Abstract
The subject invention concerns plants protected from nematode feeding damage and improved versions of Cry proteins. The subject invention also concerns improved versions of Cry12A proteins. Synthetic genes encoding these modified proteins are also part of the subject invention. Another embodiment of the subject invention includes plants transformed with the genes of the subject invention. In yet another embodiment the subject invention concerns Bt proteins for in-plant protection against crop damage by root knot nematode (RKN; Meloidogyne incognita) and soybean cyst nematode (SCN; Heterodera glycines).
Claims29
A transgenic plant that is resistant to damage by a nematode, wherein said resistance is due to expression of a polynucleotide that encodes a Cry12 protein that has toxin activity against said nematode.
A polynucleotide that encodes a modified Bacillus thuringiensis Cry12A protein having toxin activity against a nematode wherein said protein is truncated at the N terminus and/or at the C terminus, as compared to a corresponding full-length protein.
A polynucleotide that comprises a sequence selected from the group consisting of SEQ ID NO:
- 1, SEQ ID NO:
- 2, SEQ ID NO:
- 4, SEQ ID NO:
- 5, SEQ ID. NO:
- 7, SEQ ID NO:
- 8, SEQ ID NO:
- 10, SEQ ID NO:
- 11, SEQ ID NO:
- 13, SEQ ID NO:
- 14, and SEQ ID NO:
- 16.
A protein that comprises a sequence selected from the group consisting of SEQ ID NO:
- 3, SEQ ID NO:
- 6, SEQ ID NO:
- 9, SEQ ID NO:
- 12, SEQ ID NO:
- 15, and SEQ ID NO:
