Idaeovirus is a genus of positive-sense ssRNA viruses that contains one species: Raspberry bushy dwarf virus (RBDV). Although the genus does not belong to any family or order, it has been proposed as a member of the family Bromoviridae due to similarities to members of that family. RBDV has two host-dependent clades: one for raspberries; the other for grapevines. Infections are a significant agricultural burden, resulting in decreased yield and quality of crops. RBDV has a synergistic relation with Raspberry leaf mottle virus, with co-infection greatly amplifying the concentration of virions in infected plants. The virus is transmitted via pollination with RBDV-infected pollen grains that first infect the stigma before causing systemic infection.
