Patent ID: 8878006

Claim:
A method for enhancing seed yield in a plant relative to a control plant, comprising: (a) introducing and expressing in a plant, plant part, or plant cell a nucleic acid encoding a 2-cysteine peroxiredoxin (2-Cys PRX) polypeptide, wherein said nucleic acid is operably linked to a root-specific promoter; and (b) selecting a plant having increased seed yield relative to a control plant on the basis of said plant showing increased seed yield relative to said control plant, wherein said 2-Cys PRX polypeptide comprises from N-terminus to C-terminus: (1) a plastidic transit peptide; and (2) a 2-Cys PRX domain, and has at least 95% sequence identity to the amino acid sequence of SEQ ID NO: 2, and wherein said 2-Cys PRX polypeptide further comprises a motif comprising the amino acid sequence of SEQ ID NO: 77 and a motif comprising the amino acid sequence of SEQ ID NO: 78.
