Evolution and ecology of the Ceanothus-Frankia symbiosis

Creator:: Jeong, Soon-Chun
Abstract:: The evolutionary relationship between Frankia and actinorhizal plants was evaluated by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia strains. Although the branching order...

Conservation biology of Plagiobothrys hirtus (Boraginaceae) : evaluation of life history and population enhancement

Creator:: Amsberry, Kelly
Abstract:: Plagiobothrys hirtus (Boraginaceae) is a state and federally listed endangered plant found only in Douglas County, Oregon. This vernal pool endemic has historically been threatened by agricultural conversion of seasonal wetlands in the Sutherlin area, and is currently being eradicated as habitat is lost due to the rapid urban development...

Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

Creator:: Garrett, Karen A.
Abstract:: Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...

Taking the Next Step: Building an Arabidopsis Information Portal

Creator:: International Arabidopsis Informatics Consortium, Bastow, Ruth, Beynon, Jim, Brendel, Volker, Dooley, Rion, Friesner, Joanna, Grotewold, Erich, Huala, Eva, Loraine, Ann, Meyers, Blake, Pires, J. Chris, Provart, Nicholas, Stanzione, Dan, Town, Chris, and Ware, Doreen
Abstract:: The Arabidopsis Information Portal (AIP), a resource expected to provide access to all community data and combine outputs into a single user-friendly interface, has emerged from community discussions over the last 23 months. These discussions began during two closely linked workshops in early 2010 that established the International Arabidopsis Informatics...

Community Ecology and Population Genomics of Rhizopogon in the Madrean Sky Island Archipelago

Creator:: Piña Páez, Carolina G.
Abstract:: Anthropogenic induced climate change is predicted to alter distribution of existing plant populations. As plants migrate over space and time, populations often fragment and contract, affecting basic elements of population dynamics (e.g., population size, gene flow, genetic diversity, etc.). Little is known, however, how these impacts on plant species will...

Genetic diversity of the narrow endemic Astragalus oniciformis (Fabaceae)

Creator:: Alexander, J. Andrew, Liston, Aaron, and Popovich, Steve J.
Abstract:: Astragalus oniciformis Barneby is a narrow endemic xerophyte of the upper Snake River Plain of central Idaho, USA, where it inhabits stabilized, aeolian sand deposits and previously burned, sandy sites over Quaternary basalt flows. The objective of this study was to determine the levels and distribution of genetic differentiation within...

Functional groups, traits, and the performance of species in restoration

Creator:: Roberts, Rachael E. (Rachael Elaine)
Abstract:: In ecological restoration, species that are sown to increase the native plant diversity range in establishment ability. Some species readily establish, while others rarely do. This study set out to investigate some of the potential processes influencing species establishment, as well as the traits that are associated with the success...

Genetic diversity and interactions in populations of plants and pathogens

Creator:: Knott, Elizabeth A.
Abstract:: Two experiments involving interactions between wheat (Triticum aesitivium L.) cultivars and rust pathogens were investigated. One experiment evaluated the aggressiveness (measured by infection efficiency and latent period) of populations of Puccinia recondita Rob. when inoculated on the cultivar they were isolated from, their "own" cultivar, and when inoculated onto other...

The Role of Intraspecific Functional Trait Variation in the Differential Decline of Meadow Species Following Conifer Encroachment

Creator:: Celis, Jessica
Abstract:: In the Oregon Cascade Range, conifer encroachment has reduced the extent of mountain meadows by as much as 50% since the mid-1940s. Although encroachment results in a general decline of meadow species abundance and diversity, species differ in their sensitivities to encroachment: some show rapid declines whereas others persist in...

Ecology of Corydalis aquae-gelidae, a rare riparian plant

Creator:: Goldenberg, Douglas M.
Abstract:: Corydalis aquae-gelidae is a large herbaceous perennial in the Fumariaceae that has high habitat specificity. It is endemic to the western Cascade Range of Oregon and Washington, almost entirely on the Mt. Hood and Gifford Pinchot National Forests. It is a federal C2 candidate under the Endangered Species Act and...
