The complete mitochondrial genome of a China endemic fish Discogobio tetrabarbatus is a circular molecular of 16,596 bp in size, containing 13 protein-coding genes(PCGs), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA (rRNA) genes and a non-coding control region. Most of the genes are encoded on the heavy strand, expect for ND6 and eight tRNAs. The control region is 936 bp in length and located between the tRNA(Pro) and tRNA(Phe) genes. Of 13 PCGs, 7 genes (ND2, COII, ATPase 6, COIII, ND3, ND4, Cytb) had an incomplete stop codon. The complete mtDNA genome sequence obtained in this study would be useful for studying genetic diversity and phylogenetics in Discogobio tetrabarbatus and related taxa in future.
中国特有鱼类四须盘鮈的完整线粒体基因组是一个大小为16,596 bp的环状分子，包含13个蛋白质编码基因（PCGs）、22个转运RNA（tRNA）基因、2个核糖体RNA（rRNA）基因和一个非编码控制区。大多数基因由重链编码，但ND6和8个tRNA除外。控制区长度为936 bp，位于tRNA(Pro)和tRNA(Phe)基因之间。在13个PCGs中，7个基因（ND2、COII、ATPase 6、COIII、ND3、ND4、Cytb）具有不完全终止密码子。本研究获得的完整线粒体DNA基因组序列将有助于未来研究四须盘鮈及相关类群的遗传多样性和系统发育。
