Fig. 5From: The size diversity of the Pteridaceae family chloroplast genome is caused by overlong intergenic spacersPhylogenetic relationship (right) and divergent time estimate (left) of the 41 Pteridaceae species. The mean divergence time of the nodes is shown next to the nodes while the blue bars correspond to the 95% highest posterior density (HPD). The red dots represent species within the branch that contain overlong IGS. Bootstrap value/posterior probabilities < 100%/1 are displayed on the branchesBack to article page
