Abstract:
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.
摘要:
一种新型负义单链RNA分枝杆菌病毒,指定为“稻瘟病菌霉菌病毒1”(MoMNV1),在稻瘟病菌稻瘟病菌分离株NJ39中鉴定。MoMNV1具有由10,515个核苷酸组成的单个基因组RNA片段,其中包含六个开放阅读框架。最大的开放阅读框包含5837个碱基并编码RNA复制酶。六个开放阅读框没有重叠,在基因组上呈线性排列,但是基因的间距很小,最大为315个碱基,最小为80个碱基。基因组比较和系统发育分析表明,MoMNV1是Mymonaviridae家族青霉菌属的新成员。
