Fig. 3: Overexpression of LsAP2 leads to small and crinkly leaves.

a Plant morphology of the WT, three LsAP2 overexpression (LsAP2-OE) lines, and an LsAP2 knockout (LsAP2-KO) line. White arrows indicate the leaves curled downwards with bulges. b Expression of LsAP2 in different lines. The values are means ± SDs (n = 3). The data were normalized to a value of 1 for the WT. c Leaf venation patterns in different lines. Black arrows, schematic representation of the primary leaf veins. d Total leaf area of one-month-old plants in different lines. The values are means ± SDs (n = 10). e Adaxial surface of leaves from the WT and LsAP2-OE plants. f, g Scanning electron micrographs of adaxial epidermal cells of mature leaves from WT (f) and LsAP2-OE (g) plants. In (b) and (d), different letters indicate significant differences determined by one-way ANOVA with Tukey’s post hoc test (P < 0.05). Scale bars: (a, c, e) 5 cm; (f, g) 20 μm
