Complete mitochondrial genome of Semicossyphus reticulatus: genome characterization and phylogenetic analysis

Abstract

The Semicossyphus reticulatus is a marine fish species belongs to the family Labridae. To understand the phylogenetic relationship of S. reticulatus in teleost, we firstly determined the complete mitochondrial genome of S. reticulatus. The entire mitochondrial genome (mtDNA) of S. reticulatus is 16610 bp in length, including 13 protein-coding genes and 2 ribosomal RNA genes, 22 tRNAs and 2 main non-coding regions. The gene arrangement, base composition, and tRNA structures of the mtDNA of S. reticulatus is consistent with those of other teleost. The S. reticulatus mtDNA was used to construct phylogenetic tree, which shows that S. reticulatus is clustered with the fishes of the order Perciformes. We expect that the availability of mtDNA of S. reticulatus will facilitate the further investigations of the taxonomic resolution, biogeography and molecular systematic.
