Other claims from this paper (11)
- Observation Flowering-dependent hypocotyl xylem expansion occurs generally in rosette herbaceous plants.
- Intervention effect Flowering induction triggered Arabidopsis xylem expansion.
- Observation Flower formation was not required for xylem expansion.
- Observation Main inflorescence elongation was not required for xylem expansion.
- Observation Xylem expansion did not depend on a particular flowering time pathway.
- Mechanism ERECTA locally restricted xylem expansion downstream of GA.
- Mechanism GA and its signaling pathway were necessary for enhanced xylogenesis.
- Mechanism GA and its signaling pathway were sufficient for enhanced xylogenesis.
- Intervention effect Impaired GA signaling did not affect xylem expansion systemically.
- Observation The GA effect was graft transmissible.
- Mechanism Authors infer that GA itself is the mobile shoot-derived signal.
