a Bacterial population sizes in the ΔxopC2-inoculated leaves of the wild-type, IE-17, IE-D391A-2, and IE-N396A-14 transgenic seedlings. The 3-week-old seedlings were treated with mock and DEX followed by spraying with Xoc ΔxopC2 after 24 h. Bacterial populations were determined at 4 days post-inoculation (dpi). Data are shown as means ± standard error (SE) (n = 3 technical replicates per measurement). The letters (a, b) indicate a statistically significant difference in bacterial population sizes as revealed by one-way ANOVA, Tukey’s honest significance test. b Stomatal conductance in the leaves of the wild-type, IE-17, IE-D391A-2, and IE-N396A-14 transgenic lines after challenging with ΔxopC2. The 3-week-old seedlings were pretreated with DEX and mock followed by spray inoculation with ΔxopC2 and mock control. Stomatal conductance was measured at 2 dpi. Data are shown as means ± SE (n = 8 technical replicates per measurement). These experiments were independently repeated 3 times with similar results in a and b. The letters (a, b) indicate a statistically significant difference in stomatal conductance of the xopC2 transgenic IE-17 seedlings between mock and DEX treatments as revealed by one-way ANOVA, Tukey’s honest significance test.
