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...

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...

Honeggeriella complexa gen. et sp. nov., a heteromerous lichen from the lower cretaceous of Vancouver Island (British Columbia, Canada)

Creator:: Matsunaga, Kelly K. S., Stockey, Ruth A., and Tomescu, Alexandru M. F.
Abstract:: • Premise of the study: Colonists of even the most inhospitable environments, lichens are present in all terrestrial ecosystems. Because of their ecological versatility and ubiquity, they have been considered excellent candidates for early colonizers of terrestrial environments. Despite such predictions, good preservation potential, and the extant diversity of lichenized...

A Perithecial Sordariomycete (Ascomycota, Diaporthales) from the Lower Cretaceous of Vancouver Island, British Columbia, Canada

Creator:: Bronson, Allison W., Klymiuk, Ashley A., Stockey, Ruth A., and Tomescu, Alexandru M. F.
Abstract:: A perithecial ascomycete, Spataporthe taylori gen. et sp. nov., represented by >70 sporocarps is preserved by cellular permineralization in marine carbonate concretions dated at the Valanginian-Hauterivian boundary (Early Cretaceous) from Vancouver Island, British Columbia, Canada. The spheroid perithecia with lumina 330–470 µm wide and 220–320 µm high are densely distributed...

The genome of the xerotolerant mold Wallemia sebi reveals adaptations to osmotic stress and suggests cryptic sexual reproduction

Creator:: Padamsee, Mahajabeen, Kumar, T. K. Arun, Riley, Robert, Binder, Manfred, Boyd, Alex, Calvo, Ana M., Furukawa, Kentaro, Hesse, Cedar, Hohmann, Stefan, James, Tim Y., LaButti, Kurt, Lapidus, Alla, Lindquist, Erika, Lucas, Susan, Miller, Kari, Shantappa, Sourabha, Grigoriev, Igor V., Hibbett, David S., McLaughlin, David J., Spatafora, Joseph W., and Aime, M. Catherine
Abstract:: Wallemia (Wallemiales, Wallemiomycetes) is a genus of xerophilic Fungi of uncertain phylogenetic position within Basidiomycota. Most commonly found as food contaminants, species of Wallemia have also been isolated from hypersaline environments. The ability to tolerate environments with reduced water activity is rare in Basidiomycota. We sequenced the genome of W....

Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:: David, Nicholas L.
Abstract:: Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...

Assessment of potato tuber blight caused by Phytophthora infestans

Creator:: Glass, Jenny Rebecca
Abstract:: Late blight, caused by Phytophthora infestans, is a devastating problem to potato production in many parts of the world. While the foliar phases of this disease are well characterized, tuber infection, leading to quality losses and disease perpetuation, is less well understood. Experiments were conducted during 1998 and 1999 in...

A ranunculalean liana stem from the cretaceous of British Columbia, Canada: Atli morinii gen. et sp nov.

Creator:: Smith, Selena Y., Little, Stefan A., Cooper, Ranessa L., Burnham, Robyn J., and Stockey, Ruth A.
Abstract:: Premise of research. The lianoid habit is found in 125 extant plant families and is most diverse and abundant in structurally complex forests, such as tropical forests. A stem with lianoid anatomy is described from Cretaceous sediments of Hornby Island, British Columbia. Methodology. The stem segment, 2.5 cm in diameter...

Expression of secondary metabolites following manipulations of the C:N ratio in spotted knapweed, Centaurea maculosa Lam.

Creator:: Brodhagen, Marion L.
Abstract:: Spotted knapweed, Centaurea maculosa Lam. (Compositae) is an extremely successful introduced weed species in the northwestern United States. Multiple factors may be responsible for its success, including chemical defense. Two different types of putative chemical defense agents are the focus of this thesis. The first is a bitter-tasting sesquiterpene lactone,...

Phenotypic Plasticity of the Hydrasperman Seed Fern Tetrastichia bupatides Gordon (Lyginopteridaceae)

Creator:: Dunn, Michael T. and Rothwell, Gar W.
Abstract:: Fifty-nine stems of Tetrastichia bupatides, numerous frond segments, and roots from Oxroad Bay, Scotland, have recently been analyzed. They reveal that many characters originally used to describe this species exhibit a wider range of variation than previously suspected. These data suggest that ribs of the protostele are most commonly four...
