Fig. 2: Histological analysis of leaf and stem of WT and TG plants.

a Cross-section images of WT and TG leaves. Scale bar, 100 µm. b Statistical analysis of leaf vein number between representative WT and TG plants (n = 5). c The representative leaf epidermis of WT and two TG lines. Scale bar, 50 µm. d The number of leaf epidermis cells between WT and two TG lines (n = 5). Data are shown as means with standard error. Asterisks (***) indicate a significant difference between WT and each TG line at P < 0.001 by Student’s t-test
