Abstract
During transformation of B. subtilis cells with the Bsu R restriction-modification system by means of pUB110 plasmid restriction and modification of the plasmid DNA occurs. The effect of restriction on the transformation frequency is relatively weak, bringing about 20-fold decrease only. When using cells of a modifying recipient, the frequency of AR9 phage-mediated transduction of unmodified plasmid DNA is also relatively little decreased. The frequency of transduction by chromosomal markers, under the same conditions, falls much lower.
