Figure 3. ML tree showing the phylogenetic relationship of five Dichocarpum taxa and four outgroup taxa, which is inferred based on 27 one-to-one single copy orthologs.

The model of nucleotides substitution is HKY85, and four classes are used in the discrete Gamma model. The bootstrap values are obtained using the default “approximate Bayes branch supports” in PhyML 3.0. The scale bar represents the number of base substitutions per site.
