SALICYLIC ACID SENSOR1 reveals the propagation of an SA hormone surge during plant pathogen advance
Salicylic acid (SA) is a key phytohormone that orchestrates immune responses against pathogens, including Pseudomonas syringae bacteria. The timing and extent of SA accumulation are tightly controlled...
