Abstract

A novel single-stranded (+ss) RNA mycovirus, designated as "Magnaporthe oryzae narnavirus 2" (MoNV2), was identified in the rice blast fungus Magnaporthe oryzae isolate NJ471. MoNV2 has an RNA genome of 3,086 nucleotides, which contains a single open reading frame (ORF) that is predicted to encode an RNA-dependent RNA polymerase (RdRp). Genome sequence comparisons and phylogenetic analysis suggested that MoNV2 is a new member of the genus Narnavirus of the family Narnaviridae. The 5' and 3' ends of the MoNV2 genomic RNA are complementary to each other, potentially forming a panhandle structure.

稻瘟病菌Magnaporthe oryzae分离株NJ471具有反向互补末端的新型narnavvirus全基因组序列。

从稻瘟病菌Magnaporthe oryzae分离株NJ471中鉴定出一种新的单链（+ss） RNA分枝病毒，命名为“Magnaporthe oryzae narnavirus 2”（MoNV2）。MoNV2具有3086个核苷酸的RNA基因组，其中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，MoNV2是纳纳病毒科纳纳病毒属的新成员。MoNV2基因组RNA的5‘和3’端是互补的，可能形成一个长柄结构。

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.
