Fig. 2From: The human gut bacteria Christensenellaceae are widespread, heritable, and associated with healthPhylogenetic relatedness of Christensenellaceae. Full length 16S rRNA gene sequences were obtained from NCBI and aligned using MAFFT. Accession numbers for each sequence are provided in parentheses. Bootstrap values (> 50%) are expressed as a percentage for 100 iterations. A maximum likelihood tree was built using RaxML with a general time reversible evolutionary model, and B. thetaiotaomicron was selected as the outgroup for rooting the tree. The scale bar represents substitutions per siteBack to article page
