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.
HUBÁLEK Z. (1981): A systematic survey of dimorphic and polymorphic fungi. Česká Mykologie 35(4): 209-226 (published: 1981)
abstract
Various definitions of the term dimorphism in fungi are briefly discussed and a general concept is given with a suggested morphological classification of the dimorphism. Dimorphism (and polymorphism) is delimited as an environmentally controlled reversible phenotypic duality (or plurality in the case of polymorphism) in the morphogenesis of the vegetative fungal cells, which is not restricted to pathogenic species and to the mycelial-yeast transitions only. A systematic list and an alphabetical index of the fungi exhibiting the phenomena of cellular dimorphism or polymorphism are presented.
NOVÁKOVÁ J. (1977): Wechselseitige Beziehungen zwischen den Virus- und Pilz- krankheiten bei Kulturpflanzen. Česká Mykologie 31(2): 60-68 (published: 1977)
abstract
The importance of mixed infections of cultivated plants by viruses and pathogenic fungi is analyzed both from theoretical and practical points of view. The course of root rots caused by pathogenic fungi in various virus-infected hosts is described as an example to demonstrate these relationships. The causes of the altered disease syndrome in the root system are discussed.
SAMŠIŇÁKOVÁ A. (1975): List of strains of entomogenic fungi. Česká Mykologie 29(4): 211-212 (published: 1975)
abstract
A list of strains of entomogenic fungi is provided, mostly Deuteromycetes, from the mycological collection of the Institute of Entomology, Czechoslovak Academy of Sciences. Most were isolated in Czechoslovakia, some from Cuba and Poland.
