摘要

摘要:长imanus Placidochromis longimanus (P. longimanus)是慈鲷科的一种，生活在东非马拉维湖。本研究首次报道了龙尾虾线粒体全基因组，全长16 581 bp，包括13个蛋白质编码基因、2个核糖体RNA、22个转移RNA基因和1个控制区。GC含量为45.99% (A含量为27.44%，T含量为26.58%，C含量为30.11%，G含量为15.87%)，与Astatotilapia calliptera的GC含量(45.90%)相近。我们进一步对上述两个物种和其他11个近缘物种的全线粒体基因组进行了系统发育树，以显示它们的系统发育关系。上述结果将有助于我们对慈鱼科线粒体基因组进化的认识。

The complete mitochondrial genome of the Placidochromis longimanus

Abstract The Placidochromis longimanus (P. longimanus), one species of Cichlidae, resides in the Lake Malawi in East Africa. In present study, for the first time, we reported the complete mitochondrial genome of P. longimanus, which has 16 581 bp in length, including 13 protein-coding genes, 2 ribosomal RNA, 22 transfer RNA genes, and 1 control zone. Moreover, its GC content is 45.99% (27.44% A, 26.58% T, 30.11% C, and 15.87% G), similar to that of Astatotilapia calliptera (the GC content of 45.90%). We further made the phylogenetic tree on the complete mitochondrial genomes of the above two species and other 11 closely related species to show their phylogenic relationship. The above results would facilitate our understanding of the evolution of Cichlidae mitochondrial genome.

期刊介绍： Mitochondrial DNA Part A publishes original high-quality manuscripts on physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism, and/or interactions. Manuscripts on cytosolic and extracellular mtDNA, and on dysfunction caused by alterations in mtDNA integrity as well as methodological papers detailing novel approaches for mtDNA manipulation in vitro and in vivo are welcome. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The Journal also considers manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences, as well as papers that discuss the utility of mitochondrial DNA information in medical studies and in human evolutionary biology.
