Brief bio: Driven by my interest in life science, I entered into the lab of my graduate advisors Professor Jingquan Yu and Professor Yanhong Zhou, where I started to explore the regulation of light signaling in plant growth and adaptation under adverse environmental conditions. We found that gradual cooling accompanied by short days and decreased R/FR ratios can induce phyA-dependent SlHY5 accumulation in tomato plants. Increased accumulation of SlHY5 resulted in a decrease in the GA/ABA ratio with growth cessation and an increase in cold tolerance. Phytochrome-dependent SlHY5 may function as a critical regulator of the trade-off between plant growth and stress response in plants. After graduation, I joined the lab of Professor Tianlai Li (Academician of China Engineering Academy) at the Shenyang Agricultural University. Currently, I am still working to determine the precise molecular mechanisms transducing the signals from light and temperature perception to maintain plant growth and adaptation, and investigating the complex integration of light, temperature and hormones signals in plants.

工作简介：出于对生命科学的好奇，我于2012年9月起在浙江大学喻景权教授和周艳虹教授实验室进行硕博连读。博士期间，主要开展光信号对植物生长发育与逆境抗性调控的研究。我们发现从温暖到寒冷的季节变化过程中，温度的降低伴随着日照的变短、红光与远红光比例的降低，这种环境条件下依赖于光敏色素A的番茄HY5蛋白大量积累。HY5的积累导致赤霉素的降低及脱落酸的增多，从而抑制植物的生长，但提高其耐低温性。而温暖的夏季，则HY5相对较少，植物中赤霉素含量较高，而脱落酸降低，这样促进植物的生长。这表明光信号转录因子HY5在调节植物生长与抗性平衡间起着重要的作用。2017年6月毕业后，加入沈阳农业大学李天来院士团队并继续设施蔬菜生长发育及逆境调控机制的研究，目前主要方向包括：植物对光-温变化的感知与响应，光-温信号的互作机制、光合作用环境适应机理以及植物激素的生理调控。
