Abstract:
In the past ten years, Listeria monocytogenes has emerged as a model organism in infection biology and also become an attractive system for the study of regulatory RNAs in pathogenic bacteria. Due to the recent completion of several transcriptomic studies, it is now clear that L. monocytogenes possesses a large repertoire of both cis- and trans-encoded RNAs. These include numerous small RNAs (sRNAs) expressed during infection, widespread transcription of both short and long antisense RNAs (asRNAs) and an array of cis-acting regulatory RNA elements. In this review we highlight the recent advances in non-coding RNA research in L. monocytogenes with a particular focus on emerging themes of RNA-based regulation.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
