MODIFIED Cry1Ca TOXINS USEFUL FOR CONTROL OF INSECT PESTS

Abstract

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.

1 - 17 . (canceled) 
     
     
         18 . A nucleic acid sequence chosen from the group consisting of SEQ ID NO:29, SEQ ID NO:31, SEQ ID NO:33, and SEQ ID NO:35. 
     
     
         19 . A transgenic plant, plant part, or seed comprising a nucleic acid sequence of  claim 18 . 
     
     
         20 . The transgenic plant, plant part, or seed of  claim 19  chosen from the group consisting of maize, sunflower, soybean, cotton, canola, rice, sorghum, wheat, barley, vegetables, ornamentals, peppers, sugar beets, fruit, and turf grass. 
     
     
         21 . The transgenic plant, plant part, or seed of  claim 19  chosen from the group consisting of maize, soybean and cotton. 
     
     
         22 . The transgenic plant, plant part, or seed of  claim 19  that is maize. 
     
     
         23 . The transgenic plant, plant part, or seed of  claim 19  that is soybean. 
     
     
         24 . The transgenic plant, plant part, or seed of  claim 19  that is cotton. 
     
     
         25 . A method of controlling plant insect pests which comprises growing transgenic plants that comprise a nucleic acid sequence of  claim 19 , and allowing susceptible pests to feed on said transgenic plants. 
     
     
         26 . A method of controlling plant insect pests that have developed resistance to other Cry toxins which comprises growing transgenic plants that comprise a nucleic acid sequence of  claim 19 , and allowing susceptible pests to feed on said transgenic plants.
