FIELD: chemistry.SUBSTANCE: present inventions relate to protein engineering, plant molecular biology and pest control, as well as a hybrid insecticide protein and use thereof. Described is a hybrid insecticide protein which includes from the N-end to the C-end an N-end portion of Cry3A protein which is fused with the C-end portion of Cry1Ab protein, wherein the position of the crossover of the Cry3A protein and the Cry1Ab protein is located in a conservative block 2, in a conservative block 3 or in a conservative block 4 and has anti-western corn rootworm activity. Also disclosed are nucleic acid molecules which code the novel proteins, methods of producing proteins, methods for use thereof, as well as transgenic plants and seeds thereof which contain such proteins.EFFECT: inventions enable to obtain cheap means of controlling Diabrotica worms.39 cl, 8 dwg, 9 tbl, 46 ex |
