烟草甾醇合成代谢分子调控研究进展

Advances in the Molecular Regulation of Tobacco Sterol Biosynthesis Metabolism

烟叶中的甾醇在卷烟燃烧过程中生成致癌物-多环芳烃(PAHs)。笔者主要阐述了植物甾醇在卷烟减害研究、调控植物生长发育和响应植物胁迫中的作用,重点介绍了植物甾醇合成代谢途径以及该途径中的关键酶基因。

Plant sterols in tobacco leaves can generate the carcinogen - polycyclic aromatic hydrocarbons （PAHs） in the combustion process of cigarette. In this article, the roles of plant sterols in tobacco harm reduction research, the regulation of plant growth and development, and the response to plant stress were primarily discussed, and the plant sterol biosynthetic pathway and key enzymes in this pathway were mainly introduced.
