Abstract
Summary: Wall‐bound acid phosphatases of an endomycorrhizal fungus of Erica hispidula L. were separated by PAGE, electrotransferred to nitrocellulose membranes and glycoprotein characteristics studied using Concanavalin A. An antiserum was raised against the major high‐molecular‐weight acid phosphatase and its specificity demonstrated by immunoblotting and ELISA. The antiserum reacted very little with protein extracts of other cellular fractions and was unable to bind to wall‐bound protein antigens of a mycorrhizal isolate from K. mauritanica. Ultrastructural localization of acid phosphatase by cytoenzymology and indirect immunogold labelling showed it to be almost exclusively associated with the fungal wall and septa of living hyphae, whilst in senescent hyphae it was also present within the disorganized cytoplasm.Keywords
