Conclusion

- The complete mitochondrial genome of a basal teleost, the Asian arowana (Scleropages formosus, Osteoglossidae)

Although the length, gene content and gene order of the mitochondrial genome of Asian arowana is similar to those of other teleost and vertebrate mitochondrial genomes, it exhibits a number of interesting characteristics. Among them the most interesting is the presence of two different kinds of polymorphic repeat sequences at the opposite ends of the mitochondrial control region. These repeats could be potentially useful for the analysis of genetic diversity of populations, as well as phylogenetic and phylogeographic studies of the Asian arowana and possibly other members of Osteoglossoidae family. The complete mitogenome of Asian arowana provides an additional important dataset for the study of osteoglossids and other basal fish species.
