摘要

本研究首次确定了濒危双髻鲨的线粒体全基因组。全长16726 bp，具有典型的脊椎动物基因组成和序列。蛋白质编码基因的总碱基组成分别为31.4% A、26.3% C、13.2% G和29.1% T，共有2种起始密码子(ATG和GTG)和3种终止密码子(TAG、AGA和TAA/TA/T)。除tRNA-Ser2外，其余21个trna可折叠成典型的三叶草结构。控制区在所有线粒体分区中A + T含量最高(66.1%)，G含量最低(12.6%)。

Complete mitochondrial genome of the scalloped hammerhead Sphyrna lewini (Carcharhiniformes: Sphyrnidae).

The complete mitochondrial genome of the endangered scalloped hammerhead Sphyrna lewini was firstly determined in this study. It is 16,726 bp in length with the typical gene composition and orders in vertebrates. The overall base composition is 31.4% A, 26.3% C, 13.2% G and 29.1% T. Two start codon (ATG and GTG) and three stop codon (TAG, AGA and TAA/TA/T) patterns were found in protein-coding genes. Except for the tRNA-Ser2, the remaining 21 tRNAs can be folded into the typical cloverleaf structure. The control region possess the highest A + T content (66.1%) and lowest G content (12.6%) among all mitochondrial partitions.

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.
