Complete sequence and characterization of mitochondrial DNA genome of Channa asiatica (Perciformes: Channidae).

The complete nucleotide sequence of Channa asiatica mitochondrial (mtDNA) genome was determined in this study. The genome sequence (GenBank accession number KJ930190) was 16,550 base pairs in length, and the gene content and organization on the mitochondrial genome were similar to the other Channa fishes. The overall base composition of C. asiatica mitogenome is 29.4% A, 26.3% T, 15.3% G, 29.0% C, with a high A+T content of 55.7%. The mitochondrial sequence could provide useful genetic information for studying the molecular identification, population genetics, phylogenetic analysis and conservation genetics.
