Complete sequence and rearrangement of the mitochondrial genome of Garra qiaojiensis (Cypriniformes: Cyprinidae)

The complete mitochondrial sequence of Garra qiaojiensis was obtained by PCR. It was 17,096bp in length and comprised 22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNA genes and 3 non-coding regions. Unlike the typical mitochondrial genome organization in vertebrate, the mitochondrial genome of G. qiaojiensis was characterized by the distinctive feature: translocation of the tRNA-Pro gene followed by a 258-bp tandem repeat non-coding region. The dinucleotide microsatellite (TA)n which is rather constant in the control region in Cypriniformes was scattered into the tandem repeat non-coding region in the G. qiaojiensis mitochondrial genome with the number of repeated units reduced.
