The plant originated in the United States, where wineberry is established in the wild in the Northeast. Experimentally, WLV can be graft-transmitted to some wild Rubus spp. and to some red raspberry, black raspberry, blackberry, and blackberry-raspberry hybrid cultivars. Other red raspberry and blackberry cultivars appeared to be graft-immune. A number of commonly used herbaceous virus indicator plants, including Catharanthus roseus, several Chenopodium spp., Gomphrena globosa and Lycopersicon esculentum, can be successfully sap-inoculated with the virus by using a buffer containing 2% nicotine alkaloid. Recent studies in Scotland have suggested that WLV might be the cause of blackberry calico disease; however, plants infected with blackberry calico reacted with antisera to several Carlaviruses, whereas plants infected with WLV did not. Further work on the relationship, if any, between these two viruses needs to studied. If they are caused by the strains of the same virus, the economic importance of WLV will have been established. The virion of WLV had flexuous rod-shaped particles, about 620 × 12 nm, and did not react serologically with several potexviruses, carlaviruses, capilloviruses, or Apple chlorotic leaf spot virus. |
