Dissection of Innate Immunity in Tomato and Tolerance to Bacterial Wilt in Solanaceae species
… of effectors of the soil borne pathogen Ralstonia solanacearum, a causative agent of bacterial wilt. Four effectors were found to trigger plant defenses in some of the lines. This is the first step in cloning the genes coding for the responsible resistance proteins. These genes may be …
