Here we report an occurrence of Snake River alfalfa virus (SRAV) in Washington state, USA. SRAV was recently identified in alfalfa (Medicago sativa L.) plants and western flower thrips in south-central Idaho and proposed to be a first flavi-like virus identified in a plant host. We argue that the SRAV, based on its prevalence in alfalfa plants, readily detectable dsRNA, genome structure, presence in alfalfa seeds, and seed-mediated transmission is a persistent new virus distantly resembling members of the family Endornaviridae.
在这里，我们报告了美国华盛顿州蛇河紫花苜蓿病毒（SRAV）的发生情况。SRAV 最近在爱达荷州中南部的紫花苜蓿（Medicago sativa L.）植物和西部花蓟马中被鉴定出来，并被提议成为在植物宿主中鉴定出的第一个类似黄病毒。我们认为，基于其在紫花苜蓿植物中的普遍性、易于检测的双链 RNA、基因组结构、在紫花苜蓿种子中的存在以及通过种子介导的传播，SRAV 是一种与内罗病毒科成员具有远缘关系的持久性新病毒。
