The sequences homologous to Brassicaceae mitochondrial genome plotted on Ogura-type specific region IV. A black line indicates the region specific to the Ogura-type mitochondrial genome (15,255 bp in size) located between syntenic regions 7 and 11. The gene orf138 is located at the edge of this region. Black boxes indicate the sequence homologous to radish and/or other Brassicaceae mitochondrial genomes.
