The new CDS sir2x is involved in virulence in Xcc. (A) Domain organization of Sir2x as predicted by SMART (http://smart.embl-heidelberg.de/ webcite). (B) Genomic localization of sir2x and its flanking genes in the chromosome of Xcc strain 8004. (C) RT-PCR analysis of the XC_4281-sir2x operon. No genomic DNA contamination was indicated by normal PCR amplification using total RNAs as template. (D) In vitro virulence assay on Chinese cabbage. Δsir2x (sir2x) indicates the complemented deletion mutant defective in sir2x.
