A PIF4-PUB9-DSK2A signaling loop integrates skotomorphogenesis and carbon starvation response in Arabidopsis.

When seeds germinate under soil, the emerging seedlings undergo a period of darkness. Short-term darkness promotes skotomorphogenesis, whereas prolonged darkness leads to carbon starvation, triggering a transition from growth to autophagy-mediated survival. The molecular mechanism by which plants coordinate skotomorpho...
