 Brief bio: I joined Xing Wang Deng’s PKU lab in 2013, and engaged in the research on the mechanisms of Arabidopsis SAUR family genes mediating seedling morphogenesis. The main findings are as follows: 1. During the dark to light transition, Arabidopsis lirSAURs exhibit organ-specific light-responsive patterns, and promote cotyledon expansion and hypocotyl growth stagnation. 2. SAUR17 maintains the apical hook and cotyledon closure though competitively associating with PP2C-D1 and protecting it from inhibitory SAURs such as SAUR50. Now, I’m interested in how light and hormonal signals cross talk to regulate plant skotomorphogensis.

个人简介：2013年进入北京大学邓兴旺实验室，从事拟南芥SAUR家族基因调控幼苗形态建成的机制研究。主要发现：一、拟南芥lirSAUR基因能够器官特异性地响应光信号，从而促使黄化苗在暗转光的过程中子叶延展，下胚轴生长停滞；二、SAUR17通过竞争性地结合PP2C-D1从而解除SAUR50对PP2C-D1酶活的抑制，从而维持着黄化苗顶端弯钩和子叶的闭合。目前主要对光和植物激素交叉互作调控植物的形态建成比较感兴趣。
