Název v původním jazyce
The role of plant cell in host-pathogen interactions: Lactuca spp. Bremia lactucae.
Popis výsledku v původním jazyce
Gene-for-gene based interactions in model system of Lactuca spp.-Bremia Lactucae represent a wide range of host-pathogen relationships. Microscopical studies of infection course and reactions of host genotypes with different mechanisms of compatibility/incompatibility revealed significance of initial stages in establishment of relation between host and parasite. Incompatibility is mostly expressed as hypersensitive reaction. Cytoskeleton components reorganization may be involved in blocking of fungus penetration. Polymerized state of microfilaments in host cell is necessary for development of fungal infection structures. Biochemical and cytochemical study of oxidative stress showed changes in activity of peroxidase and catalase, formation of hydrogen peroxide and deposition of phenolic compounds. These processes well correspond with resistance expression. On the other hand, formation of callose attending pathogenesis is not related to incompatibility in studied reaction.
