Abstract

A novel single-stranded (+ss) RNA mycovirus, designated as "Magnaporthe oryzae botourmiavirus 14" (MoBV14), was identified in the rice blast fungus Magnaporthe oryzae isolate ES155. The viral genome is 2,336 nucleotides in length and contains a single open reading frame (ORF) that is predicted to encode an RNA-dependent RNA polymerase (RdRp). Genome sequence comparisons and phylogenetic analysis indicated that MoBV14 is a new member of the genus Gammascleroulivirus in the family Botourmiaviridae.

来自稻瘟病真菌 Magnaporthe oryzae ES155 分离物的一种新型甘马氏硬核病毒的分子鉴定
从稻瘟病菌Magnaporthe oryzae分离株ES155中鉴定出一种新的单链(+ss) RNA分枝病毒,命名为“Magnaporthe oryzae botourmivirus 14”(MoBV14)。病毒基因组长度为2336个核苷酸,包含一个开放阅读框(ORF),预计其编码RNA依赖性RNA聚合酶(RdRp)。基因组序列比较和系统发育分析表明,MoBV14是肉毒杆菌科Gammascleroulivirus属的新成员。

期刊介绍: Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
