From: Characterization of the chloroplast genome of Gleditsia species and comparative analysis

Nucleotide diversity of chloroplast genomes in Gleditsia. (a): Pi in CDS; (b): Pi in intergenic regions; (c): chloroplast genome Pi values. Note G. sinensis was used as a reference genome for comparison, window length: 300 bp, step length: 200 bp; X axis: position of the midpoint of each window; Y axis: Pi of each window.
