植物内生放线菌作为植物内生菌资源的一大类，具有丰富的多样性，其次级代谢产物也十分丰富，而且还具有各种生物学活性。通过了解植物内生放线菌资源的多样性，可以对其产生的生物活性物质进行筛选和分析，从而筛选出具有良好药理活性的物质应用于临床。从植物内生放线菌宿主植物、组织分布、种类和数量以及活性基因4个方面综述了植物内生放线菌的多样性资源，介绍植物内生放线菌新的微生物物种，总结了植物内生放线菌目前研究中存在的问题及展望。

Endophytic actinomycetes display abundant diversity and have a capacity to produce a huge number of sec-ondary metabolites exhibiting a broad variety of biological activities as a kind of endophyte resources.Biological activi-ties produced by endophytic actinomycetes are screened and analyzed via understanding the biodiversity of endophytic actinomycetes resources so that favorable pharmacological active substances were screened for clinical diseases.Re-cently, with the development of researches about endophytic actinomycetes, many novel microorganism species were reported.This review focuses on diversity resources of endophytic actinomycetes from four aspects:host plants of en-dophytic actinomycetes, distribution in host plants tissue, species and number diversity and active gene and introduces the researches of novel endophytic actinomycetes species.Finally, this article summarizes the problems of endophytic actinomycetes at present researches and gives the possible further research direction.Endophytic actinomycetes which are emerging microbial resources have an important effect on science researches and progress of mankind.
