Influence of a sudangrass green manure on microorganisms and early dying of potatoes in two soils

Creator:: Parks, Robin L.
Abstract:: Effect of a sudangrass green manure in two soil types on the activity, populations and community structure of soil microorganisms, populations of Verticillium dahliae in soil and on potato roots, and potato early dying, were evaluated in a field microplot experiment in the Columbia Basin. Potato cv. Russet Burbank was...

Revegetation in the 1914-1915 devastated area of Lassen Volcanic National Park

Creator:: Bailey, Warren Hutchinson, 1914-
Abstract:: At the time of the eruptions of Lassen Peak in 1914-1915, an area of vegetation along the east slope of the mountain approximately 1 1/4 miles wide and four miles long was destroyed. Except for a few surviving trees, all vegetation was destroyed. A study of the revegetation of this...

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,...

Patterns in the occupancy and abundance of the globally rare lichen Erioderma pedicellatum in Denali National Park and Preserve, Alaska

Creator:: Stehn, Sarah E., Nelson, Peter R., Roland, Carl A., and Jones, Jennifer R.
Abstract:: We investigated habitat attributes related to the occupancy of the globally rare and endangered epiphytic lichen, Erioderma pedicellatum, in a newly discovered (2009) population center in Denali National Park and Preserve (DNPP), Alaska. We measured forest, tree and epiphytic lichen community characteristics on eighty-five systematically selected plots in four study...

Some properties of ribonucleotide reductase in Rhizobium species

Creator:: Cowles, Joe Richard, 1941-
Abstract:: Ribonucleotide reductase from Rhizobium meliloti has been partially purified and characterized. The enzymatic reduction of ribonucleotides to deoxyribonucleotides is dependent upon B₁₂ coenzyme and dihydrolipoate. B₁₂ coenzyme was more effective than B₁₂ coenzyme analogues in the reductase reaction. The affinity of the R. meliloti reductase system for B₁₂ coenzyme was...
