Proteome-based eukaryotic phylogeny (adapted with permission from Eichinger et al. [6]). The phylogenetic tree was constructed from a database of 5279 orthologous protein clusters that were drawn from 17 eukaryotic proteomes, including that of Dictyostelium discoideum, which was rooted on 159 protein clusters that had representatives from six archaebacterial proteomes: Plasmodium falciparum, malaria parasite; Chlamydomonas reinhardtii, green alga; Oryza sativa, rice; Zea mays, maize; Fugu rubripes, fish; Anopheles gambiae, mosquito.
