Effect of NO on the cell wall compositions in tomato roots.
The seedlings were treated with or without 100 μM GSNO for 7 days under Fe deficient condition (1 μM Fe) or Fe sufficient condition (50 μM Fe) and roots were sampled and cell wall polysaccharides were fractionated into pectin, HC1, HC2 for uronic acid content measurement. Error bars represent ± SD (n = 4). Bars with different letters are significantly different at P < 0.05.
