Production of extracellular siderophores is typical for many plant-associated microbes, both
mutualistic and antagonistic. Various strains of mycorrhizal fungi produce siderophores, and
siderophore production by pathogenic fungi is typically associated with virulence. We
analyzed extracellular siderophore production along with production of antibacterial and
antioxidant compounds in foliar endophytic fungi of Scots pine (Pinus sylvestris L.) and
Labrador tea (Rhododendron tomentosum Harmaja). The siderophore produced in vitro was …
