XAL2 is an important component of the FT-GRN that mediates GA promoting flowering response in SD. We performed mutant simulations in SD with or without GA treatment, fixing the FT-GRN model to simulate SD by keeping the CO input turned off, and GA exogenous treatment was simulated by keeping the GA node turned on. Wild-type, xal2, and spl9 single and double mutants were simulated with (lower panel) or without GA (control, upper panel). For each mutant background under a specific “growth” condition we calculated their attractors, classified them in meristem phenotypes (JVM, AVM, IM, FM, and “Other” which were vegetative cyclic attractors), and plotted their relative basin size as a percentage of all the initial state space.
