PIF7 overexpression suppresses phyA action under persistent canopy shade, with PIF7 and phyA accumulating together in nuclear photobodies and associating via defined domain interactions.
- Why it matters: Plants need to interpret sustained far-red-rich canopy shade; understanding how phyA High Irradiance Response is tuned in persistent shade addresses a key gap in phytochrome signaling control.
- What they did: The study used PIF7 overexpression and persistent shade conditions, showing nuclear accumulation and association of PIF7 and phyA in photobodies, mediated by PIF7’s C-terminal domain and phyA’s PAS-PAS domain.
- The result: PIF7 also associates with FHY1 and FHY1-LIKE transport facilitators, interfering with phyA cytosolic–nuclear shuttling, which suggests a coordinated mechanism to modulate phyA function in persistent shade.
