Patent ID: 8269064

Claim:
A genetically modified plant cell comprising an enzymatic activity of a mutansucrase protein in their plastids and wherein said genetically modified plant cell synthesizes a modified starch in comparison to starch synthesized by corresponding non-genetically modified wild-type plant cells, wherein said plant cell comprises a nucleic acid molecule encoding a mutansucrase protein comprising: a) a nucleic acid molecule encoding the protein of SEQ ID NO: 2 or parts thereof; b) a nucleic acid molecule encoding a protein having at least 95% sequence identity to SEQ ID NO: 2 or parts thereof; c) a nucleic acid molecule comprising the nucleotide sequence of SEQ NO: 1, or parts thereof; d) a nucleic acid molecule having at least 95% identity to nucleic acids 439-3153 of SEQ ID NO: 1; or e) a nucleic acid molecule that deviates from the nucleic acid molecules of a), b), c), or d) due to the degeneration of the genetic code; wherein said nucleic acid molecules or parts thereof encode a mutansucrase protein capable of catalyzing the synthesis of mutan from sucrose; and wherein the nucleic acid molecule or parts thereof encoding a mutansucrase protein is stably integrated into the genome of the plant cell.
