Fig. 1

The plastid genome map (A) and nrDNA structure (B) for the 13 Justicia species. The genes drawn on the outside of the circle are transcribed clockwise, while those inside of the circle are transcribed counter clockwise. Genes belonging to different functional groups are color coded. Small single copy (SSC), large single copy (LSC), and inverted repeats (IRa, IRb) are indicated directly
