Sliding window of omega values (ω = d
) for three members of the 6-Cys family expressed in merozoites. The ω values (dN/dS) for Plasmodium vivax pv12, pv38 and pv41 genes are shown in red, divergence (ω = KN/KS) between P. vivax and Plasmodium cynomolgi (Pcyn) in purple and between P. vivax and Plasmodium knowlesi (Pkno) in green. The graphical representation of each gene is given below the respective sliding window, showing the position of the segregant sites and which of them were influenced by natural selection. Intraspecies selected sites can be seen in the upper part of each gene and inter-species selected sites are indicated in the lower part. The sites were identified by the Datamonkey server. The schemes for pv12 and pv38 have been modified from Forero-Rodríguez et al. .
