Unrooted phylogenetic tree of nearly full-length 16S rRNA gene sequences showing the relationships among the endophytic diazotrophic bacteria isolated from highland rice landraces tissue and related genera. Bootstrap analysis was based on 1,000 replicates. Neighbor Joining tree and the scale bar present 0.01 nucleotide substitutions, where the accession numbers of the sequences are indicated in parentheses
