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.

Subcellular Compartmentalization and Trafficking of the Biosynthetic Machinery for Fungal Melanin

Cell Reports, 2016
Protection by melanin depends on its subcellular location. Although most filamentous fungi synthesize melanin via a polyketide synthase pathway, where and how melanin biosynthesis occurs and how it is deposited as extracellular granules remain elusive ...

Melanin ‘dust’ or ‘ghost’? [PDF]

Experimental Dermatology, 2016
To definitely verify the dogma of ‘melanin dust’ in the stratum corneum, Tobin et al have now reported a careful review of the literature with a vis-à-vis of the Fontana Masson (FM) and Von Kossa (VK) histochemical methods plus the Warthin-Starry (WS) stain on very thin cryosections of normal human skin and mouse pelage skin epidermis lacking ...

Radiofrequency Irradiation Mitigated UV-B-Induced Skin Pigmentation by Increasing Lymphangiogenesis

Molecules, 2022
Dermal macrophages containing melanin increase skin pigmentation since dermal melanin removal is slower than epidermal melanin removal. Lymphatic vessels are also involved in melanin clearance. We evaluated whether radiofrequency (RF) irradiation induced

The Melanin Biosynthesis Genes of Alternaria alternata Can Restore Pathogenicity of the Melanin-Deficient Mutants of Magnaporthe grisea

Molecular Plant-Microbe Interactions, 1997
The phytopathogenic fungi Magnaporthe grisea and Alternaria alternata produce melanin via the polyketide biosynthesis, and both fungi form melanized colonies. However, the site of melanin deposition and the role of melanin in pathogenicity differ between

Melanin levels in relation to vitamin D among first-generation immigrants from different ethnic groups and origins: A comparative national Canadian cross-sectional study

Frontiers in Medicine, 2023
IntroductionImmigrants to Western countries tend to have darker skin than native-born populations. We examined the relationship between skin melanin and serum vitamin D (vitD) [S-25(OH)D] levels and explored whether melanin levels explained S-25(OH)D ...
