Overexpression of pPLAIIIδ affect leaf cell development. (A) Leaf epidermal cells from WT, KO, and OE lines. Reduced convolution of epidermal cells (first and second columns) in OE plants was observed compared with WT and KO. The leaf vertical section of WT, KO OE plants (third column) showed aberrant mesophyll cells that almost completely occupied the spaces in OEs. Bars = 50 μm. (B-G) Measurements of cell length, skeleton end points, circularity, APS, neck width, and lobe length of epidermal pavement cells, respectively. All values are means ± SE of ≥15 samples. * and ** indicate significant differences at P ≤0.05 and at P ≤0.01, respectively, by Student’s t test, compared with WT. ad, adaxial; ab, abaxial.
