Spacers from type IV systems preferentially target plasmid-borne protospacers. (A). Comparison of spacer–protospacer matches detected for type IV systems (left) and the co-occurring non-type IV systems (right). A more detailed breakdown, by CRISPR–Cas subtype/variant, is presented in Supplementary Table S4. (B). Distribution of type IV spacer hits on plasmids as a function of predicted plasmid mobility. (C). Size distribution of the targeted plasmids. The mobility prediction and size for the collection of PLSDB plasmids are displayed as a reference in both ‘B’ and ‘C’ plots.
