A virus that has properties consistent with inclusion in the virus family Narnaviridae was described in Phytophthora infestans, the oomycete that caused the Irish potato famine. The genome of phytophthora infestans RNA virus 4 (PiRV-4) is 2,984 nt with short complementary terminal sequences and a single open reading frame predicted to encode an RNA-dependent RNA polymerase (RdRp) most closely related to saccharomyces cerevisiae narnavirus 20S (ScNV-20S) and ScNV-23S, the members of the genus Narnavirus, family Narnaviridae. This report constitutes the first description of a member of the family Narnaviridae from a host taxon outside of the kingdom Fungi.
一种具有纳 RNA 病毒科特性的病毒在引起爱尔兰马铃薯饥荒的卵菌疫霉（Phytophthora infestans）中被描述。疫霉马铃薯 RNA 病毒 4（PiRV-4）的基因组为 2984 个核苷酸，具有短的互补末端序列和一个单一的开放阅读框，预测编码一个 RNA 依赖性 RNA 聚合酶（RdRp），与酿酒酵母纳 RNA 病毒 20S（ScNV-20S）和 ScNV-23S 最为密切相关，这两种病毒是纳 RNA 病毒科纳 RNA 病毒属的成员。本报告首次描述了真菌界以外的宿主分类群中的纳 RNA 病毒科的一个成员。
