Abstract excerpt
The root apical meristem activity and hence plant growth strictly depend on glutathione homeostasis. Despite compelling evidence for this dependency based on glutathione depletion, the cause for the growth arrest had remained unclear. Meristem control may depend on either the absolute amount of glutathione or its redox potential (EGSH). To unambiguously distinguish those two options, we characterized an allelic...
