contain large amounts of lipids, indicating provision for future germination in the host rhizosphere.
However, the accumulation, composition, and mobilization of lipids during formation and germination of these spores are largely unknown.
In this study, lipid storage and fatty acid composition during basidiosporogenesis were analyzed in fresh basidiocarps using bright-field microscopy and gas chromatography.
Abundant lipid bodies are found in the hyphae, basidia, and basidiospores of fungal basidiocarps.
This evidences a considerable C transport in the basidiocarp to meet the C demand during basidiospore formation.
Fatty acid composition analysis revealed the presence of 24 compounds with chains of 9 to 18 C atoms, either saturated or insaturated, with one or two insaturations.
The fatty ...
