Brief Bio: After I graduated from North West Agriculture and Forestry University in bioengineering in 2012, I was fortunate to join the research group of professor Tao Wang of the College of Biology, China Agricultural University to pursue a doctorate degree, where I began to carry out research on the resistance biology and symbiotic nitrogen fixation biology of Medicago truncatula. Under low nitrogen (N) conditions, the root system growth and symbiotic nodulation can be coordinated to maintain carbon-nitrogen balance in legumes. In this study, I found that a Receptor-Like Kinase (RLK) CRA2 plays an inportant role in the regulation of root system architecture and symbiotic nodulation under low-N condition. Further researches found that the small peptide MtCEP1 is a ligand of CRA2, and MtCEP1-CRA2 regulates root development and symbiotic nodulation through two independent signaling pathways of auxin and ethylene signaling. I continue to conduct postdoctoral research in Professor Tao Wang’s research group to explore the adaptation mechanism of legumes to low-N and the symbiotic nodulation regulation mechanism.

个人简介：我于2012年毕业于西北农林科技大学生物工程专业，而后有幸加入中国农业大学生物学院王涛教授课题组攻读博士学位，开展截形苜蓿的抗逆生物学和共生固氮生物学研究。在低氮条件下，豆科植物会协调根系发育和共生结瘤以达到碳氮平衡，本研究发现一个类受体激酶CRA2在低氮下调控根系结构和共生结瘤中起到重要作用。进一步研究发现，MtCEP1为CRA2的配体小肽，并且MtCEP1-CRA2通过生长素和乙烯信号两条独立的信号通路调控根系发育和共生结瘤。我目前继续在王涛教授课题组进行博士后研究，探索豆科植物对低氮的适应机制和共生结瘤调控机制。
