Cold plasma and ozone sanitation of irrigation solutions can oxidize both microbes non-target micronutrients because their high oxidation-reduction potential (ORP) is a non-selective mode action. The objective this study was to evaluate the effects cold treatment on oxidation iron manganese in nutrient containing one four chelates (iron-ethylenediaminetetraacetic acid (Fe-EDTA), iron-diethylene...

At present fertilizer has become essential to modern agriculture to feed the growing population. Though chemical fertilizers increase crop production; their overuse has hardened the soil, decreased fertility, strengthened pesticides, polluted air and water, and released greenhouse gases, thereby bringing hazards to human health and environment as well. Due to the adverse effect of chemical fert...

Reduction of Fe(3+) to Fe(2+) is a prerequisite for Fe uptake by tomato roots. Ferric chelate reductase activity in plasma membranes (PM) isolated from roots of both iron-sufficient (+Fe) and iron-deficient (-Fe) tomatoes (Lycopersicon esculentum Mill.) was measured as NADH-dependent ferric citrate reductase and exhibited simple Michaelis-Menten kinetics for the substrates, NADH and Fe(3+)(citr...

Iron deficiency is the most common nutritional disorder in the world. Our goal is to alleviate this problem by enriching the grain of the Oryza sativa staple crop (rice) with iron. Ferric chelate reductase is a gene involved in the uptake and transport of iron and is expressed ubiquitously in the plant. We successfully generated an O. sativa ferric chelate reductase promoter-terminator fusion a...

To identify possible iron sources for bacteroids in planta, soybean (Glycine max L. Merr.) symbiosomes (consisting of the bacteroid-containing peribacteroid space enclosed by the peribacteroid membrane [PBM]) and bacteroids were assayed for the ability to transport iron supplied as various ferric [Fe(III)]-chelates. Iron presented as a number of Fe(III)-chelates was transported at much higher r...

This Research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated Fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. Applied nutrients were zinc sulphate (Zn) of 0.0 and 1.5gl-1 and urea (N) at 0.0 and 5 gl-1 and Fe (1) control (low Fe)...

HO (haem oxygenase) catalyses the degradation of haem to biliverdin, CO and ferrous iron via three successive oxygenation reactions, i.e. haem to alpha-hydroxyhaem, alpha-hydroxyhaem to alpha-verdohaem and alpha-verdohaem to ferric biliverdin-iron chelate. In the present study, we determined the crystal structure of ferrous alpha-verdohaem-rat HO-1 complex at 2.2 A (1 A=0.1 nm) resolution. The ...

The electronic structures of pyridine N-heterocyclic dicarbene (iPrCNC) iron complexes have been studied by a combination of spectroscopic and computational methods. The goal of these studies was to determine if this chelate engages in radical chemistry in reduced base metal compounds. The iron dinitrogen example (iPrCNC)Fe(N2)2 and the related pyridine derivative (iPrCNC)Fe(DMAP)(N2) were stud...

Iron deficiency-induced chlorosis is a widespread horti-/agricultural problem that can lead to massive crop failures, especially for plants growing on calcareous soils. The most effective agronomical practice prevent from iron deficiency apply synthetic Fe-(chelate)-fertilizers the soil. Because these compounds are usually not biodegradable and, therefore, may become soil contaminants, efficien...
