Figure 2.

Phenotype of tcp20 knockout plants. Leaves of 10-d-old Arabidopsis seedlings were analyzed with SEM followed by pavement cell size analysis. A, Representative SEM images of the abaxial side of 10-d-old first leaves from wild-type and tcp20 knockout plants. B, Cell drawings made based on the representative SEM images in A. Bars = 100 μm. C, Diagram showing the average pavement cell sizes in wild-type and tcp20 knockout plants. Pavement cells in leaves of tcp20 knockout mutants were significantly bigger than in wild-type leaves. D, Diagram showing average leaf sizes of 42-d-old tcp20 knockout plants in comparison with Col-0 wild-type plants. The mean centroid size is plotted (Supplemental Data S1). No significant difference could be detected.
