Brief bio:

        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.

个人简介：

本科进入实验室进行科研训练，感受到了科研的魅力。于是考取了西南大学，在水稻所何光华教授和王楠副教授的共同指导下主要研究水稻雄性不育，通过不断学习与进步，对水稻雄性不育及机制有了一定的了解。在此期间，本人鉴定了一个保守的雄性不育突变体pwa1，其败育的原因主要集中在缺陷的花粉壁上。进一步研究发现TIP2转录因子调控PWA1的表达，并与PWA1发生互作，共同参与对花药外壁的调控；PWA1本身具有一定的转录激活活性，通过Os12BGlu38参与对花粉内壁的调控。该研究发现了一个新组分PWA1调控水稻花粉的发育，为杂交水稻育种提供了新资源。
