The nucleotide diversity among 19 Primulina and three Petrocodon plastomes. (A) The sliding window analysis across the alignment of 19 Primulina + three Petrocodon accessions. (B) The sliding window analysis across the alignment of 19 Primulina plastomes. (C) The sliding window analysis across the alignment of three Petrocodon plastomes. The red dashed line indicates the lowest pi value of 95th percentile windows in the specific alignment. Regions whose pi values are higher than the red dashed line were marked as variable regions. Names of the variable regions colored in black indicate that they are universal to three alignments, while those colored in red indicate they were identified only in one or two of the alignment(s). *The flanking regions of trnT-GGU.
