Model of Asgard viral infection mechanisms and protein similarity with other viruses: (a) genes identified in Asgard viruses involved in infection (i), replication (ii), transcription (iii) and translation (iv); Asgard viruses are shown as different colored hexagons, Asgard hosts as different colored circles, and host transcription machinery is labeled with ovals color coded by function (see legend); (b) distribution of 35 genes (lower x axis) among Asgard viruses (y axis); filled circles indicate annotated orthologues, while white circles indicate that an orthologue was not identified.
