FIG. 5.

S. enterica serovar Typhimurium does not trigger stomatal closure. (A) Confocal microscopic images of lettuce leaf exposed to saline (control), S. enterica serovar Typhimurium (STm), and P. syringae pv. tomato (Pst) DC3000 for 2 h in light. White arrows indicate stomata. (B) Stomatal aperture in lettuce leaf exposed to saline (control), S. enterica serovar Typhimurium, and P. syringae pv. tomato DC3000. Results are shown as means plus standard deviations (error bars) (n = 60). Different letters indicate significant differences (P < 0.05) between the means by analysis of variance by the Tukey-Kramer multiple-comparison test.
