| Transgenic rice plants expressing XOO1488 (Xoo1488-OX) were generated and inoculated with the T3SS-deficient //hrpX// mutant of //Xoo//, which is incapable of type III effector delivery. The //Xoo hrpX// mutant did not cause lesions in wild-type plant, presumably because of strong induction of PTI. In contrast, Xoo1488-OX plants had severe disease symptoms following infection with the //Xoo hrpX// mutant. Bacterial populations of the //Xoo hrpX// mutant in Xoo1488-OX leaves were higher than in wild-type plants. The growth of wild-type isolate //Xoo// MAFF311018 in Xoo1488-OX plants also increased significantly over its growth in wild-type plants. Thus, it is likely that XopY inhibits PTI induced by infection of //Xoo hrpX// mutant. However, it was noted that XopY knockout strain did not exhibit any defect in virulence (Yamaguchi //et al//., 2013a). XopY was also shown to inhibit chitin-induced expression of defense-related genes (Yamaguchi //et al.//, 2013b).
