A new virus was identified in blackberry plants exhibiting leaf mottling, chlorotic ringspots and curved midribs, symptoms associated with blackberry yellow vein disease (BYVD). The genome of the new virus, provisionally named blackberry leaf mottle-associated virus (BLMaV), was characterized and phylogenetic analysis revealed its close relationship to recognized members of the genus Emaravirus. BLMaV was transmitted by a yet to be described eriophyid mite species, further reinforcing its placement in the genus. Detection protocols were developed and used to determine the presence of the virus in plants collected from several areas in the U.S.A. The incidence of BLMaV was greater than 40% in BYVD-affected material.
在表现出叶片斑驳、褪绿环斑和中脉弯曲症状的黑莓植株中发现了一种新病毒，这些症状与黑莓黄脉病（BYVD）相关。对这种新病毒的基因组进行了表征，该病毒暂命名为黑莓叶斑驳相关病毒（BLMaV），系统发育分析显示它与已确认的埃玛拉病毒属成员关系密切。BLMaV由一种有待描述的瘿螨物种传播，这进一步证明了它在该属中的地位。开发了检测方法并用于确定从美国几个地区采集的植物中该病毒的存在情况。在受BYVD影响的材料中，BLMaV的发病率超过40%。
