Interpretive Summary:

Technical Abstract: During routine graft indexing at HCRL (Corvallis, Oregon, a ‘Glen Clova’ plant that originated in Europe induced severe symptoms in indicator plants, causing mottling, epinasty and apical necrosis. Testing for all Rubus viruses with available detection tests failed to identify a known virus in the plant. DsRNA was extracted and cloned. Sequence analysis revealed the presence of three novel viruses in the plant designated as Glen Clova virus -1,-2 and -3 (GC-1, -2, -3). GC-1 is a novel closterovirus with sequence similarity to Citrus tristeza virus. GC-2 is a member of the family Flexiviridae and shares greatest similarity with the unassigned members of the family infecting rosaceous hosts. GC-3, a unique plant virus, belongs to the Dicistroviridae, a family of picorna-like insect viruses and is similar to a novel virus identified recently in strawberry (Tzanetakis and Martin, unpublished data). The detection protocols developed have verified the presence of the viruses in other Rubus plants that originated in the United States Transmission tests are currently underway.
