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

Abstract

Sebastes is a diverse genus of fish in the family Scorpaenidae. The larvae and adults in this genus have similar morphological characteristics. To obtain basic information for their identification, the mitogenome of S. steindachneri was sequenced using next-generation sequencing. The mitogenome was 16,450 bp in length, and comprised of 13 protein-coding genes (PCGs), 2 rRNAs, 22 tRNAs, and a control region. The mitogenome is 27.4% A, 21.1% T, 17.5% G, and 28.0% C, showing a slight AT bias (54.5%). ATG was the start codon in all of the PCGs, except COX1 (GTG). The termination codon in the PCGs was TAA, except in ND1 and ND3 (TAG), ND4 (AGA), and Cytb (incomplete termination codon, T). All of the tRNAs had a typical cloverleaf shape, except tRNA^Ser(AGY), which lacked the DHU arm. The mitogenome of S. steindachneri should be useful for identifying larvae and constructing a phylogenetic structure for the Scorpaenidae.
