Percent identity plot comparing the chloroplast genomes of Sect. Marmorata, with P. verticillata as the reference. Vertical scale indicates the percentage of identity, ranging from 50 to 100%. Horizontal axis indicates the coordinates within the chloroplast genomes. Arrows indicate the annotated genes and their transcriptional direction. Genome regions are color coded as exon, rRNA/tRNA, and CNS
