From: Molecular and phylogenetic analyses of a new Amphotropic murine leukemia virus (MuLV-1313)
Evolutionary relationship between highly conserved MuLV pol genes. Dendrogram was constructed from a 576 bp region of the MuLV pol gene encoding the highly conserved domains 1 through 7 of the retroviral reverse transcriptase protein [67] by using the neighbor-joining method. No gaps were introduced in any of the respective sequences to maintain the final alignment. Horizontal branch lengths are drawn to scale. Sequences from 13 highly conserved regions of 13 viruses used in the analysis include: MuLV 1313 (AF411814), Cas-Br-E MuLV (X57540), AKV MuLV (J01998), Friend-57 MuLV (X02794), Friend FB29 MuLV (Z11128), Friend PVC211 MuLV (M93134), mink cell focus-forming virus 1233 (MCF1233, U13766), Moloney MuLV (J02255), radiation leukemia virus (RadLV, K03363), Rauscher MuLV (Rauscher, U94692), SL3-3 MuLV (AF169256) and solid-type reticulum cell sarcoma 19-6 MuLV (SRS 19-6, AF019230) and HEMV (AY818896). Comparison of highly conserved pol sequences also indicated that MuLV 1313 is distinct from all other MuLV strains and is related to Cas-Br-E MuLV.
