Brief bio: I started my Ph.D. study in 2019 and completed the Ph.D. thesis in 2022 under the joint guidance of professor Shuangcheng Li and lecturer Ting Zou at Rice Research Institute, Sichuan Agricultural University. My major research interest is cloning and functional analysis of key genes regulating rice male reproduction. During this period, I identified a male-sterile rice mutant, sts1, with delayed tapetum degradation and aborted pollen wall formation, and confirmed that STS1 encodes a novel lipase containing a DUF726 domain. Meanwhile, STS1 may affect anther lipid biosynthesis by interacting with OsPKS2 and OsACOS12, thereby regulating the development of tapetum and pollen wall in rice. This discovery provides new knowledge for plant pollen development and a potential genetic resource for hybrid rice breeding. In the future, I hope to have the opportunity do researches on the functional analysis and regulatory mechanism of key genes in plant development.

个人简介：我从2019年开始攻读博士学位，在四川农业大学水稻研究所李双成教授和邹挺讲师的共同指导下，于2022年完成了我的博士论文。我主要的研究方向是水稻雄性生殖发育关键基因的克隆与功能解析。在此期间，我发现了一个花药绒毡层降解延迟和花粉壁缺失的水稻雄性不育突变体sts1，并证实STS1编码一个含有DUF726结构域的新型脂肪酶。同时，STS1可能通过与OsPKS2和OsACOS12直接互作来影响花药脂质合成，从而调控水稻绒毡层和花粉壁的发育。这一发现为植物花粉发育提供了新的知识，并为杂交稻育种提供了有应用潜力的基因资源。今后，我希望能有机会从事植物关键基因功能解析和调控机制方面的研究。
