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...

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...

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...

Identification of Endogenous and Exogenous Pararetroviruses in Red Raspberry (Rubus idaeus L.) and Blueberry (Vaccinium corymbosum L.)

Creator:: Diaz Lara, Alfredo
Abstract:: The Pacific Northwest (Oregon and Washington in the United States and British Columbia in Canada) is one of the major producers of red raspberry (Rubus idaeus L.) and blueberry (Vaccinium corymbosum L.) in the world. The expansion of growing area with these crops has resulted in the emergence of new...

Why pest plant control and native plant establishment failed : a restoration autopsy

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., Clark, Deborah Louise, 1950-, and Wilson, Mark G.
Abstract:: Explaining restoration failure can be as important as touting success. We used a series of studies to understand the failure of techniques commonly used to restore wetland prairies in the Willamette Valley of western Oregon. Burning, fallowing, and solarization (covering tilled plots with plastic sheeting to heat the soil) had...

Phylogeography and Evolution of Effector Genes in Phytophthora Species

Creator:: Shakya, Shankar K.
Abstract:: Plant pathogens in the genus Phytophthora are known to cause disease on field crops, nursery plants, and forest trees. The best known example probably is Phytophthora infestans, which triggered the infamous Irish potato famine. Other important Phytophthora species include: P. ramorum (sudden oak death pathogen), P. sojae (soybean root rot...

Systematics, phylogeny, and biogeography of the hysterangiales and related taxa (Phallomycetidae, Homobasidiomycetes)

Creator:: Hosaka, Kentaro
Abstract:: Monophyly of the gomphoid-phalloid clade was confirmed based on multigene phylogenetic analyses. Four major subclades (Hysterangiales, Geastrales, Gomphales and Phallales) were also demonstrated to be monophyletic. The interrelationships among the subclades were, however, not resolved, and alternative topologies could not be rejected statistically. Nonetheless, most analyses showed that the Hysterangiales...

Insights into the pathology and epidemiology of Phytophthora ramorum, causal agent of sudden oak death

Creator:: Daniels, Hazel A.
Abstract:: Sudden oak death is caused by the clonally reproducing generalist oomycete Phytophthora ramorum. The pathogen can infect more than 130 different plant hosts including Quercus spp., Larix kaempferi, and Notholithocarpus densiflorus, as well as common nursery genera such as Rhododendron and Camelia, where it causes symptoms ranging from bleeding cankers...
