Abstract
The complete mitogenome of an endemic fish in China flat-lip gudgeon, Platysmacheilus exiguous, was determined using the polymerase chain reaction and directly sequenced with the primer walking method. The whole mitogenome was 16,604 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 30.77%A, 26.06%T, 26.64%C and 16.53%G with AT bias of 56.83%. The complete mitogenome of P. exiguus provides the fundamental data for conservation genetics study on this species.
