Integrity of epidermal cells after SMS treatment visualised by SEM. (A) Surfaces of leaves of A. thaliana Col0 were observed by SEM after SMS (10×). (B) Damage to trichomes after SMS (10×) compared to non-treated leaves. (C) Surfaces of leaves of the glabrous mutant gl1 of A. thaliana Col0 observed by SEM after SMS (10×). All observations of this figure were repeated 25 times on 5 different leaves. Representative samples are shown.
