Effect of exogenous GSNO treatment on Fe content in root cell wall components.
The seedlings were treated with or without 100 μM GSNO for 7 days under Fe deficient conditions (1 μM Fe) or Fe sufficient conditions (50 μM Fe) and then roots were harvested and cell wall extraction and fraction for Fe contents analyzed. Fe content in cell wall (a) Fe content in pectin (b) Fe content in HC1 (c) and Fe content in HC2 (d) Error bars represent ± SD (n = 4). Bars with different letters are significantly different at P < 0.05.
