摘要
植物内生真菌作为一类重要的微生物资源,不仅可在植物组织内生活且不引起植物病变,还能产生大量具有活性的天然产物。植物内生真菌多糖作为一类重要的大分子天然产物,越来越多证据表明其具有重要的研究价值。植物内生真菌的来源、培养和发酵,植物内生真菌均一多糖的理化性质和结构特征等都与其多糖的生理活性密切相关。为此,从菌株选择、培养条件、多糖分离纯化、理化特征、生物活性和对植物的作用等方面对植物内生真菌多糖的研究进行了综述,以期为植物内生真菌多糖的生理生化作用、开发等深入研究提供参考。
Endophytic fungi from plant,as an important microbial resource,not only can live in the internal tissues of plants without causing any symptoms,but also produce a large number of bioactive natural products.The polysaccharide(PS)produced by endophytic fungi derived from plant is one important kind of macromolecular natural products,and the research value of PS from endophytic fungi is confirmed by increasing reports.The source,culture and fermentation of endophytic fungi,the physical and chemical properties and structural characteristics of homopolysaccharides from endophytic fungi are closely related to their physiological activities.The strain selection,strain culture condition,polysaccharide separation and purification,physicochemical characteristics,biological activity and effects on plants of endophytic fungal PSs are summarized in this report,aiming to develop the endophytic fungal polysaccharides,and to provide some references for further research on the physiological and biochemical effects of endophytic fungal PSs,
