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...

Characterization and Cultivar Susceptibility Assessment of Bacterial Blight in Hazelnut Caused by Xanthomonas arboricola pv. corylina

Creator:: Webber, John B., III
Abstract:: Bacterial blight (Xanthomonas arboricola pv. corylina) (Xac) of hazelnut (Corylus avellana L.) was described first in Oregon in 1915 and is now recognized as a damaging disease of young hazelnut trees worldwide. Stressed hazelnut trees in conditions such as planting on marginal sites, and trees between 1 and 4-years-old are...

Improving initiation and mineral nutrition for hazelnut (Corylus avellana) micropropagation

Creator:: Hand, Charles R.
Abstract:: Corylus avellana L. is a global commodity and a valuable crop for the U.S. Pacific Northwest. A tremendous amount of work has been put into the development of healthy disease free, high yielding and tasty hazelnuts for the in-shell and confectionary markets. Clonal propagation is required to provide nursery trees...

Evaluation of the colonization and biofilm production by Burkholderia pyroccinia FP62 on geranium leaves

Creator:: Wallace, Patricia K.
Abstract:: The leaf surface is a stark environment for bacterial colonists with limited availability of nutrients, water and protected niches. Despite these limitations, a plethora of bacteria appear to have adapted ways to survive and flourish on leaf surfaces. One mechanism of survival is the formation of biofilms. Biofilms are a...

Phenotyping Ornamental Plants: Case Studies in Fruit Quality Attributes from Vaccinium ovatum and Disease Resistance of Cotoneaster spp.

Creator:: Neill, Kristin E.
Abstract:: Landscape plants are highly diverse and nursery producers often grow thousands of taxa to satisfy the varied needs and aesthetic tastes of consumers. Related to this diversity, ornamental plant breeders must be nimble and diverse in their approach. Two seemingly disparate studies were conducted to investigate improving ornamental shrubs –...

Genome sizing and fire blight resistance screening in Cotoneaster

Creator:: Rothleutner, Joseph J.
Abstract:: Cotoneaster is an ornamental shrub valued for showy flowers, berries and architecture as well as the ability tolerate adverse conditions under which other taxa fail. Cotoneaster is a highly diverse genus of over 400 species, of which few are available in the US nursery trade. Some species commercially available have...

TonB-dependent outer-membrane proteins of Pseudomonas fluorescens : diverse and redundant roles in iron acquisition

Creator:: Hartney, Sierra L.
Abstract:: Pseudomonas is a diverse genus of Gram-negative bacteria that includes pathogens of plants, insects, and humans as well as environmental strains with no known pathogenicity. Pseudomonas fluorescens itself encompasses a heterologous group of bacteria that are prevalent in soil and on foliar and root surfaces of plants. Some strains of...
