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.
A method for producing a transgenic monocotyledonous plant, its cells, its parts, its seeds, and its propagation material, comprising the step of introducing into a monocotyledonous plant one or more nucleic acid molecules encoding a 5-aminolevulinic acid synthase (ALAS) isolated from the alpha group of purple bacteria, whereby the one or more nucleic acid molecules are stably integrated into the plant genome.
A method for expressing an ALAS in transgenic monocotyledonous plant cells or plants, comprising the step of introducing into the plant cells or plants at least one nucleic acid molecule encoding an ALAS isolated from the alpha group of purple bacteria. whereby the nucleic acid molecule is expressed in the plant cells or plants.
A method for producing transgenic plant cells or plants whose glutamate-1-semialdehyde transferase (GSAAT) expression is suppressed or inhibited, and wherein the plant is a monocotyledonous plant, comprising the step of introducing at least one nucleic acid molecule encoding an ALAS isolated from the alpha group of purple bacteria into the plant plastome by plastid transformation, whereby the nucleic acid molecule is stably integrated into the plant plastorne.
A non-naturally occurring chimeric gene, containing at least a promoter for driving expression in plants, functionally linked to a DNA molecule encoding an ALAS isolated from the alpha group of purple bacteria.
A transgenic monocotyledonous plant, its cells, its parts, its seed or its propagation material, each containing a DNA molecule encoding a protein with the function of an ALAS isolated from the alpha group of purple bacteria.
