Mitogenome structure from seven sorghum accessions generated using Bandage. a type I genomes with 9 contigs from accession IS929, IS8525, S369 and R931945-2–2, among which R931945-2–2 possessed two contigs with differences in linkage. The nine contigs of IS929 were mapped to all the type I genomes, and the coloring indicates their correspondence in each genome. b type II genomes with six contigs from IS19953 and PI525695. The coloring of the contigs indicates the correspondence of the six contigs of IS19953 with those in PI525695. c type III genome with six contigs, from PI536008. d PCR amplification to verify all 12 linkages of the type I conformation in IS929. The numbers above each lane of the gel refer to linkages spanned by the primers in respect to the contig
