三七Notoginseng Radix et Rhizoma为五加科人参属的多年生草本植物，在我国已有近400多年的栽培历史。内生菌作为三七生态系统中的重要生物因素，在三七生长过程中具有重要作用。三七内生菌群结构类型丰富，次生代谢产物多样，且具有促进三七生长发育、提高抗性、诱导代谢产物合成或转化等作用，有望用于缓解三七连作障碍和提升三七品质等。通过对三七内生菌群的多样性、功能及应用、及其对三七代谢的影响等进行综述，为三七内生菌资源的有效利用提供参考。

Sanqi (Notoginseng Radix et Rhizoma) is a perennial herb of Araliaceae. It has been cultivated in China for more than 400 years. Endophyte, as an important biological factor in Notoginseng Radix et Rhizoma ecosystem, plays an important role during the life of Notoginseng Radix et Rhizoma. The endophytic flora of Notoginseng Radix et Rhizoma has rich structural types and various secondary metabolites, which can promote the growth and development of Notoginseng Radix et Rhizoma, improve resistance, induce the synthesis or transformation of metabolites. It is expected to alleviate the obstacles of continuous cropping and beneficial in improving the quality of Notoginseng Radix et Rhizoma. This review summarizes the recent data related to the diversity of endophytic flora, function and application of endophytes in the Notoginseng Radix et Rhizoma, and the effect of endophytes on the metabolism of Notoginseng Radix et Rhizoma, which provides referencefor the further development and effective utilization of endophyte resources of Notoginseng Radix et Rhizoma.
