Members of the genus Emaravirus are plant viruses transmitted by eriophyoid mites. The emaravirus genome consists of multiple, negative-sense, single-stranded RNA segments, that have been shown to be highly divergent. Recent studies have revealed that emaraviruses are associated with long-recognized diseases of world important crops such as fig mosaic disease or sterility mosaic disease of pigeon pea. Furthermore, along with the popularization of deep sequencing technologies, new putative members of emaraviruses have been reported year by year. This paper presents an overview of agricultural damages caused by emaraviruses worldwide and characteristics of their genomic RNAs and proteins. In addition, our research project to prevent a disease of a herb crop (shiso, Perilla frutescens) caused by Perilla mosaic virus, a putative emaravirus recently identified in Japan, is outlined.
细病毒属的成员是由瘿螨传播的植物病毒。细病毒基因组由多个负义单链RNA片段组成，这些片段已被证明具有高度的差异性。最近的研究表明，细病毒与世界重要作物的一些早已被认知的病害有关，如无花果花叶病或木豆不育花叶病。此外，随着深度测序技术的普及，每年都有新的疑似细病毒成员被报道。本文概述了细病毒在全球范围内造成的农业损害及其基因组RNA和蛋白质的特征。此外，还概述了我们预防一种草本作物（紫苏，Perilla frutescens）病害的研究项目，该病害由紫苏花叶病毒引起，紫苏花叶病毒是最近在日本发现的一种疑似细病毒。
