Genetic diversity in recombinant segments. A) For each homologous segment (quartet; regardless of evidence of recombination), we calculated the nucleotide diversity phi (Y axis; see Methods). The dots indicate the distribution means and the bars represent the 95% confidence intervals. Blue and red dots indicate recombinant and non-recombinant segments, respectively. Moreover, we determined the nucleotide diversity of the sequence regions shared across all of the tested strains of R. etli (green dot). Abscissa: BRASIL5, CIAT894, GR56, IE4771, KIM5, 8C-3 and shared regions. B) Magnification of the results from the 240 common sequence segments shared by all tested strains. The average percentage of SNPs was 12.89% per segment. The sphere sizes indicate the proportions of ts/tv for both recombinant segments (red circles) and non-recombinant segments (blue circles). The Y axis denotes the SNP percentage by gene segment, while the X axis shows the nucleotide diversity.
