Main subsystems for the segment polarity network model. Diagrams representing the 5 main subsystems for the model (SA, SB1, SB2, SC1, SC2). 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 (SD1 - SJ2), which are shown in Table 5.
