Stomatal aperture of slnpr1 mutants and wild type (WT) plants under drought stress. Stomatal condition in leaves of (a) WT plants and (b) slnpr1 mutants after 3 days’ drought stress. (c) Stomatal length, (d) stomatal width, and (e) stomatal aperture after 3-day drought stress. The error bars indicate the standard deviations of three biological replicates. Asterisks indicate significant differences as determined by Student’s t-test (*, P < 0.05; **, P < 0.01).
