Abstract

There are described 5' transcriptional regulatory regions of plant genes which ensure sink organ specific expression of cis-linked DNA sequences as well as recombinant double stranded DNA molecules comprising these 5' regulatory regions. Furthermore the present invention relates to a method for producing transgenic plants which show a sink tissue specific expression of a desired DNA sequence.
