摘要:

次生代谢产物的生物学作用被认为是高等植物生存和进化的关键。类异戊二烯(Isoprenoids)化合物作为植物中极为丰富的一类次生代谢物,在植物信号转导、适应气候、繁殖及防御等方面具有多种生理功能。此外,植物类异戊二烯化合物还广泛应用于制药、天然乳胶、香料及有机合成等工业领域,具有重要的经济价值。异戊烯基转移酶(Prenyltransferase,PT)是连接上游甲羟戊酸和磷酸甲基赤藓糖途径与下游不同结构类异戊二烯生物合成分支点的关键酶,因此异戊烯基转移酶及其基因在整个类异戊二烯生物合成与调控过程中具有重要地位。本文介绍了植物类异戊二烯生物合成通路、异戊烯基转移酶基因克隆与分析、酶功能鉴定及其系统分类,并介绍了其在针叶树中的研究进展,旨在为植物类异戊二烯化合物生物合成与调控机制的进一步研究提供帮助,同时为针叶树种产脂和抗生物逆境的分子水平研究指明相关方向。

Abstract:

The biological role of secondary metabolites is recognized as the key to the survival and evolution of higher plants. Isoprenoids compounds,as a very rich class of secondary metabolites in plants,demonstrate various physiological functions in plant signal transduction,climate adaptation,reproduction and defense. In addition,plant isoprenoids compounds are also widely used in pharmaceutical,natural latex,perfume,organic synthesis and other industrial fields,with important economic values. Prenyltransferase(PT)is a key enzyme that connects the upstream mevalonate-independent and methyl-erythritol 4-phosphate pathway with the downstream branch points of isoprenoids biosynthesis of different structures. Therefore,prenyltransferase and their genes play an important role in the process of isoprenoids biosynthesis and regulation. This article introduces the biosynthesis pathway of isoprenoids in plants,prenyltransferase genes cloning and analysis,function identification of enzymes and systematic classification,and also introduces research progress in conifers. The aim is to provide assistance for the analysis of plant isoprenoids biosynthesis and regulatory mechanisms,and to point out some molecular research fields on producing rosin and biological adversity resistance of conifers.
