Mitochondrial DNA A DNA Mapp Seq Anal. 2016;27(1):251-2. doi: 10.3109/19401736.2014.883610. Epub 2014 Feb 13.
The complete mitochondrial DNA genome of Gymnodiptychus pachycheilus was sequenced and characterized. The genome is 16,586 bp in length. As with most teleosts, the mitogenome of G. pachycheilus is structurally conserved, containing two ribosomal RNA (rRNA) genes, 13 protein-coding genes, 22 transfer RNA (tRNA) genes and one displacement loop (D-loop) region. The 12 heavy-strand protein-coding genes of G. pachycheilus and other 15 Schizothoracinae species were used for phylogenetic analysis by Bayesian inference and maximum likelihood methods. The topology demonstrated that G. pachycheilus is relatively close to species in genera of Gymnocypris, Schizopygopsis and Oxygymnocypris but differentiated earlier in Schizothoracinae than them.
对厚唇裸重唇鱼的完整线粒体DNA基因组进行了测序和特征分析。该基因组长度为16586 bp。与大多数硬骨鱼一样,厚唇裸重唇鱼的线粒体基因组在结构上是保守的,包含两个核糖体RNA(rRNA)基因、13个蛋白质编码基因、22个转运RNA(tRNA)基因和一个位移环(D-loop)区域。利用贝叶斯推断和最大似然法,对厚唇裸重唇鱼的12个重链蛋白质编码基因和其他15个裂腹鱼亚科物种进行了系统发育分析。系统发育树表明,厚唇裸重唇鱼与裸鲤属、裂腹鱼属和尖裸鲤属的物种亲缘关系相对较近,但在裂腹鱼亚科中比它们分化得更早。
