摘要

Barathrites iris Zugmayer， 1911是一种深海鱼类，生活深度超过3000米。我们成功测序并鉴定了鸢尾花线粒体全基因组，这是一个封闭的圆形分子，长16646 bp， GC含量为48.98%。基于线粒体全基因组序列的蛇形目系统发育分析表明，虹膜小叶蝉与小眼小叶蝉是姐妹类群，同时也支持了蛇形目的多聚性和副兽性。该研究为研究蛇形目动物的深海适应机制提供了宝贵的基因组资源，并有助于我们了解深海硬骨鱼的进化模式。

Complete mitochondrial genome of an abyssal cusk-eel Barathrites iris (Ophidiiformes: Ophidiidae).

Barathrites iris Zugmayer, 1911 is an abyssal fish species inhabiting depths exceeding 3,000 m. We successfully sequenced and characterized the complete mitochondrial genome of B. iris, which represents a closed circular molecule of 16,646 bp with a GC content of 48.98%. Phylogenetic analysis of Ophidiiformes based on whole mitochondrial genome sequences demonstrated that B. iris forms a sister group with Penopus microphthalmus while supporting the polyphyly of Bythitidae as well as the paraphyletic status of Ophidioidei. As the first report of a complete mitochondrial genome for B. iris, this study provides valuable genomic resources for investigating deep-sea adaptation mechanisms in Ophidiiformes and contributes to our understanding of evolutionary patterns in abyssal teleost fishes.
