DNA viruses of the Archaea have highly diverse and often exceptionally complex morphotypes. Many have been isolated from geothermally heated hot environments, raising intriguing questions about their origins, and contradicting the widespread notion of limited biodiversity in extreme environments. Here, we provide a unifying view on archaeal viruses, and present them as a particular assemblage that is fundamentally different in morphotype and genome from the DNA viruses of the other two domains of life, the Bacteria and Eukarya.
古菌的DNA病毒具有高度多样且往往异常复杂的形态类型。许多病毒是从地热加热的高温环境中分离出来的，这引发了关于它们起源的有趣问题，也与极端环境中生物多样性有限这一普遍观念相矛盾。在这里，我们对古菌病毒提出了一个统一的观点，并将它们视为一个特殊的群体，其形态类型和基因组与生命的其他两个域（细菌和真核生物）的DNA病毒有着根本的不同。
