Abstract
The disclosure relates to Bt toxin resistance management. One embodiment relates to the isolation and characterization of polynucleotides and polypeptides corresponding to novel Bt toxin receptors. The polynucleotides and polypeptides are useful in identifying or designing novel Bt toxin receptor ligands including novel insecticidal toxins.
Claims10
-20. (canceled)
A method for altering the susceptibility of an insect to an insecticidal toxin, said method comprising:
- a. identifying in an insect
- a genomic nucleotide sequence having at least 90% sequence identity to any one of SEQ ID NO:
- 1, 3, 5, 7, or 9;
- b. editing the identified genomic nucleotide sequence;
- and
- c. selecting for altered susceptibility of said insect.
-25. (canceled)
A genetically modified insect comprising an edited genomic sequence, where the genomic sequence encoded an insecticidal toxin receptor prior to editing.
A method of making an insect resistant to an insecticidal toxin, comprising:
- a. Editing an insect genomic sequence, wherein the genomic sequence encodes an insecticidal toxin receptor;
- and
- b. Selecting an insect having increased resistance to an insecticidal toxin.
