Virulence test of Xanthomonas oryzae pv. oryzae strains in rice. a Wildtype, ∆catB, ∆oxyR, ∆catB(pBBR-catB) and ∆oxyR(pBBR-oxyR) strains were inoculated on the rice leaves (6 weeks old) by using the leaf-clipping method. The disease symptoms were observed at 14 days post-inoculation. b The lesion lengths were recorded from 10 inoculated leaves for every strain. c Bacterial numbers in the top 20 cm of each lesion leaf were scored. Data represent the mean and standard deviations of three independent experiments, and different letters above the bars denote statistically significant differences (P < 0.05, Student’s t test)
