Abstract | Comparison of the genomic sequences of the Friend spleen focus-forming virus with other murine retroviral sequences indicated that the spleen focus-forming virus was derived from at least three retroviruses. The 5' end of the virus, from the primer binding site through most of gag, was derived from AKV. The rest of gag and all of pol were of uncertain origin, but were probably derived from the same xenotropic virus that gave rise to the 5' half of env. The remainder was derived from Friend murine leukemia virus. The positions of a 585-base deletion, a 6-base duplication, and a point insertion that leads to a frame shift and premature protein termination in the ecotropic 3' end of env were invariant between three spleen focus-forming virus strains, indicating that they had a single common ancestor. However, the point of crossover between xenotropic viral sequences and Friend murine leukemia virus was different in each strain, and two strains were much more closely related to each other than to the third in the xenotropic region, indicating that these strains had diverged by multiple recombinations. Furthermore, a different nucleotide comprised the single point insertion near the 3' end of env, suggesting that these viruses have an extremely high transition and transversion rate. |
