Fig. 5 in Plastid phylogenomics of the Eriostemon group (Rutaceae; Zanthoxyloideae): support for major clades and investigation of a backbone polytomy

Fig. 5. Results of the likelihood-mapping analysis of loci. (a) Plot of phylogenetic informativeness of individual loci, where a higher percentage of fully resolved quartets for a locus indicates greater support for tree-like evolution. Dashed lines on the plot indicate the three cut-off values that were tested for potentially improving phylogenetic resolution of the polytomy (i.e. 50, 60 and 70%). Bars along the x-axis denote the cluster that each locus was placed in during the analysis of tree space; some loci were excluded from the tree-space analysis, owing to incomplete representation of samples. (b) Phylogenetic network (NeighborNet) showing splits of the backbone polytomy; constructed from a concatenated alignment of all loci with>60% of quartets fully resolved. For Crowea, EA, eastern Australia; WA, western Australia.
