In this article, we present the nearly complete mitochondrial genome of the Subalpine Kashmir vole (Arvicolinae, Cricetidae, Rodentia), assembled using data from Illumina next-generation sequencing (NGS) of the DNA from a century-old museum specimen. De novo assembly consisted of 16,341 bp and included all mitogenome protein-coding genes as well as 12S and 16S RNAs, tRNAs and D-loop. Using the alignment of protein-coding genes of 14 previously published Arvicolini tribe mitogenomes, seven Clethrionomyini mitogenomes, and also and outgroups, we conducted phylogenetic reconstructions based on a dataset of 13 protein-coding genes (PCGs) under maximum likelihood and Bayesian inference. Phylogenetic analyses robustly supported the phylogenetic position of this species within the tribe Arvicolini. Among the Arvicolini, represents one of the early-diverged lineages. This result of phylogenetic analysis altered the conventional view on phylogenetic relatedness between and and prompted the revision of morphological characters underlying the former assumption. Morphological analysis performed here confirmed molecular data and provided additional evidence for taxonomic replacement of the genus from the tribe Clethrionomyini to the tribe Arvicolini.
在本文中,我们展示了亚高山克什米尔田鼠(仓鼠科田鼠亚科,啮齿目)几乎完整的线粒体基因组,该基因组是利用来自一个百年历史博物馆标本的DNA进行Illumina下一代测序(NGS)数据组装而成的。从头组装得到的线粒体基因组由16,341个碱基对组成,包含所有线粒体基因组蛋白质编码基因以及12S和16S核糖体RNA、转运RNA和控制区。利用先前发表的14个田鼠族线粒体基因组、7个棕背田鼠属线粒体基因组以及外群的蛋白质编码基因序列进行比对,并基于13个蛋白质编码基因(PCG)的数据集,通过最大似然法和贝叶斯推断进行系统发育重建。系统发育分析有力地支持了该物种在田鼠族中的系统发育位置。在田鼠族中,它代表了早期分化的谱系之一。系统发育分析结果改变了关于它与其他物种系统发育关系的传统观点,并促使对先前假设所依据的形态特征进行修订。此处进行的形态学分析证实了分子数据,并为将该属从棕背田鼠属分类到田鼠族提供了额外证据。
