Interpretive Summary:

Technical Abstract: In the blackberry cultivar Himalaya Giant naturally infected in England, CLRV is reported to cause chlorotic mottling and line patterning in leaves. Infected plants are stunted and may be killed. In three red raspberry cultivars naturally infected by CLRV in New Zealand, infected plants had stunted, distorted leaves with severe chlorotic mottle and ring and line patterns. Resistance or immunity to CLRV in Rubus has not been reported. CLRV is a member of subgroup C of the Nepovirus genus, a single-stranded bipartite RNA virus with isometric particles ~28 nm in diameter. Even though a member of the Nepoviruses, a nematode vector has not been identified. It is transmitted by pollen in walnut and this could well be a route of transmission in Rubus. A number of antisera against CLRV isolates from different hosts have been prepared, and although cross-recognizable, they tend to be somewhat serologically distinct according to host source. The raspberry isolates of CLRV in New Zealand were all detected by antisera against CLRV from American dogwood. There are multiple serotypes; however, detection of all known serotypes can be accomplished by RT-PCR with selected primers.
