Phylogenetic analysis of the five draft genomes within Chloroflexi phylum. Maximum-likelihood tree based on concatenated alignment of 35 essential single-copy genes (ESCGs) conserved in a single-copy manner among five curated genomes retrieved and twenty-two finished genomes within Chloroflexi phylum. Default protein model of Phyml 3.1 is used to construct the tree with 100 bootstraps based on MUSCLE alignment. 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
