【摘要】 合成生物学是解析中药活性成分生物合成途径、发掘参与生物合成功能基因的一门新兴学科。柴胡是我国常用大宗中药材,药用价值显著。柴胡皂苷是其指标性成分,具有抗炎、抗病毒、抗肿瘤等显著活性。但目前野生柴胡资源遭到破坏,人工栽培过程中存在一定问题。生物培养技术及合成生物学的应用可扩大柴胡皂苷的来源,保护柴胡资源。不同植物的培养条件没有固定模式可遵循,不同药用活性成分的生物合成途径也是不一致的。目前,尚无柴胡组织培养技术及柴胡皂苷生物合成途径研究的综述报道。该文拟介绍合成生物学过程中用到的愈伤组织培养、不定根培养、毛状根培养与悬浮细胞培养等生物培养技术与柴胡皂苷生物合成途径及其关键酶功能基因的研究进展,建议通过借鉴其他传统根类药材的组织培养技术,对柴胡的生物培养技术进行优化,为深入研究柴胡皂苷的生物合成途径与代谢调控提供参考。更多还原

【Abstract】 Synthetic biology is an emerging discipline that analyzes the biosynthesis pathways of active constituents in traditional Chinese medicine and explores genes involved in biosynthesis. Bupleuri Radix is one of the most commonly used Chinese medicinal materials with remarkable medicinal value,its index component is saikosaponins,which has significant anti-inflammatory,anti-viral and anti-tumor activities. However,the current wild resources of Bupleuri Radix have been destroyed,and there were some problems in the process of artificial cultivation. The application of biological culture technology and synthetic biology can expand the sources of saikosaponins and protect resources of Bupleuri Radix. The culture conditions of different plants can be followed without a fixed pattern,and the biosynthetic pathways of different medicinal active ingredients are also inconsistent.At present,there is no review report on the culture technology of Bupleuri Radix and the research on the biosynthesis pathway of saikosaponins. This paper introduces the research progress of biological culture techniques,such as callus culture,adventitious root culture,hairy root culture and suspension cell culture used in synthetic biology,and the biosynthesis pathway of saikosaponins and its key enzyme functional genes. It is suggested to optimize the biological culture technology of Bupleuri Radix by referring to the tissue culture technology of other traditional root medicinal materials,so as to provide a reference for the in-depth study on the biosynthesis pathway and metabolic regulation of saikosaponins.更多还原
