The mitochondrial genome of Fusarium oxysporum.

Physical and genetic maps have been constructed for mtDNA from strains of the fungus Fusarium oxysporum representing three pathogenically specialized forms. All three mtDNA maps are circular. Their sizes are 45 kb for F. oxysporum f.sp. raphani and 52 kb for both F. oxysporum f.sp. conglutinans and F. oxysporum f.sp. matthioli. The genetic loci for cytochrome b, the mitochondrial 25S ribosomal RNA and cytochrome oxidase subunit II, have been identified and are similarly arranged on the three genomes.
