The Escherichia coli CRISPR System Protects from λ Lysogenization, Lysogens, and Prophage Induction

Rotem Edgar, Udi Qimron

Abstract

We show that phage lysogenization, lysogens, and prophage induction are all targeted by CRISPR. The results demonstrate that genomic DNA is not immune to the CRISPR system, that the CRISPR system does not require noncytoplasmic elements, and that the system protects from phages entering and exiting the lysogenic cycle.
