Phylogenetic informativeness (Pi), insertions/deletions (indels) and polymorphic sites (SNPs) among the plastomes of Fagopyrum. a Sequence diversity of gene regions. b Sequence diversity of intergenic regions. The X-axis shows the regions in plastomes, while the Y-axis represents the Pi, indels and SNPs at each region. The LSC, IR, and SSC on the X-axis indicate large single-copy, inverted repeat, and small single-copy regions, respectively. The gray shaded regions represent the inverted repeat (IR) regions
