Functional Characteristics
Salicylic acid is a metabolite of phenylalanine and a novel natural phenolic plant regulator; it serves as a crucial endogenous signaling molecule that activates plant hypersensitive responses and systemic acquired resistance. Within the plant, it plays a wide range of physiological roles, including regulating processes such as growth, development, maturation, and senescence, as well as inducing stress-response mechanisms against salinity, drought, low temperatures, ultraviolet radiation, and heavy metals.
