Brief bio: After completing bachelor’s degree at Northwest A & F University in 2017, I entered the group of Prof. Wen-Wu Guo, Huazhong Agricultural University. During my PhD studies, with the help of Dr. Feng-Quan Tan, I mainly focused on evaluating metabolic characteristics of citrus allotetraploid and studying the mechanism responsible for these novel traits in polyploid. We found that allopolyploidization caused extensive metabolic variation in citrus fruit, including fruit acidity, content of carotenoid and flavonoid. We then performed a global acetylome analysis, which revealed that acetylome reprogramming plays an important role in trait evolution during polyploidization through regulation of enzyme activity and protein abundance. Collectively, we established a dataset of lysine acetylation in citrus fruit and provided a theoretical basis for the generation of new traits in polyploid.

个人简介：本人2017年毕业于西北农林科技大学，获农学学士学位，同年进入华中农业大学园艺植物教育部重点实验室郭文武课题组，攻读博士学位。主要研究柑橘异源四倍体体细胞杂种果实品质性状变异及其形成机理。研究发现，相比其亲本，异源四倍体化伴随着广泛的果实性状变异，包括有机酸含量、类胡萝卜素含量、类黄酮含量等；定量乙酰化修饰组学技术发现，异源多倍体化导致的乙酰化组重编程，可能通过调节酶活性和蛋白质丰度影响柑橘果实代谢。该研究建立了柑橘果肉赖氨酸乙酰化修饰组数据集，为多倍体化导致的新性状产生提供了新的理论基础。
