FIG 1.

Neighbor-joining tree (10) for Saccharibacteria (TM7) bacterium HMT 955 strain PM004. The tree was produced from aligned full-length 16S rRNA sequences (∼1,450 bp) using MEGA X (11). The designations in square brackets are the TM7 class level groups as described in reference 12. GenBank accession numbers for 16S rRNA or genome sequences are given in curly brackets. The scale bar shows a 5% difference in sequence similarity. For trees showing broader TM7 diversity, see references 12, to ,14.
