Brief introduction: I joined in Bing Liu lab since June of 2019, and my focused research was to uncover the underlining mechanism controlling sensitivity and response of male meiosis and recombination to temperature alterations. We found that increase of environmental temperature can inhibit meiotic recombination by suppressing SPO11-dependent DSB formation and the organization of chromosome axis and synaptonemal complex. Meanwhile, I am working on two other projects, which try to understand the role of gibberellin in modulating meiosis in Arabidopsis, and the interactions among molecular factors involved in DSB formation and repair.

个人简介：我就读于中南民族大学生物工程专业，并于2019年6月加入刘冰博士的实验室。我主要研究的科学问题是拟南芥雄性减数分裂和同源重组如何响应环境温度的变化。我们发现环境温度升高能通过抑制SPO11依赖的DNA双链断裂形成和联会复合体的形成，从而抑制雄性同源重组的发生。同时，我正在进行的另外两个研究课题是赤霉素调控拟南芥雄性减数分裂的分子机制，以及DSB形成与修复相关的遗传因子之间的互作机制。
