Summary Mutations c17 and ri c, which permit constitutive expression of genes O and P and transcriptional activation of λ DNA replication, act as new promoters since they map outside the immunity region and direct rightward transcription in the presence of repressor. In the λc17 P -or λri cP- lysogens, this constitutive transcription is restricted to the O-P region, and is at least one order of magnitude lower than that for an induced λP -lysogen. The operator-constitutive mutants v2 and v1v3 give very low levels of constitutive transcription from the l and r strands, respectively.
