Frequency of the two mating types in the soil under productive and non-productive trees in five French orchards of the Périgord black truffle (Tuber melanosporum Vittad.)
The Périgord black truffle (Tuber melanosporum Vittad.) is an ectomycorrhizal fungus forming edible fructifications. The production of T. melanosporum relies mainly on man-made plantations. T. melanosporum is a h...

Certainties and uncertainties about the life cycle of the Périgord black truffle (Tuber melanosporum Vittad.)
Several aspects of the life cycle of the Périgord black truffle have been elucidated only recently, while others remain either controversial or unstudied. In this paper, we present a revised li...

SSR-based identification of genetic groups within European populations of Tuber aestivum Vittad
Tuber species are ectomycorrhizal ascomycetes establishing relationships with different host trees and forming hypogeous fruiting bodies known as truffles. Among Tuber species, Tuber aest...

Identification and In Situ Distribution of a Fungal Gene Marker: The Mating Type Genes of the Black Truffle
Truffles are ectomycorrhizal fungi harvested mainly in human managed agroforestry ecosystems. Truffle production in truffle orchards faces two important bottlenecks or challenges: the initiation of the sexual ...

Tools to Trace Truffles in Soil
Different methodological tools have been developed to trace truffles in soil, from fruiting body collections and mycorrhiza morphoty** to recent high-sensitive, molecular techniques able to detect specific t...

Seasonal dynamics of Boletus edulis and Lactarius deliciosus extraradical mycelium in pine forests of central Spain
The annual belowground dynamics of extraradical soil mycelium and sporocarp production of two ectomycorrhizal fungi, Boletus edulis and Lactarius deliciosus, have been studied in two different pine forests (Pinar...

Quantification of extraradical mycelium of Tuber melanosporum in soils from truffle orchards in northern Spain
Quantification of extraradical mycelium of black truffle (Tuber melanosporum) has been carried out in a natural truffle ground and in seven truffle orchards (around 20 years old) established in Tierra Estella and...

Quantification of extraradical soil mycelium and ectomycorrhizas of Boletus edulis in a Scots pine forest with variable sporocarp productivity
The availability of most edible ectomycorrhizal mushrooms depends on their natural fructification. Sporocarp formation of these fungi is linked to habitat characteristics and climate conditions, but these data...

Intraspecific variability of Lactarius deliciosus isolates: colonization ability and survival after cold storage
Intraspecific variability in root colonization, extraradical growth pattern, and survival after cold storage of Lactarius deliciosus isolates was determined in pure culture conditions using Pinus pinaster as a ho...
