PARASITISM OF NON-HOST PLANTS BY THE MYCORRHIZAL FUNGUS TUBER MELANOSPORUM

摘要

Fungal infections in the roots of weeds growing in developing brules (areas with little vegetation) around trees infected with Tuber melanosporum (Perigord black truffle) produced severe necrosis in the root cortices. Polyclonal antibodies developed against T. melanosporum were used to demonstrate a close association between these infections and T. melanosporum, suggesting T. melanosporum was pathogenic to the weeds and was, at least in part, responsible for the brule.
