Tn-seq identifies Ralstonia solanacearum genes required for tolerance of plant immunity induced by exogenous salicylic acid.

ABSTRACT: Ralstonia solanacearum, the causal agent of the devastating bacterial wilt disease, is of particular interest to the scientific community. The repertoire of type III effectors plays an important role in the evasion of plant immunity, but tolerance to plant immunity is also crucial for the survival and virulence of R. solanacearum. Nevertheless, a systematic study of R. solanacearum tolerance to plant immunity is lacking. In this study, we used exogenous salicylic acid (SA) to improve the immunity of tomato plants, followed by transposon insertion sequencing (Tn-seq) analysis and the identification of R. solanacearum genes associated with tolerance to plant immunity. Target gene deletion revealed that the lipopolysaccharide (LPS) production genes RS_RS02830, RS_RS03460, and RS_RS03465 are e
