There is no generally agreed-to definition of a mitochondrial plasmid, and the different definitions used by various investigators have created some confusion in the literature. We propose that small DNA species present in mitochondria be classified as either defective mitochondrial DNAs (mtDNAs) or mitochondrial plasmids, depending on their origin. We define defective mtDNAs as those small DNA species that derived from the standard mtDNA by deletion and/or rearrangement of mtDNA sequences. Such mtDNAs are defective in the sense that they contain some, but not all, the information required for formation of functional mitochondria.
