Research Progress on the Biosynthesis of Chlorogenic Acid in Plant
Chlorogenic acid(CGA)is a common phenolic compound found in plants,primarily sourced from coffee,tea,fruits,and vegetables.Although chlorogenic acid is synthesized via the phenylalanine metabolic pathway,its synthesis and regulatory mechanisms remain largely unclear.This review summarized key rate-limiting enzymes and transcription factors involved in chlorogenic acid biosynthesis,examines biological and non-biological factors affecting its content,and aimed to provide theoretical support and target genes for future regulation of chlorogenic acid synthesis in plants.
