苜蓿矮缩病是威胁阿根廷苜蓿生产的一种重要的突发性病害，可能由混合病毒感染的协同作用引起。对阿根廷中部地区的患病苜蓿植物样本进行深度测序，鉴定出一种在序列和基因组结构上类似于Enamoviruses的新病毒基因组。系统发育分析表明该病毒为黄病毒科Enamovirus属的新成员。该病毒暂时被命名为“苜蓿痘病毒1”（AEV-1）。AEV-1基因组序列的可用性将使得有可能评估该病毒的遗传变异性，并构建感染性克隆以研究其在苜蓿矮化病中的作用。
Alfalfa dwarf disease, probably caused by synergistic interactions of mixed virus infections, is a major and emergent disease that threatens alfalfa production in Argentina. Deep sequencing of diseased alfalfa plant samples from the central region of Argentina resulted in the identification of a new virus genome resembling enamoviruses in sequence and genome structure. Phylogenetic analysis suggests that it is a new member of the genus Enamovirus, family Luteoviridae. The virus is tentatively named "alfalfa enamovirus 1" (AEV-1). The availability of the AEV-1 genome sequence will make it possible to assess the genetic variability of this virus and to construct an infectious clone to investigate its role in alfalfa dwarfism disease.
