    • Function

    • Antimicrobial peptide active against fungi, Gram-positive and Gram-negative bacteria. Has no effect on spore germination. Destroys spores in germinated conidia by disruption of cell walls and membranes in A. niger and B. sorokiniana. Causes vacuolization of germinated macro- and microconidia in F. oxysporum, F. graminearum and F. culmorum. Strongly inhibits growth of P. infestans on potato tubers above concentrations of 13.6 µg/ml.
