Dasyatis bennettii is a bottom-dweller that inhabits in the coastal waters of the Indian and Pacific Oceans as well as the freshwaters of Southern China. In this study, we determined the complete mitochondrial genome of this species of stingrays. The results showed that the total length of the mitogenome was 17,668 bp as a circular DNA and contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 control region. The base composition of the complete mitochondrial DNA was 31.1% A, 28.7% T, 26.7% C, and 13.5% G. All the genes in D. bennettii were distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes which were encoded on the L-strand.
本氏黄貂鱼是一种底栖生物,栖息于印度洋和太平洋的沿海水域以及中国南方的淡水区域。在本研究中,我们测定了这种黄貂鱼的完整线粒体基因组。结果显示,该线粒体基因组作为环状DNA全长17,668 bp,包含13个蛋白质编码基因、22个转运RNA基因、2个核糖体RNA基因和1个控制区。完整线粒体DNA的碱基组成为:A占31.1%、T占28.7%、C占26.7%、G占13.5%。本氏黄貂鱼的所有基因都分布在重链上,除了ND6亚基基因和8个在轻链上编码的转运RNA基因。
