Abstract

âº Unraveling oxidative stress related responses in A. thaliana leaves following uranium exposure. âº A root-to-shoot signaling system was suggested. âº Both ROS and LOX initiated lipid peroxidation. âº A transient character of uranium stress responses in leaves. âº Ascorbate redox balance seemed an important modulator of uranium stress in leaves.
