Non-Parental-Type Recombinants In Crosses Between Different Restriction-Modification Systems In Salmonella, Mary Ball
Loma Linda University Electronic Theses, Dissertations & Projects
Many new restriction-modification (R-M) system which are closely linked to serB and allelic to the hsdSB system of S. typimurium occur in different Salmonella serotypes. In PI transduction studies with these systems, recombinants were isolated which fell into one of three classes with reference to their specific restriction phenotype. Recombinants that restricted like the donor, recombinants that restricted like the recipient and recombinants that had lost the ability to restrict. This latter group having lost the recipient SB restriction without gaining the specific donor restriction and here called "zero recombinants,” were of special interest and were investigated.
Zero recombinants …
