Complete sequence of the mitochondrial genome of Uranoscopus tosae: genome characterization and phylogenetic analysis

Abstract

Uranoscopus tosae is a marine fish which some wild populations are in danger, and need urgent conservation. In this study, the complete mitochondrial genome of the U. tosae which is 17,286 base pairs in length, and contained 13 protein-coding genes and 2 ribosomal RNA genes, 22 tRNA genes and 2 main non-coding regions was firstly determined. Most of the genes of U. tosae were encoded on the H-strand, while the ND6 and eight tRNA (Gln, Ala, Asn, Cys, Tyr, Ser (UCN), Glu and Pro) genes were encoded on the L-strand. In addition, the complete mitochondrial genome of U. tosae was used to construct phylogenetic tree, which shows that U. tosae clustered with the species of Howellidae. The mitochondrial genome of U. tosae provides important data for studying on population genetic diversity and genetic conservation.
