Abstract

Nucleic acid molecules are described which encode enzymes involved in the starch synthesis in plants. These enzymes are starch phosphorylases from maize. The invention further relates to vectors containing such nucleic acid molecules and to host cells transformed with the described nucleic acid molecules, in particular to transformed plant cells and to plants which may be regenerated therefrom and which exhibit an increased or reduced activity of the described proteins.
