Brief bio: I joined the Plant Nutrition Biology Group of Huazhong Agricultural University for master degree in 2017, and graduated from Huazhong Agricultural University in 2021. My research interest is mainly focused on the molecular mechanism of NAC transcription factors involved in the regulation of nitrogen uptake and transport in rice plant. In this study, we found that a NAC transcription factor in rice, OsSNAC1, played a positive role in regulating NO3– uptake through directly binding to the upstream promoter regions of nitrate transporter genes OsNRT2.1/2.2 and OsNRT1.1A/1.1B, which activated their expression levels and improved the nitrogen use efficiency, plant growth, and yield production. Our results may provide a potential genetic approach for improving crop NUE in agriculture.

个人简介：我自2017年本科毕业于华中农业大学后加入该校植物营养生物学团队继续攻读硕士学位。硕士期间的主要研究方向为水稻NAC转录因子参与氮素调控的分子机制。我们在研究中发现，水稻NAC转录因子OsSNAC1可直接结合硝酸根转运基因OsNRT2.1/2.2和OsNRT1.1A/1.1B的上游启动子区，上调其表达水平，促进水稻植株对NO3–的吸收，提高氮利用效率，促进植株生长和产量形成。该研究可为农业领域提高作物氮利用效率提供一个潜在的遗传路径。
