WebTo ensure iron acquisition from soil and to avoid iron excess in the cells, uptake and homeostasis are tightly controlled. Plants meet the extreme insolubility of oxidized iron at neutral pH values by deficiency-inducible chelation and reduction systems at the root surface that facilitate uptake. WebJun 25, 2024 · In general, a soil pH in the range of 7.4–8.5 caused a low solubility and slow dissolution kinetics of iron-bearing minerals. Also elevated bicarbonate concentrations, typical of calcareous soils, reduce the iron acquisition by plants grown on alkaline soils.
WebSep 16, 2024 · iron homeostasis in plants is vital, as it is not only relevant to fundamental biological questions, but also to agriculture, biofortification, and human health. WebOxidative status of plant cells is directly affected by the modulation of iron homeostasis. Among mammals and plants, heme oxygenase-1 (HO-1) is a well-known antioxidant enzyme. It catalyzes oxygenation of heme, thereby producing Fe2+, CO and biliverdin as byproducts.
