Research Progress of PAL Gene and Its Function in Medicinal Plants
The phenylalanine metabolic pathway is a key metabolic pathway in plants,producing compounds such as flavonoids,phenolic acids,and lignans.These substances not only regulate plant growth,development,and stress resistance,but also employ in the prevention and treatment of diseases,which are major factors in determining the quality of medicinal plants.Phenylalanine ammonia-lyase(PAL)is the catalyst for the first reaction in the phenylalanine metabolic pathway and is the key and rate-limiting enzyme of this pathway.This review examines the fundamental features,control of expression of the PAL gene in medicinal plants,which serves as a foundation for further understanding the role of PAL in medicinal plants.
