Characterization and phylogenetic analysis of the complete mitochondrial genome of Rhinogobius wuyanlingensis (Gobiiformes: Gobiidae: Gobionellinae)

Rhinogobius wuyanlingensis is endemic to the upper reaches of Feiyunjiang river basin. In this article, the complete mitochondrial genome (mtDNA) for this freshwater goby was first determined. Sequence analysis showed the genome consisted of 13 protein-coding genes, 22 tRNA genes, two ribosomal RNA genes, and two main non-coding regions (the control region and the origin of the light strand replication). This circular molecule was 16,491 bp in length with a slight AT bias of 53.5%. In the phylogenetic tree, R. wuyanlingensis was closer to Rhinogobius brunneus, Rhinogobius yonezawai, Rhinogobius flumineus, and Rhinogobius cliffordpopei. The mitochondrial genome of R. wuyanlingensis reported here would provide basal molecular data for evolution, taxonomy, and population genetics of Rhinogobius.
