Abstract

We present the mitochondrial genome sequence of a gray reef shark, Carcharhinus amblyrhynchos (Bleeker 1856), a coral reef associated species. This is the first mitogenome for this species from the western Indian Ocean. The mitogenome is 16,705 bp in length, has 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a non-coding control region, and demonstrates a gene arrangement congruent with other shark and most vertebrate species. This mitogenome provides a genomic resource for assisting with population, evolutionary and conservation studies for the gray reef shark, which is increasingly under threat from fisheries.

摘要

我们介绍了一种灰色礁鲨，珊瑚礁相关物种Carcharhinus amblyrhynchos（Bleeker 1856）的线粒体基因组序列。这是来自印度洋西部的该物种的第一个有丝分裂基因组。有丝分裂基因组的长度为16705 bp，具有13个蛋白质编码基因，22个tRNA基因，2个rRNA基因和一个非编码控制区，并显示了与其他鲨鱼和大多数脊椎动物物种一致的基因排列。该有丝分裂基因组为协助灰礁鲨的种群，进化和保护研究提供了基因组资源，灰鲨越来越受到渔业的威胁。
