摘要

咖啡碱等嘌呤生物碱分布于自然界多种植物中,由于过量摄入咖啡碱会对人体产生副作用,因此对嘌呤碱代谢进行调控,培育低咖啡碱植物品种具有重要的意义。本文综述了嘌呤生物碱在不同属种植物中的分布、生物合成与降解的主要路径及非主要路径、参与嘌呤碱代谢的酶及相应编码基因克隆的研究进展,并对培育低咖啡碱茶树品种中存在的问题与今后的努力方向进行了讨论和展望。

Abstract

Purine alkaloids (e.g. caffeine) can be found in many plants. As excessive intake of caffeine could have side effects on human health, it would be of great significance to obtain a low caffeine level cultivar by regulating metabolism of purine alkaloids. The present paper summarized the distribution, biosynthesis and catabolism (including main and minor pathways) of purine alkaloids, then enzymes and cloning of related genes involved in metabolism of purine alkaloids in tea and other plants. Finally, the exiting problems and possible ways of breeding low caffeine tea cultivars are discussed.
