Bats represent around one-fourth of the world's mammals and their taxonomy is still controversial. Molossids are one of the most diverse bat families with a wide knowledge gap. In this study, we report the first complete mitochondrial genomes of three molossid bats: the European free-tailed bat , the La Touche's free-tailed bat , and the Wrinkle-lipped free-tailed bat . The mitogenomes are 16,869 and 16,784 bp long for and , respectively, while in it is at least 16,216 bp although the control region was not fully recovered due to its higher divergence from . The genomes show conserved synteny with other mammalian mitogenomes, containing 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 control region (d-loop). All protein-coding genes start with the ATG start codon, except for ND2, ND3, and ND5 which begin with ATA or ATT. Eleven protein-coding genes terminated in a canonical stop codon, TAA or TAG, two contain incomplete stop codons, T or TA. Cytochrome b terminates in the mitochondria-specific stop codon AGA. These mitogenomes provide a valuable resource for future studies of Molossidae and other bat and mammal species.
蝙蝠约占全球哺乳动物种类的四分之一，其分类学仍存在争议。犬吻蝠科是种类最多样化的蝙蝠家族之一，存在较大的知识空白。在本研究中，我们报告了三种犬吻蝠科蝙蝠的首个完整线粒体基因组：欧洲游离尾蝠、拉氏游离尾蝠和皱唇游离尾蝠。欧洲游离尾蝠和拉氏游离尾蝠的线粒体基因组长度分别为16,869和16,784碱基对，而皱唇游离尾蝠的线粒体基因组长度至少为16,216碱基对，不过由于其与其他两者差异较大，控制区未完全获得。这些基因组与其他哺乳动物的线粒体基因组具有保守的同线性，包含13个蛋白质编码基因、2个核糖体RNA基因、22个转运RNA基因和1个控制区（D环）。除ND2、ND3和ND5以ATA或ATT起始外，所有蛋白质编码基因均以ATG起始密码子开始。11个蛋白质编码基因以典型的终止密码子TAA或TAG结束，2个含有不完整的终止密码子T或TA。细胞色素b在线粒体特异性终止密码子AGA处结束。这些线粒体基因组为未来犬吻蝠科以及其他蝙蝠和哺乳动物物种的研究提供了宝贵资源。
