Lessons from Redox Signaling in Plants
CHRISTINE H. FOYERl and JOHN F. ALLEN2
ALL LIV ING ORGANISMS are oxidation-reduction (redox)
systems. They use anabolic, reductive processes to
store energy and catabolic, oxidative processes to release it. It
is plants that set this global wheel in motion. By harnessing
light energy to drive biochemistry, photosynthetic organ isms
have perfected the art of redox contro !' Indeed, it is now
widely accepted that redox signals are key regulators of plant
metabolism, morphology, and development. These signals
exert control on nearly every aspect of plant biology from
chemistry to development, growth, and eventual death. It is
therefo re timely and appropriate that the current state of sci-
entific advancement is assessed and reviewed in this volume.
We suggest that "redox signaling" was the first type of sen-
