title: Transformation and expression of a cloned delta-endotoxin gene in Bacillus thuringiensis.
abstract: A shuttle vector containing the replication region of a resident plasmid of B. thuringiensis, was used to determine the conditions allowing efficient transformation of B. thuringiensis by electroporation. Using this plasmid a delta-endotoxin gene was cloned and expressed both in Escherichia coli and B. thuringiensis. It was shown that this gene was poorly expressed in the wild type situation whereas after cloning in acrystalliferous strains of B. thuringiensis large amounts of crystal protein were obtained.
