Distance tree of 3D7 RIFINs generated using the p-distance/NJ method. MAL6P1.251 was left out as it aligned closer to STEVORs in preliminary alignments (data not shown). Red dots mark RIFINs flanked by upsA-rif. Though, the tree topology could not be confirmed by bootstrapping, the clusters containing the marked RIFINs were verified by the maximum parsimony tree (not shown). The scale bar represents the proportion of different amino acids compared. No accession numbers are given to simplify the graphics.
