Figure 3.

RAxML phylogenetic tree of actin sequences from photosynthetic Paulinella spp. with the root placed on the branch leading to chromalveolate taxa (i.e., stramenopiles + alveolates). The numbers at the nodes show support values derived from a RAxML bootstrap analysis followed by those from a PhyML analysis. When both values are the same, then this is marked with an asterisk and when a node is not resolved with a method than this is denoted with dashes. Only bootstrap values ≥ 50% are shown. The thick branches have a Bayesian posterior probability > 0.95. Branch lengths are proportional to the number of substitutions per site (see scale bar).
