Brief bio:

During the master’s degree, under the guidance of Professor Yajun Xi and researcher Ertao Wang from the Institute of Plant Physiology and Ecology of the Chinese Academy of Sciences, I mainly engaged in the study that the molecular mechanism of legume small G protein ROP involved in root nodule symbiotic signal transduction. After that, I entered the School of Life Sciences of Fudan University in September 2017 and pursued a PhD under the guidance of Professor Hongquan Yang. During my Ph.D., my main research work was the molecular mechanism of the cross-interaction of blue light signal and gibberellin signal mediated by the blue light receptor CRY1 in Arabidopsis. In this study, we found that CRY1 controls photomorphogenesis through inhibition of GA-induced degradation of DELLA proteins and GA signaling, which is mediated by CRY1 inhibition of the interactions of DELLA proteins with GID1 and SLY1, respectively.

题目: Blue light-dependent interactions of CRY1 with GID1 and DELLA proteins regulate gibberellin signaling and photomorphogenesis in Arabidopsis

个人简介:

硕士期间在奚亚军教授以及中科院植物生理生态研究所王二涛研究员指导下主要从事豆科植物小G蛋白ROP参与根瘤共生信号传导的分子机理研究。2017年9月开始于复旦大学生命学院杨洪全教授的指导下攻读博士学位。博士期间的我主要的工作是拟南芥蓝光受体隐花素CRY1所介导的蓝光信号与赤霉素信号交叉互作的分子机理研究。本研究主要揭示了CRY1通过分别抑制DELLA蛋白与GID1和SLY1的互作，抑制GA诱导的DELLA蛋白降解从而抑制GA信号来调控植物光形态建成。
