Patent number: 7364728Abstract: This invention is a method for constructing recombinant organisms that produce proteins lethal to the larvae of insects. Nucleotide sequences were isolated from Bacillus popilliae that encode two adjacent, putative genes; orf1 and cryhime1. The cryhime1 sequence was related to other Bacillus popilliae genes that encode proteins active against Scarabaeidae insect larvae. When these nucleotide sequences were transferred to Bacillus thuringiensis, a protein was produced that had a lethal effect on the larvae from Scarabaeidae insects. When the orf1 sequence was removed from the recombinant Bacillus thuringiensis strain, no protein active against Scarabaeidae insect larvae was produced, strongly suggesting that the orf1 sequences are required for expression of the cryhime1 gene.Type: GrantFiled: March 1, 2005Date of Patent: April 29, 2008Assignee: Phyllom LLCInventors: Shin-ichiro Asano, Mikiko Nozawa, Hisanori Bando

Patent number: 7361751Abstract: Four novel Bacillus thuringiensis strains, which are deposited at the BCCM-LMG under accession nos. LMG P-12592, LMG P-12593, LMG P-12594, and LMG P-13493, produce new crystal proteins during sporulation that are toxic to Lepidoptera, more particularly against Noctuidae such as Spodoptera spp. and Agrotis ipsilon, against Pyralidae such as Ostrinta nubilalis, and against Yponomeutidae such as Plutella xylostella, and that are encoded by a novel gene.

Patent number: 6833449Abstract: Disclosed is a method for improving the expression of Cry1A in plants that makes use of codons preferentially used in native plant genes. The coding sequence of the gene for the Bacillus thuringiensis delta endotoxin Cry1A crystal protein was analyzed and found to have codons not preferred by plants. By constructing a synthetic protein coding sequence that uses codons which are preferred in plant genes, expression of the protein in plant cells was improved.Type: GrantFiled: March 21, 2003Date of Patent: December 21, 2004Assignee: Monsanto Technology LLCInventors: Kenneth A. Barton, Michael J. Miller

Publication number: 20040254364Abstract: Disclosed herein are activated Bt toxins expressed in E. coli as a translational fusion with a phage coat protein of filamentous phage. Phage displaying this fusion protein were viable, infectious, and as lethal as pure toxin on a molar basis when fed to insects susceptible to native Bt toxins.Type: ApplicationFiled: April 20, 2004Publication date: December 16, 2004Inventors: Michael J. Adang, Laura M. Kasman

Patent number: 6831062Abstract: The subject invention pertains to B.t. toxins active against pests. More specifically, the subject invention pertains to truncated Cry6A toxins. These activated toxins are particularly effective for controlling coleopteran pests such as the corn rootworm and the alfalfa weevil.Type: GrantFiled: October 15, 2001Date of Patent: December 14, 2004Assignee: Mycogen CorporationInventors: Mark Thompson, Mark Knuth, Guy Cardineau

Patent number: 6780408Abstract: The present invention provides, inter alia, a B.t. hybrid toxin fragment comprising at its C-terminus domain III of a first Cry protein, or a part of said domain or a protein substantially similar to said domain; and comprising at its N-terminus the N-terminal region of a second Cry protein, or a part of said region or a protein substantially similar to said region.Type: GrantFiled: September 22, 2000Date of Patent: August 24, 2004Assignee: Syngenta Participations AGInventors: Hendrik Jan Bosch, Willem Johannes Stiekema

Patent number: 6737273Abstract: Novel Bacillus thuringiensis genes encoding toxins which are active against lepidopteran insects have been cloned from novel lepidopteran-active B. thuringiensis microbes. The DNA encoding the B. thuringiensis toxins can be used to transform various prokaryotic and eukaryotic microbes to express the B. thuringiensis toxins. These recombinant microbes can be used to control lepidopteran insects in various environments.Type: GrantFiled: April 19, 2001Date of Patent: May 18, 2004Assignee: Myocogen CorporationInventors: Jewel Payne, August J. Sick

Patent number: 6727409Abstract: Four novel Bacillus thuringiensis strains, which are deposited at the BCCM-LMG under accession nos. LMG P-12592, LMG P-12593, LMG P-12594, and LMG P-13493, produce new crystal proteins during sporulation that are toxic to Lepidoptera, more particularly against Noctuidae such as Spodoptera spp. and Agrotis ipsilon, against Pyralidae such as Ostrinta nubilalis, and against Yponomeutidae such as Plutella xylostella, and that are encoded by a novel gene. The crystal proteins contain protoxins, which can yield a toxin as trypsin-digestion product. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that encodes its respective toxin, is resistant to Lepidoptera. Each strain, itself, or its crystals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Lepidoptera.Type: GrantFiled: December 28, 1998Date of Patent: April 27, 2004Assignee: Bayer BioScience N.V.Inventors: Bart Lambert, Stefan Jansens, Katrien Van Audenhove, Marnix Peferoen

Patent number: 6692750Abstract: The present invention is directed to alphavirus expression vectors comprising at least part of an alphavirus genome and heterologous RNA inserted downstream of an alphavirus base sequence having translation enhancing activity. Such vectors can be used to achieve enhanced levels of expression of DNA or cDNA coding for a desired product and being complementary to said heterologous RNA after introduction of said vector in eukaryotic cells in cell culture or in a living body. The expression product may have therapeutic or prophylactic activity.Type: GrantFiled: September 7, 2000Date of Patent: February 17, 2004Assignee: Bioption ABInventors: Mathilda Sjöberg, Maarit Suomalainen, Henrik Garoff

Patent number: 6689743Abstract: Disclosed claimed are toxins produced by novel Bacillus thuringiensis isolates designated B.t. PS92J, B.t. PS196S1, B.t. PS201L1, and B.t. PS201T6, which have dipteran and/or corn rootworm activity. Thus, the isolates, or mutants therof, can be used to control such pests. Further, claimed are novel genes encoding these &dgr;-endotoxins, which can be expressed in other hosts. Expression of the &dgr;-endotoxins in such hosts results in the control of susceptible insect pests in the environment of such hosts.Type: GrantFiled: November 3, 2000Date of Patent: February 10, 2004Assignee: Mycogen CorporationInventors: Jewel Payne, Kenneth E. Narva, Kendrick Akira Uyeda, Christine Julie Stalder, Tracy Ellis Michaels
