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.Em levantamentos realizados entre 1998 e 2003, nas principais regiões produtoras de alface (Lactuca sativa) e escarola (Cichorium endivia) no cinturão verde de São Paulo, foram observados sintomas de espessamento de nervuras foliares, clorose, crescimento irregular e ausência de formação da cabeça. Por meio de testes biológicos, DAS-Enzyme linked immunosorbent assay (Elisa) e microscopia eletrônica de transmissão constatou-se a presença do Lettuce big-vein associated virus e Mirafiori lettuce virus, responsáveis pela síndrome do espessamento clorótico das nervuras da alface ("lettuce big-vein").
