Interpretive Summary:

Technical Abstract: Raspberry bushy dwarf virus (RBDV) occurs naturally worldwide in many Rubus species and cultivars. In North America, it naturally infects many red raspberry, black raspberry, blackberry and blackberry-raspberry hybrid cultivars. RBDV also occurs in wild R. idaeus L. var. strigosus, R. occidentali., R. parviflorus Nutt., and R. leucodermis. Experimental hosts (by graft inoculation) include Cydonia oblonga, Fragaria vesca and seven additional Rubus spp. and (by sap inoculation) to several herbaceous indicator hosts. It has been reported from R. multibracteatus seedlings grown from seed collected in China. Until recently, RBDV was only known to infect Rubus spp. naturally, but has been reported in grapevine in Slovenia in 2006. The virion of RBDV is quasi-isometric (33 nm), and is the sole member of the genus Idaeovirus. A virus from citrus that has been partially sequenced showed significant nucleotide sequence identity with RBDV. Polyclonal and monoclonal antibodies have been produced against RBDV. Antisera against red raspberry isolates of RBDV recognize this virus in all hosts tested, but RBDV from black raspberry is a distinct serotype. Enzyme-linked immunosorbent assay (ELISA) is now the method of choice for the detection of the virus. Transgenic red raspberry have been developed with resistance to RBDV, but have not been commercialized. There are a number of cultivars that are immnune to the type strain of RBDV, but all are susceptible to the resistance breaking strain reported in Europe.
