Brief bio: While studying for a master’s degree in Zhongkai University of Agriculture and Engineering, I mainly conducted research on the response of cut-wounding in stem-ends of cut lily. Since 2017, I am very fortunate to be able to pursue a Ph.D under the supervision of Prof. Junping Gao and Prof. Nan Ma of China Agricultural University. We found that phytochrome-interacting transcription factor RhPIF8 directly promoters the transcription and accumulation of B-BOX domain protein RhBBX28 at night, in rose petals. Furthermore, RhBBX28 inhibits the expression of succinate dehydrogenase RhSDH1, thereby affecting mitochondrial ROS homeostasis and regulating the senescence of rose petals.

科研经历简介：在仲恺农业工程学院攻读硕士学位期间，我主要进行了百合切花茎基部采切创伤的响应研究。2017年起，我非常幸运能在中国农业大学高俊平教授和马男教授指导下进行博士求学。我们的研究发现，在月季花瓣中，光敏色素互作因子RhPIF8直接促进B-BOX蛋白RhBBX28在夜间转录积累。进一步地，RhBBX28通过抑制琥珀酸脱氢酶RhSDH1的表达，从而影响线粒体ROS的动态平衡，调控月季花瓣衰老。
