Research Abstract

Ralstonia solanacearum OE1-1 strain contains more than 70 effector genes. We deleted each effector gene, and the deletion mutant showed the same virulence on eggplant as the wild type, except the rsc0245 mutant. We also deleted effector family genes, each of 7 gala, 6 SKWP, and 3 HLK, and all of 16 genes. All the deletion mutants still retained virulence, while they showed the difference phenotype on different hosts, tomato and tobacco.
