Bacterial immunity: Mobile genetic elements are hotspots for defence systems

Abstract

A new study reports that phage-inducible chromosomal islands (PICIs) are hotspots of defence systems against phages, other PICIs and plasmids. This discovery highlights how competition between mobile genetic elements shapes bacterial defence gene repertoires and helps to better understand how defence systems are exchanged among bacteria.
