Mining Public Microbiome Datasets to Identify Specific Microbial Taxa Associated with Anxiety-Related Disorders

Creator:: Martin, Austin N.
Abstract:: Over the last ten years, clinical, pre-clinical and animal studies have shown associations between the microbiota and neurological functions. Recent work by the scientific community on the gut-microbiome-brain axis have revealed that gut dysbiosis and specific microbial taxa are associated with a myriad of neurological conditions, such as autism spectrum...

Evaluation of botanical diversity in Oregon vineyards

Creator:: Schonenberger, Patrik M.
Abstract:: Three different ground cover management strategies were compared at the OSU research vineyard near Alpine, Oregon. Botanical diversity was actively increased in two diverse treatments. Another treatment was botanically uniform and contained creeping bentgrass (Agrostis stolonifera). The composition of the vineyard floor vegetation and grapevine performance as affected by the...

Tumorigenic bacteria from blueberry stem galls are related to Rhizobium tumorigenes-like Agrobacteria found in Rhododendron crown gall in Germany

Creator:: Khalib, Nurul Ain
Abstract:: Blueberry stem galls in Pacific Northwest are often attributed to Agrobacterium tumefaciens. The disease also is associated with indole-3-acetic-acid (IAA) producing bacteria, as described on cranberry stem gall. Lack of studies makes it difficult to conclude whether these two types of bacteria could be the causal agent of stem gall...

The pen as mighty as the microscope : ethical issues in science and medical journalism

Creator:: Moser, Jennifer C.
Abstract:: Science is difficult for even its researchers to understand. Science journalists must understand scientific discoveries well enough to write clear, accurate explanations of scientific discoveries for laypeople. A sense of ethical judgment will help journalists ensure that their accounts are reliable and appropriate. Responsible science journalists will maintain a working...

Molecular characterization of specificity and activity of the transposable element IS801

Creator:: Richter, Grace Yukiko
Abstract:: 1S801 is a transposable element isolated from Pseudomonas syringae pathovar (pv.) phaseolicola, the causal agent of halo blight of bean. Fragments of the element are present in multiple copies on an indigenous plasmid, pMMC7105, of strain LR781, and have been implicated as sites of homologous recombination leading to imprecise excision...

Micropropagation of Pyrus rootstocks

Creator:: Yeo, Dennis
Abstract:: The availability of new pear rootstocks could be increased by development of an efficient micropropagation system. Many P. calleryana, P. betulifolia and P. communis rootstocks are resistant to many pear diseases and are graft compatible with leading cultivars. Explains of three potentially useful rootstock selections P. calleryana Decne 'OPR 157',...

Evolution of a streamlined cooperator in Pseudomonas aeruginosa quorum sensing

Creator:: Huie, Jessica L.
Abstract:: Social behavior leading to the production of common goods is prone to exploitation. One such behavior in Pseudomonas aeruginosa is quorum sensing (QS), by which the bacteria produce signals to regulate extracellular common goods. Exploitation comes in the form of cheaters which have a mutation in the central quorum sensing...

Comparative genomics of Vibrio and characterizing microbial communities at a shellfish hatchery

Creator:: Delgado, Hanna
Abstract:: Vibrio bacteria are commonly found in freshwater, marine, and estuarine environments. Members of this genus can exist in commensal relationships with marine animals or as planktonic bacteria, however, they are well known for their roles as pathogens towards humans and animals. In this dissertation, I investigated aspects of host-bacteria relationships...

Soil Solarization in Pacific Northwest Tree Seedling Nurseries: Effects on Soilborne Plant Pathogens, Soil Nutrients and the Soil Microbiome

Creator:: Weidman, Clara S.
Abstract:: Nursery and greenhouse products are economically important agricultural commodities for Oregon and Washington. Nursery crops including tree seedlings can be damaged or killed by soilborne plant pathogens, which can be challenging to manage because of their persistence in soil and limited options for control. Soil solarization is a pre-planting soil...

Diversity and Activity of Microbial Extracellular Peptidases in Soil

Creator:: Nguyen, Trang T. H.
Abstract:: Soil nitrogen exists largely as organic matter, including plant liter, dead animal matter, and microbial necromass. About 90% of soil organic nitrogen is proteinaceous material that is too large for plants and microorganisms to assimilate directly. Protein depolymerization therefore plays a critical role in mobilizing this organic source of nitrogen,...
