xanthan gum is a microbial polysaccharide of great commercial importance as it has unusual rheological properties in solution and consequent range of applications. in this study, a series of mutants were isolated from xanthomonas campestris ptcc 1473 by ethyl methanesulfonate mutagenesis. the polysaccharide yield of one mutant, xc1473e2, was 30% better than that of the parent strain. it also sh...
The present study is to concentrate on the synergistic bactericidal effect of silver nanoparticles and ciproflaxacin against Pseudomonas solanocearum, Pseudomonas syringae, Xanthomonas malvacearum and Xanthomonas campestris. Silver nanoparticles were prepared in 0.1mM, 0.2 mM and 0.3 mM by Spirulina platensis. It exhibited anti microbial activity against all phytopathogens with varying degrees....
We determined the draft genome sequence of the Pseudomonas syringae pv. tabaci strain yuexi-1. It was isolated from tobacco sample of yuexi-1, Sichuan province, China, by our laboratory. The genome contains 6,232,497 bp and has a G+C content of 58.2 mol%.
In Xanthomonas campestris pv. campestris, SoxR likely functions as a sensor of redox-cycling drugs and as a transcriptional regulator. Oxidized SoxR binds directly to its target site and activates the expression of xcc0300, a gene that has protective roles against the toxicity of redox-cycling compounds. In addition, SoxR acts as a noninducible repressor of its own expression. X. campestris pv....
SUMMARY In Gram-negative bacteria a typical quorum sensing (QS) system usually involves the production and response to acylated homoserine lactones (AHLs). An AHL QS system is most commonly mediated by a LuxI family AHL synthase and a LuxR family AHL response regulator. This study reports for the first time the presence of a LuxR family-type regulator in Xanthomonas oryzae pv. oryzae (Xoo), whi...

Xanthomonas campestris pv. campestris is the causal agent of black rot on Brassicaceae. The draft genome sequences of strains CFBP 1869 and CFBP 5817 have been determined and are the first ones corresponding to race 1 and race 4 strains, which have a predominant agronomic and economic impact on cabbage cultures worldwide.
Xanthomonas citri pv. vignicola strains cause bacterial blight of the legume crop cowpea. We report whole-genome sequences of three X. citri pv. vignicola strains obtained using PacBio single-molecule real-time sequencing. Such genomic data provide new information on pathogenicity factors, such as transcription activator-like effectors.
