Possible recombinant regions in recombinant proviruses. (A) Sequences of possible recombination sites of type A Xeno/Poly, type C Xeno/mPoly, and mPoly/Xeno recombinant proviruses. (B and C) Recombination sites of type B Xeno/mPoly (B) and mPoly/Poly (C) recombinant proviruses. Nonecotropic provirus sequences are shown at the top and bottom. Only bases differing from those of at least one nonecotropic provirus are shown. The deduced recombination sites are indicated by arrows and correspond to the region indicated in Fig. 4. Sources of sequence data: xenotropic, NZB (37); polytropic, MX27 (42); modified polytropic, MX33 (42).
