Figure 6
Exomer component evolution across the tree of eukaryotes. The gains and losses of exomer components are mapped on this cartoon representation of eukaryotic lineages based on presence of at least two positive orthologues in a given taxonomic group. The purple circles indicate two instances where a single representative taxon possesses the ChAP protein despite multiple other representatives lacking the gene. In both cases (Toxoplasma gondii and Trichomonas vaginalis respectively), the organisms in question are known possess more canonical or expanded eukaryotic complements and have retained aspects lost in their relatives55,56. The double blue circle in the ascomycetes denotes the duplications giving rise to the expanded ChAPs complement, as detailed in Figs 2 and 3. The Fungi* represents the paraphyletic assembly of Holomycota, with Ascomycota treated separately due to the additional evolutionary detail relating to exomer. Relationships are based on57,58,59.
