摘要

本研究旨在研究世界各地不同种类葱属植物中汞齐病毒的多样性。利用GenBank提供的19个Sequence Read Archive序列的转录组学数据，以及从巴西大田洋葱组织中产生的RNA-seq数据，组装了来自世界各地不同葱属植物的9个葱属银汞齐病毒1 (AcAV-1)和9个葱属银汞齐病毒2 (AcAV-2)基因组。序列划分工具分析显示，除中国产葱属AcAV-1分离株外，其他品种的RdRp氨基酸序列同源性均在99%以上。这项工作有助于了解感染葱属的汞齐病毒的遗传多样性。关键词:amalgaviruses;葱属植物转录组数据集;葱属植物sp。

Transcriptomic analyses reveal highly conserved plant amalgavirus genomes in different species of Allium.

This work aims to study amalgavirus diversity in different species of allium collected around the world. Transcriptomic data of 19 Sequence Read Archive runs available at GenBank, as well as RNA-seq data generated from onion tissue from fields in Brazil were used to assemble nine allium cepa amalgavirus 1 (AcAV-1) and nine allium cepa amalgavirus 2 (AcAV-2) genomes from different species of allium worldwide. Sequence demarcation tool analyses of RdRp amino acid sequences revealed identities above 99% within each species, except for an isolate of AcAV-1 from Allium escalonicum from China. This work contributes to the understanding of the genetic diversity of amalgaviruses that infect the genus Allium. Keywords: amalgaviruses; Allium transcriptomic datasets; Allium sp.

期刊介绍： Acta virologica is an international journal of predominantly molecular and cellular virology. Acta virologica aims to publish papers reporting original results of fundamental and applied research mainly on human, animal and plant viruses at cellular and molecular level. As a matter of tradition, also rickettsiae are included. Areas of interest are virus structure and morphology, molecular biology of virus-cell interactions, molecular genetics of viruses, pathogenesis of viral diseases, viral immunology, vaccines, antiviral drugs and viral diagnostics.
