Phenomena and Processes

Plant Systemic Acquired Resistance

A plant defense mechanism in which a plant pathogen-associated molecular pattern effector is detected through various receptors, e.g., PATTERN RECOGNITION RECEPTORS, which in turn induces fortified, primed defense in plant immune reaction. It confers long lasting and long distance plant immune defense against a broad spectrum of pathogens using various plant defense hormones or metabolites, e.g., SALICYLIC ACID and N-HYDROXYPIPECOLIC ACID, as signals to distant leaves for heightened immune state to counteract and limit subsequent infection.
