XCC2366, a gene encoding a putative TetR family transcriptional regulator, is required for acriflavin resistance and virulence of Xanthomonas campestris pv. campestris
Current Microbiology 74 (12), 1373-1381
Abstract: Xanthomonas campestris pv. campestris (Xcc) is the phytopathogen that causes black rot disease in cruciferous plants. The XCC2366 gene product is annotated as a protein belonging to the TetR family of transcriptional regulators. In this study, we evaluated the function and expression of the XCC2366 gene. Mutational analysis demonstrated that XCC2366 is involved in the resistance to acriflavin and is necessary for virulence in Xcc. In addition, the XCC2366 transcription initiation site was mapped at nucleotide A, 63 nucleotide upstream of the XCC2366 translation start codon. Furthermore, transcriptional analysis revealed that the expression of XCC2366 is induced in the presence of acriflavin. Reporter assay also showed that XCC2366 regulates its own expression under acriflavin-supplemented condition. To the best of our knowledge, acriflavin resistance-related gene in the crucifer pathogen Xcc was characterized for the first time.
