Fig. 1. The complete structural chloroplast genome based on the consensus pan-plastome (average size 156,879 ± 166 bp).

The inner genes of the outer circle are transcribed counterclockwise while the outer genes are transcribed clockwise; genes with introns were marked with (*). The dashed area in the inner circle indicates the GC content and is separated into regions as follows: LSC large single-copy, SSC short single-copy, and IR inverted repeats (a) and (b) at the outer border, while the inner border indicates the trimmed pan-plastome used for further analysis (the IRb region trimmed to the least that the ycf1 gene shared between the SSC and IRb regions was fully annotated). The size reached ~132 kb. Within the inner circle, the average sizes of LSC (black), IR (red; either a or b) and SSC (blue) regions are indicated, while the exact size of the alignment above 132 kb (gray) is indicated for each species/variety
