Chloroplast genome maps of Japanese apricot. a The chloroplast genome of wild group; b The chloroplast genome of domesticated group; c The chloroplast genome of bred group. Genes inside the circle are transcribed clockwise; genes outside are transcribed counter-clockwise. The dark grey inner circle corresponds to the AT content, the green to the GC content. Genes belonging to different functional groups are color-coded
