Iron Nutrition and Its Biochemical Interactions in Plants: Iron
Microelements are vital for plant growth and development. Among the micronutrients, iron is required in relatively high concentrations, and although it is one of the most abundant elements in the environment, its availability in soils is restricted due to its low solubility, especially in alkaline conditions and calcareous soils [].In order to cope with its limited …

Iron homeostasis and plant immune responses: Recent insights …
Iron (Fe) is an essential micronutrient for all living organisms, including plants and their associated microbes (1).Iron readily donates and accepts electrons, as it can exist in multiple oxidation states, particularly its ferric (Fe 3+) and ferrous forms (Fe 2+).Therefore, iron cofactors such as heme and Fe-sulfur clusters function in all primary metabolic processes, including …

Current understanding of iron homeostasis
Nonheme iron is abundant in foods of both animal and plant origins and is the dominant form of iron in plants. Nonheme iron is found in a wide variety of forms and includes soluble iron, iron in low–molecular-weight complexes, storage iron in ferritin, and iron in the catalytic centers of a wide range of other proteins.
