  1. The first five columns indicate the input signal combination. The setting CO2_high = 1 and CO2 = 0 is not included because it is not biologically meaningful. The “SO (Bool)” column indicates the state of the Boolean node combination representing stomatal opening. The “SO” column is the state of stomatal opening when converted back to an integer. Note that the stomatal opening level of four is not defined, and no attractors have a stomatal opening level of two. The next column indicates whether Ca2+ oscillation can possibly happen under the given signal combination. The last column indicates whether bistability of PMV_pos can be observed under this setting. In those cases, two stable steady states with (PMV_pos = 0, Kout = 0) and (PMV_pos = 1, Kout = 1) can be observed. The rest of the nodes are unaffected by this two-node bistability
