Fig. 1: Annotated gene map of Dendrobium nobile chloroplast genome. Genes shown inside the circle are transcribed clockwise, and genes shown outside the circle are transcribed counterclockwise. Genes belonging to different functional groups are colour-coded. A pair of inverted repeats (IRA and IRB) separates the genome into large single-copy (LSC) and small single-copy (SSC) regions in the inner circle; ψ indicates an ndh pseudogene.
