Unraveling uranium induced oxidative stress related responses in Arabidopsis thaliana seedlings. Part II: responses in the leaves and general conclusions

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