The Ecology and Epidemiology of Xanthomonas hortorum pv. carotae in Central Oregon Carrot Seed Production Systems

Creator:: Baldino, Katelyn D.
Abstract:: Xanthomonas hortorum pv. carotae (Xhc) is an epiphytic, plant pathogenic bacterium that causes the disease bacterial blight of carrot (Daucus carota subsp. sativus). Infection with Xhc can result in blighting of leaves and umbels and reduce quality and yield of carrot seed crops. Carrot production in the United States approaches...

The phytoplankton and limnological characteristics of Lago Rupanco, Osorno, Chile

Creator:: Donoso, Teresa G.
Abstract:: Lago Rupanco is located in the central plain of Chile (Borgel, 1964) at 40° 50' S; 72° 30' W. It lies at 117 m above sea level, and corresponds to type 28c of Hutchinson's (1967) classification. Lago Rupanco is a warm, monomictic lake, with winter circulation and summer stratification. Physical,...

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 influence of soil fumigants and soil fungicides on some important soil-borne plant pathogens

Creator:: Liu, Marlene Mei-yu
Abstract:: Twelve chemicals (Busan 72, Chloropicrin, Dacthal, Dexon, Duter, EP 161, Lanstan, Methyl bromide, Phaltan, Vapam, Vidden D, Vorlex) were tested to determine their effect on populations of certain important soil-borne microorganisms including the onion pink root fungus Pyrenochaeta terrestris. The soil used was from a field in Malheur County, Oregon...

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...

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...

Characterization of strains of Scenedesmus resistant to the herbicide DCMU, (3-(3,4-dichlorophenyl)-1,1-dimethylurea)

Creator:: Smith, Muriel K.
Abstract:: Three DCMU resistant mutants of the green alga Scenedesmus obliquus D₃ are characterized. The mutants exhibit a ten fold greater resistance to DCMU than the wild type strain; this is comparable to the level of DCMU resistance detected in other DCMU resistant algae. In whole cell reactions, as well as...

Responses of algal populations to parasitism by Aphelidium chlorococcarum and chytrids in an Oregon sewage lagoon

Creator:: Woods, Wendy W.
Abstract:: The abundance of algal species and their parasites was monitored weekly for two years in a sewage lagoon at the Corvallis Airport, Oregon. During the cooler months, Euglena species were dominant followed by a Chlamydomonas assemblage in the spring and a predominantly Scenedesmus assemblage in the summer and fall. Parasites...
