The complete mitochondrial genome of Rhinogobius maculagenys (Gobiidae:Gobionellinae).

ABSTRACT

The complete mitochondrial genome of Rhinogobius maculagenys Wu et al., (Perciformes,Gobiidae) was sequenced and annotated in this study. The circular mitogenome is 16,500 bp long and consists of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and two main non-coding regions (a putative control region and an L-strand replication origin). The overall base composition is 27.5% A, 25.5% T, 16.9% G, and 30.1% C. The gene order and composition are similar to those of other Gobionellinae species. Phylogenetic analysis revealed that R. maculagenys is closely related to Rhinogobius shennongensis in both the maximum likelihood tree and the Bayesian inference tree. The complete mitogenome of R. maculagenys will serve as a valuable resource for future studies on evolution, taxonomy, and genetic conservation of Rhinogobius.
