Patent 7525016 was granted and assigned to Iowa State University on April, 2009 by the United States Patent and Trademark Office.
The present invention relates to the isolation, purification, sequencing, and functional characterization of the class I and II terpene sequences OsCPS1ent, OsCPS2ent, OsCPS4syn, and OsDTS2. Transcriptional control of OsCPS1ent provides a means of regulating production of gibberellin phytohormone, while transcriptional control of OsCPS2ent, OsDTS2, and OsCPS4syn provides a means of regulating defensive phytochemical biosynthesis. Further, these enzymatic genes offers a means by which terpenoid production may be more generally modulated, specifically including genetic engineering, as well as ex vivo uses.
