Manganese Cluster in Photosynthesis: Where Plants Oxidize Water to Dioxygen.
The essential involvement of manganese in photosynthetic water oxidation was implicit in the observation by Pirson in 1937 that plants and algae deprived of Mn in their growth medium lost the ability to evolve O2. Addition of this essential element to the growth medium resulted in the restoration of water oxidation within 30 min. There is increased interest in the study of Mn in biological chem...
متن کاملMn-euvering manganese: the role of transporter gene family members in manganese uptake and mobilization in plants
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 prominent on alkaline soils with approximately ...
متن کاملElevated Phosphorus Impedes Manganese Acquisition by Barley Plants
The occurrence of manganese (Mn) deficiency in cereal crops has increased in recent years. This coincides with increasing phosphorus (P) status of many soils due to application of high levels of animal manure and P-fertilizers. In order to test the hypothesis that elevated P my lead to Mn deficiency we have here conducted a series of hydroponics and soil experiments examining how the P supply a...
متن کاملInterrelationship of Iron and Manganese Supply in Growth, Chlorophyll, and Iron Porphyrin Enzymes in Barley Plants.
Somers and Shive (37) suggested that the physiological availability of iron in plants is determined by the relative manganese supply and that the optimum growth and yield of plants depend on a certain definite proportion rather than the absolute level of iron and manganese supply. These workers also held that iron deficiency is identical with manganese excess and iron excess with manganese defi...
