Fourth leaf width and guard cell size in WT and transgenic lines. a Images of fourth leaves of WT and transgenic lines. Bars = 1 cm. b Measurements of the maximum fourth leaf width in WT and transgenic lines. Values indicate the mean, and error bars represent the SD (n >10). An asterisk indicates a significant difference between the WT and transgenic lines (t-test; P < 0.05). c Images of stomata in WT and transgenic lines. Bars = 5 μm. d Percentage of stomata with various guard cell lengths in WT and transgenic lines (n > 500)
