CAG-induced stomatal movement in A. thaliana leaves. a Effects of different concentrations of CAG on stomatal movement of A. thaliana leaves. b The aspect ratio of stomatal aperture. c Time effect of CAG-induced stomatal movement. d The stomates of A. thaliana leaves were treated with CAG at different concentrations. Bar = 2 µm. e, f A part of the stomates on the epidermis from A. thaliana leaves. Bar = 5 µm, Bar = 20 µm. Image f was taken at 20x, and images e and d were each magnified by 2.5x. Uppercase letters indicate differences between groups, lowercase letters indicate differences within groups. Means with different letters are significantly different at P < 0.05
