摘要: A total of 115 endophytic bacteria were isolated from root nodules the wild legume Sphaerophysa salsula grown in two ecological regions Loess Plateau China. The genetic diversity and phylogeny strains revealed by restriction fragment length polymorphism sequencing 16S rRNA gene enterobacterial repetitive intergenic consensus-PCR. Their symbiotic capacity was checked nodulation tests analysis nifH sequence. This is first systematic study on associated with S. nodules. Fifty found belonging to eight putative species genera Mesorhizobium, Rhizobium Sinorhizobium, harboring similar genes; Mesorhizobium gobiense main group 65 nonsymbiotic related 17 Paracoccus, Sphingomonas, Inquilinus, Pseudomonas, Serratia, Mycobacterium, Nocardia, Streptomyces, Paenibacillus, Brevibacillus, Staphylococcus, Lysinibacillus Bacillus, which universally coexistent Differing other studies, present time that have been simultaneously same nodules, offering possibility accurately reveal correlation between these kinds bacteria. These results provide valuable information about interactions among bacteria, their habitats.
