Cross-Talk in Abscisic Acid Signaling

Nina V. Fedoroff*

Gloss: Abscisic acid (ABA) is a plant hormone that regulates such processes as seed and bud dormancy and the senescence (aging) and abscission (dropping off) of leaves. It is also important for a plant's ability to respond rapidly to water loss by closing leaf stomata (pores), as well as to other stressful environmental conditions. In this review, Federoff summarizes what is known about how ABA signals are perceived and transmitted within a plant. Federoff then discusses how the ABA signaling system is interconnected with signaling systems in plants that use sugars, and other hormones, such as ethylene and auxin. Interconnections or "cross-talk" between signaling systems allows the plant to integrate information from a variety of sources and adjust appropriately to ambient conditions.
