Model illustrating how lowering basal signaling could impact growth and development. When the cell senses changes in extracellular cues, stimulus-induced signaling diverts resources from primary metabolism and may adversely affect normal plant growth (Stress Signal, red). In nonstimulated cells there is a basal flux of metabolism that generates low, oscillating signals (Basal Signal, blue). These basal signals are determined by the genetics and environment of a given organism and fine tune metabolism by repressing or enhancing metabolic events within the cell. If the basal signals are lowered (Lowering the Basal Signal, green), downstream events that were repressed should now be derepressed, and those that were stimulated by the basal signal should decrease. In this manner, lowering the basal signal could enhance growth and development. Whether the plants with lower basal signaling would be more or less tolerant of stress would depend on whether the second messenger was necessary for stress tolerance and whether compensatory tolerance pathways were induced.
