Abstract
Plants made resistant to insects by transforming their nuclear genome with two or more DNA sequences, each encoding a different non-competitively binding B. thuringiensis protoxin or insecticidal part thereof, preferably the toxin thereof.
Claims17
A plant, comprising stably inserted into the genome of its cells, at least two DNA sequences each encoding a different Bacillus thurningiensis (Bt) insecticidal crystal protein (ICP) or an insecticidal portion thereof, toxic to the same insect species, wherein the encoded Bt ICPs or the insecticidal portions thereof bind non-competitively to the brush border membrane of the midgut epithelial cells of said same insect species;
- and wherein said Bt ICPs or the insecticidal portions thereof are produced in said plant.
A plant, comprising stably inserted into the genome of its cells, at least two DNA sequences each encoding a different Bacillus thurningiensis (Bt) insecticidal crystal protein (ICP) or an insecticidal portion thereof, toxic to the same insect species, wherein the encoded Bt ICPs or the insecticidal portions thereof do not bind competitively to the brush border membrane of the midgut epithelial cells of said same insect species;
- and wherein said Bt ICPs or the insecticidal portions thereof are produced in said plant.
