An annotated list of plant viruses and viroids described in Brazil (1926-2018)

Abstract: A list of plant species, in alphabetical order by their scientific name, and the viruses found naturally infecting them in Brazilian territory, with some comments, was prepared . The production of such a list was based on a yearly catalog of publications on plant viruses collected by the author, from 1926 to 2018. Listed species of viruses were those recognized by the International Committee on Taxonomy of Viruses (ICTV), but also those characterized and still waiting official recognition, were included. Several cases of putative viral diseases were listed for historical reasons expecting to raise interest for their clarification. This list includes 345 plants species belonging to 74 families naturally infected by plant viruses in Brazil. Fabaceae and Asteraceae had most virus-infected species, respectively 49 and 36. Until 2018, a total of 213 plant virus and 6 viroid species belonging to 57 genera and 22 families and 6 orders, officially recognized by ICTV, were found naturally infecting these plants. Begomovirus and Potyvirus genera have most representatives, with 45 and 42 species, respectively. There are 59 characterized plant viruses, up to species level, described in Brazil waiting for the inclusion in the ICTV Master Species List. One hundred and thirteen viruses were identified up to genus level but still uncharacterized, while four putative isometric viruses and eleven presumptive viral diseases (“unidentified”) are included in the list. A reverse catalog, listing viruses and the plant species in which they were found is also included.

摘要：本研究编制了一份按学名字母顺序排列的植物物种清单，以及在巴西境内自然侵染这些植物的病毒，并附有相关注释。该清单的编制基于作者于1926年至2018年间收集的植物病毒相关研究文献年度目录。本清单收录的病毒物种既包括国际病毒分类委员会（International Committee on Taxonomy of Viruses, ICTV）认可的物种，也包括已完成特征描述但尚未获得官方认可的物种。出于历史原因，本清单还收录了若干疑似病毒性病害，以期引发学界对其明确鉴定的关注。本清单涵盖了巴西境内自然感染植物病毒的345种植物，隶属于74个科。其中豆科（Fabaceae）和菊科（Asteraceae）的感染病毒植物物种数量最多，分别为49种和36种。截至2018年，共计有213种植物病毒和6种类病毒（viroid）物种自然侵染上述植物，这些物种隶属于57个属、22个科及6个目，且均已获得国际病毒分类委员会的官方认可。双生病毒属（Begomovirus）和马铃薯Y病毒属（Potyvirus）的代表物种数量最多，分别为45种和42种。另有59种在巴西境内完成物种级特征描述的植物病毒，尚未被收录入国际病毒分类委员会的官方物种主清单（ICTV Master Species List）。本清单还收录了113种仅鉴定至属级但未完成特征描述的病毒，以及4种疑似等轴病毒和11种推定的病毒性病害（均为"未鉴定"类型）。此外，本数据集还附带一份反向目录，该目录以病毒为索引，标注其侵染的寄主植物物种。
