Abstract

Isolated nucleic acid molecules are provided that encode maize UDPGdH variant UDPGdH, and mutant UDPGdH proteins. These nucleic acid molecules can be used to produce transgenic plants having altered quality or quantity of starch. Also provided are vectors capable of expressing such nucleic acid molecules, host cells containing, such vectors, and polypeptides encoded by such nucleic acids.
