We assembled and annotated the complete mitochondrial genomes of (hoary fox), (bush dog), (white-lipped peccary), and (Brazilian free-tailed bat). The mitogenomes exhibited typical vertebrate structures, containing 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes, and a D-loop region. Phylogenetic reconstruction using the 13 protein-coding genes revealed robust relationships among species within Carnivora, Chiroptera, and Artiodactyla, corroborating previous studies. Secondary structure analysis of tRNAs and ribosomal genes showed slight variations among species of the same order. This research highlights the importance of mitochondrial genomics in understanding the evolutionary relationships and genetic diversity of Cerrado mammals, contributing to conservation efforts for this unique ecosystem.
我们组装并注释了苍狐、薮犬、白唇西貒和巴西无尾蝠的完整线粒体基因组。这些线粒体基因组呈现出典型的脊椎动物结构，包含13个蛋白质编码基因、22个tRNA基因、2个核糖体RNA基因和一个D环区域。使用13个蛋白质编码基因进行的系统发育重建揭示了食肉目、翼手目和偶蹄目物种之间的稳健关系，证实了先前的研究。tRNA和核糖体基因的二级结构分析表明，同一目的物种之间存在细微差异。这项研究突出了线粒体基因组学在理解塞拉多哺乳动物的进化关系和遗传多样性方面的重要性，有助于对这一独特生态系统的保护工作。
