Figure 2:
Analysis of the condition for the cooperativity between two competing modules. (A) Diagram of the two features to quantify the cooperative behavior. The maximum relative increment (MRI) is the maximum relative change between the expression level of module 2 with and without module 1 expression. The competition relief range (CRR)represents the range of x1ss where the module 2 expression is enhanced by expressing module 1. (B) The dependence of MRI (left) and CRR (right) on J with fixed (Q = 75.14). Colormaps of MRI (C) and CRR (D) in the space of Q and J. Red lines represent the parameter condition (see the inequality equation 3).
