  • Title: Role of siderophores in iron storage in spores of Neurospora crassa and Aspergillus ochraceus.
    Author: Matzanke BF, Bill E, Trautwein AX, Winkelmann G.
    Journal: J Bacteriol; 1987 Dec; 169(12):5873-6. PubMed ID: 2960664.
    Abstract:
    Spores of Neurospora crassa 74A are lacking in ferritinlike iron pools, as demonstrated by Mössbauer spectroscopic analysis. The cyclic hexapeptide siderophore ferricrocin constituted 47% of the total iron content in spores. After germination and growth, the ferricrocin iron pool disappeared, indicating that the metal was utilized. In spores of Aspergillus ochraceus, 74% of the total iron content was bound by ferrichrome-type siderophores. Siderophores may function as iron storage forms in fungal systems.
