Abstract

The Clarias fuscus is an important economic fish in China and distributed widely in south China, e.g. Yangtze river, Pearl River, and Min River, even Hainan island. It is also distributed in Southeast Asia and Africa, so it is a good model for study population genetics and geological changes of these region. In this study, the complete mitochondrial genome sequence of C. fuscus has been obtained with PCR. The gene composition and arrangement of mitochondrial genome sequence of C. fuscus are similar to most of other vertebrates, which contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a non-coding control region with total length of 16,518 bp. Most of genes are encoded on Heavy-Strand (H-strand), except for eight tRNA and ND6 genes. Like most vertebrates, the bias of G and C has universality in different region (genes). The complete mitochondrial genome sequence of C. fuscus would contribute for better understanding of population genetics, conservation, biogeography, evolution of this species.

褐藻的完整线粒体基因组(Teleostei,志留目:Claridae)。
fuscus claras fuscus是中国重要的经济鱼类,广泛分布于长江、珠江、闽江等华南地区,甚至海南岛。它在东南亚和非洲也有分布,因此是研究这些地区种群遗传学和地质变化的良好模型。本研究采用PCR方法获得了fuscus的线粒体全基因组序列。fuscus线粒体基因组序列的基因组成和排列与大多数其他脊椎动物相似,包含13个蛋白质编码基因,22个tRNA基因,2个rRNA基因,以及一个总长度为16,518 bp的非编码控制区。除8个tRNA和ND6基因外,大多数基因编码在重链(h链)上。与大多数脊椎动物一样,G和C的偏倚在不同区域(基因)具有普遍性。该物种线粒体全基因组序列的确定将有助于更好地了解该物种的种群遗传学、保护、生物地理学、进化等方面的研究。

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.
