Patent ID: 8030540

Claim:
A transgenic corn seed comprising an expression construct that comprises a plant codon-optimized nucleic acid sequence that expresses an enzymatically active GlgC3 protein in endosperm plastids of said seed, wherein, when compared to an isogenic corn seed which does not express the GlgC3 protein in endosperm plastids, said transgenic corn seed is characterized by: a) an increase of at least 5% in oil content over the oil content of said isogenic corn seed; b) increases of at least about 5% in one or more of amino acids aspartic acid, glycine, isoleucine, histidine, lysine, arginine, valine, methionine, threonine, cysteine, and tryptophan over the amounts of said amino acids in said isogenic corn seed; and c) a starch content which is decreased or not changed when compared to said isogenic corn seed.
