The integrity of pollen wall structures is essential for pollen development and maturity in rice (Oryza sativa L.). In this study, we isolated and characterized the rice male-sterile mutant pollen wall abortion 1 (pwa1), which exhibits a defective pollen wall (DPW) structure and has sterile pollen. Map-based cloning, genetic complementation, and gene knockout experiments revealed that PWA1 corresponds to the gene...
