The Phage Time Continuum: Genome Organization Constrains Anti-CRISPR Success
Bacteria and lytic phages experience antagonistic co-evolution, with bacterial defenses (e.g., CRISPR-Cas) battling phage anti-defenses (e.g., anti-CRISPR (Acr) systems). We investigate whether CRISPR-Cas and Acr engage in a timing-dependent genetic conflict. If anti-CRISPR genes act too late in infection, they risk failing to neutralize CRISPR, if Cas cannot find its target in time, Acr may be…
