Mitochondrial genome rearrangements in ecotypes Col-0, C24 and L er. (A) Genome maps are constructed from sequence data. Regions are color-coded, with genes shown in green and selected repeats shown in red. Underlying bars represent regions that are inverted in orientation relative to the genomic map of Col-0. (B) List of structural variations in Col-0 and Landsberg erecta (Ler) genes relative to C24. The position and type of polymorphism are shown.
