Nucleotide sequences of junctions of spontaneously induced λbio or λpro transducing phages. (a) Sequences of hot spot site I detected in the junctions of λbio transducing phages Q2, Q5, and Q34, which were isolated independently from unirradiated HI2034 recQ1802 λ lysogen. The sequences shown in boldface type represent homology at the recombination sites. The boxed sequences represent short regions and extra short regions of homology between the parental recombination sites. The map coordinates for phage and bacterial sequences are indicated. (b) Sequences of hot spot site II detected in the junctions of λbio transducing phages Q32, Q44, and Q49. (c) Sequences of hot spot site III detected in the junctions of λbio transducing phages Q1 and Q21. (d–g) Sequences of hot spots A, B, C, and D detected in the junctions of λpro transducing phages Q17, Q27, Q10, Q30, Q3, and Q7. (h) Sequences of a non-hot spot site detected in the junctions of λbio transducing phages Q17 and Q27. (i) Sequences of a non-hot spot site detected in the junctions of the λpro transducing phage PQ64.
