Fig. 6From: Comparative analysis of the complete chloroplast genomes of six threatened subgenus Gynopodium (Magnolia) speciesSliding window test of nucleotide diversity (Pi) in the multiple alignments of six subgenus Gynopodium species (window length: 600Â bp; step size: 200Â bp). The X-axis indicates the position of the midpoint of the window; the Y-axis indicates the nucleotide diversity of each windowBack to article page
