植物花香代谢调节与基因工程研究进展

Research Advances in Metabolic Regulation and Genetic Engineering of Floral Scent

摘要:

植物花香在吸引昆虫授粉、提高观赏价值和香精的商业价值方面具有重要的作用。随着分子生物学技术的发展,近年来植物花香基因被大量克隆,对花香化合物的合成与代谢的网络调控机制有了更深刻的认识,基因工程改良花香成为可能。对近年来植物花香的合成途径、花香的释放与基因调节、基因工程的研究进展进行了综述,并就存在的问题进行了分析,为花香的分子育种研究提供参考。

Abstract:

Floral scent plays an important role in attracting insect pollinators and also enhances the economic value of ornamental plants and commercial value of perfumery. In recent years, with the development of molecular biological technology, especially many genes related to floral scent have been cloned, the regulation mechanism of biosynthesis and metabolism of floral scent compounds had be understood deeply, so that it was possible to change floral scents by genetic engineering technology. The advances in the biosynthesis path way, emission, and gene regulation of floral scent compounds were reviewed, and the strategies of changing floral scent by genetic engineering were discussed, and the molecular breeding of floral scent in the future was prospected.
