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 plants that deploy a phosphorus -mobilising strategy based on the release of carboxylates tend to have high leaf manganese concentrations this occurs because the carboxylates mobilise not only soil inorganic and organic but also a range of micronutrients, including mn.
