Open the CIPO recordAbstract From the Canadian patent
The present invention provides a gene, termed "FT" for flowering locus T and , a polypeptide encoded by FT that modulates flower development in plants. FT is useful in methods of the invention for producing genetically modified plants characterized as having the phenotypic trait of modulated flower development for example early or delayed flowering. Such plants can be genetically modified by nucleic acids encoding functional FT peptides; at least one antisense nucleic acid for FT; a structural gene that encodes wild-type FT polypeptide; or a structural gene that encodes dominant negative polypeptides for example, in order to modulate flowering in the plant.

Why it's free to use
- Filed April 13, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 13, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 13, 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.
