Summary Entry of DNA from λ phages particles into λrMal- mutants of Escherichia coli K-12 is shown to be due to two distinguishable processes. One, residual transduction, results from a low level expression of lamB. The other one, background transduction, is independent of gene lamB. Interpretations are presented for these results. It is proposed that residual transduction is due to a weak promoter pB3 located within or near the distal part of the gene preceeding lamB in the same operon. It is proposed that background transduction is due to a secondary receptor structure for phage λ. Finally a tentative hypothesis relating pB3 to insertion sequences is presented.
