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...

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...

Use of antibiotics in plant agriculture

Creator:: Stockwell, V. O. and Duffy, B.
Abstract:: Antibiotics are essential for control of bacterial diseases of plants, especially fire blight of pear and apple and bacterial spot of peach. Streptomycin is used in several countries; the use of oxytetracycline, oxolinic acid and gentamicin is limited to only a few countries. Springtime antibiotic sprays suppress pathogen growth on...

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...

Effect of iron on biological control of fire blight by Pseudomonas fluorescens A506

Creator:: Temple, Todd N.
Abstract:: Competitive exclusion has been the mechanism hypothesized to account for the biological control of fire blight disease of pear and apple by the bacterium Pseudomonas fluorescens A506 (A506). Recent laboratory assays demonstrated, however, that A506 produces an antibiotic that is toxic to the fire blight pathogen, Erwinia amylovora, when cultured...

Enhancement of thiamin in plants by metabolic engineering

Creator:: Dong, Wei, Stockwell, Virginia O., and Goyer, Aymeric
Abstract:: Thiamin is an essential nutrient in the human diet. Severe thiamin deficiency leads to beriberi, a lethal disease which is common in developing countries. Thiamin biofortification of staple food crops is a possible strategy to alleviate thiamin deficiency-related diseases. In plants, thiamin plays a role in the response to abiotic...

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...

Phytochemical profiles and antioxidant activity of some grape accessions (Vitis spp.) native to Eastern Anatolia of Turkey

Creator:: Eyduran, Sadiye Peral, Akin, Meleksen, Ercisli, Sezai, and Eyduran, Ecevit
Abstract:: Phytochemical profiles and antioxidant activity of four historical grape accessions (‘Kuzu Kuyrugu’, ‘Miskali’, ‘Erkek Miskali’, and ‘Kirmizi Kismis’) grown in Igdir province located in Eastern Anatolia Region of Turkey were examined. The amount of vitamin C, organic acids (citric acid, tartaric acid, malic acid, succinic acid and fumaric acid), sugars...
