摘　　要：植物内生菌是一个多样性十分丰富的微生物类群,分布于没有外在感染症状的健康植物组织内。随着研究领域的不断拓宽和研究方法的不断深入,越来越多的植物内生菌被分离出来,并从这些内生菌的代谢产物中发现了很多重要的生物活性物质。本文综述了不同种类的内生菌的分布和分离方法,以及植物内生菌次级代谢产物的生理作用及其在抗菌、抗虫、抗肿瘤等方面的应用研究进展。Endophyte is a very rich diversity of microbial taxa,it is distributed in healthy plant tissues which have no external symptoms of infection.With the constantly expanding field of study and the continuous deepening of researching methods,more and more endophytes are isolated.Many important bioactive substances have been found through the metabolites of endophytes.The research advances in isolation methods of various endophytes are summarized in this article.The ecological and physiological role and applications in the antibacterial,insect resistance,antitumor of endophytic secondary metabolites are introduced simultaneously.
