Abstract

Transgenic plant cells and plants are described which synthesise a starch which is modified in comparison with corresponding wild type plant cells and plants. The plant cells and plants described show a reduced activity of R1, BEI and BEII proteins. Furthermore, modified starches as well as methods for their production are described.
