    Notes: Summary Haploid hybrids between Salmonella typhimurium Hfr and Escherichia coli Fexercise two additive types of restriction and modification (SA and SB) on phage γ. System SA had been detected previously in S. typhimurium with phage L. Independent mutants in the SA and SB systems were isolated. P22- and P1-mediated transductions in S. typhimurium and in hybrids established that the genes governing these systems are independent but linked and situated counter-clockwise of serB on the map, in the order: pyrB-hsd SA-hsd SB-serB.

    Notes: Summary E. coli x S.typhimurium partially diploid hybrids were constructed to investigate the possibility of genetic complementation between the SA and the SB restriction and modification systems of S. typhimurium and the K and B systems of E. coli. An hsdR K - mutation was complemented in a stable hybrid in which the hsd SA + -hsd SB + -serB + portion of the S. typhimurium chromosome was integrated at a non-homologous locus. By isolating hsd - mutants in that hybrid, it was shown that complementation occured between K and SB, but not between K and SA. Similarly, in a set of F-prime merodiploids bearing the SA, SB and B systems, complementation was observed between B and SB, but not between B and SA.
