Abstract

A novel mitovirus, tentatively designated as “Fusarium oxysporum mitovirus 2” (FoMV2), was isolated from the pathogenic Fusarium oxysporum f. sp. ginseng strain 0414 infecting Panax ginseng. The complete genome of FoMV2 is 2388 nt in length with a GC content of 30.57%. It contains a large open reading frame (ORF) encoding a putative RNA-dependent RNA polymerase (RdRp) of 713 amino acids with a molecular weight of 83.05 kDa. The sequence identity between FoMV2 and Botrytis cinerea mitovirus 8 and Fusarium verticillioides mitovirus 1 was 87.94% and 77.85%, respectively. Phylogenetic analysis showed that FoMV2 belongs to the genus Unuamitovirus in the family Mitoviridae. To the best of our knowledge, this is the first report of an unuamitovirus isolated from F. oxysporum f. sp. ginseng causing ginseng root rot.
