Entering the laboratory for scientific research training during undergraduate, I deeply felt the charm of scientific research and so I was admitted to Southwest University. Under the joint guidance of Professor He Guanghua and Associate Professor Wang Nan, I mainly studied male sterility in rice. Through continuous learning and progress, I had a certain understanding of rice male sterility and its mechanism. During this period, I identified a conserved male-sterile mutant pwa1, whose abortion pollen was mainly caused by the defective pollen wall. Further research found that TIP2 transcription factor regulates the expression of PWA1 and interacts with PWA1 to participate in the regulation of the anther epidermis; PWA1 itself has a certain transcriptional activation activity, and participates in the regulation of the pollen intine through Os12BGlu38. In this study, a new component, PWA1, was found to regulate the development of rice pollen, providing a new resource for hybrid rice breeding.
