The complete mitochondrial genome of Xenophysogobio nudicorpa (Teleostei, Cyprinidae, Gobiobotinae)

Abstract

Xenophysogobio nudicorpa is one member of the genus containing two species only, which is a specialized lineage of gobiobotine fishes. In this study, we provide the first mitochondrial genome of X. nudicorpa. The complete mitochondrial genome of X. nudicorpa is 16,616 bp in length, containing 13 protein-coding genes, two rRNA genes (12 S and 16 S rRNA), 22 tRNA genes and a noncoding control region (D-loop). The gene nucleotide composition of X. nudicorpa is 30.5% A, 26.0% T, 16.8% C and 26.7% G, with a slight AT bias of 56.5%. The complete mitochondrial genome of X. nudicorpa would be useful for further studies on genetic diversity and molecular phylogenetic relationship of the subfamily Gobiobotinae.
