植物萜类次生代谢及其调控

Biosynthesis and Regulation of Secondary Terpenoid Metabolism in Plants

植物次生代谢在植物生长发育、环境适应、抵御病虫害等方面发挥着重要作用,这些天然产物组成地球上最丰富的有机化合物的宝库.萜类是植物代谢产物中种类最多的一类,具有重要的生理和生态功能,一些成分还有应用价值.近十几年来,人们在萜类化合物的分离、鉴定、应用、生物合成、相关基因与基因族、酶蛋白结构和功能、代谢调控以及代谢工程等各方面取得了重大进展.本文概述了植物萜类化合物代谢及其调控领域的研究进展与发展趋势.

As the most diverse natural organic compounds, plant secondary metabolites play critical roles in regulating plant growth and development, facilitating environmental adaptation and defending against insects and pathogens. Terpenoids constitute one of the largest families of secondary metabolites, and have important physiological and ecological functions. Some of them even show great pharmaceutical values. In recent decades, great achievements have been made in isolation and characterization of terpenoids, elucidation of their biosynthetic pathways and regulation mechanisms, as well as genetic engineering. This review discusses recent progress in terpenoid metabolism and regulation.
