BACKGROUND The mitochondrial genome of Metazoa is usually a compact molecule without introns. Exceptions to this rule have been reported only in corals and sea anemones (Cnidaria), in which group I introns have been discovered in the cox1 and nad5 genes. Here we show several lines of evidence demonstrating that introns can also be found in the mitochondria(More)
BACKGROUND Animal mitochondrial introns are rare. In sponges and cnidarians they have been found in the cox 1 gene of some spirophorid and homosclerophorid sponges, as well as in the cox 1 and nad 5 genes of some Hexacorallia. Their sporadic distribution has raised a debate as to whether these mobile elements have been vertically or horizontally transmitted(More)
