Abstract

Melanin is a unique pigment with myriad functions that is found in all biological kingdoms. It is multifunctional, providing defense against environmental stresses such as ultraviolet (UV) light, oxidizing agents and ionizing radiation. Melanin contributes to the ability of fungi to survive in harsh environments. In addition, it plays a role in fungal pathogenesis. Melanin is an amorphous polymer that is produced by one of two synthetic pathways. Fungi may synthesize melanin from endogenous substrate via a 1,8-dihydroxynaphthalene (DHN) intermediate. Alternatively, some fungi produce melanin from L-3,4-dihydroxyphenylalanine (L-dopa). The detailed chemical structure of melanin is not known. However, microscopic studies show that it has an overall granular structure. In fungi, melanin granules are localized to the cell wall where they are likely cross-linked to polysaccharides. Recent studies suggest the fungal melanin may be synthesized in internal vesicles akin to mammalian melanosomes and transported to the cell wall. Potential applications of melanin take advantage of melanin's radioprotective properties and propensity to bind to a variety of substances.

  • Fungi such as Aspergillus niger and Basidiomycetes synthesize DOPA melanin through a biosynthetic pathway analogous to mammalian melanogenesis, utilizing L-DOPA as a substrate.

    “Fungi such as Aspergillus niger and Basidiomycetes synthesize DOPA melanin through a biosynthetic pathway analogous to mammalian melanogenesis, utilizing L-DOPA as a substrate [17,18,19].”

    From Fungal Melanin in Plant Pathogens: Complex Biosynthesis Pathways and Diverse Biological Functions (2025) · cites this paper as [18]

    The Melanin biosynthesis section says that some fungi use L-DOPA in a pathway resembling mammalian melanin biosynthesis. But it discusses Aspergillus niger in connection with the DHN-melanin pathway, not as an example of L-DOPA synthesis, and does not identify Basidiomycetes as a group using that pathway.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
