Maximum likelihood (RAxML) tree of the 'red lineage' proteins found in euglenids. The results of bootstrap analyses using RAxML (upper) and the Bayesian inference posterior probability values using MrBayes (lower) are shown on each branch. A, the best tree of the homogentisate phytyltransferase (HPT) family proteins shows that the E. gracilis HPT is closely related to the Chromalveolata and red algal homologues. B, the 'red lineage' genes encoding prokaryote-type ADP/ATP transporter have been found in euglenids and Chromalveolata. Thick branches represent BI and ML values not lower than 100 and 95, respectively. Eu, euglenids; CR, Chromalveolata plus Rhizaria; Red, red algae; Cyano, cyanobacteria. See supplementary figures for full trees.
