Xanthomonas citri pv. malvacearum is a major pathogen of cotton, Gossypium hirsutum L.. In this study we report the complete genome of the X. citri pv. malvacearum strain MSCT1 assembled from long read DNA sequencing technology. The MSCT1 genome is the first X. citri pv. malvacearum genome with complete coding regions for X. citri pv. malvacearum transcriptional activator-like effectors. In add...
Many Xanthomonas bacteria use transcription activator-like effector (TALE) proteins to activate plant disease susceptibility (S) genes, and this activation contributes to disease. We recently reported that rice basal transcription factor IIA gamma subunit, OsTFIIAγ5, is hijacked by TALE-carrying Xanthomonas oryzae infecting the plants. However, whether TFIIAγs are also involved in TALE-carrying...
Antibacterial and antifungal activity was investigated for strains of Acidovorax spp., Burkholderia spp., Herbaspirillum rubrisubalbicans and Ralstonia solanacearum; strains representing 118 species and pathovars of Xanthomonas were also tested for phytotoxic capacity. Antibacterial activity was present in all Burkholderia spp. except B. andropogonis, in biovars II and III of R. solanacearum bu...
We have cloned a hrp gene cluster from Xanthomonas oryzae pv. oryzae. Bacteria with mutations in the hrp region have reduced growth in rice leaves and lose the ability to elicit a hypersensitive response (HR) on the appropriate resistant cultivars of rice and the nonhost plant tomato. A 12,165-bp portion of nucleotide sequence from the presumed left end and extending through the hrpB operon was...
We report the draft genome sequence of the Xanthomonas cassavae type strain CFBP 4642, the causal agent of bacterial necrosis on cassava plants. These data will allow the comparison of this nonvascular pathogen with the vascular pathogen Xanthomonas axonopodis pv. manihotis, both infecting the same host, which will facilitate the development of diagnostic tools.
We report here the high-quality draft genome sequences of two strains of Xanthomonas axonopodis pv. glycines, the causal agent of bacterial pustule on soybeans. Comparison of these genomes with those of phylogenetically closely related pathovars of Xanthomonas spp. will help to understand the mechanisms involved in host specificity and adaptation to host plants.
Tryptophan pyrrolase was studied in partially purified extracts of Xanthomonas pruni. The dialyzed enzyme required both heme and ascorbate for maximal activity. Other reducing agents were able to substitute for ascorbate. Protoporphyrin competed with heme for the enzyme, suggesting that the native enzyme is a hemoprotein. The enzyme exhibited sigmoid saturation kinetics. Reduced nicotinamide ad...
Xanthomonas is a large genus of bacteria that collectively cause disease on more than 300 plant species. The broad host range of the genus contrasts with stringent host and tissue specificity for individual species and pathovars. Whole-genome sequences of Xanthomonas campestris pv. raphani strain 756C and X. oryzae pv. oryzicola strain BLS256, pathogens that infect the mesophyll tissue of the l...
