Patent number: 7223909Abstract: The formation of a carotenoid compound containing a 4-keto-?-ionene ring such as astaxanthin or canthaxanthin in flowers, and particularly in the corolla and reproductive parts of a flower of a higher plant whose flowers produce a carotenoid compound containing a ?-ionene ring such as ?-carotene or zeaxanthin, but otherwise do not produce astaxanthin or canthaxanthin is disclosed. One or more genes controlled by a promoter are inserted (transformed) into a higher plant. The inserted gene encodes a chimeric enzyme including (a) a carotenoid-forming enzyme that is at least a ketolase. That gene is operatively linked to (b) a plastid-directed transit peptide. Some higher plants to be transformed produce at least zeaxanthin or ?-carotene in their flowers prior to transformation, whereas other plants produce little if any colored carotenoid pigments prior to transformation and are transformed with a cassette of carotenoids-forming genes. Methods of transformation and use of the transformed plants are described.Type: GrantFiled: March 20, 2003Date of Patent: May 29, 2007Assignee: Ball HorticulturalInventors: Randal Hauptmann, Robert Eisenreich, William Eschenfeldt, Zubin Khambatta

Patent number: 5955646Abstract: Chimeric regulatory regions and gene cassettes based upon Agrobacterium tumefaciens opine sythase genes are provided for expressing foreign genes in plants. Various upstream activating sequences from opine synthase genes like the mannopine synthase and the octopine synthase genes are operably linked with promoters (or promoters plus activating sequences), both of which are then operably linked to the foreign gene. These regions and cassettes permit expression levels and patterns that could not be obtained previously.Type: GrantFiled: July 31, 1996Date of Patent: September 21, 1999Assignees: Biotechnology Research And Development Corporation, Purdue Research FoundationInventors: Stanton B.

Patent number: 5618988Abstract: A transgenic higher plant, seed containing the transgene, and methods of providing enhanced carotenoid accumulation are disclosed. The transgenic higher plant has a genomic structural gene that encodes a chimeric polypeptide conjugate and over accumulates a colored native carotenoid in a preselected storage organ relative to the accumulation in a non-transgenic plant of the same type. Expression of the chimeric polypeptide is driven by a promoter operatively linked to that structural gene that provides storage organ-enhanced expression. The chimeric polypeptide has an N-terminal plastid transit peptide portion whose C-terminus is linked to the N-terminus of a non-higher plant phytoene synthase enzyme.Type: GrantFiled: October 28, 1994Date of Patent: April 8, 1997Assignee: Amoco CorporationInventors: Randal Hauptmann, William H. Eschenfeldt, Jami English, Friedhelm L. Brinkhaus
