Fig. 3From: The impacts of polyploidy, geographic and ecological isolations on the diversification of Panax (Araliaceae)Topologies of Bayesian trees based on nrITS and seven single copy nuclear genes. Each branch represents one haplotype and identical sequences from the same species were removed. The color of branch stands for different species. Numbers of haplotypes for each gene were shown in Additional file 2: Table S2Back to article page
