<i>Xanthomonas citri</i> subsp. <i>citri</i> requires a genus-specific outer membrane protein and TolB to coordinate cell membrane integrity and virulence.

ABSTRACT: Xanthomonas citri subsp. citri (Xcc) possesses a Xanthomonas-specific outer membrane protein XAC1347 (OMP_Xan) that exerts a role in the expression of the type III secretion system for pathogenicity. In this study, we reported that OMP_Xan was required for salt stress tolerance and cell membrane integrity, as well as the expression of the gum genes for the production of extracellular polysaccharides. Pull-down and yeast two-hybrid assays revealed that OMP_Xan interacts with TolB, a substrate of the Tol/Pal membrane protein system. The deletion of tolB resulted in similar phenotypic alterations as the OMP_Xan mutant in salt stress tolerance, cell membrane integr
