TL;DR: How alterations in glutathione status, such as those observed during stress, may participate in signal transduction cascades are discussed and how these alterations are integrated to fine-tune photorespiratory and respiratory metabolism and to modulate phytohormone signalling pathways.

TL;DR: This review provides an update on plant catalase genes, function, and subcellular localization, with a focus on recent information generated from studies on Arabidopsis.

TL;DR: It is concluded that GR1 plays a crucial role in daylength-dependent redox signaling and that this function cannot be replaced by the second Arabidopsis GR gene or by thiol systems such as the thioredoxin system.

TL;DR: In parallel to its antioxidant role, GSH acts independently of NPR1 to allow increased intracellular H(2)O( 2) to activate SA signaling, a key defense response in plants.

TL;DR: Lesion formation triggered by peroxisomal H2O2 was modified by introducing secondary mutations into the cat2 background and was completely absent in cat2 sid2 double mutants, in which ISOCHORISMATE SYNTHASE1 (ICS1) activity is defective.
