The present invention pertains to mutant alleles of the genes encoding the large subunit of ADP-glucose pyrophosphorylase in plants. When present in maize plants, these mutants alleles confer enhanced germination characteristics but without any diminishment of food quality or flavor as compared to plants that express the sh2-R genes. The subject invention also concerns methods for transforming plants with the mutant alleles. The subject invention also concerns plants that have the mutant alleles of the invention incorporated in their genome.

Why it's free to use
- Filed November 19, 1999 and granted April 17, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 19, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 19, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
