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...

Endometrial Inflammatory Cytokine Expression in Postpartum Beef Heifers Following Platelet Rich Plasma Treatment

Creator:: Perez, Victor O.
Abstract:: Background: Uterine inflammation (e.g., endometritis) causes negative economic effects in the beef industry by reducing reproductive performance. Current treatments for endometritis in beef cattle involve hormones and antibiotics, which can be expensive and are often ineffective. The endometrial immune response regulates the release of cytokines and chemokines in response to...

Survey of rhizosphere associated entomopathogenic fungi on small fruits and Christmas trees in the Willamette Valley, OR

Creator:: Fisher, Joanna J.
Abstract:: The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana are commercially available as microbial control agents for the black vine weevil, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae), the key root-feeding insect pest in Pacific Northwest small fruits and ornamentals. Understanding habitat selection is critical to improve the efficacy, persistence and cost of...

Geographic variation in the seed mycobiome of Coastal Douglas-fir (Pseudotsuga menziesii var. menziesii)

Creator:: Bergmann, Gillian E.
Abstract:: Seeds are an essential component of plant life histories, and seed endophytes have the potential to influence germination, seedling establishment and development. That said, seed endophytes are a relatively new area of study, both in the factors that influence which taxa are present and how these microbes alter plant function....

Toxicity and Mutagenicity of Polycyclic Aromatic Hydrocarbons in Contaminated Soils using Mammalian In Vitro Assay

Creator:: Luker, George W.
Abstract:: There exists a growing need to establish a better in vitro model for evaluating PAH toxicity and carcinogenicity and to improve assessments of risk to human health, especially to the complex mixtures that exist in the environment. Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental contaminants due to the incomplete combustion...

Biochar as a cover for dairy manure lagoons: reducing odor and gas emissions while capturing nutrients

Creator:: Dougherty, Brian W.
Abstract:: Liquid manure lagoons are known to be sources of odor and environmentally damaging gas emissions. Land application of the manure slurry after storage can lead to detrimental nutrient runoff and leaching. Floating lagoon covers (biocovers) are one option for reducing emissions, but to date they have only been used to...

Pathogenicity to western larch (Larix occidentalis) of two fungi, Ophiostoma oseudotsugae and Leptoaraghium abietinum, associated with the douglas-fir beetle (Coleoptera: Scolytidae) in Eastern Oregon, U.S.A.

Creator:: Neal, Tiffany A. and Ross, Darrell W.
Abstract:: Pole-sized, live western larch Larix occidentalis Nutt.) were inoculated with Ophiostoma pseudotsugae(Rumb.) von Arx or Leptographium abietinum (Peck) Wingf., two blue stain fungi associated with the Douglas-fir beetle (Dendroctonous pseudotsugae Hopkins), to assess their pathogenicity. Inoculation with O. pseudotsugae resulted in a significantly greater percentage of necrotic phloem compared to...

Systematically evaluating the developmental toxicity of nanomaterials using the zebrafish model

Creator:: Edwards, Sabrina R.
Abstract:: As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...

Is Advection Important? An Examination of the Advective Dynamics of Sensible Heat and Their Influence onSubcanopy Carbon Fluxes in Heterogeneous Terrain

Creator:: Carrigg, Sean Stephen
Abstract:: Abstract Understanding small-scale bio-atmospheric interactions is becoming increasingly important as the global climate continues to change at breakneck speed. A theoretical model of the sensible heat budget of a forest is developed combining conservation equations and concepts from fluid dynamics. Budget components are computationally evaluated using micrometeorological data taken during...
