Research Advances in Metabolic Regulation and Genetic Engineering of Floral Scent
植物花香代谢调节与基因工程研究进展

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.
