Size and number of adaxial pavement cells in leaves of wild-type and mutant plants. Epidermal cell size and number in wild type, gebp gpl1,2,3 quadruple mutant, cpr5-2, and gebp gpl1,2,3 cpr5 quintuple mutant. A, Adaxial pavement cell size of third leaves of 3-week-old plants grown in soil. Scale bars: 200 μm. B, Class distribution of epidermal cell size (top histogram), epidermal cell density (bottom left), and estimated epidermal cell number per leaf (bottom right). Class distribution of cell size was performed by measuring cell area from third leaves of 3-week-old plants grown in soil (Columbia, n = 147; quadruple mutant, n = 149; cpr5, n = 294; quintuple mutant, n = 191) using ImageJ software. The total number of epidermal cells per leaf was estimated by dividing the leaf area by the average cell area.
