Brief bio: I completed my Ph.D study from School of Life Science, Lanzhou University. After graduation, continued to work in professor Hou’s research group. Through forward genetic screening, I identified the dominant-negative effect mutant topp4-1 of Arabidopsis type I protein phosphatase (TOPP). The discovery of this mutant led me into the research field of TOPP regulation of plant growth and development and stress response, and I have been devoted to this direction since then. By constructing and studying multiple TOPP family mutants, we confirmed that TOPP plays an important role in regulating biological and abiotic stress in plants, and revealed that TOPP is involved in autophagy response by regulating the phosphorylation state of ATG13a.

个人简介：我博士毕业于兰州大学生命科学学院。毕业后继续在侯岁稳教授课题组工作。我通过正向遗传学筛选到拟南芥I型蛋白磷酸酶（TOPP）的显性负效应突变体topp4-1，这个突变体的发现将我引入了TOPP调控植物生长发育、逆境响应的研究领域，此后一直致力于这一方向的工作。通过构建并研究TOPP家族多重突变体，我们证实了TOPP在调控植物生物和非生物胁迫中的重要功能，并揭示了TOPP通过调节ATG13a的磷酸化状态参与植物自噬反应。
