Interpretive Summary:

Technical Abstract: Blackberry yellow vein disease, with symptoms of vein clearing, yellow mottling, ringspots and plant decline has been observed in blackberry in the southeastern United States since about 2000. At least six viruses have been identified by cloning and sequencing of double-stranded RNA from diseased plants. Blackberry yellow vein associated virus (BYVaV, a crinivirus) appears to be present in most if not all symptomatic plants along with at least one or more of the other five viruses. A novel potyvirus lacking the DAG triplet and containing an alkB domain is found together with BYVaV in symptomatic plants from Arkansas but has not been detected in other areas. Blackberry virus X (Flexiviridae) has been detected in symptomatic plants along with BYVaV in North and South Carolina, Arkansas and in Mississippi. Beet pseudo yellows virus has been detected in blackberries from North and South Carolina. A novel putative allexivirus (BlVE) has been identified from symptomatic plants in Mississippi, though the extent of this virus is not yet known. Several symptomatic plants from Arkansas also contained an insect-like virus in addition to BYVaV and BVY. Tobacco ringspot and Raspberry bushy dwarf viruses have also been detected in the region and they may also be involved in disease symptoms when they occur in mixed infections with BYVAV. The current understanding of the blackberry yellow vein disease is that it is caused by BYVaV, in mixed infections with at least one or more of the above viruses.
