KOKEŠ P., MÜLLER J. (2004): Checklist of downy mildews, rusts and smuts of Moravia and Silesia. [plant-parasitic fungi, occurrence, regions of the Czech Republic, Peronosporales, Sclerosporales, Urediniomycetes, Ustilaginomycetes] Czech Mycology 56(1-2): 121-148 (published: 12th August, 2004)
abstract
This checklist includes 736 taxa of downy mildews, rusts and smuts reported from Moravia and Czech Silesia, Czech Republic. There are 114 species parasiting oncrops and other cultivated plants. The list includes the frequency of occurrence, i. e. commonness or rarity of individual taxa. The work is based on literature data.
MOLITORIS H.P. (1995): Fungi in biotechnology. Past, present, future. [Fungi, biotechnology, past, present, future] Czech Mycology 48(1): 53-65 (published: 16th May, 1995)
abstract
From multiple uses of fungi in early historic times, “early biotechnological processes” developed. Fungi were used here already e.g. for production of cheese, bread, wine, beer and other foodstuff. Based on these processes, fungi today have become one of the most important group of organisms in modern technology, where food, fodder and various metabolites such as antibiotics, enzymes, steroids etc. are produced on an industrial scale. An equally important role of fungi in biotechnology is also to be expected for the future where - in addition to existing uses - fungi will be increasingly used employing modern methods such as genetic engineering and will also new applications as in pollution control, biological control of pests, microbial leaching and even biotechnology.
BRILLOVÁ D., SLADKÁ O. (1989): Transmission of virus-like particles from the infected into the healthy strains of Cercospora beticola Sacc. Česká Mykologie 43(3): 155-165 (published: 21st August, 1989)
abstract
The paper deals with the ultrastructure of the conidia of powdery mildew (Erysiphe graminis f. sp. hordei Marchal) using the freeze-etching technique. Cross fractures through whole conidia exposed the cell wall and faces of the plasma membrane bearing invaginations. In addition, structural details of the conidium internal organization were recognized. The nuclear membrane showed numerous pores scattered over the nuclear surface. Numerous mitochondria, small vesicles and glycogen accumulated along the conidium periphery. The results obtained with Erysiphe graminis conidia prove the advantages of the freeze-etching method over the conventional fixation procedures for fungal conidia.
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.
ČAČA Z. (1982): Present trends in the world phytopathological research. Česká Mykologie 36(2): 65-71 (published: 15th May, 1982)
abstract
Vararia granulosa (Fr.) Laurila is a name which cannot be applied to the fungus for which it is now commonly used. Fries (1838, 1874) considered the element representing our Vararia only a marginal part of his broad concept of Grandinia granulosa (Pers. ex Fr.) Fr. As there is no legitimate name for the fungus in question, Vararia borealis Pouz. spec. nov. is proposed for it here.
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.
