- Abstract
- A sterile mycelium PSIV, an ascomycete capable of establishing ericoid
mycorrhizas, was used to investigate how zinc ions affect the cellular
mechanisms of fungal growth. A significant reduction of the fungal
biomass was observed in the presence of millimolar zinc concentrations;
this mirrored conspicuous changes in hyphal morphology which led to
apical swellings and increased branching in the subapical parts.
Specific probes for fluorescence and electron microscopy localised
chitin, the main cell wall polysaccharide, on the inner part of the
fungal wall and on septa in control specimens. In Zn-treated mycelium,
hyphal walls were thicker and a more intense chitin labelling was
detected on the transverse walls. A quantitative assay showed a
significant increase in the amount of chitin in metal-treated hyphae.
