摘要
苯丙烷代谢途径是植物主要代谢途径之一,可产生黄酮、酚酸和木质素类等物质,这些物质不仅参与调控植物生长发育和抗逆等生理活动,还被用于预防和治疗疾病,是决定药用植物品质的关键因素之一。苯丙氨酸解氨酶(Phenylalanine ammonia-lyase,PAL)负责催化苯丙烷类代谢途径中第一个反应,是该途径的关键酶和限速酶。本文就药用植物中PAL基因的基本特性、表达调控机制等方面的研究进行综述,为进一步阐明药用植物中PAL的功能提供参考。
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.
