Open the CIPO recordAbstract From the Canadian patent
A method for regulating cell death in a plant includes the steps of: transforming a plant cell with a polynucleotide containing a gene encoding DS9 or a homologue thereof or a part of the gene; and redifferentiating the transgenic plant cell to obtain a plant. The DS9 or the homologue thereof is an ATP-dependent Zn-type metalloprotease. The polynucleotide decreases or increases production of the ATP-dependent Zn-type metalloprotease in the plant cell, whereby cell death of a cell in the plant is promoted or suppressed.

Why it's free to use
- Filed November 12, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 12, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 12, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
