Antiviral activity of glucosylceramides isolated from Fusarium oxysporum against Tobacco mosaic virus infection.

Natural elicitors derived from pathogenic microorganisms represent an ecologic strategy to achieve resistance in plants against diseases. Glucosylceramides (GlcCer) are classified as neutral glycosphingolipids. GlcCer were isolated and purified from Fusarium oxysporum mycelium.
