METHOD FOR PRODUCING PLANTS HAVING AN INCREASED TOLERANCE AGAINST DROUGHT AND/OR FUNGAL ATTACK AND/OR INCREASED SALT CONCENTRATIONS AND/OR EXTREME TEMPERATURE BY THE EXPRESSION OF PLASMODESMATA-LOCALIZED PROTEINS

摘要

The invention relates to the use of nucleic acids which code a (poly)peptide with an intrinsic affinity to plasmodesmata, to the production of plants or parts thereof having an increased tolerance against drought and/or fungal infections and/or increased salt concentrations and/or extreme temperature (heat, cold), and to corresponding methods. According to the invention, a plant, a plant tissue or a plant cell is advantageously transfected with the nucleic acid. The nucleic acid preferably codes a virus-coded transport protein which, in an especially preferred embodiment, is a derivative of the pr17 protein with a hydrophilic N-terminal extension.
