摘要：

A novel partitivirus, Fusarium commune partitivirus 1 (FcoPV1), was identified in Fusarium commune strain CP-SX-3 isolated from diseased roots of strawberry with symptoms of root rot. The complete genome of FcoPV1 comprises three double-stranded RNAs (dsRNAs): dsRNA1 (1,825 nt), dsRNA2 (1,592 nt), and dsRNA3 (1,421 nt). dsRNA1 contains a single open reading frame (ORF1) encoding an RNA-dependent RNA polymerase (RdRp), and dsRNA2 contains a single ORF (ORF2) encoding a coat protein (CP). dsRNA3 is a possible satellite RNA that does not appear to encode a known protein. BLASTp analysis revealed that RdRp (86.59%) and CP (74.13%) encoded by the two ORFs (ORF1 and ORF2) had the highest sequence similarity to their counterparts in Fusarium equiseti partitivirus 1 (FePV1). Phylogenetic analysis based on the complete amino acid sequence of RdRp suggested that FcoPV1 should be considered a member of a new species in the proposed genus "Zetapartitivirus" within the family Partitiviridae. To the best of our knowledge, this is the first report of a zetapartitivirus infecting phytopathogenic F. commune.
