Advances on the Molecular Mechanism of the Interaction between Ralstonia solanacearum and Hosts

Ralstonia solanacearum is an important model phytopathogenic bacterium that causes bacterial wilt disease on many plant species and leads to serious eco-nomic losses. The interactions between R. solanacearum and host plants have be-come a model system for the study of plants and pathogens interactions. This pa-per reviews the advances on the molecular mechanisms between R. solanacearum and hosts interaction including the formation of plant innate immunity, the suppres-sion of plant innate immunity by this pathogen and the activation of effector-trig-gered immunity. Furthermore, we made a prospect on how to utilize the interaction mechanism between R. solanacearum and hosts to control the disease.
