Abstract

A specific lectin was isolated from cephalodiate thallus lobes of the lichen Peltigera aphthosa and purified to homogeneity by two steps: Chromatography on carboxymethyl-cellulose (CMC); and affinity chromatography on a lactose agarose column. TEM immunogold labeling using antibodies raised against the lectin, revealed a clear gold labeling of fungal cell walls adjacent to the cephalodial Nostoc cells. We suggest that the lectin located on the fungal cell wall recognizes the compatible Nostoc at the initiation of cephalodia formation.
