Mitochondrial DNA A DNA Mapp Seq Anal. 2017 Jan;28(1):3-4. doi: 10.3109/19401736.2015.1106515. Epub 2015 Dec 7.
Ptychobarbus kaznakovi is endemic to the Qinghai-Tibet Plateau in China. The complete mitochondrial genome of P. kaznakovi was sequenced and characterized. The genome is 16 700 bp in length and contains 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and a non-coding control region. The gene arrangement and nucleotide composition of the mitochondrial genome are similar to those of Cyprinidae fish. A 2 bp tandem repeat was identified in the control region. We conclude that the control region is variable in length between and within species. The complete mitochondrial DNA in this study should be used in the studies on population genetics and phylogeny of P. kaznakovi.
高原裸鲤是中国青藏高原特有的鱼类。对高原裸鲤的线粒体全基因组进行了测序和特征分析。该基因组长度为16700 bp，包含13个蛋白质编码基因、2个核糖体RNA、22个转运RNA和一个非编码控制区。线粒体基因组的基因排列和核苷酸组成与鲤科鱼类相似。在控制区鉴定出一个2 bp的串联重复序列。我们得出结论：控制区在种间和种内长度存在变异。本研究中的线粒体全基因组可用于高原裸鲤的群体遗传学和系统发育研究。
