Figure 1

Organellar map of the chloroplast genomes of U. guianensis (a) and U. tomentosa (b). LSC, large single copy; SSC, small single copy; IRA and IRB, inverted repeat. The colors indicate genes from different functional groups, as shown in the subtitles. The genes inside the circle are transcribed clockwise, and the genes outside the circle counterclockwise, as indicated by the gray arrows. The inner dark gray circle represents the GC content and the light gray circle the AT content. *Genes that contain introns.
