Data are presented as mean ± SE. Leaf widths were measured through the middle region of the leaves at mature stage. Statistically significant differences from the respective wild type at *P < 0.05 and **P < 0.01 were detected using t tests (n = 20). ND, not determined; PPB, primary panicle branches; SPB, secondary panicle branches.
