Generation of full-length cDNA clone and functional analysis of leader proteases of grapevine leafroll-associated virus-2

Creator:: Liu, Yu-Ping
Abstract:: Papain-like leader proteases are found in diverse families of human, animal, plant, and fungal positive-strand RNA viruses. In addition to autocatalytic processing, these proteases play a variety of roles in the virus life cycle. In particular, the leader protease (L-Pro) of a prototype member of the Closterovirus genus, Beet yellows...

Propagule sources, disturbance characteristics and the inital establishment of riparian vegetation after debris flows

Creator:: Gecy, Jeanne Leslie
Abstract:: Debris flows are a major cause of disturbance to riparian vegetation. Both observational and experimental studies were used to examine the initial recovery of riparian vegetation after debris flows on headwater streams in the western Cascades of Oregon. My goal was to determine the roles of seedlings and vegetative sprouts,...

The effects of nitrogen manipulations and hydrology on the establishment and competitive abilities of wetland prairie plant species (western Oregon)

Creator:: Davis, Kimberly J.
Abstract:: Many studies suggest that weedy plant species are most successful when soil nitrogen in abundant. Consequently, I used soil nitrogen manipulations to determine if altering nitrogen would affect the establishment of both weedy and native plant species in a western Oregon wetland prairie. In two studies, we added carbon amendments...

Multiple functions of a proteinase in closterovirus life cycle

Creator:: Peng, Chih-Wen
Abstract:: More than half of the recognized genera of positive strand RNA viruses employ polyprotein processing as one of the strategies for their genome expression. Normally, this processing is mediated by virus-encoded proteinases that belong to the trypsin-like or papain-like family. In particular, papain-like, leader proteinases were found in diverse families...

Phylogenetics and genomic patterns of speciation in Pinus with an empahsis on subgenus Strobus

Creator:: Syring, John V.
Abstract:: Data from nuclear ribosomal internal transcribed spacer regions (nrITS) and chloroplast DNA (cpDNA) have failed to resolve phylogenetic relationships in Pinus. To provide greater interspecific resolution, five low-copy nuclear genes were developed from mapped conifer anchor loci. Four genes were sequenced from species representing all Pinus subsections. Individual loci do...

Conservation genetics of Kincaid's lupine : a threatened plant of western Oregon and southwest Washington grasslands

Creator:: Severns, Paul M.
Abstract:: Kincaid's lupine (Lupinus oreganus Heller) is a federally listed threatened species native to remnant grassland of western Oregon and southwestern Washington, and is the primary larval host plant of a once thought extinct butterfly, Plebejus icarioides fenderi Macy. Past studies concerning Kincaid's lupine reproduction suggested that populations may suffer reductions...

Virus-Derived Gene Expression and RNA Interference Vector for Grapevine

Creator:: Kurth, Elizabeth G., Peremyslov, Valera V., Prokhnevsky, Alexey I., Kasschau, Kristin D., Miller, Marilyn, Carrington, James C., and Dolja, Valerian V.
Abstract:: The improvement of the agricultural and wine-making qualities of the grapevine (Vitis vinifera) is hampered by adherence to traditional varieties, the recalcitrance of this plant to genetic modifications, and public resistance to genetically modified organism (GMO) technologies. To address these challenges, we developed an RNA virus-based vector for the introduction...

Spatial and chronological patterns of Purshia tridentata as influenced by Pinus ponderosa overstory

Creator:: Sherman, Robert James
Abstract:: Twelve sites of uniform topography and soils were selected in the Pinus ponderosa/Purshia tridentata/Festuca idahoensis Association. These sites were located in the rain shadow on the east flank of the Oregon Cascades. A fire history in the form of fire scars on ponderosa pine was available for nine of these...

The genus Leucogaster (Basidiomycetes, Leucogastraceae)

Creator:: Fogel, Robert Dale
Abstract:: Three provisional species are described as new: Leucogaster couchii, L. gelatinosus, and L. microsporus. Leucophlebs candida is transferred to Leucogastef, completing the transfer of all Leucophlebs species to Leucogaster. L. columellatus is transferred to Sclerogaster. L. longisterigmatus is synonymized with L. rubescens, L. foveolatus with L. odoratus, and L. fulvimaculatus...
