Compendium of RNA modifications for bacterial stress adaptation | Microbiology and Molecular Biology Reviews
SUMMARYRNA modifications in the tRNA, rRNA, and mRNA constitute a widespread layer of post-transcriptional gene regulation, commonly known as the epitranscriptome. In bacteria, tRNA and rRNA modifications are well documented and play essential roles in tRNA folding, rRNA maturation, translation, and peptidyl transfer. Although mRNA modifications have been extensively characterized in eukaryotes, their functional implications for mRNA fate in prokaryotes remain uncertain, and their identities and locations are the subject of an emerging field of research. Importantly, RNA modification is a dynamic process, and variation in the presence and abundance of these modifications has significant consequences for bacterial physiology. Here, we discuss current knowledge of modified RNA nucleotides in bacteria, with a particular focus on their roles in bacterial adaptation to environmental stress.
