[Cloning of the purA16 locus in Rec+ cells of Bacillus subtilis].
A portion of purA16 chromosomal locus of Bacillus subtilis was cloned into Rec+ cells of this microorganism with pBD12 plasmid (carrying chloramphenicol and kanamycin resistance determinants) serving as a vector. The hybrid plasmids were stably maintained in cells grown on media supplemented with antibiotics and were lost from cells in the absence of drugs. The cloned fragment could incorporate into the chromosome some with a frequency of 10(-2) per cell per generation. A clone carrying the hybrid plasmid inserted into the chromosome was detected.
