Rice (Oryza sativa L.) is sensitive to high temperature ( 35 deg C), especially during flowering, which results in spikelet sterility and reduced grain yield. With global warming, breeding rice varieties that can tolerate high temperature is needed. However, little is known about germplasm resources...
