Antifungal polypeptide and process for its production

摘要

The polypeptide with the sequence (SEQ ID NO:1) Ala-Thr-Tyr-Asn-Gly-Lys-Cys-Tyr-Lys-Lys-Asp-Asn-Ile-Cys-Lys-Tyr-Lys-Ala-Gln-Ser-Gly-Lys-Thr-Ala-Ile-Cys-Lys-Cys-Tyr-Val-Lys-Lys-Cys-Pro-Arg-Asp-Gly-Ala-Lys-Cys-Glu-Phe-Asp-Ser-Tyr-Lys-Gly-Lys-Cys-Tyr-Cys can be produced by the fermentation of Aspergillus giganteus and used as an antifungal agent. Expression of this polypeptide gene in plants strongly inhibits the growth of phytopathogenic fungi on the plant.
