Drought stress causes yield loss in rice by inhibiting panicle exsertion which is driven by peduncle elongation near flowering. To elucidate the mechanism of peduncle elongation, we examined the drought sensitivity of corresponding genes encoding xyloglucan endotransglycosylase/hydrolase (XTH), a cell wall-loosening enzyme essential for cell elongation in the peduncle elongation zone at heading stage. When drought was imposed 6 days before heading, peduncle elongation rate (PER) was inhibited… CONTINUE READING
