To acquire iron, many plant species reduce soil Fe(III) to Fe(II) by Fe(III)-chelate reductases embedded in the plasma membrane of root epidermal cells. The reduced product is then taken up by Fe(II) transporter proteins. These activities are induced under Fe deficiency. We describe here the FRO1 gene from pea (Pisum sativum), which encodes an Fe(III)-chelate reductase. Consistent with this pro...

Nanofertilizers can be used as potential contenders to provide macro- and micronutrients plants. Specifically, iron-oxide-based engineered nanoparticles are promising candidates for next-generation iron-deficiency fertilizers. Aiming investigate the effect of Fe2O3 magnetic on plant germination growth, alfalfa seeds were presoaked by a series concentrations (0, 50, 100, 150, 200 mg/L) NPs in th...

Regulation exerted by the iron status of the plant on the iron deficiency responses was investigated in cucumber roots (Cucumis sativus L.) both at the biochemical and molecular level. Absence of iron induced the expression of the CsFRO1, CsIRT1, CsHA1 and the Cspepc1 transcripts that was followed by an increase in the corresponding enzymatic activities. Supply of iron repressed gene expression...

Iron (Fe) deficiency chlorosis (IDC) affects the growth of several crops, especially when growing in alkaline soils. The application synthetic Fe-chelates is one most commonly used strategies IDC amendment, despite their associated negative environmental impacts. In a previous work, Fe-chelate tris(3-hydroxy-1-(H)-2-methyl-4-pyridinonate) iron(III) [Fe(mpp)3] has shown great potential for allev...

Nowdays, iron nanoparticles due to their unique characteristics are used in all of sciences and technology. These nano particles due to their electrical, magnetic, optical and catalytic properties and having high area and activity that is promped by their small size and most importantly many scientists from the entire world are interested in their low cost production. In this project we used me...

sis usually involve chaotropic agents such as guanidinium chloride and (or) detergents for the dissociation of iron at an acidic pH from transferrin. Reduction is achieved with various reducing compounds such as ascorbic acid, hydroxylamine, thioglycolic acid, and others. Among these, ascorbic acid is unique in its property not only to reduce but also to chelate iron. This property appears to b...
