Figure 2.

Presence and distribution of enzymes in the Phycodnaviridae family. Representatives of each genus were included and data on the diversity and abundance of enzymes grouped into different functional categories were obtained from genomic annotations publicly available on GenBank. A network graph was constructed using Gephi 0.9.7 using a force-based algorithm (ForceAtlas2), followed by a manual arrangement of nodes for better visualization. Node sizes are proportional to the degree of connection. The thickness of the edges is proportional to the number of genes of the same function in the genome of a virus. Virus representatives: (1) Paramecium bursaria chlorella virus 1; (2) Emiliania huxleyi virus 86; (3) Feldmannia species virus; (4) Ostreococcus tauri virus 5; (5) Phaeocystis globosa virus; (6) Heterosigma akashiwo virus 01. Full data are available in Table S1.
