SL353/SS555: Iron (Fe) Nutrition of Plants

Root density and extension are very important factors in the plant's ability to obtain Fe. Iron uptake by the plant is not as simple as with other essential elements. Iron is taken up by plant roots in greatest amounts in the zone of the root between cell elongation and maturation, about 1 to 4 cm behind the root tip.

ROLE OF IRON IN PLANT GROWTH AND METABOLISM

which can be used to increase the concentration of iron in rice seeds. The first approach involves enhancing iron accumulation in rice seeds by expressing the ferritin gene under the control of endosperm-specific promoters. The second approach is to increase iron concentrations in rice through overexpression of the nicotianamine synthase gene (NAS).

ROLE OF IRON IN PLANT GROWTH AND METABOLISM

An imbalance between the solubility of iron in soil and the demand for iron by the plant are the primary causes of iron chlorosis. Although abundant in most well-aerated soils, the biological activity of iron is low because it primarily forms highly insoluble ferric compounds at neutral pH levels.

2008-11-21  Abstract. The solubility of iron in soils is controlled by Fe(OH) 3 (soil)in well‐oxidized soils, by Fe3(OH)s(ferrosic hydroxide) in moderately oxidized soils, and by FeCO3(siderite) in highly reduced soils. The Fe(III) hydrolysis species Fe(OH) 2 +, and Fe(OH)3° are the major solution species of inorganic Fe, but they are maintained too low to supply available iron to plants.
