Mitochondrial DNA A DNA Mapp Seq Anal. 2017 May;28(3):340-341. doi: 10.3109/19401736.2015.1122772. Epub 2015 Dec 29.
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.
长鳍普提鱼（Placidochromis longimanus，P. longimanus）是丽鱼科的一种鱼类，栖息于东非的马拉维湖。在本研究中，我们首次报道了长鳍普提鱼的完整线粒体基因组，其长度为16581 bp，包括13个蛋白质编码基因、2个核糖体RNA、22个转运RNA基因和1个控制区。此外，其GC含量为45.99%（A为27.44%，T为26.58%，C为30.11%，G为15.87%），与美丽阿非丽鱼（Astatotilapia calliptera，GC含量为45.90%）相似。我们进一步基于上述两个物种以及其他11个近缘物种的完整线粒体基因组构建了系统发育树，以显示它们的系统发育关系。上述结果将有助于我们理解丽鱼科线粒体基因组的进化。
