Succession diagram for Model1 with short term memory. (A) Stable motif succession diagram in the absence of ABA and any other closure-inducing signal. Regardless of the duration of the memory, this case always leads to an open stomata attractor. (B) Motif succession diagram in the presence of ABA. The system can reach two different attractors depending on whether the memory duration is large enough. When the memory duration is large enough, sustained Ca²⁺_c oscillations can sustain the ON state of the nodes CPK3/21, MPK9/12, Microtubule Depolymerization, and Vacuolar Acidification. With small memory duration these nodes oscillate instead of stabilizing; as a result, the node corresponding to stomatal closure also oscillates. See Supplementary Text S3 for details on the sufficient memory durations and Supplementary Table S4 for these attractors. The dashed edges denote logic succession with certainty while the dotted edges denote the variant outcomes depending on the memory duration.
