摘要

背景：蝠鲼科（Mobulidae）是蝠鲼目（Myliobatiformes）中的一个单系科，包括以蝠鲼和魔鬼魟为代表的中上层物种。在蝠鲼属中，大西洋侏儒魔鬼魟（Mobula hypostoma）仅见于大西洋热带和亚热带水深 1 至 100 米的沿海地区。在巴西，M. hypostoma 是研究最少的 Mobula 种类之一。它经常被误认，尤其是被误认为 Mobula thurstoni，在渔业清单中通常被列为副渔获物，或与在巴西境内的偶然发现有关：在此，我们描述了Mobula hypostoma线粒体基因组（有丝分裂基因组）的完整核苷酸序列，其长度为18,141 bp，包括13个蛋白质编码基因、2个核糖体RNA基因和22个转运RNA基因。M.hypostoma的线粒体基因组织和线粒体基因组长度与其他Mobula物种相似，系统发育重建表明M.hypostoma与Mobula munkiana亲缘关系密切：巴西的M. hypostoma有丝分裂基因组有望成为基于分子的物种鉴定、进化和系统地理学研究的宝贵资源。

The complete mitochondrial genome of the endangered Atlantic Pygmy Devil Ray, Mobula hypostoma (Bancroft, 1831), from Brazil.

Background: Mobulidae is a monophyletic family within the Myliobatiformes that comprises pelagic species represented by manta and devil rays. Among the genus Mobula, the Atlantic Pygmy Devil Ray - Mobula hypostoma - is reported in coastal regions exclusively in tropical and subtropical Atlantic Ocean from 1 to 100 m deep. In Brazil, M. hypostoma is one of the least studied Mobula species. It is regularly misidentified, especially as Mobula thurstoni, and is commonly listed as bycatch, in fishery inventories, or related to opportunistic sightings in the national territory.

Methods and results: Here, we describe the complete nucleotide sequence of the mitochondrial genome (mitogenome) from Mobula hypostoma, which is 18,141 bp in length and comprises 13 protein-coding, two ribosomal RNA, and 22 transfer RNA genes. The M. hypostoma mitochondrial genes organisation and mitochondrial genome length are similar to other Mobula species, and the phylogenetic reconstruction indicates M. hypostoma as closely related to Mobula munkiana.

Conclusions: The Brazilian mitogenome of M. hypostoma is expected to be a valuable resource for molecular-based species identification, and evolutionary and phylogeography studies.

期刊介绍： Molecular Biology Reports publishes original research papers and review articles that demonstrate novel molecular and cellular findings in both eukaryotes (animals, plants, algae, funghi) and prokaryotes (bacteria and archaea).The journal publishes results of both fundamental and translational research as well as new techniques that advance experimental progress in the field and presents original research papers, short communications and (mini-) reviews.
