Abstract

Here we present the first complete mitochondrial genome assembly of Rhynchocypris czekanowskii Dybowski, 1869. We characterized a 16,651-bp circular genome comprising 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a 981-bp control region. Phylogenetic reconstruction using mitochondrial sequences robustly resolved R. czekanowskii as sister to R. lagowskii (bootstrap = 100%), supporting morphological affinities. This work fills a critical genomic gap in Rhynchocypris phylogenetics and has significant implications for both taxonomic revision and the conservation of cold-adapted ichthyofauna in Northeast Asia.

切卡诺斯鲤线粒体全基因组（鲤形，鲤科）。

在这里，我们提出了第一个完整的线粒体基因组组装的Rhynchocypris czekanowskii Dybowski， 1869。我们鉴定了一个16,651 bp的环状基因组，包括13个蛋白质编码基因，22个tRNA基因，2个rRNA基因和一个981 bp的控制区。利用线粒体序列进行系统发育重建，确定了R. czekanowskii是R. lagowskii的姐妹（bootstrap = 100%），支持形态亲缘关系。该研究填补了纹尾鱼系统发育的重要基因组空白，对东北亚冷适应鱼系动物的分类修订和保护具有重要意义。
