Antioxidant response system in the short-term post-wounding effect in Mesembryanthemum crystallinum leaves
Mechanical wounding of Mesembryanthemum crystallinum leaves in planta induced a fast decrease in stomatal conductance, which was related to accumulation of hydrogen peroxide (H 2O 2). Higher levels of H 2O 2 were accompanied by an increase in total activity of superoxide dismutase (SOD) and a decrea...

Mesembryanthemum crystallinum leaves
in planta induced a fast decrease in stomatal conductance, which was related to accumulation of hydrogen peroxide (H
2O
2). Higher levels of H
2O
2 were accompanied by an increase in total activity of superoxide dismutase (SOD) and a decrease in catalase (CAT) activity. Among SOD forms, manganese SOD (MnSOD) and copper/zinc SOD (Cu/ZnSOD) seem to be especially important sources of H
2O
2 at early stages of wounding response. Moreover, NADP-malic enzyme (NADP-ME), one of the key enzymes of primary carbon metabolism, which is also involved in stress responses, showed a strong increase in activity in wounded leaves. All these symptoms: high accumulation of H
2O
2, high activities of Cu/ZnSOD and NADP-ME, together with the decrease of CAT activity, were also observed in the major veins of unwounded leaves. The potential role of veinal tissues as an important source of H
2O
2 during wounding response is discussed. |
