Abstract:
Blackberry viruses are pervasive, decreasing growth, yield, and plant longevity. In a quest to identify viruses associated with blackberry yellow vein, a disease caused by virus complexes, a new double-stranded DNA virus, referred to as blackberry virus F (BVF), a putative member of the genus Badnavirus, family Caulimoviridae, was identified. The virus was found in both cultivated and wild blackberry samples collected from several states in the southern United States. Population structure, host range, and association with disease symptoms were assessed. As BVF integrates into the plant genome, it affects the production of virus-free propagation material, the cornerstone for certification programs.
