In this research, the mitochondrial genome of the was sequenced and examined for the first time to enhance the comprehension of the phylogenetic relationships within the Columbidae. The complete mitochondrial genome of (17,160 bp) was structurally similar to the recognized members of the Columbidae family, but with minor differences in gene size and arrangement. The structural AT content was 54.12%. Additionally, 150 mitochondrial datasets, representing valid species, were amassed in this investigation. Maximum likelihood (ML) and Bayesian inference (BI) phylogenetic trees and evolutionary time relationships of species were reconstructed based on cytb gene sequences. The findings from the phylogenetic evaluations suggest that the was classified under the Columbinae subfamily, diverging from the Miocene approximately 8.1 million years ago, indicating intricate evolutionary connections with its close relatives, implying a history of species divergence and geographic isolation. The diversification of the Columbidae commenced during the Late Oligocene and extended into the Miocene. This exploration offers crucial molecular data for the , facilitating the systematic taxonomic examination of the Columbidae and Columbiformes, and establishing a scientific foundation for species preservation and genetic resource management.
在本研究中,首次对[物种名称]的线粒体基因组进行了测序和检测,以增进对 Columbidae 科内系统发育关系的理解。[物种名称]的完整线粒体基因组(17,160 碱基对)在结构上与 Columbidae 科已识别的成员相似,但在基因大小和排列上存在细微差异。结构 AT 含量为 54.12%。此外,在本次调查中收集了 150 个代表有效物种的线粒体数据集。基于 cytb 基因序列重建了最大似然(ML)和贝叶斯推断(BI)系统发育树以及物种的进化时间关系。系统发育评估的结果表明,[物种名称]被归类在 Columbinae 亚科之下,大约在 810 万年前从中新世分化出来,这表明它与其近亲有着复杂的进化联系,意味着物种分化和地理隔离的历史。Columbidae 的多样化始于渐新世晚期并延续到中新世。这一探索为[物种名称]提供了关键的分子数据,有助于对 Columbidae 和 Columbiformes 进行系统的分类学研究,并为物种保护和遗传资源管理奠定科学基础。
