摘要

FIELD: agricultural biotechnology, biological plant protection against injurious insects. SUBSTANCE: purified and isolated DNA fragment Cry IIIC that contains nucleotide sequence of bases coding amino acid sequence of protein Cry IIIC is obtained from new strain of Bacillus thuringiensis. Toxic protein Cry IIIC is efficient at its application in insecticide compositions while fighting against coleopterous insects. EFFECT: higher efficiency of plant protection. 8 cl, 4 cl, 7 tbl, 12 dwg
