| 中文摘要: |
| 植物中药功能基因研究主要是探寻中药活性成分相关功能基因及表达规律,确定药用成分合成的调控机制,获得中药药用成分关键代谢途径和其中的关键调控因子,为中药现代化奠定基础。本文从模式植物(水稻、拟南芥等)、主要技术策略(基因表达差异、基因表达序列标签、基因芯片技术和基因表达序列分析)和生物信息学方法(比较基因组学等)等三方面对国内外植物功能基因研究作了介绍。还介绍了黄酮类化合物与紫杉醇生物合成基因及植物P450基因研究现状。并对本研究室石斛碱功能基因研究情况作了简介。 |
| 英文摘要: |
| In order to establish the foundation for modernization of Chinese herbal medicine, discovery of the functional genes related with the bioactive components of Chinese herbs and the rules of their expression was progressed for determining the regulatory mechanism, obtaining the core metabolic pathway and key regulatory factors of the medicinal components synthesis. In this article, the studies about plant’s functional genes at home and abroad was introduced in three aspects: the pattern plants (rice, thaliana, etc. ), the main technologic strategy (gene expression differentia, sequential tag of gene expression, DNA microarray technique and gene expression sequential analysis) and bio-informative method (comparative genomics). The current status of researches involving biosynthesis genes of flavonoids compounds and taxol, and the plant P450 genes were introduced. And the study of dendrobium functional genes conducted in authors’ lab was also reviewed. |
