Scatterplots of pairwise evolutionary distances between the combined 16S-23S rRNA (x-axis) and (A) ThrRS and (B) SerRS sequences on y-axis from a diverse sampling of bacteria. In (A), distances between taxa within the ThrRS-R clade (plotted in red) show a strong correlation with the rRNA distances (R2 = 0.90, P < 2.2 × 10-16), as do the distances within the ThrRS-C plotted in green (R2 = 0.98, P < 2.2 × 10-16). Pairwise distances for Aeropyrum pernix and Ignicoccus hospitalis were not included in the scatterplot because of the high rate of sequence divergence (long branches in Figure 2B). A strong correlation between the pairwise distances is expected for two trees with similar topologies. In (B), the distances for each clade show a strong correlation with the rRNA distances. Distances with the SerRS-R are plotted in red (R2 = 0.94, P < 2.2 × 10-16) and SerRS-C in green (R2 = 0.95, P < 2.2 × 10-16). Pairwise distances between each clade are shown in blue.
