Other claims from this paper (8)
- Observation Juvenile and adult regions of transition leaves did not become clonally distinct until primordia exceeded 700 microm.
- Intervention effect In vitro culture at least partly rejuvenated leaf primordia as large as 3 mm.
- Association The location of rejuvenated tissue correlated with the maturation pattern of the leaf.
- Mechanism The juvenile-tissue pattern suggested near-simultaneous rejuvenation across leaf primordia.
- Intervention effect In vitro culture rejuvenated existing leaf primordia and P0 primordium.
- Intervention effect In vitro culture did not change subsequent primordia identity.
- Mechanism Leaf identity can be regulated independently of shoot apical meristem identity.
- Mechanism Vegetative phase change was inferred not to start with a change in shoot apical meristem identity.
