  • Patent number: 9493782
    Abstract: 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.

  • Patent number: 8293975
    Abstract: 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.
