The evolutionary arms race between bacteria and phages has driven the development of diverse anti-phage defense mechanisms. Recent studies have identified noncoding RNAs (ncRNAs) as key players in bacteria-phage conflicts, including CRISPR-Cas, toxin-antitoxin (TA), and reverse transcriptase (RT)-based defenses; however, our understanding of their roles in immunity is still emerging. In this review, we explore the multifaceted roles of ncRNAs in bacterial immunity, offering insights into their contributions to defense and anti-defense mechanisms, their influence on immune regulatory networks, and potential biotechnological applications. Finally, we highlight key outstanding questions in the field to spark future research directions.
期刊介绍:
Trends in Microbiology serves as a comprehensive, multidisciplinary forum for discussing various aspects of microbiology, spanning cell biology, immunology, genetics, evolution, virology, bacteriology, protozoology, and mycology. In the rapidly evolving field of microbiology, technological advancements, especially in genome sequencing, impact prokaryote biology from pathogens to extremophiles, influencing developments in drugs, vaccines, and industrial enzyme research.
