Abstract

Current information on the diversity and evolution of eukaryotic RNA viruses is biased towards host lineages, such as animals, plants, and fungi. Although protists represent the majority of eukaryotic diversity, our understanding of the protist RNA virosphere is still limited. To reveal untapped RNA viral diversity, we screened RNA viruses from 30 marine protist isolates and identified a novel RNA virus named Haloplacidia narnavirus 1 (HpNV1). A phylogenetic ana-lysis revealed that HpNV1 is a new member of the family Narnaviridae. The present study filled a gap in the distribution of narnaviruses and implies their wide distribution in Stramenopiles.

首次在海洋原生动物比吉拉体内发现纳尼亚病毒

目前有关真核 RNA 病毒的多样性和进化的信息偏重于动物、植物和真菌等宿主类群。虽然原生生物占真核生物多样性的大多数，但我们对原生生物 RNA 病毒界的了解仍然有限。为了揭示尚未开发的 RNA 病毒多样性，我们对 30 个海洋原生动物分离物中的 RNA 病毒进行了筛选，发现了一种名为 Haloplacidia narnavirus 1（HpNV1）的新型 RNA 病毒。系统进化分析表明，HpNV1 是纳尼亚病毒科的新成员。本研究填补了纳尼亚病毒分布方面的空白，意味着纳尼亚病毒在石龙子中的广泛分布。
