Antioxidant function of fungal melanin [PDF]
Journal of Bacteriology, 1993 Polyphenols have been implicated in the virulence and oxidant resistance of Cryptococcus neoformans. Although monomeric polyphenols did not protect against the prooxidant, plumbagin, polymeric dopamine-melanin conferred resistance both to hypochlorite and to permanganate.

Fungal Melanin Rewires Macrophage Metabolism
Trends in Biochemical Sciences, 2020 Aspergillus fumigatus is a deadly fungal pathogen in immunocompromised patients. A report by Gonçalves et al. reveals that melanin, a secondary metabolite present at the surface of infecting fungal spores, induces glycolysis in macrophages to promote inflammatory responses.

The Persulfate Oxidation of Fungal Melanins [PDF]
Soil Science Society of America Journal, 1983 Abstract Four fungal melanins were degraded by potassium persulfate, a new, mild chemical oxidation method. The percentage of degradation varied from 15 to 50% calculated by weight loss. Analysis of the degradation products by gas chromatography showed numerous fatty acids, both straight and branched chain, in ...

Melanin Promotes Spore Production in the Rice Blast Fungus Magnaporthe oryzae
Frontiers in Microbiology, 2022 The rice blast pathogen, Magnaporthe oryzae, spreads through spores and invades rice through appressoria. Melanin is necessary for an appressorium to penetrate plant cells, but there are many unknown aspects of its role in fungal conidiation.
