1. An elite maize plant stably transformed with a recombinant polynucleotide sequence encoding a polypeptide comprising an amino sequence that is at least 94% identical to SEQ ID NO: 1 and comprising the MADS box domain that corresponds to the first 61 amino acids of SEQ ID NO: 1, wherein the recombinant polynucleotide is operably linked to a maize GOS2 constitutive promoter, and wherein the elite maize plant exhibits increased grain yield of at least two bushels/acre in a field compared to a control maize plant not containing the recombinant polynucleotide when grown at a population density of at least 36,000 plants per acre.
