Characterization of alginate lyase from Pseudomonas syringae pv. syringae.
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 at 42 degrees C in the presence of 0.2 M NaCl. In substrate specificity studies, AlgL from P. syringae showed a preference for deacetylated polymannuronic acid. Sequence a...
متن کاملDraft Genome Sequence of Pseudomonas syringae pv. syringae ALF3 Isolated from Alfalfa
We report here the annotated draft genome sequence of Pseudomonas syringae pv. syringae strain ALF3, isolated in Wyoming. A comparison of this genome sequence with those of closely related strains of P. syringae adapted to other hosts will facilitate research into interactions between this pathogen and alfalfa.
متن کاملHigh-Quality Draft Genome Sequence of Pseudomonas syringae pv. Syringae Strain SM, Isolated from Wheat
Pseudomonas syringae is one of the most widespread plant pathogens that can cause significant damage to crop plantations. Here, we announce a noncontiguous finished genome sequence of Pseudomonas syringae pv. syringae strain SM, isolated from hexaploid wheat. The genome sequence revealed the smallest described complement of type III effectors.
متن کاملRegulation of alginate biosynthesis in Pseudomonas syringae pv. syringae.
Both Pseudomonas aeruginosa and the phytopathogen P. syringae produce the exopolysaccharide alginate. However, the environmental signals that trigger alginate gene expression in P. syringae are different from those in P. aeruginosa with copper being a major signal in P. syringae. In P. aeruginosa, the alternate sigma factor encoded by algT (sigma22) and the response regulator AlgR1 are required...
متن کاملPCR Detection of Cyclic Lipodepsinonapeptide-Producing Pseudomonas syringae pv. syringae and Similarity of Strains.
Many strains of Pseudomonas syringae pv. syringae produce one of four classes of small cyclic lipodepsinonapeptides: syringomycins, syringostatins, syringotoxins, or pseudomycins. These metabolites are phytotoxic and growth inhibitory against a broad spectrum of fungi. Their production is dependent upon the expression of conserved biosynthesis and export genes syrB and syrD, respectively. PCR a...
