Abstract

The subject invention relates to insecticidal toxin complex (“TC”) fusion proteins and to polynucleotides that encode these fusion proteins. In some embodiments, the invention provide 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 compromising a Class B and a Class C TC proteins fused together. In the latter embodiments, the BC and CB fusion protein can be used to enhance or potentate 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 polynueleotides. The subject invention also includes methods of controlling pests (preferably insects and other plant pests) with fusion proteins of the subject invention.
