Only a positive interaction on bHLH genes or a negative one on CPC (rows in grey) produces an increase in trichome density and maintains the spaced-out pattern. The sign of interaction is in parentheses. Asterisks indicate an interaction probability P_GA< 1, while no asterisk means that this probability was equal to one. The two cases P_GA= 1 and P_GA< 1 are only shown when their results are different. These simulations were performed in 20 × 20 matrices with the following parameter values: D_CPC= 0.05, D_TRR= 0.05, D_TTG= 0.03.
