The complete mitochondrial genome of Yaoshania pachychilus (CHEN, 1980) (Cyprinifromes, Balitoridae)

The complete mitochondrial genome of Yaoshania pachychilus (Protomyzon pachychilus) was determined for the first time. This mitogenome was 16 564 bp in length, including two ribosomal RNA genes, 22 transfer RNA genes, containing 13 protein-coding genes and a control region (D-loop). The base composition of the heavy strand was 28.9% A, 25.2% T, 28.7% C and 17.2% G. As in other vertebrates, with the exception of the eight tRNA genes and NADH dehydrogenase subunit 6 (ND6), all other mitochondrial genes are encoded on the heavy strand. Only the tRNA-Ser was not folded into a typical clover-leaf secondary structure as it lacks the dihydrouridine arm.
