Disclosed are isolated .beta.-amyrin synthase-encoding cDNA and gDNA nucleic acids. The genes are involved in saponin synthesis. One preferred embodiment is the nucleotide sequence which encodes the polypeptide of Annex II. Also provided are variant sequences (e.g. alleles derivatives) and complementary , sequences plus vectors, host cells, plants, polypeptides and associated , processes of production and methods of use e.g. for influencing or affecting triterpene synsthesis, and hence the resistance to a fungal pathogen taste, palatability or nutritional value of the plant. Also provided is the .beta.amyrin synthase promoter sequence and variants and uses thereof.

Why it's free to use
- Filed December 20, 2000 and granted May 10, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 20, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 20, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
