Plants activate systemic acquired resistance (SAR), a form of long-lasting induced defense, to confer protection against a broad spectrum of pathogen. The induction of SAR requires the accumulation of salicylic acid (SA) and a subset of the pathogenesis-related (PR) genes in both local and systemic tissues. To clarify the SAR signaling pathway using chemical biology technique, we have established a high-throughput system for the easy identification of chemicals affecting SAR. We identified one candidate chemical, 4-phenyl-2-{[3-(trifluoromethyl)anilino]methylidene}cyclohexane-1,3-dione (PAMD), that down-regulates the expression of pathogenesis-related (PR) gene.
