Influence of site, soil, and inoculum density on dwarf bunt (Tilletia controversa Kühn) of winter wheat

Creator:: Clark, Deborah Ann, 1954-
Abstract:: Field microplot studies conducted over two seasons (1982-1984) evaluated the influence of four physically and chemically diverse soils collected from Pacific Northwest wheat fields on the incidence of dwarf bunt of winter wheat caused by Tilletia controversa Kuhn. These soils were placed at Flora and Pendleton, Oregon to determine the...

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...

Microbial analysis of coniferous forest and nursery soils : effects of ectomycorrhizae, volatiles, and humic-rich organic substrates

Creator:: Schisler, David Albert
Abstract:: Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...

Serpentine and non-serpentine edaphic ecology and the recovery of Lomatium cookii (Apiaceae), an endangered endemic of southwest Oregon

Creator:: Silvernail, Ian S.
Abstract:: The role of unusual geologies in plant distribution and form is well-known. Serpentine (ultramafic) soils exert a particularly strong influence on plants, as evidenced by a high level of endemism and the morphological and physiological traits displayed in adaptation to the extraordinary chemistry of these substrates. Adaptation may lead to...

Thauera butanivorans sp. nov., a C₂–C₉ alkane-oxidizing bacterium previously referred to as ‘Pseudomonas butanovora’

Creator:: Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: The placement of ‘Pseudomonas butanovora’ in the genus Thauera was proposed previously, based on 16S rRNA gene sequence analysis, upon further studies of taxonomical characteristics. In this study, physiological characteristics and DNA–DNA reassociation data are presented and the transfer of ‘P. butanovora’ to the genus Thauera is proposed. The original...

Phytosanitation of Douglas-fir (Pseudotsuga menziesii) logs to mitigate the risk of artificially disseminating Phytophthora ramorum within the global trade of timber

Creator:: Hulbert, Joseph M.
Abstract:: Phytophthora ramorum is a plant pathogen that was accidentally introduced to the United States. This invasive microorganism has killed over a million trees in California and Oregon, and continues to spread to new areas. Diseased areas have been nationally quarantined to prevent further spread and more than ninety countries include...

Kinetic characterization of the soluble butane monooxygenase from Thauera butanivorans, formerly ‘Pseudomonas butanovora’

Creator:: Cooley, Richard B., Dubbels, Bradley L., Sayavedra-Soto, Luis A., Bottomley, Peter J., and Arp, Daniel J.
Abstract:: Soluble butane monooxygenase (sBMO), a three-component di-iron monooxygenase complex expressed by the C2–C9 alkane-utilizing bacterium Thauera butanivorans, was kinetically characterized by measuring substrate specificities for C1–C5 alkanes and product inhibition profiles. sBMO has high sequence homology with soluble methane monooxygenase (sMMO) and shares a similar substrate range, including gaseous and...

Influence of atmospheric humidity on sporulation of Sphaerotheca pannosa (Wallr.) Lev. var. rosae Wor.

Creator:: Hural, Kirsten
Abstract:: The influence of atmospheric humidity on three aspects of sporulation of Sphaerotheca pannosa (Wallr.) Lev. var. rosae Wor., which causes rose powdery mildew, was studied on leaf disks of susceptible Rosa cultivar Samantha. To study conidiophore production, leaf disks were inoculated on the adaxial (upper) surface with conidia of S....
