FIG. 2.

Genetic variability of PERV-A and -B proviruses. (Top) The three germ line proviral sequences A130, A151 (8,291 nt), and A463 as well as the prototype cell line-derived PERV-A sequence Ap60 were analyzed by LOHA (aligned into 8,356 positions). (Bottom) The three germ line proviral sequences B192, B213 (8,215 nt), and Bimut (8,217 nt) as well as the prototype cell line-derived PERV-B sequence Bp17 (8,256 nt) were analyzed (aligned into 8,253 nt positions). All six possible homology plots (0, 20, 40, 60, 80, or 100% was subtracted from percent match values as indicated [y axis]) for each set of sequences are shown.
