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...

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...

Development and Application of Tools for Genetic Analysis of Clonal Populations

Creator:: Kamvar, Zhian N.
Abstract:: Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...

Within-population genetic structure differs between two sympatric sister-species of ectomycorrhizal fungi, Rhizopogon vinicolor and R. vesiculosus

Creator:: Dunham, Susie M., Mujic, Alija Bajro, Spatafora, Joseph W., and Kretzer, Annette M.
Abstract:: Using spatial autocorrelation analysis, we examined the within-population genetic structure of Rhizopogon vinicolor and R. vesiculosus, two hypogeous ectomycorrhizal (EM) species that are sympatric sister taxa known to differ in their clonal structure. We collected 121 sporocarps and 482 tuberculate EM of both species from a 20 ha forest stand...

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,...

A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...

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...

New Tools for Managing Erysiphe necator: Rapid Sampling Approaches and an Exploration of Grower Opinions and Perspectives towards Collective Action and Information Transfer

Creator:: Lowder, Sarah R.
Abstract:: The scale of pest and disease dispersal is often larger than the scale of individual farms. Therefore, an individual grower’s response to pests and diseases can affect and is affected by their surrounding growing region. Individual growers are also not isolated, and engage in various forms of information gathering, sharing,...

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...
