Geminiviruses are plant-infecting, circular single-stranded DNA viruses that have a geminate virion morphology. These viruses infect both cultivated and non-cultivated monocotyledonous and dicotyledonous plants and have a wide geographical distribution. Nine genera had been established within the family Geminiviridae (Becurtovirus, Begomovirus, Capulavirus, Curtovirus, Eragrovirus, Grablovirus, Mastrevirus, Topocuvirus, and Turncurtovirus) as of 2020. In the last decade, metagenomics approaches have facilitated the discovery and identification of many novel viruses, among them numerous highly divergent geminiviruses. Here, we report the establishment of five new genera in the family Geminiviridae (Citlodavirus, Maldovirus, Mulcrilevirus, Opunvirus, and Topilevirus) to formally classify twelve new, divergent geminiviruses.
双生病毒是一类具有孪生病毒粒子形态的植物单链环状 DNA 病毒，能够侵染栽培和非栽培的单子叶和双子叶植物，具有广泛的地理分布。截至 2020 年，双生病毒科已确定了 9 个属（ Becurtovirus、 Begomovirus、Capulavirus、Curtovirus、Eragrovirus、Grablovirus、Mastrevirus、Topocuvirus 和 Turncurtovirus）。在过去的十年中，宏基因组学方法促进了许多新病毒的发现和鉴定，其中包括许多高度分化的双生病毒。在这里，我们报告了双生病毒科的五个新属（Citlodavirus、Maldovirus、Mulcrilevirus、Opunvirus 和 Topilevirus）的确立，以正式分类 12 种新的、分化的双生病毒。
