ABSTRACT
Nitroxyl (HNO) is the one-electron reduced and protonated congener of nitric oxide (â¢NO), owning a distinct chemical profile. Based on real-time detection, we demonstrate that HNO is endogenously formed in Arabidopsis. Senescence and hypoxia induce shifts in the redox balance, triggering HNO decay or formation mediated by non-enzymatic â¢NO/HNO interconversion with cellular reductants. The stimuli-dependent HNO generation supports or competes with â¢NO signalling, depending on the local redox environment.
