Type 4 of the chloroplast genome of <i>Corydalis</i> species.

Genes shown outside the circle are transcribed in the counter counter-clockwise direction, and those inside the circle are transcribed in the clockwise direction. The colored bars indicate genes belonging to different functional groups. The inner circles denote the GC content (dark grey) and AT content (light grey) of the genome. The ψ signifies pseudogenes.
