  • Title: Isolation and characterization of some mycelia inhabiting Tuber ascomata.
    Author: Pacioni G, Leonardi M, Aimola P, Ragnelli AM, Rubini A, Paolocci F.
    Journal: Mycol Res; 2007 Dec; 111(Pt 12):1450-60. PubMed ID: 18023164.
    Abstract:
    Tuber spp. are ectomycorrhizal ascomycetes that produce subterranean ascomata known as truffles. Truffles can be regarded as complex microhabitats hosting bacteria and yeasts. In this paper we show that guest filamentous fungi are also associated to truffle ascomata, regardless of the Tuber spp., and report the morpho-molecular characterization of seven truffle-hosted mycelia isolated from healthy and intact Tuber ascomata. Some of these isolates were shown to be related to the fungal endophytes of plants. Interestingly, the truffle-hosted mycelia grew stuck to the hyphal wall of their partner when co-cultivated with the Tuber borchii mycelium, but not when co-cultivated with the test species Agaricus macrosporus. The present data suggest that guest filamentous fungi can be added to the list of truffle-interacting microorganisms.
