Figure 6
Main subsystems for the segment polarity network model. Diagrams representing the 5 main subsystems for the model (S A , SB 1, SB 2, SC 1, SC 2). Each diagram shows the nodes, states (white = 1, black = 0) and cells involved in the subsystem. Interactions between the nodes are also shown (red arrow = activation, blue dot = inhibition, dashed line = indirect interaction). All subsystems are fixed states. There are 14 other minor subsystems for this model (SD 1- SJ 2), which are shown in Table 5.
