Figure 1

Complete chloroplast genome circle map of the seven studied Citrullus species. Genes outside the circle are transcribed on the positive chain, whereas those genes inside the circle are transcribed on the negative chain. Boxes with different colors represent genes with a different functional group. The inner ring shows the positions of LSC, IRa, SSC, and IRb, with the GC clamp of the chloroplast genome shown in grey. The chloroplast genome map was draw using OGDRAW v1.3.1 (https://chlorobox.mpimp-golm.mpg.de/OGDraw.html).
