Because of its ability to readily change oxidation state in biological systems, Mn plays and important role in a broad range of enzyme-catalyzed reactions,
Abstract. This review aims to relate some aspects of plant growth to the physiological functions of Mn within the plant. Yields of crops, pastures and trees are affected adversely by either deficiencies or excesses (toxicities) of Mn. Concomitantly, symptoms of the disorder usually but not always appear on leaves, roots or fruits.
2022年9月16日 Introduction. Manganese (Mn) is an essential micronutrient for plants, acting as a co-factor and activator of many enzymes. Mn plays prominent roles in the oxygen-evolving complex (OEC) of photosystem II (PSII) and superoxide dismutase (Alscher et al., 2002; Shen, 2015; Schmidt et al., 2016; Schmidt and Husted, 2019).Plants are
2019年9月27日 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 metal ions, such as Mg(II), which ...
2005年3月1日 This review provides a broad overview of the long distance and cellular transport as well as detoxification and homeostasis mechanisms of Mn and Cu, which are essential micronutrients but extremely toxic at elevated concentrations. Heavy metals like Mn and Cu, though essential for normal plant growth and development, can be toxic
2023年6月8日 Manganese (Mn) is an essential micronutrient in plants, and it is necessary for hydrolysis in photosystem II, chlorophyll biosynthesis, and also chloroplast breakdown. Limited Mn availability in light soil resulted in interveinal chlorosis, poor root development, and the development of fewer tillers, particularly staple cereals including wheat, while
2020年3月26日 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).
In plants Mn has a role in many biochemical processes. However, unlike other essential trace elements such as Cu, Zn, Fe and Mo which are usually integral components of enzymes, Mn usually acts as an activator of
2022年3月29日 The most frequently observed morphological symptoms of Mn toxicity include chlorotic and necrotic changes in the leaves. Two hypotheses are known to explain the formation of these changes in plant tissues under manganese stress (Fernando and Lynch, 2015).The first hypothesis—apoplastic—assumes the formation of damage as a
Abstract. Manganese in plant cells can exist as a cation, in various complexée! states or can form metallo-proteins in which tightly bound Mn atoms probably produce an appropriate protein conformation. In addition a redox function for Mn seems likely in water splitting on the oxidant side of photosystem II The quantitative requirements for Mn ...
Manganese is about the tenth most abundant element in the earth’s upper continental crust with an average abundance of 650 mg kg-1 Mn. More than 250 minerals contain Mn as an essential constituent and several thousand minerals contain Mn as a minor substituent for essential structural ions such as Fe 2+ and Mg 2+.In this chapter the occurrence of Mn in
2017年3月1日 Plants Accumulate More Mn Than They Require. Manganese (Mn) was demonstrated to be essential for plants in 1922 by McHargue [1] and for animals in 1931 by Kemmerer et al.

Uptake of Mn 2+ by roots according to Millaleo et al. is a biphasic process.The initial rapid reversible and non-metabolic process is caused by absorption of Mn 2+ by negatively charged cell wall constituents of root-cell apoplastic spaces (Humphries et al. 2007).The second phase, which involves transport into the symplast, is slow since it depends on

Manganese (Mn) is one of the essential trace elements for plant growth, which is involved in photosynthesis, while overdose of Mn in plants would interfere with the absorption and utilization of other mineral elements, influence energy metabolism, depress photosynthetic rates, and lead to oxidative stress (Fernando
Manganese (Mn), an essential trace element, is important for plant health. In plants, Mn serves as a cofactor in essential processes such as photosynthesis, lipid biosynthesis and oxidative stress. Mn deficient plants exhibit decreased growth and yield and are more susceptible to pathogens and damage at freezing temperatures. Mn deficiency is most
