Radish Mosaic Virus (1) (RaMV, a comovirus) (Synonym: Radish enation mosaic virus) is know to infect almost all crucifers. Main affected crops are different cruciferous plants such as rape, mustards, cabbage, arugula (Eruca sativa), and false flax or gold-of-pleasure (Camelina sativa). Symptoms include mosaic, ringspots, leaf distortion, veinal necrosis and systemic necrosis. Infected radish plants may show leaf venations. In cauliflower and cabbage symptoms appear as chlorotic and necrotic lesions along with a mosaic. The virus is transmitted by various beetles and is present in both crop plants and weeds, which serve as reservoirs for spreading of the disease. The virus has been found in Japan, Europe, North Africa and USA.
The reagents were made against a Czech virus isolate (designated RaMV-1) of winter turnip rape (3). They react specifically with RaMV in DAS-ELISA (2). All isolates of the different “strain groups” are detected in DAS-ELISA (2), even though serological variability has been demonstrated by gel diffusion tests (4). Test samples are homogenized 1:20 (w/v) in extraction buffer «General» (Art. No. 110120). The product was developed in cooperation with the Institute of Plant Molecular Biology, Ceske Budejovice, Czech Republic.
