This invention provides methods for producing plants with increased seed and biomass production. More specifically, this invention provides methods for producing plants which have increased yields for a number of plant traits, including seed number, seed weight, the number of seed heads, flag leaf weight and total plant weight. This invention also provides methods for improving the Harvest Index of a plant. In a preferred embodiment, the methods comprise introducing into a plant a nucleic acid wherein the nucleic acid is selected from the group consisting of a nucleic acid comprising SEQ ID NO: 3, a nucleic acid which hybridizes with SEQ ID NO: 3 under high stringency conditions and encodes a polypeptide that retains biological activity of SH2-REV6-HS, a fragment of SEQ ID NO: 3 encoding a peptide that retains biological activity of SH2-REV6-HS, a nucleic acid encoding a polypeptide comprising SEQ ID NO: 4, or a fragment thereof that retains biological activity of SH2-REV6-HS, and a nucleic acid encoding an SH2HS or an SH2RTS polypeptide. The present invention also concerns plants obtained by the methods provided herein.
