Brief bio: After completing my BS and MS studies, I joined the department of ornamental horticulture at China Agricultural University to pursue my PhD degree under the supervision of prof. Bo Hong, Junping Gao, and Chao Ma. My PhD thesis is about the regulatory mechanism of rose petal abscission. It has been well-known that auxin and sucrose can inhibit organ abscission in plants. However, the interaction of auxin and sucrose involved in organ abscission remains unknown. In our study, we found that auxin modulates sucrose transport during petal abscission, and that this process is regulated by a RhARF7-RhSUC2 module in the petal abscission zone. This study makes me fascinated about the regulatory mechanism of flower development process. In the future, I hope I can get more interesting discoveries from my studies.

个人简介：在完成学士和硕士学习后，我有幸加入洪波、高俊平和马超教授课题组攻读博士学位，开展关于月季花瓣脱落分子调控机制方面的研究。生长素和蔗糖对植物器官脱落均起抑制作用，但二者的相互作用关系尚不明确。我们的研究发现在花瓣脱落过程中，生长素调控了蔗糖向月季花瓣的运输，进而调节花瓣脱落进程，并且这一过程是通过生长素响应因子RhARF7调控蔗糖运输蛋白RhSUC2基因的表达来实现。通过这项研究，我对植物花器官发育调控机制产生了浓厚的兴趣，希望在以后的研究工作中获得更多有趣的发现。
