Mitochondrial genome of the sucking disc gudgeon, Discogobio yunnanensis (Teleostei, Cypriniformes)

Abstract

The complete mitochondrial genome of Discogobio yunnanensis was determined using the polymerase chain reaction and directly sequenced with the primer walking method. The whole mitogenome was 16,602 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes and 1 control region. It had the typical circular molecule structure of vertebrate’s mitogenome. The whole base composition was estimated to be 32.10% A, 26.79% T, 25.95% C, 15.16% G with AT bias of 58.89%. The complete mitogenome of D. yunnanensis provides the fundamental data for conservation genetics study on this freshwater fish species.
