From: Long reads reveal the diversification and dynamics of CRISPR reservoir in microbiomes
A compressed spacer graph representing diversification of CRISPR arrays via extensive spacer gains. In (a), the nodes are colored according to their topological property with source nodes (which are likely more recently gained spacers than the rest) shown in blue and the sink node (the conserved spacer in the trailer end) in yellow. In (b), the nodes representing spacers with matching co-occurring protospacers (found in the same microbiome) are shown in red
