Isolation of biocidal peptides from Anethum graveolens seeds

摘要

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 mu g/mL. Peptide D-AFP-3 was the most active biocidal peptide.
