CC   -!- FUNCTION: Probable transcription factor that promotes early floral
CC       meristem identity in synergy with APETALA1 and CAULIFLOWER. Is required
CC       subsequently for the transition of an inflorescence meristem into a
CC       floral meristem (PubMed:28586421). Seems to be partially redundant to
CC       the function of APETALA1 and CAULIFLOWER in the up-regulation of LEAFY.
CC       Is also required for normal pattern of cell division, expansion and
CC       differentiation during morphogenesis of the silique (PubMed:28586421).
CC       Probably not required for fruit elongation but instead is required to
CC       prevent ectopic activity of IND. Represses SAUR10 expression in stems
CC       and inflorescence branches (PubMed:28586421).

CC   -!- INDUCTION: Dramatically up-regulated upon the transition from
CC       vegetative to reproductive development.
CC   -!- DISRUPTION PHENOTYPE: Altered cauline leaf shape, abnormal stem
CC       development and architecture, including enhanced branching, decreased
CC       inflorescence branch angles, and shorter stem and internode lengths.
CC       Reduced stems elongation after bolting. {ECO:0000269|PubMed:28586421}.
