摘　　要：硫苷是十字花科Cruciferae植物中一类富含氮硫的次生代谢物,硫苷合成途径,特别是硫与硫苷合成关系的研究取得了很多进展。从硫苷核心结构形成过程中还原硫供体来源、活化硫酸盐来源以及半胱氨酸(Cys)、谷胱甘肽(GSH)和高能硫供体3′磷酸腺苷5′磷酰硫酸(PAPS)等初生硫代谢产物与硫苷合成间的关系等方面对硫苷合成过程中硫来源的研究进展进行了综述,提出GSH等初生硫代谢调控因子、氮硫等营养元素之间的平衡以及葡萄糖等信号分子对硫苷生物合成的调控机制将成为新的研究热点,以期为硫苷的生物合成调控研究提供理论依据。Glucosinolates are nitrogen-and sulfur-containing seconda ry metabolites that mainly found in the Brassicaceae plants. In recent years, the study which involves the biosynthesis of glucosinolates, especially its relationship with sulfur has made some new progress. The research attempted to review the research progresses on the sources of reduced sulfur and active sulfate in the formation of the core glucosinolate structure. The paper also discussed the link between primary sulfur metabolites including Cys, GSH, PAPS and glucosinolate biosynthesis, as well as the relevant research in the future, so as to lay the foundation for the further study.
