The complete mitochondrial genome sequence of the Poecilia formosa is first reported in this study. The length of genome is 16 550 bp, including 13 protein-coding genes, 2 ribosomal RNA genes and 22 transfer RNA genes. Congeneric mitogenome sequence identity is 87.7% with P. reticulate and 93.1% with P. sphenops. The reconstructed phylogenetic relationships of 16 Cyprinodontiformes species based on 13 protein-coding genes were highly supported and the clade of all Poecilia fishes included had a support value of 100%. Our results shall provide a better understanding in the evolutionary histories of the Cyprinodontiformes.
本研究首次报道了美丽食蚊鱼的完整线粒体基因组序列。基因组长度为16550bp，包括13个蛋白质编码基因、2个核糖体RNA基因和22个转运RNA基因。与网纹食蚊鱼的同属线粒体基因组序列一致性为87.7%，与楔斑食蚊鱼的一致性为93.1%。基于13个蛋白质编码基因重建的16种鲤齿目物种的系统发育关系得到了高度支持，所有食蚊鱼属鱼类的分支支持值为100%。我们的结果将有助于更好地理解鲤齿目的进化历史。
