aFor each CRISPR, we only checked for the presence of remote cas1-cas2 gene pair when no cas1-cas2 gene pair is found in the neighborhood of the CRISPR
-
bWhen lacking the CRISPRs, we examined the cas locus containing a nearby or remote cas1-cas2 gene pair. In this table, "+" indicates presence, "-" indicates absence, and a blank cell means the corresponding aspect was not checked
