Patent ID: 7141659

Claim:
A recombinant nucleic acid construct comprising: a) a promoter adapted to target expression of a payload polypeptide in a starch-containing tissue of a plant during starch formation, and b) a nucleic acid sequence which is oriented 3′ to said promoter encoding a hybrid polypeptide, said hybrid polypeptide comprising an N-terminal transit peptide having an amino acid sequence selected from the group consisting of SEQ ID NO: 33, SEQ ID NO: 34, SEQ ID NO: 35, SEQ ID NO: 35, SEQ ID NO: 36, and SEQ ID NO: 37; a starch-encapsulating region from maize starch synthase having an amino acid sequence 292–539 of SEQ ID NO: 21; and a payload polypeptide, wherein said payload polypeptide can be either N- or C-terminal to the starch encapsulating region.
