高等植物牻牛儿基牻牛儿基焦磷酸合成酶基因的研究进展

Research progress of geranylgeranyl pyrophosphate synthase gene in higher plants

牻牛儿基牻牛儿基焦磷酸合成酶(GGPPS)在植物体内催化牻牛儿基牻牛儿基焦磷酸(GGPP)的合成,GGPP是萜类物质、类胡萝卜素、叶绿素及几个重要植物激素合成的前体物,是联系植物体内多条重要次生代谢通路的节点物质。本文综述了植物GGPPS基因近年来的生物学功能研究进展和该基因家族的遗传分类情况,以及GGPPS小亚基基因的重要调控作用,拟为深入研究植物GGPPS基因的生物学功能和萜类含量调控的遗传工程提供新认识和新思路。

In plants, geranylgeranyl pyrophosphate synthase（GGPPS） catalyzes geranylgeranyl pyrophosphate（GGPP） synthesis, which is the precursor of terpenoids, carotenoids, chlorophylls and several vital plant hormones, and also an important node in some secondary metabolic pathways. In this review, we summarize the research progress of plant GGPPS in recent years, focusing on biological functions of plant GGPPS genes, genetic classification of GGPPS gene family, and significant regulation roles of GGPPS subunit genes. This article could provide new insight and thought for further revealing biological functions of GGPPS genes and genetic engineering of terpenoids.
