Xenophysogobio nudicorpa is a rare and endemic fish species found only in the upper Yangtze River basin in China. Here, the complete mitochondrial genome of X. nudicorpa ha been determined by polymerase chain reaction and directly sequenced with primer walking method. The genome was 16,592 bp in length and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a non-coding control region (D-loop). The gene order and composition of X. nudicorpa was similar to most other vertebrates. The overall base composition of the heavy strand was 30.22% A, 27.09% T, 25.76% C and 16.93% G, with a slight AT bias of 57.31%. The complete mitogenome sequence of X. nudicorpa provides fundamental data for further conversation genetics and captive breeding studies on this species.
裸腹 Xenophysogobio nudicorpa 是一种珍稀的特有鱼类，仅在中国长江上游流域发现。在此，通过聚合酶链反应并采用引物步移法直接测序，确定了裸腹 Xenophysogobio nudicorpa 的完整线粒体基因组。该基因组长度为 16,592 bp，包含 13 个蛋白质编码基因、2 个 rRNA 基因、22 个 tRNA 基因和一个非编码控制区（D 环）。裸腹 Xenophysogobio nudicorpa 的基因顺序和组成与大多数其他脊椎动物相似。重链的总体碱基组成为 30.22% A、27.09% T、25.76% C 和 16.93% G，AT 偏倚率为 57.31%，略有 AT 偏向。裸腹 Xenophysogobio nudicorpa 的完整线粒体基因组序列为该物种进一步的保护遗传学和圈养繁殖研究提供了基础数据。
