Comparação electrono-microscópica dos tecidos de plantas infetadas por diferentes estirpes do vírus Y da batata que ocorrem no Estado de São Paulo

Abstract: Exames, ao microscópio electrônico, de secções ultrafinas de tecidos, principalmente foliar, de plantas de diversas espécies, infetadas por uma das 17 estirpes do vírus Y da batata que ocorrem no Estado de São Paulo, mostraram: a)Ocorrência de inclusões citoplasmáticas, lamelares, do tipo descrito por Edwardson, e ocasional presença¹, no citoplasma, de partículas similares àquelas encontradas in vitroe em tecidos de plantas infetadas por qualquer uma das estirpes estudadas; b)aparecimento esporádico de agregad… Show more

“…Differences in morphology of cylindrical inclusions have been used to distinguish viruses within the PVY-group (Edwardson, Purcifull & Christie, 1968;Hiebert et al 1971 ;Purcifull et al 197o). That strains of the same PVY-group virus induce similar or identical inclusions is indicated by comparisons of strains of PVY (Montenegro et aL 1968), of BYMV (de Camargo, Kitajima & Costa, 1968;Cousin et al 1969;Kamei et al 1969;Weintraub & Ragetli, 1966) and of tobacco etch virus (Matsui & Yamaguchi, 1964;Rubio-Huertos & Hidalgo, 1964 ). The cylindrical inclusions induced by the F, W and K isolates of BYMV are very similar, and they are also very similar to those induced by previously described BYMV strains.…”
