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...

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...

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...

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...

pA506, a Conjugative Plasmid of the Plant Epiphyte Pseudomonas fluorescens A506

Creator:: Stockwell, Virginia O., Davis, Edward W., II, Carey, Alyssa, Shaffer, Brenda T., Mavrodi, Dmitri V., Hassan, Karl A., Hockett, Kevin, Thomashow, Linda S., Paulsen, Ian T., and Lopera, Joyce E.
Abstract:: Conjugative plasmids are known to facilitate the acquisition and dispersal of genes contributing to the fitness of Pseudomonas spp. Here, we report the characterization of pA506, the 57-kb conjugative plasmid of Pseudomonas fluorescens A506, a plant epiphyte used in the United States for the biological control of fire blight disease...

Abstract:: We provide here a comparative genome analysis of ten strains within the Pseudomonas fluorescens group including seven new genomic sequences. These strains exhibit a diverse spectrum of traits involved in biological control and other multitrophic interactions with plants, microbes, and insects. Multilocus sequence analysis placed the strains in three sub-clades,...

Addressing the relationship between Pseudoperonospora cubensis and P. humuli using phylogenetic analyses and host specificity assays

Creator:: Mitchell, Melanie N.
Abstract:: The two most economically important plant pathogens in the Pseudoperonospora (Peronosporaceae) genus are P. cubensis, causal agent of cucurbit downy mildew, and P. humuli, causal agent of hop downy mildew. These organisms have been shown to be very closely related phylogenetically and morphologically. In 2005, researchers in Korea proposed that...
