A plant universal stress-inducible regulatory element comprises 5 min -flanking DNA sequences of a plant gene which exhibits induced synthesis in response to a variety of environmental stresses, e.g., heat shock, osmotic pressure, salt stress, heavy metal ion concentration, partial anaerobiosis, etc. The isolation, characterization and utility of such a regulatory element is disclosed. The plant universal stress-inducible regulatory element contains promoter functionality, associated with sites of initiation of transcription, as well as regulatory function associated with the induction response to a variety of stresses. Methods are provided for inducing an increased level of expression of plant-expressible genes in plant tissue in response to environmental stress. |
