Network of evolutionary connections between mavericks, virophages, and other viruses and capsidless elements. Bacteriophage groups that are involved in the network connections are as follows: Tectiviridae (PolB), Caudovirales (tailed bacteriophages) (S3H and GIY-YIG), and cyanophages (MV19 peptidase). Groups of NCLDV that are involved in the network connections are as follows: irido-, mimi-, pox-, and marseilleviruses (mavirus S3H helicase); marseillevirus (OLV S3H helicase and MV19 peptidase); Phaeocystis globosa virus and invertebrate iridescent virus 6 (GIY-YIG); Phycodnaviridae (Tir 6F); Poxviridae and Asfarviridae (ATPase), and Mimiviridae (MV20 FNIP repeats).
