Purification and partial characterization of a virus associated with korogwe leaf spot disease of sisal

Creator:: Mpunami, Anatolia
Abstract:: Sisal Wave sisalana Perrine), one of Tanzania's main cashcrops, is severely affected by korogwe leaf spot disease (KLS).Infected plants show chocolate brown, concentric, scablike eruptions on both surfaces of mature leaves, and produce stained, low-quality fiber. A flexuous, rod-shaped virus was isolated from KLS-infected sisal leaves and studied at Oregon...

Genetic recombination of the integrative plasmid pMC7105 of Pseudomonas syringae pv. phaseolicola involves repetitive sequences

Creator:: Szabo, Leslie J.
Abstract:: A strain of the phytopathogenic bacterium Pseudomonas syringae pv. phaseolicola, a pathogen of common bean Phaseolus vulgaris, harbors a 150 kilobase pair (kb) plasmid pMC7105. In one strain, LR719, pMC7105 is stably integrated in the bacterial chromosome. Imprecise excision of the pMC7105 replicon has been shown to result in the...

Lichen communities and caribou habitat in Denali National Park and Preserve, Alaska, USA

Creator:: Nelson, Peter R.
Abstract:: Lichens play many important roles in subarctic terrestrial ecosystems by fixing nitrogen, colonizing rock and gravel, stabilizing otherwise bare soil, adding significantly to vegetation biodiversity and serving as the primary food for caribou in the winter. In these chapters, I analyzed lichen community and ecological trait structure along environmental gradients,...

Nursery, cold storage, and field studies on western conifers inoculated with spores of Pisolithus tinctorius

Creator:: Alvarez, Isabel Fernandez
Abstract:: Inoculations of white fir, Shasta red fir, Douglas fir and ponderosa pine with Pisolithus tinctorius spores when outplanted failed to produce P. tinctorius mycorrhizae at the end of the first growing season. In the third year a few P. tinctorius mycorrhizae were formed on white fir. Inoculations reduced seedling survival...

Conservation of Rorippa columbiae : an evaluation of reintroduction potential through the study of germination ecology, propagation methods, and habitat requirements

Creator:: Kentnesse, Laura E.
Abstract:: Rare plant reintroductions are a critical conservation tool for the augmentation of diminishing populations, or re-establishment of extirpated populations. Analysis of reintroduction failures suggests that a sophisticated understanding of species biology, ecology, and habitat is essential for producing self-sustaining rare plant populations. This study sought to generate that background knowledge...

Occurrence, transmission, and properties of strains of cucumber mosaic virus that are seed-transmitted in Phaseolus vulgaris

Creator:: Davis, Robert Francis
Abstract:: A survey of major bean (Phaseolus vulgaris) breeding programs and seed producing areas in Idaho, Washington, and Oregon was conducted to determine the occurrence of cucumber mosaic virus (CMV), recently reported to be seedborne in beans. Some 259 plants, sampled from breeding lines of diverse germplasm, were found by enzyme-linked...

Susceptibility of Pacific yew (Taxus brevifolia Nutt.) to Phytophthora lateralis

Creator:: Murray, Marion S.
Abstract:: In 1991 Pacific yew (Taxus brevifolia Nutt.) was reported as a new host for Phytophthora lateralis Tucker and Milbrath which is an aggressive root rot pathogen thought previously to be specific to Port-Orford-cedar. This study was designed to compare the pathogenicity of P. lateralis on the two hosts, and to...

Using local climate to explain temporal variation in rare plant populations

Creator:: Pfingsten, Ian A.
Abstract:: Increased temperatures due to anthropogenic-induced climate change may raise the threat of extinction for taxa with sessile life histories (e.g., plants) in the near future. Linking climate change models to demographic models may provide useful insights into the potential effects of environmental changes on rare plants, and therefore aid in...
