Iron （Fe） is an essential metal nutrient for plant productivity and plant product quality （Briat et al., 2015）. Fe exists under two forms, ferrous （Fe^2＋） or ferric （Fe^3＋）, and is very reactive with oxygen, explaining why Fe plant nutrition is dependent upon both Fe chelation and Fe reduction. Fe availability in the soil is pH dependent, this metal being particularly insoluble in its ferric form in calcareous soils, representing one-third of the world＇s cultivated soils. Consequently, plants grown on these soils, in particular non-graminaceous plants, often suffer from Fe deficiency, which alters their growth.
