ISOLATION AND USE OF THE DESICCATION-SPECIFIC PROMOTER FROM DS2 GENE

摘要

The present invention relates to an isolated single stranded or double stranded nucleic acid molecule comprising at least one regulatory gene region of plant origin that is drought-inducible and ABA-, salt- and cold-insensitive. In particular, the invention provides an isolated nucleic acid molecule comprising, in part or in its entirety, the 5' regulatory sequence region of the DS2 gene of a Solanaceae species, or orthologues, homologues or functional variants thereof. The present invention further provides transformation vectors, transgenic plants or any reproducible part thereof, and plant propagation materials, as well the use of the nucleic acid molecules as probe in screening methods, and a method for gene expression in plants, comprising expression of a gene in a drought-inducible and ABA-, salt- and cold-insensitive manner.
