Toxabramis houdemeri belongs to the genus Toxabramis in the subfamily of Cultrinae (Cyprinidae). We first determine the complete mitochondrial genome of T. houdemeri in this study. It is 16 618 bp in length, with the base composition on the heavy strand: 30.79% A, 16.61% G, 27.29% C, and 25.31% T. It has the typical vertebrate mitochondrial gene arrangement, including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a D-loop region. Phylogenetic analysis showed that T. houdemeri was clustered into one branch of the subfamily of Cultrinae, and closely related to Hemiculter leucisculus. The present study will contribute to genetic resources conservation of T. houdemeri and studying its population genetic structure and phylogenetic relationships.
兴凯似鲴属于鲤科雅罗鱼亚科似鲴属。在本研究中，我们首次测定了兴凯似鲴的完整线粒体基因组。其长度为16618 bp，重链上的碱基组成为：A占30.79%，G占16.61%，C占27.29%，T占25.31%。它具有典型的脊椎动物线粒体基因排列，包括13个蛋白质编码基因、22个tRNA基因、2个rRNA基因和一个D-loop区。系统发育分析表明，兴凯似鲴聚为雅罗鱼亚科的一个分支，与麦穗鱼亲缘关系较近。本研究将有助于兴凯似鲴遗传资源的保护及其种群遗传结构和系统发育关系的研究。
