Gene map of the <i>Glycine soja</i> plastid genome.

<p>Thick lines in the red area indicate the extent of the inverted repeat regions (IRa and IRb; 25,574 bp), which separate the genome into small (SSC; 17,896 bp) and large (LSC; 83,181 bp) single-copy regions. Genes located inside the circle are transcribed clockwise, and those outside the circle are transcribed counterclockwise. Genes belonging to different functional groups are colour-coded. The dark grey in the inner circle corresponds to the GC content, and the light grey corresponds to the AT content. The green colour arc indicates the location of the 51-kb inversion.
