Efficiency of homologous intermolecular recombination at different locations on the Bacillus subtilis chromosome.
The efficiencies of intermolecular recombination at 12 different locations on the Bacillus subtilis chromosome were determined by transforming competent cells with a nonreplicative plasmid. The efficiencies varied by only about threefold but were significantly different (P less than 0.05 by a chi-square test) for approximately 20% of the locations. The recA gene product is required for recombination, and the addA gene product appears to affect the variation in a site-specific way.
