The conserved structure module arrangement of the T7 supergroup. Genomic segments of phages T7, VpV262, Pf-WMP3, and CW02 are shown. The division of the T7 supergroup (dashed line) is characterized by inverted directionality of the genes in T7 compared to the VpV262-like cluster, as discussed in reference 38. Numbering indicates base pair positions from the 5′ to the 3′ end of the coding strand. Scale bar, 1 kb.
