Detection of abiotic stress – Summary
This chapter introduces two patent families, both filed by Syngenta Participations AG, that used microarray technology to identify polynucleotide sequences that have altered expression in a plant that has been exposed to cold, saline, or osmotic stress (or combinations of the stresses). There are several differences between the two patent families:
| Patent family | Assignee | Subject plant * | Claim structure |
|---|---|---|---|
| WO 2002/016655 | The Scripps Research Institute Syngenta Participations AG |
Rice |
|
| WO 2003/008540 | Syngenta Participations AG | Arabidopsis thaliana |
|
* The plants in this column were used to identify polynucleotides and polypeptides of interest, however the claims in the patent documents are not limited to them.
Both patent families contain claims that are generally drawn towards use of the stress-responsive regulatory elements (nucleotide sequence that affects transcription of the corresponding coding region) to create sentinel plants that can detect presence of stress
