Other claims from this paper (4)
- Intervention effect Root-tip removal caused a rapid but transient increase in lateral primordia, greatest in the apical root segment.
- Mechanism One or more lateral-root promoters also appear to be produced in the epicotyl.
- Mechanism The root tip may supply a basipetally moving substance that interacts with promoters to regulate the initiation zone.
- Mechanism The root tip appears to supply a strong inhibitor of lateral-root emergence.
