Phylogenies of exported P. falciparum proteins and orthologs. Sequence trees were inferred using a Bayesian approach; Bayesian posterior probabilities are given at the nodes and scale bars are equal to 0.1 substitutions per site. Putative PEXEL sequences are given next to each species (shaded in grey). Presence of a preceding hydrophobic signal sequence is indicated by a black box; absence (due to missing or incorrectly annotated N-terminal sequence data) is indicated by a grey box. Note that only proteins with confirmed export in P. falciparum are shown. Abbreviations: Pfa, P. falciparum; Pre, P. reichenowi; Pga, P. gallinaceum; Pkn, P. knowlesi; Pvi, P. vivax; Pch, P. chabaudi; Pyo, P. yoelii; Pbe, P. berghei. See also Additional file 8.
