The fluorescent protein sensor roGFP2‐Orp1 monitors in vivo H2O2 and thiol redox integration and elucidates intracellular H2O2 dynamics during elicitor‐induced oxidative burst in Arabidopsis

Abstract:

Hydrogen peroxide (H2O2) is ubiquitous in cells and at the centre of developmental programmes and environmental responses. Its chemistry in cells makes H2O2 notoriously hard to detect dynamically, specifically and at high resolution. Genetically encoded sensors overcome persistent shortcomings, but pH sensitivity, silencing of expression and a limited concept of sensor behaviour in vivo have hampered meaningful H2O2 sensing in living plants. We establish H2O2 monitoring in the cytosol and th...
