SUMMARY
Iron (Fe) is an important micronutrient for plant growth and it has several functions. A large portion of agricultural soils around the world has low Fe-availability to plants due to its unavailable forms or varying nature of soils including calcareous soils. The deficiency of Fe led to adverse effects on plant growth and agricultural productivity. It has got recent attention and molecular, biochemical, physiological responses of plants under Fe deficiency is being reported in some crops. To understand the mechanism of Fe deficiency tolerance, this review provides an overview of such studies.
Key words: Fe-deficiency, calcareous soils, phytosiderophores, Superoxide dismutase
