Abstract

Mitochondrial DNA (mtDNA) from the European seabass, Dicentrarchus labrax, has been cloned and characterized. Its gene organization was deduced by a comparison of the sequenced termini of different subclones obtained from European seabass mtDNA to the completely-sequenced mtDNAs from carp and freshwater loach. The difference in genome size between the European seabass mtDNA (approximately 18 kb) and most of the other characterized fish mtDNAs (approximately 16.5 kb) is accounted for by the displacement-loop (D-loop). Comparisons have been performed between the derived amino-acid sequences of three sequenced genes, cytochrome c oxidase subunit 2 (COII), NADH dehydrogenase subunit 4L (ND4L) and ATP synthase subunit 8 (ATPase8), from D. labrax, and their counterparts in other fishes and Xenopus laevis.
