Fig. 4.

Maximum likelihood (ML) phylogeny of select alveolates based on 221 protein orthologs (all found in >60% of analyzed taxa). The dotted branch shows the placement of Abedinium dasypus in an alternate analysis including this taxon, which was excluded here due to relatively poor coverage of its transcriptome. Numbers at nodes represent bootstrap values over posterior probabilities; values of 100 and 1 are indicated with a black dot (all Bayesian posterior probability values are 1). In three out of four independent runs, Bayesian analysis predicted that Noctiluca scintillans branches with Amphidinium carterae (leaving the placement of Abedinium unaffected), but the topology was otherwise identical to that shown. The scale bar provides reference for the estimated number of amino acid substitutions per site.
