Identification of Escherichia coli Host Genes That Influence the Bacteriophage Lambda (λ) T4rII Exclusion (Rex) Phenotype.

Genetics - 1 Dec 2020

Alattas Hibah, Wong Shirley, Slavcev Roderick A

Abstract excerpt

The T4rII exclusion (Rex) phenotype is the inability of T4rII mutant bacteriophage to propagate in hosts (Escherichia coli) lysogenized by bacteriophage lambda (λ). The Rex phenotype, triggered by T4rII infection of a rex+ λ lysogen, results in rapid membrane depolarization imposing a harsh cellular environment that resembles stationary phase. Rex "activation" has been proposed as an altruistic cell death system...
