Compendium of RNA modifications for bacterial stress adaptation

Area of Science:

• Molecular Biology
• Genetics
• Microbiology

Background:

• RNA modifications form the epitranscriptome, a key layer of post-transcriptional gene regulation.
• In bacteria, tRNA and rRNA modifications are established, influencing vital processes like translation.
• The role and extent of mRNA modifications in prokaryotes are emerging research areas.

Purpose of the Study:

• To review current knowledge of modified RNA nucleotides in bacteria.
• To highlight the functional implications of RNA modifications in prokaryotes.
• To focus on the role of the bacterial epitranscriptome in adaptation to environmental stress.

Main Methods:

• Literature review of bacterial RNA modification research.
• Analysis of existing studies on tRNA, rRNA, and mRNA modifications in prokaryotes.
• Synthesis of findings related to bacterial adaptation and stress response.

Main Results:

• While tRNA and rRNA modifications are well-characterized in bacteria, mRNA modifications are less understood.
• RNA modification is a dynamic process significantly affecting bacterial physiology.
• Variations in RNA modification abundance and presence are linked to bacterial adaptation.

Conclusions:

• The bacterial epitranscriptome, particularly mRNA modifications, is a critical but understudied area.
• Further research into bacterial RNA modifications is essential for understanding adaptation and stress responses.
• The epitranscriptome represents a promising target for future investigations into bacterial survival mechanisms.
