摘要： Fusarium oxysporum is a cosmopolitan plant pathogen that causes fusarium wilt and fusarium root rot in many economically important crops. There is still limited information about mycoviruses that infect F. oxysporum. Here, a novel mitovirus tentatively named "Fusarium oxysporum mitovirus 1" (FoMV1) was identified in F. oxysporum strain B2-10. The genome of FoMV1 is 2,453 nt in length with a predicted AU content of 71.6% and contains one large open reading frame (ORF) using the fungal mitochondrial genetic code. The ORF putatively encodes an RNA-dependent RNA polymerase (RdRp) of 723 aa with a molecular mass of 84.98 kDa. The RdRp domain of FoMV1 shares 29.01% to 68.43% sequence identity with the members of the family Mitoviridae. Phylogenetic analysis further suggested that FoMV1 is a new member of a distinct species in the genus Mitovirus.
