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.

Key words: isoprenoids, biosynthesis, prenyltransferase, gene family
