Distribution of SNP’s over the ITS2 secondary structure. (a) ITS2 haplotype “H1” and (b) the Helix IV of the folded ITS2 haplotype “H3”. Arrows point bases at which natural variation was observed. Numbers in black are the bases numbering from the 5′end. The letters next to arrows are the alternative bases, i.e. SNP; bracketed numbers are instances among fourteen recorded haplotypes. SNP are colored in red, when a polymorphism is only found in I. cavalcantei; in blue for I. marabaensis; in purple, when shared between the species.
