Fe deficiency is a major challenge that limits agricultural productivity and is a serious human health concern worldwide. Under iron-limiting conditions soil microorganisms produce siderophores, that chelates Fe3+ (ferric) and make it available to the plants. Selection of efficient siderophore producing bacteria and establishing their …

Iron sulphate, also known as ferrous sulphate or copperas, is a chemical compound with the formula FeSO4. It is a blue-green crystalline solid that is soluble in water. Iron sulphate is a common fertilizer and is used to treat iron deficiency in plants. It is also used in the production of inks, dyes, and pigments.

The higher Mn concentration in plant litter from ECM plants could be attributed to the interaction of Mn with higher lignin concentration. For example, evidence suggests that Mn is important for lignin degradation ( Berg et al., 2007 ; Berg et al., 2013 ) and thus higher Mn concentration will facilitate the lignin degradation process.

These regulatory processes help to avoid plant iron concentrations building up to potential cell functioning disruptions that could adversely affect plant fitness. Indeed, when iron is in excess in the plant, it can lead to the production and accumulation of dangerous reactive oxygen species and free radicals (H 2 O 2, HO •, O 2 •−, HO ...

Background Plants require iron for a large number of metabolic processes. Due to its low availability in high pH soils, and the impaired acquisition by roots, iron chlorosis is one of the most important limiting factors on plant development in many countries.

6. Plant secondary metabolites and abiotic stress tolerance. Metabolic processes that lead to the accumulation of natural products are affected by the concentrations of various PSMs, which greatly affect growth conditions. Numerous typical reactions occur when abiotic stresses affect the stimulation of PSMs.

concentration 'window of Fe uptake' in which plants can benefit from phytosiderophore-mediated Fe uptake. In plants from both strategies, insoluble Fe pools might be detected in the apoplast as well as in the root surface, the so-called iron plaque.
