BRILLOVÁ D., ŠUŤÁKOVÁ G. (1984): Viruslike particles in hyphae of parasitic fungus Cercospora beticola Sacc. Česká Mykologie 38(4): 193-196 (published: 15th November, 1984)
abstract
In the present paper we summarize the results of electron microscope investigation of the hyphae of three singlespore isolates of Cercospora beticola and a sterile mutant. In ultrathin sections of hyphal cells we have found two types of viruslike particles of spherical shape, 30—35 and 50—55 nm in diameter. They were dispersed in the cytoplasm and occasionally in the vacuoles as well. Viruslike particles of both types occurred together in the hyphal cells of the strain Mss2, whereas the hyphal cells of strain PR13 contained viruslike particles only one dimension, i.e. there were cells containing 30—35 nm and others 50—55 nm viruslike particles. In the infected cells we observed changes of mitochondria, the occurrence of lamellar structures, changes of cell walls leading to the disruption and liberation of viruslike particles from the cells. The sporulation of infected strains was considerably lower than in healthy one.
