Complete mitochondrial genome of Sebastes hubbsi (Scorpaenidae, Scorpaeniformes) from the East Sea, Korea

Abstract

Hybrids of Sebastes hubbsi, considered a valid species, have been found in the ocean. To examine the basic characteristics of mitochondrial DNA, we analysed the complete mitogenome of S. hubbsis using next-generation sequencing. The complete mitogenome was 16,453 bp in length and comprised 13 protein-coding genes (PCGs), 2 rRNAs, 22 tRNAs and 1 control region. The complete mitochondrial DNA had 27.9% A, 26.7% T, 17.2% G and 28.3% C, showing a slight AT bias (54.5%). The start codon of all PCGs was ATG, except COX1 (GTG). The stop codons in the PCGs were mainly TAA, except ND1 and ND3 (TAG), ND4 (AGA) and Cytb (incomplete termination codon, T). The tRNAs had a typical cloverleaf structure, except tRNA^{Ser (AGY)} which lacked the DHU arm. The complete mitogenome of S. hubbsi can be used for hybridization or on-going speciation studies within allied species in the Scorpaenidae.
