Other claims from this paper (13)
- Observation The f mutation nearly completely inhibits leaf axillary buds.
- Observation The f mutation restricts floral induction.
- Observation Immediately after seed imbibition, the mutant meristem was enlarged.
- Observation The mutation hastened differentiation of the second trifoliolate leaf primordium after seed imbibition.
- Mechanism The early phenotype suggests f functions upstream of other developmental genes.
- Observation Mutant leaf arrangement changed from wild-type distichous to decussate and later semiwhorled.
- Observation The mutant meristem enlarged continuously and had a shorter plastochron.
- Observation The dome-shaped meristem persisted for 11-12 plastochrons and reached four to five times wild-type size.
- Observation Meristem zonation accompanied a progression from rectangular through round, triangular, and oval to ridgelike form.
- Mechanism The stable ridgelike meristem may reflect a new balance of cell division and differentiation.
- Observation Endogenous IAA was two- to threefold higher in meristematic tissues, hypocotyl, and leaves than in wild type.
- Mechanism Auxin overproduction by the proliferating meristem could explain elevated IAA.
- Mechanism The f gene product might affect cell divisions and auxin metabolism.
