Sulfonamides Inhibit Root Growth via ROS-Triggered and MPK3/6-Modulated Synthesis of the Ethylene Precursor ACC

Sulfonamide antibiotics threaten ecosystems, yet their phytotoxic mechanisms remain elusive. Here, we demonstrate that sulfonamides inhibit root growth by disrupting the ROS-ethylene signaling axis. Sulfadiazine (SD) strongly inhibits root elongation, an effect strictly dependent...
