  • Modified Bacillus thuringiensis genes with improved expression in plant cells, methods of production on and use
    Patent number: 5952547
    Abstract: The invention relates to modified Bacillus thurigiensis genes with improved expression in plant cells, their preparation and uses. The invention relates more particularly to DNA fragments encoding all or part of a Bt insecticidal crystal protein, modified by translationally neutral modification(s) in cryptic promoter(s) and/or abortive intron(s). The invention also discloses method of preparing such modified DNAs, and methods of protecting plants from an insect pest.

  • Modified Bacillus thuringiensis insecticidal-crystal protein genes and their expression in plant cells
    Patent number: 5877306
    Abstract: A DNA fragment, encoding all or an insecticidally-effective part of a Bt crystal protein, is modified by changing A and T sequences to corresponding G and C sequences encoding the same amino acids, in a region having transcriptional activity less than 25% of the transcriptional activity of a region at the translation initiation site.
