Bacterial genomes encode a rich repertoire of antiphage systems, but we still know surprisingly little about when these systems are actually expressed.
In this preprint, Lucas Paoli et al, ask what shapes antiphage systems expression in native contexts.

Bacteria and archaea encode on average ten antiphage systems. Quorum sensing, cellular, or transcription factors can regulate specific systems (CRISPR-Cas, CBASS). Yet, a systematic assessment of anti...
