Individual Pfcytb polymorphisms and allelic types observed in the study areas. WT : wild type ; * non synonymous mutation; ° synonymous mutation. The polymorphic sites observed in this study are shown by codon (numbers refer to positions in the protein sequence). Amino acids are indicated with single letter code and in capital, the nucleotide changes are indicated below (bold). Area-specific mutations are coloured in brown, blue and orange for Ivory Coast, Cambodia and French Guiana, respectively. In grey, T42T, the only mutation found common between two settings.
