Neighbor-joining analysis. Using MEGA 4.0 of the complete genome of isolates of the West and Central African alphasatellites and other alphasatellite isolates from GenBank. Horizontal lines are in proportion to the number of nucleotide substitutions per site. Numbers represent percent bootstrap values out of 2,000 replicates. The GenBank accession numbers of the nucleotide sequences of alphasatellites are indicated. The abbreviations are according to Briddon et al. .
