Figure 1. Circular gene map of the chloroplast genome ofPrimula wilsonii . The thick lines indicate the inverted repeat regions (IRa and IRb) that separate the genome into small (SSC) and large (LSC) single copy regions. Genes on the inside of the map are transcribed clockwise, while those on the outside are transcribed counterclockwise. Genes grouped by different functions are shown in different colors.
