Phylogenetic analysis of the five draft genomes within Chloroflexi phylum. Neighbor-joining phylogenetic tree based on 16S rRNA gene. The tree is produced with neighbor-joining analysis based on ClustalW alignment. 16S rRNA gene sequences of Thermotogae are used to root the tree. Bootstrap value is obtained with the maximum-composite-likelihood methods based on 1000 replicates. Bootstrap values greater than 50 % are indicated at branch points. Branch labels are colored according to their categories (1) our five draft genomes in red; (2) complete genomes in purple; (3) isolated strains are in green
