Title
Repression of Floral Meristem Fate Is Crucial in Shaping Tomato Inflorescence

Other claims from this paper (6)
- Observation j mutation suppresses high branching in s and fa mutants.
- Observation J expression is stronger in inflorescence than floral meristems.
- Observation FA activity is higher in floral than inflorescence meristems.
- Observation Loss of J prematurely terminates flower formation and reverts the inflorescence to a vegetative program.
- Observation Absence of SFT enhances the loss-of-J phenotype.
- Mechanism The authors infer that J and an SFT target repress FA activity and floral meristem fate in inflorescence meristems.
