Patent ID: 7714186

Claim:
A genetically modified dicotyledonous plant cell comprising (1) a first foreign nucleic acid molecule, wherein said first foreign nucleic add molecule is (a) a DNA molecule encoding at least one antisense RNA that reduces the expression of at least one endogenous gene encoding a SSIII protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 1; (b) a DNA molecule which, via a co-suppression effect, reduces the expression of at least one endogenous gene encoding a SSIII protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 1; or (c) a DNA molecule that simultaneously encodes at least one antisense RNA and at least one sense RNA, where said antisense RNA and said sense RNA form a double-stranded RNA molecule that reduces the expression of at least one endogenous gene encoding a SSIII protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 1; (2) a second foreign nucleic acid molecule, wherein said second foreign nucleic acid molecule is (a) a DNA molecule encoding at least one antisense RNA that reduces the expression of at least one endogenous gene encoding a BEI protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 4; (b) a DNA molecule which, via a co-suppression effect, reduces the expression of at least one endogenous gene encoding a BEI protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 4; or (c) a DNA molecule that simultaneously encodes at least one antisense RNA and at least one sense RNA, where said antisense RNA and said sense RNA form a double-stranded RNA molecule that reduces the expression of at least one endogenous gene encoding a BEI protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 4; and (3) a third foreign nucleic acid molecule, wherein said third foreign nucleic acid molecule is (a) a DNA molecule encoding at least one antisense RNA that reduces the expression of at least one endogenous gene encoding a BEII protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 6; (b) a DNA molecule which, via a co-suppression effect, reduces the expression of at least one endogenous gene encoding a BEII protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 6; or (c) a DNA molecule that simultaneously encodes at least one antisense RNA and at least one sense RNA, where said antisense RNA and said sense RNA form a double-stranded RNA molecule that reduces the expression of at least one endogenous gene encoding a BEII protein, said DNA molecule comprising at least 95% identity with SEQ ID NO: 6; and wherein said plant cell synthesizes a modified starch having an amylose content of at least 30%, an increased phosphate content in comparison with starch from a corresponding wild-type plant cell, and an increased end viscosity in comparison with starch from a corresponding wild-type plant cell.
