Brief bio: I started my research career at Prof. Yuanwen Teng’s laboratory in the College of Agriculture and Biotechnology, Zhejiang University (Hangzhou, China) after finishing my undergraduate education in 2015. During my PhD study, I worked on the molecular mechanism of light-induced anthocyanin biosynthesis in red pears under the guidance of Professor Yuanwen Teng and Dr. Songling Bai. Anthocyanin biosynthesis is catalyzed by a series of enzymes encoded by structural genes, which are regulated by the MYB-bHLH-WDR (MBW) complex. The bHLH proteins of subgroup (SG) IIIf have been believed to be involved in the regulation of anthocyanin accumulation. In this study, we revealed that pear PpbHLH64, which belongs to SGIIIb, also positively regulates anthocyanin biosynthesis by forming MBW complex and is regulated by light at the transcriptional and post-translational levels. In the future, I will further study the mechanism of plant light signal transduction.

个人简介：我从2015年起进入浙江大学农业与生物技术学院学习，师从滕元文教授和白松龄研究员。在博士学习期间，我从事光诱导红梨花青苷合成分子机制的研究。植物花青苷的生物合成由结构基因编码的一系列酶催化，而结构基因的表达受到转录因子复合体MYB-bHLH-WDR（MBW）复合体的调控。前期的研究发现多个（SG）IIIf亚组的bHLH蛋白参与到花青苷的生物合成过程中。在本研究中，我们在红梨中鉴定得到一个属于SGIIIb亚组的bHLH蛋白，命名为PpbHLH64。PpbHLH64通过形成MBW复合体来促进花青苷的生物合成，且PpbHLH64在转录水平和翻译后水平受到光的调控。未来，我将更深入研究植物光信号传导的分子机理。
