a SEM observations of Cris-OBV and WT. b Analysis of the ratio of open stomata to total stomatal number in the lower epidermal cells. c TEM observations of Cris-OBV and WT. d Analysis of chloroplast number in the vascular bundle. GC, guard cell; Chl, chloroplast; SG, starch granule. Asterisks indicate statistically significant differences determined using a t-test (*P < 0.05; **P < 0.01). Scale bars: (a1–a4) 100 μm, (a5–a6) 200 μm, (c1–c2) 5 μm, (c3–c4) 0.5μm, (c5–c6) 0.2 μm
