Maximum-likelihood phylogeny of an alignment of conserved regions of coding sequences from available whole genome sequences of mammalian type C leukemia retroviruses. Porcine endogenous retrovirus (PERV, accession AF038600), M. dunni endogenous retrovirus MDEV (AF053745), koala endogenous retrovirus (7) (KoRV, AF151794), Gibbon ape leukemia virus (GALV, M26927), gibbon ape leukemia virus strain X (GALVX, GLU60065), feline leukemia virus (FELV, M18247 and M19392), murine leukemia virus (MLV, MLU13766), Friend murine leukemia virus (FMLV, M93134 and M81185), rat leukemia virus (RLV, MLVGAG), Moloney murine leukemia virus (MMLV, REMLM). Sequences were aligned by eye; positions too variable to be confidently aligned were excluded from the analysis, leaving a final alignment of 4,779 bp. We assumed an HKY+Γ model, with transition-transversion ratio (ti/tv), (ti/tv) base composition, and gamma shape parameter (α) estimated from the data) (ti/tv = 3.1, α = 0.4). Scale in substitutions per site.
