Risk of Exposure to Eastern Equine Encephalomyelitis Virus Increases with the Density of Northern Cardinals

Creator:: Estep, Laura K., McClure, Christopher J. W., Vander Kelen, Patrick, Burkett-Cadena, Nathan D., Sickerman, Stephen, Hernandez, José, Jinright, Joseph, Hunt, Brenda, Lusk, John, Hoover, Victor, Armstrong, Keith, Stark, Lillian M., Hill, Geoffrey E., and Unnasch, Thomas R.
Abstract:: For a variety of infectious diseases, the richness of the community of potential host species has emerged as an important factor in pathogen transmission, whereby a higher richness of host species is associated with a lowered disease risk. The proposed mechanism driving this pattern is an increased likelihood in species-rich...

D-Lactate metabolism and the obligate requirement for CO2 during growth on nitrite by the facultative lithoautotroph Nitrobacter hamburgensis

Creator:: Starkenburg, Shawn R., Arp, Daniel J., and Bottomley, Peter J.
Abstract:: Nitrobacter hamburgensis X14 is a facultative lithoautotroph that conserves energy from the oxidation of nitrite (NO 2 ) and fixes carbon dioxide (CO2) as its sole source of carbon. The availability of the N. hamburgensis X14 genome sequence initiated a re-examination of its mixotrophic and organotrophic potential, as genes encoding...

Candidate Genes Associated with Blister Rust Resistance in Whitebark Pine (Pinus albicaulis) Revealed through de novo Transcriptome Assembly and Differential Gene Expression Analysis

Creator:: Bair, Zolton J.
Abstract:: Whitebark pine (Pinus albicaulis) is an iconic North American high-elevation tree species currently threatened by climate change, mountain pine beetle, and white pine blister rust (WPBR), a lethal disease caused by the non-native fungal pathogen Cronartium ribicola. In collaboration with the USDA Forest Service Dorena Genetic Resource Center, germplasm was...

Light-induced absorbance changes and partial reactions of photosynthesis in mutants of Scenedesmus obliquus, strain D₃

Creator:: Pratt, Lee Herbert
Abstract:: Partial reactions of photosynthesis were examined in the wild type strain and six photosynthetic mutants (8, 11, 26, 40, 50, a') of Scenedesmus obliquus, strain D₃. A reproducible procedure for the isolation of active chloroplast fragments from Scenedesmus was developed. Several chloroplast reactions were examined, as well as two in...

The glutamine synthetases in soybean root nodules and free-living Rhizobium japonicum

Creator:: Guevara, Juan Garcia
Abstract:: Glutamine synthetase activity is present in both the cytosol and bacteroid fractions of soybean root nodules. Total activity measurements indicate that at least 90% of the activity in nodules is located in the cytosol. Results reported by McParland, et al. (29), showed that many properties of glutamine synthetase from nodule...

A revision of Juncus subgenus genuini (Juncaceae) in the Pacific states

Creator:: Lint, Harold LeRoy
Abstract:: A study was made of the subgenus Genuini of the genus Juncus in the Pacific States, California, Oregon and Washington. Extensive morphological comparisons, geographical distributions, habitat differences and observations of apparent presence or absence of natural hybrids provided the major data sources. Cytological studies were made, but were inconclusive. Eleven...

Viability and infective potential of Phytophthora pini zoospores in a recirculating irrigation system

Creator:: Shay, Sarah D.
Abstract:: Phytophthora pini Leonian, recently re-established from P. citricola I, is a pathogen with a wide range of forest and nursery hosts. It causes foliar infections in horticultural nurseries in Oregon, where recirculating irrigation systems are common. Increased use of recirculating irrigation systems may contribute to disease caused by waterborne plant...

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...

Epiphytic yeasts isolated from apple leaves to control of gray and blue mold fruit rots of apple

Creator:: Falconi, Cesar E.
Abstract:: Eight phylloplane yeasts were isolated from backyard apple trees in Corvallis, OR. Yeast isolates were classified to genus or species level. All isolates were tested in vitro for antagonistic activity against the postharvest pathogens Botrytis cinerea and Penicillium expansum. Of these isolates, Aureobasidium pullulans, Sporobolomyces roseus Rhodotorula sp., consistently reduced...
