950- and Wilson, Mark V.
Abstract:: Our project goal is to promote the abundance of the endangered Fender’s blue butterfly (Icaricia icarioides fenderi) by recreating upland prairie habitat in former agricultural land at Finley National Wildlife Refuge, Corvallis, Oregon. To achieve this goal we initiated the following three studies. Study One: Experimental Investigation on the Effectiveness...

Fire and Grazing Influence Site Resistance to Bromus tectorum Through Their Effects on Shrub, Bunchgrass and Biocrust Communities in the Great Basin (USA)

Creator:: Condon, Lea A. and Pyke, David A.
Abstract:: Shrubs, bunchgrasses and biological soil crusts (biocrusts) are believed to contribute to site resistance to plant invasions in the presence of cattle grazing. Although fire is a concomitant disturbance with grazing, little is known regarding their combined impacts on invasion resistance. We are the first to date to test the...

Compost teas and compost amended container media for plant disease control

Creator:: Scheuerell, Steven J.
Abstract:: The primary goal of this dissertation research was to assess the use of compost for the control of several foliar and soil borne diseases commercially important in the Pacific Northwest. The use of compost teas to control of gray mold (Botrytis cinerea) on geraniums, powdery mildew (Podosphearapannosa var. rosae), rust...

Seedborne Phytophthora infestans : effect of pathogen clonal lineage and potato cultivar on seed transmission of late blight and plant growth responses

Creator:: Partipilo, Heather M.
Abstract:: Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission rate across potato cultivars was 0.5 and 2.4% with US-8, and 0.8 and 1.0% with US-11 in 1999...

Effects of the Mycoparasite Sphaerellopsis filum on Overwintering Survival of Stem Rust in Perennial Ryegrass

Creator:: Gordon, T. C. and Pfender, W. F.
Abstract:: Sphaerellopsis filum is a mycoparasite of Puccinia graminis subsp. graminicola, a rust fungus that causes widespread crop damage on perennial ryegrass grown for seed. In observations taken over the winter months, S. filum was found naturally colonizing 2% of P. graminis subsp. graminicola uredinia on first-year plantings and 25% of...
