Overall distribution of variations (SNPs and indels) across the chloroplast genome. Variations of all 383 accessions and different groups were identified based on the chloroplast reference genome of Oryza rufipogon. Circular map showing the chloroplast genome structure. The unit of the outer distance is kb. “Genes” indicating the genes (including genes, tRNA and rRNA) with their locations on the reference (O. rufipogon) genome. Each colored line indicating one variation. ASW: Asian wild rice, ASC: Asian cultivated rice, AFW: African wild rice, AFC: African cultivated rice. The numbers in the brackets of middle table indicated the number of accessions
