(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).
