In Planta virulence test of WT, ΔdgcA, OdgcA and CdgcA strains.
(a) Leaf segments of rice cultivars IR24 and Zhonghua 11 (ZH11) showing different degree of rice blight symptoms. Typical leaves were photographed after infection with the four individual strains for 14 days. (b) The mean lesion of IR24 (left column) and Zhonghua 11 (right column with slash) lengths 14 days post inoculation. Leaf without bacterial inoculation were performed as a negative control. The values were means ± standard deviations for triplicate assays. Significances of differences by Student’s t-test are indicated (**P < 0.01; *P < 0.05; NS, P > 0.05).
