Other claims from this paper (8)
- Intervention effect Low red to far-red light induced petiole elongation and leaf hyponasty.
- Intervention effect Green shade induced petiole elongation and leaf hyponasty.
- Intervention effect Green shade caused rapid proton efflux into the petiole apoplast relative to white light.
- Mechanism Apoplastic acidification may support optimal activity of cell wall modifying proteins.
- Intervention effect Acid-induced extension, expansin susceptibility and extractable expansin activity were similar under white light and shade.
- Intervention effect Shade treatments produced high XTH activity in petioles.
- Intervention effect Green shade significantly upregulated XTH15, XTH16, XTH17, XTH19 and XTH22.
- Observation Two XTH knockout mutants had reduced or absent shade avoidance responses.
