  Advances in the Mechanisms of Plant Tolerance to Manganese Toxicity

  20191014 · Manganese (Mn) is an essential element for plant growth due to its participation in a series of physiological and metabolic processes. Mn is also considered a heavy metal that causes phytotoxicity when present in excess, disrupting photosynthesis and enzyme activity in plants. Thus, Mn toxicity is a major constraint limiting plant growth …

  Manganese (Mn) Nutrient Deficiencies In Plants

  Manganese toxicity disrupts indole acetic acid homeostasis and suppresses the CO2 assimilation reaction in rice leaves. It is found that under excess Mn conditions, CO2 assimilation was inhibited by stomatal closure, and both carbon anabolic and catabolic activities were decreased, and indole acetic acid concentration was decreases, and auxin ...

  Manganese Deficiency in Plants: The Impact on Photosystem II

  Manganese (Mn) is an essential plant micronutrient with an indispensable function as a catalyst in the oxygen-evolving complex (OEC) of photosystem II (PSII). Even so, Mn deficiency frequently occurs without visual leaf symptoms, thereby masking the distribution and dimension of the problem restricting crop productivity in many places of the world. …

  Manganese toxicity in tomato plants: effects on cation …

  199051 · Manganese concentration in the shoot tissues ranged from 286 to 4240 μg. g‐1 dry weight. The high Mn concentration values found in the shoot tissues of the toxic plants indicate that Mn was highly mobile in the xylem as confirmed by xylem sap analysis. The concentrations of both Ca and Mg were lower in the smaller Mn toxic plants.

  Transport, functions, and interaction of calcium and manganese in plant ...

  2021124 · Calcium (Ca2+) and manganese (Mn2+) are essential elements for plants and have similar ionic radii and binding coordination. They are assigned specific functions within organelles, but share many transport mechanisms to cross organellar membranes. Despite their points of interaction, those elements are usually investigated and reviewed …

  Distribution and Movement of Manganese in Plants

  The distribution of Mn in plants is strongly affected both by its accumulation and release by specific cells and organs and by its movement in the xylem and phloem saps. It is an important factor in the development and expression of Mn deficiency and in the relationship between yield and Mn concentrations in plant parts.

  The Biochemical Properties of Manganese in Plants

  2019927 · Manganese (Mn) is an essential micronutrient with many functional roles in plant metabolism. Manganese acts as an activator and co-factor of hundreds of metalloenzymes in plants. 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, …
