Analyze of stomatal aperture size. a Images of stomatal apertures from epidermal peels of Col-0 and TaGAPC1–overexpressing (OE1–3 and OE1–10) lines after withholding water for 15 d. Scale bars: 10um. b The stomatal aperture size was determined by measuring the width to length of stomates in epidermal peels from Col-0 and TaGAPC1–overexpressing (OE1–3 and OE1–10) lines after withholding water for 15 d. Error bars indicate ±SD (n = 50). Significant differences were assessed with one-sided paired t-tests (*, P < 0.05; **, P < 0.01). Three biological experiments were performed, which produced similar results
