The complete mitochondrial genome of Lagocephalus sceleratus (Tetraodontiformes; Tetraodontidae) and phylogenetic studies of Tetraodontidae

Abstract

The complete mitochondrial genome sequence of Lagocephalus sceleratus was determined. The complete mitochondrial genome was 16,444 bp in length and contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and two non-coding region (the control region and the origin of light strand replication). The overall base composition was A 27.59%, C 31.43%, G 17.12%, T 23.85%. All protein-coding genes started with an ATG initiation codon, except COI used GTG. With the exception of ND6 and eight tRNA genes, all other genes were encoded on the heavy strand. Additionally, the phylogenetic relationship of 37 Tetraodontidae species based on the complete genome was analyzed, and the result showed that L. sceleratus was clustered with other Lagocephalus species. These results would be useful for the investigation of phylogenetic relationship, taxonomic classification and phylogeography of the Tetraodontidae.
