Heat maps showing percentage of shared genes between phages infecting the same bacterial host species. (A) Cyanophages isolated on Prochlorococcus or Synechococcus, (B) E. coli phages, and (C) P. aeruginosa phages. Dashed lines separate Prochlorococcus and Synechococcus phages. Squares enclose phages belonging to the same phage family: I, Inoviridae; L, Leviviridae; M, Myoviridae; Mi, Microviridae; P, Podoviridae; S, Siphoviridae; T, Tectiviridae. Dark areas (large proportion of genes shared) outside of family squares indicate putatively horizontally transferred genes.
