ASLV genomic organization and target sites for primers used in this study. This diagram represents the generic organization of ASLV viruses for the gag (blue) pol (green) and env (grey) genes and their respective subunits for proteins p19, p2, p10, p27, NCp12, PRp15, reverse transcriptase, integrase and gp85. Target sites for the primers are indicated by green triangles, dark green for forward and light green for reverse primers. The U1, U2 and P27 primer sets detect all viral subgroups, while the E primer set binds only to viruses of the E subgroup. Since differences exist between viral subgroups and even within members of the same subgroup this diagram is not drawn to scale.
