摘要
萜类是植物中一类重要的次生代谢物,具有重要的生理生态作用及经济价值。萜类合成酶是萜类化合物形成的关键酶,包括单萜合成酶、倍半萜合成酶和二萜合成酶等,其种类和功能决定了萜类的多样性。萜类合成代谢具有明显的组织特异性,并受植物发育进程的调控,外界生物与非生物因子对其代谢有显著影响。基因工程技术在一定程度上改变了转基因植株中萜类的组分和含量。综述了近年来在萜类合成酶结构、分类和作用机理以及萜类代谢调控的研究进展。
Terpenoids are important secondary metabolites in plants,which have important physiological and ecological functions as well as economic values.The terpene synthases including monoterpene synthases,sesquiterpene synthases and diterpene synthases,are critical enzymes for the formation of terpenoids.The metabolism of terpenes is characterized with tissure-specificity,which is regulated by developments and by biotic and abiotic factors as well.In addition,the components and contents of terpenoids in transgenic plants can be altered,to some extent,by using genetic engineering.This review mainly summarizes the recent research progress in structure,classification and metabolism of terpene synthases.The regulation of terpene metabolism is also discussed.
