Nucleotide diversity (pi value) and number of variants among protein-coding genes in PJ plastomes. (A) Total pi value calculated as 0.00080 by DnaSP with sliding window method (Window size: 600 bp, Sliding size: 200 bp). Eleven regions exhibiting higher pi value than other regions were estimated as divergence hotspots. (B) Gray and orange vertical bar indicate SNP and InDel respectively. Yellow, orange, dark orange, and gray horizontal bar under the graph indicate LSC, e-IR, o-IR and SSC regions respectively. Among 76 commonly shared genes in 10 PJ accessions, the identical 31 genes showed no variants among 10 PJ accessions were not marked.
