Nucleic Acid Sensing in Plants

Nucleic acid sensing in plants is a defense mechanism that detects pathogen-associated molecular patterns, particularly foreign DNA and RNA. This recognition triggers immune responses, activating defense-related genes and proteins to fend off viral, bacterial, and fungal infections. Key players in this process include receptors like pattern recognition receptors (PRRs) and RNA interference pathways. Recent studies have unveiled complex molecular networks governing nucleic acid sensing, enhancing understanding of plant immunity. Leveraging nucleic acid sensing mechanisms could aid in developing crops with improved disease resistance, which is critical for reducing crop losses and ensuring food security.
