ARTIFICIAL PROMOTER FOR THE EXPRESSION OF DNA SEQUENCES IN VEGETAL CELLS

摘要

The invention relates to an artificial promoter which is characterised in that it comprises a chimeric molecule of recombinant DNA which, once introduced into plant cells of any class, promotes high expression levels of any DNA molecule that is fused to the 3' end thereof. The basic genetic elements of the inventive promoter molecule are as follows: a promoter nucleus with a consensus TATA box followed by an Exon/Intron/Exon region and a translational activity-potentiating element, all of which are produced artificially. Transcriptional expression-regulating elements can be inserted upstream of the promoter in order to provide the expression with the specific time-response capacity of organ or tissue. The artificial genetic elements designed can be functionally inserted between any active promoter in plant cells and any DNA sequence in order to increase the transcription/translation levels of the latter.
