Interpretive Summary:

Technical Abstract: Blackberry yellow vein disease causes devastating symptoms and losses in blackberry in the south and southeastern United States. Blackberry yellow vein associated virus (BYVaV) has been identified as the putative causal agent of the disease, but the identification of latent infections of BYVaV led to the investigation of additional agents involved in symptomatology. A potyvirus has been identified in blackberry plants also infected with BYVaV. The relation of the virus designated as Blackberry virus Y (BVY) with Bramble yellow mosaic virus, the only other potyvirus known to infect Rubus was investigated. The complete nucleotide sequence revealed that BVY is the largest potyvirus sequenced to date. BVY is the first potyvirus to encode an AlkB domain. The virus has minimal sequence similarities with known members of the family and should be considered a member of a novel genus in the Potyviridae. Detection protocols developed verified the presence of the virus in several blackberry plants, but it is not the causal agent of blackberry yellow vein disease since several symptomatic plants were not infected with the virus.
