  2. Plant development normally shows plasticity within certain bounds, that is, without falling into extreme phenotypes. The occurrence of multiple receptors and downstream signalling pathways, negative regulators, and positive and negative interactions provides the homeostasis that prevents exaggerated phenotypes under extreme environments. This system leaves room for change because the actual phenotype obtained within the range of normal developmental plasticity can depend on just a few receptors, negative regulators that establish the need for further environmental cues, and interactions that modulate the relationship between signal input and output.
