Patent ID: 8569575

Claim:
A method for enhancing a seed yield-related trait in a plant relative to a control plant, comprising (a) increasing expression in a plant of an isolated nucleic acid, and (b) selecting for a plant having an enhanced seed yield-related trait relative to a corresponding control plant, wherein the isolated nucleic acid comprises a nucleic acid sequence encoding a Circadian Clock Associated1 (CCA1)-like protein, which comprises a SANT domain having motif 1 of SEQ ID NO: 141 and motif 2 of SEQ ID NO: 142, where the nucleic acid sequence comprises i) the nucleic acid sequence of SEQ ID NO: 1; ii) a nucleic acid sequence encoding a polypeptide comprising the amino acid sequence of SEQ ID NO: 2; iii) a nucleic acid sequence encoding a polypeptide comprising an amino acid sequence having at least 90% sequence identity to SEQ ID NO: 2; or iv) a nucleic acid sequence capable of hybridizing with the nucleic acid sequence of SEQ ID NO: 1 under stringent hybridization conditions which comprise hybridization at 65° C. in 1×SSC or at 42° C. in 1×SSC and 50% formamide followed by washing at 50° C. in 2×SSC 65° C. in 0.3×SSC; and wherein said increased expression is effected by introducing and expressing in a plant, plant cell, or plant part said isolated nucleic acid, and wherein said seed yield-related trait comprises any one or more of the following: total seed yield, number of filled seeds, seed fill rate, number of flowers per panicle, harvest index, or thousand kernel weight.
