Additional file 5 of Evolutionary directions of single nucleotide substitutions and structural mutations in the chloroplast genomes of the family Calycanthaceae

Additional file 5: Figure S1. Chloroplast genome map of Chimonanthus praecox, a representative of all four newly determined chloroplast genomes. The genes inside and outside the circle are transcribed clockwise and counterclockwise, respectively. Genes that belong to different functional groups are represented by different colors. The thick lines indicate the extent of the inverted repeats (IRa and IRb) that separate the genomes into small (SSC) and large (LSC) single-copy regions. The flower in the center is of Chimonanthus praecox.
