During the initial stages of flower development, floral meristems increase in size without the formation of
floral organs. When a critical meristem size is reached, the floral meristem begins to develop the floral
organs. The first stages of flower development are characterized by the expression of genes such as
APETALA 1 (AP1), CAULIFLOWER (CAL), AGAMOUS-LIKE 24 (AGL24) and SHORT VEGETATIVE PHASE (SVP).
We have shown that AP1, AGL24 and SVP act redundantly to control the identity of the floral meristem and
to repress expression of class B, C and E genes. Recently, it was shown that class E gene repression was
direct and established by two independent pathways
