FIGURE 10

Effect of Fe deficiency and foliar application of Fe on GSNO content in roots of Arabidopsis WT Columbia and opt3-2 mutant plants. Plants were grown in nutrient solution with Fe (+Fe). Some of them were transferred to nutrient solution without Fe 2 days before harvest (–Fe). Half of the –Fe plants were sprayed with Fe 24 h before harvest (–Fe+fol Fe). Data represent the mean ± SE of six replicates. Within each genotype, bars with different letters indicate significant differences (P < 0.05). Significant difference between the +Fe treatment from opt3-2 and Col is also indicated: ∗∗P < 0.05.
