MINARČIC P., JANISCH R., PAULECH C. (1989): Ultrastructure representation of the powdery mildew conidium by the freezeetching method. Česká Mykologie 43(3): 166-168 (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.
