16S rRNA gene phylogeny of the order Thermotogales. Sequences in bold are 16S rRNA genes from mesophilic environments (see Table 1). The tree is a ME tree estimated in PAUP* using LogDet distances. The ML tree estimated using a GTR + Γ + I model was similar, the main difference being the placement of the root of the order Thermotogales (indicated by an arrow). Numbers on branches indicate the percentage of occurrence in 100 bootstrap replicates using LogDet distances (plain) and ML (bold). If the support was at least 90% in both analyses, a black circle is given on the branch.
