[Methods] The root of P.dindygulensis Miq. was taken as materials,culture-independent method was applied to build 16 S rDNA clone library for endophytic bacteria of P. dindygulensis Miq. [Results] In the 16 S rDNA clone library for endophytic bacteria of P. dindygulensis Miq.,95 clones separately belonged to 46 OTUs,Phylogenetic analysis indicated that these cloning sequences separately belonged to phylum Proteobacteria,phylum Bacteroidetes,phylum Actinobacteria,phylum Nitrospirae,and phylum Gemmatimonadetes. In these,phylum Proteobacteria accounted for 70. 53% of total number of clones,so it was the most dominant group in this library. [Conclusions]The endophytic bacteria diversity in the root of P.dindygulensis Miq. is rich and this study is expected to provide scientific basis for protection,development and use of resources of P. dindygulensis Miq.展开更多
