Fig. 1From: Structural patterns of selection and diversity for Plasmodium vivax antigens DBP and AMA1Population structure of PvAMA1 and PvDBP RII sequences. Maximum-likelihood phylogenetic trees are shown for PvAMA1 (a) and PvDBP Region II (b). Leaves are coloured according to the geographic location for each strain. The location of the Sal-1 reference strain is also indicated on each figureBack to article page
