  • Title: Arbuscular mycorrhizal fungal diversity in the Tuber melanosporum brûlé.
    Author: Mello A, Lumini E, Napoli C, Bianciotto V, Bonfante P.
    Journal: Fungal Biol; 2015 Jun; 119(6):518-27. PubMed ID: 25986549.
    Abstract:
    The development of the fruiting body (truffle) of the ectomycorrhizal fungus Tuber melanosporum is associated with the production of an area (commonly referred to with the French word brûlé) around its symbiotic plant that has scanty vegetation. As truffles produce metabolites that can mediate fungal-plant interactions, the authors wondered whether the brûlé could affect the arbuscular mycorrhizal fungi (AMF) that colonize the patchy herbaceous plants inside the brûlé. A morphological evaluation of the roots of plants collected in 2009 from a T. melanosporum/Quercus pubescens brûlé in France has shown that the herbaceous plants are colonized by AMF to a great extent. An analysis of the 18S rRNA sequences obtained from roots and soil inside the brûlé has shown that the AMF community structure seemed to be affected in the soil inside the brûlé, where less richness was observed compared to outside the brûlé.
