CRISPR control of virulence in Pseudomonas aeruginosa
MetadataShow full item record
Clustered regularly interspaced short palindromic repeats (CRISPR) and their associated genes (cas) are essential components of an adaptive immune system that protects bacteria and archaea from viral infection. Now a recent paper published in Cell Research suggests that the Type I-F immune system in Pseudomonas aeruginosa may also be involved in post-transcriptional regulation of virulence.
