Patent number: 9493782Abstract: The plant promoter of a CBSU-Anther_Subtraction library (CAS1) gene encoding a mannitol dehydrogenase, and fragments thereof, and their use in promoting the expression of one or more heterologous nucleic acid fragments in an inducible manner in plants are described. These promoter fragments are also useful in creating recombinant DNA constructs comprising nucleic acid sequences encoding a desired gene product operably linked to such promoter fragments which can be utilized to transform plants and bring the expression of the gene product under external chemical and/or heat control in monocotyledonous and dicotyledonous plants.Type: GrantFiled: May 17, 2013Date of Patent: November 15, 2016Assignee: PIONEER HI-BRED INTERNATIONAL, INC.Inventors: Andrew Mark Cigan, Erica Unger-Wallace

Patent number: 8293975Abstract: Methods are provided in which a promoter hairpin construct is introduced into a cell to suppress expression of a gene of interest; a change in phenotype of the cell, or of an organism regenerated from the cell, is detected; and the change in phenotype identifies the function of a product of the gene of interest. Also provided are methods for restoring the original phenotype.Type: GrantFiled: April 3, 2008Date of Patent: October 23, 2012Assignee: Pioneer Hi Bred International IncInventors: Andrew Mark Cigan, Erica Unger
