Isolation of biocidal peptides from Anethum graveolens seeds

Three peptides with fungicidal activity with molecular weights 4–8 kDa were isolated from Anethum graveolens L. seeds. The cationic peptides were tested in vitro and inhibited the pathogenic strain Verticillium dahliae. The effective concentrations required for 50% inhibition (IC50) growth of fungi were in the range 1.3–31 µg/mL. Peptide D-AFP-3 was the most active biocidal peptide.
