Abstract

Transformation of Bacillus subtilis by a plasmid requires a circular multimeric form. In contrast, linearized plasmids can be circularized only when homologous sequences are present in the host genome. A recombinational transfer system was constructed with this intrinsic B. subtilis recombinational repair pathway. The vector, pGETS103, a derivative of the θ-type replicating plasmid pTB19 of thermophilic Bacillus, had the full length of Escherichia coli plasmid pBR322. A multimeric form of pGETS103 yielded tetracycline-resistant transformants of B. subtilis. In contrast, linearized pGETS103 gave tetracycline-resistant transformants only when the recipient strain had the pBR322 sequence in the genome. The efficiency and fidelity of the recombinational transfer of DNAs of up to 90 kb are demonstrated.
