Abstract

Background: Although advances in metagenomics, viral diversity and non-retroviral endogenous viral elements (EVEs) in wheat aphids remain underexplored. By analyzing 470 publicly available datasets and one laboratory-generated transcriptome, the RNA virome and EVEs in the genomes of Sitobion avenae, Schizaphis graminum, and Rhopalosiphum padi were systematically investigated.

Results: We identified 43 RNA viruses, including 12 novel and 31 known RNA viruses. These viruses were widely distributed and abundant in different geographic populations of three wheat aphid species. +ssRNA viruses were the dominant type of aphid viruses. Besides, 90 EVEs were discovered in the genomes of three aphid species. In addition, the EVEs exhibit potential domestication and novel functional roles within aphid genomes.

Conclusions: This study expands the understanding of RNA virus diversity in aphids and provides valuable insights into the potential functions of EVEs in virus-host coevolution.

3种小麦蚜虫RNA病毒的多样性和进化分析。

背景：尽管宏基因组学研究取得了进展，但小麦蚜虫的病毒多样性和非逆转录病毒内源性病毒因子（EVEs）仍未得到充分研究。通过分析470个公开数据集和一个实验室生成的转录组，系统地研究了Sitobion avenae、Schizaphis graminum和Rhopalosiphum padi基因组中的RNA病毒组和evs。结果：共鉴定出43种RNA病毒，其中12种为新型RNA病毒，31种为已知RNA病毒。这些病毒在3种小麦蚜虫不同地理种群中分布广泛、数量丰富。+ssRNA病毒是蚜虫病毒的优势类型。此外，在3种蚜虫的基因组中发现了90个ev。此外，EVEs在蚜虫基因组中表现出潜在的驯化和新的功能作用。结论：本研究扩大了对蚜虫中RNA病毒多样性的认识，并为EVEs在病毒-宿主共同进化中的潜在功能提供了有价值的见解。
