Abstract

The subject invention pertains to a novel variant of the maize gene, Shrunken2 (Sh2) and a method of using that gene. The variant gene, Sh2-m1Rev6, encodes a subunit of the ADP-glucose pyrophosphorylase (AGP) enzyme that has additional amino acids inserted near or in the allosteric binding site of the protein. Corn seed expressing the Sh2-m1Rev6 gene has a 15% weight increase over wild type seed. The increase in seed weight is not associated simply with an increase in percentage starch content of the seed.
