The reconstructed evolutionary scenario for the Thermus-Deinococcus clade. LBCA – Last Bacterial Common Ancestor; DR-TT – the common ancestor of Thermus-Deinococcus clade; TT – T. thermophilus; DR- D. radiodurans. Total number of COGs is shown in boxes for each node. '+' indicates inferred gene (COG) gain, and '-' indicates inferred loss.
