十字花科植物中主要硫代葡萄糖苷合成与调节基因的研究进展

Research Progress on Regulation and Synthesis Genes on Glucosinolates Biosynthesis in Crucifer

硫代葡萄糖苷(简称硫苷)是十字花科植物中的一类重要次生代谢产物,硫苷及其降解产物具有重要的生物活性。近年来随着对模式植物拟南芥基因组序列测定的完成和功能解析的进行,人们对硫苷的生物代谢途径有了较为深入的了解,硫苷合成的调控基因也成为研究热点,尤其是在硫苷合成不同阶段分别起着重要作用的MYB、MAM、CYP79/CYP83、AOP等基因家族。现就十字花科植物中硫苷的生物学功能、主要合成与调节基因等研究进展进行了综述,并对其在十字花科作物育种上的应用前景进行了展望。

Glucosinolates is a group of important secondary metabolites found in cruciferous plants. They and their degradation products have important biological properties.In recent years,with genome sequencing and functional analysis in model plant Arabidopsis thaliana,people understand more about metabolic pathways of glucosinolates.Its gene regulation and synthesis has become a research hotspot. Some gene families（such as MYB,MAM,CYP79/CYP83,and AOP）have played important roles in different stages of glucosinolate synthesis.The biological functions of glucosinolates and the regulating and synthesizing genes involved are reviewed and the prospect of their application in crucifer breeding is also discussed in this paper.
