咖啡因生物合成研究进展及在茶树育种中的应用

Research Progress on Caffeine Biosynthesis and Its Application in Tea Breeding

咖啡因是一种嘌呤生物碱,存在于茶和咖啡中。由于咖啡因对一些人有引起失眠等的副作用,所以培育低咖啡因咖啡和茶树品种具有非常重要的意义。本文综述了近年咖啡因生物合成与代谢的研究进展,包括相关酶的基因克隆等。

Caffeine, a purine alkaloid, is a key component of tea and coffee. Breeding tea and coffee variety with low caffeine has important significance to avoid the short-term side effects of caffeine on human, such as insomnia. The recent research progress in caffeine biosynthesis and catabolism are reviewed in the present paper,and the possible approach to breed low caffeine tea and the existing problems are also discussed.
