Pathogenic bacteria in the genus Xanthomonas cause diseases on over 350 plant species, including cannabis (Cannabis sativa L.). Because of regulatory limitations, the biology of the Xanthomonas-cannabis pathosystem remains largely unexplored. To gain insight into the evolution of Xanthomonas strains pathogenic to cannabis, we sequenced the genomes of two geographically distinct Xanthomonas stra...

results: the lowest concentrations of nzvi that inhibited the visible growth (mic) of e. amylovora, x. oryzae, b. cereus and streptomyces spp. were 625, 550, 1250 and 1280 ppm, respectively. the minimum bactericidal concentration (mbc) for e. amylovora and x. oryzae were 10,000 and 5,000 ppm of nzvi, respectively. mbc was not observed for the gram positive bacteria. no bacteriostatic and bacter...

Bacterial blight and bacterial leaf streak are serious, economically damaging, diseases of rice caused by the bacteria Xanthomonas oryzae pv. oryzae and X. oryzae pv. oryzicola. Bacillus amyloliquefaciens FZB42 was shown to possess biocontrol activity against these Xanthomonas strains by producing the antibiotic compounds difficidin and bacilysin. Analyses using fluorescence, scanning electron ...

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....

XopD (Xanthomonas outer protein D), a type III secreted effector from Xanthomonas campestris pv. vesicatoria, is a desumoylating enzyme with strict specificity for its plant small ubiquitin-like modifier (SUMO) substrates. Based on SUMO sequence alignments and peptidase assays with various plant, yeast, and mammalian SUMOs, we identified residues in SUMO that contribute to XopD/SUMO recognition...

Bacterial leaf spot is a destructive disease in Rajasthan caused by Xanthomonas axonopodis pv. vesicatoria (Doidge) Dye. A field and market survey was conducted for the study of incidence location. Dry seed examination 103 samples chilli (Capsicum spp.) belonging to 16 districts that revealed 10–100% (XAV) on Tween-80 medium. Two naturally infected carrying 100% XAV were selected categorized in...

In this study, two halophilic bacterial strains isolated from saline habitats in Argentina grew in the presence of gas oil. They were identified as Halomonas spp. and Nesterenkonia sp. by 16S ribosomal RNA sequencing. Chemotaxis towards gas oil was observed in Halomonas spp. by using swimming assays.

UNLABELLED Members of the genus Xanthomonas are among the most important phytopathogens. A key feature of Xanthomonas pathogenesis is the translocation of type III secretion system (T3SS) effector proteins (T3SEs) into the plant target cells via a T3SS. Several T3SEs and a murein lytic transglycosylase gene (mlt, required for citrus canker symptoms) are found associated with three transposition...
