Schematic representation of the FFL motif and its functions. Schematic representation of the FFL motif and its functions. In (a) the genetic organization is shown. Activation signal X regulates the expression of gene G Y , whereas gene G Z is regulated in joined mode by gene product Y and X. This small system can be formally represented in a graph (b) with a given topology and a set of dynamical equations describing the kinetics of its regulatory interactions. For a given set of parameters, a specific type of response (c) might be observed. In (d) all possible regulatory combinations are shown.
