  1. BA1 is phosphorylated by BIF2. Both co-localize in the nucleus and both are expressed during axillary meristem initiation. This interaction is important for inflorescence development.
    [PMID: 18466309]
  2. BARREN STALK1 is required for the creation of auxin response maxima at the flanks of the inflorescence meristem.
    [PMID: 18550681]
  3. Genetic and expression analyses suggest that Baf1 is required to reach a threshold level of Ba1 expression for the initiation of maize ears.
