双生病毒科包括具有双生颗粒形态的感染植物的环状单链DNA病毒。该科的成员感染单子叶植物和双子叶植物，并且几乎分布于全球。随着新分子工具和低成本测序的出现，在各种栽培和非栽培植物中新双生病毒的发现显着增加。在本次通讯中，我们重点介绍了三个新属（Becurtovirus、Eragrovirus 和 Turncurtovirus）的建立，以适应各种最近发现的高度分化的双生病毒，并且在某些情况下具有独特的基因组结构。 Becurtovirus 属有两个病毒种：甜菜卷顶伊朗病毒（28 个分离株；叶蝉载体Circulifer haematoceps）和菠菜卷顶亚利桑那病毒（1 个分离株；未知载体），而画眉草病毒属和 Turncurtovirus 各有一个指定种：Eragrostis curvula streak 病毒（6 个分离株；未知载体）和芜菁卷顶病毒（20 个分离株；叶蝉）分别为Circulifer haematoceps)。基于对公共数据库中三个新属的所有可用基因组序列的分析，我们为这三个新属内的物种和菌株分类提供了指南和方案。
The familyGeminiviridaeincludes plant-infecting circular single-stranded DNA viruses that have geminate particle morphology. Members of this family infect both monocotyledonous and dicotyledonous plants and have a nearly global distribution. With the advent of new molecular tools and low-cost sequencing, there has been a significant increase in the discovery of new geminiviruses in various cultivated and non-cultivated plants. In this communication, we highlight the establishment of three new genera (Becurtovirus, EragrovirusandTurncurtovirus) to accommodate various recently discovered geminiviruses that are highly divergent and, in some cases, have unique genome architectures. The genusBecurtovirushas two viral species,Beet curly top Iran virus(28 isolates; leafhopper vectorCirculifer haematoceps) andSpinach curly top Arizona virus(1 isolate; unknown vector), whereas the generaEragrovirusandTurncurtoviruseach have a single assigned species:Eragrostis curvula streak virus(6 isolates; unknown vector) andTurnip curly top virus(20 isolates; leafhopper vectorCirculifer haematoceps), respectively. Based on analysis of all of the genome sequences available in public databases for each of the three new genera, we provide guidelines and protocols for species and strain classification within these three new genera.
