Beschreibung
Zusammenfassung:	The subject invention concerns Bacillus thuringiensis modified Cry1Ca insecticidal toxins and the polynucleotide sequences which encode these toxins. Uses in transgenic plants are described as are methods for protecting crops from insect pest damage. In one embodiment, there is provided a modified Cry1Ca toxin comprising an Ala54 modification that provides for resistance to chymotrypsin cleavage.
