Abstract:
A transgenic plant cell that expresses an RNA molecule transcribed from a DNA sequence, or a biologically active fragment of said DNA sequence, wherein said fragment is sufficient to modify starch metabolism when expressed in antisense orientation, which DNA sequence or fragment thereof is in antisense orientation with respect to an operably linked plant promoter, and which DNA sequence is selected from the group consisting of:(1) a DNA sequence comprising: (a) a nucleotide sequence encoding a protein having the amino acid sequence of SEQ ID NO: 8; (b) the coding region of SEQ ID NO: 7; or (c) a nucleotide sequence that is more than 90% homologous to the nucleotide sequence of (a) or (b); (2) a DNA sequence comprising: (d) a nucleotide sequence encoding a protein having the amino acid sequence of SEQ ID NO: 10; (e) the coding regon of SEQ ID NO:9; or (f) a nucleotide sequence that is more than 90% homologous to the nucleotide sequence of (d) or (e), excluding DNA molecules encoding a starch synthase from rice; and (3) a DNA sequence comprising: (e) a nucleotide sequence encoding a protein having the amino acid sequence of SEQ ID NO: 12; (f) the coding region of SEQ ID NO: 11; or (g) a nucleotide sequence that is more than 90% homologous to the nucleotide sequence of (e) or (f).
