Overexpression of YAB1 under the double CaMV 35S promoter induced semidwarf phenotypes in transgenic rice. A, Comparison between wild type and a YAB1-overexpressing line (Y4) at vegetative and reproductive stages. Bars = 15 cm. B, Overexpression of YAB1 affected cell elongation in stems. a and d, Epidermal cells. Arrows indicate the upper or lower limits of epidermal cells. Bars = 2 μm. b and e, Cells in the intercalary meristem. Bars = 10 μm. c and f, Cells in elongating zone. Bars = 10 μm. a to c, Wild type; d to f, YAB1-overexpressing plants. C, RNA gel-blot hybridization showing that all examined semidwarf lines (Y1, Y3–Y7, and Y9) showed overexpression of YAB1.
