Patent number: 6670189Abstract: Methods for identifying organisms capable of degrading fumonisin. Fumonisin can be incorporated into culture medium for selection of organisms resistant to fumonisin and/or capable of growing on fumonisin as a sole carbon source. Using this method, several organisms have been identified. These organisms can be used to isolate the enzymes and the genes responsible for conferring fumonisin-resistance. The gene can be cloned and inserted into a suitable expression vector so that the protein can be further characterized. Additionally, the DNA encoding for fumonisin degrading enzymes can be used to transform plant cells normally susceptible to Fusarium or other toxin-producing fungus infection. Plants can be regenerated from the transformed plant cells. In this way, a transgenic plant can be produced with the capability of degrading fumonisin, as well as with the capability of producing the degrading enzymes.Type: GrantFiled: December 5, 2000Date of Patent: December 30, 2003Assignee: Pioneer Hi-Bred International, Inc.Inventors: Jonathan Duvick, Joyce R. Maddox, Tracy A. Rood, Xun Wang, Benjamin A. Bowen, Jacob T. Gilliam
