Abstract
⺠Unravel response mechanisms to uranium stress in Arabidopsis thaliana roots. ⺠Oxidative stress related responses only present at 100 μM uranium. ⺠SOD constitutes first line of defense against O2â. ⺠H2O2 is postulated as signaling molecule. ⺠Controlling H2O2 levels by APX seems to be important. ⺠Regeneration of oxidized ascorbate by glutathione is hampered.
