The Complete Mitochondrial Genome of the Hwanghae Rockfish Sebastes koreanus (Scorpaenidae, Scorpaeniformes)

Abstract

The complete mitochondrial genome sequence of Sebastes koreanus was determined by next-generation sequencing. The total genome was 16,499 bp in length, comprising two rRNA genes, 22 tRNA, genes and 13 protein-coding genes (PCGs), as well as the mtDNA control region. The gene arrangement and composition of the mitogenome appeared similar to that of most vertebrates. The majority of the genes were encoded on the H-strand, with the exception of ND6 (a PCG) and eight tRNAs for Gln, Ala, Asn, Cys, Tyr, Ser (UCN), Glu, and Pro, which were encoded on the L-strand. The genome constitutes 27.9% A, 26.6% T, 17.1% G, and 28.4% C, showing a slight AT bias (54.5%). Of the 13 mitochondrial PCGs, 12 have an ATG start codon while COX1 had a GTG start codon the incomplete stop codon, T, was present in the ND3, ND4, and Cytb genes. The anti-G bias was considerably lower at the third codon position of PCGs (8.8%). The complete mitogenome sequence of S. koreanus will contribute to molecular phylogenetic and evolutionary analyses of Sebastinae and to the identification of its genetic populations in the Yellow Sea. the mtDNA control region.
