Sequence divergence distribution along the amplified fragments. The values on the x-axis correspond to the nucleotide position of the fragment amplified. The values on the y-axis are the nucleotide diversity (Ï€) measure, the percentage of divergent nucleotides relative to the number of informative bases, calculated using a sliding window of 10 bp and a step of 1 bp, by the DnaSp program [31]. The position of the TATA box and U3 are indicated. Data are shown for all sequences amplified and for pair-wise comparisons within groups without gaps.
