Abstract
The plasmid pHT409 that harbours the cryIA(a) gene for the production of a δ-endotoxin (crystal protein) from Bacillus thuringiensis was transferred into Bradyrhizobium sp. A conjugal transfer system aiming to introduce the plasmid into the Bradyrhizobium sp. host from colonies of an Escherichia coli donor strain (DH5α::pHT409) has been developed. As a result exconjugants were obtained in which the transferred plasmid has been detected by both microbiological and electrophoresis techniques. The cryIA(a) gene when inside the new host had a low expression level which was detected by immunoblotting.
