Claims
- 1. An isolated DNA fragment which is a plant enhancer capable of activating or enhancing the transcription level of a plant-expressible gene, said enhancer element comprising a consensus sequence selected from the group consisting of ##STR4## and its reverse sequence.
- 2. A DNA fragment of claim 1 comprising the sequence 5'-ACGTAAGCGCTTACGT-3'.
- 3. A DNA fragment of claim 1 wherein the consensus sequence is repeated.
- 4. A DNA fragment comprising the consensus sequence of claim 1 and also comprising a second component consisting essentially of a sequence selected from the group consisting of 5'-GATGTTAACATC-3' and its reverse sequence.
- 5. The DNA fragment of claim 1 wherein said plant enhancer element is derived from T-DNA.
- 6. The DNA fragment of claim 1 wherein said plant enhancer element is derived from the 5' untranscribed region cf the octopine synthase gene of T-DNA.
- 7. The DNA fragment of claim 1 wherein said plant enhancer element has been chemically synthesized.
