  • Patent number: 6846969
    Abstract: The invention is drawn to plant cell transformation with a nucleic acid construct comprising a prokaryotic ammonium-specific asparagine synthetase, type A, coding sequence, operably linked to a chloroplast transit peptide-encoding sequence, wherein said plant cells also contain a nucleic acid construct comprising a chloroplastic glutamine synthetase coding sequence in antisense orientation. Plant cells containing both nucleic acid constructs, and plants regenerated therefrom, exhibit improved growth characteristics.

  • Publication number: 20030204873
    Abstract: The invention relates to a method for producing transgenic plants by means of modified 5-aminolevulinic acid biosynthesis, transgenic plant cells, transgenic plant parts, transgenic seeds, and transgenic reproduction material. The invention is characterised in that one or several nucleic acid molecules coding for a protein with a 5-aminolevulinic acid synthase function (ALAS), selected from a group of feedback regulated ALAS, animal ALAS and bacterial ALAS, an active fragment thereof or an antisense or complementary sequence thereof, are integrated into the plant genome in a stable form. Effectors of natural 5-aminolevulinic acid biosynthesis in plants are found using a method for determining effector efficacy of a test substance in relation to a GSAAT, by: a) determining the enzymatic activity of the GSAAT in the absence of a test substance b) determining the enzymatic activity of the GSAAT in the presence of a test substance; and c) by comparing the enzymatic activities determined under a) and b).

  • Patent number: 6603062
    Abstract: Provided is a method for producing transgenic monocotyledonous plants, plant cells, plant parts, seeds, and reproduction material with modified 5-aminolevulinic acid biosynthesis. This is achieved by stably integrating one or several nucleic acid molecules coding for a protein with a 5-aminolevulinic acid synthase function (ALAS) isolated from the alpha group of purple bacteria, an active fragment thereof or an antisense or complementary sequence thereof, into tie plant genome in stable form. This method can also be used to control undesired vegetation Also provided is a method for producing transgenic plants or plant cells whose glutamate-1-semialdehyde transferase (GSAAT) expression is suppressed or inhibited by stable integration of at least one nucleic acid molecule encoding an ALAS isolated from the alpha group of purple bacteria into the plant plastome by plastid transformation.

  • Patent number: 6284945
    Abstract: Protoplasts which regenerate reproducibly in a short time to normal, fertile plants can be regenerated from an auxin-autotrophic genotype of Zea mays (L.). Starting from immature embryos on hormone-free media, an auxin-autotrophic, embryogenic callus is formed on the shoot basis of the seedlings, which callus retains its embryogenic potential over a substantial period of time when subcultured on hormone-free medium. In addition to fully-developed embryos, adventitious embryos are also formed under suitable culture conditions (6-9% of sucrose in the medium). When the sucrose content is reduced to 2-3% and 2,4-dichlorophenoxyacetic acid is added, soft, granular calli are formed which consist of embryogenic cell aggregates (type II callus). After subculturing the type II callus in the form of a cell suspension culture, totipotent protoplasts can be isolated. From these protoplasts, the maize plants according to the invention are regenerated.

  • Patent number: 5908810
    Abstract: This invention concerns a method for improving the yield of crop plants which are resistant to glutamine synthetase inhibitors by treating the plants with glutamine synthetase inhibitors at application rates which are not harmful to the plants. In particular, the invention relates to a method in which glutamine synthetase inhibitors are employed to increase the yield of plants which are protected against the herbicidal activity of the glutamine synthetase inhibitors by expression of an n-acetyltransferase gene.

  • Patent number: 5808174

  • Patent number: 5792926
    Abstract: Virus genes, such as coat protein genes, which confer viral resistance or bring about a reduction in the signs of infection by the corresponding virus can be combined with herbicide-resistance genes, such as the phosphinothricin resistance gene, for the transformation of plants. A combination of a viral gene and a herbicide-resistance gene facilitates the selection of transgenic plants. In addition, in practical field cultivation, the vitality of the plants is increased by the virus tolerance, and an improved plant protection is possible due to the herbicide resistance gene.
