Similarity between copper resistance genes from Xanthomonas campestris and Pseudomonas syringae
(American Society for Microbiology, 1993-05)
Plasmid-borne copper resistance genes from copper-resistant strains of Xanthomonas campestris pv. vesicatoria from California, Florida, and Oklahoma shared structural similarities. A strain of X. campestris pv. campestris ...
Growth phase and temperature influence promoter activity, transcript abundance, and protein stability during biosynthesis of the Pseudomonas syringae phytotoxin coronatine
(American Society for Microbiology, 1998-03)
The plant-pathogenic bacterium Pseudomonas syringae pv. glycinea PG4180.N9 synthesizes high levels of the polyketide phytotoxin coronatine (COR) at 18°C, whereas no detectable toxin is produced at 28°C. Previously, we ...
Characterization of alginate lyase from Pseudomonas syringae pv. Syringae
(American Society for Microbiology, 2000-11)
The gene encoding alginate lyase (algL) in Pseudomonas syringae pv. syringae was cloned, sequenced, and overexpressed in Escherichia coli. Alginate lyase activity was optimal when the pH was 7.0 and when assays were conducted ...
Characterization of CorR, a transcriptional activator which is required for biosynthesis of the phytotoxin coronatine
(American Society for Microbiology, 1998-12)
Coronatine (COR) is a plasmid-encoded phytotoxin synthesized by several pathovars of phytopathogenic Pseudomonas syringae. The COR biosynthetic gene cluster in P. syringae pv. glycinea PG4180 is encoded by a 32-kb region ...
Identification and relatedness of coronatine-producing Pseudomonas syringae pathovars by PCR analysis and sequence determination of the amplification products
(American Society for Microbiology, 1994-08)
Production of the chlorosis-inducing phytotoxin coronatine in the Pseudomonas syringae pathovars atropurpurea, glycinea, maculicola, morsprunorum, and tomato has been previously reported. DNA hybridization studies previously ...
Genetic and plasmid diversity within natural populations of Pseudomonas syringae with various exposures to copper and streptomycin bactericides
(American Society for Microbiology, 1994-12)
We examined the genetic and plasmid diversity within natural populations of Pseudomonas syringae isolated from three ornamental pear nurseries in eastern Oklahoma. The bactericide spray regimen differed at each nursery; ...
AlgT (sigma^22) controls alginate production and tolerance to environmental stress in Pseudomonas syringae
(American Society for Microbiology, 1999-12)
Pseudomonas aeruginosa and the phytopathogen P. syringae produce the exopolysaccharide alginate, which is a copolymer of D-mannuronic and L-guluronic acids. One of the key regulatory genes controlling alginate biosynthesis ...
Characterization of the alginate biosynthetic gene cluster in Pseudomonas syringae pv. syringae
(American Society for Microbiology, 1997-07)
Alginate, a copolymer of D-mannuronic acid and L-guluronic acid, is produced by a variety of pseudomonads, including Pseudomonas syringae. Alginate biosynthesis has been most extensively studied in P. aeruginosa, and a ...
DNA probes for detection of copper resistance genes in Xanthomonas campestris pv. Vesicatoria
(American Society for Microbiology, 1991-08)
The copper resistance (Cu^r) genes encoded on pXV1OA, a 190-kb plasmid in Xanthomonas campestris pv. vesicatoria XV10, were isolated on a 44-kb cosmid clone designated pCuRl. TnS mutagenesis of pCuRl indicated that a 4.0-kb ...
Expression of the strA-strB streptomycin resistance genes in Pseudomonas syringae and Xanthomonas campestris and characterization of IS6100 in X. campestris
(American Society for Microbiology, 1995-08)
Expression of the strA-strB streptomycin resistance (Sm^r) genes was examined in Pseudomonas syringae pv. syringae and Xanthomonas campestris pv. vesicatoria. The strA-strB genes in P. syringae and X. campestris were encoded ...
