RESUMO
hrpG is a key regulatory gene for transcriptional activation of pathogenicity genes (hrp) of Xanthomonas campestris pv. vesicatoria. We identified three mutations in hrpG which render hrp gene expression constitutive in normally suppressing medium. The mutations in hrpG result in novel amino acid substitutions compared to mutations in related proteins, such as OmpR. In addition, mutated hrpG enhances the timing and intensity of plant reactions in infection assays.
