Research team rewriting book on photosynthesis
July 14, 2005

PULLMAN — Toss out that old biology book you were hanging onto for reference. The chapter on photosynthesis is about to be rewritten, thanks to work by David Kramer and his research team at Washington State University’s Institute of Biological Chemistry.Using instruments they designed and built themselves, Kramer and his group have discovered that plants adjust their light intake to match their metabolic needs by regulating the level of protons within sealed chambers in the chloroplasts.Traditionally, plant physiologists have focused on the role of electrons in photosynthesis. Kramer’s lab has changed the field by looking at what’s happening with the protons inside chloroplasts in intact … » More …
