Figure 4

Effect of abscisic acid (ABA) (100 µM) on stomatal pore length, width, and stomatal aperture of WT and tgg single and double mutants. Length (A) and width (B) of the stomatal pore in WT, tgg single and double mutants after mock treatment or treatment with ABA. Different letters (a, b and c) above the bars indicate significant differences between WT, tgg1, tgg2 and tgg1 tgg2 for each treatment as determined by a Kruskal-Wallis test followed by a Tukey test for pairwise comparisons (p < 0.05). (C) Stomatal aperture in WT, tgg single and double mutants after mock treatment or treatment with ABA. Bars represent the means ± SE (n = 200). Asterisks above bars indicate a significant effect of the ABA treatment on stomatal aperture (* p < 0.05).
