Abstract

In this study, we employed high-throughput metagenomic data to assemble the mitochondrial genome (mitogenome) of the European greenfinch (Chloris chloris; Linnaeus 1758). The circular mitogenome was 16,813 base pairs (bp) in length, containing 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and 1 control region. The base composition of the mitogenome is 30.6% A, 30.7% C, 14.2% G, and 24.5% T, resulting in a GC content of 44.9%. Phylogenetic analysis, utilizing the concatenation of the 13 mitochondrial PCGs from 32 related species of the order Passeriformes, indicated a closer relationship between C. chloris and C. sinica. Moreover, the genus Chloris was closely related to the genera of Serinus, Crithagra, Carduelis, and Acanthis. This mitogenomic data of C. chloris not only be helpful for species identification but also facilitates our understanding of the evolutionary relationship among different species in genus Chloris, which experienced rapid radiation evolution.

Chloris chloris (Passeriformes: Fringillidae) 的完整线粒体基因组和系统发育分析。

在这项研究中，我们利用高通量元基因组数据组装了欧洲绿雀（Chloris chloris; Linnaeus 1758）的线粒体基因组（有丝分裂基因组）。环形线粒体基因组长度为16,813个碱基对（bp），包含13个蛋白质编码基因（PCGs）、22个tRNA基因、2个rRNA基因和1个控制区。有丝分裂基因组的碱基组成为 30.6% A、30.7% C、14.2% G 和 24.5% T，GC 含量为 44.9%。利用来自 32 个相关百灵鸟目物种的 13 个线粒体 PCGs 连接进行的系统进化分析表明，C. chloris 与 C. sinica 之间的关系更为密切。此外，Chloris 属与 Serinus 属、Crithagra 属、Carduelis 属和 Acanthis 属关系密切。这些有丝分裂基因组数据不仅有助于氯鱼属的物种鉴定，而且有助于我们了解经历了快速辐射进化的氯鱼属不同物种之间的进化关系。
