Brief bio: During my Ph.D. study in Dr. Yuehui He’s laboratory, I studied on plant environmental epigenetics, with a main focus on molecular epigenetic regulation of flowering time in Arabidopsis. Since joining the Peking University Institute of Advanced Agricultural Sciences, I have been mainly investigating molecular epigenetic mechanisms for vernalization in both wheat and Arabidopsis. I am committed to the genetic improvement of agronomic traits in wheat. In this work, we have uncovered the molecular circuitry underlying embryonic resetting of the ‘vernalized state’ of a potent flora repressor as well as further embryonic activation of this repressor by the ABA-pathway transcription factor ABI3 in Arabidopsis.

个人简介：我在何跃辉教授实验室攻读博士学位期间，从事植物环境表观遗传学研究，主要研究组蛋白修饰介导的拟南芥开花时间调控。入职北京大学现代农业研究院以来，主要研究小麦和拟南芥的春化调控机制以及其它开花时间调控机制，并致力于小麦相关农艺性状的改良。在这项工作中，我们发现了拟南芥胚胎发育过程中亲本的春化状态被ABA途径的转录因子ABI3重置及进一步激活的机制
