Thiol-based redox homeostasis and signaling Cejudo, Francisco J. Meyer, Andreas J. Reichheld, Jean-Philippe Rouhier, Nicolas Traverso Gutiérrez, José Ángel Thioredoxin Glutaredoxin Glutathione Redox regulation Redox signaling Plants Plants imperatively have to cope with adverse conditions owing to their lack of mobility and to the high amounts of reactive oxygen species (ROS) generated from both respiration and photosynthetic metabolism. Although thiol redox homeostasis in plants is mainly preserved by the cellular glutathione pool, specific strategies have been adopted by the plant kingdom during evolution to manage these “extra” pro-oxidative conditions. Unlike human or yeast, plants generally possess a higher number of genes coding for antioxidant proteins, including protein families responsible of dithiol/disulfide exchange reactions. During the last decades, redox-dependent post-translational modifications of proteins proved to be pivotal to many cellular functions. In particular, this is critically important under some situations of environmental constraints taking into account the alterations and fine adjustment of the cellular redox status occurring during and after any biotic or abiotic stresses. 2014-09-02T11:24:17Z 2014-09-02T11:24:17Z 2014-06-10 info:eu-repo/semantics/article Cejudo, F.J.; et al.
