Fig. 5

Median-joining network of eight haplotypes (H1–H8) based on sequence variations in three non-coding regions of E. arundinaceus cpDNA. a Locations of the three regions (rps16–trnQ, atpA–rps14, and rpl16–rps3). The position (bp) of each region in full-length cpDNA of E. arundinaceus accession ‘JW630’ is given in parentheses. LSC, large single-copy region; IR, inverted repeat; SSC, small single-copy region. b Circle sizes are proportional to haplotype frequency, and their colors correspond to those in Fig. 1 at K = 4. Positions of mutational steps in concatenated sequences between haplotypes are shown next to the branches. Positions of mutational steps in each cpDNA region are shown in parentheses. Haplotype of each accession is indicated in Table S2
