Figure 3From: Identifying dynamical modules from genetic regulatory systems: applications to the segment polarity networkPartition sequences in the example Boolean network model. (A) 10 partition sequences are identified for the example model in Fig. 2. Each column in each sequence corresponds to a node in the model, whilst each row corresponds to a partial state. White/Black corresponds to the node having state 1/0 in the partial state. Eight of these (P3 – P10) are also intersection sequences, whilst the remaining two (P1 and P2, starred) are core sequences that underlie multiple intersection sequences (see Tables 1 and 2). (B, C) Examples of hierarchy amongst the sequences in A. In each case, node i corresponds to the partial state sequence P i . In each case, if a link joins a partial state sequence P x (top) to another P y (bottom), P x occurs in P y and is conserved across a greater number of attractors. (B) Hierarchy between intersection sequences. (C) Hierarchy between partition sequences. Orange nodes correspond to sequences with sub-dynamics that are distinct from those in sequences further up the hierarchy. These 6 distinct sub-dynamics are the subsystems (see Table 3). White nodes correspond to sequences that are just a combination of sequences further up the hierarchy.Back to article page
