摘要

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.
