Adsorption (a,c) and desorption (b,d) kinetics of Fe in the root cell wall of tomato plant. The seedlings were exposed to Fe-deficient (1 μM Fe) solution (a,b) or Fe sufficient (50 μM Fe) conditions (c,d) treated with or without 100 μM GSNO for 7 days and then cell wall materials were extracted and analyzed.
