Here we present the first complete mitochondrial genome assembly of 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 as sister to (bootstrap = 100%), supporting morphological affinities. This work fills a critical genomic gap in phylogenetics and has significant implications for both taxonomic revision and the conservation of cold-adapted ichthyofauna in Northeast Asia.
在此,我们展示了1869年戴氏(Dybowski)鱼类的首个完整线粒体基因组组装。我们鉴定出一个16,651碱基对的环状基因组,包含13个蛋白质编码基因、22个tRNA基因、2个rRNA基因和一个981碱基对的控制区。使用线粒体序列进行的系统发育重建有力地解析出其为[某物种]的姐妹种(自展值 = 100%),支持了形态学上的亲缘关系。这项工作填补了[某物种]系统发育学中一个关键的基因组空白,对分类学修订以及东北亚冷适应鱼类区系的保护都具有重要意义。
