FIGURE 4.

The GSH level of eggplant leaves inoculated with R. solanacearum wild-type, RipAY-deficient, and T3SS-deficient strains. A, necrotic lesions on eggplant leaf 3 days postinoculation with R. solanacearum WT strain (WT), RipAY-deficient strain (ΔripAY), or T3SS-deficient strain (ΔhrcU). Mock, inoculation of buffer without bacteria as a control. B, the GSH level of total lysate extracted from eggplant leaves inoculated with the indicated R. solanacearum strains at 1 day postinoculation was measured as described under “Experimental Procedures.” Values represent the mean ± S.E. (error bars) (n ≥ 7). ****, p < 0.0001, one-way analysis of variance post hoc test (Turkey's multiple comparison test).
