Mitochondrial DNA. 2012 Apr;23(2):142-4. doi: 10.3109/19401736.2012.660930. Epub 2012 Mar 7.
The complete mitochondrial genome (mitogenome) of Oxuderces dentatus was determined first. The genome was 17,116 bp in length and consisted of 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes, and 2 main non-coding regions [the control region (CR) and the origin of the light strand replication], the gene composition and order of which was similar to most other vertebrates. The overall base composition of the heavy strand was T 27.9%, C 26.8%, A 30.2%, and G 15.1%, with a slight A+T bias of 58.1%. In addition to the discrete and conserved sequence blocks, unusual long tandem repeat unit (three 150-bp tandem repeat units and an incomplete copy of 146 bp) was also detected within CR. This mitogenome sequence data would play an important role in population genetics and phylogenetic analysis of the Gobioidei.
首次测定了齿吻鳗的完整线粒体基因组（线粒体基因组）。该基因组长度为17116 bp，由13个蛋白质编码基因、22个tRNA基因、2个核糖体RNA基因和2个主要非编码区[控制区（CR）和轻链复制起点]组成，其基因组成和顺序与大多数其他脊椎动物相似。重链的总体碱基组成为T 27.9%、C 26.8%、A 30.2%和G 15.1%，A+T略有偏向，为58.1%。除了离散和保守的序列块外，在CR内还检测到异常长的串联重复单元（三个150 bp的串联重复单元和一个146 bp的不完整拷贝）。该线粒体基因组序列数据将在鳅亚目鱼类的群体遗传学和系统发育分析中发挥重要作用。
