Plant immunity refers to the mechanisms and processes by which plants detect and respond to pathogens, pests, and other harmful agents. Unlike animals, plants lack specialized immune cells and instead rely on innate immune responses that occur at the cellular level. Plant immunity is crucial for survival, influencing plant health, productivity, and resilience in natural and agricultural ecosystems.
Key Components of Plant Immunity :
Physical and Chemical Barriers:
Innate Immune Responses:
Mechanisms of Plant Defense :
Physical Barriers and Structural Defenses:
Chemical Defenses:
Applications of Plant Immunity :
Plant immunity is a sophisticated and dynamic system that enables plants to defend themselves against a wide range of threats. Advances in our understanding of plant immune mechanisms offer promising avenues for improving crop protection, sustainability, and food security in the face of increasing global challenges.
