Here, the authors investigate the diversity and dynamics of the CRISPRome in the hyperthermophilic archaea of the order Sulfolobales, and find the most abundant spacers to come from mini-CRISPR arrays of archaeal viruses, which might represent a strategy for superinfection exclusion and promotion of archaeal virus speciation.
