Fig 1. Genome map of the Vachellia nilotica and Senegalia senegal chloroplast genome.

Thick lines indicate the extent of the inverted repeat regions (IRa and IRb), which separate the genome into small (SSC) and large (LSC) single copy regions. Genes drawn inside the circle are transcribed clockwise, and those outside are transcribed counterclockwise. Genes belonging to different functional groups are color-coded. The dark grey in the inner circle corresponds to the GC content, and the light grey corresponds to the AT content.
