The FT-GRN underlying signal sensing and integration drives the developmental trajectories from the vegetative to the reproductive stage of development. (A) Turning “ON” the input nodes can drive the system from one phenotype to another, recovering the temporal sequence of differentiation in response to environmental (VER), endogenous (AGE and FCA), and spatial (PNY) signals. Differentiation simulations for (B) SD and (C) LD photoperiods, the VER and AGE nodes drive the temporal progression from JVM to AVM; while upregulation of FCA drive the system from the AVM to the IM stage and increasing PNY drives the IM to the FM state.
