Pathogen cells of Fusarium oxysporum f.sp. radicis-lycopersici infecting container-grown tomato plants were characterized ultrastructurally, using gold-complexed probes, chitinase and wheat germ agglutinin to localize chitin, and polyclonal antibodies to a polygalacturonase to localize this enzyme. It was isolated and purified from the pathogen growing in culture. Many fungal cells were of irregular forms (microhyphal, frondose) with modified, thin or imperceptible lucent wall layers, in which… CONTINUE READING
