    摘要: Bacillus thuringiensis endotoxin expression in Pseudomonads can be improved by modifying the gene encoding the Bacillus thuringiensis endotoxin. Chimeric genes are created by replacing the segment of the Bacillus thuringiensis gene encoding a native protoxin with a segment encoding a different protoxin. Exemplified herein is the cryIF/cryI(b) chimera wherein the native cryIF protoxin segment has been substituted by the cryIA(b) protoxin segment, to yield improved expression of the cryIF toxin in Pseudomonads. The invention also concerns novel genes and plasmids.
