Mitochondrial DNA. 2013 Jun;24(3):186-8. doi: 10.3109/19401736.2012.744978. Epub 2013 Jan 24.
The total length of the Bufo tibetanus mitochondrial genome sequence is 17,405 bp. It consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 displacement loop (D-loop). Except for eight tRNAs and nd6 genes, all other mitochondrial genes are encoded on the heavy strand (H strand). Most of the 22 tRNA genes can fold into a typical cloverleaf secondary structure by tRNAscan-SE, except for tRNA(Ser). Molecular data presented here provide a useful toll for helping set the stage for further studies and the molecular evolution of the mitochondrial genome.
西藏蟾蜍线粒体基因组序列全长17405碱基对。它由13个蛋白质编码基因、2个核糖体RNA基因、22个转运RNA基因和1个位移环(D环)组成。除了8个转运RNA基因和nd6基因外,所有其他线粒体基因都在重链(H链)上编码。通过tRNAscan-SE分析,22个转运RNA基因中的大多数都能折叠成典型的三叶草二级结构,但tRNA(Ser)除外。本文提供的分子数据为进一步研究和线粒体基因组的分子进化奠定了基础,是一个有用的工具。
