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.
