Medchemexpress LLC N-Hydroxypipecolic acid | 115819-92-6 | 1 ML
N-Hydroxypipecolic acid is a plant metabolite and a systemic acquired resistance (SAR) regulator. It works in conjunction with the immune signal salicylic acid to establish SAR. This compound accumulates systemically in plant foliage following a pathogen attack and induces SAR against bacterial and oomycete infections. Its mode of action involves directly inducing SAR gene expression, amplifying signals, priming for enhanced defense activation, and positively interacting with salicylic acid signaling to boost plant immunity.
