Patent number: 9127076Abstract: This invention relates in part to modifying BtBooster (BtB) peptides, in part to increase their stability in insect midgut digestive juices. Some preferred embodiments of BtB have removed proteinase cleavage sites resulting in increased stability of the modified BtB in the insect gut, while retaining the ability to enhance B.t. proteins for improved insect control. In some preferred embodiments, the protease-stable BtB is used in combination with B.t. spores and/or crystals comprising a Cry protein. Also reported herein is the significant and increased enhancement of Bt toxins against relatively Bt-tolerant insects (Helicoverpa zea, Spodoptera exigua and Agrotis ipsilon), when used with BtBs. We also describe increased toxin enhancement with cadherin fragments that are stabilized against over-digestion by insect midgut proteinases. We also report enhancement of Bt Cry1F toxin by cadherin fragments.Type: GrantFiled: August 11, 2008Date of Patent: September 8, 2015Assignee: The University of Georgia Research FoundationInventors: Mohd Amir-Fursan Abdullah, Michael J.

Patent number: 8486887Abstract: The subject invention relates in part to the discovery that a fragment from a cadherin of the western corn rootworm enhances Cry3 toxicity to larvae of naturally susceptible species. The subject invention also relates in part to the discovery that a cadherin fragment from a beetle enhances Cry3Aa and Cry3Bb toxicity to coleopteran larvae, particularly those in the family Chrysomelidae. Such cadherin fragments are referred to as Bt Boosters (BtBs). The subject invention can be extended to the use of BtBs with other coleopteran-toxic Cry proteins for controlling a wide range of coleopterans.Type: GrantFiled: August 11, 2008Date of Patent: July 16, 2013Assignee: The University of Georgia Research Foundation, Inc.Inventors: Michael J.

Patent number: 8101568Abstract: The subject invention pertains to the use of peptide fragments of cadherins (including cadherin-like proteins). The subject invention includes a cell (and use thereof) comprising a polynucleotide that expresses the peptide fragment. The subject invention includes methods of feeding the peptides to insects. In preferred embodiments, the peptides are fed to target insects together with one or more insecticidal proteins, preferably (but not limited to) B.t. Cry proteins. When used in this manner, the peptide fragment can not only enhance the apparent toxin activity of the Cry protein against the insect species that was the source of the receptor but also against other insect species. Preferably, the cadherin is a Bacillus thuringiensis (B.t.) insecticidal crystal protein (Cry) toxin receptor. Preferably, the peptide fragment is a binding domain of the receptor. In some preferred embodiments, the peptide is the binding domain nearest to the membrane proximal ectodomain.Type: GrantFiled: June 27, 2008Date of Patent: January 24, 2012Assignee: University of Georgia Research Foundation, Inc.Inventors: Michael J. Adang, Gang Hua, Jian (John) Chen, Mohd Amir Fursan Abdullah

Publication number: 20110112012Abstract: The subject invention relates in part to a novel protein for binding Bacillus thuringiensis Cry toxins, and fragments of cadherins for enhancing Cry toxicity against dipterans. The subject invention also relates in part to the discovery that fragments of a midgut cadherin from a dipteran insect synergize Cry proteins that are active against dipterans. Thus, the subject invention includes the use of fragments of cadherin ectodomains for controlling dipterans. Such fragments (that bind Crys) can be administered to a dipteran insect for ingestion. In some preferred embodiments, the source cadherin is a dipteran cadherin. Also in some preferred embodiments, the fragment is administered with a Cry protein that is active against a dipteran. Variants of the fragments of naturally occurring cadherins are included within the scope of the subject invention.Type: ApplicationFiled: April 3, 2009Publication date: May 12, 2011Applicants: The University of Georgia Studies Research Foundation ,Inc., InsectiGen ,Inc.Inventors: Michael J.
