The present invention relates to 
monocotyledon plant ells 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 is 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.
