Figure 1. Gene map of the Hainan C. oleifera chloroplast genome.

The outermost colored blocks represent the physical location of different genes on the chloroplast genome, the inner circle is the physical location of the LSC, SSC, and IR regions on the genome and the different colors represent genes of different functional classes. Genes distributed outside the circle are transcribed counterclockwise, whereas genes inside are transcribed clockwise. The dark gray in the inner circle represents GC content, and the light gray represents AT content.
