The toxin-antitoxin (TA) systems encoded on bacterial chromosomes have long been thought to act as effectors of a cellular stress response system. LeRoux et al. find that, despite strong transcriptional induction following various stress treatments, the toxins of TA systems are not activated under these conditions.

Stress Can Induce Transcription of Toxin-Antitoxin Systems without Activating Toxin
