摘要：
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.
