Abstract

Abstract: The complete mitochondrial genome plays an important role in studies of genome-level characteristics and phylogenetic relationships. Here we determined the complete mitogenome sequence of Tridentiger trigonocephalus (Perciformes, Gobiidae), and discovered its phylogenetic relationship. This circular genome was 16 662 bp in length, and consisted of 37 typical genes, including 13 protein-coding genes, 22 tRNA genes, and two rRNA genes. The gene order of T. trigonocephalus mitochondrial genome was identical to those observed in most other vertebrates. Of 37 genes, 28 were encoded by heavy strand, while the others were encoded by light strand. The phylogenetic tree constructed by 13 concatenated protein-coding genes showed that T. trigonocephalus was closest to T. bifasciatus, and then to T. barbatus among the 20 species within suborder Gobioidei. This work should facilitate the studies on population genetic diversity, and molecular evolution in Gobioidei fishes.
