Interactions among some of the hormonal and environmental signals and regulatory elements controlling the transition from dormancy to germination.

ABA receptors listed are those that are most abundantly expressed in dry and imbibing seeds. Red triangles represent ABA accumulation during either dormancy maintenance or in response to dehydrating stresses following dormancy release. Arrows indicate positive regulation and red bars represent repression, illustrating substantial cross-talk controlling ABA/GA balance and feedback within each hormone's signaling network.
