JrTTG2 is a hypersensitive early-response WRKY transcription factor in walnut roots, showing a 333-fold induction under drought and coordinating antioxidant and trafficking-linked responses.
- Why it matters: Drought limits Juglans regia productivity, but the regulatory circuitry that enables woody plants to tolerate water deficit remains unclear.
- What they did: The study mapped transcriptional and protein-interaction networks, then tested function by ectopically expressing JrTTG2 in Arabidopsis and poplar and silencing PagTTG2 in poplar; it also used promoter binding, transcriptomics, yeast two-hybrid, and BiFC to link JrTTG2 to JrGSTU8 and JrEPSIN1.
- The result: JrTTG2 directly activates JrGSTU8 via a W-box to enhance ROS scavenging, and it physically interacts with JrEPSIN1; together these synchronized drought-induced modules help maintain root architecture, biomass, and antioxidant defense.
