More than 70% of vascular plant species live in symbiosis with arbuscular mycorrhizal (AM) fungi. In addition to other effects this symbiosis is known for its significance for plant nutrition including iron. Fungal iron mobilization from soil is comm

Most fungi are known to synthesize siderophores under iron limitation. However, arbuscular mycorrhizal fungi (AM fungi) have so far not been reported to produce siderophores, although their metabolism is iron-dependent. In an approach to isolate side

A novel trishydroxamate siderophore, named basidiochrome, was isolated as the principal siderophore from low-iron culture filtrates of Ceratobasidium and Rhizoctonia species which are known as mycorrhizal fungi associated with orchid roots. Ion-excha

The siderophore salmochelin is produced under iron-poor conditions bySalmonellaand many uropathogenicEscherichia colistrains. The production of salmochelin, a C-glucosylated enterobactin, is dependent on the synthesis of enterobactin and theiroBCDENg

Escherichia coli strains produce a variety of structurally different siderophores of which enterobactin, aerobactin and yersiniabactin have been reported earlier to occur in strains of extraintestinal infections. In uropathogenic E. coli (UPEC) strai

Experiments were conducted to assess the distribution of foliar applied Fe-containing compounds using microbial siderophores. Fe was measured in leaf fluid obtained by centrifugation according to a determination method based on Fe chelation by desfer

Staphyloferrin A, the iron-transporting siderophore of Staphylococci, contains two citric acid residues linked to a D-ornithine backbone, having thus three chiral centers. While the chirality of the backbone can be determined after hydrolysis, the ch

Experiments to assess the re-greening and the distribution of leaf-applied iron (Fe) within the aerial organs were developed with tobacco (Nicotiana tabacum L.) plants. Fe (III)-citrate and Fe-dimerum acid were applied to a part of the leaf and plant
