Nucleic acid molecules encoding novel

1. An isolated DNA sequence encoding a truncated insecticidal Cry2Ae protein consisting of the amino acid sequence of the protein of SEQ ID NO: 2 from amino acid position 1 to an amino acid position between amino acid position 625 and amino acid position 632.

2. A chimeric gene comprising the DNA sequence of claim 1 , wherein said DNA sequence is under the control of a promoter which can direct expression of the gene in a plant cell.

3. The chimeric gene of claim 2 , further comprising a DNA encoding a targeting or transit peptide which is operably-linked to said DNA encoding said Cry2Ae protein, wherein said targeting or transit peptide is a peptide targeting to the vacuole, mitochondrium, chloroplast, plastid, or for secretion.

4. A plant cell, plant or seed transformed to comprise the chimeric gene of claim 2 .

5. A plant cell, plant or seed transformed to comprise the chimeric gene of claim 3 .

6. The plant cell, plant or seed of claim 4 , wherein said cell, plant or seed are of corn, cotton, rice, tobacco, oilseed rape, Brassica species, eggplant, soybean, potato, sunflower, tomato, sugarcane, tea, beans, strawberry, clover, cucumber, watermelon, pepper, oat, barley, wheat, dahlia, gladiolus, chrysanthemum, sugarbeet, sorghum, alfalfa, or peanut.

7. The plant cell, plant or seed of claim 5 , wherein said cell, plant or seed are of corn, cotton, rice, tobacco, oilseed rape, Brassica species, eggplant, soybean, potato, sunflower, tomato, sugarcane, tea, beans, strawberry, clover, cucumber, watermelon, pepper, oat, barley, wheat, dahlia, gladiolus, chrysanthemum, sugarbeet, sorghum, alfalfa, or peanut.

8. A process for rendering a plant resistant to an insect, wherein said method comprises transforming plant cells with the chimeric gene of claim 2 , and regenerating transformed plants from such cells.

9. The chimeric gene of claim 2 , wherein said promoter is a promoter whose expression in plants is inducible by insect feeding.

10. A chimeric gene comprising the following operably-linked elements:

(a) a promoter region which is a DNA sequence from the Cauliflower Mosaic Virus 35S promoter;

(b) a DNA from the leader sequence of the chlorophyll a/b binding protein gene from Petunia;

(c) a DNA encoding the TpssuAT transit peptide;

(d) the DNA of claim 1 ; and

(e) a 3′ transcript termination and polyadenylation region which is a DNA sequence from the 3′ transcript termination and polyadenylation region of the Cauliflower Mosaic Virus 35S gene.

11. A process for rendering a plant resistant to an insect, comprising transforming plant cells with the chimeric gene of claim 10 or 9 , and regenerating transformed plants from such cells which are resistant to insects.

12. A method for controlling insects comprising expressing in transformed plant cells an insecticidally-effective amount of said truncated insecticidal Cry2Ae protein encoded by the DNA of claim 1 , to control Heliothis virescens, Helicoverpa zea, Helicoverpa armigera, Anticarsia gemmatalis and Ostrinia nubilalis, Chilo suppressalis, Chilo partellus, Scirpophaga incertulas, Sesamia inferens, Cnaphalocrocis medinalis, Marasmia patnalis, Marasmia exigua, Marasmia ruralis , or Scirpophaga innotata.

13. An isolated DNA sequence encoding a truncated insecticidal Cry2Ae protein consisting of the amino acid sequence of the protein of SEQ ID NO: 2 comprising a C-terminal deletion up to amino acid position 625.

14. An isolated DNA sequence encoding a truncated insecticidal Cry2Ae protein consisting of the amino acid sequence of the protein of SEQ ID NO: 2 comprising an N-terminal deletion up to amino acid position 50 and a C-terminal deletion up to amino acid position 625.
