Abstract

In this study, we first presented the complete mitochondrial genome of the blue shark Prionace Glauca, a pelagic and oceanic species. It is 16,705 bp in length and contains 2 rRNA genes, 22 tRNA genes, 13 protein-coding genes and 1 putative control region. The overall base composition is 31.6% A, 24.4% C, 13.1% G and 30.9% T. Overlaps and short inter-genic spaces are located in the genome. The tRNA-Ser2 loses the dihydrouridine arm and cannot be folded into the typical clover-leaf secondary structure. Two start codons (GTG and ATG) with two stop codons (TAG and TAA) or with one incomplete stop codon (T) are found in the 13 protein-coding genes. The control region contains high A + T (69.9%) and low G (12.0%).

青鲨(蓝鳃目:鲨目)线粒体全基因组的研究。

在这项研究中，我们首次提出了蓝鲨Prionace Glauca的完整线粒体基因组，这是一种远洋和海洋物种。全长16705 bp，包含2个rRNA基因、22个tRNA基因、13个蛋白编码基因和1个推定控制区。总体碱基组成为31.6% A, 24.4% C, 13.1% G和30.9% t，基因组中存在重叠和短的基因间空间。tRNA-Ser2失去了二氢吡啶臂，不能折叠成典型的三叶草二级结构。在13个蛋白编码基因中发现两个起始密码子(GTG和ATG)带有两个终止密码子(TAG和TAA)或一个不完全终止密码子(T)。控制区为高A + T(69.9%)和低G(12.0%)。

期刊介绍： Previously published under the title DNA Sequence (Vols 1-19.3), Mitochondrial DNA accepts original high-quality reports based on mapping, sequencing and analysis of mitochondrial DNA and RNA. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, medical genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The editorial board will also consider manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences.
