Bacterial alginate regulators and phage homologs repress CRISPR-Cas immunity.

abstract：:Many insects, including mosquitoes, planthoppers, aphids and leafhoppers, are the hosts of bacterial symbionts and the vectors for transmitting viral pathogens1-3. In general, symbiotic bacteria can indirectly affect viral transmission by enhancing immunity and resistance to viruses in insects3-5. Whether symbiotic ba...

abstract：:Bacteria have evolved diverse mechanisms to fend off predation by bacteriophages. We previously identified the Dnd system, which uses DndABCDE to insert sulfur into the DNA backbone as a double-stranded phosphorothioate (PT) modification, and DndFGH, a restriction component. Here, we describe an unusual SspABCD-SspE P...
