a The phylogeny of consensus direct repeat (DR) sequences across Enterobacteriaceae. Neighbour-joining tree was constructed based on distance matrix analysis of the consensus DR sequences. b The phylogeny of last direct repeat (Last DR) sequences across Enterobacteriaceae. Neighbour-joining tree was constructed based on distance matrix analysis of the Last DR sequences

The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR-associated (Cas) system is a bacterial and archaeal adaptive immune system undergoing rapid multifaceted evolution. This evolution plausibly occurs due to the genetic exchanges of complete loci or individual entities. Here, we systematically investigate the evolutionary f...
