Comparison of the wider transgenic siliques to the wild-type siliques. The transversal sections show that the wider transgenic siliques have more cells than the wild-type siliques. A, There are 142.2 ± 10.4 epidermal cells in a transversal section of a wild-type silique at anthesis stage. B, There are 169.2 ± 14.2 epidermal cells in a transversal section of a wider transgenic silique at anthesis stage. C, There are 160.9 ± 11.9 epidermal cells in a transversal section of a wild-type silique at a stage 2 d after anthesis. D, There are 205.5 ± 17.5 epidermal cells in a transversal section of a wider transgenic silique at a stage 2 d after anthesis. E, There are 163.8 ± 10.5 epidermal cells in a transversal section of a wild-type silique at a stage 5 d after anthesis. F, There are 236.8 ± 20.1 epidermal cells in a transversal section of a wider transgenic silique at a stage 5 d after anthesis. G, There are 164.3 ± 12.8 epidermal cells in a transversal section of a wild-type silique at a stage 10 d after anthesis. H, There are 249.9 ± 20.1 epidermal cells in a transversal section of a wider transgenic silique at a stage 10 d after anthesis. Cp, Carpel. Bars = 25 μm.
