In our research, the complete mitochondrial DNA (mtDNA) of was obtained from the dorsal myotome of the fish. The total length of the mitochondrial genome is 16,617 bp and deposited in GenBank with accession number KU198332. The gene arrangement was similar to other bony fishes, which contained 37 genes (13 protein-coding genes, 2 ribosomal RNA and 22 transfer RNAs) and a major non-coding control region. The mtDNA may provide some important genetic background information of this valuable fish. The G contents was relatively low in the total mtDNA with the GCskewthinsp;= -0.22. The negative GC-skew ranging from -0.51(ATP8) to -0.19(CO1), and the more positive AT-skew varying from -0.26(ATP8) to -0.03(CO1). The phylogenetic analysis demonstrated that was clustered together with which could be a sister species.
在我们的研究中,从该鱼类的背侧肌节中获得了完整的线粒体DNA(mtDNA)。线粒体基因组的总长度为16,617 bp,并以登录号KU198332保存在GenBank中。基因排列与其他硬骨鱼类相似,包含37个基因(13个蛋白质编码基因、2个核糖体RNA和22个转运RNA)以及一个主要的非编码控制区。该mtDNA可能为这种珍贵鱼类提供一些重要的遗传背景信息。总mtDNA中的G含量相对较低,GC偏斜度为-0.22。负的GC偏斜度范围从-0.51(ATP8)到-0.19(CO1),而正的AT偏斜度变化更大,从-0.26(ATP8)到-0.03(CO1)。系统发育分析表明,该物种与可能是姐妹物种的另一物种聚集在一起。
