Abstract
The cDNA of lungfish Protopterus annectens myelin DM20 was cloned, and the complete amino acid sequence of Protopterusannectens DM20 was deduced. When five possible phylogenetic trees were tested for the DM20 sequences, the maximum likelihood method supported tree 1 [((tetrapods, lungfish), coelacanth), zebrafish, shark] or tree 5 [(tetrapods, lungfish), (coelacanth, zebrafish), shark]. Both tree 1 and tree 5 indicate that lungfish is phylogenetically the closest to tetrapods among the living fishes.Entities:
