In this study, the rhizosphere environment was simulated by adding CA to water and soil. Additionally, the experiment results indicated a plausible explanation for the phenomenon of zero-valent iron nanomaterials promoting both Cd stabilization in soil and plant uptake. In addition, the role of CA and the microorganisms was also investigated.
Iron uptake strategies in plants, not so different after all. (a) Strategy I, also called the reduction-based strategy, was first described as specific to non-grass species.In Arabidopsis, AHA2 (H +-ATPase) secretes protons into the rhizosphere to solubilise Fe 3+ which is then reduced into Fe 2+ by the ferric reductase FRO2. Fe 2+ is then uptaken …
Iron is necessary for the growth and development of plant because it plays a crucial role in the activity of enzymes, transcription of DNA, and synthesis of RNA, enhance the photosynthesis rate as it improves the photosystem and increase the activity of auxin [].]. Due to the cheap and low toxic effect of iron-based NPs fertilizers considered to be …
Plant tolerance to elevated Fe is enhanced by effective regulation of primary Fe transport at the root plasma-membrane level and of Fe distribution at the subcellular, cellular, and tissue/organ levels (Engel et al., 2012).The distribution of Fe in different parts of plant tissues has been well outlined in the past (see review by Becker and Asch, …

Plant Sci., 2017, 8, 40 Search PubMed. H. H. Tsai and W. Schmidt, Mobilization of iron by plant-borne coumarins, Trends Plant Sci., 2017, 22, 538–548 CrossRef CAS PubMed.
This occurs due to the accumulation of iron ions in the plant tissues, leading to oxidative damage. Additionally, excessive iron can interfere with the uptake of other essential nutrients, causing nutrient imbalances and further impacting plant health. ... The pH level of the soil plays a crucial role in iron availability to plants. Adjusting ...
This is because heme iron from meat is more bioavailable than nonheme iron from plant-based foods, and meat, poultry, and seafood increase the absorption of nonheme iron . ... This section focuses on the role of iron in IDA in pregnant women, infants, and toddlers as well as in anemia of chronic disease.
Another role of iron is as a cofactor for enzymes involved in energy metabolism, DNA and amino acid synthesis, hormone synthesis, and immune function. ... Non-heme iron, found in plant sources such as beans, nuts, dark chocolate, legumes, spinach, and fortified grains, has about two-thirds the bioavailability of heme iron. About …
Iron is an essential element for all living organisms, playing a major role in plant biochemistry as a redox catalyst based on iron redox properties. Iron is the fourth most abundant element of the Earth's crust, but its uptake by plants is complex because it...
Organic matter in soils plays a major role in the availability of Fe to plants. Biochemical compounds or organic acids (aliphatic acids or amino acids) ... manifest first in the older leaves because N can be mobilized from the older leaves to satisfy the needs in the upper plant. Iron deficiency in turfgrass is typically in spots or patches ...
