Brief bio: I am mainly interested in how light signal shapes plant development using Arabidopsis as model. As a graduate student of Peking University, I had the great fortune of joining Prof. Xing Wang Deng lab from where I started my research career in 2012. In his lab, I have investigated how PIF protein stability is regulated by DET1 in the dark, and how light signal induces PIF3 protein degradation via EBF proteins after light exposure. After I got my Ph.D degree, I was lucky to join Dr. Ning Wei’s group at Yale University as a postdoctoral associate in 2016. At my current position, I elucidated the molecular basis of light induced cotyledon opening process of Arabidopsis seedling. Our study has revealed that a group of cotyledon-specific TCP transcription factors and the light responsive PIF transcription factors antagonistically modulate the expression of SAUR genes to regulate cotyledon opening of Arabidopsis seedling during dark to light transition.

简介：我主要用拟南芥为模式植物研究光信号如何调控植物的生长发育。在读研究生期间，我于2012年有幸加入北京大学邓兴旺教授实验室开始植物光信号传导的研究。在此期间，我主要研究光形态建成抑制因子DET1在暗中如何调控PIF蛋白稳定性以及在暗转光的过程中光如何通过EBF蛋白降解PIF3。毕业之后，我于2016年加入了耶鲁大学MCDB系主任Vivian Irish实验室的魏宁博士小组继续从事光调控拟南芥幼苗发育过程的研究。在此期间，我主要试图解析光信号如何调控拟南芥幼苗子叶打开的生理过程。主要发现，一类子叶特异表达的TCP转录因子与另一类可以响应光信号的PIF转录因子拮抗调控SAUR基因的表达，从而调控在暗转光的过程中拟南芥幼苗子叶的开闭。
