Fig. 4: Gene phylogeny of Heimdallarchaeal viruses and other mobile elements.
a–d, Maximum-likelihood analyses showing the evolutionary relationship between the proteins encoded by the viral-like mobile elements HeimV1 and HeimV2 (bold black, marked by a blue star) with known viruses (magenta), bacteria (green), archaea (blue) and sequences from the Pescadero and Guaymas Basins metagenome assemblies (black). Highlighted with blue backgrounds are viruses with identified hosts. Bootstrap values are listed. The numbers of proteins selected for the phylogenetic analyses are 172 (a), 142 (b), 285 (c) and 87 (d). The serial numbers of the microbial and viral genomes are indicated in the figures and source data files. e, Schematic representation of the 56 contigs from the mobile elements targeting Heimdallarchaea mapped to the closest known homologues in bacteria (pink), archaea (teal) or viruses (purple) through protein orthologue analyses using eggNOG v.5.0. MGE contigs are ranked by size from large (44 kbp) to small (2.8 kbp) and concatenated. The percentages of each taxonomic group measured in the total gene lengths are indicated.
