Characterization of a filamentous virus from Bermuda grass and its molecular, serological and biological comparison with Spartina mottle virus.
Bermuda grass with mosaic symptoms have been found in many parts of Iran. No serological correlation was observed between two isolates of this filamentous virus and any of the members of the family Potyviridae that were tested. Aphid transmission was demonstrated at low efficiency for isolates of this virus, whereas no transmission through seed was observed. A DNA fragment corresponding to the 3' end of the viral genome of these two isolates from Iran and one isolate from Italy was amplified and sequenced. A BLAST search showed that these isolates are more closely related to Spartina mottle virus (SpMV) than to any other virus in the family Potyviridae. Specific serological assays confirmed the phylogenetic analysis. Sequence and phylogenetic analysis suggested that these isolates could be considered as divergent strains of SpMV in the proposed genus Sparmovirus.
