PhyML phylogenetic trees of the RNA polymerases (A), DNA polymerases (B), and major capsid genes (C) of the phages of the Autographivirinae. Red lines indicate the clade of “phiKMV-like viruses”; blue lines, the “SP6-like viruses”; and green lines, the “T7-like viruses.” The unassigned Autographivirinae are indicated by black lines, as are Siphovirus phage Xp10 and Ralstonia phage RSB1, which do not cluster in any of the previous groups.
