Abstract
The black-banded trevally (Seriolina nigrofasciata) is a species of the family Carangidae and the only known member of genus Seriolina. To understand the phylogenetic relationship of black-banded trevally in teleost, we first determined the complete mitochondrial genome of black-banded trevally. The entire mitochondrial genome of black-banded trevally is 16 531 bp in length, containing 13 protein-coding genes and 2 ribosomal RNA genes (rRNA), 22 transfer RNA genes (tRNAs), and 2 main non-coding regions. The overall base composition is T 25.8%, C 30.0%, A 26.7%, and G 17.5%. The gene arrangement, base composition, and tRNA structures of black-banded trevally are consistent with those of other teleost. Two of the central conserved sequence blocks (CSB-2 and CSB-3) were identified and the core sequence (TACATGTATGTA) of terminal-associated sequences was recognized in the control region. Meanwhile, the conserved motif 5′-GCCGG-3′ was identified in the origin of light-strand replication of black-banded trevally. The complete mitochondrial genome of black-banded trevally was used to construct phylogenetic tree, which shows that black-banded trevally is clustered with the fishes of the genus Seriola. We expect that the availability of the mitochondrial genome of black-banded trevally will facilitate the further investigations of molecular systematic and phylogenetic analysis of the Carangidae.
