title: [Ultrastructural basis of biotrophic relationships between brown rust fungus and common wheat].
abstract: The ultrastructural research of relationships between common wheat and brown rust fungus Puccinia triticina demonstrated that the biotrophy was based on the induction of plant cytoplasmic aggregate organization, nuclear migration to haustorium and stimulation of mesophyll cell metabolism. Resistant reactions in the form of hypersensitivity and depositions on plant cell walls were suppressed up to fungal sporogenesis. Cytoplasmic reorganization and nuclear taxis to haustorium were not registered in the epidermal and vascular bundle sheath cells.
