ABSTRACT
At present, over two hundred plant lectins have been isolated and characterized in some detail with respect to their molecular structure, biochemical properties and carbohydrate-binding specificity. Although in the past most interest in plant lectins has been focused on lectins in dry seeds, especially from leguminous species, evidence has been accumulating that lectins also occur in vegetative tissues and are widespread in a large number of plant families belonging to all major taxonomical groupings (Etzler, 1986).
