Publication number: 20050229269Abstract: A recombinant plant genome contains a gene cascade such that it is incapable of producing a mature plant but requires the presence of a chemical inducer. The gene cascade includes a gene switch which is inducible by external application of a chemical inducer and which controls expression of a gene product which affects expression of a second gene in the genome. Survival or development of the plant is dependant upon either expression or non-expression of the second gene and application of the inducer, therefore, selects whether or not the plant develops. In one example the second gene encodes a cytotoxic molecule and expression of that gene is fatal to the plant. In another example the second gene encodes a desirable characteristic which may be excised selectively by applying or withholding chemical application. The second gene may be placed under control of a development regulated promoter.Type: ApplicationFiled: January 21, 2005Publication date: October 13, 2005Inventors: Simon Jonathan Bright, Andrew Greenland, Ian Jepson, Jacqueline Paine

Patent number: 6700039Abstract: This invention relates to a method of controlling sprout formation in plants and parts thereof including vegetative storage organs. The method involves the use of target and organ specific promoters to control expression of DNA sequences to inhibit sprouting. Sprouting is restored by switching on expression of DNA sequences using inducible promoter regions where sprouting may be controlled by, for example, application of an external chemical stimulus.Type: GrantFiled: January 21, 2000Date of Patent: March 2, 2004Assignee: Syngenta LimitedInventors: Ian Jepson, Marcus Ebneth, Uwe Sonnewald

Patent number: 6683230Abstract: Methods of preparing hybrid seed are described. One such method comprises interplanting a male parent plant which is male fertile and homozygous recessive female sterile and a female parent plant which is homozygous recessive male sterile and female fertile, allowing cross-pollination and obtaining the seed produced therefrom. The genomic material of each parent plant may also have integrated therein a gene construct comprising a promoter sequence-responsive to the presence or absence of an exogenous chemical inducer, optionally operably linked to one or more enhancer or intron sequences, operably linked to a gene which fully restores the fertility of each parent plant, the gene being expressed by the application to the plant of an external chemical inducer thereby allowing each parent to self-pollinate.Type: GrantFiled: September 18, 2000Date of Patent: January 27, 2004Assignee: Syngenta LimitedInventors: Ian Jepson, Allan Daly, Mary Elizabeth Knight, Michael William Bayliss
