Fig. 4.

Schematic representation of gene transfer between the chloroplast and mitochondrial genomes from Panax species. Each gray line within the circle shows the regions of chloroplast genome that has been inserted into the indicated location in the mitochondrial genome. Colored boxes show conserved chloroplast genes, classified based on product function. Genes shown inside the circle are transcribed clockwise, and those outside the circle are transcribed counterclockwise.
