| abstract |
The invention relates to a method for producing or increasing resistance against at least one biotic or abiotic stress factor in plants, preferably against plant pathogens, by increasing expression of at least one Bax inhibitor 1 (BI1) protein in at least one plant tissue, under the proviso that expression in leaf epidermis remains substantially unmodified. The invention relates further to recombinant expression cassettes and vectors that comprise a nucleic acid sequence coding for the BI protein under the control of a tissue-specific promoter, said promoter having substantially no activity in leaf epidermis. The invention further relates to recombinant plants that are transformed with said expression cassettes or vectors, to cultures, parts or recombinant propagation material derived thereof, and to the use of the same for producing food, feeding stuff, seeds, pharmaceuticals or fine chemicals. |
