Abstract / Bemerkung
The complete genome of a novel mycovirus, named Rhizoctonia solani flexivirus 1 (RsFV-1), which infects an avirulent strain of Rhizoctonia solani AG 2-2 IV, was sequenced and analyzed. Its RNA genome consists of 10,621 nucleotides, excluding the poly-A tail, and encodes a single protein of 3477 amino acids. The identification of conserved motifs of methyltransferase, helicase and RNA-dependent RNA polymerase revealed its relatedness to members of the alphavirus-like superfamily of positive-strand RNA viruses. Phylogenetic analysis of these fused domains suggested that this virus should be assigned to the order Tymovirales. The recently described Fusarium graminearum deltaflexivirus 1 was found to be its closest relative. However, the whole genome, as well as the encoded protein of RsFV-1, is larger than that of other known members of the order Tymovirales, and unlike all other viruses belonging to this order, its methyltransferase domain is not located at the N-terminus of the replicase. Although genome diversity, as a result of recombination and gene loss, is a well-documented trait in members of the order Tymovirales, no related virus with a comparable genome alteration has been reported before. For these reasons, RsFV-1 broadens our perception about genome plasticity and diversity within the order Tymovirales.
