Pseudopezicula tracheiphila on Vitis vinifera: Microscopical studies of the infection mechanism


, : Pseudopezicula tracheiphila on Vitis vinifera: Microscopical studies of the infection mechanism. Zeitschrift fur Pflanzenkrankheiten und Pflanzenschutz 104(5): 483-491

Electron microscopical studies of Rotbrenner pathogenesis revealed that the fungus predominantly penetrates the anticlinal cell walls of the host. Appressorium formation is not required for penetration. To improve attachment to the host surface, the infection hypha forms mucous pad. As a defence reaction, secondary deposits of the cell walls of the adjacent epidermal cells were observed. After penetrating the epidermis cells, the fungus remained biotrophic.

We report here on a new principle for the detection of darbepoe...

Chronic hepatitis C (CHC) has been associated with lymphoproliferative disorders (LPD) such as mixed cryoglobulinemia syndrome (MCS), monoclonal gammopathy of undetermined significance (MGUS), and B-cell non-Hodgkin lymphoma (B-NHL). The aim of th...
