A novel negative-sense single-stranded RNA mycovirus, designated as "Magnaporthe oryzae mymonavirus 1" (MoMNV1), was identified in the rice blast fungus Magnaporthe oryzae isolate NJ39. MoMNV1 has a single genomic RNA segment consisting of 10,515 nucleotides, which contains six open reading frames. The largest open reading frame contains 5837 bases and encodes an RNA replicase. The six open reading frames have no overlap and are arranged linearly on the genome, but the spacing of the genes is small, with a maximum of 315 bases and a minimum of 80 bases. Genome comparison and phylogenetic analysis indicated that MoMNV1 is a new member of the genus Penicillimonavirus of the family Mymonaviridae.
一种新型的负义单链 RNA 真菌病毒,被命名为“稻瘟病菌 Mymonavirus 1”(MoMNV1),在稻瘟病菌分离株 NJ39 中被鉴定出来。MoMNV1 有一个由 10515 个核苷酸组成的单基因组 RNA 片段,其中包含六个开放阅读框。最大的开放阅读框包含 5837 个碱基,编码 RNA 复制酶。这六个开放阅读框没有重叠,在线性基因组上排列,但基因之间的间隔很小,最大间隔为 315 个碱基,最小间隔为 80 个碱基。基因组比较和系统发育分析表明,MoMNV1 是 Mymonaviridae 科 Penicillimonavirus 属的一个新成员。
