Aligned amino acid sequences of Plasmodium gallinaceum (Pg), Plasmodium relictum lineage SGS1 (Pr) and Plasmodium falciparum (Pf). Bars on top represent amino acid similarities: green: 100% identity, brown >30 < 100%, red <30% similarity. Blocks 1–17 are assigned according to Tanabe et al.  [compare Table 1 legend], blue: conserved, white: repetitive region; red, variable and green: semi-conserved region. Amino acid similarity (%) for the different block; solid line with filled circles: P. relictum (SGS1 vs GRW4), solid line with open circles: P. gallinaceum (Pg) vs P. relictum (SGS1) and dashed line with X: P. falciparum MAD20 isolate (X05624.2) vs K1 isolate (X03371.1).
