Plant Immunity Signaling

Plant immunity signaling refers to the complex network of pathways that plants use to detect and respond to pathogens. This signaling involves recognition of pathogen-associated molecular patterns (PAMPs) and effector molecules through receptor proteins, triggering defense responses such as hypersensitive cell death, production of antimicrobial compounds, and activation of systemic acquired resistance. Key components of these signaling pathways include phytohormones like salicylic acid, jasmonic acid, and ethylene, which coordinate various defense responses. Understanding plant immunity signaling is essential for developing crops with enhanced disease resistance and for creating strategies to improve agricultural resilience against biotic stressors.
