Summary: Iron is an essential micronutrient for plant growth, but its bioavailability can be limited in calcareous soils, leading to iron deficiency in plants. Currently, iron fertilization is commonly used in agriculture to prevent or treat iron deficiency chlorosis. Fe-fertilizers based on synthetic ligands effectively maintain iron in the soil solution and increase its bioavailability for plant uptake. However, these complexes have limitations such as pH-dependent effectiveness and environmental persistence. Plant-derived protein hydrolysates have the potential to be used as biochelating ligands in innovative iron fertilizers. Experimental trials on horticultural crops have shown that Fe-biochelate is as efficient as traditional synthetic chelates, even under alkaline conditions. This finding suggests that Fe-biochelates could be promising alternatives for iron nutrition management in crops.

Summary: This study compared the effects of four iron fertilizers on soybean growth, with FeHBED and FeEDDHA-1 showing similar and positive results, while FeEDDHA-2 and FeEDDHSA exhibited weaker effects. The effectiveness of these fertilizers in increasing dry matter or iron uptake was predicted by a simple laboratory test measuring the solubility of applied iron in soil after incubation.

Summary: This study demonstrates that nitric oxide (NO) plays a crucial role in restoring iron (Fe) deficiency-induced growth inhibition and oxidative stress in alfalfa. By upregulating specific genes, NO helps alleviate the negative effects of Fe deficiency by inhibiting oxidative stress and enhancing antioxidant defense mechanisms.

Summary: Iron plays a vital role in the metabolism of cancer cells, targeting tumors through the ferroptotic death pathway. In addition to iron, ligands also impact the biological activity of iron complexes. Research indicates that the stability of iron complexes is crucial for their anticancer properties.

Summary: This study examines the susceptibility and reaction of calcifuge plant species in dry acidic grasslands to pH-dependent iron (Fe) starvation. It finds that some plants are sensitive to pH-dependent chlorosis, and this deficiency can be reduced by Fe supplementation. The preference for acidic soil varies among different plants, and Fe-HBED treatments in alkaline soil may not support growth as effectively as in acidic soil. Overall, calcifuge plant species from dry acidic grasslands have diverse susceptibility to Fe-dependent chlorosis and different Fe requirements and acquisition strategies.

Summary: Iron deficiency leads to leaf chlorosis in Areca catechu L. trees, while excessive iron supply results in dark green leaves. Both excessive and deficient iron levels decrease fresh weight and photosynthetic rate in seedlings of A. catechu.

Summary: Iron humate participates in the chelate shuttle mechanism, providing available Fe to the chelating agent and then to the plants, showing a slight synergic effect. After a few days, the contribution of the chelates to the Fe nutrition decreases substantially, but the contribution of the humates is maintained. The most efficient ratio was two parts of iron humates and one part of iron chelate. Specifically, HBED/Fe3+ was the most suitable iron chelate because its lasting effect fits the iron humate long-term effect better.

Summary: Zinc (Zn) and iron (Fe) are essential micronutrients for all living organisms and major targets for crop biofortification. Excess Zn can induce Fe deficiency symptoms in soybean plants, while Fe accumulation is not greatly affected by elevated Zn supplies. The interaction between Zn and Fe also influences the activities of antioxidative enzymes and the uptake and homeostasis of other essential micronutrients in soybean plants.

Summary: The growth and development of S. commixta in vitro was affected by both the Fe source and pH, with plantlets showing greener leaves under pH 4.70 and 5.70. Despite higher Fe absorption at pH 4.70, Fe-EDTA combined with pH 5.70 was found to be the most beneficial for the overall growth and development of S. commixta.

Summary: Exposure to cadmium (Cd) leads to severe leaf chlorosis and reduced nutrient uptake. This study investigated how plants respond to Cd stress in the roots and its relationship to leaf chlorosis. The results showed that Cd disrupted the balance of multiple nutrient elements at different levels, particularly Mn and Fe which declined by 96% and 89% respectively, leading to leaf chlorosis. Plants actively downregulated the expression of metal transporters to reduce Cd uptake, but this also resulted in reduced uptake of Fe and Mn. Additionally, Cd stress promoted the formation of iron plaque, reducing exchangeable ions on the root surface. Importantly, ethylene played a crucial role in regulating iron plaque formation and the forms of Cd. Blocking ethylene biosynthesis increased exchangeable Cd on the root surface and decreased the percentage of iron oxides bound Cd, leading to increased Cd accumulation in the shoots. In summary, this study revealed that plants actively control the expression of metal transporters and ethylene-dependent iron plaque formation to reduce Cd uptake but sacrifice iron nutrition. The mechanism of ethylene-sequestered Cd in the rhizosphere in response to Cd stress may provide guidelines for mitigating Cd accumulation in rice.
