Genomic data can improve our understanding on the phylogenetic relationship among Tibetan highland fishes. The whole mitochondrial genome of Gymnocypris eckloni generated in this study is 16,784 bp in length, containing 22 transfer RNA genes, 13 protein-coding genes, two ribosomal RNA genes, and one non-coding control region (D-Loop). Phylogenetic analysis recovers a non-monophyetic population of G. eckloni in the Qaidam basin, representing two distinct lineages designated 'Qiadam A' and 'Qaidam B', within Qaidam A clustering with Chuanchia labiosa and Schizopygopisis pylzovi captured in the Yellow River and Qaidam B grouping with G. eckloni from the Yellow River. Our research may helpful to further reconsideration of clearer taxonomy and improvement of biodiversity conservation strategy of Tibetan highland fishes.
基因组数据可以增进我们对青藏高原鱼类系统发育关系的理解。本研究中获得的黄河高原鳅的线粒体基因组全长为 16784bp，包含 22 个转移 RNA 基因、13 个蛋白质编码基因、两个核糖体 RNA 基因和一个非编码控制区（D 环）。系统发育分析恢复了柴达木盆地黄河高原鳅的非单系种群，代表了两个不同的谱系，分别命名为“柴达木 A”和“柴达木 B”，其中柴达木 A 聚类与黄河中的川陕裂腹鱼和青石爬鮡聚在一起，而柴达木 B 与黄河中的黄河高原鳅聚在一起。我们的研究可能有助于进一步重新考虑青藏高原鱼类更清晰的分类学，并改进生物多样性保护策略。
