The Mohave tui chub () is an endangered cyprinid fish endemic to the Mojave Desert region of southeastern California, USA. Here, we describe the complete 16,607 base pair (bp) mitochondrial genome of . The mitogenome has a nucleotide base composition of A (29.08%), T (26.91%), G (17.58%), and C (26.43%), and encodes 13 protein subunits, 22 tRNAs, a 12S rRNA of 956 bp and 16S rRNA of 1691 bp, and a 929 bp D-loop control region, each located in the conserved mtDNA structure typical for cyprinid fishes. All protein-coding genes have initiation codons of ATG or GTG, and only the , , , , , and genes have complete stop codons. Phylogenetic analyses confirmed the relationship of to several genera of cyprinids (e.g. , ) also endemic to western North America. This characterized mitogenome may help inform management practices for by facilitating future studies on how allopatric populations of this imperiled species are evolving across refuge habitats.
莫哈韦鳟（）是一种濒危鲤科鱼类，原产于美国加利福尼亚州东南部的莫哈韦沙漠地区。在此，我们描述了莫哈韦鳟完整的16,607个碱基对（bp）的线粒体基因组。该线粒体基因组的核苷酸碱基组成为A（29.08%）、T（26.91%）、G（17.58%）和C（26.43%），并编码13个蛋白质亚基、22个tRNA、一个956 bp的12S rRNA和一个1691 bp的16S rRNA，以及一个929 bp的D环控制区，它们各自位于鲤科鱼类典型的保守线粒体DNA结构中。所有蛋白质编码基因的起始密码子为ATG或GTG，只有、、、、和基因具有完整的终止密码子。系统发育分析证实了莫哈韦鳟与同样原产于北美西部的几个鲤科属（如、）之间的关系。这种已表征的线粒体基因组可能有助于为莫哈韦鳟的管理实践提供信息，通过促进未来对这种濒危物种的异域种群如何在避难栖息地中进化的研究。
