	Abstract

Growth of Ralstonia solanacearum strain OE1-1 (OE1-1) in roots after invasion is required for its virulence. The Arg740Cys substitution in 70 of OE1-1 resulted in its loss of in planta growth and virulence. The negative dominance of mutant 70 over the wild-type protein suggested that the amino acid substitution may affect in planta growth of OE1-1, leading to lacking its virulence.
