Abstract:

代谢组学作为系统生物学的重要分支,近年来在植物研究领域受到广泛关注,并取得了重要进展。植物代谢组学目前虽然是一个并不成熟的领域,但是在研究模式植物的生理生化过程和基因改造等方面已成为最为有效的手段之一,近年在研究非模式植物方面特别是药用植物方面也取得了突破性进展。作者在总结植物代谢组学的定义和发展的基础上重点阐述了其最新应用,并提出了植物代谢组学可能的发展方向。植物代谢组学为植物研究提供了一个整体全面的分析平台,从宏观角度更加科学地理解植物生理生化过程,进而为人类所用提供了可能。许多植物代谢物是中药的活性成分,其种类和含量随品种、生长环境、采集季节以及炮制方法等因素而变化。因此,中药的质量问题主要就是植物代谢组的问题。由于环境因素、植物有效部位对中药药效(或价值)有一定影响,而代谢组学法可以有效检测这些因素,植物代谢组学为深入研究开发中药资源创造了新的研究平台。
