Abstract

BACKGROUND

Verma, 1967 (Macrosiphini: Aphidinae), is a genus within Aphididae (aphids) with ecological importance and a unique distribution, but there is a lack of mitogenomic data on the evolutionary relationships within this genus, hindering a comprehensive understanding of its evolutionary history.

METHODS

In this study, we present the complete mitochondrial genome sequence and features of (David, Rajasingh & Narayanan, 1972) (Hemiptera: Aphididae) and further infer its phylogenetic position based on the complete mitochondrial genome sequence.

RESULTS

The complete mitochondrial genome of is 17,161 bp in length, including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, a control region, and a repeat region between and . Phylogenetic analyses based on complete mitochondrial genomes of Aphidinae indicated that the two constituent tribes, Macrosiphini and Aphidini, are monophyletic. was robustly clustered with the members of and . Together, these three genera form the most basal clade within Macrosiphini.

CONCLUSIONS

The complete mitogenome of contains multiple conserved features relative to other aphids, including gene order, nucleotide composition, codon bias, and repeat region. The phylogenetic relationships within Macrosiphini reported here are consistent with previous studies. Our results provide new insights into the phylogenetic position of the genus .

摘要

背景

Verma属（蚜科：蚜亚科）于1967年被建立，在蚜虫中具有重要的生态学意义和独特的分布，但缺乏该属内进化关系的线粒体基因组数据，这阻碍了对其进化历史的全面理解。

方法

在本研究中，我们展示了（David、Rajasingh和Narayanan，1972年）（半翅目：蚜科）的完整线粒体基因组序列和特征，并基于完整的线粒体基因组序列进一步推断其系统发育位置。

结果

该物种的完整线粒体基因组长度为17,161 bp，包括13个蛋白质编码基因、22个转运RNA基因、2个核糖体RNA基因、一个控制区以及和之间的一个重复区。基于蚜亚科完整线粒体基因组的系统发育分析表明，其两个组成部落，即长管蚜族和蚜族，是单系的。该物种与和的成员紧密聚类。这三个属共同构成了长管蚜族中最基部的分支。
