“…Until now, the remobilization of these pools has been tackled using sprays with acidic solutions aimed to lower the pH (Tagliavini et al, 1995Rombolà et al, 2000;Tagliavini and Rombolà , 2001;Abadía et al, 2004;Á lvarez-Ferná ndez et al, 2004, and references therein) as well as containing different carboxylates (Tagliavini et al, 1995Rombolà et al, 2000;Á lvarez-Ferná ndez et al, 2004), but our data support that the use of reducing compounds such as GSH can be a more efficient way of remediating or preventing Fe chlorosis in crops. Results also contribute to the growing evidence that the interplay between S and Fe in plants is relevant (Gayomba et al, 2015;Zuchi et al, 2015;Zamboni et al, 2017). Further studies should be aimed to test formulations incorporating reducing compounds such as GSH, especially in high value fruit crops heavily affected by Fe chlorosis.…”

It has been proposed that glutathione can relieve the effects of Fe deficiency. This study tested the effects of glutathione foliar treatments to prevent Fe chlorosis, using as positive controls soil and foliar Fe fertilisation. Medicago scutellata plants were grown in soil (5.7% CaCO3) supplemented or not with 4 and 8% CaCO3. Two Fe(III)‐EDDHA soil treatments (5 and 10 mg Fe kg−1), and three foliar treatments (three applications each of 2.14 mM Fe(III)‐EDDHA, 1 mM glutathione, and the previous two combined) were applied. Measurements include leaf chlorophyll and Fe concentrations, biomass, leaf enzymatic and non‐enzymatic antioxidant systems and carboxylates. The addition of CaCO3 caused typical Fe deficiency symptoms, including changes in chlorophyll, Fe, antioxidant systems and carboxylates, which were prevented by soil and foliar Fe fertilisation. The foliar treatment with glutathione also led to higher chlorophyll, leaf extractable Fe and root Fe, as well as decreases in some antioxidant systems, whereas leaf Fe concentrations decreased. The combined foliar application of glutathione and Fe was even more efficient in preventing chlorosis. Including glutathione in foliar fertilisation programs should be considered as an option for Fe chlorosis prevention, especially when relatively large leaf total Fe concentrations occur in the so called chlorosis paradox.

“…Interactions occur among the homeostatic controls of various nutrients in plants (Forieri et al, 2013;Briat et al, 2015b;Zuchi et al, 2015). However, the molecular crosstalk between Mo and Fe homeostases has been little investigated and evidence for its existence is mostly circumstantial (Bittner, 2014).…”

Molybdenum and iron mutually impact their homeostasis in cucumber (Cucumis sativus) plants

Molybdenum (Mo) and iron (Fe) are essential micronutrients required for crucial enzyme activities in plant metabolism. Here we investigated the existence of a mutual control of Mo and Fe homeostasis in cucumber (Cucumis sativus). Plants were grown under single or combined Mo and Fe starvation. Physiological parameters were measured, the ionomes of tissues and the ionomes and proteomes of root mitochondria were profiled, and the activities of molybdo-enzymes and the synthesis of molybdenum cofactor (Moco) were evaluated. Fe and Mo were found to affect each other's total uptake and distribution within tissues and at the mitochondrial level, with Fe nutritional status dominating over Mo homeostasis and affecting Mo availability for molybdo-enzymes in the form of Moco. Fe starvation triggered Moco biosynthesis and affected the molybdo-enzymes, with its main impact on nitrate reductase and xanthine dehydrogenase, both being involved in nitrogen assimilation and mobilization, and on the mitochondrial amidoxime reducing component. These results, together with the identification of > 100 proteins differentially expressed in root mitochondria, highlight the central role of mitochondria in the coordination of Fe and Mo homeostasis and allow us to propose the first model of the molecular interactions connecting Mo and Fe homeostasis.

“…Together a lack of APR and SIR should result in lower levels of reduced S compounds including glutathione. Lack of reduced S compounds should cause up-regulation of plant sulfate uptake, which explains the higher S content after Fe deficiency (Koprivova and Kopriva, 2014); indeed, Fe deficiency was shown to increase S uptake capacity in tomato and wheat (Ciaffi et al, 2013;Zuchi et al, 2015) In plant shoots, micronutrient economy, the idea that certain proteins under deficiency are preferred targets for down-regulation to benefit cofactor delivery to other essential functions, is documented for Cu (Burkhead et al, 2009) and Zn . The down-regulation at the transcript level of abundant Fe proteins, coordinated with the SUFB key factor of the Fe-S assembly system, should help to safely economize and perhaps prioritize Fe during Fe deficiency.…”
