The complete mitochondrial genome of Pareuchiloglanis gongshanensis (Siluriformes, Sisoridae, Pareuchiloglanis): genome characterization and phylogenetic analysis.

Pareuchiloglanis gongshanensis, a small-sized benthic fish, distributed in southwest China. In the present study, the complete mitochondrial genome of P. gongshanensis was sequenced to be 16 588 bp in length, including 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, a control region and the origin of the light strand replication. The overall nucleotide composition was 30.70% A, 24.11% T, 29.16% C and 16.02% G, with an A + T bias of 54.82%. The gene composition and the structural arrangement of the P. gongshanensis complete mitochondrial DNA were identical to most of the other vertebrates. This will provide a useful tool for understanding the genetic diversity, population structure and conservation status of P. gongshanensis in the future.
