摘要:
The subject invention relates to insecticidal toxin complex (“TC”) fusion proteins and to polynucleotides that encode these fusion proteins. In some embodiments, the invention provides a fusion protein comprising a Class A protein, a Class B protein, and a Class C TC protein fused together to form a single protein. In some other embodiments, the invention provides a fusion protein comprising a Class B and a Class C TC proteins fused together. In the latter embodiments, the BC or CB fusion protein can be used to enhance or potentiate the anti-insect activity of a “Toxin A” or Class A protein. The subject invention also includes plants, cells (bacterial and plant cells for example), and seeds that comprise the polynucleotides. The subject invention also includes methods of controlling pests (preferably insects and other plant pests) with fusion proteins of the subject invention.

摘要:
The subject invention provides exciting new sources for surprising, new types of toxin complex (“TC”) proteins. The subject invention includes these new classes and types of TC proteins. The subject invention also includes polynucleotides that encode the subject proteins. The subject invention further provides vectors and cells comprising these polynucleotides. The subject invention also provides novel methods of controlling insects. The subject invention relates in part to the surprising discovery that new types of TC proteins can be obtained from a widely diverse phylogenetic spectrum of organisms including, most notably and surprisingly, eukaryotic fungus.

The present invention includes modified, insecticidal B.t. Cry1Ca proteins, including the proteins designated herein as DIG-109 and DIG-152, as well as variants of DIG-109 and DIG-152, nucleic acids encoding these proteins, methods of controlling pests using the proteins, methods of producing the proteins in transgenic host cells, and transgenic plants that produce the proteins. The DIG-109 and DIG-152 proteins comprise chimeric peptides composed of a core toxin segment of B.t. Cry1Ca and a Cry1Ab protoxin segment. Insecticidally active variants of the DIG-109 and DIG-152 proteins are also described.

The subject invention relates to insecticidal toxin complex (“TC”) fusion proteins and to polynucleotides that encode these fusion proteins. The subject invention also includes polynucleotides that encode the subject TC fusion proteins, and vectors comprising said polynucleotides. In some embodiments, the invention provides a fusion protein comprising a Class A protein, a Class B protein, and a Class C TC protein fused together to form a single protein. In some other embodiments, the invention provides a fusion protein comprising a Class B and a Class C TC proteins fused together. In the latter embodiments, the BC or CB fusion protein can be used to enhance or potentiate the anti-insect activity of a “Toxin A” or Class A protein. Heretofore, there was no expectation that such fusion proteins would properly function and retain their activity when fused together. The subject invention advantageously reduces the number of genes needed to transform plants. Thus, the subject invention also includes plants, cells (bacterial and plant cells for example), and seeds that comprise said polynucleotides. Said plants can produce fusion proteins of the subject invention, which convey insect resistance to said plants. The subject invention also includes methods of controlling pests (preferably insects and other plant pests) with fusion proteins of the subject invention.
摘要:
The subject invention relates to the surprising discovery that toxin complex (TC) proteins, obtainable from Xenorhabdus, Photorhabdus, and Paenibacillus, can be used interchangeably with each other. In particularly preferred embodiments of the subject invention, the toxicity of a “stand-alone” TC protein (from Photorhabdus, Xenorhabdus, or Paenibacillus, for example) is enhanced by one or more TC protein “potentiators” derived from a source organism of a different genus from which the toxin was derived. As one skilled in the art will recognize with the benefit of this disclosure, this has broad implications and expands the range of utility that individual types of TC proteins will now be recognized to have. Among the most important advantages is that one skilled in the art will now be able to use a single set of potentiators to enhance the activity of a stand-alone Xenorhabdus protein toxin as well as a stand-alone Photorhabdus protein toxin. (As one skilled in the art knows, Xenorhabdus toxin proteins tend to be more desirable for controlling lepidopterans while Photorhabdus toxin proteins tend to be more desirable for controlling coleopterans.) This reduces the number of genes, and transformation events, needed to be expressed by a transgenic plant to achieve effective control of a wider spectrum of target pests. Certain preferred combinations of heterologous TC proteins are also disclosed herein. Other objects, advantages, and features of the subject invention will be apparent to one skilled in the art having the benefit of the subject disclosure.
