Abstract:
The invention relates to a method for preventing and/or suppressing growth of transgenic plants comprising a transgenic expression cassette for a D-amino acid oxidase, which are grown on a field, in subsequent seasons among a population of other plants on said field or neighboring fields based on selective killing of the transgenic plants by application of a D-amino acid (e.g. D-isoleucine) which is metabolized by said D-amino acid in said transgenic plants into a phytotoxic compound.
Abstract:
The invention relates to improved methods for the biosynthesis of vitamin E. Said methods are characterized by the inhibition of the catabolization of homogentisate to maleylacetoacetate and fumarylacetoacetate and then to fumarate and acetoacetate. The invention also relates to the combination of this inhibition with methods that increase the provision of homogentisate or that promote the conversion of homogentisate to vitamin E. The invention further relates to nucleic acid constructs and vectors, which can be used to implement the inventive methods, in addition to transgenic plant organisms produced from said constructs and vectors.
Abstract:
The invention relates to a new type of expression cassettes which, under genetic control, contain regulating nucleic acid sequences a) nucleic acid sequence coding for 4-hydrophenylpyruvate dioxygenase (HPPD) or for one of its functional equivalents; and/or b) at least one nucleic acid sequence (anti-HGD), which can inhibit the homogentisate-dioxygenase (HGD) activity. The invention also relates to vectors which are suitable for the production of plants having an increased tocopherol content, to transgenic plants produced therewith, and to a method for the production of transgenic plants having an increased tocopherol content.
Abstract:
The invention relates to improved construct and methods for eliminating maker sequences from the genome of plants, based on dual-function selection marker which - depending on the employed compound - can act as both negative and counter-selection marker.
Abstract:
A method for preparing a nonhuman organism with faster growth and/or increased yield in comparison with a reference organism, which method comprises increasing the activity of L450 in said organism or in one or parts thereof in comparison with a reference organism.
Abstract:
Method for the production of plants with enhanced vitamin E biosynthesis efficiency by overproduction of a 1-deoxy-D-xylulose-5-phosphate synthase gene from Arabidopsis or E. coli.
