Technology overview

The patent family described in this section filed by the Scripps Research Institute, Syngenta Participations AG, and Koninklijke Philips Electronics N.V. discloses a DNA microarray-based detection method of plants that have been exposed to abiotic stress.  The technology describes a group of nucleotide sequences that have altered expression patterns when rice is exposed to abiotic stress conditions, in particular cold, saline and osmotic stress.  The description identifies use of the regulatory elements of these stress-responsive genes along with reporter genes (chloramphenicol acetyltransferase, CAT; ß-glucuronidase, GUS; green fluorescent protein, GFP; ß-galactosidase, ß-GAL; luciferase) as a means to produce transgenic plants that can act as biosentinels that detect the presence of abiotic stress conditions.  The related journal publication of this technology is Cooper et al. (2003).  A network of rice genes associated with stress response and seed development.  Proc Natl Acad Sci USA. 100(8):4945-4950.

  • a method for identifying a polynucleotide involved in a stress response of a plant (claim 156)
  • a computor readable medium having stored executable instructions for comparing data on expression in a cell of a plant (claim 159)
  • a computor readable medium having stored a data structure comprising sequence data and a module (claim 161)

Definitions extracted from the specification are provided in CA 2420555.

Comments:

Since this is a published application and not a granted patent, there are no enforceable rights.

Dependent claims 146-151 are generally drawn towards a method to identify agents by use of bioreporter systems as follows:

  • a method to identify an agent that modulates the activity of the plant stress-regulated regulatory element (claim 146),
  • where the regulatory element may be linked to a heterologous nucleotide sequence (claim 147),
  • where the heterologous nucleotide sequence may encode for a reporter molecule (claim 148),
  • and the regulatory element/reporter system is in a plant (in vivo, in situ) or in vitro (claim 149),
  • where the plant (in claim 149) is a transgenic plant containing the regulatory element/reporter gene (claim 150),
  • that detects a stress mimicing agent (claim 151).
