Analysis of the isolectin composition of 102 individual nettle ( Urtica dioica L.) clones by ion‐exchange chromatography revealed the occurrence of at least 11 different isolectins, which all had the same molecular structure and exhibited identical carbohydrate‐binding specificity and agglutination properties. All 11 isolectins, however, did not occur simultaneously; 34 combinations of either 1, 2, 3, 4 or 5 isolectins were found. Since the occurrence of multiple molecular forms of the nettle agglutinin cannot be explained by the (partial) autotetraploid character of stinging nettle it is postulated to rely on the expression of a family of closely related lectin genes.
