LFY and AP1/CAL act as part of an incoherent feed-forward loop, a network motif where two interconnected pathways or transcription factors act in opposite directions on a target gene, to control the establishment of a stable developmental program for the formation of flowers.
Title: Transcription Factor Interplay between LEAFY and APETALA1/CAULIFLOWER during Floral Initiation.

the differences between the Arabidopsis (Arabidopsis thaliana) APETALA1 (AP1) and CAULIFLOWER (CAL) duplicate genes in the time, space, and level of expression were determined by the presence or absence of functionally important transcription factor-binding sites (TFBSs) in regulatory regions.
Title: Gains and Losses of Cis-regulatory Elements Led to Divergence of the Arabidopsis APETALA1 and CAULIFLOWER Duplicate Genes in the Time, Space, and Level of Expression and Regulation of One Paralog by the Other.

Expression of the transcription factor CAL is activated by LFY and the meristem identity regulator LMI1.
Title: The LEAFY target LMI1 is a meristem identity regulator and acts together with LEAFY to regulate expression of CAULIFLOWER.

The unique and redundant functions of the APETALA1 and CAULIFLOWER genes have been mapped to the four protein domains that characterize type-II MADS-domain proteins.
