This study identifies an isolated CRISPR array in Pseudomonas aeruginosa that is horizontally transferred and contributes to CRISPR-mediated immunity through recombination with mobile genetic elements.

This study characterizes EsAgo, a prokaryotic Argonaute from Exiguobacterium sp. AB2, showing it can cleave DNA with or without guides and has potential biotechnological applications.

This study uses experimental evolution to test the necessity of chemotaxis pathway components in E. coli, finding that core components are essential but some auxiliary proteins can be compensated for.
