Detection of Varicosavirus and Ophiovirus in lettuce associated with lettuce big-vein symptoms in Brazil
Fitopatologia Brasileira 30 (4), 416-419
Abstract: During surveys undertaken from 1998 to 2003 in the major vegetable growing areas of the city of São Paulo green belt, lettuce (Lactuca sativa) and endive (Cichorium endivia) plants were observed, which showed chlorotic thickening of foliar veins, defective growth and, in some cases, failure to form complete heads. Biological and serological [DAS-Enzyme linked immunosorbent assay (Elisa)] tests together with electron microscope observations, revealed the presence of Lettuce big-vein virus and Mirafiori lettuce virus, in these plants both responsible for the lettuce big-vein syndrome.
