Plant biology: Abscisic acid in bloom

Julian I. Schroeder1 & Josef M Kuhn1

Top

To survive environmental stresses, plants must respond to the hormone abscisic acid. The receptors for this hormone have remained elusive, but one receptor with unique functions in flowering has now been identified.

When plants experience drought or cold, they cannot get themselves a glass of water or move to a warmer place. Instead, their ability to survive lack of water, extreme temperatures and such stresses as high salt levels relies heavily on a plant hormone called abscisic acid (ABA).
