WebJan 1, 2013 · Ferricrocin is a widespread siderophore in forest soils that seems to be resistant to the proteases excreted by plants and Gram-positive bacteria (Winkelmann 2007). It is now considered that organic non-siderophore ligands, as several amino acids and organic acids like citrate, can be exudated by plants and influence the iron availability. WebJul 2, 2010 · Siderophores are biosynthetically produced and secreted by many bacteria, yeasts, fungi and plants, to scavenge for ferric iron (Fe3+). They are selective iron-chelators that have an extremely high affinity for binding this trivalent metal ion. The ferric ion is poorly soluble but it is the form of iron that is predominantly found in oxygenated environments. …
