The physiological response of the A. thaliana leaf to drought stress. Appearance of stoma. Scale bar, 2.5 µm (A), and stomatal aperture in detached leaves of plants inoculated with either wild type FZB42 or the epsC mutant (B). Values are shown as means, with the whiskers representing the standard error (SE, n = 18). Different letters above each column indicate statistically significant (p < 0.05) differences in mean performance.
