Fig. 3.— — Examples of maximum likelihood trees congruent with EGT from an algal endosymbiont, but the algal type could not be determined. (a) Plastid terminal oxidase. (b) Chlorophyll synthetase. Numbers at nodes represent bootstrap proportion; only values higher than 60% are shown. For clarity, only the relevant taxa are shown (complete taxon list is available in Supplementary Material online); branches and taxa are colored according to their taxonomy: dark blue: C. velia; red: red algae; green: viridiplantae; orange: stramenopiles; light blue: haptophytes, cryptophytes; brown: Rhizaria; turquoise green: glaucophytes; black: prokaryotes, animals, fungi, Amoebozoa. All trees congruent with an algal origin are found in supplementary figure S4 (Supplementary Material online).
