Leaf phenotypes of mGRF6b (a), mGRF7a (b), mGRF12a (c), and GRF12b (d) overexpression (OE) transgenic plants. Photographs, cell cytology, leaf area, leaf cell area, and calculated leaf cell number of the fifth leaves from 2-month-old mGRF6b, mGRF7a, mGRF12a, and GRF12b OE plants are shown. Bar = 2 cm (top) and 50 μm (bottom). Data was presented as means ± SD (n = 6–10 for leaf area, n = 100–120 for leaf cell area, n = 6–10 for leaf cell number). *Ρ < 0.05 determined by Student’s t-test
