Abstract
Flexuous filaments, resembling flexivirus virions, were observed in partially purified blackberry preparations showing mild virus-like symptoms. Further tests revealed the presence of a novel betaflexivirus that is phylogenetically related to foveaviruses. The putative virus-encoded proteins shared limited similarity with orthologs of known members of the genus, indicating that the virus, provisionally named Rubus canadensis virus 1 (RuCV-1), represents a novel member of the taxon. Results of a survey in several U.S. states suggest that RuCV-1 is not widespread in the blackberry germplasm.
