Fig. 1

Chloroplast genome map of Polystachya species. The full circles represent common genes annotated for the six Polystachya species in this study, and the red empty box indicates differences in the genes annotated in this region of these plastomes. The bottom of the figure exhibits the differences in the genes annotated in this region for the plastomes. Genes shown outside the circle are transcribed in the counter counterclockwise direction, while those inside the circle are transcribed in the clockwise direction. The colored bars indicate genes belonging to different functional groups. The darker gray inside the inner circle denotes GC content while the lighter gray corresponds to the AT content of the genome. The ψ signifies pseudogenes
