Patent ID: 8217223

Claim:
A method of producing a transgenic plant having an increase in seed weight comprising, transforming a plant cell with an expression vector comprising a lipid metabolism protein (LMP) nucleic acid and generating from the plant cell the transgenic plant, wherein the nucleic acid encodes a polypeptide that increases seed weight in the plant, and wherein the nucleic acid comprises a polynucleotide sequence selected from the group consisting of: a) the polynucleotide sequence of SEQ ID NO: 40 or SEQ ID NO: 41; b) a polynucleotide sequence encoding the polypeptide of SEQ ID NO: 42; c) a polynucleotide sequence having at least 90% sequence identity with the full-length LMP nucleic acid of a) or b) above; d) a polynucleotide sequence that encodes a polypeptide having at least 90% sequence identity with the amino acid sequence of SEQ ID NO: 42; e) a polynucleotide sequence that is complementary to the full-length LMP nucleic acid of a) or b) above; and f) a polynucleotide sequence that hybridizes under stringent conditions to the full-length LMP nucleic acid of a) or b) above, wherein the stringent conditions comprise hybridization in 6×SSC at about 45° C. followed by one or more washes in 0.2×SSC, 0.1% SDS at 50 to 65° C., wherein the seed weight is increased in the transgenic plant as compared to an untransformed wild type variety of the plant.
