Scanning electron micrographs of leaf epidermal cells of WT and transgenic Arabidopsis plants. (A–E) Adaxial epidermis in the seventh rosette leaf from WT (A), OXPCF10 (B), PCF10SRDX (C), OXCIN8 (D) and CIN8SRDX (E). (F–J) Adaxial epidermis in the eighth rosette leaf from WT (F), OXPCF10 (G), PCF10SRDX (H), OXCIN8 (I) and CIN8SRDX (J). (K–O) Abaxial epidermis in the seventh rosette leaf from WT (K), OXPCF10 (L), PCF10SRDX (M), OXCIN8 (N) and CIN8SRDX (O). (P–T) Abaxial epidermis in the eighth rosette leaf from WT (P), OXPCF10 (Q), PCF10SRDX (R), OXCIN8 (S) and CIN8SRDX (T). (U) Seventh and eighth rosette leaf epidermal cell number for WT, OXPCF10, PCF10SRDX, OXCIN8 and CIN8SRDX. Asterisks indicate statistically significant differences (*P<0.05, **P<0.01, compared with WT by Student’s t-test). Errors bar represent the SD of three biological repeats (n=200 each). Scale bars: 100 μm.
