The present invention relates to isolated nucleotide sequences useful for the production of plants with a modified embryo sac, embryo and or endosperm development, and to transgenic cells and plants transformed with the nucleotide sequences.

Embryo sac-specific genes

The present invention relates to nucleic acid molecules encoding enzymes which are involved in the starch synthesis in plants. These enzymes are starch synthases from wheat. The invention further relates to vectors and host cells containing said nucleic acid molecules, in particular transformed plant cells and plants regenerated from these cells, which exhibit an increased or a reduced activity of the described starch synthases.

Nucleic acid molecules encoding enzymes from wheat which are involved in starch synthesis

The present invention relates to monocotyledon plant cells and plants which are genetically modified, wherein the genetic modification consists of the introduction of an extraneous nucleic acid molecule which codes for a protein with the biological activity of an R1 protein. The present invention further relates to means and methods for the production thereof. Plant cells and plants of this type synthesise a modified starch, which is characterised in that it has an increased phosphate content and/or a modified phosphorylation pattern and/or an increased final viscosity in an RVA profile and/or a reduced peak temperature in DSC analysis and/or an increased gel strength in the texture analysis compared with starch from corresponding non-genetically modified monocotyledon plants. Therefore, the present invention also relates to the starch which is synthesised from the plant cells and plants according to the invention, and to methods of producing said starch. The present invention further relates to wheat flours which contain said modified starches, and to food products and bakery products which contain said wheat flours and/or starch.

Monocotyledon plant cells and plants which synthesize modified starch

The present invention relates to transgenic plants, such as wheat or maize, comprising plant cells having SEQ. ID. NO. 1 and seeds derived from those plants. It also relates to the use of said seed for the preparation of a flour which in turn is used for the preparation of food and/or feed such as dough, batters, pastries, cookies, pasta, wafers, bread and/or confectionery. The thus obtained gliadin-free foodstuff is beneficial for feeding patients suffering from coeliac disease and/or other forms of gluten intolerance.

Modified low molecular weight glutenin gene in plants

The present invention relates to monocotyledon plant cells and plants which are genetically modified, wherein the genetic modification consists of the introduction of an extraneous nucleic acid molecule which codes for a protein with the biological activity of an R1 protein. The present invention further relates to means and methods for the production thereof. Plant cells and plants of this type synthesise a modified starch, which is characterised in that it has an increased phosphate content and/or a modified phoshorylation pattern and/or an increased final viscosity in an RVA profile and/or a reduced peak temperature in DSC analysis and/or an increased gel strength in the texture analysis compared with starch from corresponding non-genetically modified monocotyledon plants. Therefore, the present invention also relates to the starch which is synthesised from the plant cells and plants according to the invention, and to methods of producing said starch. The present invention further relates to wheat flours which contain said modified starches, and to food products and bakery products which contain said wheat flours and/or starch.

Monocotyledon plant cells and plants which synthesise modified starch

Nucleic acid molecules encoding an R1-protein from wheat are provided. Also provided are transgenic plant cells and plants containing the nucleic acid molecules, and starch obtainable from the transgenic plant cells and plants.

Nucleic acid molecules from wheat encoding an R1-protein, and transgenic plant cells and plants comprising the nucleic acid molecules

The present invention relates to isolated nucleotide sequences useful for the production of plants with a modified embryo sac, embryo and/or endosperm development, and to transgenic cells and plants transformed with the nucleotide sequences.
