Interactions between H2O2 and glutathione in gene expression
ABSTRACT: rs08-03_glutathion - glutathion - How does glutathione content or reduction state affect H2O2-induced changes in the transcriptome? - Three single Arabidopsis mutants were used: cat2, knockout for catalase2 and so enriched in H2O2; cad2, defective in glutathione content; cytGR, knockout for cytosolic glutathione reductase. Cat2 was crossed with cad2 and cyt GR, and col0, 3 single mutants, and 2 double mutants were sampled in controlled growth conditions either in 8h or 16h photoperiod. Keywords: gene knock out 20 dye-swap pairs - CATMA arrays: 40 arrays
Arabidopsis GLUTATHIONE REDUCTASE1 plays a crucial role in leaf responses to intracellular hydrogen peroxide and in ensuring appropriate gene expression through both salicylic acid and jasmonic acid signaling pathways.
Glutathione is a major cellular thiol that is maintained in the reduced state by glutathione reductase (GR), which is encoded by two genes in Arabidopsis (Arabidopsis thaliana; GR1 and GR2). This study addressed the role of GR1 in hydrogen peroxide (H(2)O(2)) responses through a combined genetic, transcriptomic, and redox profiling approach. To identify the potential role of changes in glutathione status in H(2)O(2) signaling, gr1 mutants, which show a constitutive increase in oxidized glutathio ...[more]
