Zusammenfassung

Germ tubes of Uromyces fabae differentiated into appressoria which were deliminated either by one or two septa. These appressoria developed rapidlyon artificial membranes as well as on leaf surfaces.
Fluorescein-conjugated wheat germ aggJutinin (WGA) bound strongly tO the germ tube walls of U. fabae and its binding ability did not differ significantly in 3, 5 and 7 hold germ tubes. The binding of WGA was less on the appressorium. Measurement of fluorescence with a lnicroscope photometer revealed two times more binding sites on germ tube walls than on appressoria. No binding of WGA was noticed on substomatal vesicles and infection hyphae. The binding of WGA was completely inhibited by preincubation with hydrolysate of chitin. Biflding patterns of other Jectins were quite different. Canavalia ensiformis lectin did not bind tO any structure, the Jectins of Griffonia simplicifolia and Lotus tetragonolobus bound weakly to all structures, the lectins of Phaseolus vulgaris and Arachis hypogaea bound only tO substomatal vesicles and infection hyphae, and the Ricinus communis lectin bound only tO the infection hyphae. Based on these observations it appears that infection structure surface of U. fabae, besides having chitin as a component, also contain some other carbohydrates such as galactOse and fucose.

Zusammenfassung in einer weiteren Sprache

Die Keimschläuche von Uromyces fabae differenzierten einmal die üblichen, endständigen Appressorien und solche mit 2 Septen aus. Diese Appressorien entwickelten sich auf künstlichen Membranen und auf der Blattoberfläche.
Fluorescein-markiertes Weizenkeimlektin (WGA) wurde von den Keimschläuchen ohne Rücksicht auf deren Alter gebunden. Mit dem MikroskopphotOmeter wurde deutlich, daß die Appressorien jedoch nur halb so viele Bindungsstellen wie die Keimschläuche für dieses Lektin besitzen. Ein Hydrolysat aus Chitin hemmte die Bindung. Keine BindungSStellen für das Weizenkeimlektin konnten auf dem subsromatären Vesikel und auf der Infektionshyphe nachgewiesen werden.
Das Lektin von Canavalia ensiformis wurde nicht, die Lektine von Griffonia simplicifolia und Lotus tetragonolobus wurden nur schwach von den Infektionsstrukturen gebunden. Die Lektine von Pbaseolus vulgaris und Aracbis bypogaea banden schwach an das substOmatäre Vesikel und an die Infektionshyphe. Das Lektin von Ricinus communis haftete nur an die Infektionshyphe. Offensichtlich besitzt der Keimschlauch von U. fabae neben Chitin noch andere Oberflächenkohlenhydrate: z. B. GalaktOse und Fucose. Die Bedeutung der Oberflächenkohlenhydrate für die Winsspezifität wird diskutiert.
