Abstract
The ultrastructural features of wheat interacting with stripe rust fungus were studied by using typical wheat cultivars of high-temperature resistance to rust as experimental material. The results demonstrated that the expression of high-temperature resistance resulted in the marked changes both in ultrastructures of fungus and that of host mesophyll cells, forming infection-induced defense structure and materials. The fungal hyphae of stripe rust were inhibited, organelles vesiculated and rapidly disintegrated or collapsed. The developments of haustorial mother cells and haustoria were retarded, malformed, and necrotized. Extrahaustorial membrane wrinkled, stained more deeply, wrinkled, and perforated. Membranes of host mesophyll cells had marked pathological changes, organelles disintegrated, cytoplasm condensed, plasmalemma invaginated, and eventually the whole cell disintegrated and necrotized. Besides from the above-mentioned typical characters of hypersensitive reaction, the host cells also produced defense structure in cell walls and secondary metabolic materials. Finally, the defense reactions of high-temperature disease-resistant wheat cultivars are compared and contrasted with the common disease-resistance of low reaction type.
