FIG 2.

Comparative genomics of major families Myoviridae (Kochiodavirus and Schiekvirus genera) and Siphoviridae (Saphexavirus genus). (A) Phylogenetic tree made from the core genome of Siphoviridae phages. (B) Number of genes in the Siphoviridae core genome and average number ± standard error of the mean (SEM) of accessory genes per phage genome. (C) Layout of genes in a representative Siphoviridae genome (phage SDS1), with known genes annotated. Colors indicate numbers of other phages that also contained each gene (50% BLASTp similarity). (D) Phylogenetic tree made from the core genome of Myoviridae phages. (E) Number of genes in the Myoviridae core genome and accessory genome per phage. (F) Layout of genes in a representative Myoviridae genome (phage phiV12) with known genes annotated. Colors indicate numbers of other phages that also contain each gene (50% BLASTp similarity).
