Microscopia electrônica de estirpes do vírus Y da batatinha que ocorrem em São Paulo

Abstract: Sete estirpes do vírus Y da batatinha que ocorrem no Estado de São Paulo, assim, consideradas em vista de suas características, além da estirpe típica, foram examinadas ao microscópio electrônico, preparadas pelo método do exsudato ou do "dipping"'. Em tôdas as preparações foram encontradas partículas alongadas e flexíveis, cujos comprimentos normais não variavam significantemente entre si, correspondendo ao CN já descrito para êste vírus. Entretanto, notou-se tendência de uma das estirpes ser preferencialment… Show more

“…They studied some PVY isolates from Peru, inducing vein necrosis in leaves of tobacco. It took 20 years before a first official scientific report on PVY in Brazil was published in Sao Paulo State (Kitajima et al 1962) where the authors describe the virus particle morphology and the histological symptoms. During the following years, although PVY was not considered a major problem for Brazilian potato producers, attempts to discover new methods to avoid PVY infection and to find new indicator plants were carried out in Brazil.…”

“…A sua origem e a sua associação com as partículas do vírus ainda não estão perfeitamente compreendidas, ocorrendo em tecidos de plantas infetadas por praticamente todos os vírus do grupo morfológico do vírus Y da batata até aqui examinados (3,8,9,10,12,14,19,20).…”
