Linear mitochondrial retroplasmid RefSeq Genome. Fusarium oxysporum f. sp. matthiolae

The pFOXC retroplasmids are small, autonomously replicating DNA molecules in the mitochondria of certain Fusarium oxysporum strains and are among the first linear genetic elements shown to replicate via reverse transcription. There is evidence that reverse transcription is protein primed which suggests that the pFOXC retroplasmids may have an evolutionary relationship with hepadnaviruses, the only other retroelement family known to initiate reverse transcription via a protein primer.
