Abstract

Plant cells sense, weigh and integrate various endogenous and exogenous cues in order to optimize acclimation and resource allocation. The thiol/disulfide redox network appears to be in the core of this versatile integration process. In plant cells its complexity exceeds by far that of other organisms. Recent research has elucidated the multiplicity of the diversified input elements, transmitters (thioredoxin, glutaredoxins), targets and sensors (peroxiredoxins and other peroxidases), controlled processes and final acceptors (reactive oxygen species). An additional level of thiol/disulfide regulation is achieved by introducing dynamics in time and subcompartment and complex association.
