Maximum likelihood (ML) phylogeny of rbcL gene sequences for Heterococcusand other members of Xanthophyceae. The phylogeny was calculated with the programme GARLI v0.96 [25,26] based on a rbcL data set (1325 bp long, 517/418 variable/parsimony informative sites) consisting of 15 Heterococcus and 32 other Xanthophyceae sequences (corresponding to clades C, B, T, and V as defined in [14]) as well as two sequences from Phaeophyceae as outgroup. Scale bar, substitution per site. Numbers mapped to internodes are bootstrap values from 2000 replicates, only values >70% have been recorded. The phylogeny in this Figure includes the phylogeny of 15 Heterococcus strains shown in Figure 3 (highlighted). The inserted table lists bootstrap values mapped to internodes of the Heterococcus clade using six different analysis methods (see text). Scale bar, substitution per site.
