Distributions and dynamics of the signaling molecule in a diffusionless system. Panel A: Distributions of c _A at steady-state for different sets of parameters ($\tilde{\alpha }$, $\tilde{\beta }$) as indicated in Figure 2B. In all cases $\tilde{D}$ = 0. The histogram obtained in simulations (blue bars) compares well with the distribution from the analytical calculations (blue line). Yet, deviations are observed due to intrinsic noise (see text). Panel B: The dynamics of the autoinducer show different behaviors depending on the region of the parameters phase space (see Figure 2). Two typical trajectories are shown with a grey-shaded background indicating the presence of a mRNA molecule in the cell.
