FFL function and their probabilities. (a) The landscape of FFL motifs is displayed as a bipartite graph linking patterns (upper row) and processes (lower). The weight of the links indicates the relative probability P(ϕ j | Γ i ) that a given motif Γ i implements a given function ϕ j . In (b) the matrix of motif-function probabilities is displayed using a color scale. The plots highlight that some motifs look more specialized, whereas others display rather evenly distributed functional responses.
