Brief bio:
In 2018, I graduated from the Horticulture College of Qingdao Agricultural University with a bachelor’s degree in Horticulture, and then entered the Horticulture College of China Agricultural University to study for a master’s and doctoral degree in fruit science. The research direction is mainly related to the molecular mechanism of response of apple rootstocks to low nitrogen stress. Nitrogen is an essential macronutrient for all life and central to plant primary metabolism, directly affecting plant growth and development. In China, apple planting areais large and its distribution is wide. The lack of soil nutrients in orchard restricts the yield and quality of fruit trees, how to improve the nutrient absorption of apple trees is a problem that needs to be solved in current production. Therefore, we utilized multi-omics analisis to investigate the molecular mechanism of apple rootstocks in response to low nitrogen stress. In our study, we found that the transcription factor bHLH130 could regulate the metabolic flux between the two complementary pathways of flavonoid and lignin biosynthesis, and improve the nitrogen uptake efficiency of apple rootstocks. The results of this study extend the understanding of transcriptional regulation mechanism of apple rootstocks in response to nitrogen stress.

个人简介：
2018年毕业于青岛农业大学园艺学院园艺专业获得学士学位，后进入中国农业大学园艺学院果树学专业硕博连读攻读博士学位。研究方向主要是苹果砧木低氮胁迫响应的分子机制相关研究。氮是所有生命必需的大量营养元素，是植物初级代谢的核心，直接影响植物的生长发育。我国苹果种植面积大，分布范围广泛，果园土壤养分缺乏限制了果树的产量和品质，如何提高苹果树体养分吸收是目前生产上需要解决的问题。因此，我们利用多组学分析方法探究苹果砧木响应低氮胁迫的分子机制。在我们的研究中发现转录因子bHLH130能够调节类黄酮和木质素生物合成的两条互补途径之间的代谢通量，提高苹果砧木的氮素吸收效率。该项研究结果扩展了对苹果砧木氮胁迫响应过程中转录调控机制的认识
