Abstract: | A cytochemical method for light microscopical studies is described which allows the specific detection of fungal hyphae in plant-fungus associations: e.g. lichens, mycorrhiza, or fungal infections of plant tissue. The specimens were fixed and embedded in epoxy resin by a standard protocol for electron microscopy. Semithin sections were successively incubated with fluorescein isothiocyanate labelled wheat germ agglutinin (FITC-WGA) and calcofluor white (CW). FITC-WGA stained exclusively the fungal cell walls while CW stained both the fungal and the plant cell walls. Therefore, FITC-WGA is an excellent marker for the fungal hyphae. |
