Construction and physiological analysis of a Xanthomonas oryzae pv. oryzae recA mutant.


A Xoo recA insertion inactivation mutant was constructed. The mutant, lacking RecA, showed increased sensitivity towards mutagen killing. This phenotype could be complemented by a cloned, functional recA. Unlike other bacteria, both the recA mutant and the parental strain had similar level of resistance to H2O2 killing and peroxide-induced mutagenesis.
