Brief bio: During four-year undergraduate education in the major of biological science, I developed a strong interest in plant science, especially plant responses to abiotic stresses. After the bachelor study, I was fortunately admitted to the China Agricultural University as a Ph.D. candidate under the direct supervision of Prof. Jing Zhang. My research interest is to understand the mechanisms how nitrate regulates root development in Arabidopsis thaliana. In this research project, we found that low nitrate restricts auxin distribution in the root tips via the CHL1/NRT1.1/NPF6.3-mediated nitrate signaling pathway, which in turn represses the expression of WOX5 and PLTs, ultimately promoting DSC differentiation in the primary root tip. During my Ph.D. study, I have acquired the expertise encompassing mainly the area of genetics, molecular biology, and cell biology. Currently, I continue studying the regulatory mechanisms of nitrate in root architecture modification in Prof. Jing Zhang’s lab. Hopefully, these researches may enable future advances in more efficient and sustainable crop production.

自我介绍：通过大学四年的生物学学习，我对植物科学尤其是植物抗逆方向产生了浓厚的兴趣。本科毕业后，我有幸进入中国农业大学张静教授实验室就读博士。我主要致力于硝酸盐调节拟南芥根发育机理方面的研究。在这个课题的研究过程中，我们发现低氮通过抑制硝酸根信号通路受体CHL1/NRT1.1/NPF6.3的表达进而抑制生长素在根尖的积累，从而减弱WOX5和PLTs基因的表达，最终促进根尖干细胞的分化。在攻读博士期间，我积累了丰富的遗传学，分子生物学和细胞生物学相关的理论知识和实验经验。目前，我在张静教授课题组继续研究硝酸盐对植物根系结构的调控机理。希望这些研究能够为提高作物产量和农业的可持续发展提供新的理论依据。
