Distance tree of ATS domains of 3D7 PfEMP1 generated using the p-distance/NJ method. Though A, B and C clusters were vaguely supported by the bootstrapping, they were supported by maximum parsimony tree making. Numbers at the nodes represent bootstrap proportions (BP) on 1000 replicates. The scale bar represents the proportion of different amino acids compared. PlasmoDB accession numbers are shown. Genes with assigned cluster are collected in figure 7.
