We report the first complete mitochondrial genome of a shortfin mako shark from the Atlantic Ocean. The genome had 16,700 base pairs and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a non-coding D-loop. There were 81 individual differences compared to the published mitochondrial genome of a shortfin mako from the Pacific Ocean, with most variability found in protein coding genes, especially ND5, ND3, and ND1. These highly variable genes may be useful population markers in future studies, and availability of a second mitogenome will assist with future, genome-scale studies of this IUCN Endangered species.
我们报告了来自大西洋的一条灰鲭鲨的首个完整线粒体基因组。该基因组有16,700个碱基对，包含13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和一个非编码D环。与已发表的来自太平洋的灰鲭鲨线粒体基因组相比，存在81个个体差异，其中大部分变异存在于蛋白质编码基因中，尤其是ND5、ND3和ND1。这些高度可变的基因可能在未来研究中成为有用的种群标记，第二个线粒体基因组的可得性将有助于对这种世界自然保护联盟濒危物种进行未来的全基因组规模研究。
