Fungal morphogenesis induced by natural and synthetic substances: Herniarin-induced alterations in the dermatophyte Microsporum cookie Ajello

Abstract

The effects of either synthetic or natural substances on the normal morphogenetic processes in fungi are reviewed. Original results concerning the changes induced in the dermatophyte Microsporum cookei Ajello by the UVA-activated coumarin, herniarin, are reported. Alterations in the shape and wall assembly of parietal components are discussed on the basis of the most recent knowledge on the formation and growth of fungal hyphae.
