Sliding window test of nucleotide diversity (π) in the Chiloschista Plastomes. (A) The nucleotide diversity of complete plastome, six mutation hotspot regions (π > 0.06) were annotated. (B) The nucleotide diversity of 68 protein coding sequence, five mutation hotspot region (π > 0.03). The window size was set to 100 bp and the sliding windows size was 25 bp. X-axis, position of the midpoint of a window; Y-axis, π values of each window
