Abstract Pea lectin (PSL) is a secretory sugar-binding protein, readily soluble in aqueous solutions of low osmolarity. However, PSL also appears to be associated with the plasma membrane at the tip of young pea root hairs. By using the Wilhelmy plate method, we found that PSL can insert into a lipid monolayer. This property appeared to be independent of the sugar-binding ability of the protein. This result suggests that PSL may be directly involved in membrane-mediated interactions with saccharide ligands, for example during root hair infection by symbiotic rhizobia.
