We present the first mitochondrial genome of from the Chagos Archipelago in the British Indian Ocean Territory (BIOT) Marine Protected Area. The mitogenome was 16,702 bp in length and consisted of 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and a non-coding control region (D-loop). GC content was at 38.9%. The control region was 1064 bp in length. This mitogenome for the BIOT MPA differed from the previously published genome by 15 bp and the differences include a 2 bp insertion and 13 single nucleotide polymorphisms distributed across the mitogenome in the BIOT MPA sequence. Whole mitogenome sequence of from the Chagos archipelago presented here fills existing gaps in genetic information on marine species from the BIOT MPA and provides additional tools for species specific assessments as to the effectiveness of MPA management. In addition, methods presented here lay the framework for genetic studies in remote locations with limited infrastructure.
我们展示了来自英属印度洋领地（BIOT）海洋保护区查戈斯群岛的首个线粒体基因组。该线粒体基因组长度为16,702 bp，由13个蛋白质编码基因（PCG）、22个tRNA基因、2个rRNA基因和一个非编码控制区（D环）组成。GC含量为38.9%。控制区长1064 bp。BIOT海洋保护区的这个线粒体基因组与先前发表的基因组有15 bp的差异，这些差异包括在BIOT海洋保护区序列中，线粒体基因组上有一个2 bp的插入和13个单核苷酸多态性。这里展示的来自查戈斯群岛的线粒体全基因组序列填补了BIOT海洋保护区海洋物种遗传信息方面的现有空白，并为海洋保护区管理有效性的物种特异性评估提供了额外工具。此外，这里介绍的方法为基础设施有限的偏远地区的遗传研究奠定了框架。
