Phylogenetic analysis using rbcL gene from 30 species with available chloroplast sequences in the Asteraceae. Taraxacum kok-saghyz, T. brevicorniculatum, and T. officinale are highlighted in red. The bar at the bottom shows the scale of the branch length representing the number of substitutions per site. Numbers shown next to the nodes indicate the percentage of trees with the associated taxa clustered together
