 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.
