Mitochondrial DNA A DNA Mapp Seq Anal. 2016;27(1):212-3. doi: 10.3109/19401736.2014.880893. Epub 2014 Feb 18.
As reported, previous studies of Phoxinus phoxinus ujmonensis (Cypriniformes: Cyprinidae) have focused primarily on morphology and ecology. In this study, we cloned and sequenced the complete nucleotide sequence of the mitochondrial genome for P. phoxinus ujmonensis. The mitogenome was 17,738 bp in length, including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 1 control region. All genes were encoded on the heavy strain except for ND6 and eight tRNA genes. The overall base composition of the heavy strain was 28.50% for A, 28.24% for T, 25.32% for C and 17.94% for G. The control region was revealed to contain tandem repeats. The mitogenome data of P. phoxinus ujmonensis should contribute to phylogenetic analysis and studies of population genetics of Phoxinus fishes.
据报道，此前对乌蒙雅罗鱼（鲤形目：鲤科）的研究主要集中在形态学和生态学方面。在本研究中，我们克隆并测序了乌蒙雅罗鱼线粒体基因组的完整核苷酸序列。该线粒体基因组长度为17738 bp，包括13个蛋白质编码基因、22个转运RNA基因、2个核糖体RNA基因和1个控制区。除了ND6和8个tRNA基因外，所有基因均由重链编码。重链的总体碱基组成为：A占28.50%，T占28.24%，C占25.32%，G占17.94%。研究发现控制区含有串联重复序列。乌蒙雅罗鱼的线粒体基因组数据应有助于雅罗鱼属鱼类的系统发育分析和群体遗传学研究。
