Abstract
The invention alters the physical characteristics of starch granules in a plant. Methods are provided for reducing starch granule size by stably introducing into the genome of the plant or plant cell a DNA construct comprising a polynucleotide encoding a polypeptide operably linked to a promoter that drives expression in a plant and operably linked to a plastid transit peptide. Compositions of the invention include transgenic plants and seeds having a reduced starch granule size. Compositions also include starch isolated from these plants and seeds. The modified starch granules find use in a wide range of food, feed, and industrial applications.
