The plasmid pC 194 from one successful transformant, strain O 016-194, was subsequently transferred to B. thuringiensis subsp. israelensis by a "conjugation-like" process. The plasmid pBC 16 from B. cereus could also be transferred to B. thuringiensis subsp. israelensis with high frequency using the conjugation-like process. Further, both plasmids, pC 194 and pBC 16, were transferred between strains of B. thuringiensis subsp. israelensis to yield transcipient strains that harbored and expressed properties of both plasmids. This work constitutes effective gene transfer system in B. thuringiensis subsp. israelensis. © 1986.Mahidol UniversityAgricultural and Biological SciencesArticleSCOPUS10.1016/0022-2011(86)90061-3
