“…BRV infects black currants ( Ribes nigrum ), cultivated and wild red currants ( R. rubrum and R. spicatum , respectively) and alpine currants ( R. alpinum ). In the wild, BRV has only been detected in association with BRD (Adams and Thresh, 1987; Cropley et al ., 1964; Krczal, 1976). Identification of BRD has been hampered by distinguishing at least two forms of the disease: the common European form and the severe form, restricted to Scandinavia, Eastern Europe and the countries of the former Soviet Union in its natural distribution (Jones, 2000).…”

SUMMARYTaxonomy: Black currant reversion virus (BRV) is the first identified mite-transmitted member of the genus Nepovirus (family Comoviridae ). A few systematic studies have been performed to compare virus isolates from different geographical locations.Physical properties: Purified preparations contain two closely sedimenting centrifugal components (B and M for RNA1 and RNA2, respectively) at varying ratios, and occasionally a T component (for satellite RNA). The BRV capsids have a diameter of 27 nm and they are putatively composed of 60 copies of a single species of capsid (coat) protein assembled in an icosahedral lattice. Diluted plant sap loses its infectivity within 1 day at 20 ° C and in 4-8 days at 4 ° C.Hosts: The natural host range of BRV is limited; it infects black currant ( Ribes nigrum L.) and some related Ribes species. The transmission of the virus is by the eriophyid gall mite of black currant ( Cecidophyopsis ribis ). A number of herbaceous plants can be infected experimentally. BRV is the agent of black currant reversion disease (BRD), which is economically the most significant virus disease in Ribes species. BRV and BRD occur widely in locations where black currant is cultivated commercially.

“…These were 'Silvergieters Schwarze' (Krczal 1976), which had been imported into New Zealand in 1963 (HortResearch plant quarantine records), and 'Ojebyn' (Bremer & Heikinheimo 1979) which had been imported in 1979 (HortResearch plant quarantine records), hi addition, the cultivar 'Kentish Hero', which has been present in New Zealand since 1899 (Anon. 1899) and plants of which had shown particularly severe foliage symptoms of reversion in a South Canterbury planting, was similarly evaluated as an indicator.…”

An evaluation of several black currant (Ribes nigrum L.) cultivars recommended or suggested as indicators for the reversion disease, showed 'Baldwin' to be the most sensitive. 'Kentish Hero' and 'Silvergieters Schwarze' were almost as sensitive as 'Baldwin', but 'Ojebyn' did not express definitive symptoms. A virulent strain of reversion found in the cultivar 'Kentish Hero' appears similar to the V 1 strain reported in England. Moderate, and possibly mild, strains occurred in several other cultivars. However, the severe "R" form of the disease causing the split sepal symptom of black currants in Scandinavia and Eastern Europe does not appear to be present in New Zealand. Surveys in 1990Surveys in , 1991Surveys in , and 1996 of commercial properties growing black currants in the South Island showed that reversion was present in several plantings in South Canterbury and Otago, and was widespread in Southland plantings. A low incidence of reversion in Nelson is thought to have been eliminated by the removal of infected plants. North Canterbury plantings remain free from infection, but infection has appeared at two locations in mid Canterbury. H98017 Received 30 March 1998; accepted 16 June 1998Spread of infection between properties was initially caused through the inadvertent use of infected propagation material, and further spread within properties by the gall mite (Cecidophyopis ribis Westw.) vector. The use of gall mite resistant cultivars appears to be the only effective means for the control of reversion.

“…Positive transmission ofreversion was obtained from the cultivars 'Daniel's Late September' from Otago, and 'Cotswold Cross' and 'Seabrook's Black' from Southland. Subsequently, using the same sources ofinfection, graft-transmission was obtained in the cultivars 'Silvergieters' and 'Ojebyn', both of which have been found to be sensitive to reversion overseas (Krczal 1976;Bremer & Heikinheimo 1979).…”

The presence in New Zealand of the reversion disease ofblack currants was demonstrated by the development oftypical symptoms in susceptible cultivars after graft inoculation. Reversion appears to be responsible for the serious crop losses occurring in Otago and Southland regions. It is not restricted to those areas, but occurs at a low incidence in Canterbury and Nelson regions. Spread has occurred through the use of infected cuttings during propagation, and probably also by the gall mite vector. Red currant vein banding disease was detected in several red currant cultivars by graft inoculation to red currant seedlings, and to the indicator B1385/81, but is of low incidence. The disease boysenberry decline, possibly caused by a mycoplasma-like organism, occurs in the northern half of the North Island. During the 1980s it appeared to be spreading rapidly until the removal of most infected plantings greatly reduced its incidence. The boysenberry leatbopper is a possible vector, but in controlled glasshouse and field trials natural spread of the disease by this agent has notbeen observed. A leaf variegation symptom, widespread in several black currant cultivars in New Zealand, may be a non-transmissible syndrome.
