Open the CIPO recordAbstract From the Canadian patent
Promoters isolated from genomic DNA of strawberry plants are disclosed. The promoters are capable of tissue-specific expression in transgenic plants. A plant promoter that is a nucleic acid region located upstream of the 5' end of a plant DNA structural coding sequence that is transcribed at high levels in ripening fruit. This promoter region is capable of conferring high levels of transcription in ripening fruit tissue and in developing seed tissues when used as a promoter for a heterologous coding sequence in a chimeric gene. The promoter and any chimeric gene in which it may be used can be used to obtain transformed plants or plant cells. Chimeric genes including the isolated …

Why it's free to use
- Filed February 4, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 4, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 4, 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.
