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...

Characterization of the Plasmids of the Pathogenic Plant Bacterium Erwinia amylovora in Washington and Oregon

Creator:: Carey, Alyssa B.
Abstract:: Erwinia amylovora is a plant pathogenic bacterium that causes the destructive disease fire blight of apple and pear. We examined the plasmid content of a collection of 305 isolates of E. amylovora from Washington and Oregon with PCR assays and RFLP. Nearly all isolates of E. amylovora carried plasmid pEA29,...

Induction of apple defense genes by Erwinia amylovora and biological control agents

Creator:: Bauer, Lisa M.
Abstract:: Fire blight is a serious disease of apple and pear trees caused by the bacterium, Erwinia amylovora. This bacterium harbors a pathogenesis mechanism known as the Hrp secretory operon which induces some resistance genes and suppresses other resistance genes in the host plant following invasion. While previous researchers analyzed expression...

Contribution of native plasmids to fitness of Pantoea vagans C9-1, a biological control agent for fire blight of apple and pear

Creator:: Klein, Jeannie M.
Abstract:: Pantoea vagans C9-1 (C9-1) is a biological control agent sprayed onto apple and pear trees during bloom for suppression of fire blight, a devastating bacterial disease caused by Erwinia amylovora. Prior bioinformatics studies of C9-1 focused on predicted phenotypes associated with the three native megaplasmids, pPag1, pPag2, and pPag3, and...

Analysis of boscalid resistance of isolates of Botrytis cinerea

Creator:: Villanueva, Brenda
Abstract:: Succinate dehydrogenase (Sdh) inhibitor fungicides, such as boscalid, are effective for the management of gray mold caused by the fungal pathogen Botrytis cinerea. Unfortunately, resistance to boscalid was common among isolates of the pathogen from small fruits grown in Oregon. Boscalid-resistance is commonly associated with mutations in Sdh, especially in...

Population structure and genetic variation in the Hawaiian Opakapaka (Pristipomoides filamentosus): Evidence of a genetic bottleneck in offspring of a captive broodstock

Creator:: Meltvedt, Ariana
Abstract:: The Hawaiian Archipelago is a biologically diverse environment with dynamic interactions between human and biological populations. Political, social, and scientific communities are placing importance on sustainable management of fisheries resources throughout the islands. Many economically important bottomfish in Hawaii have declined in population size due to anthropogenic and environmental pressures....

Predicting Protein-Protein Interactions in a Cnidarian Model System

Creator:: Gregory, Dylan B.
Abstract:: The symbiotic sea anemone Exaiptasia diaphana (Aiptasia) is a model organism used to better understand cnidarian-algal symbiosis and coral bleaching (dysbiosis). Many biological processes are hypothesized to be involved in coral dysbiosis, and the innate immunity is a key area of interest. Rab proteins are small proteins with GTPase domains,...

Contributions of photoautotrophy and heterotrophy to the carbon and nitrogen nutrition of Anthopleura elegantissima in three symbiotic states

Creator:: Hampton-Wonder, Kathryn Anne
Abstract:: The Pacific coast sea anemone Anthopleura elegantissima is an excellent model organism for the study of temperate symbiosis due to its unique relationship with two microalgal symbionts, Elliptochloris marina and Symbiodinium spp. In addition to hosting one or both of these symbionts, A. elegantissima can live aposymbiotically, allowing for the...

Is there a change in expression of apoptosis and autophagy genes in Aiptasia sp. after thermal stress?

Creator:: Flesher, Jessica L.
Abstract:: Corals form the foundation for coral reef ecosystems and contain symbiotic dinoflagellates which greatly contribute to reef primary productivity. Loss of dinoflagellates from animal (host) cells results in cnidarian bleaching which leads to decreased coral fitness, and reef deterioration. Elevated temperature, caused by global warming, is the primary environmental stressor...

Bread and Bread Making

Creator:: Ewing, Georgia Virginia
Abstract:: Bread is a kind of food made of the flour or meal of some species of grain, by kneading it (with the addition of a little salt, and sometimes sugar) into a dough, yeast being commonly added to cause fermentation or "lightness", and then baking it. The yeast causes alcoholic...
