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., SLADKÁ O., PETERKOVÁ I. (1988): Respiration of the wild strain and the mutants of Cercospora beticola Sacc. Česká Mykologie 42(2): 97-104 (published: 10th May, 1988)
abstract
Light non-pathogenic mutants of Cercospora beticola exhibit a markedly increased respiration compared to pathogenic dark-grey wild strains as well as to non-pathogenic mutants having a light air mycelium and dark substrate. The increased respiration rate of light non-pathogenic mutants is discussed with respect to increased potassium content in their mycelium and donor-acceptor properties of quinones in the respiration process. A viral infection is analyzed in the group of wild strains.
