摘要:
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.
摘要:
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.

摘要:
The present invention relates to optimized ketolase coding sequences, corresponding coding sequences and genetic constructs alone or in combination with beta-cyclase coding sequences, their use for the expression in plants, in particular in plants of the genus Tagetes, to such genetically modified plants, to a process for the preparation of carotenoid products by culturing the genetically modified plants. The present invention further relates to the expression of optimized ketolase coding sequences alone or in combination with beta-cyclase coding sequences under control of an Antirrhinum majus ANTHIRRHINUM FIDDLEHEAD (AFI) promoter, In addition the invention relates to the use of an AFI promoter for heterologous gene expression, preferably for flower-specific expression of genes in plants of the genus Tagetes, to the genetically modified plants of the genus Tagetes, and to a process for producing biosynthetic products by cultivating the genetically modified plants.
