Summary: | The ultrastructure of intercellular hyphae and D‐hati‐storia of P. recondita f.sp. tritici, and the host response to haustorial invasion, was investigated. The intercellular hyphae share common characteristics with those of other uredial stage rust fungi. Anastomosis was observed between intercellular hyphae. Two nucleoli were frequently observed in a single nucleus in the haustorium, indicating possible nuclear fusion between the two nuclei in D‐haustoria of this fungus. The close association of host organelles, such as the nucleus, Golgi bodies, endo‐plasmic reticulum, vesicles and mitochondria, with the developing haustorium, is described.
Zusammenfassung
Untersucht wurde die Feinstruktur der interzellulären Hyphen und der D‐Haustorien von Puccinia recondita f.sp. tritici sowie die Reaktion des Wirtes auf die Haustorienbildung des Pilzes. Die interzellulären Hyphen ähneln denjenigen anderer uredosporenbildender Rostpilze. Zwischen ihnen kam es zu Anastomosen. In den Haustorien wurden häufig Kerne mit zwei Nukleoli beobachtet, was möglicherweise auf einem Verschmelzen der beiden Kerne im D‐Haustorium des Pilzes beruht. Die räumliche Nähe von Wirtsorganellen, zum Beispiel des Kerns, des Golgi‐Apparats, des endoplasmatischen Retikulums, der Vesikel und der Mitochondrien, zu dem sich entwickelnden Haustorium wird beschrieben. |
