Antigenic differences in the surfaces of hyphae and rhizoids in allomyces.

Immunofluorescent techniques have demonstrated a difference in surface components of hyphae and rhizoids of Allomyces macrogynus. An antigenic component detected on the rhizoidal surface may be present, but masked, in the hyphal-wall matrix material. The system also allows visualization of the hyphal wall during aging, when changes from a smooth to a fissured surface are noted, and differences in adsorptive properties occur.
