Identification and Phylogenetic Analysis of the Complete Chloroplast Genomes of Three Ephedra Herbs Containing Ephedrine

Figure 6

Sliding window analysis of the whole CP genomes. Window length: 800 bp; step size: 200 bp. X-axis: position of the midpoint of a window. Y-axis: nucleotide diversity of each window. Pi amongst three Ephedra species. Mutational hotspots and highly divergent loci were marked.
