白藜芦醇合成酶基因在基因工程中的应用及功能研究进展

Advances of resveratrol synthase gene in the application of genetic engineering and biofunctional investigation

白藜芦醇合成酶(Resveratrol synthase,RS)是白藜芦醇(Resveratrol,Res)合成途径中的关键酶。以往研究报道,RS基因已在多种植物和微生物中进行了转化和表达,并在植物的代谢及调控等方面发挥生物学作用。文中主要围绕RS基因对植物的转化,及异源表达后植物体内代谢产物的变化,转RS基因对植物抗病原菌活性、抗自由基活性和生长发育的影响,以及利用RS基因在微生物中生产Res的相关进展进行了综述。并对RS基因在生物工程方面的应用前景进行展望。

Resveratrol synthase （RS） plays a key role in resveratrol （Res） biosynthesis. RS gene has been formerly reported to be transformed into many plant species and microorganisms, and to play certain roles in metabolic and regulation processes. In this paper, the transformations of RS gene in plants, and the related changes of biological properties, such as metabolites, anti-pathogen activities, anti-radical properties, and developmental characters in transgenic plants, as well as the production of resveratrol in microbes by utilizing RS gene were summarized. Moreover, the application prospects of RS gene in bioengineering were also addressed.
