Patent ID: 8853492

Claim:
A method for increasing plant yield comprising: (a) introducing and expressing in a plant, plant cell or plant part a nucleic acid encoding a class I homeodomain leucine zipper (HDZip) hox5 polypeptide; and (b) selecting for a plant having increased yield relative to a corresponding control plant, wherein said nucleic acid is: a nucleic acid comprising the nucleotide sequence of SEQ ID NO: 1; (ii) a nucleic acid encoding a polypeptide comprising the amino acid sequence of SEQ ID NO: 2; (iii) a nucleic acid encoding a polypeptide having at least 90% sequence identity to the amino acid sequence of SEQ ID NO; 2; or (iv) a nucleic acid that hybridizes to the nucleic acid of (i) or (ii) under stringent hybridization conditions comprising hybridization in 1×SSC at 70° C., or 1×SSC and 50% formamide at 50° C., followed by washing in 0.3×SSC at 70° C.
