domestically since 1970. Manganese ore was consumed mainly by six firms with plants principally in the East and Midwest. Most ore consumption was related to steel production, either directly in pig iron manufacture or indirectly through upgrading the ore to ferroalloys. Manganese ferroalloys were produced at two plants. Additional quantities of

Abstract. Manganese (Mn) is an important micronutrient for plant growth and development and sustains metabolic roles within different plant cell compartments. The metal is an essential cofactor for the oxygen-evolving complex (OEC) of the photosynthetic machinery, catalyzing the water-splitting reaction in photosystem II (PSII).

Manganese(II) is the prevalent oxidation state of Mn in plants and exhibits fast ligand exchange kinetics, which means that Mn can often be substituted by other …

Understanding the distribution of elements within plant tissues is important across a range of fields in plant science. In this review, we examine synchrotron-based x-ray fluorescence microscopy (XFM) as an elemental imaging technique in plant sciences, considering both its historical and current uses as well as discussing emerging approaches.

Manganese is one of nine essential nutrients that plants require for growth. Many processes are dependent on this nutrient, including chloroplast formation, photosynthesis, nitrogen metabolism, and synthesis of some enzymes. This role of manganese in plants is extremely crucial. Deficiency, which is …

Manganese, a group VII element of the periodic table, plays an important role in biological systems and exists in a variety of oxidation states. The normal level of Mn in air surrounding major industrial sites is 0.03 μg/m3, in drinking water 0.05 mg/liter and in soil between 560 and 850 ppm.Manganese is an essential trace element for higher plant systems. It is …

Manganese is acquired from the rhizosphere solution as Mn 2+ by roots of all plant species and also as Mn-phytosiderophore complexes by roots of graminaceous species (Alejandro et al. 2020; Curie et al. 2009; White and Pongrac 2017).In aerated soils Mn is present in the soil solution as Mn 2+, although a significant amount can be present …

of plants may become excessive under the influence of sufficiently great amounts of manganese, resulting in the auto-oxidation of the chloroplastids, thus destroying the green pigment. SALOMONE (IO), on the other hand, found evidences of plasmolysis in wheat that had been fertilized with manganese dioxide at the rate of fifty kilograms per hectar.

Manganese also plays a role in blood clotting and hemostasis in conjunction with vitamin K . Manganese is absorbed in the small intestine through an active transport system and, possibly, through diffusion when intakes are high . After absorption, some manganese remains free, but most is bound to transferrin, albumin, and plasma alpha-2 ...

Micro-particle induced X-ray emission was employed to investigate the spatial distribution of magnesium (Mg), calcium (Ca) and manganese (Mn) in the young and old leaves of tea plants grown in the absence and …

X-ray fluorescence spectroscopy (XRF) is an analytical tool used to determine the elemental composition in a myriad of sample matrices. Due to the XRF non-destructive feature, this technique may allow time-resolved plant tissue analyses under in vivo conditions, and additionally, the combination with other non-destructive techniques.
