Gene-for-gene interactions of five cloned avirulence genes from Xanthomonas campestris pv. malvacearum with specific resistance genes in cotton.
A total DNA clone bank of a strain of Xanthomonas campestris pv. malvacearum (Xcm) was constructed in the cosmid vector pSa747 and transfected into Escherichia coli. The Xcm strain carries at least nine identifiable avirulence (A) genes. Clones in E. coli were mated individually into a recombination-proficient Xcm isolate carrying no known A genes. Screening was for incompatibility on congenic ...
متن کاملThe genome of the cotton bacterial blight pathogen Xanthomonas citri pv. malvacearum strain MSCT1
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...
متن کاملBiological role of xanthomonadin pigments in Xanthomonas campestris pv. campestris.
Previous studies have indicated that the yellow pigments (xanthomonadins) produced by phytopathogenic Xanthomonas bacteria are unimportant during pathogenesis but may be important for protection against photobiological damage. We used a Xanthomonas campestris pv. campestris parent strain, single-site transposon insertion mutant strains, and chromosomally restored mutant strains to define the bi...
متن کاملGenome Sequence of Xanthomonas campestris pv. campestris Strain Xca5
An annotated high-quality draft genome sequence for Xanthomonas campestris pv. campestris race 1 strain Xca5 (originally described as X. campestris pv. armoraciae), the causal agent of black rot on Brassicaceae plants, has been determined. This genome sequence is a valuable resource for comparative genomics within the campestris pathovar.
متن کاملSalicylic acid mediated by the oxidative burst is a key molecule in local and systemic responses of cotton challenged by an avirulent race of Xanthomonas campestris pv malvacearum.
We analyzed the production of reactive oxygen species, the accumulation of salicylic acid (SA), and peroxidase activity during the incompatible interaction between cotyledons of the cotton (Gossypium hirsutum) cv Reba B50/Xanthomonas campestris pv malvacearum (Xcm) race 18. SA was detected in petioles of cotyledons 6 h after infection and 24 h post inoculation in cotyledons and untreated leaves...
