Figure 4

Spikelet fertility and mature pollen viability of transgenic lines and WT under normal conditions. Photographs of mature spikelets harvested from control plants and transgenic lines were taken (A). Grain length, grain width, spikelet weight, and spikelet fertility of control plants and transgenic lines (B). Mature pollen grains from control plants and transgenic lines were stained by I2-KI (C). Data are means ± SE calculated from four independent experiments. Asterisks indicate significant difference between WT and transgenic lines (*p <0.05; **p <0.01).
