Analyses of Ralstonia solanacearum type III effector proteins that can suppress plant disease resistance responses mediated by vesicular trafficking

Ralstonia solanacearum, the causal agent of bacterial wilt on solanaceous plants, injects virulence effector proteins into host plant cells via a type III secretion system to cause disease. In this study, we found that R. solanacearum possesses over 70 type III effectors. We constructed a series of recombinant plants and yeasts that express individual effector protein and identified effector proteins that show an ability to suppress vesicular trafficking in eukaryote cells.
