花香的生物合成、调控及基因工程研究进展

Adavances in Biosynthesis,Regulation and Genetic Engineering of Floral Scent

花香能提高观赏植物的审美特性,并且在植物的繁衍中起着重要作用。近年来,随着分子生物学的发展,花香分子水平的研究呈现加速发展的趋势,已成为当前的一大研究热点。该文主要论述了花香的生物合成途径及关键酶基因、分子水平的调控和共调控探索、花香基因工程策略,以期为花香性状改良提供参考。

Floral scent can enhance the aesthetic properties of ornamental plants and play an important role in their reproductive processes. With rapid development of molecular bio-technology, the researches of floral scent at molecular level which show a quickly advancing tendency have been becoming a hot project in recent years. In order to provide reference for the floral scent improving, this review describes biosynthesis of floral volatiles, re- lated enzymes/genes, molecular regulation and co-regulation, and strategies of genetic engineering.
