Abstract: The invention relates to methods for the targeted transgenic expression of nucleic acid sequences in tissues of plants, and to transgenic expression cassettes and expression vectors comprising promoters with expression specificity for floral tissues. The invention further relates to organisms (preferably plants) transformed with these transgenic expression cassettes or expression vectors, to cultures, parts or propagation material derived from these organisms, and to their use for the production of foodstuffs, feedstuffs, seed, pharmaceuticals or fine chemicals.

Abstract: The invention relates to methods for the targeted transgenic expression of nucleic acid sequences in nonreproductive floral tissues of plants, and to transgenic expression cassettes and expression vectors which comprise promoters having an expression specificity for nonreproductive tissues of the flower. The invention further relates to organisms (preferably plants) transformed with these transgenic expression cassettes or expression vectors, to cultures, parts or propagation material derived therefrom, and to the use of the same for producing human and animal foods, seeds, pharmaceuticals or fine chemicals.

Abstract: The present invention relates to a process for preparing ketocarotenoids by cultivation of genetically modified organisms which, compared with the wild type, have a modified ketolase activity, to the genetically modified organisms, and to the use thereof as human and animal foods and for producing ketocarotenoid extracts.

Abstract: The present invention relates to the use of astaxanthin-containing plants or parts of plants of the genus Tagetes or astaxanthin-containing extracts of astaxanthin-containing plants or parts of plants of the genus Tagetes for oral administration to animals, methods for producing animal feed preparations, the animal feed preparations themselves, a method for pigmenting animals or animal products, and also a method for producing pigmented animals and animal products.

Abstract: The present invention relates to a process for preparing ketocarotenoids by cultivating genetically modified, non-human organisms which have, by comparison with the wild type, a modified ketolase activity, to the genetically modified organisms, to the use thereof as human and animal foods and for preparing ketocarotenoid extracts, and to novel ketolases and nucleic acids encoding these ketolases.

Abstract: The invention relates to a method for the production of ketocarotenoids by culturing genetically modified plants which show a ketolase activity in fruits.

Abstract: The present invention relates to a process for preparing zeaxanthin and/or biosynthetic intermediates and/or secondary products thereof by culturing genetically modified plants which, compared to the wild type, have a reduced ?-cyclase activity caused by double-stranded ?-cyclase ribonucleic acid sequences, to the genetically modified plants and to the use thereof as foodstuffs and feedstuffs and for producing carotenoid extracts.

Abstract: The present invention relates to a process for the preparation of ketocarotenoids by culturing genetically modified organisms which in comparison with the wild-type have a modified ketolase activity and a modified ?-cyclase activity, to the genetically modified organisms, and to their use as foodstuffs and feedstuffs for the production of ketocarotenoid extracts.

Abstract: The invention relates to methods for the specific, transgenic expression of nucleic acid sequences in non-reproductive flower tissues of plants, and expression cassettes and expression vectors containing promoters which have an expression specificity for non-productive tissues of the flower. The invention also relates to organisms (preferably plants), cultures, parts, or reproduction material derived therefrom, which are transformed by means of said transgenic expression cassettes or expression vectors, and the use thereof for producing food, fodder, seeds, pharmaceuticals, or fine chemicals.

Abstract: The present invention relates to a process for preparing ketocarotenoids by cultivation of genetically modified organisms which, compared with the wild type, have a modified ketolase activity, to the genetically modified organisms, and to the use thereof as human and animal foods and for producing ketocarotenoid extracts.
