An Elicitor Isolated From Sporisoriun scitamineum Multiplies Xylem Bridges between Vascular Neighboring Bundles in Sugar

A chemical simulation of the infection of sugar cane leaves by smut (Sporisorium scitamineum), using an elicitor isolated from the growing fungal mycelium, provokes an increase of the pattern of lignification of both sclereids and xylem elements. The entry of the elicitor into the tissues of the plant likewise induces the production and secretion of a mucilaginous material, probably glycoproteins, that has been considered as a primary response of defense.
