This study shows that root growth in Arabidopsis depends on glutathione amount, not redox potential, by analyzing mutants with altered GSH levels and redox states.

The paper uses advanced imaging to show photosynthesis affects pH, ATP, and NAD redox in plant cells beyond chloroplasts.

The paper identifies the subcellular localization and biochemical properties of four class I glutaredoxins in Arabidopsis, showing distinct redox activities and membrane associations.

The paper shows that altered iron-sulfur cluster transfer in Arabidopsis mitochondria leads to toxic sulfide release by lipoyl synthase, affecting plant growth and sulfide homeostasis.
