Figure 2From: A single origin of the photosynthetic organelle in different Paulinellalineages(A) RAxML phylogenetic tree of nuclear 18S rDNA from Rhizaria with the root placed on the branch leading to the Foraminifera. (B) RAxML phylogenetic tree of a concatenated data set of plastid-encoded 16S + 23S rDNA with the root placed on the branch leading to Plantae plastids. The numbers at the nodes of both trees 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).Back to article page
