Maximum likelihood phylogenetic trees of major viral families harboring replication-associated proteins (Additional file 1 : Table S4). The name of the viral family is shown above each tree. The solid black circles on each branch node represent bootstrap values above 50. The tip nodes on each tree represent an average of 95% nucleotide identity (vANI95) representatives identified in the present study, with the color indicating the host genus and the shape representing the host order, as listed in the bottom panel.
