Comments
Mutant corn seed
Produces seed with a 15% weight increase over wild-type seed, but without a corresponding increase in starch
The Sh2-m1Rev6 variant encodes an ADP-glucose pyrophosphorylase enzyme subunit that has the arginine:threonine amino acid pair inserted between the tyrosine and isoleucine at amino acid residues 503 and 504, respectively, of the native protein.
Corn seed containing serine and tyrosine in a position of the large subunit of the endosperm enzyme, adenosine diphosphate glucose pyrophosphorylase encoded by the gene shrunken2
