Brief bio: I graduated from Hunan Agricultural University in 2018 (B.S). In the same year, I become a master student in State Key Laboratory of Tea Plant Biology and Utilization of Anhui Agricultural University under the supervision of Prof. Chuankui Song. During my M.S.work, I focused on the funtional characterization of UDP-glucosyltransferases involved in the regulation of plant disease in tea plants (Camellia sinensis). Interestingly, we found that the content of salicylate glucose ester (SGE), which was almost undetectable under normal condition, was significantly increased when tea plants was infected by tea grey blight pathogen. Futher, a glucosyltransferase UGT87E7 in tea was identified whose encoded protein could specifically glucosylate salicylic acid to form SGE, which plays a key role in disease resistance by influencing the homeostasis of salicylic acid in plants.

个人简介：我于2018年本科毕业于湖南农业大学，同年有幸加入安徽农业大学茶树生物学与资源利用国家重点实验室宋传奎教授团队学习并开展科学研究。期间，主要研究小分子物质糖苷化在茶树抗病中的功能及机制研究。我们研究中发现，水杨酸葡萄糖酯（水杨酸的羧基取代物）在正常茶树中含量很低，几乎无法检测，而当茶树遭受到轮斑病菌侵染时，水杨酸葡萄糖酯的含量会显著上升。进一步，我们通过原核表达及茶树的瞬时转化体系，发现茶树糖基转移酶UGT87E7能够特异性糖基化水杨酸羧基位点，并形成水杨酸葡萄糖酯，并发现基因在茶树体内水杨酸的动态平衡及抗病中发挥重要作用。
