title: Complete mitochondrial genome of the Sharpnose stingray Himantura gerrardi (Myliobatiformes: Dasyatidae).
abstract: In this study, we presented the complete mitochondrial genome of the Sharpnose stingray Himantura gerrardi for the first time, which was 17,685 bp in length and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a putative control region. The overall nucleotide composition was 30.1% A, 27.5% C, 14.5% G and 28.0% T. A total of 22 bp overlaps and 83 bp short intergenic spaces were found in the mitogenome. Two start codons (ATG and GTG) and two stop codons (TAG and TAA/T) were used in the protein-coding genes. The origin of L-strand replication (OL) sequence formed a hairpin structure between the tRNA-Asn and tRNA-Cys genes. The termination associated sequence (TAS) formed a hairpin structure near the tRNA-Pro in the control region.
