Abstract

Summary: The k, b and phage P1 host specificity genes were introduced into by means of Hfr × F crosses. The three systems were found to govern modification and restriction of phages P22 and L. The restriction coefficients were comparable to that of λ for the P1 system and were lower (about 100) for the k and b systems. Phage grown on and recombinants was restricted by independently of the restriction governed by the lt system. This observation suggested that possesses a previously undetected locus allelic to those of K and b.
