Figure 2. Virulence assays of the wild-type and rpfG-, hgdA- and hgdC-related single, double and triple mutant strains on rice cv. Jingang 30.

(A) The length of disease lesions was measured at 14 days after pressure inoculation of the wild-type (WT), ΔrpfG, complemented ΔrpfG (rpfG), ΔhgdA, ΔhgdA/hgdC, ΔhgdA/rpfG, ΔrpfG/hgdC, ΔhgdA/rpfG/hgdC strains, respectively. Ten to 15 leaves were scored for each strain; means ± standard error (SE) are shown. (B) In planta bacterial populations of Xoc RS105, ΔrpfG and ΔrpfG(rpfG) at the specific time points after inoculation. Data are presented as means ± SE.
