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.
