Three amino acid residues are required for the recognition of Ralstonia solanacearum RipTPS in Nicotiana tabacum.

ABSTRACT: Ralstonia solanacearum causes devastating diseases in a wide range of economically important crops. It secretes a large number of virulence factors, also known as effectors, to promote its infection, and some of them are recognized when the host plant contains corresponding resistance genes. In this study we showed that a type III effector RipTPS from the avirulent R. solanacearum strain GMI1000 (RipTPS_G) specifically induced cell death in Nicotiana tabacum, but not in Nicotiana benthamiana, whereas the RipTPS homolog in the virulent strain CQPS-1 (RipTPS_C) induced cell death in neither N. tabacum nor N. benthamiana. These results indicated that RipTPS_G is recognized in N. tabacum. Expression of RipTPS_G<
