DNA fragment encoding insecticidal crystal proteins from Bacillus thuringiensis

摘要

The invention relates to a vector for transforming microorganisms capable of undergoing sporulation and which contains itself a heterologous insert comprising a DNA sequence coding for at least part of crystal protein, particularly that of B. thuringensis. It also concerns the polypeptides expressed by said microorganisms and having insecticidal properties similar to those of crystal protein, the microorganisms themselves, as transformed by this vector and insecticidal composition including either said polypeptide or the microorganism itself.
