title: Rex-centric mutualism.
abstract: We asked whether Rex exclusion encoded by a lambda prophage confers a protective or a cell-killing phenotype. We found that the Rex system can channel lysogenic cells into an arrested growth phase that gives an overall protective ability to the host despite some associated killing.
