A versatile plasmid marker rescue transformation system was developed for homology-facilitated cloning in Bacillus subtilis. It is based on the highly efficient host-vector system 6GM15-pHPS9, which allows the direct selection of recombinants by means of beta-galactosidase alpha-complementation. The

โฆ Synopsis
Resident deletion derivatives (Ems or Cms) of the streptococcal plasmid vector pGB301 rescue antibiotic resistance genes from linearized pGB301 (Emr, Cmr) DNA with high frequency. Insertion of passenger DNA next to an antibiotic resistance determinant of pGB301, which is missing on the resident plasmid, forces corescue of these two plasmid domains, thus allowing direct selection for recombinant plasmids.
