Phylogenetic tree of Mollicutes 16S rRNA.

The phylogenetic tree was constructed using Maximum Likelihood, including a total of 312 sequences representing Mollicutes taxa. Scorpion sequences are in bold. Red collapsed regions indicate 12 sequences reported in this study from H. arizonensis and S. mesaensis. For an expanded version of this figure see S2 Fig.</p

Phylogenetic tree showing species-specific clades for telson bacteria isolated from <i>S</i>. <i>mesaensis</i> and <i>H</i>. <i>arizonensis</i>.

A Maximum Likelihood phylogeny was constructed based on the DNA sequences of 114 16S rRNA samples isolated from S. mesaensis (n = 32) and H. arizonensis (n = 82) telsons. Scorpion-specific clades are identified by vertical bars numbered 1–12 with samples from H. arizonensis indicated in black; S. mesaensis indicated in red. We considered clades to be scorpion-specific if they contained 3 or more taxa from a single scorpion species and were supported by bootstrap values greater than 70.</p
