Abstract

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.
