植物代谢组学研究进展

代谢组学是继基因组学、转录组学和蛋白质组学之后发展起来的一门学科，通过对细胞内的基因表达最终代谢产物的定性和定量分析以及定义细胞或器官的生化表现类型来解释功能基因的表达过程。文中就代谢组学的发展历史、主要研究内容、技术特点、数据处理过程及在植物领域中的应用的最新进展几方面进行阐述，以供读者参考

Artemisinin isolated from the aerial parts of Artemisia annua L. is a promising and potent antimalarial drug which has a remarkable activity against chloroquine-resistant and chloroquine-sensitive strains of Plasmodium falciparum, and is useful in treatment of cerebral malaria. Because the low content (0.01-1 %) of artemisinin in A. annua is a limitation to the commercial production of the drug, many research groups have been focusing their researches on enhancing the production of artemisinin in tissue culture or in the whole plant of A. annua. This review mainly focuses on the progresses made in the production of artemisinin from A. annua by biotechnological strategies including in vitro tissue culture, metabolic regulation of artemisinin biosynthesis, genetic engineering, and bioreactor technology.Artemisinin isolated from the aerial parts of Artemisia annua L. is a promising and potent antimalarial drug which has a remarkable activity against chloroquine-resistant and chloroquine-sensitive strains of Plasmodium falciparum, and is useful in treatment of cerebral malaria.

对水母雪莲细胞悬浮培养过程中细胞生长、黄酮积累和底物消耗的动力学过程进行了研究。经15d液体培养可获得最大生物量干重和黄酮产量分别为17．2g·L^-1和607．8mg·L^-1，通过调控基本培养基种类和有机添加物可提高雪莲细胞的生长和黄酮积累。获得的水母雪莲细胞培养物具有明显的抗氧化活性，其抗氧化活性与雪莲细胞中的黄酮含量相关
