High viral abundance and low diversity are associated with increased CRISPR-Cas prevalence across microbial ecosystems
CRISPR-Cas are adaptive immune systems that protect their hosts against viruses and other parasitic mobile genetic elements.(1) Although widely distributed among prokaryotic taxa, CRISPR-Cas systems are not ubiquitous.2, 3, 4 Like most defense-system genes, CRISPR-Cas are frequently lost and gained,...
