Penn State Profiles: Reka Albert, Model Researcher
A network-based model of guard cell signaling in plants, created by physicist Reka Albert in collaboration with plant physiologist Sarah Assmann. Drought conditions cause plants to produce the hormone abscisic acid (ABA, top), which triggers guard cells to close leaf pores (bottom), conserving water.
