The complete mitochondrial genome sequence of Takifugu flavidus (Tetraodontiformes: Tetrodontidae)

Abstract

The complete mitochondrial genome of Takifugu flavidus (Tetraodontiformes: Tetrodontidae) was obtained in this study. The mitogenome is 16,449 bp in size and contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 2 non-coding regions: origin of light-strand replication (O_L) and control region (D-loop). The overall nucleotide composition of the heavy strand was 29.88% A, 25.81% T, 15.28% G and 29.03% C, with a slight AT bias of 55.69%. Except for ND6 gene and eight tRNA genes, other genes are encoded on the heavy strand. The mitochondrial genome data of T. flavidus should contribute to phylogenetic analysis and studies on genetic structure, as well as molecular phylogeny and species identification of Tetrodontidae.
